Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a point switching mechanism which can be applied to a track branching section of various railways, and more particularly to an excavation site of a steep tunnel, which is excavated by a trolley pulled by a steep locomotive. In order to carry out rocks, earth and sand, or to send empty trucks to the excavation site, or to carry in / out various materials and equipment, lay a track with a branch in the tunnel, By running a plurality of steep locomotives with tow trucks on this track, and carrying in and out work efficiently and smoothly, it is effective to apply to the above-mentioned track branch section in the effective track branch section. It relates to a point switching mechanism.

[0002]

2. Description of the Related Art Generally, at a tunnel excavation site, a locomotive connected with a trolley or the like is run by laying a rail from a tunnel entrance to a face to transport excavated earth and sand and materials and equipment. .

[0003] Further, as the excavation progresses, when the distance from the face to the wellhead becomes longer, a branch track is provided in the middle of the basic track so that the locomotive and the like can be smoothly moved from the wellhead side and the face side to be transported. Improving efficiency.

A conventional orbit branching structure (see FIG. 17) provided at a branch portion between the branch orbit and the basic orbit has a basic orbit 101 and two branch orbits 102 and 103 (one is a basic orbit 103). In between, the crossing unit 104,
Four stock rails 1 connected to the crossing section 104
05 and the tongue rail 106 are provided.
By operating the switching machine 107 for converting the base track 6 from the base track 101 to the desired branch track 102 or 10
The orbit has been switched to 3.

[0005] In a tunnel line provided with each of the above-mentioned tracks, a normal locomotive can travel on the track when the slope is gentle, but slippage occurs when the slope is steep. It becomes difficult to run with this locomotive.

Therefore, the two rails 101a and 101b which normally constitute the basic track 101 laid on a steep slope are used.
A rack rail 108 (see FIGS. 15 and 16) is laid between them, and a steep locomotive 109 is running (a so-called apt-type rail). A steep locomotive 109 running on wheels on the basic track 101 is provided with a pinion gear 110 at a position meshing with the rack rail 108, and the steep locomotive 109 is driven while the pinion gear 110 is engaged with the rack rail 108. ing. Further, in order to prevent the steep locomotive 109 from floating on the inclined surface, the steep locomotive 109 is provided with a pair of guide rollers 1 which are not detached.
11 are also provided.
11 is engaged with a pair of U-shaped guides 112 provided on the rack rail 108 side.

For this reason, the pinion gear 110 and the guide roller 111 provided on the side of the steep locomotive 109 protrude downward from the upper surface of the ordinary rail, and the steep locomotive 109 moves from the basic track 101 to the branch tracks 102 and 103 (see FIG. 17). )
When the vehicle enters, it hits the crossing unit 104 or the stock rail 105 and cannot pass.

[0008]

In order to solve this problem, a drive device and a control device for vertically moving the pinion gear 110 must be provided on the steep locomotive 109 side. Then pinion gear 110
Moves up and down, so the pinion gear 11
There is a concern that the steep locomotive 109 slips off due to the deviation from 0, which is a problem from the viewpoint of safety.

The present invention has been developed in view of the above points, and an object of the present invention is to enable a locomotive for steep slopes to pass through a track branching section without any problem, and to efficiently remove dirt and sand. An object of the present invention is to provide a point switching mechanism in a track branching section that can carry out work for transporting materials and the like.
