Description

Technical Field

[0001] The utility model relates to a large-angle arc turning device for a belt conveyor, belonging to the field of belt conveyors. Background Art

[0002] As continuous transportation equipment, belt conveyors are widely used in many bulk material transportation occasions such as docks and mines due to their large transportation capacity and high transportation efficiency. Usually, belt conveyors run in a straight line. When encountering directional changes, overlapping transportation is adopted. Especially when encountering curved transportation lines, multi-section overlapping transportation is adopted, which makes the transportation system complex, with many fault points and inconvenient to use; sometimes, non-continuous transportation such as mine car transportation is simply adopted, which increases transportation costs.

[0003] Although the existing broken line turning belt conveyor has solved the problem of belt conveyor changing direction, it cannot be used in the lane with curved turning. The small angle curved turning belt conveyor is generally used in the occasions within 10°. Although the tubular belt conveyor can realize large angle curved turning operation, its structure is complicated, and the transportation capacity of the belt conveyor with the same bandwidth is greatly reduced. There is an urgent need for a belt conveyor that can realize large angle curved turning and continuous changing direction operation using ordinary tape to meet the application of these special occasions. Summary of the invention

[0004] The purpose of the utility model is to provide a large-angle arc turning device for a belt conveyor, which can well solve the above-mentioned problem.

[0009] The return assembly includes a long roller, a return vertical roller and a return pressure roller. The long roller is installed at a certain angle on the unloaded layer of the base, and the return vertical roller and the return pressure roller are respectively installed on the unloaded layer of the base to limit the deviation of the unloaded belt.

[0010] Furthermore, the load-bearing rollers may be triple rollers, quadruple rollers, quintuple rollers or sextuple rollers, which are determined according to the arc radius of the on-site terrain and the belt offset.

[0011] Furthermore, the vertical roller can be installed only on the inner side of the circumference of the roller frame arranged in an arc (on the same side as the centripetal force direction); the installation direction of the vertical roller is adjustable, and can be perpendicular to the ground or can be vertical to carry the tape.

[0012] Furthermore, among every two adjacent groups of the roller assemblies, only one group of the roller assemblies may be equipped with the pressure roller.

[0013] Furthermore, the roller assembly includes a roller frame, vertical rollers and load-bearing rollers, the vertical rollers are installed on both sides of the roller frame, the load-bearing rollers are U-shaped and installed on the bottom side of the roller frame, and the roller assembly is installed on the base carrying layer; a group of vertical roller assemblies is installed between each two adjacent groups of the roller assemblies, the vertical roller assembly includes a vertical roller frame and vertical rollers, and the vertical rollers are installed on the base carrying layer through the vertical roller frame.

[0014] Furthermore, the height of the base is adjustable, and the height of the base can be adjusted according to the height of the ground on site.

[0015] Furthermore, the position of the roller frame can be adjusted forward and backward.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] The modular structure is easy to install and maintain. It solves the problem of the difference in the distance between the inner and outer arcs of the belt when the belt is transported at a large angle, and overcomes the centripetal force of the belt conveyor when it is turned at a large angle, thereby ensuring that the belt conveyor runs smoothly during the continuous transportation process of large-angle arc turns, and there is no loss of transportation capacity. It can be installed at any angle according to the arc angle of the excavation tunnel, without power, successfully solving the problem of continuous transportation of the belt in large-angle arc turns, and can be reused in different arc angles, saving equipment investment.
