Description

Technical Field

[0001] The invention belongs to the technical field of tunnel construction dust removal, and specifically refers to an energy-saving and environment-friendly tunnel dust removal device for civil engineering construction. Background Art

[0002] During the tunnel construction process, the excavation and blasting methods usually used will generate a large amount of dust. The dust is not only harmful to the human body, but also pollutes the construction environment, affects the construction line of sight, and brings inconvenience to the construction. The current method is to spray water mist to absorb dust, thereby preventing dust from flying, spraying water curtains to block dust, and setting up dust collectors for dust absorption; however, the above methods have certain disadvantages and limitations. The method of absorbing and blocking dust by water mist and water curtains can only be applied to situations with a small amount of dust. During the tunnel construction process, a large amount of dust will be generated, and large splashes and impacts will be generated. Not only can water mist and water curtains not effectively block them, but the impact force of dust and debris will also cause great damage to the dust collector, affecting the service life of the dust collector; and the current dust collector, whether it is fixed or vehicle-mounted, has a priority in the absorption range of dust. It is necessary to set up multiple devices, or manually adjust the position and angle to meet the use, and the dust removal effect is limited. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an energy-saving and environmentally friendly tunnel dust removal device for civil engineering construction. Compared with traditional dust removal devices, it has a larger dust removal range and better dust removal effect. It can also solve the problem of major damage to the dust collector and increase the service life of the dust removal equipment.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides an energy-saving and environment-friendly tunnel dust removal device for civil engineering construction, comprising:

[0005] Construction vehicles are used to travel in tunnels during construction, carrying dust removal equipment to remove dust;

[0006] A dust suction duct is used to timely remove dust generated during construction. The dust suction duct is a telescopic bellows, and a dust suction fan is arranged in the dust suction duct;

[0007] The adjustment mechanism is arranged on the construction vehicle and connected to the dust suction pipe, and is used to control the position of the dust suction pipe and increase the dust suction range of the dust suction pipe;

[0008] The energy-saving dust removal device is connected to the dust collection pipe, which introduces the dust sucked in by the dust collection pipe, filters it, and discharges fresh and pure air;

[0009] The spraying mechanism is used to spray water mist and water curtain, which has a certain limiting effect on dust.

[0010] Furthermore, the energy-saving dust removal device includes a dust removal box, a dust collecting box, a dust collector and a force transducer mechanism. The dust removal box is provided with an inlet channel, the inlet channel is horizontal and connected to the dust suction pipe, the dust removal box is provided with a turning channel, the turning channel is connected to the inlet channel and are arranged perpendicular to each other, the force transducer mechanism is arranged on one side of the turning channel to form an inner wall surface of the turning channel, the bottom of the turning channel is connected to the dust collecting box, the turning channel is also connected to the turning channel, the dust removal channel is connected to the side of the turning channel and is perpendicular to the turning channel, the dust collector is arranged in the dust removal box, the dust removal channel is connected to the dust collector, and the dust collector is provided with an exhaust channel.

[0011] When the dust is sucked into the introduction channel, the dust moves in a horizontal direction. Since the turning channel and the introduction channel are perpendicular to each other, the dust and airflow will directly hit the inner wall of the turning channel, that is, the position of the force transducer mechanism. At this time, the inertial impact force of the dust is offset, and then falls into the dust collecting box below the turning channel with gravity. The remaining part of the dust will also generate a certain amount of dust, and enter the dust collection duct with the airflow and enter the dust collector. At this time, the volume of dust entering becomes lower and the impact force becomes lower, which not only facilitates the dust removal of the dust collector, but also will not cause damage to the dust collector, thereby extending the service life and maintenance cycle of the dust collector. After dust removal by the dust collector, the clean air is discharged to the outside through the exhaust channel.

[0012] Furthermore, in order to prevent the dust that has fallen into the dust box from being raised again, an internal spraying assembly is provided in the dust removal box to spray the dust box so that the water and dust are combined to prevent the dust from being raised.

