T-shaped integral-rotation adjustable cantilever base

Abstract

The invention relates to a T-shaped integral-rotation adjustable cantilever base. The T-shaped integral-rotation adjustable cantilever base comprises a base body which is fixed to a strut and installed vertically, and horizontal connecting single lugs are arranged on the side face of the base body. Opening holes are formed in the middles of the connecting single lugs, the connecting single lugs the and lower connecting rings on the upper portions of the connecting single lugs are fixed, the lower connecting rings are provided with opening holes corresponding to the connecting single lugs, andvertical bearing assemblies is are arranged in the opening holes. The bearing assemblies and the lower connecting rings are fixed and are connected with boss rotary fixing shafts, and cantilever brackets are mounted on the boss rotary fixing shafts through the end portions. According to the T-shaped integral-rotation adjustable cantilever base, the free rotation of the boss rotary fixing shafts isrealized through rolling bearings, the horizontal free rotation of the cantilever brackets is further driven by the close connection between square structures of the lower parts of the boss rotary fixing shaft and square holes of the cantilever brackets, the horizontal free rotation of contact lines and carrier cables of the end portions of the cantilever brackets is further driven, and the horizontal lateral movement function of flexible mobile contact nets is further realized.

Description

technical field [0001] The invention belongs to the technical field of electrified railway catenary, and in particular relates to a T-shaped integrally rotatable and adjustable wrist arm base. Background technique [0002] With the continuous construction of railway freight lines, more and more railway cargo loading and unloading lines have been put into use. The loading and unloading operations of busy and efficient railway freight handling lines require that freight trains can arrive and depart quickly. Traditional railway cargo loading and unloading lines use diesel locomotives to perform machine adjustment operations before and after cargo loading and unloading. This method is complicated and time-consuming, and it is difficult to meet the needs of efficient modern railway cargo loading and unloading operations. Therefore, an efficient railway cargo loading and unloading line requires that the electric locomotive can directly arrive at the departure train. Since the fle...

Problems solved by technology

[0004] The purpose of the present invention is to provide a T-shaped overall rotation adjustable wrist arm base, which solves the problem of complex structure, heavy maintenance workload and poor movement track in the cargo loading and unloading line, such as the rigid cantilever structure of the moving catenary or the upward moving linkage mechanism. It is difficult to control accurately, which leads to low working efficiency of the flexible mobile catenary, which affects the operational efficiency of cargo loading and unloading, and meets the needs of efficient work of the mobile catenary and direct arrival of electric locomotives on railway cargo loading and unloading lines.
