DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device used for lifting a heavy object to be suspended using a crane.

[0002] The present invention also relates to a method of mounting a unit for housing construction used when a unit for housing construction is lifted using a crane and mounted on a foundation or a unit.

[0003]

2. Description of the Related Art Generally, when a suspended object, for example, a relatively heavy building material produced in a factory is loaded on a carrier of a transport vehicle, or the building material is transferred from the carrier of the transport vehicle to a predetermined position on a building site. For lowering, a crane is used.
For example, in the case of the latter, after performing a slinging operation and a locking operation of a hook of a crane to a wire, the hoisting operation is carried out, moved to a predetermined position on a construction site, and then suspended.

However, if the center of gravity of the building material does not coincide with the position (support point) of the hook, it is not preferable because the building material is tilted. Therefore, immediately after a building material is lifted by a crane, a configuration for automatically matching the center of gravity of the building material with the position of the hook has been devised, and is disclosed in Japanese Utility Model Laid-Open No. 55-164289. Hereinafter, the configuration disclosed in this publication will be briefly described.

[0005] As shown in FIG.
A wire 202 is attached to a circular hole of the suspension fitting 200, and a hook 204 of the crane is locked to the wire 202. The lower end of the hanging fitting 200 is connected to an automatic decentering device 206 described later, and the automatic decentering device 206 is fixed to a long beam 208. Chains 21 are provided on the lower surfaces of both ends of the beam 208, respectively.
0 is attached to one end. An electromagnet 212 is attached to the lower end of the chain 210, and a construction material such as an H-shaped steel (not shown) is attracted by the electromagnet 212.

FIG. 12 shows the automatic decentering device 206 described above.
Is shown. As shown in this figure,
A pair of bearing boxes 2 is provided on the upper end surface of the beam 208.
14 are fixed, and these bearing boxes 2
Both ends of one screw shaft 216 are supported by 14. One end of the screw shaft 216 is connected to an output shaft of the motor 220 via a coupling 218. Therefore, when the output shaft of the motor 220 rotates, the screw shaft 216 rotates around its axis. The screw shaft 216 has
The fixing nut 222 attached to the lower end of the above-mentioned hanging fitting 200 is screwed. Further, the hanging fitting 20
A pair of rollers 224 are arranged on both sides of the zero. These rollers 224 roll on rails 228 provided on the back surface of the upper plate 226. In addition, a slit 230 is formed in the middle part of the upper plate 226 in the width direction for a relative movement stroke of the hanging fitting 200.

The above-described automatic decentering device 206 includes an inclination detector 232. Inside the tilt detector 232, a predetermined amount of mercury is stored, and a pair of electrodes are arranged at positions separated from the mercury surface by a predetermined distance. When the building material tilts, the tilt detector 232 itself also tilts, so that one of the electrodes comes into contact with the mercury surface and the tilt of the building material is detected. When the inclination of the building material is detected by the inclination detector 232, the motor 220 is rotated forward or backward until the building material becomes horizontal.

[0008]

According to the above-described structure, the object to be detected as to whether or not the inclination is detected by the inclination detector 232 is the beam 208, so that the upper surface of the suspended object in the lifted state can be leveled. There are things that cannot be done.
Hereinafter, this will be described with reference to FIGS. 13 and 14 in which each element is modeled.

FIG. 13 (A) shows a suspended object 250 having a uniform load distribution (as shown in FIG. 13 (A), a load of X [kg] acts on the suspended object 250 on both sides. Is lifted by the beam 252 and the wire 253. In this case, if the hanging member 254 is positioned at the center of the beam 252, the moments at both ends of the beam 252 are balanced, and the upper surface of the suspended object 250 is horizontal. Further, FIG. 13B shows a suspended object 256 having a nonuniform load distribution (as shown in FIG. 13B, a load of Y kg is applied to the left side of the suspended object 256. The right side shows a state where a load of X (kg) (<Y (kg) is applied) is lifted by the beam 252 and the wire 253. In this case, if the hanging bracket 254 is arranged at the center of the beam 252, the condition for balancing the moment at both ends of the beam 252 is not satisfied, and the suspended object 256 tilts to the left. Therefore, the hanging fitting 254 is moved to the left by the automatic decentering device. Thus, the moments at both ends of the beam 252 are balanced, and the upper surface of the suspended object 256 becomes horizontal. The above is the description of the span length of the beam 252 and the suspended object 250.
(Or the object 256 to be suspended) in the longitudinal direction.

