Abstract

An embodiment of the present invention relates to a quick-clamp control apparatus of a construction machine that includes a clamp for mounting an attachment of a construction machine, and is characterised by comprising: a selection input unit for generating a selection signal during an ''on'' operation by a driver; an operation input unit for generating an operation signal during driver operation;a clamp driving and fastening unit for loosening and fastening the clamp; and a control unit for controlling the clamp unit so that the driving of the clamp is loosened when the operation signal is input after the selection signal has been input.

Description

technical field [0001] An embodiment of the present invention relates to a quick clamping control device and control method for engineering equipment. Background technique [0002] Generally, heavy equipment used at a construction site or a civil engineering site, such as an excavator, is configured so that various attachments can be exchanged according to the purpose to perform various operations. For example, in addition to excavation using a bucket In addition to work, it also performs concrete building crushing and steel bar cutting work using a crusher, rock and concrete breaking work using a breaker, scrap metal and rock transporting work using a grab, and clamshell Clamshell bucket shafts and waterway building foundation construction operations, etc. [0003] Usually, the attachment is coupled to the arm or the boom of the excavator in a detachable structure so that it can be replaced according to the use of the work. [0004] In conventional heavy equipment, in ord...
