Conveyer belt dynamic mechanical property testing device

Abstract

The invention discloses a conveyer belt dynamic mechanical property testing device. The device comprises a conveyer belt sample supporting part, a load applying part and an electric control part. Theconveyer belt sample supporting part comprises a supporting bottom frame, a conveyer belt sample front clamping part, a carrier roller assembly and a conveyer belt sample rear clamping part. The loadapplying part comprises an oscillating load applying mechanism and a traction load applying mechanism; the oscillating load applying mechanism comprises a vibration exciter, and the traction load applying mechanism comprises a connector and a traction tensioning assembly; and the electric control part comprises a dynamic signal sensor, and the dynamic signal sensor comprises an acceleration sensorand a displacement sensor which are arranged on a carrier roller assembly. The conveyer belt dynamic mechanical property testing device has the advantages that, the actual stress wave propagation working condition of the conveyer belt under pressure can be simulated through the vibration exciter; the actual traction stress condition of the conveyer belt can be simulated through the traction tensioning assembly, and dynamic mechanical property parameters of the conveyer belt are tested through feedback of the acceleration sensor and the displacement sensor.

Description

technical field [0001] The invention relates to a mechanical performance testing device, in particular to a conveyor belt dynamic mechanical performance testing device for measuring dynamic mechanical performance parameters of a conveyor belt under actual working conditions, and belongs to the technical field of belt conveyors. Background technique [0002] Belt conveyor is a kind of machinery that transports materials in a continuous manner through friction drive, mainly including frame, conveyor belt, idler roller, roller, tensioning device, transmission device, etc. Conveyor belt is the main component of traction and carrying materials, it should not only have sufficient strength, but also have corresponding carrying capacity. Conveyor belts are usually composite materials composed of plastics, rubber, steel cords or nylon cords. Because of their viscoelasticity in mechanical properties, conveyor belt materials are called viscoelastic materials. For long-distance conveyo...

Problems solved by technology

Under normal circumstances, the manufacturer of the conveyor belt only provides the static mechanical performance parameters of the conveyor belt. However, the static mechanical performance of the conveyor belt cannot correctly represent the dynamic mechanical performance of the conveyor belt, especially in the harsh working conditions such as coal mines. In the place of use, even if the conveyor belt meets the parameters of static mechanical properties during use, there will be various problems such as cracks and broken belts.
