Description

Technical Field

[0001] The invention relates to the technical field of concrete component curing equipment, and in particular to a stacking and spraying device for prefabricated concrete staircase components. Background Art

[0002] As the construction industry's requirements for construction efficiency, quality, and cost continue to rise, the use of prefabricated components in building structures has gradually become a significant development trend. Concrete stairs, an indispensable component of buildings, face numerous challenges with traditional on-site casting methods, including long construction periods, complex on-site management, and challenging quality control. To improve construction efficiency and ensure structural quality, the use of prefabricated concrete staircase components has emerged. Prefabricated concrete staircase components are prefabricated in a factory according to design requirements and then transported to the site for installation. This method avoids the complexity of pouring concrete in traditional construction, enabling the construction of stairs to be completed in a shorter timeframe while effectively improving quality consistency. Because prefabricated components are manufactured in a factory, they can fully utilize standardized production processes and be maintained in a relatively stable environment, ensuring their strength and stability.

[0003] The existing technology has the following technical problems in actual use:

[0004] Most of the existing prefabricated concrete stair components are stacked together and then separated by a wooden block. This stacking method may prevent moisture from fully penetrating during spraying due to the small gaps between them, thus affecting the spraying effect of the components. At the same time, due to the stacking together, some prefabricated components absorb excessive moisture, while others do not absorb enough moisture, thus affecting the quality of the prefabricated components. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems and provide a stacking spraying device for prefabricated concrete staircase components.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] The stacking mechanism includes a mobile rack arranged inside the stacking bin, a matching mechanism is arranged inside the mobile rack, two groups of matching mechanisms are symmetrically arranged, and at least five layers are provided. The matching mechanism includes a support frame fixedly installed on one side of the inner wall of the stacking bin, a matching frame is slidably installed inside the support frame, a support groove is provided on the top of the matching frame, a support block is slidably installed inside the matching frame, the support block extends to the top of the matching frame through the support groove, and a pushing block matching the support block is slidably installed inside the matching frame. The two groups of support frames are used to place prefabricated components.

[0009] The movable frame can move horizontally inside the stacking bin. The spray mechanism includes a humidity detector fixedly mounted on one side of the inner wall of the stacking bin. The humidity detectors are arranged in at least five groups. A plurality of atomizing heads are fixedly mounted on the inner wall of the stacking bin.

[0010] Furthermore, there are at least three groups of support grooves, and two groups of connecting blocks are provided inside the matching frame. The connecting blocks are located on both sides of the support block and are fixedly connected to the support block. The sides of the support block that match the pushing block are both set as inclined surfaces. A limiting plate is fixedly installed on the top of the support block, and the limiting plate is set as L-shaped. A support rod is fixedly installed between the matching frame and the movable frame.

[0011] Furthermore, spray plates are fixedly installed on both left and right sides of the inner wall of the stacking bin, and the opposite side of the spray plate is fixedly connected to the atomizing head, and the spray plate is set to a hollow structure.

[0012] Furthermore, a water collecting seat is fixedly installed on the bottom of the stacking bin, a water storage tank is fixedly installed on the top of the water collecting seat, and the water storage tank is located on one side of the stacking bin.

[0013] Furthermore, a collecting groove is provided inside the water collecting seat, and a driving water pump is fixedly installed inside the water storage tank, and one end of the driving water pump extends to the inside of the water collecting seat through the collecting groove.

[0014] Furthermore, a transmission pipe is fixedly installed on the surface of the stacking bin, the transmission pipe is connected to the spray plate, and a connecting pipe is fixedly connected between the water tank and the transmission pipe.

[0015] Furthermore, a moving wheel is rotatably mounted on the top of the moving frame, and a plurality of water collecting troughs are provided at the bottom of the stacking bin, and the stacking bin is connected to the water collecting seat through the water collecting troughs.

[0018] Furthermore, the humidity detector is electrically connected to the electric telescopic rod and the driving water pump.

[0022] 3. The stacking bin provided in the present invention can block the splashed water through the inner wall when spraying prefabricated components, and then flow down along the inner wall, so that part of the sprayed water is collected at the inner bottom of the stacking bin, and then collected by the water collection seat for recycling and reuse.

[0032] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] A stacking and spraying device for precast concrete stair components according to a preferred embodiment of the present invention will be described in detail below.

