Description

Technical Field

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

[0002] Traditional concrete curing methods often involve direct water spraying through pipes. This method requires continuous manual operation, is time-consuming and labor-intensive, and suffers from low water resource utilization and significant waste. While some existing concrete curing molds attempt to improve curing efficiency, they have obvious structural design flaws. For example, they are not easily adjustable according to the height of the concrete component and the curing location, and have poor adaptability to curing concrete of different sizes and locations, resulting in significant limitations. In addition, the fixing structure of some curing molds is poorly designed, making them prone to shaking and displacement during use, resulting in poor stability. This not only affects the curing effect but may also damage the concrete component due to mold displacement.

[0003] For example, patent document with patent application number 202221587325.0 discloses a concrete curing mold, which includes a fixed base plate, a fixing mechanism, a fixing seat, a top support rod, a PPR horizontal pipe, a PPR vertical pipe, and a mounting seat. The height can be adjusted by the cooperation of the top support rod and the threaded rod, water can be sprayed by the atomizing nozzle, and the PPR vertical pipe can be fixed by the fixing mechanism, which improves the shortcomings of traditional curing methods to a certain extent.

[0004] However, the above-mentioned literature has the following drawbacks: First, the PPR horizontal pipe and atomizing nozzle of the mold are installed in a fixed mounting base. Although the height can be adjusted by the top support rod, the distribution position of the atomizing nozzle is fixed and there is no lateral movement or angle adjustment structure. For large-area, irregularly shaped concrete components, it is difficult to achieve all-round, no-dead-angle curing. Some areas may be insufficiently cured because the nozzles cannot cover them, which affects the overall curing quality of the concrete.

[0005] Secondly, the water storage tank structure set in the mold only serves to protect the connecting rod, and the excess water generated during the curing process is directly lost, resulting in a waste of water resources.

[0006] Therefore, it is necessary to design a concrete curing mold that has all-round curing and adjustment functions, can realize water resource recycling, and has stronger stability. Utility Model Content

Limiting rings are fixedly installed on the top of the piston rod of each vertical cylinder. A maintenance spraying pipe is arranged between the two limiting rings. Both ends of the maintenance spraying pipe extend movably to the outside of the limiting ring on their corresponding side. Limiting nuts are screwed onto the external threaded sections of the maintenance spraying pipe at both ends of each limiting ring. A sealing cap is screwed onto one section of the maintenance spraying pipe. The other end of the maintenance spraying pipe is used to connect to an external water source through a water supply pipeline with a pump. Several atomizing nozzles are spaced apart along the length of the bottom of the maintenance spraying pipe above the maintenance chamber.

[0010] Based on any of the above technical solutions, a further optimization is made as follows: the inner cavity of each of the supporting risers is set as a reflux cavity, and the top of each reflux cavity is connected to the interior of the curing cavity through a reflux drop port set at the bottom of the curing cavity.

[0012] Based on any of the above technical solutions, the following further optimizations are made: each of the lifting cylinders is a lifting oil cylinder, each of the lifting oil cylinders lifts and lowers synchronously, the lifting stroke of the piston rod of each of the lifting oil cylinders is greater than the vertical depth of the curing chamber, and each of the lifting oil cylinders is controlled by an external hydraulic station.

[0025] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-5 As shown in the image.

[0026] Example 1: A concrete curing mold, characterized in that: it includes a curing box 1, a curing cavity 2 is provided inside the curing box 1, support risers 3 are installed at the four corners of the bottom of the curing box 1, the bottoms of two support risers 3 located on the same side are respectively fixed to the top of the connecting base 4, guide units are respectively fixed on both sides of each connecting base 4, a mobile spraying mechanism is installed on the top of the guide unit, the mobile spraying mechanism is driven by an external traction device to move back and forth along the front and rear direction of the curing box 1, the mobile spraying mechanism is connected to an external water source through a water supply pipeline with a pump, several synchronously lifting jacks are installed at the four corners of the bottom of the curing box 1, each jack cooperates to lift and adjust the concrete slab inside the curing cavity 2, and a return water pipe group 5 is provided below the curing box 1, which is connected to the inside of the four support risers 3, the return water pipe group 5 is connected to an external water source through an external return water pipeline with a pump.

