Description

Technical Field

[0001] The invention relates to the technical field of environmental protection dust removal, in particular to an environmental protection dust reduction device for building construction. Background Art

[0002] During the construction process of construction projects, a large amount of dust and particulate matter will be generated. These dusts will not only harm the health of construction workers, but also cause serious pollution to the surrounding environment. In order to reduce dust pollution during the construction process, it is usually necessary to carry out dust reduction treatment on the dust generated during the construction process.

[0003] The dust suppression devices used in traditional construction mostly adopt static spray dust suppression and dust removal bubbles. Static spray dust suppression usually uses water to spray dust suppression over a large area for a long time. It has poor flexibility and is not conducive to water conservation. Although the flexibility of dust removal bubbles is improved, the dust suppression range is large and cannot be controlled. During the construction process, when a small-scale construction is carried out inside the building, the applicability of traditional spray dust suppression devices and dust removal bubbles is poor. They can only deal with the dust that drifts to the outside of the building, but cannot carry out dust reduction inside the building, which will not only cause harm to the health of the construction workers, but also pollute the indoor environment of the building. At the same time, the existing dust suppression devices can only spray water from top to bottom. When performing operations such as longitudinal grooving and grinding of the wall, the dust generated cannot be effectively treated.

[0004] Therefore, an environmentally friendly dust reduction device for construction is proposed to solve the problems raised in the above background technology. Summary of the invention

[0021] Preferably, the first rotating shaft is fixedly connected to the rear surface of the rear plate, the outer surface of the first rotating shaft is rotatably connected to an electric push rod, the telescopic end of the electric push rod is rotatably connected to a connecting rod, and the top end of the connecting rod and the rear plate are rotatably connected via an axis.

[0022] By adopting the above technical solution, the first rotating shaft is used to rotationally connect the electric push rod and the rear plate. When the electric push rod is started and retracted, it can drive the connecting rod to rotate with the upper end of the connecting rod as the center.

It only requires connecting the external water pipe and the external joint to the water supply, and then starting the motor to make the nozzle move back and forth within a certain range for spraying, and the nozzle will swing back and forth during the spraying process, which is convenient for dust reduction treatment in indoor buildings and small areas, avoiding the harm of dust particles in the construction process to the health of construction workers, and has a good environmental protection effect.

[0026] 2. In the present invention, the electric push rod is started to extend, and at this time the connecting rod cooperates with the connecting plate to drive the L-shaped plate to rotate.

[0032] A motor 405 is fixedly installed on the rear surface of the L-shaped plate 401 near the left end, and the output end of the motor 405 rotates through the rear surface of the L-shaped plate 401 and extends forward. The output end of the motor 405 is fixedly connected to one of the pulleys 403, and the front surface of the cover 402 is fixedly connected to a slide rail 407. A wave groove 408 is provided at the inner bottom of the L-shaped plate 401. After the motor 405 is started in conjunction with the reduction gear box, it can drive the pulley 403 on the left to rotate. At this time, under the action of the synchronous belt 404, the other pulley 403 will rotate synchronously, thereby limiting the running path of the synchronous belt 404, so that the synchronous belt 404 rotates around the two pulleys 403, and the slide rail 407 is used to limit the slide bar 503, and its maximum length does not exceed the length of the cover 402 to avoid blocking the pulling shaft 410.

[0033] An avoidance groove 502 is provided at the center of the outer surface of the walking frame 501, and the pulling shaft 410 rolls and fits with the inner surface wall of the avoidance groove 502 through the roller. The rear surface of the walking frame 501 is fixedly connected with a slide bar 503, and the slide bar 503 is slidably connected to the slide rail 407. An internal pipe 511 is installed inside the pipe rack 508, and the bottom end of the internal pipe 511 is located inside the swing frame 509 and the bottom end of the internal pipe 511 is fixedly connected to the water inlet of the nozzle 512. The front end of the pulling shaft 410 is rotatably connected to an X-shaped wheel frame, and each end of the X-shaped wheel frame is rotatably connected to a roller, and the roller and the avoidance groove 502 roll and fit together. The number of slide bars 503 groups is the same as the number of slide rails 407 groups, and each group of slide bars 503 is composed of two slide bars 503, and the slide bars 503 do not overlap with the avoidance groove 502 and extend to both sides of the walking frame 501.

