Therefore, they should not be construed as limitations on this invention.

[0024] like Figures 1-3 As shown, an embodiment of the present invention provides a precast beam yard maintenance system, comprising: multiple scaffolds 1 spanning above a precast beam 2 and spaced apart along the length of the precast beam 2; two water tanks 3 respectively located below the multiple scaffolds 1 on both sides of the precast beam 2 and fixedly connected to their adjacent ends, each water tank 3 being driven to move by a first driving assembly; a spray frame 4 spanning above the precast beam 2 on the inner side of the multiple scaffolds 1, both ends of the spray frame 4 being slidably connected to the two water tanks 3 and driven to move along the length of the water tanks 3 by a second driving assembly; wherein the spray frame 4 is supplied with water by the water tanks 3; a return water inlet is provided on the side of the water tank 3 near the precast beam 2, and a receiving plate 5 is provided inside the return water inlet, one side of the receiving plate 5 being hinged to the return water inlet and driven to rotate by a third motor 6, and the other opposite side being configured to overlap with the side wall of a base 7.

[0025] In the above embodiment, the precast beam yard curing system includes multiple sheds 1, two water tanks 3, and a spray frame 4. The multiple sheds 1 span above the precast beam 2 and are spaced apart along the length of the precast beam 2. The two water tanks 3 are respectively located below the multiple sheds 1 on both sides of the precast beam 2 and are fixedly connected to the adjacent ends of the multiple sheds 1. The multiple sheds 1 and the two water tanks 3 are fixedly connected to form a whole, and their inner sides form a precast beam curing area. The two water tanks 3 are synchronously driven to move by a first drive assembly, thereby moving the aforementioned whole and placing the precast beam within the precast beam curing area. The first drive assembly can be an existing linear drive mechanism, as long as it can drive the two water tanks to move synchronously. The spray frame 4 spans above the precast beam 2, inside the multiple sheds 1, with both ends of the spray frame 4... The spray frame 4 is slidably connected to two water tanks 3 and driven by a second drive assembly to move along the length of the water tanks 3. The second drive assembly can be an existing linear drive mechanism, as long as it can drive the spray frame 4 to move along the length of the water tanks 3. Multiple nozzles are provided at intervals along the circumference of the inner side of the spray frame 4. The spray frame 4 is supplied with water from the water tanks 3. The water is sprayed evenly through the multiple nozzles and sprayed onto the precast beams 2 to spray and cure the precast beams 2. The water that is not absorbed by the precast beams 2 after spraying is guided back to the water tanks 3 through the support plate 5 that overlaps with the base 7. An elastic sealing strip is provided at the end of the support plate 5 that overlaps with the base 7 to achieve a sealed connection between the base 7 and the support plate 5.

[0026] This invention fixes water tanks under multiple scaffolds, slides the spray frame to the water tanks along their length, and connects the upper part of the water tanks to the side wall of the base via a support plate. This allows water not absorbed by the precast beams to flow back into the water tanks through the support plate when the spray frame moves along the length of the water tanks to perform cyclic spraying and curing. This enables the recycling of spraying water based on the existing structure of the precast beam yard, while preventing unabsorbed water from flowing randomly to the ground and causing the precast beam yard floor to become slippery.

[0027] Furthermore, in order to facilitate the adjustment of temperature and humidity in the precast beam curing area and prevent the spray water from overflowing, after the water tank is positioned, tarpaulins can be erected on multiple sheds 1 to form a semi-enclosed space in the precast beam curing area.

[0028] In another embodiment, such as Figure 1 , Figure 2 As shown, each shed 1 has reinforcing ribs 8 fixed on both sides of its top. Guide rods 9 are fixed on the reinforcing ribs 8 on the same side of the multiple sheds 1. The guide rods 9 are parallel to the water tank 3. A limiting groove is provided on the side of the guide rod 9 near the spray frame 4 along the length of the guide rod 9. The top of the spray frame 4 is slidably engaged with the limiting groove.

[0029] In the above embodiment, by fixing reinforcing ribs 8 on both sides of the top of each shed 1, the structural strength of the shed 1 is improved. At the same time, the reinforcing ribs 8 can provide stable support for the guide rod, so that the spray frame 4 can move stably along the length direction of the water tank 3 under the driving of the second drive assembly and the limiting and guiding action of the limiting slide.

[0030] In another embodiment, such as Figure 1 , Figure 5 As shown, at least one pair of guide blocks 10 are provided on the opposite two sides of the two water tanks 3 along their length direction. The opposite two sides of each pair of guide blocks 10 are inclined surfaces, and the spacing between each pair of guide blocks 10 increases sequentially along the moving direction of the water tanks 3.

[0031] In the above embodiment, by setting multiple pairs of guide blocks 10 on the opposite sides of the two water tanks 3, the forward direction of the water tanks 3 is guided by the contact between the inclined surface of the guide block 10 and the base 7 during the movement of the water tanks 3 driven by the first drive component, and the position of the water tanks 3 is adjusted to be symmetrically arranged on both sides of the base 7, which facilitates the subsequent overlapping and fixing of the receiving plate 5 and the base 7.