FIG. 13 (C) shows a suspended object 258 having a uniform load distribution (as shown in FIG. 13 (C), a load of Z [kg] acts on the suspended object 258 on both sides. However, the longitudinal dimension of the suspended object 258 is the beam 252.
Is longer than the span length of the beam 252 and the wire 25
3 shows a state of being lifted. In this case, since the horizontal component and the vertical component of the tension acting on the wire 253 at both ends of the beam 252 are equal to each other, if the hanging member 254 is located at the center of the beam 252, the vertical And each of the wires 253 make an angle θ, and the upper surface of the suspended object 258 becomes horizontal.

On the other hand, as shown in FIG. 14A, a suspended object 260 having a non-uniform load distribution (as shown in FIG. 14A, the load P [ k
g] acts, and a load Q [kg] (<P [kg]) is applied to the right side.
Is lifted by the beam 252 and the wire 253, the system behaves as follows.

That is, since the tension acting on the left wire 253 is T ₁ and the tension acting on the right wire 253 is T ₂ (<T ₁ ), the horizontal component and the vertical component of the left and right tensions are also reduced. Of course it will be different. Therefore, hanging bracket 254 when it is positioned in the center of the beam 252 towards the moment due to the vertical component force T ₁ is greater than the moment due to the vertical component force T _2. Therefore, the beam 252 rotates counterclockwise about the hanging bracket 254. However, as shown in FIG. 14B, the position of the hanging member 254 is moved to the left by the automatic decentering device, so that the beam 252 itself is in a horizontal state. Accordingly, at this point, the operation of the automatic decentering device also stops. It should be noted that even if the balance condition by the vertical component is satisfied, the imbalance due to the horizontal component still remains, so that the beam 252 slightly moves to the left until the two horizontal components match.

However, the fact that the left and right vertical component forces are in a balanced state in a different state means that the direction of action of the vertical component force (vertical direction) due to the tension T ₃ and the angle θ ₁ between the left wire 253 and the angle θ ₁ . Is smaller than the angle θ ₂ formed between the direction of action of the vertical component force due to the tension T ₄ and the wire 253 on the right side. Accordingly, a situation occurs in which the upper surface of the suspended object 260 is inclined although the beam 252 is horizontal.

In general, the invention disclosed in this publication detects the inclination of the beam 262 in the α direction as shown in FIG. 15 and moves the position of the hanging fitting 264 based on the detected inclination. Although the inclination of the suspended object 266 in the β direction is eliminated, the span length of the beam 262 does not match the longitudinal dimension of the suspended object 266, and the suspended object 2
If the load distribution 66 is uneven, the inclination in the β direction cannot be eliminated, and the inclination of the suspended object 266 in the γ direction cannot be dealt with in the first place.

Thus, when the object to be hung is a unit for housing construction, the above-mentioned problem becomes conspicuous.
Because, in general, there are several types of longitudinal dimensions of units for housing construction, it is common that the span length of the beam does not match the longitudinal dimension of the unit, and various elements are installed inside the unit at the factory. This is because, in most cases, the load distribution becomes uneven distribution in most cases. As a result, the unit is lifted with its upper surface inclined with respect to the horizontal plane, and there is a problem that the lifting state of the unit becomes unstable. Furthermore, when placing the unit in the unstable state on the upper surface of the foundation or the like, it is necessary for the operator to place the unit while making fine adjustments, so that the placing operation cannot be performed smoothly. However, there is a problem that it takes a long working time.

SUMMARY OF THE INVENTION In view of the above facts, it is a first object of the present invention to provide a lifting device capable of lifting a suspended object in an appropriate state even when the suspended object having a nonuniform load distribution is lifted. Further, it is a second object of the present invention to provide a method of mounting a unit for housing configuration, which allows the unit for housing configuration to be mounted on an upper surface of a foundation in an appropriate state.

[0019]

The operation of the present invention described in claim 1 is as follows.

