Fan yaw copper sleeve replacement tool

Abstract

The invention discloses a fan yaw copper sleeve replacement tool. The fan yaw copper sleeve replacement tool comprises a tool base; the tool base is provided with a lubricating oil groove, an air pressure groove and a copper sleeve pulling hole; a spring airbag is fixedly mounted in the air pressure groove; the bottom of the air pressure groove communicates with the lubricating oil groove throughan air way; an extrusion base and an oil injecting base are fixedly mounted at the upper and lower ends of an extrusion lifting rod; multiple oil injecting holes are formed around the oil injecting base; a fixed base movably sleeves the upper part of a lifting lead screw; lifting teeth on two sides are connected with a planet speed reducing gear; and an inner ring of the planet speed reducing gearis engaged with a one-way rotating wheel jaw. The fan yaw copper sleeve replacement tool can easily pull out a copper sleeve from a fan copper sleeve mounting base without needing external auxiliarylifting devices, can add lubricating oil around the fan copper sleeve mounting base in the copper sleeve pulling process, reduces the friction force between the fan copper sleeve mounting base and thecopper sleeve, improves the pulling success rate, and saves both time and labors.

Description

technical field [0001] The invention relates to the technical field of fan copper sleeve replacement devices, in particular to a fan yaw copper sleeve replacement tool. Background technique [0002] The yaw brake of the Envision wind turbine adopts the copper sleeve damping type, and the brake damping is provided by pre-tightening the copper sleeve bolts, but the damping state needs to be checked regularly during maintenance. This inspection requires the copper sleeve bolts to be taken out, but due to the influence of space, The wrench cannot be used smoothly, and the replacement process is time-consuming and laborious, and the process is relatively cumbersome. [0003] In the prior art, the application number is "CN201520530122.1", a hydraulic device for dismounting TRT taper pins, including a hydraulic system and a dismounting system; Hand pumps and bypass valves connected in parallel with each other by changing joints, hollow oil cylinders connected with quick-change joi...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned hydraulic device for dismounting the TRT conical pin still has obvious defects during use: 1. The above-mentioned device requires a hydraulic system to provide pressure for the oil cylinder to pull out the conical pin, although it makes up for the laborious shortcomings of the traditional replacement method , but in the absence of an external hydraulic system, the above-mentioned device cannot work normally, thus limiting the working environment of the hydraulic device for removing the TRT taper pin; 2. The above-mentioned device can only provide upward traction to pull out the object, but the replacement process The inside of the copper sleeve is often rusted and cannot be easily pulled out. The above-mentioned forced pull-out method may cause the traction tap to break and increase the difficulty of replacement.