[0027] The concrete curing mold accommodates concrete slabs in the curing chamber 2 inside the curing box 1. The curing box 1 is stably supported by the support riser 3 and fixed to the ground by the ground base 4. The guide unit provides movement guidance for the mobile spraying mechanism. The external traction equipment drives the mobile spraying mechanism to move back and forth along the curing box 1. At the same time, the water supply pipeline with pump delivers external water to the mobile spraying mechanism to realize dynamic spraying curing of the concrete slabs in the curing chamber 2. The synchronous lifting jack below the curing box 1 can work together to lift the concrete slabs in the curing chamber 2 to complete the repositioning. The support riser 3 is connected to the return water pipe group 5. In conjunction with the return water pipeline with pump, the excess water generated during the curing process is returned to the external water source to form a water circulation system.

[0028] This utility model adopts a support structure combining a support riser 3 and a ground base 4, which not only ensures the installation stability of the curing box 1 but also provides a channel for water return. The mobile spraying mechanism, in conjunction with the guide unit, enables comprehensive spraying of the concrete slab, avoiding curing dead spots. The synchronous lifting device design ensures a smooth lifting process for the concrete slab and prevents damage caused by uneven stress. The return water pipe group 5 is connected to the support riser 3 to form a water circulation system, which improves the utilization rate of water resources and meets the requirements of energy conservation and environmental protection.

[0029] Additionally, it should be noted that: curing box 1 and curing chamber 2 serve as the curing space for concrete slabs; the supporting riser 3 has the dual function of supporting curing box 1 and guiding the return water; the guiding unit provides guidance constraints for the movement of the mobile spraying mechanism, ensuring its stable movement trajectory; the mobile spraying mechanism can move and spray water under external drive to achieve uniform curing of concrete slabs; the jack can lift the cured concrete slabs to facilitate subsequent hoisting operations; and the return water pipe group 5 is responsible for collecting and transporting the return water, realizing the recycling of water resources.

[0030] During operation, water is supplied from an external water source, and each atomizing nozzle 6 sprays and cures the concrete slabs inside the curing chamber 2 below. During the curing process, the operation of the external traction equipment can drive the corresponding traction rod 7 to move the mobile spraying mechanism back and forth along the front and back direction of the curing chamber 2, ensuring the comprehensiveness of the concrete slab spraying and curing. Excess water sprayed inside the curing chamber 2 flows downward through the periphery of the curing chamber 2 and returns to the water source through the support riser 3 and the return water pipe group 5 for reuse.

[0031] In operation, an external water source supplies water to the mobile spraying mechanism through a water supply pipeline. The water is atomized by the atomizing nozzle 6 and sprayed onto the surface of the concrete slab inside the curing chamber 2 for curing. During the curing process, the external traction equipment drives the mobile spraying mechanism to reciprocate along the guide unit in the front and back direction of the curing chamber 2 through the traction rod 7, so that the atomizing nozzle 6 can cover the entire surface of the concrete slab. Excess water that is not absorbed after spraying flows downward along the periphery of the curing chamber 2 under the action of gravity, and flows back to the external water source through the support riser 3 and the return water pipe group 5 in sequence, completing the recycling of water.

[0032] This invention employs an atomizing nozzle 6 for spraying, causing the water to cover the concrete slab in a mist form. This ensures the humidity required for curing while avoiding the adverse effects of excessive water accumulation on the concrete slab. The reciprocating movement design of the mobile spraying mechanism ensures that all areas of the concrete slab receive uniform curing, improving the quality of curing. The water return path design enables the recycling of water resources, reducing curing costs and wastewater discharge.

[0033] Additionally, it should be noted that: the atomizing nozzle 6 sprays water after atomizing it, and its main function is to provide uniform moisture to the concrete slabs to meet their humidity requirements during the curing process; the external traction equipment drives the mobile spraying mechanism to move back and forth through the traction rod 7, and its function is to expand the spraying range and ensure the comprehensive curing of the concrete slabs; the flow guiding structure around the curing chamber 2 guides excess water to the support riser 3, and the support riser 3 and the return water pipe group 5 jointly undertake the function of transporting excess water back to the water source end to realize water circulation.

