Technology of changing railway switch construction and its equipment of changing railway switch

Abstract

The invention discloses a replacing the railway turnout construction technology and turnout change-lay device. Hydraulic machinery device is adopts in key construction procedure of replacing the railway turnout. The device is made up of hydraulic power unit, many sets of turnout roof fall device connected to the hydraulic power unit, a set of turnout vertical drive device, crossbar direction supported two-wheeled vehicle, cross-rail, universal-wheeled device, supporting metal plate. The construction efficiency, safety quality and construction technology are improved. The advantages are simple and easy to maintain; big safety factor and high reliability; light weight and easy to dismounting and transport; easy operated and centralized controlled by one man; the speed is satisfied the demand of blockade construction; good synchronism operating mechanism and stability; good commonality.

Description

technical field [0001] The invention relates to a construction technique for replacing a railway turnout, and also relates to a turnout replacement equipment used in the construction technique for replacing a railway turnout. Background technique [0002] At present, railway construction is entering a period of leapfrog development. In the next few years, the scope of railway speed increase will be further expanded. Existing railway equipment can no longer meet the requirements of railway transportation. As an important part of railway transportation equipment, turnouts have a great impact on the passing speed of trains. It is also gradually developing towards high-speed and heavy-duty applications. A new type of track structure combining reinforced concrete turnout sleepers with movable high-speed turnouts and inter-section seamless lines effectively meets the requirements of high-speed trains for basic structures. In order to continuously adapt to the requirements of high...

Problems solved by technology

[0004] The original manual construction method can no longer adapt to this new type of turnout, and the manual construction method has the following defects: 1) Many people operate the same rack press, and the operating force is not synchronized, which often causes personal injury incidents ; 2), the operation of multiple rack presses is not synchronized, and the phenomenon of stuck teeth and jumping teeth often occurs; 3), limited by the working space, it is impossible to use a crowbar to work in some working environments; 4), the switch of the movable switch The weight distribution density of the center part is high, and it is difficult to jack up with a rack press; 5) Since the rack press has a small lifting stroke at one time, it needs to be repeated many times to complete the lifting stroke of the entire turnout

[0005] The cost of mechanized laying and replacing turnout equipment imported from abroad is very high. From the perspective of equipment investment economy, general construction units do not have such conditions, and the equipment is bulky and takes up a lot of space on the railway line.
