Description

Technical Field

[0001] The invention relates to the technical field of drilling and blasting, and in particular to a blasting drilling device for blasting construction. Background Art

[0002] Blasting construction is a common method in civil engineering and mining engineering, used to break rocks, concrete or other hard materials. Its construction steps include: drilling, pre-burying explosives and starting blasting. For the drilling step, it is necessary to ensure the quality of the drilling, maintain the verticality of the drilling, the consistency of the hole diameter and the integrity of the drilling wall to avoid the collapse of the hole wall. Drilling rigs are often used for drilling.

[0003] There are many types of drilling rigs on the market. Such drilling rigs use a rotary propulsion drilling method to drill holes in the soil layer. Among them, the announcement number CN105874151A discloses a drilling rig, which includes a frame and a pair of piston rods arranged laterally spaced relative to each other. The pair of piston rods are configured to extend and retract relative to the frame along the axial direction. The drilling rig includes a slide unit mounted on the frame. The slide unit includes a pair of sliders spaced laterally relative to each other. Each slider in the pair of sliders includes an axial channel arranged therein. The slide unit includes a support member slidably arranged in each of the axial channels; Although this drilling rig has the advantage of automatically performing the lifting and lowering of the drilling rig components, it still has the following shortcomings: when the drill bit on the drilling rig rotates, it will produce a compressive force on the rock and soil, and the rock and soil will produce a reaction force on the drill bit. The magnitude of this force is related to the hardness of the rock and soil. The speed of the motor that drives the drill bit to rotate is fixed, and the pressure of the hydraulic rod is fixed. Therefore, when the hardness of the rock and soil changes, the reaction force will change, affecting the drilling of the drill bit; some rock and soil drilling requires water injection equipment, and an additional pump is used to inject external water into the borehole to soak and soften the rock and soil in the borehole. Since water injection requires an additional pump power system, the energy consumption is large, and the water injection amount cannot be adjusted according to the hardness of the rock and soil. There are certain limitations in its use.

[0027] A transmission mechanism is installed between the rotating shaft 22 and the drill bit 6; the transmission mechanism is used to drive the drill bit 6 to rotate, and has the advantages of speed transmission and reduced energy loss; the transmission mechanism includes a bevel gear 1 23 fixedly installed on the rotating shaft 22, a support rod is rotatably installed on the protection box 8, a bevel gear 2 24 meshing with the bevel gear 1 23 is fixedly installed on the support rod, a gear 2 25 is fixedly installed on the support rod, a gear 18 meshing with the gear 2 25 is rotatably installed on the protection box 8, two limit blocks are fixedly installed on the gear 18, and two limit slots 21 slidably connected to the corresponding limit blocks are provided on the drill bit 6; The rotation of the rotating shaft 22 drives the bevel gear 1 23 to rotate, the rotation of the bevel gear 1 23 drives the bevel gear 2 24 meshing therewith to rotate, the rotation of the bevel gear 2 24 drives the support rod to rotate, thereby driving the gear 2 25 to rotate, the rotation of the gear 2 25 drives the gear 1 18 to rotate, thereby driving the drill bit 6 to rotate; the function of the limit block and the limit groove 21 is to ensure that the gear 1 18 can drive the drill bit 6 to rotate, and the rotation of the drill bit 6 does not affect the advancement of the drill bit 6.

[0028] Embodiment 3: This embodiment is different from the technical solution of Embodiment 2 in that: Figure 1-Figure 3 , Figure 8 , energy absorbing part, the energy absorbing part is installed on the hydraulic rod 4, and is used to absorb the kinetic energy of the vibration generated by the operation of the drill bit 6. The energy absorbing part includes an energy absorbing cylinder 11 and an energy absorbing cylinder 2 12 fixedly installed on the hydraulic rod 4. The energy absorbing cylinder 1 1 and the energy absorbing cylinder 2 12 are both installed with a conducting mechanism that matches the drill bit 6; This part can absorb and utilize the kinetic energy caused by vibration due to the different hardness of rock and soil, and use the absorbed energy to drive the operation of the internal structure without the need for an additional driving source, thereby improving energy utilization and reducing energy consumption.