[0034] Once the curing is complete, the concrete slabs can be lifted upwards by the four lifting devices, making it easier to hoist them using hoisting equipment.

[0035] After the concrete slab has been cured, the four lifting devices are activated. Each lifting device extends upward synchronously, and its top contacts the bottom of the concrete slab and applies an upward force, lifting the concrete slab from the inside of the curing chamber 2. This causes the concrete slab to detach from the bottom of the curing chamber 2 and be suspended in the air. At this time, the hoisting equipment can be easily connected to the concrete slab and lifted away from the curing mold.

[0036] The design of the four lifting devices in this utility model ensures that the concrete slab is subjected to uniform force during the lifting process, avoiding deformation or damage to the concrete slab due to uneven force. The lifting operation separates the concrete slab from the curing chamber 2, providing operating space for the hoisting equipment, simplifying the hoisting process and improving work efficiency. The lifting devices are located below the curing box 1, which does not occupy the internal space of the curing chamber 2 and does not affect normal curing operations.

[0037] Additionally, it should be noted that the main function of the jack is to lift the concrete slab from the curing chamber 2 after curing is completed, so that it is freed from the constraints of the curing chamber 2; by lifting, the concrete slab is placed in a position that is easy to hoist, assisting the hoisting equipment in transferring the concrete slab, and realizing a smooth connection between the curing process and the subsequent process.

[0038] Based on any of the above technical solutions, a further optimization is made as follows: the guiding unit includes a guide rail 8 fixed on the ground, a traction sliding seat 9 is slidably engaged on the guide rail 8, the top of the traction sliding seat 9 is fixedly connected to the corresponding bottom of the mobile spraying mechanism, and traction rods 7 for connecting to external traction equipment are fixed at both ends of the traction sliding seat 9.

[0039] The guide rail 8 in the guide unit is fixed to the ground, providing stable sliding support and guiding constraint for the traction sliding seat 9; the traction sliding seat 9 is slidably engaged on the guide rail 8 and can move along the extension direction of the guide rail 8; since the top of the traction sliding seat 9 is fixedly connected to the bottom of the mobile spraying mechanism, the movement of the traction sliding seat 9 can drive the mobile spraying mechanism to move synchronously; the traction rods 7 at both ends of the traction sliding seat 9 are connected to the external traction equipment, and the external traction equipment drives the traction sliding seat 9 to slide along the guide rail 8 by pulling or pushing the traction rods 7, thereby realizing the movement of the mobile spraying mechanism.

[0040] The sliding engagement structure between the guide rail 8 and the traction sliding seat 9 ensures the smoothness and accuracy of the movement of the traction sliding seat 9, making the movement trajectory of the mobile spraying mechanism controllable. The traction sliding seat 9 is equipped with traction rods 7 at both ends, which facilitates external traction equipment to drive it from two directions, realizing the reciprocating movement of the mobile spraying mechanism. The guide rail 8 is fixed on the ground, which improves the stability of the entire guide unit and ensures that the guiding accuracy is not affected by external factors.

[0041] Additionally, it should be noted that: the main function of the guide rail 8 is to provide movement guidance and support for the traction sliding seat 9, and to limit its movement direction; the function of the traction sliding seat 9 is to connect the guide rail 8 with the mobile spraying mechanism, and to transmit its own movement to the mobile spraying mechanism; the function of the traction rod 7 is to act as a force transmission component, to transmit the driving force of the external traction equipment to the traction sliding seat 9, and to drive its movement.

[0042] Based on any of the above technical solutions, a further optimization is made as follows: the mobile spraying mechanism includes two vertical cylinders 10 respectively vertically mounted on the top of the corresponding traction sliding seat 9. Limiting rings 12 are fixedly installed on the top of the piston rod of each vertical cylinder 10. A maintenance spraying pipe 13 is arranged between the two limiting rings 12. Both ends of the maintenance spraying pipe 13 extend movably to the outside of the corresponding limiting ring 12. Limiting nuts 14 are screwed into the external threaded sections of the maintenance spraying pipe 13 at both ends of each limiting ring 12. A sealing cap 15 is screwed into one section of the maintenance spraying pipe 13. The other end of the maintenance spraying pipe 13 is used to connect to an external water source through a water supply pipeline with a pump. Several atomizing nozzles 6 are spaced apart along the length of the bottom of the maintenance spraying pipe 13 above the maintenance chamber 2.

