Description

Technical Field

[0001] The present invention relates to the field of elevator wheel processing, and specifically to a surface processing device and a usage method for elevator wheels used in elevator accessory processing. Background Technique

[0002] Elevator rollers are used very frequently in the entire elevator system. Elevator guide shoe wheels / guide shoe rollers / high-speed roller guide shoes are important components that play a role in stabilizing the car and counterweight during the movement of the elevator along the track. Their function is to keep the elevator running smoothly by rolling on the track. During the operation of the elevator, the elevator guide shoe wheels / guide shoe rollers / high-speed roller guide shoes can protect the elevator track to avoid swinging or other forms of consumption. During the operation of the elevator, the elevator guide shoe wheels / guide shoe rollers / high-speed roller guide shoes can convert kinetic energy into rolling friction when contacting the track, thereby playing a role in reducing a certain amount of energy loss.

[0003] After turning the elevator traction wheel, there will be metal residues such as burrs and sharp corners at its edge. This metal residue will pose a safety impact on the operator and will cut the rope, affecting the service life of the rope. Therefore, it is necessary to polish the surface of the elevator traction wheel; when the existing device polishes the elevator traction wheel, it is necessary to first fix the inner wall of the elevator traction wheel through a fixture, and then drive the fixture holding the elevator traction wheel to rotate through a motor, cooperate with the polishing block to polish the elevator traction wheel, and then remove the polished elevator traction wheel from the fixture, resulting in a relatively cumbersome process for the device to process the surface of the elevator traction wheel, affecting the processing efficiency of the device for the elevator traction wheel.

A reset spring telescopic rod is fixedly connected to the shift lever, and the upper end of the reset spring telescopic rod is fixedly connected to the bottom surface of the Z-shaped plate;

[0012] Two support plates are provided on both sides of the push block for limited sliding. Second bearings are fixed on one end of the two support plates away from the push block, and the second bearings are fixedly sleeved on the inner tube of the spline spring telescopic tube.

[0016] Preferably, the limiting sliding groove is perpendicular to the rectangular through groove.

[0017] Preferably, the upper end surface of the lever is an isosceles right triangle, and the two levers are distributed on both sides of the corresponding parallelogram block.

[0018] Preferably, the method for using the elevator wheel surface processing device for elevator parts processing comprises the following steps:

[0019] S1: When the device processes the elevator wheel, the elevator wheel to be processed is firstly sleeved on the outside of the four inner support blocks, and then the bidirectional motor rotates counterclockwise to drive the threaded rod to rotate counterclockwise, so that the inner threaded tube moves vertically upward on the threaded rod, and then pushes the spline spring telescopic tube to move vertically upward, and pushes the hinged plate hinged on its inner tube to deflect, so that the four inner support blocks slide and expand in the rectangular limit groove, and resist and fix the inner wall of the elevator wheel;

[0020] S2: When all four inner support blocks are in contact with the inner wall of the elevator wheel, the inner tube of the spline spring telescopic tube can no longer move upward. At this time, the connecting rod on the outer tube of the spline spring telescopic tube continues to move upward, causing the spline spring telescopic tube to compress, and pushing the connecting rod to move upward relative to the support plate, causing the connecting rod to deflect and push the push block to slide between the two support plates, thereby driving the Z-shaped plate on the upper side of the push block to move towards the edge of the support cylinder, driving the inner lever to move and squeeze one end of the parallelogram block, causing the parallelogram block to slide on the top surface of the inner wall of the support cylinder, and driving the second spring telescopic rod to deflect, causing the two cylinders on the parallelogram block to slide in the rectangular through slot and squeeze one end of the T-shaped rod to deflect clockwise, causing the second locking block on the T-shaped rod to deflect and separate from the second limiting camming wheel, releasing the locked and jammed state of the second locking block on the second limiting camming wheel;

[0021] And when the T-shaped rod deflects, the first spring telescopic rod deflects simultaneously, and the deflected first spring telescopic rod squeezes and fixes the deflected T-shaped rod. At this time, the first locking block on the T-shaped rod abuts against the first limiting camming wheel; then, the reverse rotational force of the bidirectional motor drives the spline spring telescopic tube and the hollow disk to rotate counterclockwise simultaneously, prompting the elevator wheel on the hollow disk to rotate counterclockwise;

[0022] S3: And during the counterclockwise rotation of the spline spring telescopic tube, it drives the counterweight to rotate and deflect towards the side away from the spline spring telescopic tube, thereby cooperating with the folding rod to drive the third bearing to move upward, further driving the wedge block to move upward and squeeze the corresponding T-shaped rod to deflect, causing the first locking block at one end of the T-shaped rod to separate from the second limiting camming wheel, reducing the resistance during the rotation of the hollow disk; then, the driving cylinder drives the grinding block to move into contact with the surface of the rotating elevator wheel to grind the surface of the elevator wheel.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In the present invention, the counterclockwise rotation of the bidirectional motor drives the threaded rod to rotate counterclockwise, causing the internally threaded tube to move vertically upward on the threaded rod, thereby pushing the spline spring telescopic tube to move vertically upward, and pushing the hinge plate hinged on its inner tube to deflect, thereby causing the four inner support blocks to slide and expand in the rectangular limiting slot to abut and fix the inner wall of the elevator wheel.

