Description

Technical Field

[0001] This utility model relates to the field of elevator guide wheel technology, and in particular to an elevator guide wheel device with adaptive adjustment function. Background Technology

[0002] Elevator guide wheels are core mechanical components in elevator systems used to guide the movement of the car and counterweight. Through a pulley structure, the guide wheels restrict the car and counterweight to move only vertically along the guide rails, preventing lateral deviation or rotation and ensuring stable running trajectory. The elevator guide wheels, guide rails, and guide shoes together constitute the guiding system. The guide shoes are in direct contact with the guide rails, while the guide wheels indirectly constrain the car position through steel wire ropes. In a double-wound traction system, the guide wheels increase the horizontal distance between the car and counterweight by changing the winding path of the steel wire ropes, thereby improving the traction capacity. A utility model application with application number 202122323948.6 discloses an elevator guide wheel device. Through the cooperation of the rotating wheel, axle, and fixing mechanism, the rotating wheel drives the axle to extend into the semi-circular groove between the arc-shaped blocks and square blocks on both sides. By rotating the bolts at the four corners in sequence, the two sets of ear plates on both sides are connected sequentially, thereby fixing the arc-shaped blocks and square blocks on both sides. This facilitates the installation of the axle on the rotating wheel in the semi-circular groove between the arc-shaped blocks and square blocks, ensuring efficiency. It solves the problem of existing elevator guide wheel devices being difficult to fix during installation, affecting efficiency. Through the cooperation of the rotating wheel, axle, groove, steel wire, horizontal plate, rotating mechanism, and anti-detachment mechanism, rotating the handle drives the threaded rod to move downward within the circular block. The threaded rod rotates within the rotating block through an internal bearing, causing the rotating block to drive the frame downward. The downward movement of the frame causes the vertical rods on both sides to move downward within the circular holes on both sides of the horizontal plate. The frame drives the grooved wheel downward to adhere to the rotating wheel. As the rotating wheel rotates, the two steel wires are transmitted through their respective grooves. The shaft rotates within the frame via an internal bearing, and the grooved wheel limits the steel wire to prevent it from detaching from the groove. This solves the problem that existing elevator guide wheel devices cannot limit the steel wire, making it easy for the steel wire to detach from the guide wheel groove. However, in the aforementioned elevator guide wheel device, the rotation of the wheel synchronously drives the movement of multiple steel wires. The tension of different steel wires is inconsistent and cannot be adaptively adjusted. After long-term use, this can easily lead to the safety hazard of a single steel wire breaking due to prolonged load. In the aforementioned elevator guide wheel device, the number of guide grooves on the guide wheel is fixed. When facing different numbers of steel wires for guidance, the elevator guide wheel can only be replaced. It is impossible to adaptively adjust the guide wheel according to the number of steel wires. Therefore, this utility model proposes an elevator guide wheel device with adaptive adjustment function to solve the problems existing in the prior art. Utility Model Content

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides an elevator guide wheel device with adaptive adjustment function, including a fixed frame 1, a guide wheel body 2, a tension adjustment mechanism, a guide wheel extension mechanism, and a limiting guide mechanism. The guide wheel body 2 is rotatably mounted in the middle of the fixed frame 1. The tension adjustment mechanism includes a first bracket 3, mounting bolts 4, a first through hole 5, a telescopic slide rod 6, a spring 7, an adjusting wheel 8, and a sliding fixing mechanism. The first brackets 3 are fixedly arranged on both sides of the fixed frame 1. Mounting bolts 4 are screwed into the top of the first brackets 3. A first through hole 5 is opened below the first brackets 3. A telescopic slide rod 6 is slidably inserted into the first through hole 5. A spring 7 is fixedly mounted inside the telescopic slide rod 6. An adjusting wheel 8 is rotatably mounted inside the spring 7. Multiple sets of springs 7 are arranged in a row. The outer side of the spring 7 is fixedly connected to the lower part of the first bracket 3. When the elevator guide wheel is working, the elevator wire is wound around the guide wheel body 2. The wire is supported by the adjusting wheel 8. The elasticity of the spring 7 is used to adjust the tension of the wire according to the tension of the wire, so as to realize the adaptive adjustment of the tension of each wire. This solves the problem that when the rotating wheel drives multiple wires to move synchronously, the tension of different wires is inconsistent and cannot be adaptively adjusted. After long-term use, it is easy to cause the wire to break due to long-term load on a single wire. A sliding fixing mechanism is provided between the fixed frame 1 and the first bracket 3. A guide wheel extension mechanism is provided at the front and rear of the guide wheel body 2. A limiting guide mechanism is provided at the upper middle part of the fixed frame 1.

