Embodiment Construction

[0022] The specific implementation of the present invention combines the circuit of the controller, taking the actual work of the rubber-tyred gantry crane as an example. The technical gist of the system and method is that there is a four-bar linkage set between the collector and the rubber-tyred gantry crane, and the controller controls and drives the hydraulic system of the four-bar linkage set through the control system program and received signals. The connecting rod group drives the collector to stretch out, and the rubber-tyred gantry crane drives the collector to automatically guide the upper rail 2, the lower rail 6, and the safety sliding contact line 1 from the side of the track in sequence.

[0023] When the rubber-tyred gantry crane is turning on the road, the collector shrinks to zero position (to avoid shaking caused by the movement of the rubber-tyred gantry crane), and prepares to enter the operation box area at a speed of 1m / s. The photoelectric switch of the r...

Abstract

The invention relates to an intelligent current collector system of a tyre type gantry crane for hoisting cargoes and containers in a dock and a control method thereof. The system is designed aiming at the unreasonable design of the prior similar products. The key points in designing comprise: a track is provided with a safety sliding contact line, an upper track, an upper address identification plate, a lower address identification plate, and a lower track; the current collector is provided with a photoelectric sensor, an electromagnet, a guiding wheel set and a traveling wheel set; and the current collector is connected with a support base of the tyre type gantry crane through a four-link-rod set. The control method comprises: a controller drives a horizontal oil cylinder and a lifting oil cylinder to adjust space position of the current collector, and the current collector is sequentially guided to the upper track, the lower track and the safety sliding contact line from the side upper part of the track. The intelligent current collector system has the advantages of improving the conveying efficiency and speed of the power supply type tyre type gantry crane, effectively lowering operating cost, and minimizing the number of equipment; and the control method can improve the safety of automatic guide and the accuracy of positioning. The invention is suitable for updating match of electric equipment of the tyre type gantry crane for hoisting the cargoes and the containers in the dock.

Description

technical field [0001] The invention relates to electrical equipment for hoisting wharf goods and containers, and relates to an intelligent collector system and control method for a rubber-tyred gantry crane. Background technique [0002] At present, the "oil-to-electricity" technology of rubber-tyred gantry cranes (hereinafter referred to as RTG) is being promoted, and the "mains" on-board methods include cable drum type, elevated trolley line type and low-frame trolley line type. The way of installing the cable reel is to set the cable reel on one side of the gantry, and the cable is wound on the cable reel. One end of the cable is connected to the power supply circuit of the RTG, and the other end is connected to the corresponding The "mains box". When the RTG is running, the cable drum retracts and unwinds the cables according to the distance between the RTG and the mains junction box. The way of overhead trolley line is to set up high-altitude copper trolley line in t...
