Description

Technical Field

[0001] This utility model relates to the technical field of lifting devices for cement pole production, specifically a lifting device for cement pole production. Background Technology

[0002] Cement poles are long, tapered structures made of reinforced concrete (commonly 8-15 meters in length and weighing several tons), primarily used for supporting power and communication lines. Whether after production or before use, they typically require alignment, lifting, and transfer. Their large taper and difficult-to-control center of gravity place special demands on lifting. Existing lifting devices mostly use wire ropes combined with mechanical grippers or support plates to fix the poles, which generally have poor clamping stability. The clamping devices cannot dynamically adapt to changes in the pole's taper, making them prone to swaying and overturning during lifting. Furthermore, they generally lack real-time safety features such as torque limiting and fall prevention.

[0003] The patent document with publication number "CN 222475918 U" mentions: "During the lifting of cement poles, slippage is likely to occur, causing the cement poles to fall and creating danger and accidents. It is also inconvenient to clamp and fix them according to the model and thickness of the cement poles, lacking adaptability. Using clamping components to clamp the cement poles according to their model provides better adaptability." This device improves its adaptability to different types of cement by using different models of clamping components to clamp the cement column. However, because the device requires the use of different models of clamping components, the replacement of the clamping components is relatively troublesome. Moreover, the device requires manual tightening of the clamping points, which is time-consuming. Therefore, the adaptability and operation difficulty of the device do not meet the requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting device for cement pole production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lifting device for cement pole production, comprising a lifting device, a platform fixedly connected to one side of the lifting device, and a hook fixedly connected to the lower side of the platform. A stable support mechanism and an adaptive centering and bottom-supporting mechanism are provided on the lower side of the hook, wherein the adaptive centering and bottom-supporting mechanism is provided on the lower side of the stable support mechanism.

[0006] The stabilizing support mechanism includes a hanging platform, which is attached to the lower end of the hook. A hanging plate is fixedly connected to the lower end of the hanging platform. Sleeves are fixedly connected to the upper surfaces of both ends of the hanging plate. Centering columns are fixedly connected to the upper surfaces of the sleeves. Nuts are threaded onto the outer walls of the centering columns. Rotary sleeves are rotatably connected to the upper sides of the nuts. Turntables are fixedly connected to both sides of the hook. Connecting sleeves are rotatably connected inside the turntables. Cables are fixedly connected between the connecting sleeves and the rotating sleeves.

[0007] Preferably, the centering post is configured with a threaded structure.

[0008] Preferably, the length of the cable is set between the top of the centering column and the connecting sleeve.

[0009] Preferably, the adaptive centering and bottom-supporting mechanism includes multiple motors and a hanging box. Each motor is fixedly connected inside the sleeve, and each hanging box is fixedly connected to the lower surfaces of both ends of the hanging plate. Each motor output end is fixedly connected to a stud, which is rotatably connected inside the hanging box. Each hanging box contains a limit block and a positioning platform, which are located below the limit block. Each stud has a threaded sliding top connected to its outer wall, which is slidably connected between the limit platform and the limit block. Each sliding top has a rotatably connected top wheel at its lower end. Each hanging box contains multiple curved platforms, which are located on both sides of the sliding top. Each curved platform has a rotatably connected rotating frame at its lower end. Multiple grippers are rotatably connected to the adjacent side of the rotating frame. A traction spring is fixedly connected between the upper end of the rotating frame and the lower end of the adjacent curved platform.

[0010] Preferably, each of the rotating frames has an inclined surface on its upper side, and one end of each traction spring is fixedly connected to the inclined surface.

[0011] Preferably, each of the sliding tops is fixedly connected to a trapezoidal structure in the middle, with the shorter sides of the trapezoidal structures all pointing downwards.

[0012] Preferably, the upper ends of the curved platforms are all tangent to the outer wall of the trapezoidal structure, and the long sides of the trapezoidal structure are all slidably connected to the inner wall of the hanging box.

[0013] Compared with the prior art, this utility model provides a lifting device for cement pole production, which has the following advantages:

[0014] 1. The adaptive centering support mechanism is used to clamp and limit the cement column. This mechanism clamps the cement column with multiple independent self-centering clamps, so that cement columns of different models can be clamped. This avoids the trouble caused by replacing clamping components and splicing components, and improves clamping efficiency and adaptability.

[0015] 2. The stabilizing support mechanism provides stable support for the adaptive centering bottom support mechanism. This mechanism adjusts the length of the traction arm by adjusting the length of the cable, thereby addressing the instability of the cement pole caused by the difference in gravity at both ends of the suspended platform, thus improving safety.

