Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete cover plate flipping technology, and in particular to a tool for quickly flipping concrete cover plates. Background Technology
[0002] Concrete drainage ditch covers are cement products used in drainage systems. They are mainly used to protect and decorate drainage systems and are commonly used in the construction industry to cover channels or trenches to prevent people, vehicles or other objects from falling in, while ensuring the smooth operation of the drainage system.
[0003] The process of precast concrete drainage ditch covers using molds mainly includes the following steps: 1. Concrete preparation: This involves adding gravel, sand, and cement to a mixer and mixing evenly. Then, an appropriate amount of water is added and mixing continues until the concrete reaches the desired consistency. 2. Mold lubrication and assembly: Before pouring the concrete, the mold needs to be lubricated, usually using a release agent or machine oil to ensure easy demolding after pouring. Mold assembly and fixing are also part of this step, using bolts and electric wrenches to ensure stability and sealing. 3. Concrete pouring: The prepared concrete is poured into the lubricated mold. Pouring should begin from the center of the mold to avoid uneven grouting. 4. Vibration and air removal: After pouring the concrete into the mold, a vibrator is used to vibrate and remove air bubbles, ensuring uniform distribution and density. 5. Hardening and demolding: The concrete is left in the mold for a period of time to harden. After hardening, the mold can be removed to obtain the precast concrete drainage ditch cover. When removing the formwork for concrete drainage ditch covers, the concrete covers need to be demolded from the mold without damaging it. On construction sites, the traditional method is to manually turn the mold over and then remove it from the concrete covers for demolding. However, since each concrete cover weighs 115kg, at least three people are needed to turn it over. Moreover, turning it over by hand is time-consuming and laborious. Manual turning and demolding is inefficient and cannot complete the project on time.
[0004] Therefore, the existing manual method of turning molds over has the problem of slow demolding speed, resulting in low work efficiency. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a concrete cover plate quick flipping tool, which uses a sliding device and a flipping device to work together to remove the concrete cover plate from the mold.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0007] A quick-turning tool for concrete cover plates is provided for removing concrete cover plates from a mold by turning them over. It includes a sliding device and a turning device. The sliding device is positioned above the turning device and is movably connected to it. The sliding device contacts the top surfaces of both sides of the mold, and the turning device contacts the bottom surfaces of both sides of the mold. The mold is located between the sliding device and the turning device. The sliding device and the turning device are used to define the position of the mold by interlocking. The turning device is used to form a fulcrum with the ground for turning the concrete cover plate.
[0008] Compared with the prior art, the present invention has the following advantages:
[0009] After sliding on the tilting device, the sliding device comes into contact with the mold, positioning the mold between the two. The top surface of the mold contacts the sliding device, and the bottom surface contacts the tilting device. When the sliding device engages with the tilting device, the mold is completely clamped between the two devices. The bottom of the tilting device forms a pivot point with the ground, allowing it to be tilted. By operating the tilting device to rotate around this pivot point, it can be tilted, thus flipping the mold upside down onto the ground. This completely separates the concrete cover from the mold, completing the demolding process. This method replaces manual tilting of the concrete cover, easily completing the demolding work, improving work efficiency, and reducing the workload of workers.
[0010] More preferably, the sliding device includes:
[0011] The demolding frame is positioned above the flipping device and is slidably connected to the flipping device.
[0012] A sliding component is mounted on the flipping device, with one end fixedly connected to the demolding frame and the other end inserted into the flipping device for sliding.
[0013] Using the above technical solution, the demolding frame drives the sliding component to reciprocate on the flipping device to complete the action of clamping and releasing the mold, which has the characteristics of saving time and effort and quickly clamping the mold.
[0014] More preferably, the sliding component includes:
[0015] The sliding column is located inside the tilting device and contacts the interior of the tilting device, and is used to move within the tilting device.
[0016] The connecting shaft runs through the slide column and is rotatably connected to the slide column, with its end located on the outside of the slide column.
[0017] The slide bar is mounted on the connecting shaft. One end of the slide bar is fixedly connected to the end of the connecting shaft, and the other end is fixedly connected to the demolding frame. It is used to drive the slide bar to move along with the demolding frame.
