Description

Technical Field

[0001] This utility model relates to the technical field of precast beam curing, and in particular to a precast beam spray curing device. Background Technology

[0002] Spray curing of precast beams is an efficient way to keep precast beams moist. By continuously or intermittently spraying water mist onto the surface of the beam, the concrete is kept in a moist environment. Its core is to use the moist cover formed by uniform spraying to ensure that the cement is fully hydrated to promote strength growth. At the same time, the evaporation of water removes some heat, which helps to control the temperature difference between the inside and outside of the beam and reduce the risk of drying shrinkage cracks.

[0003] Patent CN218429044U discloses a spray curing device for precast beam yards, including a water tank, a water injection pipe, a first water pump, a water delivery pipe, a support, a side plate, a top plate, a bottom plate, nozzles, a water collection pipe, a water collection pipe, a return pipe, and a second water pump. The water tank is equipped with the water injection pipe, the first water pump, and the second water pump. A support is fixedly connected to the top. The first water pump is connected to the water collection pipe through the return pipe, and the water collection pipe is connected to the water collection pipe. The output end of the second water pump is fixedly connected to the water delivery pipe, which is connected to the support. The support is connected to the side plate. A top plate is connected above the side plate, and a bottom plate is connected below it. Nozzles are fixedly connected to the inner sides of the side plate, the top plate, and the bottom plate. The device is arranged opposite to each other on both sides of the precast beam body. It improves the utilization rate of water resources during spray curing, meets the requirements of energy conservation and environmental protection, and simultaneously achieves spray curing of the outer wall of the precast beam body, effectively expanding the spray curing range.

[0004] Existing technologies have certain limitations: on the one hand, spraying devices need to be installed on both sides of the precast beam to achieve comprehensive curing, which leads to higher operating costs for the spraying curing devices; on the other hand, the spraying curing devices are fixed in position and cannot be moved along the length of the precast beam, while precast beams are usually quite long. To achieve full length coverage, a spraying device needs to be installed at intervals, which further increases the operating costs. Therefore, it is necessary to provide a precast beam spraying curing device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a precast beam spray curing device.

[0006] This utility model provides a precast beam spray curing device, including a water tank. A movable component is installed at the bottom of the water tank. A support rod is fixedly connected to one side of the top of the water tank. One end of the support rod is fixedly connected to an installation box. A delivery pump is fixedly installed on the top of the water tank. The inlet end of the delivery pump is connected to a first connecting pipe, and the outlet end of the delivery pump is connected to a second connecting pipe. One end of the second connecting pipe extends into the installation box and is fixedly installed with a rotating joint. A vertical pipe is fixedly installed at the bottom end of the rotating joint. The vertical pipe is rotatably connected to the installation box. The bottom end of the vertical pipe extends to the bottom of the installation box and is fixedly fitted with an upper flange. A spray component is installed on the upper flange. An adjusting motor is fixedly installed inside the installation box. A worm gear is fixedly connected to the rotating end of the adjusting motor. A worm wheel is fixedly fitted on the outside of the vertical pipe, and the worm wheel meshes with the worm gear.

[0007] Preferably, the spray assembly includes a spray pipe, a lower flange is fixedly fitted at the top of the spray pipe, and a plurality of spray heads communicating with the interior are fixedly installed at equal intervals on the pipe wall of the spray pipe. A plurality of bolt holes are longitudinally through the lower flange and the upper flange, and the lower flange and the upper flange are fixedly connected by bolts.

[0008] Preferably, the moving component includes two tracks symmetrically arranged. Two horizontal shafts are symmetrically arranged below the water tank. Two symmetrically arranged side plates are rotatably sleeved on the outer side of the horizontal shafts via bearings. The top of the side plates is fixedly connected to the bottom of the water tank. Two rotating wheels are symmetrically fixedly sleeved on the outer side of the horizontal shafts. The two rotating wheels are arranged one-to-one with the two tracks. The rotating wheels are rotatably arranged on the tracks. A drive motor is fixedly installed on the side wall of one of the side plates. One of the horizontal shafts is fixedly connected to the rotating end of the drive motor.

[0009] Preferably, the bottom end of the first connecting pipe extends into the lower inner part of the water tank.

[0010] Preferably, the track has an inverted "T" shaped cross section, and the wheel has a groove that matches the track to prevent the wheel from detaching from the track when it moves.

[0011] Preferably, the water tank is provided with a water inlet at the top.

