Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a dust suppression and cooling device for building construction work surfaces. Background Technology

[0002] Construction work is a complex engineering activity, typically involving extensive excavation, cutting, and concrete pouring. These operations generate significant amounts of dust on construction sites, polluting the air, impacting the health of workers and the surrounding environment, and potentially damaging precision equipment and construction materials. Furthermore, in hot weather, construction sites easily accumulate heat, leading to excessively high working temperatures, affecting construction efficiency and worker safety. Therefore, the use of dust suppression and cooling devices during construction is particularly important. These devices can effectively reduce the dust content in the air and provide cooling to the construction site, ensuring smooth construction progress.

[0003] Traditional spray dust suppression devices typically include a water pump, pipes, and nozzles. The water pump delivers water to each nozzle, which then sprays the water to form a fine mist that captures dust particles in the air, thus achieving dust suppression. These devices are usually fixed in place, and the nozzle angles are relatively fixed, making it difficult to flexibly adjust the spray coverage according to actual working conditions. This makes it difficult to meet the needs of large-area construction sites. Therefore, a spray dust suppression and cooling device for construction work surfaces is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dust suppression and cooling device for construction work surfaces, aiming to improve the problem that the nozzle arrangement angle in the prior art is relatively fixed, making it inconvenient to flexibly adjust the spray coverage according to actual working conditions.

[0011] The guiding mechanism also includes a fixed base, which is fixedly connected to the top of the lifting frame, and the rotating shaft is rotatably connected inside the fixed base;

The connecting shaft is rotatably connected inside the support frame and fixedly connected to the side wall of the spray nozzle.

[0014] As a further description of the above technical solution:

[0015] The adjustment mechanism includes a connecting frame, the side wall of which is fixedly connected to one end of the spray nozzle, and a circular frame is provided inside the connecting frame, with a baffle rotatably connected inside the circular frame.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of a dust suppression and cooling device for construction work surfaces, comprising a body 1, a spray nozzle 2 on the top of the body 1 (spray nozzle 2 is existing technology and will not be described in detail here), a support mechanism on the top of the body 1 to enhance the stability of the spray nozzle 2, a fixed frame 3 fixedly connected to the bottom of the spray nozzle 2, a hydraulic rod 4 inside the body 1, and a lifting frame 5 fixedly connected to the output end of the hydraulic rod 4, which moves the lifting frame 5 by pushing it. The side wall of the lifting frame 5 is slidably connected to the inside of the body 1, and a guide mechanism is provided on the top of the lifting frame 5. A water tank 10 is inside the body 1, and the water tank 10 is connected to the spray nozzle 2 by a hose 11; the guide mechanism... It is used to move the spray nozzle 2. The guiding mechanism includes a rotating shaft 7, which is slidably connected to the side wall of the fixed frame 3. The guiding mechanism also includes a fixed seat 6, which is fixedly connected to the top of the lifting frame 5. The rotating shaft 7 is rotatably connected inside the fixed seat 6. The angle of the spray nozzle 2 is adjusted by the guiding mechanism to ensure that the coverage of the spray is maximized, thereby more effectively achieving the purpose of dust reduction and cooling. The support mechanism is used to support one side of the spray nozzle 2 and fix it to the top of the machine body 1. The support mechanism includes a support frame 8 and a connecting shaft 9. The support frame 8 is set on both sides of the spray nozzle 2 and connected to the machine body 1. The connecting shaft 9 is rotatably connected inside the support frame 8 and fixedly connected to the side wall of the spray nozzle 2.

[0035] When adjusting the tilt angle of the spray nozzle 2 during operation, the hydraulic rod 4 is activated to push the lifting frame 5 upward. As the lifting frame 5 rises, the fixed seat 6 also moves upward. At this time, the rotating shaft 7 is located inside the fixed seat 6. During the lifting process, the rotating shaft 7 not only deflects inside the fixed seat 6 but also slides on the surface of the fixed frame 3. As the hydraulic rod 4 continues to push, the fixed seat 6 gradually rises. The sliding and deflecting actions of the rotating shaft 7 will directly affect the position and angle of the spray nozzle 2. One side of the spray nozzle 2 will be gradually pushed upward by the force of the rotating shaft 7. At the same time, the other side of the spray nozzle 2, due to its connection with the connecting shaft 9, will deflect accordingly inside the support frame 8. This deflection design ensures that the spray nozzle 2 can automatically adjust its tilt angle under force.

[0036] Reference Figure 4An adjustment mechanism is located on the side wall of the spray nozzle 2 to adjust the water flow rate. The adjustment mechanism includes a connecting frame 12, which is fixedly connected to one end of the spray nozzle 2. A circular ring frame 13 is provided inside the connecting frame 12. A baffle 14 is rotatably connected inside the circular ring frame 13. A rotating ring 16 is rotatably connected inside the connecting frame 12. A lever 19 is fixedly connected to the side wall of the rotating ring 16 and is slidably connected inside the connecting frame 12. A limit post 17 is fixedly connected inside the connecting frame 12. A sliding groove 18 is opened inside the rotating ring 16 and the limit post 17 is slidably connected inside the sliding groove 18. A connecting plate 15 is rotatably connected to the side wall of the baffle 14 and is rotatably connected to the inside of the rotating ring 16 on one side. A nozzle 20 is fixedly connected to the side wall of the connecting frame 12.

[0037] When it is necessary to change the size of the water flow from the spray nozzle 2, the operator can precisely control the water flow by adjusting the lever 19. Moving the lever 19 causes the connected rotating ring 16 to rotate inside the connecting frame 12. Since the rotating ring 16 is connected to the connecting plate 15, as the rotating ring 16 rotates, one side of the connecting plate 15 also moves accordingly. When one side of the connecting plate 15 is rotated, the other side of the connecting plate 15 rotates synchronously with the baffle 14 and pulls it to move. At this time, the baffle 14 also deflects inside the ring frame 13, thereby changing the spacing between the multiple baffles 14. The spacing of the baffles 14 directly determines the size of the water outlet of the spray nozzle 2. By increasing the spacing between the baffles 14, the water outlet can be enlarged, allowing more water to be sprayed out, thus increasing the water flow of the spray nozzle 2; conversely, decreasing the spacing of the baffles 14 will limit the size of the water outlet, reducing the amount of water sprayed, thus effectively reducing the water flow. Therefore, the operator can easily adjust the water flow simply by moving the lever 19.

[0038] Working principle: When using this equipment, first move the equipment to a suitable working position, and then push the lifting frame 5 upward by starting the hydraulic rod 4, thereby driving the fixed seat 6 to move upward. At the same time as moving, the rotating shaft 7 will deflect inside the fixed seat 6 and slide on the fixed frame 3, gradually pushing one side of the spray nozzle 2 upward. At this time, the other side of the spray nozzle 2 will deflect inside the support frame 8 through the connecting shaft 9, thereby changing the tilt angle of the spray nozzle 2.

[0039] When it is necessary to change the size of the water flow from the spray nozzle 2, the rotating ring 16 can be rotated inside the connecting frame 12 by moving the lever 19. When the connecting frame 12 rotates, it will cause one side of the connecting plate 15 to move. At this time, the other side of the connecting plate 15 will rotate on the baffle 14 and pull it to deflect inside the ring frame 13, thereby changing the size of the gap between the baffles 14. By changing the size of the gap, the water flow rate can be changed.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
