Description

Technical Field

[0001] This invention relates to the field of dust collection device technology, specifically a dust collection device for subway construction. Background Technology

[0002] During subway construction, both open-cut and tunneling methods generate a large amount of dust. This dust not only pollutes the environment and harms the health of construction workers, but may also affect the lives of nearby residents. It also causes wear and tear on construction equipment, reducing its service life. Furthermore, subway tunnels are enclosed and narrow with poor ventilation, making it easy for dust to accumulate. Currently, dust control in subway construction mainly relies on methods such as mist cannons, sprinkler systems, and air curtains.

[0003] Traditional dust collection devices cannot simultaneously absorb dust floating in the air and dust deposited on the ground, and they are difficult to adapt to the complex and ever-changing construction environment inside tunnels. Summary of the Invention

[0004] The purpose of this invention is to provide a dust collection device for subway construction to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The subway construction dust collection device includes a body, within which a filter, a suction device, and a water supply tank are installed. A dust collection drive assembly is disposed within the body, and the actuator of the dust collection drive assembly is equipped with a floating dust suction head and a dust accumulation suction head, both of which are connected to the filter via pipes. A dust detector is mounted on the top of the floating dust suction head. An atomizing nozzle is rotatably mounted on the bottom of the body, and the input end of the atomizing nozzle is connected to the output end of the water supply tank via a pipe. A detection camera and a travel switching assembly are disposed on the body. The measuring camera is equipped with a cleaning component. When the device is working, it detects dust near the dust detector and the measuring camera, and controls the dust collection drive component to drive the floating dust suction head to absorb the dust floating in the air and the swaying angle of the dust collection suction head when absorbing dust on the ground. This allows the device to collect dust on the ground while absorbing dust in the air. Then, the walking switching component can enable the device to walk along the subway track and on the ground. When the device moves, the water supply tank supplies water to the atomizing nozzle to spray water on the ground to prevent the dust collection suction head from not completely absorbing the dust on the ground, which would cause dust to be stirred up when the device passes by.

[0006] As a preferred technical solution, the walking switching assembly includes a base frame, track wheels, lifting rods, rotating seats, meshing gears, hydraulic rods, support seats, spherical rotating joints, vertical struts, flat wheels, fitting grooves, and oil supply tanks; A base frame is installed at the bottom of the machine body. Track wheels for traveling along the railway track are symmetrically rotatably mounted on the base frame. Lifting rods are installed at the axes of the track wheels within the machine body. Rotary seats are mounted on the lifting rods, and a pair of meshing gears are rotatably mounted within the rotary seats. Hydraulic rods are mounted on the meshing gears. Support seats are installed on the side walls of the machine body. Spherical rotating joints are rotatably mounted on the support seats. The hydraulic rods pass through the spherical rotating joints. Vertical support rods are mounted on the actuating end of the hydraulic rods. Flat wheels are rotatably mounted on the vertical support rods. Fitting grooves are formed on the inner sides of the flat wheels. Oil supply tanks are installed on both sides of the water supply tank. The oil supply tank is connected to the hydraulic rod on the same side via a hydraulic pipe. When the device needs to travel along the subway track, the oil supply tank supplies oil to the hydraulic rod. At this time, the hydraulic rod extends forward, causing the ground wheel to disengage from the track wheel. The distance between the ground wheels is greater than the width of the subway track. The device is then moved above the subway track. Subsequently, the lifting rod descends. At this time, a pair of meshing gears rotate under the drive of the swivel, causing the hydraulic rod to tilt upward around the spherical rotating joint, thereby causing the track wheel to slowly contact the subway track and the ground wheel to detach from the ground. When the device needs to travel on the ground, the operation is reversed and will not be described in detail. This completes the switching between the device traveling along the subway track and traveling on the ground.

