Abstract

A hoisting device for replacement of a transformer cooling fan comprises a base seat, wherein the lower end of the base seat is provided with idler wheels, the upper end of the base seat is provided with a supporting frame, a cantilever is fixed at the upper end of the supporting frame, the cantilever is provided with a group of fixed pulleys, the middle of the supporting frame is provided with a motor, a rotation shaft of the motor is provided with a coiling barrel, a steel wire rope winds the coiling barrel, one end of the steel wire rope is fixed with the coiling barrel, the other end of the steel wire rope winds the fixed pulleys and a movable pulley and then is fixed on the cantilever, and the moveable pulley is provided with a lifting hook. A lifting rope is tied to the transformer cooling fan, the lifting hook grapples the lifting rope, bolts used to fix the cooling fan are detached, the motor is started, the cooling fan is lifted, the supporting frame is rotated, and the cooling fan can be transferred to the ground. Similarly, the hoisting device lifts a new cooling fan and conveys the cooling fan to the installation position, and then the cooling fan can be installed. The hoisting device for the replacement of the transformer cooling fan well resolves the problems that in the process of the replacement of the cooling fan, labor input is large, time consumption of working is long, and safety hidden dangers exist in manual transport.

Description

The voltage transformer cooling fan is changed lifting appliance
Technical field
The utility model relates to a kind of lifting appliance, a kind of lifting appliance that uses when specifically power supply department is changed the voltage transformer cooling fan.
Background technology
In the long-time running of power supply department main transformer, cause the reasons such as phase-deficient operation of motor water inlet or motor, machine winding is burnt by rainproof cover, the connection box poor sealing of cooling fan on it.Under the situation that burning appears in cooling fan motor, require the plant maintenance personnel under the condition of not stopping main transformer, it to be changed.At present, when the cooling fan of main transformer is changed, rely on manpower that it is carried fully; The replacing work flow of traditional voltage transformer cooling fan is: prepare manpower holder Fufeng fan, dismounting fan bolt of rear end plate before the work; Manpower lifts fan, and carrying fault fan is to ground, and the new fan of manpower transport is to the installation site; Manpower holder Fufeng fan, and correction position are installed the fan bolt of rear end plate.
It is thus clear that the problem that relies on manpower transport's cooling fan to exist fully is: the human input that 1, more changes jobs is big, 2, the length consuming time of working, 3, collide with in a dead lift process injuredly easily, potential safety hazard is arranged.
The utility model content
The purpose of the utility model is to provide a kind of voltage transformer cooling fan and changes lifting appliance, and this lifting appliance can be realized lifting to the voltage transformer cooling fan, to replace a dead lift, has promptly saved the replacing time, reduces human cost simultaneously.
For realizing above-mentioned purpose, the utility model adopts following scheme: the voltage transformer cooling fan is changed lifting appliance, and it has a base; Roller, upper end that the lower end of base is equipped with more than three are equipped with support, and the support upper end is fixed with cantilever, and one group of fixed pulley is housed on the cantilever; The middle part of support is installed and is provided with a motor; In the rotating shaft of motor reel is housed, is wound with steel rope on the reel, an end and the reel of steel rope are fixed; The other end of steel rope is fixed on the cantilever after walking around each fixed pulley and a movable pulley, is connected with suspension hook on the movable pulley.
Visible by such scheme, the good lifting rope of bolt on the cooling fan of voltage transformer hooks lifting rope with suspension hook earlier; Remove the fixedly bolt of cooling fan then, starter motor is sling cooling fan; Swinging mounting can be transferred to ground with it, and is same; By this lifting appliance new cooling fan is sling again, and handling can be installed cooling fan to the installation site.
The utility model rational in infrastructure, dependable performance, the problem that it has solved effectively, and cooling fan changes jobs more that human input is big, work length consuming time and a dead lift have potential safety hazard has excellent popularization and is worth.
