Description

Technical Field

[0001] The invention relates to the technical field of peripheral eye drilling and blasting methods, and in particular to a slotting drilling rig structure that realizes the energy gathering function of a tunnel peripheral eye. Background Art

[0002] Peripheral drilling and blasting is a blasting method used in tunnel construction. In tunnel engineering, peripheral drilling and blasting is usually used to reduce the impact on the surrounding environment and structure and to ensure the stability and safety of the tunnel.

[0003] The basic principle of this method is to dig a series of small holes (called eye holes) around the tunnel, and then place energy-gathering tubes in these eye holes, place blasting charges in the energy-gathering tubes, and blast after connecting the fuse. In this way, the blasting charges will produce a controlled blasting effect in the surrounding strata, breaking the rock into smaller pieces, thereby reducing the impact on the surrounding structure while ensuring the overall stability of the tunnel.

[0004] The existing method of drilling holes in the smooth surface of the tunnel manually using a drill rig will firstly reduce the positioning accuracy of the eyelet, resulting in affected blasting effects. Secondly, blasting charges are placed in the hole opening by inserting a focused tube filled with charges into the eyelet and pushing the focused tube into the eyelet through a rod. This operation is cumbersome and reduces efficiency. At the same time, manual placement of charges is dangerous. Finally, manual operation requires the construction of a frame, which increases costs. Summary of the invention

DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Reference Figure 1-Figure 16 A grooving drilling rig structure for realizing the tunnel periphery eye focusing function includes a drilling trolley 1, and also includes an automatic moving guide rail 11 installed on the machine arm of the drilling trolley 1, a drilling device, a feeding device and a pushing device.

[0051] The automatic moving guide rail 11 is composed of a guide rail installed on the rock drilling trolley 1, a screw rod, and a motor that drives the screw rod to rotate.

[0052] like Figure 2-Figure 7 As shown, in order to automatically drill holes in the tunnel wall, a drilling device is provided. The drilling device is located on the outer surface of the automatic moving guide rail 11, and automatically drills the positioned hole. The drilling device includes a positioning mechanism and an expanding mechanism. The positioning mechanism includes a positioning drill rod 21, and the rotation of the positioning drill rod 21 positions the hole. The expanding mechanism includes an expanding drill pipe 32, and the rotation of the expanding drill pipe 32 expands the hole drilled by the positioning drill rod 21.

[0053] Specifically, in order to automatically perform positioning work, the positioning device includes a moving seat 2, the lower surface of the moving seat 2 is slidingly connected to the outer surface of the slide rail of the automatic moving guide rail 11 and is threadedly connected to the outer surface of the screw rod of the automatic moving guide rail 11, one end of the positioning drill rod 21 is fixedly installed on the outer surface of the moving seat 2 through a bearing, and the outer surface of the moving seat 2 is fixedly installed with a positioning motor 22 that drives the positioning drill rod 21 to rotate.

[0054] Specifically, in order to control the rotation of the expansion drill pipe 32, an adjustment seat 3 is slidably connected to the outer surface of the slide rail of the automatic moving guide rail 11, and the outer surface of the adjustment seat 3 is fixedly installed with the outer surface of the expansion drill pipe 32 through a bearing. In order to drive the rotation of the expansion drill pipe 32 to perform the expansion work, a rotating motor 31 with a shell is fixedly installed on the upper surface of the adjustment seat 3. One end of the output shaft of the rotating motor 31 drives the rotation of the expansion drill pipe 32 through a gear set. The gear set is composed of two meshing gears, and the two gears are fixedly installed with the output shaft of the rotating motor 31 and one end of the expansion drill pipe 32 respectively. In order to position the drill rod 21 is supported during drilling, a limiting ring 33 with balls is fixedly installed on the inner wall of the expansion drill pipe 32, and the balls are rotatably connected to the inside of the limiting ring 33. After the positioning drill rod 21 moves, it is slidably connected to the outer surface of the balls of the limiting ring 33. There are three balls on the limiting ring 33, and the length of the inner wall protruding from the limiting ring 33 is 2-3 mm, which reduces the influence of the balls on the movement of the energy-gathering tube. One end of the expansion drill pipe 32 is provided with a drill pipe with a trapezoidal cross-section, and the inner wall diameter of the drill pipe is slightly larger than the diameter of the positioning drill rod 21, which is convenient for the expansion drill pipe 32 to expand the edge and prevents gravel from entering the inside of the expansion drill pipe 32.