First, a plurality and the same lengths locked to the suspended object
The suspended object side wire and the crane side wire are connected by connecting means. Thereafter, the suspended object is lifted by operating the crane. If the upper surface of the suspended object is inclined with respect to the reference plane when the suspended object is lifted, the support point of the suspended object side wire and the crane side wire with respect to the connecting means is changed by the adjusting means. . When the support point of the suspended object side wire and the crane side wire with respect to the connecting means is changed, the inclination of the upper surface of the suspended object with respect to the reference plane is also changed, and the inclination of the upper surface of the unit with respect to the reference plane is eliminated. .

For example, when an object to be suspended is preferably lifted with the upper surface being horizontal, the reference plane may be assumed to be a horizontal plane. In this case, if the upper surface of the suspended object in the lifted state is inclined with respect to the horizontal plane, the adjusting operation is performed by the adjusting means (that is, the operation of changing the support points of the suspended object side wire and the crane side wire with respect to the connecting means). Is performed. As a result, the upper surface of the suspended object becomes horizontal.

For example, when an object to be suspended is preferably lifted with the upper surface inclined at a predetermined angle with respect to the horizontal plane, the reference surface may be assumed to be a surface inclined at a predetermined angle with respect to the horizontal plane. In this case, if the upper surface of the suspended object in the lifted state is inclined with respect to the reference plane, an adjusting operation is performed by the adjusting means. As a result, the upper surface of the suspended object is lifted in a state of being inclined at a predetermined angle with respect to the horizontal plane. In addition, according to the present invention, the connecting means is constituted by combining three elongated beam portions each arranged with the predetermined direction as the longitudinal direction, and the adjustment by the adjusting means is performed by adjusting the longitudinal direction of the beam portion. Since it is performed along the direction, the total center of gravity position of the suspended object can be obtained in a wide range. Moreover, according to the present invention, the connecting means for connecting the suspended object-side wire and the crane-side wire is configured by combining three elongated beam portions each arranged with a predetermined direction as a longitudinal direction. Since a mounting base plate or the like for connecting means or the like is not used, the device can be reduced in size and weight, and can be easily transported to the site. Also,
According to the present invention, three elongated vias forming the connecting means are provided.
Since the beam sections are locked together, the beam sections
One system with enough degrees of freedom to displace

One length, the length of any suspended object side wire
Should not be adjusted so that
No. Furthermore, the angle between the upper surface of the suspended object and the suspended object side wire
There are no restrictions on the degree. Therefore, the remaining beam connecting the two beams

It is. In other words, the present invention maintains the idea of wire suspension.
While physically adjusting the length of the suspended object side wire
Instead of physically adjusting the length of the suspended object side wire.
It has the same effect as described above. Therefore, suspended
A place to balance by physically adjusting the length of the object side wire
In such a case, there is a possibility that distortion (deformation) may be given to the suspended object.
However, according to the present invention, the object to be suspended is distorted (deformed).
There is no fear. The operation of the present invention described in claim 2 is as follows. The main support of the main suspension is locked to the crane-side wire. Further, the sub-supporting portions of the pair of sub-hangers are respectively locked to both ends in the longitudinal direction of the main beam portion of the main hanger. In the state after the locking, the pair of sub-beam portions are arranged orthogonal to the main beam portion and parallel to each other. A pair of suspended object-side wires having the same length are locked to both ends in the longitudinal direction of these sub-beam portions. As a result, the object-side wire and the crane-side wire are connected via the three hanging members. Thereafter, the suspended object is lifted by operating the crane. When the upper surface of the object to be suspended is inclined with respect to the reference plane when the object to be suspended is lifted, the pair of sub-adjustment means operate independently and independently, and each sub-hook on the upper surface of the object to be suspended is provided. Are moved in the longitudinal direction of each sub beam portion so that the inclination along the reference plane with respect to the reference plane is eliminated. That is, by the adjustment by each sub-adjustment means,
Each sub-support is located at the position of the center of gravity in the direction along each sub-hanger. Since the pair of sub-supporting portions are locked at both ends in the longitudinal direction of the main beam portion, when each of the sub-supporting portions moves to the position of the center of gravity as described above, the relative position of the main hanging member to the pair of sub-hanging members is reduced. The position is also changed. Thereafter, the main adjusting means is operated, and the main support is moved in the longitudinal direction of the main beam portion so that the inclination of the upper surface of the object to be suspended along the main suspending tool with respect to the reference plane is eliminated. That is, by the adjustment by the main adjusting means, the main support portion is located at the position of the center of gravity in the direction along the main hanging tool, and the position of the center of gravity becomes the total position of the center of gravity of the suspended object. Therefore, the object to be suspended can be lifted in an appropriate state. In addition, according to the present invention, the pair of sub-beam portions are arranged orthogonal to and parallel to the main beam portion, and the main support portion is movably supported along the longitudinal direction of the main beam portion. Further, since each sub-support portion is supported so as to be movable along the longitudinal direction of each sub-beam portion, the adjustable width can be increased. Therefore, the total center of gravity position of the suspended object can be obtained in a wide range. Moreover, according to the present invention, since the mounting base plate and the like are not used as is apparent from the configuration of the main suspension and the pair of sub suspensions, the apparatus can be reduced in size and weight, and can be easily transported to the site. Can be achieved. Ma
Further, according to the present invention, the pair of sub-beam portions

