Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling device, and more particularly to a technique for keeping a constant distance between a basic rail and an electric rolling device.

[0002]

2. Description of the Related Art In a rolling device, when a relative position between a basic rail and an electric rolling device is changed, a lock error occurs. Therefore, it is necessary to take technical consideration so that the relative position between the basic rail and the electric switch is not misaligned. As a means therefor, an electric switchboard rail direct coupling device (hereinafter referred to as a direct coupling device) has been proposed and put into practical use. The direct connection device is described in, for example, "Introduction to Electricity for Railway Engineers Series 4 Switching Device" (published by Japan Railway Electrical Engineering Association), pp. 60-62. According to the same description, the direct coupling device is such that when the basic rail moves, the electric turning machine also moves together, and the relative position between the basic rail and the electric turning machine is always kept constant.

[0003]

However, even when the above direct coupling device is used, if a relative position change occurs between the floor plate on which the electric turning machine is mounted and fixed, and the electric turning machine, a change in the basic position occurs. The relative position between the rail and the electric switch changes. The above document does not disclose means for preventing such a change in relative position.

A proposal for preventing a change in the relative position between the basic rail and the electric switch is proposed by Shokai 62-941.
No. 01, Japanese Utility Model Laid-Open No. 63-116501, Japanese Utility Model Laid-Open No. 2-37901, and Japanese Utility Model Laid-Open No. 3-21401. However, these known documents do not disclose a technique of achieving a simple and reliable complete locking with a simple structure.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rolling device for reliably preventing a relative position change between a floorboard and an electric rolling machine and preventing a lock error.

[0006]

In order to solve the above-mentioned problems, the present invention provides a rolling device including a floor plate, an electric turning machine, a first fixing device, and a second fixing device. There, the floor plate is arranged on a sleeper on which a basic rail is placed, and one end of the sleeper viewed in the length direction is in contact with the basic rail, and the electric turning machine is the floor plate. On the sleeper, is fixed on the sleeper together with the floorboard, the first fixing device is provided on one side of the electric turning machine viewed in the length direction of the sleeper, The second fixing device is integrally coupled to the floor plate and receives the side surface of the electric tipping machine on the one side, and the second fixing device has a fixing member and a screw body. Seen in, the other side of the electric switch is provided, the fixing member is integrally connected to the floor plate. The screw body is screwed to the fixing member so that the sleeper can be moved back and forth in the length direction of the sleeper, and the tip of the screw body is brought into contact with the side surface on the other side of the electric turning machine to move the electric turning machine. It is pressed in the direction of the first fixing device.

[0007]

[Function] The floor board is placed on the sleeper on which the basic rail is placed, and one end of the sleeper in the length direction is in contact with the basic rail. In addition, since it is fixed on the sleeper, basically, the relative position between the basic rail and the electric switch is determined by the mounting position of the electric switch on the floor plate. If the mounting position of the electric turning machine with respect to the floor plate is unchanged, the relative position between the basic rail and the electric turning machine is also unchanged. As the means, the present invention includes a first fixing device and a second fixing device.

The first fixing device is provided on one side of the electric turning machine as viewed in the length direction of the sleeper, is integrally connected to the floor plate, and receives the side surface of the one side of the electric turning machine. There is. Therefore, in the electric turning machine, the position variation to one side when viewed in the length direction of the sleeper is prevented by the first fixing device.

The second fixing device is provided on the other side of the electric turning machine when viewed in the length direction of the sleeper. The second fixing device includes a fixing member and a screw body. The fixing member is integrally connected to the floor board, and the screw body is screwed to the fixing member so that it can be moved back and forth in the length direction of the sleeper. The lever is pressed in the direction of the first fixing device. Therefore, the electric switch is
Upon being pressed by the screw body that constitutes the second fixing device,
It is always positioned in a position defined by the first fixing device.

The position of the electric turning machine on the floor plate does not change unless the screw body rotates in the loosening direction. The screw body is hard to rotate in the loosening direction by a natural force unless a rotation force is applied from the outside. It is also easy to adopt a structure that prevents rotation in the loosening direction by means such as disposing a nut between the screw body and the fixing member. Therefore, with a simple structure, it is possible to reliably prevent a relative position change between the floorboard and the electric switch.