[0055] Specifically, in order to flexibly control the movement of the expansion drill pipe 32, a threaded sleeve 34 is fixedly installed on the inner wall of the adjustment seat 3 through a bearing, and the inner wall of the threaded sleeve 34 is threadedly connected to the outer surface of the screw rod of the automatic movable guide rail 11. The inner wall of the adjustment seat 3 is slidably inserted with an electromagnet 35 through a limit rod, and the outer surface of the limit rod is fixedly installed with a reset spring 36 for forcing the electromagnet 35 to reset. The outer surface of the threaded sleeve 34 is fixedly installed with an adsorption groove 37 through a groove, and the outer surface of the electromagnet 35 is magnetically connected to the inner wall of the adsorption groove 37. When driving the adjustment seat 3 to move, after the electromagnet 35 is magnetically connected to the adsorption groove 37, the threaded sleeve 34 is limited, and the rotation of the screw rod drives the threaded sleeve 34 and the adjustment seat 3 to move. After the electromagnet 35 is powered off, the rotation of the screw rod drives the threaded sleeve 34 to rotate.

[0056] like Figure 8-Figure 12As shown, in order to automatically transport the energy-gathering tubes filled with blasting materials, a feeding device is provided. The feeding device is located on the outer surface of the frame of the drilling trolley 1, and transports the gunpowder group with the energy-gathering tubes to the drilling device. The feeding device includes a support plate 4, a conveying mechanism and a feeding mechanism. The conveying mechanism includes a fixed trough 51. The fixed trough 51 fixes the gunpowder group and drives the gunpowder group to move. The feeding mechanism includes a feeding trough 61. The movement of the feeding trough 61 drives the gunpowder group to be transported to the drilling device.

[0057] Specifically, in order to continuously convey the energy-gathering tube of blasting drugs, the support plate 4 is fixedly mounted on the outer surface of the frame of the drilling trolley 1, and the conveying mechanism also includes a rotating component 5, which is composed of a bracket, a motor, a synchronous wheel rotatably connected to the bracket, and a synchronous belt. The synchronous belt is driven to rotate by the rotation of the synchronous wheel driven by the motor. The rotating component 5 is fixedly mounted on the upper surface of the support plate 4, and the outer surface of the synchronous belt of the rotating component 5 is fixedly mounted on the outer surface of a plurality of fixed grooves 51. The cross-section of the plurality of fixed grooves 51 is in a semi-ring shape, which is convenient for the energy-gathering tube to leave. The excessively long leads on the energy-gathering tube can be tied with a cable tie first to facilitate the movement of the energy-gathering tube.

[0058] Specifically, in order to fix the energy-gathering tube, a fixing ring 52 with a gear ring is slidably inserted into the inner wall of the fixing groove 51, and a driving rod 53 with a driving gear is rotatably connected to one side of the fixing groove 51. The driving gear is fixedly installed on the driving rod 53, and the driving gear is meshed with the gear ring of the fixing ring 52.

[0059] Specifically, in order to transport the energy-gathering tube on the feeding trough 61 to one side of the expansion drill pipe 32, the feeding mechanism also includes a pushing hydraulic cylinder 6, which is fixedly installed on the outer surface of the bracket of the rotating component 5, and one end of the piston rod of the pushing hydraulic cylinder 6 is fixedly installed with the feeding trough 61 through a connecting piece. The pushing hydraulic cylinder 6 is located in the middle position of the driving component, so that when the synchronous belt rotates forward, the fixed trough 51 above the synchronous belt provides the feeding trough 61 on the right side of the synchronous belt, and the fixed trough 51 below the synchronous belt provides the feeding trough 61 on the left side of the synchronous belt. The energy-gathering tube is transported to the two feeding troughs 61 through one driving component, thereby accelerating the blasting efficiency.

[0060] Specifically, in order to automatically control the rotation of the fixed ring 52, an opening and closing motor 62 is fixedly installed on the outer surface of the connecting piece, an electromagnetic ring 63 is fixedly installed on one end of the output shaft of the opening and closing motor 62, and the outer surface of the electromagnet 35 is magnetically connected to one end of the driving rod 53.

[0061] like Figure 13-Figure 16As shown, in order to push the energy-gathering tube toward the eyelet, a pushing device is provided, which includes a fixed rack 73 for pushing and a pushing shell 72. The pushing device is located on the inner wall of the drilling position. After one end of the fixed rack 73 is inserted into one end of the positioning drill rod 21, the pushing shell 72 is driven by the positioning drill rod 21 to push the gunpowder group.

[0062] Specifically, in order to drive the lifting gear to automatically lift and lower, the pushing device also includes a support ring 7, which is fixedly mounted on the inner wall of the adjusting seat 3, and a fixed motor 71 is fixedly mounted on the inner wall of the adjusting seat 3. The inner wall of the pushing shell 72 is slidably plugged into the outer side surface of the fixed rack 73 to limit the fixed rack 73. One end of the fixed rack 73 of the pushing shell 72 is slidably plugged into the inner wall of the support ring 7 to fix the pushing shell 72. The other end of the fixed rack 73 is slidably plugged into one end of the positioning drill rod 21 through a groove to fix the pushing shell 72 on the positioning drill rod 21. The diameter of the energy-gathering tube is smaller than the positioning drill rod 21, which is convenient for passing the ball on the support ring 7.

