Steel cable strength testing device for coal equipment

Abstract

The invention provides a steel cable strength testing device for coal equipment, and relates to the technical field of steel cable strength detection, so as to solve a problem that when a conventionalsteel cable strength detection device is used for detecting a steel cable, one section needs to be wound and fixed and then is clamped for stretching detection, so the tensile strength detection result is affected due to the fact that the winding position is prone to abrasion during tensile detection, a steel cable is prone to disengagement in the pressurizing and stretching process due to the fact that only a hydraulic clamping mode is adopted, and in the steel cable detection process, when the steel cable breaks off a steel wire, surrounding detection personnel are prone to being injured bybreakage. The device comprises a detection bench, and a control computer is fixedly mounted at the right end of the side wall of the front end of the detection table. Due to the fact that the hydraulic mechanism body is the electric air cylinder, torque changes of the left end of the connecting rod can be detected through the load sensor, then detection signals are converted into electric signalsthrough the photoelectric encoder, the electric signals are transmitted to an external control computer to be collected and recorded, and accurate data reference is provided for strength detection.

Description

technical field [0001] The invention relates to the technical field of steel cable strength detection, and more specifically relates to a steel cable strength testing device for coal equipment. Background technique [0002] The significance of steel cable detection is to accurately and truly reflect the quality status of the steel wire rope, so as to predict the life of the steel wire rope, avoid potential safety hazards, and ensure safe production. And scientifically guide the rope, thereby prolonging the service life of the wire rope. [0003] For example, a steel cable tension detection device in the patent application CN201621134735.4 includes a bracket, the upper end of the bracket is provided with a roller, the two ends of the rotating shaft of the roller are fixed on the fixed seat, and one end of the fixed seat is hinged and fixed on the bracket. A force transmission frame is arranged on the lower end surface of the seat, a pressure sensor is arranged directly below...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a steel cable strength testing device for coal equipment to solve the conventional steel cable strength testing device. When sticking to the steel cable, it is necessary to wrap and fix a section before clamping to perform tensile testing. , and the winding position is prone to wear during tensile testing, thus affecting the tensile strength testing results, and the simple hydraulic clamping method will easily cause the steel cable to detach during the pressurized stretching process. In addition, the steel cable During the detection process, when the steel cable breaks the steel wire, it is easy to collapse and injure the personnel around the detection
