Description

Technical Field

[0001] This utility model relates to the field of concrete pipe pile mold technology, specifically a mold for producing high-strength concrete pipe piles. Background Technology

[0002] Concrete pipe pile embedded parts are key components in the pile structure, mainly used to connect external structures or auxiliary devices to ensure the overall stability and functionality of the project. Concrete pipe pile molds are required during the production of concrete pipe piles.

[0003] A search revealed a Chinese patent (CN216099603U) that discloses a mold for producing high-strength concrete pipe piles. The mold includes a lower mold with a first reinforcing block fixed to its upper part. The first reinforcing block has a first sliding groove on its outer surface. The upper end of the lower mold has grooves on its front and rear edges, with bolts installed inside the grooves and springs installed outside the bolts. The lower mold is threadedly connected to the upper mold via bolts and threaded holes. However, during demolding, workers need to use tools to disassemble the bolts one by one. After disassembling the bolts, the pipe pile needs to be separated from the mold, increasing the difficulty of the work and reducing the pipe pile production progress. Therefore, we propose a mold for producing high-strength concrete pipe piles. Utility Model Content

[0004] The technical problem to be solved by this application is that during demolding, workers need to use tools to remove the bolts one by one. After removing the bolts, the pipe piles need to be separated from the mold, which increases the difficulty of the workers' work and reduces the production progress of the pipe piles.

[0005] To solve the above-mentioned technical problems, this application provides a mold for producing high-strength concrete pipe piles, including a lower mold and an upper mold, wherein multiple side plates are installed at equal intervals at both ends of the lower mold and the upper mold;

[0006] Rotating rods are installed on both sides of the top of the side plates at both ends of the upper mold. The lower ends of the multiple rotating rods are equipped with rotating mechanisms. The top of the rotating rods at both ends are rotatably connected to connecting plates. The bottom of the connecting plates is equipped with pressing mechanisms. The rotating mechanisms drive the multiple rotating rods to rotate simultaneously, so as to separate the side plates at both ends of the lower mold. In conjunction with the pressing mechanisms, the pipe pile is pushed away from the upper mold, so as to demold the pipe pile.

[0007] In some embodiments, fixing plates are installed on both sides of the lower mold and the upper mold, and the inner side of the fixing plate is provided with a slot adapted to the size of the reinforcing cage.

[0008] In some embodiments, the rotating mechanism includes a rotating cylinder rotatably mounted on the top of the side plates at both ends of the upper mold, the inner side of the rotating cylinder being threadedly connected to the lower end of the rotating rod, a first bevel gear being mounted on the outer side of the rotating cylinder, and a threaded groove adapted to the size of the lower end of the rotating rod being opened on the top of the side plates at both ends of the lower mold.

[0009] In some embodiments, the rotating mechanism further includes a second bevel gear meshing with the first bevel gear, a connecting rod is installed through a plurality of the second bevel gears, and support blocks are installed on both sides of the top of the two end plates of the upper mold. One end of the connecting rod is rotatably connected to one of the support blocks, and a handle is installed at the other end of the connecting rod that passes through the other support block.

[0010] In some embodiments, the pressing mechanism includes fixed rods installed at both ends of the top of the upper mold. A transmission rod is rotatably installed at the upper end of the fixed rod. Sliding holes are provided at both ends of the transmission rod. A first slider is slidably connected to one end of the sliding hole. The first slider is hinged to the bottom of the connecting plate. A second slider is slidably connected to the other end of the sliding hole. A push rod is hinged to the outside of the second slider. A push plate is installed inside the upper mold through the push rod. A groove adapted to the size of the push plate is provided on the inner side of the upper mold.

[0011] In some embodiments, multiple rotating plates are also equidistantly installed on the outer sides of the lower mold and the upper mold, the rotating plates being located between adjacent side plates and having gaps between them.

[0012] In some embodiments, the two ends of the rotating plate are provided with rotating holes that are adapted to the size of the connecting rod.

[0013] This utility model has at least the following beneficial effects:

[0014] By rotating the handle, multiple rotating rods can be rotated simultaneously through the cooperation of the connecting rod, the second bevel gear, the first bevel gear, and the rotating cylinder. This facilitates the disassembly of the upper and lower molds. When the rotating rods rotate, they move upward, causing the connecting plate to move upward. Through the cooperation of the first slider, the second slider, the rotating rod, and the push rod, the push plate is driven to push the pipe pile, causing the pipe pile to detach from the upper mold. This reduces the difficulty of the workers' work and thus improves the production progress of the pipe pile. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-5 This utility model provides a technical solution: a mold for producing high-strength concrete pipe piles, including a lower mold 1 and an upper mold 2, with multiple side plates 3 installed at equal intervals at both ends of the lower mold 1 and the upper mold 2.

