Description

Technical Field

[0001] This invention belongs to the technical field of drilling rig support devices, specifically relating to an angle adjustment frame for a smooth blasting drilling machine. Background Technology

[0002] The main construction methods for roadbed rock excavation are mechanical excavation and blasting. Blasting on-site is mostly carried out using controlled blasting and smooth blasting, which effectively reduces the safety risks of blasting construction. Smooth blasting can effectively avoid or weaken the destructive effect on the surrounding rock during rock excavation and blasting, increase slope stability, and thus control and reduce the probability of landslides and other disasters caused by slope failure.

[0003] When using smooth blasting to excavate slopes, blast holes are arranged at appropriate intervals around the excavation boundary. With a lateral free face, blasting is performed by controlling the resistance line and the amount of explosives to create a smooth and flat slope. However, in actual construction, the blast holes drilled on the slope are prone to deviation, causing changes in the resistance line and affecting the effectiveness of smooth blasting. Therefore, a drilling platform for installing the drilling rig is needed on the slope to stabilize the drilling. Existing drilling platforms typically require ground anchors or workers to press down on them to secure them. However, using ground anchors is inconvenient for installation and removal, resulting in low drilling efficiency and extended construction time; while workers pressing down on the platform leads to instability. Therefore, a drilling platform that is easily fixed to the slope needs to be designed. Summary of the Invention

[0004] The present invention aims to provide an angle adjustment frame for a smooth blasting drilling machine to solve the problem of inconvenience in disassembling and assembling existing drilling platforms on slopes.

[0005] To achieve the above objectives, the present invention provides an angle adjustment frame for a smooth blasting drilling machine, comprising a drilling machine mounting base and a support frame for supporting the drilling machine mounting base. The support frame includes a base, a support column, and a crossbeam. Lateral support plates are mounted on both sides of the drilling machine mounting base. A rotating shaft is fixedly connected to the lateral support plates and rotatably connected to the crossbeam. A first angle scale is coaxially mounted on the rotating shaft. A locking element for fixing the first angle scale is provided on the rotating shaft. A first pointer for indicating the first angle scale is provided on the rotating shaft. The crossbeam is equipped with a second pointer for indicating the first angle scale. Both the first and second pointers are horizontally positioned and point to the 90° mark on the first angle scale. The crossbeam is equipped with a telescopic assembly, a first locking assembly for fixing the first angle scale, and a second locking assembly for fixing the rotating shaft. The telescopic assembly includes a ring with a steel wire rope passing through it. The two ends of the steel wire rope are fixed to the top and bottom of the slope, respectively. A cylinder for the steel wire rope to pass through is fixedly connected to the crossbeam or support column.

[0006] The working principle and beneficial effects of this solution are as follows:

[0007] 1. In this scheme, the two ends of the wire rope are fixed to the top and bottom of the slope, respectively, and the wire rope passes through the cylinder and the ring. Therefore, the distance between the ring and the slope can be adjusted by the telescopic component, thereby adjusting the tension of the wire rope and the pressure exerted by the wire rope on the support frame. This ensures that the support frame is stably fixed on the slope, avoiding the use of ground anchors to fix the support frame. It is also convenient to assemble and disassemble, improving construction efficiency.

[0008] 2. In this solution, the first angle dial rotates with the rotating shaft. Thus, when the support frame is installed on the slope, rotating the rotating shaft ensures that the sum of the slope inclination angle and the angle indicated by the second pointer equals 90°, thus ensuring that the drilling angle is 90° as indicated by the first pointer. Subsequently, under the action of the first locking component, the first angle dial remains stationary during the rotation of the rotating shaft. Afterward, rotating the drilling machine mounting base will reveal the drilling angle indicated by the first pointer. The second locking component is then used to fix the rotating shaft, thus achieving drilling angle positioning. This saves the time required for complex manual calculations of the drilling angle and improves construction efficiency.

[0009] Optionally, the telescopic assembly further includes a fixed cylinder and a first threaded rod threadedly connected to the fixed cylinder, the top end of the fixed cylinder being fixedly connected to the crossbeam, and the ring being fixedly connected to the bottom end of the first threaded rod.

[0010] In this scheme, rotating the first threaded rod causes it to move axially along the fixed cylinder, thereby changing the length of the telescopic component and adjusting the distance between the ring and the slope, thus adjusting the tension of the wire rope.

