Abstract

The invention relates to a detection device of a mine vehicle, in particular to a hydraulic tension tester for a connecting device of the mine vehicle. The hydraulic tension tester is used for quality detection of the connecting device of the mining transportation vehicle. According to the technical scheme, the hydraulic tension tester is characterized by comprising mine vehicle tracks, a test bed frame, a movement mechanism and a hydraulic system, wherein the test bed frame is arranged between the mine vehicle tracks, the horizontal height of the test bed frame is smaller than the height of the mine vehicle tracks, and hydraulic system fixing bases are arranged below the two ends of the test bed frame. The hydraulic tension tester for the connecting device of the mine vehicle can be used for independently completing self-inspection of the mine vehicle in a coal mine enterprise, inspecting the connecting device of the mine vehicle in use on schedule and verifying whether the bearing capacity of the connecting device of the mine vehicle accords with related safety requirements, and consequently the safety performance can be guaranteed.

Description

technical field [0001] The invention relates to a mine car detection device, which is used for the quality detection of the coal mine transport vehicle connection device. Background technique [0002] The connecting device of the mine car is an important safety component, and its quality, performance and usage status are related to the safety performance of the transport vehicle. According to the analysis of relevant data, the fracture of the connecting device is one of the main reasons for the accident of the sports car in the inclined road, and the quality of the performance index of the connecting device of the mine car is related to the transportation safety of the inclined road. Therefore, in order to ensure the safety of the lifting and transportation of the mine car, verify whether the bearing capacity of the mine car hitch meets the relevant safety regulations, ensure the safety of the mine car during lifting and transportation, and avoid long-term use of the mine ca...
