Technical Field

[0001] The present invention relates to the technical field of highway construction, and specifically to a drilling dust reduction construction process for highway construction. Background Art

[0002] Drilling dust reduction construction is one of the commonly used dust reduction measures in highway construction. It mainly controls dust by using water or other substances during the drilling process to reduce the spread of dust into the surrounding environment. The specific operation includes, when carrying out drilling operations, using water spraying or other dust reduction equipment to spray water onto the drilling position to form a water mist or water film to prevent the spread of dust. This can effectively reduce the dust and dust in the construction site, protect the health of construction workers and the surrounding environment, and is an environmentally friendly construction method. Such products include CN202320966721.2, a road drilling device for traffic engineering construction, CN202011248667.5, which discloses a drilling dust reduction device and process for highway construction, 202322077779.4, a highway construction drilling machine with dust prevention effect, and so on.

[0003] Among them, the patent with application number CN202011248667.5, which can carry out dust reduction, discloses a drilling dust reduction device and process for highway construction. Aiming at the problems that the existing drilling devices will generate a large amount of dust, and it is harmful to the health of construction workers to inhale dust for a long time, but the traditional sprinkler trucks are large in volume, inconvenient to use in some small construction sites, and will waste a large amount of water resources, and the dust removal effect is average, the following scheme is proposed. It includes a base, and a fixed box is fixedly connected to the top of the base. A drilling component for drilling is arranged inside the fixed box. The structure of the present invention is simple. The drilling function is realized through the drilling component, and the drilling depth is adjusted by rotating the screw. The dust suction disc surrounds the drill bit for one week, which is convenient for absorbing dust, has a good dust suction effect, then carries out dust reduction, uses less water, has a good dust reduction effect, will not pollute the ground, and no longer requires manual holding of the drilling device, reducing the burden on workers and being easy to operate.

[0004] However, the above technical solution can only achieve the most basic water spraying and cleaning work, and cannot change the water spraying amount according to the current drilling depth. If a small amount of water is used for continuous water spraying, the ideal dust reduction work cannot be achieved, but using a large amount of water for cleaning work all the time will waste water resources; and when carrying out dust reduction work, the drilling device is still exposed outdoors, and there will still be situations such as flying debris during drilling, resulting in low dust reduction efficiency.

[0050] When performing dust reduction work in step four, at this time, the cleaning mechanism 300 controls the fan blade 313 to perform air extraction work. At this time, a negative pressure vacuum state is formed between the clamping plate 11 and the road surface, further improving the stability of the construction device; when the drilling work is completed, at this time, the cleaning mechanism 300 controls the upper clamping block 307 to move up and down reciprocally, so that the pushing blocks 311 respectively strike and clean the filter screen and the fan blade 313, thereby realizing the cleaning work of the construction device.

[0051] Working principle: Move this drilling dust suppression construction device to the designated construction site, turn on the control switch, the output end of the driving motor 3 drives the lead screw 19 fixedly connected thereto to rotate. Under the limiting action of the limiting rod 9 on the sliding plate 5, the lead screw 19 drives the sliding plate 5 threadedly connected thereto to move downward. The sliding plate 5 drives the driving motor 6 to move downward. The output end of the driving motor 6 drives the rotating shaft 7 fixedly connected thereto to rotate. The rotating shaft 7 drives the drill bit 8 fixedly connected thereto to rotate, thereby realizing the drill bit 8 rotating and moving downward at the same time, so as to perform drilling work on the current position;

[0052] The lead screw 19 drives the rotating shaft 101 fixedly connected thereto to rotate. The rotating shaft 101 drives the driving bevel gear 102 fixedly connected thereto to rotate. The driving bevel gear 102 drives the driven bevel gear 103 meshed therewith to rotate. The driven bevel gear 103 drives the transmission shaft 104 fixedly connected thereto to rotate. The transmission shaft 104 drives the rotating disk 105 fixedly connected thereto to rotate. The rotating disk 105 drives the driving shaft 111 fixedly connected thereto to rotate. Under the limiting action of the matching plate 114 on the limiting plate 112 and the piston cylinder 106 on the piston rod 107, the driving shaft 111 realizes the left and right reciprocating motion of the sliding frame 109 by rotating in the chute 110. The chute 110 drives the L-shaped plate 113 fixedly connected thereto to perform left and right reciprocating motion. The L-shaped plate 113 drives the piston rod 107 fixedly connected thereto to perform left and right reciprocating motion. While the piston rod 107 performs left and right reciprocating motion, it controls the piston cylinder 106 to perform piston water spraying work. The piston cylinder 106 sprays out from the annular nozzle 115 through the adjusting mechanism 200, thereby realizing the water spraying and dust suppression work on the drill bit 8;

[0053] As the sliding plate 5 moves downward, the sliding plate 5 drives the convex block 17 fixedly connected thereto to move downward. When the convex block 17 moves downward, it contacts the control button 18. The control button 18 controls the controller 16 to turn on the electric control switch. The controller 16 controls the baffle 207 to rotate. The baffle 207 drives the fixed disk 203 fixedly connected thereto to rotate. The fixed disk 203 drives the baffle 207 to rotate through the hexagonal groove 206. Under the limiting action of the inclined groove 205 on the fixed shaft 208, six groups of baffles 207 perform a separating movement, thereby increasing the size of the communication opening between the water outlet 209 and the baffle 207. By setting three groups of controllers 16, the deeper the drill bit 8 descends, the larger the opening of the adjusting mechanism 200, and the more the water spraying amount of the water spraying mechanism 100 also increases, improving the cleaning and dust suppression effect on the drill bit 8;

[0054] The rotating shaft 101 drives the active runner 301 fixedly connected thereto to rotate. The active runner 301 drives the driven runner 303 to rotate through the transmission belt 302. The driven runner 303 drives the driven shaft 304 fixedly connected thereto to rotate. The driven shaft 304 drives the lower clamping block 306 fixedly connected thereto to rotate. At this time, when the lower clamping block 306 rotates, it will drive the upper clamping block 307 on the upper side to rotate synchronously through the vertical protruding part on the surface. The upper clamping block 307 drives the spline rod 312 fixedly connected thereto to rotate. The spline rod 312 drives the fan blade 313 spline-connected thereto to rotate, so that the card plate 11 performs air extraction work on the part of the road surface in a closed state. A state similar to a vacuum sucker is formed between the card plate 11 and the road surface, realizing stable drilling of the construction device while reducing the splashing of dust and debris;

[0055] After the drilling work is completed, the driving motor 3 controls the sliding plate 5 to rise. At this time, the lead screw 19 drives the rotating shaft 101 to rotate in the reverse direction. The rotating shaft 101 controls the lower clamping block 306 to rotate in the reverse direction. At this time, when the lower clamping block 306 rotates, it no longer drives the upper clamping block 307 to rotate. The arc surface part on the surface of the upper clamping block 307 moves upward under the push of the arc surface part of the lower clamping block 306. When the lower clamping block 306 no longer pushes the upper clamping block 307, the upper clamping block 307 moves downward under the spring tension of the return spring 314, thereby realizing the reciprocating up and down movement of the upper clamping block 307. The upper clamping block 307 drives the upper rotating ring 309 rotatably connected thereto to perform reciprocating up and down movement. The upper rotating ring 309 drives the connecting plate 310 fixedly connected thereto to perform reciprocating up and down movement. The connecting plate 310 drives the pushing block 311 fixedly connected thereto to perform reciprocating up and down movement.
