Description

Technical Field

[0001] The utility model belongs to the technical field of wind power hybrid tower installation, and more specifically, relates to a tower top tooling of a wind power hybrid tower. Background Art

[0002] In the field of wind power hybrid towers, the traditional method for the hoisting and bundling of prestressed steel strands is to install a rotating crane on the top of the tower through a large lifting device, and use the rotating arm and power traction device of the rotating crane to pull the steel strands at the bottom of the tower to the top and carry out the top bundling. However, installing the rotating crane on the top of the tower requires the use of large lifting equipment (generally, the tower piece's lifting equipment can be used), and after the hoisting and bundling is completed, it is also necessary to use a large crane to rotate the top surface to the ground. This hoisting and bundling operation method is highly dependent on large lifting equipment, so there are certain limitations in terms of efficiency.

[0003] In order to improve operational efficiency, reduce dependence on large lifting equipment, and take operational safety into consideration.

[0004] According to the needs of the site, a transmission device composed of a frame structure was developed here. This device adopts an assembled structure and can be disassembled into lightweight tooling components, which can be carried to the top by a simple traction rope or manually. By hoisting two sets of pulleys and connecting the traction rope to the ground height, the crane can be placed at the bottom of the tower, reducing the part of high-altitude operations, which improves the safety and speed of construction.

[0023] The following, with reference to the accompanying drawings, describes the embodiments and further explains the specific implementation methods of the utility model, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the utility model.

[0024] A tower top tooling for a wind power hybrid tower comprises a steel cable, a tower 1, a support 2 and a fixing part. The tower 1 is in the shape of a hollow cylinder. A first cable hole 3 is provided at an equal angle on a circumferential surface close to the inner wall of the tower 1. A warning bolt 4 is provided at an equal angle on a circumferential surface close to the outer wall of the tower 1. A saddle-shaped connecting block 5 is provided at the bottom of the support 2. The support 2 is fixedly connected to the tower 1 via the connecting block 5. The fixing part is arranged at the center of the tower 1 and is fixedly connected to the tower 1. A lifting pulley 6 is provided at the center of the fixing part.

[0025] The fixed part includes a plurality of saddle-shaped connecting blocks 5 and a steel rope 7 connected to a lifting pulley 6 . The connecting blocks 5 are fixedly arranged on the circumferential surface of the tower 1 . One end of the steel rope is connected to the connecting block 5 , and the other end of the steel rope is connected to the lifting pulley 6 .

[0026] The support 2 is in the shape of a quadrangular pyramid and includes a connecting rod 10, a connecting block 5, a support column 9, a mounting block and a lifting pulley 6. The bottom of the support 2 is an isosceles trapezoid composed of the connecting rod 10. Support columns 9 are fixedly installed on the four corners of the isosceles trapezoid. Each support column 9 is tilted and the tops of the four support columns 9 are gathered at one point. The mounting blocks are set on the tops of the four support columns, and the lifting pulley 6 is installed at the bottom of the mounting blocks.

[0027] Through the above settings: During the construction process, the structure was split into 4 parts to facilitate installation and position adjustment on the top of the tower. The whole structure is composed of 8 rods, which are fixed by welding and bolts respectively; forming two triangular diagonal braces. The triangular diagonal braces provide strong stability for the structure, without the risk of deviation. The triangular diagonal braces save materials. The design replaces the original heaviest installation rod with an inclined structure and steel sheet bolt connection, which further reduces the overall weight.

[0028] The support 2 is in the shape of a triangular prism and includes a connecting rod 10, a connecting block, a support column 9, a mounting rod 8 and a lifting pulley 6. The bottom of the support 2 is an isosceles trapezoid formed by the connecting rod 10, and support columns 9 are fixedly installed on the four corners of the isosceles trapezoid. Each support column 9 is tilted and the two support columns on each connecting block form a triangle with the connecting block. The mounting rod 8 connects the tops of the two triangles, and the lifting pulley 6 is installed on the mounting rod 8.

[0029] It needs to be further explained that: the back of the support 2 can also be connected diagonally with steel wire ropes to more effectively reduce the lateral deformation of the frame structure, that is, reinforcing ribs are added to the support 2 to ensure the stability of the support.

[0030] The support 2 includes a connecting block, a support column 9, a mounting rod 8 and a lifting pulley 6. A plurality of connecting blocks 5 are provided at the bottom of the support 2. The connecting blocks 5 are distributed on the circumferential surface of the tower. A supporting column 9 is fixedly installed on each connecting block 5, two of which are vertically arranged. The tops of the two vertically arranged support columns 9 are connected by the mounting rod 8. Except for the vertically arranged support columns 9, the other ends of all the support columns 9 away from the connecting blocks are sleeved on the mounting rod 8, and the lifting pulley 6 is installed on the mounting rod 8.

[0031] Through the above arrangement: in actual operation, the tooling may have a tendency to topple due to the lateral load, and this solution further utilizes the support balance of the inclined support column 9.

[0032] The connection block 5 is provided with a threaded hole, and the connection block 5 and the tower 1 are detachably connected by bolts.

[0033] Through the above arrangement: the connection block 5 is responsible for fixing the position and the fulcrum by means of the bolts on the tower top itself, and the position where the hole needs to be opened can be flexibly determined.

[0034] Working principle and method

[0035] Installation: The rotating lifting fixture is carried manually or placed on the top surface of the tower with the help of a crane. After forming a stable fixture, the fixed pulley is hoisted.

[0036] Work: Lower one end of the steel cable from the first cable hole to the bottom of the tower and connect it to the steel strand bundle to be pulled. Lower the other end along the fixed pulley to the winch at the bottom of the tower. Start the winch to pull the bundle of steel strands to the top of the tower for subsequent work such as anchor replacement, installation, and bundle insertion at the bottom of the tower.

[0037] Adjustment: replace the tooling and install it at the top of the tower, lower the steel cable from the other first cable threading hole 5, pull the steel strand, repeat the above operation, and pull and thread other steel strand bundles until all the steel strand bundles of this tower are threaded. The tooling on the top of the tower can be disassembled and removed, and subsequent work such as steel strand tensioning can be carried out.

[0038] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
