Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a building concrete curing spray device. Background Technology

[0002] During the construction of buildings, concrete is usually used to pour walls. After pouring, the concrete walls need to be sprayed for curing to prevent the concrete surface from peeling off in flakes or powder. During the precast concrete stage of building construction, no other decoration is carried out inside the building. Therefore, the water source is not connected in high-rise buildings at this time, which leads to water supply difficulties in high-rise buildings and makes it inconvenient to cure the concrete walls in high-rise buildings.

[0003] According to patent application number 202323629146.6, entitled "A Concrete Spraying Curing Device for Building Construction," the patent includes a trolley with a water conveying mechanism on one side of its surface. A spraying mechanism is connected to the end of the water conveying mechanism, and a set of height adjustment mechanisms is attached to the surface of the spraying mechanism. The fixed end of the height adjustment mechanism is fixedly connected to the surface of the trolley, and an angle adjustment mechanism is provided inside the height adjustment mechanism. The spraying mechanism includes a collection frame positioned between the height adjustment mechanisms. This utility model allows the entire device to be moved to the desired high floor via the trolley. An external water source can then be connected to the water conveying mechanism via an external pipe to effectively deliver water to the high floor, solving the problem of water supply difficulties in high-rise buildings. Simultaneously, the spraying mechanism enables spraying curing of the concrete walls on high-rise buildings.

[0004] While the aforementioned patent solves the problem of water supply difficulties in high-rise buildings and achieves spray curing of concrete walls in high-rise buildings through a spraying mechanism, during the spray curing process, the water sprayed cannot be completely absorbed by the concrete wall, resulting in a large amount of excess water dripping down the wall. Since the concrete wall spray curing device cannot collect the dripping water, it leads to a significant waste of water resources during the spray curing process. Therefore, a building concrete curing spraying device is proposed to address the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A concrete curing spraying device includes a trolley, a water tank fixedly connected to the outside of the trolley, a tank cover screwed to the top of the outside of the water tank, a water pump connected to the bottom right side of the water tank, a folded pipe connected to the top of the water pump, a fixed sleeve connected to the other end of the folded pipe via a connecting pipe, a bracket rotatably connected to the outside of the fixed sleeve via a rotating shaft, a spray head connected to the right end of the fixed sleeve, a controller and a battery fixedly connected to the left side of the trolley in an up-down arrangement, a motor fixedly connected to the bottom right side of the trolley, a threaded shaft rotatably connected to the end of the motor's main shaft, a slider screwed to the outside of the threaded shaft and slidably connected to the trolley, a water collection tank in contact with the trolley fixedly connected to the bottom of the slider, a filter screen in contact with the bottom right side of the water collection tank, and a water pipe with an internal one-way valve connected to the bottom left side of the water collection tank, the other end of the water pipe being connected to the water tank.

[0007] As a further improvement of this utility model, a first electric push rod is rotatably connected to the left side of the bottom end of the fixed sleeve via a rotating shaft, and the other end of the first electric push rod is rotatably connected to the bracket via a rotating shaft. A second electric push rod that is fixedly connected to the trolley is fixedly connected to the bottom end of the bracket.

[0008] As a further improvement of this utility model, control switches are fixedly connected to both the left and right ends of the outer side of the slider, and one of the control switches is in contact with the trolley.

[0009] As a further improvement of this utility model, a pad is fixedly connected to the right end of the water collection tank, and the pad is made of rubber.

[0010] As a further improvement of this utility model, the bottom outer end of the water pipe is in contact with a guide wheel, and the guide wheel is rotatably connected to the trolley.

