[0030] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] In related technologies, the installation of the web plate is mainly carried out manually. Relying on manpower to move the web plate to the appropriate position can easily lead to inaccurate positioning, which affects the quality of the finished blade. Therefore, a wind turbine blade web plate positioning device is needed to position the web plate.

[0032] Specifically, the web plate installation operation of the relevant technology has the following shortcomings:

[0033] 1. Relying on manual labor to move the root end of the web plate to the appropriate position is time-consuming and laborious, and the accuracy of the positioning and installation cannot be guaranteed;

[0034] 2. When installing the web plate, lifting equipment is generally used to move the web plate up and down. During the installation, the web plate may shift at an angle. Relying on manual positioning may not be able to detect the angle shift of the web plate in time, and manual positioning cannot guarantee the accuracy of the installation.

[0035] 3. When installing the web plate, lifting equipment is generally used to move the web plate up and down. During the up and down movement, the web plate may sway. When positioning manually, it may not be possible to achieve accurate positioning, which has the disadvantage of not being able to meet people's usage needs.

[0036] Based on this, the present invention proposes a wind turbine blade web positioning device to overcome or partially overcome the above-mentioned shortcomings. The embodiments provided by the present invention will be described in detail below.

The first hydraulic push rod 402 can move the entire assembly consisting of the rotating component 5, the clamping component 6, and the first clamping plate 206 and the second clamping plate 207 forward or backward, so that the first clamping plate 206 and the second clamping plate 207 clamp and fix the blade web and drive it to move. The rotating component 5 can rotate the entire assembly consisting of the clamping component 6 and the first clamping plate 206 and the second clamping plate 207 to adapt to different installation angles of the blade web. The distance adjustment mechanism is used to adjust the first clamping plate 206 and the second clamping plate 207 to adapt to blade webs of different thicknesses. Multiple adsorption plates 205 are used to adsorb and fix the blade web. The lifting component 3 is used to drive the entire assembly consisting of the first hydraulic push rod 402, the rotating component 5, the clamping component 6, the first clamping plate 206 and the second clamping plate 207 to move up and down, so as to adjust the height of the blade web when the first clamping plate 206 and the second clamping plate 207 clamp the blade web.

[0048] In one embodiment of the present invention, the measuring component 7 further includes a camera 703, which is mounted and fixed to the fixing frame 701. The camera 703 is used to verify the actual installation position of the blade web after installation.

[0049] In the specific implementation, the camera 703 can capture and collect data on the installation and positioning of the web plate. The collected data can be compared with the saved data model to verify the actual installation position of the blade web plate after installation, ensuring the accuracy of the web plate positioning and installation.

[0050] In one embodiment of the present invention, the distance adjustment mechanism includes a U-shaped frame 601, the U-shaped frame 601 including a first vertical plate and a second vertical plate opposite to the first vertical plate, a first connecting plate 606 and a second connecting plate 607 and a sliding rod 604 passing through the first connecting plate 606 and the second connecting plate 607 are provided between the first vertical plate and the second vertical plate, the first connecting plate 606 is connected to the first clamping plate 206, and the second connecting plate 607 is connected to the second clamping plate 207; a second hydraulic push rod 605 is provided on the side of the first vertical plate away from the first connecting plate 606, and the second hydraulic push rod 605 is connected to the first connecting plate 606; a third hydraulic push rod 608 is provided on the side of the second vertical plate away from the second connecting plate 607, and the third hydraulic push rod 608 is connected to the second connecting plate 607.

[0052] In one embodiment of the present invention, the clamping assembly 6 further includes an L-shaped rod 602 and a push plate 603, one end of the L-shaped rod 602 being connected to the U-shaped frame 601 and the other end being connected to the push plate 603.

[0053] In specific implementations, such as Figure 3 As shown, the clamping assembly 6 also includes an L-shaped rod 602 and a push plate 603.

[0054] In one embodiment of the present invention, the L-shaped rod (602) is symmetrically distributed about the horizontal center line of the push plate (603), and the position of the distance sensor (507) is higher than the position of the push plate (603).

[0055] In specific implementations, such as Figure 3 As shown, the L-shaped rods 602 can be symmetrically distributed about the horizontal center line of the push plate 603, and the height of the distance sensor 507 can be slightly higher than the top of the push plate 603; the distance sensor 507 can measure the distance of the web plate, and can improve the accuracy of web plate positioning when moving the web plate.

[0056] In one embodiment of the present invention, a first motor 502 and a connecting rod 505 are provided inside the rotating component housing 501. One end of the connecting rod 505 is connected to the mounting plate 401, and the other end is connected to the clamping component 6. The output shaft of the first motor 502 is provided with a driving gear 503, and the connecting rod 505 is provided with a driven gear 504.

[0057] In specific implementations, such as Figure 5 As shown, a first motor 502 and a connecting rod 505 are provided inside the rotating component housing 501. One end of the connecting rod 505 is connected to the mounting plate 401, and the other end is connected to the clamping component 6. The output shaft of the first motor 502 is provided with a driving gear 503, and the connecting rod 505 is provided with a driven gear 504.

