Dynamic durability strength tester for conveying belt joint

Abstract

The invention discloses a dynamic durability strength tester for a conveying belt joint. The dynamic durability strength tester for the conveying belt joint is composed of a bottom frame, experimental rolls, a pressure sensor, a driving cylinder, a traction motor, a main motor, a fixed bracket, a movable bracket, an ejection cylinder, a conveying belt test sample, a vertical linear guide rail, a left bearing, a bracket, a screw rod, a belt, a right bearing and a side guide rail and is characterized in that the bottom frame is provided with the fixed bracket and the vertical linear guide rail, the vertical guide rail is provided with the movable stand, the experimental rolls and the ejection cylinder are mounted between the fixed bracket and the movable bracket, the bracket is fixed on the bottom frame and provided with the driving cylinder, the pressure sensor is connected with the driving cylinder and the leftmost experimental roll, the bracket is further provided with the traction motor, the traction motor is connected with the screw rod, one end of the screw rod is provided with the left bearing while the other end is provided with the right bearing, the main motor is fixed on the bottom frame and connected with the rightmost experimental roll through the belt, the conveying belt test sample winds the experimental rolls, and the side guide rail is mounted at the leftmost end of the bottom frame.

Description

technical field [0001] The invention relates to a conveyor belt strength testing machine, specifically a conveyor belt joint dynamic durability strength testing machine composed of test rollers, ejection cylinders, pressure sensors, etc., belonging to the field of testing equipment. Background technique [0002] Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries where the conveying distance is short and the conveying volume is small. According to the contents of the MT / T318.1-1997 coal industry standard, the impurities The belt tearing caused by the large coal and various impurities in the raw coal, such as iron, wooden sticks, etc., will cause about 70-80% of the tearing, so it is particularly important to ensure the quality of the conveyor belt. The joint dynamic durability strength test of the conveyor belt in advance can avoid some accidents, but there is no such equipment on the market at present. Contents of th...
