Description

Technical Field

[0001] This utility model relates to the field of iron tower hoisting, specifically a hoisting device for heavy-duty iron tower components. Background Technology

[0002] The tower component hoisting device consists of a lifting frame, cables, and hooks. Hooks are typically fitted onto the parts of the tower component to be hoisted, serving to fix and position them. One end of the cable is connected to the lifting frame, and the other end is connected to a lifting ring on a fixing ring. When the hoisting device is activated, the lifting frame applies an upward tension to the fixing ring through the cables, thereby lifting the crossbeams on the tower. The lifting frame is the core of the hoisting device's operation; it controls the length and tension of the cables to achieve the hoisting and positioning of the tower components. Some lifting frames may be equipped with electric or manual winching mechanisms for raising and lowering the cables.

[0003] In the existing technology, when lifting the crossbeam of a steel tower, the cables on the lifting device slide, and both ends of the cables need to be fixed to the crossbeam of the steel tower. With the development of the market, the cables can be slid on the lifting device to adjust the distance between the cables, which is convenient for lifting different types of steel tower crossbeams.

[0004] However, the aforementioned method of sliding the buckle on the lifting device can cause the device to sway during hoisting, leading to the buckle sliding and making it difficult to secure it to the inner wall of the device. Furthermore, the upward pulling force of the lifting device and the downward force of gravity on the tower beam can cause compression, which can easily deform the tower beam when it is too heavy, resulting in damage to the buckle. Moreover, when handling different types of tower beams, the buckle needs to be continuously slid on the lifting device, which can cause wear and tear over time, leading to the buckle getting stuck when sliding on the device. Therefore, a hoisting device for heavy-duty tower components needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device for heavy-duty components of iron towers, so as to solve the problems mentioned in the background art.

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Example 1 Please see Figures 1-5This utility model provides a technical solution: a hoisting device for heavy-duty components of iron towers, including a hoisting frame 1, with stop blocks 2 rotatably connected to both ends of the hoisting frame 1. Holes are opened on the surface of the stop blocks 2, and rotating rods 12 are inserted into the holes. Baffles 2 are fixed to both ends of the hoisting frame 1, and both ends of the rotating rods 12 are fixed to the baffles 13. A screw 19 is mounted on the surface of the stop blocks 2. During hoisting, the screw 19 passes through the stop blocks 2 and is threadedly connected to the hoisting frame 1. First, the screw 19 is screwed until it is screwed out of the holes in the stop blocks 2. Then, the stop blocks 2 are folded over, and the stop blocks 2 rotate with the rotating rods 12, thereby opening one end of the bottom groove of the hoisting frame 1. A slider 3 is inserted into the bottom groove of the hoisting frame 1 until one side of the stop blocks 2 is in contact with the hoisting frame 1. Finally, the screw 19 is screwed to fix the stop blocks 2 and the hoisting frame 1 together.

[0016] Example 2 Based on Embodiment 1, a slider 3 is slidably provided at the bottom of the lifting frame 1, and a groove 14 is provided at the bottom of the lifting frame 1. The groove 14 is a "T"-shaped square groove, and the slider 3 is a "T"-shaped square block. The slider 3 is inserted into the groove 14 through one end of the lifting frame 1 and slides on the groove 14. The shape of the slider 3 matches the shape of the groove 14. The slider 3 is inserted into the groove at the bottom of the lifting frame 1 and can slide on the groove.

[0017] Example 3 Based on Embodiment 2, a pull buckle 4 is fixed to the bottom of the slider 3, and buffer plates 5 are installed on the bottom surfaces of both sides of the slider 3. A pusher frame 6 is fixed to the bottom of the buffer plate 5, and a pusher plate 7 is fixed to the bottom of the pusher frame 6. The pusher frame 6 is a "T"-shaped square rod. Multiple slots 15 are opened on the top surface of the bracket 11, and the width of the slots 15 is the same as the width of the pusher frame 6. An oil storage cavity 16 is opened inside the bracket 11, and the pusher plate 7 is located inside the oil storage cavity 16. The pusher frame 6 penetrates the top surface of the bracket 11 and is integrally formed with the pusher plate 7. When lifting, the lifting frame 1 will move upward. When a pulling force is applied, the crossbeam on the tower will exert gravity downwards, causing the slider 3 to press downwards and contact the buffer plate 5. This, in turn, causes the pusher frame 6 and the pusher plate 7 to press downwards within the oil storage chamber 16. The lubricating oil inside the oil storage chamber 16 will be pressurized and transported into the rubber tube 9, and output from the top surface of the pusher frame 6. At the same time, the pusher frame 6 will press downwards and contact the rubber pad 10. After hoisting, the pusher frame 6 will return to its original shape due to its own elasticity, thus keeping the top surface of the pusher frame 6 and the top surface of the support 11 at the same level.

[0018] Example 4 Based on Embodiment 3, rubber rings 8 are fixedly installed on both sides of the push plate 7, and a rubber tube 9 is inserted and fixedly connected to the top surface of the push frame 6. The rubber rings 8 are in contact with the inner wall of the oil storage cavity 16. The rubber tube 9 is a "T"-shaped round tube, and the internal pipe of the rubber tube 9 passes through the push frame 6 and the push plate 7. The internal pipe of the rubber tube 9 is connected to the top of the oil storage cavity 16 and the push frame 6 respectively. One end of the rubber tube 9 is fixedly connected to the push plate 7. Rubber pads 10 are fixed on the bottom surfaces of both sides of the push frame 6. A lifting device is also included. Supports 11 are fixed on both sides of the bottom of the frame 1. Rubber pads 10 are fixedly connected to the top surface of the support 11. An oil inlet 17 is opened on the top surface of the support 11. A seal 18 is inserted into the oil inlet 17. The seal 18 is fixed to the support 11 by a screw 20. The screw 20 is screwed until it is unscrewed from the surface of the seal 18. Then the seal 18 is pulled out and the lubricating oil is poured into the oil inlet 17. The lubricating oil will enter the oil storage chamber 16 along with the oil inlet 17.

[0019] In use, first screw 19 is screwed until it comes out of the hole in stop 2. Then stop 2 is folded over, and it will rotate with the rotating rod 12, thus opening one end of the bottom slide groove of the lifting frame 1. Then slide block 3 is inserted into the slide groove at the bottom of the lifting frame 1. Slide block 3 can slide on the slide groove. Then multiple cables are passed through the buckles 4 on the slide block 3 to fix the crossbeam on the tower. Both ends of the crossbeam on the tower are fixed to the cables. Screw 20 is screwed until it comes out of the surface of the seal 18. Then the seal 18 is pulled out, and lubricating oil is poured into the oil inlet 17. The lubricating oil will enter the oil storage chamber 16 through the oil inlet 17. Then stop block 19 is screwed out. 2. Rotate until one side of the stop block 2 is in contact with the lifting frame 1. Then tighten the screw 19 to fix the stop block 2 and the lifting frame 1 together. Then lift. The lifting frame 1 will apply an upward pulling force, and the crossbeam on the iron tower will apply a downward gravity, so that the slider 3 will be squeezed downward and contact the buffer plate 5. This will drive the push frame 6 and the push plate 7 to be squeezed downward in the oil storage chamber 16. The lubricating oil inside the oil storage chamber 16 will be pressurized and transported into the rubber tube 9 and output from the top surface of the push frame 6. At the same time, the push frame 6 will contact the rubber pad 10 when it is squeezed downward. After the lifting is completed, the push frame 6 will return to its original shape due to its own elasticity, so that the top surface of the push frame 6 and the top surface of the support 11 are at the same level.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
