Description

Technical Field

[0001] The invention relates to the technical field of blasting dust removal, and in particular discloses auxiliary equipment for tunnel blasting construction. Background Art

[0002] Tunnel blasting refers to the process of drilling holes with gunpowder when excavating in a tunnel. After the tunnel blasting is completed, the gas generated by the explosion of the explosives contains a large amount of dust. Due to the small space and poor ventilation conditions of the tunnel, it is easy to pose a serious threat to the health and safety of construction workers and cause physical injuries to construction workers. Therefore, it is necessary to carry out dust reduction treatment on the tunnel after blasting. When the current dust reduction equipment uses water to reduce dust in the tunnel, the water consumption is large and cannot be recycled, resulting in low water utilization and poor practicality.

[0003] To solve the above problems, a Chinese patent with publication number CN220081497U discloses a tunnel blasting dust reduction device for blasting engineering. The device body includes a lifting mechanism, a water curtain mechanism and a water filtering mechanism. The lifting mechanism includes a lifting base, a lifting rod and an upper platform. The water curtain mechanism includes a water curtain frame and a water spray pipe arranged on the upper platform. The water curtain frame is composed of a plurality of water curtain rods. The water spray pipe is arranged on the water curtain rods, and a plurality of water spray ports are arranged on the water spray pipe. The water filtering mechanism includes a water guide plate, a water storage tank and a filter box. The dust reduction device of the utility model avoids the problem of the prior art that large-area water curtain spraying easily causes water mist to float in the air and water liquid to be lost through the design of the water curtain. The present embodiment recycles water as much as possible, improves water utilization, and reduces the pressure of tunnel water diversion.

[0004] The above-mentioned device has the following problems during actual use: the device uses a water curtain design to reduce dust dispersed in the tunnel, but due to the poor ventilation environment in the tunnel, the device cannot ventilate the tunnel in time, which leads to low air quality and low oxygen content in the tunnel, causing certain safety hazards for workers during construction; and the mixture of water and dust cannot be discharged from the tunnel in time, thereby reducing the visibility of the tunnel, and the practicality is poor. Summary of the invention

[0005] The invention provides an auxiliary device for tunnel blasting construction, so as to solve the problem that the existing dust reduction device cannot ventilate the tunnel when reducing dust in the tunnel.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an auxiliary equipment for tunnel blasting construction, including a support, a fixed pipe, a water supply mechanism for supplying water to the fixed pipe, and also including a dust reduction mechanism symmetrically arranged on both sides of the fixed pipe along the width direction of the fixed pipe; the dust reduction mechanism includes a conduit and a plurality of dust reduction components equidistantly arranged on the conduit along the length direction of the conduit; the conduit is connected with the fixed pipe; the dust reduction component includes a connecting pipe, a plurality of fan blades equidistantly arranged along the circumferential direction of the connecting pipe, a water inlet hole opened on the connecting pipe, a chamber opened in the fan blade, a plurality of side holes opened on both sides of the fan blade, and a driving part for driving the connecting pipe to rotate; the connecting pipe is rotatably connected to the conduit, and the water inlet hole is communicated with the conduit; the fan blade is fixedly connected to the connecting pipe; the chamber is communicated with the connecting pipe, and the side hole is communicated with the chamber.

[0007] The principles and advantages of this solution are:

[0008] 1. The connecting pipe is driven to rotate by the driving part, and the fan blades rotate synchronously during the rotation of the connecting pipe. The fan blades can ventilate the tunnel, thereby speeding up the air circulation in the tunnel, thereby improving the air quality in the tunnel, reducing the risks of subsequent workers in the tunnel, and protecting the lives and health of the workers.

[0009] 2. During the rotation of the fan blades, the fan blades have a certain centrifugal force, and then the fan blades can expand the scope of action of the liquid water when it is discharged from the side holes, enhance the effect of the liquid water, and make the liquid water form the first liquid water wall in the tunnel. Therefore, during the flow of air, it will first pass through the first liquid water wall to reduce dust, and then be discharged from the outside of the tunnel, thereby reducing the dust content in the air, reducing the pollution of dust to the environment and the harm to the workers.

