Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to an anchor bolt drilling positioning and angle control device. Background Technology

[0002] Tunnel construction is an engineering project that involves excavating passages underground or in mountains. The construction method must be selected based on geological conditions, taking into account safety, efficiency, and the stability of the surrounding rock. Drill and blast method is a classic method of tunnel construction, which involves drilling, loading explosives, and blasting to break up rocks to form a tunnel, and then gradually advancing the tunnel with the help of support, muck removal, and other processes. It is suitable for hard rock formations.

[0003] To ensure construction and project quality and safety, tunnels constructed using the drill-and-blast method require initial support after excavation. In cases of poor geological conditions, steel arch frames are also used for support. However, due to the construction method, the arch feet of the steel arch frames will be suspended for a period of time during the lower excavation of tunnels supported by steel arch frames. Furthermore, when installing the upper arch frames, they are often placed on loose material, resulting in the load on the unclosed initial support being mainly borne by the anchor bolts.

[0004] The existing method of installing anchor bolts requires drilling holes in the tunnel wall first. During drilling, operators usually use handheld drilling machines. However, when drilling in the upper part of the tunnel, the dust generated falls downwards, affecting the operators' work.

[0005] Therefore, an anchor bolt drilling positioning and angle control device is proposed to address the above problems. Utility Model Content

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5 As shown in the embodiment of this utility model, an anchor bolt drilling positioning and angle control device includes a base 1. A pair of support plates 11 are fixedly connected to the top of the base 1. A dustproof servo motor 12 is fixedly connected to the side wall of the support plate 11. An adjustment platform 13 is fixedly connected to the output end of the dustproof servo motor 12. The adjustment platform 13 is rotatably connected to the support plate 11. A sliding plate 14 is slidably connected to the middle of the adjustment platform 13. A pair of slots 15 are opened at the end of the sliding plate 14. A baffle 16 is provided on the top of the sliding plate 14. The bottom of the baffle 16 is fixedly connected to... There is a pair of insert plates 17; the insert plates 17 and slots 15 are correspondingly arranged and slidably engaged; a pair of fixing bolts 18 are threadedly connected to the side wall of the slide plate 14; the fixing bolts 18 and slots 15 are threadedly connected; an angle gauge 19 is fixedly connected to the inner wall of the support plate 11; the adjustment platform 13 and the angle gauge 19 are slidably connected; during operation, the dustproof servo motor 12 is first started to drive the adjustment platform 13 to rotate. During rotation, the adjustment platform 13 will drive the slide plate 14 to rotate together. At this time, the adjustment platform 13 will be at an angle. The drill bit slides on the ruler 19. During this sliding motion, the angle is compared with the data on the ruler 19 via the adjustment table 13 to observe and adjust the angle. After adjustment, the operator places the drill bit of the drilling machine upwards and then places it on the surface of the slide plate 14. At this time, the drill bit is positioned between a pair of slots 15. After placement, the insert plate 17 is aligned with the slots 15 and inserted to connect the baffle 16 and the slide plate 14. After connection, a pair of fixing bolts 18 are inserted and then rotated into the insert plate 17 to fix the baffle 16. At this time, the drilling machine is started, and the drilling machine is pushed to move the slide plate. 14. Move forward to bring the drill rod closer to the tunnel and drill. During drilling, the flying debris will be blocked by the baffle 16, thus intercepting the debris and reducing contact with the operator. By adding the baffle 16, when the drilling machine is drilling at the top of the tunnel, the debris generated during drilling can be intercepted by the baffle 16 and moved down along the baffle 16, thereby reducing the debris from approaching the operator. At the same time, the baffle 16 can also be removed when drilling in the middle and lower parts, thereby increasing the operator's visibility during drilling.

[0021] like Figures 1 to 4As shown, a pair of foot grooves 2 are provided on the surface of the base 1; a pedal 21 is rotatably connected inside the foot grooves 2; the pedal 21 and the foot grooves 2 are connected by a torsion spring; during operation, when the operator operates the drilling machine, they can place their feet inside the foot grooves 2. When the feet enter the foot grooves 2, they will contact the pedal 21, at which point the feet will push the pedal 21, causing the pedal 21 to rotate, thereby flattening the feet. After the feet leave, the pedal 21 will automatically spring back, and at the same time, the pedal 21 will guide the residual debris between the feet and the pedal 21 to the bottom, thereby cleaning the surface of the pedal 21; by adding foot grooves 2, the operator's feet can be restricted during operation, keeping the feet inside the foot grooves 2, thus improving the operator's positioning. At the same time, after the feet leave, the pedal 21 will automatically spring back, thereby moving the debris on its surface downwards, so that after cleaning, it reaches the bottom of the foot grooves 2 for collection, thus concentrating the debris.