[0016] The sliding fixing mechanism includes a slide groove 9, a slider 10, a mounting threaded hole 11, and a second through hole 12. The fixing frame 1 has slide grooves 9 symmetrically opened on both sides. The slider 10 is fixedly installed on the upper inner side of the first bracket 3. The fixing frame 1 has mounting threaded holes 11 symmetrically opened on both sides, and the mounting threaded holes 11 correspond to the positions of the mounting bolts 4. The first bracket 3 has second through holes 12 symmetrically opened on the upper upper side, and the second through holes 12 correspond to the positions of the mounting threaded holes 11. Before self-adjusting the steel wire, the first bracket 3 is inserted into both sides of the fixing frame 1 along the slide groove 9 through the slider 10 so that the adjusting wheel 8 is aligned with each steel wire. During installation, the mounting bolts 4 are inserted into the second through holes 12 and then screwed into the mounting threaded holes 11 to achieve installation and fixing.

[0017] The guide wheel extension mechanism includes an extension shaft 13, a first threaded hole 14, an upper extension block 15, a lower extension block 16, a second threaded hole 17, and an extension bolt 18. The extension shaft 13 is symmetrically fixed in the middle of the guide wheel body 2. The first threaded hole 14 is opened around the front and rear of the guide wheel body 2. The upper extension block 15 is installed on the upper front and rear sides of the guide wheel body 2, and the lower extension block 16 is installed on the lower front and rear sides of the guide wheel body 2. The second threaded hole 17 is opened around the upper extension block 15 and the lower extension block 16. The extension bolt 18 is threadedly engaged between the first threaded hole 14 and the second threaded hole 17. When the guide wheel body 2 needs to accommodate more steel wires, the upper extension block 15 and the lower extension block 16 are assembled and installed on the front and rear sides of the guide wheel body 2. The extension bolt 18 is screwed into the first threaded hole 14 and the second threaded hole 17 to fix it. This allows the number of guide wires limited and guided by the guide wheel body 2 to be increased by expanding the upper extension block 15 and the lower extension block 16 without replacing the elevator guide wheel, solving the problem that the guide wheel cannot be adaptively adjusted according to the number of steel wires.

[0018] Both the upper extension block 15 and the lower extension block 16 have semi-circular cross sections, and the positions of the first threaded hole 14 and the second threaded hole 17 correspond to each other for easy and quick installation.

[0019] The limiting guide mechanism includes a second bracket 19, a rotating shaft 20, a limiting guide roller 21, and a limiting guide groove 22. The second bracket 19 is fixedly installed in the middle of the fixed frame 1. The rotating shaft 20 is rotatably installed inside the second bracket 19. The limiting guide roller 21 is coaxially fixed on the rotating shaft 20. The limiting guide roller 21 is provided with limiting guide grooves 22. The limiting guide roller 21 is in corresponding vertical position with the guide wheel body 2. The limiting guide roller 21 and the guide wheel body 2 cooperate to clamp the steel wire and rotate, effectively preventing the steel wire from deviating and dislodging when the elevator is working.

[0020] Before operation, the elevator guide wheel device with adaptive adjustment function pushes the first bracket and slider to slide along the slide groove to a suitable position according to the position of the steel wire, so that the adjusting wheel contacts the steel wire. When the elevator is running, the steel wire passes around the guide wheel body and is supported by the adjusting wheel. The spring deforms elastically according to the real-time tension of the steel wire, and automatically adjusts the position of the adjusting wheel to balance the tension of each steel wire. The tension of the steel wire is adjusted in real time by the spring supporting the adjusting wheel. When it is necessary to expand the number of steel wires guided by the guide wheel body, the upper expansion block and the lower expansion block are installed at the front and rear of the guide wheel body to extend the length of the guide wheel body. This makes it convenient to expand the load-bearing range of the guide wheel without replacing the guide wheel body. The limiting guide roller rotates synchronously with the guide wheel body to guide and limit the steel wire.
