Description

A fan variable pitch motor installation tool Technical Field

The present invention relates to the technical field of motor installation tools, and in particular to a wind turbine variable pitch motor installation tool.

Background Art

A variable pitch wind turbine is a device used for wind power generation, also known as a wind turbine. It consists of a wind rotor, a main shaft, a variable pitch mechanism, a generator, etc. The wind rotor is the core component of the wind turbine, usually composed of several blades, the angle of which can be adjusted according to the size and direction of the wind. The variable pitch mechanism is used to control the angle of the blades so that the wind rotor can automatically adjust the angle of the blades according to the change in wind force, thereby maximizing the capture of wind energy. The generator converts the rotation of the wind rotor into electrical energy for use or storage in the power grid.

When installing a variable pitch motor, two people are usually required to operate it. One person is responsible for lifting the motor, and the other person uses lighting equipment to check whether the motor is aligned with the variable pitch gearbox. Only when the shaft key is aligned with the keyway can the motor be safely lowered. This process is a great test of the coordination ability of the personnel. There are safety hazards such as squeezing and smashing during the operation, and the efficiency is relatively low.

Example 2

3 , this embodiment is different from the first embodiment in that: in order to keep the wind turbine pitch motor stable when the wind turbine pitch motor and the pitch gear set are connected by bolts, the wind turbine pitch motor installation tool further includes a positioning mechanism 400; the wind turbine pitch motor being connected to the pitch gear set is fixed by the positioning mechanism 400, and the positioning mechanism 400 includes a placement seat 401, which is provided on the supporting beam 302/moving beam 301, and between the supporting beam 302 and the moving beam 301. 01 are both connected to a mounting seat 401; a clamping member 402 is slidably arranged on the mounting seat 401, and the two mounting seats 401 are both provided with a clamping member 402, and the two clamping members 402 can be close to each other to clamp the wind turbine pitch motor therebetween; an adjusting screw rod 403 is threadedly connected to the mounting seat 401, and can drive the clamping member 402 to move, and the two mounting seats 401 are both provided with an adjusting screw rod 403, and the positions of the two clamping members 402 are adjusted by adjusting the screw rod 403.

The clamping member 402 can be a straight bar type or an arc type, so as to adapt to wind turbine pitch motors of different shapes. The clamping member 402 has two limit rods 404, and the two limit rods 404 are slidably connected to the mounting seat 401, which can avoid the problem of rotation of the clamping member 402.

The rest of the structure is the same as that of Example 1.

Operation process: When the wind turbine pitch motor and the pitch gear set are connected, by rotating the two adjustment screws 403, the two clamping members 402 can be driven so that the two clamping members 402 approach each other and resist the wind turbine pitch motor from both sides, so that the wind turbine pitch motor remains stable during the connection.

Example 3

3 and 4, this embodiment is different from the above embodiment in that: in order to adjust the position of the positioning mechanism 400 so that the position of the positioning mechanism 400 and the position of the wind turbine pitch motor can correspond, the pitch motor installation tool also includes a connection between the placement seat 401 and the support beam 302/moving beam 301 The installation mechanism 500 includes a placement rod 501 installed on the support beam 302/movable beam 301; a mounting member 502, which is disposed on the placement rod 501 and can move along the placement rod 501;

The supporting crossbeam 302 and the movable crossbeam 301 are both provided with mounting mechanisms 500. The supporting crossbeam 302 and the movable crossbeam 301 are both provided with socket grooves M. The mounting rod 501 is mounted on the inner side of the socket groove M. The mounting component 502 can slide along the mounting rod 501, and the sliding direction is the second direction, so that the operator can adjust the position of the mounting component 502 by the position of the wind turbine pitch motor, thereby adjusting the position of the positioning mechanism 400, so that the positioning mechanism 400 can be aligned with the wind turbine pitch motor installation tooling.

The rest of the structure is the same as that of Example 2.

Operation process: When the position adjustment of the wind turbine pitch motor is completed, it is aligned with the pitch gearbox. At this time, the position of the mounting component 502 can be adjusted so that the mounting component 502 drives the mounting seat 401 to move, thereby achieving the movement of the clamping member 402.

Example 4

5 to 6, this embodiment is different from the above embodiments in that: in order to avoid operating errors by the operator, the tooling is withdrawn before the connection between the wind turbine pitch motor and the pitch gearbox is completed, and the pitch motor installation tooling also includes a warning mechanism 600, which includes a sleeve group 601 arranged between the supporting beam 302 and the movable beam 301, a force-bearing component 602 fixed at both ends of the sleeve group 601, an elastic member 603 in conflict with the force-bearing component 602, and an elastic member 603 arranged at the force-bearing component The warning column 604 on the component 602; the pushing mechanism includes a roller 701 arranged at the end of the placement rod 501, a pushing arm 702 and a resisting arm 703 arranged on the outside of the roller 701; the roller 701 arranged at the support beam 302 and the roller 701 arranged at the moving beam 301, and the pushing arm 702 and the resisting arm 703 arranged on the two are in a mirror-symmetrical relationship; the warning column 604 is located on the inner side of the support beam 302/moving beam 301 in the natural state, When the roller 701 provided at the supporting beam 302 rotates in the same direction as the roller 701 provided at the moving beam 301 , the warning column 604 can be extended. When the operator finds that the warning column 604 is extended, it can be understood that the wind turbine pitch motor and the pitch gearbox are not connected.

