Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction and environmental protection, in particular to dust reduction equipment for road and bridge construction. Background Art

[0002] Dust pollution is a major environmental issue during road and bridge construction. Construction dust not only degrades air quality but can also cause respiratory illnesses among construction workers and surrounding residents. Road and bridge projects typically feature long construction intervals and dispersed working surfaces. Traditional dust suppression equipment struggles to adapt to these dynamic construction demands, exacerbating the difficulty of dust control.

[0003] Most existing dust removal equipment achieves dust reduction by spraying water mist through fog cannons or pipe-laid nozzles. However, fog cannons are large in size, occupy a large amount of road space, and have poor flexibility in narrow bridge sections or cross-operation areas. In addition, the water mist sprayed by fog cannons follows a parabolic trajectory. The amount of water mist is large at the landing point, and the water mist is small below the path. Its coverage is insufficient, affecting the dust reduction effect. Although traditional water pipe spraying has low cost, due to the long construction distance of bridges, hundreds of meters of water pipes need to be laid, and the position needs to be frequently adjusted as the project progresses, making its laying too difficult. In addition, the water pipes are easily damaged by construction vehicles, affecting subsequent dust reduction operations. Utility Model Content

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Please see the attached Figure 1-7 , this embodiment is a dust suppression equipment for road and bridge construction: it includes a mounting base 1, a support rod 2 is fixedly connected to the mounting base 1, and two symmetrically distributed receiving slots 3 are provided on the support rod 2, and the upper ends of the two receiving slots 3 are hinged with an adjusting support rod 4, and a folding bracket 5 is provided on the front side of the adjusting support rod 4. A plurality of groups of high-pressure nozzles 6 are fixedly connected to the folding bracket 5, and the plurality of groups of high-pressure nozzles 6 are connected in series through a connecting pipe 7. The positioning end of the folding bracket 5 is hinged to the adjusting support rod 4, and the traction end of the folding bracket 5 is hinged with a slider 8, which is slidably connected to the adjusting support rod 4, and a traction assembly 9 is fixedly connected to the rear side of the slider 8. As the adjusting support rod 4 opens, the traction assembly 9 synchronously unfolds the folding bracket 5.

[0025] The mounting base 1 is located at the bottom of the support rod 2. There are fixing holes on the mounting base 1 on the left and right sides of the support rod 2. During the construction of the road bridge, the support rod 2 is fixed to the side of the construction road bridge through the cooperation of the fixing holes on the mounting base 1 and the anchor bolts. This does not take up space on the road surface and is convenient for the movement of construction equipment on the construction road surface. The upper end of the support rod 2 is a stepped cylinder. There are storage grooves 3 on the left and right sides of the support rod 2. A group of adjustment rods 4 are hinged in each of the two storage grooves 3. The two adjustment rods 4 are rotated downward into the storage grooves 3 in the initial state. This can reduce the overall horizontal displacement of the device. To the width, it is convenient for the transportation of the device. When in use, the two adjusting rods 4 are rotated upward and the two adjusting rods 4 are adjusted to a horizontal state. In this way, the extended length of the two adjusting rods 4 on both sides of the support rod 2 is maximized. The two adjusting rods 4 are both equipped with folding brackets 5 and high-pressure nozzles 6. During the upward rotation of the adjusting rods 4, the traction assembly 9 unfolds the folding bracket 5 and lays it flat on the front side of the adjusting rod 4. In this way, a plurality of equally spaced high-pressure nozzles 6 are arranged on the front sides of the two adjusting rods 4, which can have a larger range of action when performing dust reduction and achieve better dust reduction effect.

[0026] like Figure 2 and Figure 4 As shown, the end of the folding bracket 5 close to the support rod 2 is the positioning end, the positioning end is hinged to the adjustment support rod 4, and the end away from the support rod 2 is the traction end. The traction assembly 9 drives the traction end to move left and right on the adjustment bracket. When the traction end is away from the support rod 2, the folding bracket 5 slowly opens outward. On the contrary, the folding bracket 5 contracts. The folding bracket 5 is composed of two first support rods, two second support rods and multiple groups of folding links 503. The first link 501 and the second link 502 are staggered front and back and have the same specifications. The middle part of the folding link 503 is hinged. The folding link 5 03. The first connecting rod 501 and the second connecting rod 502 cooperate with each other to form a plurality of diamond-shaped connection structures. When the slider 8 drives the traction end of the folding bracket 5 to move, the hinge point in the middle of the diamond-shaped connection structure spreads outward at equal intervals. The middle part of the folding connecting rod 503 is hinged by the connecting pin 504, and the middle parts of the first connecting rod 501 and the second connecting rod 502 are hinged by the hinge pin shaft. The high-pressure nozzle 6 is installed on the pin shaft and the connecting pin 504. This can ensure that after the folding assembly is unfolded, each high-pressure nozzle 6 can be arranged at equal intervals, thereby ensuring a uniform dust reduction effect within this range.

[0027] The slide groove 10 guides the movement of the slider 8 and the connecting pin 504, ensuring that the folding bracket 5 moves in the horizontal direction when it is unfolded or retracted, so that the folding bracket 5 can be folded or unfolded smoothly.

[0028] like Figure 2As shown, the middle part of the adjustment bracket is hinged to the third connecting rod 11, and the lower end of the third connecting rod 11 is hinged to the telescopic rod 12. The telescopic rod 12 is a hydraulic telescopic rod 12. In order to reduce the overall weight of the device, the support rod 2 is a hollow structure. The telescopic rod 12 can be arranged inside the support rod 2. This not only avoids erosion by external humid air, but also plays a role in vertically adjusting the third connecting rod 11. The outer rod of the telescopic rod 12 is fixedly connected to the inside of the support rod 2, and its inner stem is hinged to the third connecting rod 11 at the upper end through a through hole.

[0029] After the traction rope 901 is straightened, the traction rope 901 pulls the slider 8 and the reset pull rod 904 to move outward along the slide groove 10, and the reset pull rod 904 overcomes the reverse force of the elastic member.

[0030] A protective block 905 is installed on the rear side of the adjustment bracket, and the reset rod 904 and the spring 907 are both located in the protective shell. The spring 907 is sleeved on the reset rod 904. Figure 7 As shown, the spring 907 has an inward elastic force on the baffle, and the diameter of the baffle is the same as the diameter of the guide groove 906. The guide groove 906 guides the movement of the reset rod 904. The reverse force of the spring 907 on the reset rod 904 is used to complete the folding of the folding assembly when the traction rope 901 has no traction force; the protective shell protects the internal spring 907 and reduces erosion by the external environment.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
