Abstract

The invention discloses a circulating tunneling immediate support device and method. The circulating tunneling immediate support device comprises a walking mechanism, a sliding mechanism and an independent supporting mechanism; the independent supporting mechanism comprises supporting units arranged in the roadway tunneling direction from front to back; a longitudinal forepoling bar and a protection net hydraulic cylinder are arranged in front of the first supporting unit and connected with the first supporting unit, and the lower end of the longitudinal forepoling bar is connected with a cross forepoling bar and a hydraulic supporting column; the last supporting unit is provided with a frame moving seat, a rear hinging cross beam and a corresponding hydraulic supporting column are arranged behind the tail supporting unit, and a sliding hydraulic oil cylinder is arranged between the frame moving seat and the rear hinging cross beam; each supporting unit comprises a supporting hinging cross beam, supporting stand columns are arranged under the supporting hinging cross beam respectively, and inner sliding rods and sliding ways penetrating through the first supporting unit are arranged in the roadway tunneling direction; each supporting unit is provided with parallel hydraulic oil cylinders. The circulating tunneling immediate support device is compact in structure, and has the advantages that work efficiency is high, and time and labor are saved; frames can be automatically moved in a marching mode.

Description

technical field [0001] The invention relates to a circular excavation timely support device and a method thereof. Background technique [0002] With the rapid development of coal mining technology, coal mining gradually realizes mechanization and automation of production. The practical experience at home and abroad for many years shows that the anchoring support of coal roadway surrounding rock has significant advantages. In the roadway excavation construction process, the efficiency of mechanized excavation is high, but the support speed of the roadway lags far behind the excavation speed. [0003] The existing parallel operations cannot meet the requirements. First, the degree of mechanization is very low and a large amount of manpower is required, resulting in low production efficiency and high costs; [0004] The 2nd, existing parallel operation all is a single movement, can not realize automatic step-by-step moving frame. [0005] In the current mining, especially in ...
