Description

Technical Field

[0001] This application relates to the field of construction engineering, and in particular to a concrete curing device for construction engineering. Background Art

[0002] Concrete curing refers to taking a series of measures to keep the concrete moist and at an appropriate temperature after the concrete is poured, so as to ensure the strength and durability of the concrete, and to promote the hydration reaction and hardening process of the concrete. Specifically, after manually sprinkling water on the concrete floor, the concrete is covered with a plastic film as soon as possible. However, both sprinkling water and laying the film require time, and the time difference between the two will cause some water loss. Therefore, how to reduce the time difference between sprinkling water and laying the film is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0003] In order to reduce the time difference between sprinkling water and laying the film and better carry out water retention curing on the concrete, this application provides a concrete curing device for construction engineering.

[0004] A concrete curing device for construction engineering provided by this application adopts the following technical solutions: A concrete curing device for construction engineering includes a main bracket, walking wheel sets arranged on both sides of the main bracket, a feeding component connected to the lower end of the main bracket for connecting a film roll, and a water sprinkling component arranged on the main bracket. The water sprinkling component is located between the walking wheel sets and the feeding component. The main bracket includes two symmetrically arranged side brackets and a push rod for connecting the two side brackets. The feeding component is located between the two side brackets. The walking wheel sets are installed on the side brackets. A support member for jacking the main bracket off the ground and a first driving member for driving the support member to approach or leave the main bracket are provided at the lower end of the main bracket. The support member is rotatably connected to the first driving member. There are two support members and they are distributed on the two side brackets respectively; when the main bracket rotates around one of the support members, the left and right end directions of the feeding component are exchanged.

[0005] By adopting the above technical solutions, the operator stands on the side of the walking wheel sets away from the water sprinkling component. First, fix one end of the film roll at one end of the concrete to be cured, and then push the main bracket to walk. After the water sprinkling component sprinkles water, the feeding component unwinds the film roll. When one column of the film roll is laid, at this time the main bracket has moved to the wall, and the main bracket can be jacked off the ground through the support member, and the main bracket is rotated with the support member as the base point, so that the left and right end directions of the feeding component are exchanged. Then the main bracket can continue to walk to lay another column. After repeating many times, a whole piece of film can be laid on the concrete floor. And in this process, the film is directly laid after the water sprinkling is completed, reducing the time difference between sprinkling water and laying the film, and better carrying out water retention curing on the concrete.

[0006] Optionally, the side bracket includes a main frame body, a loading frame body and a walking frame body. The loading frame and the walking frame body are located in the same plane. The loading assembly is installed between two loading frame bodies, and one walking assembly corresponds to one walking frame body and is located on the inner side of the walking frame body facing inward.

[0007] By adopting the above technical solution, when laying the outermost column of the concrete floor, the distance between the film roll on the loading assembly and the side wall of the concrete is reduced, and the film is laid on the concrete floor as evenly as possible.

[0008] Optionally, there are two loading assemblies, and one side bracket corresponds to one loading assembly. The loading assembly includes a mounting seat rotatably connected to the main frame body, clamping pieces slidably connected to the mounting seat, and adjusting pieces. There are two clamping pieces and they are symmetrically arranged. The adjusting piece is used to drive the two clamping pieces to approach or move away from each other. The clamping pieces are arc-shaped.

[0009] By adopting the above technical solution, the film roll can be fixed by the outer top of the inner wall of the film roll by the clamping pieces, or the film roll can be fixed by directly clamping one end of the innermost side of the film roll by the two clamping pieces. When it is necessary to lift the film roll for secondary glue curing, one end of the film can be clamped by the clamping pieces, and then the film can be wound around the clamping pieces for winding, so as to realize the reuse of the film.

[0010] Optionally, the walking wheel set includes two walking wheels. When the two walking wheels contact the walking surface, there is a gap between the film roll on the loading assembly and the walking surface.

[0011] By adopting the above technical solution, the film roll will not be interfered by the concrete surface during unwinding, and at the same time, the contact area between the film and the concrete surface is reduced as much as possible, reducing the influence of the film on the flatness of the concrete surface and the resistance generated by the concrete surface on the film when the film is peeled off later.

[0012] Optionally, the walking frame body is positioned and rotatably connected to the main frame body. When the walking frame body rotates relative to the main frame body, the distance between the film roll on the loading assembly and the walking surface changes.

