Description

Technical Field

[0001] The present invention relates to the technical field of coal industry, and particularly to a moving device for a multi-category drill rig platform in roadway tunneling. Background Art

[0002] At present, the single roadway tunneling process of using a roadheader to cut coal and a single-anchor bolt drill rig for support is commonly adopted in coal mine roadway tunneling faces. When switching between the tunneling and support processes, it is often necessary to move the temporary support and the single-anchor bolt drill rig back and forth. This not only increases the labor intensity of workers, but also occupies the normal tunneling cycle time and reduces the roadway forming speed. The forms of temporary support adopted in coal mine roadway tunneling faces include forms such as point columns plus crossbeams and pipe-roof forepoling beams. The permanent support equipment includes single hydraulic anchor bolt drill rigs, single pneumatic anchor bolt drill rigs, etc. Among them, for point columns plus crossbeams, personnel need to enter the roof control area to operate, which has a relatively high risk, and the labor intensity of personnel is large, the time consumption is long, and the operation is complex; multi-category drill rig platforms have not been widely used in coal mines like fully-mechanized supports. The main reason is that multi-category drill rig platforms need to move back and forth. For example, after tunneling is completed, they need to be moved to the heading face for support operations. After the support operation is completed, the multi-category drill rig platform needs to be placed at a position about 15 meters away from the heading face during tunneling so as not to affect the normal tunneling of the roadheader; as described above, a multi-category drill rig platform needs to be moved twice in a normal cycle. The long moving time and the non-linear moving trajectory are prone to damage the roof anchor cables and rib bolts, which have always been two core problems disturbing the use of multi-category drill rig platforms; for solving the moving problem of the equipment for switching between tunneling and support processes, many methods have emerged in China. Representative ones include single-body cross-step self-shifting supports and roadheader-mounted mobile temporary support brackets. The single-body cross-step self-shifting support occupies a large space. When the floor is uneven and there is coal and rock at the tunneling heading face, it is difficult to self-shift, and repeated support damages the roof and deteriorates the support conditions. The roadheader-mounted mobile temporary support bracket has complex alignment between the roadheader and the support, and the slow moving speed of the roadheader-mounted mobile occupies a long normal cycle time, etc., and thus cannot meet the requirements of rapid temporary support. Therefore, how to ensure the rapid and stable movement of the temporary support bracket within a range of 20 meters at the heading face and ensure timely and safe support for the empty roof is a difficult problem to be solved by the present invention.

In this embodiment, preferably, the track plate 102 is a channel steel (of course, the form of the track plate 102 is not limited).

[0056] In this embodiment, preferably, the vehicle body driving part includes: a trolley platen 116, a sprocket mechanism, a gear mechanism 106, a bearing mechanism, and a transmission shaft 109; sliding parts adapted to the track structure 119 are arranged on both sides of the trolley platen 116 (preferably, each sliding part forms a downward-opening chute through a pressing plate); the transmission shaft 109 is arranged on the lower surface of the trolley platen 116 through the bearing mechanism; the sprocket mechanism is fixed on the transmission shaft 109; a gear mechanism 106 is arranged at the end of the transmission shaft 109; a rack mechanism 105 is arranged on the lower surface of the upper backing plate 104 of the track structure 119, and the gear mechanism 106 meshes with the rack mechanism 105.

The balancing sprocket 115 is used for cooperating with the balancing sprocket 115 of another set of transmission shafts 109. Bearing mechanisms (a middle bearing seat 107 and bearings 108, bearing seats 112 and bearings 113 at both ends) are installed in the middle and at both ends of the transmission shaft 109 respectively, and the bearing seat 107 is installed on the bottom surface of the trolley platen 116. A gear mechanism 106 is installed at the end of the transmission shaft 109. It can be understood that

[0057] Preferably, at the gaps between several sections of tracks, in order to ensure a smooth transition through several sections of tracks, a clutch is provided in the vehicle body driving part. At the gaps between several sections of tracks, the gap and angle problems existing at the joints can be overcome through a semi-coupled state; for the clutch, at this time, the driving sprocket 112 on the transmission shaft 109 is replaced by a kind of driving gear, and a clutch is installed on this driving gear. The driving gear meshes with the output gear of the motor, and the function of the clutch is to realize the separation and engagement between the driving gear and the output gear of the motor.

[0058] In this embodiment, preferably, the vehicle-carrying part includes: a trolley platen 116 and a positioning frame 117; sliding parts adapted to the track structure 119 are provided on both sides of the trolley platen 116; the positioning frame 117 is arranged on the upper surface of the trolley platen 116.

