Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and particularly to an energy-saving concrete precast curing device. Background Art

[0002] In the process of producing concrete precast components, the reason why concrete can gradually set and harden after pouring and molding is that the core mechanism lies in the hydration of cement. This chemical reaction process has quite strict requirements for temperature and humidity. Only under appropriate temperature and humidity conditions can cement be fully hydrated, thereby ensuring that the concrete has qualified mechanical properties and mechanical performance after hardening. Therefore, in order to create an environment conducive to the hardening of concrete, the curing link is particularly important.

[0003] At present, after the production of concrete precast components is completed, they are usually neatly placed in the factory area. In order to maximize the use of space and reduce the floor area, these precast components are often stored in a stacked manner. Between adjacent precast components, bricks are usually used to separate them to ensure a certain ventilation and humid space. However, in terms of curing, the traditional manual watering method is still generally used. In actual operation, workers need to hold a water pipe and water each precast component one by one, and continuously move the water pipe nozzle to ensure that the water flow can accurately spray into the gap between adjacent precast components, so as to achieve a comprehensive curing effect.

[0004] However, it should be noted that since the precast components are usually stacked and placed, and most of them are relatively large in volume, during the curing process, the adjacent surfaces between the concrete precast components are often difficult to be fully wetted. This not only affects the uniformity and comprehensiveness of curing, but also may cause problems such as uneven performance and cracking during the hardening process of the precast components, thereby reducing their overall quality and service life. For this reason, we propose an energy-saving concrete precast curing device. Summary of the Invention

[0005] To solve the above technical problems, the embodiment of the present application provides an energy-saving concrete precast curing device, including a plurality of support units, and the support units are located between two adjacent precast components to support the precast components at intervals:

Furthermore, the water pump can transport water to the spray head to spray water for curing the gap between adjacent precast components;

[0007] It further includes a driving member, which is movably arranged in the support column. When water flows into the support column, the water flow can drive the driving member to rotate.

Specific embodiments

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: Please refer to Figures 1 - 9 , the present invention provides a technical solution: an energy-saving concrete precast component curing device, including a plurality of support units 1. The support units 1 are located between two adjacent precast components to support the precast components at intervals, so that the precast components are stacked. In actual use, a plurality of support units 1 are combined to form a complete support system and placed on the upper surface of one of the precast components, and then the next precast component is placed on the top of the support unit 1, and so on to realize the stacking of a plurality of precast components:

[0035] The support unit 1 includes a support column 2, and a water pipe 3 is wound around the middle of the support column 2. Any one of the support columns 2 is connected to a water pump through the water pipe 3, and the other support columns 2 are connected through the water pipe 3. In addition, a spray head 4 is arranged on the outer side of the upper part of the support column 2. Therefore, the water pump can deliver water to the spray head 4 for spraying. And because the support column 2 is located between the precast components, it can spray and cure the gaps between adjacent precast components;

[0036] Each support column 2 is an independent entity, and different support columns 2 are connected by water pipes 3. Therefore, in actual use, the position and number of support columns 2 can be allocated according to the shape of the prefabricated parts, so that they can stably support the prefabricated parts. At the same time, after water is passed, the upper and lower prefabricated parts can be sprayed with water for coverage.

[0037] The apparatus further comprises a driving member 5, which is movably arranged in the support column 2. When water flows into the support column 2, the water flow can drive the driving member 5 to rotate. An adjusting member 6 is movably arranged in the support column 2. The adjusting member 6 is transmission-connected with the driving member 5 and can drive the spray head 4 to move to increase the water spray range. By movably setting the spray head 4, its water spray coverage range is increased, and the use of the support column 2 can be reduced to reduce the cost.

[0038] The supporting structure further comprises a rotating assembly 7 , which is arranged at the lower half of the supporting column 2 and is in transmission connection with the driving member 5 .

[0039] A groove is provided in the middle of the support column 2, and a flow channel is provided inside the support column 2. One end of the water pipe 3 is connected to the flow channel and a connecting ring 8 is rotatably provided at the end. A connecting port 9 is provided on the outer side of the groove of the support column 2. An inner thread is provided on the inner wall of the connecting port 9, and an outer thread is provided on the outer side of the connecting ring 8. When in use, the connecting ring 8 is screwed into the connecting port 9 to realize the connection between the water pipe 3 and the support column 2. Multiple support columns 2 are connected in this way, thereby realizing a complete support water spraying maintenance system.

[0040] The driving member 5 includes a mounting frame 51 arranged in the connecting port 9, a driving shaft 52 is rotatably arranged on the mounting frame 51, a driving blade 53 is arranged on the outer side of the driving shaft 52, and a driving bevel gear 54 is arranged at the end of the driving shaft 52. Since the number of prefabricated parts placed in the factory is large enough, multiple groups of support units 1 need to be arranged, which requires considerable water pressure to transport the water flow. Therefore, when the water flow is transported, the flow of the water flow can drive the driving blade 53 to rotate, thereby driving the driving shaft 52 and the driving bevel gear 54 to rotate.

