Abstract

A locking device for locking an outrigger in engineering machinery comprises a housing (1) having a limited chamber inside and having a left end provided with an opening (10); a latch (2) disposed in the chamber, capable of moving between a first position and a second position in a left / right direction, and provided with a protruding shoulder(21) arranged at a predetermined distance away from a left end thereof, wherein when in the first position, the left end of the latch extends out of the chamber from the opening and the protruding shoulder abuts against a left side wall of the chamber, and when in the second position, the left end of the latch retracts into the chamber; an elastic member (3) sleeving the latch and pressing the protruding shoulder in a leftward direction in a biased manner; and a driving assembly (5), the driving assembly being used for driving the latch to move from the first position to the second position. The locking device is capable of reducing labor intensity and is reliable in locking.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an engineering machinery for locking outriggers and a locking device thereof. Background technique [0002] In construction machinery such as pump trucks and cranes, when the boom is unfolded or heavy objects are lifted, the outriggers will be stretched out in order to meet the stability requirements, and the outriggers will be retracted to reduce the volume when the work is completed. To meet the needs of walking, in order to prevent the outriggers from swinging due to accidents when walking, the design specifications of construction machinery such as pump trucks stipulate that mechanical locking devices must be provided after the outriggers are retracted to ensure that the outriggers are in the car body during travel. Do not open. For this reason, all pump trucks are equipped with mechanical locking devices at present. [0003] At present, all such locking devices are man...
