Abstract

The invention relates to an electrical control device for a crawler-type counter weight trolley, comprising a main machine control component arranged on a main machine of a crane and a counter weight trolley control component arranged on a counter weight trolley of the crane, wherein the main machine control component comprises a right main machine crawler travelling motor rotating speed sensor, a left main machine crawler travelling motor rotating speed sensor, a main machine controller and a main machine rotation angle displacement sensor; the counter weight trolley control component comprises a right counter weight trolley crawler travelling motor rotating speed sensor, a left counter weight trolley crawler travelling motor rotating speed sensor, a counter weight trolley controller anda counter weight trolley rotation angle displacement sensor; and the main machine controller and the counter weight trolley controller are connected to communicate by virtue of a CAN bus. By adoptingthe electrical control device provided by the invention, synchronous control on the main machine and the counter weight trolley is realized, and actions of the main machine and the counter weight trolley are combined to generate diversified operating modes, thus the automation strength is improved, the lifting capacity is improved, a counter weight is convenient to move, and the problem that desynchronization is caused by adverse impact of personal factors can be avoided.

Description

technical field [0001] The invention relates to electrical control of a counterweight trolley, in particular to an electrical control device and a control method for a crawler-type counterweight trolley. Background technique [0002] At present, there are two types of counterweight trolleys for foreign large-tonnage crawler cranes: tire type and crawler type. The tire-type counterweight trolley is relatively expensive, and the tires are prone to wear and tear due to the huge counterweight; the crawler-type counterweight trolley is designed to be driven by multiple drivers, and it is easily affected by human factors during the driving process. causing out-of-sync issues. [0003] A synchronous crane in the prior art is composed of a counterweight car, a chassis, a column, a cross arm, a lifting trolley, a cross arm track, and a ground track. The chassis and the counterweight truck can run synchronously on two parallel tracks, and the working range of the hook is within a re...
