Improvement of Overhead Crane Safety Sliding Contact Line
Improvement of Overhead Crane Safety Sliding Contact Line
Crane safety sliding contact line is a new type of mobile power supply device, with its insulation, safety, temperature resistance, vibration resistance, energy saving and other superior performance gradually replaced the old bare angle iron and copper rows of sliding contact line.
Bridge crane in use is easy to power outage, sometimes in the transmission conduit sparks, when the seriousness of the sliding contact line a discharge", resulting in collector replacement is too frequent, affecting production. To this end, the following improvements:
(1) Increase the collector brush chamfer, and grinding smooth;
(2) increase the collector two relative brush spring strength, elasticity, to ensure that the spring recovery freely;
(3) Deepen. Reinforce the spring seat in the collector to ensure that the recovery spring of the brush is not easy to "crosstalk" in the work;
(4) Two sections of safety sliding contact line connection connection block should have chamfer, to ensure that the collector smooth transition. At the same time, in order to ensure the normal use of the safety sliding contact line, the standard operation of the line workers, maintenance workers of regular maintenance, regular inspection is also indispensable.
