Description

Technical Field

[0001] This invention relates to the field of concrete pipe pile technology, and more specifically to a concrete pipe pile casting mold. Background Technology

[0002] Prestressed concrete pipe piles using the pre-tensioning method have begun to be widely used in railway systems and have expanded to industrial and civil buildings, municipal works, metallurgy, ports, highways, and other fields. In certain areas, due to geological conditions suitable for the use of pipe piles, the demand for pipe piles has surged, thus rapidly forming a new industry. Pipe piles are mostly cast using pipe pile casting molds. However, traditional concrete pipe pile casting molds have relatively fixed structures, which can only be used to cast pipe piles of a certain height, resulting in poor applicability. In addition, the molds are generally large in size, which can cause transportation problems. Moreover, the demolding process is relatively complicated, which can greatly affect the processing efficiency of concrete pipe piles. Therefore, we propose a concrete pipe pile casting mold that is more applicable and easier to transport.

[0003] The existing technology has the following problems:

[0004] Existing concrete pipe pile casting molds have poor locking effect on the outer wall of the mold column tube. They often cause deformation of the mold column tube or leakage of grout at the connection between pipes due to excessive concrete pressure, thus affecting the concrete pipe pile casting effect of the casting mold. Existing concrete pipe pile casting molds are not easy to vibrate during the casting process, resulting in cavities in the cast concrete pipe pile, which also affects the casting effect of the casting mold. Summary of the Invention

[0005] The present invention provides a concrete pipe pile casting mold to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A concrete pipe pile casting mold includes a locking structure, wherein a mold column tube is clamped to the inner wall of the locking structure, the inner wall of the mold column tube is filled with concrete piles, and a drive motor is fixedly installed at the bottom of the front edge of the mold column tube.

[0008] The locking structure includes a first clamp, the inner wall of which overlaps with the outer wall of the mold column tube. A second clamp is rotatably connected to the bottom of the first clamp and located at the bottom of the outer wall of the mold column tube. A beveled pin is inserted into the right side of the front of the first clamp and the second clamp. A buckle is overlapped on the right side of the beveled pin. The bottom of the buckle is rotatably connected to the right side of the front of the second clamp. A locking block is locked at the top right side of the buckle. The right side of the locking block is fixedly connected to the right side of the front of the first clamp. A threaded sleeve is rotatably connected to the front of the first clamp. A stud is threadedly connected to the bottom of the front of the threaded sleeve. A push plate is fixedly installed at the bottom of the stud. L-shaped guide rods are fixedly installed on both sides of the upper surface of the push plate.

[0009] Gear 1 is fixedly installed on the outer wall of the drive motor rotating shaft. A ring gear meshes with the outer wall of gear 1. A clamping plate overlaps the front of the ring gear. A shaft meshes with the outer wall of the ring gear. Gear 2 is fixedly installed on the inner wall of the shaft. A chain is fixedly installed on the outside of gear 2. A rubber ball is fixedly installed at one end of the chain.

[0010] A further improvement of the technical solution of the present invention is that: a guide post is movably sleeved on the top of the L-shaped guide rod, a support spring is movably sleeved on the bottom of the outer wall of the guide post and on the right side of the L-shaped guide rod, and the upper and lower ends of the guide post are fixedly installed with the front of the first clamp.

[0011] A further improvement of the technical solution of the present invention is that: an adjusting handwheel is fixedly installed on the top of the threaded sleeve, and a hexagonal prism nut is fixedly connected to the bottom of the inner wall of the adjusting handwheel.

[0012] A further improvement of the technical solution of the present invention is that: a rubber pad is fixedly connected to the inner wall of the push plate, and the inner wall of the rubber pad overlaps with the outer wall of the mold column tube.

[0013] A further improvement of the technical solution of the present invention is that: a return spring is fixedly installed on the front of the second clamp, a push rod is fixedly installed on the left side of the return spring, the outer wall of the push rod is movably sleeved with the front of the second clamp, a roller is rotatably connected to the left side of the push rod, and the left side of the outer wall of the roller overlaps with the right side of the buckle.

[0014] A further improvement of the technical solution of the present invention is that: one side of the rubber ball overlaps with the front of the mold column tube, and the outer wall of the gear two is rotatably connected to the front of the mold column tube.

[0015] A further improvement of the technical solution of the present invention is that: guide grooves are provided on the upper and lower sides of the ring gear, steel balls are attached to the inner wall of the guide grooves, and the outer wall of the steel balls is rotatably connected to the front of the card plate.

[0016] A further improvement of the technical solution of the present invention is that: a hexagonal prism is fixedly connected to the bottom of the second gear, a guide groove post is inserted into the bottom of the hexagonal prism, and the bottom of the guide groove post is fixedly installed with the top of the second gear.

[0017] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0018] 1. This invention provides a concrete pipe pile pouring mold. By using a rubber pad, the friction between the inner wall of the push plate and the outer wall of the mold column tube is increased, avoiding the problem of the locking structure falling off the outer wall of the mold column tube. The guide post and L-shaped guide rod are used to guide the two sides of the outer wall of the push plate, preventing the stud from driving the push plate to rotate when the threaded sleeve is rotated, thus affecting the pressing effect on the outer wall of the mold column tube.

