Description

[Detailed Description of the Invention] The present invention mainly relates to a guide rail joining structure for joining guide rails of a medium-duty rail transportation system using a joint plate.

In order to reduce traffic pollution such as traffic congestion, accidents, noise, and exhaust gas, transportation systems have been put into practical use in which rubber-tired vehicles, such as medium-sized buses, are operated on dedicated tracks using computers.

FIG. 1 shows a conventional example of a rubber tire type vehicle and its guide rail, in which a vehicle 1 has a steering guide wheel 3 protruding from the side thereof and a side wall 6 of a dedicated track 4 having a groove-shaped cross section. The vehicle is steered while being guided by guide rails 7 provided in the vehicle, and travels along a travel path 5 by running wheels 2. The guide rail 7 is made of H-beam steel consisting of a horizontal plate portion 7a and vertical plate portions 7b and 7c partially formed at both ends of the horizontal plate portion 7a.

By the way, conventionally, when joining adjacent guide rails 7, the joint plate 8 is attached to both vertical plate portions 7b, 7 of the guide rail 7, as shown in FIG.
The horizontal plate part 7a is fitted between the parts c and the horizontal plate part 7a is joined using bolts and nuts inserted through the joint plate 8. At this time, the guide ring raceway surface 7d of the guide rail 7 is If one side of the joint plate 8 is fixed in contact with the vertical plate part 7b on the guide wheel rolling surface 7d side of the guide rail 7 so as not to form a step, the minimum dimension of the guide rail 7 (vertical plate parts 7b, 7c) The joint plate 8 is made according to the minimum tolerance between the dimensions
A gap 9 is formed between the guide rail 7 and the vertical plate portion 7c of the guide rail 7. After the guide rails 7 are joined, as time passes, due to temperature changes or repeated loads from the guide wheels 3, the joint plate 8 and the guide rails 7
The problem is that the joint plate 8 and the guide rail 7 move relative to each other in the gap 9 due to loosening between the guide rails 7, 7, and the guide rails 7, which causes a step difference between the guide wheels rolling surfaces 7d, 7d of the adjacent guide rails 7, 7. However, there is a problem in that maintenance work must be performed frequently at regular intervals.

The present invention was developed in view of the above circumstances, and its purpose is to create a joining structure for guide rails that does not create a step at the joint between adjacent guide rails and that requires almost no maintenance and inspection. It is about providing.

In order to achieve the above object, the present invention has two guide rails each having a vertical plate part formed at both ends of a horizontal plate part, with their joined ends facing each other and their lengths aligned. A joint plate is provided in which side plates are formed at both ends of the bottom plate and a flange protrudes outward from the side plate at the edge of at least one of the side plates opposite to the bottom plate. The above-mentioned method is fitted into the joint portion of the two guide rails, straddling both guide rails, with the outer surfaces of the both side plates facing the inner surfaces of the vertical plate portions of the guide rails, while making contact with the horizontal plate portions of the guide rails. It is attached to both guide rails by bolts passed through the horizontal plate part and the bottom plate and nuts screwed onto the bolts, and a wedge with a retainer is attached between the side plate where the above-mentioned flange of the joint plate is provided and the guide rail. The retainer is inserted in the longitudinal direction of the guide rail into the gap formed between the guide rail and the vertical plate part, and the retainer is engaged with the retainer formed on the side plate provided with the collar part. The configuration is such that the
