Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, in particular to concrete curing equipment for building construction. Background Art

[0002] Concrete curing equipment is equipment used to adjust and maintain the concrete curing environment (such as temperature, humidity, etc.) to ensure that the concrete specimens or structures can achieve optimal performance during the hardening process.

[0003] Concrete curing is an important part of concrete construction. Special curing equipment is used to cure the newly poured concrete so that it hardens under specified temperature and humidity conditions to achieve the strength and other properties required by the design. This process usually includes two methods: natural curing and steam curing. Natural curing refers to the moisturizing measures taken for concrete under natural conditions, usually involving watering, covering, etc. to keep the concrete surface moist to prevent it from drying out too quickly and forming cracks.

[0004] Concrete maintenance usually uses plastic film to cover the concrete surface to isolate the concrete from moisture loss. When using these plastic films, workers need to manually take a piece of plastic film and cover it on the concrete. This method requires a lot of time and manpower. At the same time, during the manual removal process, if the operation is improper, dust, soil or other pollutants may be brought into the concrete surface, thereby affecting the quality and appearance of the concrete. If at the construction site, manually taking a piece of film and walking to the concrete that needs to be cured may involve high-altitude operations or interactions with other construction equipment on the way, thereby increasing the risk of injury to operators. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention stores the plastic film by means of the baffle plate and the placement plate on the L-shaped support plate, thereby providing a relatively closed environment for the plastic film, effectively isolating the external moisture and dust, thereby protecting the plastic film from moisture and dust. At the same time, when the plastic film needs to be taken, it is only necessary to move the entire device to the side of the concrete, and pull the plastic film out of the placement bin by rotating the L-shaped support plate. This method can achieve the use and take-out, and can also avoid the risk of interaction with other construction equipment during the taking process, causing the risk of injury to the workers;

[0020] 2. At the same time, when the plastic film moves from the placement plate, the flow channel at the hose will be opened, so that when it is needed, the water stored in the water tank will be transported to the liquid inlet plate. When not in use, the water in the water tank will not seep out, so that the water reaches the liquid inlet plate through the delivery pipe and wets the lower surface of the plastic film. When the plastic film is taken out and covered on the concrete with water, it can ensure that there will be some water on the surface of the concrete, so that the overall shape of the concrete remains intact without cracking, thereby increasing the maintenance effect of the entire concrete;

[0021] 3. After taking out the required plastic film, you can pull the cutting knife to cut the plastic film, and cover the entire plastic film on the concrete surface, avoiding the waste of plastic film. At the same time, during the cutting process, the inner cutting knife set inside the cutting knife is moved, which can make the entire cutting process smoother and avoid the plastic film being stuck on the cutting knife, causing the plastic film to stick together and affecting the subsequent covering work.

[0022] 4. At the same time, when the first clamp leaves the surface of the hose, the adjusting rod can be rotated to adjust the amount of water passing through the delivery pipe to prevent excessive water from reaching the liquid inlet plate and flowing out from the small holes of the liquid inlet plate. The rotation of the adjusting rod can also open an air channel to replenish air inside the water tank to maintain the pressure balance inside the water tank, so that the water inside the water tank can flow out normally.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0035] See also Figures 1 to 9 , which is the first embodiment of the present invention, provides a technical solution: a concrete curing device for construction, comprising a base 1 and a placement bin 2 arranged on the base 1, the placement bin 2 has enough space inside for placing the plastic film 5 required for curing the concrete, an L-shaped support plate 3 is movably arranged on the placement bin 2, one of the support plates of the L-shaped support plate 3 is used to seal the opening of the placement bin 2, when the plastic film 5 needs to be taken out, the L-shaped support plate 3 will rotate, and the rotated L-shaped support plate 3 will drive the plastic film 5 arranged thereon to be exposed from the inside of the placement bin 2, so that the staff can take the plastic film 5 conveniently, and the other support plate is U-shaped, used to To avoid contact between the L-shaped support plate 3 and the water tank 6 when rotating, a placement component 4 is symmetrically arranged on the L-shaped support plate 3, and the placement component 4 is used to place materials. A plastic film 5 is arranged on the placement component 4, and the plastic film 5 is stored in the placement bin 2. Under the action of the placement plate 42 arranged on the baffle 41, the plastic film 5 is supported, so that the plastic film 5 will not easily roll from the inside of the placement bin 2 to the outside of the placement bin 2 after being placed. A water tank 6 is arranged on the placement bin 2, and a water filling port is arranged on the water tank 6 for adding required water. A part of the water tank 6 is placed inside the placement bin 2 to facilitate cooperation with the conveying component 7 to convey the water stored in the water tank 6;

