Its structure is easy to weld, lightweight, reliable, and compact. It can reduce the overall size of the wet spraying trolley and avoid the problems of difficult maintenance and assembly caused by the dispersed assembly design. At the same time, it can reduce the overall weight of the engineering vehicle and eliminate the need for maintenance personnel to change maintenance positions multiple times. It can effectively solve the problems in the background art.

Three right center frame bottom cross braces are evenly distributed on the bottom inner side of the right center frame outer beam. A liquid pump support, a water pump base, and a water drum base are respectively fixed to the top of the three right center frame bottom cross braces.

[0006] Furthermore, it also includes a water tank frame stiffener plate, which is fixed to the top of the outer beam of the right middle frame, and a water tank baffle is fixed to the top of the water tank frame stiffener plate.

[0007] Furthermore, it also includes a second outer beam of the right central frame, which is fixed to the top of the vertical beam of the right central frame, and the top of the second outer beam of the right central frame is fixed with a right central frame deck.

[0011] 1. Its structure is easy to weld, lightweight, reliable, and compact, which can reduce the overall size of the wet spraying trolley.

[0012] 2. It can accommodate the installation of hydraulic radiators, auxiliary valve blocks, liquid pumps, quick-setting agent hose pumps, cleaning water pumps, water hose reels, quick-setting agent tanks, silencers, and side doors on tunnel wet spraying trolleys, avoiding the difficulties in maintenance and assembly caused by decentralized assembly design. At the same time, it can reduce the overall weight of the engineering vehicle and eliminate the need for maintenance personnel to change maintenance positions multiple times.
