AI Technical Summary
During cable installation, it is difficult to keep the collection bucket precisely in the center of the cable laying frame, which leads to accelerated wear of the cable laying rollers.
By setting up positioning components, including a fixed plate, bearing, screw, guide rod, slider, support shaft, limit block and extension rod, the movement of the extension rod drives the slider to slide on the screw, ensuring that the storage bucket is located in the center of the outer surface of the pay-off roller and avoiding positional deviation.
This effectively avoids increased friction on the pay-off roller caused by misalignment of the storage bin, thus extending the service life of the pay-off roller.

[0029] As shown in Figures 1-5 The present application provides a cable paying-off device, comprising:
[0030] The paying-off assembly comprises a paying-off frame 11.
[0031] The positioning assembly comprises a fixing plate 21, a bearing 22, a screw rod 23, a guide rod 24, a sliding block 25, a supporting shaft 26, a limiting block 27, an extension rod 28 and a clamping groove 29. The fixing plate 21 is fixedly connected to the inner side of the lower end of the paying-off frame 11. The bearing 22 is rotatably connected to the inner central position of the fixing plate 21. The screw rod 23 is fixedly connected to the inner part of the bearing 22. The guide rod 24 is fixedly connected to the inner side of the lower end of the fixing plate 21. The sliding block 25 is threadedly connected to the outer surfaces of the two ends of the screw rod 23. The supporting shaft 26 is rotatably connected to the inner part of the sliding block 25. The limiting block 27 is fixedly connected to the outer surface of the central part of the supporting shaft 26. The extension rod 28 is rotatably connected to the outer surface of the supporting shaft 26. The clamping groove 29 is formed in the inner central position of the lower end of the extension rod 28.
[0032] The fixing plate 21 is used for supporting the bearing 22. The bearing 22 can rotate the screw rod 23 in the inner part thereof. The screw rod 23 is used for supporting and moving the sliding block 25. The guide rod 24 is used for limiting and guiding the sliding block 25. The sliding block 25 is used for supporting the supporting shaft 26. The supporting shaft 26 is used for supporting the limiting block 27 and the extension rod 28. The extension rod 28 is used for positioning the storage barrel 14. The clamping groove 29 is used for placing the limiting block 27.
[0033] The paying-off assembly further comprises a supporting plate 12, a paying-off roller 13 and a storage barrel 14. The supporting plate 12 is arranged on the outer surface of the upper end of the paying-off frame 11. The paying-off roller 13 is rotatably connected to the upper end of the supporting plate 12. The storage barrel 14 is sleeved on the outer surface of the paying-off roller 13.
[0034] The paying-off frame 11 is used for supporting the supporting plate 12. The supporting plate 12 is used for placing the paying-off roller 13 and enabling the paying-off roller 13 to rotate on the upper end of the supporting plate 12. The paying-off roller 13 is used for supporting and rotating the storage barrel 14. The storage barrel 14 is used for storing the cable.
[0035] The outer surface of the screw rod 23 is provided with opposite screw thread structures at both ends, and the lower end of the sliding block 25 is sleeved on the outer surface of the guide rod 24.
[0036] When the screw rod 23 rotates, the screw rod 23 drives the sliding block 25 to rotate and move through the screw thread structure, and the sliding block 25 only moves horizontally without rotating under the limiting of the guide rod 24.
[0037] The extension rod 28 is sleeved on the outer surface of the upper end of the sliding block 25, and the clamping groove 29 is provided opposite to the limiting block 27.
[0038] The limiting block 27 can slide in the extension rod 28, and when the limiting block 27 is located in the clamping groove 29, the extension rod 28 cannot rotate, and when the limiting block 27 is not located in the clamping groove 29, the extension rod 28 can rotate.
