Description
Technical field
The utility model relates to a kind of trolley automatic electricity taking device, particularly relates to the current-collector in a kind of trolley automatic electricity taking device.
Background technology
At present, the general hoisting machinery (a common name bridge) of the each Port container terminal operations in the world mainly contains two kinds, one is track type container large scale crane, be Rail-mounted gantry crane, be abbreviated as RMG, another kind is rubbertyred container gantry crane, and rubber-tyred container gantry crane, is abbreviated as RTG.RMG adopts mains-supplied, and the low but action of energy consumption is limit by track between each stockyard, to change, and RTG carries the power supply of diesel power generation unit, and transition is flexible but energy consumption high pollution is large.At present, there is having concurrently the RTG device of the little advantage of the low pollution of RMG energy consumption, this RTG only uses the power supply of diesel power generation unit in the time of transition, operate from utility grid power taking by trolley in the venue, it is electric rubber-tyred container gantry, electrical rubber-tyred container gantry crane, is abbreviated as ERTG.ERTG has also kept the advantage of the flexible transition of RTG in having improved energy utilization patterns, therefore uses now increasingly extensive.
The at present trolley automatic electricity taking device of ERTG, normally arranges power taking support the runway of RTG is other, is provided with and the trolley of city's electric connection on power taking support, then also needs to use a current-collecting cart moving together with RTG.Dolly is electrically connected with RTG, and dolly is provided with current-collector, and current-collector end is provided with carbon brush, when power taking, current-collecting cart is installed on power taking support, and carbon brush is connected with trolley, thereby realize, the electricity on trolley is got on RTG.In this process the technical issues that need to address be as with dolly is installed on power taking support and realizes being synchronized with the movement of dolly and RTG.
Traditional mode is to pass through manual work, current-collecting cart is arranged on power taking support, then manually the plug of dolly is inserted on RTG both are electrically connected, realize and powering to RTG to the method for trolley by the artificial haulage cable dolly of plugging into again, this manual work mode not only wastes time and energy, inefficiency, and meet rainy weather plug plug, and also having the danger of getting an electric shock, fail safe is low.
Therefore occurred now that some mount and dismount the structure in trolley by power taking dolly automatically, the automatic electricity taking device for rubbertyred container gantry crane as disclosed in Chinese patent CN202124432U, comprise the connecting device of being located at the other power taking support of gantry runway, current-collecting cart, being connected with current-collecting cart, one end of this connecting device is fixed on tyre crane, the other end connects current-collecting cart, and by the flexible of connecting device with move up and down, current-collecting cart is connected with power taking support and then is tyre crane power taking.
The front end of the current-collecting cart in this automatic electricity taking device is provided with carbon brush, is all to be conventionally two row arranged side by side to arrange, and each row all has multiple overlapping carbon brush, carbon brush and trolley contact electricity getting.Carbon brush below is provided with cable and is communicated to tyre crane.Such carbon brush shared location comparison of generally arranging is large, therefore, has caused the increase of the volume of whole current-collecting cart, and then has increased the difficulty of processing of current-collecting cart and connecting device.
And the mobility of such carbon brush structure carbon brush is lower, carbon brush can not adapt to trolley and have the adjustment of certain scope, while causing power taking, carbon brush must contact with trolley well, therefore when encountering in tyre crane running in the situation that vibration or wind are larger, easily make carbon brush and trolley unclamp, cause powering bad.