[0011] Optionally, the first locking assembly includes a first fixing seat, on which a horizontally arranged second threaded rod is threadedly connected, with the end of the second threaded rod facing the circumferential wall of the first angle scale.

[0012] In this solution, rotating the second threaded rod causes it to move towards or away from the first angle scale, thereby fixing or releasing the first angle scale.

[0013] Optionally, the second pointer is fixedly connected to the first mounting base.

[0014] In this design, the second pointer is designed on the first fixed base so that the second pointer is not affected by the second threaded rod when indicating the scale on the first angle dial.

[0015] Optionally, the second locking assembly includes a second fixed seat, on which a third threaded rod is threadedly connected, with the end of the third threaded rod facing the rotation axis.

[0016] In this scheme, rotating the third threaded rod causes it to move towards or away from the rotation axis, thereby fixing or releasing the rotation axis.

[0017] Optionally, a rubber layer is provided on the circumferential wall of the rotating shaft.

[0018] In this design, the rubber layer is elastic. Therefore, when the end of the third threaded rod moves towards the direction of the rotating shaft, the end of the third threaded rod abuts against the rubber layer and sinks into the rubber layer, increasing the clamping force applied to the rotating shaft and improving the fixing effect of the rotating shaft.

[0019] Optionally, a second angle scale is fixedly connected to the crossbeam, and a cylinder is coaxially connected to the second angle scale. A thin rope is provided on the cylinder, and a gravity hammer is connected to the bottom end of the thin rope.

[0020] In this scheme, after the support frame is placed on the slope, the gravity hammer is always perpendicular to the horizontal plane. Therefore, when the gravity hammer is stationary, the slope inclination angle can be obtained by observing the angle indicated by the thin rope on the second angle scale. There is no need to measure the slope inclination angle in advance, which reduces the workload and improves construction efficiency.

[0021] Optionally, the string coincides with the zero mark of the second angle dial.

[0022] In this scheme, the thin rope initially coincides with the zero mark of the second angle scale. Thus, after the support frame is placed on the slope, the angle indicated by the thin rope on the second angle scale is the slope inclination angle, and it is not necessary to calculate the slope inclination angle again.

[0023] Optionally, the rotating shaft is provided with a threaded section and a limiting disk, the first angle scale is located between the threaded section and the limiting disk, and the locking element is a threaded cylinder, which is threadedly connected to the threaded section.

[0024] In this solution, rotating the threaded cylinder causes the first angle scale to be pressed between the threaded cylinder and the limiting plate, which allows the first angle scale to rotate with the rotating shaft; rotating the threaded cylinder in the opposite direction releases the first angle scale, making the operation simple.

[0025] Optionally, a number of limiting pins are fixedly connected to the base.

[0026] In this design, the limiting pins on the base can be inserted under the slope to share the downward force of the support frame along the slope, thereby further improving the stability of the support frame on the slope. Attached Figure Description

[0034] Example 1

[0035] This embodiment is basically as follows: Figures 1 to 4 As shown: Angle adjustment frame for a smooth blasting drilling machine, including a drilling machine mounting base 1 and a support frame 2 for supporting the drilling machine mounting base 1. In this embodiment, combined with... Figure 2 As shown, there are two support frames 2, namely a left support frame and a right support frame, which are connected by a connecting plate 3. Both the left and right support frames include a base 201, a support column 202, and a crossbeam 203. The top end of the support column 202 is welded to the crossbeam 203, and the bottom end of the support column 202 is welded to the base 201. Several limiting pins 4 are welded to the bottom surface of the base 201. A telescopic assembly 5 is provided on the crossbeam 203. The telescopic assembly 5 includes a ring 501, a fixed cylinder 502, and a first threaded rod 503 threadedly connected to the fixed cylinder 502. The top end of the fixed cylinder 502 is welded to the crossbeam 203, and the bottom end of the ring 501 is welded to the first threaded rod 503. A steel wire rope 6 passes through the ring 501, and the two ends of the steel wire rope 6 are fixed to the top and bottom of the slope 20, respectively. A cylinder 7 for the steel wire rope 6 to pass through is welded onto the crossbeam 203 or the support column 202. In this embodiment, the cylinder 7 is welded to the support column 202. In addition, in this embodiment, the number of telescopic components 5 in both the left and right support frames is four, the number of support columns 202 and cylinders 7 is two, and the number of steel wire ropes 6 is two, which pass through the cylinder 7 and the ring 501 in the left and right support frames, respectively.