[0019] 2. This invention provides a concrete pipe pile pouring mold. When it is necessary to disassemble the locking structure, the inclined pin is removed from the connection between the right side of the first clamp and the second clamp. Then, the push rod is pushed by the action of the return spring, so that the push rod pushes the roller, causing the buckle and the locking block to separate. This allows the right side connection between the first clamp and the second clamp to be separated, thereby facilitating the disassembly of the locking structure.

[0020] 3. This invention provides a concrete pipe pile casting mold. Through the action of steel balls and guide grooves, it is convenient to drive the ring gear and reduce the wear between the outer wall of the ring gear and the inner wall of the clamping plate. The hexagonal prism and guide groove column facilitate the connection between the two gears, thereby facilitating the transmission of the two gears at the connection between the mold column tubes.

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] Example 1

[0030] like Figure 1-6 As shown, the present invention provides a concrete pipe pile casting mold, including a locking structure 1. A mold column tube 2 is clamped to the inner wall of the locking structure 1. The inner wall of the mold column tube 2 is filled with concrete piles 3. A drive motor 4 is fixedly installed at the bottom of the front edge of the mold column tube 2. The locking structure 1 includes a first clamp 11, the inner wall of which overlaps with the outer wall of the mold column tube 2. A second clamp 12 is rotatably connected to the bottom of the first clamp 11 and the bottom of the outer wall of the mold column tube 2. An inclined pin 13 is inserted into the right side of the front of the first clamp 11 and the second clamp 12. A buckle 14 overlaps the right side of the inclined pin 13. The bottom of the buckle 14 is rotatably connected to the right side of the front of the second clamp 12. A locking block 15 is clamped to the top right side of the buckle 14. The right side of the locking block 15 is fixedly connected to the right side of the front of the first clamp 11. The front of the first clamp 11 is rotatably connected to a threaded sleeve 18. The bottom of the front of the threaded sleeve 18 is threadedly connected to a stud 112. The bottom of the stud 112 is fixedly installed with a push plate 113. The two sides of the upper surface of the push plate 113 are fixedly installed with L-shaped guide rods 110. The outer wall of the rotating shaft of the drive motor 4 is fixedly installed with a gear 41. The outer wall of the gear 41 is meshed with a ring gear 42. The front of the ring gear 42 is connected to a locking plate 43. The outer wall of the ring gear 42 is meshed with a shaft 45. The inner wall of the shaft 45 is fixedly installed with a gear 46. The outside of the gear 46 is fixedly installed with a chain 47. One end of the chain 47 is fixedly installed with a rubber ball 48.

[0031] In this embodiment, the mold column tube 2 is placed in an appropriate position, and the first clamp 11 and the buckle 14 are fitted onto the appropriate position on the outer wall of the mold column tube 2. One end of the buckle 14 is inserted into the right side of the first clamp 11, so that the top of the right side of the buckle 14 is engaged with the left side of the locking block 15. Then, the inclined pin 13 is inserted into the left side of the buckle 14, which connects the right side of the first clamp 11 and the second clamp 12. Then, the adjusting handwheel 16 is rotated by hand or the hexagonal nut 17 is rotated with an electric wrench, which rotates the threaded sleeve 18, thereby pushing the stud 112 against the push plate 113, pressing the inner wall of the rubber pad 114 against the outer wall of the mold column tube 2, thereby achieving the purpose of locking the outer wall of the mold column tube 2. This prevents concrete leakage or deformation of the mold column tube 2 during pouring. After the locking structure 1 is fixed on the outer wall of the mold column tube 2, the concrete raw material is injected into the inner cavity of the mold column tube 2. At the same time, the drive motor 4 is started. The drive motor 4 drives the rotation of gear 41. Under the meshing action between gear 41 and ring gear 42, the ring gear 42 is driven to rotate. The ring gear 42 then transmits power to the shaft 45, which in turn drives the chain 47 and rubber ball 48 to rotate. One side of the rubber ball 48 strikes the inner wall at the edge of the mold column tube 2, causing the mold column tube 2 to vibrate. This vibrates the concrete in the inner cavity of the mold column tube 2, preventing hollow areas in the concrete.

[0032] Example 2

[0033] like Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a guide post 19 is movably sleeved on the top of the L-shaped guide rod 110, a support spring 111 is movably sleeved on the bottom of the outer wall of the guide post 19 and located on the right side of the L-shaped guide rod 110, the upper and lower ends of the guide post 19 are fixedly installed with the front of the first clamp 11, an adjusting handwheel 16 is fixedly installed on the top of the threaded sleeve 18, a hexagonal prism nut 17 is fixedly connected to the bottom of the inner wall of the adjusting handwheel 16, a rubber pad 114 is fixedly connected to the inner wall of the push plate 113, and the inner wall of the rubber pad 114 overlaps with the outer wall of the mold column tube 2.

