Description

Technical Field

[0001] The utility model relates to the technical field of automotive auxiliary tools, and particularly relates to a lifting tool for a commercial vehicle frame. Background Art

[0002] A lifting tool refers to a device for lifting heavy objects during the process of a hoisting machine. During the production process of commercial vehicles, since a large number of workpieces need to be assembled and welded together, the lifting tool becomes particularly important, which directly affects the processing volume, production efficiency, manufacturing cost, etc. Using a lifting tool can improve production efficiency, reduce production costs, and reduce labor intensity, etc. Currently, in the processing process of commercial vehicles, generally, workers manually lift the vehicle frame onto the tooling fixture, and at least four people are required to carry one vehicle frame, resulting in high labor costs and time-consuming and laborious work. There is no lifting tool in the prior art that is adapted to this commercial vehicle frame. Summary of the Invention

[0003] To solve the deficiencies existing in the prior art, the utility model provides a lifting tool for a commercial vehicle frame, which has the advantage of high working efficiency.

[0004] The above-mentioned invention object of the utility model is achieved through the following technical solutions:

[0005] The utility model provides a lifting tool for a commercial vehicle frame, including:

[0006] A frame body, on which a plurality of mounting seats are fixedly connected, and a first lifting ring is provided at the upper part of the mounting seat;

[0007] A lifting part, a plurality of which are provided, and the lifting part is fixedly connected with the frame body;

[0008] A handrail, which is fixedly connected to one side of the frame body;

[0009] And a lifting chain, a plurality of which are provided, and the lifting chain is detachably connected with the first lifting ring.

[0010] By adopting the above technical solutions, during use, the lifting tool is connected with the hoisting equipment through the lifting chain, and the lifting tool is moved to a specified position above the vehicle frame. The operator controls the lifting part of the lifting tool to reach the established position of the vehicle frame through the handrail, starts the hoisting equipment, and the vehicle frame can be lifted. When it is transported to the material vehicle on the vehicle frame storage rack, the operator controls the lifting part to disengage from the vehicle frame through the handrail, and the hoisting equipment moves the lifting tool to the original position, and the hoisting action is completed.

[0011] Furthermore, the frame body is fixedly connected by two long frames and two short frames. The two long frames are arranged in parallel with each other, and the two short frames are arranged in parallel with each other. The frame body further includes a cross beam and a vertical beam. The two ends of the cross beam are respectively fixed in the middle of the two long frames, and the two ends of the vertical beam are respectively fixed in the middle of the two short frames.

[0012] By adopting the above technical solution, the frame body is formed with a basic frame in a structure similar to a "field" shape, which is adapted to the frame body of a commercial vehicle. Moreover, the arrangement of the cross beams and vertical beams increases the load-bearing capacity of the spreader frame and enhances the stability of the spreader.

[0013] Further, the long frame is composed of a first long frame, a second long frame and a connecting frame. The first long frame and the second long frame are arranged in parallel. The two ends of the connecting frame are respectively vertically connected to the first long frame and the second long frame. The short frame includes a first short frame and a second short frame, and the length of the first short frame is less than that of the second short frame.

[0014] By adopting the above technical solution, the frame body has a structure similar to a "convex" shape, with a narrow width at one end. When operating the spreader to hoist the vehicle frame, it can avoid interference between the front end and the vehicle frame, and is adapted to the structure of the vehicle frame.

[0015] Further, the mounting seat includes a base, a connecting plate and two reinforcing plates. The base is fixedly connected to the frame body through two U-shaped connecting pieces. The connecting plate is perpendicular to the base, and the connecting plate and the base are fixedly connected through two reinforcing plates. The first lifting ring is opened at the upper part of the connecting plate.

[0016] By adopting the above technical solution, the mounting seat is firmly fixed on the frame body and forms a connecting part for the lifting chain, which is convenient for connecting with the lifting chain.

[0017] Further, there are four lifting parts. Two lifting parts are symmetrically arranged at both ends of a short frame respectively, and two lifting parts are symmetrically arranged on the two long frames respectively.

[0018] By adopting the above technical solution, the lifting parts are evenly distributed on the frame body, and the lifting force on the vehicle frame is uniform, which can avoid adverse conditions such as the vehicle frame tilting due to uneven stress.

[0019] Further, the lifting part is an L-shaped bracket, and a baffle is arranged at the front end of the L-shaped bracket.

[0020] By adopting the above technical solution, the long end of the L-shaped bracket is fixed on the frame body, and its short end abuts against the vehicle frame to support the vehicle frame to be lifted. The baffle can prevent the vehicle frame from detaching from the lifting part and increase the safety of the spreader.

[0021] Further, there are two handrails, and the two handrails are symmetrically arranged on the outer sides of the long frames.

[0022] By adopting the above technical solution, the direction of the spreader can be controlled on either side of the vehicle frame, with high flexibility.

[0023] Further, there are four lifting chains. Both ends of the lifting chains are provided with lifting buckles. The lifting buckle at one end of the lifting chain close to the mounting seat is detachably connected to the first lifting ring, and the lifting buckle at the end of the lifting chain far from the mounting seat is connected with a second lifting ring.

[0024] By adopting the above technical solution, the other ends of the suspension chains converge at the second hanging ring, and the lifting equipment can lift the lifting tool through the second hanging ring.

[0025] In summary, the utility model includes at least one of the following beneficial technical effects: for the commercial vehicle frame lifting tool of the utility model, the lifting part is controlled by the armrest to lift the frame, the suspension chains transmit the pulling force to the frame body, and the pulling force is evenly applied to the frame body, so that the frame can be stably lifted. The baffle arranged on the lifting part prevents the frame from falling off, and the action process is stable, efficient, labor-saving and time-saving. Description of the Drawings
