Multi-purpose material conveying vehicle for coal mine tunneling

Abstract

The invention discloses a multi-purpose material conveying vehicle for coal mine tunneling, and relates to a multi-purpose material vehicle. Wheels (3) are arranged at the two ends of an axle (4) respectively. The middle part of an M-shaped vehicle plate is fixedly connected to the middle part of the upper surface of the axle (4). One end of a steel pipe (2) is fixedly arranged on the lower part of one end of the middle plate (6) of the M-shaped vehicle plate, and the other end of the steel pipe (2) forms a handle. The M-shaped vehicle plate is arranged on the axle between the two wheels, so that four or more pieces of U-shaped steel can be conveyed at the same time; and side plates are combined with the middle plate to realize a limiting function, so that the displacement of the U-shaped steel is avoided, and the conveying safety of the U-shaped steel is ensured.

Description

【Technical field】 [0001] The invention relates to a multi-purpose material vehicle, in particular to a multi-purpose material transport vehicle during coal mine excavation. 【Background technique】 [0002] It is known that U-shaped steel is usually used as the support of the protective structure in the coal mine working face. However, the transportation of materials in the excavation face, especially the transportation of U-shaped steel, has always been the key to affecting the construction progress. During the excavation period, the U36 plastic support is adopted. The support adopts a 4-section structure, and the net weight of each support is about 490kg. During the excavation period, 4 supports shall be erected in each shift, and 20 U-shaped steels (including the center column) shall be used for each shift. The use of the existing flatbed trolleys to manually transport materials takes a long time, and the labor intensity is high. Once the U-shaped steel is displaced due to ...

[0002] It is known that U-shaped steel is usually used as the support of the protective structure in the coal mine working face. However, the transportation of materials in the excavation working face, especially the transportation of U-shaped steel, has always been the key to the construction progress. During the excavation period, U36 plastic support was used for support. The support adopts a 4-section structure, and the net weight of each support is about 490kg. It takes a long time to use the existing flat trolley to manually transport materials, and the labor intensity is high. Once the U-shaped steel is displaced by the terrain during the handling and transportation process, it will often cause scratches or bruises on the workers, and the underground excavation face is affected by geological conditions. Affect the narrow roadway, which is not conducive to manual material transportation
