In some embodiments, the hydraulic system 109 provides power to the tunneling machine 1 and the roof-bolter. This arrangement can improve the stability and reliability of the six-arm tunneling and anchoring machine for integrating tunneling and anchoring.

According to the present disclosure, some embodiments of the present disclosure provide a six-arm tunneling and anchoring machine for integrating tunneling and anchoring, which solves the problems of time waste caused by the separate work of the tunneling machine and the roof-bolter as well as the high labor intensity and low efficiency of manually drilling and installing bolts are solved, and realizes the integrated effect of the tunneling machine and the roof-bolter. This machine replaces the manual drilling and bolt installation with a single bolt drilling and installing machine in the present comprehensive excavation of coal, reduces the unsupported roof and side bolting time, meets a support requirement for tunneling in the unsupported roof area, guarantees the safety of workers, and improves the degree of mechanical automation. There is no need to move the whole tunneling and anchoring machine when installing the roof bolt and the side bolt, and the purpose can be achieved just by adjusting the positions of the top anchor bolt and the side bolt driller, so the operation is simple, the efficiency of tunneling and support in tunnels is improved, and the service life of the tunneling and anchoring machine is prolonged.

The working platform group is arranged above the cutting part to provide a working space for the workers during the bolt construction. When the tunneling and anchoring machine is tunneling and cutting, the roof-bolter retracts and folds to reduce the space size of the roof-bolter to the greatest extent. After the completion of the cutting operation of the tunneling and anchoring machine, there is no need to move the whole machine, and it is only needed to expand, rotate and swing the roof-bolter to unfold it, and then it reaches the front-end operation position to perform a bolt support operation, thus significantly improving the working efficiency of tunneling and support in the tunnel.

According to the second embodiment of the disclosure, the six-arm tunneling and anchoring machine for integrating tunneling and anchoring includes a tunneling machine 1, a roof bolt unit 2, a side bolt unit 3 and a working platform group 4. The tunnel machine 1 includes a frame body 101, a walking part 102, a cutting part 103, a revolving body 104, a rear support body 105, a loading mechanism 106, a conveyor 107, an electronic control system 108, a hydraulic system 109, a spraying system 110, and a cooling system 111. The tunneling machine 1, the roof bolt unit 2, the side bolt unit 3 and the working platform group 4 share one hydraulic system 109. There are two roof bolt units 2 which are symmetrically arranged at two sides of the frame body 101 and behind the revolving center of the revolving body 104. The side bolt unit 3 is arranged in the middle of the upper part of the frame body 101 and behind the cutting part 103. The working platform group 4 is mounted on the upper part of the cutting part 103.

There are two roof bolt units 2 which are symmetrical and have the same structure type. Now, only one of the two roof bolt unit is illustrated in the accompanying drawings. As shown in FIG. 3, FIG. 4 and FIG. 5, the roof bolt unit 2 mainly includes the primary retractable sleeve 201, the secondary retractable sleeve 212, the primary retractable oil cylinder 202, the secondary retractable oil cylinder 203, the first rotating oil cylinder 211, the rotating base 213, the top anchor bolts (204, 209), the first oil cylinders swinging back and forth (207, 216), the oil cylinders swinging from side to side (217, 218), the driller mounting bases (205, 208), and the support oil cylinder 206. The primary retractable sleeve 201 is driven by the primary retractable oil cylinder 202 to slide back and forth along the fixed guide rail 219. After the primary retractable sleeve 201 slides forward for a distance to reach the upper part of the support roller 210, the support roller 210 plays a guiding and supporting role to prevent the problem that the rigidity gets weaker caused by over-long cantilever after the primary retractable sleeve 201 and the secondary retractable sleeve 212 slide forward. Both the fixed guide rail 219 and the support roller 210 are mounted on the walking part 102 respectively. When a construction operation of roof bolt is required, the primary retractable sleeve 201 and the secondary retractable sleeve 212 slide forward respectively under the drive of the primary retractable oil cylinder 202 and the secondary retractable oil cylinder 203 to reach the operating position, and under the drive of the first rotating oil cylinder 211, the top anchor bolts (204, 209) rotate 90° inwards with the rotating base 213, then the support oil cylinder 206 extends out and effectively supports the base board. In this way, the stability of the whole roof bolt unit 2 of the top anchor bolts (204, 209) during drilling can be greatly improved. The top anchor bolts (204, 209) are respectively mounted on the rotating base 213 through the rig driller mounting bases (208, 205). Under the drive of the first oil cylinders swinging back and forth (207, 216), the driller mounting bases (208, 205) enable the top anchor bolts (204, 209) to swing back and forth independently. The top anchor bolts (204, 209) can swing from side to side independently under the drive of the oil cylinders swinging from side to side (217, 218). The swing back and forth and the swing from side to side of the top anchor bolts (204, 209) makes it easy and fast to locate the drilling position, thus improving the working efficiency. When a construction operation of roof bolt is carried out, the four top anchor bolts (204, 209, 214, 215) of the left and right top anchor bolt units 2 are lined up, and can carry out a roof bolt and anchor cable operation at the same time, thus greatly improving the work efficiency.

