Description

Technical Field

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

[0002] With the continuous development of the times, the demand for elevators is becoming increasingly essential. Whether it's a car elevator or a regular elevator, the requirements for manufacturing technology are becoming increasingly stringent. The guide wheels of an elevator primarily increase the distance between the car and the counterweight and change the direction of the traction ropes. The guide wheels are fixed to the load-bearing blocks of the elevator system via guide wheel frames and play a crucial role in the elevator's operation. Therefore, the installation requirements for the guide wheels are also becoming increasingly stringent. Current technology uses guide wheels with fixed positions, making it impossible to adjust the installation distance according to the guide wheel's dimensions. Furthermore, the position of the wire rope limiting levers in current technology is also fixed, making it impossible to adjust the lever's position according to the guide wheel's dimensions, which has certain limitations. Therefore, there is an urgent need for a new elevator guide wheel mechanism. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figure 1-2 This utility model provides an elevator guide wheel mechanism, including a square bracket 1. Two support plates 2 are fixedly connected to both sides of the top surface of the square bracket 1. Two mounting plates 3 are slidably connected between the two support plates 2. The two mounting plates 3 are symmetrically arranged. Two guide wheel bodies 4 are detachably connected between the two mounting plates 3. An adjustment component for adjusting the distance between the two mounting plates 3 is installed inside the square bracket 1. Two moving blocks 5 are slidably connected along the length of each mounting plate 3. A stop bar 6 is provided on the side of the guide wheel body 4. The stop bar 6 slides through the two moving blocks 5 located on different mounting plates 3. A control component for controlling the distance between the stop bar 6 and the guide wheel body 4 is installed inside the support plate 2. By sliding the two mounting plates 3 inside the square bracket 1 and adjusting the distance between the two mounting plates 3 by the adjustment component, the two installation distances can be adjusted according to the size specifications of the guide wheel. At the same time, the control component can adjust the distance between the stop bar 6 and the guide wheel body 4, so that it can be adjusted according to the change of the guide wheel size, ensuring that the stop bar 6 limits the wire rope.

[0019] Further optimization of the design involves adjusting the components, including a fixing block 7 located on and fixedly connected to the bottom surface of the mounting plate 3. A first bidirectional threaded rod 8 is rotatably connected within the square bracket 1. The first bidirectional threaded rod 8 passes through both fixing blocks 7 and is threadedly connected to them. The two fixing blocks 7 are located on opposite sides of the thread direction of the first bidirectional threaded rod 8. One end of the first bidirectional threaded rod 8 passes through the square bracket 1 and is fixedly connected to a first adjustment knob 9. The first adjustment knob 9 drives the first bidirectional threaded rod 8 to rotate, thereby causing the two fixing blocks 7 to move towards or away from each other, thus moving the two mounting plates 3 and adjusting the distance between them according to the size specifications of the guide wheel body 4.

[0020] A further optimized scheme includes a receiving groove 10 within the support plate 2. A slider 11 is slidably connected to the moving block 5 within the receiving groove 10. A second bidirectional threaded rod 12 is rotatably connected within the receiving groove 10, passing through both sliders 11 and threadedly connected to them. The two sliders 11 are located on opposite sides of the thread direction of the second bidirectional threaded rod 12. A connecting plate 13 rotatably connects the corresponding slider 11 to the moving block 5. One end of the second bidirectional threaded rod 12 passes through the side wall of the receiving groove 10 and is fixedly connected to a second adjusting knob 14. The second adjusting knob 14 drives the second bidirectional threaded rod 12 to rotate, thereby causing the two sliders 11 to move towards or away from each other. During movement, the sliders 11 push or pull the moving block 5 along the length of the mounting plate 3 via the connecting plate 13, thus causing the stop rod 6 to move closer to or away from the guide wheel body 4, achieving adjustment of the position of the stop rod 6.

[0021] The design was further optimized so that the stop bar 6 is set perpendicular to the mounting plate 3, and the axis of the stop bar 6 is at the same height as the axis of the guide wheel body 4. This facilitates the stop bar 6 in limiting the steel wire rope on the guide wheel body 4.

[0022] In a further optimized design, balance plates 15 are rotatably connected to both ends of the stop lever 6, and springs 16 are fixedly connected between the balance plates 15 and the moving block 5. Under the action of the two springs 16, the stop lever 6 will not experience severe displacement and will always remain in the middle position of the square bracket 1, which is beneficial to the stability of the overall structure.

[0023] In a further optimized design, mounting plates 3 are detachably connected to mounting bases 17 corresponding to the guide wheel body 4, allowing the guide wheel body 4 to be rotatably mounted within the two mounting bases 17. This facilitates the disassembly and installation of the guide wheel body 4.

[0024] In a further optimized design, a base plate 18 is fixedly connected inside the square bracket 1, and the mounting plate 3 slides on the base plate 18. The base plate 18 is used to support the mounting plate 3.

[0025] The working process of this utility model is as follows: In use, the first adjusting knob 9 drives the first bidirectional threaded rod 8 to rotate, which in turn drives the two mounting plates 3 to move towards or away from each other. This allows the installation position to be adjusted according to the size of the guide wheel body 4. Then, the guide wheel body 4 is installed through the mounting base 17. During the adjustment of the mounting plate 3, the two moving blocks 5 move along the length of the mounting plate 3 under the action of the connecting plate 13. Then, the distance between the stop rod 6 and the guide wheel body 4 is adjusted by rotating the second adjusting knob 14. The second adjusting knob 14 drives the second bidirectional threaded rod 12 to rotate, which in turn drives the two sliders 11 to move towards or away from each other. During the movement, the two sliders 11 push the moving blocks 5 to slide along the length of the mounting plate 3 through the connecting plate 13, thereby driving the stop rod 6 to move and ensuring that the stop rod 6 can apply pressure to the wire rope.
