Problems solved by technology

Its disadvantages: because the roller-sliding bed is a special widened backing plate, the manufacturing process is complicated and the cost is high, and the cushion under the board also needs a special design, which greatly increases the cost of the turnout, so the roller-sliding bed The structure is not conducive to popularization and application in lower price turnouts
If it is used to optimize and improve the pulling power of the existing turnouts on the line, the slide bed needs to be replaced, which is not only expensive, but also difficult to construct.

Embodiment 1

[0015] Embodiment 1: with reference to attached Figure 1-7 . A roller installation device for a turnout switch, which is composed of a roller installation base plate 1, an iron stopper 2, an outer pressure plate 3, an inner pressure plate 4, bolts 5, and nuts 7. When installing, the inner pressure plate 4 is first fixed on one side of a rail leg The contact surface of the outer pressure plate 3 on the other side of the rail leg and the iron stopper 2 is a slope, and the position of the outer pressure plate 3 is adjusted according to the width of the bottom of the rail. The outer pressure plate 3 and the roller mounting base plate 1 pass through bolts 5, washers 6, and spring washers 9 Connect with nut 7, double roller device or single roller device can be installed on the roller installation base plate 1. During the double roller device, the rollers are installed on the roller device base plate 1 one after the other. In order to prevent the nut 7 from failing due to vibrati...

Embodiment 2

[0017] Embodiment 2: On the basis of Embodiment 1, a working method for the roller installation device of the point switch, the roller installation device is installed on the basic rail between the two switch sleepers within the range of the point switch, and the rollers are installed on the installation device , when the point rail is pulled, the sliding friction is changed into rolling friction through the roller, which reduces the force of the point rail.

Abstract

The invention relates to a roller mounting device applicable to being mounted between switch ties of a turnout switch, and an operating method of the roller mounting device. Through the roller mounting device, a roller is mounted in the range of the turnout switch without demounting a turnout; the problem that the existing switch rail experiences large pull resistance and shifts with inadequacy can be solved effectively. The roller mounting device comprises a roller mounting bottom plate, an iron stop, an outer pressure plate, an inner pressure plate, bolts, and nuts; the inner pressure plate is fixed to one side of a steel rail arm; the face, in contact with the iron stop, of the outer pressure plate on the other side is a slant; the position of the outer pressure plate is adjusted according to the width of the bottom of a steel rail; the outer pressure plate is connected with the bottom plate through the bolts and nuts; both a double-roller device a single-roller device can be mounted on the bottom plate. The roller mounting device has the advantages that after the roller mounting device is used with rollers, integral levelness of the turnout can be increased; the roller mounting device can be conveniently applied to existing railway turnouts, and pull friction of the switch rail is decreased.

Description

technical field [0001] The invention relates to a roller installation device which can be installed between two sleepers of a turnout switch. The roller can be installed in the range of the switch switch without disassembling the switch, which can effectively solve the problem of the existing turnout point on the line. The problem of large rail pulling resistance and insufficient displacement, and at the same time reduce the daily maintenance workload of the turnout maintenance department, and improve the service life of the switch machine. The track switch roller installation device and working method belong to the point switch roller installation device manufacturing field. Background technique [0002] CN201292486Y, name " turnout roller sliding bed board ", this sliding bed board comprises: roller seat, has rectangular hollow, and rectangular hollow both sides is provided with groove; In the groove, the roller is placed in a rectangular hollow; the gasket is supported b...
