Automatic electricity conversion apparatus for rubber-tyred crane transmission

Abstract

The invention relates to an automatic electricity conversion apparatus for the rubber-tyred crane transmission. The apparatus which comprises an electricity getting dolly which is fixed on a sliding contact wire and can move on the sliding contact wire is characterized in that: the electricity getting dolly has a socket; a rubber-tyred crane has a movable plug; the plug is inserted into the socket to make the rubber-tyred crane get electricity from the sliding contact wire; and the rubber-tyred crane has a plugging mechanism for inserting the plug into the socket or pulling the plug out of the socket. The electricity getting dolly is directly arranged on the sliding contact wire in the invention, so the reduced mass of conveying rods allows the service life and performances of the conveying rods to be guaranteed, the protection level of the sliding contact wire to be improved and connecting performances between the electricity getting dolly and the sliding contact wire to be improved.

Description

technical field [0001] The invention relates to a power supply and power exchange device for container hoisting equipment, in particular to an automatic power exchange device for port container tire crane transitions. Background technique [0002] With the increasingly close economic and trade contacts and exchanges, the port transportation industry has also flourished. There are mainly two types of hoisting machinery used for loading and unloading at the port container terminal yard, one is rail-mounted gantry cranes, and the other is tires. Hanging gantry crane. [0003] The operating power of the rail-type gantry crane on the wharf is powered by the power grid, and the connection of its electrical system is directly fixed on the current collector on the frame of the crane body to contact the trolley line, and the power grid connects with the cable reel through the cable reel. The trolley line is connected, and the collector is connected with the electrical system of the ...

Problems solved by technology

Some of the existing automatic tire crane automatic transition devices use electric, pneumatic or hydraulic transmission to install the power-taking trolley on the tire crane, and use the above transmission method to take power through the trolley line. Although this type of method can realize fully automatic transfer, due to the high installation accuracy requirements of the trolley line and the same power-taking trolley, it is difficult to avoid the power-taking trolley detaching from the trolley line and returning to the field during the transition process in windy and rainy weather. The impact caused by wind and rain entering during the tire crane process, for example, it will cause poor contact between the trolley and the trolley, and the trolley and the trolley will wear out due to the need to plug in and out when entering the field. , thus reducing the protection level that the trolley line should have