[0029] The transmission mechanism includes a plurality of baffles 27 fixedly installed inside the energy absorbing cylinder 11 and the energy absorbing cylinder 12, and the plurality of baffles 27 cooperate with each other. A plurality of slide bars are slidably installed through the energy absorbing cylinder 11 and the energy absorbing cylinder 12, and a piston plate 28 matching with the corresponding two baffles 27 is fixedly installed on each slide bar. A spring 29 is fixedly installed between each piston plate 28 and the corresponding energy absorbing cylinder 11 and the energy absorbing cylinder 12, and a touch plate 30 matching with the drill bit 6 is fixedly installed on the end of each slide bar away from the corresponding piston plate 28; When the drill bit 6 encounters rocks and soils of different hardness during operation, it will generate vibrations, which will cause the drill bit 6 to move left and right. At this time, the drill bit 6 will press the touch plate 30, and drive the slide rod and the piston plate 28 to move between the two baffles 27 through the touch plate 30, so as to compress the air between the two baffles 27, thereby converting the kinetic energy of the vibration into the pressure internal energy of the air, realizing energy conversion; this part can convert and utilize the vibration kinetic energy generated by the drill bit 6, realize the utilization of waste energy, and reduce energy loss.

[0030] In a further embodiment, referring to Figure 6-Figure 7 , Fig. 9 , the speed regulating part is installed between the energy absorbing cylinder 11 and the rotating shaft 22, and is used to adjust the speed of the rotating shaft 22. The speed regulating part includes a hollow speed reducing disc 10 fixedly installed on the protection box 8. The energy absorbing cylinder 12 and the speed reducing disc 10 are connected through the air pipe 14. A plurality of baffles 31 matched in pairs are fixedly installed in the speed reducing disc 10. A speed regulating mechanism matched with the rotating shaft 22 is installed on the speed reducing disc 10; By converting the kinetic energy of vibration into the pressure internal energy of air as described above, energy conversion is achieved. The generated air pressure internal energy, under the action of which, will compress the air in the energy absorption cylinder 12 into the air storage ring 15 and then be transported to the speed reduction plate 10 through the air pipe 14.

[0031] The speed regulating mechanism includes baffle plates 31 fixedly mounted inside the speed reduction plate 10 and matched with each other in pairs, a piston plate 32 is slidably mounted between the two matched baffle plates 31, a friction plate 33 matched with the rotating shaft 22 is fixedly mounted on each piston plate 32, the friction plate 33 penetrates and extends out of the speed reduction plate 10, and a reset structure is installed between each piston plate 32 and the corresponding baffle plate 31; The function of the speed regulating mechanism is to automatically adjust the rotation speed of the shaft 22 according to the hardness of the rock and soil, reduce the rotation speed of the drill bit during drilling, reduce the vibration amplitude of the drill bit during drilling, and thus protect the drill bit and ensure stable operation of the drill bit.

[0032] As air is input, the air in the reduction plate 10 increases, and the pressure increases, which will press the second piston plate 32 to move, and then the friction plate 33 is driven to move through the second piston plate 32, so that the friction plate 33 and the rotating shaft 22 are pressed against each other.

[0033] Due to the pressure of the friction plate 33, the rotating shaft 22 will be subjected to a reverse resistance, preventing the rotating shaft 22 from rotating. When the driving force of the motor 7 is fixed, the resistance increases, the rotation speed of the rotating shaft 22 will decrease accordingly, and the rotation speed of the driving end of the motor 7 will also decrease. Reducing the rotation speed can slow down the rotation speed of the drill bit 6, thereby achieving the purpose of reducing the vibration amplitude. This part can automatically adjust the rotation speed of the driving end of the motor 7 according to the hardness of the rock and soil, reduce the rotation speed of the drill bit 6 during drilling, thereby reducing the vibration amplitude of the drill bit 6 during drilling, and then protect the drill bit 6 to ensure stable operation of the drill bit 6.

[0034] The reset structure includes a fixed plate 34 fixedly mounted on the baffle plate 31, and a plurality of springs 35 are fixedly mounted between the fixed plate 34 and the piston plate 32; the reset structure is used to reset the piston plate 32, and has the benefit of automatic return and repeated use.