[0032] In another embodiment, such as Figures 1-3 As shown, the first drive assembly includes a support plate 11, which is fixedly mounted on the front or rear side wall of the water tank 3, and a first opening 12 is provided in the middle of the support plate 11; a mounting plate 13, which is a U-shaped plate, which is located below the support plate 11 and fixedly connected to it; a rotating wheel assembly 14, which is located inside the mounting plate 13 and rotatably connected to it; a first motor 15, which is located on one side of the first opening 12 on the support plate 11, and the output shaft of the first motor 15 drives the rotating wheel assembly 14 to rotate through a sprocket and chain drive; and a protective cover 16, which covers the first motor 15 and is detachably connected to the support plate 11.

[0033] In the above embodiment, the support plate 11 is used to support the fixed mounting plate 13 and the first motor 15. The mounting plate 13 is used to support the rotating wheel group 14. The first motor 15 drives the rotating wheel group to rotate through the sprocket and chain transmission assembly. The rotation of the rotating wheel group 14 drives the water tank 3 to move, so as to realize the movement of the water tank 3 through the first drive assembly. The protective cover 16 is used to protect the first motor.

[0034] In another embodiment, such as Figure 3As shown, the water tank 3 is provided with a first partition 17, which is vertically arranged and divides the water tank 3 into a collection tank 18 and a storage tank. The storage tank is provided with a second partition 19, which divides the storage tank into a return water tank 20 and a new water tank 21. The spray frame 4 moves along the length of the collection tank 18. The lower part of the first partition 17 is provided with a filter plate 22. The return water tank 20 and the new water tank 21 are connected by a first water pump 23. The new water tank 21 is provided with a second water pump 24, which is connected to the spray frame 4 and supplies water to the spray frame 4.

[0035] In the above embodiment, the water tank 3 is divided into a collection tank 18, a return water tank 20, and a new water tank 21 by the first partition 17 and the second partition 19. The spray frame 4 is set to move along the length of the collection tank 18 to achieve the recycling of spray water while avoiding contamination of the new water tank 21 by the return water. The collection tank 18 is used to collect the spray water that flows back through the receiving plate 5. The return water tank 20 is used to store the return water after filtration by the filter plate. When the water level of the return water is higher than the preset water level, the first water pump 23 introduces the return water in the return water tank 20 into the new water tank 21 to achieve the recycling of the return water. 21 is used to store new water and return water introduced by the first water pump 23. The new water tank 21 is provided with a water inlet, which is connected to an external water source through an external water pump. When the water level in the new water tank 21 is lower than the preset water level, water is added to the new water tank 21 through the external water pump. The water in the new water tank 21 is then pumped into the spray frame 4 through the second water pump 24 and the water inlet pipe (not shown) to supply water to the spray frame 4. Specifically, the water inlet pipe is a telescopic pipe and is movably installed in the collection box 18. One end of the water inlet pipe is connected to the spray frame 4, and the other end passes through the upper part of the first partition 17 and is connected to the outlet of the second water pump 24.

[0036] In another embodiment, such as Figure 3 As shown, the top surface of the collection box 18 is open and a sliding plate 25 is fixed along its length. The top surface of the sliding plate 25 is provided with a sliding groove. The end of the spray frame 4 is provided with a slider, which is slidably engaged with the sliding groove.

[0037] In the above embodiments, the spray frame 4 slides along the length of the collection box 18 through the slide plate 25, the slide groove and the slider, which has a simple structure and stable connection.

[0038] In another embodiment, such as Figure 3 As shown, the second drive assembly includes a rack 26 fixed to one side of the slide plate 25; a second motor 27 fixed to the spray frame 4 with its output end facing downward; and a drive gear 28 fixed to the output end of the second motor 27, which meshes with the rack 26.

[0039] In the above embodiment, by fixing the second motor 27 to the spray frame 4, the second motor 27 drives the drive gear 28 to rotate, causing the drive gear 28 to move along the rack 26, thereby driving the spray frame 4 to move along the length direction of the rack 26, so as to realize that the second drive component drives the spray frame 4 to slide along the length direction of the collection box 18.

[0040] In another embodiment, such as Figure 3 , Figure 4 As shown, the bottom of the collecting box 18 is provided with a pad 29, and the pad 29 is provided with a collecting groove 30 near the filter plate 22. A scraper 31 is provided above the pad 29, and a connecting plate 32 is fixed on the scraper 31. A connecting sleeve 33 is fixed on the connecting plate 32, and a connecting rod 34 is inserted into the connecting sleeve 33. The connecting rod 34 and the connecting sleeve 33 are slidably engaged. The top of the connecting rod 34 is connected to the output end of the second motor 27 through a bearing 35. Limiting rods 36 are provided on both sides of the connecting plate 32. The limiting rods 36 are slidably engaged with the guide groove 37 provided on the side wall of the collecting box 18. The guide groove 37 is a parallelogram groove, and one of the inclined sides of the guide groove 37 is opposite to the collecting groove 30 and located above the collecting groove 30.

