Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering exploration technology, and in particular to a rotary multi-grooved rock grooving device. Background Technology

[0002] Tunnels are a major component of highway construction. Blasting is required during tunnel excavation, necessitating the drilling of blasting holes and the use of rock cutting equipment.

[0003] During the drilling and blasting of irregularly shaped holes, a large amount of dust is inevitably generated when drilling and grooving with drill bits. If this dust is directly dispersed into the air, it will not only seriously pollute the air quality but also pose a threat to the health of surrounding workers. Although the positions of existing blasting irregularly shaped holes can be marked in advance, the drill bit cannot be precisely moved and fine-tuned during actual operation, which brings great inconvenience to drilling and grooving rocks in different locations. Therefore, we designed a rotary multi-grooving tooth rock grooving device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a rotary multi-grooved rock grooving device.

[0018] 3. The rotation of the second threaded rod drives the belt and reciprocating screw to rotate, causing the moving plate and limit block to move back and forth, which continuously compresses or stretches the water tank. The water in the water tank is then sprayed out in the form of mist through multiple atomizing nozzles to suppress the dust generated during grooving, ensuring air quality and the health of surrounding workers.

[0019] In summary, the present invention, through the coordinated use of a height adjustment mechanism, an angle adjustment mechanism, and a moving mechanism, can adjust the drilling and slotting position to ensure precise drilling; the spraying mechanism can suppress the rock dust generated during drilling and slotting, thus ensuring air quality and the health of surrounding workers.

The outer wall of each sliding column 3 is fixedly connected with an anti-detachment block 8 that slides and connects to the inner wall of the hollow column 2. The cross-section of the anti-detachment block 8 is rectangular. The anti-detachment block 8 can limit the sliding column 3 to prevent it from detaching from the hollow column 2.

[0026] Two sliding columns 3 are fixedly connected to a U-shaped plate 9. An adjusting plate 10 is provided above the U-shaped plate 9. An angle adjustment mechanism is provided between the U-shaped plate 9 and the adjusting plate 10.

The grooving cutters 25 can perform grooving operations on the inner wall of the drilled hole. Multiple rock powder guide channels 26 are opened on the outer wall of the sleeve 24. The rock powder generated by grooving is discharged along the rock powder guide channels 26.

[0029] The adjusting plate 10 is equipped with a spraying mechanism, which includes a reciprocating screw 28 disposed above the adjusting plate 10. The outer wall of the second threaded rod 17 and the outer wall of the fixed plate 29 are together fitted with a belt 27. The outer wall of the second threaded rod 17 is fixedly connected to a driving wheel, and the outer wall of the reciprocating screw 28 is fixedly connected to a driven wheel. The belt 27 is fitted on the outer walls of the driving wheel and the driven wheel. The top of the adjusting plate 10 is fixedly connected to the fixed plate 29. One end of the reciprocating screw 28 is rotatably connected to the side wall of the fixed plate 29. The outer wall of the reciprocating screw 28 is fitted with a moving plate 30. The bottom of the moving plate 30 is fixedly connected to a limiting block 31. The top of the adjusting plate 10 is provided with a limiting groove 32. The limiting block 31 is inserted into the limiting groove 32 and slidably connected to its inner wall. The cooperation between the limiting block 31 and the limiting groove 32 can make the moving plate 30 reciprocate stably.

[0030] A water bladder 33 is fixedly connected to the outer wall of the fixed plate 29 and the outer wall of the movable plate 30. An inlet pipe 36 and an outlet pipe 38 are fixedly connected to the outer wall of the water bladder 33. The inlet pipe 36 passes through the fixed plate 29 and is fixedly connected to it. A first one-way valve 37 is fixedly connected to the outer wall of the inlet pipe 36, allowing water from the water tank 34 to be injected into the water bladder 33 only through the first connecting pipe 35. A second one-way valve 39 is fixedly connected to the outer wall of the outlet pipe 38, allowing water from the water bladder 33 to be discharged only through the second connecting pipe 40. (Base 1) A water tank 34 is fixedly connected to the top of the device. A first connecting pipe 35 is fixedly connected to the side wall of the water tank 34. The first connecting pipe 35 is fixedly connected to the inlet pipe 36. A second connecting pipe 40 is fixedly connected to the outlet pipe 38. A hollow pipe 41 is fixedly connected to the top of the regulating plate 10. The second connecting pipe 40 is fixedly connected to the side wall of the hollow pipe 41. A plurality of atomizing nozzles 42 distributed at equal intervals are fixedly connected to the top of the hollow pipe 41. Water is sprayed out in the form of mist through the atomizing nozzles 42 to suppress the rock powder dust generated during the grooving.

[0031] The bottom of the base 1 is equipped with four locking casters 44 arranged in a rectangular pattern to facilitate the movement of the device. A push rod 43 is fixedly connected to the side wall of the base 1. The outer wall of the push rod 43 is covered with a protective sleeve made of rubber to increase comfort.

[0032] In this invention, the operator can push the device to its destination by holding the push rod 43. At this time, the operator can rotate the handle 5, causing the double worm gear 4 to rotate, which in turn causes the two first worm wheels 6 and the first threaded rod 7 to rotate synchronously. This causes the anti-detachment block 8, sliding column 3, U-shaped plate 9, adjusting plate 10, push plate 18, drilling motor 20, transmission rod 21, and drill bit 22 to move up and down, adjusting the height of the rock grooving. The operator can also rotate the handle 14, causing the second worm gear 13, second worm wheel 12, rotating shaft 11, adjusting plate 10, push plate 18, drilling motor 20, transmission rod 21, and drill bit 22 to rotate around the rotating shaft 11, adjusting the angle of the rock grooving. During grooving, the drilling motor 20 is started, causing the transmission rod 21 and drill bit 22 to rotate. The drill bit 22 rotates to drill holes in the rock. During drilling, the propulsion motor 16 is started, driving the second worm gear 21 through its output end. The rotation of the threaded rod 17 moves the push plate 18, drilling motor 20, transmission rod 21, drill bit 22, fixing block 23, and sleeve 24, allowing grooving to be performed by the grooving cutter 25. The rock powder can be guided and discharged through the rock powder guide channel 26, thus realizing the grooving process of the rock. A large amount of dust is generated during drilling and grooving. The rotation of the second threaded rod 17 drives the belt 27 and reciprocating screw 28 to rotate, causing the moving plate 30 and the limiting block 31 to move back and forth, causing the water bag 33 to be continuously compressed or stretched. When the water bag 33 is stretched, the internal space of the water bag 33 increases, creating a negative pressure. Water in the water tank 34 is injected into the water bag 33 through the first connecting pipe 35. When the water bag 33 is compressed, the water inside is injected into the hollow pipe 41 through the second connecting pipe 40. Finally, the water is sprayed out in the form of mist through multiple atomizing nozzles 42 to suppress the dust generated during grooving, ensuring air quality and the health of surrounding workers.
