CN103711049A - Track shifter - Google Patents

Abstract

The invention relates to a track shifter which comprises a base board, wherein two opposite supporting boards are fixed on the base board, an idler wheel is mounted between the supporting board through a rotary shaft, and a bearing is mounted in the idler wheel. According to the track shifter, the situation that a steel rail needs to be lifted manually during rail movement in the prior art is changed, working time and labor are saved, maintenance tasks can be accomplished within the railway blocking period, efficiency is improved greatly, and the safety performance of operation is improved.

Description

A kind of railroad slewer

Technical field

The present invention relates to a kind of railway transportation maintenance auxiliary equipment, particularly a kind of railroad slewer.

Background technology

At Railway Transport Industry, carry out rail while switching tracks operation, often need the mobile long rail linking into an integrated entity with the rail of every 25 meters or 12.5 meters, in the past pure use manual work, because weight is excessive, manually can not lift, must resolve into single movement, and at least want 20 people with stout carrying pole, to operate simultaneously, and disposable displacement is short, physical demands is large, and safety factor is low, and the activity duration is long, job schedule is slow, completes difficulty larger in blocking time.

Summary of the invention

Technical problem to be solved by this invention is, a kind of Simple tool for mobile rail is provided, manpower and physical demands when alleviating rail and moving, and can improve the safety of operation, improve the operating efficiency that rail is safeguarded.

The present invention takes following technical scheme, and a kind of railroad slewer, comprises base plate, and on base plate, is fixed with two relative gripper shoes, between described gripper shoe, by rotating shaft, roller is installed, and bearing is housed in roller.

The invention has the advantages that, changed the situation that in the past adopted people to lift rail when rail moves, saved activity duration and manpower, guaranteed to complete maintenance task in railway blocking time, greatly improved efficiency, improved the security performance of operation.

Accompanying drawing explanation

Fig. 1 is the partial cutaway schematic of structure of the present invention.

Fig. 2 is that the present invention uses view.

In figure: 1. roller, 2. bearing, 3. gripper shoe, 4. rotating shaft, 5. base plate.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described, referring to Fig. 1, a kind of railroad slewer, comprise base plate 5, and on base plate 5, be fixed with two relative gripper shoes 3, between described gripper shoe 3, by rotating shaft 4, roller 1 be installed, bearing 2 is equipped with at the two ends of roller 1 endoporus, rotating shaft 4, through bearing 2 and gripper shoe 3, is fixed between gripper shoe 3 roller 1.

As Fig. 2, adopt railroad slewer when switching tracks operation, first with track jack, rail is risen highly, place a railroad slewer every one section, make to be placed on the wheel face of roller 1 at the bottom of rail, by rolling, rail is transported to desired location.The present invention can be to connecting into the disposable movement of the long rail of 70-80 rice, and result of use is good, and the security performance in work progress improves greatly, has saved extensive work time and labour intensity, has guaranteed construction speed.

Claims (1)

1. a railroad slewer, comprises base plate, and on base plate, is fixed with two relative gripper shoes, it is characterized in that, between described gripper shoe, by rotating shaft, roller is installed, and bearing is housed in roller.
