Abstract
Description
Technical Field
[0001] This utility model relates to the field of blasting technology, specifically to a multi-hole blasting drilling device. Background Technology
[0002] Smooth blasting is a controlled blasting technique that creates a smooth, flat excavation face without significant damage. Its key feature is drilling a row of smooth blasting holes along the designed excavation outline, with the spacing matching the minimum resistance line. Using decoupled charges or other special charge structures, the charges in the smooth blasting holes detonate simultaneously after the main excavation is completed, creating a smooth, flat excavation face that runs through all the smooth blasting holes. In actual smooth blasting, multiple blast holes are first drilled on the tunnel face using drilling equipment. These include peripheral holes, auxiliary holes, and central cut holes. The upper parts of the peripheral and auxiliary holes are arranged in an arc shape, while the lower parts are arranged in a straight line. The cut holes are arranged in a straight line. After drilling the holes on the blasting face, charges are loaded into each hole. After loading, drilling and blasting are carried out. Due to the large number of blast holes and their arrangement (including arc and straight lines), it is difficult to quickly locate and drill during the drilling process. Utility Model Content

Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0024] In one embodiment, see Figure 1The present invention relates to a multi-hole blasting drilling device, comprising a support frame, a lifting assembly, and a directional adjustment assembly.
[0025] The support frame includes a support base frame 1 and a support top frame 2 mounted on the support base frame 1.

The transmission member 5 is coaxially mounted with the support top frame 2, and the two sides of the lifting member 6 are clearance-fitted with the support top frame 2. The transmission member 5 rotates under external force, causing the lifting member 6 to move upward or downward along the axial direction of the transmission member 5. The steering assembly includes a circumferential adjusting member 7 mounted on the support top frame 2 and a rotating... A support member 8 is movably mounted on the lifting member 6.

[0026] Further, see Figure 1 The support base 1 includes a support base rod 101 and a support base plate 102 disposed at both ends of the support base rod 101. The support base rod 101 is provided with a movable wheel 103, and a connecting rod 13 is provided between the support base plate 102 and the support base rod 101. The fixing member 3 includes a fixing rod 301 movably disposed on the support base plate 102.
[0027] Preferably, the support base rod 101 is provided with a locking hole 14, the connecting rod 13 is provided with a locking stud 15 passing through the locking hole 14, and the locking stud 15 is provided with locking sleeves 16 located at the upper and lower ends of the support base rod 101.
[0028] Preferably, the support base plate 102 is provided with a fixing hole 302, and the fixing rod 301 is located in the fixing hole 302.
[0029] Further, see Figure 1 The support top frame 2 includes a support top rod 201 fixedly mounted on the support bottom rod 101, and the support top rod 201 is provided with a sliding groove 202; the reinforcing member 4 includes a reinforcing rod 401 whose two ends are fixedly connected to the support bottom rod 101 and the support top rod 201 respectively.
[0030] Preferably, the sliding groove 202 is arranged parallel to the axis of the support rod 201.
[0031] Preferably, the reinforcing rod 401 is welded to the supporting bottom rod 101 and the supporting top rod 201 to form a triangular stable support.
[0032] In the above setup, the moving wheel 103 can drive the support base 1 and the entire device to move, thereby adjusting the position. After the entire device is moved to the area to be drilled, the locking sleeve 16 is loosened and the connecting rod 13 is moved down so that the support base plate 102 abuts against the ground. Then, the locking sleeve 16 is used to fix the locking stud 15 to the support base rod 101, and holes are drilled in the ground. The fixing rod 301 is inserted into the holes in the ground and fixed, thereby fixing the entire device to the ground.
[0033] Further, see Figure 1 The transmission component 5 includes a transmission screw 501 rotatably disposed in the sliding groove 202 and a transmission motor 502 disposed on the support base rod 101.

