The locomotive 6 stops at a position where the second vertical rod 7b in the connecting coupler 7 reaches the vertically upper side of the movable shaft body 8b of the engagement / disengagement mechanism 8 provided on the starting end side of the track 1 (see FIG. 9). At this time, the mooring hole 9c provided on the side surface of the lower end of the transport carriage 2 is also opposed to the pin 9a of the mooring mechanism 9 provided on the starting end side of the track 1 on the same horizontal line.
[0053]
In this state, the pin 9a of the mooring mechanism 9 is pushed forward by the operation of the electric cylinder 9b, and is inserted into and locked in the mooring hole 9c of the transport carriage 2, thereby fixing the transport carriage 2 so as not to move at that position. The movable shaft 8b of the engagement / disengagement mechanism 8 is pushed up by the jack 8d, and the receiving plate 8c is applied to the lower end surface of the second vertical rod 7b of the coupler 7 that connects the transport carriage 2 and the locomotive 6 to each other. The second vertical rod 7b is moved upward integrally with the first vertical rod 7a against the coil spring 16 by being brought into contact with and further pushed up, and the first vertical rod 7a is moved upward from the locking hole 7c on the locomotive 6 side. Let me leave.
[0054]
In this way, the coupling of the coupler 7 between the transport carriage 2 and the locomotive 6 is released, and the locomotive 6 is moved backward to the traverse base 3 side to dispose the first vertical above the transport carriage 2. The locking hole 7c provided on the front end side of the locomotive 6 is separated from the lower side of the rod 7a in the horizontal direction, while the movable shaft body 8b of the engagement / disengagement mechanism 8 is not moved downward, and the first vertical rod 7a is moved downward. The lower end surface is stopped at a position above the locking hole 7c, and is kept waiting for the next connection with the transport carriage 2.
[0055]
On the other hand, the locomotive 6 that has been disconnected from the transport carriage 2 moves backward and returns to the original position on the standby track section 5 from the short track section 4 on the traverse table 3, and is arranged at that position in the same manner as described above. The pin 9a of the mooring mechanism 9 is fixed by being locked to the mooring hole 9c of the locomotive 6 (see FIG. 10).
[0056]
After the locomotive 6 is fixed at a predetermined position on the standby track part 5, the traverse base 3 moves laterally to the lower side of the lifting equipment 30 on one side of the shaft A, and the lifting equipment 30 is moved from the ground into the shaft A. The next transport carriage 2 loaded with the material fed by the elevating frame 31 is received on the short track portion 4 in the same manner as described above, and arranged on the side of the short track portion 4 on the traverse table 3 in the same manner as described above. The pin 9a of the mooring mechanism 9 is inserted and locked into the mooring hole 9c of the transport carriage 2 to fix the transport carriage 2, and after this fixing, it is disposed below the rear end of the short track portion 4. The movable shaft body 8b of the engaging / disengaging mechanism 8 is pushed up by the jack 8d, and the second vertical rod 7b of the coupler 7 provided at the rear end of the transport carriage 2 is moved up as described above to move the first vertical rod The lower end surface of 7a is above the locking hole 7c provided at the front end of the locomotive 6. Keep the state of being stopped at the location.
[0057]
Thereafter, the traverse base 3 is moved laterally to be interposed between the track 1 and the locomotive standby track portion 5 as shown in FIG. The rod 7a is positioned vertically above the locking hole 7c on the front end side of the locomotive 6, and from this state, the movable shaft body 8b is moved downward by the jack 8b to move the first and second vertical rods 7a, 7b to their original positions. The first vertical rod 7a is inserted into and coupled to the locking hole 7c, and the transport carriage 2 is connected to the front end of the locomotive 6 via the connector 7.
[0058]
After connecting the locomotive 6 and the transport carriage 2 in this way, the lower end of the transport carriage 2 is moved by retracting the pin 9a of the mooring mechanism 9 disposed on the side of the short track portion 4 by the electric cylinder 9b. The carriage 9 is released from the mooring hole 9c provided on the side surface of the unit to unfix the carriage 2, and the mooring mechanism 9 disposed on the side of the standby track 5 is also retracted by the electric cylinder 9b. As a result, the locomotive 6 is released from the mooring hole 9c provided on the side surface of the lower end of the locomotive 6 and the locomotive 6 is fixed.
[0059]
Next, as shown in FIG. 12, the locomotive 6 is caused to travel on the short track portion 4 of the traverse table 3 from the standby track portion 5, and the transport cart 2 connected to the locomotive 6 is moved to the start end portion of the track 1. When the locking hole 7c provided on the front end of the carriage 1 reaches the rear end of the transport carriage 2 that has been fed onto the starting end of the track 1, the optical sensor 10 mounted on the locomotive 6 The light is reflected from the reflecting plate 21 and stopped at that position, and the front end locking hole 7c of the transport carriage 2 that has been carried in is provided at the rear end of the transport carriage 2 that has been sent first. It is positioned vertically below the vertical rod 7a.