[0062] Embodiment Two

[0063] Combined with Figure 14 、 Figure 15 As shown, this embodiment provides a roadway tunneling device, including: a roadheader, a multi-category drill platform and the moving device for the multi-category drill platform in roadway tunneling described in Embodiment One; an adjusting bracket is installed on the cutting part of the roadheader, the adjusting bracket is connected with a section of track structure, a section of track structure is installed on the fuselage guard plate part of the roadheader, a section of track structure is installed on the belt conveyor part of the roadheader, the self-propelled trolley can walk on each track structure, and the multi-category drill platform is installed on the self-propelled trolley.

[0064] Among them, the track of the belt conveyor section is welded on the second conveyor frame, and a frame-shaped support is welded every meter. The support of the transition section connecting the second conveyor section and the full-face roadheader is welded on the second conveyor dragging frame to prevent the tail roller of the belt conveyor from being bent during the movement of the support.

[0065] Among them, there is no gap in the track rack within each of the three sections, but there are gaps in the two overlapping parts between the three sections. Since the track of the guard plate part is fixed on the full-section roadheader, during the coal cutting process of the full-section roadheader, the belt conveyor will rotate as the angle of the full-section roadheader changes. Therefore, there should be a gap between the belt conveyor part and the guard plate part to accommodate this rotation.

[0066] Among them, the track of the fuselage guard plate section is fixed. During the coal cutting process of the cutting section, there are swings up and down and also left and right. Therefore, there is also a gap between the track of the guard plate section and the cutting section to meet the needs of the coal cutting swing.

[0067] Of course, the existence of the above-mentioned gap does not affect the passability of the moving device.

[0068] In summary, the working principle of this roadway tunneling equipment is as follows:

[0069] After the full-section roadheader finishes coal cutting, first straighten the fuselage to make the roadheader in the middle position of the roadway. Adjust the track angle of the cutting section so that the track of this section is in the same plane as the guard plate part. Then, operate the two-stage leveling valve group at the belt conveyor to lower the four oil cylinders set at the belt conveyor to the solid bottom, so that the track of the belt conveyor section is in the same plane as the guard plate part. At this time, the trolley on the upper surface track of the belt conveyor can be driven by the motor to the lower part of the multi-category drill platform. Retract the support legs of the multi-category drill platform to make the multi-category drill platform smoothly land on the carrying part of the trolley and be reliably positioned. Then drive the trolley to push the multi-category drill platform to the newly exposed roof, extend the support legs of the multi-category drill platform to disconnect the multi-category drill platform from the trolley, and then retreat the roadheader to make room for support. After the support is completed, the crawler of the full-section roadheader drives into the lower part of the above-mentioned multi-category drill platform for unloading, retract the support legs of the multi-category drill platform so that it just lands on the carrying part of the trolley, drive the trolley to move the multi-category drill platform to a place where it does not affect tunneling, and then raise the multi-category drill platform to disconnect the multi-category drill platform from the trolley. Then start tunneling.

[0070] This embodiment provides a structure of a multi-category drill platform. Of course, the form of the multi-category drill platform is not limited and can be flexibly adjusted according to actual needs.

[0071] For example: The multi-category drill platform includes: a hazard relief drilling mechanism, which serves as an automatic drilling system for roadway tunneling disasters. The hazard relief drilling mechanism is arranged on the self-propelled trolley and can move on the track in a foldable form, used for drilling holes to detect water and gas, realizing the mechanization and automation of the mechanized anti-outburst hazard relief drilling construction in the tunneling working face, and realizing the unmanned operation of the roadway hazard relief work.

[0072] For example: In combination with Figures 8 to 13As shown in the figure, the multi-category drilling rig platform includes: a side-mounted self-propelled bolt drill, which includes: a drill body 10, a rotating mechanism, a translation mechanism, and a driving mechanism; the drill body 10 is connected to the translation mechanism through the rotating mechanism, and the drill body 10 can swing under the drive of the rotating mechanism. The translation mechanism is hung on the single-side track 1 of the shield support, and the driving mechanism is used to drive the translation mechanism to slide along the single-side track 1 to drive the drill body 10 to reciprocate. The side-mounted self-propelled bolt drill is installed under the shield support in a side-mounted manner, realizing the horizontal movement and angle adjustment of the drill body 10. This side-mounted self-propelled bolt drill can ensure that the drill body 10 has more adjustment space, and can not only drill and anchor the roadway roof, but also work on both sides of the roadway, avoiding the disadvantages of inconvenient position and angle adjustment of the bolt drill in the traditional process, and realizing the fast and accurate support of the bolt machine in actual construction. It should be noted that, in order to better understand the "side-mounted" method, when the drill body 10 swings under the drive of the rotating mechanism, it can drill on both sides of the roadway; when the drill body 10 does not swing, the angle of its support bolt is perpendicular to the roof.

[0073] In this embodiment, preferably, the translation mechanism includes: a translation slide plate;