[0041] In the above embodiment, a pad 29 and a collection groove 30 are provided at the bottom of the collection tank 18, and a scraper 31 is provided on the pad 29. The scraper 31 is connected to the output bearing of the second motor 27 through a connecting plate 32, a connecting sleeve 33, and a connecting rod 34. Limiting rods 36 are provided on both sides of the connecting plate 32, and a parallelogram-shaped guide groove 37 is provided on the side wall of the collection tank 18 to slide and engage with the limiting rods 36. The connecting rod 34 and the connecting sleeve 33 are configured to slide and engage vertically, so that the scraper 31 is driven by the second motor 27 to move closer to the water storage tank. When the scraper 31 moves to one side, it can contact the surface of the pad 29 to clean the surface of the pad 29 until the slag is scraped into the collection trough 30. When the second motor 27 drives the scraper 31 to move above the collection trough 30, under the action of the inclined side of the guide slide 37, the limiting rod 36 moves upward along the inclined side. The limiting rod 36 drives the connecting plate 32, and the connecting plate 32 drives the connecting sleeve 33 and the scraper 31 to move upward synchronously. The scraper 31 separates from the surface of the pad 29. When the second motor 27 moves to the end of the rack 26, the limiting rod 36 is located in the guide slide 30. At the apex of 7, the second motor 27 drives the scraper 31 to move away from the water storage tank. At this time, the scraper 31 remains separated from the pad 29 and does not contact the surface of the pad 29, so it will not scrape the slag on the pad 29 to the side away from the collecting trough 30. When the limiting rod 36 moves with the second motor 27 to the apex of the other side of the guide slide 37, under the action of the inclined side of the guide slide 37, the limiting rod 36 moves downward along the inclined side. The limiting rod 36 drives the connecting plate 32, and the connecting plate 32 drives the connecting sleeve 33 and the scraper to move downward synchronously until the scraper 31 and the pad 29 are separated. The plate 29 contacts the surface, and then the second motor 27 drives the scraper 31 to move towards the side closer to the water storage tank. The above actions are repeated to achieve the circulation and cleaning of the surface of the pad 29. The scraper 31, connecting plate 32, connecting sleeve 33 and connecting rod 34 do not interfere with the water inlet pipe during the movement with the second motor 27. Specifically, the water inlet pipe can be restricted to the side of the collection box 18 opposite to the second motor 27 and above the connecting plate 32 by limiting the position of the water inlet of the spray frame 4 and the position of the water inlet pipe passing through the first partition 17.

[0042] Furthermore, a damping rubber sleeve is provided between the connecting rod 34 and the connecting sleeve 33 to increase the friction between the connecting rod 34 and the connecting sleeve 35, so that the connecting rod 34 and the connecting sleeve 35 can only slide up and down when the limiting rod 36 is located on the inclined side of the guide groove 37.

[0043] Furthermore, a slag outlet is provided on one side of the collecting tank 30, and a slag outlet gate 39 is provided on the slag outlet to facilitate the removal of slag from the collecting tank.

[0044] Furthermore, reinforcing rods 38 are provided on both sides of the connecting rod 34. One end of the reinforcing rod 38 is fixedly connected to the connecting plate 32, and the other end is connected to the spline of the outer wall of the connecting rod 34 through a reinforcing sleeve, so as to improve the driving stability between the connecting rod and the connecting plate.

[0045] This invention also provides a method for curing precast beams, which uses the aforementioned precast beam yard curing system to cure precast beams, specifically including:

[0046] Step 1: Move the precast beam yard curing system to the precast beam to be cured using the first drive component;

[0047] Step 2: Add water to the new water tank 21 using an external water pump;

[0048] Step 3: Drive the receiving plate 5 to rotate by the third motor 6, so that the receiving plate 5 overlaps with the side wall of the base 7;

[0049] Step 4: Start the second water pump 24 and the second drive assembly at regular intervals to make the spray frame 4 reciprocate along the length of the collection box 18, spray water onto the surface of the precast beam 2, and perform spray curing on the precast beam 2. During the spray curing, the spray water that is not absorbed by the precast beam 2 and the scum on the surface of the precast beam 2 flow back into the collection box 18 through the receiving plate 5 and fall onto the pad plate 29. The water and scum on the pad plate 29 are further scraped into the collection tank 30 by the scraper 31. The water in the collection tank 30 enters the return water tank 20 after being filtered by the filter plate. When the water level in the return water tank 20 is higher than the preset water level, the return water in the return water tank 20 is introduced into the new water tank 21 by the first water pump 23 to realize the recycling of the return water.

[0050] Step 5: After the spray curing is completed, the precast beam yard curing system is moved to the new precast beam to be cured by the first drive component to carry out a new round of spray curing operation.

[0051] Furthermore, it also includes opening the slag discharge door after multiple rounds of spray curing operations to remove the slag collected in the collection tank, and at the same time using tools to scrape and wash the filter plates to prevent them from clogging.

[0052] The number of devices and processing capacity described herein are for simplification of the invention. Applications, modifications, and variations of the precast beam yard curing system and method of this invention will be readily apparent to those skilled in the art.

[0053] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
