DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for replacing an existing rope (hereinafter referred to as an "existing rope") in an elevator or the like with a new rope (hereinafter referred to as a "newly installed rope"). The present invention relates to a rope winding device suitable as a jig to be used.

2. Description of the Related Art As a conventional technique of winding a rope by driving an electric motor in this type of rope winding apparatus, for example, one disclosed in Japanese Patent Application Laid-Open No. 9-104573 is known. In this prior art, a cable is used to connect an electric motor that rotates a winding drum main body that winds a rope, and an operation device that includes a forward operation switch that drives the motor forward and a reverse operation switch that drives the motor reverse. In this configuration, "forward" is displayed on the forward switch portion, and "reverse" is displayed on the reverse operation switch portion.

[0003] In the operation of winding the rope, when an operation of rotating the winding drum main body forward and winding the rope around the winding drum main body is to be performed, the operator displays "normal" on the operating device. When the operator operates the normal rotation operation switch to reverse the winding drum main body and draw out the rope from the winding drum main body, that is, when performing the rewinding operation, the operator needs to operate the operating device in the “reverse” position.
Operate the reverse operation switch that is displayed.

[0004]

In the above-mentioned prior art, when the winding drum main body is rotated forward, the forward rotation operation switch is operated by looking at the character signs "forward" and "reverse" of the operating device. When the take-up drum body is reversed, the reverse operation switch is operated, and the electric motor, that is, the take-up drum body can be rotated without error.

[0005] However, since the operator has little experience in rope winding work, he does not seem to fully understand which of the rotation directions of the winding drum is the normal rotation and which is the reverse rotation. In some cases, for example, the rotation direction which is originally the reverse rotation direction is erroneously recognized as the normal rotation direction, and the winding drum body is rotated in the erroneously recognized reverse rotation direction,
There is a concern that an erroneous operation of operating the forward rotation operation switch may occur. If such an erroneous operation occurs, an excessive load may be applied to the winding drum main body in some cases, thereby causing damage to gears included in the transmission mechanism that transmits the rotational force, or causing the electric motor to burn out, and the like. There has been a problem that wear is caused and the life of the rope winding device is shortened.

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation in the prior art, and has as its object to provide a rotation direction of a winding drum main body and an operating device even for an inexperienced worker in rope winding work.

7b and 27c are fixed. These mounting members 2
7, 27a, 27b, 27c are arranged around the drum unit 25, for example, at equal intervals. These mounting members 2
As shown in FIGS. 8 and 9, 7, 27a, 27b, and 27c are members formed by cutting a steel pipe having a C-shaped cross section, for example, and are welded to a rope winding member 23 also made of steel. It is integrated. The outer diameter of the end 28a of the existing rope 28 formed by twisting steel wires is the same as or slightly smaller than the dimension L2 of the notch G of the mounting members 27, 27a, 27b, 27c as shown in FIG. Is set to

As shown in FIGS. 7 and 8, the end portion 28 a of the existing rope 28 is provided with a stopper member for preventing the rope 28 from coming off from the attachment member 27 when a tensile force acts on the existing rope 28, for example. A flexible binding band 29 and a binding ring 30 are mounted. The existing rope 28 is wound around the drum 25 in a state of being stored in each of the attachment members 27, 27a, 27b, and 27c, so that a corresponding portion of the existing rope 28 is attached to the attachment members 27, 27a, and 2c.

The detachment of the existing rope 28 from the notch G portion is prevented.

As shown in FIGS. 11 and 12, a U-shaped protection wall 33 is formed on the upper surface of the control box 17 to protect the connection portions of the power indicator lamp 18, the power switch 20, and the cable 19. . The height of the protection wall 33 is set to be higher than the top of the power indicator 18 and the power switch 20. For example, when the long member falls from above the control box 17, the falling of the long member may cause the protection wall 3 to fall.
Blocked at the top of 3.

The rope winding device 1 configured as described above
At the time of winding work of the existing rope 28, as shown in FIG. 5, for example, the base 2 is attached to the lashing belt 3 on the crosshead 31 arranged on the elevator car.
It is attached by fastening with 2. In this case, openings 39, 40, 41 and a notch 42 are formed in the base 2, and by passing the lashing belt 32 through these openings 39, 40, 41 and the notch 42, the base 2 is attached. It is fixed to the crosshead 31.

At this point, the existing rope 28 from which the car was suspended is cut, and the cut end 28a is fitted around the mounting member 27, 27a, 27b, 27c of the take-up drum body 4, and the cut end 28a is inserted. As shown in FIG.
9 and the binding ring 30 are attached.

In this state, the operator checks the rotation direction in which the take-up drum body 4 rotates in the normal direction with the arrow sign 102a, checks the push button switch to be operated with the character sign 103a, and uses these arrow sign 102a and the character sign. The operator pushes the pushbutton switch 101a for forward rotation of the operation device 101 which is the same blue color as the sign 103a. As a result, the electric motor 5 is driven, and the rotational force is transmitted to the winding drum main body 4 via the transmission mechanism 6.
By the rotation of the take-up drum body 4, the existing rope 28 used to suspend the car is moved to the drum portion 2 of the take-up drum body 4.
5 is wound around the gap member 34. When it is necessary to rewind the existing rope 28 during this operation, the operator confirms the rotation direction in which the winding drum main body 4 reverses with the arrow sign 102b, and sets the operated push button switch to the character sign 1.
Confirmation is made at 03b, and the pushbutton switch 101b for reverse rotation of the operation device 101 which is the same red color as the arrow sign 102b and the character sign 103b may be pressed. As a result, the electric motor 5 rotates in the reverse direction, and accordingly, the winding drum main body 4 rotates in the reverse direction, and a desired operation for rewinding the existing rope 28 is performed.

