A method of quickly moving a hydraulic changing frame using a carrier changing frame support

Abstract

The invention discloses a carrying reloading rack support and a method for quickly moving carrying reloading rack by use of a support. The carrying reloading rack support is mounted on the body of an auxiliary engine flatcar of a track laying unit; after the oil cylinder of a hydraulic reloading rack is lifted to the highest position, the auxiliary engine flat car is driven in so that the carrying reloading rack support is aligned to the hydraulic reloading rack; the oil cylinder of the hydraulic reloading rack is lowered down, a load hanging carrying pole falls onto the carrying reloading rack support, the oil cylinder is continuously withdrawn so that the bottom of the hydraulic reloading rack can be separated from a subgrade, the hydraulic reloading rack stretches across the carrying reloading rack support, and then a supporting rod assembly is opened to fix the hydraulic reloading rack; the auxiliary engine flatcar carries the hydraulic reloading rack to an appropriate position, the supporting rod assembly is withdrawn so that the oil cylinder moves up, the hydraulic reloading rack stands on the subgrade, and the auxiliary engine flatcar is driven out. The carrying reloading rack is arranged on the auxiliary engine of the track laying unit; the hydraulic reloading rack can be rapidly transferred without other devices; the production cost is saved while the track laying operation efficiency is improved.

Description

technical field [0001] The invention relates to a method for quickly moving a hydraulic changing rack by using a carrying rack support. Background technique [0002] In recent years, more and more countries have paid attention to railway as a "green transportation" mode with low energy consumption and large capacity. China's railway construction and technical strength coincide with the railway construction needs of many countries. With the active promotion at the national level, Chinese railway enterprises and equipment are gradually entering the world railway stage. China's railway construction technology is at the forefront of the world and has been recognized by more and more countries. As the pace of domestic railway construction slows down, the paving products are becoming more and more severe in the domestic market. Going abroad is the need for market expansion and adapting to the world. The need for railway construction is the embodiment of the core competitiveness o...

Problems solved by technology

[0003] At present, the track-laying unit used by our unit lays 8 kilometers of track per day, and the running speed of the auxiliary machine is 20Km / h (no load) and 10Km / h (heavy load). If it is too long, it will seriously affect the efficiency of track laying. According to calculations, when the distance between the main engine and the changing frame is controlled within 4 kilometers, the track laying efficiency will be the highest, and it is imperative to move the changing frame frequently