[0025] In the present invention, after all four inner support blocks are in contact with the inner wall of the elevator wheel, the inner tube of the spline spring telescopic tube can no longer move upward. At this time, the connecting rod on the outer tube of the spline spring telescopic tube continues to move upward, causing the spline spring telescopic tube to be compressed. Then, the two cylinders on the parallelogram block slide in the rectangular through groove and squeeze one end of the T-shaped rod to deflect clockwise, causing the second locking block on the T-shaped rod to deflect and separate from the second limit locking wheel, releasing the locked and jammed state of the second locking block on the second limit locking wheel. Then, the reverse rotational force of the bidirectional motor drives the spline spring telescopic tube and the hollow disk to rotate counterclockwise simultaneously, prompting the elevator wheel on the hollow disk to rotate counterclockwise, and cooperating with the grinding block to grind the surface of the elevator wheel.

[0026] In the present invention, during the counterclockwise rotation of the spline spring telescopic tube, the counterweight is driven to rotate and deflect away from the spline spring telescopic tube. Furthermore, in cooperation with the folding rod, the third bearing is driven to move upward, further driving the wedge block to move upward and squeeze the corresponding T-shaped rod to deflect, causing the first locking block at one end of the T-shaped rod to separate from the second limit locking wheel, reducing the resistance during the rotation of the hollow disk.

[0051] In this embodiment, Figure 4 , Figure 6 , Figure 8 As shown, the upper end surface of the lever 88 is an isosceles right triangle, and two levers 88 are distributed on both sides of the corresponding parallelogram block 82 .

[0052] The use method and advantages of the present invention: The use method of the elevator wheel surface processing device for elevator parts processing, the working process is as follows:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown:

[0054] S1: When the device processes the elevator wheel, the elevator wheel to be processed is firstly sleeved on the outer side of the four inner support blocks 63, and then the bidirectional motor 2 rotates counterclockwise to drive the threaded rod 3 to rotate counterclockwise, so that the inner threaded tube 4 moves vertically upward on the threaded rod 3, thereby pushing the spline spring telescopic tube 5 to move vertically upward, and pushing the hinged plate 64 hinged on its inner tube to deflect, thereby making the four inner support blocks 63 slide and expand in the rectangular limit groove 62, and resist and fix the inner wall of the elevator wheel;

[0055] S2: When all four inner support blocks 63 are in contact with the inner wall of the elevator wheel, the inner tube of the spline spring telescopic tube 5 can no longer move upward. At this time, the connecting rod 812 on the outer tube of the spline spring telescopic tube 5 continues to move upward, causing the spline spring telescopic tube 5 to compress. The connecting rod 812 is pushed to move upward relative to the support plate 813, causing the connecting rod 812 to deflect and push the push block 85 to slide between the two support plates 813. Furthermore, it drives the Z-shaped plate 86 on the upper side of the push block 85 to move towards the edge of the support cylinder 1, drives the inner lever 88 to move and squeeze one end of the parallelogram block 82, causing the parallelogram block 82 to slide on the top surface of the inner wall of the support cylinder 1, and drives the second spring telescopic rod 81 to deflect. The two cylinders 83 on the parallelogram block 82 slide in the rectangular through groove 84 and squeeze one end of the T-shaped rod 73 to deflect clockwise, causing the second locking block 75 on the T-shaped rod 73 to deflect and separate from the second limit locking wheel 72, releasing the locked and stuck state of the second locking block 75 on the second limit locking wheel 72;

[0056] When the T-shaped rod 73 deflects, the first spring telescopic rod 76 deflects simultaneously. The deflected first spring telescopic rod 76 squeezes and fixes the deflected T-shaped rod 73. At this time, the first locking block 74 on the T-shaped rod 73 abuts against the first limit locking wheel 71; Then, the reverse rotation force of the bidirectional motor 2 drives the spline spring telescopic tube 5 and the hollow disk 61 to rotate counterclockwise simultaneously, prompting the elevator wheel on the hollow disk 61 to rotate counterclockwise;

[0057] S3: During the counterclockwise rotation of the spline spring telescopic tube 5, it drives the counterweight 94 to rotate and deflect towards the side away from the spline spring telescopic tube 5. Furthermore, it cooperates with the folding rod 95 to drive the third bearing 96 to move upward, further driving the wedge-shaped block 98 to move upward and squeeze the corresponding T-shaped rod 73 to deflect, causing the first locking block 74 at one end of the T-shaped rod 73 to separate from the second limit locking wheel 72, reducing the resistance when the hollow disk 61 rotates; Then, the driving cylinder 10 drives the grinding block 11 to move into contact with the surface of the rotating elevator wheel to grind the surface of the elevator wheel;