[0007] As a preferred technical solution, the dust collection drive assembly includes an arc-shaped mounting plate, a rotating shaft, a sliding tube, a connecting column, a rotating rod, a rotating clamping rod, a connecting plate, a drive rod, an angle adjustment motor, a sliding clamping rod, a drive sleeve, an inner clamping groove, an outer clamping groove, and a drive box; A drive box and an arc-shaped mounting plate are installed in the cavity at the front end of the machine body. A rotating shaft is rotatably mounted on the arc-shaped mounting plate. A connecting column is mounted on the top of the rotating shaft. A rotating rod is rotatably mounted on the connecting column. A rotating locking rod is mounted on one end of the rotating rod. A connecting plate is mounted on the other end of the rotating rod. A drive rod is mounted on the connecting plate. A dust suction head is rotatably mounted on the top of the machine body. The bottom of the dust suction head is hinged to the top of the drive rod. A sliding tube is sleeved on the rotating shaft. A drive sleeve is slidably mounted on the sliding tube. An inner slot is opened in the drive sleeve. The rotating locking rod is located in the inner slot. An angle adjustment motor is mounted above the arc-shaped mounting plate. A sliding latch is installed on the output shaft of the machine. An external slot is provided on the drive sleeve. One end of the sliding latch is locked in the external slot. The first drive shaft of the drive box is driven by gear meshing with the bottom of the rotating shaft. When the device is vacuuming, the angle adjustment motor and drive box are controlled by the dust detector. At this time, the first drive shaft of the drive box drives the rotating shaft to rotate, which causes the drive rod to drive the dust suction head to rotate for angle adjustment. Then, the sliding latch on the angle adjustment motor drives the drive sleeve to slide up and down along the slide tube. The drive sleeve causes the rotating latch to drive the connecting column to rotate, which in turn causes the drive rod on the connecting plate to rotate, indirectly driving the dust suction head to rotate synchronously, thereby realizing multi-angle adjustment of the dust suction head.

[0008] As a preferred technical solution, the dust collection drive assembly further includes a reciprocating ring, internal meshing teeth, external meshing teeth, incomplete gears, driven wheel, actuator rod, driven shaft, and sliding mouth; A reciprocating ring is slidably mounted on the bottom of the arc-shaped mounting plate. Internal meshing teeth are symmetrically mounted on the inner ring of the reciprocating ring. A driven shaft is rotatably mounted on the bottom of the reciprocating ring, and an incomplete gear is mounted on the top of the driven shaft. The incomplete gear meshes with the internal meshing teeth. External meshing teeth are mounted on one side of the outer ring of the reciprocating ring, and a driven wheel is rotatably mounted near the reciprocating ring. An actuator is mounted on the driven wheel. A sliding opening is provided on the front side of the head of the machine body, through which the actuator passes. A dust collection nozzle is mounted at the end of the actuator. The second drive shaft of the drive box meshes with the driven shaft via gears. When the device vacuums, the second drive shaft of the drive box drives the incomplete gear on the driven shaft to rotate. Driven by the incomplete gear, the reciprocating ring moves back and forth. The reciprocating movement of the reciprocating ring causes the actuator to swing back and forth with the driven wheel, thereby enabling the dust collection nozzle to absorb dust in the fan-shaped area in front of the machine body.

[0009] As a preferred technical solution, the bottom of the drive rod is connected to the connecting plate and the connecting column via a ball joint.

[0010] As a preferred technical solution, both the end of the rotating locking rod embedded in the inner slot and the end of the sliding locking rod embedded in the outer slot are equipped with spherical contact heads.

[0011] As a preferred technical solution, a large gear is installed on the rotating end of the atomizing nozzle, a drive motor is installed on the base frame, a small gear for driving is installed on the output shaft of the drive motor, and the drive motor is electrically connected to the detection camera.

[0012] As a preferred technical solution, a lifting bracket is installed at the bottom of the machine body to lift the track wheel off the ground. The lifting bracket is electrically connected to the oil supply tank. When the device switches to the walking state, the lifting bracket lifts the device in advance so that the track wheel is lifted off the ground in advance. Thus, when the hydraulic rod is in the horizontal position and retracts, the flat wheel will not rub against the ground and cause damage.

[0013] As a preferred technical solution, the cleaning component includes a turntable, a swing arm, and a flexible scraper; A turntable is mounted on one side of the inspection camera, and a swing arm is mounted on the turntable. A flexible scraper is mounted on the swing arm, and the flexible scraper contacts the lens of the inspection camera. The turntable drives the swing arm to rotate, so that the flexible scraper cleans the lens of the inspection camera and prevents lens contamination.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. When the equipment is working, this application uses a dust detector and a detection camera to detect dust near the device, controls the dust collection drive component to drive the floating dust suction head to absorb dust floating in the air and the swaying angle of the dust collection suction head when absorbing dust on the ground, and then uses a walking switching component to enable the device to walk along the track and on the ground, and sprays the ground through atomizing nozzles to prevent dust from being generated when the device passes by.