[0036] The placement component 4 includes a baffle 41 symmetrically arranged on the L-shaped support plate 3, the baffle 41 is used to provide sufficient support, and a placement plate 42 arranged on one side of the baffle 41, the placement plate 42 is an L-shape, and one section of it has an inclined angle. When the plastic film 5 enters its interior through the open end of the placement plate 42 to form a sliding engagement, the placement plate 42 can support the plastic film 5. When the L-shaped support plate 3 rotates, the two placement plates 42 arranged follow the L-shaped support plate 3 to rotate, and a section with an inclined angle can make the plastic film 5 roll under the action of its own gravity, so that the plastic film 5 can completely move a distance to the outside of the placement bin 2, which is convenient for the staff to take it. The rotating plate 43 movably arranged on the placement plate 42, the rotating plate 43 is arranged at the corner of the placement plate 42, and the rotating plate 43 can have a certain blocking effect on the movement of the plastic film 5. When the plastic film 5 is stored in the placement bin 2, as the base 1 moves as a whole, the plastic film 5 will inevitably move. At this moment, the rotating plate 43 can block the movement The plastic film 5 is intercepted to a certain extent, and a moving seat 44 is movably arranged at one end of the rotating plate 43 away from the placement plate 42, and the moving seat 44 is plugged and movably connected with the placement plate 42, and the moving seat 44 is hinged with the rotating plate 43, so that when the plastic film 5 moves after the L-shaped support plate 3 rotates, the moving seat 44 can be driven to move by the hinge of the two to make the placement plate 42 have enough space inside so that the plastic film 5 can be moved to a predetermined position, and a bonding plate 45 is also arranged on the moving seat 44, and the bonding plate 4 5 is inside the placement plate 42, the laminating plate 45 is used to prevent the movable seat 44 from falling back to the initial position by continuing to squeeze the laminating plate 45 through the storage rollers on the plastic film 5 when the plastic film 5 is out of contact with the rotating plate 43 and the movable seat 44, and the fixing plate 46 is arranged on the movable seat 44, and the fixing plate 46 is used to fix the first clamping plate 461 and the movable seat 44. When the movable seat 44 is displaced, the first clamping plate 461 will release the squeezing force on the hose 72, so that water can pass smoothly.

[0037] The rotating plate 43 is symmetrically provided with a plug-in rod 431, and the plug-in rod 431 is plugged into the inside of the placement plate 42. The plug-in rod 431 is connected to the rotating plate 43 through a protrusion. There is a rotational relationship between the rotating plate 43 and the protrusion. When the rotating plate 43 is displaced, the plug-in rod 431 can follow and extend from the inside of the placement plate 42, so that the rotating plate 43 can move along a straight line during the rotation process to prevent the rotating plate 43 from being unable to rotate. The fixed plate 46 is provided with a first clamping plate 461 at one end away from the moving seat 44. The first clamping plate 461 is used to squeeze and release the hose 72 to facilitate the smooth flow of water in the hose 72. An opening and closing plate 421 is provided, and the opening and closing plate 421 is hinged with the placement plate 42. At the same time, under the action of the top block located at the bottom of the opening and closing plate 421 on the placement plate 42, the opening and closing plate 421 can only rotate in one direction. At the same time, a torsion spring is provided at the hinge between the opening and closing plate 421 and the placement plate 42, so that the opening and closing plate 421 can be in a horizontal state with the opening of the placement plate 42 in the absence of external force. At the same time, a groove is provided on the placement plate 42 to facilitate the rotation of the opening and closing plate 421. A second clamping plate 422 is provided on the side of the placement plate 42 close to the fixed plate 46. The second clamping plate 422 is used to cooperate with the first clamping plate 461. Under the action of the two, the hose 72 can be squeezed.

