Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a tower lifting auxiliary device. Background Technology

[0002] Lifting devices are mechanical equipment used to lift, lower, and move heavy objects horizontally. They are indispensable tools in modern industry, construction, logistics and transportation, greatly expanding human capacity to handle heavy objects. Lifting devices replace human labor with mechanical means, realizing the mechanization, automation and efficiency of heavy object handling, and are one of the important indicators of a country's level of industrial modernization.

[0003] Towers are typically large, heavy cylindrical structures, weighing tens or even hundreds of tons. During hoisting, they face the challenge of deformation. Directly using steel wire ropes for hoisting can cause localized dents or permanent deformation of the tower shell due to the immense pressure. Deformed cylinders lead to a decrease in load-bearing capacity. Under pressure, even a small localized dent can significantly reduce the overall stability of the cylinder, making it more prone to buckling. Deformation alters the ideal stress distribution of the structure, leading to stress concentration and thus greatly reducing the fatigue life and ultimate load-bearing capacity of the structure. To address this, this utility model proposes a tower hoisting auxiliary device. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the tendency of existing hoisting methods to cause deformation of the tower body, this utility model proposes an auxiliary device for tower hoisting.

The inner wall of the second sleeve is slidably connected to the side of the first sleeve. One side of the pad abuts against the inner wall of the cylinder. A support plate is fixedly connected to one side of the pad. Several support plates and pads are provided. Each of the several support plates is fixedly connected to one side of the second sleeve with a connecting block. A support rod is hinged to the inner wall of the connecting block.

[0006] Preferably, a fixing plate is fixedly connected to the bottom of the first sleeve, and a screw is threadedly connected to the inner wall of the first sleeve, with the side of the screw slidably connected to the inner wall of the second sleeve.

[0007] Preferably, a limiting ring is fixedly connected to the side of the screw, and two sets of the limiting ring are provided, with both sets of the limiting ring abutting against the second sleeve.

[0008] Preferably, the fixed plate has guide grooves, and there are several guide grooves. The bottom of the support plate is fixedly connected to a slider, and there are several sliders. The inner walls of the guide grooves are slidably connected to the sides of the sliders.

[0009] Preferably, the side of the cylinder is fixedly connected with a clamping plate, and two sets of clamping plates are symmetrically arranged.

[0010] Preferably, the inner wall of the clamp is movably connected with a screw, and the surface of the screw is threaded with a nut.

[0011] Preferably, two sets of lifting rings are fixedly connected to the clamp.

[0012] The advantages of this utility model are: This invention, by setting up a support structure, can form a stable support inside the cylinder, reducing the possibility of cylinder deformation caused by hoisting. By setting up a pad, it can reduce the possibility of internal deformation of the cylinder caused by the opening of the support structure. The support structure can be unfolded and closed. During use, by changing the vertical position of the second sleeve and the support plate, the relative angle of the support rod hinged by the connecting block can be changed.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a tower lifting auxiliary device. (Refer to...) Figure 1 , Figure 2 and Figure 3 A tower lifting auxiliary device includes a cylinder 1, a first sleeve 2 is provided inside the cylinder 1, and a support structure 3 is provided on the side of the first sleeve 2; The support structure 3 includes a second sleeve 301 and a pad 302. The inner wall of the second sleeve 301 is slidably connected to the side of the first sleeve 2. One side of the pad 302 abuts against the inner wall of the cylinder 1. A support plate 303 is fixedly connected to one side of the pad 302. Several support plates 303 and pads 302 are provided. Each of the several support plates 303 and one side of the second sleeve 301 is fixedly connected to a connecting block 304. A support rod 305 is hinged to the inner wall of the connecting block 304. By setting the pad 302, the possibility of deformation inside the cylinder 1 caused by the opening of the support structure 3 can be reduced. The support structure 3 can be opened and closed. During use, by changing the upper and lower positions of the second sleeve 301 and the support plate 303, the relative angle of the support rod 305 hinged to the two through the connecting block 304 can be changed. By changing the angle of the support rod 305, the support plate 303 can be driven to open or close radially towards the second sleeve 301.

