Description

Technical Field

[0001] The present invention relates to the technical field related to building maintenance, and in particular to a spraying maintenance device for building concrete exterior wall construction. Background Art

[0002] During the construction of exterior concrete walls, spray curing plays a crucial role. It is key to ensuring concrete quality, effectively preventing cracks, and significantly improving concrete durability. By spraying the concrete surface uniformly, it provides an optimal humidity environment, promoting cement hydration and ensuring that the concrete achieves its desired strength and performance.

[0003] A search revealed that patent publication number 214834847U discloses a wall sprinkler device for construction. It uses a motor to adjust the height of the sprinkler pipe, a design that significantly changes the traditional spraying method. Previously, construction workers had to manually hold the sprinkler nozzle to spray, which was not only labor-intensive and inefficient, but also prone to uneven spraying. This device, however, uses a motor to adjust the height of the sprinkler pipe, avoiding waste of manpower and improving work efficiency while also enabling the pipe to spray at a uniform back-and-forth motion. This results in a more even spray across all parts of the wall, better meeting the requirements of concrete curing.

[0004] However, in actual use, for some high-altitude structures, the entire device must be placed near concrete for spraying operations, which clearly presents a certain level of difficulty. High-altitude working environments are complex and space is limited. Placing the large device in the appropriate location at high altitude is not easy, requiring not only increased manpower and material resources but also presents certain safety risks. Furthermore, the current device requires both a spray assembly and an up-and-down reciprocating assembly to achieve the spraying function. The presence of these two components makes the entire device relatively large, and requires numerous adjustment parts during the spraying process. This makes the entire device not only bulky but also difficult to carry and transport. On construction sites, the sprinkler system often needs to be moved and rearranged according to project progress and construction location changes. The large size and difficulty in carrying and transporting undoubtedly cause significant difficulties for construction workers and affect construction efficiency. Summary of the Invention

[0005] The present invention proposes a spray curing device for building concrete exterior wall construction, which adopts an assembled swing spray design and aims to effectively solve the problems of bulky spray systems and complex redundant transmission systems mentioned in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a spray maintenance equipment for the construction of building concrete exterior walls, comprising: a gear reduction motor fixed on the top of the wall, a top tube installed on the output shaft end, and the top tube, middle tube and bottom tube are fastened and connected in sequence; the sides of the top tube, middle tube and bottom tube are all provided with an atomizing nozzle facing the exterior wall concrete, and a water pipe is fixedly installed on the top of the top tube. After the water medium is transported to the inner cavity of the top tube, middle tube and bottom tube by the water pipe, the water medium can be sprayed onto the exterior wall concrete according to the atomizing nozzle; when the gear reduction motor drives the top tube to swing, the atomizing nozzle can evenly spray the exterior wall concrete.

[0007] Furthermore, there are multiple middle tubes.

[0008] Furthermore, a partition tube is fixedly installed at the bottom of the inner side of the bottom tube, and a movable sleeve is installed inside the partition tube to seal the movable sleeve; a tension spring is connected between the partition tube and the movable sleeve; and a second atomizing nozzle is provided on the side of the movable sleeve.

[0009] Furthermore, the end of the movable sleeve is elliptical in shape, and a vertical wheel is fastened to the bottom.

[0010] Furthermore, an adjusting cylinder is fixedly installed on the bottom of the outer side of the bottom cylinder, and a switching piston is movably installed in the adjusting cylinder, and a transverse wheel is movably installed on the end of the switching piston.

[0011] Furthermore, a driving gear is coaxially fastened to the output end of the gear reduction motor, and a gear sleeve that cooperates with the driving gear is sleeved on the output end of the gear reduction motor, and the top cylinder is fixedly installed with the gear sleeve.

[0012] Furthermore, a liquid infusion tube connected to the bottom cylinder is fixedly installed on the side of the adjusting cylinder, a reset push spring is connected between the adjusting cylinder and the switching piston, a fan pump is movably installed at the end of the adjusting cylinder, and the pump blades in the fan pump are coaxially fastened with the horizontal rotating shaft, the input end of the fan pump is connected to the inner cavity of the adjusting cylinder, and the output end is fixedly installed with a connecting pipe connected to the partition cylinder.

[0013] Furthermore, a fluid infusion pipe communicating with the regulating cylinder is fixedly installed on the side of the communicating pipe, and a one-way valve is provided in the fluid infusion pipe.

