Description

Technical Field

[0001] This invention belongs to the field of precast beam demolding technology, and specifically relates to a demolding device for precast beam production. Background Technology

[0002] Precast beams are concrete beam components that are prefabricated in a factory or on a construction site and then transported to the designed location for installation. They are mainly used in building and bridge engineering and are characterized by standardized production and high construction efficiency. Precast beams are beam structures that are prefabricated in a factory or on a construction site, with concrete pouring and curing completed in advance, and then transported to the site for installation after the strength meets the standards.

[0003] After the precast beam reaches its hardness, the mold needs to be removed. Before the precast beam is constructed, a release agent is applied to the contact area between the mold and the precast beam to facilitate the removal of the mold after the precast beam is completed. However, in actual operation, after loosening the fastening bolts, the mold is not easy to separate directly from the precast beam. Therefore, it is necessary to manually use a rubber hammer to strike the mold to separate it from the precast beam. However, during the process of striking the side mold, the mold suddenly separates from the precast beam. The mold is heavy and falls when workers are nearby, posing a significant safety hazard.

[0004] Therefore, we propose a demolding device for precast beam production to solve the above problems. Summary of the Invention

[0005] To address the above problems, the present invention provides a demolding device for precast beam production, including a bracket, a support mechanism for placing the mold, and an impact mechanism for striking the mold. The support mechanism includes a support plate for placing the mold and a buffer mechanism, the buffer mechanism being used to provide cushioning for the mold.

[0006] The impact mechanism is mounted on the bracket;

[0007] The impact mechanism includes an impact rod and a cylinder. The impact rod is installed on the telescopic end of the cylinder and is used to impact the mold. The cylinder is slidably mounted on the bracket.

[0008] The impact rod includes a first movable rod, a first fixed tube, and a first spring. The first fixed tube is fixedly installed at the telescopic end of the cylinder. One end of the first movable rod is fixedly connected to a first piston. The first piston is slidably installed inside the first fixed tube. One end of the first spring is fixedly connected to the first fixed tube. The other end of the first spring is fixedly connected to one side of the first piston. The first fixed tube is connected to a follower that can collide with the mold.

[0009] In one embodiment of this application, the buffer mechanism includes a movable component, a hydraulic damper, and a support plate. The hydraulic damper is mounted on the movable component, and the support plate is fixedly mounted on the telescopic end of the hydraulic damper.

[0010] In one embodiment of this application, the driven member includes a second fixed tube, a second movable rod, and a second spring. One end of the second movable rod is fixedly connected to a second piston, the second piston is slidably installed inside the second fixed tube, one end of the second spring is fixedly connected to the second fixed tube, and the other end of the second spring is fixedly connected to the side of the second piston. The first fixed tube communicates with the second fixed tube.

[0011] In one embodiment of this application, the moving component includes a guide rail and a slider, the slider being slidably mounted within the guide rail, the hydraulic damper being fixedly mounted on the slider, and the guide rail being fixedly mounted on the ground.

[0012] In one embodiment of this application, one end of both the first movable rod and the second movable rod is provided with a first flexible pad for flexible contact with the mold.

[0013] In one embodiment of this application, an electric slide is fixedly mounted on the bracket, and the cylinder is fixedly mounted on the sliding block of the electric slide.

[0014] In one embodiment of this application, an electric push rod is fixedly installed on one side of the slider, and one end of the electric push rod is fixedly installed on the ground;

[0015] The electric push rod is used to drive the slider to move along the guide rail.

[0016] In one embodiment of this application, a second flexible pad is provided on the pallet, which is used to flexibly release the pallet from the mold.

[0017] In one embodiment of this application, the buffer mechanism is provided in a plurality of units, and the plurality of hydraulic dampers are fixedly connected by connecting rods.

[0018] In one embodiment of this application, a support rod is fixedly connected to the slider, and the second fixing tube is fixedly installed on the upper end of the support rod;

[0019] A sleeve is slidably fitted onto the support rod, and the sleeve is fixedly connected to the support plate.