[0035] A hole is provided on the reduction disc 10 for exhausting air, and the size of the hole is designed to ensure that the exhaust volume is smaller than the intake volume, so as to achieve the purpose of inflation; the spring 2 35 can reset the piston plate 2 32 after the vibration of the drill bit 6 becomes smooth, and at this time, the air in the reduction disc 10 will be discharged through the hole, so as to keep the reduction disc 10 in the initial pressure state.

[0036] Embodiment 4: This embodiment is different from the technical solution of embodiment 3 in that: Figure 3 , Figure 6-Figure 7 , unloading part, the unloading part is installed between the speed reduction disc 10 and the top plate 9, and is used to adjust the propulsion force of the hydraulic rod 4. The unloading part includes a cylinder 37 fixedly installed on the protection box 8, a slider is fixedly installed on the driving end of the cylinder 37, a friction ring 17 is fixedly installed on the slider, and a resistance mechanism matched with the friction ring 17 is installed on the top plate 9. The cylinder 37 is connected to the speed reduction disc 10 through a conduit 38; the function of the resistance mechanism is to apply resistance to the hydraulic rod 4, reduce the propulsion speed of the hydraulic rod 4, and has the advantage of adjusting the propulsion speed of the hydraulic rod 4 to control the drilling speed.

[0037] As the pressure in the speed reduction plate 10 increases, part of the air will enter the cylinder 37 through the conduit 38, causing the driving end of the cylinder 37 to extend. At this time, the cylinder 37 will drive the friction ring 17 to move (the friction ring 17 is made of rubber material), and cooperate with the resistance mechanism to apply resistance to the hydraulic rod 4, thereby reducing the propulsion speed of the hydraulic rod 4; This part can automatically adjust the propulsion force of the hydraulic rod 4 according to the hardness of the rock and soil, thereby reducing the propulsion speed of the drill bit 6 during drilling, reducing the vibration amplitude of the drill bit 6 during drilling, and then protecting the drill bit 6 and making the operation of the drill bit 6 more stable.

[0038] The resistance mechanism includes a toothed plate 13 fixedly mounted on the top plate 9, a rotating column rotatably mounted on the protection box 8, a first gear 26 meshing with the toothed plate 13 fixedly mounted on the rotating column, and a friction roller 36 matched with the friction ring 17 fixedly mounted on the rotating column; When the cylinder 37 pushes the friction ring 17 to move, the pressing force between the friction ring 17 and the friction roller 36 will increase, thereby increasing the friction between the friction ring 17 and the friction roller 36. The increase in friction will prevent the first gear 26 from rotating, thereby applying a resistance to the tooth plate 13 to prevent the tooth plate 13 from moving. The resistance will directly act on the hydraulic rod 4. When the thrust of the hydraulic rod 4 remains unchanged, the resistance to the hydraulic rod 4 will increase, and the propulsion speed of the hydraulic rod 4 will slow down, thereby achieving the purpose of shock absorption.

[0039] The friction roller 36 is made of the same rubber material as the friction ring 17 (the friction roller 36 is made of a metal or non-metallic non-deformable material, and the friction force between the friction roller 36 and the friction ring 17 is less than the friction force when the friction roller 36 is made of rubber), which can maximize the friction resistance. The friction resistance increases significantly, and the advancement speed of the hydraulic rod 4 is significantly slowed down.

At this time, the air will pass through the sealing column 46 and enter the water injection ring 16. Under the action of the second spring 48, the sealing disk 49 will be reset to prevent the air injected into the water injection ring 16 from flowing back. A water tank 5 is fixedly installed on the protection box 8. The water tank 5 is connected to the water injection ring 16 through the water injection pipe 40. A water injection mechanism is installed in the water injection ring 16.

As the annular push plate 42 moves, the water on the annular push plate 42 will be sprayed onto the drill bit 6 through the water outlet pipe 41, so as to cool the drill bit 6 or moisten the rock and soil.

[0043] This part can automatically add an appropriate amount of water into the borehole according to the hardness of different rock and soil types, which is used for rock and soil drilling, making the rock and soil drilling more stable. At the same time, it does not require an additional pump power system and has better energy saving performance.

At this time, the annular push plate 42 is reset under the action of the first spring 43; the function of this part is to adjust the pressure in the water injection ring 16 to achieve the purpose of intermittent water injection.

