Problems solved by technology
[0003] At present, hydraulic support products such as single hydraulic props, rotor hydraulic props and hydraulic jacks are widely used underground, and there are reasons such as leakage of liquid or changes in geological structure, the friction between the prop and the top beam, the ground friction becomes smaller or serious overpressure This will cause the pillar to collapse due to loss of support, or the pillar will be damaged due to overpressure, causing the top beam to collapse, which will easily cause personal casualties and property losses
In order to prevent the accident, the underground security personnel need to frequently check the supporting force of the hydraulic props, and check the supporting friction force of the props one by one by shaking or beating and other very outdated means. At the same time, a lot of time and energy are wasted, and it is impossible to understand the current working status of the hydraulic prop in time.

The invention relates to a wireless monitoring fully mechanized mining hydraulic support, which can detects the pressure of an underground mining supporting device and control and adjust the current state of the supporting device in real time, and simultaneously can realize an over pressure or low pressure alarming function. The wireless monitoring fully mechanized mining hydraulic support realizes non-pressure or over pressure alarming by monitoring and detecting the pressure of a liquid medium in an upright column in real time, adjusting the working condition of the supporting device according to the current pressure condition, and simultaneously forming an alarming circuit according to a preset pressure value, so the wireless monitoring fully mechanized mining hydraulic support is a device which integrates detection, control, early warning and alarming and ensures the normal running of a mining working surface supporting device; besides, the wireless monitoring fully mechanized mining hydraulic support can automatically monitor the load supporting force of a hydraulic supporting point, and can provide a powerful guarantee for avoiding underground safety accidents.
Description
technical field [0001] The invention relates to a wireless monitoring fully mechanized mining hydraulic support. Background technique [0002] With the progress of the times and the development of electronic information technology, the requirements for personal safety and property safety of underground mining work are also constantly increasing. The single hydraulic prop that is still widely used in the underground mining process is an important guarantee for the personal safety of underground mining workers. [0003] At present, hydraulic support products such as single hydraulic props, rotor hydraulic props and hydraulic jacks are widely used underground, and there are reasons such as leakage of liquid or changes in geological structure, the friction between the prop and the top beam, the ground friction becomes smaller or serious overpressure This will cause the pillar to collapse due to loss of support, or the pillar will be damaged due to overpressure, causing the top ...