[0063] Specifically, in order to drive multiple fixed racks 73 to rise and fall synchronously, a driving ring 74 is fixedly installed on the inner wall of the pushing shell 72 through a bracket, and a fixed gear 75 is fixedly installed on the outer surface of the driving ring 74 through a bearing. One end of the output shaft of the fixed motor 71 drives the fixed gear 75 to rotate through a gear, and the fixed gear 75 is meshed with the fixed rack 73. The outer surface of the fixed gear 75 is hinged with a connecting rod group 76 through a pin shaft.

[0064] Working principle: After manually placing the blasting energy-gathering tube to be placed on the fixed slot body 51, the drilling trolley 1 is started, and the position where the hole needs to be drilled is calculated, the arm of the drilling trolley 1 is moved to drive the positioning drill rod 21 and the eyelet of the drill hole to be located on the same axis line, and then the guide rail 11 is automatically moved. At the same time, after the electromagnet 35 on the moving seat 2 is energized, the rotation of the screw rod drives the threaded sleeve 34 to rotate. After the electromagnet 35 encounters the adsorption groove 37, one end of the electromagnet 35 is inserted into the adsorption groove 37, and the reset spring 36 is compressed. The electromagnet 35 fixes the moving seat 2 and the threaded sleeve 34, and the rotation of the screw rod can drive the adjustment seat 3 and the moving seat 2 to move;

[0065] After the expansion drill pipe 32 contacts the wall of the tunnel, the electromagnet 35 is powered off, and the electromagnet 35 is reset under the force of the reset spring 36, and the adsorption with the adsorption groove 37 is released. The rotation of the screw rod continues to drive the moving seat 2 to move, so that the positioning drill rod 21 is inserted into the expansion drill pipe 32. After the positioning motor 22 is started, the positioning drill rod 21 is driven to drill a hole at a position where a hole needs to be drilled. After the hole is drilled to a certain position, the electromagnet 35 continues to be energized, so that the threaded sleeve 34 drives the movement of the adjustment seat 3, and the rotating motor 31 is started at the same time, driving the expansion drill pipe 32 to rotate, and the hole drilled by the positioning drill rod 21 is expanded, so that the hole diameter reaches the set diameter. At the same time, the ball bearings on the limit ring 33 in the expansion drill pipe 32 support the positioning drill rod 21 to keep the positioning drill rod 21 stable, and the rotatable ball bearings do not affect the rotation of the positioning drill rod 21.

[0066] After the eyelet is opened, the positioning drill rod 21 leaves the expansion drill pipe 32 and stops at the set position. At the same time, the fixed motor 71 in the adjustment seat 3 is started, and the fixed gear 75 is driven to rotate through the gear. The fixed gear 75 drives other fixed gears 75 to rotate synchronously through the connecting rod group 76, and then drives the fixed rack 73 to descend. After one end of the fixed rack 73 leaves the groove of the support ring 7, it is inserted into the groove of the positioning drill rod 21, so that the pusher housing 72 is fixedly installed on the positioning drill rod 21. The positioning drill rod 21 moves away from the expansion drill pipe 32 under the drive of the automatic moving guide rail 11.

[0067] The rotating component 5 on the support plate 4 moves, pushing the hydraulic cylinder 6 to pull the feeding trough body 61 to retract and then be located below the fixed trough body 51 to reach the set position. After the electromagnetic ring 63 on the opening and closing motor 62 contacts one end of the driving rod 53, the electromagnetic ring 63 is energized and adsorbed with the driving rod 53. The opening and closing motor 62 drives the driving rod 53 to rotate by driving the electromagnetic ring 63, and the fixed ring 52 of the driving gear on the driving rod 53 rotates, thereby releasing the fixation of the energy-gathering tube in the fixed trough body 51, and the energy-gathering tube can fall into the feeding trough. After the feeding trough body 61 is pushed to one side of the expanding drill pipe 32 by pushing the hydraulic cylinder 6, the positioning drill rod 21 pushes the energy-gathering tube on the feeding trough body 61 under the drive of the automatic moving guide rail 11, and the pushing shell 72 pushes the energy-gathering tube into the expanding drill pipe 32 close to the limiting ring 33, the expanding drill pipe 32 and the expanding drill pipe 32 withdraw from the eyelet, completing the placement of the energy-gathering tube. At the same time, the driving component starts to drive the fixed trough body 51 on one side to rise, and the fixed trough body 51 on the other side descends, and the feeding trough body 61 is reset.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