[0010] Furthermore, the dust reduction component also includes an auxiliary pipe, a hose, an atomizing part symmetrically arranged on both sides of the conduit along the width direction of the conduit, and a power part for driving the auxiliary pipe to reciprocate along the length direction of the conduit; the auxiliary pipe is vertically slidably connected to the outer wall of the conduit; the two ends of the hose are respectively connected to the conduit and the auxiliary pipe; the atomizing part includes a side pipe, an atomizing pipe, a plurality of atomizing nozzles equidistantly arranged along the axial direction of the atomizing pipe, and a power unit for driving the atomizing pipe to rotate; the side pipe is connected to the auxiliary pipe; the atomizing pipe is rotatably connected to the side pipe, and the atomizing pipe is communicated with the side pipe; the atomizing nozzle is connected to the atomizing pipe.

[0011] When the water flows in the conduit, it will be discharged through the hose, auxiliary pipe, side pipe, and atomized water, and sprayed out under the action of the atomizing nozzle. The atomized water can contact the dust in the air more fully and comprehensively, thereby reducing the dust content in the air again and improving the dust reduction effect. In addition, during the spraying of water, the atomizing pipe is driven by the auxiliary pipe to make vertical reciprocating motion, thereby expanding the range of action of the atomizing pipe, so that the atomized water sprayed from the atomizing pipe can form an atomized water wall, thereby enhancing the effect of the atomized water and improving the efficiency of the atomized water.

[0012] Through the above movement, the air is dusted after passing through the first liquid water wall and then through the atomized water wall, ensuring that all dust in the air can be removed, further reducing the pollution of dust to the environment and the harm to workers.

[0013] Moreover, since the atomizing tube can also rotate, the atomizing tube has a certain centrifugal force, so the atomized water will further diffuse under the action of the centrifugal force, thereby increasing the area formed by the atomized water wall, so that the atomized water wall can contact the dust more fully and thoroughly, thereby enhancing the dust reduction effect of the atomized water wall, improving the dust reduction efficiency of the atomized water wall, and ensuring that the atomized water wall can comprehensively reduce the dust.

[0014] Furthermore, the atomization part also includes a linkage unit; the linkage unit includes a first guide block, a linkage block, and a linkage member used to drive the linkage block to reciprocate along the length direction of the first guide block; the first guide block is fixedly connected to the outer wall of the side tube; the linkage block is vertically slidably connected to the first guide block; a rubber tube is connected to the atomization nozzle, and the rubber tube is located on the movement trajectory of the linkage block.

[0015] During the spraying of the rubber hose, the linkage block hits the rubber hose, causing it to swing back and forth. The swing of the rubber hose changes the spray path of the atomized water, so that when the atomized water is discharged, the range of action will be further expanded, and the atomized water can be diffused over a large area. This means that the atomized water wall can perform a more thorough dust reduction treatment on the dust in the air, further enhancing the dust reduction effect and ensuring the dust reduction quality.

[0016] During the swinging of the rubber tube, the linkage block can also cause the rubber tube to deform. Therefore, through the deformation of the auxiliary tube, the water outlet diameter of the rubber tube can be changed, thereby increasing the pressure when the auxiliary tube discharges the atomized water, so that the atomized water can act at a longer distance and a wider range. Through the above movement, the atomized water can have a comprehensive and sufficient contact with the dust, which further improves the utilization rate of the atomized water.

[0017] Furthermore, it also includes a plurality of diffusion blocks which are equidistantly arranged along the length direction of the linkage block; the diffusion blocks are fixedly connected to the linkage block.

[0018] During the spraying of atomized water, the vertical reciprocating motion of the diffusion block enables the atomized water to further diffuse under the action of the diffusion block, thereby promoting a more complete contact between the atomized water and the dust, ensuring that more dust can be acted upon by the atomized water, comprehensively enhancing the effect of the atomized water, and thus improving the dust reduction quality of the atomized water.

[0019] Furthermore, it also includes an auxiliary part arranged on the side tube; the auxiliary part includes an auxiliary plate, a plurality of spray holes opened on the side tube, and a motion unit for driving the auxiliary plate to reciprocate along the length direction of the side tube; the auxiliary plate is slidably connected to the outer wall of the side tube, and the spray holes are located on the motion trajectory of the auxiliary plate.

[0020] Under the action of the spray hole, liquid water can be sprayed out through the spray hole and form a second liquid water wall. During the formation of the second liquid water wall, the dust in the air can be treated more carefully, and the amount of dust in the air can be reduced comprehensively. That is, through the dust treatment of the first liquid water wall, the atomized water wall, and the second liquid water wall in sequence, it is ensured that the dust in the air can be completely removed, and further ensured that the dust will not pollute the environment or cause harm to the human body.

