Description

Supporting structure of fully-mechanized caving face coal rock roof Technical Field The utility model belongs to the technical field of supporting equipment of a coal rock roof, and particularly relates to a supporting structure of a fully-mechanized caving face coal rock roof. Background The coal rock roof support of the comprehensive working face is an important work in coal mine production, and as the top of the coal face is usually a layer of huge rock or coal bed, the substances are very fragile and often have an aquifer, the substances are often influenced by the ground pressure and vibration suffered by mining equipment during working, and once the condition of improper or untimely support occurs, roof collapse and accidents can be caused, and the roof is protected by a hydraulic support method at present; However, the existing supporting structure of the fully-mechanized caving face coal rock roof adopts hydraulic telescopic upright posts to support the top beam, and each hydraulic telescopic upright post is independently supported, when the top beam is pressed, the upright posts pressed for a long time are damaged easily due to uneven stress, so that the top beam is unbalanced and isolated from each other, the interlocking effect is caused, the large-area supporting failure is caused, and the roof fall accident occurs. Disclosure of utility model Aiming at the situation, in order to overcome the defects of the prior art, the supporting structure of the fully-mechanized caving face coal rock roof provided by the utility model effectively solves the problems that the supporting structure of the fully-mechanized caving face coal rock roof supports a top beam by adopting hydraulic telescopic upright posts, each hydraulic telescopic upright post is independently supported, when the top beam is stressed, the upright posts stressed unevenly and stressed for a long time are easy to damage, and the top beam is unbalanced. The supporting structure of the fully-mechanized caving face coal rock roof provided by the utility model comprises a base, a top seat and a supporting structure, wherein the supporting structure is arranged between the base and the top seat and plays a role of balanced supporting, the supporting structure also comprises a balanced supporting unit and a lifting supporting unit, the balanced supporting unit is arranged below the top seat, and the lifting supporting unit is arranged above the base and fixedly connected with the balanced supporting unit; The balance support unit further comprises a support pad and a pressure sensor, the support pad is fixedly arranged below the footstock, the pressure sensor is fixedly arranged below the support pad, the support seat wraps the lower half section of the pressure sensor and is fixedly arranged, and the connecting seat is fixedly arranged at the bottom of the support seat. Preferably, the lifting support unit further comprises a limiting pin, a limiting seat and a hydraulic telescopic rod, wherein the limiting pin is fixedly arranged above the base, the limiting seat is inserted on the limiting pin and is supported on the base, one end of the hydraulic telescopic rod is fixedly arranged above the limiting seat, and the other end of the hydraulic telescopic rod is fixedly arranged below the connecting seat.