[0034] Example 1, as Figures 1-8 As shown, it includes a stacking bin 1, and a stacking mechanism 2 and a spraying mechanism 3 are provided inside the stacking bin 1;

[0035] The stacking mechanism 2 includes a mobile rack 21 arranged inside the stacking bin 1, and a matching mechanism 5 is arranged inside the mobile rack 21. The matching mechanism 5 is symmetrically arranged in two groups and is provided with at least five layers. The matching mechanism 5 includes a support frame 51 fixedly installed on one side of the inner wall of the stacking bin 1, and a matching frame 52 is slidably installed inside the support frame 51. A support groove 53 is opened on the top of the matching frame 52, and a support block 54 is slidably installed inside the matching frame 52. The support block 54 extends to the top of the matching frame 52 through the support groove 53. A pushing block 55 that cooperates with the support block 54 is slidably installed inside the matching frame 52. The two groups of support frames 51 are used to place prefabricated components 6;

[0036] The mobile frame 21 can move horizontally inside the stacking bin 1. The spray mechanism 3 includes a humidity detector 31 fixedly mounted on one side of the inner wall of the stacking bin 1. The humidity detectors 31 are arranged in at least five groups. A plurality of atomizing heads 32 are fixedly mounted on the inner wall of the stacking bin 1.

[0037] At the beginning of the spraying, the staff first pulls out the mobile rack 21, and then sequentially places the prefabricated components 6 on the surface of the matching frame 52 installed on the inner wall of the mobile rack 21, and then controls the pushing block 55 to move inward. During the movement, the pushing block 55 contacts the supporting block 54, and due to its shape setting, the supporting block 54 moves upward, lifting the prefabricated component 6, and then pushes the mobile rack 21 into the interior of the stacking bin 1. During the pushing process, the matching frame 52 is aligned with the supporting frame 51, and the matching frame 52 is inserted into the interior of the supporting frame 51. After the matching frame 52 completely enters the interior of the support frame 51, the staff then transports water to the atomizing head 32, and the atomizing head 32 sprays the water into atomized form on the surface of the prefabricated component 6. Since the support block 54 lifts the prefabricated component 6 and cooperates with the multiple groups of atomizing heads 32, the water mist can evenly contact the prefabricated component 6 for wetting. After the spraying is completed, the push block 55 is controlled to reset. After the push block 55 is reset, the prefabricated component 6 will fall to the surface of the support frame 51, and the spraying work on the prefabricated component 6 can be completed.

[0038] In the middle and late stages of spraying, the humidity detector 31 will monitor the humidity of each group of prefabricated components 6. When it is detected that the moisture content of a prefabricated component 6 is too high, the staff can control the corresponding push block 55 to move again, thereby lifting the prefabricated component 6 again through the support block 54. Then the staff can easily move the movable frame 21 out, thereby moving the prefabricated components 6 that do not need to be sprayed out, and only spraying the prefabricated components 6 that need to be sprayed;

[0039] By setting up the stacking mechanism 2, it can be ensured that all the prefabricated components 6 can be sprayed evenly in the initial stage of spraying, and that each component can receive sufficient moisture for maintenance. In the middle and late stages, the humidity detector 31 is used to detect and remove components with higher humidity, which can more effectively allocate water resources and avoid the waste of ineffective spraying time and water resources. At the same time, it can effectively prevent the humidity of a certain component from being too high. After it is removed, it can be prevented from continuing to absorb water, thereby avoiding the situation where the concrete strength does not meet the standard due to excessive moisture, thereby ensuring the quality of the prefabricated components 6. At the same time, the mobile rack 21 is used to facilitate the staff to operate the prefabricated components 6, and at the same time, they can be placed at a certain distance without stacking them, reducing the pressure on the lower prefabricated components 6.

[0040] Example 2, as Figures 1-8As shown, at least three groups of support grooves 53 are provided, and two groups of connecting blocks 56 are provided inside the matching frame 52. The connecting blocks 56 are located on both sides of the support block 54 and are fixedly connected to the support block 54. The side of the support block 54 that cooperates with the push block 55 is set as an inclined surface. A limit plate 57 is fixedly installed on the top of the support block 54. The limit plate 57 is set as an L-shape. A support rod is fixedly installed between the matching frame 52 and the movable frame 21. Spray plates 33 are fixedly installed on both sides of the inner wall of the stacking bin 1. The opposite side of the spray plate 33 is fixedly connected to the atomizing head 32, and the spray plate 33 is set as a hollow structure.

