Description

Technical Field

[0001] This application belongs to the field of concrete demolding technology, specifically a rapid demolding device for concrete pipe pile molds. Background Technology

[0002] Reinforced concrete prestressed pipe piles, also known as precast concrete piles, are prefabricated in a precast component processing plant, cured to the design strength, transported to the construction site, and driven into the soil using a pile driver. A foundation beam (slab) is then poured on top of the pile. The concrete grade used for reinforced concrete precast piles should not be lower than 300#. The diameter of the reinforcing steel bars in the pile should not be less than 12 mm, and generally 4 to 8 main bars are configured. To resist hammering and penetrate soil layers, the stirrups should be denser at the pile top and tip, and the main bars at the pile tip should be bent up and welded to a mandrel. Reinforced concrete precast piles have the advantages of simple manufacturing, high strength, high rigidity, and the ability to be made into various cross-sectional shapes, making them a widely used pile type.

[0003] Referring to CN218748484U, a concrete pipe pile demolding device is described. It includes a support frame and a handle. The support frame is equipped with a guide rail, a sliding rod is slidably fitted onto the guide rail, and a fixed plate is slidably fitted onto the sliding rod. The fixed plate is hinged to a first gear, which meshes with several screwdrivers. A second gear is fixedly connected to the end face of the first gear away from the screwdrivers. The second gear meshes with a third gear, and the third gear is hinged to a handle. A connecting device is provided at the central axis of the third gear. This invention, by setting multiple screwdrivers and linking them with gears, allows the device to disassemble multiple bolts simultaneously. Furthermore, by setting the handle and connecting device, the device can achieve demolding of concrete pipe piles using both mechanical and manual power methods, effectively improving the efficiency of concrete pipe pile demolding and effectively reducing the dangers of concrete pipe pile demolding.

[0004] In addition to bolts, retaining rings can also be fixed to concrete pipes by adhesive. They can be removed by tools or high-pressure water guns. During concrete pipe production, retaining rings are usually installed at both ends of the mold, forming a closed structure with the mold body to fix the axial dimensions of the concrete pipe. When demolding, the mold must be separated from the formed concrete pipe. If the retaining rings are not removed, the mold cannot be pulled out from both ends of the pipe, resulting in demolding failure.

[0005] However, the following problems still exist: when separating the retaining ring and the concrete pipe, it is necessary to manually knock and vibrate to remove the concrete adhering to the gap between the retaining ring and the concrete pipe, and then separate the retaining ring and the concrete. There are no supporting parts during the separation, and the retaining ring quickly falls off the concrete pipe after separation. Due to the large weight of the retaining ring, relying on manual lifting poses a significant safety hazard. Utility Model Content

[0006] The purpose of this application is to provide a rapid demolding device for concrete pipe pile molds, which addresses the problem that when separating the retaining ring and the concrete pipe, manual hammering and vibration are required to remove the adhesive concrete adhering to the gap between the retaining ring and the concrete pipe, thereby separating the retaining ring and the concrete. In this case, there are no supporting components during separation, and the retaining ring quickly falls off the concrete pipe after separation. Due to the large weight of the retaining ring, relying on manual lifting poses a significant safety hazard.

[0007] The technical solution adopted in this application is as follows: A quick demolding device for concrete pipe pile molds includes a base plate and a pipe pile body. A retaining ring is bonded to the surface of the pipe pile body. A bracket is fixedly connected to the upper surface of the base plate. A driving column is rotatably connected to the side of the bracket. A disc is fixedly connected to the end of the driving column away from the bracket. A fixing plate is fixedly connected to the upper surface of the base plate. The fixing plate is rotatably connected to the surface of the driving column. A through hole is opened on the side of the disc. A support plate is slidably connected to the side of the fixing plate. A limit rod is fixedly connected to the side of the support plate away from the fixing plate. The through hole is sleeved on the surface of the limit rod.

[0008] Preferably, there are three support plates, and the three support plates are arranged in a circular array on the side of the fixed plate. By setting the number of support plates to three, they can be arranged in a triangular array to support the inner ring surface of the limiting rod, which can stably support the limiting rod.

[0009] Preferably, a pad is fixedly connected to the side of the support plate away from the disc. The pad is made of rubber. By setting the pad to be made of rubber, the friction between the support plate and the inner ring surface of the retaining ring can be increased, reducing the occurrence of the retaining ring sliding on the support plate when the bottom plate pulls the retaining ring away from the pipe pile body.

