Detailed Description

Examples

The utility model relates to a aerogenerator pincers assembly and disassembly tools that drifts, including clamp tray 1, jack 4, hydraulic oil pump 8, chassis 5 and at least a set of telescoping device, link to each other through the telescoping device between clamp tray 1 and the chassis 5, wherein clamp tray 1 and chassis 5 on be equipped with first tie point 2 and second tie point 6 respectively, the clamp that drifts passes through 2 fixed mounting of first tie point on the clamp layer board, 6 fixed mounting of second tie point are passed through to 4 one end of jack on chassis 5, and the other end links to each other with the telescoping device, and jack 4 still is connected with hydraulic oil pump 8, and accessible hydraulic oil pump 8 and jack 4 drive the telescoping device and rise or reduce. The telescopic device is a telescopic frame 3, and the telescopic frame 3 is formed by cross connection of telescopic rods. The expansion bracket 3 is three groups, and the central axes of the three groups of expansion brackets 3 are all positioned in the same vertical plane. The hydraulic oil pump 8 is connected with the jack 4 through a hydraulic oil pipe 7. The chassis 5 is also provided with an anti-skid rubber sleeve. And the yaw clamp is fixedly connected with the clamp supporting plate through a bolt.

In the embodiment, the clamp tray 1 is a cube with the specification of 450mm, the first connecting point 2 is arranged on the surface of the clamp tray 1 in a diagonal manner, the first connecting point 2 is provided with a fixing pin, one end of the fixing pin is connected with the clamp tray 1, and the other end of the fixing pin corresponds to a screw hole on the yaw clamp; the telescopic bracket 3 is provided with three groups in this embodiment, the security that clamp tray 1 risees or descends has been guaranteed, make whole device can keep certain stability when using, the rising or the reduction of telescopic bracket 3 are controlled through jack 4 that sets up, jack 4 preferred adoption is electronic in this embodiment, but not only is limited to the electric mode, also can be manual, select according to actual conditions, hydraulic oil pump 8 realizes going up and down for jack 4 provides power, the anti-skidding gum cover that sets up on the chassis 5 in this embodiment can guarantee the stability of jack 4.

The utility model has the following using steps that (1) the fan is stopped; (2) disconnecting the power supply of the fan hydraulic system and releasing pressure (3) to drain residual oil of the yaw clamp and the oil pipe to the full extent so as to dismantle the oil pipe; (4) the utility model is assembled on the yawing platform; (5) a spanner is used for detaching the screws corresponding to the fixing pins of the clamp pallet 1; (6) connecting a hydraulic oil pump 8, and lifting the clamp tray 1 until the fixing pin is inserted into the corresponding screw hole of the yaw clamp; (7) after the clamp tray 1 holds the clamp, connecting screws of the rest yaw clamps can be detached by using a tool; (8) after all the screws are removed, the telescopic frame 3 is slowly descended by controlling the hydraulic oil pump 8 until the screws are lowest, so that the yaw clamp is removed completely (reverse sequential operation is required during installation).

The utility model has convenient transportation and simple use, and the yaw clamp is fixed by the fixing pin when in use, thereby preventing the yaw clamp from being damaged in the disassembly process; the jack that sets up rises and excessively reduces driftage clamp, has reduced the manual work, has guaranteed operation safety.