When a construction operation of side bolt is carried, the retractable inner sleeve 304 extends forward under the drive of the retractable oil cylinder 303 to reach the operating position. The side bolt drillers (306, 308) respectively rotate 90° outward under the drive of the second rotating oil cylinders (305, 309), then the drilling position is found exactly through the coordination between the back-and-forth retractable motion of the retractable inner sleeve 304 and the up-and-down lifting of the lifting oil cylinder 307, at the same time, two rows of bolt support at the upper end of the two sides are carried out, so the working efficiency is high. The portal support 301 straddles the upper rear end of the conveyor 107, and is mounted on the rear support body 105. This arrangement increases the length of the retractable outer sleeve 302 and the retractable inner sleeve 304, and then improve a retracting stroke. Under extreme conditions, the side bolt drillers (306, 308) are retracted to the tunneling position to carry out two rows of bolt support at the upper end of the two sides.

As shown in FIG. 7 and FIG. 8, the working platform group 4 mainly includes the large platform 404, the turning plates (405, 409), the retractable turning plates (406, 410), the connecting rod 402, the leveling oil cylinder 403, the second oil cylinder swinging back and forth 401, the turning plate oil cylinders (408, 411), and the retractable turning plate oil cylinders (407, 412). There are two leveling oil cylinders 403, which are arranged at two sides of the cutting part 103. The connecting rod 402 and one of the leveling oil cylinders 403 are arranged at the same side of the cutting part 103, while the other leveling oil cylinder 403 and the second oil cylinder swinging back and forth 401 are arranged at the other side of the cutting part 103. One end of the leveling oil cylinder 103 and one end of the connecting rod 402 are respectively hinged on the cutting part 103, and the other ends are hinged on the large platform. Four hinged points form a quadrilateral mechanism. The mechanism has simple structure and large forth and back swing amplitude, can adjust the height of the large platform 404, and realize, under the drive of the second oil cylinder swinging back and forth 401, the transition from the retracted state to the operating state of the working platform group 4. The turning plates (405, 409) rotate 90° outwards under the drive of the turning plate oil cylinders (408, 411), and the retractable turning plates (406, 410) extend and retract toward both sides under the drive of the retractable turning plate oil cylinders (407, 412). The large platform 404, the turning plates (405, 409) and the retractable turning plates (406, 410) constitute a large working platform, and the leveling oil cylinder 403 can adjust the large platform 404 at a horizontal position in real time according to the change of the upper and lower positions of the cutting part 103, thus greatly increasing the working range of the operators and improving the safety and comfort of the operators. In FIG. 10, A is roof bolt, B is anchor cable support, which can be constructed by the top anchor bolt or supplemented behind the side as required on site, C is the lower two rows of side bolts supplemented behind the side, and D is the upper two rows of side bolts.