[0021] Moreover, during the period of water spraying from the spray hole, the auxiliary plate makes reciprocating motion along the length direction of the side tube, so that the amount of water sprayed from the spray hole will gradually decrease, thereby increasing the pressure in the side tube, so that when the liquid water is sprayed out from the through hole, it can act at a farther distance, thereby increasing the range formed by the second liquid water wall, thereby further enhancing the dust reduction effect of the second liquid water wall on dust, and improving the dust reduction efficiency of the second liquid water wall on dust.

[0022] Furthermore, the auxiliary part also includes an auxiliary unit; the auxiliary unit includes a second guide block, a long plate, a mesh plate, and a power member for driving the long plate to reciprocate along the length direction of the second guide block; the second guide block is fixedly connected to the side tube; the long plate is vertically slidably connected to the second guide block; the mesh plate is fixedly connected to the long plate, and the spray hole is located on the movement trajectory of the mesh plate.

[0023] During the spraying of water from the spray hole, the vertical reciprocating motion of the mesh plate causes the water sprayed from the spray hole to be dispersed into several water droplets through the mesh plate, thereby expanding the scope of action of the liquid water and improving the utilization rate of the liquid water. That is, through the above motion, the scope of the second water wall is further expanded, ensuring that the dust can contact the second water wall more fully and thoroughly, and comprehensively enhancing the dust reduction effect of the second liquid water wall.

[0024] Furthermore, it also includes a boosting part arranged on the connecting pipe; the boosting part includes an annular hollow tube, an air inlet hole opened on the connecting pipe, an air exhaust hole opened on the annular hollow tube, and a boosting unit symmetrically arranged on both sides of the connecting pipe along the axial direction of the connecting pipe; the annular hollow tube is fixedly connected to the outer wall of the conduit, the annular hollow tube is in contact with the connecting pipe, and the air inlet hole is communicated with the air exhaust hole; the boosting unit includes a piston cylinder, a piston block, and a first spring; the piston cylinder is fixedly connected to the outer wall of the conduit; the piston block is vertically slidably connected to the piston cylinder, and the piston block is located on the movement trajectory of the side tube; the two ends of the first spring are respectively connected to the piston block and the piston cylinder; the piston cylinder is connected with an air inlet pipe and an exhaust pipe; the free end of the air inlet pipe is connected to the conduit, and the free end of the exhaust pipe is connected to the annular hollow tube.

[0025] Through the mutual cooperation between the piston block and the piston cylinder, the piston cylinder can pressurize the liquid water flowing in the conduit, and then when the liquid water is discharged from the conduit, the force of the water discharge can be increased, so that the liquid water can act at a longer distance and a wider range, further enhancing the dust reduction effect of the first liquid water wall, the atomized water wall, and the second liquid water wall.

[0026] Furthermore, it also includes a driving unit symmetrically arranged on both sides of the fixed tube along the width direction of the fixed tube; the driving unit includes a connecting plate, a driving shaft, a plurality of first bevel gears equidistantly arranged along the axial direction of the driving shaft, and a driving member for driving the driving shaft to rotate; the connecting plate is fixedly connected to the fixed tube; the driving shaft is rotatably connected to the connecting plate; the first bevel gear is fixedly connected to the driving shaft; the driving part is a second bevel gear; the second bevel gear is fixedly connected to the connecting tube, and the first bevel gear is meshed with the second bevel gear.

[0027] During the rotation of the driving shaft, the first bevel gear is meshed with the second bevel gear, thereby driving the second bevel gear to rotate. When the second bevel gear rotates, the connecting pipe rotates synchronously.

[0028] Furthermore, the power unit includes a first cam and a second spring; the first cam is fixedly connected to the connecting pipe, and the first cam abuts against the auxiliary pipe; and both ends of the second spring are respectively connected to the auxiliary pipe and the guide tube.

[0029] During the rotation of the connecting pipe, the first cam rotates synchronously. During the rotation of the first cam, when the raised portion of the first cam abuts against the auxiliary pipe, the auxiliary pipe moves vertically upward, and the second spring is compressed; when the raised portion of the first cam no longer abuts against the auxiliary pipe, the auxiliary pipe is reset under the action of the second spring, and the auxiliary pipe moves vertically downward. Therefore, the auxiliary pipe can perform vertical reciprocating motion.

[0030] Furthermore, the power unit comprises a first rack and a first gear; the first rack is fixedly connected to the outer wall of the conduit; the first gear is fixedly connected to the atomization tube, and the first gear is meshed with the first rack.

[0031] When the atomizer tube makes vertical reciprocating motion with the auxiliary tube, the first gear rotates through the meshing of the first gear and the first rack. When the first gear rotates, the atomizer tube rotates synchronously. Therefore, when the atomizer tube makes vertical reciprocating motion, the atomizer tube can also rotate.