[0015] 2. When the device needs to travel along the subway track, the oil supply tank supplies oil to the hydraulic rod. At this time, the hydraulic rod extends forward to disengage the ground wheel from the track wheel. Then, the device is moved above the subway track. Subsequently, the lifting rod descends, causing the hydraulic rod to tilt upward around the spherical rotating joint, so that the track wheel slowly contacts the subway track. When the device needs to travel on the ground, the operation is reversed and will not be described in detail. This completes the switching between the device traveling along the subway track and traveling on the ground.

[0016] 3. When the device is vacuuming, the dust detector controls the angle adjustment motor and drive box. At this time, the first drive shaft of the drive box drives the rotating shaft to rotate, which causes the drive rod to rotate the dust suction head to adjust the angle. Then, the sliding lever drives the drive sleeve to slide up and down along the slide tube, thereby driving the dust suction head to rotate synchronously. At the same time, the second drive shaft of the drive box drives the incomplete gear on the driven shaft to rotate. Under the drive of the incomplete gear, the reciprocating ring moves back and forth, causing the actuator to swing back and forth with the driven wheel, so that the dust suction head can absorb dust in the fan-shaped area in front of the machine body.

[0019] 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.

[0020] Example: Figures 1-6As shown, the subway construction dust collection device includes a body 1, inside which a filter 101, a suction device 102, and a water supply tank 107 are installed. A dust collection drive assembly 3 is also installed inside the body 1. The actuating end of the dust collection drive assembly 3 is equipped with a floating dust suction head 103 and a dust accumulation suction head 104, both of which are connected to the filter 101 via pipes. A dust detector 105 is installed on the top of the floating dust suction head 103. An atomizing nozzle 108 is rotatably installed at the bottom of the body 1, with its input end connected to the output end of the water supply tank 107 via a pipe. A detection camera 106 and a travel switching assembly 2 are also installed on the body 1. The device is equipped with a cleaning component 9. When the device is working, the dust detector 105 and the detection camera 106 detect the dust near the device. The dust collection drive component 3 controls the floating dust suction head 103 to absorb the dust floating in the air and the swaying angle of the dust accumulation suction head 104 when absorbing the dust on the ground. This allows the device to collect dust on the ground while absorbing dust in the air. Then, the device can move along the subway track and on the ground through the walking switching component 2. When the device moves, the water supply tank 107 supplies water to the atomizing nozzle 108 to spray water on the ground to prevent the dust accumulation suction head 104 from not completely absorbing the dust on the ground, which would cause dust to be stirred up when the device passes by.

[0021] like Figure 4 and Figure 5 As shown, the walking switching assembly 2 includes a base frame 201, track wheels 202, lifting rods 203, swivel seats 204, meshing gears 205, hydraulic rods 206, support seats 207, spherical rotating joints 208, vertical struts 209, flat wheels 210, fitting grooves 2101, and oil supply tanks 211. A base frame 201 is installed at the bottom of the machine body 1. Track wheels 202 for traveling along the rails are symmetrically rotatably mounted on the base frame 201. Lifting rods 203 are installed at the axes of the track wheels 202 within the machine body 1. Rotary seats 204 are mounted on the lifting rods 203. A pair of meshing gears 205 are rotatably mounted within the rotary seats 204. Hydraulic rods 206 are mounted on the meshing gears 205. A support seat 207 is installed on the side wall of the machine body 1. A spherical rotating joint 208 is rotatably mounted on the support seat 207. The hydraulic rod 206 passes through the spherical rotating joint 208. A vertical support rod 209 is installed at the actuating end of the hydraulic rod 206. A flat wheel 210 is rotatably mounted on the vertical support rod 209. A fitting groove 2101 is opened inside the flat wheel 210. Oil supply valves are installed on both sides of the water supply tank 107. The oil supply tank 211 is connected to the hydraulic rod 206 on the same side via hydraulic pipes. When the device needs to travel along the subway track, the oil supply tank 211 supplies oil to the hydraulic rod 206. At this time, the hydraulic rod 206 extends forward, causing the ground wheel 210 to disengage from the track wheel 202. The distance between the ground wheels 210 is greater than the width of the subway track. The device is then moved above the subway track. Subsequently, the lifting rod 203 descends. At this time, a pair of meshing gears 205 rotate under the drive of the swivel 204, causing the hydraulic rod 206 to tilt upward around the spherical rotating joint 208, thereby causing the track wheel 202 to slowly contact the subway track and the ground wheel 210 to detach from the ground. When the device needs to travel on the ground, the operation is reversed and will not be described in detail. This completes the switching between the device traveling along the subway track and traveling on the ground.

