Embodiment Construction

[0020] The auxiliary brake friction damping device of the downward belt conveyor is composed of a damping frame, a V-shaped roller frame and two spring dampers.

[0021] The V-shaped roller rack includes two side rollers 2 and a middle roller 3 supported on the roller rack base 1, and the two side rollers 2 and the middle roller 3 are surrounded to form a V-shaped groove;

[0022] The damping frame includes two steel channels 5 arranged in parallel below the support plate 4, a number of damping strips 6, the damping strips 6 are supported above the support plate 4 by a number of support strips 7, and the length direction of the damping strips 6 and the belt The conveying direction is the same, and a plurality of damping strips 6 form two side damping strips and a middle damping strip. The two side damping strips and one middle damping strip are surrounded by a groove with the same angle and size as the V-shaped groove; A connecting plate 8 is fixed at the lower two ends of the chan...

Abstract

The invention relates to an auxiliary device of a downward belt conveyor and in particular relates to an auxiliary bake friction damping device of a downward belt conveyor. The auxiliary bake friction damping device of the downward belt conveyor comprises a damping rack, a V-shaped support roller rack and two spring dampers, wherein the V-shaped support roller rack comprises two side support rollers and a middle support roller which are supported on a base of the support roller rack; the two side support rollers and the middle support roller are surrounded to form a V-shaped groove. The auxiliary bake friction damping device of the downward belt conveyor is capable of effectively overcoming excessive downward sliding force in the downward conveying process of the downward belt conveyor, avoiding the operation of a motor in the generation state, avoiding the phenomenon that the belt is faster and faster under the condition of overload, avoiding the galloping accident, assisting the brake and reducing the speed.

Description

Technical field [0001] The invention relates to an auxiliary device for a belt conveyor, in particular to an auxiliary braking friction damping device for a downward belt conveyor. Background technique [0002] At present, there are three braking methods for downward belt conveyors in my country: electric, hydraulic and hydraulic, and hydraulics are more widely used. The conveyor is braked in two stages by a hydraulic brake and a mechanical brake. Due to the gravity of the material conveyed by the lower belt conveyor, the upper branch conveyor belt produces a sliding force, especially when the oblique angle is large and the distance is long, the sliding force will greatly exceed the running resistance of the conveyor belt, so that the drive motor is in a power generation state. Run down. When the brake is stopped, the excess sliding force will all act on the brake, which will increase the temperature of the brake wheel, and even cause brake failure and runaway accidents. Summa...
