Problems solved by technology

[0002] During the long-term use of railway sleepers, due to natural settlement and vibration, the railway track bed partially subsides and needs to be maintained. Individual sleepers are damaged and need to be replaced in time. During the process of track bed maintenance or sleeper replacement, manual work is used , time-consuming and labor-intensive, low work efficiency

Abstract

The invention discloses a sleeper replacement device based on mechanical-electrical-hydraulic integration. The device is composed of a four-nut synchronous assembling and disassembling device for a sleeper, a rail-lifting device, a sleeper rotating, pushing and pulling device, an electric generator, a hydraulic system, a control system box and a rail car. The rail car has four trundles and two longitudinal beams. The four-nut synchronous assembling and disassembling device for the sleeper, the rail-lifting device, the sleeper rotating, pushing and pulling device, the electric generator, the hydraulic system and the control system box are arranged on the two longitudinal beams of the rail car. The rail car is pulled by an engineering vehicle. The sleeper replacement device based on mechanical-electrical-hydraulic integration has following beneficial effects: the device is capable of automatically aligning a working device to the working position and capable of synchronously assembling and disassembling four nuts such that pre-stress force of the four nuts is the same and fatigue life of bolts is prolonged; reliability between the sleeper and steel rails is ensured; sleeper changing operation can be suitable for liner and curved rail segments; and the sleeper rotating, pushing and pulling device is an integrated device; and the device is simple and compact in structure, automatic in control, convenient in operation and high in sleeper changing efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an electromechanical-hydraulic integrated sleeper replacement device. Background technique [0002] During the long-term use of railway sleepers, due to natural settlement and vibration, the railway track bed partially settles and needs to be maintained. Individual sleepers are damaged and need to be replaced in time. In the process of track bed maintenance or sleeper replacement, manual work is used , time-consuming and labor-intensive, low work efficiency. The work cannot be completed within the effective train passage gap (commonly known as: skylight). Only by using small and efficient automatic machinery can the train passage gap be used for unsealed road operations. Contents of the invention [0003] The purpose of the present invention is to provide an electromechanical-hydraulic integrated sleeper replacement device. [0004] The present invention is composed of four nu...
