Description

Technical Field

[0001] This utility model belongs to the field of concrete pole production and processing, specifically, it relates to a lifting device for pole steel formwork. Background Technology

[0002] The steel formwork for utility poles is the core equipment used to manufacture concrete utility poles. It is mainly made of high-quality steel plates and features high strength, high precision, and long service life.

[0003] The prior art (publication number: CN222042401U) discloses a pole steel formwork lifting tool, which includes two guide plates distributed front and rear. A fixing block is fixedly connected to the middle between the opposite sides of the two guide plates. First steel ropes are fixedly connected to the left and right sides of the lower end face of the fixing block. Fixing clamps are installed at the lower ends of the two first steel ropes.

[0004] Existing technology uses a symmetrically movable clamp at the bottom of the device in conjunction with a fixed symmetrical clamp at the bottom of the device to lift the steel formwork of the utility pole. However, while the existing technology can lift the steel formwork of the utility pole, if an imbalance occurs during the lifting process, there is a high probability that the lifting will be unstable, posing a significant safety hazard.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A lifting device for utility pole formwork, comprising:

[0008] The base frame is rectangular. Rectangular plates are symmetrically fixed to the top of the base frame. A first motor is fixed to one side wall of the base frame, and a second motor is fixed to the side wall of the rectangular plate on the other side.

[0009] The suspension rope is fixedly connected to one side of the bottom of the base frame, and a clamp is fixedly connected to the bottom of the suspension rope;

[0010] The balancing structure is set on the wall of the base frame to adjust the balance of the base frame. The balancing structure includes an upper shaft, a balancing block, and a follower block. The upper shaft is rotatably connected between symmetrical rectangular plates at the top of the base frame. The balancing block is slidably set between the symmetrical rectangular plates. The follower block is symmetrically fixedly connected to the front and rear walls of the balancing block. The balancing block can move at the top of the base frame.

[0011] In a preferred embodiment of this utility model, the upper shaft is worm-shaped and can pass through the side wall of the balance block and be threadedly connected to the balance block. The bottom of the symmetrical follower block can contact the top of the base frame, and the second motor can drive the upper shaft to rotate.

[0012] In a preferred embodiment of this utility model, the balancing structure further includes a lower shaft and a sliding plate.

[0013] In a preferred embodiment of the present invention, the first motor can drive the lower shaft to rotate within the base frame cavity. The lower shaft is also worm-shaped, and the moving plate is rectangular. The lower shaft can pass through the side wall of the moving plate and be threadedly connected to the moving plate.

[0014] In a preferred embodiment of this utility model, each follower block is symmetrically and fixedly connected to a safety rope at its bottom, and each clamp is fixedly connected to a hook on its front and rear walls.

[0015] In a preferred embodiment of this utility model, the top end of each safety rope can be fixedly connected to the bottom of the follower block, the bottom end of each safety rope on each side can be fixedly connected to the top end of the clamp on the same side, and the length of the safety rope is greater than that of the lower shaft.

[0016] In a preferred embodiment of this utility model, the hook is hook-shaped with the opening facing upwards.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. By setting up a balancing structure with movable balancing blocks, the system can restore balance when imbalance occurs, thereby improving the safety of hoisting the steel formwork of the utility pole.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a lifting device for steel formwork of utility poles includes: a base frame 20, which is rectangular in shape, with rectangular plates symmetrically fixedly connected to the top of the base frame 20, a first motor 21 fixedly connected to one side wall of the base frame 20, and a second motor 22 fixedly connected to the side wall of the rectangular plate on the other side.

[0030] The lifting rope 23 is fixedly connected to one side of the bottom of the base frame 20. The bottom of the lifting rope 23 is fixedly connected to the clamp 24. The first motor 21 and the second motor 22 are both electrically connected to the corresponding power supply. The top of the symmetrical rectangular plate is connected to the crane boom. This is existing technology, so it will not be described in detail here.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a balancing structure is set on the wall of the base frame 20 to adjust the balance of the base frame 20. The balancing structure includes an upper shaft 32, a balancing block 33, and a follower block 34. The upper shaft 32 is rotatably connected between symmetrical rectangular plates at the top of the base frame 20. The balancing block 33 is slidably set between the symmetrical rectangular plates. The follower block 34 is symmetrically fixedly connected to the front and rear walls of the balancing block 33. The balancing block 33 can move at the top of the base frame 20.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the upper shaft 32 is worm-shaped and can pass through the side wall of the balance block 33 and be threadedly connected to the balance block 33. The bottom of the symmetrical follower block 34 can contact the top of the base frame 20. The second motor 22 can drive the upper shaft 32 to rotate. The balancing structure also includes a lower shaft 30 and a sliding plate 31. The lower shaft 30 is rotatably connected to the cavity of the base frame 20, and the sliding plate 31 is slidably connected to the cavity of the base frame 20. The bottom of the sliding plate 31 is fixedly connected with the same suspension rope 23 and clamp 24. The first motor 21 can drive the lower shaft 30 to rotate in the cavity of the base frame 20. The lower shaft 30 is also worm-shaped. The sliding plate 31 is a rectangular plate. The lower shaft 30 can pass through the side wall of the sliding plate 31 and be threadedly connected to the sliding plate 31. The bottom of each follower block 34 is symmetrically fixedly connected with a safety rope 35. The front and rear walls of each clamp 24 are fixedly connected with hooks 36.

