Description

Technical Field

[0001] This invention relates to the field of side anchor drilling rig technology, specifically a side anchor drilling rig for roadway support. Background Technology

[0002] Tunnel support is a crucial link in ensuring the safety of underground engineering projects such as underground mining and tunnel construction. As the core equipment in tunnel support construction, the anchor bolt drilling machine is mainly used to drill holes in the tunnel sidewall and install anchor bolts to enhance the stability of the surrounding rock and ensure construction safety and smooth project progress.

[0003] In the current use of side bolt drilling rigs, the drilling position adjustment mostly relies on manual pushing or simple transmission mechanisms. Drilling operations generate a large amount of dust and debris. Existing technologies usually use the method of periodically stopping the machine to manually clean the transmission components to reduce the impact of debris. However, this solution cannot achieve real-time cleaning. Debris easily adheres to the transmission meshing parts, causing transmission jamming and poor meshing, affecting the stability of the machine's movement, and thus leading to work interruption. This reduces the continuity and reliability of support operations. Therefore, a side bolt drilling rig for roadway support is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a side anchor drilling rig for roadway support, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a side anchor drilling rig for roadway support, comprising:

[0006] The column has a sliding shell installed on its exterior. A slide rail is fixedly installed on one side of the exterior of the sliding shell by a frame. Waste discharge grooves are evenly distributed inside the slide rail, and the waste discharge grooves are integrally formed with the slide rail. A support shell is slidably mounted on the upper outer side of the slide rail, and an organism is mounted on the top of the support shell, with the organism and the support shell fixed by bolts. A drive motor is fixedly installed on one side of the lower end of the support shell via a base frame. A drive gear is fixedly installed on the output end of the drive motor. A rack is fixedly installed on the lower end of the slide rail on the side above the drive gear, and the drive gear is meshed with the rack. Side frames are fixedly installed on both sides of the drive motor. A second return spring is installed on the top of the side frame and is fixedly connected to the side frame. A brush is installed on the top of the second return spring and is fixedly connected to the second return spring. The brush is in contact with the rack. The machine body can achieve stable linear movement by driving the meshing transmission of gears and racks through the drive motor, ensuring the accuracy and efficiency of drilling operations. At the same time, the elastic force of the second return spring keeps the brush in contact with the rack and moves synchronously with the drive motor, which can clean the dust and debris on the rack in time, prevent dust and debris from affecting the meshing transmission of gears and racks, ensure smooth movement of the machine body, and improve the continuity and reliability of drilling operations.

[0007] Preferably, the sliding shell is slidably connected to the column, and a side shell is provided on the outer side of the sliding shell opposite to the slide rail, and the side shell is fixedly connected to the sliding shell. The sliding connection allows the sliding shell to move up and down and slide outside the column.

[0008] Preferably, a pull rod is installed inside the side shell, with one end of the pull rod extending to the outside of the side shell. A limiting wedge block is provided at the outside of the pull rod near the column, and the limiting wedge block is fixedly connected to the pull rod. The pull rod facilitates pulling the limiting wedge block, thereby making it easy to pull the limiting wedge block out of the limiting groove and remove the fixation of the sliding shell.

The first return spring enables the limiting wedge block to have automatic reset property.

[0010] Preferably, the outer side of the column near the limiting wedge block has equidistant limiting grooves, and the limiting grooves are integrally formed with the column. The limiting wedge block is adapted to the limiting groove, and the limiting wedge block is inserted into the limiting groove to fix the sliding shell, thereby facilitating fixation after the sliding shell height is adjusted.

[0011] Preferably, handrails are provided on both sides of the upper end of the column, and the handrails are fixedly connected to the column by bolts. A base plate is provided at the bottom of the column, and the base plate is fixedly connected to the column by bolts. The base plate is used to increase the contact area at the bottom of the column and improve the stability of the column.

[0012] Preferably, the lower end of the column is provided with side plates on both the front and rear sides, and the side plates are welded and fixed to the column.

[0013] Preferably, a rotating block is provided on the outside of the side plate, and the rotating block is rotatably connected to the side plate. A support plate is provided on the side of the rotating block that is away from the slide rail, and the rotating block is used to drive the support plate to rotate.

