[0055] A support frame 3, the support frame 3 is fixedly connected in the vehicle body 1;

[0056] A limiting component is installed between the supporting frame 3 and the cover plate 8 .

[0057] The main function of the limiting component is to fix the opened cover 8 to prevent the cover 8 from falling suddenly and causing a safety accident; the supporting frame 3 is equipped with lifting and transportation equipment, which cooperates with the working channel opening 9 to facilitate the transportation of materials on and under the vehicle and improve the working efficiency.

[0058] Further optimization scheme, the limiting components include:

[0059] A positioning groove 5, the positioning groove 5 is vertically slidably connected to the first column 4 of the support frame 3;

[0060] The first limiting groove 12 is provided at the bottom of the positioning groove body 5 and is adapted to the thickness of the cover plate 8 .

[0061] The positioning groove body 5 is mainly suitable for the cover plate 8 close to the first column 4; after the cover plate 8 close to the first column 4 is opened, the first limiting groove 12 is made to correspond to the cover plate 8 by sliding the positioning groove body 5, and the cover plate 8 is confined in the first limiting groove 12.

[0062] Further optimization plans also include:

[0063] A limit block (not shown in the figure), the limit block is fixedly connected to the first column 4, and the positioning groove 5 is located above the limit block;

[0064] The positioning pin and the positioning slot 5 are limited on the first column 4 by the positioning pin.

[0065] The limit block corresponds to the cover plate 8 in the open state; when the positioning slot 5 limits the cover plate 8, the positioning slot 5 just contacts the top of the limit block; when the cover plate 8 needs to be closed, the positioning slot 5 is first moved upward to disengage the cover plate 8 from the first limit slot 12, and the positioning slot 5 is limited on the first column 4 by the positioning pin.

[0066] Further optimization scheme, the limiting components include:

[0067] A rotating trough body 7, wherein the rotating trough body 7 is rotatably connected between adjacent first upright posts 4 on the supporting frame 3;

[0068] The second limiting groove 16 is provided at the bottom of the rotating groove body 7 and is adapted to the thickness of the cover plate 8 .

[0069] The rotating groove body 7 is mainly suitable for the cover plate 8 located between adjacent first columns 4; after the cover plate 8 is opened, the rotating groove body 7 is manually rotated to make the second limiting groove 16 correspond to the cover plate 8 and limit the cover plate 8 in the second limiting groove 16.

[0070] Further optimization plans also include:

[0071] The second column 6 is vertically fixed between adjacent first columns 4 , and the rotating groove body 7 is rotatably connected to the top of the second column 6 .

[0073] Further optimization plans also include:

[0074] The spring has two ends respectively connected to the side wall of the second column 6 and one end of the rotating groove body 7 close to the cover plate 8.

[0075] An inclined surface is arranged below one end of the rotating groove body 7 close to the cover plate 8. When the cover plate 8 is manually pulled open and contacts the inclined surface, the rotating groove body 7 is pushed to rotate synchronously with the second limiting groove 16 and overcome the spring rebound force. When the cover plate 8 enters the second limiting groove 16, the rotating groove body 7 is buckled on the cover plate 8 through the second limiting groove 16 under the action of the spring rebound force, and the cover plate 8 is restricted in the second limiting groove 16, completing the opening state of the cover plate 8. After the cover plate 8 is restricted by the second limiting groove 16 on the rotating groove body 7, under the action of the spring, the cover plate 8 and the rotating groove body 7 are in abutment relationship, preventing the rotating groove body 7 from being easily opened, causing the cover plate 8 to close suddenly.

[0077] The limiting plate 14 is fixedly connected to one end of the rotating trough 7 away from the cover plate 8 , and is arranged corresponding to the side of the second column 6 away from the cover plate 8 .

[0078] The main function of the limit plate 14 is to limit the rotation angle of the rotating groove body 7. It is only necessary to ensure that the rotation angle of the rotating groove body 7 does not affect the opening and closing of the cover plate 8, so that the end of the rotating groove body 7 provided with the second limit groove 16 does not invade the equipment space behind the column.

[0079] Further optimization plans also include:

[0080] The baffle 13 is fixedly connected in the working channel opening 9 and is arranged corresponding to the side of the cover plate 8.

[0081] The main function of the baffle 13 is to limit and support the cover plate 8 so that the top surface of the closed cover plate 8 is flush with the inner floor of the vehicle body 1, which is convenient for operators to move around.

[0082] Further optimization plans also include:

[0083] The support rod 15 has two ends connected between the cover plate 8 and the working channel opening 9 respectively.

[0084] The support rod 15 can be a pneumatic or hydraulic telescopic rod, so as to save more effort when the cover plate 8 is lifted.

[0085] On the whole, the present application enables operators to quickly inspect and repair the working units on and under the vehicle, and perform through operations, which greatly facilitates the control, layout and installation of the working units, and enables comprehensive inspection and maintenance of the working units without disassembling the working units and the vehicle body structure.
