Abstract

This utility model relates to the field of lifting device technology and discloses a traction drive lifting device for a three-dimensional parking garage. It includes a machine room welding platform, with wire rope anti-derailment frames fixedly installed on both sides of the upper surface of the welding platform. A lifting component is installed inside the wire rope anti-derailment frame, and a drive component is installed on the upper surface of the welding platform. The drive component and the lifting component work together. This utility model uses a traction wheel drive, with the wire rope and traction wheel relying on friction for transmission. The friction noise generated during operation is relatively low. Noise generation is often accompanied by equipment vibration, which accelerates the wear of equipment parts and reduces the service life of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically to a traction drive lifting device for a three-dimensional parking garage. Background Technology

[0002] With the acceleration of urbanization, the number of cars has exploded, while urban land resources are becoming increasingly scarce. Traditional surface parking lots, due to their large footprint and low space utilization, can no longer meet the ever-increasing parking demand. Against this backdrop, mechanical multi-level parking garages have emerged as a shining new star, playing a crucial role in solving urban parking problems with their unique advantages of fully utilizing vertical space and significantly improving land utilization.

[0003] Existing devices have some drawbacks in use. For example, traditional chain-driven lifting devices for automated parking garages generate significant mechanical noise during operation due to the meshing between the chain and sprocket, the stretching of the chain, and vibration. This noise is especially noticeable during frequent starts, stops, and speed changes, causing disturbance to the surrounding environment and residents' lives. Utility Model Content

[0004] The purpose of this utility model is to provide a traction drive lifting device for a three-dimensional parking garage, which solves the problem that traditional chain-driven three-dimensional parking garage lifting devices generate significant mechanical noise during operation due to the meshing between the chain and sprocket, chain stretching, and vibration.

[0005] This utility model provides the following technical solution: a traction drive lifting device for a three-dimensional parking garage, including a machine room welding platform, on both sides of the upper surface of the machine room welding platform are fixedly installed with wire rope anti-detachment frames, a lifting component is provided inside the wire rope anti-detachment frames, and a drive component is provided on the upper surface of the machine room welding platform, and the drive component and the lifting component are used in cooperation.

[0006] As a preferred embodiment of the above technical solution, the lifting assembly includes a two-stud vertical bearing seat that is symmetrically fixed to the inner bottom wall of the wire rope anti-derailment frame. A traction wheel shaft two and a traction wheel shaft one are rotatably connected to the two-stud vertical bearing seats on both sides. A traction wheel is fixedly sleeved on the outer wall of both the traction wheel shaft two and the traction wheel shaft one. A traction steel wire rope is wound on the outer wall of the traction wheel.

[0007] As a preferred embodiment of the above technical solution, the drive assembly includes a main drive motor fixedly installed on the welding platform in the machine room. The output end of the main drive motor is fixedly connected to a traction wheel shaft one. A clamp coupling one is fixedly connected to the end of the traction wheel shaft one. A lifting drive shaft is fixedly connected to the clamp coupling one. A clamp coupling two is connected to the end of the lifting drive shaft away from the clamp coupling one. The clamp coupling two is fixed to the traction wheel shaft two.

[0008] As a preferred embodiment of the above technical solution, a flat key one is fixedly connected to the outer wall of the traction wheel shaft one, a flat key two is fixedly connected to the outer wall of the traction wheel shaft two, and a flat key three is fixedly connected to the outer wall of the lifting transmission shaft.

[0009] As a preferred embodiment of the above technical solution, both the second traction wheel shaft and the first traction wheel shaft are rotatably connected to a two-stub vertical bearing housing via self-aligning roller bearings.

[0010] As a preferred embodiment of the above technical solution, locking nuts are provided on both sides of the traction wheel, and the locking nuts are respectively threaded onto the outer walls of the second traction wheel shaft and the first traction wheel shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a traction sheave drive is used, and the steel wire rope and the traction sheave rely on friction for transmission. The friction noise generated during operation is relatively small. Noise generation is often accompanied by equipment vibration, which accelerates the wear of equipment parts and reduces the service life of the equipment. The traction sheave drive effectively reduces operating noise and also reduces equipment vibration. The smooth operation of the steel wire rope on the traction sheave reduces the additional stress caused by vibration, reduces the wear of key components such as steel wire rope and traction sheave, reduces the frequency of equipment maintenance and replacement, and lowers operating costs.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a traction drive lifting device for a three-dimensional parking garage, including a machine room welding platform 1. Steel wire rope anti-detachment frames 11 are fixedly installed on both sides of the upper end face of the machine room welding platform 1. A lifting component 16 is provided inside the steel wire rope anti-detachment frame 11. A drive component 17 is provided on the upper end face of the machine room welding platform 1. The drive component 17 and the lifting component 16 are used in cooperation. The drive component drives the lifting component to move. The steel wire rope anti-detachment frame 11 can prevent the steel wire rope from breaking and being thrown out over a large range during rotation, thus avoiding damage to the outside.

