Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] Such as Figure 1~5 Shown is the main structure of an intelligent self-adaptive advanced hydraulic support of the present invention, including: a base 1 , a support column 2 , a posture adjustment combined top beam 3 , and a top beam rotatable reset device 4 .
[0033] The base 1 and the support column 2 are connected and fixed through the clamp 5, so that the support column 2 and the base 1 are connected as a whole.
[0034] The support column 2 adopts a split design, including a column ball head 21 and a column body 22, wherein the diameter of the column ball head 21 should be greater than the cross-sectional diameter of the column body 22, and the column ball head 21 and the column body 22 are connected by built-in bolts.
[0035] The posture adjustment combined top beam 3 includes a main body top beam 31, a stable top beam 3...

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, ...