[0013] By adopting the above technical solution, the distance between the walking frame and the main frame body can be adjusted according to requirements, so as to ensure that there is a gap between the film roll on the loading assembly and the walking surface during film laying. When the curing device is not in use, the walking wheels can also be adjusted to be flush with the film roll, so that the curing device can be placed more stably.

[0014] Optionally, the walking frame body includes a first walking rod and a second walking rod. The two walking wheels are respectively rotatably connected to the first walking rod and the second walking rod. One end of the first walking rod is positioned and rotatably connected to the main frame body, and the second walking rod is fixedly connected to the first walking rod and is telescopically arranged.

[0015] By adopting the above technical solution, it is ensured that the two walking wheels can be adjusted to contact the ground simultaneously, ensuring the stable walking of the maintenance device.

[0016] Optionally, a linkage assembly is provided between the walking wheel set and the feeding assembly on the same side bracket, and the linkage assembly is used to drive the mounting seat to rotate as one of the walking wheels rotates.

[0017] By adopting the above technical solution, the film roll can rotate by itself, facilitating the discharging and laying of the film.

[0018] Optionally, a blanking assembly is installed on the main bracket, and the blanking assembly is used to feed the pressing rod parallel to the film roll, and the blanking assembly is located on the side of the feeding assembly away from the walking wheel set.

[0019] By adopting the above technical solution, a fixed pressure can be applied to the already laid film, ensuring that the film can be laid more stably on the concrete surface.

[0020] Optionally, the blanking assembly includes a rod storage box with openings at both ends, a first baffle slidably connected to the lower end of the rod storage box, a second baffle slidably connected to the middle of the rod storage box, and a second driving assembly for driving the first baffle and the second baffle to move; when the first baffle blocks the lowermost pressing rod from leaving the rod storage box, the second baffle does not block all the pressing rods; when the first baffle does not block the opening at the lower end of the rod storage box, the second baffle blocks the pressing rod at the second lowest position.

[0021] By adopting the above technical solution, when it is necessary to lower the pressing rod, first make the second baffle block the pressing rod at the second lowest position, and then open the first baffle so that the pressing rod leaves the rod storage box and presses on the film, which is convenient to operate. After the pressing rod drops, the first baffle slides to the position where it blocks the lower end of the rod storage box, and the second baffle opens so that the pressing rod above the second baffle falls onto the first baffle, preparing for the next discharging of the pressing rod.

[0022] Optionally, the second driving assembly includes a first rack fixedly connected to the first baffle, a second rack fixedly connected to the second baffle, a linkage gear rotatably connected to the rod storage box, and a second driving member for driving the linkage gear to rotate, and the lower part of the linkage gear meshes with the first rack and the upper part meshes with the second rack.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. After watering the concrete, directly lay the film, reducing the time difference between watering and laying the film, and better performing water conservation maintenance on the concrete; 2. The manual labor intensity is small, and only by pushing the maintenance device can watering and film laying be completed; 3. The film can be recycled, and the operation is convenient.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0038] An embodiment of the present application discloses a concrete curing device for construction engineering.

[0039] Please refer to Figure 1In one embodiment of the present application, a concrete curing device for construction engineering includes a main support 1, a walking wheel group 2 arranged on both sides of the main support 1, a watering assembly 3 arranged on the main support 1, a feeding assembly 4 connected to the lower end of the main support 1 for connecting a film roll 6, and a feeding assembly 5 arranged on the main support 1 for storing a pressing rod 7. The watering assembly 3 is located between the walking wheel group 2 and the feeding assembly 4. The film roll 6 is wound by a film roll 6.

[0040] The operator stands on the side of the walking wheel group 2 away from the sprinkler assembly 3, and first fixes the discharge end of the film roll 6 at one end of the concrete to be cured through the pressing rod 7, and then pushes the main support 1 to walk. After the sprinkler assembly 3 sprinkles water, the loading assembly 4 unwinds the film roll 6. When the film roll 6 has laid a row, the main support 1 has moved out of the curing area. The film roll 6 is fixed again through the unloading assembly 5 unloading pressing rod 7. Then the main support 1 is rotated to exchange the left and right ends of the loading assembly 4, and then the main support 1 can continue to walk to lay another row. After repeated multiple times, the film 61 can be laid on the concrete floor in one piece. Please refer to Figure 2 During the laying process, pressing rods 7 can be pressed on both ends of each row of films 61 to make the films 61 more stably laid on the concrete surface for water retention. In this process, the films 61 are laid directly after the watering is completed, reducing the time difference between watering and laying the films 61, and better maintaining the water retention of the concrete.