[0058] S4: When the device finishes grinding the elevator wheel, the driving cylinder 10 contracts to drive the grinding block 11 to separate from the surface of the elevator wheel. Then, the bidirectional motor 2 stops rotating. At this time, the third bearing 96 moves downward under the restoring force of the third spring telescopic rod 97 and drives the wedge-shaped block 98 to move downward and separate from the T-shaped rod 73; At this time, the T-shaped rod 73 drives the first locking block 74 to abut against the first limit locking wheel 71 under the restoring thrust of the first spring telescopic rod 76;

[0059] Then start the bidirectional motor 2 to rotate it clockwise. At this time, due to the restriction of the first clamping block 74 on the first limiting clamping wheel 71, the hollow disc 61 cannot rotate clockwise. At this time, the internal thread tube 4 moves downward under the action of the clockwise rotating force of the threaded rod 3, thereby driving the connecting rod 812 to move downward relative to the support plate 813. And the downward movement of the connecting rod 812 drives the push block 85 to slide and reset on the two support plates 813, thereby driving the lever 88 on the Z-shaped plate 86 close to the edge of the support cylinder 1 to move in the direction close to the parallelogram block 82. When the lever 88 is reset and presses against the inclined surface of the parallelogram block 82, the two cylinders 83 on the parallelogram block 82 slide in the rectangular through groove 84 and squeeze one end of the T-shaped rod 73 to deflect it counterclockwise. At this time, the deflection of the T-shaped rod 73 drives the second clamping block 75 to deflect and latch on the second limiting clamping wheel 72, completing the reset of the T-shaped rod 73;

[0060] Then, due to the friction force of the second clamping block 75 deflecting and latching on the second limiting clamping wheel 72, the bidirectional motor 2 continues to rotate clockwise to drive the spline spring telescopic tube 5 to move downward, releasing the extrusion state of the four inner support blocks 63 on the inner wall of the elevator wheel, and completing the processing of the elevator wheel surface.

6. A method of using a surface processing device for an elevator wheel in elevator accessory processing, which uses a surface processing device for an elevator wheel in elevator accessory processing as described in any one of claims 1-5, characterized in that, The steps include: S1: When the device processes the elevator wheel, the elevator wheel to be processed is first placed on the outside of the four inner support blocks (63), and then the bidirectional motor (2) rotates counterclockwise to drive the threaded rod (3) to rotate counterclockwise, so that the inner threaded tube (4) moves vertically upward on the threaded rod (3), thereby pushing the spline spring telescopic tube (5) to move vertically upward, and pushing the hinged plate (64) hinged on its inner tube to deflect, thereby making the four inner support blocks (63) slide and expand in the rectangular limit groove (62), thereby contacting and fixing the inner wall of the elevator wheel; S2: When the four inner support blocks (63) all contact the inner wall of the elevator wheel, the inner tube of the spline spring telescopic tube (5) can no longer move upward. At this time, the connecting rod (812) on the outer tube of the spline spring telescopic tube (5) continues to move upward, causing the spline spring telescopic tube (5) to be compressed and pushing the connecting rod (812) to move upward relative to the support plate (813), causing the connecting rod (812) to deflect and push the push block (85) to slide between the two support plates (813), thereby driving the Z-shaped plate (86) on the upper side of the push block (85) to move toward the edge of the support cylinder (1), driving the inner side of the push block (85) to move upward. The lever (88) moves and squeezes one end of the parallelogram block (82), so that the parallelogram block (82) slides on the top surface of the inner wall of the support cylinder (1), and drives the second spring telescopic rod (81) to deflect, so that the two cylinders (83) on the parallelogram block (82) slide in the rectangular through groove (84) and squeeze one end of the T-shaped rod (73) to deflect clockwise, so that the second clamping block (75) on the T-shaped rod (73) deflects and separates from the second limit clamping wheel (72), thereby releasing the locking state of the second clamping block (75) on the second limit clamping wheel (72); When the T-shaped rod (73) deflects, the first spring telescopic rod (76) deflects at the same time, and the deflected T-shaped rod (73) is squeezed and fixed by the deflected first spring telescopic rod (76), and at this time, the first clamping block (74) on the T-shaped rod (73) abuts against the first limit clamping wheel (71); then, the counterclockwise rotation force of the bidirectional motor (2) drives the spline spring telescopic tube (5) and the hollow disk (61) to rotate in the opposite direction at the same time, so that the elevator wheel on the hollow disk (61) rotates in the opposite direction; S3: During the counterclockwise rotation of the spline spring telescopic tube (5), the counterweight (94) is driven to rotate and deflect toward the side away from the spline spring telescopic tube (5), thereby cooperating with the folding rod (95) to drive the third bearing (96) to move upward, further driving the wedge block (98) to move upward to squeeze the T-shaped rod (73) corresponding thereto and deflect it, so that the first clamping block (74) on one end of the T-shaped rod (73) is separated from the second limit clamping wheel (72), thereby reducing the resistance of the hollow disk (61) during rotation; and then the grinding block (11) is driven by the driving cylinder (10) to move and contact the surface of the elevator wheel in the rotating state, thereby grinding the surface of the elevator wheel.