[0011] As a further improvement of this utility model, a support wheel is contacted at the top of the outer side of the water pipe, and a positioning frame that is slidably connected to the water tank is rotatably connected to the outer side of the support wheel via a rotating shaft. A spring is fixedly connected to the bottom end of the positioning frame, and the other end of the spring is fixedly connected to the water tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. A concrete curing spraying device, comprising a threaded shaft, a slider, a water collection tank, a water pump, a water pipe, and a filter screen, for spraying curing concrete walls, firstly, a motor drives the threaded shaft to connect with the slider in a spiral manner, further causing the slider to move the water collection tank out from the bottom of a trolley, then pushing the device to bring the pad at the right end of the water collection tank into contact with the wall surface. The device is then ready for use; at this time, water is drawn from the water tank by the water pump and discharged into a fixed sleeve through a folded pipe. The drawn water is then sprayed onto the concrete wall surface through the spray nozzles. Water dripping along the wall is continuously collected in a water collection tank. After being filtered through a filter, the collected water flows to the left side of the water collection tank. During this process, because the air pressure inside the water tank continues to decrease, the filtered water collected in the water collection tank is continuously returned to the water tank through a water pipe for reuse. When spraying and curing concrete walls, the water collection tank collects the water dripping along the wall, and then the collected water is filtered through a filter and returned to the water tank for reuse, thus avoiding a large waste of water resources.

[0013] 2. A concrete curing spraying device, which, through the installation of water pipes, support wheels, positioning frames, and springs, controls the water collection tank to move out from or return to the bottom of the trolley during use. The support wheels, under the elastic force of the springs on the positioning frames, always keep the water pipes tightly supported, preventing the water pipes from getting tangled. This ensures the normal recycling of collected water and the normal spraying curing of the concrete wall surface. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 like Figure 1-3 As shown, a concrete curing spraying device includes a trolley 1. A water tank 2 is fixedly connected to the outside of the trolley 1. A tank cover 3 is spirally connected to the top of the outside of the water tank 2. A water pump 4 is connected to the bottom right side of the water tank 2. A folded pipe 5 is connected to the top of the water pump 4. The other end of the folded pipe 5 is connected to a fixing sleeve 6 via a connecting pipe. A bracket 7 is rotatably connected to the outside of the fixing sleeve 6 via a rotating shaft. A spray head 8 is connected to the right end of the fixing sleeve 6. A controller 11 and a storage tank are fixedly connected to the left side of the trolley 1 in an up-down arrangement. The battery 12 is attached to the inner bottom right end of the trolley 1, and a motor 13 is fixedly connected to the end of the main shaft of the motor 13. A threaded shaft 14 is fixedly connected to the end of the main shaft of the motor 13 and is rotatably connected to the trolley 1. A slider 15 is screwed to the outside of the threaded shaft 14 and is slidably connected to the trolley 1. A water collection tank 16 is fixedly connected to the bottom end of the slider 15 and is in contact with the trolley 1. A filter screen 18 is in contact with the inner right end of the water collection tank 16. A water pipe 20 with a one-way valve is connected to the bottom left end of the water collection tank 16, and the other end of the water pipe 20 is connected to the water tank 2.

[0021] Example 2 like Figure 1-2As shown, to solve the problem of inconvenient adjustment of spray height and spray angle, a first electric push rod 9 is rotatably connected to the left side of the bottom end of the fixed sleeve 6 via a rotating shaft, and the other end of the first electric push rod 9 is rotatably connected to the bracket 7 via a rotating shaft. A second electric push rod 10 is fixedly connected to the bottom end of the bracket 7 and fixedly connected to the trolley 1. By controlling the extension and retraction of the second electric push rod 10, the bracket 7 drives the spray head 8 at the right end of the fixed sleeve 6 to move up and down, thereby adjusting the spray height. By controlling the extension and retraction of the first electric push rod 9, the fixed sleeve 6 drives the spray head 8 to rotate, thereby adjusting the spray angle.

[0022] Example 3 like Figure 2 As shown, in order to solve the problem that it is not convenient to automatically stop the motor 13 when the water collection tank 16 is moved out of or returned to the bottom of the trolley 1, control switches 17 are fixedly connected to both the left and right ends of the outer side of the slider 15, and one side of the control switch 17 is in contact with the trolley 1. During the process of starting the motor 13 and driving the threaded shaft 14 to be spirally connected to the slider 15 to control the water collection tank 16 to be moved out of or returned to the bottom of the trolley 1, the control switch 17 on the corresponding side is triggered by the slider 15, which facilitates the automatic control of stopping the motor 13.

