[0002] In the field of construction, concrete, as a key material, is widely used in various construction projects. With the continuous development of construction technology, precast concrete parts have gradually become an indispensable part of construction due to their convenient characteristics. Precast concrete parts refer to concrete components that are prefabricated and formed in factories or construction sites. Through mold forming and standardized production processes, they can effectively improve construction efficiency, ensure component quality, and reduce the impact of on-site construction on the environment. In the production process of precast concrete parts, spraying water for moisturizing maintenance after pouring is a crucial link. Spraying water for moisturizing maintenance can effectively prevent the evaporation of water on the concrete surface too quickly and avoid cracks caused by drying, thereby ensuring the strength and durability of precast concrete parts.

[0003] In the prior art, when precast concrete parts are sprayed with water for curing, since they are exposed to the outside and not in a relatively closed environment, the water sprayed on their surface tends to evaporate quickly, resulting in the need for multiple water spraying. In addition, this frequent spraying method is not only time-consuming and labor-intensive, but may also lead to uneven curing, affecting the strength and durability of the precast concrete parts.

[0020] The above technical solution of the present invention has the following beneficial technical effects:

[0021] 1. The present invention first places the precast concrete parts in the loading frame in sequence. In the initial state, the electromagnetic seat is energized to magnetically attract the upper shielding component. Then, the electromagnetic seat is driven by the driving member to move the first electromagnetic block along the length direction of the loading frame. When the electromagnetic seat moves, the water source is guided to the upper spraying member through the water supply member, and the water source is sprayed on the top of the precast concrete part through the upper spraying member. When the electromagnetic seat moves, the upper magnetic shielding film is pulled out from the upper shielding component. When the electromagnetic seat moves to the position of the first electromagnetic block, the first electromagnetic block is energized so that the end of the upper magnetic shielding film is magnetically connected to the first electromagnetic block, and then the electromagnetic seat is powered off. At this time, the upper magnetic shielding film covers the top of the precast concrete part, placing the precast concrete part in a relatively closed space, effectively reducing the rapid evaporation of water on the precast part, avoiding the uneven maintenance problem caused by frequent spraying of water, and thus improving the strength and durability of the precast concrete part.

[0022] 2. When spraying water on concrete prefabricated parts in the traditional way, only one side of the prefabricated parts can be sprayed with water at a time. When spraying water on the other side, it is necessary to turn it over, which is troublesome. When the driving part drives the electromagnetic seat to move along the loading frame, the upper spraying part sprays water on the top of the prefabricated part, and the water supply component can be used to guide the water to the lower spraying part located under the loading frame at the same time. The lower spraying part sprays water on the bottom of the prefabricated part, so as to realize the simultaneous spraying of water on the top and bottom surfaces of the prefabricated part, avoiding the troublesome operation of turning over the prefabricated part to spray water on the other side in the traditional method, greatly improving the spraying efficiency, saving time and manpower;

[0023] 3. When the driving member drives the electromagnetic seat to move to the position of the first electromagnetic block, so that the upper shielding assembly covers the top of the preform, the third electromagnetic block at the bottom of the lower spraying member immediately docks with the lower magnetic shielding film on the lower shielding assembly, and the third electromagnetic block can be energized, so that the lower magnetic shielding film is magnetically connected to the third electromagnetic block. Since the electromagnetic seat is in a power-off state at this time, the upper shielding assembly is magnetically connected to the first electromagnetic block, and the electromagnetic seat can be driven by the driving member to return to its original position along the loading frame. When the electromagnetic seat returns to its original position, the third electromagnetic block on the lower spraying member can be used to pull the lower magnetic shielding film from the lower shielding assembly and form a covering space at the bottom of the preform. Through the covering effect of the upper shielding assembly and the lower spraying member, it can act on the top and bottom of the preform at the same time, further preventing the rapid evaporation of moisture at the top and bottom of the preform, and ensuring the uniformity and effectiveness of the curing process.

