Rubber-tyred container gantry crane automatic electricity getting system

Abstract

A rubber-tyred container gantry crane automatic electricity getting system comprises an electricity getting device and a slide wire track bracket that are controlled to act by a power system and a control system in a matching manner. The electricity getting device has an electricity getting trolley, a connecting mechanism and an electricity getting apparatus base. The slide wire track bracket hasan access / detachment section and an electricity getting section. The electricity getting trolley is composed of a main frame, a track locator, an elastic connector, an oscillating bearing, a travelling wheel and an electricity getting brush arranged on the trolley. The connecting mechanism comprises a first connecting bar, a second connecting bar, a third connecting bar, a floating connecting bar,a pull rod, a spring, a support bar, a pin, a transformation joint and a locating connecting bar. The electricity getting apparatus base comprises a base bracket, a main shaft, a horizontal rotary table, a locating pin and an electromagnet; the access / detachment section comprises a first track, a second track, a first detection plate, a second detection plate, a baffle and a supporting vertical post; and the connecting mechanism can lead the connection status of the electricity getting trolley and the electricity getting apparatus base to be switched between the access / detachment status and traction electricity getting status under the program control of the control system.

Description

technical field [0001] The invention relates to the technical field of gantry cranes, in particular to an automatic power-taking system for a tire-type container gantry crane. The tire type container gantry crane is referred to as "tyre crane" for short. Background technique [0002] In the prior art, there is application number 200610068525.4, application date 2006.08.19, publication number CN1915782A, name "Power Supply Device for Rubber-tyred Gantry Crane", which is provided with a sliding contact circuit on the fixed bracket, and the collector of the sliding contact circuit is fixed on a On the trolley where the trolley line moves in parallel, the lead-out line of the collector is connected to the electrical system of the rubber-tyred gantry crane, and the trolley is flexibly connected to the rubber-tyred gantry crane. The technology disclosed in the above-mentioned patent can realize the power supply function of the trolley installed on the sliding wire support, but th...

AI Technical Summary

Problems solved by technology

The technology disclosed in the above-mentioned patent can realize the power supply function of the trolley installed on the sliding wire support, but the trolley cannot be separated from the sliding wire support. After entering the new storage yard, there must be a manual connection between the tire crane and the trolley on the sliding wire support

Therefore, this technology cannot automatically connect and disconnect from the safety slide line and its track to take power, because the tire crane cart is easy to go off when it is walking; in order to make the rubber-tyred container Automatic power-taking on the slide line, that is, the power-taking device of the tire crane is installed on the tire crane through the connecting mechanism, and the tire is hung on different power supply line sections of the safety slide line. ) and the control system, so as to realize automatic access to and departure from the safety slide line and its track.