[0043] In the mobile spraying mechanism, two vertical cylinders 10 are vertically mounted on top of the traction sliding seat 9. Their piston rods can extend and retract vertically, thereby driving the top limiting ring 12 to move up and down. The maintenance spray pipe 13 is positioned between the two limiting rings 12, with both ends extending out of the limiting rings 12. The maintenance spray pipe 13 can be fixed to the limiting rings 12 by the limiting nuts 14 screwed onto the limiting rings 12. At the same time, the horizontal position of the maintenance spray pipe 13 can be adjusted by adjusting the position of the limiting nuts 14. One end of the spray pipe 13 is connected to an external water source via a water supply pipeline with a pump, and the other end is sealed by a cap 15, allowing water to flow inside the curing spray pipe 13. Several atomizing nozzles 6 at the bottom of the curing spray pipe 13 are spaced apart along its length, which can atomize the water in the pipe and spray it onto the concrete slab in the curing chamber 2 below. The height of the curing spray pipe 13 and the atomizing nozzles 6 can be adjusted by extending and retracting the piston rod of the vertical cylinder 10 to meet the curing needs of concrete slabs of different thicknesses.

[0044] The vertical cylinder 10 of this utility model allows for adjustable height of the curing spray pipe 13, increasing the mold's adaptability to concrete slabs of different specifications. The limiting ring 12 and the limiting nut 14 work together to fix the curing spray pipe 13 and facilitate adjustment of its horizontal position, ensuring accurate relative positioning between the atomizing nozzle 6 and the concrete slab. The sealing caps 15 at both ends of the curing spray pipe 13 and the water supply pipeline connection design ensure normal flow of water in the pipe and normal operation of the atomizing nozzle 6. Multiple atomizing nozzles 6 are spaced apart along the length of the curing spray pipe 13, and combined with the reciprocating movement of the mobile spraying mechanism, comprehensive and uniform spraying of the concrete slab can be achieved.

[0045] Additionally, it should be noted that: the vertical cylinder 10 functions by moving the curing spray pipe 13 up and down through the extension and retraction of the piston rod, thereby adjusting the spraying height; the limiting ring 12 and the limiting nut 14 function to fix the curing spray pipe 13 and adjust its horizontal position; the curing spray pipe 13 functions to deliver water to each atomizing nozzle 6; the atomizing nozzle 6 functions to atomize the water and spray it onto the surface of the concrete slab; and the sealing cap 15 functions to seal one end of the curing spray pipe 13, ensuring that the water inside the pipe can be sprayed out from the atomizing nozzle 6.

[0046] Based on any of the above technical solutions, a further optimization is made as follows: the inner cavity of each of the supporting risers 3 is set as a return cavity 16, and the top of each of the return cavities 16 is connected to the interior of the curing cavity 2 through the return drop port 17 set at the bottom of the curing cavity 2.

[0047] The inner cavity of the support riser 3 is designed as a return cavity 16, serving as a channel for water return. The return outlet 17 at the bottom of the curing cavity 2 connects the inside of the curing cavity 2 with the top of the return cavity 16, allowing excess water generated after spraying inside the curing cavity 2 to flow into the return cavity 16 of the support riser 3 under gravity through the return outlet 17, and then return to the external water source through the return water pipe group 5, completing the water recycling cycle.

[0048] This invention sets the inner cavity of the support riser 3 as a return cavity 16, so that the support riser 3 has both support and return functions, eliminating the need for additional return pipes and saving mold space and manufacturing costs; the return drop port 17 directly connects the curing chamber 2 with the return cavity 16, shortening the water return path and improving return efficiency; each support riser 3 is equipped with a return cavity 16, which can collect water from multiple locations at the same time, speeding up the water discharge and preventing water accumulation in the curing chamber 2.