[0022] like Figures 4-6 , Figure 8 and Figure 9 As shown, the dust collection drive assembly 3 includes an arc-shaped mounting plate 301, a rotating shaft 302, a sliding tube 303, a connecting column 304, a rotating rod 305, a rotating locking rod 306, a connecting plate 308, a drive rod 309, an angle adjustment motor 311, a sliding locking rod 312, a drive sleeve 313, an inner locking groove 3131, an outer locking groove 3132, and a drive box 314; A drive box 314 and an arc-shaped mounting plate 301 are installed in the cavity at the front end of the body 1. A rotating shaft 302 is rotatably mounted on the arc-shaped mounting plate 301. A connecting post 304 is mounted on the top of the rotating shaft 302. A rotating rod 305 is rotatably mounted on the connecting post 304. A rotating locking rod 306 is mounted on one end of the rotating rod 305. A connecting plate 308 is mounted on the other end of the rotating rod 305. A drive rod 309 is mounted on the connecting plate 308. A dust suction head 103 is rotatably mounted on the top of the body 1. The bottom of the dust suction head 103 is hinged to the top of the drive rod 309. A sliding tube 303 is sleeved on the rotating shaft 302. A drive sleeve 313 is slidably mounted on the sliding tube 303. An inner slot 3131 is opened in the drive sleeve 313. The rotating locking rod 306 is located in the inner slot 3131. An angle adjustment motor 311 is mounted above the arc-shaped mounting plate 301. An angle adjustment motor 311 is mounted on the output shaft of the angle adjustment motor 311. Equipped with a sliding lever 312, the drive sleeve 313 has an outer slot 3132. One end of the sliding lever 312 is engaged in the outer slot 3132. The first drive shaft of the drive box 314 is driven by gear meshing with the bottom of the rotating shaft 302. When the device is vacuuming, the dust detector 105 controls the angle adjustment motor 311 and the drive box 314. At this time, the first drive shaft of the drive box 314 drives the rotating shaft 302 to rotate, causing the drive rod 309 to drive the dust suction head 103 to rotate for angle adjustment. Then, the sliding lever 312 on the angle adjustment motor 311 drives the drive sleeve 313 to slide up and down along the slide tube 303. The drive sleeve 313 causes the rotating lever 306 to drive the connecting column 304 to rotate, thereby causing the drive rod 309 on the connecting plate 308 to rotate, indirectly driving the dust suction head 103 to rotate synchronously, thus realizing the multi-angle adjustment of the dust suction head 103.

[0023] The dust collection drive assembly 3 also includes a reciprocating ring 315, an internal meshing gear 316, an external meshing gear 317, an incomplete gear 318, a driven wheel 319, an actuator 320, a driven shaft 321, and a sliding mouth 322; A reciprocating ring 315 is slidably mounted on the bottom of the arc-shaped mounting plate 301. Internal meshing teeth 316 are symmetrically mounted on the inner ring of the reciprocating ring 315. A driven shaft 321 is rotatably mounted on the bottom of the reciprocating ring 315. An incomplete gear 318 is mounted on the top of the driven shaft 321, meshing with the internal meshing teeth 316. External meshing teeth 317 are mounted on one side of the outer ring of the reciprocating ring 315. A driven wheel 319 is rotatably mounted on the side near the reciprocating ring 315, and an actuator rod 320 is mounted on the driven wheel 319. A sliding opening 322 is provided on the front side of the head position of the machine body 1. The actuator 320 passes through the slide 322, and the end of the actuator 320 is equipped with a dust collection head 104. The second drive shaft of the drive box 314 meshes with the driven shaft 321 through gears. When the device is vacuuming, the second drive shaft of the drive box 314 drives the incomplete gear 318 on the driven shaft 321 to rotate. Under the drive of the incomplete gear 318, the reciprocating ring 315 moves back and forth. Under the reciprocating movement of the reciprocating ring 315, the actuator 320 swings back and forth with the driven wheel 319, so that the dust collection head 104 can absorb dust in the fan-shaped area in front of the machine body 1.

[0024] The bottom of the drive rod 309 passes through the connecting plate 308 and is connected to the connecting column 304 via a ball joint 4.

