Slide moving feeding method of positioning operation of rail-free port gate type crane

Abstract

The method of moving sliding joint power supply during directional operation of trackless port gantry cranes involves the method of providing power grid power supply by sliding joint movement when the trackless port gantry cranes with self-provided power supply are operating. According to the technical scheme of the present invention, the upper part Install the power transmission wire guide, there is a power transmission guide rail in the power transmission wire guide, and the guide rail is installed on the lower part of the bracket. The brush on the upper end is inserted into the notch of the power transmission guide rail, and is in contact with the power transmission guide rail. The traction mechanism is connected to the collector trolley, and there is a collector cable on the collector. There is a walking mechanism at the lower end of the trackless door crane. The electric trolleys are connected to each other by traction mechanism. The invention enables the trackless port gantry crane to be equipped with no or less diesel power generating sets, and the main power consumption is to use the grid power supply, so as to achieve the goals of reducing energy consumption costs and emission pollution of internal combustion engines.

Description

technical field [0001] The invention relates to a method for feeding railless port cranes in a directional operation area by means of a mobile sliding connection to provide the power supply of the urban power grid. Background technique [0002] Port gantry cranes can be divided into two types: tracked and trackless. The trackless port gantry crane (referred to as trackless gantry crane) has the flexibility of transition (that is, from one operation site to another), and is not restricted by the fixed-point operation area in the port, which improves the utilization rate of port equipment and reduces the number of port trackless gantry cranes. The number of configurations and other characteristics are very popular with ports. According to statistics, more than 90% of the port container door cranes all over the world use trackless container door cranes. [0003] The trackless door crane belongs to a kind of electric drive equipment, and its cart movement, trolley movement, ca...

Problems solved by technology

Due to its non-directional movement and variable moving paths, it is impossible to use the grid power supply through cable connection, and rely on the power provided by the diesel generator set equipped with the trackless door crane itself to work.

The power supply of diesel generator sets is transformed into electrical energy through chemical energy and mechanical energy conversion. The energy conversion efficiency is low, and the price of diesel is high. The power supply mode of the trackless door crane consumes a lot of energy and the cost of electricity is high.

The unit electricity cost of diesel generator sets is three times higher than that of grid power supply, and diesel engine gas emissions, noise, and waste oil and water leakage all cause greater pollution to ports
