Description

Technical Field

[0001] This utility model relates to the field of pipe jacking wire winding technology, and in particular to a pipe surface wire winding device for increasing the prestress of JPCCP pipe jacking. Background Technology

[0002] JPCCP, short for Prestressed Concrete Cylinder Pipe, is a composite pipe consisting of an inner concrete lining, an embedded thin steel cylinder, spirally wound prestressed steel wires, and an outer protective mortar layer. The prestressed steel wires give it high resistance to internal and external pressure and excellent durability. The concrete and mortar layers protect the steel cylinder from corrosion, resulting in a long design life.

[0003] Existing technology, patent CN222115512U, discloses a pipe surface winding device for increasing the prestress of JPCCP jacking pipes, relating to the field of winding device technology. This pipe surface winding device for increasing the prestress of JPCCP jacking pipes includes a winding platform, a lifting plate on one side of the upper surface of the winding platform, a mounting plate slidably mounted inside the lifting plate, a rotating fixing mechanism rotatably connected to one side of the mounting plate, and a load-bearing plate slidably mounted on the other side of the upper surface of the winding platform. The other end of the rotating fixing mechanism is located within the load-bearing plate. This invention eliminates the need to lift the jacking pipe upwards by lowering its height, then moving the jacking pipe horizontally onto the winding platform, allowing it to pass through the rotating fixing mechanism. Adjusting the height of the rotating fixing mechanism moves the jacking pipe away from the ground, and moving the load-bearing plate to one side of the rotating fixing mechanism for support. This allows for quick fixing of the jacking pipe within the rotating fixing mechanism, reducing safety hazards and improving winding efficiency.

[0004] The device requires a secondary push of the jacking pipe when winding steel wire around the jacking pipe. The jacking pipe itself is heavy, making the secondary push difficult. Furthermore, the vibration and impact of pushing the jacking pipe can easily damage the device. The device uses a wire bundle to wind the steel wire, but the position of the wire bundle is fixed, and the wire can only be wound on a portion of the pipe surface, which has certain limitations. Therefore, a pipe surface wire winding device that increases the prestress of the JPCCP jacking pipe is needed to meet the application requirements. Utility Model Content

[0005] The purpose of this invention is to provide a pipe surface winding device for increasing the prestress of JPCCP jacking pipe, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe surface winding device for increasing the prestress of JPCCP jacking pipe, comprising a support platform, a base mounted on the top of the support platform, a rotating groove formed on the base, a drive shaft rotatably mounted in the rotating groove, an electric push rod mounted on the drive shaft, a contact block mounted on the output end of the electric push rod, an electric trolley mounted on the support platform, a support plate mounted on the electric trolley, an unwinding wheel rotatably mounted in the support plate, an unwinding motor mounted on the support plate, the unwinding wheel mounted on the output end of the unwinding motor, and a support base mounted at the bottom of the support platform.

[0007] Preferably, a first drive motor housing is adjustablely provided on the support platform, a first drive motor is installed inside the first drive motor housing, and the drive shaft is installed at the output end of the first drive motor.

[0008] Preferably, a slide rail is installed on the support platform, and a sliding sleeve is installed at the bottom of the housing of the first drive motor, the sliding sleeve being slidably fitted onto the slide rail.

[0009] Preferably, a rack is installed on the sliding sleeve, a gear is meshed on the rack, a second drive motor housing is adjustablely provided on the support platform, a second drive motor is installed inside the second drive motor housing, and the gear is installed at the output end of the second drive motor.

[0010] Preferably, a protective shell is installed on the support platform, the protective shell covers the rack and the gear, and the protective shell has an opening and a strip-shaped opening.

[0011] Preferably, a guide plate is installed on the support platform, and a guide hole is formed on the guide plate.

[0012] Preferably, the electric trolley is equipped with a guide block, which is slidably installed in the guide hole, and an anti-detachment block is installed at the end of the guide block.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the rotation of the electric push rod and contact block drives the rotation of the JPCCP jacking pipe. The steel wire to be wound is pre-wound onto the JPCCP jacking pipe from the unwinding wheel. The rotation of the JPCCP jacking pipe winds the steel wire, and the movement of the electric trolley drives the unwinding wheel to move. The movement of the unwinding wheel ensures that the steel wire is evenly wound onto the outer surface of the JPCCP jacking pipe, resulting in a large area of ​​wire winding around the pipe surface, good winding effect, and uniform winding.

[0015] In this invention, the movement of the rack towards the JPCCP jacking tube causes the sliding sleeve, the housing of the first drive motor, the first drive motor, and the drive shaft to move towards the base, inserting the drive shaft into the base and thus into the interior of the JPCCP jacking tube. The extension of the electric push rod causes the contact block to press against the inner wall of the JPCCP jacking tube, providing a supporting action and facilitating the rotation of the JPCCP jacking tube to wind the steel wire.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] like Figure 1-4As shown, this embodiment provides a pipe surface winding device for increasing the prestress of JPCCP jacking pipe, including a support platform 1. The device is characterized by: a base 2 mounted on the top of the support platform 1; a rotating groove 3 on the base 2; a drive shaft 4 rotatably mounted within the rotating groove 3; an electric push rod 5 mounted on the drive shaft 4; a contact block 6 mounted at the output end of the electric push rod 5; an electric trolley 7 mounted on the support platform 1; a support plate 8 mounted on the electric trolley 7; a unwinding wheel 9 rotatably mounted within the support plate 8; an unwinding motor 10 mounted on the support plate 8; and the unwinding wheel 9 mounted at the output end of the unwinding motor 10. A support 11 is mounted at the bottom of the support platform 1. The JPCCP jacking pipe is hoisted into the rotating groove 3. When the drive shaft 4 moves towards the base 2, it enters the interior of the JPCCP jacking pipe. The extension of the electric push rod 5 causes the contact block 6 to abut against the inner wall of the JPCCP jacking pipe, thus providing a contacting effect. The rotation of drive shaft 4 drives electric push rod 5 and contact block 6 to rotate, which in turn drives the JPCCP jacking pipe to rotate. The steel wire to be wound is pre-wound onto the JPCCP jacking pipe from the unwinding wheel 9. The rotation of the JPCCP jacking pipe winds the steel wire. The movement of electric trolley 7 drives the unwinding wheel 9 to move, allowing the steel wire to be evenly wound onto the outer surface of the JPCCP jacking pipe. This results in a large area of ​​wire winding around the pipe surface, good winding effect, and uniform winding.