[0018] Reference Figure 2 The bottom of the first sleeve 2 is fixedly connected to a fixed plate 4, and the inner wall of the first sleeve 2 is threadedly connected to a screw 5. The side of the screw 5 is slidably connected to the inner wall of the second sleeve 301. By rotating the screw 5 inside the first sleeve 2, the second sleeve 301, which is slidably connected to the screw 5, can be driven to move up and down.

[0019] Reference Figure 2A limiting ring 6 is fixedly connected to the side of the screw 5. There are two sets of limiting rings 6. Both sets of limiting rings 6 abut against the second sleeve 301. By setting the limiting rings 6, the screw 5 and the second sleeve 301 can always maintain a fixed relative height. At the same time, the second sleeve 301 is kept from rotating so as not to affect the rotation of the screw 5. The bottom surface of one set of limiting rings 6 abuts against the top surface of the second sleeve 301, and the top surface of the other set of limiting rings 6 abuts against the inner wall of the second sleeve 301.

[0020] Reference Figure 2 and Figure 5 The fixed plate 4 has guide grooves 7, and there are several guide grooves 7. The bottom of the support plate 303 is fixedly connected to a slider 8, and there are several sliders 8. The inner walls of the guide grooves 7 are slidably connected to the sides of the sliders 8. By setting the guide grooves 7 on the fixed plate 4, they are used to cooperate with the sliders 8 at the bottom of the support plate 303 to keep the height of the support plate 303 relative to the fixed plate 4. When the second sleeve 301 moves up and down, the support plate 303 moves horizontally and radially relative to the second sleeve 301.

[0021] Reference Figure 1 and Figure 4 The side of the cylinder 1 is fixedly connected with a clamping plate 9. Two sets of clamping plates 9 are symmetrically arranged. By setting two sets of clamping plates 9, the cylinder 1 can be clamped, which facilitates the hoisting work. The surfaces of the two sets of clamping plates 9 that are in contact with the cylinder 1 are covered with rubber to increase friction.

[0022] Reference Figure 1 and Figure 4 The inner wall of the clamping plate 9 is movably connected with a screw 10, and the surface of the screw 10 is threaded with a nut 11. By setting the screw 10, it passes through the two sets of clamping plates 9 and cooperates with the nut 11 to clamp the clamping plate 9 to the cylinder 1.

[0023] Reference Figure 1 and Figure 4 A lifting ring 12 is fixedly connected to the clamp plate 9. There are two sets of lifting rings 12. The lifting rings 12 are used to cooperate with the lifting equipment to carry out the lifting work of the cylinder 1. The two sets of lifting rings 12 are used to maintain the stability of the lifting process.

[0024] Working principle: First, the support structure 3 is inserted into the cylinder 1. Rotating the screw 5 inside the first sleeve 2 causes the second sleeve 301, which is slidably connected to the screw 5, to move downwards outside the first sleeve 2. This changes the relative angle of the support rod 305. Through the guide groove 7 on the fixed plate 4 and the slider 8 at the bottom of the support plate 303, the height of the support plate 303 remains constant relative to the fixed plate 4. At this time, the support rod 305 pushes the support plate 303 to expand horizontally and radially relative to the second sleeve 301 until the pad 3 on the support plate 303... 02. Abut against the inner wall of the cylinder 1, assemble the two sets of clamping plates 9 onto the outer side of the cylinder 1, and then clamp the clamping plates 9 onto the cylinder 1 using screws 10 and nuts 11. Lower the lifting hook of the lifting equipment to hook the lifting ring 12, and finally start the lifting equipment to lift the cylinder 1. After lifting, first release the fixing of the outer clamping plates 9 of the cylinder 1, and then rotate the screw 5 in the opposite direction to drive the second sleeve 301, which in turn drives the support plate 303 to radially close, and pull the support structure 3 away from the cylinder 1 for recovery. Repeat the above operation to continue the lifting work.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
