DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railless material transporting apparatus for driving all wheels, loading and transporting material.

[0002]

2. Description of the Related Art In general cargo handling and transport operations, transport by a forklift, transport by a mobile crane, and transport by a transport trolley are widely performed.

[0003] In transporting materials in shield tunnels, rail-type battery locomotives are used.
Railless conveyors have also been proposed.

[0004]

However, the above technique is inconvenient in general transport of a forklift for transporting long objects, and in the case of a transport carriage, the transport range is limited. As a result, in transporting materials in shield tunnels, the rail type has a large loss time and a long cycle time. This was an obstacle to material transport during high-speed construction and steep tunnel construction.

In the case of transporting a piston through a small-diameter tunnel, there is a problem that a transfer device and a place are required for transshipment.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a rail-less material transfer apparatus which has a small loss time and can pick up, transfer and unload goods at any position without a transfer apparatus. And

[0007]

According to the present invention, there is provided a railless material transporting apparatus for driving all wheels to load and transport a material, comprising a pair of front and rear parts of the railless material transporting vehicle. A load receiving base is provided, and a roller having an axis in a direction perpendicular to the traveling direction is provided between the load receiving bases, the roller is supported so as to be able to move up and down, and a connection for connecting a tire driving device and a roller driving device. Means are provided.

Further, according to the present invention, the roller is pivotally attached to a frame by a rod, and the rod is supported by a hydraulic cylinder.

According to the present invention, the connecting means comprises a chain and a sprocket wheel.

According to the present invention, the connecting means is constituted by a gear.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is constructed as described above. Materials to be conveyed are loaded on a receiving base so as to straddle a plurality of carts, and a plurality of carts are simultaneously driven at the same speed for conveyance. For example, in the case of intermediate delivery, raise the rollers of the truck in the traveling direction, move the truck by driving the rollers and tires to the opposite side to the traveling direction, and move the empty truck to the space formed outside. insert. The roller of the empty truck is raised, the load is received by the roller, and the roller of the intermediate truck is lowered.

The intermediate carriage is moved to the side of the carriage opposite to the traveling direction, the rollers are lifted to receive the load, and the carriage with no load is moved, and then the rollers are rotated to the end of the load. If it moves and the roller is lowered, one truck is replaced and the delivery of the load is completed.

Further, in the case of the segment transport of the shield tunnel, the transport can be carried on a pair of load receiving bases, and the transport material can be used irrespective of the tunnel where the passes can be made.

Therefore, even in a small-diameter shield that cannot pass each other, an efficient transfer operation can be performed by the piston transport without the transfer device, and it is not necessary to prepare a material transfer vehicle for each application.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a railless material transport vehicle 1 of the present invention. Wheels 2 and 2 having tires provided in front and rear are rotatably provided on a frame 15 (see FIG. 2). Sprocket wheel 4a of motor 3 mounted on frame and sprocket wheel 2a mounted on wheel
Are connected by a first chain 5 and a second chain 6, respectively.

Referring also to FIG. 2, one end of a rod 9 supporting the roller 14 is pivotally mounted concentrically with one of the front and rear axes, and the roller 14 is rotatably mounted on the other end of the rod 9. The rod 8 of the hydraulic cylinder 7 is provided
The hydraulic cylinder 7 is pivotally connected to the frame 15 by pins 17.

The sprocket wheel 11 provided on the roller shaft is connected to a roller driving device (not shown) and the chain 1.
2, the roller driving device is connected to a tire driving device (not shown) by a chain, and the peripheral speed of the tire 2 and the peripheral speed of the roller 14 are set to be the same.

Reference numeral 13 indicates a receiving base, and reference numeral 14
a shows a state in which the roller 14 is raised to a position higher than the load receiving base 13 by the hydraulic cylinder 7.

Hereinafter, with reference to FIGS. 3 to 11, the operation of transporting, transferring, and exchanging the bogies using the material transport vehicle 1 of the present invention will be described.

In the case of general transport, as shown in FIG. 3, a load 20 is supported and transported by a load receiving base 13 of a plurality of trucks (two in the illustrated example) 1a and 1b.

In the case of delivery, the first and second carts 1a and 1b are stopped near the third cart 1c as shown in FIG. 4 (first step), and the second cart is stopped as shown in FIG. The roller of the truck 1b is raised to the raised position 14a (second step), and the roller is rotated while the roller is raised as shown in FIG. 6, so that the second truck 1b is moved inward, and the third truck is moved. Load 20 of 1c
(Third step). Next, as shown in FIG. 7, the roller of the second truck 1b is lowered, and the roller of the third truck 1c is raised to the ascending position 14a (fourth step).
Is moved to the position next to the first truck 1a (fifth step). As shown in FIG. 9, the roller 14 of the second truck 1b is raised to the rising position 14a, the roller of the third truck 1c is lowered (sixth step), and the first truck 1a is taken out from under the load 20, If the second carriage 1b is moved to the end of the load (7th
Process, FIG. 10), as shown in FIG. 11, the load 20 can be transported by the second truck 1b and the third truck 1c, and the first truck 1a
Can be left off.

Therefore, the transfer of the load and the exchange of the bogie can be performed without the transfer device, and the piston can be transported anywhere in the narrow shield tunnel.

FIG. 12 shows a case in which the segment 20 is conveyed. The segment 20 can be received by the front and rear load receiving bases 13, and can be stably conveyed. In the case of piston transportation that requires transfer on the way, segments are placed on a long pallet and transported by two transport vehicles.

FIG. 13 shows a mode of passing conveyance between the conveyance vehicles 1d and 1f in the shield tunnel 21.

Therefore, a single type of transport vehicle can handle a wide range of transport, and efficient transport can be performed at low equipment cost.

[0027]

The present invention is configured as described above and has the following excellent effects. (1) By using a plurality of trolleys, materials, particularly long ones, can be stably transported. (2) Using a plurality of carts, transport and delivery can be performed without a transfer device. (3) Therefore, even in a small-diameter shield tunnel, materials can be transferred at an arbitrary place without a transfer device, and the piston of the material can be transported. (4) Therefore, materials can be efficiently transported with simple equipment, the cycle time is short, and the cost is low.