However, according to the present invention, the object to be suspended (distorted)
It is not. According to the invention of claim 3, claim 1
Alternatively, the hanging device according to the second aspect further includes a detecting unit that detects an inclination of the upper surface of the suspended object lifted by the crane with respect to the reference surface. Therefore, by mounting the detecting means on the upper surface of the suspended object in advance and then lifting the same, the inclination of the upper surface of the suspended object with respect to the reference plane is automatically detected. The described adjusting means or the main adjusting means and the pair of sub adjusting means described in claim 2 perform the adjusting operation.

According to the present invention described in claim 4, according to claim 1 of the present invention,
Using the hanging device according to any one of claims 3 to 3,
The unit for housing configuration is placed on the top surface of the foundation or the top surface of the unit for housing configuration. Therefore, when a unit for housing configuration having a nonuniform load distribution is lifted by a crane, the upper surface of the unit can be reliably leveled. Then, in this state, the unit for housing configuration is mounted on the upper surface of the foundation or the upper surface of the unit for housing configuration, so that there is no need to perform fine adjustment for eliminating the inclination of the unit immediately before mounting. For this reason, the mounting operation of the unit for housing configuration is facilitated, and the operation time is shortened.

Further, some of the units for housing configuration include:
For example, there is a unit such as a roof unit that is installed with the upper surface inclined at a predetermined angle with respect to the horizontal plane,
When such a unit is lifted, the reference plane may be set to a plane inclined by the roof slope with respect to the horizontal plane. If the reference surface is set and lifted in this way, the unit can be lifted with the roof surface (upper surface) inclined by the roof slope. Further, among units for housing configuration, for example, a kitchen unit is provided near a wall, such as a kitchen unit, and the center of gravity is extremely deviated. Claim 3 which referred to the hanging tool described in 2 or these claims
In the lifting device described in the above, since the adjustment by the adjusting means is performed along the longitudinal direction of the beam portion, such a kitchen unit or the like in which the position of the center of gravity is extremely deviated can be lifted in a stable state. it can.

These hooks 64 and 66 are connected to locking fittings 68 provided at four corners of the upper end face of the unit 12 by wires 70. As a result, the unit 12 is lifted by the crane at the four points via the lifting device 10.

On the other hand, a sensor box 72 is placed on the front side of the upper surface of the unit 12 in FIG. The sensor box 72 is connected to the motor 50 of the support section 22 of the main hanging device 14 via a cable 74.

Hereinafter, the operation of the present embodiment will be described through the description of the process of mounting the unit 12 on the foundation 106 (shown in FIG. 10) while lifting the unit 12 from the carrier of a transport vehicle (not shown) with a crane.

