The invention relates to the technical field of fully mechanized mining equipment, in particular to a production method of a pushing rod, a hydraulic support and a pushing rod. The invention provides a pushing rod, which includes a box body, tie bars and a reinforcement layer; the box body includes a first box body, the tie bars are welded in the first box body, and the reinforcement layer is filled between the tie bars and the first box body. The pushing bar provided by the present invention fills the reinforcement layer between the first box body and the tie bars, and the combination of the reinforcement layer and the tie bars can improve the rigidity and strength of the box body, thereby ensuring the overall stiffness and strength of the pushing bar, greatly The usage of steel is reduced, the utilization rate of steel is improved, and the cost of use is reduced. In addition, the tie bars can be of any shape, any size, any number, and welded in the box at any angle, and finally combined with the reinforcement layer poured into the box in the later stage, so there is no requirement for the welding quality of the tie bars , thus greatly saving the welding cost, and further reducing the production cost.
Description
technical field [0001] The invention relates to the technical field of fully mechanized mining equipment, in particular to a production method of a pushing rod, a hydraulic support and a pushing rod. Background technique [0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face. The hydraulic support includes top beams, cover beams, bases, connecting rods, pushing devices and other components, wherein the pushing devices are used to push the brackets and scraper conveyors. [0003] The pushing device is composed of a pushing rod, a pushing jack, a cross joint, a shear pin of the cross joint and the pushing rod, a cross joint and the hinge pin of the conveyor, a pushing rod and the hinge pin of the pushing jack. The force of the pushing device is complicated, and the rigidity and strength of the pushing rod are high. [0004] In the related art, the pushing bar is usually composed of a base plate, main ribs arranged oppositely o...