[0034] Preferably, a support plate 19 is provided on the support base rod 101, and the drive motor 502 is mounted on the support plate 19.
[0035] Preferably, the depth of the sliding groove 202 is less than the diameter of the driven gear 18, and the width of the sliding groove 202 is greater than the diameter of the driven gear 18, so that some of the teeth of the driven gear 18 extend beyond the sliding groove 202 and mesh with the driving gear 17.
[0036] Further, see Figure 1 , 3 The lifting component 6 includes a lifting slider 601 disposed on the transmission screw 501, and the two sides of the lifting slider 601 are slidably connected to the sliding groove 202.
[0037] Preferably, the lifting slider 601 is provided with a lead screw hole 602, and the lifting slider 601 is connected to the transmission lead screw 501 through the lead screw hole 602.
[0038] In the above configuration, when the drive motor 502 is powered on and rotates clockwise, it drives the drive gear 17 to rotate. The drive gear 17 meshes with the driven gear 18, thereby driving the drive screw 501 to rotate. The rotation of the drive screw 501 drives the lifting slider 601 to move upward. The lifting slider 601 restricts the circumferential degree of freedom of the sliding groove 202, so that the lifting slider 601 can only move upward or downward along the drive screw 501.
[0039] Further, see Figure 1 , 2The circumferential adjusting component 7 includes a circumferential adjusting ring 701, a circumferential adjusting groove 702 on the circumferential adjusting ring 701, and a through groove 703 at the bottom end of the circumferential adjusting groove 702; the supporting component 8 includes a supporting slide rail 801, a rotating shaft 802 in the middle of the supporting slide rail 801, the rotating shaft 802 being rotatably connected to the lifting slider 601, and circumferential sliders 20 at both ends of the supporting slide rail 801, the circumferential sliders 20 sliding within the circumferential adjusting groove 702.
[0040] Preferably, the circumferential adjusting ring 701 and the lifting slider 601 are fixedly connected by a connecting rod 23.
[0041] Preferably, the width of the through groove 703 is smaller than the width of the circumferential adjustment groove 702.
[0042] Preferably, both the circumferential adjustment groove 702 and the circumferential slider 20 are arc-shaped structures.
[0043] Preferably, the middle part of the lifting slider 601 is provided with a rotating hole 21, and a first bearing 22 is provided in the rotating hole 21. The rotating shaft 802 is fixedly connected to the inner ring of the first bearing 22.
[0044] Further, see Figure 2 The first locking component 11 includes a first locking screw 1101 disposed on the circumferential slider 20. The first locking screw 1101 passes through the through groove 703 and is located outside the circumferential adjusting ring 701. A first locking nut 1102 is provided on the first locking screw 1101.
[0045] Preferably, a first locking plate 1103 is provided between the first locking screw 1101 and the first locking nut 1102 to increase the contact area with the circumferential adjusting ring 701.
[0046] In the above configuration, by rotating the support slide rail 801 along the rotating shaft 802, the position of the support slide rail 801 on the circumferential adjusting ring 701 can be adjusted, and the rotation angle of the support slide rail 801 can be controlled according to the angle scale 9, thereby adjusting the angle of the telescopic member 10 relative to the lifting slider 601. After the position of the support slide rail 801 is determined, the first locking nut 1102 is rotated to push the first locking plate 1103 to abut against the circumferential adjusting ring 701, thereby fixing the circumferential slider 20 in the circumferential adjusting groove 702. By having two sets of circumferential sliders 20 abut against the circumferential adjusting ring 701, the position of the support slide rail 801 on the circumferential adjusting ring 701 is fixed.
[0047] Further, see Figure 1 , 4The telescopic component 10 includes a telescopic rod 1001 slidably disposed within the support slide rail 801 and a fixing plate 1002 disposed within the support slide rail 801. The second locking component 12 includes an adjusting screw 1201 disposed on the fixing plate 1002, and the adjusting screw 1201 is rotatably connected to the telescopic rod 1001.
[0048] Preferably, the fixing plate 1002 is provided with an adjusting screw hole 1202, and the adjusting screw hole 1202 is threadedly connected to the adjusting screw 1201.
[0049] Preferably, the end of the telescopic rod 1001 facing the fixed plate 1002 is provided with a through hole, and a second bearing is provided in the through hole. The end of the adjusting screw 1201 is fixedly connected to the inner ring of the second bearing.
[0050] In the above configuration, by rotating the adjusting screw 1201, the adjusting screw 1201 moves within the support slide rail 801 under the action of the thread, thereby driving the telescopic rod 1001 to move out or into the support slide rail 801, and the distance between the telescopic rod 1001 and the lifting slider 601 can be adjusted.
[0051] In this embodiment, the external drilling equipment is bolted to the end of the telescopic rod 1001. During the drilling process, the position of the support rod 201 is determined according to the hole layout of the smooth blasting. The position of the support rod 201 is adjusted to be at the center of the peripheral holes. The entire device is fixed to the ground by the fixing rod 301. Rotating the support slide rail 801 can drive the drilling equipment to rotate circumferentially. Adjusting the length of the telescopic rod 1001 extending out of the support slide rail 801 can adjust the distance between the drilling equipment and the support rod 201, thereby adjusting the drilling equipment to correspond to the blast holes at different positions.
[0052] For example, when drilling peripheral holes, multiple sets of holes are arranged vertically in the lower part of the peripheral holes, while the holes in the upper part are arranged in an arc shape. First, the holes in the lower part of the peripheral holes are drilled. The support slide rail 801 is adjusted to be in a horizontal state, and the telescopic rod 1001 is adjusted to move the drilling equipment toward the tunnel sidewall, so that the drilling equipment is facing the vertical peripheral holes. The transmission motor 502 drives the transmission screw 501 to rotate, which can adjust the height of the drilling equipment, thereby completing the drilling of the straight blast holes in the lower part of the peripheral holes. For the blast holes in the upper part of the peripheral holes that are arranged in an arc shape, the drilling equipment can be rotated by rotating the support slide rail 801 along the circumferential adjustment ring 701, thereby completing the drilling of the blast holes in the upper part of the peripheral holes that are arranged in an arc shape.
[0053] For auxiliary holes, the drilling method is the same as that for peripheral holes.
[0054] For slotting holes, by adjusting the length of the telescopic rod 1001 extending beyond the support slide rail 801, and cooperating with the transmission screw 501 to drive the drilling equipment to move up or down, the slotting holes on one side (left side) of the support rod 201 can be drilled. For slotting holes on the other side (right side) of the support rod 201, the support slide rail 801 can be rotated so that the drilling equipment is located on the other side (right side) of the support rod 201, and the slotting holes can continue to be drilled.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