[0012] Compared with related technologies, the precast beam spray curing device provided by this utility model has the following beneficial effects:

[0013] 1. In the spray assembly, several spray heads are installed at equal intervals on the wall of the spray pipe, with the outlet end of the spray head facing the precast beam. The delivery pump steadily delivers water from the water tank to the spray pipe through the first connecting pipe, the second connecting pipe, and the vertical pipe. Finally, the water is evenly sprayed onto the surface of the precast beam through the spray heads to ensure uniform curing. When the motor is working, the vertical pipe and the spray assembly are rotated 180° through the meshing transmission of the worm gear and worm wheel, so that the spray assembly is switched from one side of the precast beam to the other side. With the movement of the moving component, comprehensive spray curing of both sides of the precast beam can be achieved. It is not necessary to set up spray curing devices on both sides of the precast beam, which saves costs and is convenient to use.

[0014] 2. The lower flange of the spray assembly and the upper flange of the vertical pipe are fixedly connected by bolts and bolt holes. The two can be separated by removing the bolts, which facilitates the replacement of spray assemblies of different specifications to adapt to the spray curing of precast beams of different specifications and improve the versatility of the device.

[0015] 3. In the moving component, the drive motor drives the horizontal shaft and the rotating wheel to rotate. The rotating wheel rolls along the track.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] Please refer to the following: Figures 1 to 4 A precast beam spray curing device includes a precast beam and a water tank 2. A movable component 3 is installed at the bottom of the water tank 2, and a water inlet is provided at the top of the water tank 2. A support rod 4 is fixedly connected to one side of the top of the water tank 2. One end of the support rod 4 is fixedly connected to an installation box 10. A delivery pump 5 is fixedly installed at the top of the water tank 2. The water inlet of the delivery pump 5 is connected to a first connecting pipe 6, and the water outlet of the delivery pump 5 is connected to a second connecting pipe 7. One end of the second connecting pipe 7 extends into the installation box 10 and is fixedly installed with a rotating joint 15. A vertical pipe 8 is fixedly installed at the bottom of the rotating joint 15. The vertical pipe 8 is rotatably connected to the installation box 10. The bottom end of the vertical pipe 8 extends to the bottom of the installation box 10 and is fixedly fitted with an upper flange 12. A spray component 1 is installed on the upper flange 12. An adjusting motor 14 is fixedly installed inside the installation box 10. A worm gear 11 is fixedly connected to the rotating end of the adjusting motor 14. A worm wheel 9 is fixedly fitted on the outside of the vertical pipe 8, and the worm wheel 9 meshes with the worm gear 11.

[0026] In the above, the water tank 2 is used to store the water required for spray curing. The moving component 3 drives the device to move, realizing the curing of different positions of the precast beam. The support rod 4 provides stable support for the mounting box 10. The delivery pump 5 draws water from the water tank 2 through the first connecting pipe 6, and delivers it to the spray assembly 1 through the second connecting pipe 7, the rotating joint 15, and the vertical pipe 8 to provide power for spraying. When the regulating motor 14 is working, it drives the vertical pipe 8 to rotate through the meshing transmission of the worm gear 11 and the worm wheel 9, thereby realizing the rotation of the spray assembly 1. The upper flange 12 is used to connect the spray assembly 1. By adjusting the motor 14, the rotation of the spray assembly 1 is controlled to meet the curing needs of both sides of the precast beam and improve the comprehensiveness of the curing.

[0027] Furthermore, the spray assembly 1 includes a spray pipe 101, with a lower flange 103 fixedly fitted at the top end of the spray pipe 101. Several spray heads 102, communicating with the interior of the spray pipe 101, are fixedly installed at equal intervals on the pipe wall of the spray pipe 101. The outlet end of the spray head 102 faces one side of the precast beam. Several bolt holes 13 are longitudinally opened on the lower flange 103 and the upper flange 12. The lower flange 103 and the upper flange 12 are fixedly connected by bolts 16. A rubber sealing ring is provided between the lower flange 103 and the upper flange 12 to improve the sealing performance. The bolt holes 13 are used for the bolts 16 to pass through.

[0028] In the above-mentioned spray assembly 1, the spray pipe 101 provides a channel for water flow, and the spray head 102 sprays water evenly onto the surface of the precast beam to ensure uniform curing. The lower flange 103 and the upper flange 12 are fixedly connected by bolts 16 and bolt holes 13, which facilitates the installation and disassembly of the spray assembly 1. The rubber sealing ring can enhance the sealing of the connection between the lower flange 103 and the upper flange 12 to prevent water leakage during water supply. This not only achieves uniform spraying of the precast beam, but also allows for easy replacement of spray assemblies 1 of different specifications to adapt to precast beams of different shapes or sizes, thus improving the versatility of the device.

