Rail turnout unit

Abstract

The invention discloses a rail turnout unit comprising concentrated hydraulic power stations for supplying hydraulic power, longitudinal movement power components for supplying longitudinal movement power, transverse movement power components for supplying transverse movement power and lifting power devices for supplying lifting power, wherein the transverse movement power components, the longitudinal movement power components and the lifting power devices are respectively communicated with oil paths at the power output ends of the concentrated hydraulic power stations by virtue of hydraulic hoses and quick couplers. By virtue of concentrated hydraulic power supply, kinetic correlation is formed among the components, and further, the overall deployment of construction is realized, so that the high reliability of the rail turnout unit is achieved. The lifting power devices are clamped on a steel rail in pairs by virtue of symmetrical clamps, thus the rail turnout unit is high in safety. Construction components are separately arranged, and the equipment for completing the lifting and transverse and longitudinal movement actions of sections of the rail is respectively arranged, so that the components can be installed independently, and the installation efficiency of the components is improved.

Description

technical field [0001] The invention relates to the technical field of railway laying and maintenance equipment, in particular to a railway switch laying unit. Background technique [0002] Railway is a track for trains and other means of transportation. Railway transportation is a land transportation method. A locomotive is used to pull trains on two parallel rails. Therefore, rails have become a necessary factor for the realization of train transportation. Due to the large base of railway laying kilometers in my country and the high frequency of train operation, the railway department has a large amount of rail maintenance projects. In the new rail laying project or the repair and maintenance work of the rails, the erection of new rails or the replacement of old and damaged rails are very complicated. When rails are laid and replaced in units of whole sections, due to their large volume and heavy weight, the work has to be carried out by heavy machinery. [0003] In the ...

AI Technical Summary

Problems solved by technology

There are two problems in using this method to move the turnout longitudinally: first, in addition to being equipped with a 250kg electric winch, a special generator is required, weighing about 400kg, which makes the operating machine heavier; second, the traction of the electric winch The speed is fixed and cannot be adjusted, resulting in the inability to decelerate near the stop point when the electric winch is used for pulling, resulting in difficult positioning during longitudinal movement

[0014] 2. The machine is heavy, and it is inconvenient to get on and off the road. It can only be transported to the site by rail car and flatbed car. It must occupy the line and affect the transportation. The indirect cost is very high.

[0015] 3. The cost is very high, and the purchase cost of the supporting units that can be used is about 6 million yuan

It is very difficult to match it to the grass-roots user units at the level of the public works section
