Description

Technical Field

[0001] This utility model belongs to the technical field of three-dimensional parking equipment, specifically relating to a shallow pit car cantilever lift. Background Technology

[0002] Currently, among the planar moving mechanical parking equipment on the market, lifts are mainly divided into four-column and two-column types. Four-column lifts can have four lifting points and require a shallow pit, but they necessitate a lift room at the top. Two-column lifts do not require a lift room, but due to the longer cantilever, they require very tall guide columns to transfer the bending moment of the cantilever to the guide rails of the columns. The taller guide columns result in a deeper pit and higher civil engineering costs. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a shallow pit car cantilever lift that has no top lifting machine room, reduces the bending moment of the cantilever vehicle platform on the lifting guide rail, and has low civil engineering costs.

[0004] The purpose of this utility model and the solution to its main technical problem are achieved by the following technical solution:

[0005] This utility model discloses a shallow foundation pit car cantilever lift, comprising a frame, an auxiliary support platform, a cantilever car platform, a counterweight, a lifting guide rail, a counterweight guide rail, a lifting system, a lifting chain, and a buffer seat. The frame is characterized by the following: the lifting guide rail, the counterweight guide rail, and the lifting system are mounted on the frame; the cantilever car platform is mounted on the lifting guide rail; the cantilever car platform is mounted on the auxiliary support platform; the upper end of the lifting chain is wound around the lifting system and connected to the cantilever car platform; the lower end of the lifting chain is connected to the counterweight, which is mounted on the counterweight guide rail; and a buffer seat is installed below the cantilever car platform and the counterweight.

[0006] Connecting brackets are mounted on the frame.

[0007] The auxiliary support platform is equipped with hangers and lifting points.

[0008] The cantilever vehicle platform is equipped with guide columns, movable pulleys, guide wheel A, and anti-fall devices.

[0009] The counterweight is equipped with a guide wheel B.

[0010] The cantilevered vehicle platform can move up and down within the lifting guide rail.

[0011] The lifting chain is fixed at one end to the lifting machine system and at the other end to the auxiliary support platform, with the chain passing around the counterweight and the cantilever truck platform in the middle.

[0012] Compared with existing technologies, this utility model has significant advantages. As can be seen from the above technical solution: a lifting guide rail, a counterweight guide rail, and a lifting system are installed on the frame. A cantilever vehicle platform is installed on the lifting guide rail and an auxiliary support platform. The upper end of the lifting chain is wound around the lifting system and connected to the cantilever vehicle platform. The lower end of the lifting chain is connected to the counterweight, which is installed on the counterweight guide rail. A buffer seat is installed below the cantilever vehicle platform and the counterweight. The frame is a two-column type, serving as the main support structure, and is fixed to the garage main body by welding to the pre-embedded parts via connecting brackets. The auxiliary support platform is installed on the upper part of the frame, with part of it welded to the pre-embedded parts in the garage main body via hangers. This platform converts the two lifting points of the cantilever vehicle platform into four lifting points, reducing the bending moment of the cantilever vehicle platform on the lifting guide rail. The cantilever vehicle platform is characterized by: the guide columns are shorter than traditional ones, upgrading the traditional two-point direct lifting method to a four-point moving pulley lifting mode. The four-point cantilever truck platform is not subject to bending moments, allowing for further lightweight design and cost reduction. Additionally, the short guide columns result in a shallower elevator pit, further reducing civil engineering costs. The counterweight is equipped with guide wheels B, which move up and down on the counterweight guide rails, reducing the load on the hoist. The lifting guide rails guide the cantilever truck platform. The counterweight guide rails guide the counterweight. The hoist system is installed on the upper side of the frame to lift the cantilever truck platform. The lifting chain, fixed at one end to the hoist system and the other end to the auxiliary support platform, passes through the counterweight and cantilever truck platform, making the cantilever truck platform a four-point lifting mechanism with movable pulleys. Buffers are installed at the corresponding upper and lower ends of the counterweight and the cantilever truck platform, serving as secondary buffer protection in case of equipment failure. This invention achieves a shallow foundation pit, reduces civil engineering construction costs, uses four lifting points to lift vehicles, making the platform more stable, and has the lifting machine system installed on the side above the frame, eliminating the need for a machine room directly above the frame and not affecting the upward lifting space of the vehicle. In short, this utility model features a shallow foundation pit, no top lifting machine room, reduces the bending moment of the cantilever vehicle platform on the lifting guide rail, and has low civil engineering costs.

Detailed Implementation

[0025] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structure, features, and effects of this utility model.

[0026] This utility model discloses a shallow foundation pit car cantilever lift, comprising a frame 1, an auxiliary support platform 2, a cantilever vehicle platform 3, a counterweight 4, lifting guide rails 5 and 6, a lifting system 7, a lifting chain 8, and a buffer seat 9.

One end of the lifting chain 8 is fixed to the lifting machine system 7, and the other end is fixed to the auxiliary support platform 2, passing around the counterweight 4 and the cantilever truck platform 3 in the middle.

[0027] During use, the lifting process is as follows: the motor in the hoisting system 7 rotates forward, causing the chain of the lifting chain 8 on the side of the cantilever platform 3 to shorten; the four lifting point pulleys 14 in the cantilever platform 3 drive the entire platform to rise; since the counterweight 4 is suspended on the outside of the frame 1 through the lifting chain 8 in the form of pulleys, the counterweight moves downward by the same distance.

[0028] The descent process: The motor in the hoisting system 7 reverses, causing the chain of the hoisting chain 8 on the side of the cantilever platform 3 to extend; the four lifting point pulleys 14 in the cantilever platform 3 drive the entire platform to descend; since the counterweight 4 is suspended on the outside of the frame 1 by the hoisting chain 8 in the form of a pulley, the counterweight moves upward by the same distance.

[0029] Leveling: When the cantilever truck platform 3 is raised or lowered to the designated position, the anti-fall pin on the anti-fall device 16 extends and inserts into the hole of the positioning plate on the frame 1; when the cantilever truck platform 3 needs to be raised or lowered, the anti-fall pin on the anti-fall device 16 retracts from the hole of the positioning plate on the frame 1.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
