Description

Technical Field

[0001] This utility model relates to the technical field of prestressed concrete, specifically to an auxiliary device for the production of prestressed concrete pipe piles. Background Technology

[0002] Prestressed concrete is a type of concrete component mainly used in building construction and bridge engineering. To prevent premature cracking in reinforced concrete structures, it makes full use of high-strength steel bars and high-strength concrete. Before the concrete structure or component bears the service load, external force is applied to reduce the tensile stress generated in the component, or even to put the concrete component in a state of compressive stress. When producing concrete pipe piles, the following processing sequence is followed: wire drawing, cage weaving, concrete placement, mold closing, tensioning, centrifugal molding, steam protection, and demolding.

[0003] Utility model patent CN220008248U discloses an auxiliary device for the production of prestressed concrete pipe piles, belonging to the technical field of prestressed concrete. It addresses the problem in existing technologies where, during concrete pouring, some slender pipe piles are cast. These pipe piles have small molds, and the pouring concrete exerts a significant impact on the molds, potentially causing deformation and resulting in the finished concrete pipe piles not meeting size requirements, leading to waste, reduced production progress, and material waste. The device includes an installation plate, the top of which is fixed... A pipe pile mold is fixedly provided, with a base plate on its outer wall. The top of the base plate has an installation opening that fits onto the outside of the pipe pile mold.

[0025] 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.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] An auxiliary device for producing prestressed concrete pipe piles includes: a base plate 1; an auxiliary box 2 fixedly connected to the top of the base plate 1; a pipe pile mold body 3 mounted on the top of the auxiliary box 2; eight auxiliary rods 4 evenly arranged on the outer side of the pipe pile mold body 3; a movable block 5 mounted on the bottom of each auxiliary rod 4; each movable block 5 slidably connected to the auxiliary box 2; and a matching travel groove 6 opened near each movable block 5 in the auxiliary box 2; a self-locking mechanism 7 for controlling the synchronous movement of the auxiliary rods 4 inside the auxiliary box 2; and a disassembly and assembly mechanism 8 for replacing each movable block 5. The user places the pipe pile mold body 3 on the auxiliary box 2, and then controls the eight movable blocks 5 to move simultaneously towards the pipe pile mold body 3 within the travel groove 6 inside the auxiliary box 2 via the self-locking mechanism 7. The movement of the movable blocks 5 simultaneously drives the auxiliary rods 4, thereby supporting the pipe pile mold body 3 through the cooperation of the eight auxiliary rods 4.

[0028] like Figures 1 to 4 As shown, the self-locking mechanism 7 includes: a first rotating shaft 9 is disposed inside the auxiliary box 2, both ends of the first rotating shaft 9 are rotatably connected to the auxiliary box 2, a circular plate 10 is fixedly connected to the outer surface of the first rotating shaft 9, eight arc-shaped grooves 11 are evenly opened inside the circular plate 10, and a matching cylindrical pin 12 is disposed inside each arc-shaped groove 11, and the cylindrical pins 12 are fixedly connected to the moving block 5 respectively; a worm gear 13 is disposed at the bottom of the circular plate 10, the worm gear 13 is fixed to the outer surface of the first rotating shaft 9, a worm 14 is meshed on one side of the worm gear 13, a second rotating shaft 15 is fixedly connected inside the worm 14, one end of the second rotating shaft 15 is rotatably connected to the auxiliary box 2, and the other end of the second rotating shaft 15 passes through the auxiliary box 2 and extends to the adjusting knob 16, the adjusting knob... The knob 16 is fixedly connected to the second rotating shaft 15. When the user rotates the adjustment knob 16, the adjustment knob 16 drives the second rotating shaft 15 to rotate. While the second rotating shaft 15 rotates, it drives the worm gear 14. The worm gear 14 drives the worm wheel 13 to rotate. While the worm wheel 13 rotates, it drives the circular plate 10. While the circular plate 10 rotates, it pushes the cylindrical pin 12 through the arc groove 11. The cylindrical pin 12 drives the moving blocks 5, so that the eight moving blocks 5 move simultaneously inside the auxiliary box 2 towards the pipe pile mold body 3. While the moving blocks 5 move, they drive the auxiliary rod 4, so that the auxiliary rod 4 fits against the outside of the pipe pile mold body 3, thereby quickly supporting the pipe pile mold body 3 of different diameters and preventing the pipe pile mold body 3 from deforming when concrete is poured.

[0029] like Figure 4 As shown, the outer surface of the adjustment knob 16 is provided with a silicone sleeve 17 with a groove on the surface. The silicone sleeve 17 is fixedly connected to the adjustment knob 16, which not only improves the roughness of the outer surface of the adjustment knob 16, but also improves the comfort of the user's hand when in contact with the adjustment knob 16, making it convenient for the user to apply force to the adjustment knob 16.

