Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, specifically to a foundation slab concrete curing device. Background Technology

[0002] The foundation slab concrete is the bottommost layer of concrete in a building, directly in contact with the soil or foundation. After pouring, the concrete should be kept moist within 12 hours. In hot, dry, or windy weather, it should be covered and kept moist beforehand. During the curing period, the concrete surface should be kept continuously moist, avoiding alternating wet and dry conditions. This can be achieved through methods such as watering, covering with plastic film, geotextile, or spraying curing agents. The curing time for ordinary concrete should be no less than 7 days, while the curing time for concrete with retarders, impermeable concrete, and large-volume concrete should be no less than 14 days. In winter construction, insulation measures should be taken to control the temperature difference between the inside and outside of the concrete to no more than 25°C to prevent freezing and temperature cracks.

[0003] When curing concrete slabs, water sprayed from curing equipment is applied to the concrete surface to keep it moist during curing, thus ensuring the quality of the concrete construction. However, current curing equipment has a very limited spray range, requiring workers to manually adjust the spray direction constantly. It cannot automatically change the spray position or achieve a larger spray range. To address these technical shortcomings, a concrete slab curing device is provided to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a foundation concrete curing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A concrete curing device for foundation slabs includes a movable frame. A pair of lifting blocks are vertically slidably mounted on the movable frame. Horizontally arranged guide beams are fixed on the two lifting blocks. A sliding frame is sleeved on the guide beams. A sliding drive assembly for driving the sliding frame to slide relative to the guide beams is installed on the sliding frame. A vertically arranged hollow shaft is rotatably mounted on the sliding frame. A water collection tray is installed at the lower end of the hollow shaft. A connecting pipe communicating with the upper end of the hollow shaft is installed on the sliding frame. A plurality of radially extending radial pipes are installed on the side wall of the water collection tray. A spraying assembly is installed on each radial pipe. An automatic adjustment assembly for driving the spraying assembly to reciprocate relative to the radial pipes is installed at the bottom of the sliding frame.

[0006] As an improvement of the present invention: a motor is fixed to the top of the sliding frame, a main gear is fixed coaxially to the output shaft of the motor, and a secondary gear that meshes with the main gear is fixedly sleeved on the hollow shaft.

[0007] As an improvement of the present invention: the sliding drive assembly includes a worm gear fixed coaxially with the hollow shaft, a worm wheel meshing with the worm gear is rotatably mounted on the sliding frame, a traveling gear is coaxially fixed on the worm wheel, and a rack meshing with the traveling gear is fixed on the guide beam.

[0008] As an improvement of the present invention: two parallel wheel grooves are provided on the top of the guide beam, and guide wheels adapted to the wheel grooves are rotatably mounted on the sliding frame.

[0009] As an improvement of the present invention: the spray assembly includes a spray pipe slidably sleeved on the radial pipe through a sealing assembly, a plurality of evenly distributed nozzles are connected and installed at the bottom of the spray pipe, a sliding sleeve is slidably sleeved on the hollow shaft, a lifting sleeve is rotatably installed on the sliding sleeve, a transmission rod is hinged between the lifting sleeve and the spray pipe, and a limiting plate is fixed on the sliding sleeve and rotatably embedded in the lifting sleeve.

[0010] As an improvement of the present invention: the automatic adjustment component includes a rotating wheel rotatably mounted at the bottom of the sliding frame, a pull rod eccentrically hinged to the rotating wheel, the lower end of the pull rod hinged to the sliding sleeve, bevel gears coaxially fixed on both the hollow shaft and the rotating wheel, the two bevel gears meshing and connected, a rotating sleeve plate rotatably mounted on the lower end of the sliding sleeve, and a support spring fixed between the rotating sleeve plate and the water collection plate.

[0011] As an improvement of the present invention: the sealing assembly includes a piston sleeve plate fixedly sleeved on the end of the radial pipe, the piston sleeve plate being slidably installed inside the spray pipe, and a spring ring sleeved on the radial pipe being fixed between the piston sleeve plate and the spray pipe.

[0012] As an improvement of the present invention: two coaxially fixed adjusting screws with opposite thread directions are rotatably mounted on the movable frame. Each adjusting screw is threaded with an adjusting sleeve block that is slidably adapted to the movable frame. An adjusting rod is hinged between the adjusting sleeve block and the lifting block.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a hollow shaft to drive the water collection plate to rotate, which causes the radial pipe and spraying assembly to rotate synchronously. The spray water is dispersed and sprayed out by the nozzles and falls onto the concrete surface of the base plate for curing. The sliding frame can slide linearly along the guide beam and adjust the spraying area, so that the area of ​​spray water sprayed by the nozzles is automatically adjusted, which greatly improves the operation efficiency of concrete spray curing.

