[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0045] See also Figure 1-8 The present invention describes the above technical solution in detail through the following embodiments:

[0046] A drilling and filling device for tunnel construction blasting, such as Figure 1-Figure 3 The structure shown includes a mobile equipment vehicle 1 provided with a vertical guide frame 11, on which a lifting frame 12 is installed for lifting, and further includes:

[0047] The borehole filling part includes an installation chamber 2 installed on the top of the lifting frame 12 through a horizontal support plate 13. A transmission unit 5 is installed in the installation chamber 2 through a power source. A drill rod 3 is rotatably installed on the transmission unit 5. A three-cone drill bit 4 is installed at the top of the drill rod 3. It should be noted that in order to obtain the function of synchronously cleaning slag during drilling, this embodiment has a guide cavity 301 at the axis of the drill rod 3. Water can flow out from the three-cone drill bit 4 through the guide cavity 301, that is, water is injected into the borehole during drilling. With the injection of water, the horizontal hole will bring the slag out of the borehole along with the water flow, and there is no need to clean the borehole separately.

[0048] Specifically, Figure 5-Figure 7As shown in the structure, the installation bin 2 includes a bin body 21 with packaging side panels 23 and limiting side panels 24 detachably installed at both ends, the limiting side panels 24 are provided with insertion holes 241 for inserting the drill rod 3, and the interior of the bin body 21 is provided with symmetrically arranged side embedding cavities 211. In this embodiment, a second hydraulic cylinder 9 serving as a power source is installed in the side embedding cavity 211; and a slide rail 22 is installed at the side embedding cavity 211, and a sliding groove 512 for sliding installation on the slide rail 22 is provided on the support block 51.

[0049] It should be noted that, in this embodiment, the transmission unit 5 is Figure 5 The installation shown in the figure includes a support block 51 provided with a lug 511 connected to the output shaft of the second hydraulic cylinder 9, a pressure block 52 is detachably installed on the support block 51, and a rotation clamping chamber 501 is provided between the support block 51 and the pressure block 52; the main function of the second hydraulic cylinder 9 is to provide a pressure force for drilling inwards and obtain a moving space for retracting the drill rod 3; in order to obtain a stable rotation ability of the drill rod 3, this embodiment is as follows Figure 6 and Figure 7 In the structure shown, a rotating block 54 is installed at the rotating clamp cavity 501, and the rotating block 54 is provided with transmission gears 542 and a cylindrical clamping block 541 for rotating installed in the rotating clamp cavity 501. A first driving motor 53 is installed on the pressing block 52, and a gear meshing with the transmission gear 542 is installed on the output shaft of the first driving motor 53 to provide a rotational driving force.

[0050] It is worth mentioning that a diversion hollow hole 5401 is provided at the axis of the rotating block 54, and a rotating diversion joint 55 and a drill rod 3 are respectively installed at both ends of the diversion hollow hole 5401 on the rotating block 54. A diversion pipe is installed at the other end of the rotating diversion joint 55. The diversion pipe is used to provide water flow for flushing the drill slag material during drilling. The rotating diversion joint 55 can avoid the problem of entanglement of the diversion pipe when the drill rod 3 and the rotating block 54 rotate.

[0051] In order to seal the borehole, taphole mud is generally used as the sealing material, such as Figure 4 In the structure shown, a filling unit 6 corresponding to the position of the drill rod 3 is installed on the installation bin 2, and the filling unit 6 includes a gun mud tube 61 provided with a material chamber 6101. A first hydraulic cylinder 63 is fixedly installed on the outside of the gun mud tube 61, and the material chamber 6101 is used to hold gun mud and fill the drill hole; in this embodiment, a threaded rod 10 is rotatably installed on the installation bin 2 by the second drive motor 7, and a guide slide bar 8 is fixedly installed, the gun mud tube 61 is slidably installed on the guide slide bar 8 and is threadedly connected with the threaded rod 10. When the second drive motor 7 rotates, the filling unit 6 moves along the direction of the threaded rod 10 to adjust the position of the filling unit 6 to avoid obstruction of drilling.

[0052] like Figure 4As shown, a pressure plate 62 connected to the output shaft of the first hydraulic cylinder 63 is provided in the material chamber 6101, and the pressure plate 62 is used to squeeze the cannon mud filled in the material chamber 6101; a sealing pipe cover 611 is installed on the cannon mud pipe 61, and a material extrusion pipe head 612 is provided on the discharge side of the cannon mud pipe 61, and a rubber edge 613 for sealing and fitting on the outer wall of the borehole is provided on the outer side of the material extrusion pipe head 612; Figure 5 In the structure shown, both ends of the extrusion tube head 612 are circular structures, and are gradually contracted from the inside to the outside. When squeezing the gun mud, the gun mud can be squeezed densely through the extrusion tube head 612, and the inner diameter of the outer end of the extrusion tube head 612 is larger than the inner diameter of the borehole, so that the dense gun mud can be fully squeezed in, so that the gun mud and the borehole wall are kept in close contact, thereby completing the filling of the gun mud.