[0021] As one implementation method in this embodiment, such as Figure 2As shown, the lifting assembly 16 includes two studded vertical bearing seats 7 symmetrically fixed to the inner bottom wall of the wire rope anti-derailment frame 11. Traction sheave shaft 2 5 and traction sheave shaft 1 4 are rotatably connected to the two studded vertical bearing seats 7 on both sides. Both traction sheave shaft 2 5 and traction sheave shaft 1 4 are rotatably connected to the two studded vertical bearing seats 7 via self-aligning roller bearings 8. Traction sheaves 3 are fixedly sleeved on the outer walls of both traction sheave shaft 2 5 and traction sheave shaft 1 4. Locking nuts 10 are provided on both sides of the traction sheave 3, and are threadedly fixed to the outer walls of traction sheave shaft 2 5 and traction sheave shaft 1 4 respectively. The locking nuts 10 can firmly fix the traction sheaves 3. The position of the traction sheave 3 is designed to prevent axial slippage on the shaft, ensuring that the traction sheave 3 rotates synchronously and stably with the shaft. A traction steel wire rope 15 is wound around the outer wall of the traction sheave 3. The drive assembly 17 includes a main drive motor 2 fixedly installed on the welding platform 1 in the machine room. The output end of the main drive motor 2 is fixedly connected to the traction sheave shaft 4. A clamp coupling 9 is fixedly connected to the end of the traction sheave shaft 4. A lifting drive shaft 6 is fixedly connected to the clamp coupling 9. A clamp coupling 18 is connected to the end of the lifting drive shaft 6 away from the clamp coupling 9. The clamp coupling 18 is fixed to the traction sheave shaft 5. (Specific usage...) During the process, the main drive motor 2 starts running after receiving the start signal. Its output end drives the traction sheave shaft 4 to rotate. Since the traction sheave shaft 4 is connected to the lifting drive shaft 6 through the clamp coupling 9, and the lifting drive shaft 6 is connected to the traction sheave shaft 5 through the clamp coupling 18 (clamp coupling 9 and clamp coupling 18 are JQ type clamp couplings), the rotation of the traction sheave shaft 4 will be transmitted to the lifting drive shaft 6 and the traction sheave shaft 5 in sequence, causing the traction sheave shaft 5 and the traction sheave shaft 4 to rotate simultaneously. The traction sheave 3, which is fixedly sleeved on the outer wall of the traction sheave shaft 5 and the traction sheave shaft 4, will rotate accordingly, and the traction steel wire will rotate. Rope 15 is wound around the outer wall of traction sheave 3. Under the action of friction between traction sheave 3 and traction wire rope 15, traction wire rope 15 begins to move. Due to the restriction of wire rope anti-derailment frame 11, traction wire rope 15 always runs within the specified track and will not derail. The movement of traction wire rope 15 drives the connected car platform to start to rise smoothly. During the rising process, the various components in lifting assembly 16 work together. Self-aligning roller bearing 8 can automatically adjust the skew of traction sheave shaft, reduce friction and vibration caused by shaft skew, and ensure that car platform runs along the predetermined trajectory, avoiding swaying or deviation.

[0022] As one implementation method in this embodiment, such as Figure 2As shown, a flat key 12 is fixedly connected to the outer wall of traction wheel shaft 1 4, a flat key 2 is fixedly connected to the outer wall of traction wheel shaft 2 5, and a flat key 3 14 is fixedly connected to the outer wall of lifting drive shaft 6 13. Through the setting of flat keys 1 12, flat keys 2 13 and flat keys 3 14, the coaxiality requirement between various components in the traction drive lifting device of the three-dimensional garage is high. If the coaxiality deviation is too large, it will lead to increased friction between components, generating vibration and noise, and even affecting the normal operation of the equipment. The flat keys, through their precise dimensions and fit, can enable the shaft and connecting parts to maintain good alignment during rotation.

[0023] Working principle: During use, the operator sends a start command to the drive assembly 17 via the control panel. Upon receiving the start signal, the main drive motor 2 begins to run, and its output drives the traction sheave shaft 4 to rotate. Since the traction sheave shaft 4 is connected to the lifting drive shaft 6 via a clamp coupling 9, and the lifting drive shaft 6 is connected to the traction sheave shaft 5 via a clamp coupling 18, the rotation of the traction sheave shaft 4 is sequentially transmitted to the lifting drive shaft 6 and the traction sheave shaft 5, causing the traction sheave shaft 5 and the traction sheave shaft 6 to rotate. Simultaneously, the first traction sheave shaft 4 rotates, and the second traction sheave shaft 5 and the traction sheave 3 fixedly sleeved on the outer wall of the first traction sheave shaft 4 rotate accordingly. The traction steel wire rope 15 is wound around the outer wall of the traction sheave 3. Under the action of friction between the traction sheave 3 and the traction steel wire rope 15, the traction steel wire rope 15 begins to move. Due to the restriction of the steel wire rope anti-derailment frame 11, the traction steel wire rope 15 always runs within the specified track and will not derail. The movement of the traction steel wire rope 15 drives the connected car platform to begin to rise steadily.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