[0014] 2. The rotating wheel in this invention can drive the sliding sleeve to move vertically back and forth relative to the hollow shaft through the pull rod, so that the lifting sleeve can move vertically back and forth. The lifting sleeve pulls the spray pipe to slide back and forth relative to the radial pipe through the transmission rod, so that the nozzle has a larger spraying working range. Combined with the nozzle rotating around the center of the water collection plate, a large-area spraying of spray water is realized, and the spray curing effect of the base slab concrete is significantly improved.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0018] First embodiment: Please refer to the appendix Figure 1 - Appendix Figure 7 A concrete curing device for foundation slabs includes a movable frame 1. A pair of lifting blocks 4 are vertically slidably mounted on the movable frame 1. A horizontally arranged guide rail beam 2 is fixed on the two lifting blocks 4. A sliding frame 3 is sleeved on the guide rail beam 2. A sliding drive assembly for driving the sliding frame 3 to slide relative to the guide rail beam 2 is installed on the sliding frame 3. A vertically arranged hollow shaft 12 is rotatably mounted on the sliding frame 3. A water collection tray 6 is installed at the lower end of the hollow shaft 12. A pipe 14 communicating with the upper end of the hollow shaft 12 is installed on the sliding frame 3. Several radially extending radial pipes 24 are installed on the side wall of the water collection tray 6. A spraying assembly is installed on each radial pipe 24. An automatic adjustment assembly for driving the spraying assembly to reciprocate relative to the radial pipe 24 is installed at the bottom of the sliding frame 3.

[0019] When using this curing equipment to cure the foundation concrete, the connecting pipe 14 is connected to an external water source. A water pump pumps the spray water, which enters the hollow shaft 12 through the connecting pipe 14. The spray water then collects in the collection tray 6 and is dispersed through multiple radial pipes 24. Finally, the spray water is dispersed from the spray assembly and discharged onto the foundation concrete, achieving spray curing of the foundation concrete. The movable frame 1 can be moved to change the spray area, ensuring that the spray water reaches different areas of the foundation concrete and that the foundation concrete is thoroughly sprayed.

[0020] A motor 8 is fixed to the top of the sliding frame 3 of this curing equipment. A main gear 10 is coaxially fixed to the output shaft of the motor 8, and a secondary gear 11 that meshes with the main gear 10 is fixedly sleeved on the hollow shaft 12. The motor 8 can drive the main gear 10 to rotate, the main gear 10 drives the secondary gear 11 to rotate, the secondary gear 11 drives the hollow shaft 12 to rotate, and the hollow shaft 12 drives the water collection plate 6 and the radial pipe 24 to rotate. At this time, multiple spraying components can rotate around the central axis of the hollow shaft 12, thereby realizing the effect of rotational spraying, which greatly increases the spraying range of the sprayed water and effectively improves the efficiency of concrete spray curing operation.

[0021] The sliding drive assembly of this maintenance equipment includes a worm gear 27 coaxially fixed with the hollow shaft 12, a worm wheel 18 rotatably mounted on the sliding frame 3 that meshes with the worm gear 27, a traveling gear 25 coaxially fixed on the worm wheel 18, and a rack 15 meshing with the traveling gear 25 fixed on the guide beam 2.

[0022] With the above settings, after the motor 8 starts, the hollow shaft 12 rotates, driving the worm 27 to rotate. The worm gear 18 meshing with the worm 27 rotates, and the worm gear 18 drives the traveling gear 25 to rotate. Since the traveling gear 25 is meshed with the rack 15, the sliding frame 3 can slide linearly relative to the guide beam 2, allowing the spraying position of the spraying assembly to be linearly adjusted. By controlling the output shaft of the motor 8 to rotate clockwise and counterclockwise alternately, the traveling gear 25 can rotate clockwise and counterclockwise alternately, thereby realizing the reciprocating sliding of the sliding frame 3 relative to the guide beam 2, achieving the automatic adjustment effect of the spraying area, and greatly improving the efficiency of concrete spraying and curing.

[0023] Two parallel wheel grooves 31 are provided on the top of the guide beam 2. Guide wheels 9 that are adapted to the wheel grooves 31 are rotatably installed on the sliding frame 3. During the linear sliding of the sliding frame 3, the guide wheels 9 roll in the wheel grooves 31 to support and guide the sliding frame 3, ensuring the smoothness of the sliding frame 3.

[0024] Second embodiment: Please refer to the appendix Figure 1 - Appendix Figure 7 Based on the first embodiment, the spray assembly of this maintenance equipment includes a spray pipe 7 that is slidably sleeved on a radial pipe 24 via a sealing assembly. Several evenly distributed nozzles 21 are connected to the bottom of the spray pipe 7. A sliding sleeve 22 is slidably sleeved on the hollow shaft 12. A lifting sleeve 32 is rotatably mounted on the sliding sleeve 22. A transmission rod 23 is hinged between the lifting sleeve 32 and the spray pipe 7. A limiting plate 19 is fixed on the sliding sleeve 22 and rotatably embedded in the lifting sleeve 32.