First, the unit 12 and the crane wire 3
8 and the hook 40 are connected by the hanging tool 10. As an example of the procedure, the hook 40 of the wire 38 of the crane is locked to the locking portion 34 of the support portion 22 of the main hanging device 14. At this time, the sensor box 72 for the main hanging device 14 is placed at a predetermined location on the upper surface of the unit 12 (the center on the near side in FIG. 1) by using the magnetic force of the magnet 86. Next, the beam portion 20 of the main hanging
The support portion 60 of the left sub-hanging device 16 is locked to the left hook 26, and the support portion 62 of the right sub-hanging device 18 is locked to the right hook 26. At this time, the sensor boxes 76 and 80 for the sub-hangers 16 and 18 are placed at predetermined locations on the upper surface of the unit 12 (the left center and the right center in FIG. 1) in the same manner as described above. Then
The hooks 64, 66 of these sub-hangers 16, 18 are connected to the locking metal fittings 68 at the four upper corners of the unit 12 by wires 70. Thus, the operation before the lifting operation of the crane is completed.

Next, the unit 12 is actually lifted by operating the crane. Here, since the load distribution of the unit 12 is generally uneven, even if it is lifted as it is in the state shown in FIG. 1, the upper surface of the unit 12 cannot be kept horizontal. Accordingly, the upper surface of the unit 12 is inclined at a predetermined angle with respect to the horizontal plane. In this case, the following adjustment operation is automatically performed.

For example, as shown in FIG.
2, the load distribution at the four corners is 500 [k
g], 700 kg at point B and 80 kg at point C
0 kg, and 600 kg at point D. When the position of the support portion 22 of the main hanging device 14 of the hanging device 10 and the positions of the supporting portions 60 and 62 of the sub hanging devices 16 and 18 are set as shown in FIG. The positions of the parts 22, 60, 62 are changed as follows.

First, focusing on the system of the left sub-suspension tool 16, a load of 500 [kg] acts on the point A and 70
Since a load of 0 [kg] is acting, unit 1
2 is inclined to the point B side. Accordingly, the sensor box 76 for the left sub-hanger 16 is also tilted correspondingly, and one of the limit switches 94 in the sensor box 76 is turned on. Note that the other limit switch 96 is off. Therefore, as can be seen from the circuit diagram shown in FIG.
In this case, the first terminal 94A and the common terminal 94C are conducted,
In the other limit switch 96, the second terminal 96B and the common terminal 96C are conducted. Thereby, the battery 1
02 from the positive terminal 1 of the battery 102.
02A to the first terminal 94 of one of the limit switches 94
Relay & timer circuit 10 through A and common terminal 94C
4. After the motor 50 is energized via the
The other limit switch 9 via the timer circuit 104
6 through the common terminal 96C and the second terminal 96B, and flows to the minus terminal 102B of the battery 102.

A predetermined blanking period is provided by the timer circuit, and only when one of the limit switches 94 (or the limit switch 96) is ON when the blanking period has elapsed, the relay is activated. It is to be excited.

As described above, when the drive current from the battery 102 is supplied to the motor 50, the motor 50 rotates forward. Therefore, the worm 5 of the output shaft 52 of the motor 50
4 rotates the helical gear 48. Therefore, the screw shaft 28 moves in the axial direction (the direction of the arrow L in FIG. 9). Relatively, the support part 60 is the beam part 5
6 has moved in the direction opposite to the arrow L direction. The coordinate y ₁ after the movement of the support portion 60 is calculated by the following equation to determine the center of gravity.

Y ₁ = Y ₁ − {A / (A + B)} × Y ₁ ... G _{1 When the} support portion 60 reaches the G ₁ position in this way, the pendulum 98 in the sensor box 76 is moved to the limit switch 9.
4 and 96 are in a non-contact state. Therefore, the energized state of the motor 50 is released, and the balancing condition of the left sub-suspension member 16 is satisfied.

Similarly, paying attention to the system of the right sub-hanger 18, a load of 800 kg is applied to the point C and a load of 600 kg is applied to the point D. Is inclined to the point C side. For this reason, the sensor box 80 for the sub-hanger 16 on the right side also inclines accordingly, and one limit switch 94 in the sensor box 80 is turned on. Note that the other limit switch 96 is off. Therefore, by the same operation as described above, the beam portion 58 moves in the direction of the arrow M in FIG. 9 (reverse relationship to the case of the above-described left sub-suspension member 16). Note that the coordinate y after the movement of the support portion 62 is obtained.
₂ is calculated by the following equation for calculating the center of gravity.

