[0002] In the dump truck modification industry, after the cylinder used to lift the cargo compartment is fixed and installed through the cylinder support, it needs to be tilted backward more than 30 degrees, and then the cargo compartment is lifted by the square wood on the subframe, and finally transferred to the hydraulic loading station.

[0003] When the hydraulic loading station is in progress, the hydraulic oil pipe is arranged from the middle of the oil cylinder support. The oil cylinder must be lifted when driving, and the oil pipe joint can be installed in a vertical form. Only in this way can the gap between the oil pipe joint and the components at each end of the cab be observed, and the height of the oil pipe can be controlled. This method of installing the oil pipe has the problem of affecting the production cycle. Another problem is that after the oil cylinder used to lift the cargo compartment is installed and transported, the inertia generated by the vehicle braking causes the oil cylinder to tilt forward, thereby breaking the rear window glass of the cab. This situation has occurred many times, causing considerable losses to the company and individuals.

[0004] like Figure 1 The connection structure between the oil cylinder and the oil cylinder support shown is as follows: the two lower hinge shafts 2 symmetrically arranged on the oil cylinder 1 are inserted into the axial holes of the two sets of oil cylinder supports, and the oil cylinder support is fixed to the front end of the frame subbeam by M16*50 bolts; the oil cylinder support is mainly composed of a base 3 and a shaft sleeve 4 fixed on the base.
