A rotary spray device for concrete temperature control

Abstract

This utility model relates to the technical field of concrete temperature control devices, and in particular to a rotary spraying device for concrete temperature control. It includes a support frame, within which a cross seat is fitted. Multiple connecting rods are located within the support frame, with ball heads fixedly connected to the ends of the connecting rods. The ball heads at the ends of the connecting rods are rotatably connected to the cross seat. A spraying assembly is mounted on the other end of each connecting rod. A rotating frame is slidably connected to the outer wall of the connecting rods, with both ends of the rotating frame rotatably connected to the support frame. A screw is rotatably connected to the inner wall of the cross seat. In this device, rotating a knob drives the screw to rotate. Since the screw sleeve is fixed to the support rod and cannot rotate, the screw drives the cross seat to rise and fall axially. When the cross seat rises and falls, the ball heads push the connecting rods to rotate around the rotating frame, thus adjusting the tilt angle of the spraying assembly to adapt to concrete components placed in different positions. This ensures that the entire area where the concrete component is placed is sprayed, completely solving the problem of incomplete coverage in traditional devices.

Description

Technical Field

[0001] This utility model relates to the technical field of concrete temperature control devices, and more specifically, to a rotary spray device for concrete temperature control. Background Technology

[0002] Temperature control is a key aspect of ensuring the strength and durability of concrete during construction, especially for large-volume concrete or construction in high- or low-temperature environments, where spraying is used to regulate temperature and prevent cracks from forming.

[0003] Existing concrete temperature-controlled spraying devices use fixed nozzles or a single-direction rotating structure, limiting the spraying range to a specific area. They cannot be adjusted according to the location of concrete components, making it difficult to fully cover the area where the concrete components are placed. Utility Model Content

[0004] Based on the aforementioned technical problem that "traditional concrete temperature control spraying devices have limited spraying range due to the use of fixed nozzles or unidirectional rotation structures, and cannot be adjusted according to the position of concrete components, resulting in incomplete coverage," this utility model proposes a rotary spraying device for concrete temperature control.

[0005] This utility model discloses a rotary spraying device for concrete temperature control, comprising a support frame, a cross seat fitted inside the support frame, multiple connecting rods inside the support frame, a ball head fixedly connected to the end of each connecting rod, the ball head rotatably connected to the cross seat, a spraying assembly mounted on the other end of each connecting rod, a rotating frame slidably connected to the outer wall of each connecting rod, both ends of the rotating frame being rotatably connected to the support frame, a screw rotatably connected to the inner wall of the cross seat, a knob fixedly connected to the top of the screw, a threaded sleeve threadedly connected to the outer wall of the screw, a support rod fixedly connected to the outer wall of the threaded sleeve, and an end of the support rod fixedly connected to the support frame.

[0006] Preferably, the spray assembly includes a connecting sleeve, which is fixedly connected to the connecting rod, and the outer wall of the connecting sleeve has a through hole.

[0007] Preferably, the spray assembly further includes a spray head, the end of which is fixedly connected to a connecting sleeve, and the through hole is connected to the water inlet of the spray head.

[0008] Preferably, the rotary spray device further includes a mounting frame, on the outer wall of which a stepper motor is fixedly connected, and on the output end of the stepper motor is a fixedly connected output shaft, and on the outer wall of the output shaft are gears fixedly connected.

[0009] Preferably, a mounting sleeve is fixedly connected to the outer wall of the mounting bracket, a rotating sleeve is rotatably connected to the inner wall of the mounting sleeve, and a gear ring is fixedly connected to the outer wall of the rotating sleeve, the gear ring meshing with a gear.

[0010] Preferably, a connecting plate is fixedly connected to the top of the rotating sleeve by bolts, a filter cylinder is fixedly connected to the inner wall of the connecting plate, and a water inlet pipe is fixedly connected to the bottom of the filter cylinder.

[0011] Preferably, a pressure pump is fixedly connected to the top of the filter cartridge, the water inlet of the pressure pump is connected to the filter cartridge through a connecting pipe, and the water outlet of the pressure pump is connected to the water inlet of multiple spray heads through a connecting pipe.

[0012] Preferably, a rotating ring is rotatably connected to the outer wall of the support frame, and the rotating ring is fixedly connected to the mounting frame.

[0013] The beneficial effects of this utility model, achieved through the above technical solution, are as follows: 1. Rotating the knob drives the screw to rotate. Since the screw sleeve is fixed to the support rod, it cannot rotate. Therefore, the screw drives the cross seat to rise and fall axially. When the cross seat rises and falls, the ball head pushes the connecting rod to rotate around the rotating frame, thereby adjusting the tilt angle of the spray assembly to adapt to concrete components in different placement positions. This ensures that the entire area where the concrete components are placed is sprayed, completely solving the problem of incomplete coverage by traditional devices.

[0014] 2. The rotating ring reduces rotational friction between the support frame and the mounting frame, ensuring smooth overall rotation; at the same time, it provides radial positioning for the support frame, preventing the spray head from shifting due to shaking during rotation, ensuring spraying accuracy, and improving the stability of the device.

