Description

Auxiliary device for mounting bolts of yaw brake of wind generating set

Technical Field

The utility model belongs to the technical field of wind power generation, concretely relates to wind generating set driftage stopper bolt installation frock.

Background

At present, large-scale wind generating sets track wind direction changes through active yawing, when the orientation of the wind generating sets is consistent with the incoming flow wind direction, the wind generating sets stop yawing, and a yawing brake brakes. With the upsizing of the wind turbine generator, the number of yaw brakes is increased.

The yaw brake needs a large number of bolts to be fixed on a cabin seat, and for example, a 4MW unit is designed with 10 yaw brakes and 120 mounting bolts. When the installation is carried out in a workshop, an installer needs to use a torque wrench to continuously carry out the tightening operation of pre-tightening, initial tightening and final tightening on the bolt. The whole process is time-consuming and labor-consuming, and the operation mode of cyclic reciprocation easily causes fatigue of operators, which is not favorable for the quality control of the assembly process. Meanwhile, potential safety hazards exist when the position of the electric wrench is adjusted by an installer, and personal injury is easily caused.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 4, the auxiliary device for installing the yaw brake bolt of the wind generating set comprises an arc-shaped support 1, a sliding block 2 and a spring balancer 3, wherein the arc-shaped support 1 is installed on a cabin seat 5, and the sliding block 2 is installed on an arc-shaped track of the arc-shaped support 1 in a sliding manner; an electric wrench 4 for installing a yaw brake bolt 6 is hung on the balancer through a sling of the spring balancer 3, and a hook at the top of the spring balancer 3 is connected with a lifting lug on the sliding block 2, so that the electric wrench 4 can move through the arc-shaped bracket 1.

Further, the arc-shaped support comprises an arc-shaped support welding assembly 1-1, a stop bolt 1-2 and a stop nut 1-3, the arc-shaped support welding assembly 1-1 comprises an installation bottom plate, a circular vertical rod and an arc-shaped rail, the installation bottom plate is installed on an installation hole position reserved in the cabin seat, the cylindrical vertical rod is fixed on the installation bottom plate, the arc-shaped rail is fixed at the upper end of the circular vertical rod, and the stop bolt 1-2 and the stop nut 1-3 are arranged at two ends of the arc-shaped rail.

The arc-shaped rail is preferably formed by bending H-shaped steel or I-shaped steel for convenient processing and production.

Preferably, through holes are formed in two ends of the arc-shaped track and used for installing stop bolts 1-2 and stop nuts 1-3 to prevent the sliding block 2 from falling off from the two ends of the track.
