　　Improvement Scheme for Crane Safety Sliding Contact Line

　　Safety Sliding Contact Line is a new type of mobile power supply device, which gradually replaces the old exposed angle iron and copper bar sliding contact lines due to its superior performance such as insulation, safety, temperature resistance, vibration resistance, and energy saving. The safety sliding contact line uses smooth and flat T2 copper bars embedded in engineering plastic tubes or trough plates, or aluminum profiles with wear-resistant conductors embedded, as current-carrying conductors, combined into a power transmission conduit. There is an open slot at the bottom of the conduit to allow the current collector to run, and the high wear-resistant copper-based graphite brush of the current collector guides the power to the working electrical equipment.

　　Bridge cranes are prone to power failure during use, and sometimes sparks are generated inside the power transmission conduit. In severe cases, the sliding contact line may "explode" at a certain point, causing frequent replacement of current collectors and affecting production. To this end, the following improvements have been made to the crane safety sliding contact line:

　　(1) Increase the chamfer of the current collector brush and polish it smooth;

　　(2) Increase the spring strength and elasticity between two opposite brushes of the current collector to ensure the spring recovers freely;

　　(3) Deepen and reinforce the spring seat in the current collector to ensure that the recovery spring of the brush is not easy to "displace" during work;

　　(4) The connecting block at the joint of two sections of the safety sliding contact line should have a chamfer to ensure smooth transition of the current collector. At the same time, to ensure the normal use of the safety sliding contact line, standardized operation by crane operators, regular maintenance by maintenance workers, and regular inspections are also essential.
