Description

Technical Field

[0001] The utility model relates to a continuous belt conveyor used in a tunnel, in particular to a support extension installation structure of a continuous belt conveyor in a tunnel. Background Art

[0002] In the construction of long and large tunnels, the material transportation distance is getting longer and longer, and the requirements for conveying capacity are getting higher and higher. At present, continuous belt conveyors have been widely used in tunnel construction. Most of the belt brackets use triangular steel supports, and a few use double chain suspension. Practice has proved that the triangular steel support has high stability and can effectively ensure the smooth operation of the continuous belt conveyor. However, the triangular steel support is large in size and has low adjustability, which results in high installation intensity for personnel and great difficulty in subsequent adjustment of the continuous belt; the double chain suspension is easy to install and convenient for the operation and adjustment of the continuous belt, but due to the high chain activity and low rigidity, the continuous belt conveyor frequently encounters problems such as the belt bracket ups and downs, left and right bending, and belt flipping during operation. Utility Model Content

[0003] The utility model aims to provide a continuous belt machine support extension installation structure in a tunnel which has good stability and can ensure the continuous belt is adjustable.

[0004] The purpose of the utility model is achieved through such a technical solution, a continuous belt conveyor support extension installation structure in a tunnel, the structure includes a support, a conveyor belt A and a conveyor belt B are respectively arranged on the upper and lower layers of the support, a chain is arranged on one side of the support, and a bar steel support connected to the support is arranged on the other side of the support; the chain and the bar steel support are respectively connected to the tunnel top and the tunnel wall.

[0005] Wherein, the support includes two support beams arranged in parallel, a roller mechanism is arranged between the two support beams, a support beam is arranged horizontally on the lower end surfaces of the two support beams, a U-shaped frame is arranged on the lower end surface of the support beam, and a roller A is arranged horizontally on the U-shaped frame; the chain and the bar steel support are respectively connected to the two ends of the support beam.

[0006] In the utility model, the roller mechanism comprises a connecting frame, on which a roller B is arranged; the conveyor belt A and the conveyor belt B are arranged on the roller B and the roller A respectively.

[0007] Further description: the bar steel support is arranged horizontally, a plurality of bolt holes are arranged on the support beam, and the bar steel support is connected to one end of the support beam by bolts.

[0008] Due to the adoption of the above technical scheme, the utility model has the advantages of simple structure, reliable use and low cost. The structure adopts chain suspension and strip steel support, which is easy to install and highly adjustable. At the same time, the strip steel support is rigidly connected to the tunnel wall, which ensures the operating stability of the continuous belt conveyor and reduces the operating failure rate of the continuous belt conveyor.
