[0029] The upper and lower surfaces of the support base 5 are provided with hydraulic support sockets 20, the left and right side walls of the support base 5 are provided with pin holes I19 communicating with the hydraulic support sockets 20, and the ends of the hydraulic support 6 are provided with left and right side walls of the support base (5). The upper pin hole I (19) is matched with a through hole, and a pin rod is inserted between the through hole and the pin hole I19. Compared with the insertion structure between the hydraulic prop 6 and the support base 5 that those skilled in the art can think of, this structure is simpler and more effective.
[0030] The inner side of the bracket base 5 is provided with U-shaped grooves I21 which are clamped on the upper and lower surfaces of the slider 16 and the outer side. The outer side of the bracket 5 is provided with an assembly hole I22, and the outer side of the slider 16 is provided with an assembly hole I22 on the bracket b...

The invention specifically relates to a tunnel quick-tunneling advance support integrated device, which solves the problems of low working speed, low speed, narrow application range and incapability of quickly punching an anchor rod of the advance support device in the traditional tunnel quick tunneling process. The tunnel quick-tunneling advance support integrated device comprises two parallel sliding rails. Three door type brackets are arranged on the sliding rails in parallel from front to rear. An anchor rod punching bracket is fixed on the front ends of the sliding rails. An anchor rod punching transverse beam is connected between the tops of two hydraulic cylinders of the anchor rod punching bracket. A plurality of anchor rod machine head installation chassis are uniformly arranged on the anchor rod punching transverse beam. A plurality of front detecting beams are horizontally arranged on the front side surface of the door type bracket I. A rail base II fixed with a sliding block of the door type bracket III is sleeved on the inner track of the sliding rail. A push hydraulic cylinder is connected between a rail base I and the rail base II. The rail base I and the door type bracket I are in sliding detachable connection. The tunnel quick-tunneling advance support integrated device disclosed by the invention has the advantages of smart and rational structure, reliable performance, simple and convenient installation, convenient operation and wide application tunnel range.
Description
Technical field [0001] The invention relates to a supporting device during the driving of a well, in particular to a comprehensive device for supporting and supporting of the quick excavation of the well. Background technique [0002] The most important method of roadway rapid excavation in our country is the cantilever roadheader and MQT series bolt drill, SPJ-650 belt conveyor supporting technical operation line, also known as comprehensive mechanized roadway excavation, but the level of comprehensive excavation is still hovering. At about 350 meters. The safety problem of advance temporary support for roadway excavation is a technical problem that has plagued coal mine production for many years. The temporary support forms commonly mentioned in the excavation of domestic coal mine roadways are suspension ring (U-shaped clamp) string beam and pillar plus beam support. Both of these two methods are safe and unreliable, difficult to operate, and support. The use of one digging ...