[0049] Additionally, it should be noted that the main function of the reflux chamber 16 is to serve as a channel for water reflux, accommodating and transporting excess water flowing in from the curing chamber 2; the function of the reflux outlet 17 is to connect the curing chamber 2 and the reflux chamber 16, providing a channel for water to flow from the curing chamber 2 to the reflux chamber 16, ensuring that the water can smoothly enter the reflux chamber 16.

[0050] Based on any of the above technical solutions, a further optimization is made as follows: the lifting device includes a lifting cylinder 19 fixedly installed at the connecting pipe 18 at the bottom of the curing box 1, and the top of the piston rod of each lifting cylinder 19 is movable and sealed and inserted into the lifting through hole 20 at the bottom of the curing chamber 2 and flush with the bottom of the curing chamber 2.

[0051] The lifting cylinder 19 in the lifting device is fixedly installed at the connecting pipe 18 at the bottom of the curing chamber 1, providing a stable installation base for the lifting operation. The piston rod of the lifting cylinder 19 is movable and sealed in the lifting through hole 20 at the bottom of the curing chamber 2. When not in operation, the top of the piston rod is flush with the bottom of the curing chamber 2, which does not affect the placement of the concrete slab in the curing chamber 2. When it is necessary to lift the concrete slab, the lifting cylinder 19 drives the piston rod to extend upward, and the top of the piston rod passes through the lifting through hole 20 and contacts the bottom of the concrete slab, thereby lifting the concrete slab upward. The sealing design can prevent water in the curing chamber 2 from flowing into the lifting cylinder 19 through the lifting through hole 20.

[0052] The lifting cylinder 19 of this utility model is fixed at the connecting pipe 18 at the bottom of the curing chamber 1. It has a compact structure and does not occupy the internal space of the curing chamber 2, thus ensuring the effective usable area of ​​the curing chamber 2. The top of the piston rod is flush with the bottom of the curing chamber 2, ensuring that the concrete slab can be placed stably in the curing chamber 2, avoiding the impact of uneven surface on the curing quality of the concrete slab. The movable and sealed insert structure not only ensures the normal extension and retraction of the piston rod, but also prevents water leakage from damaging the lifting cylinder 19, thereby improving the service life of the lifting device.

[0053] Additionally, it should be noted that: the function of the lifting cylinder 19 is to provide driving force, thereby lifting and resetting the concrete slab through the extension and retraction of the piston rod; the function of the piston rod is to directly contact the concrete slab and transmit the lifting force to lift the concrete slab; the function of the lifting through hole 20 is to provide a channel for the extension and retraction of the piston rod; the function of the sealing structure is to prevent water in the curing chamber 2 from entering the lifting cylinder 19 through the lifting through hole 20, thus protecting the lifting cylinder 19 for normal operation.

[0054] Example 2: Compared with Example 1, this example also includes the following technical features: Based on any of the above technical solutions, the following further optimizations are made: each of the lifting cylinders 19 adopts a lifting oil cylinder, each of the lifting oil cylinders lifts and lowers synchronously, the lifting stroke of the piston rod of each of the lifting oil cylinders is greater than the vertical depth of the curing chamber 2, and each of the lifting oil cylinders is controlled by an external hydraulic station.

[0055] The lifting device uses lifting cylinders as power components. An external hydraulic station provides hydraulic power to each lifting cylinder and controls its movement. Each lifting cylinder maintains synchronization during the lifting process to ensure that the concrete slab is subjected to uniform force and rises smoothly. The lifting stroke of the piston rod of the lifting cylinder is greater than the vertical depth of the curing chamber 2, ensuring that the piston rod can completely push the concrete slab out of the curing chamber 2. Through the control of the external hydraulic station, the synchronous extension and retraction of the piston rods of each lifting cylinder can be realized to complete the lifting and resetting operation of the concrete slab.

[0056] This invention uses lifting cylinders as the lifting power source, which has a large output force and stable operation, making it suitable for lifting heavy objects such as concrete slabs. The lifting cylinders move up and down synchronously, avoiding deformation or damage to the concrete slabs due to uneven force. The piston rod lifting stroke is greater than the vertical depth of the curing chamber 2, ensuring that the concrete slabs can be completely pushed out of the curing chamber 2, facilitating the operation of the hoisting equipment. The external hydraulic station provides centralized control, making the actions of each lifting cylinder coordinated, with high control precision and convenient operation.

