Description

Technical Field

[0001] This utility model relates to the field of tunnel blasting technology, specifically to a laser drilling angle controller. Background Technology

[0002] In tunnel blasting construction, the drill-and-blast method is one of the most important methods. Besides large-scale drilling machines, pneumatic-legged drilling rigs are currently mainly used for manual drilling. However, manual drilling has significant drawbacks. It relies heavily on the experience of the drilling operators, making it difficult to guarantee the accuracy of the drilling angle. Large deviations in the borehole angle can lead to unsatisfactory blasting results, resulting in a waste of manpower, materials, and financial resources. Therefore, controlling the drilling angle through a control device can ensure the accuracy of manual drilling, which is of great significance for further optimizing blasting plans, improving blasting effects, and achieving safe, precise, and efficient blasting.

[0003] Patent application CN202323041805.4 discloses a blasting borehole angle control device. This device achieves precise positioning of the borehole angle by adjusting the angle adjustment bracket and drill rod fixing component on the base. It also features a simple and reusable overall structure, offering some economic benefits. However, when applied to open-pit blasting construction, this device can only achieve angle control in one direction and requires a high degree of flatness of the contact surface. Patent application CN202111427340.9 discloses a high-efficiency borehole angle measurement device for tunnel blasting. This device uses leveling mechanisms fixed on both sides of the bottom surface of the main protractor body for leveling parallel to the tunnel face. It allows for quick measurement of the borehole angle by changing the probe rod of different diameters for different blast holes using a quick-release sleeve and locking mechanism. However, this device has limitations in handling uneven tunnel faces and cannot achieve precise control of the borehole angle during drilling. Patent application CN202110098730.X discloses an auxiliary device for precise control of the angle of tunnel blasting boreholes. This device adjusts the level of the device through a support leg assembly and a horizontal indicator mechanism set on a horizontal angle scale. The horizontal and vertical rotation angles of the sleeve are controlled by the horizontal and vertical angle adjustment assemblies, respectively, and the borehole depth is indicated by a ranging mechanism, enabling accurate calibration of the borehole angle and depth. However, this device has a certain distance from the tunnel face, making borehole positioning relatively complex. Furthermore, the greater the drilling height, the greater the distance, placing certain requirements on the drill rod length. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a laser drilling angle controller.

[0005] The technical solution of this utility model is as follows:

[0006] A laser drilling angle controller for adjusting the drilling angle of a drilling rig includes an annular base and an annular angle adjustment plate rotatably connected to the base. The angle adjustment plate is coaxial with the base and can rotate around the central axis. The base is provided with a first locking structure that can lock the angle adjustment plate.

[0007] Multiple leveling columns are installed on the base, and the multiple leveling columns are evenly spaced along the circumference of the base and can slide along the axial direction of the base. The base is provided with a second locking structure that can lock the leveling columns, and the angle adjustment plate is provided with a leveling display.

[0008] An angle plate is provided on the angle adjustment plate, and a drilling rig mounting frame is rotatably connected to the angle plate.

The drilling rig mounting frame is provided with a third locking structure that can lock the position of the drilling rig mounting frame.

[0009] A support frame is attached to the base.

[0010] Furthermore, the leveling display includes an adjustment platform connected to the angle adjustment plate, the adjustment platform having a leveling bubble, and the leveling display is configured such that when the leveling bubble indicates horizontal, the surface of the angle plate is horizontal or vertical.

[0011] Furthermore, the adjustment platform is located on a radial plane of the angle adjustment plate, and is configured such that when the leveling bubble indicator is horizontal, the adjustment platform corresponds horizontally to the central axis of the angle adjustment plate.

[0012] Furthermore, the base includes a coaxial annular chassis and an annular outer shell, which are connected to each other. The chassis has a rotating groove on the side near the outer shell, and the angle adjustment plate is located in the rotating groove and its outer contour matches the contour of the rotating groove.

[0013] Furthermore, a lower rolling groove is provided on the bottom surface of the rotating groove, and an upper rolling groove is provided on the plate surface of the angle adjusting plate near the bottom surface of the rotating groove. The lower rolling groove and the upper rolling groove correspond to each other and are provided with a number of balls in the space formed by their cooperation. A washer is provided between the bottom surface of the rotating groove and the angle adjusting plate. A number of bead holes are distributed circumferentially on the washer, and the balls rotate in the bead holes respectively.

