Description

Technical Field

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

[0002] If the weather is hot and the air is dry after concrete pouring, and curing is not carried out promptly, the moisture in the concrete will evaporate too quickly, leading to dehydration. This will prevent the cement particles, which have already formed a gel, from fully hydrating and transforming into stable crystals, resulting in insufficient bonding strength and causing flaking or powdering on the concrete surface. Furthermore, premature evaporation of moisture before the concrete has reached sufficient strength can also cause significant shrinkage deformation, leading to drying shrinkage cracks. Therefore, curing in the initial stage after concrete pouring is crucial. Curing should begin immediately after the concrete has set, and dry-hard concrete should be cured immediately after pouring.

[0003] Traditional concrete curing methods (such as manual watering and covering with a moisture-retaining film) have problems such as low efficiency, uneven coverage, and high labor intensity. They are especially difficult to maintain for vertical walls or large-volume concrete structures.

[0004] Currently, there are some concrete curing devices on the market, such as those using mobile carts equipped with spray systems for automated curing. However, existing technologies still have the following shortcomings: most devices can only spray concrete structures from one side, and cannot simultaneously cure both sides of the wall, resulting in low curing efficiency and easy impact on concrete quality due to uneven water penetration; the spray components are mostly fixed designs, making it impossible to quickly adjust the angle or disassemble and replace them according to construction needs, affecting the ease of operation.

[0005] Therefore, a concrete curing device is proposed. Utility Model Content

[0006] This utility model is a concrete curing device proposed to overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a concrete curing device, including a mobile trolley, wherein a water storage tank is fixedly installed on one side of the top of the mobile trolley;

[0008] A bracket is fixedly installed on one side of the top of the mobile trolley, and a manual lifting component is installed on the bracket. The movable end of the manual lifting component is fixedly connected to a housing.

[0009] The housing is equipped with a rotating component, and a support frame is fixedly installed on the movable end of the rotating component.

[0010] The support frame is equipped with a manual distance adjustment component. The bottom of the support frame and the bottom of the movable end of the manual distance adjustment component are both fixedly connected to a connecting pipe. Multiple straight pipes are provided below the two connecting pipes. The bottom of the two connecting pipes and the bottom of the multiple straight pipes are both fixedly connected to a threaded pipe. The multiple straight pipes are all sealed and threadedly connected to the threaded pipe at their top. Multiple nozzles are fixedly passed through the outer surface of the multiple straight pipes.

[0011] Both of the aforementioned connecting pipes are connected to a pumping assembly between them and the water storage tank.

[0012] Furthermore, the top opening of the water storage tank is threaded with a lid, which ensures the water storage tank is airtight, prevents debris from entering or water from evaporating, and facilitates quick disassembly for cleaning or water replenishment.

[0013] Furthermore, the manual lifting assembly includes a first handwheel, which is located inside the bracket. A first screw is fixedly connected to the top of the first handwheel and passes through the bracket, and is rotatably connected to the bracket. A slide is threaded onto the outer surface of the first screw, and the slide is slidably connected to the bracket and fixedly connected to the housing. The screw drive structure makes operation labor-saving and lifting smooth, and the spray height can be adjusted.

[0014] Furthermore, the rotating assembly includes a motor, which is fixedly mounted on one side of the outer surface of the housing. A worm is fixedly connected to the drive end of the motor, and the worm passes through the housing and is rotatably connected thereto. A worm wheel is meshed with the outer surface of the worm, and the mounting shaft of the worm wheel passes through the housing and is rotatably connected to the housing. The mounting shaft of the worm wheel is fixedly connected to the support frame. The worm gear transmission has a self-locking characteristic, which can stably maintain the rotation angle of the support frame.

