[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model aims to provide an anchor drilling device carried by a tunnel boring machine, so as to solve the technical problems of low efficiency, poor safety and poor supporting effect of manual support in existing tunnel excavation.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figures 1 to 6 As shown, this embodiment provides an anchor drilling device mounted on a roadheader, comprising an inner drill frame sliding support frame 7, an outer drill frame swing support frame 5, a rocker mechanism 3, an inner drill frame 2, and an outer drill frame 4. The bottom of the inner drill frame sliding support frame 7 is connected to the roadheader. The inner drill frame 2 is mounted on one side of the inner drill frame sliding support frame 7, and the other side of the inner drill frame sliding support frame 7 is connected to one end of the rocker mechanism 3. The other end of the rocker mechanism 3 is connected to one side of the outer drill frame swing support frame 5, and the outer drill frame 4 is mounted on the other side of the outer drill frame swing support frame 5. Laser pointers 9 are also provided on the inner drill frame 2 and the outer drill frame 4.

[0031] The height of the outer drill frame 4 is adjusted by the rocker mechanism 3, and the angle of the outer drill frame 4 is adjusted by rotating the outer drill frame swing support frame 5 to meet different anchoring requirements. Compared with manual support, this not only improves underground construction safety, but also increases excavation speed and efficiency, reduces labor costs, and improves support effectiveness. The laser pointer 9 can guide the anchor target point, improving the accuracy of the anchor drill.

[0032] In this specific embodiment, the rocker mechanism 3 includes a telescopic beam and a rocker cylinder 6. One end of the fixed end of the telescopic beam is hinged to the middle of the other side of the inner drill rig sliding support frame 7, and the end of the movable end of the telescopic beam is hinged to the outer drill rig swing support frame 5. One end of the rocker cylinder 6 is hinged to the lower portion of the inner drill rig sliding support frame 7, and the other end of the rocker cylinder 6 is hinged to the other end of the fixed end of the telescopic beam. In a more specific embodiment, two rocker cylinders 6 are positioned between the telescopic beam and the inner drill rig 2 sliding support. One end of each rocker cylinder 6 is connected to either side of the lower portion of the inner drill rig sliding support frame 7, and the other end of each rocker cylinder 6 is hinged to the other end of the fixed end of the telescopic beam. The telescopic beam is a telescopic cylinder. The extension and retraction of the rocker cylinder 6 allows for adjustment of the drilling and anchoring range, thus increasing its applicability. The extension and retraction of the rocker cylinder 6 ensures stable rotation of the telescopic beam and secures it once fully rotated.

[0033] The outer drill frame 4 and the outer drill frame swing support frame 5 are hinged.

[0034] A slide rail 1 is provided between the inner drill frame sliding support frame 7 and the roadheader. The slide rail 1 is fixedly connected to the roadheader, and the inner drill frame sliding support frame 7 is slidably arranged on the slide rail 1. The slide rail 1 is used to mount the inner drill frame sliding support frame 7 on the roadheader, thereby enabling the entire roadheader-mounted anchor drilling device to be installed on the roadheader, thereby facilitating the support and anchoring of the newly excavated tunnel.

[0035] The slide rail 1, the outer drill frame swing support frame 5, the outer drill frame swing support frame 5 and the inner drill frame sliding support frame 7 are all hollow structures.

[0036] The laser pointer bracket 8 installed on the outer drill frame 4 and the inner drill frame 2 can point and guide the anchor target point through the laser pointer 9 installed thereon, thereby improving the accuracy of the anchor drill. Compared with manual support, it not only improves the safety of underground construction, but also improves the excavation speed and efficiency, reduces labor costs, and improves the support effect.

[0037] The laser pointer adjustment bracket 8 includes a bracket fixing device 12, an adjustment device 11, a pointer fixing device 10 and a pointer power fixing device 13. The bracket fixing device 12 is connected to one side of the outer drill frame 4 or the inner drill frame 2 by a thread. The adjustment device 11 is fan-shaped, and its arc center end is connected to the upper end of the outer side of the bracket fixing device 12 by a swivel pin. It can rotate at a certain angle to adjust its angle, and the side thread of the bracket fixing device 12 is used to adjust its tightness. The laser pointer 9 is fixed to the pointer fixing device 10 by a thread, and the laser pointer power supply is placed in the pointer power fixing device 13.

[0038] The arc center angle of the adjustment device 11 in the laser pointing instrument adjustment bracket 8 is 45°.

[0039] When anchor support is required for a newly excavated tunnel, the working process of the anchor drill device on the roadheader in this embodiment is as follows:

[0040] Before commencing operation, calibrate the laser pointer 9 by adjusting the adjustment device 11 of the laser pointer adjustment bracket 8. After calibration, secure the adjustment device 11 with the screw thread. The swing of the rocker mechanism 3 is controlled by the rocker cylinder 6. By adjusting the rocker cylinder 6, the movable rod of the rocker mechanism 3 is rotated to the appropriate position, thereby determining the height of the external drilling rig 4. The angle of the external drilling rig 4 is determined by the front telescopic beam along the length of the rocker mechanism 3 and the external drilling rig swing support frame 5 on which the external drilling rig 4 is located. By adjusting the rocker mechanism 3 and the swing support frame 4 simultaneously, the external drilling rig 4 can be supported to the appropriate working height and angle.

[0041] During anchoring work, if drilling and anchoring operations need to be performed at a distance from the fuselage, the second telescopic cylinder of the front telescopic beam in the longitudinal direction of the front sway link mechanism 3 can be controlled to extend the front telescopic beam forward, thereby increasing the distance of the outer drilling frame 4 and achieving efficient anchoring operations.

[0042] When the tunnel top surface is not horizontal but inclined, since the external drilling rig swing support frame 5 is hinged with the rocker mechanism 3 and the rocker cylinder 6, the rocker cylinder 6 can be adjusted separately to control the external drilling rig 4 to the required angle and then stop adjusting, thereby achieving anchoring of tunnel top surfaces at different angles.

[0043] When the anchoring support is completed, in order not to affect the continued excavation of the tunnel boring machine, the tunnel boring machine's onboard anchor drilling device can be retracted: control the second telescopic cylinder to retract the front telescopic beam, control the rocker cylinder 6 to lower the rocker mechanism 3 to the lowest position, and control the front telescopic beam of the rocker mechanism 3 in the length direction to retract until the laser line of the laser pointer 9 carried on the external drilling rig 4 is parallel, and then turn off the hydraulic system of the tunnel boring machine's onboard anchor drilling device, wait for the tunnel boring machine to continue excavation work, and carry out the next cycle support operation.

[0044] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description.
