Abstract

Disclosed is a special pantograph for ports, which mainly comprises an under frame, a lower jib arm, an upper jib arm, a pull rod, a balance rod, a pantograph bow and a control part which are connected together; the invention is used for supplying power for large hoists in port container pier; when the invention is mounted on a large portal jib crane, the reliability of electric power (energy source) acquisition is ensured in the continuous moving process of the large jib crane, so the large jib crane is ensured to operate normally, and the connection problem found between a fixed power supply and a moving jib crane is solved; the invention is mainly applicable to large mobile equipments in ports for acquiring power and driving the equipments to operate; the special pantograph is also applicable to various rail mobile equipments and railless mobile equipments with small motion quantity, which take electric power as energy source. The efficiency of the special pantograph reaches more than 95%; meanwhile, no electric power is consumed when the jib crane is not in operation mode; the special pantograph is maintenance free in use process; the special pantograph is replaced when the pantograph has fault; the replacement is finished in 20 minutes.

Description

technical field [0001] The invention belongs to tracked mobile equipment using electric power as energy source and trackless mobile equipment for a small amount of movement, in particular to a special port pantograph for an oil-to-electricity project. Background technique [0002] At present, container terminals in my country and abroad all use a large diesel generator installed on the door crane as the power source. Once the diesel generator is started, it will work continuously, regardless of whether the door crane is working or not, and energy waste is very large. In addition, the efficiency of the diesel generator is only 40%, so its efficiency is low, and the efficiency of direct use of electricity can reach more than 95%, and it basically does not consume electricity when the door crane is not working, and the energy efficiency ratio is very high. As a diesel generator, its own value is very high, and it consumes a lot of diesel, coupled with the low efficiency of diese...
