Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to an advance support which moves automatically together with a transfer machine. Background Art

[0002] The coal mining face is generally dropped by a coal mining machine, and the cut coal is transported to the transfer machine by a scraper conveyor, and then to the belt conveyor by the transfer machine, and finally transported to the ground by the belt conveyor. In order to meet the demand for the continuous shortening of the belt conveyor caused by the continuous advancement of the working face, it is necessary to install a retractable self-moving device separately on the tail of the belt conveyor. my country's "Coal Mine Safety Regulations" clearly stipulates that all safety exits of the coal mining face and the connection between the tunnel must be strengthened within the influence range of the advance pressure, which is called advance support, and the length of the tunnel with enhanced support shall not be less than 20m. Due to the separate installation of the retractable self-moving device, the space in this area is tight, and it is difficult to deploy advance hydraulic supports for surrounding rock support.

[0003] The Chinese invention patent with application number 202310003712.8 discloses an integrated device for automatic pushing and advanced support of the tail of a belt conveyor, which mainly includes a first support bracket, a second support bracket, a first pushing jack, a second pushing jack, a first fixed beam, a second fixed beam, and a bottom support plate; the upper ends of the first support bracket and the second support bracket are connected by the first fixed beam and the second fixed beam respectively, and the lower ends of the first support bracket and the second support bracket are fixedly connected by the bottom support plate; one end of the first pushing jack and the second pushing jack are connected to one end of the first support bracket and the second support bracket respectively, and the other end is connected to the advanced hydraulic support of the working face chute. The present invention not only realizes the pulling and horizontal adjustment of the tail of the belt conveyor, but also realizes the effective support of the surrounding rock in the area, and effectively solves the problem of surrounding rock control and directional movement in the tail area of ​​the belt conveyor.

[0004] In order to solve the problem that the first supporting bracket and the second supporting bracket are easy to tip over when they move independently, the first supporting bracket and the second supporting bracket are connected by the first fixed beam, the second fixed beam and the bottom support plate to form a stable pushing support device. The pushing support device and the advance hydraulic support are moved alternately. Since the first supporting bracket and the second supporting bracket are relatively fixed by the first fixed beam and the second fixed beam, the first supporting bracket and the second supporting bracket will simultaneously detach from the top of the supporting tunnel when moving, resulting in excessive leakage area of ​​the tunnel roof.

[0039] Running process:

[0040] In the initial state, the first unit bracket 211, the second unit bracket 212, the third unit bracket 213, and the fourth unit bracket 214 are all supported, the first telescopic member 221, the second telescopic member 222, the third telescopic member 223, the fourth telescopic member 224, the fifth telescopic member 225, the sixth telescopic member 226, the seventh telescopic member 52, the eighth telescopic member 62, and the ninth telescopic member 72 are all retracted, and the tenth telescopic member 53 is extended;

[0041] The tenth telescopic member 53 contracts, and the seventh telescopic member 52 extends, pulling the slider 51 and the loader forward. The seventh telescopic member 52 can press the slider 51 to prevent the slider 51 from tilting. The loader moves linearly relative to the slider 51 under the action of the two third guide members 56.

[0042] The tenth telescopic member 53, the first telescopic member 221, and the second telescopic member 222 extend together, and the seventh telescopic member 52 contracts;

[0043] The first unit bracket 211 is retracted and disengaged, the first telescopic member 221 is retracted, the third telescopic member 223 and the eighth telescopic member 62 are extended, the first unit bracket 211 moves forward, the fifth telescopic member 225 is extended, and rotates relative to the first unit bracket 211 to maintain the first unit bracket 211 in an upright state. After the first unit bracket 211 is in place, it is supported and the first unit bracket 211 moves linearly relative to the slider 51 under the action of the first guide member 61;

[0044] The second unit bracket 212 is retracted and disengaged, the second telescopic member 222 is retracted, the fourth telescopic member 224 and the ninth telescopic member 72 are extended, the second unit bracket 212 moves forward, the fifth telescopic member 225 is shortened and rotates relative to the second unit bracket 212 to maintain the second unit bracket 212 in an upright state, and the second unit bracket 212 is in place and supported, and the second unit bracket 212 moves linearly relative to the slider 51 under the action of the second guide member 71;

[0045] The third unit bracket 213 is retracted and disengaged, the third telescopic member 223 and the eighth telescopic member 62 are retracted, the third unit bracket 213 moves forward, the sixth telescopic member 226 is extended, and rotates relative to the third unit bracket 213 to maintain the third unit bracket 213 in an upright state. After the third unit bracket 213 is in place, it supports the top, and the third unit bracket 213 moves linearly relative to the slider 51 under the action of the first guide member 61;

[0046] The fourth unit bracket 214 is retracted and unloaded, the fourth telescopic member 224 and the ninth telescopic member 72 are retracted, the fourth unit bracket 214 moves forward, the sixth telescopic member 226 is retracted, and rotates relative to the fourth unit bracket 214 to maintain the fourth unit bracket 214 in an upright state.

[0047] When any unit support moves forward and removes the roof, there are three unit supports to support the top, which reduces the area of ​​the roof leaking on the top of the tunnel.

[0048] When any one unit bracket moves, the other three unit brackets are fixed relative to the slider 51. The first guide member 61 or the second guide member 71 can always ensure a linear relationship with the slider 51. The slider 51, the loader, and the unit brackets always maintain relative linear movement during the relative movement.

[0049] At least three of the four unit brackets support the top, and the first telescopic member 221, the second telescopic member 222 and the tenth telescopic member 53 form a guiding effect on each other, which is conducive to the slider 51, the loader and the unit bracket to always maintain relative linear movement during the relative movement.