[0014] Furthermore, the angle plate and the leveling display are located on the outside of the housing, and are both fixedly connected to the surface of the angle adjustment plate through a connecting part located inside the inner hole of the housing.

[0015] Furthermore, the second locking structure includes a clamping ring and screws threaded onto the housing. The clamping ring surrounds the outside of all leveling posts, and the screws abut against and force the clamping ring to undergo radial deformation, thus locking all leveling posts.

[0016] Furthermore, the outer casing is provided with a receiving groove, the outer ring surface of the chassis is threaded to the side wall of the receiving groove, and the outer ring surface of the chassis is provided with a ring-cut groove near the bottom of the receiving groove.

[0017] Furthermore, the support frame includes at least two support rods, the length of which is adjustable and one end is connected to the base.

[0018] Furthermore, the drilling rig mounting frame includes a telescopic rod, one end of which is rotatably connected to an angle plate, and the other end of which is equipped with a drilling rig mounting section.

[0019] The laser drilling angle controller provided by this utility model has the following effects:

[0020] 1. Through the angle adjustment plate, angle plate and leveling column, multi-directional adjustment of three axes (front and back, left and right and up and down) and multiple combinations can be achieved.

[0021] 2. With multiple leveling columns that can be independently extended and slid, it can easily and quickly level the surface of the tunnel when facing uneven surfaces.

[0022] 3. The leveling column passes through the base and can slide axially, making its length adjustable when facing the working face. This allows the base to be close to the working face, reducing the difficulty of blast hole alignment and the length requirements of the drilling rig's rotating rod. Attached Figure Description

[0029] Example 1:

[0030] like Figures 1 to 3 As shown, this embodiment provides a laser drilling angle controller for adjusting the drilling angle of a drilling machine. Specifically, it includes an annular base 1 and an annular angle adjustment plate 2 rotatably connected to the base 1. The angle adjustment plate 2 is coaxial with the base 1 and can rotate around the central axis. The base 1 is provided with a first locking structure 11 that can lock the angle adjustment plate 2.

[0031] Specifically, such as Figure 2 As shown, the base 1 includes a coaxial annular base 12 and an annular outer shell 13, which are connected to each other. The base 12 has a rotating groove 121 on the side near the outer shell 13. The angle adjustment plate 2 is located in the rotating groove 121 and its outer contour matches the contour of the rotating groove 121. The rotating groove 121 limits the rotation of the angle adjustment plate 2.

[0032] A lower rolling groove 122 is provided on the bottom surface of the rotating groove 121, and an upper rolling groove 21 is provided on the surface of the angle adjusting plate 2 near the bottom surface of the rotating groove 121. Both the lower rolling groove 122 and the upper rolling groove 21 are annular grooves and coaxial with the angle adjusting plate 2. A plurality of balls 3 are provided in the space formed by the lower rolling groove 122 and the upper rolling groove 21 corresponding to each other. A washer 4 is provided between the bottom surface of the rotating groove 121 and the angle adjusting plate 2. A plurality of ball holes are distributed circumferentially on the washer 4, and the balls 3 rotate in the ball holes respectively. The angle adjusting plate 2 is rotatably connected to the base 12 of the ball 3, which reduces the frictional resistance when the angle adjusting plate 2 rotates.

[0033] In this embodiment, the outer casing 13 is provided with a receiving groove 131, and the outer circumferential surface of the chassis 12 is threadedly connected to the side wall of the receiving groove 131. During installation, the chassis 12 is located in the receiving groove 131, and the outer casing 13 restricts the angle adjustment plate 2 within the rotation groove 121.

[0034] The first locking structure 11 includes a threaded hole and a screw. The threaded hole of the first locking structure 11 is formed on the housing 13 and extends axially along the housing 13. The screw is connected to the threaded hole and can press against the surface of the angle adjustment plate 2 to lock the position of the angle adjustment plate 2. The screw can be a long-ear screw, a claw screw, or other capped hand screw.

[0035] Combination Figure 1 and Figure 2 As shown, the angle adjustment plate 2 is provided with an angle plate 22, and a drilling rig mounting frame 23 is rotatably connected to the angle plate 22. The rotation axis of the drilling rig mounting frame 23 is perpendicular to the plate surface of the angle adjustment plate 2 and orthogonal to the central axis of the angle adjustment plate 2. The drilling rig mounting frame 23 is provided with a third locking structure 24 that can lock the position of the drilling rig mounting frame 23.

