Description

Technical Field

[0001] This utility model belongs to the field of elevator guide wheel technology, and in particular relates to an elevator guide wheel assembly. Background Technology

[0002] According to the published patent CN220115939U, a guide wheel assembly and a guide wheel frame are provided. A fixed leg is provided, and a fixed plate is installed on the side of the fixed leg by welding. Four fixed bolts are installed on the fixed plate. Guide wheels are installed at the upper and lower ends of the right side of the fixed leg by bolts and bearings. By providing a fixed leg, a fixed plate, guide wheels and pulleys, the platform and the lifting equipment can be properly connected by the fixed leg, so that the lifting platform can drive the platform to move up and down. However, the following shortcomings still exist.

[0003] The aforementioned equipment has the problem that the spacing and position of the guide wheels are relatively fixed during use. This may not be conducive to sliding when facing different types of lifting platform guide rails, which in turn makes it difficult for the equipment to maintain a stable lifting displacement. The equipment is not very versatile. Therefore, we propose a lifting platform guide wheel assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting platform guide wheel assembly. Through a displacement mechanism and a quick-release mechanism, it solves the problem that the relatively fixed spacing and position of the guide wheels may not be conducive to sliding when facing different types of lifting platform guide rails, which in turn makes it difficult for the overall equipment to maintain a stable lifting displacement and results in low versatility of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a guide wheel assembly for a lift, including a fixed leg, the inner wall of which is provided with a plurality of displacement grooves, the outer wall of which is fixedly connected with a mounting plate, and the outer wall of which is provided with a displacement mechanism.

[0007] The displacement mechanism includes several threaded rod seats, the outer walls of which are fixedly connected to the outer walls of fixed legs. Each of the threaded rod seats has a threaded rod rotatably connected to its inner wall, the threaded rod passing through the threaded rod seat to the outer wall. A knob is fixedly connected to the outer wall of the threaded rod. A second threaded rod seat is fixedly connected to the outer wall of the fixed leg, the outer wall of the second threaded rod seat is rotatably connected to the outer walls of the several threaded rods. Displacement blocks are slidably connected to the inner walls of several displacement grooves. Several fixed frames are fixedly connected to the outer wall of the fixed leg, and pulley seats are fixedly connected to the outer walls of the several fixed frames. A pulley is rotatably connected to the inner wall of the pulley seat.

[0008] Furthermore, the outer wall of the displacement block is provided with a quick-release mechanism, which includes a fixing plate, and the outer wall of the fixing plate is fixedly connected to the outer wall of the displacement block.

[0009] Furthermore, a rotating shaft is rotatably connected to the outer wall of the fixed plate, and a clamping plate is fixedly connected to the outer wall of the rotating shaft.

[0010] Furthermore, a fixed roller is fixedly connected to the outer wall of the card plate, and a guide wheel is slidably connected to the outer wall of the fixed roller.

[0011] Furthermore, the fixed roller extends through the guide wheel to the outer wall, and a pin seat is fixedly connected to the outer wall of the fixed roller.

[0012] Furthermore, the inner wall of the pin seat is provided with a plurality of pin grooves, and the inner walls of the plurality of pin grooves are slidably connected with locking pins.

[0013] Furthermore, a push button is fixedly connected to the outer wall of the locking pin, and a spring is fixedly connected to the outer wall of the locking pin.

[0014] Furthermore, the outer wall of the spring is fixedly connected to the inner wall of the pin groove, and several threaded rod seats are symmetrically distributed around the threaded rod seat two.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a displacement block. If it is necessary to adjust the spacing and position of several guide wheels according to the length of the guide rail, several knobs can be rotated. The knobs will drive the threaded rod to rotate, which in turn will drive the displacement block to move. The displacement block will then drive the fixed plate to move, which in turn will drive the rotating shaft to move. The rotating shaft will then drive the fixed roller to move, which in turn will drive the guide wheels to move, thus achieving the adjustment of the position. This allows for free adjustment of the spacing and position of the guide wheels to adapt to different types of lifting platform guide rails, ensuring that the entire equipment can perform stable lifting and displacement. The simple operation also improves the versatility of the equipment.

[0017] 2. This utility model incorporates locking pins. If the guide wheel wears out due to prolonged use, several push buttons can be engaged. These push buttons will displace the locking pins, causing them to release the spring and loosen their grip on the guide wheel. At this point, the guide wheel can be pulled out of the fixed roller. Subsequently, a new guide wheel can be installed and the push buttons released. The springs will then reposition the locking pins to lock the guide wheel and restrict its displacement. This allows for quick and convenient disassembly and installation of the guide wheel. When the guide wheel wears out due to prolonged use, it can be replaced promptly to ensure the equipment can be put back into normal operation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] One specific application of this embodiment is:

[0033] When workers need to use the equipment, they can use the mounting plate 102 to install the entire equipment on the lifting platform, then place several guide wheels 305 inside the guide rails of the lifting platform, and wind the ropes provided by the lifting platform around several pulleys 208 to complete the installation. If it is necessary to adjust the spacing of several guide wheels 305 according to the length of the guide rail, several knobs 203 can be rotated. The knobs 203 will drive the threaded rod 202 to rotate, the threaded rod 202 will drive the displacement block 205 to move, the displacement block 205 will drive the fixed plate 301 to move, the fixed plate 301 will drive the rotating shaft 302 to move, and the rotating shaft 302 will... The fixed roller 304 moves, which in turn drives the guide wheel 305 to move to adjust its position. If the guide wheel 305 wears out after long-term use, several push buttons 309 can be engaged. These push buttons 309 will cause the locking pins 308 to move. The locking pins 308 will no longer lock the guide wheel 305 while compressing the spring 310. At this point, the guide wheel 305 can be pulled out of the fixed roller 304. Then, the new guide wheel 305 is reset and installed, and the push buttons 309 are released. Subsequently, the locking pins 308 will be reset by the spring 310 to lock the guide wheel 305 and restrict its movement.