[0014] The present invention has the following beneficial effects: The present invention provides a spray maintenance equipment for the construction of building concrete exterior walls. The equipment is installed on the top of the concrete wall through a gear reduction motor, and the output shaft of the gear reduction motor is used to drive the hollow cylinder to perform a 90-degree reciprocating deflection motion. During this process, the hollow cylinder not only serves as a transmission component, but also uses a water pipe to transport the water medium into the hollow cylinder, so that the water medium can be sprayed toward the concrete wall from the atomizing nozzle arranged outside the hollow cylinder, thereby achieving uniform spraying of the concrete wall.

[0015] Not only that, the hollow cylinder is composed of a top cylinder, a middle cylinder and a bottom cylinder. There are multiple middle cylinders. The detachable installation between the middle cylinder and the top cylinder and the bottom cylinder not only facilitates the overall transportation, but also adjusts the number of middle cylinders used according to concrete walls of different heights, ensuring that the hollow cylinder is easy to transport and can adapt to the spraying work of walls of different heights.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] For example 1, please refer to Figure 1It can be seen that the power in this application is mainly provided by the gear reduction motor 1. When in use, it is only necessary to use a bracket to fix the gear reduction motor 1 on the top of the wall to be sprayed, and then connect the spray cylinder to the output end of the gear reduction motor 1 to realize the spraying of water medium onto the exterior wall concrete.

[0021] More specifically, from Figure 1 It can be clearly seen that a top tube 4 is mounted on the output end of the gear reduction motor 1. A middle tube 6 is fastened to the bottom of the top tube 4 via a flange. At the same time, a bottom tube 7 is also fastened to the bottom of the middle tube 6 via a flange. The top tube 4, middle tube 6, and bottom tube 7 together form a set of equipment capable of spraying exterior wall concrete. Atomizing nozzles 5 facing the exterior wall concrete are equidistantly arranged on the sides of the top tube 4, middle tube 6, and bottom tube 7. A water medium is fed into the water pipe 400 fixedly mounted on the top of the top tube 4, and the water medium is pumped into the water pipe 400 using a water pump. Since the inner cavities of the top tube 4, middle tube 6, and bottom tube 7 are interconnected, once the water medium is fed into the water pipe 400, it is sprayed into the exterior wall concrete through the atomizing nozzle 5. In combination with the above, the top tube 4 is installed at the output shaft end of the gear reduction motor 1. During the actual spraying process, it is only necessary to fix the gear reduction motor 1 at the corner of one side of the outer wall, and use the gear reduction motor 1 to drive the top tube 4 to perform periodic 90-degree reciprocating swings, thereby ensuring that the atomizing nozzle 5 on the top tube 4, the middle tube 6 and the bottom tube 7 can evenly spray the outer wall concrete.

[0022] From this, it can be seen that the top tube 4, middle tube 6 and bottom tube 7 in this application not only use themselves for transmission at the application level, but also use the water medium inside them to spray from the atomizing nozzle 5, so that the atomizing nozzle 5 can evenly spray the exterior wall concrete. Ultimately, the transmission and spraying structure are integrated into one, greatly simplifying the overall structure. In addition, since the gear reduction motor 1 is directly installed on the exterior wall, the solution proposed in this application is still applicable even in the spraying of the exterior walls of high-rise buildings. Compared with traditional spraying, the gear reduction motor 1 is installed on the top of the exterior wall, which is more convenient for operators to install it.

[0023] During transport and assembly, the top tube 4, middle tube 6, and bottom tube 7 can be disassembled and transported separately. Generally, there is only one top tube 4 and one bottom tube 7, but there are multiple middle tubes 6. In actual use, the spray range can be controlled by only determining the actual number of middle tubes 6 used.

[0024] The second embodiment is a further improvement on the first embodiment. Figure 1 、 Figure 3 and Figure 6It can be seen that a partition tube 12 is fixedly installed at the bottom of the inner side of the bottom tube 7, and a movable sleeve 8 extending from the bottom of the bottom tube 7 is sealed inside the partition tube 12. Since the end of the movable sleeve 8 is elliptical, the movable sleeve 8 is limited to reciprocating up and down along the partition tube 12. A tension spring 13 is connected between the partition tube 12 and the movable sleeve 8. Under normal circumstances, the elastic contraction of the tension spring 13 forces the movable sleeve 8 to retract to the inside of the partition tube 12. Atomizing nozzles 800 are equidistantly arranged on the side of the movable sleeve 8. In this embodiment, the inner cavity of the partition tube 12 can be directly connected to the inner cavity of the bottom tube 7. Therefore, after the water pipe 400 transports the water medium into the inner cavity of the bottom tube 7, the water pressure is used to extend the movable sleeve 8 outward, forcing the movable sleeve 8 to drive the atomizing nozzle 800 to extend from the partition tube 12. Since the water medium in the inner cavity of the movable sleeve 8 can be sprayed out from the second atomizing nozzle 800, the extension of the movable sleeve 8 can extend the spraying range, thereby avoiding the problem of spraying dead angles caused by the fan-shaped method used in the first embodiment.