[0020] The beneficial effects of this invention are:

[0021] 1. When the cylinder is working, the extension and retraction end of the cylinder drives the impact rod to move. The first movable rod contacts and collides with the side of the mold. When the first movable rod contacts the side of the mold, the first spring is compressed and pushes the first piston to move in the first fixed tube, thereby squeezing the air in the first fixed tube and buffering the impact generated during the collision. This can reduce the impact force of the first movable rod on the mold and effectively avoid damage to the mold.

[0022] 2. When the mold is dropped by the first movable rod, the support plate catches the falling mold. When the mold is supported by the support plate, the impact force of the falling mold impacts the support plate, thereby compressing the hydraulic damper and absorbing the impact energy. This can reduce the vibration generated when the mold falls onto the support plate and provide buffer protection for the mold. It can effectively prevent the mold from falling directly to the ground and causing mold deformation.

[0023] 3. Through the driven member, the first piston compresses the air in the first fixed tube into the second fixed tube. The air entering the second fixed tube pushes the second piston, thereby causing the second movable rod to move along the second fixed tube. The second movable rod strikes the mold. Through the use of the second spring, the impact generated during the strike can be absorbed, which can effectively provide buffer protection for the mold when it is impacted. The mold can be struck from multiple directions, improving the striking efficiency. At the same time, it provides buffer protection during the strike, effectively avoiding damage to the mold.

[0024] When the cylinder retracts, it drives the impact rod to reset, and the first spring pushes the first piston to reset. During this process, the first piston draws back the air that has entered the second fixed tube. After the air in the second fixed tube is reduced, the second spring pulls the second piston to reset, thereby separating the second movable rod from the mold, thus completing one strike. The cylinder works repeatedly, so that the first and second movable rods can repeatedly strike the mold until the mold separates from the precast beam. This can reduce manual operation, reduce the labor intensity of workers, and reduce the risks caused by manual operation.

[0025] 4. By using the moving parts, when demolding precast beams of various sizes, the electric push rod works to push the slider to move on the guide rail, which can move the pallet to the bottom of the mold. At the same time, it can also move the driven parts closer to the mold and keep them aligned with the impact rod. When the impact rod strikes the mold, the second moving rod can also strike the mold at the same time, which can effectively improve the applicability of the device.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] See Figure 1 , Figure 2 , Figure 4 and Figure 5 This invention provides a demolding device for precast beam production, including a bracket 1, a support mechanism for placing the mold, and an impact mechanism 2 for striking the mold. The support mechanism includes a support plate 3 for placing the mold and a buffer mechanism 4, which provides buffering for the mold.

[0038] The impact mechanism 2 is mounted on the bracket 1;

[0039] The impact mechanism 2 includes an impact rod 5 and a cylinder 6. The impact rod 5 is installed on the telescopic end of the cylinder 6. The impact rod 5 is used to collide with the mold. The cylinder 6 is slidably installed on the bracket 1.

[0040] The impact rod 5 includes a first movable rod 7, a first fixed tube 8, and a first spring 9. The first fixed tube 8 is fixedly installed at the telescopic end of the cylinder 6. One end of the first movable rod 7 is fixedly connected to a first piston 10, which is slidably installed inside the first fixed tube 8. One end of the first spring 9 is fixedly connected inside the first fixed tube 8, and the other end of the first spring 9 is fixedly connected to one side of the first piston 10. The first fixed tube 8 is connected to a follower 11 that can collide with the mold.

[0041] An electric slide 21 is fixedly mounted on the bracket 1, and a cylinder 6 is fixedly mounted on the sliding block of the electric slide 21.

[0042] It should be noted that the support plate 3 is located below the bracket 1.

[0043] Using the above scheme, when the cylinder 6 is working, the telescopic end of the cylinder 6 drives the impact rod 5 to move, and the first movable rod 7 contacts and collides with the side of the mold. When the first movable rod 7 contacts the side of the mold, the first spring 9 is compressed by force, pushing the first piston 10 to move in the first fixed tube 8, thereby squeezing the air in the first fixed tube 8 and buffering the impact generated during the collision. This can reduce the impact force of the first movable rod 7 on the mold and effectively avoid damage to the mold.