[0025] Both the end of the rotating lever 306 that is embedded in the inner slot 3131 and the end of the sliding lever 312 that is embedded in the outer slot 3132 are equipped with ball-shaped contact heads 5.

[0026] like Figure 7 As shown, a large gear 6 is installed on the rotating end of the atomizing nozzle 108, a drive motor 7 is installed on the base frame 201, a small gear 8 for driving is installed on the output shaft of the drive motor 7, and the drive motor 7 is electrically connected to the detection camera 106.

[0027] The bottom of the machine body 1 is equipped with a lifting bracket 212 for lifting the track wheel 202 off the ground. The lifting bracket 212 is electrically connected to the oil supply tank 211. When the device switches to the walking state, the lifting bracket 212 lifts the device in advance so that the track wheel 202 is lifted off the ground in advance. Thus, when the hydraulic rod 206 is in the horizontal position and retracts, the flat wheel 210 will not rub against the ground and cause damage.

[0028] like Figure 2 and Figure 5 As shown, the cleaning component 9 includes a turntable 901, a swing arm 902, and a flexible scraper 903; A turntable 901 is installed on one side of the inspection camera 106. A swing arm 902 is installed on the turntable 901. A flexible scraper 903 is installed on the swing arm 902. The flexible scraper 903 contacts the lens of the inspection camera 106. The turntable 901 drives the swing arm 902 to rotate, so that the flexible scraper 903 cleans the lens of the inspection camera 106 and prevents lens contamination.

[0029] Working principle of the invention: When the device is working, the dust detector 105 and the detection camera 106 detect dust near the device. The dust collection drive component 3 controls the dust suction head 103 to absorb dust floating in the air and the dust collection suction head 104 to swing when absorbing dust on the ground. This allows the device to collect dust on the ground while absorbing dust in the air. The device can then move along the subway track and on the ground via the walking switch component 2. When the device moves, the water supply tank 107 supplies water to the atomizing nozzle 108 to spray water on the ground to prevent the dust collection suction head 104 from not completely absorbing the dust on the ground, which would cause dust to be stirred up when the device passes by.

[0030] When the device needs to travel along the subway track, the oil supply tank 211 supplies oil to the hydraulic rod 206. At this time, the hydraulic rod 206 extends forward, causing the leveling wheel 210 to disengage from the track wheel 202. The distance between the leveling wheels 210 is greater than the width of the subway track. The device is then moved above the subway track. Subsequently, the lifting rod 203 descends. At this time, a pair of meshing gears 205 rotate under the drive of the swivel 204, causing the hydraulic rod 206 to tilt upward around the spherical rotating joint 208, thereby causing the track wheel 202 to slowly contact the subway track and the leveling wheel 210 to detach from the ground. When the device needs to travel on the ground, the operation is reversed and will not be described in detail. This completes the switching between the device traveling along the subway track and traveling on the ground.

[0031] When the device switches to the walking mode, the lifting bracket 212 lifts the device in advance so that the track wheel 202 is lifted off the ground in advance. This prevents the flat wheel 210 from rubbing against the ground and causing damage when the hydraulic rod 206 is in the horizontal position and retracts.

[0032] When the device is vacuuming, the dust detector 105 controls the angle adjustment motor 311 and the drive box 314. At this time, the first drive shaft of the drive box 314 drives the rotating shaft 302 to rotate, which causes the drive rod 309 to drive the dust suction head 103 to rotate for angle adjustment. Then, the sliding latch 312 on the angle adjustment motor 311 drives the drive sleeve 313 to slide up and down along the slide tube 303. The drive sleeve 313 causes the rotating latch 306 to drive the connecting column 304 to rotate, which in turn causes the drive rod 309 on the connecting plate 308 to rotate, indirectly driving the dust suction head 103 to rotate synchronously, thereby realizing the multi-angle adjustment of the dust suction head 103.

[0033] When the device vacuums, the second drive shaft of the drive box 314 drives the incomplete gear 318 on the driven shaft 321 to rotate. Driven by the incomplete gear 318, the reciprocating ring 315 moves back and forth. The reciprocating movement of the reciprocating ring 315 causes the actuator 320 to swing back and forth with the driven wheel 319, thereby enabling the dust suction head 104 to absorb dust in the fan-shaped area in front of the machine body 1.

[0034] The turntable 901 drives the swing arm 902 to rotate, causing the flexible scraper 903 to clean the lens of the inspection camera 106 and prevent lens contamination.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
