Detailed implementation manners

[0020] Existing fire truck carriages are generally low-carbon steel welded carriages, relying on arc welding or CO2 gas shielded welding, and need to be processed through multiple processes such as material cutting, bending, assembly, welding, straightening, and anti-corrosion treatment in sequence.

[0027] In addition, if terms such as "first", "second", etc. are used only for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0028] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0029] The overall structure, working principle and technical effects achieved of the lap - type fire truck compartment and the fire truck provided by the present invention will be introduced in detail below through embodiments in conjunction with the drawings.

After lap - jointing, they are integrally lap - jointed and installed on the subframe 110. In this way, the component assembly and manufacturing are carried out simultaneously, the production process can be shortened, thereby improving production efficiency and reducing processes.

[0035] It should be noted that the floor frame assembly 120 is the bottom frame structure of the fire truck compartment 100 formed by overlapping profiles with corner codes, and is generally used to carry the bottom plate of the fire truck compartment 100. The left frame assembly 130 is the left frame structure of the fire truck compartment 100 formed by overlapping profiles with corner codes, and is generally used to connect and support the left side plate of the fire truck compartment 100. The right frame assembly 140 is the right frame structure of the fire truck compartment 100 formed by overlapping profiles with corner codes, and is generally used to connect and support the right side plate of the fire truck compartment 100. The front frame assembly 150 is the front frame structure of the fire truck compartment 100 formed by overlapping profiles with corner codes, and is generally used to connect and support the front side plate of the fire truck compartment 100. The rear frame assembly 160 is the rear frame structure of the fire truck compartment 100 formed by overlapping profiles with corner codes, and is generally used to connect and support the rear side plate of the fire truck compartment 100 and install the rear rolling door.
