[0041] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Each example is provided by way of explanation of the present application rather than limiting the present application. In fact, those skilled in the art will appreciate that modifications and variations can be made to the present application without departing from the scope or spirit thereof. For example, features shown or described as part of one embodiment can be used in another embodiment to yield yet another embodiment. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the embodiments of the present invention shall fall within the scope of protection of the embodiments of the present invention.

[0042] During the installation and construction process of the bolt for supporting underground mine roadways, due to the installation and disassembly of the drill pipe, the position of the drill rig changes, resulting in the bolt not being accurately located on the center line of the drill hole when inserted into the drill hole. This causes friction between the bolt and the drill hole wall during stirring, resulting in the rotational speed of the drill pipe not reaching the rotational speed required for sufficient mixing of the resin anchoring agent. As a result, the resin anchoring agent cannot be fully stirred and effectively cured, affecting the anchoring effect of the bolt and failing to achieve the effect of bolt support for controlling the deformation of the surrounding rock.

[0043] Based on this, an embodiment of the present application provides a bolt anchoring device, which is installed in the expanded hole at the orifice of the bolt drill hole and is detachably connected coaxially with the working bolt in the bolt drill hole. It can not only transmit the pushing force along the axial direction of the bolt drill hole to push the resin anchoring agent to the bottom of the bolt drill hole, but also transmit the rotational power along the circumferential direction of the bolt drill hole to drive the working bolt to rotate and stir the resin anchoring agent. During the stirring process, the working bolt is always located at the center of the bolt drill hole through the anchoring device, effectively avoiding friction with the coal (rock) hole wall and reducing the rotational speed, enabling the resin anchoring agent to be fully stirred and effectively cured, and enhancing the anchoring effect.

[0044] As Figures 1 to 9As shown, the bolt anchoring device 500 includes a clamping sleeve 502, a power transmission sleeve 503 and a guiding and fixing seat 504 which are coaxially arranged. Among them, the clamping sleeve 502 circumferentially wraps and radially clamps the working bolt 400. The tubular power transmission sleeve 503 is installed on the outer side wall of the clamping sleeve 502 and cooperates with the clamping sleeve 502 to axially transmit the pushing force along the bolt hole 100. The guiding and fixing seat 504 is sleeved in the expansion hole 200 and can axially move along the bolt hole 100 together with the power transmission sleeve 503 in the expansion hole 200, so as to push the resin anchoring agent 300 located between the end of the working bolt 400 and the bottom of the bolt hole 100 to the bottom of the bolt hole 100 by the pushing force. At the same time, after the resin anchoring agent 300 is pushed to the bottom of the bolt hole 100, the guiding and fixing seat 504 is axially fixed to the orifice end face of the bolt hole 100, and the guiding and fixing seat 504 is rotatably connected with the power transmission sleeve 503. The power transmission sleeve 503 and the clamping sleeve 502 cooperate with each other to circumferentially transmit the rotational power along the clamping sleeve 502 and drive the working bolt 400 to rotate through the rotational power to stir the resin anchoring agent 300.

[0045] In this application, the clamping sleeve 502 adopts a split structure with butt joints. During the connection with the working bolt 400, after the two split units of the clamping sleeve 502 are butted on the outer side wall of the working bolt 400 from the outside of the working bolt 400, the assembled power transmission sleeve 503 and guiding and fixing seat 504 are axially pushed along the bolt hole 100, and the power transmission sleeve 503 squeezes the two split units of the clamping sleeve 502, so that the split structure circumferentially wraps and radially clamps the working bolt 400. Among them, through the radially adjustable groove 522 axially arranged on the clamping sleeve 502, it is not only convenient for the installation of the two split units of the clamping sleeve 502, but also can adapt to a wider range of sizes of the working bolt 400.

[0046] In order to avoid damage to the outer side wall of the working bolt 400, a bushing 501 is further arranged between the clamping sleeve 502 and the working bolt 400, and thus the outer side wall of the working bolt 400 can be protected through the bushing 501. At the same time, the material hardness of the clamping sleeve 502 is less than that of the working bolt 400 to further avoid frictional damage to the surface of the working bolt 400 and improve the service life of the working bolt 400.

[0047] In this application, the propelling force is transmitted through the axially mating power transmission parts 532 provided on the clamping sleeve 502 and the power transmission sleeve 503, and the resin anchoring agent 300 located between the end of the working anchor bolt 400 and the bottom of the anchor bolt borehole 100 is pushed to the bottom of the anchor bolt borehole 100. In a specific example, the axially power transmission part 532 is located at the ends of the clamping sleeve 502 and the power transmission sleeve 503. For example, radially extending power transmission ear plates are respectively provided at the ends (both ends are acceptable) of the clamping sleeve 502 and the power transmission sleeve 503, and the axial propelling force is transmitted through the mutual abutment of the power transmission ear plates; alternatively, a power transmission ear plate is provided at one end of the clamping sleeve 502 away from the orifice of the anchor bolt borehole 100, and one end of the power transmission sleeve 503 away from the orifice of the anchor bolt borehole 100 abuts against the end face of the power transmission ear plate of the clamping sleeve 502 to transmit the axial propelling force; alternatively, a power transmission ear plate extending radially inwards is provided at one end of the power transmission sleeve 503 close to the orifice of the anchor bolt borehole 100, and the power transmission ear plate of the power transmission sleeve 503 abuts against one end of the clamping sleeve 502 close to the orifice of the anchor bolt borehole 100 to transmit the axial propelling force.