[0015] Furthermore, the manual spacing adjustment component includes a second handwheel, which is located at one end of the support frame. The drive end of the second handwheel is fixedly connected to a second screw, which passes through the support frame and is rotatably connected to it. A slider is threaded onto the outer surface of the second screw, which is slidably connected to the support frame and fixedly connected to the adjacent connecting pipe. The spacing between the two spray pipes can be adjusted by the screw drive to adapt to concrete walls of different thicknesses.

[0016] Furthermore, the outer surfaces of the two bottom threaded tubes are sealed with end caps. The end caps are designed to prevent water leakage from unused threaded tubes and facilitate subsequent expansion of the spray pipe length.

[0017] Furthermore, the pumping assembly includes a water pump, which is fixedly installed on the top of the mobile trolley. The input end of the water pump is fixedly connected to the water storage tank, and the output end of the water pump is fixedly connected to a diverter. Both top ports of the diverter are fixedly connected to flexible hoses, which are also fixedly connected to a connecting pipe. The outer surfaces of the two flexible hoses are fitted with a limiting frame, which is fixedly installed on one side of the slide. The diverter enables dual-path water supply, ensuring balanced spray pressure on both sides. The flexible hoses, in conjunction with the limiting frame, prevent pipe entanglement.

[0018] Furthermore, a heat dissipation shell is fixedly installed on one side of the top of the mobile trolley.

[0019] The beneficial effects of this utility model are:

[0020] In use, this concrete curing device allows for the adjustment of the support frame's angle via a rotating component, enabling the straight pipes on both sides to be quickly positioned on either side of the concrete wall for simultaneous double-sided spray curing. Compared to traditional single-sided curing methods, this structure significantly improves the curing efficiency and the uniformity of moisture penetration in concrete walls. Furthermore, the spray height can be adjusted via a manual lifting component, and the distance between the two sets of nozzles can be adjusted using a spacing adjustment component, allowing the device to adapt to concrete structures of varying heights and thicknesses. The detachable straight pipes and nozzles facilitate adjustment of the spray range, making curing operations more flexible and efficient. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 3 As shown, a concrete curing device is disclosed, including a mobile trolley 1. A water storage tank 5 is fixedly installed on one side of the top of the mobile trolley 1. A cover 7 is threadedly connected to the top opening of the water storage tank 5. The mobile trolley 1 is welded from high-strength steel and equipped with four universal wheels (with brake devices) at the bottom for easy movement and positioning on the construction site.

[0029] A bracket 8 is fixedly installed on one side of the top of the mobile trolley 1. A manual lifting assembly is installed on the bracket 8. The movable end of the manual lifting assembly is fixedly connected to the housing 12. The manual lifting assembly includes a first handwheel 15, which is located inside the bracket 8. A first screw 14 is fixedly connected to the top of the first handwheel 15 and passes through the bracket 8, and is rotatably connected to the bracket 8. A slide block 11 is threaded onto the outer surface of the first screw 14, and the slide block 11 is slidably connected to the bracket 8 and fixedly connected to the housing 12. The helix angle of the first screw 14 is smaller than the friction angle, so that the first screw 14 has a self-locking capability and can prevent it from shifting due to vibration or load.

[0030] The housing 12 is equipped with a rotating assembly, and a support frame 17 is fixedly installed on the movable end of the rotating assembly. The rotating assembly includes a motor 16, which is fixedly installed on one side of the outer surface of the housing 12. A worm gear 10 is fixedly connected to the drive end of the motor 16, and the worm gear 10 passes through the housing 12 and is rotatably connected thereto. A worm wheel 25 is meshed with the outer surface of the worm gear 10, and the mounting shaft of the worm wheel 25 passes through the housing 12 and is rotatably connected thereto. The mounting shaft of the worm wheel 25 is fixedly connected to the support frame 17.

