Description
Technical Field
The utility model relates to the field of wind power gear boxes, in particular to a portal frame tool for maintenance on a wind power gear box tower.
Background
With the development of the wind power industry, the service life of the wind power gear box is longer and longer, and the conditions of maintenance and repair of the wind power gear box on a tower are more and more common. When the gearbox is maintained on the tower, a portal frame tool is often required to be built in the engine room according to the damage condition of the gearbox and the limitation of the space in the engine room, the gearbox is hung by means of the portal frame tool, and then the gearbox is opened and relevant maintenance work is carried out. As the position of the cabin base for installing the portal frame tool upright post in the cabin is generally a non-processing surface, the size error is relatively large. When the portal frame tooling is built, the situation that one or more upright posts of the portal frame tooling cannot be well attached to the mounting surface of the cabin base often occurs. If the upright posts cannot be well attached to the mounting surface in the engine room, when the portal frame is used for hanging the gear box, the parts such as the cross beam of the portal frame tool deform under the action of the weight of the gear box until all the upright posts of the portal frame tool are attached to the base of the engine room. Or when the portal frame tooling is built, if on-site operators find that all the portal frame tooling upright posts are not adhered to the cabin base, parts such as gaskets, backing plates and the like are practically matched on site, the parts are padded at the position where the cabin base and the portal frame upright post base are in a gap, the gap between the portal frame tooling and the cabin base is eliminated, and then subsequent maintenance operation and the like are performed.
At present, in the work of using portal frame frock to carry out on-tower maintenance to wind-powered electricity generation gear box, when building portal frame frock, if appear portal frame frock one or more stand can not be fine with the condition that cabin base installs face position is laminated mutually:
if the clearance between the bottom surface of the upright post and the cabin base is smaller, the upright post and the cabin base are generally tied on a portal frame tool by using a hanging belt and hang the gearbox. The hanging belt is slowly tightened, and the portal frame tool beam and other parts deform under the action of the weight of the gear box, so that the upright post which is not attached to the cabin is sunk and is attached to the cabin base, and the stability of the upright post support of the portal frame tool in subsequent use is ensured.
The disadvantages of this approach are:
1) The hanging belt is tied on the portal frame tool to hang the gear box and deform the portal frame under the action of gravity of the gear box, so that the portal frame tool can incline and bear extra force, and the damage risk and construction safety risk of the portal frame tool are increased;
2) When force is applied to deform the portal frame tool, and the upright post of the portal frame tool is tightly attached to the cabin base, if the applied force is reduced or cancelled in the subsequent construction operation process, the portal frame tool can be recovered, and the conditions such as bouncing of the tool are easily caused when the deformation is recovered too fast, so that the safety risk is increased;
if the stand column and the cabin gap are larger, parts such as gaskets and backing plates are generally arranged between the bottom surface of the stand column and the cabin base according to the conditions of the site, the stand column is padded up, and the gap is eliminated, so that when the portal frame tool is used, all stand columns of the portal frame tool can be attached to the cabin base, and the stability of stand column support of the portal frame tool when the portal frame tool is used is ensured.
The disadvantages of this approach are:
the portal frame tool is built on site, gaps are found between the bottom surfaces of the upright posts and the cabin base, when gaskets and cushion blocks are actually matched, site conditions are limited, operation is inconvenient, time consumption is long, construction time is prolonged, and stability is unstable.
