Description

Technical Field

[0001] This utility model relates to the field of blade lifting technology, and in particular to a transport blade lifting anti-tilt test device. Background Technology

[0002] Wind turbine equipment used for wind power generation mainly includes wind turbine blades, nacelles, hubs and towers. Each component is an oversized item that cannot be transported by ordinary road and requires the use of special vehicles for transportation. As for the blades, their extra-long length is the main feature that distinguishes them from other parts of the wind turbine. The longer the blades, the more difficult and costly the transportation becomes.

[0003] However, during the horizontal rotation adjustment of wind turbine blades, the overall center of gravity of the vehicle body will shift. If the shift is too large, it is easy to overturn and cause economic losses. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a transport blade lifting anti-tilt testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A transport blade lifting anti-tilt testing device includes a base, an mounting frame on the upper surface of the base, a fixing plate fixedly connected to the upper surface of the mounting frame at the end, a fixing sleeve fixedly connected to one side of the fixing plate, a simulated wind turbine blade installed inside the fixing sleeve, a locking component for fixing the simulated wind turbine blade on the outer side of the fixing sleeve, a reduction motor fixedly connected inside the base, and one end of the output shaft of the reduction motor fixed to the mounting frame.

[0007] As a further embodiment of this utility model, the locking component includes two screws, and the outer side of the fixing sleeve has two symmetrically distributed threaded holes. The two screws are respectively threaded into the two threaded holes, so that the screws lock the simulated wind turbine blades.

[0008] As a further embodiment of this utility model, a support plate is fixedly connected to one side of the mounting bracket, an electric push rod is fixedly connected to the upper surface of the support plate, and a connecting shaft is fixedly connected to one end of the telescopic part of the electric push rod.

[0009] As a further embodiment of this utility model, the upper surface of the mounting bracket is provided with a sliding groove, a T-shaped plate is slidably connected in the sliding groove, and the connecting shaft is fixed to the T-shaped plate.

[0010] As a further embodiment of this utility model, a connecting block is fixedly connected to the upper surface of the T-shaped plate, and an installation hole is opened on one side of the connecting block. A dual-shaft extension synchronous cylinder is fixedly connected in the installation hole. Arc-shaped frames are fixedly connected to the telescopic parts at both ends of the dual-shaft extension synchronous cylinder, and multiple angle displacement sensors are fixedly connected to one side of the arc-shaped frame.

[0011] As a further embodiment of this utility model, a controller is fixedly connected to the upper surface of the mounting bracket, and the controller is electrically connected to the angle displacement sensor and the electric push rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By rotating the mounting bracket, the simulated wind turbine blades are rotated horizontally, thereby changing the angle of the simulated wind turbine blades. The test is conducted to determine the angle at which the simulated wind turbine blades will tilt, thus testing the rotation angle. This is beneficial for optimizing the safety performance of the hydraulic control device during the production process of the lifting vehicle's hydraulic control.

[0014] 2. By setting up an angle displacement sensor, the angle displacement sensor can detect the swaying amplitude during the transportation of simulated wind turbine blades. The swaying data can be used to determine whether the current vehicle speed is appropriate, and the vehicle speed can be controlled based on the test results. Attached Figure Description

The simulated wind turbine blade 2 is placed into the fixing sleeve 6, and then the screws 9 are locked and fixed to the simulated wind turbine blade 2 through the threaded holes on the fixing sleeve 6.

[0021] In this utility model, a geared motor 10 is fixed inside the base 11 by bolts, and one end of the output shaft of the geared motor 10 is fixed to the mounting frame 5. The model of the geared motor 10 is DSZRF27-58. After the simulated wind turbine blade 2 is fixed, the geared motor 10 is started. The geared motor 10 drives the mounting frame 5 to rotate, and the mounting frame 5 drives the simulated wind turbine blade 2 to rotate horizontally, thereby changing the angle of the simulated wind turbine blade 2. The angle at which the simulated wind turbine blade 2 will tilt is tested, thereby testing the rotation angle. This is beneficial for optimizing the safety performance of the hydraulic control device based on the test results during the production process of hydraulic control of the lifting vehicle.

[0022] In this utility model, a support plate is welded to one side of the mounting bracket 5. An electric push rod 3 is fixed to the upper surface of the support plate by bolts.

Multiple angle displacement sensors 13 are fixed to one side of the arc-shaped frame 1 by bolts. The device 13, model RHM0250MD601A01, is installed on a vehicle to simulate the transportation of the blade. The angle displacement sensor 13 on the arc frame 1 detects the amplitude of the swaying of the simulated wind turbine blade 2 during transportation. The swaying data can be used to determine whether the current vehicle speed is appropriate, and the vehicle speed can be controlled based on the test results. The position of the angle displacement sensor 13 on the arc frame 1 can be changed by the electric push rod 3, so that the amplitude of the swaying of the simulated wind turbine blade 2 at different positions can be detected. The dual-shaft extension synchronous cylinder 12 can adjust the position of the angle displacement sensor 13 on the arc frame 1. The controller 4 is fixed to the upper surface of the mounting bracket 5 by bolts. The controller 4 is electrically connected to the angle displacement sensor 13 and the electric push rod 3.

[0023] Working principle: When needed, the simulated wind turbine blade 2 is placed into the fixing sleeve 6, and then the screw 9 is tightened and fixed to the simulated wind turbine blade 2 through the threaded hole on the fixing sleeve 6. After fixing, the reduction motor 10 is started. The reduction motor 10 drives the mounting frame 5 to rotate, and the mounting frame 5 will drive the simulated wind turbine blade 2 to rotate horizontally, thereby changing the angle of the simulated wind turbine blade 2. The test is conducted to determine the angle at which the simulated wind turbine blade 2 will tilt. This test of the rotation angle is beneficial for optimizing the safety performance of the hydraulic control device based on the test results during the production process of hydraulic control of the lifting vehicle.

[0024] This device can also be installed on a vehicle to simulate the transportation of the blade. The angle displacement sensor 13 on the arc frame 1 will detect the amplitude of the swaying of the simulated wind turbine blade 2 during transportation. The swaying data can be used to determine whether the current vehicle speed is appropriate, and the vehicle speed can be controlled based on the test results.