In this embodiment, the supporting beam 302 and the moving beam 301 are provided with trigger chambers N at both ends of the sleeve groove M. The two ends of the placement rod 501 are cylindrical, and the cross-section of the middle part is rectangular. The two ends of the placement rod 501 and the supporting beam 302 or the moving beam 301 are in a rotational connection relationship, and the two ends of the placement rod 501 extend to the inner side of the trigger chambers N at both ends of the sleeve groove M respectively.

Specifically, the sleeve assembly 601 includes an external pipe member 601a slidably disposed on the movable crossbeam 301, and an internal column member 601b slidably disposed on the supporting crossbeam 302;

When the supporting beam 302 and the secondary wheel seat body 301a-2 are connected, the external tube component 601a is sleeved on the outside of the internal column component 601b, and the external tube component 601a and the internal column component 601b are abutted against each other. A sliding column 601c is fixed to the ends of the external tube component 601a and the internal column component 601b that are away from each other. The two sliding columns 601c are respectively slidably connected to the supporting beam 302 and the movable beam 301. The end of the sliding column 601c away from the sleeve group 601 extends to the inner side of the trigger chamber N, and the force-bearing component 602 is fixed to the sliding column 601c at one end of the trigger chamber N.

The warning column 604 is fixed to one end of the force-bearing component 602 away from the sliding column 601c, and an exposure hole N1 corresponding to the warning column 604 is opened on the side wall of the trigger chamber N. The elastic member is a spring, which is sleeved on the outside of the warning column 604 and is against the force-bearing component 602. In the natural state, the elastic members at both ends reach a balanced state, and the warning columns 604 at both ends will not be exposed from the exposed part.

In this embodiment, the through groove 502a on the mounting member 502 is a rectangular groove, and its width is adapted to the width of the mounting rod 501. The two ends of the two clamping members 402 are provided with synchronization holes 403a. Through the existing technology of long studs (not shown in the figure) and nuts, the two ends of the two clamping members 402 can be connected one by one, so that the wind turbine pitch motor is located between the two clamping members 402 and the two long studs.

When the wind turbine pitch motor and the pitch gearbox are connected and the lifting top plate 201 continues to descend, the adjustment platform 303 no longer supports the wind turbine pitch motor. However, at this time, the two clamping members 402 are clamped on the outside of the wind turbine pitch motor, and the placement rod 501 descends along the through slot 502a.

The force-bearing component 602 is provided with a pushing groove 602 a at a position corresponding to the pushing arm 702 , and the force-bearing component 602 is provided with a resisting portion 602 b at a position corresponding to the resisting arm 703 .

In this embodiment, the force-bearing member 602 is U-shaped, and the thrust groove 602a is located at the bottom of the force-bearing member 602. In the natural state, the pushing arm 702 passes through the thrust groove 602a and penetrates the force-bearing member 602, and contacts the end of the thrust groove 602a. In the natural state, the contact arm 703 and the contact part 602b are in a separated state, so that the force-bearing member 602 is The force member 602 can be pushed by a small amplitude.

When the wind turbine pitch motor and the pitch gearbox are connected and the lifting top plate 201 continues to descend, the adjustment platform 303 no longer supports the wind turbine pitch motor. If the wind turbine pitch motor and the pitch gearbox are not connected at this time, or the connection is not completed, the wind turbine pitch motor is not sufficiently fixed and may tip over. When it tips over in the direction of one of the clamping members 402, the corresponding clamping member 402 will drive its corresponding mounting component 502 to swing under its thrust. At the same time, because the two clamping members 402 are in a connected state, when one of the clamping members 402 moves away from the wind turbine pitch motor under the thrust of the tipping of the wind turbine pitch motor, the other clamping member 402 will also move in the same direction, thereby causing the two mounting components 502 to swing synchronously.

The synchronous swinging of the two mounting components 502 will drive the two placement rods 501 to rotate in the same direction, thereby driving the two rollers 701 to rotate synchronously. At this time, the pushing arm 702 on one of the rollers 701, referred to as the A roller 701, will push its corresponding force-bearing component 602, referred to as the A force-bearing component 602, toward the other roller 701. Under the transmission of the sleeve group 601, the other force-bearing component 602, referred to as the B force-bearing component 602, also moves closer to its corresponding roller 701, referred to as the B roller 701. At this time, the B roller 701 also rotates synchronously with the A roller 701, so that the resistance arm 703 on the B roller 701 resists the resistance part 602b of the B force-bearing component 602, so that the B force-bearing component 602 cannot be pushed further. At this time, the A roller 701 cannot be disengaged from the inner side of the push groove 602a due to the small rotation angle, so it cannot rotate and is locked, thereby making the wind turbine pitch motor unable to continue to tilt.

Therefore, in addition to connecting the two clamping members 402 through a long stud, the two clamping members 402 may also be connected through a connecting rod with rotatable ends.

At the same time, due to the small displacement of the B load-bearing member 602, the warning column 604 installed thereon extends out from the exposure hole N1, reminding the operator that the wind turbine pitch motor is experiencing a tilt problem.

Through the above structure, before completely removing the tooling, the stability of the wind turbine pitch motor can be preliminarily tested through the warning mechanism 600. The wind turbine pitch motor can be slightly tilted under the action of the clamping member 402. After the slight tilt, it will be supported by the clamping member 402, and the thrust caused by the slight tilt can be displayed through the warning column 604, reminding the operator of the main problem of unstable installation.

The rest of the structure is the same as that of Example 3.