[0041] A plurality of through holes are provided in the support column 2, which are connected to the flow channel, and a branch pipe 10 is provided in the through hole, and a hose 11 is connected to the outer end of the branch pipe 10, and the nozzle 4 is connected to the hose 11. A flexible bracket 12 for mounting the nozzle 4 is fixedly provided on the outer side of the support column 2. Both the flexible bracket 12 and the hose 11 are made of rubber to increase the service life. The nozzle of the nozzle 4 is inclined upward and faces the bottom surface of the upper prefabricated part;

[0042] During actual spray water curing, due to the stacked arrangement of precast components, the water on the bottom surface of the upper precast components will drip under the action of gravity after spraying, so it is difficult to remain on its surface and penetrate into the interior. On the contrary, the upper surface of the lower precast components is prone to retain water. Therefore, the nozzle 4 is designed to face the bottom surface of the upper precast components. In this way, when spraying water, the water flow first sprays onto the bottom surface of the upper precast components and then drips onto the upper surface of the lower precast components. There is no need to spray water on the upper surface of the lower precast components separately, saving water resources. At the same time, the spraying operation can be set to be in small amounts but multiple times, spraying water on the bottom surface of the upper precast components multiple times to promote the penetration of water into its bottom surface, and the excess water will naturally drip onto the upper surface of the lower precast components to cure it.

[0043] An annular groove 13 is formed in the inner wall of the support column 2. The branch pipe 10 is slidably arranged in the through hole and its end is located in the annular groove 13. The adjusting member 6 includes an adjusting shaft 61 rotatably arranged in the flow channel. An adjusting bevel gear 62 engaged with the driving bevel gear 54 is arranged at the bottom end of the adjusting shaft 61. A rotating ring 63 is arranged at the top end of the adjusting shaft 61. A plurality of arc plates 64 are arranged on the outer side of the rotating ring 63. A connecting plate 65 is arranged at the top of one end of the branch pipe 10 located in the annular groove 13. A connecting spring 66 is arranged on the connecting plate 65, and the end of the connecting spring 66 is connected to the side wall of the annular groove 13.

[0044] When the driving bevel gear 54 rotates, it can drive the adjusting bevel gear 62 to rotate, thereby driving the adjusting shaft 61 and the rotating ring 63 to rotate. The rotating ring 63 drives the arc plates 64 to rotate, and the plurality of arc plates 64 sequentially press against the branch pipe 10 to drive the nozzle 4 to move, so that the nozzle 4 swings during spraying, increasing its coverage range.

[0045] The rotating assembly 7 includes a rotating ring 71 rotatably arranged on the outer side of the bottom of the support column 2. A transmission shaft 72 is rotatably arranged inside the support column 2. A transmission bevel gear 73 engaged with the driving bevel gear 54 is arranged at one end of the transmission shaft 72, and a transmission gear ring 74 is arranged at the other end. A transmission gear 75 engaged with the transmission gear ring 74 is rotatably arranged inside the support column 2. Tooth grooves are formed on the inner side of the rotating ring 71, and the transmission gear 75 cooperates with the tooth grooves to drive the rotating ring 71 to rotate during rotation. A plurality of receiving frames 76 are arranged on the outer side of the rotating ring 71, and water passing holes 77 are formed at the ends of the receiving frames 76.

[0046] When the driving bevel gear 54 rotates, it can drive the transmission bevel gear 73 and the transmission shaft 72 to rotate, thereby driving the transmission gear ring 74 and the transmission gear 75 to rotate. The transmission gear 75 drives the rotating ring 71 to rotate, and finally drives a plurality of receiving frames 76 to rotate. The receiving frames 76 can catch the water dripping from above, and then drive the water to be thrown out through the water passing holes 77 by centrifugal force during their rotation. At the same time, there are also gaps between the plurality of receiving frames 76, so the water can be evenly distributed on the upper surface of the lower precast components.

[0047] A plurality of receiving frames 76 are arranged in a circle outside the rotating ring 71. The cross-section of the receiving frame 76 gradually decreases from its fixed end to its free end. Since the nozzle 4 is arranged outside the support column 2, when the nozzle of the nozzle 4 faces a position closer to the support column 2, the distance between the nozzle of the nozzle 4 and the prefabricated member is also relatively close at this time. At this time, more water will bounce and fall. Therefore, the receiving frame 76 is set in a gradually changing shape, which helps it receive the water around the support column 2.

[0048] A spoiler 78 is fixedly arranged at the bottom of the receiving frame 76, which can effectively disturb the air between the two prefabricated members during rotation, promoting air flow.

[0049] Embodiment 2: Please refer to Figure 10 , which is different from Embodiment 1. In Embodiment 2, a single-piece fan blade 79 is fixedly arranged at the bottom of the receiving frame 76. When the rotating ring 71 drives the receiving frame 76 to rotate, it can drive the single-piece fan blade 79 to rotate. When the single-piece fan blades 79 at the bottoms of the plurality of receiving frames 76 rotate, they can produce an effect similar to that of a fan, which can blow the wind onto the upper surface of the lower prefabricated member and then diffuse outward along its upper surface, helping the water flow to diffuse outward. At the same time, it can drive the air flow in the gap between the two prefabricated members, contributing to uniform temperature distribution.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