[0015] Preferably, a first limiting hole is provided at the upper end of the inside of the side plate, and a second limiting hole is provided on the side of the inside of the side plate near the slide rail. A limiting bolt is installed inside the rotating block by means of a threaded fit, and the limiting bolt is adapted to the first limiting hole and the second limiting hole respectively. By screwing in and out the limiting bolt, in conjunction with the rotation of the rotating block, the bolt is inserted into the first limiting hole and the second limiting hole respectively to fix the rotating block at the required position.

[0016] Compared with the prior art, the present invention provides a side anchor drilling rig for roadway support, which has the following beneficial effects: This invention utilizes a drive motor to engage a drive gear with a rack, enabling the support shell to move the machine body linearly along a slide rail. This allows the drill bit to move precisely toward the inner wall of the tunnel to complete drilling operations, offering advantages such as convenient drilling position adjustment and high operational efficiency. Simultaneously, a second return spring mounted on the side frame applies a continuous elastic force to the brush, ensuring that the brush moves synchronously with the drive motor and remains in contact with the rack at all times. This allows for timely cleaning of drilling dust and debris from the rack teeth, solving the problem of poor gear and rack meshing and machine body movement jamming caused by dust and debris adhesion. This ensures the stability of the drilling rig's movement and the continuity of operations, improving the reliability of tunnel support drilling operations. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides a technical solution: a side anchor drilling rig for tunnel support. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,include: The column 1 has a sliding shell 2 installed on its exterior. A slide rail 8 is fixedly installed on one side of the exterior of the sliding shell 2 by the support of the frame. Waste discharge grooves 9 are evenly distributed inside the slide rail 8, and the waste discharge grooves 9 are integrally formed with the slide rail 8. A support shell 10 is slidably mounted on the upper outer side of the slide rail 8. An organism 25 is mounted on the top of the support shell 10, and the organism 25 is fixed to the support shell 10 by bolts. A drive motor 11 is fixedly installed on one side of the lower end of the support shell 10 via a base frame. A drive gear 12 is fixedly installed on the output end of the drive motor 11. A rack 13 is fixedly installed on the lower end of the slide rail 8 on one side of the upper end of the drive gear 12, and the drive gear 12 and the rack 13 are meshed and connected. Side frames 14 are fixedly installed on both sides of the drive motor 11. A second return spring 15 is installed on the top of the side frame 14 and is fixedly connected to the side frame 14. A brush 16 is installed on the top of the second return spring 15 and is fixedly connected to the second return spring 15. The brush 16 is in contact with the rack 13. The machine body 25 is started to perform drilling operations. At the same time, the drive motor 11 is started to make the drive gear 12 rotate. Under the meshing action of the drive gear 12 and the rack 13, the rotational motion of the drive gear 12 is converted into the linear sliding motion of the support shell 10, thereby causing the drill bit of the machine body 25 to move towards the inner wall of the tunnel to drill. At the same time, the brush 16 moves with the movement of the drive motor 11. With the reset action of the second return spring 15, the brush 16 is kept in contact with the rack 13 at all times to clean the rack 13 and prevent the dust and debris generated during drilling from adhering to the inside of the teeth of the rack 13 and affecting the movement of the machine body 25. The brush 16 is made of wear-resistant nylon bristles, which are densely arranged and matched with the tooth pattern of the rack 13. The second return spring 15 is a stainless steel compression spring with an elastic coefficient of 2-3 N / mm. Its two ends are fixed to the side frame 14 and the brush 16 by welding to ensure that the pressure of the brush 16 on the rack 13 is stable at 5-8 N, thus ensuring the cleaning effect.

[0021] Please see Figure 2 and Figure 3 The sliding shell 2 is slidably connected to the column 1. A side shell 3 is provided on the side of the sliding shell 2 that is away from the slide rail 8, and the side shell 3 is fixedly connected to the sliding shell 2. The sliding connection allows the sliding shell 2 to move up and down and slide outside the column 1. The inner wall of the sliding housing 2 is fitted with a wear-resistant copper sleeve. The gap between the inner wall of the copper sleeve and the outer wall of the column 1 is controlled at 0.1-0.2mm, and the inner wall of the copper sleeve is coated with lithium-based grease. Dustproof rings are provided at both the upper and lower ends of the sliding housing 2. The dustproof rings fit snugly against the column 1 to prevent dust from entering the sliding gap and affecting the smoothness of lifting.