[0025] On this basis, vertical wheels 11 are fastened to the bottom of the movable sleeve 8. When the bottom of the exterior wall is aligned with the ground, the movable sleeve 8 is extended to ensure comprehensive spraying of the exterior wall. Moreover, when the vertical wheels 11 are close to the ground, the downward movement of the movable sleeve 8 is restricted, preventing the movable sleeve 8 from excessively descending and causing direct contact with the ground.

[0026] Example 3 is a further improvement of Example 2. Figure 3 and Figure 4 As can be seen, an adjustment cylinder 9 is fixedly mounted on the outer bottom of the bottom barrel 7, with a switching piston 16 movably mounted in the adjustment cylinder 9. A transverse wheel 10, perpendicular to the vertical wheel 11, is movably mounted on the end of the switching piston 16. When the transverse wheel 10 is pressed against the exterior wall concrete, it limits the distance between the atomizing nozzle 5 and the concrete exterior wall, ensuring an optimal spray distance between the atomizing nozzle 5 and the concrete exterior wall.

[0027] For specific installation adjustments, Figure 2 As can be seen in the figure, the output end of the gear reduction motor 1 is coaxially fixed with a drive gear 2, and a gear sleeve 3 is mounted on this output end, which cooperates with the drive gear 2 and is limited in position by a nut. Because the top tube 4 and gear sleeve 3 are fixedly mounted, axial adjustment of the gear sleeve 3 along the output shaft of the gear reduction motor 1 can control the actual distance between the top tube 4, middle tube 6, and bottom tube 7 and the exterior wall concrete, until the transverse wheels 10 on the bottom tube 7 are pressed tightly against the exterior wall concrete, achieving the optimal position.

[0028] On the basis of the above, combined with Figure 1 、 Figure 3 and Figure 4It can be seen that a liquid infusion tube 14 is fixedly installed on the side of the regulating cylinder 9, and the liquid infusion tube 14 is used to connect the inner cavity of the regulating cylinder 9 and the inner cavity of the bottom tube 7. A reset spring 160 is connected between the regulating cylinder 9 and the switching piston 16. Under normal circumstances, the reset spring 160 has a tendency to push the switching piston 16 to block the liquid infusion tube 14 due to its elastic force, and as the switching piston 16 drives the transverse wheel 10 to move, it forces the transverse wheel 10 to move relatively away from the regulating cylinder 9. A fan pump 17 is movably installed at the end of the regulating cylinder 9, and the pump blades in the fan pump 17 are coaxially fastened with the rotating shaft of the transverse wheel 10, so that the pump blades in the fan pump 17 can rotate with the transverse wheel 10. The input end of the fan pump 17 is connected to the inner cavity of the regulating cylinder 9, and the output end is fixedly installed with a connecting pipe 15. The connecting pipe 15 passes through the bottom tube 7 and is connected to the inner cavity of the partition tube 12. It should be noted that the partition tube 12 in this embodiment 3 is only connected to the inner cavity of the fan pump 17 by the connecting pipe 15. Not only that, a fluid infusion tube 150 is fixedly installed on the side of the connecting tube 15, and the fluid infusion tube 150 is fixed on the side of the regulating cylinder 9. The fluid infusion tube 150 is used to connect the inner cavity of the regulating cylinder 9 and the connecting tube 15. Not only that, a one-way valve is provided in the fluid infusion tube 150, thereby limiting the water medium in the inner cavity of the regulating cylinder 9 to only be transported in one direction from the fluid infusion tube 150 to the connecting tube 15.

[0029] In actual application, the position of the gear sleeve 3 is adjusted axially along the output end of the gear reduction motor 1, forcing the transverse wheel 10 to reach the outer wall concrete, and the reset spring 160 is compressed, and the switching piston 16 is relatively away from the infusion tube 14. At this time, the infusion tube 14 and the inner cavity of the regulating cylinder 9 are connected.

