[0002] Elevator rollers are frequently used in the entire elevator system. The elevator guide shoe wheel / guide shoe roller / high-speed roller guide shoe is an important component of the elevator that stabilizes the car and counterweight during the movement along the track. Its function is to keep the elevator running smoothly by rolling on the track. During the operation of the elevator, the elevator guide shoe wheel / guide shoe roller / high-speed roller guide shoe can protect the elevator track to avoid swinging or other forms of consumption. During the operation of the elevator, the elevator guide shoe wheel / guide shoe roller / high-speed roller guide shoe can convert kinetic energy into rolling friction through rolling friction when in contact with the track, thereby reducing energy loss to a certain extent.

[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 the four inner support blocks all hit 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 push the connecting rod to move upward relative to the support plate, so that the connecting rod deflects and pushes 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 toward the edge of the support cylinder, driving the lever located on the inner side to move and squeeze one end of the parallelogram block, so that the parallelogram block slides on the top surface of the inner wall of the support cylinder, and drives the second spring telescopic rod to deflect, so that 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, so that the second clamping block on the T-shaped rod deflects and separates from the second limit clamping wheel, releasing the locking state of the second clamping block on the second limit clamping wheel;

[0021] When the T-shaped rod deflects, the first spring telescopic rod deflects at the same time, and the deflected T-shaped rod is squeezed and fixed by the deflected first spring telescopic rod. At this time, the first clamping block on the T-shaped rod abuts against the first limit clamping wheel; then the counterclockwise rotation force of the bidirectional motor drives the spline spring telescopic tube and the hollow disk to rotate counterclockwise at the same time, so that the elevator wheel on the hollow disk rotates counterclockwise;

[0022] S3: During the counterclockwise rotation of the spline spring telescopic tube, the counterweight is driven to rotate and deflect to the side away from the spline spring telescopic tube, and then cooperates with the folding rod to drive the third bearing to move upward, further driving the wedge block to move upward to squeeze the T-shaped rod corresponding to it and deflect it, so that the first clamping block on one end of the T-shaped rod is separated from the second limit clamping wheel, reducing the resistance of the hollow disk during rotation; then the grinding block is driven by the driving cylinder to move and contact the surface of the elevator wheel in the rotating state, so as to grind the surface of the elevator wheel.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In the present invention, the counterclockwise rotation of the bidirectional motor drives the threaded rod to rotate counterclockwise, so that the internal threaded tube moves vertically upward on the threaded rod, thereby pushing the spline spring telescopic tube to move vertically upward, and pushing the hinged plate hinged on its inner tube to deflect, thereby making the four inner support blocks slide and expand in the rectangular limit groove, and fix the inner wall of the elevator wheel.

[0025] In the present invention, after the four inner support blocks all abut against the inner wall of the elevator wheel, the inner tube of the spline spring telescopic tube can no longer move upward, and at this time, the connecting rod on the outer tube of the spline spring telescopic tube continues to move upward, so that the spline spring telescopic tube is compressed, and 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, so that the second clamping block on the T-shaped rod deflects and separates from the second limit clamping wheel, thereby releasing the locked state of the second clamping block on the second limit clamping wheel; then, the counterclockwise rotation force of the bidirectional motor drives the spline spring telescopic tube and the hollow disk to rotate counterclockwise at the same time, so that the elevator wheel on the hollow disk rotates counterclockwise, and the grinding block cooperates 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 block is driven to rotate and deflect toward the side away from the spline spring telescopic tube, and then cooperates with the folding rod to drive the third bearing to move upward, and further drives the wedge block to move upward to squeeze the T-shaped rod corresponding to it and deflect it, so that the first clamping block on one end of the T-shaped rod is separated from the second limit clamping wheel, thereby reducing the resistance of the hollow disk during rotation.

[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 Fig. 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 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, so that the spline spring telescopic tube 5 is compressed and pushes the connecting rod 812 to move upward relative to the support plate 813, so that the connecting rod 812 deflects and pushes 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 Z-shaped plate 86 to move to the inner side of the Z-shaped plate 86. 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 supporting 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, and the second clamping block 75 releases the locking state of the second limit clamping wheel 72;

[0056] 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. 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 counterclockwise at the same time, so that the elevator wheel on the hollow disk 61 rotates counterclockwise;

[0057] S3: During the counterclockwise rotation of the spline spring telescopic tube 5, the counterweight block 94 is driven to rotate and deflect to the side away from the spline spring telescopic tube 5, and then cooperates with the folding rod 95 to drive the third bearing 96 to move upward, and further drives the wedge block 98 to move upward to squeeze the T-shaped rod 73 corresponding to it to deflect, 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, reducing the resistance of the hollow disk 61 during rotation; 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, so as to grind the surface of the elevator wheel;

[0058] S4: When the device finishes grinding the elevator wheel, the grinding block 11 is separated from the surface of the elevator wheel by contracting the driving cylinder 10, and then the rotation of the bidirectional motor 2 is stopped. At this time, the third bearing 96 moves downward under the action of the reset force of the third spring telescopic rod 97, and drives the wedge block 98 to move downward and separate from the T-shaped rod 73; at this time, the T-shaped rod 73 drives the first clamping block 74 to contact the first limit clamping wheel 71 under the action of the reset thrust of the first spring telescopic rod 76;

[0059] Then the bidirectional motor 2 is started to rotate clockwise. At this time, the first clamping block 74 restricts the first limiting clamping wheel 71, so that the hollow disk 61 cannot rotate clockwise. At this time, the internal threaded tube 4 moves downward under the clockwise rotation force of the threaded rod 3, thereby driving the connecting rod 812 to move downward relative to the support plate 813, and the connecting rod 812 moves downward to drive 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 supporting cylinder 1 to move in the direction close to the parallelogram block 82. When the lever 88 is reset and squeezed onto 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 get stuck on the second limiting clamping wheel 72, completing the reset of the T-shaped rod 73;

[0060] Then, the friction force of the second clamping block 75 deflecting and clamping on the second limit clamping wheel 72 causes the bidirectional motor 2 to continue to rotate clockwise to drive the spline spring telescopic tube 5 to move downward, thereby releasing the squeezing 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.

8. A method for using an elevator wheel surface processing device for elevator parts processing, using the elevator wheel surface processing device for elevator parts processing as claimed in any one of claims 1 to 7, 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), and abut against the inner wall of the elevator wheel to fix; 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), so that the connecting rod (812) deflects and pushes 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 Z-shaped plate (86) 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), and then cooperates with the folding rod (95) to drive the third bearing (96) to move upward, and further drives the wedge block (98) to move upward to squeeze the T-shaped rod (73) corresponding to it 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; then, the grinding block (11) is driven by the driving cylinder (10) to move and contact with the surface of the elevator wheel in the rotating state, so as to grind the surface of the elevator wheel.
