Description

Rail Siliding Auxiliary Equipment at Railroad Switch Plate}

The present invention relates to a rail sliding structure of a rail top plate that enables the moving rail to move smoothly on a rail top plate that changes a driving direction of a tracked vehicle. In particular, the roller moves smoothly and moves using a roller. It relates to a rail sliding assistance device of the upper plate of the train to be able to adjust the height of the rail freely.

In general, a tracked vehicle, such as a railroad car, is to travel along a pair of rails only in a predetermined direction. However, when the track vehicle runs only in a predetermined direction, the track vehicle cannot be driven to a desired position, so it is necessary to change the driving direction of the track vehicle. The device for changing the traveling direction of the tracked vehicle as described above is called a train, also called a track conversion device.

A conventional train system is installed in a position where a pair of rails are separated into two pairs of rails as is well known. It consists of a rail, a switching device for moving the moving rail at the same time, and a rail top plate for guiding the movement of the moving rail by manipulating the switching device, and operating the switching device to move the moving rail from side to side. The moving rail is in contact with either one of the first fixed rail or the second fixed rail branched from the first fixed rail and is spaced apart from the other side so that the traveling direction is changed.

On the other hand, in a conventional train top plate system, a fixed rail is fixedly installed on one side of the bottom plate installed on the sleeper, and a sliding surface is formed on the other side of the bottom plate so that the movable rail is movable along the sliding surface. At this time, since the friction force acts greatly between the moving rail and the sliding surface, the sliding surface is periodically applied with waste oil or lubricating oil to reduce the frictional force so that the moving rail moves smoothly along the sliding surface.

If waste oil or lubricating oil is not periodically applied to the sliding surface, waste oil or lubricating oil may be oxidized by rain or snow, so that even if the switching device is operated, the moving rail does not move well, making smooth running of the tracked vehicle difficult. Therefore, waste oil or lubricating oil is periodically applied to the sliding surface. However, when applying the waste oil or lubricating oil to the sliding surface, a lot of manpower is consumed, a safety vehicle may occur as the track vehicle progresses during the applying operation, and the applied waste oil or lubricating oil may cause soil and groundwater to be contaminated. There is a problem that the surroundings become dirty and difficult to clean.

Accordingly, devices that allow the moving rail to move smoothly by using rollers instead of applying waste oil or lubricating oil to sliding surfaces have been proposed.

No. 6,464,177 B1 is a roller for guiding the movement of a moving rail using two rollers having an eccentric shaft and adjusting the height of the roller using an eccentric roller shaft while being separated up and down to support the roller. The frame can move in the axial direction. However, the above-mentioned US patent has the end outer peripheral surface of the roller shaft is formed in a knurled structure to prevent rotation between the roller frames divided up and down, so that the roller shaft can be rotated together with the roller and due to the knurled structure of the roller shaft being rotated There is a problem that the roller frame may be damaged.

In addition, since the roller cover is fixed only by the fixing bolt, the roller cover can be easily released by the impact and vibration acting on the moving rail, and the end of the eccentric roller shaft has a stepless structure, making it difficult to accurately determine the height of the roller. There is this.

In addition, Korean Patent No. 10-0874181 has an eccentric rotation shaft for height adjustment is assembled inside the roller cover, there is an inconvenience to dismantle the roller cover when adjusting the roller height, the rotation eccentric shaft is also provided with only two sides There is a problem that it is difficult to apply to the actually installed moving rail because it is impossible to adjust a variety of height. In addition, there is a problem that the amount of movement in the horizontal direction is limited by the pitch of the teeth.

The present invention has been made in order to solve the above-mentioned conventional problems, and to form an eccentric structure for the rotational support of the roller in the eccentric structure and to form an end of the eccentric shaft in a polygonal shape so that the roller cover and the bottom plate in contact with the eccentric shaft It is an object of the present invention to provide a rail sliding assistance device of a train upper plate that can stably support and accurately adjust the height of a roller by rotating an eccentric shaft.