[0038] A square rod 21 is symmetrically arranged on the placement bin 2, and a locking buckle 22 is movably arranged on the square rod 21. The locking buckle 22 is used to lock the L-shaped support plate 3 on the placement bin 2 after the entire device is used to prevent the L-shaped support plate 3 from rotating by itself due to shaking. A handle 32 is arranged on the L-shaped support plate 3, and the handle 32 is used to facilitate the staff to smoothly pull the L-shaped support plate 3 to make it rotate.

[0039] A conveying assembly 7 is symmetrically arranged on the water tank 6, and the conveying assembly 7 is used to convey the water in the water tank 6 to wet one side of the plastic film 5. A positioning plate 31 is arranged on the L-shaped support plate 3, and the positioning plate 31 is used for the plastic film 5 to pass through the gap in the middle. The plastic film 5 is clamped by the cooperation between the liquid inlet plate 74 and the positioning plate 31. A cutting assembly 8 is arranged on the positioning plate 31, and the cutting assembly 8 is used to cut the plastic film 5.

[0040] During use, the device is first moved to the concrete to be cured, and then the locking buckle 22 on the placement bin 2 is removed from the L-shaped support plate 3 to unlock it, and then the L-shaped support plate 3 is rotated by pulling the handle 32. When the L-shaped support plate 3 rotates, the plastic film 5 clamped on the placement plate 42 will slide along the placement plate 42, and the sliding plastic film 5 will first contact the rotating plate 43, so that the rotating plate 43 drives the moving seat 44 to be lifted during the rotation. When the plastic film 5 leaves the rotating plate 43 and contacts the bonding plate 45, the moving seat 44 fixedly connected to the bonding plate 45 will The current height will be maintained without falling back, and the raised movable seat 44 will drive the first clamping plate 461 to release the squeezing effect on the conveying component 7, so that the water in the water tank 6 can smoothly pass through the conveying component 7 to the bottom side of the plastic film 5, and then the water will be adhered to the bottom side of the plastic film 5 by pulling out the plastic film 5. When the plastic film 5 covers the concrete surface, it can carry some water to provide moisturizing effect, thereby increasing its maintenance effect. After pulling out the required size, the plastic film 5 is cut by the cutting component 8, so that the staff can move the device to the next position to perform the above operations. Example 2

[0041] See also Figures 1 to 9 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0042] The delivery assembly 7 includes a delivery pipe 71 symmetrically arranged on the water tank 6. A section of the delivery pipe 71 is a corrugated pipe, which is used to provide a sufficient length so that the delivery pipe 71 can extend the delivery channel when in use. A hose 72 is arranged at the end of the delivery pipe 71 away from the water tank 6. The hose 72 is used to cooperate with the first clamping plate 461 and the second clamping plate 422. Under the action of the two clamping plates, the hose 72 is squeezed and released, which is convenient for adjusting the water flow inside the hose 72. A liquid inlet pipe 73 is arranged at the end of the hose 72 away from the delivery pipe 71. The liquid inlet pipe 73 is used to guide the water so that the water can flow smoothly. It flows into the liquid inlet plate 74 and then adheres to the plastic film 5, so as to provide a moist environment when the plastic film 5 is covered on the concrete. A section of bellows is also provided in the liquid inlet pipe 73 to meet the movement of the lower section of the liquid inlet pipe 73. The liquid inlet plate 74 is provided at the end of the liquid inlet pipe 73 away from the hose 72, and the liquid inlet plate 74 is located directly below the positioning plate 31. The interior of the liquid inlet plate 74 is a cavity, and a plurality of small holes are arranged in an array on the liquid inlet plate 74, so as to facilitate the water to adhere to the opening through the tension of the water itself when filling the interior of the liquid inlet plate 74, and to adhere the water to the surface of the plastic film 5 under the contact of the plastic film 5.

