DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for lubricating between a tire inner peripheral surface constituting a slipper portion of a rotary kiln and a shell-side block in contact with the inner peripheral surface.

[0002]

2. Description of the Related Art The body of a rotary kiln is a steel cylinder which is rotatable about its axis and is slightly inclined from horizontal, and is entirely or partially lined with a refractory material. The size of the kiln is, for example, several tens of meters in length and several meters in inner diameter for cement firing. The support is provided at three to four places in the longitudinal direction. At each of the support positions, as shown in FIG. 5, a slide block 2 is provided on the outer periphery of the shell 1 of the rotary kiln body, and the inner peripheral surface is in contact with the slide block. A pair of rollers 4 provided with a tire 3 and abutting against the outer peripheral surface of the tire 3
It is supported and rotatable. Slide block 2
Are provided in the circumferential direction with a gap e therebetween.
Has a groove-like portion consisting of a surface facing the inner peripheral surface 3a of the tire 3 and a surface facing near the inner edges of both side surfaces of the tire 3. The tire 3 is a ring having a width of about 1 m, a rectangular cross section in a radial direction, an inner diameter dimension determined in consideration of thermal expansion, and opposing an inner peripheral surface of the tire and an inner peripheral surface of the slide block 2. There is some leeway between the surface. In the rotation of the rotary kiln body, slippage occurs between the slide block 2 and the tire 3, and the tire 3 also rotates. In such a rotary kiln, lubrication with oil or fat is performed between the slide block 2 and the inner peripheral surface of the tire 3.

A conventional technique of this type is disclosed in Japanese Utility Model Laid-Open No. 2-1.
No. 24492. The general configuration is such that a swingable arm is provided on a base near the rotary kiln tire, a lubricating oil injection nozzle and a roller are attached to the tip of the arm, and the roller is provided intermittently on the outer periphery of the rotary kiln shell. (Slide block)
The arm is disposed at a position where the arm comes in contact with the rotary kiln, and the intermittent swinging movement of the arm caused by the rotation of the rotary kiln is detected by a limit switch, and the solenoid valve is operated by the detection signal to control the lubricating oil injection timing. A controller is attached. The surface temperature of a rotary kiln is often several hundred degrees, and the temperature around the rotary kiln is 200 to 300 ° C. Therefore, the above-described conventional technology uses an electric component to detect the timing of lubricating oil injection. Therefore, there is a problem in heat resistance. Furthermore, since the lubricating oil injection nozzle is attached to the arm, it swings with the arm, so it is difficult to secure the optimal position of the lubricating oil injection nozzle and detect an appropriate timing with a complicated slide block shape. There was a problem that was difficult to implement.

Therefore, the applicant of the present application first provided a detector on the rotary kiln main body side to lubricate a predetermined greasing portion near the contact position between the slide block and the tire, and provided the detector on the fixed portion with the detector. A swing arm that is driven and swings is provided, and a nozzle is provided in a fixed portion connected to a shot valve that is supplied with pressurized oil and directed to a position where the predetermined greasing portion passes, and the nozzle is provided with the greasing. There has been proposed a rotary kiln slipper part greasing device (see Japanese Patent Application No. 4-278121) in which the shot valve is opened by a cam provided on the swing arm during a period in which the shot valve is opposed to the part. This rotary kiln slipper unit lubrication device is a purely mechanical device that does not use any electrical components, so it has high heat resistance, has less trouble due to heat, and has a detector and a swing block with a swing arm and cam mechanism. Even if the shape of the oil is complicated, it is possible to secure an appropriate oil and fat injection timing, and it is possible to surely supply oil to the oil supply part by fixing the nozzle.