[0025] Example 1:

[0026] Please see Figure 1-5 This utility model provides a technical solution: a lifting device for cement pole production, including a lifting device 1, a lifting platform 2 fixedly connected to one side of the lifting device 1 and a hook 3 fixedly connected to the lower side of the lifting platform 2, a stable support mechanism 4 and an adaptive centering and bottom supporting mechanism 5 are provided on the lower side of the hook 3, and the adaptive centering and bottom supporting mechanism 5 is provided on the lower side of the stable support mechanism 4.

[0027] This mechanism is used to provide eccentric adjustment for the cement column. It enables the cement column to maintain balance by adding additional traction force. The stable support mechanism 4 includes a hanging platform 401, which is hung on the lower end of the hook 3. A hanging plate 402 is fixedly connected to the lower end of the hanging platform 401. A sleeve 403 is fixedly connected to the upper surface of both ends of the hanging plate 402. A centering column 404 is fixedly connected to the upper surface of the sleeve 403. A nut 405 is threadedly connected to the outer wall of the centering column 404. A rotating sleeve 406 is rotatably connected to the upper side of the nut 405. A turntable 407 is fixedly connected to both sides of the hook 3. A connecting sleeve 408 is rotatably connected inside the turntable 407. A cable 409 is fixedly connected between the connecting sleeve 408 and the rotating sleeve 406.

[0028] Furthermore, the centering post 404 is configured with a threaded structure.

[0029] Furthermore, the length of the cable 409 is set between the top of the centering column 404 and the connecting sleeve 408.

[0030] Example 2:

[0031] This mechanism is used for adaptive clamping of cement columns. It solves the problem of time-consuming and labor-intensive replacement of different types of clamps in traditional devices through a self-centering clamping method. (Please refer to...) Figure 1-5Furthermore, in conjunction with Embodiment 1, the adaptive centering and bottom-supporting mechanism 5 includes multiple motors 501 and a lifting box 502. All motors 501 are fixedly connected inside the sleeve 403, and all lifting boxes 502 are fixedly connected to the lower surfaces of both ends of the lifting plate 402. Each output end of the motor 501 is fixedly connected to a stud 503, which is rotatably connected inside the lifting box 502. Each lifting box 502 has a limit block 504 and a positioning platform 505 fixedly connected inside it. The positioning platform 505 is located below the limit block 504. The studs 503... The outer wall is threaded with a sliding top 506, which is slidably connected between the limiting platform and the limiting block 504. The lower end of the sliding top 506 is rotatably connected with a top wheel 507. The inside of the hanging box 502 is rotatably connected with multiple curved platforms 508. The curved platforms 508 are all located on both sides of the sliding top 506. The lower end of the curved platform 508 is rotatably connected with a rotating frame 509. The side of the rotating frame 509 that is close to each other is rotatably connected with multiple grippers 510. The upper end of the rotating frame 509 and the lower end of the adjacent curved platform 508 are fixedly connected with traction springs 511.

[0032] Furthermore, each of the upper sides of the rotating frame 509 is provided with an inclined surface, and one end of each traction spring 511 is fixedly connected to the inclined surface.

[0033] Furthermore, each of the sliding roofs 506 has a trapezoidal structure fixedly connected to its center, with the shorter sides of the trapezoidal structures all pointing downwards.

[0034] Furthermore, the upper end of the curved platform 508 is tangent to the outer wall of the trapezoidal structure, and the long side of the trapezoidal structure is slidably connected to the inner wall of the hanging box 502.

[0035] In actual operation, when this device is used, the user lowers the hook 3 using the lifting device 1, then places the gripper 510 on the outside of the cement column. The user can then start the motor 501. When the motor 501 outputs power, it drives the stud 503 to rotate. The stud 503, through threaded engagement with the sliding top 506, causes the sliding top 506 to move. After the sliding top 506 moves, it drives the top wheel 507 to move, simultaneously causing the trapezoidal structure to abut against the top of the curved platform 508, forcing the curved platform 508 to rotate. Because the rotating frame 509 is lifted by the spring and the gripper 510 rotates at a small angle, the curved platform 508 rotates... During the process, the clamping jaws 510 and the top wheel 507 work together to form a triangular stable support, allowing the cement column to be clamped stably at multiple points. At the same time, since the clamping jaws 510 are evenly distributed at both ends of the hanging plate 402 and are individually controlled by the motor 501, the cement column can still be clamped even if there is an incline. After the cement column is clamped, the user can lift it using the lifting device 1. If the user finds that the hanging plate 402 is tilted, the user can tighten the nut 405 on the unbalanced side to make the rotating sleeve 406 move down along the centering column 404 simultaneously, so that the cable 409 provides additional support force to keep the hanging plate 402 balanced, making the device more stable.
