Description

Technical Field

[0001] The utility model belongs to the technical field of turning tools for wind turbines, and particularly relates to a follow-up device for a turning tool. Background Technique

[0002] The turning tool is used at the site of wind turbine blade installation and maintenance. It is necessary to lift the turning tool into the wind turbine nacelle and complete the assembly with the fan drive chain. The existing turning tools have the following problems. In case of special situations such as bad weather, all the wind turbine blades cannot be installed at the construction site, and the power supply cannot be maintained for a long time. When the power is cut off, the motor of the turning tool will automatically brake and lock the fan drive chain. Due to the influence of wind load, the wind turbine blades will swing back and forth. Therefore, the turning tool end bears the reciprocating load transmitted by the drive chain, which will have a greater impact on the service life of the turning tool motor brake and the internal gearbox of the turning tool in the long run.

[0003] For example, the Chinese patent with the publication number CN201140766Y discloses a brake disc assembly for an electric vehicle follow-up brake, which relates to the assembly of a brake disc and a dust cover in an electric vehicle follow-up brake. The brake disc assembly is formed by the interference fit combination of a brake disc and a dust cover. A dust-proof groove is formed between the outer circumferential wall of the brake disc and the inner circumferential wall of the dust cover; the bottom of the inner concave arc panel of the dust cover is connected to the lower part of the inner circle of the dust cover, the upper part of the inner concave arc panel of the dust cover is connected to the vertical arc panel of the outer circle of the dust cover, and the top of the vertical arc panel of the outer circle of the dust cover has an outward convex flange.

[0004] The following problems exist in this patent:

[0005] In the prior art documents, it is inconvenient to use in case of special situations such as bad weather. When follow-up turning is required, the transition pin shaft cannot be loosened by using the transition rotary bearing, thus reducing the follow-up function of the turning tool. Moreover, it is inconvenient to use the transition rotary bearing to protect the turning tool components in the prior art documents, thus reducing the safety and reliability of the use of the turning tool components. In view of this, we propose a follow-up device for a turning tool. Content of the Utility Model

[0006] The purpose of the utility model is to provide a follow-up device for a turning tool aiming at the above-mentioned existing technical problems, so as to achieve the effect of improving the follow-up function of the turning tool and the effect of improving the safety of using the turning tool components.

A transition slewing bearing is movably installed inside the transfer disk body. A pin hole is penetrated through the inside of the transition slewing bearing. A transition pin shaft is movably folded at one end of the pin hole.

[0008] Based on the above structure, the follow-up pin shafts assemblies and the barring are linked by the press-in bolts movably installed inside the follow-up pin shafts assemblies. Then, the follow-up pin shafts assemblies and the barring are separated by using the ejecting bolts to be movably withdrawn inside the follow-up pin shafts assemblies. When encountering special situations such as bad weather, barring follow-up can be carried out, thereby improving the convenience of barring follow-up. Then, the transition pin shaft is movably inserted into the pin hole, and then the transfer disk body and the reduction gearbox are separated by using the transition slewing bearing, which can facilitate the return movement support of the barring, thereby improving the safety and reliability of the use of barring components.

[0009] Preferably, a reduction gearbox is movably installed at one end of the transfer disk assembly. A connecting rod is installed on one side of the reduction gearbox by bearings.

[0010] Preferably, a linkage rod is installed on the bottom of the connecting rod by bearings. A connecting buckle is fixedly installed on the top of the connecting rod. A reaction arm assembly is installed on the bottom of the connecting rod by bearings.