[0036] Specifically, the angle plate 22 is located on the outer side of the housing 13 away from the chassis 12, and it is fixedly connected to the surface of the angle adjustment plate 2 through a connecting part.

[0037] In this embodiment, the inner diameters of the chassis 12, washer 4, and angle adjustment plate 2 are the same, while the inner diameter of the outer casing 13 is larger than that of the angle adjustment plate 2. The connecting part is located inside the inner hole of the outer casing 13 and is connected to the plate surface of the angle adjustment plate 2 near the edge of the inner hole.

[0038] The angle plate 22 is semi-circular, with its chord edge connected to the angle adjustment plate 2 via a connecting part, and its arc edge arching away from the angle adjustment plate 2. The surface of the angle plate 22 has rounded corner markings along the arc edge.

[0039] The drilling rig mounting frame 23 includes a telescopic rod 231, one end of which is rotatably connected to the center of the angle plate 22, and the other end is provided with a drilling rig mounting part. The telescopic rod 231 swings along the surface of the angle plate 22 to adjust the drilling angle of the drilling rig according to actual needs and the rounded corner scale on the angle plate 22.

[0040] The third locking structure 24 is the same as the first locking structure 11, also including a threaded hole and a screw. The threaded hole of the third locking structure 24 is located on the telescopic rod 231, corresponding to the surface of the angle plate 22. The screw connects to the threaded hole and can be screwed in perpendicular to the angle plate 22, pressing against the surface of the angle adjustment plate 2 and locking the position of the drill mounting bracket 23. The screw is preferably a long-ear screw, a claw screw, or other capped hand-tightening screw for easy manual adjustment.

[0041] In this embodiment, to provide more stable support for the drilling rig, two angle plates 22 are included, symmetrically arranged relative to the central axis of the angle adjustment plate 2, and the two angle plates 22 are parallel to each other. The drilling rig mounting frame 23 includes two telescopic rods 231, which are respectively connected to the two angle plates 22, and the two telescopic rods 231 are connected and reinforced by a fixing ring 232. The two telescopic rods 231 are respectively connected to two symmetrical quadrant points on the fixing ring 232.

[0042] Please combine Figures 1 to 3 As shown, a plurality of leveling columns 5 are mounted on the base 1. The leveling columns 5 are evenly spaced around the base 1 and can slide along the axial direction of the base 1. The base 1 is provided with a second locking structure 14 that can lock the leveling columns 5. The angle adjustment plate 2 is provided with a leveling display component 25. The multiple leveling columns 5 can extend and retract independently, and can also be extended and retracted in a targeted manner to flatten the base 1 when facing an uneven working surface.

[0043] Specifically, sliding holes are provided at the radial outer edges of both the chassis 12 and the outer casing 13 for the leveling columns 5 to pass through and slide. The leveling columns 5 are distributed on the radial outer side of the angle adjustment plate 2, with more than 6 columns, and their length is preferably 2-3 times the axial thickness of the base 1. Anti-detachment heads are provided at both ends of the leveling columns 5.

[0044] The second locking structure 14, like the first locking structure 11 and the third locking structure 24, includes a threaded hole and a screw. Furthermore, the second locking structure 14 also includes a retaining ring 141, such as... Figure 3 As shown.

[0045] like Figure 2 and Figure 3 As shown, the outer ring surface of the chassis 12 has a ring-cut groove 123 near the bottom of the receiving groove 131. The leveling column 5 passes through the ring-cut groove 123, and the clamping ring 141 is located inside the ring-cut groove 123 and surrounds the outside of all the leveling columns 5. The inner ring surface of the clamping ring 141 is close to the cylindrical surface of the leveling column 5. The clamping ring 141 is preferably made of a material with a certain degree of rigidity and ductility. In this embodiment, the clamping ring 141 is a thin steel ring with a sufficiently thin radial thickness to meet the requirement of radial deformation, while the steel itself has high rigidity and wear resistance to meet the requirements of preventing the clamping ring 141 from being torn apart and the toughness requirement of restoring its shape.

