The principle of design of wind power equipment lifting attachment self-elevating tower crane of the present invention is as follows:
(1) strength and stiffness of blower fan tower barrel 17 self are utilized, its intensity is that blower fan tower barrel 17 overcomes lifting torque, rough calculation is more than sufficient, the ability of pressure not unstability is born in tube wall local when being subject to lifting by crane pressure of rigidity mainly blower fan tower barrel 17, its load-carrying capacity is according to equicrural triangle clasping structure form, carries out calculation and test check and determine by anchor wire (bar) number of the caliber of blower fan tower barrel 17, thickness of pipe, enclasp device force transferring structure and length;
(2) circumference equicrural triangle arranges that tower cylinder 17 is stressed, the length of head tree 9 is as the connector of the two triangle beaer of the axial distance of tower cylinder 17, be combined into main bench board, a leg-of-mutton limit is as lift heavy orientation, the diametral load of the far-end angle strong point of upper triangle body and two angle strong points of lower triangle body near side (ns) forms lift heavy torque balance square, with regard to balancing the diametral load of square, six power of upper and lower equicrural triangle are equal, and namely its leg-of-mutton stressed strong point is the stress point of oil cylinder seat;
(3) the stressed property transition of point of equicrural triangle angle upper cylinder becomes three tube wall faces of the circumference uniform distribution of tower cylinder 17 and certain axial length stressed, its structure is that stress point is symmetrical up and down, radial symmetry one-to-two, two point four, namely the power of a point convert two to or four lines stressed, 60 tons, 1.5MW cabin, arm 8 tons, lift heavy center of gravity by apart from the outer wall 4 meters of tower cylinder 17, platform up and down master hold tightly oil cylinder 5 support interval 4 meters, rubber 24 friction coefficient by 0.5, the oil cylinder strong point is stressed is about 60 tons, stressed by 4 lines (bar), stressed 15 tons of every bar;
(4) connecting column 7 and association structure is the conversion body that the power of main platform is transmitted to tower cylinder 17, the vertical force of main platform to be delivered to master slider 26 by its main runner block 25 to be connected column 7, utilize the master on the head tree 9 of main platform to hold oil cylinder 5 transmission of pressure tightly and compress equalizer bar 20 and to be connected column 7 be rigidly connected to compressing equalizer bar 20(), clamping frame 23 and rubber pad 24, be namely delivered to tower cylinder 17.
The installation of wind power equipment of the present invention lifting attachment self-elevating tower crane, work and unloading process are as follows:
(1) erection of equipment: first segment tower cylinder 17 is by common crane lifting, afterwards the main platform only remaining main beam 10 after assembling is hung on chassis, the overall installation site being moved on to tower cylinder 17, then installs the main beam 10 between head tree 9, completes the installation of main platform; Install auxiliary platform and with hoist cylinder 16, connect pitching oil cylinder 13, return oil cylinder 15, hydraulic efficiency pressure system possesses service conditions; Compression, hoist cylinder 16 enter control position; Lifting appliance is installed.
(2) working process: this tower crane climbing lifts second section tower cylinder 17 after possessing the condition of lifting second section tower cylinder 17 to the middle and upper part of first segment tower cylinder 17; Lift Section of three tower cylinder 17 by that analogy, at joint portion lifting fan and the miscellaneous part of 2 ~ 3 joint tower cylinders 17, finally lift fan blade.Tower crane lifting (namely climb and decline) process is as follows: during lifting, main platform enclasp device unclamps, auxiliary platform enclasp device compresses, hoist cylinder 16 works, and is elevated main platform, and after reaching desired location, main platform enclasp device compresses, auxiliary platform unclamps, hoist cylinder 16 works, and auxiliary platform liftable, also can enter lifting state.
(3) remove: erecting equipment has lifted, arm 1 continues to face upward plumb position and declines to-4 degree left and right (suspension hook coaster is close to tower cylinder 17) facilities, platform is placed down on track chassis, arm 1 bends down unloading bar direction,-10 degree left and right connections return oil cylinder 15, and remove pitching oil cylinder 13, arm 1 continues nutation, put off on ground by suspension hook 12 before 45 degree, arm 1 nutation lifts by crane dismounting to close to during ground by crane; If be only the main platform of transition only remove main beam 10, auxiliary, the contact part-structure that the auxiliary platform of impact exits only removed by platform; Make the transition as much as possible of the parts on the head tree 9 of main platform.