[0013] In order to prevent the dust in the dust box from being raised, in an embodiment, by increasing the distance between the dust collection duct and the dust collection box, it is possible to effectively prevent the dust from being raised from the dust collection box and entering the dust collection duct.

[0014] Further, the drag energy conversion mechanism includes a drag plate, a hydraulic shock absorber, a first oil pipeline, an accumulator, a second oil pipeline, a hydraulic motor and a power generation system. The drag plate is arranged on the inner wall of the steering channel to form an inner wall of the steering channel, and the position corresponds to the introduction channel. The hydraulic shock absorbers are provided in plurality and are evenly distributed and in contact with the drag plate. The drag plate is movably arranged. The accumulators are provided in plurality. The hydraulic shock absorber is connected to the accumulator through the first oil pipeline, the accumulator is connected to the oil inlet of the hydraulic motor through the second oil pipeline, the hydraulic motor is connected to the power generation system, and the power generation system includes a generator and a battery.

[0015] The oil discharge port of the hydraulic motor is connected to a return pipeline, and the return pipeline is connected to a hydraulic shock absorber.

[0016] The accumulator comprises an energy storage shell, an air bag, an air charging port, an oil inlet and an oil outlet, wherein the air charging port is connected to the air bag, the oil inlet is connected to a first oil pipeline, and the oil outlet is connected to a second oil pipeline.

[0017] When the drain plate is hit by the impact of dust, debris, and airflow, pressure is generated to squeeze the hydraulic shock absorber. The oil inside the hydraulic shock absorber flows to the accumulator through the first oil pipeline. The oil enters the accumulator and squeezes the airbag. The gas in the airbag is compressed and energy is stored in the form of hydraulic pressure. When energy is needed, the oil is released and enters the second oil pipeline from the oil outlet. The high-pressure oil enters the hydraulic motor. Due to the pressure difference, it acts on the plunger, gears, blades and other components inside the motor, causing these components to displace or rotate, generating driving force, which then acts on the power generation system to generate electricity for use and storage.

[0018] Furthermore, in order to ensure the normal and accurate operation of the oil, one-way valves are provided on the first oil pipeline, the second oil pipeline, the return pipeline, the oil inlet and the oil outlet.

[0019] Furthermore, the adjustment mechanism includes an adjustment box, a driving middle gear, a driven middle gear, a large gear, a small gear, a first rotating shaft, a second rotating shaft and a third rotating shaft, the driving middle gear is connected to the first rotating shaft, the driven middle gear is connected to the second rotating shaft, the driving middle gear and the driven middle gear are meshed with each other, the large gear is connected to the second rotating shaft, the small gear is connected to the third rotating shaft, the small gear and the large gear are meshed, the driving middle gear and the driven middle gear have the same number of teeth, the large gear has a larger number of teeth than the driving middle gear, the small gear has a smaller number of teeth than the driving middle gear, the third rotating shaft is the output shaft of the adjustment mechanism, a swing sleeve is provided on the dust collection pipe, and the third rotating shaft is connected to the swing sleeve.

[0020] The first rotating shaft is connected with a driving rod, and a swing cylinder is hingedly provided in the adjusting mechanism, and the output end of the swing cylinder is hingedly connected to the driving rod.

[0021] The swing cylinder is extended and retracted, thereby pushing the driving rod to rotate and swing, thereby driving the first rotating shaft to rotate, thereby driving the middle gear to drive the driven middle gear, the second rotating shaft, and the large gear to rotate, and then the large gear drives the small gear and the third rotating shaft to rotate. Due to the setting of the number of teeth of the driving middle gear, the driven middle gear, the large gear, and the small gear, the small gear is driven to rotate through the large gear, thereby increasing the speed limit, and then the speed and speed of the third rotating shaft are increased, thereby driving the swing range of the dust collection pipe to increase, thereby improving the range and effect of dust collection.