[0039] Working principle: before the cable is unwound, the supporting shaft 26 is pushed by the operator to drive the limiting block 27 to slide in the extension rod 28, and when the limiting block 27 slides to the outside of the clamping groove 29, the clamping groove 29 does not limit the limiting block 27, the extension rod 28 is rotated and placed in a vertical upward state, and then a pushing force is applied to the extension rod 28 to move it to the center, so that the extension rod 28 moves to the center, at this time, the extension rod 28 moves to drive the sliding block 25 to move horizontally, the sliding block 25 moves to drive the screw rod 23 to rotate in the bearing 22, the screw rod 23 rotates to drive the sliding block 25 to rotate and move horizontally, and the sliding block 25 only moves horizontally without rotating under the limiting of the guide rod 24, so that the two groups of extension rods 28 move synchronously to the center by the same distance, the outer side of the storage barrel 14 is positioned by the extension rod 28, so that the storage barrel 14 is located on the outer surface of the unwinding roller 13, and when the unwinding process is carried out, the extension rod 28 is rotated to be located on the upper end of the screw rod 23 and below the storage barrel 14, so that the cable on the storage barrel 14 is blocked to avoid the cable rubbing on the outer surface of the screw rod 23 and the ground.
[0040] Please refer to Figure 6 The embodiment further comprises:
[0041] The limiting assembly comprises a supporting block 31, a movable column 32, a handle 33, a limiting plate 34, an extension spring 35, a stopper 36, a through hole 37 and a gear 38. The supporting block 31 is fixedly connected to the lower end of the outer side of the supporting plate 12. The movable column 32 is slidingly connected to the inner central part of the supporting block 31. The handle 33 is fixedly connected to the bottom end of the movable column 32. The limiting plate 34 is fixedly connected to the top end of the movable column 32. The extension spring 35 is fixedly connected to the central position of the upper end of the supporting block 31. The stopper 36 is fixedly connected to the outer surface of the upper end of the movable column 32. The through hole 37 is arranged in the central position of the supporting block 31. The gear 38 is fixedly connected to the outer surface of one end of the pay-off roller 13.
[0042] The supporting block 31 is used for guiding the movable column 32. The movable column 32 is used for supporting the handle 33, the limiting plate 34 and the stopper 36. The handle 33 is used for the operator to hold. The limiting plate 34 is used for blocking the gear 38. The extension spring 35 is used for driving the limiting plate 34 to reset. The stopper 36 is used for limiting the movable column 32. The through hole 37 is used for the stopper 36 to move. The gear 38 is used for being engaged with the limiting plate 34.
[0043] The limiting plate 34 and the stopper 36 are in parallel state. The through hole 37 is arranged relative to the stopper 36.
[0044] When the stopper 36 is located below the through hole 37, the limiting plate 34 is located below the gear 38. When the stopper 36 is located above the through hole 37, the limiting plate 34 is located in the tooth groove of the gear 38.
[0045] The end of the extension spring 35, which is away from the supporting block 31, is fixedly connected to the bottom end position of the limiting plate 34. The limiting plate 34 is located below the gear 38.
[0046] When the stopper 36 is located below the through hole 37, the limiting plate 34 drives the extension spring 35 to be compressed to generate elastic force.
[0047] Working principle: when the wire is needed to be released, the operator applies a rotating force to the handle 33, so that the handle 33 drives the stop block 36 to rotate to the position corresponding to the through hole 37 through the movable column 32, and then applies a downward pulling force to the handle 33, so that the handle 33 drives the movable column 32 to move downward, at this time, the stop block 36 penetrates through the through hole 37 and moves downward, and the limiting plate 34 moves out of the inside of the gear groove of the gear 38, so that the limiting plate 34 does not block the gear 38, so that the wire release roller 13 can normally rotate to release the storage barrel 14, when the wire release is needed to be stopped, in order to avoid the storage barrel 14 to continuously rotate and release the wire in the inertia state, the above steps are operated in reverse, until the limiting plate 34 moves upward to the inside of the gear groove of the gear 38, so that the limiting plate 34 blocks the gear 38, and the supporting block 31 blocks the stop block 36, so that the stop block 36 cannot move downward along the through hole 37, that is, the limiting plate 34 cannot move downward and can continuously limit the gear 38, so that the wire release roller 13 cannot continuously drive the storage barrel 14 to rotate and release the wire through the limiting of the gear 38.
[0048] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
