Description

[Detailed description of the invention] The present invention is designed to operate a mining vehicle such as a slag truck for transporting sludge within a tunnel in order to carry out the earth and sand from the face of the tunnel to the outside. It is related to the device.

Conventionally, in the maneuvering of such mine cars, a maneuvering area A is provided in the tunnel as shown in Fig. 1, and a main track 1 is connected to this area.
and extend one end of it into the shielded excavation area B via the material lock 2, and extend it into the shielded excavation area A.
A bypass line 5 is provided at both ends of the main line 1 connected to the main line 1 via points 3 and 4, and several mining cars and a locomotive (battery car) connected thereto are provided.
For example, using three sets of transport vehicles consisting of 9 and 8, transport vehicle A, which has loaded and transported earth and sand from excavation area B, is routed to main track 1.
The ore car was parked at the earth and sand transport section C between points 3 and 4, and the work was carried out to transport the earth and sand outside, and at the same time, the mine car was switched to point 3, which is closer to the excavation area B, and was kept on standby on the bypass line 5 until then. The entrance of the transport vehicle is advanced into the excavation area B to carry out the loading work of earth and sand, and the transport vehicle of the already empty ore car is advanced along the main track 1 from point 4 in advance of the transport vehicle A. It is put into the lead-in line 1' connected to the downstream side, then reversed, switched point 4, put it into the bypass line 5, and waited there.Such operations are repeated one after another to continuously remove soil and sand. We are trying to carry out the removal.

However, in the above-mentioned device, each of the three sets of ore car couplings used for distantly related continuous operations must be moved by a locomotive, and a total of three locomotives are required. Locomotives are expensive, and champion locomotives require their own operators, and if more locomotives are connected, the total length of the transport vehicle will naturally increase, so the point 4 on main line 1 was exceeded. The length of the lead-in track 1' must be increased, and the vehicle handling area A in the tunnel must be increased accordingly.
There are disadvantages such as the need to widen the area.

The present invention is intended to eliminate the above-mentioned drawbacks, and a preferred embodiment of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIG. 2, the area including the downstream portion of the main track 1 beyond the earth and sand discharge portion C and the lead-in track 1' is sloped upward toward the lead-in track 1'.

Further, a mine car pulling body 6 is provided so as to move along the side of the main track 1 including the earth and sand carrying section C and the lead-in track 1', and a wire 7 is fixed to this pulling car 6. A winch drum 8 for winding up the lever wire 7 is provided.

In the illustrated example, both ends of a long wire 7 are fixed to the front and rear ends of the towing vehicle 6, and a portion of the wire 7 is wound around the winch drum 8 via pulleys 9 and 10.

11 is a winch motor. The traction body 6 is provided with an engaging portion that protrudes toward the main track 1 and engages the ore car releasably from the side thereof, and the ore car of the engaging portion is provided on the side of the lead-in track 1'. A release mechanism, such as a post 22 to be described later, is provided for releasing the engagement with the mine, and a stopping mechanism 12 is further provided for stopping the mine car in relation to the standby position of the bypass line 5.

More specifically, as shown in FIG. 3, a track 14 with an engineered cross section is laid using H-shaped steel so as to extend along the rail 13 of the main track 1, and two spaces 14' of this track 14 are constructed.
A pair of running wheels 15 are disposed at the front and rear so as to be located inside the track 14, which partitions the space 14'.
A pair of anti-swing wheels 16 are disposed at the front and rear of the center wall of the tow body 6 so as to face each other from both ends thereof.
As shown in FIG. 4, an engaging member 17 is pivotally attached to the upper part of this pulling body 6 so as to rotate in a horizontal plane, and is attached outwardly to the lower side of the ore car 18 on the rail 13. The engaging member 17 is restrained by a spring 20 in an outwardly protruding state so that the distal end engaging portion 17' of the engaging member 17 engages with the protruding portion 19 provided to protrude.

Further, a cam member 21 having cam surfaces at the front and rear is fixed to the lower part of the distal end engaging portion 17' of the engaging member 17, and a post 22 is provided vertically as the release mechanism, and the head of the post 22 is fixed to the lower part of the distal end engaging portion 17'. The cam member 21 is positioned on the movement path of the outer side surface portion of the cam member 21.