[0057] Additionally, it should be noted that: the function of the lifting cylinder is to convert hydraulic energy into mechanical energy, and to generate lifting force through the extension and retraction of the piston rod to achieve the lifting and lowering of the concrete slab; the function of the external hydraulic station is to provide hydraulic power to the lifting cylinder and to achieve synchronous action control of the lifting cylinder by controlling the flow and direction of the hydraulic oil; the lifting stroke design of the piston rod ensures that the concrete slab can be completely pushed out of the curing chamber 2 to meet the hoisting requirements.

[0058] Based on any of the above technical solutions, a further optimization is made: both vertical cylinders 10 are vertical hydraulic cylinders, and both vertical hydraulic cylinders are controlled by an external hydraulic station to achieve synchronous lifting.

[0059] The two vertical cylinders 10 in the mobile spraying mechanism are vertical hydraulic cylinders, which are powered and controlled by an external hydraulic station. The external hydraulic station drives the piston rods of the two vertical hydraulic cylinders to extend and retract synchronously by controlling the input and output of hydraulic oil. Since the top of the piston rod of the vertical hydraulic cylinder is connected to the limiting ring 12, the synchronous extension and retraction of the piston rod drives the limiting ring 12 and the curing spray pipe 13 to move up and down synchronously, thereby realizing the synchronous adjustment of the height of the curing spray pipe 13 and the atomizing nozzle 6 to adapt to the curing needs of concrete slabs of different heights.

[0060] This utility model uses a vertical cylinder as the vertical cylinder 10, which has the characteristics of stable output force and high control precision, and can accurately control the height of the maintenance spray pipe 13. The two vertical cylinders are controlled by the same external hydraulic station and realize synchronous lifting and lowering, ensuring that the maintenance spray pipe 13 always remains horizontal during the lifting and lowering process, avoiding uneven spraying of the atomizing nozzle 6 due to inconsistent height at both ends. The use of external hydraulic station control facilitates integration with the control of the lifting cylinder, realizing centralized control of the entire mold and improving the convenience of operation.

[0061] Additionally, it should be noted that the vertical hydraulic cylinder converts hydraulic energy into mechanical energy, and drives the maintenance spray pipe 13 to move up and down through the extension and retraction of the piston rod, thereby adjusting the spraying height; the external hydraulic station provides hydraulic power to the vertical hydraulic cylinder and controls its piston rod to extend and retract synchronously, ensuring that the maintenance spray pipe 13 moves horizontally.

[0062] Based on any of the above technical solutions, a further optimization is made as follows: a screen plate 11 is detachably and fixedly installed on the upper part of each of the reflux chambers 16, and a plurality of screen holes are provided on the surface of each of the screen plates 11.

[0063] A screen plate 11 is detachably installed on the upper part of the return chamber 16 of each support riser 3. The screen mesh holes on the surface of the screen plate 11 allow water to pass through while blocking impurities (such as concrete debris, dust, etc.) generated during the curing process from entering the return chamber 16. When water flows from the curing chamber 2 to the return chamber 16 through the return outlet 17, it first passes through the screen plate 11 for filtration. Impurities are trapped on the screen plate 11. The filtered water enters the return chamber 16 through the screen mesh holes and then flows back to the external water source through the return water pipe group 5. Since the screen plate 11 is detachable, it can be removed for cleaning or replacement when impurities accumulate to a certain extent.

[0064] The screen plate 11 of this utility model can effectively filter impurities in the return water, prevent impurities from entering the return chamber 16 and the return water pipe group 5 and causing blockage, and ensure the smooth flow of the water circulation system. The screen plate 11 adopts a detachable fixed installation, which is convenient for regular cleaning and replacement, and the maintenance operation is simple. The design of the screen mesh can be selected according to the size of common impurities, improving the filtration effect while ensuring the normal flow rate of the water.

[0065] In addition, it should be noted that the main function of the filter screen plate 11 is to filter impurities in the return water and purify the return water quality; the function of the filter screen holes is to allow water to pass through while blocking impurities; the detachable installation method is to facilitate the cleaning and replacement of the filter screen plate 11 and ensure the continuous effectiveness of the filtration function.
