Description

Technical Field

[0001] The utility model relates to the technical field of wind power hybrid towers, in particular to a wind power generation hybrid tower pipe segment assembly mechanism. Background Art

[0002] A prefabricated wind turbine hybrid tower is usually composed of a lower concrete cylinder and an upper steel cylinder, and the concrete cylinder is connected to the steel cylinder through a connector cylinder; some of the concrete cylinders are cast in place, but due to on-site casting, especially in winter, the concrete has poor fluidity and it takes a very long time to complete the project; in order to improve efficiency, the concrete cylinder can also be spliced ​​in sections and pieces. Some of the existing wind turbine hybrid tower segment assembly mechanisms use adjacent splicing sections when connecting, installing one piece at a time, and connecting them piece by piece until a ring is formed. Since the early splicing sections are not accurately aligned, the end of the splicing section does not fit well with the first installed splicing section, and a great deal of manpower and time are required to make adjustments to complete the installation. Utility Model Content

[0003] 1. Technical Problems Solved

[0004] The technical problem to be solved by the utility model is that the connection alignment accuracy of the end parts installed piece by piece is low.

[0005] 2. Technical Solution

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a wind power generation hybrid tower segment assembly mechanism, including a plurality of splicing sections, the splicing sections cooperate with each other to form an annular structure, adjacent splicing sections are overlapped together, and a plurality of connecting parts are evenly connected between adjacent splicing sections, the connecting parts include a first hinge seat buried in one side of the splicing section, a first threaded rod is hingedly provided on the first hinge seat, a second hinge seat is buried in the adjacent splicing section, a second threaded rod is hingedly provided on the second hinge seat, the second threaded rod and the first threaded rod have opposite threads, the second threaded rod and the first threaded rod are connected together by a threaded connection with a threaded cylinder, and the splicing sections on different horizontal planes are limited and clamped together.

[0007] Furthermore, an inner overlapping portion is connected to one end of the splicing segment, and an outer overlapping portion is connected to the other end of the splicing segment. The outer overlapping portion cooperates with the inner overlapping portion. The coordinated arrangement of the inner overlapping portion and the outer overlapping portion facilitates increasing the contact area between adjacent splicing segments on the same horizontal plane, and also facilitates mutual limitation of adjacent splicing segments after connection.

[0008] Furthermore, the adjacent splicing segments that are not in the same horizontal plane are staggered so that one splicing segment is connected to six splicing segments at the same time, thereby facilitating improving the connection strength between the longitudinal splicing segments.

[0009] Furthermore, a limiting groove is provided at the top end of the lower splicing section, and the limiting grooves are arranged in an array evenly distributed with the annular structure as the axis. A limiting column is provided in the limiting groove, and a receiving groove is relatively connected to the bottom end of the top splicing section, and the other end of the limiting column extends into the receiving groove. The limiting column is first placed in the receiving groove, and when the receiving groove is opposite to the limiting groove, the limiting column cooperates with the limiting groove under the action of gravity.

[0010] Furthermore, the length of the accommodating groove is not less than the length of the limiting column, and the length of the limiting column is greater than the length of the limiting groove, so that the limiting column is simultaneously located between the limiting groove and the accommodating groove, thereby limiting the splicing sections that are not in the same horizontal plane.

[0011] 3. Beneficial Effects

[0012] The advantages of the utility model compared with the prior art are:

[0013] The coordinated arrangement of the splicing sections, the connecting piece, the first hinge seat, the first threaded rod, the second hinge seat, the second threaded rod and the threaded barrel makes it easy for the splicing sections to be arranged in sequence into a ring structure. By driving the threaded barrel to rotate, the threaded barrel drives the first threaded rod and the second threaded rod on both sides to approach each other through a threaded connection, thereby making the splicing sections on the same horizontal plane form an annular structure to complete the pre-splicing, thereby achieving the purpose of preliminary positioning and avoiding the situation where the ends cannot be accurately matched due to splicing piece by piece.

[0022] Through the coordinated arrangement of the splicing segment 1, the connecting piece, the first hinge seat 2, the first threaded rod 3, the second hinge seat 4, the second threaded rod 5 and the threaded cylinder 6 in the above structure, after the splicing segments 1 on the same horizontal plane are placed, by driving the threaded cylinder 6, the threaded cylinder 6 drives the first threaded rod 3 and the second threaded rod 5 on both sides to approach each other through the threaded connection, thereby making the splicing segments 1 on the same horizontal plane form a whole.

[0023] Embodiment 2

[0024] Based on the first embodiment, combined with the attached Figure 4 The adjacent splicing sections 1 that are not in the same horizontal plane are arranged alternately, and the splicing sections 1 on different horizontal planes are limited and clamped together. The top of the lower splicing section 1 is connected with a limiting groove 10, and the limiting groove 10 is evenly arranged in an array with the annular structure as the axis. In a specific implementation, the top of the limiting groove 10 can be a hollow inverted cone structure to facilitate the insertion of the limiting column 11. A limiting column 11 is provided in the limiting groove 10, and a receiving groove 12 is relatively connected to the bottom end of the top splicing section 1. The other end of the limiting column 11 extends into the receiving groove 12, and the length of the limiting column 11 is greater than the length of the limiting groove 10.

[0025] The matching arrangement of the limiting groove 10, the limiting column 11 and the containing groove 12 in the above structure facilitates the connection of adjacent splicing sections 1 on different planes.

[0026] The specific usage is as follows:

[0027] First, after the splicing sections 1 are arranged in sequence into a ring structure, the inner covering portion 7 and the outer covering portion 8 are arranged in coordination to increase the contact area between adjacent splicing sections 1 on the same horizontal plane, and also facilitate the mutual positioning of adjacent splicing sections 1 after connection;

[0028] Then, by driving the threaded barrel 6 to rotate, the threaded barrel 6 drives the first threaded rod 3 and the second threaded rod 5 on both sides to approach each other through threaded connection, so that the splicing sections 1 on the same horizontal plane form a ring structure, so as to complete the pre-splicing and achieve the purpose of preliminary positioning;

[0029] Finally, when the splicing section of a horizontal plane is spliced, the adjacent splicing sections 1 that are not in the same horizontal plane are staggered with the splicing section 1 below. At this time, any splicing section 1 is connected to the other six splicing sections 1 at the same time, so as to facilitate improving the connection strength between the splicing sections 1. First, the limit column 11 is placed in the receiving groove 12. The length of the limit column 11 is greater than the length of the limit groove 10. The top of the limit groove 10 can be a hollow inverted cone structure, which is convenient for pre-positioning the limit column 11 and the receiving groove 12. By pouring a proper amount of concrete into the bottom of the receiving groove 12, and then cooperating the limit column 11 with the limit groove 10, the concrete is squeezed upward by the limit column 11 and introduced into the top of the limit groove 10, so that the limit column 11 is located between the limit groove 10 and the receiving groove 12, so that the splicing sections 1 that are not in the same horizontal plane can be limited to form a mixed tower.