[0022] Furthermore, a lifting and lowering sleeve is provided on the dust suction pipe, a lifting and lowering cylinder is hingedly provided on the swing sleeve, and the telescopic end of the lifting and lowering cylinder is hingedly connected to the lifting and lowering sleeve.

[0023] Furthermore, the spraying mechanism comprises a water tank, a spraying pump and a spraying rack, the spraying rack is provided with a spraying head, the spraying rack is arranged close to the dust suction pipe, and the spraying pump pumps the water in the water tank to the spraying rack;

By setting up the introduction channel, the turning channel, the dust removal channel and the dust removal box, the inertia principle is utilized to release the impact force, and most of the dust and debris are collected and stored, and an energy-saving dust removal device is provided. The impact force of the airflow, dust and debris itself is utilized to convert mechanical energy into hydraulic energy, and then convert it into electrical energy again for equipment use and energy storage. It not only solves the problem that dust is difficult to remove and the problem of damage to the dust collector is solved, but also can achieve the effects of energy saving, production capacity and energy storage; by setting up the adjustment mechanism and utilizing the gear transmission ratio, the dust suction range of the dust suction pipe is expanded, and the dust suction effect is improved.

[0039] The technical solution adopted by the present invention is as follows: The present invention provides an energy-saving and environment-friendly tunnel dust removal device for civil engineering construction, comprising:

[0040] A construction vehicle 1 is used to travel in the tunnel during the construction process and carry a dust removal device to remove dust;

[0041] The dust suction pipe 2 is used to timely remove dust generated during construction. The dust suction pipe 2 is a telescopic bellows, and a dust suction fan is arranged in the dust suction pipe 2;

[0042] The adjustment mechanism 3 is provided on the construction vehicle 1 and connected to the dust suction pipe 2, and is used to control the position of the dust suction pipe 2 and increase the dust suction range of the dust suction pipe 2;

[0043] The energy-saving dust removal device 4 is connected to the dust collection pipe 2, introduces the dust sucked by the dust collection pipe 2, and discharges fresh and pure air after dust removal and filtration;

[0044] The spraying mechanism 5 is used to spray water mist and water curtain, which has a certain limiting effect on dust.

[0045] Furthermore, the energy-saving dust removal device 4 includes a dust removal box 6, a dust collecting box 7, a dust collector 8 and a force transducer mechanism 9. The dust removal box 6 is provided with an introduction channel 10, and the introduction channel 10 is horizontal and connected to the dust suction pipe 2. The dust removal box 6 is provided with a turning channel 11, and the turning channel 11 is connected to the introduction channel 10 and is arranged perpendicular to each other. The force transducer mechanism 9 is arranged on one side of the turning channel 11 to form an inner wall surface of the turning channel 11. The bottom of the turning channel 11 is connected to the dust collecting box 7. The turning channel 11 is also connected to a dust removal channel 13, and the dust removal channel 13 is connected to the side of the turning channel 11 and is perpendicular to the turning channel 11. The dust collector 8 is arranged in the dust removal box 6, and the dust removal channel 13 is connected to the dust collector 8. The dust collector 8 is provided with an exhaust channel 14.

[0046] When the dust is sucked into the introduction channel 10, the dust moves in a horizontal direction. Since the turning channel 11 and the introduction channel 10 are perpendicular to each other, the dust and airflow will directly hit the inner wall of the turning channel 11, that is, the position where the force transducer mechanism 9 is located. At this time, the inertial impact force of the dust is offset, and then falls into the dust collecting box 7 below the turning channel 11 with gravity. The remaining part of the dust will also generate a certain amount of dust, and enter the dust suction pipe 2 with the airflow, and enter the dust collector 8. At this time, the volume of the dust entering becomes lower and the impact force becomes lower, which not only facilitates the dust removal of the dust collector 8, but also does not cause damage to the dust collector 8, thereby extending the service life and maintenance cycle of the dust collector 8. After the dust is removed by the dust collector 8, the clean air is discharged to the outside through the exhaust channel 14.

