Crane safety sliding contact line is a kind of new mobile power supply device, with its insulation, safety, high temperature resistant, anti vibration, energy-saving advantages to gradually replace the old bare iron and copper sliding contact line. Security sliding touch line by caulking smooth in the engineering plastic tube or a channel plate in the T2 copper bar or block wear conductors of aluminum as the carrier fluid, combined into a transmission pipe, with an opening groove to facilitate the collector operation catheter, and collector of high wear-resistant copper matrix graphite brush electric force directed electrical work.
Bridge crane is easy to cut off in use, sometimes sparks in the transmission conduit, serious when sliding contact line of a shooting ", caused by the collector to replace the too frequent, affecting production. To this end, Liaoning Huayuan crane crane of the production was improved as follows:
(1) increased the collector brush chamfered, and polished);
(2) increased two of the collector relative brush spring strength, elastic, ensure the spring freely;
(3) deepening. Strengthening the spring seat set in electric appliance, ensure that the brush recovery spring in the work not easy "series";
(4) the two security sliding touch line connection block to ensure smooth transition chamfer, collector. At the same time, to ensure the safety and normal use of sliding contact line, operation, repair specification for hydraulic driving workers periodic maintenance, regular inspection is also essential.