[0044] See Figure 1 , Figure 3 , Figure 6 and Figure 7 In this embodiment, the buffer mechanism 4 includes a moving part, a hydraulic damper 12 and a support plate 13. The hydraulic damper 12 is mounted on the moving part, and the support plate 13 is fixedly mounted on the telescopic end of the hydraulic damper 12.

[0045] It should be noted that the movable component can move the pallet 13 to the bottom of the mold.

[0046] Using the above scheme, through the use of the buffer mechanism 4, when the mold is hit and dropped by the first movable rod 7, the support plate 13 catches the falling mold. When the support plate 13 supports the mold, the impact force of the mold falling impacts the support plate 13, thereby compressing the hydraulic damper 12 and absorbing the impact energy. This can reduce the vibration generated when the mold falls onto the support plate 13, provide buffer protection for the mold, and effectively prevent the mold from falling directly to the ground and causing mold deformation.

[0047] See Figure 6 and Figure 7 In this embodiment, the driven member 11 includes a second fixed tube 14, a second movable rod 15, and a second spring 16. One end of the second movable rod 15 is fixedly connected to a second piston 17, which is slidably installed inside the second fixed tube 14. One end of the second spring 16 is fixedly connected to the second fixed tube 14, and the other end of the second spring 16 is fixedly connected to the side of the second piston 17. The first fixed tube 8 communicates with the second fixed tube 14.

[0048] It should be noted that guide grooves are provided on the inner walls of the first fixed tube 8 and the second fixed tube 14. Guide blocks that slide in cooperation with the guide grooves are fixedly connected to the sides of the first movable rod 7 and the second movable rod 15. The cooperation between the guide blocks and the guide grooves can keep the first movable rod 7 and the second movable rod 15 stable during extension and retraction.

[0049] Using the above scheme, through the follower 11, the air in the first fixed tube 8 is squeezed into the second fixed tube 14 by the first piston 10. The air entering the second fixed tube 14 pushes the second piston 17, thereby causing the second movable rod 15 to move along the second fixed tube 14. The second movable rod 15 strikes the mold. With the use of the second spring 16, the energy generated during the strike can be absorbed, which can effectively provide buffer protection for the mold when it is impacted. The mold can be struck from multiple directions, improving the striking efficiency. At the same time, it provides buffer protection during the strike, effectively avoiding damage to the mold.

[0050] When the telescopic end of cylinder 6 retracts, it drives the impact rod to reset, and the first spring 9 pushes the first piston 10 to reset. During this process, the first piston 10 draws back the air that has entered the second fixed tube 14. After the air in the second fixed tube 14 is reduced, the second spring 16 pulls the second piston 17 to reset, thereby separating the second movable rod 15 from the mold, thus completing one strike. Cylinder 6 works repeatedly, so that the first movable rod and the second movable rod 15 can repeatedly strike the mold until the mold separates from the precast beam. This can reduce manual operation, reduce the labor intensity of workers, and reduce the risks caused by manual operation.

[0051] See Figure 6 In this embodiment, the moving component includes a guide rail 18 and a slider 19. The slider 19 is slidably mounted in the guide rail 18, the hydraulic damper 12 is fixedly mounted on the slider 19, and the guide rail 18 is fixedly mounted on the ground.

[0052] A support rod 24 is fixedly connected to the slider 19, and the second fixing tube 14 is fixedly installed on the upper end of the support rod 24;

[0053] An electric push rod 22 is fixedly installed on one side of the slider 19, and one end of the electric push rod 22 is fixedly installed on the ground.

[0054] The electric push rod 22 is used to drive the slider 19 to move along the guide rail 18;

[0055] A sleeve 25 is slidably sleeved on the support rod 24, and the sleeve 25 is fixedly connected to the support plate 13.