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model. In this utility model, unless otherwise expressly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figures 3-5 As shown, a rotary spraying device for concrete temperature control includes a support frame 11, a cross seat 17 is fitted inside the support frame 11, and multiple connecting rods 23 are provided inside the support frame 11. A ball head 24 is fixedly connected to the end of the connecting rod 23, and the ball head 24 at the end of the connecting rod 23 is rotatably connected to the cross seat 17. A spraying assembly is installed at the other end of the connecting rod 23. A rotating frame 22 is slidably connected to the outer wall of the connecting rod 23. Both ends of the rotating frame 22 are rotatably connected to the support frame 11. A screw 15 is rotatably connected to the inner wall of the cross seat 17. A knob 16 is fixedly connected to the top of the screw 15. A threaded sleeve 13 is threadedly connected to the outer wall of the screw 15. A support rod 14 is fixedly connected to the outer wall of the threaded sleeve 13, and the end of the support rod 14 is fixedly connected to the support frame 11.

[0019] The spray assembly can be adjusted at multiple angles by connecting the ball joint of the connecting rod 23 and the cross seat 17 and by supporting the rotating frame 22. The engagement of screw 15 and screw sleeve 13 can control the tilt angle of the connecting rod, solving the problem of limited coverage of traditional fixed or single-direction spraying devices and ensuring that all areas of the concrete component can be sprayed. The through hole 21 of the connecting sleeve 20 ensures that water flows steadily into the spray head 19, improving the uniformity of spraying.

[0020] The spray assembly includes a connecting sleeve 20, which is fixedly connected to the connecting rod 23. The outer wall of the connecting sleeve 20 has a through hole 21.

[0021] The spray assembly also includes a spray head 19, the end of which is fixedly connected to the connecting sleeve 20, and the through hole 21 is connected to the water inlet of the spray head 19.

[0022] like Figure 1 and Figure 2 As shown, the rotary spray device also includes a mounting frame 1, a stepper motor 2 is fixedly connected to the outer wall of the mounting frame 1, an output shaft 3 is fixedly connected to the output end of the stepper motor 2, and a gear 4 is fixedly connected to the outer wall of the output shaft 3.

[0023] Mounting bracket 1 has a mounting sleeve 5 fixedly connected to its outer wall, a rotating sleeve 6 rotatably connected to the inner wall of mounting sleeve 5, and a gear ring 7 fixedly connected to the outer wall of rotating sleeve 6, which meshes with gear 4.

[0024] The top of the rotating sleeve 6 is fixedly connected to the connecting plate 8 by bolts. The inner wall of the connecting plate 8 is fixedly connected to the filter cylinder 9. The bottom of the filter cylinder 9 is fixedly connected to the water inlet pipe 10.

[0025] A pressure pump 12 is fixedly connected to the top of the filter cartridge 9. The water inlet of the pressure pump 12 is connected to the filter cartridge 9 through a connecting pipe, and the drain of the pressure pump 12 is connected to the water inlet of multiple spray heads 19 through a connecting pipe.

[0026] Stepper motor 2 drives rotating sleeve 6 to rotate via gear 4 and gear ring 7, realizing 360° rotation of the entire spraying device and expanding the horizontal spraying range; filter cylinder 9 filters impurities and prevents spray head 19 from clogging; pressure pump 12 provides stable water pressure to ensure that the spraying intensity meets the temperature regulation requirements of concrete and adapts to the spraying pressure requirements of different components.

[0027] like Figure 1 As shown, a rotating ring 18 is rotatably connected to the outer wall of the support frame 11, and the rotating ring 18 is fixedly connected to the mounting frame 1.

[0028] The rotating ring 18 reduces the rotational friction between the support frame 11 and the mounting frame 1, ensuring smooth overall rotation; at the same time, it plays a radial positioning role for the support frame 11, preventing the spray head 19 from shifting due to shaking during rotation, ensuring spraying accuracy and improving the stability of the device.

[0029] Working principle: During use, the stepper motor 2 drives the gear 4 to rotate through the output shaft 3. The gear 4 drives the rotating sleeve 6 to rotate inside the mounting sleeve 5 through meshing with the gear ring 7, thereby driving the support frame 11 to rotate as a whole, achieving 360° rotation coverage in the spray direction.

[0030] Rotating knob 16 causes screw 15 to rotate. Screw sleeve 13 cannot rotate because it is fixed to support rod 14. Therefore, screw 15 drives cross seat 17 to rise and fall axially. When cross seat 17 rises and falls, ball head 24 pushes connecting rod 23 to rotate around rotating frame 22, adjusting the tilt angle of spray head 19.

[0031] The pressure pump 12 pressurizes the water in the filter cylinder 9 and then delivers it to the connecting sleeve 20 through the connecting pipe. The water then enters the spray head 19 through the through hole 21 and is finally sprayed onto the surface of the concrete component.

[0032] The rotating ring 18 ensures a stable connection between the support frame 11 and the mounting frame 1 when the support frame 11 rotates, and the filter cartridge 9 filters impurities in the water to prevent the spray head from clogging.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
