Fireless loopback device of hydraulic transmission locomotive

Abstract

The invention relates to the technical field of a hydraulic transmission locomotive and in particular relates to a fireless loopback device of a hydraulic transmission locomotive. The fireless loopback device of the hydraulic transmission locomotive comprises a frame cross member and bogies, wherein the bogies are connected with universal shafts, a transmission case is connected between the universal shafts, the universal shafts and a transmission shaft are fixedly connected by virtue of bolts, the frame cross member is provided with a mounting frame, the left side of the mounting frame is provided with a flange, the flange is connected with one end of each of the universal shafts by virtue of bolts, the right side of the mounting frame is provided with an open bar, the open bar of the mounting frame is spanned on a camber beam of the bogie, the frame cross member is provided with a steel wire rope and a suspension, and the universal shafts are arranged on the steel wire rope. The fireless loopback device of the hydraulic transmission locomotive is simple in structural design, thus the loopback safety can be guaranteed; a multi-redundancy design is adopted, i.e., the transportation safety can be guaranteed only requiring that three components are not all invalid; and the structural design of the fireless loopback device of the hydraulic transmission locomotive can be used for solving the fireless loopback problem of the hydraulic transmission locomotive with three-axle bogies.

Description

technical field [0001] The invention relates to a fireless return device for a locomotive, in particular to a fireless return device for a hydraulic transmission locomotive. Background technique [0002] Our company supplies Zhenhai GK2C-0002, 0003 hydraulic locomotives. Due to the requirements of the line and related standards, the locomotives must be returned to the locomotive depot without fire. Our company's liquid transmission locomotive is equipped with two three-axle bogies. There is no precedent for domestic three-axle bogie liquid transmission locomotive without fire return. There is no reference material. Moreover, the locomotive passes the Beijing-Shanghai line when there is no fire return. If there is a problem , the loss will not be estimated, so reliability should be given top priority when designing. Due to the tight space below the three-axle bogie locomotive and the particularity of the cardan shaft structure, the design and installation are challenging. ...