[0046] The threaded hole of the second locking structure 14 is opened on the outer ring surface of the housing 13, and its position corresponds radially to the clamping ring 141, and corresponds to the position between any two adjacent leveling posts 5. The screw of the second locking structure 14 is connected to the threaded hole, and can abut and force the clamping ring 141 to produce radial deformation. Due to the local bending deformation of the clamping ring 141, the other parts of the clamping ring 141 are pulled to the deformation position, locking all the leveling posts 5.

[0047] The annular groove 123 is not only used to accommodate the clamping ring 141, but also saves internal space occupied by the receiving groove 131, reduces the axial thickness of the base 1, and lowers the overall size and weight of the base 1. Furthermore, the annular groove 123 is located on the side of the chassis 12 near the bottom of the receiving groove 131. Compared to assuming it is located in the middle of the outer circumference of the chassis 12, this allows for greater thickness on the side of the chassis 12 away from the bottom of the receiving groove 131, facilitating thread machining.

[0048] It should be noted that, for clarity, the screws of the first locking structure 11, the second locking structure 14, and the third locking structure 24 are not shown in the accompanying drawings of this application.

[0049] For example Figure 1 and Figure 2As shown, the leveling display 25 indicates whether the laser drilling angle controller has been adjusted to a horizontal position. The leveling display 25 is also located on the outer side of the housing 13 away from the chassis 12, and is fixedly connected to the surface of the angle adjustment plate 2 via a connecting part, and is also connected to the surface of the angle adjustment plate 2 near the edge of the inner hole. The connecting part of the leveling display 25 is also located inside the inner hole of the housing 13.

[0050] The leveling display component 25 specifically includes an adjustment platform 251 connected to the angle adjustment plate 2, and a leveling bubble 252 is provided on the adjustment platform 251 to indicate whether it has been leveled.

[0051] The leveling indicator 25 is configured such that when the leveling bubble 252 indicates horizontal, the angle plate 22 is horizontal or vertical. At this time, rotating the drill mounting bracket 23 allows adjustment of the drill's angle in the horizontal or vertical plane. In this embodiment, the leveling indicator 25 is configured such that when the leveling bubble 252 indicates horizontal, the angle plate 22 is horizontal.

[0052] Furthermore, the adjustment platform 251 is located on a radial plane of the angle adjustment plate 2, and is configured such that when the leveling bubble 252 indicates horizontal, the adjustment platform 251 corresponds horizontally to the central axis of the angle adjustment plate 2. A pointer is provided on the side of the adjustment platform 251 away from the central axis of the angle adjustment plate 2, and the surface of the outer casing 13 near the adjustment platform 251 is provided with rounded graduations, which cooperate with the pointer for adjusting the rotation angle of the angle adjustment plate 2.

[0053] The leveling bubble 252 includes a hemispherical cover containing liquid and bubbles. When the bubble is located at the top of the hemispherical sphere, it indicates that the laser drilling angle controller has been leveled.

[0054] It should be noted that the angle dial and leveling display 25 do not interfere with the first locking element and leveling column 5 when they rotate with the angle adjustment dial.

[0055] For example Figure 1 As shown, a support frame 6 is connected to the base 1. The support frame 6 specifically includes two support rods 61. The length of the support rods 61 is adjustable, and one end is rotatably connected to the base 1, with the axis of rotation extending horizontally in a direction perpendicular to the central axis of the base 1. In some other embodiments, there may be more than two support rods 61.

[0056] The laser drilling angle controller in this embodiment, through the angle adjustment plate 2, the angle plate 22 and the leveling column 5, can realize multi-directional adjustment of three axes (front and back, left and right, and up and down) in various combinations. With the leveling display 25, it can perform initial leveling operation and adjust the drilling angle of the rotating rod of the machine more accurately.

[0057] In addition, by independently extending and sliding multiple leveling columns 5, it is possible to easily and quickly level the surface when facing uneven working surfaces.

[0058] In addition, the leveling column 5 passes through the base 1 and can slide axially, so that its length is adjustable when facing the working face, allowing the base 1 to be close to the working face, reducing the difficulty of blast hole alignment and the length requirements of the drilling rig's rotating rod.

[0059] Example 2:

[0060] In this embodiment, as Figure 1 As shown, this embodiment is basically the same as the first embodiment, except that a laser emitter 7 is provided on the side of the outer shell 13 away from the chassis 12, which is used to perform laser scanning on the surface to be constructed to obtain local features of the surface to be constructed, so as to provide data support for the angle adjustment of the drilling rig rod.
