Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and in particular to an auxiliary device for uncoiling coiled steel bars. Background Technology

[0002] Spiral ribbed steel bars, also known as spiral ribbed steel bars or threaded steel coils, are a type of steel reinforcement material with spiral ribs, typically supplied in coil form. They are primarily used in concrete structures to provide enhanced tensile strength and seismic resistance. Uncoiling aids are devices specifically designed to handle the process of straightening spiral ribbed steel bars from a coiled state.

[0003] Currently, existing coiled steel bars are placed on a coiled steel bar placement rack for uncoiling and straightening before being uncoiled and straightened. However, placing the coiled steel bars on the placement rack may easily cause wear and tear, and the placement rack structure may be unstable or the steel bar coil may not be securely fixed, which may lead to tipping accidents during operation.

[0004] Therefore, how to provide an auxiliary device for uncoiling coiled steel bars is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide an auxiliary device for uncoiling coiled steel bars. By setting up adjustment components and support components, it can support coiled steel bars of different diameters and rotate them, which can facilitate the subsequent uncoiling and straightening of the coiled steel bars, thereby solving the problems mentioned in the background art.

[0006] An auxiliary device for uncoiling coiled steel bars according to an embodiment of the present invention includes a fixed frame and a fixed connecting shaft. A rotating motor is fixedly connected to the top left side of the inner wall of the fixed frame. A first double-threaded rod is fixedly connected to the output end of the rotating motor. Movable blocks are threadedly connected to both sides of the outer wall of the first double-threaded rod. A sliding block is fixedly connected to the right side of each movable block. A worm is fixedly connected to the middle of the outer wall of the first double-threaded rod. A worm wheel is meshed with the outer wall of the worm. A second double-threaded rod is fixedly connected inside the worm wheel. Movable blocks are threadedly connected to both sides of the outer wall of the second double-threaded rod. A sliding block is fixedly connected to the right side of each movable block. The sliding block is fixedly connected to a support plate.

[0007] As a preferred embodiment of this utility model: a threaded column is fixedly connected to the right side of the fixed connecting shaft, a connecting ring plate is threadedly connected to the outer wall of the threaded column, and a rotating snap-fit ​​component is provided inside the connecting ring plate.

[0008] As a further preferred embodiment of this utility model: a movable support frame is fixedly connected to the outer wall of the connecting ring plate, and a sliding groove is provided on the outer wall of the movable support frame, and the sliding groove is slidably connected to a sliding block.

[0009] As a further preferred embodiment of this utility model: the outer wall of the movable support frame is provided with a snap-fit ​​groove, and the outer wall of the fixed connecting shaft is fixedly connected with a number of telescopic connecting blocks.

[0010] As a further preferred embodiment of this utility model: a support plate is fixedly connected between the sides of the telescopic connecting blocks away from the fixed connecting shaft, and coiled steel bars are provided between the outer walls of the support plate.

[0011] As a further preferred embodiment of this utility model: a drive motor is fixedly connected to the left side of the fixing frame, a connecting plate is fixedly connected to the output end of the drive motor, and a connecting ring plate is fixedly connected to the right side of the connecting plate.

[0012] As a further preferred embodiment of this utility model: a support frame is fixedly connected to the outer wall of the connecting ring plate, and a sliding groove is provided on the outer wall of the support frame, and the sliding groove is slidably connected to the sliding block.

[0013] As a further preferred embodiment of this utility model: a movable plate is hinged to the right side of the fixed frame, and a rotating locking member is rotatably connected to the middle of the right side of the movable plate.

[0014] The beneficial effects of this utility model are:

[0015] First, flip the movable plate upwards. Then, use a tool to rotate the movable support frame, causing the connecting ring plate to rotate around the threaded column. Remove the connecting ring plate and the movable support frame. Next, pull out the pin on the outer wall of the telescopic connecting block. Then, start the rotating motor according to the diameter of the coiled steel bar to drive the first double-ended threaded rod to rotate. The rotation of the first double-ended threaded rod drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The rotation of the worm wheel drives the second double-ended threaded rod to rotate. The rotation of the first and second double-ended threaded rods respectively drives the movable blocks and movable block 2 on both sides of the outer wall to move to opposite sides. The movement of the movable block and movable block two can drive the support plate to move to the opposite side via the sliding block, thereby changing the distance between the two support plates. Using hoisting tools, the coiled steel bar is moved to the outer wall of multiple support plates, ensuring that the coiled steel bar can be clamped when it moves to the outer wall of the support plate. Then, the movable support frame is rotated in the opposite direction to make the threaded engagement between the connecting ring plate and the threaded column. Next, the movable plate is lowered, and then the rotating clamping piece is rotated so that its left end rotates into the inside of the connecting ring plate. Finally, by starting the drive motor, the coiled steel bar is rotated through the connecting plate at the output end of the drive motor, which facilitates the subsequent uncoiling and straightening processing of the coiled steel bar.

A movable plate 5 is hinged to the right side of the fixed frame 1. A rotating snap-fit ​​part 21 is rotatably connected to the middle of the right side of the movable plate 5.

[0027] The first double-threaded rod 12 is driven to rotate by starting the rotating motor 11. While rotating, the first double-threaded rod 12 can also drive the worm 17 in the middle of its outer wall. The rotation of the worm 17 drives the worm wheel 16 to rotate, and the rotation of the worm wheel 16 drives the second double-threaded rod 18 to rotate. The rotation of the first double-threaded rod 12 and the second double-threaded rod 18 can respectively drive the movable blocks 14 and the second movable block 15 on both sides of the outer wall to move. Thus, the spacing of the support plate 8 can be adjusted by the movable blocks 14 and the second movable block 15 through the sliding block 13.

[0028] refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, a threaded column 22 is fixedly connected to the right side of the fixed connecting shaft 10.

Next, start the rotating motor 11 according to the diameter of the coiled steel bar to drive the first double-ended threaded rod 12 to rotate. The rotation of the first double-ended threaded rod 12 can drive the worm gear 17 to rotate. The rotation of the worm gear 17 drives the worm wheel 16 to rotate. The rotation of the worm wheel 16 drives the second double-ended threaded rod 18 to rotate. The rotation of the first double-ended threaded rod 12 and the second double-ended threaded rod 18 can respectively drive the movable blocks 14 and the second movable block 15 on both sides of the outer wall to rotate.

Using hoisting tools, the coiled steel bar is moved to the outer wall of multiple support plates 8 to ensure that the coiled steel bar can be clamped when it moves to the outer wall of the support plate 8. Then, the movable support frame 7 is rotated in the opposite direction to make the threaded engagement between the connecting ring plate 20 and the threaded column 22. Then, the movable plate 5 is lowered, and then the rotating clamping piece 21 is rotated so that its left end rotates into the inside of the connecting ring plate 20. Finally, by starting the drive motor 2, the coiled steel bar is rotated through the connecting plate 19 at the output end of the drive motor 2, which facilitates the subsequent uncoiling and straightening processing of the coiled steel bar.
