Self-climbing wind power maintenance crane mainly replaces the expensive fan large maintenance lifting equipment - crawler crane. It combines self-climbing hydraulic lifting platform with high-hoisting folding crane to complete the maintenance of wind power equipment.
Yuntian company research and development autonomously climbing crane for wind power station maintenance mainly consists of four parts:
adaptive noninvasive clamping system, high lifting climbing folding hoisting system, hydraulic system and electric control system.
adaptive noninvasive clamping system through four units consists of special polymer materials in contact with wind power tower drum, arms device in increasing the friction between the tower drum at the same time will damage to a minimum, four groups while working arms leg 221 groups by telescopic cylinder climb the whole process.
High hoisting system is mainly composed of hoist lifting folding, slewing mechanism, luffing device of telescopic, etc, which can realize the vertical and horizontal direction, in slewing mechanism, luffing device of telescopic crane comprehensive work at the same time also make the whole machine is convenient for transportation.
Adopts two sets of variable proportional control hydraulic system not only improves the security of the whole hydraulic system, also reduce the energy consumption of equipment and safety concerns, which guarantees the reliable operation of the whole equipment.
At present, the products have been declared china national 4 utility model patents, 1 china national invention patents.
From climbing wind power application of crane maintenance, will significantly shorten the maintenance time, reduce the maintenance cost, to subvert the traditional wind power maintenance way, will have a huge on the vigorous development of the global wind power industry, the positive impact.
1.Flexible operation, stable performance, rapid maintenance
2.It is dragged by automobile with good mobility, and it doesn’t need auxiliary installation.
3.New Type high polymer material is used, so it won’t do harm to draught fan tower tube.
4.It uses zero damage self-adaption climbing model, and it has self-jacking climbing equipment which can achieve auotomatic lifting.
5.Crane lifting is stable without any shock and it is able to stretch, fold, turn, lift auotomatically.
6.It has more than 30 kinds of protection devices such as overspeed, overload, limit, mechanical hydraulic interlock, correction, pressure detection, overcurrent, etc.
7.Combine the electrical control with hydraulic system.
