Crane Sliding Contact Line Yangzhou Darui
Darui Electric recommends
Sliding contact lines are mainly used in various lifting and transport machinery, production lines, and other facilities and places that require mobile power supply, such as cranes, loading and unloading bridges, electric hoists, three-dimensional warehouses, amusement equipment, air conditioning testing lines, etc. They are widely applied in many industries including lifting and transport, electric power, shipbuilding,ports, metallurgy, mining, water plants, environmental protection, chemical industry, home appliances, automobiles, clothing, tobacco and alcohol, amusement, and many other sectors.
Safe sliding contact line is a new type of mobile power supply device. With its superior performance such as insulation, safety, temperature resistance, vibration resistance, and energy saving, it gradually replaces the old exposed angle iron and copper bar sliding contact lines. The safe sliding contact line consists of smooth and flat T2 copper bars or aluminum profiles embedded with wear-resistant conductors, which are filled inengineeringplastictubes or trough plates, 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 conducts electricity to the working equipment. The use of safe sliding contact lines brings safety to the workshop, but it also has disadvantages. Bridge cranes are prone to power failure during use, sometimes sparks are generated inside the power transmission conduit, and in severe cases, the sliding contact line "explodes" at a certain point, causing frequent replacement of current collectors and affecting production. To this end, the following improvements have been made: (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 springrecoversfreely; (3) Deepen and reinforce the spring seat in the current collector to ensure that the recovery spring of the brush does not easily "displace" during work; (4) The connecting block at the joint of two sections of safe 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 safe sliding contact lines, standardized operation by crane operators, regular maintenance by maintenance workers, and regular inspections are also essential.
