Technical Field

[0001] The utility model relates to the technical field of wind power tower hoisting, in particular to a wind power tower hoisting structure with adjustable hoisting points. Background Art

[0002] As the installed capacity of wind power equipment continues to increase, the length of wind power towers has also developed into many models. The lengths of towers of different models are also different. During the hoisting process of the tower, a hoisting structure is often needed to assist in the hoisting. In addition, the tower in the same unit is often divided into several sections, and the lengths of towers in different sections are also different. Therefore, the hoisting points of the hoisting structure need to be able to be adjusted to meet the requirements of towers of different lengths with appropriate hoisting point spacing during hoisting to ensure the safety of the hoisting operation.

[0003] In the prior art, the wind turbine tower is hoisted by means of transverse fastening screws, while most of the fastening screws for hoisting the wind turbine tower are vertical, which reduces the applicability of the wind turbine tower hoisting device and is inconvenient for users.

[0004] For example, a wind turbine tower hoisting mechanism disclosed in Chinese patent CN220415586U achieves the purpose of preventing the vertical fastening bolts from detaching from the tower body by providing a fastening mechanism, thereby improving the safety of the tower body hoisting and meeting the user's use needs. By providing a connecting structure, the tower body is hoisted, the risk of the wind turbine tower falling off the clamp is reduced, and the use of the user is convenient.

[0005] However, the device cannot adjust the distance between the lifting ears of the hanging beam according to the different lengths of the wind turbine tower during use, and its practicality is low.

[0006] For this reason, we urgently need to provide a wind power tower hoisting structure with adjustable hoisting points. Utility Model Content

[0007] The utility model aims to provide a wind turbine tower hoisting structure with adjustable hoisting points, so as to solve the problem in the above-mentioned background technology that the distance between the lifting ears of the hanging beam cannot be adjusted according to the different lengths of the wind turbine tower during use, resulting in low practicality.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind power tower hoisting structure with adjustable hoisting points, comprising a hoisting beam, an adjusting device is arranged inside the hoisting beam, and the adjusting device comprises an adjusting unit and a supporting unit.

[0009] The adjusting unit is arranged on the left and right sides of the hanging beam, and the supporting unit is arranged inside the hanging beam.

[0010] The adjustment unit includes a moving block, a lifting ear, a limit block, a threaded rod, a knob and a bearing. The left and right sides of the hanging beam are provided with accommodating cavities. The moving block is slidably connected to the left and right accommodating cavities. The lifting ears are fixedly installed on the front and rear sides of the moving block. The limit block is fixedly installed around the outside of the moving block. The threaded rod is threadedly connected to the inside of the moving block and one end extends to the outside of the hanging beam. The knob is fixedly installed on one end of the threaded rod. The bearing is fixedly installed on the inner wall of the accommodating cavity.

[0011] Preferably, the support unit includes a reinforcing plate and a slider rod, the reinforcing plate is installed on the left and right sides of the moving block, the slider is fixedly installed on the front and rear ends of one side of the reinforcing plate close to the moving block, and the lever is fixedly installed on the front and rear sides of the reinforcing plate.

[0012] Preferably, the front and rear two lifting ears are respectively sleeved with lifting straps, and are connected to the wind turbine tower through the lifting straps, so as to realize the lifting of the wind turbine tower.

[0013] Preferably, one end of the threaded rod located inside the accommodating cavity is fixedly mounted on the inner ring of the bearing, and the threaded rod is supported by the bearing.

[0014] Preferably, the front and rear surfaces of the suspension beam are provided with sliding grooves with a width equal to that of the limiting blocks, and the four limiting blocks are slidably connected in the sliding grooves, and the limiting blocks cooperate with the sliding grooves to limit the movement of the moving block.

[0015] Preferably, the slider is T-shaped, and the left and right side surfaces of the moving block are provided with T-shaped grooves of the same shape as the slider, and the slider is slidably connected inside the T-shaped groove, so that the reinforcement plate can move up and down along the T-shaped groove through the slider.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The wind turbine tower hoisting structure with adjustable lifting points can adapt to lifting points at different distances. By setting an adjustment unit, when the position of the lifting ear needs to be adjusted, the knob is turned to drive the threaded rod to rotate. When the threaded rod rotates, the moving block is threadedly connected, so that the moving block drives the lifting ear to move to a suitable position along the slide groove through the limit block, thereby adjusting the position of the lifting ear, thereby facilitating the hoisting of wind turbine towers of different lengths, and solving the problem of low practicality that the lifting ear distance of the hanging beam cannot be adjusted according to the different lengths of the wind turbine tower during use as proposed in the background technology.

[0019] 2. The wind turbine tower hoisting structure with adjustable lifting points, by setting a support unit, limits the relative sliding of the moving block by cooperating with the reinforcing plate and the arc groove when hoisting the wind turbine tower, thereby improving the hoisting safety and reducing the excessive force on the threaded rod, which may cause damage to the threaded rod. It has high safety performance and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 2:

[0033] On the basis of the first embodiment: the support unit includes a reinforcing plate 301, a slider 302 and a lever 303. The reinforcing plate 301 is installed on the left and right sides of the moving block 201. The slider 302 is fixedly installed on the front and rear ends of the reinforcing plate 301 close to the moving block 201. The lower surface of the accommodating cavity opened by the hanging beam 1 is provided with an arc groove that matches the bottom of the reinforcing plate 301, and the arc groove is equidistantly opened on the lower surface of the accommodating cavity. The reinforcing plate 301 is connected with the arc groove to prevent the moving block 201 from sliding relative to each other, and at the same time, the threaded rod is prevented from sliding. 204 is subjected to excessive force, resulting in damage to the threaded rod 204.
