Screw-type synchronous jacking automatic control track plate demolding machine

Abstract

The invention relates to demolding process equipment used in the prefabrication process of high-speed railway ballastless track plates, in particular to a screw-type synchronous jacking automatic control track plate demolding machine. By adopting the demolding machine, the technical problem that the rhythm and strength of workers are hard to synchronize in the mode that the workers conduct demolding on track plates by manually pressing four jacks during the track plate demolding process in the prior art is solved. According to the demolding machine, is adopted; electric energy is used as a power source to be converted into mechanical energy required by the equipment in a motor and speed reducer combined structural form; unique rotating force is transmitted to the four mechanical jacks simultaneously through a transmission shaft and commutator connected structural form; while screw rods rotate, the synchronous jacking process is realized. The problem that four jacking points are not synchronous in the demolding process of track plates in the prior art is solved. The quality of track plates is guaranteed. The demolding machine is flexible, safe and reliable in operation.

Description

technical field [0001] The invention relates to demoulding process equipment in the prefabrication process of ballastless track slabs of high-speed railways, in particular to a screw-type synchronous jacking and automatic control track slab demoulding machine. Background technique [0002] The high-speed railway is an important national infrastructure, the main artery of the national economy and a popular means of transportation. It is the backbone of the comprehensive transportation system and plays an important role in promoting the sound and rapid development of my country's economic society. With the development of high-speed railways, slab ballastless track construction technology has gradually become the most important construction technology in domestic high-speed railway construction, especially the CRTS III track slab construction technology independently developed by my country, which is positioned as the key technology for China's high-speed rail to go abroad. How...

AI Technical Summary

Problems solved by technology

[0004] Using the method of manually pressing four jacks to demould the track slab, it is difficult to synchronize the rhythm and strength of the personnel, and it is easy to have inconsistent heights of the screw rods when the track slab is lifted, causing the concrete of the track slab to fall off, and in severe cases, it will cause rail bearings A large area of ​​the platform falls off or cracks and collapse occur at the lifting point