When finishing the work of winding the existing rope, the operator only needs to release the pressing force on the push button switch 101a and the like of the operating device 101. As a result, the electric motor 5 stops, and the rotation of the winding drum main body 4 stops.

Then, by opening the bearing retainer 14 shown in FIG. 1 upward, the winding drum body 4 on which the existing rope 28 is wound is manually moved from between the pair of plate-like portions 3a and 3b of the support frame 3. It can be disengaged and lifted upward.

The winding drum body 4 on which the existing rope 28 is wound as described above is transported to a predetermined work place outside the elevator, for example. At the work place, the rope winding member 24 is detached from the drum portion 25 of the rope winding member 23 by loosening the thumbscrew shown in FIG. By removing the binding ring 30, the existing rope 28 wound around the drum unit 25 can be removed from the winding drum main body 4.

According to the present embodiment configured as described above,
As described above, the winding drum main body 4 is rotated by looking at the arrow sign 102a and the character sign 103a that are the forward rotation sign and the arrow sign 102b and the character sign 103b that are the reverse rotation sign of the winding drum main body 4. You can know the direction you are going to do. When an operation of winding the existing rope 28 around the winding drum main body 4 is to be performed, the push button switch 101a of the operation device 101 may be operated by looking at the arrow mark 102a and the character mark 103a, and conversely, When the operation of unwinding the existing rope 28 from the winding drum main body 4, that is, performing the rewinding operation, is performed, the arrow sign 102 b and the character sign 103 are used.
It is sufficient to operate the push button switch 101b of the operation device 101 while looking at b. Therefore, even if the worker has little experience of winding the existing rope 28, the rotation direction of the winding drum main body 4 and the operation of the push button switch 101a, which is the operation unit for normal rotation, of the operation device 101, and the operation unit for reverse rotation. The relationship with the operation of the push button switch 101b can be correctly recognized, and an erroneous operation in which the winding direction of the winding drum body 4 is incorrect in the winding operation of the existing rope 28 can be prevented.
As a result, the first gear 8 and the second gear 10 included in the transmission mechanism 6 that transmits the rotational force to the winding drum main body 4 are damaged, and the components such as the electric motor 5 that generates the rotational force are burned. And excellent durability can be obtained.

Further, the operator can drive the electric motor 5, that is, drive the winding drum body 4 forward and backward by simply pressing the push button switches 101a and 101b of the operating device 101, and the operation is simple. Thereby, the winding operation of the existing rope 28 can be efficiently performed.

In addition, according to the present embodiment, the winding drum main body 4 around which the existing rope 28 is wound can be lifted upward from between the pair of plate-like portions 3a, 3b of the support frame 3. In addition, the take-up drum body 4 can be easily removed from the car on which a sufficient working space cannot be secured in the left-right direction, and the efficiency of the work of winding the rope 28 can be improved.

The motor 5 is provided on one of the opposed plate portions 3a of the support frame 3 so that the rotating shaft of the motor 5 extends in the vertical direction. 5 can have a compact structure that does not protrude from the width direction of the plate-shaped portion 3a of the support frame 3. In addition, since the protection frame 15 is provided around the electric motor 5, it is possible to prevent devices in the hoistway from coming into contact with the electric motor 5, thereby preventing the electric motor 5 from being damaged.

Further, since the position of the center of gravity is set to a position where the base 2 does not fall when the base 2 is placed on a flat surface, the winding operation of the rope 28 placed on a flat surface such as a car is required. It can be done easily.

The support frame 3 has a plurality of openings 3c, and the rope winding members 23, 24 are provided with openings 23a, 23c.
b, 23c, 24d, etc., and the drum portion 25 of the rope winding member 23 also has a plurality of openings 25b, so that the weight of the entire apparatus can be reduced and the handling is easy.

Further, the support frame 3 is formed by using one plate
The support frame 3 is formed by bending in the shape of a letter, and such a bending process is simpler than a combination of cutting and welding of a plate material, so that the support frame 3 can be easily manufactured and the manufacturing cost is low. I can do it. The base 2 has an opening 3
Since it has 9, 40 and 41, it contributes to weight reduction of the device. Further, since the notch 42 is provided together with the openings 39, 40, and 41, when the base 2 is fixed to the crosshead 31 on the elevator car, the lashing belt 32 can be easily attached and detached. This also contributes to improving work efficiency.

The drum portion 25 of the rope winding member 23
However, since it is formed by the gap members 34 having a large number of rod shapes, a relatively large space can be formed between the adjacent gap members 34, which also contributes to the weight reduction of the apparatus.

Also, since the first gear 8 and the transmission shaft 7 of the transmission mechanism 6 are covered by the gear cover 110, the first gear 8 and the transmission shaft 7 that are rotating when the rope 28 is wound up. It is possible to prevent accidents in which the workers come into contact with each other, and to ensure work safety.

Since the reinforcing plate 105 for connecting the opposed plate-like portions 3a and 3b of the support frame 3 is provided,