[0024] 4. The present invention can quickly coat the top and bottom of the precast parts after spraying water on them, which can effectively reduce water evaporation and ensure that the precast parts always maintain appropriate humidity during the curing process, thereby achieving uniform and efficient moisturizing curing and further improving the strength and durability of the concrete precast parts.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0038] like Figure 1-11 As shown, a concrete maintenance device for construction proposed by the present invention comprises a loading frame 1, an electromagnetic seat 2 and a driving member 3;

[0039] The electromagnetic seat 2 is arranged on the loading frame 1, and the driving member 3 is used to drive the electromagnetic seat 2 to move along the length direction of the loading frame 1. The side of the electromagnetic seat 2 is provided with an upper spraying member 4 located above the loading frame 1, and the upper spraying member 4 is used to spray water on the top of the preform. The electromagnetic seat 2 is provided with a lower spraying member 6 located below the loading frame 1, and the lower spraying member 6 is used to spray water on the bottom of the preform.

[0040] An upper shielding assembly 5 is installed at one end of the loading frame 1, and the upper shielding assembly 5 includes an upper magnetic shielding film 51 magnetically connected to the second electromagnetic block 21, and a first electromagnetic block 101 corresponding to the upper magnetic shielding film 51 is installed on the top of the other end of the loading frame 1;

[0041] A third electromagnetic block 8 is installed at the bottom of the lower spraying member 6, and a lower shielding assembly 7 is installed at the bottom of the other end of the loading frame 1. The lower shielding assembly 7 includes a lower magnetic shielding film member 71 corresponding to the third electromagnetic block 8;

[0042] A water supply assembly 9 is mounted on the electromagnetic base 2 for supplying water to the upper spraying member 4 and the lower spraying member 6 respectively;

[0043] The loading frame 1 serves as the supporting structure of the entire device, carrying the electromagnetic seat 2, the driving member 3 and placing the preformed parts. The electromagnetic seat 2 can be moved on the loading frame 1 by the driving member 3, so as to realize the spraying and coating operations on different positions of the preformed parts. The upper spraying member 4 and the lower spraying member 6 are respectively located above and below the electromagnetic seat 2. During the movement of the electromagnetic seat 2, the water supply component 9 provides it with a water source to realize water spraying on the top and bottom of the preformed parts. The upper shielding component 5 and the lower shielding component 7 cooperate with the electromagnetic seat 2 and the third electromagnetic block 8 through electromagnetic connection, and are unfolded to form a coating at the right time to reduce water evaporation. This design enables the device to perform comprehensive moisturizing maintenance on the preformed parts and improve the maintenance effect and efficiency.

[0044] like Figure 1 , Figure 8 and Fig. 9 As shown, in this embodiment, the upper shielding assembly 5 also includes a first roller 52 and a first coil spring 53. Two symmetrically arranged assembly blocks 103 are installed at one end of the loading frame 1. The first roller 52 is rotatably connected between the two assembly blocks 103. The upper magnetic shielding film 51 is wound relative to the first roller 52. The first coil spring 53 is matched between the upper magnetic shielding film 51 and the first roller 52, and the first coil spring 53 is used to restore the pulled upper magnetic shielding film 51 to its original position; the first roller 52 can rotate freely under the support of the assembly block 103. The upper magnetic shielding film 51 is wound on the first roller 52. When the electromagnetic seat 2 moves, the upper magnetic shielding film 51 will be pulled out due to the electromagnetic effect. At this time, the first coil spring 53 is stretched to store elastic potential energy. When the maintenance operation is completed, the electromagnetic seat 2 returns or no longer produces tension on it, the first coil spring 53 releases the elastic potential energy, driving the first roller 52 to reverse, so that the upper magnetic shielding film 51 is rewound back on the first roller 52, which is convenient for next use, thereby ensuring the automatic resetting function of the upper shielding component 5 and improving the convenience and operability of the device.

