Abstract

The invention relates to a continuous-walking type hydraulic pushing device. The continuous-walking type hydraulic pushing device comprises a pushing tray, a longitudinal hydraulic pushing cylinder, a lateral hydraulic pushing cylinder, a cylinder base and a cylinder supporting seat. The longitudinal hydraulic pushing cylinder and the lateral hydraulic pushing cylinder respectively comprise cylinder bodies and piston rods, and the pushing tray is welded on the piston rod of the longitudinal hydraulic pushing cylinder. The cylinder body of the longitudinal hydraulic pushing cylinder is vertically welded at the center of the cylinder body of the lateral hydraulic pushing cylinder, and can move to the right and to the left along with the lateral hydraulic pushing cylinder. The cylinder base is welded with the piston rods at two ends of the lateral hydraulic pushing cylinder. The lateral hydraulic pushing cylinder is arranged on the cylinder supporting seat, and can move to the right and to the left corresponding to the cylinder supporting seat. The longitudinal hydraulic pushing cylinder and the lateral hydraulic pushing cylinder are connected with a computer respectively and control to realize synchronically-coordinated actions through a computer control system. The continuous-walking type hydraulic pushing device is simple and reasonable in structure, convenient to process and manufacture, and low in production cost.

Description

technical field [0001] The invention relates to a hydraulic pushing device, in particular to a continuous walking hydraulic pushing device. Background technique [0002] In the field of modern engineering construction, hydraulic cylinder jacking devices are widely used. When the distance of pushing is relatively long, it is necessary to superimpose the strokes of the hydraulic cylinder for multiple pushing to complete the whole pushing construction task. Usually, when using the hydraulic cylinder push technology to push heavy objects, there must be a reaction force seat behind the cylinder. The superimposed construction of the push stroke needs to repeatedly dismantle the reaction seat, move it forward and install and fix it, which is cumbersome, time-consuming and labor-intensive. In addition, in the process of repeated installation and disassembly of the reaction force seat, it is easy to cause deformation and wear of the pushing track. The reaction force seat itself wil...
