The invention relates to the technical field of semitrailer supporting, in particular to a semitrailer supporting device which comprises a supporting seat, a hydraulic cylinder is fixed to the supporting seat, a supporting block is fixedly connected to a piston rod of the hydraulic cylinder, and the supporting seat is trapezoidal; an inclined rod is installed on the bottom face of the supporting block in a sliding mode, the inclined rod is located on one side of the hydraulic rod, an inclined block is fixed to the bottom end of the inclined rod, and the inclined block is parallel to one inclined face of the trapezoid; the supporting block is provided with a limiting device used for limiting sliding of the inclined rod. When the semitrailer supporting device is used, when a locking piece of one supporting device breaks down and a piston of a frame compression hydraulic cylinder moves downwards, an inclined block can rapidly abut against the inclined face of a base of the opposite supporting device, and an inclined rod, the opposite supporting device and the frame form a triangular structure, so that the supporting frame cannot continue to move downwards, and the semitrailer supporting device is convenient to use. Therefore, the technical problems mentioned in the background technology are effectively solved.
本发明涉及半挂车支撑技术领域,具体为一种半挂车支撑装置,包括支撑座,所述支撑座上固定有液压缸,所述液压缸的活塞杆上固定连接有支撑块,所述支撑座的形状为梯形;所述支撑块的底面上滑动安装有倾斜杆,所述倾斜杆位于所述液压杆的一侧,所述倾斜杆的底端固定有倾斜块,所述倾斜块平行于所述梯形的一个斜面;所述支撑块上设置有用于限制所述倾斜杆滑动的限位装置。该半挂车支撑装置在使用时,在其中一个支撑装置的锁止件发生故障时,车架压缩液压缸的活塞下移时,倾斜块会迅速抵在相对的支撑装置底座的倾斜面上,倾斜杆、相对的支撑装置和车架形成一三角形结构,从而使得支撑架不能继续下移,从而有效解决了背景技术提及的技术问题。