[0041] For details, please refer to Figure 1 and Figure 3 The main support 1 includes two symmetrically arranged side supports 11 and a push rod 12 for connecting the two side supports 11. The side support 11 includes a main frame body 111, a loading frame body 112 and a walking frame body 113, and the loading frame and the walking frame body 113 are located in the same plane. There are two loading components 4, and one side support 11 corresponds to one loading component 4, and the loading component 4 is located on the inner side of the side support 11. There are two walking components, and one side support 11 corresponds to one walking component, and the walking component is also located on the inner side of the side support 11.

[0042] Specifically, the walking wheel group 2 includes two walking wheels 21. When laying the film 61, the two walking wheels 21 contact the walking surface, and there is a gap between the film roll 6 on the loading assembly 4 and the walking surface. The walking surface is a curing surface for concrete to be cured and watered. As a result, when the film roll 6 is unrolled, there will not be too much friction interference between the film 61 and the walking surface, so that the film 61 can be discharged more easily and smoothly. At the same time, in conjunction with the action of laying the film 61 in the area where the walking wheel group 2 passes, the suspended film roll 6 can reduce the contact area between the film 61 and the concrete surface, thereby reducing the influence of the film 61 on the flatness of the concrete surface and the resistance of the concrete surface to the film 61 when the film 61 is subsequently peeled off.

[0043] Further, please refer to Figure 3 and Figure 4 As shown in FIGS. Figure 3 and Figure 4 , the traveling frame 113 includes a first traveling rod 1131 and a second traveling rod 1132. Two traveling wheels 21 are respectively rotatably connected to the first traveling rod 1131 and the second traveling rod 1132. One end of the first traveling rod 1131 is rotatably connected to the main frame 111 in a positioning manner, and the second traveling rod 1132 is fixedly connected to the first traveling rod 1131. The angle of the traveling frame 113 relative to the main frame 111 can be adjusted by rotating the first traveling rod 1131, so as to adjust the height of the film roll 6 relative to the ground, so that the distance between the film roll 6 and the ground meets the requirements of the user. When it is necessary to lay the film 61, the angle of the first traveling rod 1131 relative to the main frame 111 is adjusted to ensure that there is a gap between the film roll 6 and the traveling surface, so as to facilitate the laying of the film 61. When the curing device is not needed, the angle of the first traveling rod 1131 relative to the main frame 111 is adjusted until the film roll 6 and the traveling wheels 21 contact the ground at the same time, so that the curing device is placed on the ground more stably.

[0044] Specifically, a lifting lug seat 1111 is provided on the main frame 111, and one end of the first traveling rod 1131 is rotatably connected to the lifting lug seat 1111. The mounting bolt 1133 passes through the lifting lug seat 1111 and the first traveling rod 1131 and is rotatably connected to the lifting lug seat 1111 and the first traveling rod 1131. One end of the mounting bolt 1133 is threadedly connected to the mounting nut 1134. When the mounting nut 1134 is tightened, the mounting nut 1134 and the mounting bolt 1133 clamp the lifting lug seat 1111 and the first traveling rod 1131, so that the lifting lug seat 1111 and the first traveling rod 1131 are relatively fixed. When it is necessary to adjust the angle of the traveling frame 113 relative to the main frame 111, just loosen the mounting nut 1134, which is convenient to operate.

[0045] Further, the second traveling rod 1132 is telescopically arranged. If the traveling wheel 21 corresponding to the second traveling rod 1132 cannot contact the ground after the angle of the first traveling rod 1131 is adjusted, the second traveling rod 1132 can be extended at this time to ensure that the traveling wheels 21 on the second traveling rod 1132 and the traveling wheels 21 on the first traveling rod 1131 contact the ground synchronously. Specifically, the second traveling rod 1132 includes a fixed part 11321 fixedly connected to the first traveling rod 1131, a sliding part 11322 slidably sleeved on the fixed part 11321, and a locking bolt 11323 threadedly connected to the sliding part 11322. The traveling wheel 21 is rotatably connected to one end of the sliding part 11322 away from the fixed part 11321. When the locking bolt 11323 rotates to abut against the fixed part 11321, the sliding part 11322 is fixed relative to the fixed part 11321. When it is necessary to adjust the length of the traveling rod, just loosen the locking bolt 11323 and move the sliding part 11322 relative to the fixed part 11321.

