Problems solved by technology

At present, the test devices of relevant departments in our country can only test the main technical indicators, high and low temperature, heat and humidity changes, and work stability of the electro-hydraulic control system components such as control devices, power adapters, and electromagnetic drives. The test method cannot detect the system stability and real-time dynamics of each component when it is running as a whole

Embodiment Construction

[0013] The present invention will be further described below in conjunction with drawings and embodiments.

[0014] Such as figure 1 , the test device of the hydraulic support electro-hydraulic control system mainly includes three parts: the control of the operation relationship of the three machines in the fully mechanized mining face, the simulation of the environmental conditions of the fully mechanized mining face, and the hardware and software of the measurement and control system. Test principle: put the electro-hydraulic control system under test in the three-machine operation system, and use the measurement and control system to test the electro-hydraulic control system under test in the coal mine underground environment such as rain, vibration, and electromagnetic interference by simulating the environment of the fully mechanized mining face. System functions, technical indicators, safety and reliability, anti-interference, fault alarm and diagnostic characteristics a...

Abstract

The invention relates to a hydraulic support electro-hydraulic control system testing device, which mainly comprises three parts such as fully-mechanized coal mining working face three-machine operating relation control, fully-mechanized coal mining working face environmental condition simulation and system hardware and software measurement and control. The hydraulic support electro-hydraulic control system testing device can perform detection and inspection on a tested sample on the aspects of system functions, technical performance, working stability, safety, interference resistance, reliability and the like without damaging the tested sample. A testing platform is of an operating condition that a hydraulic support, a coal mining machine and a scarper conveyer operate in a coordinated manner, so that service conditions of an electro-hydraulic control system in a coal mine underground can be simulated to the maximum extent. Assessment for the hydraulic support electro-hydraulic control system is completed strictly according to safety standard specifications and national standards.

Description

technical field [0001] The invention relates to a test device for an electro-hydraulic control system of a hydraulic support, which is suitable for the mechanical field. Background technique [0002] With the development of coal mining technology, various advanced technologies are gradually applied to the hydraulic support control system, forming an automatic control system for the hydraulic support of the fully mechanized mining face. Since 2005, the technology of domestic hydraulic support electro-hydraulic control system has developed rapidly. As a product registered in the Office of Mining Product Safety Mark, the type inspection of hydraulic support electro-hydraulic control system is a necessary assessment link for products to be used in coal mines. At present, the test devices of relevant departments in our country can only test the main technical indicators, high and low temperature, heat and humidity changes, and work stability of the electro-hydraulic control syste...