[0018] Using the above technical solution, the demolding frame is pushed toward or away from the mold, the demolding frame drives the slide rod to move, and the slide rod drives the connecting shaft to move, so that the slide column moves on the flipping device, thereby completing the process of clamping or releasing the mold.
[0019] More preferably, the flipping device includes:
[0020] The support rod is located below the demolding frame and is slidably connected to the sliding column.
[0021] The flipping component is mounted on the support rod, located near the side wall of the mold. Its top is fixedly connected to the support rod, and its bottom contacts the ground, forming a fulcrum with the ground.
[0022] Using the above technical solution, the support rod is used to provide a track for the sliding column, so that the demolding frame can move accurately to the top surface of the mold and form a relative sliding motion mode with the mold.
[0023] Further optimization involves the following features on the support poles:
[0024] The track is formed on the surface of the support rod and extends from the end of the support rod away from the mold to a position near the middle of the mold, where it contacts the sliding column.
[0025] The stop block is set inside the track, located on the support rod near the middle of the mold, and is integrally connected to the support rod. There is a distance between it and the bottom surface and inner wall of the track, and it forms a cavity with the track for engaging the sliding column.
[0026] Using the above technical solution, the sliding column can move smoothly on the track. When the sliding column enters the cavity between the stop and the track, the sliding rod also enters between the stop and the inner wall of the track, thus completing the sliding component being inserted into the frame rod. In order to flip the mold, the mold is limited between the demolding frame and the frame rod in advance.
[0027] Further optimizations include the following flip component:
[0028] The support legs are set on the bottom surface of the support rod, near the mold, and their tops are fixedly connected to the support rod.
[0029] The outriggers are flipped up and bent, located at the bottom of the outriggers. The top of the outriggers is integrated with the outriggers, and the bottom contacts the ground.
[0030] The rollers are located inside the tilting feet, on the inner side of the tilting feet, rotatably connected to the tilting feet, and in contact with the ground.
[0031] Using the above technical solution, when lifting the support rod, first step on the fulcrum where the flipping support foot contacts the ground with your toes, causing the support rod to rotate around the fulcrum. Then, the support rod can be easily flipped, achieving a smooth flipping and quick demolding process. Before flipping, press down and then push the support rod to move the rollers, thereby pushing the tool to the vicinity of the mold, saving time and effort.
[0032] Further optimization involves flipping the outriggers to form a hook shape with the legs.
[0033] Using the above technical solution, when the frame pole is pressed down and pushed, the flip-out foot can easily rotate relative to the ground, and the roller can easily roll on the ground.
[0034] Further optimization involves making the sides of the flip-up support legs ∠-shaped.
[0035] Using the above technical solution, during the flipping process, the toes can easily step on the tip of the flipping support foot, making the flipping support foot a fulcrum with the ground, and causing the frame pole to naturally tilt up, thus achieving the purpose of easily flipping the frame pole and inverting the mold.
[0036] Further optimization involves having four sets of sliding components, located in the middle of the demolding frame and near the flipping component.
[0037] Using the above technical solution, the sliding component located in the middle of the demolding frame can be engaged with the support rod through the stop block, thereby limiting the position of the demolding frame on the support rod and achieving the purpose of clamping the mold with the support rod.
[0038] Further optimization involves bending the support poles, with the included angle of the bent portion ranging from 120° to 150°.
[0039] By adopting the above technical solution, when the bent frame pole within this angle range is flipped, the hand can exert less force, which has the characteristic of saving effort. Attached Figure Description

Detailed Implementation
[0049] The following is in conjunction with the appendix Figures 1-8 This utility model will be described in further detail.
[0050] A quick flipping tool for concrete cover plates, such as Figure 1 As shown, a device for removing a concrete cover plate 4 from a mold 3 by flipping includes a sliding device 1 and a flipping device 2. The sliding device 1 is positioned above the flipping device 2 and is movably connected to the flipping device 2. The sliding device 1 contacts the top surfaces of both sides of the mold 3, and the flipping device 2 contacts the bottom surfaces of both sides of the mold 3. The mold 3 is located between the sliding device 1 and the flipping device 2. The sliding device 1 and the flipping device 2 are used to limit the position of the mold 3 by interlocking. The flipping device 2 is used to form a fulcrum with the ground for flipping the concrete cover plate 4.