When the travel frame 501 is moved to the left and right, the avoidance groove 502 can be used to pull the walking frame 501 to move left and right. When the pulling shaft 410 moves to the side and the up and down positions are swapped, the roller at the end of the pulling shaft 410 will move up and down inside the avoidance groove 502, and then drive the walking frame 501 to move in the opposite direction, thereby achieving the purpose of the walking frame 501 driving the nozzle 512 to reciprocate. When the walking frame 501 moves to the extreme side, it will be misaligned with the slide rail 407, and a part of the slide bar 503 extending outward will be reserved inside the slide rail 407. The pipe rack 508 is used to accommodate the built-in pipe 511, which is a hose, and the lower end of the built-in pipe 511 extends to the inside of the swing frame 509 to remain in a relaxed state. After being connected to the nozzle 512, the swing frame 509 can drive the nozzle 512 to swing back and forth without causing damage to the built-in pipe 511, thereby avoiding water leakage.

[0034] The bottom of the walking frame 501 is fixedly connected with a lowering sleeve 504, and the bottom of the lowering sleeve 504 is slidably connected with a reciprocating plate 505. The front surface of the reciprocating plate 505 is symmetrically fixedly connected with a clamp 507 near the edge. The outer surfaces of both sides of the swing frame 509 are symmetrically provided with open grooves 510. The clamp 507 slides with the open grooves 510 through a latch. The bottom of the reciprocating plate 505 is rotatably connected with a rotating pin 506 near the rear surface. The rotating pin 506 is inserted between the inner surface walls of the wave groove 408. The lowering sleeve 504 is mainly used to limit the reciprocating plate 505. The reciprocating plate 505 can stably move forward and backward when following the moving frame 501 to move left and right. The pin on the inner side of the chuck 507 is inserted into the open groove 510 on the surface of the swing frame 509. Therefore, when the chuck 507 follows the reciprocating plate 505 to move forward and backward, it can push the swing frame 509 and the nozzle 512 to swing forward and backward. When the reciprocating plate 505 follows the moving of the walking frame 501, the rotating pin 506 at the bottom will slide inside the wave groove 408. During the process, the front and rear positions of the rotating pin 506 will continue to change, thereby achieving the purpose of driving the reciprocating plate 505 to move forward and backward.

[0035] Universal wheels 102 are installed at the bottom of the counterweight seat 101 near the four corners, and the top of the counterweight seat 101 is fixedly connected to a rear plate 103 and a front plate 104, and the rear plate 103 and the front plate 104 are fixedly connected by a connecting sleeve, and the front surface of the rear plate 103 is fixedly connected to an arc-shaped block 106 near the middle of the left surface, and the outer surfaces of the rear plate 103 and the front plate 104 are provided with vertical limiting grooves 105 near the middle position. The counterweight seat 101 is mainly used to improve the stability of the device when it is deployed and used. By arranging universal wheels 102 at the bottom of the counterweight seat 101, it is convenient to move the device. The rear plate 103 and the front plate 104 cooperate to form a longitudinal bracket, and the limiting groove 105 is mainly used to limit the moving path of the extension shaft 203.