[0030] 1. When the exterior wall concrete is aligned with the ground, initially, the movable sleeve 8 is pulled back into the inner cavity of the partition tube 12 by the elastic force of the tension spring 13, and the vertical wheel 11 is also relatively far away from the ground. When spraying is required, a water pump is used to transport the water medium from the water pipe 400 to the inner cavities of the top tube 4, the middle tube 6 and the bottom tube 7. After the water medium in the bottom tube 7 passes through the liquid delivery pipe 14, the inner cavity of the regulating cylinder 9 and the liquid replenishing pipe 150, it is transported to the inner cavity of the partition tube 12 by the connecting pipe 15. As the water medium in the inner cavity of the partition tube 12 increases, the movable sleeve 8 is forced to be pushed outward until the vertical wheel 11 reaches the ground. At this time, the extension of the movable sleeve 8 enables the device to fully spray the exterior wall concrete.

[0031] As the gear reduction motor 1 drives the top cylinder 4 to deflect counterclockwise, the direction is as follows Figure 1 As shown, the top tube 4, the middle tube 6 and the bottom tube 7 will also start to deflect. During this process, as the movable sleeve 8 continues to extend, the area swept by the bottom tube 7 and the movable sleeve 8 can be fully sprayed on the bottom of the outer wall to avoid the occurrence of spraying dead angles during fan-shaped movement. Figure 6 The blind spot range of position A is shown.

[0032] If during this process, when the horizontal wheel 10 moves to Figure 6 When the switch piston 16 is at the side edge of the middle position B, the elastic force of the return spring 160 causes the switch piston 16 to drive the transverse wheel 10 relatively away from the adjustment cylinder 9 until the switch piston 16 blocks the infusion tube 14. At this time, the medium in the infusion tube 14 cannot be transported into the inner cavity of the partition tube 12, and the movable sleeve 8 tends to be retracted into the partition tube 12 due to the elastic force of the tension spring 13. This method not only prevents the movable sleeve 8 from being overextended, but also prevents the movable sleeve 8 from spraying unnecessary areas.

[0033] When the gear reduction motor 1 stalls, Figure 1 and Figure 4 It can be seen that when the bottom cylinder 7 deflects upward, the transverse wheel 10 contacts the outer wall and drives the impeller pump 17 to rotate. At this time, the impeller pump 17 transports the medium in the connecting pipe 15 to the inner cavity of the regulating cylinder 9. However, due to the increase in pressure in the inner cavity of the regulating cylinder 9, the medium in the inner cavity of the regulating cylinder 9 will be transported to the connecting pipe 15 again according to the infusion pipe 150. After the stall, the bottom cylinder 7 tends to deflect rapidly toward the ground, the vertical wheel 11 contacts the ground and causes the movable sleeve 8 to be quickly retracted into the partition cylinder 12. The water medium in the inner cavity of the partition cylinder 12 cannot be compressed in a short time. Therefore, when the movable sleeve 8 is quickly retracted into the partition cylinder 12, the water medium pressure in the inner cavity of the partition cylinder 12 will increase. When the medium in the partition cylinder 12 flows from the impeller pump 17 through the connecting pipe 15, the rotation direction of the impeller pump 17 is opposite to the water flow direction. Therefore, the medium pressure in the connecting pipe 15 is opposite to the rotation direction of the impeller pump 17, forcing the movement resistance of the transverse wheel 10 to increase. Combined with the close contact between the transverse wheel 10 and the outer wall, the resistance of the transverse wheel 10 is increased, so that the bottom cylinder 7 can buffer and slow down after the stall.

[0034] 2. When spraying concrete on high-altitude exterior walls, the spraying method is the same as the above. However, when spraying on high-altitude exterior walls, if stall occurs, the bottom cylinder 7 will deflect clockwise downward along the gear reduction motor 1, and the direction reference Figure 1 and Figure 6, the transverse wheel 10 drives the vane pump 17 to rotate rapidly, and the vane pump 17 will quickly transport the medium in the inner cavity of the regulating cylinder 9 to the connecting pipe 15. However, unlike the above, because the bottom cylinder 7 is in the air, the movable sleeve 8 has already extended to the limit from the partition cylinder 12. Therefore, as the vane pump 17 further intensifies the delivery of medium to the connecting pipe 15, the medium pressure in the partition cylinder 12 will increase. Correspondingly, the movement resistance of the vane pump 17 also increases relatively, forcing the transverse wheel 10 to drive the vane pump 17 to increase its resistance. Therefore, it can be seen that when the gear reduction motor 1 stalls during high-altitude exterior wall spraying, the vane pump 17 is used to intensify the delivery of medium to the connecting pipe 15, forcing the medium pressure in the inner cavity of the partition cylinder 12 to rise, and ultimately the movement resistance fed back to the vane pump 17 increases sharply, thereby reducing the movement speed of the transverse wheel 10. Therefore, when the transverse wheel 10 decelerates, it can tend to reduce the speed of the top cylinder 4, middle cylinder 6, and bottom cylinder 7.