Y ₂ = Y ₂ − {C / (C + D)} × Y ₂ ... G _{2 In} this embodiment, Y ₂ = Y ₁ .

[0046] In this manner, when the support portion 62 to the G ₂ position is reached, the pendulum 98 in the sensor box 80 is in a state of non-contact with a pair of limit switches 94 and 96. Thus, the energization state of the motor 50 is released, and the balancing condition of the right sub-suspension member 18 is satisfied.

Subsequently, the adjustment of the main suspension 14 is performed. That is, in the state after the adjustment of both the sub-hanger 16, the G ₁ point of the main hanger 14 (50
0 + 700) [kg] is applied and G ₂
This means that a load of (800 + 600) [kg] is acting on the point. Therefore, it becomes possible towards the G ₂ points side is heavy, the upper surface of the unit 12 will be inclined to the G ₂ side. Therefore, one limit switch 94 is turned ON by the pendulum 98 in the sensor box 72, and the motor 50 is rotated. Accordingly, the beam unit 20 moves in the direction of arrow N in FIG. Note that the coordinate x after the movement of the support unit 22 is
It is calculated by the following equation for calculating the center of gravity.

X = X − {(A + B) / (A + B + C + D)} × X... G In the state where the above-described adjustment operations of the support portions 22, 60 and 62 are performed, the upper surface of the unit 12 is horizontal. . The position adjustment of the support portion 60 of the left sub-hanging device 16, the position adjustment of the support portion 62 of the right sub-hanging device 18, the main hanging device 1
In the process of sequentially adjusting the position of the supporting portion 22 of FIG. 4, if the center of gravity G ₁ , G ₂ , G _3, or the like is shifted, the same operation is repeatedly performed to converge and the difference is reduced. Disappears.

The unit 12 whose upper surface has been leveled by the above-described operation is placed at a predetermined position on the upper surface of the foundation 106 at the building site as shown in FIG. If the suspended unit 12 is for a two-story configuration, the unit 12 is placed on the upper surface of the unit 12 already placed on the upper surface of the foundation 106.

As described above, in the present embodiment, the sensor boxes 72, 7 for detecting the presence or absence of inclination of the upper surface with respect to the horizontal plane are described.
6 and 80 are directly mounted on the upper surface of the unit 12, and the positions of the respective supporting portions 22, 60 and 62 are changed by rotating the respective motors 50 forward or backward based on the detection result, thereby obtaining the overall center of gravity position. Since the unit 12 is configured to be lifted at G, the upper surface of a suspended object having a nonuniform load distribution, for example, the unit 12 for housing configuration as in the present embodiment, can always be kept horizontal in the lifted state. it can. Therefore, it is possible to stabilize the suspended state of the unit 12 and to improve safety.

Further, since the upper surface of the unit 12 in the suspended state can always be horizontal, the mounting of the unit 12 on the upper surface of the base 106 or on the upper surface of the unit 12 already mounted on the upper surface of the base 106 The operation can be performed without fine adjustment. For this reason, the working time can be reduced.

In this embodiment, the unit 12 can be lifted not only with the upper surface thereof being horizontal, but also with the upper surface of the unit 12 inclined at a predetermined angle. For example, since the roof unit has a roof slope, it is preferable in the later work to suspend the roof unit by inclining the upper surface by an angle matching the roof slope. In this case, the sensor case 84 itself is mounted on the roof surface as it is, and the limit switches 94, 96
By changing the arrangement position of the roof unit, it is possible to lift the roof unit in a state where the upper surface of the roof unit is inclined by the roof slope. The same effect can be obtained even if the bottom portion 84A of the sensor case 84 is configured to be rotatable with respect to the rising portion 84B.

In this embodiment, each sensor box 7
A pair of limit switches 94, 96 within 2, 76, 80
And a pendulum 98, these limit switches 9
The presence or absence of the inclination of the upper surface of the unit 12 is detected by ON and OFF of 4, 96. However, the present invention is not limited to this. A plurality of photosensors are arranged at predetermined intervals along the swing direction of the pendulum 98, Unit 12 depending on the number of sensors
May be detected with respect to the horizontal plane of the upper surface, or the inclination angle may be detected using an encoder or the like.