[0046] Specifically, please refer to Figure 1 , the sprinkling assembly 3 includes a water supply tank 31, a water sprinkling pipe 32 that is parallel to the film roll 6 and fixedly arranged on the main frame body 111, a connecting pipe 33 for connecting the water sprinkling pipe 32 and the water supply tank 31, and a water pump for providing the power for sprinkling. The water pump is not shown in the figure. The water in the water supply tank 31 is supplied to the water sprinkling pipe 32 through the water pump to complete sprinkling. In other embodiments, the water supply pipe may not be provided, and the connecting pipe 33 is directly connected to a water faucet or other water sources for sprinkling.

[0047] Specifically, please refer to Figure 1 and Figure 5 , there are two feeding assemblies 4, and one side bracket 11 corresponds to one feeding assembly 4. The feeding assembly 4 includes a mounting seat 41 rotatably connected to the main frame body 111, a clamping piece 42 slidably connected to the mounting seat 41, and an adjusting member 43. There are two clamping pieces 42 and they are symmetrically arranged. The adjusting member 43 is used to drive the two clamping pieces 42 to approach or separate from each other, and the clamping piece 42 is arc-shaped. The film roll 6 can be fixed by the outer wall of the clamping piece 42 pressing against the inner wall of the film roll 6, or the film roll 6 can be fixed by directly clamping one end of the innermost side of the film roll 6 with the two clamping pieces 42.

[0048] Specifically, the adjusting member 43 includes an adjusting screw rod arranged along the connection direction of the two clamping pieces 42. The two ends of the adjusting screw rod are respectively threadedly connected to the two clamping pieces 42, and the thread directions connected to the two clamping pieces 42 are opposite. The adjusting screw rod is rotatably connected to the mounting seat 41 and is axially fixed relative to the mounting seat 41. By rotating the adjusting screw rod, the two clamping pieces 42 can be driven to approach or separate from each other.

[0049] Specifically, please refer to Figure 6 and Figure 7, the blanking assembly 5 includes a rod storage box 51 with open ends at both ends, a first baffle 52 slidably connected to the lower end of the rod storage box 51, a second baffle 53 slidably connected to the middle of the rod storage box 51, and a second driving assembly for driving the first baffle 52 and the second baffle 53 to move. One end of the second baffle 53 facing inward is provided with a guiding surface for guiding the second baffle 53 to be inserted between two pressing rods 7. In the non-blanking state, all the pressing rods 7 in the rod storage box 51 are supported by the first baffle 52, and the second baffle 53 does not support the pressing rods 7. When blanking is required, the second baffle 53 moves inward and is inserted between the lowest pressing rod 7 and the penultimate pressing rod 7; at the same time, the first baffle 52 moves outward to open the lower end of the rod storage box 51, so that the pressing rods 7 leave the rod storage box 51 and are placed on the film 61, making the film 61 more stably laid on the concrete surface to be cured. After the pressing rods 7 fall off, the first baffle 52 slides to a position blocking the lower end of the rod storage box 51, and the second baffle 53 moves outward to leave the pressing rods 7, so that the pressing rods 7 above the second baffle 53 fall onto the first baffle 52, preparing for the next discharge of the pressing rods 7.

[0050] Specifically, the second driving assembly includes a first rack 54 fixedly connected to the first baffle 52, a second rack 55 fixedly connected to the second baffle 53, a linkage gear 56 rotatably connected to the rod storage box 51, and a second driving member 57 for driving the linkage gear 56 to rotate. The lower part of the linkage gear 56 meshes with the first rack 54 and the upper part meshes with the second rack 55. By driving the linkage gear 56 to rotate through the second driving member 57, the first baffle 52 and the second baffle 53 can be synchronously and reversely slid.

