Technical Field

[0001] The utility model relates to the technical field of guide shoes, in particular to a wear-resistant rolling guide shoe. Background Art

[0002] The guide shoe is an extremely important component installed on the elevator. Its function is to ensure that the elevator runs up and down along the guide rail accurately, and to ensure the stability, comfort and safety of the elevator operation. The rolling guide shoe is generally clamped on the track with three rollers. It is generally used for elevators with speeds above two meters. The characteristic is that rolling friction replaces sliding friction, which reduces friction loss, reduces vibration and noise during operation, and improves riding comfort.

[0003] The existing patent (Announcement No.: CN206375529U) discloses an elevator rolling guide shoe, two sets of support shafts are welded on the guide shoe seat plate, two sets of rollers are fixed on the support shafts with hexagonal bolts, and the shoe lining is fixed to the middle of the two sets of rollers on the guide shoe seat plate with cross-slot countersunk screws. When the guide shoe is running, both sides of the guide rail are rollers, which has a lower friction coefficient, longer life, and better shock absorption performance. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved: the above device reduces the resistance generated by friction by setting rollers, but the guide wheel is fixed on the guide shoe seat, which makes it inconvenient to adjust the spacing between the guide wheels, which leads to inconvenience in installing the guide shoe when the width of the guide rail does not match the spacing of the guide wheels. Utility Model Content

[0004] In order to improve the above-mentioned problem of reducing the resistance generated by friction by setting rollers, but the guide wheels are fixed on the guide shoe seats, which makes it inconvenient to adjust the spacing between the guide wheels, and further leads to the problem that when the width of the guide rail does not match the spacing of the guide wheels, it is inconvenient to install the guide shoes. The utility model provides a wear-resistant rolling guide shoe.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] The T-shaped rod drives the rotating frame to rotate from a vertical position to a horizontal position, thereby releasing the fixation of the T-shaped rod and the side wheels. Then, the two side wheels are driven to move to a suitable spacing through the two T-shaped rods, and the rotating frame and the T-shaped block are driven to rotate through the T-shaped rod, so that the T-shaped block moves into the slot through the compression spring, thereby quickly fixing the adjusted side wheels.

[0022] By using polyurethane materials for the front wheels and side wheels, they have a long service life, are wear-resistant, are not easily contaminated, and have good wear resistance. Fixed bearings are placed inside the front wheels and side wheels to reduce the resistance generated when the front wheels and side wheels rotate. This can greatly reduce damage to the elevator steel cable and increase the wear resistance of the front wheels and side wheels. BRIEF DESCRIPTION OF THE DRAWINGS

The limiting block 302 can limit the C-shaped block 301 so that the limiting block can slide vertically inside the chute 5.

[0032] Refer to the accompanying drawings of the specification Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 .

The side of the rotating frame 305 is slidably connected to the inside of the adjusting slot 101, and the limiter 306 includes a T-shaped block 307, and the number of the T-shaped blocks 307 is four. Two of the four T-shaped blocks 307 are slidably connected to the inside of the rotating frame 305, and the side of the horizontal block of the T-shaped block 307 is fixedly connected with a compression spring 308, and one end of the compression spring 308 is fixedly connected to the inside of the rotating frame 305. By moving the T-shaped block 307 to the inside of the slot 102 at different positions, it is convenient to adjust the spacing between the two side wheels 4.

[0037] Working principle: When using the wear-resistant rolling guide shoe, firstly, the rotating frame 305 is driven to rotate by the T-bar 304, so that the rotating frame 305 drives two T-blocks 307 in a group from a vertical placement to a horizontal placement state, thereby releasing the fixation of the T-bar 304 and the side wheel 4, and then the two side wheels 4 are driven to move to the appropriate spacing on both sides by the two T-bars 304 according to the width of the slide rail, and then the T-bar 304 is rotated, so that the T-bar 304 drives the rotating frame 305 and the T-block 307 to rotate, and when the T-block 307 rotates to contact the inside of the adjustment slot 101, the T-block 307 moves toward the inside of the rotating frame 305 through the pressure generated by the contact with the adjustment slot 101, and squeezes the compression spring 308, and when the rotating frame 305 rotates to a vertical state, the T-block 307 moves to the inside of the slot 102 through the rebound force of the compression spring 308, thereby quickly fixing the adjusted side wheel 4.

[0038] The front wheel 2 and the side wheel 4 are made of polyurethane, which have a long service life, strong wear resistance, and are not easily contaminated. They also have good wear resistance. Bearings are fixed inside the front wheel 2 and the side wheel 4 to reduce the resistance generated when the front wheel 2 and the side wheel 4 rotate. This can greatly reduce damage to the elevator steel cable and increase the wear resistance of the front wheel 2 and the side wheel 4.

[0039] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
