Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a securing device for a guide rail that guides a traveling vehicle.

Conventionally, guide rollers 01, 01 shown in FIG. 1 are attached to a traveling vehicle guided by a guide rail, and by sandwiching the guide rail 02 between the guide rollers 01, 01, the traveling vehicle is guided by the guide rail 02. It is designed to run along the same line.
In addition, the guide rail 02 is secured to the guide rail 02.
is grounded on the road surface 03, and bolts 0 are placed on both sides of the lower part of the guide rail 02 via pressing plates 04, 04.
It is designed to be fixed at 5.05.

However, in the above-mentioned lashing structure, the bolts may loosen due to vibration of the guide rail, etc., and as the bolts loosen, they will move upwards, so the bolts may interfere with the movement of the guide rollers. In the worst case, there was a problem that the bolts and guide rollers would be damaged.

The present invention aims to solve the above-mentioned problems, and the following embodiments will be explained with reference to the drawings.
1 is a traveling vehicle that performs inspection or cleaning work on the inner surface 2 of a tunnel.A mounting plate 4 on which a pair of guide rollers 3, 3 are suspended is fixed to the traveling vehicle 1 in a state projecting to the side, A guide rail 5, which will be described later, is sandwiched between rollers 3, 3, and the traveling vehicle 1 is guided by the guide rail 5 while being kept at a constant distance from the tunnel inner surface 2 at all times.

The guide rails 5 have an I-shaped cross section and are provided at regular intervals along the tunnel inner surface 2, and are further fixed by a plurality of lashing devices 6 installed at appropriate intervals.

Since the plurality of lashing devices 6 have the same structure, one of them will be explained. The lashing device 6 is composed of a support frame 7 and a plurality of hooks 8. The support frame 7 has vertical support parts 9, 9 and a horizontal grounding part 1.
0,10,
A grounding portion 10 is fixed to a road surface 11 with bolts 12, 12 in a state substantially orthogonal to the guide rail 5.

In addition, grooves 13, 13 having the same length as the width of the lower end of the guide rail 5 are cut out in the upper parts of both the support parts 9, 9, and by fitting the lower end of the guide rail 5 into the grooves 13, 13, the guide rail 5 It is designed to restrict movement of the body to the side.

The hooks 8 are rotatably supported by bolts 14 at front, rear, left and right positions on the outside of the support parts 9, 9, and by rotating the hooks 8, the upper surface of both ends of the lower part of the guide rail 5 is rotated. The bolt 14 can be engaged and secured together with the bolt 14.
The hooks 8 can be fixed in the above-mentioned engaged and secured state by means of nuts 15 that are screwed together.

In the embodiment, the support frame is formed into a mold, but it is not necessarily limited to this shape, and any shape that allows the formation of grooves and the attachment of hooks will have the same effect.

In addition, the mounting position of the hook is not limited to the support part, but can also be attached to the ground contact part, and the formation of the groove is not limited to cutting out the support part, but forming a groove separately in the support part. A similar effect can be obtained even if an auxiliary member for forming is attached.

The present invention has the above-mentioned structure, and its operation will now be explained. When fixing the guide rail 5, each hook 8 is rotated to the outer position, that is, the position shown by the solid line, as shown in FIG. In this state, move the guide rail 5 from the solid line position to the dashed line position in the direction of the arrow, and insert the groove 13 in the lower part of the guide rail 5.
Insert into 13.

In this state, rotate the hooks 8 from the solid line position to the dashed-dotted line position, engage and secure both ends of the lower part of the guide rail 5, and tighten the nuts 15 that had been loosened until then to fix the hooks 8... do. This restricts vertical and lateral movement of the guide rail 5 and securely fixes it.

When removing the guide rail 5, it can be removed in the reverse order.

As described above, in the present invention, the lateral movement of the guide rail is regulated by the groove on the support frame side, and the vertical movement is regulated by the hook provided on the support frame. This eliminates the need to use bolts and prevents the movement of the guide rollers.

In addition, since the guide rail can be fixed slightly above the road surface, waste water after cleaning on both sides of the guide rail can flow, making drainage very easy.

[Brief explanation of the drawing]

FIG. 1 is a conventional example, FIG. 2 is an overall view of the present invention, FIG. 3 is an enlarged view, and FIG. 4 is an operating state diagram. 5 is a guide rail, 6 is a lashing device, 7 is a support frame, 8 is a hook, and 13 is a groove.

Claims (1)

[Claims] 1. In a guide rail that guides a traveling vehicle via guide rollers, a support frame that supports the guide rail is fixed to the road surface substantially orthogonally to the guide rail, and an upper part of the support frame is provided to prevent lateral movement of the guide rail. A guide rail securing device for guiding a running vehicle, which is provided with a restricting groove and further rotatably provided on a support frame with a pair of hooks capable of engaging and securing the upper surfaces of both ends of the lower portion of the guide rail.
