Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
As shown in fig. 1 to 3, the invention comprises a supporting beam, a supporting seat, a sliding supporting beam 7 and a sliding bottom beam 8; the supporting beam and the supporting seat are fixedly connected through a plurality of upright posts; the support beam comprises a front support beam 1 and a rear support beam 3; one or more middle support beams 2 are arranged between the front support beam 1 and the rear support beam 3; the adjacent support beams are connected through a sliding support beam 7; the slide support beam 7 can be extended or contracted in the horizontal direction.
The support seat comprises a front support seat 4 and a rear support seat 6; one or more middle supporting seats 5 are arranged between the front supporting seat 4 and the rear supporting seat 6; the front support seat 4, the middle support seat 5 and the rear support seat 6 are respectively in one-to-one correspondence with the front support beam 1, the middle support beam 2 and the rear support beam 3; the adjacent supporting seats are connected through a sliding bottom beam 8, and the sliding bottom beam 8 can synchronously extend or retract with the sliding supporting beam 7 along the horizontal direction; one or two suspension hydraulic struts 9 are arranged between the opposite sliding bottom beams 8 and the sliding supporting beams 7.
The front end of the front supporting seat 4 and the rear end of the rear supporting seat 6 are respectively provided with a hydraulic jack 10. The hydraulic jack at the front end of the front supporting seat 4 is connected with the scraper conveyor 13 at the front side of the front supporting seat and is used for pushing the scraper conveyor 13 forwards and pulling the front part of the composite hydraulic support to move forwards; the upper end of the scraper conveyor 13 is provided with a coal mining machine 12; the hydraulic jack at the rear end of the rear supporting seat 6 is connected with the packing conveyor at the rear side of the rear supporting seat and is used for pushing the rear part of the composite hydraulic support to move forward and driving the packing conveyor to move forward.
The specific working principle of the invention is as follows: when the coal mining machine advances forwards, the part of the front part of the composite hydraulic support for providing coal mining space support moves forwards, the sliding support beam 7 and the sliding bottom beam 8 extend out along the horizontal direction, and the suspension type hydraulic support column 9 is put down until the composite hydraulic support is completely transformed into an extension form (shown in figure 2); filling operation at the rear end of the bracket can be performed simultaneously when the coal mining machine is used for mining coal, so that independent mining and filling are realized;
when the filling operation of the rear end of the support is completed and needs to be pushed forward further, the suspension type hydraulic support 9 is retracted, the sliding support beam 7 and the sliding bottom beam 8 are contracted, and the traction drives the part of the rear part of the composite hydraulic support for providing the filling operation space to be pushed forward (as shown in fig. 3), so that the whole process is completed, and the circulation is performed in the whole mining process.
The coal mining machine is used for coal mining, and meanwhile, filling operation is also carried out simultaneously. When the coal mining machine is pushed forward and the filling operation at the rear end is not completed, the support stretches, so that the normal pushing of the coal mining machine is ensured and the filling operation is not influenced; when the filling operation part needs to be pushed forward, the support contracts and approaches to the direction of the coal mining machine. Thus, coal mining and filling are performed simultaneously and independently of each other. In the coal mining process, according to the coal cutting operation speed and the filling operation speed of the coal mining machine, the support can adaptively adjust the support distance, and the adaptive support range is four times of the feed size.
The invention can not only provide the bracket space in front of the bracket, namely in the direction of the coal mining machine, but also provide the supporting space in back of the bracket, namely in the direction of the goaf; the middle support beam, the sliding bottom beam and the suspension type hydraulic prop are utilized to support the middle space, so that the contradiction between mining and filling is alleviated, the purpose of independent mining and filling operation is achieved, and meanwhile, necessary conditions are provided for intelligent mining.
The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, but is also intended to be limited to the following claims.
