Description

Technical Field

[0001] This utility model relates to the field of green building technology, and more specifically, to a dust suppression spraying device for building demolition construction. Background Technology

[0002] With urbanization, buildings are constantly facing the need for upgrading and replacement, making demolition and renovation a crucial part of construction. Demolition methods are diverse, such as mechanical demolition, manual demolition, and blasting demolition, to ensure the effective handling of different building types. Therefore, the application of environmental protection technologies is receiving increasing attention, aiming to reduce noise, dust, and waste during the demolition process. This necessitates the use of spray dust suppression devices to reduce dust generated during building demolition.

[0003] A search revealed a Chinese patent application with patent number CN217594202U, which discloses a dust suppression spraying device for building demolition, comprising a base, a support frame, connectors, a loading platform, and a spraying guide mechanism. The support frame is a steel rectangular frame, and its lower part is fixedly connected to the base via limit screws. A loading platform is provided on the upper part of the support frame, and a spraying guide mechanism is provided inside the loading platform. The spraying guide mechanism includes a mounting frame, a loading frame, a feeding box, a telescopic plate, a drive motor, and a flow pump. The mounting frame is fixedly mounted on the loading platform, and the loading frame and feeding box are provided on the upper part of the mounting frame. A telescopic plate is provided inside the feeding box.

[0004] Although the aforementioned patent features a support frame on the upper part of the base, and a connector on the upper part of the support frame, allowing for height adjustment as needed and limiting via a limiting rod on the outside of the connector for ease of use, and a loading platform on the upper part of the connector for placing the spraying equipment, the following shortcomings still exist during use: 1. The device's height adjustment via the connector and limiting via the limiting rod is cumbersome to operate, and it is labor-intensive when the loading platform is too heavy; 2. The spray pipe of the device cannot be angled, limiting its applicability.

[0005] Therefore, there is an urgent need for a dust suppression spraying device for building demolition to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a dust suppression spraying device for building demolition construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A dust suppression spraying device for building demolition includes a support base, a symmetrically distributed support frame fixedly connected to the top wall of the support base, a sliding column slidably connected to the inner wall of the support frame, and a loading platform fixedly connected to the top wall of the sliding column. The device also includes:

[0009] A rotating base is fixedly connected to the outer wall of the loading platform. A short main plate is rotatably connected to the inner wall of the rotating base, and a short auxiliary plate is also rotatably connected to the inner wall of the rotating base.

[0010] An adjustable telescopic assembly includes an adjustable base fixedly connected to the top wall of a supporting base. A bidirectional screw is rotatably connected to the inner wall of the adjustable base. An L-shaped rod is fixedly connected to the outer wall of the bidirectional screw. A rotating sleeve is rotatably connected to the outer wall of the L-shaped rod. A symmetrically distributed slider is threaded to the outer wall of the bidirectional screw, and the slider is slidably connected to the adjustable base. A long main plate is rotatably connected to the inner wall of the adjustable base on the right side, and a long secondary plate is rotatably connected to the inner wall of the adjustable base on the left side. Multiple sets of long main plates and long secondary plates are arranged alternately. Evenly distributed fixing rods are fixedly connected between the long main plate and the short main plate. The short secondary plate and the long secondary plate are rotatably connected to the fixing rods.

[0011] A carrying rack is symmetrically and fixedly connected to the top wall of the carrying platform, and the top wall of the carrying rack is fixedly connected with symmetrically distributed fixing sleeves;

[0012] An angle adjustment component is located on the inner wall of the fixed sleeve.

[0013] As a preferred technical solution of this application, the angle adjustment component includes a pin rotatably connected to the inner wall of a fixed sleeve, a worm gear fixedly connected to the outer wall of the pin, a feeding box fixedly connected to the outer wall of the pin, a first drive motor fixedly connected to the outer wall of the feeding box, a worm fixedly connected to the output end of the first drive motor, and the outer wall of the worm meshing with the outer wall of the worm gear, a second drive motor fixedly connected to the outer wall of the feeding box, and a drive gear fixedly connected to the output end of the second drive motor.