[0055] Specific implementation process:

[0056] The support 1 is set in the tunnel, and water is then injected into the water pipe 3 through a water pump, so that the water can flow through the fixed pipe 2 and into the conduit 4. While the water is flowing in the conduit 4, the motor 33 is started, and the drive shaft 30 is driven to rotate through the output shaft of the motor 33. During the rotation of the drive shaft 30, the connecting pipe 5 is driven to rotate through the meshing of the first bevel gear 31 and the second bevel gear 34. During the rotation of the connecting pipe 5, the fan blade 6 rotates synchronously.

[0057] During the rotation of the fan blades 6, the water in the duct 4 will be sprayed out to the side hole 7 through the connecting pipe 5, thereby achieving dust reduction treatment for the dust in the air during the air flow, thereby reducing the amount of dust in the air, reducing the pollution of dust to the environment and the harm to the human body.

[0058] Furthermore, during the rotation of the fan blades 6, the fan blades 6 have a certain centrifugal force, and thus the fan blades 6 can expand the scope of action of the liquid water when it is discharged from the side holes 7, enhance the effect of the liquid water, and form the first liquid water wall in the tunnel. Therefore, during the flow of air, the air will first pass through the first liquid water wall for dust reduction, and then be discharged from the outside of the tunnel, thereby enhancing the dust reduction effect of the liquid water on the dust in the air and improving the dust reduction efficiency of the liquid water.

[0059] During the rotation of the connecting pipe 5, the first cam 35 rotates synchronously. During the rotation of the first cam 35, when the protrusion of the first cam 35 abuts against the auxiliary pipe 8, the auxiliary pipe 8 moves vertically upward, and the second spring 49 is compressed; when the protrusion of the first cam 35 no longer abuts against the auxiliary pipe 8, the auxiliary pipe 8 is reset under the action of the second spring 49, and the auxiliary pipe 8 moves vertically downward. Therefore, the auxiliary pipe 8 can perform vertical reciprocating motion.

[0060] Through the above movement, the water will be discharged through the hose 9, the auxiliary pipe 8, the side pipe 10, and the atomizing pipe 11 while flowing in the conduit 4, and the atomized water will be sprayed out under the action of the atomizing nozzle 12, and the atomized water can contact the dust in the air more fully and comprehensively, thereby reducing the dust content in the air again and improving the dust reduction effect on the dust. In addition, during the water spraying period, the atomizing pipe 11 is driven by the auxiliary pipe 8 to make vertical reciprocating motion, thereby expanding the scope of action of the atomizing pipe 11, so that the atomized water sprayed from the atomizing pipe 11 can form an atomized water wall, thereby enhancing the effect of the atomized water and improving the efficiency of the atomized water.

[0061] That is, after the air passes through the first liquid water wall for dust reduction, it passes through the atomized water wall for dust reduction again, ensuring that all dust in the air can be removed, further reducing the pollution of dust to the environment and the harm to workers.

[0062] When the atomizing tube 11 makes vertical reciprocating motion with the auxiliary tube 8, the first gear 37 is meshed with the first rack 36, and then the first gear 37 rotates. When the first gear 37 rotates, the atomizing tube 11 rotates synchronously. Therefore, when the atomizing tube 11 makes vertical reciprocating motion, the atomizing tube 11 can also rotate.

[0063] Through the above movement, since the atomizing tube 11 can also rotate, the atomizing tube 11 has a certain centrifugal force, so the atomized water will further diffuse under the action of the centrifugal force, thereby increasing the area formed by the atomized water wall, so that the atomized water wall can contact the dust more fully and thoroughly, thereby enhancing the dust reduction effect of the atomized water wall, improving the dust reduction efficiency of the atomized water wall, and ensuring that the atomized water wall can comprehensively reduce the dust.

[0064] When the rubber tube 16 rotates with the atomizer tube 11, the first gear 37 and the second gear 40 mesh, thereby driving the short shaft 39 to rotate. When the short shaft 39 rotates, the second cam 41 rotates synchronously. When the second cam 41 rotates, when the protrusion of the second cam 41 abuts against the linkage block 15, the linkage block 15 moves vertically upward, and the third spring stretches; when the protrusion of the second cam 41 no longer abuts against the linkage block 15, the linkage block 15 is reset under the action of the third spring, and the linkage block 15 moves vertically downward. Therefore, the linkage block 15 can perform vertical reciprocating motion.

