Description

Technical Field

[0001] The present invention belongs to the field of hoisting equipment, and particularly relates to a semi-air material transportation device in a tunnel. Background Art

[0002] During tunnel construction, as the excavation face continuously advances, the speed of material transportation is a condition to ensure the construction speed in the tunnel. So far, the material transportation in the tunnel mostly relies on ground transportation tools such as battery cars, tricycles, and flatbed carts. There are often situations such as material blockages in the tunnel, and the ground cannot guarantee smoothness, which has a certain impact on the overall construction progress. There are often situations such as vehicle failures and material blockages in the tunnel, resulting in the ground being unable to guarantee smoothness and the material supply being untimely. Due to the lack of materials, situations such as work stoppages occur, resulting in slow construction progress. To solve this problem, a rail-mounted hoisting device is usually set up in the tunnel to transport the hoisted materials in the tunnel.

[0003] At present, the rail-mounted hoisting devices on the market are divided into two types: single-rail hoisting devices and double-rail hoisting devices. Among them, the single-rail hoisting device occupies a small range of tunnel space and can only move along the track, which is not flexible enough; the double-rail hoisting device can not only transport along the tunnel, but also move horizontally along the vertical tunnel square. However, in the existing double-rail hoisting devices, the two tracks are arranged in parallel, which greatly occupies the limited tunnel space. Summary of the Invention