[0036] The drilling machine mounting base 1 has mounting holes evenly distributed along its circumference. A shock-absorbing pad 8 is mounted on the mounting base 1, and the shock-absorbing pad 8 has through holes 801 corresponding to the mounting holes. An arc-shaped limiting plate 101 is integrally formed on the top surface of the drilling machine mounting base 1. Lateral support plates 9 are welded to both sides of the drilling machine mounting base 1. A rotating shaft 10 is welded to the lateral support plates 9. The rotating shaft 10 is rotatably connected to the crossbeam 203. A first angle scale 11 is coaxially rotatably connected to the rotating shaft 10. The rotating shaft 10 is equipped with a locking component for fixing the first angle scale 11. Figure 2 As shown, in this embodiment, the rotating shaft 10 is provided with a threaded section 12 and a limiting disk 13. The limiting disk 13 is welded to the rotating shaft 10. The first angle scale 11 is located between the threaded section 12 and the limiting disk 13. The locking element is a threaded cylinder 14, which is threadedly connected to the threaded section 12 on the rotating shaft 10. The rotating shaft 10 is provided with a first pointer 15 for indicating the first angle scale 11, which is welded to the limiting disk 13. The crossbeam 203 is provided with a second pointer 16 for indicating the first angle scale 11. Both the first pointer 15 and the second pointer 16 are horizontally arranged and both point to the 90° scale line of the first angle scale 11. In addition, in this embodiment, the zero scale line of the first angle scale 11 is located at the bottom of the surface of the first angle scale 11.

[0037] The crossbeam 203 is also provided with a first locking assembly 17 for fixing the first angle scale 11 and a second locking assembly 18 for fixing the rotating shaft 10. In this embodiment, there are two sets of first locking assemblies 17, located on both sides of the first angle scale 11. Each first locking assembly 17 includes a first fixing seat 171, which is welded to the crossbeam 203. A horizontally arranged second threaded rod 172 is threadedly connected to the first fixing seat 171, with one end of the second threaded rod 172 near the first angle scale 11 facing the circumferential wall of the first angle scale 11. In addition, in this embodiment, the second pointer 16 is welded to the first fixing seat 171.

[0038] Combination Figure 2 and Figure 3As shown, there are four sets of second locking components 18, which are evenly distributed around the circumference of the rotation axis 10. Each second locking component 18 includes a second fixing seat 181, which is welded to the crossbeam 203. A third threaded rod 182 is threadedly connected to the second fixing seat 181, and the third threaded rod 182 is arranged radially along the rotation axis 10. In addition, to improve the fixing effect of the second locking components 18 on the rotation axis 10, a rubber layer 19 is adhered to the circumferential wall of the rotation axis 10. In this embodiment, the ends of the second threaded rod 172 and the third threaded rod 182 are provided with cross grooves so that construction personnel can use tools such as screwdrivers to rotate the second threaded rod 172 and the third threaded rod 182.

[0039] In practical use, the construction personnel first place the support frame 2 on the slope surface of the slope 20 according to the excavation boundary, and fix the top of the steel wire rope 6 on the support frame 2 to the top of the slope 20, and fix the bottom of the steel wire rope 6 on the support frame 2 to the bottom of the slope 20 to complete the preparation work.

[0040] Next, the construction workers rotate the first threaded rod 503, causing it to move downwards along the axial direction of the fixed cylinder 502. This applies downward pressure to the wire rope 6 through the ring 501, increasing its tension. With the wire rope 6 tighter, the support frame 2 is subjected to a downward pressure perpendicular to the slope, thus stabilizing it on the slope and eliminating the need for ground anchors. This method is convenient and simple. Furthermore, when the support frame 2 needs to be moved, simply rotate the first threaded rod 503 in the opposite direction, causing it to move upwards along the axial direction of the fixed cylinder 502. This reduces the tension of the wire rope 6, allowing the support frame 2 to be moved. In other words, in this embodiment, the support frame 2 is easy to assemble and disassemble, has high construction efficiency, and provides good fixation. Additionally, the limiting pins 4 on the base 201 are inserted into the slope, further enhancing the fixation effect of the support frame 2. Furthermore, since the first threaded rod 503 drives the ring 501 to rotate, and the wire rope 6 passes through the ring 501, the wire rope 6 is twisted around the outside of the ring 501 during the rotation of the ring 501, which can position the support frame 2 and prevent the support frame 2 from sliding down the slope. When the first threaded rod 503 drives the ring 501 to rotate in the opposite direction, the twisting of the wire rope 6 can be released, and the support frame 2 can move along the wire rope 6 on the slope.

