Description
Technical field
The utility model relates to a kind of lifting appliance, particularly a kind of lifting appliance of loaded switch.
Background technology
In the electric power overhaul process, increase (changing oil originally changes pendant-core examination into) along with load switch of transformer light maintenance project, electric power overhaul work work capacity just increases greatly, and traditional load switch of transformer suspended core method is to coordinate the workplatform of service personnel on voltage transformer top to carry out service work by 8T or 12T automobile loop wheel machine and lifting personnel, and this method is because the variation of loaded switch maintenance content exposes following problem:
1,, during operation, need on 3 and voltage transformer workplatform 3 on the ground of 6 staff.Because space on the voltage transformer workplatform is limited, more crowded on the voltage transformer workplatform, personnel have the danger of falling from voltage transformer.
2, crane firmly be difficult to control, as badly as loaded switch fuse position add that the lifting personnel overexert, will cause damage to the static contact of switch staving and the moving contact of switch fuse, cause equipment breakdown.
3, the loop wheel machine action radius is large, the accident potential that exists mistake to touch charging equipment when rotating, and because ambient noise is large, the responsible official commands difficulty again, has a strong impact on personnel and property safety in maintenance process.
Summary of the invention
technical problem to be solved in the utility model is to provide a kind of safe, high efficiency loaded switch lifting appliance, for this reason, the utility model is by the following technical solutions: it comprises base and upending frame, described upending frame comprises support and the hoisting structure that is vertically set on base one side, described support is that the montant and the cross bar that intersect vertically form, described hoisting structure comprises a removable fixed pulley and irremovable fixed pulley that is connected to the handle wheel on montant and is positioned at cross bar, handle wheel comprises the handle wheel support, pass the S. A. of handle wheel support and the rotary handle that is connected with S. A., on S. A., be wound with serving, described serving is walked around two fixed pulleys simultaneously and the fixed pulley in the outside stretches out, serving end connecting shackle.
Adopting on the basis of above technical scheme, the utility model can also be by the following technical solutions:
Described montant is the more piece setting, comprises static part and rotating element, and described handle wheel is fixed on rotating element.
Described base comprise fixing montant fixed plate and with the fixed plate one with the fixing adapter plate of loaded switch, described adapter plate is provided with some screw holes.
Described cross bar is tabular, and is provided with fixed orifice and removable fixed pulley support, and removable fixed pulley carrying sleeve is on cross bar, and removable fixed pulley support has the bolt hole corresponding with fixed orifice.
Described handle wheel support lateral surface has closing appliance, described closing appliance comprises locking disc and the snap close that is connected with the handle wheel shaft, described locking disc is circular, and locking disc week upwards is provided with the tooth of same direction of tilt, and described snap close can corresponding buckle between adjacent tooth or break away from.
Owing to having adopted the technical solution of the utility model, lifting appliance of the present utility model adopts movably pulley adjustment lifting position, and by the handle lifting of handle wheel, simple to operate, practical; Simultaneously, locking disc the safety that has guaranteed in the lifting process is set, can lock at any time lifting appliance, be difficult for landing.The utility model is simple to operate, with low cost, has extremely strong practicality, in the electric power overhaul operation, can guarantee safety and high efficiency.