[0010] Preferably, a push rod is fixedly connected to the side of the bracket away from the driving column, and a handle is fixedly connected to the side of the push rod away from the bracket. A universal caster with brake is rotatably connected to the lower surface of the base plate. By providing the handle, the base plate can be pushed by the push rod, and the base plate can be moved by the universal caster with brake after being pushed, thereby facilitating the handling of the fixed plate.

[0011] Preferably, a horizontal plate is fixedly connected to the opposite surfaces of the fixing plate and the bracket. A limiting hole is opened on the upper surface of the driving column. A rod is provided on the inner wall of the limiting hole, and the rod passes through the upper surface of the horizontal plate. When the support plate is supported on the inner ring surface of the retaining ring, the rod is inserted into the limiting hole to limit the limiting hole, so as to avoid the situation where the driving column rotates and the support plate moves, which would not be able to support the retaining ring tightly and cause the retaining ring to fall off the support plate.

[0012] Preferably, the sides of the base plate are fixedly connected to an inclined block and a support plate, respectively. The upper surface of the support plate is provided with a groove, and the bottom wall of the inner wall of the groove is fixedly connected to a spring. The end of the spring away from the bottom wall of the inner wall of the groove is fixedly connected to the lower surface of the stop block. During the process of pushing the base plate to push the support plate into the inner ring of the retaining ring, the stop block is squeezed into the groove by the retaining ring, and the spring is compressed until the support plate enters the retaining ring. At this time, the stop block passes the retaining ring and is located on the right side of the retaining ring. Then, the spring returns to its original position and pushes the stop block upward. When the retaining ring is being transported, the support plate supports the retaining ring, and the upward movement of the stop block blocks the right side of the retaining ring, reducing the occurrence of the retaining ring falling off during transportation.

[0013] Preferably, a turntable is fixedly connected to the end of the driving column away from the fixed plate. By setting the turntable, it is convenient for the user to drive the driving column to rotate, thereby driving the retaining ring to rotate.

[0014] Preferably, the through holes are arc-shaped and there are three of them, which correspond to the position of the support plate. By setting the shape of the through holes to arc, it is easy to squeeze and push the limiting rod to move when the retaining ring rotates, thereby driving the support plate to move.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0016] 1. In this application, the base plate is pushed close to the main body of the pipe pile. At this time, the inclined block lifts one side of the retaining ring. After the support plate enters the retaining ring, the turntable is rotated. The rotation of the turntable drives the rotating column to rotate, which in turn drives the disc to rotate. When the disc rotates, the through hole rotates and squeezes the limiting rod, pushing the pad to move. The pad moves and supports the inner ring surface of the retaining ring, tightening the retaining ring. Then, the insertion rod is inserted into the limiting insertion hole to limit the rotating column. Then, the connection between the retaining ring and the main body of the pipe pile is struck by an external tool. After the retaining ring and the main body of the pipe pile separate, the base plate is pulled, and the retaining ring moves away from the main body of the pipe pile. This solves the problem of safety hazards when the retaining ring detaches from the main body of the pipe pile to a certain extent. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Example:

[0026] Reference Figure 2-6 A quick demolding device for concrete pipe pile molds includes a base plate 1 and a pipe pile body 10. A retaining ring 11 is bonded to the surface of the pipe pile body 10. A support 2 is fixedly connected to the upper surface of the base plate 1. A driving column 6 is rotatably connected to the side of the support 2. The retaining ring 11 is fixedly connected to the end of the driving column 6 away from the support 2. A fixing plate 7 is fixedly connected to the upper surface of the base plate 1 and rotatably connected to the surface of the driving column 6. A through hole 12 is opened on the side of the retaining ring 11. A support plate 14 is slidably connected to the side of the fixing plate 7. A limit rod 13 is fixedly connected to the side of the support plate 14 away from the fixing plate 7. The through hole 12 is sleeved on the surface of the limit rod 13. Pushing the base plate 10... When plate 1 approaches the main body 10 of the pipe pile, the inclined block 16 lifts one side of the retaining ring 11. After the support plate 14 enters the retaining ring 11, it drives the column 6 to rotate and the disc 23 to rotate. When the disc 23 rotates, the through hole 12 rotates and squeezes the limiting rod 13, and pushes the pad 15 to move. The pad 15 moves and supports the inner ring surface of the retaining ring 11, and after the retaining ring 11 is tightened, the insert rod 9 is inserted into the limiting insert 22 to limit the column 6. Then, the connection between the retaining ring 11 and the main body 10 of the pipe pile is struck by an external tool. After the retaining ring 11 and the main body 10 of the pipe pile are separated, the bottom plate 1 is pulled. The bottom plate 1 drives the retaining ring 11 to move away from the main body 10 of the pipe pile through the fixing plate 7.