[0005]

SUMMARY OF THE INVENTION However, the above-mentioned proposal has a problem in that a portable greasing apparatus is provided which sequentially grates a number of greasing positions of a predetermined rotary kiln. At each greasing position, it is necessary to install a nozzle provided on the base frame and a swing arm provided with a shot valve and a cam attached to the nozzle at an appropriate position. The installation depends on the operator, but under high temperature, it is necessary to fix the base frame as an accurate position instantaneously so that the tip of the swinging arm is located within the turning trajectory of the detecting object during turning. The problem is that the work is quite difficult. In addition, the slipper unit lubrication device proposed above only lubricates between the groove bottom of the slide block and the tire peripheral surface, but lubrication is also required between the groove side surface and the tire side surface. Currently, the tire is manually applied to the side of the tire with a brush. If the nozzle angle can be slightly changed, the same greasing device can be used for greasing the portion, but the operation is difficult with the conventional device. In addition, the greasing of one tire needs to be performed separately from both sides of the tire, and the jetting direction of the nozzle needs to be different depending on the greasing position. In this case, there is a problem that two devices are required. The present invention has been made in view of the above problems, and has an object to provide a rotary kiln slipper greasing device that can operate a greasing device installed on a base frame at a position as far away from a rotary kiln as possible and can be accurately installed in a short time.

9, a member 86, a grip portion 81, and the like are integrated, and can be rotated by 90 ° around a shaft 80. The illustrated state is a state where the inner cylinder 72 has been turned upright, and the inner cylinder 72 is upright, and the member 79 is horizontal. In the drawing , reference numeral 90 denotes a stopper, and the member 79 comes into contact with the stopper when it is rotated downward as indicated by the imaginary line.

The displacement mechanism 72 includes an outer cylinder 74 made of a pipe material slidably fitted to the inner cylinder 75, and a fulcrum portion provided in the middle of the member 79. Are connected to an end of the outer cylinder 74 on the shaft 80 side by a shaft 83 and the other end is a lever 71 having an operation unit, a mounting table 70 connected to the other end of the outer cylinder 74, and the like. In the outer cylinder 74, two upward projections 76 are provided on the substrate 84 side near the upper end in the drawing, projecting slightly away from the surface of the outer cylinder in parallel with the outer cylinder. The member provided with the hole 77 is fixed. The displacement mechanism 72 can be operated by dimensions x's only linear displacement in the axial direction of the outer cylinder 74 relative to the inner cylinder 75 with the lever 71. Also, the lever 71 is shown in FIG.

The two support pins 73 abutting on 4 are fixed. The support pins 73 correspond to the two mounting holes 24 of the base frame 20 and have an outer diameter that fits into the holes at the same pitch as the pitch of the mounting holes 24. The pin 73 is positioned on the mounting table 70 by the positioning member 20a welded to the substrate 84 with the hole 24 fitted. The position of the swing arm 12 with respect to the detector 11 of the rotary kiln, the nozzle 1
The injection direction of No. 5 is appropriately determined, and a greasing device is mounted. As shown in FIGS. 1 and 2, the direction in which the nozzle 15 is directed is such that the detection body 11 rotates in the kiln rotation direction and starts to contact the roller 22 of the swing arm 12 at the initial position regulated by the stopper 18. At this time, the slide block 2 is adjusted so as to be located at the rear end in the rotation direction of the slide block 2 toward the start end of the greasing portion between the outer peripheral surface of the rotary kiln body 1 and the inner peripheral surface of the tire 3. At this time, the operation arm 55 is engaged with the first engagement position of the block 54. Then, when the rotation of the kiln advances a little and the detection body 11 reaches the position shown by the solid line in FIG. 2, that is, when the swing arm 12 slightly swings from the initial position,
The roller 43 is adjusted so as to start riding on the convex portion 42 of the cam, and so that the roller 43 comes off from the convex portion 42 of the cam before the position where the nozzle 15 faces is the terminal position in the rotation direction of the greasing portion. It is.

The lubricating apparatus shown in FIGS. 1 and 2 is designed to inject and supply oil from one side of the side surface of the tire 3, and the tire 3 has a wide width. Therefore, it is necessary to inject and supply oil and fat to one tire 3 from both sides . In this case, mounted on the base frame 20 of the greasing device

This is because it is performed at a position where it is located. However, the lubrication system
The part mounted on the base frame 20 is used for the movement of the detection body 11.
Therefore, the swing arm 12 is driven in a predetermined direction.
Therefore, the positional relationship is one of those shown in FIG.
The part mounted on the base frame 20 of the greasing device
It is necessary to have the positional relationship shifted to the right
You. In this positional relationship, the opposite side of the tire 3
Mounted on the base frame 20 of the greasing device on the mounting jig 16 (not shown)
When the part that has been
Since the pin 73 is fitted from the opposite side,
Is supported, but the jet direction of the nozzle is the tire 3
The direction is opposite to the direction. In other words, the jet direction of the nozzle
The greasing device is installed on the opposite side
When replace the ingredients 16, engaged with the groove of the opposite side of the block 57 by operating the operation arm 55 to the injection direction opposite to.