[0033] In practical use, the entire device is first hoisted by a crane boom to a position directly above the steel formwork of the utility pole to be hoisted. Then, the power to the first motor 21 is turned on, driving the lower shaft 30 to rotate. As the lower shaft 30 rotates, it causes the moving plate 31 to move horizontally along the cavity of the base frame 20. As the moving plate 31 moves horizontally, it causes the lifting rope 23 and clamps 24 at its bottom to move synchronously. After the two clamps 24 at the bottom of the base frame 20 are aligned with the length of the utility pole formwork, the clamps 24 can be clamped onto the wall of the utility pole formwork. When the utility pole formwork is fixed by the clamps 24, The steel mold can be fixed again by wrapping ropes around the walls of the symmetrical hooks 36 on each side and then wrapping them around the steel mold walls. At this time, the base frame 20 can be moved by the crane boom and then the steel mold can be lifted. If the steel mold is unbalanced when it is lifted, the upper shaft 32 can be driven to rotate by turning on the power of the second motor 22. When the upper shaft 32 rotates, it will drive the balance block 33 to slide along the symmetrical rectangular plates. As the balance block 33 moves, it will drive the follower block 34 to move synchronously. When the balance block 33 moves in the direction of tilting, the balance of the device can be adjusted.

[0034] In summary, by setting up a balancing structure and using movable balancing blocks 33, the system can restore balance when imbalance occurs by moving the balancing blocks 33, thereby improving the safety of hoisting the steel formwork of the utility pole.

[0035] like Figure 3 and Figure 4 As shown, the top end of each safety rope 35 can be fixedly connected to the bottom of the follower block 34, and the bottom end of each safety rope 35 can be fixedly connected to the top end of the clamp 24 on the same side. The length of the safety rope 35 is greater than that of the lower shaft 30, and the hook 36 is hook-shaped with the opening of the hook 36 facing upward.

[0036] In practical use, if the hoisting rope 23 breaks when hoisting the steel formwork, the bottom of the safety rope 35 will connect with the top of the clamp 24.

[0037] In summary, by setting up the safety rope 35, the clamp 24 can be lifted in place of the lifting rope 23 in the event of an accidental breakage, thereby effectively reducing the cost and danger in the event of an accident. The hook 36 can further prevent the steel mold from falling when the clamp 24 is fixing the steel mold.

[0038] Working principle: First, the entire device is hoisted to a position directly above the steel formwork of the utility pole to be hoisted using a crane boom. Then, the power to the first motor 21 is turned on, driving the lower shaft 30 to rotate. As the lower shaft 30 rotates, it causes the moving plate 31 to move horizontally along the cavity of the base frame 20. This horizontal movement of the moving plate 31 causes the lifting rope 23 and clamps 24 at its bottom to move synchronously. Once the two clamps 24 at the bottom of the base frame 20 are aligned with the length of the utility pole formwork, the clamps 24 are clamped onto the wall of the utility pole formwork. While the utility pole formwork is fixed by the clamps 24, it also... The steel mold can be fixed again by wrapping ropes around the walls of the symmetrical hooks 36 on each side and then around the steel mold walls. At this time, the base frame 20 can be moved by the crane boom and then the steel mold can be lifted. If the steel mold becomes unbalanced when it is lifted, the upper shaft 32 can be driven to rotate by turning on the power of the second motor 22. When the upper shaft 32 rotates, it will drive the balance block 33 to slide along the symmetrical rectangular plates. As the balance block 33 moves, it will drive the follower block 34 to move synchronously. The balance of the device can be adjusted when the balance block 33 moves in the direction of tilting.