[0026] Rotating rods 4 are set on both sides of the top of the side plates 3 at both ends of the upper mold 2. The lower ends of multiple rotating rods 4 are equipped with rotating mechanisms 5. The top of the rotating rods 4 at both ends is rotatably connected to connecting plates 6. The bottom of the connecting plates 6 is equipped with pressing mechanisms 7. The rotating mechanisms 5 drive multiple rotating rods 4 to rotate simultaneously, so as to separate the side plates 3 at both ends of the lower mold 1. In conjunction with the pressing mechanisms 7, the pipe pile is pushed away from the upper mold 2 to achieve demolding of the pipe pile.

[0027] The rotating mechanism 5 includes a rotating cylinder 9 rotatably mounted on the top of the side plates 3 at both ends of the upper mold 2. The inner side of the rotating cylinder 9 is threadedly connected to the lower end of the rotating rod 4. A first bevel gear 10 is mounted on the outer side of the rotating cylinder 9. The top of the side plates 3 at both ends of the lower mold 1 is provided with a threaded groove 301 that matches the size of the lower end of the rotating rod 4.

[0028] The rotating mechanism 5 also includes a second bevel gear 11 that meshes with the first bevel gear 10. A connecting rod 12 is installed through the multiple second bevel gears 11. Support blocks 13 are installed on both sides of the top of the side plates 3 at both ends of the upper mold 2. One end of the connecting rod 12 is rotatably connected to one of the support blocks 13. A handle 1201 is installed on the other end of the connecting rod 12 that passes through the other support block 13.

[0029] When demolding, turn the handle 1201. The handle 1201 drives the connecting rod 12 to rotate. The connecting rod 12 drives the second bevel gear 11 to rotate. The second bevel gear 11 drives multiple first bevel gears 10 to rotate. The multiple first bevel gears 10 drive multiple rotating cylinders 9 to rotate. The multiple rotating cylinders 9 drive multiple rotating rods 4 to rotate and disengage from the threaded groove 301, thereby releasing the fixation of the lower mold 1 and the upper mold 2.

[0030] The pressing mechanism 7 includes fixed rods 14 installed at both ends of the top of the upper mold 2. A transmission rod 15 is rotatably installed at the upper end of the fixed rod 14. Both ends of the transmission rod 15 are provided with sliding holes 1501. A first slider 16 is slidably connected to one end of the sliding hole 1501. The first slider 16 is hinged to the bottom of the connecting plate 6. A second slider 17 is slidably connected to the other end of the sliding hole 1501. A push rod 18 is hinged to the outside of the second slider 17. A push plate 19 is installed inside the upper mold 2 through the push rod 18. A groove 201 with a size matching the push plate 19 is provided on the inner side of the upper mold 2.

[0031] When the rotating rod 4 rotates, it drives the connecting plate 6 to move upward. The connecting plate 6 drives the first slider 16 to slide in the sliding hole 1501 at one end of the transmission rod 15, which drives the transmission rod 15 to rotate. The transmission rod 15 drives the second slider 17 to slide in the sliding hole 1501 at the other end. The second slider 17 drives the push rod 18 to slide upward and inward into the mold 2. The push rod 18 drives the push plate 19 to slide and squeeze the pipe pile, so that the pipe pile is separated from the upper mold 2, thereby reducing the demolding time and improving the production progress of the pipe pile.

[0032] Both sides of the lower mold 1 and the upper mold 2 are equipped with fixing plates 8. The inner side of the fixing plate 8 is provided with a slot 801 that matches the size of the steel cage. The steel cage is limited by the slot 801 to prevent the steel cage from deforming and shifting when concrete is poured after the steel cage is placed.

[0033] Multiple rotating plates 20 are also installed at equal intervals on the outer sides of the lower mold 1 and the upper mold 2. The rotating plates 20 are located between adjacent side plates 3 and have gaps between them. The two ends of the rotating plates 20 are provided with rotating holes 2001 that are adapted to the size of the connecting rod 12. The rotating plates 20 are used to engage with the external centrifuge.

[0034] Example 2

[0035] Please see Figure 6 and Figure 7 The present invention provides a technical solution: Based on embodiment 1, the present invention provides another technical solution: a rubber strip 21 is installed at the bottom of the upper mold 2, and a sealing groove 101 adapted to the size of the rubber strip 21 is opened at the top of the lower mold 1. When the upper mold 2 and the lower mold 1 are fitted together, the rubber strip 21 is stuck in the sealing groove 101, which increases the sealing between the lower mold 1 and the upper mold 2.
