Adopt the usual manner hanging device as follows:
(1) crawler crane: 1 on CC2800 type, 1000 tons of the biggest lifting capacities, 13 meters of maximum sling heights;
(2) rubber tired crane: 2 on QUY50 type, 1 on QUY100 type, 1 on QUY200 type;
(3) rolling cart: 2.
The unit lifting is divided into three workshop sections and carries out:
First workshop section: lifting first segment tower tube, use 1 QUY200 and the cooperation of 1 QUY50 rubber tired crane to finish;
Second workshop section: lift second and third joint tower tube, use 1 CC2800 crawler crane and the cooperation of 1 QUY50 rubber tired crane to finish;
The 3rd workshop section: lift the 4th joint tower tube, cabin, impeller (wheel hub and blade), use 1 CC2800 crawler crane and the cooperation of 1 QUY100 rubber tired crane to finish.A 50MW wind energy turbine set installation phase needs 18 months.How reducing equipment cost and cost of installation is to make the wind-power electricity generation industry move towards the place of the key in market.When this type of problem occurred, once the someone utilized bionic principle to design and manufacture fixedly tower crane lifting mechanism of double-deck jaw type, was the patent application of CN2306981 as publication number.But such design just improves at performance of hoisting crane own and structure, and the overall process of tower tube lifting is simplified, and still needs further improvement.
Summary of the invention
At existing tower tube hoisting process complicated operation, and problems such as big, the heavy dismounting delivery of the auxiliary use, the work capacity that need many heavy lifts and corollary equipment difficulty, the utility model provides a kind of wind power generation climbing hoisting crane, it can replace large-scale crawler belt lifting operation car, both saved time, saving of labor, province personnel, province's expense, low to environmental requirement, degree of automation height, energy-saving and environmental protection, safety, reliable, danger is little, the place operating environment is good; Be convenient to dismounting and transportation, be not subjected to the restriction of maximum sling height, operating efficiency is higher.
The technical scheme that its technical matters that solves the utility model adopts is: wind power generation climbing hoisting crane, be to constitute by the pulley suspension hook that machine is done, upper clamp, lower clamp, Hydraulic jip and hinge rope connect, upper/lower terminal has been installed sprocket wheel in the chamber that machine is done, and with the ring chain connection that is meshed.The caliper of lower clamp is fixed in machine does the lower end, and the caliper running-fit of upper clamp is set on the dried outer wall of machine and the interior seat of caliper has ratchet to be meshed with chain; Upper clamp has the jaw that is driven by hydraulic fluid tank, and lower clamp has the jaw that is driven by hydraulic fluid tank.Wind power generation climbing hoisting crane is to be support with the barrel mast that aerogenerator has installed, utilize and embrace the rising of pincers edge barrel mast, jaw by upper and lower armful of pincers is locked at the tapered drum outer surface of column, lifts next joint barrel mast or miscellaneous part by Hydraulic jip, finishes work such as lifting, lifting.Afterwards, be back to the special-purpose carrier loader in ground by embracing the pincers jaw.Maneuvering system of this equipment and propulsion source all are arranged on the special-purpose carrier loader, are connected with the hoisting crane that climbs by cable, connection terminal and winder, realize that power provides and controllable function.
As further improvement of the utility model, main each other, the follower of two chain wheel set up and down.
As further improvement of the utility model, the jaw closed form separately of upper clamp and lower clamp all is to clamp mutually tightly with barrel mast.
As further improvement of the utility model, upper clamp is provided with 1～3 jaw of upper and lower arrangement.
The beneficial effect that the utility model produces is: can be widely used in Large-scale Wind Turbines, as the lifting of parts such as tower tube, cabin, wind wheel wheel hub, and the operating mode similarly lifting of other equipment with it, be applicable to the lifting operation of high-altitude and superaltitude heavy wares; Not limited by maximum height of lift; Not limited by the place, can be on level land, hillside, sea lifting operation; But electromechanical, degree of automation height ground control, in light weight, easy accessibility, be convenient to the transition transportation; The operating efficiency height.
