Description

Technical Field

[0001] This invention relates to a track-type dust suppression device for construction dust control and its usage method, belonging to the field of mobile track technology. Background Technology

[0002] The track-mounted dust suppression device is a mobile environmental protection equipment used for dust control at construction sites. Its core structure consists of a track system laid above the construction area and intelligent spray units suspended on it. The device uses a track to move the spray heads horizontally, and combined with high-pressure atomization technology, it evenly sprays water mist onto the work surface, effectively adsorbing and settling dust particles in the air. Compared with fixed sprayers, this device has the advantages of wide coverage, precise location of dust sources, water saving and high efficiency. It is particularly suitable for large-area and dynamically changing construction scenarios such as foundation pit excavation, excavated soil transportation, and building demolition. It can significantly reduce the concentration of PM10 and other inhalable particulate matter, and improve the environmental quality of the construction site and its surroundings. During the sanding and painting of building exteriors, scaffolding is used for assistance. Workers need to move back and forth on the scaffolding during the work process. Existing dust suppression spray devices are generally installed on one side of the construction position, making it difficult to follow the movement of workers and achieve more precise dust suppression. Moreover, the air quality at the dust suppression work position is poor. In the case of a track structure with gear transmission, if a large amount of dust enters the engagement point between the gears and the gear plate during reciprocating movement, it will cause the entire moving structure to jam during the movement. Therefore, there is an urgent need to improve a track-type dust suppression device for construction dust control and its usage method to solve the above-mentioned problems. Summary of the Invention

[0003] The purpose of this invention is to provide a track-type dust suppression device and its usage method for construction dust control, in order to solve the problem that during the grinding and painting of building exterior walls, with the assistance of scaffolding, workers need to move back and forth on the scaffolding. Existing dust suppression spray devices are generally installed on one side of the construction position, which makes it difficult to follow the movement of workers and achieve more precise dust suppression. In addition, the air quality at the dust suppression work position is poor. In the case of a track structure with gear transmission, if a large amount of dust enters the engagement position between the gear and the gear plate during reciprocating movement, it will cause the entire moving structure to jam during the movement.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A track-type dust suppression device and its method of use for construction dust control includes a spraying assembly for dust control. The spraying assembly is installed on the upper end of a track. A detachable toothed plate is installed on one side of the upper end of the track by screws. A walking assembly with a self-cleaning structure is installed on one side of the toothed plate. The walking assembly includes a gear meshing with the toothed plate. A drive shaft with both upper and lower ends is fixedly connected to the middle of the gear. A bevel gear I is fixedly connected to the outer side of the upper end of the drive shaft. Bevel gear II with a diameter ratio of 1:4 meshes on both sides of bevel gear I. A horizontal shaft is fixedly connected to one end of bevel gear II. A rotating wheel is fixedly connected to the outer side of the other end of the horizontal shaft. Multiple cleaning bristles for cleaning the surface of the toothed plate are distributed in a ring on the outer side of the rotating wheel. Each cleaning bristle has a forked groove at its tip.

[0005] Furthermore, the track includes a track body, with positioning grooves on both sides of the track body and a square hole on the inner side of one end of the track body.

[0006] Furthermore, the spraying assembly includes a movable plate, with guide discs installed at the lower ends of all four ends of the movable plate. A spray head is fixedly connected to one side of the upper end of the movable plate, and a drive motor is fixedly connected to the other side of the upper end of the movable plate. The guide discs are connected to the track body through positioning grooves, and the top end of the drive motor spindle is fixedly connected to the transmission shaft.

[0007] Furthermore, the walking component is installed on the upper end of the connecting component. The connecting component includes a fixed base plate with a central hole in the middle. Vertical plates with rotating holes at the top are fixedly connected to both sides of the upper end of the fixed base plate. Slider blocks are fixedly connected to both ends of one side of the fixed base plate. L-shaped curved holes are opened at both ends of the fixed base plate, and jet nozzles are fixedly connected to the upper openings of the curved holes.

[0008] Furthermore, the fixed base plate is slidably connected inside the square hole by a slider, the fixed base plate is rotatably connected to the bottom end of the drive shaft through the central hole, and the upper end of the vertical plate is rotatably connected to the horizontal shaft through a rotating hole.

[0009] Furthermore, guide rods are fixedly connected to both ends of the fixed base plate, and the guide rods are slidably connected to the track body through a sealing structure.

[0010] Furthermore, a blower assembly is installed on the outer side of each of the guide rods. The blower assembly includes a telescopic sleeve, and a one-way valve is fixedly connected to the end of the telescopic sleeve away from the fixed base plate.

[0011] Furthermore, one end of the telescopic sleeve is fixedly connected to the inner wall of the square hole, the other end of the telescopic sleeve is fixedly connected to the fixed base plate, and the connection end of the telescopic sleeve and the fixed base plate is connected to the bent hole.

[0012] Furthermore, it includes the following steps: Step 1: Connect the spray head to the water supply pipe and connect the track body to the scaffolding that needs dust removal. After the connection is completed, spray water mist onto the construction site with the spray head and adjust the position of the spray head by following the construction site through the track. Step 2: The movement of the spray head is controlled by the movement of the entire spray assembly. During the movement of the spray assembly, the drive motor first drives the transmission shaft to rotate. As the transmission shaft rotates, it drives the gear, which in turn moves on one side of the gear plate. Step 3: During the rotation of the gears, the first bevel gear is driven to rotate synchronously. During the rotation of the first bevel gear, the second bevel gear is driven to rotate, which in turn drives the rotating wheel and cleaning bristles to rotate through the horizontal shaft. During the contact between the cleaning bristles and the toothed plate, they are used to clean the surface. Step 4: The connecting component moves synchronously with the spraying component. During the movement, the telescopic sleeve on one side is compressed, while the telescopic sleeve on the other side is stretched. The telescopic sleeve in the compression process transfers excess gas inside through the bend and the jet nozzle to the vicinity of the gear. The telescopic sleeve in the stretched state draws air into itself through the one-way valve.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the walking component allows for real-time processing of dust that falls or adheres to the toothed plate due to the working environment, while the spray head follows the worker to perform precise dust suppression. This effectively prevents a large amount of dust from adhering to the contact point between the gears and the toothed plate, thus avoiding transmission jamming and improving the smoothness of the internal transmission. 2. In this invention, by using the blower assembly in conjunction with the jet nozzle, during the reciprocating movement of the connecting assembly, one of the telescopic sleeves on both sides, which is in the compression process, can continuously blow gas towards the vicinity of the gear, thereby further cleaning up the fallen dust in a timely manner. 3. The device of the present invention adopts a modular design, which facilitates the replacement and upgrading of independent modules in the future. At the same time, the walking component and the connecting component are set at the upper end of the square hole, and the overall structure is exposed to the outside, which facilitates the removal of dust and subsequent maintenance.