[0045] The specific operation steps of the blasting drilling device for blasting construction are as follows: Drill bit advancement: The operation of the hydraulic rod 4 will drive the drill bit 6 to rise and fall through the top plate 9, thereby achieving advancement of the drill bit 6; Rotation of the drill bit: the driving end of the motor 7 rotates to drive the roller to rotate, and the roller drives the roller 20 to rotate through the crawler 19, thereby driving the rotating shaft 22 to rotate, the rotation of the rotating shaft 22 drives the bevel gear 1 23 to rotate, the rotation of the bevel gear 1 23 drives the bevel gear 2 24 meshing therewith to rotate, the rotation of the bevel gear 2 24 drives the support rod to rotate, thereby driving the gear 2 25 to rotate, the rotation of the gear 2 25 drives the gear 1 18 to rotate, thereby driving the drill bit 6 to rotate, thereby realizing the drilling of the drill bit 6.

[0046] Energy absorption: When the drill bit 6 encounters rocks and soils of different hardness during operation, it will generate vibrations, which will cause the drill bit 6 to move left and right. At this time, the drill bit 6 will press the touch plate 30, and the touch plate 30 will drive the slide rod and the piston plate 1 28 to move between the two baffles 1 27, so as to compress the air between the two baffles 1 27; Slowing down the rotation speed of the drill bit 6: the air pressure internal energy generated by the compressed air will compress the air in the energy absorbing cylinder 12 into the air storage ring 15, and then be transported to the deceleration plate 10 through the air pipe 14. With the input of air, the air in the deceleration plate 10 increases, which will press the piston plate 32 to move, and then the friction plate 33 is driven to move through the piston plate 32, so that the friction plate 33 and the rotating shaft 22 are pressed against each other; Due to the pressure of the friction plate 33, the rotating shaft 22 will be subjected to a reverse resistance, preventing the rotating shaft 22 from rotating. When the driving force of the motor 7 is fixed, the resistance increases, the rotation speed of the rotating shaft 22 will decrease accordingly, and the rotation speed of the driving end of the motor 7 will also decrease. Reducing the rotation speed can slow down the rotation speed of the drill bit 6, thereby achieving the purpose of reducing the vibration amplitude. Slow down the speed of the drill bit 6: as the pressure in the speed reduction plate 10 increases, part of the air will enter the cylinder 37 through the conduit 38, causing the driving end of the cylinder 37 to extend. At this time, the cylinder 37 will drive the friction ring 17 to move (the friction ring 17 is made of rubber material), and cooperate with the resistance mechanism to apply resistance to the hydraulic rod 4, thereby reducing the propulsion speed of the hydraulic rod 4; When the cylinder 37 pushes the friction ring 17 to move, the pressing force between the friction ring 17 and the friction roller 36 will increase, thereby increasing the friction between the friction ring 17 and the friction roller 36. The increase in friction will prevent the first gear 26 from rotating, thereby applying a resistance to the tooth plate 13 to prevent the tooth plate 13 from moving. The resistance will directly act on the hydraulic rod 4. When the thrust of the hydraulic rod 4 remains unchanged, the resistance to the hydraulic rod 4 will increase, and the propulsion speed of the hydraulic rod 4 will slow down, thereby achieving the purpose of shock absorption.

[0047] The drill bit 6 is injected with water for cooling and the soil layer is softened: the water in the water tank 5 flows into the water injection ring 16 through the water injection pipe 40 by the gravity of the water itself; The water flowing into the water injection ring 16 will stay on the upper part of the annular push plate 42, and the air in the energy absorbing cylinder 11 will be pressed into the water injection ring 16 through the energy absorbing cylinder 11, so that the pressure at the bottom of the annular push plate 42 in the water injection ring 16 will increase, and the annular push plate 42 will be pushed to move. As the annular push plate 42 moves, the water on the annular push plate 42 will be sprayed onto the drill bit 6 through the water outlet pipe 41, so as to cool the drill bit 6 or moisten the rock and soil. When the bottom of the annular push plate 42 moves up to the position of the vent pipe 44, the vent pipe 44 loses the obstruction of the annular push plate 42. At this time, the air under the annular push plate 42 will be discharged through the vent pipe 44. At this time, the annular push plate 42 is reset under the action of the first spring 43 to achieve the purpose of intermittent water injection.
