A structure and the manufacturing method for friction parts on concrete pump

Abstract

The present invention relates to a sliding motion structure for a concrete pump that can reduce the extent of abrasion and solve the problem of high maintenance expenses resulting from frequency replacement of the sliding motion structure by fabricating friction areas with a plurality of wear-resistant friction blocks, and to a manufacturing method thereof. Also, the sliding motion structure and the manufacturing method thereof can also prevent the internal wall surfaces of the inlet ports and outputs, through which concrete is transferred, from being worn out and prevent the external end of the connecting pipe from being worn out partially. The sliding motion structure of the present research includes a plane fixed member having a wear plate, a pair of coupling tubes, first friction members, and a second friction member; and a ring-shaped movable member having a ring-shaped connecting pipe and a third friction member which is formed of tungsten carbide and connected to the first and second friction members tightly along the ends of the connecting pipe in the same length.

Description

Technical field [0001] The present invention relates to a concrete pump, in particular to a sliding structure used in a concrete pump and a method for manufacturing it, wherein the sliding structure can be manufactured with a plurality of wear-resistant friction blocks in the friction area of ​​the sliding structure, and Solve the problem of high maintenance cost due to frequent replacement, and prevent the inner wall of the inlet / outlet hole of the concrete from being worn out and the outer end of the coupling pipe from being unevenly worn, thereby reducing their wear rate. Background technique [0002] figure 1 It is a perspective view of an example of a traditional concrete pump. As shown in the figure, there are a pair of concrete cylinders 12a and 12b. The concrete pistons 11a and 11b are installed in the pair of concrete cylinders 12a and 12b, respectively. 13 is connected to the outlet holes of the concrete cylinders 12a and 12b, and the inlet holes 13a and 13b of the fi...