[0051] After sliding on the flipping device 2, the sliding device 1 contacts the mold 3, placing the mold 3 between them. The top surface of the mold 3 contacts the sliding device 1, and the bottom surface contacts the flipping device 2. When the sliding device 1 is engaged with the flipping device 2, the mold 3 is completely clamped between the sliding device 1 and the flipping device 2. The bottom of the flipping device 2 forms a fulcrum that can be flipped over with the ground. By operating the flipping device 2 to rotate around the fulcrum, it can flip itself over, thereby turning the mold 3 upside down on the ground, so that the concrete cover 4 is completely separated from the mold 3 and detached. This completes the flipping of the concrete cover 4, replacing manual flipping of the concrete cover 4 and easily completing the demolding work, which can improve work efficiency and reduce the labor intensity of workers.
[0052] Specifically, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the sliding device 1 in this embodiment includes:
[0053] The demolding frame 11 is positioned above the flipping device 2 and is slidably connected to the flipping device 2.
[0054] The sliding component 12 is disposed on the flipping device 2, one end of which is fixedly connected to the demolding frame 11, and the other end is inserted into the flipping device 2 for sliding.
[0055] The demolding frame 11 drives the sliding component 12 to reciprocate on the flipping device 2, completing the action of clamping and releasing the mold 3, which has the characteristics of saving time and effort and quickly clamping the mold 3.
[0056] Specifically, such as Figure 1 and Figure 6 As shown, the sliding component 12 in this embodiment includes:
[0057] The sliding column 121 is disposed inside the flipping device 2 and contacts the interior of the flipping device 2 for movement within the flipping device 2.
[0058] The connecting shaft 122 passes through the slide column 121 and is rotatably connected to the slide column 121, with its end located on the outside of the slide column 121.
[0059] The slide bar 123 is mounted on the connecting shaft 122. One end of the slide bar 123 is fixedly connected to the end of the connecting shaft 122, and the other end is fixedly connected to the demolding frame 11. It is used to drive the slide column 121 to move along with the demolding frame 11.
[0060] The demolding frame 11 is pushed toward or away from the mold 3. The demolding frame 11 drives the slide bar 123 to move, and the slide bar 123 drives the connecting shaft 122 to move, so that the slide column 121 moves on the flipping device 2, thereby completing the process of clamping or releasing the mold 3.
[0061] Specifically, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the flipping device 2 in this embodiment includes:
[0062] The support rod 21 is located below the demolding frame 11 and is slidably connected to the slide column 121.
[0063] The flipping component 22 is mounted on the support rod 21 and located on the support rod 21 near the side wall of the mold 3. Its top is fixedly connected to the support rod 21, and its bottom is in contact with the ground, forming a fulcrum with the ground.
[0064] A support platform 23 is positioned between the demolding frame 11 and the support rod 21. Its top surface is slidably connected to the demolding frame 11, its bottom surface is fixedly connected to the surface of the support rod 21, and its surface is slidably connected to the bottom surfaces of both sides of the mold 3. It is used to clamp the mold 3 together with the demolding frame 11. Specifically, as shown... Figure 8 As shown, the support frame 23 is L-shaped, which can prevent the mold 3 from swaying between the demolding frame 11 and the support rod 21.
[0065] The support rod 21 provides a track 211 for the sliding column 121, enabling the demolding frame 11 to move accurately to the top surface of the mold 3 and form a relative sliding motion mode with the mold 3. Moreover, before flipping the mold 3, the position of the mold 3 is temporarily limited by the support platform 23, the sliding component 12 and the support rod 21, which serves as a clamping function and prepares for the flipping component 22 to flip the mold 3.
[0066] Specifically, such as Figure 5 , Figure 6 as well as Figure 7 As shown, in this embodiment, the support pole 21 is respectively provided with:
[0067] The track 211 is formed on the surface of the support rod 21 and extends from the end of the support rod 21 away from the mold 3 to a position near the middle of the mold 3, and contacts the slide column 121.
[0068] The stop block 212 is set inside the track 211, located on the support rod 21 near the middle of the mold 3, and is integrally connected with the support rod 21. There is a distance between it and the bottom surface and inner wall of the track 211, and it forms a cavity with the track 211 for engaging the sliding column 121.
