Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device for anchor cables to prevent collapse on soft rock slopes. Background Technology

[0002] Soft rock formations typically refer to rock layers with low strength, prone to weathering, softening or disintegrating upon contact with water, and often containing numerous joints and fissures. These formations are susceptible to significant deformation under construction loads. Therefore, in soft rock slope protection construction, anchor drilling is prone to problems such as borehole collapse and drill bit jamming. High slope anchors are generally used to reinforce slopes and prevent landslides, so the drilling depth and angle need precise control to ensure the effectiveness of the anchors.

[0003] When using existing drilling equipment, different geological formations encountered during drilling can lead to multiple drill bit changes. For example, a large-diameter drill bit may be used to open the hole, followed by a smaller drill bit to enlarge it. Alternatively, different types of drill bits may be used for different rock formations. Without the internal support of the drill bit, various unexpected situations can easily occur in the unfinished hole. Soft rock is usually low in hardness but may have a high degree of weathering or contain clay minerals, which can easily generate mud during drilling, clogging the drill bit, or causing unstable hole walls that are prone to collapse. After a collapse, secondary drilling and enlargement are required, reducing processing efficiency. Optimization and improvement are needed to address these issues. Utility Model Content

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] like Figure 1 - Figure 4 As shown, this application provides a drilling device for anchor cables used for preventing collapse on soft rock slopes, including: a support base 1, a slide rail 2 fixedly installed at the top of the support base 1, an adjusting mounting base 3 slidably connected to the top of the slide rail 2, and a motor 4 installed at the top of the adjusting mounting base 3; a drilling adjustment assembly including a drill rod 6, the drill rod 6 being installed on one side of the adjusting mounting base 3, a drill bit 7 connected to one end of the drill rod 6, and a slag discharge groove 8 provided on the outer side of the drill rod 6, and a telescopic blade 12 connected to the inner side of the drill bit 7; the drilling adjustment assembly is used to adjust the drilling mode; specifically, as shown... Figure 1 As shown, mounting plates 5 are fixedly connected to both outer ends of the support base 1. A fitting cover 9 is fixedly installed on one side of the support base 1. The fitting cover 9 is used for protection when dust is discharged. Mounting blocks are set on both sides of the top of the mounting plate 5 for the installation of air pumps and liquid pumps. The pump hoses are connected to the air inlet fitting pipe 19 and the liquid inlet fitting pipe 20.

[0022] Specifically, such as Figure 3 As shown, a rotating rod 11 is fixedly connected inside the drill bit 7, and a telescopic blade 12 is rotatably connected to the outside of the rotating rod 11. The telescopic blade 12 is rotatably connected to the outside of the rotating rod 11 through two connecting plates, one above and one below.

[0023] Specifically, both sides of the outer wall of the drill bit 7 are provided with a storage groove 10 that is slidably connected to the telescopic wing 12. When the telescopic wing 12 is squeezed, it can extend outward through the storage groove 10 to realize one-time hole enlargement to the anchor rod installation diameter, reducing the secondary hole enlargement process.

[0024] Specifically, a V-shaped spring 13 is fixedly connected to the inner side of the telescopic wing 12. The V-shaped spring 13 is used to reset the telescopic wing 12 when it loses external pressure. One end of the telescopic wing 12 is connected to a hydraulic telescopic head 14. Under the action of an external hydraulic mechanism, the end of the hydraulic telescopic head 14 is driven to push into the inner side of the telescopic wing 12 to expand the telescopic wing 12.

[0025] The borehole wall stabilization assembly includes a rotating connecting seat 15 and an injection groove 17. The rotating connecting seat 15 is rotatably connected to one rotating end of the motor 4, and the injection groove 17 is located on the inner side of the drill rod 6. The borehole wall stabilization assembly is used for stabilization after drilling.

[0026] Specifically, such as Figure 4 As shown, the inner side of the rotating connecting seat 15 is provided with an arc-shaped groove 16. The arc-shaped groove 16 has the same diameter as the inlet fitting pipe 19 and the liquid fitting pipe 20. It fits into the inner side of the inlet fitting pipe 19 and the liquid fitting pipe 20 for the transmission of gas and materials. The outer wall of the drill rod 6 is provided with a diversion hole 18 that penetrates the injection tank 17. The gas and materials are transmitted into the injection tank 17 and then dispersed and regulated through the diversion hole 18.

[0027] Specifically, an air inlet fitting pipe 19 is installed on one end of the outer wall of the adjusting mounting base 3 and the outer end of the rotating connecting base 15. Compressed air is injected through the air inlet fitting pipe 19, so that soft rock fragments are discharged out of the hole in real time along the ash discharge chute 8, avoiding the efficiency reduction caused by repeated crushing.

[0028] Specifically, a liquid inlet fitting pipe 20 is installed on one side of the outer wall of the adjusting mounting base 3, which is attached to the outer side of the rotating connecting base 15. Reinforcing materials such as resin or nano silicate are injected through the liquid inlet fitting pipe 20 and flow out from the injection tank 17 and the diversion hole 18. During drilling, the material is released to the hole wall simultaneously and forms a protective wall layer after solidification to prevent hole collapse.

[0029] In this embodiment: a dust discharge groove 8 is provided on the outside of the drill rod 6 to facilitate the removal of dust and chips. Then, a rotatable and adjustable telescopic wing 12 is provided inside the drill bit 7 at the end. After drilling through the end of the drill bit 7, the telescopic wing 12 is unfolded by the hydraulic telescopic head 14 to adjust the hole size, so as to achieve one-time hole enlargement to the installation diameter of the anchor rod, reducing the secondary hole enlargement process and avoiding the collapse of the hole when the drill bit 7 is replaced and adjusted. During drilling, an air inlet fitting pipe 19 and a liquid inlet fitting pipe 20 are provided to deliver compressed air and reinforcing material to the inside of the drill rod 6. The injection of air facilitates the discharge of debris, and the injection of reinforcing material forms a protective wall layer after solidification to prevent hole collapse.

[0030] The specific steps of this solution are as follows: When drilling on a soft rock slope, first, the support base 1 is fixedly installed. Then, the drilling position of the drill bit 7 is adjusted so that the fitting cover 9 is attached to the slope. Then, the motor 4 drives the rotating connecting seat 15, the drill rod 6, and the drill bit 7 to rotate and adjust. A dust discharge groove 8 is set on the outside of the drill rod 6 to facilitate the removal of dust and chips. During drilling, an air inlet fitting pipe 19 and a liquid inlet fitting pipe 20 are attached to the arc-shaped groove 16 on the outside of the rotating connecting seat 15. Compressed air and reinforcing material are delivered to the inside of the drill rod 6 through the injection groove 17. The injection of air can remove internal debris. The material is blown out and discharged through the ash discharge trough 8. After the reinforcing material is injected and cured, it forms a protective wall layer to prevent hole collapse. Then, the drill bit 7 at the end is equipped with a rotatable and adjustable telescopic wing 12. After drilling through the end of the drill bit 7, the telescopic wing 12 is unfolded by the hydraulic telescopic head 14. At this time, the V-shaped spring 13 deforms and extends the telescopic wing 12 out of the receiving groove 10 for hole enlargement adjustment. This achieves one-time hole enlargement to the anchor bolt installation diameter, reduces the secondary hole enlargement process, avoids hole collapse when the drill bit 7 is replaced and adjusted, improves the stability of the drilling, and ensures the subsequent use efficiency of the hole.
