Description

Technical Field

[0001] The invention belongs to the technical field of construction site dust reduction, and in particular relates to a hanging tower water spraying device. Background Art

[0002] During the construction of high-rise buildings, water spraying is mainly used for dust removal at the construction site. It is necessary to install a temporary water supply pipe for spraying water in the high-rise building currently under construction. However, in actual construction, the disassembly and assembly of the temporary water supply pipe is labor-intensive and time-consuming, and the dust removal area is limited, resulting in low dust removal efficiency. The tower crane water spray system refers to a water spray system preset by the tower crane rotating arm after the tower crane is installed. It is effective for dust removal, floor maintenance, and external fire fighting water in a certain area.

[0003] A Chinese patent discloses a dust removal tower crane, and its publication number is (CN206566659U). The patent sets a nozzle on a rotating water distribution part, which rotates during spraying to further spread the sprayed water around the tank by centrifugal force, thereby expanding the spraying range and improving the dust reduction efficiency. However, the length of the boom of the patent is fixed, so that the rotation radius of the boom is limited. At this time, although the spray range under the boom is increased, the overall spray radius of the patent cannot be changed, thereby reducing the actual practicality of the device.

[0006] Preferably, a sliding groove cooperating with the movable nozzle is provided on the bottom surface of the tower crane arm, and the movable nozzle is slidably connected to the inner wall of the sliding groove.

[0007] Preferably, there is an angle of forty-five degrees between the fixed nozzle and the long side of the boom, and there is an angle of forty-five degrees between the movable nozzle and the long side of the boom.

Therefore, the area coverage speed of the device is improved when spraying a large area. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the present embodiment: the workers on the ground control the motor to drive the rotating shaft to rotate, and the rotating shaft drives the rotating seat 21 to rotate, thereby driving the entire tower body 1 to rotate. The rotation principle of the rotating mechanism 2 driving the rotating seat 21 is consistent with the principle of the ground workers driving the tower crane body to rotate through the turntable in the specification of the tower crane with bidirectional rotation function disclosed in the Chinese patent (publication number: CN203529818U). The management warehouse 13 above the tower body 1 is mainly used to connect multiple tower crane arms 3. Since the tower crane arms 3 are fixedly connected with fixed water supply pipes 4 and mobile water supply pipes 5, a delivery pipeline for supplying fixed water supply pipes 4 and mobile water supply pipes 5 is installed in the management warehouse 13. The tower crane arm 3 separates the mobile water supply pipe 5 from the fixed water supply pipe 4 through a partition plate 31. The length of the fixed water supply pipe 4 matches the tower crane arm 3. The boom 3 forms a first spray circle 300. Since the tower boom 3 cannot move, the radius of the first spray circle 300 cannot be changed. However, the spray radius can still be changed by setting the mobile water supply pipe 5. When the driving motor 6 (model: iHSV60-30-40-48) drives the driving gear 61 to rotate, the driving gear 61 rotates in the driving groove 63, and the driving gear 61 cooperates with the moving rack 53, so that the sliding rib 52 slides in the limiting groove 621 of the limiting slide rail 62, thereby pushing the mobile water supply pipe 5 to the outside. At this time, the mobile nozzle 51 on the bottom surface of the mobile water supply pipe 5 is rotated by the tower boom 3 to form a second spray circle 400. The diameter of the second spray circle 400 can be arbitrarily changed on the basis of the first spray circle 300, thereby increasing the dust reduction spray radius, thereby increasing the practicality of the device.

[0027] exist Figure 2 In the figure, a sliding groove 33 matching with the moving nozzle 51 is provided on the bottom surface of the tower crane arm 3, and the moving nozzle 51 is slidably connected to the inner wall of the sliding groove 33; through the sliding groove 33, the moving nozzle 51 is still located below the tower crane arm 3 when sliding.

