Machine automatic rapid sleeper-changing device

Abstract

The invention discloses a machine automatic rapid sleeper-changing device. The device is composed of a four-nut synchronous assembling / disassembling device, a first track hoisting device, a track-transferring and sleeper pulling-pushing device, a sleeper overhead-hoisting device, a power generator, a hydraulic system and control system box and a track car, wherein multiple truckles and two carlings are arranged on the track car; the four-nut synchronous assembling / disassembling device, the first track hoisting device, the track-transferring and sleeper pulling-pushing device, the sleeper overhead-hoisting device, the power generator and the hydraulic system and control system box are arranged on the two carlings of the track car; and the track car is towed by an engineering truck. The device disclosed by the invention can rapidly align a working device with a working position; four nuts can be synchronously assembled / disassembled, so that the pre-tightening forces of the four nuts are consistent, the fatigue life of a bolt is prolonged, and the connection reliability of the sleeper and a steel rail is guaranteed; the sleeper can be rapidly overhead-hoisted and placed to work; the device is adapted to the sleeper-changing work of linear and curve track sections; the track-transferring and sleeper pulling-pushing device is an integrated device; the device is simple and compact in structure, realizes automatic control, and is convenient for operation, and sleeper-changing working efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a machine-automatic fast pillow changing device. Background technique [0002] During the long-term use of railway sleepers, due to natural settlement and vibration, some railway sleepers sink and need to be maintained. Individual sleepers are damaged and need to be replaced in time. Time-consuming and labor-intensive, the work efficiency is low, and the work cannot be completed in the effective train passage gap (commonly known as: skylight). Contents of the invention [0003] The purpose of the present invention is to provide a machine-automatic fast pillow changing device. [0004] The present invention is composed of a four-nut synchronous assembly and disassembly device, a first rail lifting device, a rail transition and push-pull sleeper device, a sleeper lifting device, a generator, a hydraulic system, a control system box and a rail car. The rail car is equipped with m...
