Description

Technical Field

[0001] This utility model relates to a traction passenger elevator guide device. Background Technology

[0002] A traction passenger elevator is a vertical transportation tool driven by a traction machine, relying on the friction between the traction rope and the traction sheave groove to move the car and counterweight up and down. The guiding device is an important component of the elevator system. Its function is to limit the horizontal movement of the car and counterweight, ensure that the car and counterweight run smoothly along the guide rails, and prevent swaying or vibration during operation.

[0003] Currently, common passenger elevator guiding devices mainly employ sliding guide shoes or fixed rolling guide shoes. Sliding guide shoes typically consist of a shoe liner and a shoe body. The shoe liner slides directly in contact with the guide rail, resulting in high frictional resistance, high operating noise, easy wear, and the need for regular lubrication. While fixed rolling guide shoes replace sliding friction with rolling friction, reducing frictional resistance, the gap between the rollers and the guide rail is usually fixed. After long-term elevator operation, gaps can easily appear between the rollers and the guide rail due to installation errors, guide rail deformation, or roller wear. This leads to impacts and vibrations during car operation, affecting passenger comfort and generating noise. Therefore, a traction passenger elevator guiding device needs to be designed to solve these problems. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a traction passenger elevator guiding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a traction passenger elevator guiding device, including an elevator guide rail and a guide shoe. The elevator guide rail includes a mounting plate and a guide rail body. The mounting plate is fixedly connected to the elevator shaft, and the guide shoe is fixedly connected to the elevator car. The guide shoe has a U-shaped structure and includes a fixing part and two mounting parts that are perpendicularly connected to both ends of the fixing part. The two mounting parts are located on both sides of the guide rail body. A roller mechanism is provided between each mounting part and the guide rail body. The roller mechanism includes a fixing component, a roller mounting seat, and a spring assembly. The roller mounting seat is located between the mounting part and the guide rail body. The fixing component is fixedly connected to the mounting part. The spring assembly is connected between the fixing component and the roller mounting seat and is in a compressed state. Rollers are rotatably mounted on both ends of the roller mounting seat, and both rollers are in close contact with the side of the guide rail body.

[0006] Preferably, the fixing assembly includes a fixing plate and four fixing shafts. The fixing plate is located between the mounting part and the roller mounting seat, and the fixing plate is in contact with the mounting part. The four fixing shafts are fixedly inserted through the fixing plate and are arranged in a rectangular shape. One end of each fixing shaft passes through the mounting part and is provided with an external thread. The external thread is connected to a locking nut. The roller mounting seat is movably sleeved on the other end of the four fixing shafts. The spring assembly includes four compression springs. The four compression springs are respectively sleeved on the outside of the four fixing shafts, and both ends of each compression spring are fixedly connected to the fixing plate and the roller mounting seat, respectively.

[0007] Preferably, the mounting part is provided with an oblong hole for the fixing shaft to pass through.

[0008] Preferably, the side of the guide rail body is provided with a limiting protrusion located between the two rollers.

[0009] Preferably, a pad is provided between the locking nut and the mounting part.

[0010] Preferably, a reinforcing rib is provided between the mounting part and the fixing part.

[0011] The advantages and beneficial effects of this utility model are as follows: It provides a traction passenger elevator guiding device with a reasonable structure. By improving the roller mechanism structure, the spring can push the roller to move in the direction of the guide rail, automatically eliminating the gap between the roller and the guide rail body, and always maintaining close contact between the roller and the side of the guide rail body, thus avoiding impact and vibration.

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] The specific technical solution of this utility model is as follows: In one specific embodiment, such as Figure 1 As shown, this utility model provides a traction passenger elevator guiding device, including an elevator guide rail 10 and a guide shoe 20.

The guide shoe 20 has a U-shaped structure and includes a fixing part 21 and two mounting parts 22 respectively perpendicularly connected to both ends of the fixing part 21. The two mounting parts 22 are respectively located on both sides of the guide rail body 12. Each mounting part 22 and the guide rail body... A roller mechanism is provided between the mounting part 22 and the guide rail body 12. The roller mechanism includes a fixing component 30, a roller mounting base 40 and a spring assembly 50. The roller mounting base 40 is located between the mounting part 22 and the guide rail body 12. The fixing component 30 is fixedly connected to the mounting part 22. The spring assembly 50 is connected between the fixing component 30 and the roller mounting base 40 and is in a compressed state. Rollers 41 are rotatably mounted on both ends of the roller mounting base 40. Both rollers 41 are in close contact with the side of the guide rail body 12.

[0017] By adopting the above solution, the working principle of the traction passenger elevator guide device provided by this utility model is as follows: by connecting a spring assembly 50 in a compressed state between the fixed component 30 and the roller mounting seat 40, the spring assembly 50 applies an elastic preload to the roller mounting seat 40, thereby pushing the roller 41 to move in the direction of the guide rail body 12, automatically eliminating the gap between the roller 41 and the guide rail body 12, and always maintaining close contact between the roller 41 and the side of the guide rail body 12, thus avoiding impact and vibration.

[0018] In another specific embodiment, such as Figure 1 and Figure 2 As shown, the fixing assembly 30 includes a fixing plate 31 and four fixing shafts 32. The fixing plate 31 is located between the mounting part 22 and the roller mounting seat 40, and the fixing plate 31 is in contact with the mounting part 22. The four fixing shafts 32 are fixedly inserted through the fixing plate 31 and are arranged in a rectangular shape. One end of each fixing shaft 32 passes through the mounting part 22 and is provided with an external thread. The external thread is connected to a locking nut 60. The roller mounting seat 40 is movably sleeved on the other end of the four fixing shafts 32. The spring assembly 50 includes four compression springs 51. The four compression springs 51 are respectively sleeved on the outside of the four fixing shafts 32, and the two ends of each compression spring 51 are fixedly connected to the fixing plate 31 and the roller mounting seat 40, respectively.

[0019] The above solution is adopted: by setting four compression springs 51 to apply elastic preload to the roller mounting seat 40, so that the roller 41 maintains a stable and tight contact with the side of the guide rail body 12.

[0020] In another specific embodiment, the mounting part (22) is provided with a waist-shaped hole through which the fixing shaft (32) passes.

[0021] In another specific embodiment, such as Figure 1 and Figure 2 As shown, the side of the guide rail body 12 is provided with a limiting protrusion 13 located between the two rollers 41.

[0022] The above solution is adopted: the horizontal offset of the two rollers 41 is limited by setting the limiting protrusion 13.

[0024] In another specific embodiment, such as Figure 1 As shown, a reinforcing rib 23 is provided between the mounting part 22 and the fixing part 21.