[0058] In practical applications, the driving gear 503 and the second motor 502 constitute a rotating mechanism, and the driving gear 503 and the connecting rod 505 constitute a transmission mechanism through the driven gear 504. The connecting rod 505 is rotatably mounted through one side of the rotating component housing 501. When the second motor 502 starts, the driving gear 503 drives the driven gear 504 to rotate, which in turn drives the connecting rod 505 to rotate. The rotation of the connecting rod 505 drives the entire assembly consisting of the clamping component 6, the first clamping plate 206, and the second clamping plate 207 to rotate. When the web plate is installed with the housing, the angle of the web plate can be adjusted by the rotating component 5, which facilitates the subsequent positioning and installation of the web plate.

A second motor 302 is provided at the top of the columnar shell 301. A screw 303 and a slider 304 are provided inside the columnar shell 301. The screw 303 passes through the slider 304. One end of the screw 303 is fixed to the bottom of the columnar shell 301, and the other end is connected to the second motor 302. The slider 304 is fixed to the mounting plate 401.

[0060] In specific implementations, such as Figure 6 As shown, the column includes a columnar shell 301. The bottom of the columnar shell 301 is fixed to the base 1 via a support column 102. A second motor 302 is provided at the top of the columnar shell 301. A screw 303 and a slider 304 are provided inside the columnar shell 301. The screw 303 passes through the slider 304. One end of the screw 303 is fixed to the bottom of the columnar shell 301, and the other end is connected to the second motor 302. The slider 304 is fixed to the mounting plate 401.

[0061] In practical applications, the slider 304 forms a helical transmission mechanism with the second motor 302 via the screw 303, and the slider 304 and the cylindrical housing 301 form a sliding structure. When the second motor 302 is started, the slider 304 is driven to slide up and down in the mounting housing 301 via the screw 303, which in turn drives the structure set on the mounting plate 401 to move up and down. Thus, the height of the first clamping plate 206 and the second clamping plate 207 can be adjusted according to the height position of the web, which facilitates the subsequent positioning of the web.

[0062] In one embodiment of the present invention, the conduit assembly includes a three-way pipe 202, which is connected to an air compressor 201, one end of a first hose 203, and one end of a second hose 208, respectively. The other end of the first hose 203 is connected to a first connecting pipe 204, and the other end of the second hose 208 is connected to a second connecting pipe 209. The first connecting pipe 204 is installed and fixed on the side of the first clamping plate 206 away from the adsorption plate 205 and communicates with the adsorption plate 205. The second connecting pipe 209 is installed and fixed on the side of the second clamping plate 207 away from the adsorption plate 205 and communicates with the adsorption plate 205.

[0063] In specific implementations, such as Figure 7 As shown, the conduit assembly includes a three-way pipe 202, which is connected to the air compressor 201, one end of the first hose 203, and one end of the second hose 208. The other end of the first hose 203 is connected to the first connecting pipe 204, and the other end of the second hose 208 is connected to the second connecting pipe 209. The first connecting pipe 204 is installed and fixed on the side of the first clamping plate 206 away from the adsorption plate 205 and communicates with the adsorption plate 205. The second connecting pipe 209 is installed and fixed on the side of the second clamping plate 207 away from the adsorption plate 205 and communicates with the adsorption plate 205.

[0064] In practical applications, the first hose 203 and the second hose 208, the first connecting pipe 204 and the second connecting pipe 209 can be symmetrically distributed about the center line of the tee pipe 202. When the air compressor 201 starts, the tee pipe 202, the first hose 203, the second hose 208, the first connecting pipe 204, the second connecting pipe 209 and the suction plate 205 can be used to adsorb the web plate from both ends. When the positioning device is used to position the web plate, the web plate can be stably adsorbed, and the position of the web plate can be stably adjusted afterwards.

[0065] In one embodiment of the present invention, the base 1 is further provided with an L-shaped plate 103, the L-shaped plate 103 is provided with a fourth hydraulic push rod 104, one end of the fourth hydraulic push rod 104 is fixed to the L-shaped plate 103, and the other end is connected to the caster wheel 105.

One end of the fourth hydraulic push rod 104 is installed and fixed to the L-shaped plate 103, and the other end is connected to the caster wheel 105.

[0067] In practical applications, such as Figure 9 As shown, the support plate 101 of the base 1 can be provided with four sets of through holes. The casters 105 and the fourth hydraulic push rod 104 constitute a lifting mechanism. The L-shaped plate 103, the fourth hydraulic push rod 104 and the casters 105 can be provided in four sets. At the same time, the L-shaped plate 103, the fourth hydraulic push rod 104 and the casters 105 are symmetrically distributed about the vertical center line of the support plate 101. When the four sets of fourth hydraulic push rods 104 are activated, they drive the corresponding casters 105 to move downward, pass through the corresponding through holes at the top of the support plate 101 and contact the ground, raising the device. This facilitates the subsequent movement of the positioning device via the casters 105, changing the working location of the positioning device.

[0068] In one embodiment of the present invention, the base 1 is further provided with a screw hole 106, which is used to install and fix the device to the ground.
