Abstract

The invention discloses welding of an upper connecting shaft. The welding of the upper connecting shaft is characterized in that connecting bolts are respectively arranged at both ends of the connecting shaft, a bracket sleeve is arranged on a middle part of the connecting shaft, and reinforcing ribs are respectively arranged between both sides of the bracket sleeve and the connecting shaft. Through the above arrangement, round steel is welded with a seamless tube, and the welding of the upper connecting shaft is used in connection of a triangular frame and a hydraulic oil cylinder of a self-discharging freight car, thereby avoiding the situation that the service life of other parts is affected due to breakage of the upper connecting shaft.

Description

technical field [0001] The invention relates to a connecting device for connecting a tripod and an oil cylinder on a dump truck, in particular to welding of an upper connecting shaft of a tripod assembly. Background technique [0002] The connection device welded by the two triangular plates on the dump truck is a main force-bearing part in the entire lifting mechanism. The traditional upper connection shaft is welded with castings, and the castings have defects such as air holes and sand holes. , There will be a phenomenon of fracture during use, which affects the service life of other parts. Contents of the invention [0003] The object of the present invention is to provide a kind of welding of the upper connecting shaft connecting the tripod of the dump truck and the oil cylinder. [0004] In order to achieve the above object, the present invention is provided with connecting bolts at both ends of the connecting shaft, the bracket is sleeved in the middle of the conne...