[0047] Furthermore, in order to prevent the dust that has fallen into the dust box 7 from being raised again, an internal spraying assembly 15 is provided in the dust removal box body 6 to spray the dust box 7 so that the moisture and dust are combined to prevent the dust from being raised.

[0048] In order to prevent the dust in the dust box 7 from being raised, in the embodiment, by increasing the distance between the dust collection duct 2 and the dust box 7 , it is possible to effectively prevent the dust from being raised from the dust box 7 and entering the dust collection duct 2 .

The drag plate 16 is arranged on the inner wall of the steering channel 11 to form an inner wall of the steering channel 11, and the position corresponds to the introduction channel 10. There are multiple hydraulic shock absorbers 17, which are evenly distributed and contact the drag plate 16. The drag plate 16 is movably arranged. There are multiple accumulators 19. The hydraulic shock absorber 17 is connected to the accumulator 19 through the first oil pipeline 18. The accumulator 19 is connected to the oil inlet 24 of the hydraulic motor 21 through the second oil pipeline 20. The hydraulic motor 21 is connected to the power generation system 22, and the power generation system 22 includes a generator and a battery.

[0050] The oil discharge port 25 of the hydraulic motor 21 is connected to a return line 23 , and the return line 23 is connected to the hydraulic shock absorber 17 .

[0051] The accumulator 19 includes an energy storage shell 26, an air bag 27, an air charging port 28, an oil inlet 29 and an oil outlet 30, the air charging port 28 is connected to the air bag 27, the oil inlet 29 is connected to the first oil pipeline 18, and the oil outlet 30 is connected to the second oil pipeline 20.

[0052] When the drain plate 16 is impacted by the impact of dust, debris, and airflow, pressure is generated to squeeze the hydraulic shock absorber 17. The oil inside the hydraulic shock absorber 17 flows to the accumulator 19 through the first oil pipeline 18. The oil enters the accumulator 19 and squeezes the airbag 27. The gas in the airbag 27 is compressed, and energy is stored in the form of hydraulic pressure. When energy is needed, the oil is released, and the oil enters the second oil pipeline 20 from the oil outlet 30. The high-pressure oil enters the hydraulic motor 21. Due to the pressure difference, it acts on the plunger, gears, blades and other components inside the motor, causing these components to displace or rotate, generating driving force, and then acting on the power generation system 22 to generate electricity for use and storage.

[0053] Furthermore, in order to ensure the normal and accurate operation of the oil, one-way valves are provided on the first oil pipeline 18 , the second oil pipeline 20 , the return pipeline 23 , the oil inlet 29 and the oil outlet 30 .

[0054] Further, the adjustment mechanism 3 includes an adjustment box 31, a driving middle gear 32, a driven middle gear 33, a large gear 34, a small gear 35, a first rotating shaft 36, a second rotating shaft 37 and a third rotating shaft 38, the driving middle gear 32 is connected to the first rotating shaft 36, the driven middle gear 33 is connected to the second rotating shaft 37, the driving middle gear 32 and the driven middle gear 33 are meshed with each other, the large gear 34 is connected to the second rotating shaft 37, the small gear 35 is connected to the third rotating shaft 38, the small gear 35 is meshed with the large gear 34, the driving middle gear 32 and the driven middle gear 33 have the same number of teeth, the large gear 34 has a larger number of teeth than the driving middle gear 32, the small gear 35 has a smaller number of teeth than the driving middle gear 32, and the third rotating shaft 38 is the output shaft of the adjustment mechanism 3, and the dust collection pipe 2 is provided with a swing sleeve 41, and the third rotating shaft 38 is connected to the swing sleeve 41.

[0055] The first rotating shaft 36 is connected to a driving rod 39 . A swing cylinder 40 is hingedly provided inside the adjusting mechanism 3 . The output end of the swing cylinder 40 is hingedly connected to the driving rod 39 .

