Description

Technical Field

[0001] This utility model relates to the field of vehicle assembly technology, and in particular to a lifting device suitable for assembling the upper support of a gas spring with a vehicle frame. Background Technology

[0002] Currently, a certain vehicle model uses a gas spring suspension system. Because the gas spring supports are made of cast iron, they are manually moved and assembled onto the vehicle frame. This method is inconvenient due to their considerable weight (approximately 50 kg), and there is currently no dedicated lifting equipment available. During assembly, two assembly workers are required to move the upper gas spring support from the storage rack to the vehicle frame, adjust the mounting holes, and then bolt it onto the frame. The entire installation process is inefficient and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a lifting device suitable for assembling the upper support of a gas spring with a vehicle frame.

[0004] This utility model is achieved using the following technical solution:

[0005] A lifting device suitable for assembling an upper support of a gas spring with a vehicle frame includes a lifting device body; the lifting device body has an inverted U-shaped structure, a lifting hole is provided at the top of the lifting device body, and multiple positioning pins are provided at the bottom of the lifting device body, with the lifting device body and the positioning pins being arranged perpendicularly.

[0006] Furthermore, the lifting device body is an integral plate structure.

[0007] Furthermore, sloping shoulders are symmetrically arranged on both sides of the lifting hole on the top of the lifting device body, and the sloping shoulders are inclined downward from the center of the lifting hole.

[0008] Furthermore, the sloping shoulder is provided with weight-reducing holes.

[0009] Furthermore, the lifting device body and the positioning pin are detachably connected.

[0010] Compared with the prior art, the present invention has the following beneficial technical effects:

[0011] This invention can replace manual labor in moving and positioning the upper support of the gas spring, thereby completing the assembly of the upper support of the gas spring with the frame, improving work efficiency and reducing labor intensity. Attached Figure Description

[0015] In the diagram, 1 is the lifting device body; 2 is the positioning pin; 3 is the lifting hole; 4 is the sloping shoulder; and 5 is the weight reduction hole. Detailed Implementation

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise explicitly specified and limited, the embodiments and features described in the embodiments of this application can be combined with each other. In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-2 As shown: A lifting device suitable for assembling a gas spring upper support with a vehicle frame includes a lifting device body 1; the lifting device body 1 has an inverted U-shaped structure, a lifting hole 3 is provided at the top of the lifting device body 1, and a plurality of positioning pins 2 are provided at the bottom of the lifting device body 1, with the lifting device body 1 and the positioning pins 2 arranged perpendicularly. Preferably, there are two positioning pins 2.

[0018] The lifting device body 1 is a one-piece plate structure. Symmetrical sloping shoulders 4 are located on both sides of the lifting hole 3 at the top of the lifting device body 1, with the sloping shoulders 4 tilting downwards from the center of the lifting hole 3. Weight-reducing holes 5 are provided on the sloping shoulders 4. The lifting device achieves lightweight design while maintaining sufficient lifting strength.

[0019] The lifting device body 1 and the positioning pin 2 are detachable.

[0020] Working principle: Fix the lifting device to the hook of the overhead crane in the workshop via the lifting lug; insert the positioning pin 2 into the mounting hole above the upper support of the gas spring; start the overhead crane and use the lifting device to move the upper support of the gas spring to the top of the frame; the user makes final adjustments and alignments to the upper support of the gas spring, and then slowly lowers the upper support of the gas spring onto the frame; remove the lifting device and use bolts to install the upper support of the gas spring onto the frame.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
