Description

Technical Field

[0001] This utility model relates to the field of wind power equipment hoisting technology, and in particular to a hub hoisting structure. Background Technology

[0002] Because different types of wind turbine hubs have different external dimensions, the accessible surfaces for hub lifting also differ. This results in the incompatibility of hub transfer and lifting fixtures for different models, increasing the cost of the fixtures used.

[0003] In the current scenario, workers often use three connecting hangers to achieve transfer on the outside of the wheel hub. However, in this process, personnel need to perform high-altitude operations on the upper part of the wheel hub. Due to the structural problems of the upper part of the wheel hub, the bolts at the connection between the hanger and the wheel hub cannot be pre-tightened with the pre-tightening force of standard bolts. Therefore, the time spent on disassembling and assembling the tooling is long, which often delays the overall assembly progress and increases the overall assembly time cost. Utility Model Content

[0004] The purpose of this utility model is to provide a wheel hub lifting structure that solves the problem that existing lifting fixtures cannot lift wheel hubs of different sizes.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: In the first aspect, this utility model provides a wheel hub lifting structure, including a tooling body, two sliders and at least two limiting components; The tooling body has sliding mounting grooves on its two opposite end faces. The two sliders are slidably mounted at both ends of the tooling body through the sliding mounting groove, and the sliding direction of the sliders is parallel to the guiding direction of the sliding mounting groove. Each of the sliders is provided with at least one limiting component, the fixed end of the limiting component is mounted on the slider, and the limiting end of the limiting component restricts the rotation and sliding of the hub.

[0006] As an optional solution, the limiting component includes a limiting plate, a fixing plate, and a fixing member; The bottom end face of the fixing plate and the top end face of the slider are fixedly installed by a fastener; One end of the limiting plate is fixedly connected to the fixing plate, and the included angle between the limiting plate and the fixing plate is α, where 0° < α < 90°.

[0007] As an optional solution, a stiffening plate is also provided between the fixing plate and the limiting plate.

[0008] As an optional solution, the top surface of the slider is also provided with at least two sets of positioning holes, which cooperate with the fixing member to fix the fixing plate, and the positioning holes extend along the sliding direction of the slider.

[0009] As an optional solution, it also includes at least two power components, each of which includes a push rod and a power source; At least one power component is mounted on each of the aforementioned sliders; The pushing end of the push rod is fixedly connected to the slider, the fixed end of the push rod is mounted on the tooling body, and the pushing force of the push rod is provided by the power source.

[0010] Alternatively, the guiding direction of the sliding mounting groove is parallel to the length direction of the tooling body.

[0011] This utility model has the following unexpected beneficial effects: 1. This utility model is provided with a tooling body, two sliders and at least two limiting components. The tooling body slides the two sliders through a sliding mounting groove. At least one limiting component for limiting the wheel hub is provided on each slider, so that the tooling body can lock wheel hubs of different specifications by adjusting the extension length of the slider, thereby solving the problem that the lifting tooling in the prior art cannot lift wheel hubs of different sizes.

[0012] 2. This utility model provides multiple sets of positioning holes on the slider for installing the limiting components, enabling the limiting components to have more precise fine-tuning means, thereby ensuring the stability and reliability of the tooling under different working conditions and preventing the wheel hub from sliding during use.

Detailed Implementation

[0015] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0016] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In the description of this utility model, it should be understood that the terms "connected," "linked," and "fixed," etc., used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a welded connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] In one embodiment, such as Figures 1 to 3 As shown, in a first aspect, this utility model provides a wheel hub lifting structure, including a tooling body 1, two sliders 2 and at least two limiting components 3.

[0019] The tooling body 1 has sliding mounting grooves 101 on its two opposite end faces; the tooling body 1 is a cuboid structural block, and the top of the tooling body 1 is provided with a hook for connecting the hoisting device. The two opposite end faces of the tooling body 1 have through mounting cavities, and the sliding mounting grooves 101 are provided on the walls of the mounting cavities. The sliding mounting grooves 101 are embedded T-shaped grooves.

[0020] The two sliders 2 are slidably mounted at both ends of the tooling body 1 via the sliding mounting groove 101, and the sliding direction of the sliders 2 is parallel to the guiding direction of the sliding mounting groove 101.

[0021] The number of sliding mounting slots 101 is not further limited here. To ensure the smooth sliding of the slider 2, any slider 2 can be slidably mounted through four sliding mounting slots 101, and any side of the slider 2 is connected to two sliding mounting slots 101.

[0022] At least one limiting component 3 is provided on any of the sliders 2. The fixed end of the limiting component 3 is installed on the slider 2, and the limiting end of the limiting component 3 restricts the rotation and sliding of the wheel hub.

[0023] Based on this, the main body 1 of the lifting structure has sliding mounting grooves 101 on its two opposite end faces. The slider 2 is slidably installed in the mounting cavity through the sliding mounting grooves 101. The limiting end of the limiting component 3 restricts the rotation and slippage of the wheel hub. This ensures that when the main body 1 lifts wheel hubs of different sizes, the limiting end of the limiting component 3 restricts the rotation and slippage of the wheel hub during the lifting process by sliding the slider 2. This solves the problem that the lifting fixture in the prior art cannot lift wheel hubs of different sizes.

[0024] Furthermore, such as Figures 1 to 3 As shown, the limiting component 3 includes a limiting plate 302, a fixing plate 301, and a fixing member 303.