[0069] The sliding column 121 can move smoothly on the track 211. When the sliding column 121 enters the cavity between the stop block 212 and the track 211, the sliding rod 123 also enters between the stop block 212 and the inner wall of the track 211, thus completing the sliding component 12 being inserted into the support rod 21. In order to flip the mold 3, it is limited between the demolding frame 11 and the support rod 21 in advance.
[0070] Specifically, such as Figure 2 and Figure 3 As shown, the flipping component 22 in this embodiment includes:
[0071] Support leg 221 is set on the bottom surface of support rod 21, located near mold 3, and its top is fixedly connected to support rod 21.
[0072] The flip-out support leg 223 is bent and located at the bottom of the support leg 221. The top of the support leg 221 is integrally connected to the support leg 221, and the bottom is in contact with the ground.
[0073] The roller 222 is located inside the flip-up foot 223, is rotatably connected to the flip-up foot 223, and is in contact with the ground.
[0074] When lifting the support rod 21, first step on the fulcrum position where the flipping support foot 223 contacts the ground with your toes, causing the support rod 21 to rotate around the fulcrum. Then, the support rod 21 can be easily flipped, achieving a smooth flipping and quick demolding process. Before flipping, press down and then push the support rod 21 to move the roller 222, thereby pushing the tool to the vicinity of the mold 3, saving time and effort.
[0075] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the flip-up foot 223 and the support leg 221 form a hook shape. When the frame rod 21 is pressed down and pushed, the flip-up foot 223 can easily rotate relative to the ground, and the roller 222 can easily roll on the ground.
[0076] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the side of the flipping support 223 in this embodiment is ∠-shaped. During the flipping process, the toes can easily step on the tip of the flipping support 223, and the flipping support 223 forms a fulcrum with the ground. It will also cause the frame rod 21 to naturally tilt up, so as to easily flip the frame rod 21 and invert the mold 3.
[0077] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, there are 4 sets of sliding components 12, which are located in the middle of the demolding frame 11 and near the flipping component 22. The sliding component 12 located in the middle of the demolding frame 11 can be engaged with the support rod 21 through the stop block 212, thereby limiting the position of the demolding frame 11 on the support rod 21 and achieving the purpose of clamping the mold 3 with the support rod 21.
[0078] Specifically, such as Figure 1 and Figure 2 As shown, the support rod 21 in this embodiment is bent, and the included angle of the bent part is in the range of 120°-150°. When the bent support rod 21 within this angle range is flipped, the hand can exert a small force, which has the characteristic of saving effort.
[0079] Please combine Figures 1-8 The entire demolding process in this embodiment is described as follows:
[0080] Press down and push the support rod 21, pushing the tool towards the mold 3. When the front end of the support rod 21 approaches the mold 3, pull the demolding frame 11 in the opposite direction, causing the demolding frame 11 to drive the sliding component 12 away from the mold 3 on the track 211. At this time, adjust the direction of the support rod 21 so that it is aligned with the mold 3, push the support rod 21 to move to both sides of the mold 3, and slide the demolding frame 11 to the top of the mold 3. When the sliding rod 123 and the sliding column 121 enter the cavity, the engagement is completed. Then, step on the flipping support foot 223 to form a temporary fulcrum with the ground. At this time, lift the support rod 21, and the support rod 21 can rotate around the fulcrum and flip. When the support rod 21 is parallel to the ground and the mold 3 is upside down on the ground, the concrete cover plate 4 can be removed from the mold 3. Finally, pull the demolding frame 11 in the opposite direction to separate the sliding component 12 from the support rod 21, and the mold 3 can be directly removed from the tool, thus completing the demolding process.
[0081] In summary, the tool consisting of the sliding device 1 and the flipping device 2 achieves the flipping of the concrete cover plate 4 by relatively sliding and clamping the mold 3 and forming a temporary fulcrum for rotation in place, allowing the flipping device 2 to rotate around the fulcrum. It is simple and easy to operate, not only replacing the trouble of manually flipping the mold 3 for demolding, but also featuring a simple structure and user-friendly design, reducing the workload of manual demolding and improving work efficiency.
[0082] This specific embodiment is merely an explanation of the utility model and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection of this utility model.