[0022] Please see Figure 2 and Figure 3 A pull rod 4 is installed inside the side shell 3. One end of the pull rod 4 extends through to the outside of the side shell 3. A limiting wedge block 6 is provided at the outside of the pull rod 4 near the column 1. The limiting wedge block 6 is fixedly connected to the pull rod 4. The pull rod 4 is used to pull the limiting wedge block 6, thereby making it easy to pull the limiting wedge block 6 out of the limiting groove 7 and remove the fixation on the sliding shell 2. The outer end of the pull rod 4 is equipped with a non-slip grip with a non-slip texture on the surface; a guide sleeve is provided at the contact point between the pull rod 4 and the side shell 3. The guide sleeve is made of engineering plastic to ensure accurate linear movement when the pull rod 4 is pulled.

[0023] Please see Figure 2 and Figure 3 The limiting wedge block 6 is slidably connected to the column 1. The limiting wedge block 6 penetrates and extends into the interior of the column 1. The first return spring 5 is installed on the outside of the pull rod 4 on the inside side of the side shell 3. The two ends of the first return spring 5 are fixedly connected to the side shell 3 and the limiting wedge block 6 respectively. The first return spring 5 enables the limiting wedge block 6 to have automatic reset property. The first reset spring 5 is sleeved on the outside of the pull rod 4, and its two ends are fixed to the inner wall of the side shell 3 and the end face of the limiting wedge block 6 respectively through hooks; ensuring that the first reset spring 5 can drive the limiting wedge block 6 to stably embed into the limiting groove 7 in its natural state, and the reset response is rapid.

[0024] Please see Figure 2 and Figure 3 Limiting grooves 7 are provided at equal intervals on the side of the column 1 near the limiting wedge block 6, and the limiting grooves 7 are integrally formed with the column 1. The limiting wedge block 6 is adapted to the limiting groove 7. The limiting wedge block 6 is inserted into the limiting groove 7 to fix the sliding shell 2, so as to facilitate fixing after the height of the sliding shell 2 is adjusted. The adjacent limiting groove 7 is adapted to adjust the height of the sliding shell 2 with precision; the inner wall of the limiting groove 7 is hardened to improve wear resistance and avoid deformation due to long-term insertion and removal.

[0025] Please see Figure 1 and Figure 2Both sides of the upper end of the column 1 are provided with handrails 26, and the handrails 26 are fixedly connected to the column 1 by bolts. The bottom of the column 1 is provided with a base plate 17, and the base plate 17 is fixedly connected to the column 1 by bolts. The base plate 17 is used to increase the contact area at the bottom of the column 1 and improve the stability of the column 1. The handrail frame 26 is made of Φ30mm stainless steel pipe bent into shape, with a rubber anti-slip sleeve on the surface, and is fixed to the flange of the column 1 by M8 bolts; the base 17 is made of 10mm thick steel plate stamped into shape, with a 5mm thick anti-slip rubber pad pasted on the bottom. The dimensions of the base 17 are 400×400mm to ensure sufficient contact area.

[0026] Please see Figure 1 Side plates 18 are provided on both the front and rear sides of the lower end of the column 1, and the side plates 18 are welded and fixed to the column 1. The side plate 18 is cut and formed from an 8mm thick Q355 steel plate, with a size of 200×150mm. The side plate 18 and the column 1 are connected by full welding, with a weld height of 5mm. After welding, it is ground to ensure the connection strength and avoid sharp edges from scratching the operator.