[0043] A telescopic rod 741 is arranged in an array on one side of the liquid inlet plate 74 close to the L-shaped support plate 3. The telescopic rod 741 is used to support the liquid inlet plate 74 to prevent the liquid inlet plate 74 from shaking when moving. A first spring 742 is sleeved on the outside of the telescopic rod 74. The first spring 742 is used to provide sufficient elastic force for the liquid inlet plate 74 so that the liquid inlet plate 74 can cooperate with the positioning plate 31 to clamp the plastic film 5 to prevent it from loosening so that the plastic film 5 needs to be repositioned and pulled out when it is used next time. An adjustment component 9 is arranged on the delivery pipe 71 to adjust the outflow of water.

[0044] The cutting assembly 8 includes a sliding rod 81 arranged on the positioning plate 31, and the sliding rod 81 is used to move and limit the cutting knife 82. After the staff takes out enough plastic film 5, the plastic film 5 is cut by moving the cutting knife 82. The cutting knife 82 is movably arranged on the sliding rod 81, and the cutting knife 82 is in a V shape. While conveniently providing positioning and squeezing for the plastic film 5, the plastic film 5 is cut by the movable shearing effect between the inner cutting knife 83 and the cutting knife 82. The inner cutting knife 83 is movably arranged on the cutting knife 82. The inner cutting knife 83 cooperates with the notch on the cutting knife 82 through the top block provided, so that the inner cutting knife 83 can move along the notch on the cutting knife 82 when moving. The direction is shifted to make the whole shearing effect better. A limit plate 84 is arranged on the side of the positioning plate 31 close to the cutting knife 82. A notch is opened on the limit plate 84 to support the bottom of the cutting knife 82, so as to provide sufficient support force for the cutting knife 82, so that the cutting knife 82 is more stable when moving. The corrugated guide rail 85 arranged on the limit plate 84 can drive the inner cutting knife 83 to move synchronously through the movable plate 852 through the corrugated groove opened therein when the cutting knife 82 moves. When the limit rod 851 arranged on the movable plate 852 performs synchronous corrugated lifting and lowering with the corrugated groove, the inner cutting knife 83 can be pushed to move inside the cutting knife 82, thereby cutting the plastic film 5.

[0045] A limit rod 851 is movably provided on the corrugated guide rail 85, and a movable plate 852 is provided at one end of the limit rod 851. A notch is provided on the movable plate 852 for engaging and sliding with the top rod on the cutting knife 82, so that the movable plate 852 is displaced under the drive of the cutting knife 82. A slide groove 831 is provided on the inner cutting knife 83, and the movable plate 852 engages and slides with the slide groove 831. Under the action of the slide groove 831 on the inner cutting knife 83 and the movable plate 852, the waveform lifting transmitted by the corrugated guide rail 85 is converted into thrust, which pushes the inner cutting knife 83 to move on the cutting knife 82. A push button 821 is provided on the cutting knife 82, and the push button 821 is used to facilitate the staff to push the cutting knife 82 to move.