[0029] Example 2

[0030] For further details, please refer to [link / reference]. Figures 1 to 6 Based on Embodiment 1, the moving component 3 includes a track 301, the length of which is greater than the length of the precast beam. Two tracks 301 are symmetrically arranged. Two horizontal shafts 302 are symmetrically arranged below the water tank 2. Two symmetrically arranged side plates 305 are rotatably sleeved on the outer side of the horizontal shafts 302 through bearings. The top of the side plates 305 is fixedly connected to the bottom of the water tank 2. Two rotating wheels 303 are symmetrically fixedly sleeved on the outer side of the horizontal shafts 302. The two rotating wheels 303 are arranged one-to-one with the two tracks 301. The rotating wheels 303 are rotatably arranged on the track 301. A drive motor 304 is fixedly installed on the side wall of one of the side plates 305. One of the horizontal shafts 302 is fixedly connected to the rotating end of the drive motor 304. The drive motor 304, the delivery pump 5, and the regulating motor 14 are all electrically connected to an external control switch through wires. The drive motor 304, the delivery pump 5, and the regulating motor 14 are controlled to work by the external control switch.

[0031] In the above-mentioned moving component 3, two symmetrical tracks 301 provide guidance for the movement of the rotating wheel 303. The horizontal shaft 302 is rotatably connected to the side plate 305 through bearings. The side plate 305 connects the horizontal shaft 302 to the water tank 2 to ensure structural stability. When the drive motor 304 is working, it drives the horizontal shaft 302 and the rotating wheel 303 to rotate, causing the rotating wheel 303 to roll along the track 301, thereby driving the water tank 2 and the entire device to move. The external control switch is used to control the operation of the drive motor 304, the delivery pump 5 and the regulating motor 14.

[0032] Furthermore, the bottom end of the first connecting pipe 6 extends into the lower inner part of the water tank 2.

[0033] In the above, the bottom end of the first connecting pipe 6 extends into the lower part of the inner side of the water tank 2, which can extract water from the water tank 2 to the maximum extent and reduce the water residue at the bottom of the water tank 2.

[0034] Furthermore, the cross-section of the track 301 is an inverted "T" shape, and the wheel 303 is provided with a groove that matches the track 301 to prevent the wheel 303 from detaching from the track 301 when it moves.

[0035] In the above, the inverted "T"-shaped track 301 and the groove of the rotating wheel 303 cooperate with each other to form a lateral limit on the rotating wheel 303, effectively preventing the rotating wheel 303 from leaving the track 301 during the rolling process.

[0036] The working principle of the precast beam spray curing device provided by this utility model is as follows:

[0037] In use, the track 301 is fixedly installed on the ground, and water is added to the water tank 2 through the inlet for spraying and curing the precast beams. Figure 1 As shown, the precast beam is located on one side of the precast beam spray curing device. The shape of the spray pipe 101 is adapted to the shape of the precast beam. The drive motor 304 and the delivery pump 5 are started. The drive motor 304 drives the connected horizontal shaft 302 to rotate, which in turn drives the rotating wheel 303 to rotate, causing the wheel 303 to roll on the track 301. The rolling of the wheel 303 drives the water tank 2, causing the spray assembly 1 to move along the length of the precast beam. The delivery pump 5 operates, drawing water from the water tank 2 through the first connecting pipe 6 and delivering it to the vertical pipe 8 through the second connecting pipe 7. The water then enters the spray pipe 101 and is finally sprayed onto the precast beam through the spray head 102, thus performing spray curing on the precast beam. After the spray assembly 1 finishes spraying one side of the precast beam, the adjusting motor 14 is started. The adjusting motor 14 drives the worm gear 11 to rotate, which in turn drives the worm wheel 9 to rotate. The worm wheel 9 then drives the vertical pipe 8 to rotate the spray assembly 1 180°. Figure 6 As shown, the spray assembly 1 is switched from one side of the precast beam to the other side, and then the rotating end of the drive motor 304 is started to rotate in the opposite direction, causing the water tank 2 to move in the opposite direction back to the initial position. During the movement, the spray head 102 in the spray assembly 1 sprays water to the other side of the precast beam, thereby realizing the spray curing of the precast beam. By removing the bolt 16, the lower flange 103 and the upper flange 12 can be separated, so that the spray assembly 1 can be easily disassembled and replaced. Different spray assemblies 1 can be replaced to adapt to the spray curing of different precast beams.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