[0027] Please see Figure 1 A rotating block 21 is provided on the outside of the side plate 18, and the rotating block 21 is rotatably connected to the side plate 18. A support plate 23 is provided on the side of the rotating block 21 that is away from the slide rail 8. The rotating block 21 is used to drive the support plate 23 to rotate. The rotating block 21 is connected to the side plate 18 via a Φ20mm stainless steel rotating shaft. Shaft retaining rings are provided at both ends of the rotating shaft for limiting the rotation. Deep groove ball bearings are embedded at the contact points between the rotating shaft and the rotating block 21 and the side plate 18 to reduce rotational resistance and ensure that the rotating block 21 drives the support plate 23 to rotate flexibly without jamming.

[0028] Please see Figure 1 The support plate 23 is fixedly connected to the rotating block 21. A roller 24 is installed on one end of the outer side of the support plate 23, and the roller 24 is rotatably connected to the support plate 23. The roller 24 facilitates the movement of the machine, and the support plate 23 is used to support the machine. The support plate 23 is made of 12mm thick channel steel and is 400mm long. It is fixed to the rotating block 21 by M10 bolts. The roller 24 is a Φ100mm rubber universal wheel with a rated load of 500kg. The roller 24 is connected to the support plate 23 by a pin. The pin is provided with cotter pins at both ends to ensure stable rotation.

[0029] Please see Figure 1The upper part of the side plate 18 is provided with a first limiting hole 19, and the side plate 18 is provided with a second limiting hole 20 on the side near the slide rail 8. The inside of the rotating block 21 is fitted with a limiting bolt 22 by thread engagement, and the limiting bolt 22 is adapted to the first limiting hole 19 and the second limiting hole 20 respectively. By screwing in and out the limiting bolt 22, in conjunction with the rotation of the rotating block 21, it is inserted into the first limiting hole 19 and the second limiting hole 20 respectively to fix the rotating block 21 at the required position. The first limiting hole 19 and the second limiting hole 20 are both M12 threaded holes. The angle between the line connecting the center of the two holes and the center of the rotating shaft is 90°, which is suitable for the vertical and horizontal working positions of the rotating block 21. The limiting bolt 22 is an M12×50mm socket head cap screw with an anti-slip washer on the bolt head to ensure reliable locking after screwing in and to prevent loosening.

[0030] This solution involves unscrewing the limiting bolt 22, then moving the support plate 23 to a position perpendicular to the column 1. At this time, the rotating block 21 rotates accordingly. The limiting bolt 22 is then passed through the rotating block 21 and screwed into the second limiting hole 20 to fix the support plate 23. The column 1 is tilted and the handrail 26 is supported so that the roller 24 contacts the ground of the tunnel. The machine is then moved by the handrail 26 in conjunction with the roller 24. After moving to the position where drilling is required, the column 1 is upright so that the chassis 17 is placed parallel to the ground. The limiting bolt 22 is then unscrewed and the support plate 23 is flipped downwards so that the support plate 23 is parallel to the column 1. The limiting bolt 22 is then screwed into the first limiting hole 19 to fix the rotating block 21. Lift the sliding shell 2, and the sliding shell 2 rises along the column 1. Under the action of the inclined plane and the reset action of the first reset spring 5, the limiting wedge block 6 and the limiting groove 7 repeatedly move out and insert into the limiting groove 7 until they move to the required height. Then, the limiting wedge block 6 and the limiting groove 7 at the corresponding height are engaged to fix the sliding shell 2. When it is necessary to lower the sliding shell 2, pull the pull rod 4 to pull the limiting wedge block 6 out of the limiting groove 7. Then slide down to adjust the position of the sliding shell 2 and release the pull rod 4. The first reset spring 5 resets and pushes the limiting wedge block 6 into the limiting groove 7 to fix the sliding shell 2. The machine body 25 is started to perform drilling operations. At the same time, the drive motor 11 is started to make the drive gear 12 rotate. Under the meshing action of the drive gear 12 and the rack 13, the rotational motion of the drive gear 12 is converted into the linear sliding motion of the support shell 10, thereby causing the drill bit of the machine body 25 to move towards the inner wall of the tunnel to drill. At the same time, the brush 16 moves with the drive motor 11. With the reset action of the second return spring 15, the brush 16 is kept in contact with the rack 13 at all times to clean the rack 13 and prevent the dust and debris generated during drilling from adhering to the inside of the teeth of the rack 13 and affecting the movement of the machine body 25.
