Sleeper replacing machine with crossing sleeper and push-pull sleeper integration device

Abstract

The invention discloses a sleeper replacing machine with a crossing sleeper and push-pull sleeper integration device. The sleeper replacing machine comprises a sleeper four-nut synchronous dismantling and installing device, a sleeper lifting device, a crossing sleeper and push-pull sleeper device, a generator, a hydraulic system, a control system box and a track vehicle. The track vehicle is provided with four trundles and two longitudinal beams. The sleeper four-nut synchronous dismantling and installing device, the sleeper lifting device, the crossing sleeper and push-pull sleeper device, the generator, the hydraulic system and the control system box are arranged on the two longitudinal beams of the track vehicle, and the track vehicle is pulled by an engineering vehicle. According to the sleeper replacing machine, a working device is automatically aligned with the working position, synchronous dismantling and installation of four nuts can be achieved, so that pre-tightening force of the four nuts is consistent, the fatigue life of a bolt is improved, and sleeper and steel rail connection reliability is ensured. The sleeper replacing machine can adapt to relevant operation of straight line and curve rail section sleeper replacement, a crossing sleeper and a push-pull sleeper are an integrated device, and the sleeper replacing machine is simple and compact in structure, is controlled automatically and is convenient to operate and high in sleeper replacement working efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a sleeper changing machine with an integrated device of a rotating sleeper and a push-pull sleeper. 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 object of the present invention is to provide a sleeper changing machine with an integrated device for turning sleepers and push-pull sleeper...
