Embodiment Construction
[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0015] A self-contained power supply system for a crane, which mainly includes a crane body. The crane body includes a hoisting device. A box body lowering power generation device is arranged on the hoisting device of the crane. The power generation device is a small generator set, which is mainly used when the crane box body is lowered. , using the energy of the falling box to generate electricity. In order to store the electrical energy generated by the generating set, such as figure 1 As shown, the generator set is connected to a charging power source 1, the charging power source 1 includes an input end and an output end, the input end is connected to the generator set, and the output end is connected to a capacitor bank 2, the capacitor bank...

The invention provides a self-contained power supply system for a crane, mainly comprising a crane body which comprises a lifting device used for lifting a box body. The self-contained power supply system is characterized in that a box body descending generating device is arranged on the lifting device, and is connected with a charging module; the charging module is connected with a storage module used for storing electric energy; the storage module is connected with an inversion module used for supplying power to the external; and the charging module, the storage module and the inversion module are connected with a PLC control module. By adding the system on the crane, the energy generated by the descending of the box body is fully utilized and is converted to the electric energy to be stored, and the electric energy is applied to an electricity user such as an illuminator, an air conditioning, a telephone and the like, therefore, an engine of the crane is started only when the lifting device is used for running; and when the lifting device does not work, the engine can be closed, thereby the oil consumption is saved, and the environmental pollution is also lightened at the same time.
Description
technical field [0001] The patent of the present invention relates to the technical field of cranes, in particular to a self-contained power supply system for cranes. Background technique [0002] At present, the tire-type container gantry crane generally uses a diesel engine at a speed of 1500r / s to make a 500kW generator set supply power to the operation, lighting, and air-conditioning systems of the tire crane. However, the actual utilization rate of the loading and unloading operation of the tire-type container gantry crane is about 60%, and the other 40% is mainly occupied by the non-loading and unloading operation time. However, in order to ensure the power supply needs of the cab air conditioning, lighting and other facilities, the engine has to be kept at 1500r The speed of / s makes the high-power generator set in the running state, thus wasting a certain amount of energy consumption. [0003] The Chinese patent authorization announcement, the patent application num...