[0045] like Figure 8 and Fig. 9As shown, in this embodiment, the upper magnetic shielding film member 51 includes a first shielding film 511 and a first magnetic block 512. The first shielding film 511 is wound relative to the first roller 52. The first coil spring 53 is fitted between the first roller 52 and the first shielding film 511. The first magnetic block 512 is connected to one end of the first shielding film 511. An opening is provided at the bottom of the electromagnetic seat 2, and a second electromagnetic block 21 is installed in the opening. The first magnetic block 512 is magnetically connected to the bottom of the second electromagnetic block 21, and one end of the first magnetic block 512 away from the first shielding film 511 extends out of the opening and is located below the upper spraying member 4. In the initial state, the electromagnetic seat 2 is energized so that the second electromagnetic Block 21 generates magnetism to attract the first magnetic block 512 of the upper magnetic shielding film 51, so that it remains near the bottom of the electromagnetic base 2. When the electromagnetic base 2 moves, it drives the first magnetic block 512 to move, thereby pulling the first shielding film 511 out from the first roller 52. When the electromagnetic base 2 moves to the first electromagnetic block 101 at the other end of the loading frame 1, the first electromagnetic block 101 is energized to attract the first magnetic block 512, so that the first shielding film 511 covers the top of the prefabricated part, forming a relatively closed space to reduce moisture evaporation. This electromagnetic connection and mobile coordination method ensures the effective deployment and fixation of the upper shielding film and improves the moisturizing effect of the concrete prefabricated parts.

[0046] like Figure 1 , Fig.10 As shown, in this embodiment, the lower shielding assembly 7 also includes an assembly box 72, a second roller 73 and a second coil spring 74. The assembly box 72 is installed at the bottom of the other end of the loading frame 1, and the second roller 73 is installed in the assembly box 72 for transverse rotation. The lower magnetic shielding film 71 is wound relative to the second roller 73. An opening 75 is opened on the side of the assembly box 72 close to the third electromagnetic block 8, and one end of the lower magnetic shielding film 71 extends out of the opening 75. A second coil spring 74 is provided between the lower magnetic shielding film 71 and the second roller 73; the assembly box 72 is the second roller 73 and the lower magnetic shielding film The membrane 71 provides installation and protection space, the second roller 73 can rotate in the assembly box 72, and the lower magnetic shielding membrane 71 is wound on it. When the electromagnetic base 2 moves to the corresponding position, the connection between the third electromagnetic block 8 and the lower magnetic shielding membrane 71 causes the lower magnetic shielding membrane 71 to be pulled out from the opening 75, and the second coil spring 74 is stretched. After the maintenance is completed, the electromagnetic base 2 returns or the third electromagnetic block 8 is powered off, and the second coil spring 74 contracts to drive the second roller 73 to reverse, so that the lower magnetic shielding membrane 71 is reset, ensuring the automatic recovery function of the lower shielding component 7 and maintaining the good operation state of the device.

[0047] like Fig.10 and Fig.11As shown, in this embodiment, the lower magnetic shielding film 71 includes a second shielding film 711, which is wound relative to the second roller 73, and the second coil spring 74 is engaged between the second shielding film 711 and the second roller 73, and the second coil spring 74 is used to restore the second shielding film 711 after it is pulled out, one end of the second shielding film 711 extends out of the opening 75 and is connected to the second magnetic block 712, and the second magnetic block 712 corresponds to the third electromagnetic block 8; initially, the lower magnetic shielding film 71 is wound on the second roller 73, when the electromagnetic seat 2 moves to make the third electromagnetic block 8 close to the lower shielding component 7, the third electromagnetic block 8 is magnetically connected to the second magnetic block 712, pulling the second shielding film 711 out of the opening 75 and covering the bottom of the preform, the second coil spring 74 plays a role of balance and reset in this process, ensuring the stable expansion and retraction of the lower shielding film, and working together with the upper shielding component 5 to effectively prevent the evaporation of moisture at the bottom of the preform and improve the maintenance effect.