[0028] exist Figure 2 In the embodiment, there is an angle of forty-five degrees between the fixed nozzle 41 and the long side 100 of the boom, an angle of forty-five degrees between the movable nozzle 51 and the long side 100 of the boom, an angle of forty-five degrees between the fixed nozzle 41 and the short side 200 of the boom, and an angle of forty-five degrees between the movable nozzle 51 and the short side 200 of the boom; since there are angles between the fixed nozzle 41, the movable nozzle 51 and the long side 100 of the boom and the short side 200 of the boom, the area of ​​the first injection fan 301 formed by the fixed nozzle 41 increases, and the area of ​​the second injection fan 401 formed by the movable nozzle 51 increases. When the first injection circle 300 is used as the injection radius, the areas of the first injection fan 301 and the second injection fan 401 are added because there is no overlap, and the areas of the first injection fan 301 and the second injection fan 401 are relatively large, so the area coverage speed of the device is improved when spraying a large area.

[0029] exist Figure 1 In the figure, two water tanks 11 are fixedly connected to the upper end surface of the rotating seat 21, and a water inlet pipe 12 is provided on one side of the water tank 11; a pump is arranged inside the water tank 11, and a water supply pipeline is connected through the pump, and water is supplied to the mobile water supply pipe 5 and the fixed water supply pipe 4 through the water supply pipeline, and the stored water is transported into the water tank 11 through the water inlet pipe 12.

[0030] exist Figure 5 In the figure, the mobile water supply pipe 5 and the water tank 11 are sealedly connected by a connecting hose 54, and the connecting hose 54 has a reserved length, which is greater than the length of the mobile water supply pipe 5. Since the mobile water supply pipe 5 needs to slide, a connecting hose 54 is used and the reserved length is used so that the mobile water supply pipe 5 can still receive supply water when it moves.

[0031] exist Figure 2 In the embodiment, the contact surface between the limiting groove 621 and the sliding rib 52 is rotatably connected with a plurality of evenly distributed balls; the sliding friction between the sliding rib 52 and the limiting groove 621 can be reduced by the balls.

[0032] The working principle and use process of the present invention are as follows: the management warehouse 13 above the tower body 1 is mainly used to connect multiple tower crane arms 3. Since the tower crane arms 3 are fixedly connected with fixed water supply pipes 4 and mobile water supply pipes 5, a delivery pipeline for supplying the fixed water supply pipes 4 and the mobile water supply pipes 5 is installed in the management warehouse 13. The tower crane arm 3 separates the mobile water supply pipe 5 from the fixed water supply pipe 4 through a partition plate 31. The length of the fixed water supply pipe 4 matches the tower crane arm 3. The first injection circle 300 is formed by the fixed water supply pipe 4 and the tower crane arm 3. Since the tower crane arm 3 cannot move, the radius of the first injection circle 300 cannot be changed. However, the injection radius can still be changed by setting the mobile water supply pipe 5. When the driving motor 6 drives the driving gear 61 to rotate, the driving gear 61 rotates in the driving groove 63, and the driving gear 61 cooperates with the mobile rack 53, so that the sliding rib 52 is in the limiting groove 6 of the limiting slide rail 62. 21, thereby pushing the mobile water supply pipe 5 outward, at this time, the mobile nozzle 51 on the bottom surface of the mobile water supply pipe 5 is rotated by the tower crane 3 to form a second injection circle 400, and the diameter of the second injection circle 400 can be arbitrarily changed on the basis of the first injection circle 300, so that the dust reduction injection radius is increased, thereby increasing the practicality of the device, since there is an angle between the fixed nozzle 41, the mobile nozzle 51 and the long side 100 of the boom and the short side 200 of the boom, at this time, the area of ​​the first injection fan 301 formed by the fixed nozzle 41 increases, and the area of ​​the second injection fan 401 formed by the mobile nozzle 51 increases. When the first injection circle 300 is used as the injection radius, the areas of the first injection fan 301 and the second injection fan 401 are added because there is no overlap, and the areas of the first injection fan 301 and the second injection fan 401 are relatively large, so the area coverage speed of the device is improved when spraying over a large area.

[0033] Finally, it should be noted that the above description 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 replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
