Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The following describes a narrow fuselage large section eight-arm anchor assembly 1000 according to an embodiment of the present invention with reference to the accompanying drawings. As shown in fig. 1 to 12, the narrow-fuselage large-section eight-arm bolting rig 1000 according to the embodiment of the invention includes a mining device, a narrow-fuselage large-section eight-arm bolting rig 100, and a power car 500.
The mining apparatus includes a heading machine 200, a bridge conveyor 300, and a belt conveyor 400. The bridge conveyor 300 is engaged with the heading machine 200, and the belt conveyor 400 is engaged with the bridge conveyor 300.
The eight-arm anchor drill carriage 100 with the narrow-fuselage large support section comprises a carriage body 10 and an anchor device, wherein the anchor device comprises an anchor drill frame and a drill frame moving device, the drill frame moving device is rotationally connected with the carriage body 10, and the rotating shaft of the drill frame moving device is in the up-down direction. The drill frame moving device is connected with the anchor drill frame so as to drive the anchor drill frame to rotate in the horizontal direction. The power car 500 comprises a pump station 510, and the pump station 510 is connected with the eight-arm anchor drill carriage 100 with the large support section of the narrow fuselage through a pump pipe 520.
In the related technology, most of domestic coal mines are tunneled in a single roadway, the roadway width is generally 4-6 m, and because the whole machine of the anchor rod drill carriage is too wide (the anchoring device cannot shrink), the traditional anchor rod drill carriage cannot be moved to the front of the roadway to be anchored and protected through the tunnelling device, the belt conveyor and the bridge transfer conveyor, and each time the anchoring device is required to be withdrawn from the roadway or the anchoring is carried out in a manual hand-held single anchor rod drilling machine mode, so that popularization and application of the anchor rod drill carriage are greatly limited.
The mining device can carry out tunneling mining on the roadway. Specifically, after the heading machine 200 cuts the roadway, crushed rock is transported to the outside of the roadway through the bridge type reversed loader 300 and the belt conveyor 400. After the heading machine 200 has advanced a predetermined distance, it is necessary to anchor the newly-tunneled area. As shown in fig. 1 to 12, the following description will be made specifically with the longitudinal direction of the narrow-body large-support-section eight-arm anchor-boom drill carriage 100 as the front-rear direction, and the width direction of the narrow-body large-support-section eight-arm anchor-boom drill carriage 100 as the left-right direction.
The anchoring device of the eight-arm anchoring drill carriage 100 with the narrow-body large support section comprises an anchoring drill frame and a drill frame moving device. The boom moving means is rotatably connected to the body 10, and the rotational axis of the boom moving means is in the up-down direction, so that the boom moving means rotates in the horizontal direction. The drill frame moving device is connected with the anchor drill frame so as to drive the anchor drill frame to rotate in the horizontal direction. That is, the anchor boom is rotatable in the horizontal direction about the boom moving means rotation axis, so that the position of the anchor boom in the left-right direction can be changed so that the anchor device is contracted toward the inside of the vehicle body 10 in the width direction of the vehicle body 10. For example, the mobile anchor boom is retracted inwardly as it passes through the narrower width region, thereby reducing the overall width of the narrow fuselage large support section eight-arm anchor rig 100. So that the eight-arm anchoring drill carriage 100 with the narrow-fuselage large supporting section passes through the space between the mining device and the roadway to reach the area to be anchored, the mining device is not required to be withdrawn from the roadway or the manual handheld single-body type jumbolter is not required to be anchored, the anchoring efficiency is improved, and the anchoring is more flexible and convenient. After the eight-arm anchor drill carriage 100 with the large support section of the narrow machine body reaches an anchor protection area, the anchor protection drill carriage matched with the eight-arm anchor protection drill carriage can rotate to a proper position through the drill carriage moving device, so that the anchor protection drill carriage is convenient for carrying out anchor bolt support on the top of a roadway.
Since lowering the narrow-fuselage large-section eight-arm anchor drill carriage 100 requires space for moving the anchor drill carriage into the vehicle body 10, and requires the width of the vehicle body 10 to be narrow (requires the vehicle body 10 to be able to pass through the space between the mining apparatus and the roadway), the space of the power mechanism of the narrow-fuselage large-section eight-arm anchor drill carriage 100 is encroached. The pump station 510 of the power car 500 is connected with the eight-arm anchor drill carriage 100 with the large support section of the narrow fuselage through a pump pipe 520, so as to provide power for the movement and the anchor of the eight-arm anchor drill carriage 100 with the large support section of the narrow fuselage.
Therefore, the eight-arm anchoring unit 1000 with the narrow-fuselage large-support section according to the embodiment of the application has the advantages of more convenient and flexible anchoring and improved anchoring efficiency.
