Document Type and Number:
WIPO Patent Application WO/2018/000950
Kind Code:
A1
Abstract:
Disclosed are an arm structure and a track bed line construction and maintenance apparatus using the arm structure, the arm structure comprising a main arm assembly (1) and an auxiliary assembly (2), wherein the main arm assembly (1) comprises a first force-bearing arm (11), the first force-bearing arm (11) being in the form of a bended structure, hinged to a first end of a connecting base (3) and pitching relative to the connecting base (3); and the auxiliary assembly (2) comprises a second force-bearing arm (21), the second force-bearing arm (21), being in the form of a bended structure, hinged to first force-bearing arm (11) at one end thereof and pitching relative to the first force-bearing arm (11), and wherein the direction the first force-bearing arm (11) is bent is opposite to that of the second force-bearing arm (21). The design of the bended structures of the main arm assembly (1) and the auxiliary assembly (2) and an arrangement of a set of hydraulic cylinders enable the main arm assembly (1) and the auxiliary assembly (2) to have a larger angular movement region and more postures when operating, and the occupied space required for storing the main arm assembly (1) and the auxiliary assembly (2) is reduced.
