A trailer carriage comprises two longitudinal beams and at least two cross beams located between the two longitudinal beams. The longitudinal beam comprises a side wall, an upper connecting wall and a lower connecting wall; the cross beam comprises an upper connecting plate, a lower connecting plate positioned below the upper connecting plate and opposite to the upper connecting plate, and an end plate positioned between the end parts of the upper connecting plate and the lower connecting plate; the end part of the cross beam is arranged between the upper connecting wall and the lower connecting wall of the longitudinal beam, the upper connecting plate leans against the lower part of the upper connecting wall, the lower connecting plate leans against the upper part of the lower connecting wall, and the end plate leans against the inner side of the side wall; the upper connecting plate is connected with the upper connecting wall through a first Haake bolt, the lower connecting plate is connected with the lower connecting wall through a second Haake bolt, and the end plate is connected with the side wall through a third Haake bolt. Due to the fact that the longitudinal beams and the transverse beams are fixed in a welding-free mode, the longitudinal beams and the transverse beams can be transported separately, the transportation cost is reduced, and meanwhile rapid assembly of the carriage is achieved through the Haake bolts.
一种挂车滑架,包括两根纵梁、以及至少两根位于两纵梁之间的横梁;纵梁包括侧壁、上连接壁、下连接壁;横梁包括上连接板、位于上连接板下方且与上连接板相对的下连接板、位于上连接板和下连接板端部之间的端板;横梁的端部置于纵梁的上连接壁和下连接壁之间,上连接板贴靠在上连接壁下方、下连接板贴靠在下连接壁上方、端板贴靠在侧壁的内侧;上连接板与上连接壁通过第一哈克螺栓连接、下连接板与下连接壁通过第二哈克螺栓连接、端板与侧壁通过第三哈克螺栓连接。本发明由于采用免焊接的方式固定纵梁和横梁,使得纵梁和横梁能够分开运输,降低了运输成本,同时,利用哈克螺栓实现滑架的快速组装。