[0023] Example 4 like Figure 1-3 As shown, in order to solve the problem of poor tightness between the water collection tank 16 and the wall, a pad 19 is fixedly connected to the right end of the water collection tank 16, and the pad 19 is made of rubber. By making the water collection tank 16 contact the wall through the rubber pad 19, the tightness between the water collection tank 16 and the wall is improved.

[0024] Example 5 like Figure 2 As shown, in order to solve the problem of excessive friction between the water pipe 20 and the trolley 1 when the water collection tank 16 pulls the water pipe 20, a guide wheel 21 is contacted at the bottom outer side of the water pipe 20, and the guide wheel 21 is rotatably connected to the trolley 1. When the water collection tank 16 pulls the water pipe 20, the guide wheel 21 guides the water pipe 20, which can avoid excessive friction between the water pipe 20 and the trolley 1.

[0025] Example 6 like Figure 1-2As shown, in order to solve the problem that the water pipe 20 may become tangled during the process of controlling the water collection tank 16 to move out from or return to the bottom of the trolley 1, the top of the outer side of the water pipe 20 is in contact with a support wheel 22. The outer side of the support wheel 22 is rotatably connected to a positioning frame 23 that is slidably connected to the water tank 2 via a rotating shaft. The bottom end of the positioning frame 23 is fixedly connected to a spring 24, and the other end of the spring 24 is fixedly connected to the water tank 2. During the process of controlling the water collection tank 16 to move out from or return to the bottom of the trolley 1, the support wheel 22 is always held tight by the elastic force of the spring 24 on the positioning frame 23, which can prevent the water pipe 20 from becoming tangled.

[0026] In this embodiment, when spraying and curing the concrete wall surface of a building using the device, after adding water to the water tank 2 and moving it to the designated usage position, the controller 11 first controls the motor 13 to drive the threaded shaft 14 to connect with the slider 15. At this time, the slider 15 will drive the water collection tank 16 to move out from the bottom of the trolley 1. When the water collection tank 16 is moved out, the slider 15 just triggers the control switch 17 on the right side, at which point the motor 13 will automatically stop. Then the device can be used. At this time, first push the device to move the water collection tank 16. The rubber pad 19 on the right side contacts the wall, and then the water pump 4 is started by the controller 11. The water pump 4 then draws water from the water tank 2 and discharges it through the folded pipe 5 into the fixed sleeve 6. The drawn water is sprayed onto the concrete wall through the sprinkler head 8 for spray curing. During this process, water dripping down the wall is continuously collected in the water collection tank 16. Finally, the collected water is filtered by the filter screen 18 and flows to the left side of the inner side of the water collection tank 16. During this process, because the air pressure inside the water tank 2 continues to decrease, at this time... The filtered water collected in the water collection tank 16 will continuously flow back to the water tank 2 through the water pipe 20 equipped with an internal one-way valve for reuse. During the spray curing of the building concrete wall, when it is necessary to adjust the spray height, the second electric push rod 10 is controlled to extend and retract, causing the bracket 7 to drive the spray head 8 at the right end of the fixed sleeve 6 to move up and down, thus adjusting the spray height. When it is necessary to adjust the spray angle, the first electric push rod 9 is controlled to extend and retract, causing the fixed sleeve 6 to drive the spray head 8 to rotate, thus adjusting the spray angle. When the use of the device is completed, the water collection tank 16 can be reset after the water pump 4 is stopped. During the use of the device, when the water collection tank 16 is moved out from the bottom of the cart 1 or reset to the bottom of the cart 1, the support wheel 22 is always held tightly by the spring force of the spring 24 on the positioning frame 23, thus avoiding the phenomenon of water pipe 20 getting tangled. This ensures the normal recycling of collected water and the normal spray curing of the concrete wall.
