The flap test roadblock machine is large in size and complex in structure. Part of the impact force is limited by the rotating shaft, and the impact resistance is insufficient. The complex connection structure increases the production and installation costs. The lifting test roadblock machine using scissor lifting technology is also limited by the rotating shaft and has insufficient impact resistance. The lifting test roadblock machine using scissor lifting technology is large in size, complex in structure, and high in production cost. The movable structure and installation shell of the two roadblock machines are welded into a whole, and repair and maintenance are relatively cumbersome. Replacement requires digging out the entire roadblock body, which increases the installation cost of the roadblock machine. Summary of the invention

A hydraulic cylinder 5 is fixed to the center of the bottom plate of the movable groove of the outer shell box 1 through a fixing frame 4. The top of the piston rod of the hydraulic cylinder 5 is connected to the inner wall of the movable wall 2 through a balance adjustment mechanism 3, and the balance adjustment mechanism 3 includes a fixed bracket 301 connected to the piston rod of the hydraulic cylinder, and suspension rods 302 are symmetrically arranged at both ends of the fixed bracket 301. The upper end of the suspension rod 302 is threadedly connected to the fixed bracket 301, and the lower end of the suspension rod 302 is connected to the lifting ring 303 through a rotating shaft, and the lower end of the lifting ring 303 is connected to the inner wall of the movable wall 2 through a screw, and the lifting ring 303 is a forward and backward swinging rotating shaft structure.

[0025] The height of the hydraulic cylinder and each side of the movable wall can be adjusted through the balance adjustment mechanism to achieve balance on each side, thus solving the problem of left and right balance of a single cylinder support. The balance adjustment mechanism and the movable wall are connected by a ring-type universal structure. When the movable wall is hit and deviates from the center, the hydraulic cylinder withstands a small outward pulling force through the ring, which will not cause the hydraulic cylinder to deform, thus protecting the hydraulic cylinder and allowing the product to operate normally after being hit.
