Intelligent self-adaptive advanced hydraulic support frame

Abstract

The invention discloses an intelligent self-adaptive advanced hydraulic support frame and an automatic intelligent support process flow thereof. A main body structure of the support frame comprises abase, supporting columns, a posture-adjusting combined top beam and a rotatable top beam resetting device; an intelligent self-adaptive control system comprises a base three-way tilting angle sensor,a main body top beam three-way tilting angle sensor, a supporting top beam three-way tilting angle sensor, a supporting column pressure sensor, a height adjusting oil cylinder pressure sensor and a supporting pressure adjusting oil cylinder pressure sensor. Based on the main body structure of the intelligent self-adaptive advanced hydraulic support frame and the intelligent self-adaptive control system, the advanced hydraulic support frame can adjust the support posture in real time according to the deformation of surrounding rock of a roadway and be kept in the best support state, and the problems are solved that when traditional advanced hydraulic supports are in bearing unbalanced loading state, the posture cannot be automatically adjusted according to the deformation of the surroundingrock of the roadway, and unbalanced loading easily occurs, so that column pin shafts are broken and top beams shed; the support effect of the advanced hydraulic support frame of the roadway is effectively improved.

Description

technical field [0001] The invention relates to an advanced hydraulic support for coal mines, in particular to an advanced hydraulic support that can automatically adjust the support posture according to the deformation of the roadway surrounding rock so that the hydraulic support is always in the best support state, which can effectively improve the performance of the advanced hydraulic support. The adaptability and support effect of roadway surrounding rock deformation. Background technique [0002] Article 97 of the "Coal Mine Safety Regulations" stipulates that all safety exits in the coal mining face and the joints of the roadway must be strengthened in the area affected by the advanced pressure, and the length of the roadway with reinforced support must not be less than 20m. The traditional roadway advance support technology generally uses wooden props or single hydraulic props for support. This support method has problems such as low support strength, low efficiency, ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an intelligent self-adaptive advanced hydraulic support that can adjust the support posture of the advanced hydraulic support in real time according to the deformation of the surrounding rock of the roadway, which solves the problem that the traditional advanced hydraulic support cannot be adjusted in real time according to the deformation of the surrounding rock of the roadway, which causes the support Problems such as poor connection effect of the top beam, poor bearing state, prone to breakage of the top beam pin, low support efficiency, etc.