[0065] During the vertical reciprocating motion of the linkage block 15, the linkage block 15 impacts the rubber tube 16, thereby causing the rubber tube 16 to swing back and forth. The swing of the rubber tube 16 changes the spray path of the atomized water, so that when the atomized water is discharged, the range of action is further expanded, and the atomized water can be diffused over a large area. That is, the atomized water wall can perform a more thorough dust reduction treatment on the dust in the air, further enhancing the dust reduction effect and ensuring the dust reduction quality.

[0066] During the swinging of the rubber tube 16, the linkage block 15 can also cause the rubber tube 16 to deform. Therefore, through the deformation of the auxiliary tube 8, the diameter of the water outlet pipe 3 of the rubber tube 16 can be changed, thereby increasing the pressure when the auxiliary tube 8 discharges the atomized water, so that the atomized water can act at a longer distance and a wider range. Through the above movement, the atomized water can be fully and fully in contact with the dust, that is, the utilization rate of the atomized water is further improved.

[0067] During the spraying of atomized water, the diffusion block 17 moves synchronously with the linkage block 15, so that the atomized water can be further diffused under the action of the diffusion block 17, thereby promoting a more complete contact between the atomized water and the dust, ensuring that more dust can be acted upon by the atomized water, comprehensively enhancing the effect of the atomized water, and thus improving the dust reduction quality of the atomized water.

[0068] While the water is flowing in the side pipe 10, liquid water can be sprayed out through the spray hole 19 under the action of the spray hole 19 and form a second liquid water wall. During the formation of the second liquid water wall, dust in the air can be treated with more detailed dust reduction, and the amount of dust in the air is comprehensively reduced. That is, by the first liquid water wall, the atomized water wall, and the second liquid water wall successively performing dust reduction treatment on the dust, it is ensured that the dust in the air can be completely removed, and it is further ensured that the dust will not pollute the environment or cause harm to the human body.

[0069] During the rotation of the short shaft 39, the screw rod 42 rotates synchronously. During the rotation of the screw rod 42, the nut seat 44 can reciprocate along the length direction of the guide rod 43. During the movement of the nut seat 44, the auxiliary plate 18 moves synchronously.

[0070] Through the above-mentioned movement, while the liquid water is sprayed from the spray hole 19, it reciprocates along the length direction of the side tube 10 through the auxiliary plate 18, so that the amount of water sprayed from the spray hole 19 will gradually decrease, thereby increasing the pressure in the side tube 10, so that when the liquid water is sprayed out from the through hole, the distance it can act is farther, thereby increasing the range of the second liquid water wall, thereby further enhancing the dust reduction effect of the second liquid water wall on dust, and improving the dust reduction efficiency of the second liquid water wall on dust.

[0071] During the movement of the auxiliary plate 18, the second rack 45 moves synchronously. During the movement of the second rack 45, the third gear 47 rotates through the meshing of the second rack 45 and the third gear 47. During the rotation of the third gear 47, the rotating shaft 46 rotates synchronously. During the rotation of the rotating shaft 46, the third cam 48 rotates synchronously.

[0072] During the rotation of the third cam 48, when the protrusion of the third cam 48 abuts against the long board 21, the long board 21 moves vertically downward, and the fourth spring is compressed; when the protrusion of the third cam 48 no longer abuts against the long board 21, the long board 21 is reset under the action of the fourth spring, and the long board 21 moves vertically upward. Therefore, the long board 21 can perform vertical reciprocating motion.

[0073] During the movement of the long board 21, the mesh plate 22 moves synchronously. Through the vertical reciprocating movement of the mesh plate 22, the water sprayed from the spray hole 19 is dispersed into a plurality of water droplets through the mesh plate 22, thereby expanding the scope of action of the liquid water and improving the utilization rate of the liquid water. That is, through the above movement, the scope of the second water wall is further expanded, ensuring that the dust can contact the second water wall more fully and thoroughly, and comprehensively enhancing the dust reduction effect of the second liquid water wall.

[0074] During the vertical reciprocating motion of the side pipe 10, the side pipe 10 can drive the piston block 25 to perform vertical reciprocating motion with the cooperation of the first spring 26. During the vertical reciprocating motion of the piston block 25, the piston cylinder 24 can pressurize the liquid water flowing in the conduit 4 with the cooperation of the piston block 25 and the piston cylinder 24, and then when the liquid water is discharged from the conduit 4, the force of the water discharge can be increased, so that the liquid water can act at a longer distance and a wider range, further enhancing the dust reduction effect of the first liquid water wall, the atomized water wall, and the second liquid water wall.