[0048] like Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, the upper spraying member 4 includes an upper spraying pipe 41, a first nozzle 42 and two fixed blocks 43. The two fixed blocks 43 are symmetrically installed on the side of the electromagnetic base 2. The upper spraying pipe 41 is connected between the two fixed blocks 43. The upper spraying pipe 41 is connected with a plurality of first nozzles 42 arranged at intervals and tilted downward. The upper spraying pipe 41 is connected with the water supply component 9; the fixed block 43 firmly installs the upper spraying pipe 41 on the side of the electromagnetic base 2. After the water provided by the water supply component 9 enters the upper spraying pipe 41, it is evenly sprayed on the top of the prefabricated part through the downward-tilted first nozzle 42. The inclined design of the first nozzle 42 ensures that the water can cover a larger area of ​​the top of the prefabricated part, making the water spraying more uniform, improving the moisturizing effect on the top of the prefabricated part, and facilitating the maintenance of the concrete. In addition, the inclined first nozzle 42 can effectively blow away impurities attached to the surface of the concrete prefabricated part.

[0049] like Figure 1 and Figure 6As shown, in this embodiment, the lower spraying member 6 includes two mounting frames 61, a second spraying pipe 62 and a second nozzle 63. The two mounting frames 61 are respectively mounted at both ends of the electromagnetic base 2. The second spraying pipe 62 is connected between the two mounting frames 61 and is located below the loading frame 1. The second spraying pipe 62 is connected with a plurality of second nozzles 63 arranged at intervals and tilted upward. The water supply assembly 9 is connected to the second spraying pipe 62. The third electromagnetic block 8 is mounted below the two mounting frames 61 and corresponds to the second magnetic block 712. The mounting frame 61 supports the second spraying pipe 62 at a suitable position below the electromagnetic base 2. After the water transported by the water supply assembly 9 enters the second spraying pipe 62, it is sprayed to the bottom of the prefabricated part through the second nozzle 63 tilted upward. The arrangement and tilt angle of the nozzle ensure effective water spraying on the bottom of the prefabricated part. At the same time, water can be continuously sprayed during the movement of the electromagnetic base 2. The cooperation of the third electromagnetic block 8 and the lower shielding assembly 7 realizes the coating operation while spraying water, thereby improving the maintenance efficiency and effect.

[0050] like Figure 1 , Figure 6 ,and Figure 7 As shown, in this embodiment, the water supply assembly 9 includes a water tank 91, which is installed on the top of the electromagnetic base 2, and a water pump 92 is installed at the bottom of the water tank 91. The liquid outlet of the water pump 92 is connected to a water supply pipe 93, one end of the water supply pipe 93 is connected to a diverter ball 94, and the diverter ball 94 is connected to a first water pipe 95 and a second water pipe 96, one end of the first water pipe 95 is connected to the upper spray pipe 41, and one end of the second water pipe 96 is connected to the second spray pipe 62; the water tank 9 The water source required for storage and maintenance is pumped out by the water pump 92 when working, and is delivered to the diverter ball 94 through the water supply pipe 93. The diverter ball 94 evenly distributes the water to the first water pipe 95 and the second water pipe 96, and then supplies the water to the upper spray pipe 41 and the second spray pipe 62 respectively, so as to realize the simultaneous water supply to the top and the bottom of the precast part. This structure ensures the stability and uniformity of the water supply, and provides a reliable water source support for the moisture maintenance of the concrete precast parts.