[0060]
As described above, the first vertical rod 7a pushes up the second vertical rod 7b to a certain height without moving the movable shaft body 8b of the engagement / disengagement mechanism 8 disposed below the first vertical rod 7a. Therefore, the first vertical rod 7a waits in a state where its lower end surface is stopped at a position above the locking hole 7c, so that the front end locking hole of the transport carriage 2 to be fed next is received. 7c can be positioned vertically below the first vertical rod 7a, but after the connection between the transport carriage 2 and the locomotive 6 that have been sent to the starting end of the track 1 is released, the transport carriage The first and second vertical rods 7a and 7c are lowered to their original positions, and when the next transport carriage 2 is fed onto the starting end of the track 1 by the locomotive 6, the engagement / disengagement mechanism 8 is actuated again. The first vertical rod 7a is pushed up to a position above the locking hole 7c. May be.
[0061]
As described above, the front end locking hole of the transport carriage 2 fed next below the first vertical rod 7a provided at the rear end of the transport carriage 2 fed earlier fixed on the starting end of the track 1. After the 7c is positioned, the engagement / disengagement mechanism 8 is operated to move the movable shaft 8b downward, and the first vertical rod 7a received by the upper end support plate 8c of the movable shaft 8b. Is pushed down by the force of the coil spring 17 to be inserted and coupled into the locking hole 7c, thereby connecting the front and rear transport carriages 2 and 2 together.
[0062]
Next, when the transport carriage 2 loaded with the next material is to be continued, the locomotive 6 is moved forward by one transport carriage 2 after the mooring mechanism 9 releases the fixing of the front transport carriage 2. Then, the transport cart 2 on the rear side, that is, the transport cart 2 directly connected to the locomotive 6 is fixed by the mooring mechanism 9, and then the locomotive 6 and the transport cart connected to the locomotive 6. 2 is released in the same manner as described above by operating the engaging / disengaging mechanism 8 below, and only the locomotive 6 is returned to the standby track portion 5 and fixed at that position by the anchoring mechanism 9, and the traverse base 3 Is moved laterally to one side and the carriage 2 loaded with the next material is received from the lifting frame 31 of the lifting equipment 30 and then fixed between the track 1 and the standby track 5 with the mooring mechanism 9 fixed. And is connected by the operation of the engagement / disengagement mechanism 8 as described above. After connecting the locomotive 6 and the transport carriage 2 to each other, the mooring mechanism 9 is released, and the locomotive 6 is moved forward to feed the transport carriage 2 onto the starting end of the track 1. What is necessary is just to repeat the operation | work connected with the conveyance trolley 2 similarly to the above.
[0063]
Thus, after connecting a plurality of transport carts 2 loaded with materials in series, the locomotive 6 connected to the rearmost side is advanced so that these material transport cart trains are connected to the end portion side of the track 1. The material is transported to the construction site in the tunnel, and the material on each transport cart 2 is lowered at the construction site to empty the transport cart.

The locomotive 6 is stopped when the coupler 7 connecting the second transport carriage 2 following the transport carriage 2 reaches above the engagement / disengagement mechanism 8 disposed on the starting end side of the track 1. Let
[0065]
When the locomotive 6 is stopped at this position, the light from the optical sensor 10 mounted on the locomotive 6 is reflected from the reflecting plate 21 disposed at a predetermined position on the track 1 as described above. This is done by detecting In this stopped state, the pin 9a of the mooring mechanism 9 disposed on the side of the starting end of the track 1 faces the mooring hole 9c of the second transport carriage 2.
[0066]
In this state, the mooring mechanism 9 is operated to insert and lock the pin 9c into the mooring hole 9c of the second transport carriage 2 to fix the transport carriage 2 at that position, The coupler 7 that couples the second transport carriage 2 is released by the engagement / disengagement mechanism 8 disposed below the coupler 7. That is, the movable shaft 8b of the engagement / disengagement mechanism 8 is moved upward and the second vertical rod 7b of the coupler 7 is pushed up against the force of the coil spring 17 by the upper end support plate 8c, thereby moving the first vertical rod 7a. It is integrally moved upward and extracted upward from a locking hole 7c provided at the front end of the first transport carriage 2.
[0067]
Then, the horizontal plate piece 19 provided with the locking hole 7c is protruded from the rear end of the second transport carriage 2 provided with the insertion hole 18 of the first vertical rod 7a.

At this time, the first vertical rod 7a inserted through the insertion holes 18 of the upper and lower bifurcated portions 14 ′ and 14 ′ is connected to the engaging / disengaging mechanism 8 below the locomotive 6 before reaching the position of the transport carriage 2. The movable shaft body 8b is pulled upward from the insertion hole 18 by the upward movement, and after the horizontal plate piece 19 is inserted between the upper and lower bifurcated portions 14 'and 14', the movable shaft body 8b is moved downward to The first and second vertical rods 7a and 7b are integrally moved downward in the same manner as described above, and the first vertical rod 7a is inserted and coupled to the locking hole 7c.
[0071]
After the locomotive 6 is connected to the transport carriage 2 through the coupler 7 in this way, the mooring mechanism 9 that fixes the transport carriage 2 is released. Next, when there is a next transport carriage 2 subsequent to the transport carriage 2, the locomotive 6 is moved backward by a distance corresponding to the length of one transport carriage 2, and the transport carriage trains are simultaneously moved to the same distance. The second vertical rod 7b of the coupler 7 provided at the rear end of the transport carriage 2 next to the transport carriage 2 connected to the locomotive 6 is positioned above the engagement / disengagement mechanism 8 vertically. At the same time, the mooring hole 9c is opposed to the pin 9a of the mooring mechanism 9.