[0024] To drive the drive shaft 4, electric push rod 5, and contact block 6 into or out of the JPCCP jacking pipe, a first drive motor housing 12 is adjustablely mounted on the support platform 1. A first drive motor 13 is installed inside the first drive motor housing 12, and the drive shaft 4 is mounted on the output end of the first drive motor 13. A slide rail 14 is mounted on the support platform 1, and a sliding sleeve 15 is mounted at the bottom of the first drive motor housing 12. The sliding sleeve 15 is slidably fitted onto the slide rail 14, and a rack 16 is mounted on the sliding sleeve 15. A gear 17 is meshed on the rack 16. A second drive motor housing 18 is adjustablely mounted on the support platform 1, and a second drive motor housing 18 is installed inside the second drive motor housing 18. Motor 19 and gear 17 are installed at the output end of drive motor 19. When drive motor 19 is started, the rotation of drive motor 19 will drive gear 17 to rotate. The rotation of gear 17 will drive rack 16 to move towards the JPCCP top tube. The movement of rack 16 towards the JPCCP top tube will drive sliding sleeve 15, drive motor housing 12, drive motor 13, and drive shaft 4 to move towards the base 2, and insert drive shaft 4 into base 2, thereby allowing drive shaft 4 to enter the interior of JPCCP top tube.

[0025] Reversing the second drive motor 19 will cause the gear 17 to reverse, and the reverse rotation of the gear 17 will cause the rack 16 to move away from the JPCCP top tube. The movement of the rack 16 away from the JPCCP top tube will cause the sliding sleeve 15, the housing 12 of the first drive motor, the first drive motor 13, and the drive shaft 4 to move away from the base 2, and cause the drive shaft 4 to be pulled out from the base 2, thereby causing the drive shaft 4 to leave the interior of the JPCCP top tube.

[0026] To protect the rack 16 and gear 17, a protective shell 20 is installed on the support platform 1. The protective shell 20 covers the rack 16 and gear 17, and has an opening 21 and a strip-shaped opening 22. The protective shell 20 covers the rack 16 and gear 17, thus protecting them, while the opening 21 and the strip-shaped opening 22 do not affect the movement of the moving parts.

[0027] To guide the movement of the electric trolley 7, a guide plate 23 is installed on the support platform 1. The guide plate 23 has a guide hole 24. A guide block 25 is installed on the electric trolley 7. The guide block 25 is slidably installed in the guide hole 24. An anti-detachment block 26 is installed at the end of the guide block 25. The sliding of the guide block 25 in the guide hole 24 can guide the movement of the electric trolley 7, so that the electric trolley 7 can only move along the guide plate 23. The anti-detachment block 26 can prevent the guide block 25 from falling out of the guide hole 24.

[0028] Working Principle: During use, the JPCCP jacking pipe is suspended within the rotating trough 3. Then, the second drive motor 19 is activated. The rotation of the second drive motor 19 drives the gear 17, which in turn moves the rack 16 closer to the JPCCP jacking pipe. This movement of the rack 16 in turn moves the sliding sleeve 15, the housing 12 of the first drive motor, the first drive motor 13, and the drive shaft 4 closer to the base 2, causing the drive shaft 4 to insert into the base 2 and thus into the JPCCP jacking pipe. The extension of the electric push rod 5 causes the contact block 6 to abut against the inner wall of the JPCCP jacking pipe, providing a contacting effect. Then, the first drive motor 13 is activated. The rotation of the first drive motor 13 drives the drive shaft 4, which in turn rotates the electric push rod 5 and the contact block 6, ultimately causing the JPCCP jacking pipe to rotate. The steel wire to be wound is pre-wound onto the JPCCP jacking pipe inside the unwinding wheel 9. The rotation of the JPCCP jacking pipe winds the steel wire. The movement of the electric trolley 7 moves the unwinding wheel 9, allowing the steel wire to be evenly wound onto the outer surface of the JPCCP jacking pipe. This results in a large area of ​​wire winding, good winding effect, and uniform winding. After winding, the sliding sleeve 15 retracts, causing the contact block 6 to no longer press against the inner surface of the JPCCP jacking pipe. The reverse rotation of the second drive motor 19 drives the gear 17 to reverse, which in turn moves the rack 16 away from the JPCCP jacking pipe. This movement of the rack 16 away from the JPCCP jacking pipe causes the sliding sleeve 15, the housing 12 of the first drive motor, the first drive motor 13, and the drive shaft 4 to move away from the base 2, pulling the drive shaft 4 out of the base 2. This allows the drive shaft 4 to leave the JPCCP jacking pipe, and the JPCCP jacking pipe can then be lifted out of the device. The operation is convenient and easy to use.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