However, the height of this post 22 is set so that it is not located on the moving path of the protrusion 19 of the ore car.

As the stopping mechanism 12, a braking mechanism, a wheel stopping mechanism, etc., which slides against the side surface of the mine car, can be used.

Further, when the track 14 is used, the wire 7 is connected to the track 1.
It is preferable to run within the space 14' within 4.

The present invention also uses at least three ore car connections and at least two locomotives.

In the present invention, first, the engaging portion 17' of the engaging member 17 of the traction body 6 is engaged with the protrusion 19 of the ore car 18 of the ore car coupled body without a locomotive located in the earth and sand carrying section C, and the winch The drum 8 is driven to wind up the wire 7 and pull the connected body into the lead-in line 1'.

When the entire coupling body enters the lead-in line 1', the release mechanism is activated.

For example, the head of the post 22 comes into contact with the front cam surface of the cam member 21 provided on the engaging member 17, whereby the retaining member 17 is pushed against the spring 20 and rotates in the direction of the arrow. As a result, the engaging portion 17' becomes disengaged from the protrusion 19 of the mine car 18.

When this connection is broken, the mine car connection begins to move backwards because the lead-in track 1' is inclined.

At this time, point 4 is switched to put the connected body into bypass line 5, and stop mechanism 12 stops it at the standby position.

Further, the disengaged pulling body 6 reverses the winch drum 8 and causes it to move backward, returning to the initial position.

In this reverse movement, when passing through the post 22, the engaging member 17 is retracted or returned by the cam member 21.

In order to make it easier for the post 22 to pass when the towing body moves backward, for example, as shown in FIG.
It is possible to provide a post 22 which is restrained by a spring so that it does not deform due to a force from ) but whose head easily tilts as shown by the chain line when a force from the opposite direction (arrow ■) is applied.

In the present invention, as described above, the empty ore car assembly without a locomotive is moved from the earth and sand discharge section C to the standby position on the bypass track 5, and then the locomotive loaded and transported with earth and sand from the excavation area B. When the ore car assembly with the ore car assembly reaches the earth and sand transport section C, the locomotive is separated from the ore car assembly, and the earth and sand transport work is carried out on the ore car assembly, and the locomotive is allowed to proceed independently and the locomotive is moved to the siding line. 1', switch the point 4 to go backwards, and connect it to the ore car connector in the room that was waiting on the bypass line 5.

On the other hand, the ore car continuous body in the earth and sand transport section C, which has become empty after the earth and sand transport work has been completed, is pulled by the towing body 6 and the lead-in track 1
', and subsequently the subsequent ore car combinations are guided to the excavation area B.
The empty ore car assembly, in which the locomotive was connected at the bypass track 5, was brought into the excavation area B together with the locomotive, and then the ore car assembly was pulled to the lead-in track 1'. The body is made to move from the lead-in line 1' to the bypass line 5, and is stopped at a standby position.

Repeat this operation sequentially. Thus, according to the present invention, it is possible to eliminate the need for one locomotive and its operator, and in addition, the equipment such as the traction body 6, track 14, wire 7, winch drum 8, winch motor 11, etc. The cost of the power required for driving is very low compared to the cost of one locomotive and the power required for driving it, and in addition, the position of the traction body 6 can be detected by a limit switch etc. to control the device of the present invention, e.g. It becomes easy to automatically stop the normal rotation of the winch drum 8, start and stop the reverse rotation of the winch drum 8, and switch points.

Furthermore, since the traction body 6 engages with the side surface of the mine car to pull it, the length of the lead-in track 1' may be large enough to accommodate the entire mine car connection, and The vehicle maneuvering area A can be narrowed by a length corresponding to the length of , which is an extremely large advantage when the length and width of the vehicle maneuvering area are limited.

As described in detail above, the mine car handling system of the present invention has an extremely simple configuration, which makes it possible to reduce the number of locomotives, and also allows the earth and sand transport work to be carried out continuously in the same manner as before. It can significantly reduce equipment costs and power costs, save on personnel, is safe, and can be easily automated, providing extremely large benefits.
