[0029] The spraying piece 5 is arranged at the top end of the support assembly 4.

[0030] The winding assembly 6 is arranged in the power mechanism 2 and connected with the spraying piece 5.

[0031] The power mechanism 2 can provide power for the driving piece 3 and drive the support assembly 4 and the spraying piece 5 to ascend and descend when driving the winding assembly 6 to unwind, so as to adjust the use height of the spraying piece 5.

[0032] In this embodiment, before use, the winding assembly 6 is connected with the external water pipe, and the water is sprayed on the concrete through the spraying piece 5 for cooling the concrete. When the power mechanism 2 is powered on, the winding assembly 6 is unwound, the driving piece 3 is powered, the supporting assembly 4 and the spraying piece 5 are lifted, the use height of the spraying piece 5 is adjusted, the spraying piece 5 can reach high places through the splicing of the supporting pieces 41, the large volume concrete at high places is cooled, and after use, the supporting pieces 41 can be disassembled to reduce the transportation space.

[0033] Specifically, referring to Figure 2 The power mechanism 2 comprises two supporting frames 21 arranged above the bracket 1, two rotating shafts 22 penetrating through the two supporting frames 21 respectively, a gear 23 arranged at the right end of the right rotating shaft 22, and a servo motor 24 arranged at the left side of the left supporting frame 21, wherein the output end of the servo motor 24 is connected with the left rotating shaft 22.

[0034] Specifically, referring to Figure 3 The driving piece 3 comprises an internal threaded column 31 arranged on the bracket 1, a gear ring 32 rotatably arranged above the internal threaded column 31 and engaged with the gear 23, a driving ring 33 arranged on the inner wall of the gear ring 32, and two sliding blocks 34 arranged on the inner wall of the driving ring 33 respectively.

[0035] Specifically, referring to Figure 3 The supporting piece 41 comprises a lead screw 411, a threaded hole 412 formed in the upper end of the lead screw 411, a stud 413 arranged at the bottom end of the lead screw 411, two sliding grooves 414 formed in the outer wall of the lead screw 411, and the lead screw 411 penetrating through the internal threaded column 31 and the bracket 1 and being threadedly connected with the internal threaded column 31, and the sliding block 34 is slidable in the sliding groove 414.

[0036] In this embodiment, when the stud 413 on one lead screw 411 is inserted into the threaded hole 412 on another lead screw 411, the splicing between the two supporting pieces 41 can be achieved, and when disassembly is needed, the above steps are reversed.

[0037] When the gear ring 32 is rotated, the driving ring 33 is driven to rotate, and the lead screw 411 is driven to rotate through the cooperation between the sliding block 34 and the sliding groove 414. In this process, the lead screw 411 is lifted due to the threaded cooperation between the lead screw 411 and the inner wall of the internal threaded column 31, and the sliding block 34 is slid in the sliding groove 414 to maintain the driving state of the lead screw 411. Through the above steps, the lead screw 411 drives the spraying piece 5 to lift, so as to adjust the use height of the spraying piece 5.

[0038] Specifically, referring to Figure 4The spraying member 5 comprises a screw post 51 inserted into a threaded hole 412 of the uppermost screw rod 411, a mounting frame 52 rotatably arranged above the screw post 51, and a spraying frame 53 arranged on the outer wall of the mounting frame 52.

[0040] Specifically, referring to Figure 2 The winding assembly 6 comprises a rotary joint 61 arranged between the two rotating shafts 22 and a winding drum 62, which is hollow and in communication with the rotary joint 61. A conveying pipe 63 is wound on the outer wall of the winding drum 62, one end of which is in communication with the winding drum 62 and the other end is in communication with the spraying frame 53.

[0041] In the embodiment, when the servo motor 24 is powered on, it will first drive the rotating shaft 22 on one side to rotate, and at the same time drive the rotating shaft 22 on the other side and the gear 23 through the rotary joint 61 and the winding drum 62. Under the cooperation of the gear 23 and the gear ring 32, the gear ring 32 can be rotated to provide power for the lifting of the screw rod 411.

[0042] Before use, the rotary joint 61 needs to be connected with the external water pipe. When water is conveyed in the water pipe, it will first enter the rotary joint 61 and the winding drum 62, and then be transmitted to the spraying frame 53 through the conveying pipe 63 and sprayed out through the spraying frame 53.

[0043] When the rotary joint 61 rotates, the rotary joint 61 will still be connected with the external water pipe (prior art), and the winding drum 62 will pay off the conveying pipe 63 outward, so as to lengthen the outer edge length of the conveying pipe 63 when the spraying frame 53 rises.

[0044] Specifically, referring to Figure 4 The mounting frame 52 is provided with a guide member 7 on both sides of the outer wall thereof. The guide member 7 comprises a sleeve 71 arranged on the outer wall of the mounting frame 52, a plug rod 72 slidably inserted into the sleeve 71, a guide wheel 73 arranged at the end of the plug rod 72, and a fixing screw 74 arranged on the outer wall of the sleeve 71 and used for fixing the plug rod 72. One end of the fixing screw 74 is threaded through the sleeve 71 and abuts against the outer wall of the plug rod 72.

[0045] In the embodiment, before use, the guide wheel 73 needs to be adjusted to be in close contact with the concrete surface, and when the spraying piece 5 is lifted and lowered, the guide wheel 73 follows the concrete surface, and through the limiting of the two guide wheels 73, the deviation between the spraying angle and the concrete caused by the rotation of the mounting frame 52 following the lead screw 411 can be avoided, and the design that the inserting rod 72 can slide in the sleeve 71 can adjust the use position of the guide wheel 73, so that the guide wheel 73 can be adjusted when the distance between the device and the concrete changes, and the applicability is improved.

[0046] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
