Dredger clamping safety device

Abstract

The present invention provides a digging machine clamp holder safety device which is used to used to prevent the separation of the clamshell excavator from the excavator and make the separation operation of the safety device become easier when do the replacing operation to the clamshell excavator, etc. and prevent the safety accident that is likely to happen because of the malfunction of the hydraulic equipment or cylinder. The digging machine clamp holder is provided with the following components: the connectors which are arranged on the front end of the excavator arm and the cylinder of the clamshell excavator; a fixed hook and a rotating hook which are arranged at the lower part of the connector and are combined with the fixed pins at the two sides of the clamshell excavator; and a cylinder which is installed on the connector and the rotating hook and makes the rotating hook rotate by the expansion of the cylinder rod thereby fixing the fixed pin of the excavator clamshell excavator, the digging machine clamp holder safety device includes the following components: a first supporting part which is arranged at the front surface of the cylinder; a second supporting part which is oppositely arranged to the first supporting part at the side of the cylinder rod and the rotating hook; and a supporting unit which guides the locking/releasing of the rotating hook by the advancing and receding of the third supporting part between the first supporting part and the second part by the cylinder rod.

Description

technical field [0001] The present invention relates to an excavator gripper safety device which prevents the bucket from spontaneously separating during use by securing the bucket to the gripper using a cylinder mounted on the gripper , so as to prevent safety accidents, etc. Background technique [0002] Usually, the excavating mechanism is a cantilever, an arm, a bucket, etc. that can be articulated and can be moved by cylinders, and the excavating mechanism is such that hydraulic pressure is supplied from a hydraulic device (not shown in the figure) to each cylinder through a hydraulic line. The bucket is hinged to the arm and the bucket cylinder through the excavator clamp, whereby the bucket can be articulated at the end of the arm. [0003] As shown in Fig. 1 and Fig. 2, the clamper of conventional excavator is made up of following each parts: be installed on the connecting body 100 on the excavator arm and the bucket cylinder; Be installed on the side of above-menti...