[0014] As a preferred technical solution of this application, a telescopic plate is slidably connected to the inner wall of the feeding box, a spray pipe is fixedly connected to the inner wall of the telescopic plate, and a rack is fixedly connected to the outer wall of the telescopic plate, and the outer wall of the rack meshes with the outer wall of the drive gear.

[0015] As a preferred technical solution of this application, a diversion box is fixedly connected to the top wall of the cargo platform.

[0016] As a preferred technical solution of this application, a reinforcing frame is fixedly connected between adjacent support frames.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. By setting a rotating sleeve to drive the L-shaped rod and the double-ended screw to rotate, the double-ended screw and the slider are threaded together to drive the slider to move the long main plate and the long secondary plate connected to the slider. Since the long main plate, the long secondary plate, the short main plate and the short secondary plate are rotatably connected by a fixed rod, the whole is a rhomboid structure, which makes it easy to drive the rhomboid structure to change length with the movement of the slider, thereby pushing the loading platform to slide in the support frame through the sliding column. The structure is simple and easy to adjust, saving a lot of manpower. It solves the problem that the height of the loading platform is adjusted by connecting parts and limited by limit rods in the existing technology, which is relatively troublesome to operate and consumes a lot of manpower when the loading platform is too heavy.

[0020] 2. By setting the output end of the first drive motor to drive the worm to rotate, the worm gear is driven to rotate through the meshing transmission between the worm and the worm wheel, which in turn drives the pin to rotate. This causes the feeding box and the structure on the feeding box, including the spray pipe, to adjust the angle along the fixed sleeve. The self-locking mechanical characteristics of the worm and the worm wheel achieve the self-locking of the rotation angle of the feeding box. The structure is simple, expands the application range, and has higher flexibility. It solves the problem that the spray pipe cannot be adjusted in angle and the application range is limited in the existing technology. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figure 1-5 As shown, the dust suppression spraying device for building demolition construction proposed in this embodiment includes a support base 1, a symmetrically distributed support frame 2 fixedly connected to the top wall of the support base 1, a sliding column 4 slidably connected to the inner wall of the support frame 2, and a loading platform 5 fixedly connected to the top wall of the sliding column 4. It also includes:

[0030] The rotating base 12 is fixedly connected to the outer wall of the loading platform 5. The inner wall of the rotating base 12 is rotatably connected to the short main plate 14, and the inner wall of the rotating base 12 is also rotatably connected to the short auxiliary plate 13.

[0031] The adjustable telescopic assembly includes an adjustable base 8 fixedly connected to the top wall of a support base 1. A bidirectional screw 16 is rotatably connected to the inner wall of the adjustable base 8. An L-shaped rod 17 is fixedly connected to the outer wall of the bidirectional screw 16. A rotating sleeve 18 is rotatably connected to the outer wall of the L-shaped rod 17. A symmetrically distributed slider 9 is threadedly connected to the outer wall of the bidirectional screw 16, and the slider 9 is slidably connected to the adjustable base 8. A long main plate 11 is rotatably connected to the inner wall of the right-side adjustable base 8, and a long secondary plate 10 is rotatably connected to the inner wall of the left-side adjustable base 8. Multiple sets of long main plates 11 and long secondary plates 10 are arranged alternately. Evenly distributed fixing rods 15 are fixedly connected between the long main plate 11 and the short main plate 14. 3. The long auxiliary plate 10 is rotatably connected to the fixed rod 15. When the height of the loading platform 5 needs to be adjusted, simply hold the rotating sleeve 18 and rotate the L-shaped rod 17 through the rotating sleeve 18, which in turn drives the bidirectional screw 16 to rotate. Through the threaded engagement between the bidirectional screw 16 and the slider 9, the slider 9 is driven to slide within the adjusting base 8, thereby adjusting the distance between the long main plate 11 and the long auxiliary plate 10 located within the slider 9. This drives the rhomboid structure to extend and retract, and through the rotating base 12, pushes the loading platform 5 to slide within the support frame 2 via the sliding column 4, thus facilitating the adjustment of the height of the support frame 2. The bidirectional screw 16 and the slider 9 are threadedly connected, so there is no need for locking after height adjustment.

