The invention discloses a self-locking type hydraulic supporting mechanism, and belongs to the technical field of transport trailer structures, the self-locking type hydraulic supporting mechanism specifically comprises a trailer, a hydraulic cylinder and an anti-overturning structure, and the trailer is provided with an air cylinder and a vehicle-mounted storage battery; the hydraulic cylinder is connected with a vehicle-mounted storage battery, the hydraulic cylinder replaces a front side supporting leg of the trailer, a cylinder body a of the hydraulic cylinder is installed on the front side of the trailer, and a piston rod a of the hydraulic cylinder points to the ground. The anti-overturning structure is arranged between the cylinder body a and the piston rod a and used for preventing the piston rod a from retracting inwards, the self-locking type hydraulic supporting mechanism can be remotely controlled to automatically ascend and descend (or can be operated in a cab) under the condition of power failure and fuel cut, a traction disc can be separated from a trailer, and disengaging and connecting of the tractor and the trailer can be completed in about one minute. And the labor intensity and the unhooking time are greatly reduced.

    本发明公开了一种自锁式液压支撑机构,属于运输挂车结构技术领域,具体包括挂车、液压缸和防倾覆结构,所述挂车配备有储气筒和车载电瓶;所述液压缸连接车载电瓶,所述液压缸替代所述挂车的前侧支腿,所述液压缸的缸体a安装于所述挂车的前侧,所述液压缸的活塞杆a指向地面;所述防倾覆结构设置于所述缸体a和活塞杆a之间,用于防止断电断油情况下所述活塞杆a内缩自锁式液压支撑机构是可以遥控自动升降(也可以在驾驶室操作),就可以将牵引盘与挂车分离,约1分钟就可以完成牵引车和挂车的脱挂和连接,大大降低了劳动强度和脱挂的时间。
