Description

Technical Field

[0001] The invention relates to the technical field of liquid tank trucks, and in particular to a liquid tank truck, a tank body and a method for manufacturing the tank body. Background Art

[0002] With the rapid development of the national economy, there is an increasing demand for tank trucks for long-distance transportation of various liquids, but the manufacturing process still remains in the traditional and backward stage. In order to make a round tank, the traditional process is to first splice a very large blank according to the unfolded size of the material. This blank is too large to be automated or the cost is extremely high during the transportation, flipping, and welding process; during the process of rolling or wrapping the blank, the blank is too large and the positioning accuracy cannot be adjusted, resulting in a large gap between the arc and the theoretical size, and the splicing seam is misplaced and ugly; when wrapping or rolling the tank body and assembling it with the partition, the partition needs to be inserted from the two ends. Due to the extremely poor accuracy, the gap between the partition can only be enlarged, increasing the welding workload; when welding the partition, people have to climb into the tank body and work in a limited space, which poses a great safety hazard, and related cases of loss of life are not uncommon. After visiting, investigating and searching, it is found that the current national vehicle-mounted tank industry is manually crawling in for welding, and it is impossible to achieve partial or most automated welding. Summary of the invention

[0003] The present invention provides a liquid tank truck, a tank body and a method for manufacturing the tank body, which are used to solve the problems in the prior art that the tank body cannot be assembled and welded, and the welding of the partition is highly dangerous.

[0004] In order to solve the above technical problems, the present invention proposes a liquid tank body, which includes a bottom plate, a left panel and a right panel with the same left-right symmetrical structure, a front panel and a rear panel with the same front-rear symmetrical structure, and a top plate, wherein the bottom plate, the left panel, the right panel, the front panel, the rear panel and the top plate are welded into a tank body.

[0005] Furthermore, a partition is provided in the tank body, and a manhole and a manhole cover are provided on the top plate.

[0006] A liquid tank truck comprises the tank body as described above.

[0007] The present invention also proposes a tank manufacturing method, comprising the following steps: S1. Place the base plate 1 on the workpiece and fix it; S2. First weld the partition 7 on the bottom plate 1; S3. Welding the left panel 2 and the right panel 3; S4. Welding the front panel 6 and the rear panel 5; S5. Finally, the top plate 4 is welded to form a tank body.

[0008] Furthermore, the welding is performed by a welding robot.

[0009] Compared with the prior art, the present invention has the following advantages: 1. Change the overall rounding or rolling of the cylinder of the tank into a multi-piece splicing type to simplify and standardize the parts forming process of the tank, which is conducive to subsequent automated production.

[0010] 2. Due to the design of the split molding process, the traditional large-scale cutting machine tools and the large area of ​​welding operation space can be discarded in the subsequent production, saving production space.

[0011] 4. As the split design allows for assembly operations, the welding of the partition becomes simpler, making welding automated, which completely changes the traditional situation where operators are trapped inside the tank for welding operations. Assembly line production will become a practical option.

[0012] 5. The split design greatly improves production efficiency and product quality, and greatly reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Liquid tank truck embodiment: The liquid tank truck includes a liquid tank truck chassis and a tank body supported on the liquid tank truck chassis.

[0018] The present invention aims to improve the structure and production method of the tank body, so the tank truck chassis and other structures on the tank truck can adopt the structures in the prior art, which will not be described in detail here.

[0019] Tank Example: Please refer to Figure 1 A tank body comprises a bottom plate 1, a left panel 2 and a right panel 3 with the same left-right symmetrical structure, a front panel 6 and a rear panel 5 with the same front-back symmetrical structure, and a top plate 4. The bottom plate 1, the left panel 2, the right panel 3, the front panel 6, the rear panel 5 and the top plate 4 are welded into the tank body.

[0020] Furthermore, a partition plate 7 is provided in the tank body, and a manhole and a manhole cover are provided on the top plate 4.

[0021] During production, the tank body is divided into six independent plates, namely the bottom plate 1, the left side plate 2, the right side plate 3, the front side plate 6, the rear side plate 5 and the top plate 4, which are spliced ​​and assembled in sequence on the tooling. Each plate is provided with concave ribs to increase the strength of the plate.

[0022] Tank body manufacturing method embodiment: A tank body manufacturing method comprises the following steps: S1. Place the base plate 1 on the workpiece and fix it; S2. First weld the partition 7 on the bottom plate 1; S3. Welding the left panel 2 and the right panel 3; S4. Welding the front panel 6 and the rear panel 5; S5. Finally, the top plate 4 is welded to form a tank body.

[0023] Furthermore, the welding is performed by a welding robot.

[0024] After the tank body is divided into six plates, each plate is cut by plasma gas and then spliced ​​by a welding robot to form a tank body. The automatic welding method reduces the number of manual welds, reduces manufacturing errors, improves weld accuracy, and reduces labor intensity.

[0025] The partition plate 7 is first welded to the bottom plate 1, which avoids the phenomenon that workers previously weld inside the cylinder, thereby improving the safety of workers during welding.

[0026] In summary, the tank truck and its tank body of the present invention, through the tank body manufacturing method of splicing six plates, avoids the previous use of a whole plate to roll the cylinder body, can effectively improve the accuracy, and avoid the weld dislocation, more beautiful. At the same time, the spliced ​​tank body achieves the purpose of not easy to deform, ensuring the quality of the weld, reducing the workload of manual welding, improving production efficiency, promoting mechanization development and reducing costs.