[0041] In the above process, after the support frame 2 is placed on the slope, because the rotating shaft 10 is rotatably connected to the crossbeam 203, when the crossbeam 203 is parallel to the slope, a relative rotation occurs between the rotating shaft 10 and the crossbeam 203, and the second pointer 16 no longer points to the 90° mark on the first angle dial 11. Next, the construction worker rotates the drilling machine mounting base 1. During this process, because the first angle dial 11 is pressed between the threaded cylinder 14 and the limiting plate 13, the first angle dial 11 rotates together with the rotating shaft 10 until the angle indicated by the second pointer 16 is the sum of 90° and the inclination angle of the slope 20 (the inclination angle of the slope 20 is measured in advance by the construction worker), ensuring that the 90° indicated by the first pointer 15 at this time is the drilling angle. Figure 4 As shown.

[0042] Then, the operator rotates the second threaded rod 172, causing its end to press against the circumferential wall of the first angle scale 11, thus fixing the first angle scale 11 and preventing it from rotating with the rotating shaft 10. Therefore, when the operator rotates the rotating shaft 10, the angle indicated by the first pointer 15 on the limit plate 13 is the drilling angle. When the operator rotates the rotating shaft 10 to the preset drilling angle indicated by the first pointer 15, the operator rotates the third threaded rod 182, causing its end to press against the rubber layer 19 on the rotating shaft 10, fixing the rotating shaft 10 and achieving the drilling angle positioning. Finally, the operator installs the drilling machine on the drilling machine mounting base 1 to begin drilling.

[0043] After drilling is completed, the tension of the wire rope 6 is reduced by the telescopic component 5 (the wire rope 6 is slack), allowing the construction personnel to move the support frame 2 to the next drilling position. If the drilling angle needs to be adjusted, the construction personnel rotate the third threaded rod 182 in the opposite direction to release the second locking component 18 from fixing the rotating shaft 10, allowing the rotating shaft 10 to rotate. The drilling angle is then read by the first pointer 15. When the angle indicated by the first pointer 15 is the drilling angle, the third threaded rod 182 is rotated again to fix the rotating shaft 10, allowing drilling to continue.

[0044] In summary, in this embodiment, by adjusting the tension of the wire rope 6 using the telescopic component 5, the support frame 2 can be stably fixed to the slope or released from fixation. The support frame 2 is easy to assemble and disassemble on the slope, improving construction efficiency. Furthermore, when the wire rope 6 is tightened, it not only applies pressure to the support frame 2 up to the slope but also prevents the support frame 2 from sliding down the slope, ensuring effective fixation. In addition, the angle indicated by the first pointer 15 is the drilling angle. Adjusting the drilling angle is simple, and the second locking component 18 can be used to position the drilling angle, ensuring stable drilling after the drilling machine is installed and preventing deviations during the drilling process.

[0045] Example 2

[0046] The difference between this embodiment and Embodiment 1 is that: Figure 5 As shown, in this embodiment, a second angle scale 21 is welded onto the crossbeam 203, and a cylinder 22 is coaxially welded onto the second angle scale 21. A thin rope 23 is bound to the cylinder 22, and a gravity hammer 24 is connected to the bottom end of the thin rope 23. The thin rope 23 coincides with the zero mark line of the second angle scale 21.

[0047] In this embodiment, after the construction workers place the support frame 2 on the slope, the thin rope 23 is perpendicular to the horizontal plane when the gravity hammer 24 is stationary. Therefore, when the gravity hammer 24 is stationary, the angle indicated by the thin rope 23 is the angle of inclination of the slope 20. The construction workers do not need to measure the angle of inclination of the slope 20 in advance, which reduces the workload and improves the construction efficiency.