[0051] Further, referring to Figure 1 and Figure 8 , the second driving member 57 is a transmission gear 571 rotatably connected to the upper end of the main frame body 111, a synchronous belt 572 for connecting the transmission gear 571 and the linkage gear 56, a force-applying rod 573 for driving the transmission gear 571 to rotate, and a force-applying handle 574 fixedly connected to one end of the force-applying rod 573. The force-applying rod 573 is rotatably connected to the main frame body 111. By the transmission gear 571 and the synchronous belt 572, the force-applying end to the linkage gear 56 is led to a height closer to the operator's hand on the main frame body 111, facilitating the operator to drive the linkage gear 56 to rotate. In other embodiments, the second driving member 57 can directly be a motor, and the rotation of the linkage gear 56 is achieved by controlling the rotation direction of the motor. In other embodiments, two transmission gears 571 can also be provided, one of the transmission gears 571 is coaxially rotatably connected to the linkage gear 56, and the synchronous belt 572 is used to connect the two transmission gears 571.

[0052] Further, referring to Figure 3, To facilitate the rotation of the main support 1, a support member 8 for lifting the main support 1 off the ground and a first driving member 81 for driving the support member 8 to approach or move away from the main support 1 are provided at the lower end of the main support 1. There are two support members 8, which are distributed on two side supports 11 respectively. One support member 8 corresponds to one first driving member 81 and is rotatably connected to its corresponding first driving member 81. The first driving member 81 is an electric cylinder. The support member 8 can be an element with a large frictional force when contacting the wall, such as a rubber block or a suction cup. After a row of the film 61 is laid and fixed at both ends, the first driving member 81 can be driven to make the support member 8 abut against the outer edge of the wall or the surface to be cured, so that the walking wheel set 2 is suspended, and the main support 1 is rotated with the support member 8 as the fulcrum, thus completing the direction exchange of the left and right ends of the feeding assembly 4.

[0053] Further, after the direction of the left and right ends of the feeding assembly 4 is exchanged, a part of the feeding assembly 4 overlaps with the row of the film 61 that has been laid, so as to better ensure that the concrete plane to be cured is protected by the film 61 as much as possible.

[0054] Embodiment 2 The difference between Embodiment 2 and Embodiment 1 is that, referring to Figure 9 , A linkage assembly 9 is provided between the walking wheel set 2 and the feeding assembly 4 on the same side support 11. The linkage assembly 9 is used to drive the mounting seat 41 to rotate as one of the walking wheels 21 rotates. The linkage assembly 9 includes a first linkage wheel 91 fixedly connected to the rotating shaft of one of the walking wheels 21, a second linkage wheel 92 fixedly connected to the rotating shaft of the mounting seat 41, and a linkage belt 93 synchronously sleeved on the first linkage wheel 91 and the second linkage wheel 92. The linkage belt 93 is tensioned by the first linkage wheel 91 and the second linkage wheel 92.

[0055] When the main frame 111 walks, the walking wheel 21 rotates, so that the feeding assembly 4 can be driven to rotate, making the film 61 discharge more smoothly and be laid on the concrete surface to be cured. At the same time, if it is necessary to lift the film roll 6 for secondary glue curing, the pressing rod 7 is retracted, one end of the film 61 is clamped by the clamping piece 42, and then the main frame 111 is pushed. As the walking wheel 21 rotates in the reverse direction, the feeding assembly 4 is driven to rotate in the reverse direction, so that the film 61 is wound around the clamping piece 42 for winding, thus realizing the reuse of the film 61.

[0056] Embodiment 3 The difference between Embodiment 3 and Embodiment 1 is that, referring to Figure 10, further comprising a film scribing assembly 10. A sliding lead screw 101 is arranged on the main frame body 111 in a direction parallel to the film roll 6. A scribing knife 102 is fixedly connected to the slider of the sliding lead screw. The sliding direction of the scribing knife 102 relative to the main frame body 111 is the same as the direction of the film roll 6. The scribing knife 102 is used to scribe and cut the film 61. When it is necessary to scribe and cut the film 61, only need to tighten the film 61 to make it close to the scribing knife 102, and then slide the scribing knife 102, which is convenient to operate.

[0057] Furthermore, the scribing knife 102 is mounted on the slider of the sliding lead screw 101 along a direction perpendicular to the sliding lead screw 101 through a third driving member 103. The third driving member 103 is an electric cylinder or a hydraulic cylinder, etc. When it is necessary to cut the film 61, directly drive the scribing knife 102 to the area where the film 61 has left the film roll 6 and is tensioned through the third driving member 103, and then slide the scribing knife 102 to complete the cutting.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
