DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] This specific embodiment is a tower crane spray device for dust removal, such as Figure 1 , Figure 2 and Figure 3 As shown, the dust removal tower crane spray device comprises a tower crane body 1 and a dust removal device 3 installed on the tower crane body 1, a water tank 2 for assisting the dust removal device 3 in supplying water is installed on the tower crane body 1, a water pump is installed inside the water tank 2, a conduit is installed on the water tank 2, the dust removal device 3 is installed on an extension arm on the tower crane body 1, the dust removal device 3 comprises a mounting seat 6, a conducting pipe 4 is installed transversely through the mounting seat 6, an embedded disk is fixedly sleeved at the middle section of the conducting pipe 4, the embedded disk is embedded and installed on the mounting seat 6, a nozzle 5 is installed on the outer side of the conducting pipe 4, and the spray nozzle 5 is installed on the outer side of the spray nozzle 5. A flow guide hole 51 is provided on the nozzle 5, a water outlet hole 43 is provided on the conducting pipe 4 corresponding to the nozzle 5, the water outlet hole 43 is connected with the flow guide hole 51, a protruding seat 11 is fixedly mounted on the outer edge of the bottom of the mounting seat 6, a conducting groove 111 is provided inside the protruding seat 11, a connecting pipe 12 is installed on the top of the protruding seat 11, a water inlet hole 41 is provided on the conducting pipe 4 corresponding to the embedded disk, the water inlet hole 41 is connected with the conducting groove 111, and a plurality of water inlet holes 41 are provided, and the plurality of water inlet holes 41 are arranged in a circular array at the outer edge of the conducting pipe 4 along the axis of the conducting pipe 4. A blocking plate 42 is fixed on the side of the embedded disk, and the conducting groove 111 is inclined toward the blocking plate 42.

[0028] By cooperating between the blocking plate 42 arranged on the conducting tube 4, the conducting groove 111 in the protruding seat 11, and the obliquely arranged guide hole 51, when the liquid enters the conducting tube 4, the blocking plate 42 is blown as a whole to drive the conducting tube 4 to rotate as a whole, and the guiding tube 4 is rotated as a whole under the action of the inclined guide hole 51, so that the liquid can be sprayed over a larger range, thereby avoiding the problem of limited liquid spraying range caused by a single nozzle position.

[0029] The nozzle 5 is cross-shaped and mounted on the conducting tube 4. The guide hole 51 is tilted inside the nozzle 5. The tilted guide hole 51 can generate a moving force during the flow of liquid, thereby performing secondary auxiliary rotation on the conducting tube 4.

[0030] Reference Figure 1 , Figure 2 and Figure 4 As shown, the blocking plate 42 is an arc-shaped plate structure, and a plurality of blocking plates 42 are provided. The plurality of blocking plates 42 are arranged in a circular array with the axis of the conducting pipe 4 as the center. The blocking plates 42 arranged in the circular array can be blown by the water flow at any angle of the conducting pipe 4 and drive the conducting pipe 4 to rotate as a whole.

[0031] Reference Figure 1 , Figure 4 and Figure 5As shown, a clamping cavity is opened at the top of the mounting seat 6, and a clamping assembly 7 is installed in the clamping cavity. The clamping assembly 7 is engaged with the extension arm on the tower crane body 1, and the clamping assembly 7 includes a bidirectional screw rod 9 rotatably arranged in the clamping cavity, and a slider 81 is symmetrically mounted on the bidirectional screw rod 9. The slider 81 is threadedly engaged with the bidirectional screw rod 9, and a clamping plate 8 is fixed at the top of the slider 81. One end of the bidirectional screw rod 9 extends out of the clamping cavity, and a knob 10 is fixed to the end of the bidirectional screw rod 9 extending out of the clamping cavity.

[0032] By setting the clamping assembly 7 on the mounting seat 6, the mounting seat 6 is placed on the extension arm, and the knob 10 is turned. The knob 10 drives the bidirectional screw rod 9 to rotate as a whole, and the slider 81 is threadedly matched with the bidirectional screw rod 9, so that the slider 81 moves as a whole, and then the clamping plate 8 is moved to the specified position, and then the clamping plate 8 is moved and connected to the outer side of the extension arm, which can facilitate the rapid disassembly of the clamping assembly 7 during subsequent disassembly, and try to avoid the problem of inconvenience in disassembling the clamping assembly 7 as a whole.

[0033] The bottom of the clamping plate 8 is symmetrically protruding with a guide block 82, and the top of the mounting seat 6 is symmetrically provided with a limit groove 61. The limit groove 61 and the guide block 82 cooperate and slide with each other. The guide block 82 is set up, so that the clamping plate 8 can only move horizontally on the top of the mounting seat 6 during operation, and can play an auxiliary guiding role in the process of adjusting the clamping plate 8, so as to avoid the misalignment of the clamping plate 8 as much as possible.

[0034] Working principle:

[0035] When the dust removal device 3 needs to be installed, the mounting base 6 is placed on the extension arm, and the knob 10 is turned. The knob 10 drives the bidirectional screw 9 to rotate as a whole. The slider 81 and the bidirectional screw 9 are threadedly matched, so that the slider 81 moves as a whole, and then the clamping plate 8 is moved to the specified position, and then the clamping plate 8 is moved and clamped and installed on the outer side of the extension arm, thereby completing the overall installation of the dust removal device 3.

[0036] When performing spraying, the connecting pipe 12 is connected to the water tank 2 through a conduit, and the water pump inside the water tank 2 is started to allow the spraying liquid to enter the connecting pipe 12 and flow along the conducting groove 111 as a whole. The flowing liquid pushes the blocking plate 42 to rotate as a whole, and then the conducting pipe 4 rotates as a whole. After the liquid pushes the blocking plate 42 to rotate as a whole, it enters the conducting pipe 4 through the water inlet hole 41 and is sprayed out as a whole along the nozzle 5 on the conducting pipe 4. During the spraying process, the nozzle 5 is driven to rotate as a whole through the inclined guide hole 51, and then the conducting pipe 4 is driven to rotate as a whole. Therefore, during the spraying process, the liquid is sprayed to a farther position through the rotation of the conducting pipe 4, thereby realizing the tower crane spraying process.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