[0036] The use steps of the present invention are as follows: during construction, when a large amount of dust particles are generated by artificially mixing concrete indoors or in a small area, the device is moved to the construction position, and then the external water pipe and the external joint 206 are connected so that the water source supplies water to the internal pipe 511 through the water supply pipe 205, and finally the water is sprayed out in a mist form through the nozzle 512. Then, after the motor 405 is started to drive one of the pulleys 403 to rotate, the synchronous belt 404 will drive the clamping seat 409 and the pulling shaft 410 to start moving with the cooperation of the other pulley 403. During the movement of the pulling shaft 410, it will move along the moving path of the synchronous belt 404. The front end of the pulling shaft 410 is inserted into the avoidance groove 502 on the surface of the walking frame 501, so when the pulling shaft 410 moves left and right, it can pull the walking frame 501 and the nozzle 512 to move left and right. When the pulling shaft 410 moves to the side of the synchronous belt 404 and the up and down position changes, its end will slide up and down inside the avoidance groove 502, and then drive the walking frame 501 and the nozzle 512 to continue to move in the opposite direction, realizing the reciprocating spraying of the nozzle 512, and when the walking frame 501 moves left and right, the lower sliding sleeve 504 at the bottom of the walking frame 501 will simultaneously drive the reciprocating plate 505 to follow the movement, and the reciprocating plate 505 will move back and forth. The rotating pin 506 at the bottom of the reciprocating plate 505 is inserted into the wave groove 408 at the bottom of the L-shaped plate 401, so the reciprocating plate 505 will reciprocate back and forth during the movement. During this process, the clamp 507 at the front end of the reciprocating plate 505 cooperates with the open groove 510 on the surface of the swing frame 509 to drive the swing frame 509 to drive the nozzle 512 to swing back and forth at the bottom of the pipe rack 508, thereby expanding the spraying range of the nozzle 512, so that the water mist and dust particles in the air come into contact with each other to achieve the effect of dust reduction. The overall use of this device is convenient. It only needs to connect the external water pipe and the external joint 206 to the water supply, and then start the motor 405. The nozzle 512 can be moved back and forth within a certain range to spray, and can swing back and forth during the spraying process, which is convenient for dust reduction treatment in buildings and small areas, and prevents dust particles from causing harm to construction workers during the construction process, and has a good environmental protection effect. In addition, the nozzle 512 is connected through an internal pipe 511 installed inside the swing frame 509 and the pipe rack 508. The internal pipe 511 is made of a relatively soft material and has a certain length reserved. Therefore, when the water supply pipe 205 supplies water to the nozzle 512 through the internal pipe 511, even if the nozzle 512 swings, it will not cause damage to the internal pipe 511 and the water supply pipe 205.

[0037] Embodiment 2: Figure 1-Figure 6As shown, the difference between the combination embodiment and the basis is that the two first guide wheels 201 are rotatably connected between the outer surfaces of the rear plate 103 and the front plate 104 near the top, and the center of the inner surface wall of the movable wheel 202 is rotatably connected with an extension shaft 203, and the two ends of the extension shaft 203 respectively pass through the two limiting grooves 105 and extend outward, and the two ends of the extension shaft 203 are rotatably installed with counterweights 204, and the surface of the water supply pipe 205 passes above the wheel grooves of the two first guide wheels 201 and below the wheel grooves of the movable wheel 202, which plays a role in limiting the water supply pipe 205, and the extension shaft 203 passes through the two limiting grooves 105. The limit groove 105 serves to limit the movable wheel 202 so that it can only move vertically up and down. The counterweight block 204 is used to increase the weight of the movable wheel 202, so that when the spray assembly 5 approaches the bracket assembly 1 during movement, the movable wheel 202 can press down the middle position of the water supply pipe 205 so that it can be neatly retracted into the interior of the bracket assembly 1. When the spray assembly 5 is away from the bracket assembly 1, the right end of the water supply pipe 205 is pulled to drive the movable wheel 202 to move upward, thereby making the water supply pipe 205 move neatly outward, avoiding the problem of entanglement or even blockage of the water supply pipe 205.

[0038] A water supply pipe 205 is slidably arranged between the outer surfaces of the two first guide wheels 201 and the movable wheel 202. The outer surface of the water supply pipe 205 is clamped between the inner surface walls of the arc-shaped clamping block 106 near the left end. An external joint 206 is installed at the left end of the water supply pipe 205. The arc-shaped clamping block 106 uses friction to fix the water supply pipe 205, and makes the water supply pipe 205 near the water inlet end face the left side and upward respectively, so as to avoid the problem of easy bending after being pulled. The external joint 206 is used to connect the water supply pipe 205 to the water pipe on the construction site, so as to supply water to the device.

[0039] The top of the L-shaped plate 401 is rotatably connected to a second guide wheel 406 through a mounting plate near the left edge. The outer surface of the water supply pipe 205 and the wheel groove of the second guide wheel 406 are slidably fitted. The top of the walking frame 501 is fixedly connected to a steering seat 513. The outer surface of the water supply pipe 205 and the inner surface wall of the steering seat 513 are engaged. The right end of the water supply pipe 205 and the top of the built-in pipe 511 are fixedly connected through a joint. The second guide wheel 406 is installed at the upper left corner of the L-shaped plate 401 to control the water supply pipe. 205 plays a guiding role, and when the walking component 4 is adjusted to a vertical state, the second guide wheel 406 can prevent the water supply pipe 205 from rubbing against the synchronous belt 404, and the steering seat 513 fixes the water supply pipe 205 through friction, and the internal groove of the steering seat 513 is arc-shaped, so the water supply pipe 205 will not bend during the left and right movement of the walking frame 501. The water supply pipe 205 is connected to the built-in pipe 511 through a connecting joint, so that an external water source can be supplied to the nozzle 512 for spraying water to reduce dust.