[0027] Reference Figure 1-3There are three support plates 14, which are arranged in a circular array on the side of the fixed plate 7. By setting the number of support plates 14 to three, they can be arranged in a triangular array to support the inner ring surface of the limiting rod 13, thus stably supporting the limiting rod 13. A pad 15 is fixedly connected to the side of the support plate 14 away from the retaining ring 11. The pad 15 is made of rubber. By setting the material of the pad 15 to rubber, the friction between the support plate 14 and the inner ring surface of the retaining ring 11 can be increased, reducing the occurrence of the retaining ring 11 sliding on the support plate 14 when the bottom plate 1 pulls the retaining ring 11 away from the pipe pile body 10.

[0028] Reference Figure 3-5 A push rod 3 is fixedly connected to the side of the bracket 2 away from the driving column 6. A handle 4 is fixedly connected to the side of the push rod 3 away from the bracket 2. A universal wheel 21 with brake is rotatably connected to the lower surface of the base plate 1. By setting the handle 4, the base plate 1 can be pushed by the push rod 3. After the base plate 1 is pushed, it moves by the universal wheel 21 with brake, which facilitates the handling of the fixed plate 7, increases the handling efficiency of the retaining ring 11 during demolding, and thus speeds up the demolding time of the tube body 10.

[0029] Reference Figure 1-3 A horizontal plate 8 is fixedly connected to the opposite surfaces of the fixed plate 7 and the bracket 2. A limit insertion hole 22 is opened on the upper surface of the driving column 6. A rod 9 is provided on the inner wall of the limit insertion hole 22 and passes through the upper surface of the horizontal plate 8. When the support plate 14 is supported on the inner ring surface of the retaining ring 11, the rod 9 is inserted into the limit insertion hole 22 to limit the limit insertion hole 22, so as to prevent the support plate 14 from moving due to the rotation of the driving column 6, which would not be able to support the retaining ring 11 tightly and cause the retaining ring 11 to fall off the support plate 14. An inclined block 16 and a support plate 17 are fixedly connected to the side of the base plate 1. A groove 20 is opened on the upper surface of the support plate 17. The inner wall of the groove 20 is... A spring 19 is fixedly connected to the bottom wall. One end of the spring 19 away from the bottom wall of the inner wall of the groove 20 is fixedly connected to the lower surface of the stop block 18. During the process of pushing the bottom plate 1 to push the support plate 14 into the inner ring surface of the retaining ring 11, the stop block 18 is squeezed and moved into the groove 20 by the retaining ring 11, and the spring 19 is compressed until the support plate 14 enters the retaining ring 11. At this time, the stop block 18 passes the retaining ring 11 and is located on the right side of the retaining ring 11. At this time, the spring 19 resets and pushes the stop block 18 upward. When the retaining ring 11 is being transported, the support plate 17 supports the retaining ring 11, and the upward movement of the stop block 18 blocks the right side of the retaining ring 11 to reduce the occurrence of the retaining ring 11 falling off during transportation.

[0030] Reference Figure 1-3 A turntable 5 is fixedly connected to the end of the driving column 6 away from the fixed plate 7. By setting the turntable 5, it is easy for the user to drive the driving column 6 to rotate, thereby driving the retaining ring 11 to rotate.

[0031] Reference Figure 2-4The through holes 12 are arc-shaped and there are three of them, which correspond to the position of the support plate 14. By setting the through holes 12 to be arc-shaped, when the retaining ring 11 rotates, it is easy to squeeze and push the limiting rod 13 to move, thereby driving the support plate 14 to move.

[0032] The implementation principle of the concrete pipe pile mold quick demolding device of this application is as follows: Push the base plate 1 close to the pipe pile body 10. At this time, the inclined block 16 lifts one side of the retaining ring 11. After the support plate 14 enters the retaining ring 11, the turntable 5 is rotated. The rotation of the turntable 5 drives the column 6 to rotate. The rotation of the column 6 drives the disc 23 to rotate. At this time, the rotation of the disc 23 causes the through hole 12 to rotate and squeeze the limiting rod 13, and push the pad 15 to move. The pad 15 moves and supports the inner ring surface of the retaining ring 11. After the retaining ring 11 is tightened, the insertion rod 9 is inserted into the limiting insertion hole 22 to limit the column 6. Then, the connection between the retaining ring 11 and the pipe pile body 10 is struck by an external tool. After the retaining ring 11 and the pipe pile body 10 are separated, the base plate 1 is pulled. The base plate 1 drives the retaining ring 11 to move away from the pipe pile body 10 through the fixing plate 7. This solves the problem of safety hazards when the retaining ring 11 is separated from the pipe pile body 10 to a certain extent.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
