Embodiment Construction

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

[0021] The V-shaped idler frame includes two side idlers 2 and an intermediate idler 3 supported on the idler base 1, and the two side idlers 2 and the intermediate idler 3 form a V-shaped groove;

[0022] Described damping frame comprises two channel steels 5 that are arranged in parallel below the support plate 4, some damping strips 6, and described some damping strips 6 are supported above the support plate 4 by some support strips 7, and the length direction of the damping strips 6 is in line with the belt The conveying direction is in the same direction, and several damping strips 6 form two side damping strips and one middle damping strip, and the groove formed by the two side damping strips and one middle damping strip has the same angle and size as the V-shaped groove; Two connecting plates 8 are respectively fix...

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 of a belt conveyor, in particular to an auxiliary brake friction damping device for a down-carrying belt conveyor. Background technique [0002] At present, there are three types of braking methods for down belt conveyors in my country: electric power, hydraulic pressure and hydraulic power, and hydraulic power is more widely used. The conveyor is braked in two stages by hydraulic brakes and mechanical brakes. Due to the gravity of the material conveyed by the lower belt conveyor, the upper branch conveyor belt will generate a sliding force, especially in the case of a large inclination angle and a long transport distance, the sliding force will greatly exceed the running resistance of the conveyor belt, so that the drive motor will be in the power generation state. run. When stopping and braking, the excess sliding force will all act on the brake, which will increase the temperature of the brake wheel...