[0048] In this application, the power transmission sleeve 503 and the clamping sleeve 502 cooperate with each other to transmit the rotational power along the circumferential direction of the clamping sleeve 502, and drive the working anchor bolt 400 to rotate through the rotational power to stir the resin anchoring agent 300. Specifically, a plurality of power sliding grooves 512 are provided on the outer side wall of the clamping sleeve 502, the plurality of power sliding grooves 512 are evenly distributed along the circumferential direction of the clamping sleeve 502, and the power sliding grooves 512 extend along the axial direction of the clamping sleeve 502; correspondingly, power sliding rails 523 adapted to the power sliding grooves 512 are provided on the inner side wall of the power transmission sleeve 503, and the power sliding rails 523 are slidably inserted into the power sliding grooves 512 to transmit the rotational power and drive the working anchor bolt 400 to rotate.

[0049] Here, the transmission of rotational power is achieved through the cooperation of multiple power sliding grooves 512 and multiple power sliding rails 523. At the same time, the transmission of axial thrust can also be achieved through the cooperation of the end faces of the power sliding groove 512 and the power sliding rail 523. That is to say, the cooperation of the end faces of the power sliding groove 512 and the power sliding rail 523 serves as the axially matching power transmission part 532 provided on the clamping sleeve 502 and the power transmission sleeve 503 to achieve the transmission of axial thrust, so as to further simplify the structures of the clamping sleeve 502 and the power transmission sleeve. Specifically, both the clamping sleeve 502 and the power transmission sleeve 503 adopt a cylindrical structure. A power sliding groove 512 that extends axially but does not penetrate is provided on the outer side wall of the clamping sleeve 502, and a corresponding power sliding rail 523 is provided on the inner side wall of the power transmission sleeve 503, so that the end face of the power sliding rail 523 abuts against the end face of the power sliding groove 512 to transmit the axial thrust between the clamping sleeve 502 and the power transmission sleeve 503.

[0050] In the embodiment of the present application, the resin anchor 300 is pushed to the bottom of the bolt hole 100 through the axial thrust. Among them, a matching positioning power part is provided between the guiding and fixing seat 504 and the power transmission sleeve 503, so that the guiding and fixing seat 504 and the power transmission sleeve 503 move axially along the bolt hole 100 together. Specifically, a first positioning power boss 513 that extends radially inward is provided on the inner side wall of the guiding and fixing seat 504. Correspondingly, a second positioning power boss 514 that extends radially outward is provided on the outer side wall of the power transmission sleeve 503. Among them, annular clamping grooves are provided on the first positioning power boss 513 and the second positioning power boss 514, and balls 506 are provided in the annular clamping grooves, so that the axial thrust is transmitted between the guiding and fixing seat 504 and the power transmission sleeve 503 through the balls 506 provided in the annular clamping grooves. Here, it should be noted that the balls 506 can also be replaced by thrust bearings to achieve the transmission of axial thrust between the guiding and fixing seat 504 and the power transmission sleeve 503.

[0051] After the resin anchor 300 is pushed to the bottom of the bolt hole 100, the guiding and fixing seat 504 is axially fixed to the orifice end face of the bolt hole 100, so that the power transmission sleeve 503 can rotate relative to the guiding and fixing seat 504 to achieve the transmission of rotational power. Specifically, the guiding and fixing seat 504 adopts a cylindrical structure, and a fixing plate that extends radially is provided at one end close to the orifice of the bolt hole 100. A fixing through hole is opened on the fixing plate, and the fixing plate is abutted against the orifice end face of the bolt hole 100 (the orifice end face of the expansion hole 200) through a fastening bolt or other fasteners to fix the guiding and fixing seat 504 in the expansion hole 200.

[0052] Meanwhile, the guiding fixed seat 504 is rotatably connected to the power transmission sleeve 503. Specifically, both ends of the guiding fixed seat 504 and the power transmission sleeve 503 are respectively connected by rotating bearings 505, and the outer end faces of the rotating bearings 505 are sealed by mating bearing covers. Further, through the coordinated cooperation of the guiding fixed seat 504, the power transmission sleeve 503 and the clamping sleeve 502, rotational power is transmitted circumferentially along the clamping sleeve 502, and the working bolt 400 is driven to rotate by the rotational power to stir the resin anchor 300.

[0053] During the construction process using the bolt anchoring device 500 of any of the above embodiments, first, the orifice of the bolt hole 100 that has been constructed is reamed to obtain an expanded hole 200 adapted to the anchoring device. Secondly, after the resin anchor 300 is placed in the bolt hole 100, the bolt anchoring device 500 is installed on the working bolt 400, and a pushing force is applied to the bolt anchoring device 500 along the axial direction of the bolt hole 100 to send the bolt anchoring device 500 into the expanded hole 200 and push the resin anchor 300 located between the end of the working bolt 400 and the bottom of the bolt hole 100 to the bottom of the bolt hole 100; then, after the guiding fixed seat 504 in the bolt anchoring device 500 is axially fixed to the orifice end face of the bolt hole 100, the working bolt 400 is connected to the bolt drill to transmit the rotational power of the bolt drill to the working bolt 400 to stir the resin anchor 300. Finally, after the resin anchor 300 is stirred and cured, the bolt drill and the bolt anchoring device 500 are removed, and accessories such as trays, gaskets, nuts required for bolt anchoring are installed, and a pre-tightening force is applied to the working bolt 400 in the bolt hole 100.
