The principle of design that self-elevating tower crane is adhered in wind power equipment lifting described in the utility model is as follows:
(1) utilize the strength and stiffness of blower fan tower barrel 17 self, its intensity is that blower fan tower barrel 17 overcomes lifting torque, rough calculation is more than sufficient, rigidity is mainly that the not ability of unstability of pressure is born in tube wall part when being subject to lifting by crane pressure of blower fan tower barrel 17, its load-carrying capacity is according to equicrural triangle clasping structure form, carries out calculation and test check 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 the diametral load of balance square, six of upper and lower equicrural triangle power equate, the stress point that its leg-of-mutton stressed strong point is oil cylinder seat;
(3) the stressed character of point of equicrural triangle angle upper cylinder converts the circumference uniform distribution of tower cylinder 17 to and three tube wall faces of certain axial length are stressed, its structure is that stress point is symmetrical up and down, radial symmetry one-to-two, two minutes four, the power of a point convert to two or four lines stressed, 60 tons, 1.5MW cabin, 8 tons of arms, lift heavy center of gravity by 4 meters of the outer walls apart from tower cylinder 17, platform up and down the main friction coefficient of holding 4 meters of oil cylinder 5 support intervals, rubber 24 tightly by 0.5, the oil cylinder strong point is stressed is about 60 tons, stressed by 4 lines (bar), every stressed 15 tons;
(4) connecting column 7 and association structure is that the power of main platform is to the conversion body of tower cylinder 17 transmission, the vertical force of main platform is to be delivered to and to be connected column 7 with master slider 26 by its main runner block 25, equalizer bar 20(compresses equalizer bar 20 and to be connected column 7 be to be rigidly connected to compressing to utilize master on the head tree 9 of main platform to hold oil cylinder 5 transmission of pressures tightly), clamping frame 23 and rubber pad 24, be delivered to tower cylinder 17.
Installation, work and unloading process that self-elevating tower crane is adhered in wind power equipment lifting described in the utility model are as follows:
(1) erection of equipment: first segment tower cylinder 17 is by common crane lifting, afterwards the main platform that only remains main beam 10 after assembling is hung on chassis, integral body is moved on to the installation site of tower cylinder 17, and then the main beam 10 of 9 of head trees is installed, and completes the installation of main platform; Install auxiliary platform and with hoist cylinder 16, connect pitching oil cylinder 13, return to 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 possess the condition of lifting second section tower cylinder 17 to the middle and upper part of first segment tower cylinder 17 after; Lift by that analogy the 3rd joint tower cylinder 17, joint portion lifting fan and miscellaneous part at 2～3 joint tower cylinders 17, finally lift fan blade.Tower crane lifting (climb and decline) process is as follows: during lifting, main platform enclasp device unclamps, auxiliary platform enclasp device compresses, hoist cylinder 16 work, the main platform of lifting, reach desired location after main platform enclasp device compress, auxiliary platform unclamps, hoist cylinder 16 work, 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 approaches tower cylinder 17) facilities, platform is placed down on track chassis, arm 1 bends down unloading bar direction,-10 degree left and right connect returns to oil cylinder 15, removes pitching oil cylinder 13, and arm 1 continues nutation, before 45 degree, suspension hook 12 is put off on ground, arm 1 nutation is lifted by crane and is dismantled by crane when approaching ground; If only only remove main beam 10 for the main platform of transition, auxiliary, platform is only removed the contact part-structure that the auxiliary platform of impact exits; Make the parts transition as much as possible on the head tree 9 of main platform.