[0030] like Figure 5 and Figure 6 As shown, the disassembly and assembly mechanism 8 includes: a structural plate 18 fixedly connected to the top of each movable block 5; a T-shaped limiting strip 19 fixedly connected to the side of each structural plate 18 near the auxiliary rod 4; and a matching mounting groove 20 provided on each auxiliary rod 4 near the T-shaped limiting strip 19; an internal threaded sleeve 21 fixedly connected to the side of each structural plate 18 away from the auxiliary rod 4; a disassembly and assembly knob 22 provided at the end of each internal threaded sleeve 21 away from the structural plate 18; a screw 23 fixedly connected to the side of each disassembly and assembly knob 22 near the internal threaded sleeve 21; and the end of each screw 23 away from the disassembly and assembly knob 22 passing through the internal threaded sleeve 21, the structural plate 18, and the T-shaped limiting strip 19 and extending into the interior of the auxiliary rod 4; and a matching slot 24 provided on the auxiliary rod 4 near the screw 23; the screw 23 is respectively connected to the internal threaded sleeve 21, the structural plate 18, and the T-shaped limiting strip 19. The plate 18 and the T-shaped limiting strip 19 are threaded together. When the auxiliary rod 4 is worn or deformed after long-term use, the user can rotate the disassembly knob 22 in the reverse direction. The disassembly knob 22 drives the screw 23, causing the screw 23 to separate from the slot 24 inside the auxiliary rod 4. Finally, pull the auxiliary rod 4 upward to separate the auxiliary rod 4 from the T-shaped limiting strip 19, so that the auxiliary rod 4 can be replaced. Then, align the mounting slot 20 on the replaced auxiliary rod 4 with the T-shaped limiting strip 19, and apply pressure to the auxiliary rod 4 so that the auxiliary rod 4 fits on the surface of the T-shaped limiting strip 19. Finally, rotate the disassembly knob 22 in the forward direction. The disassembly knob 22 drives the screw 23, causing one end of the screw 23 to enter the slot 24 inside the auxiliary rod 4, so that the auxiliary rod 4 can be fixed to the outer surface of the T-shaped limiting strip 19.

[0031] like Figure 3 As shown, limit grooves 25 are provided on both sides of the movable block 5, and limit strips 26 are fixedly connected to the auxiliary box 2 near the limit grooves 25. The movable block 5 is slidably connected to the limit strips 26 through the limit grooves 25, which can limit the movable block 5 and make the movable block 5 slide flexibly inside the auxiliary box 2.

[0032] like Figure 2 and Figure 6 As shown, rubber damping pads 27 are provided between the auxiliary rod 4 and the pipe pile mold body 3. The rubber damping pads 27 are fixedly connected to the auxiliary rod 4. The auxiliary rod 4 drives the rubber damping pads 27. When the rubber damping pads 27 come into contact with the pipe pile mold body 3, the rubber damping pads 27 deform with the curvature of the surface of the pipe pile mold body 3, which increases the contact area between the device and the pipe pile mold body 3, thereby improving the stability of the auxiliary rod 4 supporting the pipe pile mold body 3.

[0033] like Figure 6As shown, mounting holes 28 are provided at the four corners of the bottom of the base plate 1. Mounting bolts 29 are provided at the top of the mounting holes 28. The bottom ends of the mounting bolts 29 penetrate the mounting holes 28 and extend to the outside of the mounting holes 28, which facilitates the user to install the device and improves the stability of the device installation.

[0034] Working principle: The user places the pipe pile mold body 3 on the auxiliary box 2, and then rotates the adjustment knob 16. The adjustment knob 16 drives the second rotating shaft 15 to rotate. The rotation of the second rotating shaft 15 drives the worm gear 14, which in turn drives the worm wheel 13 to rotate. The rotation of the worm wheel 13 drives the circular plate 10, which in turn pushes the cylindrical pin 12 through the arc groove 11. The cylindrical pin 12 drives the moving blocks 5, so that the eight moving blocks 5 move simultaneously inside the auxiliary box 2 towards the pipe pile mold body 3. The movement of the moving blocks 5 drives the auxiliary rod 4, which in turn causes the rubber damping pad 27 to fit. On the outside of the pipe pile mold body 3, it can quickly support pipe pile mold bodies 3 of different diameters, preventing deformation of the pipe pile mold body 3 during concrete pouring. It can quickly support pipe pile molds of different diameters, preventing deformation during concrete pouring, simplifying the operation process, improving work efficiency, and solving the problem that existing prestressed concrete pipe pile production auxiliary devices have a complex operation process and low work efficiency because the curvature of the arc plate is not adjustable when supporting pipe pile molds of different diameters.

[0035] When the auxiliary rod 4 wears or deforms after prolonged use, the user can rotate the disassembly knob 22 in the reverse direction. The disassembly knob 22 drives the screw 23, causing the screw 23 to separate from the slot 24 inside the auxiliary rod 4. Finally, pull the auxiliary rod 4 upward to separate it from the T-shaped limiting strip 19, allowing the auxiliary rod 4 to be replaced. Then, align the mounting slot 20 on the replaced auxiliary rod 4 with the T-shaped limiting strip 19, and apply pressure to the auxiliary rod 4 so that it fits onto the surface of the T-shaped limiting strip 19. Finally, rotate the disassembly knob 22 in the forward direction. The disassembly knob 22 drives the screw 23, causing one end of the screw 23 to enter the slot 24 inside the auxiliary rod 4, thus fixing the auxiliary rod 4 to the outer surface of the T-shaped limiting strip 19. This facilitates the replacement of the auxiliary rod 4 and prevents wear or deformation after long-term use, improving the stability of the device's support for the pipe pile mold.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