[0034] In this embodiment, the rubber pad 114 increases the friction between the inner wall of the push plate 113 and the outer wall of the mold column tube 2, preventing the locking structure 1 from falling off the outer wall of the mold column tube 2. The guide post 19 and the L-shaped guide rod 110 guide both sides of the outer wall of the push plate 113, preventing the stud 112 from rotating the push plate 113 when the threaded sleeve 18 is rotated, thus affecting the pressing effect on the outer wall of the mold column tube 2.

[0035] Example 3

[0036] like Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a return spring 116 is fixedly installed on the front of the second clamp 12, a push rod 115 is fixedly installed on the left side of the return spring 116, the outer wall of the push rod 115 is movably sleeved with the front of the second clamp 12, and a roller 117 is rotatably connected to the left side of the push rod 115, and the left side of the outer wall of the roller 117 overlaps with the right side of the buckle 14.

[0037] In this embodiment, when it is necessary to disassemble the locking structure 1, the inclined pin 13 is removed from the connection between the right side of the first clamp 11 and the second clamp 12. Then, the push rod 115 is pushed by the action of the return spring 116, so that the push rod 115 pushes the roller 117, causing the buckle 14 and the locking block 15 to separate. This allows the right side connection between the first clamp 11 and the second clamp 12 to be separated, thereby facilitating the disassembly of the locking structure 1.

[0038] Example 4

[0039] like Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, one side of the rubber ball 48 overlaps with the front of the mold column tube 2, the outer wall of the gear 2 46 is rotatably connected to the front of the mold column tube 2, guide grooves 44 are provided on the upper and lower sides of the ring gear 42, steel balls 49 overlap the inner wall of the guide grooves 44, the outer wall of the steel balls 49 is rotatably connected to the front of the clamping plate 43, a hexagonal prism 410 is fixedly connected to the bottom of the gear 2 46, a guide groove post 411 is inserted into the bottom of the hexagonal prism 410, and the bottom of the guide groove post 411 is fixedly installed with the top of the bottom gear 2 46.

[0040] In this embodiment, the steel ball 49 and the guide groove 44 facilitate the transmission of the ring gear 42, reducing the wear between the outer wall of the ring gear 42 and the inner wall of the clamping plate 43. The hexagonal prism 410 and the guide groove 411 facilitate the connection between the gears 46, thereby facilitating the transmission of the gears 46 at the connection between the mold column tubes 2 and the mold column tubes 2.

[0041] The working principle of this concrete pipe pile casting mold will be explained in detail below.

[0042] like Figure 1-6As shown, firstly, place the mold column tube 2 in a suitable position, and then fit the first clamp 11 and the buckle 14 onto the appropriate position on the outer wall of the mold column tube 2. Insert one end of the buckle 14 into the right side of the first clamp 11, so that the top of the right side of the buckle 14 is engaged with the left side of the clamp block 15. Then, insert the inclined pin 13 into the left side of the buckle 14, which connects the right sides of the first clamp 11 and the second clamp 12. Then, turn the adjusting handwheel 16 by hand or turn the hexagonal nut 17 with an electric wrench, which will rotate the threaded sleeve 18, thereby pushing the stud 112 against the push plate 113, so that the inner wall of the rubber pad 114 is pressed tightly against the outer wall of the mold column tube 2. This achieves the purpose of locking the outer wall of the mold column tube 2, thereby avoiding concrete leakage or deformation of the mold column tube 2 during pouring. The rubber pad 114 increases the friction between the inner wall of the push plate 113 and the outer wall of the mold column tube 2, preventing the locking structure 1 from detaching from the outer wall of the mold column tube 2. The guide post 19 and L-shaped guide rod 110 guide both sides of the outer wall of the push plate 113, preventing the stud 112 from rotating the push plate 113 when the threaded sleeve 18 is rotated, thus affecting the clamping effect on the outer wall of the mold column tube 2. When it is necessary to disassemble the locking structure 1, the inclined pin 13 is removed from the connection between the right side of the first clamp 11 and the second clamp 12. Then, the push rod 115 is pushed by the return spring 116, which in turn pushes the roller 117, causing the buckle 14 and the locking block 15 to separate. This allows the right-side connection between the first clamp 11 and the second clamp 12 to be separated, facilitating the disassembly of the locking structure 1. After the locking structure 1 is fixed to the outer wall of the mold column tube 2, concrete material is injected into the inner cavity of the mold column tube 2. At the same time, the drive motor 4 is started. The drive motor 4 drives the gear 41 to rotate, and the meshing action between the gear 41 and the ring gear 42 drives the ring gear 42 to rotate, thereby allowing the ring gear 42 to transmit power to the shaft 45. The movement causes gear 46 to drive chain 47 and rubber ball 48 to rotate, causing one side of rubber ball 48 to strike the inner wall of the mold column tube 2 edge, causing the mold column tube 2 to vibrate. This vibrates the concrete inside the mold column tube 2, preventing the concrete from becoming hollow. The steel ball 49 and guide groove 44 facilitate the transmission of ring gear 42, reducing wear between the outer wall of ring gear 42 and the inner wall of clamping plate 43. The hexagonal prism 410 and guide groove 411 facilitate the connection between gears 46, thus facilitating the transmission of gear 46 at the connection between mold column tubes 2.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
