Technical Field

[0001] The utility model relates to the field of tower barrel production, in particular to a hoisting and fixing clamp for wind power tower barrel production. Background Technique

[0002] The wind power tower barrel is an important part of the wind power generating set and is usually made of concrete or steel. Its main function is to support and fix the upper structure of the wind power generating set, including the impeller and the generator. The design of the tower barrel takes into account the bearing capacity, stability and wind resistance performance to ensure the safe operation of the wind power generating set under various weather conditions. The height of the tower barrel is usually determined according to the wind resource and technical economy. The higher the tower barrel, the higher the wind energy utilization efficiency.

[0003] In the production of the tower barrel, its diameter is between 3 meters and 5 meters, and the length of each section of the tower barrel is about 5 meters to 10 meters.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0026] First embodiment:

[0027] Referring to Figures 1-3 As shown, the present utility model provides a production hoisting and fixing fixture for a wind power generation tower barrel, including end brackets 1. The number of end brackets 1 is two, and they are respectively used for being arranged on both sides of the length of the tower barrel. Two side rods 2 are detachably installed between the two end brackets 1. The two side rods 2 are respectively close to both sides of the tower barrel. The two end brackets 1 and the two side rods 2 form a frame structure for supporting the bottom of the tower barrel. A side suspension rod 4 is movably connected to the outer side of each side rod 2. A lifting ring is provided at the high end of the side suspension rod 4. When the device is in use, the end brackets 1 are placed at both ends of the length of the tower barrel, and the two side rods 2 are installed on the left and right sides of the tower barrel, so that the distance between the two side rods 2 is less than the diameter of the tower barrel. The lifting ring at the high end of the side suspension rod 4 is hoisted by a crane, so as to lift the side rod 2, and the side rod 2 can be used to support the bottom of the tower barrel, improving the hoisting effect of the tower barrel.

[0028] A plurality of first rubber rings 201 in contact with the outer wall of the tower barrel are provided on the outer side of the side rod 2, and the first rubber rings 201 are used to achieve buffering.

[0029] Preferably, the bottom end of the side suspension rod 4 is rotatably connected to the side rod 2. There are two side suspension rods 4 on each side rod 2, and the two side suspension rods 4 are symmetrically arranged along the length center line of the side rod 2. The side suspension rod 4 has a folded structure, and a second rubber ring 401 in contact with the tower barrel is provided on its outer side. By using the contact between the second rubber ring 401 and the outer wall of the tower barrel, the second rubber ring 401 can form contact with the end bracket 1, which can achieve support and buffer protection. Moreover, the side suspension rods 4 on the two side rods 2 correspond to each other, so that it is convenient to hoist the tower barrel by hoisting the lifting rings at the high ends of the side suspension rods 4.

[0030] The second embodiment is different from the first embodiment in the following features:

[0031] Threaded sections are provided at both ends of the side rod 2, and nut seats 202 for fastening the side rod 2 are provided on the outer sides of the threaded sections. The end bracket 1 has a folded structure, and inclined grooves 101 extending downward are provided at both ends thereof. The end of the side rod 2 is in clearance fit with the inclined grooves 101. When connecting the side rod 2, the two end brackets 1 are made to correspond to both sides of the length of the tower barrel, the threaded sections at both ends of the side rod 2 are respectively inserted into the inclined grooves 101, and the nut seats 202 are screwed on the outer sides of the end brackets 1 to form a limit for the side rod 2. Further, two nut seats 202 are provided at the end of the side rod 2, and the two nut seats 202 are respectively screwed on both sides of the end bracket 1 to fix the side rod 2.

[0032] The third embodiment is different from the first embodiment in the following features:

[0033] A buffer frame 3 for auxiliary support of the tower barrel is provided on the end bracket 1. When lifting and lowering the tower barrel, the buffer frame 3 is used to achieve the buffering effect. Specifically, in the structure of the buffer frame 3, the buffer frame 3 includes a guide sleeve 301, the guide sleeve 301 is connected to the bottom of the end bracket 1, an inner rod 302 is slidably connected to its bottom, a bottom plate 304 is provided at the bottom of the inner rod 302, and a thrust spring 303 is provided between the end bracket 1 and the bottom plate 304. By sliding the inner rod 302 inside the guide sleeve 301, the position of the bottom plate 304 can be adjusted, and the bottom plate 304 can be supported and buffered in cooperation with the thrust spring 303. When placing the tower barrel downward, the elasticity of the thrust spring 303 is used to achieve buffering, and the bottom plate 304 can also assist the end bracket 1 to be stably placed on the ground.

[0034] The top of the guide sleeve 301 penetrates through the end bracket 1 and is threadedly connected to the end bracket 1. By using the threaded connection between the guide sleeve 301 and the end bracket 1, the height of the guide sleeve 301 can be adjusted, thereby adjusting the height of the bottom plate 304, which is suitable for the hoisting settings of tower barrels with different diameters.

[0035] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily conceive of changes or substitutions, which should all be covered within the protection scope of the present utility model.
