The device comprises a back plate (2), the center of the back plate is in threaded connection with a center screw rod (3), transverse holes (21) are formed in the two sides of the back plate, fixing screw rods (11) are welded to shells of the two hydraulic jacks, and the fixing screw rods penetrate through the transverse holes of the back plate to be in threaded connection with nuts (4). The position feedback device is used for the position feedback of the straight-stroke pneumatic actuating mechanism switch.

Description

Technical Field

[0001] The utility model relates to a disassembly tooling for a high-speed shafting of a hydraulic top disc gearbox. Background Art

[0002] The gearbox of a wind turbine is a gearbox specifically applied in the field of wind power generation. Its main function is to convert the high torque and low speed of the wind power impeller into the low torque and high speed on the side of the wind power generator to meet the working requirements of the generator. The wind power industry in China has developed relatively early, and there is a large stock of old double-fed wind turbines below 2 MW. For such gearboxes, high-speed shaft failures can basically be replaced on the tower. In the past, the disassembly of the high-speed shafting was mostly carried out by manual shaft pulling, which was inefficient, laborious, and had a high risk.

[0003] Therefore, it is necessary to provide a high-speed shafting disassembly device to solve the above technical problems. Content of the Utility Model

[0004] The utility model is to solve the above existing technical problems and provides a disassembly tooling for a high-speed shafting of a hydraulic top disc gearbox.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A disassembly tooling for a high-speed shafting of a hydraulic top disc gearbox, which comprises a back plate. A central screw is threadedly connected to the center of the back plate. Transverse holes are opened on both sides of the back plate. Fixed screws are welded to the shells of two hydraulic jacks. The fixed screws pass through the transverse holes of the back plate and are threadedly connected to nuts.

[0007] For the disassembly tooling for a high-speed shafting of a hydraulic top disc gearbox, the back plate is a rectangular plate, and a screw hole is opened at its center.

[0008] For the disassembly tooling for a high-speed shafting of a hydraulic top disc gearbox, the oil inlet pipes of the two hydraulic jacks are both connected to the oil outlet end of a distributor. The oil inlet end of the distributor is communicated with a manual pump through an oil outlet pipe. Advantageous Effects

[0009] 1. When the utility model disassembles the high-speed shaft, the central screw is used to closely fit the perforated back plate with the end face of the high-speed shaft. The central screw is tightened. Two hydraulic jacks are respectively installed into the transverse holes on both sides of the perforated back plate. The widths of the two hydraulic jacks are adjusted to appropriate positions so that the telescopic heads of the jacks can reliably top against the gearbox to the box body. The nuts at the bottoms of the two hydraulic jacks are tightened. Thus, the device installation is completed. The hand pump is slowly pressurized to observe the movement of the high-speed shafting.

[0010] 2. The utility model has a simple structure and can quickly realize the disassembly of the high-speed shaft of the gearbox.

[0011] 3. The bottom of the hydraulic jack of the present utility model is welded with a fixed screw for installation in the transverse hole of the back plate, and by adjusting the width of the two hydraulic jacks, it is applicable to gearboxes of various types. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Refer to Figure 1 - Figure 2 , a disassembly tool for the high-speed shaft system of a hydraulic top plate gearbox, which comprises a back plate 2. A center screw 3 is threadedly connected to the center of the back plate. One of the center screws is a screw for cooperating with the threaded hole of the high-speed shaft to fix the perforated back plate on the high-speed shaft. Transverse holes 21 are provided on both sides of the back plate. Fixed screws 11 are welded on the shells of the two hydraulic jacks. The fixed screws pass through the transverse holes of the back plate and are threadedly connected with nuts 4.

[0017] The back plate is a rectangular plate, and a screw hole 22 is provided at its center.

[0018] The oil inlet pipes 5 of the two hydraulic jacks are both connected to the oil outlet end of the distributor 6, and the oil inlet end of the distributor is communicated with the manual pump 8 through an oil outlet pipe 7.

[0019] The two hydraulic jacks are equipped with a single manual pump. By manually pressing the manual pump, the hydraulic oil will enter the distributor through the oil outlet pipe, and then the hydraulic oil will enter the hydraulic jacks respectively through the two oil outlet pipes to realize the synchronous action of the two hydraulic jacks.

[0020] Working principle: When disassembling the high-speed shaft, use the center screw to closely fit the perforated back plate with the end face of the high-speed shaft, tighten the center screw, install the two hydraulic jacks into the transverse holes on both sides of the perforated back plate respectively, adjust the width of the two hydraulic jacks to a suitable position, so that the telescopic heads of the jacks can reliably press against the gearbox to the box body, and tighten the nuts at the bottoms of the two hydraulic jacks. Thus, the device installation is completed. Slowly press the manual pump and observe the movement of the high-speed shaft system.
