Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub hoisting, in particular to a wheel hub hoisting fixture. Background Art

[0002] Wind turbine hub hoisting refers to the process of installing the wind turbine hub assembly to the top of the tower during the construction of a wind farm. The hub is an important component that connects the wind turbine blades and the generator. It supports the entire wind turbine system and transmits its rotating power to the generator. Hub hoisting usually requires the use of large lifting machinery, such as crawler cranes or self-elevating and self-propelled integrated offshore wind power installation platforms, to complete high-altitude operations. This process requires extremely high precision and requires the precise docking of the hub and blades under the control of multiple factors such as wind power, mechanical stability, and operator cooperation.

[0003] The existing wheel hub hoisting usually requires large tools such as cranes to carry it. Due to its relatively large size and weight, it takes a lot of time and manpower to connect and fix it. After the transportation is completed, it takes a lot of time to dismantle it, which affects the project efficiency. Utility Model Content

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figure 1 , which is the first embodiment of the utility model, provides a hub hoisting clamp that can quickly achieve the effect of hoisting and fixing the clamp to the hub.

[0029] Specifically, it includes a bearing assembly 100, including a bearing plate 101 and a bearing rod 101a disposed inside the bearing plate 101,

[0030] The shrinking assembly 200 includes a shrinking plate 204 disposed above the carrier plate 101 , a sliding plate 204 a disposed below the shrinking plate 204 , and a limiting block 204 a - 1 disposed below the sliding plate 204 a .

[0031] The bearing assembly 100 further includes a bearing ring 101a - 1 disposed above the bearing rod 101a , and a sliding rod 102 is disposed inside the bearing rod 101a . The bearing rods 101a are disposed in an annular array on the inner side of the bearing plate 101 .

[0032] Usage process: first place the clamp in the wheel hub hoist, and drive the sliding rod 102 to rise. During the rising process of the sliding rod 102, the sliding rod 102 drives the sliding plate 204a to slide in the load-bearing rod 101a through squeezing, and moves backward, and then drives the retractable plate 204 to move backward through the sliding plate 204a. Because the retractable plate 204 is inclined, the diameter of the retractable plate 204 is larger than the diameter of the wheel hub hoist opening, so that the retractable plate 204 is against the opening in the wheel hub hoist, thereby fixing it for subsequent transportation.

[0033] Example 2

[0034] Reference Figures 1 to 5 , which is the second embodiment of the utility model, provides a wheel hub hoisting fixture that can achieve the effect of fast and convenient fixed connection of the wheel hub hoisting.

[0035] Specifically, the shrinking component 200 also includes a first connecting plate 201 arranged on the outside of the sliding rod 102, a first rotating shaft 201a is provided on the inner side of the first connecting plate 201, an operating rod 203 is provided on the outer side of the first rotating shaft 201a, a second connecting plate 202 is provided on the inner side of the shrinking plate 204, a second rotating shaft 202a is provided on the inner side of the second connecting plate 202, a sliding groove 205 is provided inside the load-bearing rod 101a, and the sliding plate 204a is connected to the sliding groove 205.

[0036] The first connecting plates 201 are arranged in a circular array on the outer side of the sliding rod 102 .

[0037] The top of the retractable plate 204 is smooth and made of rubber. By setting the top of the retractable plate 204 to rubber, when the retractable plate 204 is fixed in the wheel hub hoist and drives it to move, it will not cause wear or damage to the inside.

[0038] The shrinking plates 204 are arranged in a circular array in the carrier plate 101 . The shrinking plates 204 are inclined. When the shrinking plates 204 move outward, the diameter of the entire fixture is expanded due to the inclined state of the shrinking plates 204 .

[0039] Usage process: In the initial state, the sliding rod 102 is located below the carrying ring 101a-1, and the operating rod 203 is in a tilted state from bottom to top. When the sliding rod 102 moves up, the sliding rod 102 will drive the multiple first connecting plates 201 and the first rotating shaft 201a on the outside to rise, and the first rotating shaft 201a drives the lower end of the operating rod 203 to rise. When the first rotating shaft 201a drives the operating rod 203 to rise to a certain height, the operating rod 203 is in a parallel state and pushes the retracting plate 204 to move outward. Since the retracting plate 204 is tilted, the overall diameter of the clamp is larger than the opening diameter in the wheel hub hoisting, so that the clamp is fixed in the wheel hub hoisting and cannot come out, thereby realizing a convenient and fast fixed connection to the wheel hub hoisting, which is convenient for subsequent transportation.

[0040] Example 3

[0041] Reference Figures 1 to 5 , which is the third embodiment of the utility model, and this embodiment provides a wheel hub lifting fixture that can achieve the effect of preventing it from falling off due to shaking during transportation.

[0042] Specifically, it also includes a stabilizing assembly 300, which includes a fixing plate 301 arranged above the sliding rod 102, a first connecting long plate 302 arranged inside the fixing plate 301, a first inclined plate 302a arranged above the first connecting long plate 302, a second connecting long plate 303 arranged inside the first connecting long plate 302, a second inclined plate 303a arranged above the second connecting long plate 303, a hook groove 304 is provided at one end of the first inclined plate 302a and the second inclined plate 303a, and a sharp plate 305 is provided at one end of the first inclined plate 302a and the second inclined plate 303a. The hook groove 304 is arranged on the first inclined plate 302a and the second inclined plate 303a, and the hook groove 304 is in a ratchet shape. The sharp plate 305 is in an inclined hook shape.

[0043] Usage process: First, use a crane or other transport tool to hook the connection object under the first inclined plate 302a and the second inclined plate 303a. When shaking occurs during transportation and movement, the connection object is limited by the oblique ratchet grooves of the multiple hook grooves 304, so that the connection object cannot move at the hook grooves 304, thereby preventing the connection object from falling off the wheel hub when shaking occurs during transportation.