[0025] The bottom surface of the fixing plate 301 and the top surface of the slider 2 are fixedly installed by the fixing member 303.

[0026] The structure of the fastener 303 is not further defined here. The fastener 303 is a standard part (bolt or pin).

[0027] One end of the limiting plate 302 is fixedly connected to the fixing plate 301. The included angle between the limiting plate 302 and the fixing plate 301 is α, where 0° < α < 90°. In this case, the limiting plate 302 is the limiting end of the limiting component 3, and the fixing plate 301 is the fixing end of the limiting component 3. Since the contact surface between the wheel hub and the limiting plate 302 is curved, and the surface of the fixing plate 301 is always perpendicular to the direction of gravity after it follows the slider 2 into the wheel hub, when the limiting plate 302 and the fixing plate 301 are in contact, the contact surface between the limiting plate 302 and the fixing plate 301 is fixed. When the included angle between the limiting plate 302 and the fixing plate 301 is 0° or 90°, the limiting plate 302 and the fixing plate 301 are parallel or perpendicular. No matter how much the slider 2 is displaced, the limiting plate 302 only has one edge in contact with the abutment surface of the wheel hub, and the abutment action cannot be completed. When the included angle between the limiting plate 302 and the fixing plate 301 is an acute angle, a "pocket" or "hook" shaped structure is formed. When the wheel hub is lifted, the inclined surface generates a centripetal component force to automatically "hug" or "lock" the wheel hub, thereby realizing the abutment of the wheel hub.

[0028] Furthermore, such as Figures 1 to 3As shown, a stiffening plate 304 is also provided between the fixing plate 301 and the limiting plate 302.

[0029] The number of stiffening plates 304 is not further limited here. Although increasing the number of stiffening plates 304 between the fixed plate 301 and the limiting plate 302 can increase the structural strength, since the stiffening plates 304 are cheap steel plates, they have a certain mass. If too many are added, it will greatly increase the workload of the lifting device. Therefore, in actual use, it is necessary to balance the structural strength and the tension of the lifting device during operation.

[0030] Furthermore, such as Figures 1 to 3 As shown, the top surface of the slider 2 is also provided with at least two sets of positioning holes 201. The positioning holes 201 cooperate with the fixing member 303 to fix the fixing plate 301, and the positioning holes 201 extend along the sliding direction of the slider 2.

[0031] The structure of the positioning hole 201 and the fixing member 303 is not further limited here. The number of fixing members 303 on the slider 2 corresponds to the number of positioning holes 201 in a single set of positioning holes 201. When the fixing member 303 is a bolt, the positioning hole 201 is a threaded hole. When the fixing member 303 is a pin, the positioning hole 201 is not specially set, and it is only necessary to ensure that its hole wall can withstand the lateral force given by the pin. By setting multiple sets of positioning holes 201, multiple slider 2 positions can be preset for different models of wheel hubs, thereby achieving fast and accurate positioning, saving the trouble of measuring every time the wheel hub is changed, and improving production efficiency while ensuring the stability of wheel hub lifting.

[0032] Furthermore, such as Figures 1 to 3 As shown, it also includes at least two power components 4, each of which includes a push rod 401 and a power source 402.

[0033] At least one power component 4 is installed on any of the sliders 2.

[0034] The pushing end of the push rod 401 is fixedly connected to the slider 2, and the fixed end of the push rod 401 is installed on the tooling body 1. The pushing force of the push rod 401 is provided by the power source 402.

[0035] The type of power source 402 is not further limited here. Pneumatic, hydraulic and electric power sources 402 can be selected according to actual needs. When needed, the power source 402 pushes the push rod 401 to move, thereby driving the slider 2 to move. It should be noted that since no additional limiting mechanism is set on the slider 2, the position of the slider 2 after sliding is also provided by the power source 402.

[0036] Furthermore, such as Figures 1 to 3 As shown, the guiding direction of the sliding mounting groove 101 is parallel to the length direction of the tooling body 1.

[0037] Since both sliders 2 are located in the mounting cavity, the sliding mounting grooves 101 at both ends of the tooling body 1 can be connected for the purpose of simplifying the processing technology. At this time, the force generated during lifting can be smoothly transmitted along the main load-bearing direction (length direction) of the tooling body 1, thereby ensuring the rationality of the lifting structure described in this utility model.

[0038] The working process of this utility model is as follows: the lifting fixture is inserted into the hub from the installation side of the hub. After the fixture body 1 is suspended, its length direction is perpendicular to the direction of gravity. The power source 402 is started so that the two sliders 2 are pushed out until the two limiting plates 302 abut against the contact surface of the hub. The lifting device is started to complete the lifting of the hub. The power source 402 is started again so that the sliders 2 return to the initial position. Finally, the fixture body 1 is removed from the hub to end the lifting process.

[0039] In summary, the lifting structure achieves the extension and retraction of the lifting tool length through the slider 2 set on its tooling body 1. After sliding, the slider 2 abuts against the inner contact surface of the wheel hub through the limiting component 3 designed on it. This ensures that when the tooling body 1 lifts wheel hubs of different sizes, the limiting end of the limiting component 3 can restrict the rotation and slippage of the wheel hub during the lifting process by sliding the slider 2. This solves the problem that the existing lifting tooling cannot lift wheel hubs of different sizes.

[0040] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