[0041] When the pushing block 55 moves toward one side of the supporting block 54, due to the inclined surface provided thereon, they can cooperate with each other to push the supporting block 54 upward, thereby driving the limiting plate 57 to contact both sides of the prefabricated component 6, thereby lifting the prefabricated component 6, and then the water is transported to the spray plate 33 by the provided water pump, sprayed through the atomizing head 32, and then evenly sprayed on the surface of the prefabricated component 6. At the same time, since the shape of the prefabricated component 6 is set at a certain angle, the sprayed water is very likely to gather in these potholes, thereby causing a certain part of the prefabricated component 6 to be over-wetted, thereby causing damage to the prefabricated component 6. At this time, the staff only needs to control the moving distance of the pushing block 55 on one side to adjust the height of the prefabricated component 6 pushed by the supporting block 54. The farther the distance, the higher the height. On the contrary, the prefabricated component 6 is made to present a certain tilt angle, so that the gathered water can flow out of the potholes. At the same time, the limiting plate 57 is provided, because of its L-shaped shape, it can play a certain limiting role on both sides of the prefabricated component 6 to prevent it from being offset due to the tilt of one side.

[0042] The support blocks 54 are provided to lift up both sides of the prefabricated component 6 for spraying. At the same time, after the spraying is completed, the height of the support blocks 54 is controlled to make one side of the prefabricated component 6 higher and the other side lower, so that it is tilted to a certain extent. The water accumulated in the potholes on the surface of the prefabricated component 6 during spraying is naturally guided out, preventing the occurrence of water accumulation and avoiding uneven concrete curing due to water retention in the potholes.

[0043] Example 3, as Figures 1-8 As shown, a water collecting seat 34 is fixedly installed at the bottom of the stacking bin 1, a water storage tank 35 is fixedly installed on the top of the water collecting seat 34, the water storage tank 35 is located on one side of the stacking bin 1, a collecting tank is opened inside the water collecting seat 34, a driving water pump is fixedly installed inside the water storage tank 35, one end of the driving water pump extends to the inside of the water collecting seat 34 through the collecting tank, a transmission pipe 7 is fixedly installed on the surface of the stacking bin 1, the transmission pipe 7 is connected to the spray plate 33, and a connecting pipe 8 is fixedly connected between the water storage tank 35 and the transmission pipe 7;

[0044] When the prefabricated component 6 needs to be sprayed, the output end of the water pump driven inside the water storage tank 35 transports the water inside it to the transmission pipe 7 through the connecting pipe 8, and then sprays it out from the atomizing head 32 through the transmission pipe 7. During the spraying process, since the work is carried out inside the stacking bin 1, part of the sprayed water will contact the inner wall of the stacking bin 1 and then flow down along the inner wall, so that part of the sprayed water is collected at the inner bottom of the stacking bin 1, and then collected by the water collecting seat 34 for recycling and reuse;

[0045] The stacking bin 1 is configured to block the splashed water through the inner wall when spraying the prefabricated components 6, and then flow down along the inner wall, so that part of the sprayed water is collected at the inner bottom of the stacking bin 1, and then collected by the water collection seat 34 for recycling and reuse.

[0046] Example 4, as Figures 1-8 As shown, the top of the mobile frame 21 is rotatably mounted with a moving wheel 9, the bottom of the stacking bin 1 is provided with a plurality of water collecting grooves 10, the stacking bin 1 is connected to the water collecting seat 34 through the water collecting grooves 10, and the inner wall of the matching frame 52 is fixedly mounted with an electric telescopic rod 11, and the output end of the electric telescopic rod 11 is fixedly connected to the push block 55 on one side;

[0047] The water collecting trough 10 provided can allow the water accumulated at the bottom of the stacking bin 1 to flow from the water collecting trough 10 into the water collecting seat 34 for collection, thereby collecting and recycling the excess water and avoiding water waste.

[0048] Example 5, as Figures 1-8 As shown, the humidity detector 31 is positioned facing the prefabricated component 6, a slide rail 12 is fixedly installed on one side of the stacking bin 1, and a sealed door 4 is slidably installed on one side of the stacking bin 1 via the slide rail 12. Two sets of sealed doors 4 are symmetrically arranged, and the humidity detector 31 is electrically connected to the electric telescopic rod 11 and the driving water pump.

[0049] The provided slide rail 12 allows the sealed door 4 to slide inside the sealed door 4, thereby sealing the stacking bin 1 and preventing the prefabricated components 6 from being exposed to sunlight and causing cracks.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