[0032] The shelf 7 is symmetrically and fixedly connected to the top wall of the platform 5, and the top wall of the shelf 7 is fixedly connected with symmetrically distributed fixing sleeves 24;

[0033] An angle adjustment component is located on the inner wall of the fixed sleeve 24.

[0034] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, the angle adjustment assembly further includes a pin 23 rotatably connected to the inner wall of the fixed sleeve 24, a worm gear 21 fixedly connected to the outer wall of the pin 23, a feeding box 22 fixedly connected to the outer wall of the pin 23, a first drive motor 19 fixedly connected to the outer wall of the feeding box 22, a worm 20 fixedly connected to the output end of the first drive motor 19, and the outer wall of the worm 20 meshing with the outer wall of the worm gear 21; a second drive motor 26 fixedly connected to the outer wall of the feeding box 22. The output end of the motor 26 is fixedly connected to the drive gear 27. When it is necessary to adjust the angle of the spray pipe 29 for spraying, it is only necessary to start the second drive motor 26. The output end of the second drive motor 26 drives the worm 20 to rotate. The meshing transmission between the worm 20 and the worm wheel 21 drives the worm wheel 21 to rotate, which in turn drives the pin 23 to rotate, thereby adjusting the feeding box 22 to rotate along the fixed sleeve 24. This allows the angle of the feeding box 22 and all structures on the feeding box 22, including the spray pipe 29, to be adjusted.

[0035] like Figure 4As shown, in a preferred embodiment, based on the above method, a telescopic plate 25 is slidably connected to the inner wall of the feeding box 22, a spray pipe 29 is fixedly connected to the inner wall of the telescopic plate 25, and a rack 28 is fixedly connected to the outer wall of the telescopic plate 25. The outer wall of the rack 28 is meshed with the outer wall of the drive gear 27. The output end of the second drive motor 26 drives the drive gear 27 to rotate. The meshing transmission between the drive gear 27 and the rack 28 drives the rack 28 to slide the telescopic plate 25 in the feeding box 22, thereby adjusting the position of the spray pipe 29 in the telescopic plate 25.

[0036] like Figure 1 As shown, in a preferred embodiment, based on the above method, a diversion box 6 is fixedly connected to the top wall of the loading platform 5. The diversion box 6 is connected to an external water source to provide water for the spray pipe 29.

[0037] like Figure 1 As shown, in a preferred embodiment, based on the above method, a reinforcing frame 3 is fixedly connected between adjacent support frames 2 to improve the structural strength between support frames 2.

[0038] Specifically, when using the dust suppression spraying device for building demolition: First, because the long main plate 11, long secondary plate 10, short main plate 14, and short secondary plate 13 are connected by a fixed rod 15 to form a rhomboid structure, when the height of the loading platform 5 needs to be adjusted, simply hold the rotating sleeve 18, which drives the L-shaped rod 17 to rotate, thereby driving the double-ended screw 16 to rotate. Through the threaded engagement between the double-ended screw 16 and the slider 9, the slider 9 slides within the adjusting base 8, thereby adjusting the distance between the long main plate 11 and the long secondary plate 10 located within the slider 9. This drives the rhomboid structure to extend and retract, and through the rotating base 12, pushes the loading platform 5 to slide within the support frame 2 via the sliding column 4, thus... Regarding the height adjustment of the support frame 2, the bidirectional screw 16 and the slider 9 are threadedly connected, eliminating the need for locking after height adjustment. When it is necessary to adjust the angle of the spray pipe 29 for spraying, it is only necessary to start the second drive motor 26. The output end of the second drive motor 26 drives the worm gear 20 to rotate. The meshing transmission between the worm gear 20 and the worm wheel 21 drives the worm wheel 21 to rotate, which in turn drives the pin 23 to rotate, thereby adjusting the feeding box 22 to rotate along the fixed sleeve 24. This allows for angle adjustment of the feeding box 22 and all structures on it, including the spray pipe 29. Furthermore, the special mechanical transmission structure between the worm wheel 21 and the worm gear 20 can achieve self-locking, thus maintaining the angle of the spray pipe 29 after rotation.

[0039] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