[0025] The spray water in the water collection pan 6 enters the spray pipe 7 through the radial pipe 24, and then the spray liquid is dispersed and sprayed out from multiple nozzles 21. Due to the sealing component, the radial pipe 24 and the spray pipe 7 have a good sealing effect. Under the action of the automatic adjustment component, the radial pipe 24 can slide back and forth relative to the spray pipe 7. The rotation radius of the spraying process is automatically adjusted, which can effectively improve the spraying range and achieve efficient spraying in the curing process of the base slab concrete.

[0026] Specifically, the automatic adjustment component includes a rotating wheel 13 rotatably mounted at the bottom of the sliding frame 3, a pull rod 20 eccentrically hinged to the rotating wheel 13, the lower end of the pull rod 20 hinged to the sliding sleeve 22, bevel gears 28 coaxially fixed on both the hollow shaft 12 and the rotating wheel 13, the two bevel gears 28 meshing and connected, a rotating sleeve 30 rotatably mounted on the lower end of the sliding sleeve 22, and a support spring 29 fixed between the rotating sleeve 30 and the water collection plate 6.

[0027] With the above structural configuration, when the hollow shaft 12 rotates, the hollow shaft 12 drives the bevel gear 28 on it to rotate, the bevel gear 28 drives another bevel gear 28 meshing with it to rotate, the bevel gear 28 drives the rotating wheel 13 fixed on the same axis to rotate, the rotating wheel 13 pulls the sliding sleeve 22 to move vertically back and forth relative to the hollow shaft 12 through the pull rod 20. During this process, the sliding sleeve 22 is driven to move vertically back and forth through the limiting plate 19, and the lifting sleeve 32 drives the spray pipe 7 to slide back and forth relative to the radial pipe 24 through the transmission rod 23. The nozzle 21 at the bottom of the spray pipe 7 can not only rotate around the central axis of the hollow shaft 12, but also slide radially back and forth relative to the water collection plate 6, and the spraying range of the spray water is further improved.

[0028] In addition, the sealing assembly of this device includes a piston sleeve 33 fixedly fitted to the end of the radial pipe 24. The piston sleeve 33 is slidably installed inside the spray pipe 7, and a spring ring 26 fitted on the radial pipe 24 is fixed between the piston sleeve 33 and the spray pipe 7. During the rotation of the spray pipe 7 relative to the radial pipe 24, the piston sleeve 33 slides and seals against the inner wall of the spray pipe 7, ensuring an effective sealing effect during the relative sliding process of the spray pipe 7 and the radial pipe 24, and improving the reliability of this maintenance equipment during spray maintenance.

[0029] In addition, two coaxially fixed adjusting screws 16 with opposite thread directions are rotatably mounted on the movable frame 1. Each adjusting screw 16 is threaded with an adjusting sleeve 17 that is slidably adapted to the movable frame 1. An adjusting rod 5 is hinged between the adjusting sleeve 17 and the lifting block 4.

[0030] Rotating the adjusting screw 16 drives the two adjusting sleeves 17 to slide relative to the moving frame 1. The two adjusting sleeves 17 move towards or away from each other. The adjusting sleeves 17 drive the lifting block 4 to move vertically relative to the moving frame 1 through the water collection plate 6. At this time, the lifting block 4 drives the guide rail beam 2 to move vertically up and down. When the two adjusting sleeves 17 move towards each other, the height of the guide rail beam 2 is raised. When the two adjusting sleeves 17 move away from each other, the height of the guide rail beam 2 is lowered. This allows for flexible adjustment of the height of the guide rail beam 2 and the sliding frame 3, ensuring that the spray water from the nozzle 21 can be sprayed more comprehensively onto the concrete base plate to achieve the curing effect.

[0031] In summary, this invention uses a hollow shaft 12 to drive the water collection tray 6 to rotate, causing the radial pipe 24 and the spraying assembly to rotate synchronously. The spray water is dispersed and sprayed out by the nozzles 21, landing on the concrete surface of the base slab for curing. The sliding frame 3 can slide linearly along the guide beam 2 and adjust the spraying area, resulting in automatic adjustment of the spray water area from the nozzles 21, greatly improving the operational efficiency of concrete spraying curing. The rotating wheel 13 in this invention can drive the sliding sleeve 22 to reciprocate vertically relative to the hollow shaft 12 via the pull rod 20, allowing the lifting sleeve 32 to reciprocate vertically. The lifting sleeve 32, through the transmission rod 23, pulls the spray pipe 7 to slide back and forth relative to the radial pipe 24, giving the nozzles 21 a larger spraying range. Combined with the rotation of the nozzles 21 around the center of the water collection tray 6, a large-area spraying of water is achieved, significantly improving the curing effect of the base slab concrete spraying.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