[0056] The swing cylinder 40 is extended and retracted, thereby pushing the driving rod 39 to rotate and swing, thereby driving the first rotating shaft 36 to rotate, thereby driving the middle gear 32 to drive the driven middle gear 33, the second rotating shaft 37, and the large gear 34 to rotate, and then the large gear 34 drives the small gear 35 and the third rotating shaft 38 to rotate. Due to the setting of the number of teeth of the driving middle gear 32, the driven middle gear 33, the large gear 34, and the small gear 35, the small gear 35 is driven to rotate through the large gear 34, thereby increasing the speed limit, and then the rotation speed and speed of the third rotating shaft 38 are increased, thereby driving the dust collection pipe 2 to increase the swing range, thereby improving the dust collection range and effect.

[0057] Furthermore, a lifting sleeve 42 is provided on the dust suction pipe 2 , a lifting cylinder 43 is hingedly provided on the swing sleeve 41 , and a telescopic end of the lifting cylinder 43 is hingedly connected to the lifting sleeve 42 .

[0058] Furthermore, the spraying mechanism 5 includes a water tank 44, a spraying pump 45 and a spraying rack 46, the spraying rack 46 is provided with a spraying head, the spraying rack 46 is arranged close to the dust suction pipe 2, and the spraying pump 45 pumps the water in the water tank 44 to the spraying rack 46;

[0059] In an embodiment, the spray rack 46 may be in the form of an atomizing spray or a water curtain.

[0060] In the embodiment, the width of the spraying frame 46 does not exceed the body of the construction vehicle 1 .

[0061] During specific use, the construction vehicle 1 can be moved to different positions for dust removal as the construction progresses. The swing cylinder 40 is started to drive the driving rod 39 to rotate and swing, thereby driving the first rotating shaft 36 to rotate, and then driving the middle gear 32 to drive the driven middle gear 33, the second rotating shaft 37, and the large gear 34 to rotate, and then the large gear 34 drives the small gear 35 and the third rotating shaft 38 to rotate, thereby driving the swing sleeve 41 and the dust suction pipe 2 to rotate, and increasing the swing range of the dust suction pipe 2; and starting the lifting and lowering cylinder 43 drives the lifting and lowering sleeve 42 to move up and down, thereby adjusting the pitch angle of the dust suction pipe 2, and then by adjusting the angle and position of the dust suction pipe 2, the dust suction range and dust suction effect are improved, and dust suction is simultaneously carried out through the spraying mechanism 5 to spray mist or water curtain.

[0062] After the dust is sucked in through the dust suction duct 2, the dust moves in a horizontal direction. Since the turning channel 11 and the introduction channel 10 are perpendicular to each other, the dust and the airflow will directly hit the pressure relief plate 16. At this time, the inertial impact force of the dust is offset, and then it falls into the dust collecting box 7 below the turning channel 11 with gravity. The remaining part of the dust will also generate a certain amount of dust, and enter the dust suction duct 2 with the airflow, and enter the dust collector 8. At this time, the volume of the dust entering becomes lower and the impact force becomes lower, which not only facilitates the dust removal of the dust collector 8, but also does not cause damage to the dust collector 8, thereby extending the service life and maintenance cycle of the dust collector 8. After the dust is removed by the dust collector 8, the clean air is discharged to the outside through the exhaust channel 14.

[0063] At the same time, when the drain plate 16 is impacted by the impact caused by dust, debris, and airflow, pressure is generated to squeeze the hydraulic shock absorber 17. The oil inside the hydraulic shock absorber 17 flows to the accumulator 19 through the first oil pipeline 18. The oil enters the accumulator 19 and squeezes the airbag 27. The gas in the airbag 27 is compressed, and the energy is stored in the form of hydraulic pressure. When energy is needed, the oil is released, and the oil enters the second oil pipeline 20 from the oil outlet 30. The high-pressure oil enters the hydraulic motor 21. Due to the pressure difference, it acts on the plunger, gears, blades and other components inside the motor, causing these components to displace or rotate, generating driving force, and then acting on the power generation system 22 to generate electricity for use and storage.