[0056] It should be noted that when the mold is caught by the pallet 13, if the mold falls off the pallet 13, the support rod 24 can act as a stop, effectively preventing the mold from falling to the location of the electric push rod 22.

[0057] By adopting the above scheme, when demolding precast beams of various sizes, the electric push rod 22 works to push the slider 19 to move on the guide rail 18, which can move the support plate 13 to the bottom of the mold. At the same time, it can also move the driven part 11 closer to the mold and keep it aligned with the impact rod 5. When the impact rod strikes the mold, the second movable rod 15 can also strike the mold at the same time, which can effectively improve the applicability of the device.

[0058] Specifically, one end of both the first movable rod 7 and the second movable rod 15 is provided with a first flexible pad 20 for flexible contact with the mold.

[0059] It should be noted that the first flexible pad 20 includes, but is not limited to, a rubber pad.

[0060] Specifically, a second flexible pad 23 is provided on the pallet 13, which is used to flexibly release the pallet 13 from the mold.

[0061] It should be noted that the second flexible pad 23 includes, but is not limited to, a rubber pad.

[0062] Specifically, the buffer mechanism 4 is provided in several units, and the hydraulic dampers 12 are fixedly connected by connecting rods.

[0063] It should be noted that there are at least two buffer mechanisms 4;

[0064] Connecting the hydraulic damper 12 into a whole via a connecting rod can improve the stability of the hydraulic damper 12.

[0065] The above embodiments have the following beneficial effects:

[0066] 1. When the cylinder 6 is working, the telescopic end of the cylinder 6 drives the impact rod 5 to move, and the first movable rod 7 contacts and collides with the side of the mold. When the first movable rod 7 contacts the side of the mold, the first spring 9 is compressed by force, pushing the first piston 10 to move in the first fixed tube 8, thereby squeezing the air in the first fixed tube 8 and buffering the impact generated during the collision. This can reduce the impact force of the first movable rod 7 on the mold and effectively avoid damage to the mold.

[0067] 2. When the mold is dropped by the first movable rod 7, the support plate 13 catches the falling mold. When the support plate 13 supports the mold, the impact force of the falling mold impacts the support plate 13, thereby compressing the hydraulic damper 12 and absorbing the impact energy. This can reduce the vibration generated when the mold falls onto the support plate 13, provide buffer protection for the mold, and effectively prevent the mold from falling directly to the ground and causing mold deformation.

[0068] 3. Through the follower 11, the air in the first fixed tube 8 is squeezed into the second fixed tube 14 by the first piston 10. The air entering the second fixed tube 14 pushes the second piston 17, thereby causing the second movable rod 15 to move along the second fixed tube 14. The second movable rod 15 strikes the mold. With the use of the second spring 16, the impact generated during the strike can be absorbed, which can effectively provide buffer protection for the mold when it is impacted. The mold can be struck in multiple directions, improving the striking efficiency. At the same time, it provides buffer protection during the strike, effectively avoiding damage to the mold.

[0069] When the telescopic end of cylinder 6 retracts, it drives the impact rod to reset, and the first spring pushes the first piston to reset. During this process, the first piston draws back the air that has entered the second fixed tube. After the air in the second fixed tube is reduced, the second spring pulls the second piston to reset, thereby separating the second movable rod from the mold, thus completing one strike. Cylinder 6 works repeatedly, so that the first and second movable rods can repeatedly strike the mold until the mold separates from the precast beam. This can reduce manual operation, reduce the labor intensity of workers, and reduce the risks caused by manual operation.

[0070] 4. By using the movable component, when demolding precast beams of various sizes, the electric push rod 22 works to push the slider 19 to move on the guide rail 18, which can drive the pallet 13 to move below the mold. At the same time, it can drive the driven component 11 to move closer to the mold and keep in alignment with the impact rod 5. When the impact rod strikes the mold, the second movable rod 15 can also strike the mold at the same time, which can effectively improve the applicability of the device.