[0046] During use, when the plastic film 5 is moved along the placement plate 42, the water in the water tank 6 will reduce the amount of water passing through the delivery pipe 71 through the adjustment component 9, and then reach the hose 72. At this moment, the first clamping plate 461 on the hose 72 will leave the surface of the hose 72 under the movement of the moving seat 44, so that the hose 72 is no longer clamped by the first clamping plate 461 and the second clamping plate 422, so that the water can smoothly reach the liquid inlet plate 74. When there is enough water stored in the liquid inlet plate 74, the excess water will emerge through the small holes on the liquid inlet plate 74, and the small holes on the liquid inlet plate 74 are located on one side of the liquid inlet plate 74 and at the arc angle. Therefore, when water adheres to the plastic film 5, When the staff pulls, the adhered water will not be scraped off again due to the horizontal surface of the liquid inlet plate 74 itself. Under the action of the water's own tension and the amount of water, the water can stay on the surface of the liquid inlet plate 74 for a short time, which is convenient for the plastic film 5 to carry the water. When enough plastic film 5 is taken out to completely cover the concrete, the cutting knife 82 is moved by moving the push button 821. The moving cutting knife 82 will drive the moving plate 852 to move synchronously. The movement of the moving plate 852 converts the waveform lifting and lowering transmitted on the waveform guide rail 85 into a thrust for the inner cutting knife 83, so that the inner cutting knife 83 can form a shear with the cutting knife 82, thereby completing the shearing of the plastic film 5.

[0047] The remaining structures are the same as those of Example 1. Example 3

[0048] See also Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0049] The adjustment assembly 9 includes a branch pipe 91 arranged on the delivery pipe 71, an adjustment rod 92 movably arranged inside the branch pipe 91, the adjustment rod 92 is located inside the delivery pipe 71 and is in a spherical shape, and the outer diameter contour of the spherical shape fits the inner wall of the delivery pipe 71, and the adjustment rod 92 has a cavity inside that directly passes through the interior of the delivery pipe 71, and a circular through hole is also provided at the spherical shape of the adjustment rod 92, which is used to close the flow channel inside the delivery pipe 71 when the adjustment rod 92 rotates, so that it can form a smaller flow channel, reduce the flow rate of water, and avoid too fast water outflow at the liquid inlet plate 74, and a matching rod 93 is set at the end of the adjustment rod 92 away from the delivery pipe 71, and the matching rod 93 is used to cooperate with the oblique push plate 96, and can push the matching rod 9 when the oblique push plate 96 moves. 3 is rotated, so that the adjusting rod 92 fixedly connected to the matching rod 93 is rotated synchronously, thereby reducing the outflow of water in the delivery pipe 71, the fixed support rod 94 arranged on one side of the branch pipe 91, the sliding rod 95 movably arranged on the fixed support rod 94, and the oblique push plate 96 arranged on the end of the sliding rod 95 away from the fixed support rod 94, the oblique push plate 96 has a certain inclination, and one side is also inclined, which is used to cooperate with the first clamping plate 461. Under the movement of the first clamping plate 461, the oblique surface of the oblique push plate 96 can be squeezed to make it move. When the matching rod 93 contacts it, it will push the matching rod 93 to rotate, so as to complete the reduction of the water flow rate. The maximum moving distance of the first clamping plate 461 will not cause the first clamping plate 461 to completely break away from the contact with the oblique push plate 96.

[0050] A second spring 951 is sleeved on the slide bar 95, and one end of the second spring 951 is in contact with the oblique push plate 96. The second spring 951 is used to reset the oblique push plate 96 under the action of the second spring 951 after the oblique push plate 96 is no longer squeezed by the first clamping plate 461. An array of air holes 911 are provided on the branch pipe 91. The air holes 911 are used to send outside air into the water tank 6 when the air channel is opened after the adjustment rod 92 is rotated, so that the water tank 6 can maintain pressure balance and allow water to flow out of the delivery pipe 71 smoothly.

[0051] During use, when the water inside the water tank 6 is transported, the rotation of the adjusting rod 92 arranged on the branch pipe 91 on the delivery pipe 71 will be able to reduce the amount of water reaching the hose 72. At the same time, the rotation of the adjusting rod 92 is achieved by moving the first clamping plate 461 to push the oblique push plate 96 to contact the matching rod 93, so that the adjusting rod 92 rotates, and the air channel opened on the adjusting rod 92 and the vent hole 911 on the branch pipe 91 form a complete air circulation channel. Then, the outside air can enter the water tank 6 through this air channel, so that the pressure inside the water tank 6 remains balanced, so that water can flow out smoothly to wet the plastic film 5.

[0052] The remaining structures are the same as those of embodiments 1 and 2.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