As a device for pressurizing and supplying oil and fat to a greasing hose connected to the shot valve 13, a portable device including a known air grease pump using compressed air, a grease tank, an accumulator and the like is used.

The lubricating apparatus thus constructed is provided with a base frame 2
0 is attached to the mounting base 70 of the mounting jig 16 using the mounting hole 24 and used. This mounting operation is performed at the attachment / detachment position where the lever 71 and the member 79 rotate downward and come into contact with the stopper 87 as shown by a virtual line in FIG. At this attachment / detachment position, although not shown, the support pins 7
Reference numeral 3 projects upward, and an attachment hole of the base frame 20 is fitted into the projection 3. Then, the user holds the grip portion 81 and pivots upward about the swing fulcrum shaft 80 along the arrow 87 by about 90 ° to set the use approach position. At this position, the roller 22 of the swing arm 12 is approaching the trajectory of the detection body 11, but is not within the trajectory, and the rotating mechanism 69 is not locked.
Next, while observing the movement of the detection body 11 while holding the grip portion 81, the lever 71 of the displacement mechanism 72 is moved in the direction indicated by an arrow 8 in anticipation of the timing at which the detection body 11 passes over the roller 22.
8, the mounting table 70 and the base frame 2
0 is raised to the use position shown by the solid line in FIG. 1, and the lever 71 is locked by the locking metal member 82 to be in the locked state. When displaced to this use position, the engagement projection 76 enters the engagement hole 77, and the rotation mechanism 69 is locked. In the greasing device in the use position, the operation arm 55 is in the first engagement position, and the nozzle 15 is directed to a predetermined greasing portion between the slide block 2 and the tire 3. Swing arm 2
2 is driven by the detection body 11 and swings. Therefore, when the pressurized supply of the fat or oil is performed, the fat or oil is injected and supplied from the nozzle 15 to the greasing part. When the lubrication is completed, the operation arm 55 is operated to the second position to perform lubrication on the side surface of the tire 3. When the lubrication is completed, the pressurized oil supply is stopped, and the mounting jig 16 is operated to return from the use position to the attachment / detachment position through the use proximity position, and the greasing device is removed. Next, when lubricating from the opposite side of the tire 3, the direction of the nozzle 15 is reversed, and the same operation is performed as described above. In this manner, the lubrication can be performed by one greasing device using the mounting jigs 16 provided at the respective greasing positions.

In this rotary kiln slipper lubricating device, the lubricating device installed on the base frame 20 can be attached to and detached from the mounting table 70 at an attaching / detaching position sufficiently away from the rotary kiln. Since the mounting jig 16 can be operated at a position away from the rotary kiln to be in the use position, the operation of changing the nozzle 15 which needs to be closest to the rotary kiln from the first position to the second position is performed by the operation arm 55. Workability is extremely good because it is possible with simple operations. That is, it is a rotary kiln slipper lubrication device that can be installed and removed accurately in a short time. Further, since the rotary kiln slipper unit lubrication device is a purely mechanical device that does not use electric components, it has high heat resistance and is less likely to be damaged by heat. Further, even if the shape of the slide block 2 is complicated by the swing arm 12 and the cam mechanism, an appropriate oil / fat injection timing can be ensured by properly providing the detection body 11, and the nozzle is fixed so that the nozzle can be reliably directed to the lubrication site. it can. Therefore, it is possible to reliably and satisfactorily lubricate the lubrication site. In addition, the nozzle 15 can easily change its jetting direction between the first position and the second position by the operation arm 55, and to the position where the nozzle 15 is misaligned. Grease can also be supplied between the tire 2 and the side surface of the tire 3.
