Said structure, when tower crane needs work, an end of hoisting wirerope not being installed suspension hook is connected on the elevator jacking equipment of automobile, make suspension hook can be on the different positions in vertical direction under the effect of elevator jacking equipment, by adjusting walking dolly suspension hook is on the different positions in the horizontal direction, with regard to realizing the optional position on the vertical wind power generator is detected and keeped in repair like this.Tower crane is when work, because second pulley is installed on the equilibrium arm, first pulley is installed on the driving dolly, and walking dolly is located on the guide rail of arm, and hoisting wirerope is located on first pulley and second pulley, when carrying weight on the suspension hook and moving, the power of being born on first pulley and second pulley is equal substantially, and therefore, the power on arm and the equilibrium arm is also equal substantially, like this, just need clump weight be set on equilibrium arm, compared with prior art, alleviate the weight of tower crane, thereby improved the vertical wind power generator stability of structure, and, owing to not needing clump weight to reduce the cost of tower crane, simultaneously, also safety when using tower crane, simple in structure; Structure of the present utility model, because the elevator jacking equipment is mounted on the automobile, when needs are installed and are keeped in repair vertical wind power generator, automobile is left for the scene, when when not required, promptly can drive from the scene, like this, the elevator jacking equipment need be installed on cooresponding tower crane on every vertical wind power generator, many vertical wind power generators can a shared automobile that the elevator jacking equipment is installed, and therefore, greatly reduces the cost of tower crane, also alleviated the weight that is compressed on the aerogenerator king-post, and,, can move at any time because the elevator jacking equipment is installed on the automobile, therefore, change and keep in repair the elevator jacking equipment conveniently.
As improvement, the diameter of described wind generator tower capital end is less than the diameter of bottom; Described revolution pylon comprises supporting tower frame and bearing; The outer ring of bearing is connected with supporting tower frame, and bearing cone is set on the wind generator tower capital end.
The diameter of wind generator tower capital end needs the diameter of bearing little less than the diameter of bottom, and therefore, cost is low.
As improvement, described arm is provided with first drag-line away from an end of aerogenerator king-post; Equilibrium arm is provided with second drag-line away from an end of aerogenerator king-post.
When tower crane is worked, first drag-line and second drag-line are fixed on the ground, like this, can prevent arm and equilibrium arm generation beat, improve the stability and the intensity of tower crane.
As improvement, described revolution pylon protrudes upward arm and equilibrium arm; Be connected with the arm drag-line between the top of revolution pylon and the arm, be connected with the equilibrium arm drag-line between revolution pylon top and the equilibrium arm.This structure can prevent arm and equilibrium arm generation beat, has further improved the stability and the intensity of tower crane.