[0031] The support frame 17 is equipped with a manual adjustment component. The bottom of the support frame 17 and the bottom of the movable end of the manual adjustment component are both fixedly connected to a connecting pipe 21. The manual adjustment component includes a second handwheel 20, which is located at one end of the support frame 17. The driving end of the second handwheel 20 is fixedly connected to a second screw 18, which passes through the support frame 17 and is rotatably connected to it. A slider 19 is threaded onto the outer surface of the second screw 18, and the slider 19 is slidably connected to the support frame 17 and fixedly connected to the adjacent connecting pipe 21. The helix angle of the second screw 18 is smaller than the friction angle, which gives the second screw 18 a self-locking capability, preventing it from shifting due to vibration or load.

[0032] Below each of the two connecting pipes 21, there are multiple straight pipes 13. The bottom of each of the two connecting pipes 21 and the bottom of the multiple straight pipes 13 are fixedly connected to threaded pipes 22, and the multiple straight pipes 13 are all sealed threadedly connected to their top threaded pipes 22. Multiple nozzles 23 are fixedly passed through the outer surface of each of the multiple straight pipes 13, and end caps 24 are sealed threadedly fitted onto the outer surface of the two bottom threaded pipes 22.

[0033] Both connecting pipes 21 are connected to the water storage tank 5 by a pumping assembly, which includes a water pump 2. The water pump 2 is fixedly installed on the top of the mobile trolley 1. The input end of the water pump 2 is fixedly connected to the water storage tank 5. The output end of the water pump 2 is fixedly connected to a distributor 3. The top two ports of the distributor 3 are fixedly connected to hoses 6, and the hoses 6 are fixedly connected to the connecting pipes 21. The outer surfaces of the two hoses 6 are fitted with a limiting frame 9, and the limiting frame 9 is fixedly installed on one side of the slide 11.

[0034] A heat dissipation shell 4 is fixedly installed on one side of the top of the mobile trolley 1. An existing battery and controller are installed inside the heat dissipation shell 4. The controller is electrically connected to the battery, water pump 2, and motor 16 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge, and these methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that this hardware structure improvement can achieve, based on common knowledge. Simultaneously, a PTFE waterproof and breathable membrane is covered inside the heat dissipation holes of the heat dissipation shell 4, allowing air circulation but blocking liquid water penetration, ensuring heat dissipation of internal electrical components while providing splash protection.

[0035] Working principle: The mobile trolley 1 can be moved flexibly to the vicinity of the concrete wall to be cured, which facilitates the curing operation in the construction area;

[0036] The water storage tank 5 is used to store maintenance water, and its top is equipped with a threaded cover 7 for easy water addition or cleaning.

[0037] Rotating the first handwheel 15 drives the first screw 14 to rotate, causing the slide block 11 to slide up and down along the bracket 8, thereby driving the housing 12 and the spraying mechanism to rise and fall to adapt to concrete structures of different heights.

[0038] Rotating the second handwheel 20 drives the second screw 18 to rotate, causing the slider 19 to slide along the support frame 17, thereby adjusting the position of the connecting pipe 21 on one side and changing the spacing between the two spray pipes (the spray pipe consists of a straight pipe 13 and a nozzle 23) to adapt to concrete walls of different thicknesses.

[0039] The straight pipe 13 is connected by a threaded pipe 22, which facilitates disassembly or extension to adapt to different maintenance ranges. An end cap 24 can be installed on the bottom threaded pipe 22 to prevent leakage.

[0040] Then the motor 16 drives the worm gear 10 to rotate, which in turn drives the worm wheel 25 to rotate, thereby causing the support frame 17 to rotate and adjust the angle of the straight pipes 13 on both sides until the straight pipes 13 on both sides are in a horizontal state or tilted upward. Then the entire assembly is moved to a suitable position by the moving trolley 1, and then the rotating component is used to adjust the spraying direction so that the nozzles 23 cover both sides of the concrete wall.

[0041] Then, the mobile trolley 1 is pushed to move along the concrete wall, the water pump 2 delivers water to the distributor 3, and then enters the connecting pipes 21 on both sides through the hose 6, and finally sprays it evenly onto the concrete surface through the straight pipe 13 and the nozzle 23.

[0042] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
