[0012] As a preferred technical solution of this utility model, guide wheel brackets are installed at both ends on the same side of the welded frame assembly, and guide wheels are provided on the guide wheel brackets. The guide wheels cooperate with the guide rails on the ground push chain and the drying chain.

[0013] As a preferred technical solution of this utility model, anti-collision bars are installed at both ends of the other side of the welded frame assembly to ensure a safe distance of the vehicle body perpendicular to the direction of movement.

[0014] As a preferred technical solution of this utility model, an anti-collision buckle is provided at the middle position of one end of the welded frame assembly. The anti-collision buckle is a buckle with a flared opening shape, which is used to ensure a safe distance of the vehicle body in the direction of movement.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 2 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-2 This utility model provides a technical solution: a ground vehicle-type body carrier, including a welded frame assembly 1, universal wheels 2, a common support block 3 and an adjustable support component 4;

[0023] Among them, the welded frame assembly 1 is welded from steel profiles and forms the main load-bearing structure of the trolley. In order to eliminate welding internal stress and ensure that it does not deform under high temperature drying environment, the welded frame assembly is subjected to overall heat treatment after welding. Specifically, it includes annealing to eliminate stress and tempering to improve its high temperature stability. The frame surface is coated with anti-corrosion coating to prevent the frame from deforming when passing through the drying oven.

[0024] The omnidirectional wheels 2 are evenly distributed at the lower end of the welded frame assembly 1 to ensure that the trolley can move and turn flexibly. The wheel core, bearing and mounting bracket of the omnidirectional wheels 2 are made of stainless steel to prevent corrosion when passing through humid areas.

[0025] There are two common support blocks 3, which are set at the upper end of the welded frame assembly 1. The two common support blocks 3 have different base heights and are used to support the reference positioning points common to different vehicle models.

[0026] Three adjustable support components 4 are fixed to the upper end of the welded frame assembly 1. The three adjustable support components 4 are fixed to the welded frame assembly 1 at different base heights, which makes it convenient to increase the upper limit of the support height.

[0027] The adjustable support assembly 4 includes a support arm 41, a positioning pin 42, a stud 43, and an adjusting nut 44. The support arm 41 is welded to the welded frame assembly 1. Positioning pins 42 are symmetrically arranged on both sides of the upper end of the support arm 41. The lower end of the positioning pin 42 is integrally connected to the stud 43. The lower end of the stud 43 passes through the support arm 41, and the adjusting nut 44 is threadedly connected to the outer side of the stud 43. When different vehicle bodies need to be supported, the support height of the positioning pin 42 can be changed by rotating the adjusting nut 44. The support height of the vehicle body can be adjusted according to the wheelbase and track of different vehicle models.

[0028] To ensure that the trolley-mounted mechanized conveyor section can be accurately aligned and run smoothly, guide wheel brackets 5 are installed at both ends on the same side of the welded frame assembly 1. Guide wheels 6 are set on the guide wheel brackets 5. The guide wheels 6 cooperate with the guide rails on the ground push chain, drying chain and other equipment. Similar to the universal walking wheel 2, the guide wheels 6 are made of stainless steel and have a high temperature resistant wheel surface.

[0029] In this embodiment, anti-collision bars 7 are installed at both ends of the other side of the welded frame assembly 1 to ensure a safe distance between the vehicle body and the direction of movement.

[0030] Furthermore, there is an anti-collision buckle 8 at the middle position of one end of the welded frame assembly 1. The anti-collision buckle 8 is a buckle with a flared opening shape, which is used to ensure a safe distance of the vehicle body in the direction of movement.

[0031] Furthermore, a number plate 9 is installed on one side of the welded frame assembly 1 to identify the number of each car and to ensure precise parking.

[0032] In use: When it is necessary to switch vehicle models, the operator uses a special tool to adjust the height of the positioning pin 42 according to the predetermined vehicle model parameters and fix it with the adjusting nut 44; the trolley carries the vehicle body at the electrophoresis docking point, is pushed by the ground push chain, and is guided by the guide wheel 6, passing through the high temperature drying oven, cooling zone, paint booth, etc. in sequence. Throughout the process, its high temperature resistance and corrosion resistance ensure the reliability of operation.

[0033] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model. The scope of the utility model is defined by the appended claims and their equivalents.