[0051] like Figure 1As shown, in this embodiment, the driving member 3 includes a motor 31, a screw 32 and a guide rod 33. Two symmetrically arranged slide grooves 104 are provided on the electromagnetic base 2. The screw 32 and the guide rod 33 are arranged in the two slide grooves 104 respectively. The motor 31 is installed at the other end of the loading frame 1, and the output end of the motor 31 is connected to one end of the screw 32. Two symmetrically arranged sliders 22 are installed at the bottom of the electromagnetic base 2. The two sliders 22 are respectively sleeved on the screw 32 and the guide rod 33. One slider 22 is threadedly matched with the screw 32, and the other slider 2 2 and the guide rod 33 are slidably matched; after the motor 31 is started, it drives the screw 32 to rotate. Since the slider 22 at the bottom of the electromagnetic seat 2 is threadedly matched with the screw 32, the electromagnetic seat 2 will move along the axial direction of the screw 32 under the rotation of the screw 32. At the same time, the sliding match between the guide rod 33 and another slider 22 ensures the smooth movement of the electromagnetic seat 2. Driven by the driving member 3, the electromagnetic seat 2 can be accurately moved to the specified position on the loading frame 1, realizing the water spraying and film coating maintenance operations on different parts of the prefabricated parts, ensuring the orderly progress of the maintenance process.

[0052] like Figure 1 As shown, in this embodiment, two bearing plates 102 are installed in the loading frame 1, and the bearing plates 102 are used to place prefabricated parts. The bearing plates 102 provide a placement plane for the concrete prefabricated parts, so that the prefabricated parts can maintain a stable position in the loading frame 1, which is convenient for the upper spraying part 4 and the lower spraying part 6 to spray water on them for curing, and the upper shielding component 5 and the lower shielding component 7 to coat them for film, ensuring that the prefabricated parts will not be displaced during the entire curing process, thereby ensuring the consistency of the curing effect.

[0053] The specific working principle of the present invention is as follows:

[0054] First, the concrete prefabricated part is placed in the loading frame 1, so that the two ends of the prefabricated part are placed on the two bearing plates 102 respectively. After the device is started, the electromagnetic seat 2 is energized in the initial state, so that the first magnetic block 512 of the upper shielding component 5 is magnetically connected with the second electromagnetic block 21 at the bottom of the electromagnetic seat 2, and the motor 31 of the driving member 3 is started to drive the screw 32 to rotate, so that the electromagnetic seat 2 moves along the length direction of the loading frame 1. During the movement, the water pump 92 of the water supply component 9 pumps out the water in the water tank 91, and transports the water to the upper spray pipe 41 of the upper spray member 4 and the second spray pipe 62 of the lower spray member 6 through the water supply pipe 93, the diverter ball 94, the first water guide pipe 95 and the second water guide pipe 96 respectively. The upper spray pipe 41 sprays water to the top of the prefabricated part by the first nozzle 42 downwardly tilted, and the second spray pipe 62 sprays water to the bottom of the prefabricated part by the second nozzle 63 upwardly tilted, so as to realize the simultaneous spraying of the top and bottom surfaces of the prefabricated part;

[0055] When the electromagnetic seat 2 moves to the first electromagnetic block 101 at the other end of the loading frame 1, the first electromagnetic block 101 is energized to attract the first magnetic block 512 of the upper magnetic shielding film 51, so that the first shielding film 511 of the upper magnetic shielding film 51 covers the preform. At the same time, the third electromagnetic block 8 at the bottom of the lower spraying member 6 docks with the second magnetic block 712 of the lower magnetic shielding film 71 of the lower shielding assembly 7 and energizes. Then the second electromagnetic block 21 is de-energized, and the electromagnetic seat 2 is driven to return to its original position through the driving member 3. , so that the second shielding film 711 of the lower magnetic shielding film 71 covers the bottom of the prefabricated part, forming a relatively closed space, effectively reducing water evaporation. After the maintenance is completed, the first electromagnetic block 101 and the third electromagnetic block 8 can be powered off respectively, so that the first shielding film 511 and the second shielding film 711 can be restored to their original positions respectively, preparing for the next maintenance of the prefabricated part. The whole process realizes efficient and uniform moisturizing maintenance of the concrete prefabricated parts through the synergistic effect of various components, thereby improving the strength and durability of the prefabricated parts.