[0022] like Figures 1 to 2 As shown, a cylinder 3 is fixedly connected to the bottom of the adjusting platform 13; a connecting rod 31 is fixedly connected to the output end of the cylinder 3; a push plate 32 is fixedly connected to the end of the connecting rod 31; the push plate 32 and the slide plate 14 are correspondingly arranged; during operation, when the adjusting platform 13 is tilted higher, the force of the drill rising will increase. At this time, the cylinder 3 can be activated to drive the push plate 32 to move through the connecting rod 31. When the push plate 32 moves, it will push the slide plate 14 and the drill to move together. Thus, the push plate 32 increases the assistance when the drill rises, thereby increasing the support for the drill and the slide plate 14 during long-term drilling. By adding the cylinder 3, the impact of resistance can be reduced when the upward resistance is large. At the same time, it can also provide support during long-term operation, thereby increasing the convenience of the operator during drilling.

[0023] like Figures 1 to 5 As shown, a pair of positioning blocks 4 are fixed to the top of the slide plate 14; the positioning blocks 4 are arranged opposite each other in the middle; during operation, when the drill is placed, it can contact the positioning blocks 4, and after contact, the positioning blocks 4 will guide the drill, so that the drill moves towards the middle of the slide plate 14; by adding positioning blocks 4, the adjustment of the drill during placement can be accelerated by the guidance of the positioning blocks 4, thereby speeding up the placement of the drill.

[0024] like Figure 5 As shown, a flexible pad 5 is fixedly connected to the middle of the positioning block 4; the flexible pad 5 and the positioning block 4 are correspondingly arranged; during operation, the vibration generated by the drilling machine will shake inside the positioning block 4, and when it shakes, it will come into contact with the flexible pad 5. At this time, the flexible pad 5 will absorb the impact force through deformation; by adding the flexible pad 5, the impact force can be absorbed by the flexibility of the flexible pad 5 when the drilling machine shakes, thereby increasing the protection of the drilling machine.

[0025] like Figures 2 to 5 As shown, a guide plate 6 is fixed to the side wall of the insert plate 17; the guide plate 6 is inclined on the insert plate 17; during operation, when debris is splashed, the guide plate 6 will intercept the debris diagonally above the baffle 16, causing the debris to move down along the guide plate 6; by adding the guide plate 6, the interception area of ​​the baffle 16 for debris can be increased, thereby increasing the protection of the baffle 16 for the operator.

[0026] Working principle: First, start the dustproof servo motor 12 to drive the adjustment table 13 to rotate. During rotation, the adjustment table 13 will also drive the slide plate 14 to rotate. At this time, the adjustment table 13 will slide on the angle ruler 19. During this sliding, the adjustment table 13 is compared with the data on the angle ruler 19 to observe and adjust the angle. After adjustment, the operator places the drill rod of the drilling machine upwards and then places it on the surface of the slide plate 14. At this time, the drill rod is positioned between a pair of slots 15. After placement, the insertion plate 17 is aligned with the slots 15 and inserted. Connect the baffle 16 and the slide plate 14. After connection, insert a pair of fixing bolts 18 and rotate them into the insert plate 17 to fix the baffle 16. Then start the drilling machine and push it to move the slide plate 14 forward, bringing the drill rod closer to the tunnel. Drilling is then performed. During drilling, flying debris is blocked by the baffle 16, which intercepts the debris and reduces contact with the operator. When the operator operates the drilling machine, they can place their feet inside the foot groove 2. The foot will then contact the pedal 21, at which point the foot will push the pedal 21, causing it to rotate and flatten the foot. After the foot leaves, the pedal 21 will automatically spring back, simultaneously guiding any remaining debris between the foot and the pedal 21 towards the bottom, thus cleaning the surface of the pedal 21. When the adjusting platform 13 is tilted higher, the upward force of the drill increases. At this time, the cylinder 3 can be activated to move the push plate 32 via the connecting rod 31. As the push plate 32 moves, it pushes the slide plate 14 and the drill together, thereby... When the drill rises, the push plate 32 provides additional assistance, thereby increasing support for the drill and slide plate 14 during long-term drilling. When the drill is placed, it can contact the positioning block 4. After contact, the positioning block 4 will guide the drill, causing it to move towards the center of the slide plate 14. When the drill is working, the vibration generated will shake inside the positioning block 4. When shaking, it will contact the flexible pad 5. At this time, the flexible pad 5 will absorb the impact force through deformation. When debris is splashed, the guide plate 6 will intercept the debris diagonally above the baffle 16, causing the debris to move down along the guide plate 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
