Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a trackless transport vehicle that travels within a cylindrical body.

[Conventional technology]

Conventionally, at tunnel excavation sites, transport vehicles for transporting earth and sand have been truck-like vehicles that run manned or unmanned on rails laid in a tunnel.

[Problem that the invention seeks to solve]

However, with such transport vehicles, it takes a considerable amount of time to install and remove the rails, speed must be limited on curves, there is a risk of cargo spillage, and the effective working space of the mine shaft is extremely limited. It had some drawbacks, such as being too narrow.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a self-propelled trackless transport vehicle within a cylindrical body installed at key points, and the transport vehicle has a drive wheel and a plurality of flexible wheels on its lower surface. It consists of a protruding semi-cylindrical truck and a loading platform attached to the truck via a plurality of rollers so that it can swing freely laterally.

[For production]

The cylindrical transport vehicle of the present invention uses the circumferential surface of the cylindrical body as a track, and the dolly can run in a nearly horizontal state with its free wheels. However, the loading platform will naturally swing sideways and become balanced.

〔Example〕

Embodiments of the invention will be described based on the accompanying drawings. As shown in FIG. 1, the present invention is a trackless semi-cylindrical transport vehicle 2 that is self-propelled within a cylindrical body 1 of a required inner diameter, which is installed between a starting point and an ending point, for example, using a mine shaft. As shown in FIG. 2, the transport vehicle 2 includes a trolley 5 equipped with a large drive wheel 3 and a plurality of small caster-type flexible transport wheels 4 on the lower surface;
It consists of a semi-cylindrical loading platform 7 that can be freely oscillated laterally via two pairs of rollers 6 that project above the truck 5.

The cylindrical body 1 has a smooth inner surface, and has a straight line or a slope or curve depending on the installation location.

The trolley 5 of the transport vehicle 2 has a lower surface and a curved surface having a concentric circular cross section (see FIG. 3) with the inner circumferential surface of the cylindrical body 1, and a drive chamber 8 is provided in the front part. A large drive wheel 3 is protruded from the center of the drive chamber 8, and an electric motor 9 and other necessary electrical equipment (not shown) are installed inside the drive chamber 8.

The drive wheel 3 is a rubber wheel and is driven by an electric motor 9 via a belt 10. In addition to the belt 10, a combination of gears and a chino may be used. In addition, the power supply for the electric motor 9 may be from the on-board storage battery, and the cylindrical body 1 may be used as a power source.
It may also be input via a current collector from a trolley wire disposed inside.

The trolley 5 has a pair of swivel wheels 4 on the lower surface of the drive chamber 8 at the front and two pairs of swivel wheels 4 at the rear so as to support the own weight of the transport vehicle and the weight of the cargo almost equally. Two pairs of rollers 6 are attached to a pair of vertical frame plates 11 with their upper halves protruding.

The loading platform 7 consists of a bottom plate 12 whose lower surface has a curved surface with a circular cross section concentric with the upper surface of the truck 5 (see FIG. 4), and front and rear semicircular end plates 13, and is placed on the truck 5. and,
It can be freely swung laterally through rollers 6, and earth and sand A (
(See Figure 4).

Note that the transport vehicle 2 of the present invention can be equipped with various electrical devices such as a travel activation push button and a signal sensing device for stopping, and can be operated automatically. It is also possible to operate by remote control from outside the cylindrical body.

For example, when transporting earth and sand at a tunnel excavation site, this cylindrical body transport vehicle loads earth and sand A onto the loading platform 7 and starts the vehicle.The cart 5 runs in a nearly horizontal state on a straight line, and on a curve, the centrifugal force causes the cart to move. Even if the platform 5 tilts outward, the platform 7 will naturally move horizontally and become balanced.
It has a feature that corrects the slope of the

The cylindrical internal transport vehicle of the present invention can be applied to various transport devices such as transporting earth and sand in a capsule in a factory, in addition to transporting earth and sand in a tunnel as described above.

〔Effect of the invention〕

As described above, since the cylindrical body transport vehicle according to the present invention is trackless, it is possible to omit the labor of installing and removing rails, unlike conventional track transport vehicles, and there is no need to limit speed at curves. There is no spillage of cargo, and the space can be used effectively in, for example, a mine shaft.