[0040] The use steps of the present invention are as follows: when the nozzle 512 is moving, the end of the longer water supply pipe 205 close to the nozzle 512 will move along; when the nozzle 512 is close to the bracket assembly 1, under the action of the counterweight 204, the movable wheel 202 will press down the middle position of the water supply pipe 205; therefore, the excess water supply pipe 205 exposed outside the rear plate 103 and the front plate 104 will be neatly retracted into the bracket assembly 1; when the nozzle 512 is away from the bracket assembly 1, the right end of the water supply pipe 205 will be pulled to the right by the steering seat 513 under the action of friction; at this time, the counterweight 204 and the movable wheel 202 will move upward, thereby making the water supply pipe 205 move neatly outward; the design structure is simple; when the nozzle 512 is moving to spray and reduce dust, the water supply pipe 205 can maintain a stable water supply state, and there will be no problems of entanglement or even blockage; the use effect is better.

[0041] Embodiment 3: Figure 1-Figure 4 and Figure 7 As shown, the basis of the embodiment is slightly different in that the first rotating shaft 301 is fixedly connected to the rear surface of the rear plate 103, the outer surface of the first rotating shaft 301 is rotatably connected to the electric push rod 302, the telescopic end of the electric push rod 302 is rotatably connected to the connecting rod 303, the top end of the connecting rod 303 and the rear plate 103 are rotatably connected through an axis, and the first rotating shaft 301 is used to rotatably connect the electric push rod 302 and the rear plate 103. When the electric push rod 302 is started and telescoped, it can drive the connecting rod 303 to rotate with the upper end of the connecting rod 303 as the center.

[0042] The connecting rod 303 is set at a 45° tilt, and a connecting plate 304 is fixedly connected to the outer surface of the connecting rod 303 near the top. The front surface of the connecting plate 304 and the rear surface of the L-shaped plate 401 are fixedly connected by bolts. The left surface of the L-shaped plate 401 fits against the right surface of the rear plate 103, and the lower left corner of the L-shaped plate 401 is located on the center line of the connecting rod 303. When the electric push rod 302 is retracted to the shortest length, the connecting rod 303 is tilted downward at 45°. At this time, the connecting rod 303 will drive the L-shaped plate 401 to rotate upward with the rotation point of the upper end of the connecting rod 303 as the center of the circle through the connecting plate 304, and the left surface of the L-shaped plate 401 will fit against the right surface of the rear plate 103 in the bracket assembly 1. After the electric push rod 302 is extended to the maximum length, the L-shaped plate 401 will rotate downward to a vertical state, and the initial bottom surface will fit against the right surface of the rear plate 103, thereby improving the stability of the L-shaped plate 401 in the horizontal and vertical states.

[0043] The use steps of the present invention are as follows: during the construction process, when it is necessary to grind the wall and dig longitudinal grooves for wiring and other operations, the electric push rod 302 is started to extend, and at this time the connecting rod 303 will rotate with the rotation point of the upper end as the center of the circle, and cooperate with the connecting plate 304 to drive the L-shaped plate 401 to rotate at the same time. When the electric push rod 302 is extended to the maximum length, the L-shaped plate 401 will rotate downward to a vertical state, and the surface will fit the right surface of the rear plate 103, and it has good stability. At this time, the nozzle 512 will face the left side, and will reciprocate up and down and swing back and forth at the same time when spraying water mist, which can reduce dust generated when grinding the wall and digging the longitudinal grooves. The functionality is strong and the use effect is further improved. The second guide wheel 406 is installed at the upper left corner of the L-shaped plate 401 to guide the water supply pipe 205, and when the walking component 4 is adjusted to a vertical state, the second guide wheel 406 can prevent the water supply pipe 205 from rubbing against the synchronous belt 404.

[0044] Among them, the electric push rod 302 and the motor 405 are both existing technologies, and their components and operating principles are all public technologies, and no further explanation is given here.
