Description

Technical Field

[0001] This invention relates to the field of engineering blasting technology, specifically to a multi-scenario adaptive telescopic boom charging positioning and hole control method. Background Technology

[0002] Engineering blasting is a civil blasting operation that uses the explosive energy of explosives to work on media such as rock, soil, and structures to achieve predetermined engineering goals such as breaking, loosening, and demolition. It is widely used in mining, water conservancy and transportation, infrastructure construction and demolition projects. Emulsion explosives are a type of water-containing industrial explosives with the characteristics of strong water resistance, good explosive performance, safety and stability, and low cost. They are the mainstream explosives in engineering blasting and are suitable for various blasting scenarios such as underwater, wet, open and underground. They are widely used in mining, tunnel and earthwork projects. In underground smooth blasting operations, because the blasting section is relatively high, drilling operations can be carried out by drilling equipment. However, the loading of explosive charges is mostly done manually by climbing up to fill them. Before filling, manual scaffolding needs to be erected. In addition to the danger of construction, the frequent dismantling and assembly of the scaffolding is time-consuming and labor-intensive, affecting the efficiency of blasting.

[0017] 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.

[0018] Please see the appendix Figure 1-8 This application provides the following technical solutions.

[0019] A multi-scenario adaptive telescopic boom charging positioning and orifice alignment control method includes the following steps: Step 1: At the site of underground smooth blasting, perform horizontal drilling using a drilling rig and clean up the debris generated during drilling. Step 2: Install a telescopic boom charging device on the mine explosion-proof trolley, and move the telescopic boom charging device to the blasting face using the mine explosion-proof trolley. Step 3: Adjust the position of the explosive by using the telescopic boom charging device, align the explosive with the charging hole, and then push the explosive into the charging hole, waiting for concentrated detonation.

[0020] The telescopic boom charging device includes a base platform 1, a lifting platform 2 movably mounted above the base platform 1, a hydraulic lifting cylinder and two sets of scissor frames 3 between the lifting platform 2 and the base platform 1, a tilting support platform 4 at the upper end of the lifting platform 2, a tilting connecting seat 5 rotatably mounted inside the tilting support platform 4, two tilting shafts on both sides of the tilting connecting seat 5, the two tilting shafts movably inserted into the tilting support platform 4 and fitted with tilting worm gears 27, and annular wheel rails 14 on the side of the tilting support platform 4 near the tilting connecting seat 5. Auxiliary guide wheels 15 are provided on one side of the annular wheel rail 14, and the auxiliary guide wheels 15 are movably inserted into the annular wheel rail 14. The lifting platform 2 is supported and connected by the scissor frame group 3 for vertical lifting. The lifting movement is controlled by the hydraulic lifting cylinder. When the lifting platform 2 is raised, the high position of the blasting face can be filled with explosives. The flipping worm gear 27 is connected with the servo stepper motor and the worm. The servo stepper motor drives the worm to rotate, and the worm controls the rotation of the flipping worm gear 27 to realize the rotation control of the flipping connecting seat 5. When the flip-connector 5 rotates, the flip-connector 5 is supported by two auxiliary guide wheels 15 within the annular wheel rail 14, thus maintaining the stability of the rotational support of the flip-connector 5.

[0021] One side of the flip-connecting seat 5 extends out of the flip-support platform 4 and has a first groove 11. One side of the flip-connecting seat 5 has a control plug 6. One side of the control plug 6 is movably inserted into the first groove 11. The side of the control plug 6 located in the first groove 11 has a second groove 12. A fine-tuning control cylinder 13 is located in the center of the first groove 11. One side of the fine-tuning control cylinder 13 is inserted into the second groove 12 and connected to the control plug 6. The control plug 6 and the flip-connecting seat 5 are movably connected. When the fine-tuning control cylinder 13 pushes the control plug 6 to move, the control plug 6 can move away from the flip-connecting seat 5 and the flip-support platform 4, and vice versa.

[0022] A support sleeve 7 is provided on one side of the control connector 6. A telescopic tube arm 8 is horizontally and movably inserted into the support sleeve 7. A tapered connector 10 is inserted into the side of the telescopic tube arm 8 that passes through the support sleeve 7 and is close to the blasting surface. Guide grooves 16 are provided on both sides of the telescopic tube arm 8 near the tapered connector 10. A guide bar 17 is horizontally provided on one side of the support sleeve 7. The guide bar 17 is inserted into the guide groove 16 on one side of the telescopic tube arm 8. The telescopic tube arm 8 and the support sleeve 7 of the control connector 6 are stably connected. Under the action of the guide bar 17 being inserted into the guide groove 16, the axial rotation of the telescopic tube arm 8 is prevented. At this time, in conjunction with the rotation of the flip-top connector 5 and the position adjustment of the control connector 6 and the flip-top connector 5, the telescopic tube arm 8 can be close to any filling hole of the blasting surface.

[0023] A gear groove is provided in the control connector 6, and a push gear 19 is rotatably provided in the gear groove. Several actuating tooth grooves 18 are provided in the guide groove 16 away from the guide bar 17 of the telescopic tube arm 8. One side of the push gear 19 is inserted into the guide groove 16 with actuating tooth grooves 18, and one side of the push gear 19 is meshed with the actuating tooth grooves 18. The push gear 19 is connected to the servo stepper motor. When the servo stepper motor drives the push gear 19 to rotate, the push gear 19 can move the telescopic tube arm 8 axially horizontally along the support sleeve 7 through the actuating tooth grooves 18. With the flipping of the flip connector 5 and the position movement of the control connector 6, the conical connector 10 can be aligned with the filling hole. Then the push gear 19 pushes the telescopic tube arm 8 close to the filling hole, and the conical surface of the conical connector 10 is inserted into the filling hole, completing the positioning of the telescopic tube arm 8 and the filling hole.

[0024] Two support blocks 20 are provided on one side of the telescopic arm 8. A control screw 21 is rotatably connected between the two support blocks 20 via a bearing. A sliding groove 22 is connected to the side of the telescopic arm 8 near the control screw 21. A pull slider 23 is sleeved on the control screw 21. One side of the pull slider 23 passes through the sliding groove 22 and is inserted into the telescopic arm 8. A supplementary push cylinder 24 is movably inserted into the side of the telescopic arm 8 away from the conical joint 10. The side of the pull slider 23 inserted into the telescopic arm 8 is fixedly connected to the supplementary push cylinder 24. One end of the telescopic rod of the supplementary push cylinder 24 has an extension... The long rod 25, which points to the tapered connector 10 and is equipped with a pusher plate 26, is used to control the rotation of the screw 21 by a servo motor when the telescopic arm 8 is filled with explosive tubes. This rotation pulls the slider 23 along the sliding groove 22 under the thread control of the screw 21, which in turn pulls the supplementary pusher cylinder 24 to move within the telescopic arm 8. Together with the extension rod 25 and the pusher plate 26, the explosive tubes are pushed into the filling hole. This operation eliminates the need for frequent disassembly and assembly of the high-altitude operation frame, improving the safety of construction and the efficiency of blasting and filling explosives, and enabling adaptive positioning and filling of explosives in multiple locations.

[0025] A discharge window 9 is provided on one side of the telescopic tube arm 8. The width of the discharge window 9 is greater than the diameter of the explosive and less than the inner diameter of the telescopic tube arm 8. The explosive is inserted into the telescopic tube arm 8 through the discharge window 9. Then, the explosive is inserted into the filling hole by pulling the slider 23 and pushing the supplementary push cylinder 24.
