Assisting arm telescopic lifting mechanical arm

The invention discloses an assisting arm telescopic lifting mechanical arm which comprises a stand column, a cross beam and a chain. The bottom of the stand column is rotationally installed on a rotary base and is driven by a rotary motor, pulleys are installed at the two ends of the cross beam respectively, one pulley is driven by a lifting motor, one end of the cross beam is perpendicularly and fixedly connected with the upper end of the stand column, a telescopic sleeve is fixedly connected below the other end of the cross beam, a telescopic rod is arranged in the telescopic sleeve, a chuck is fixedly connected with the lower end of the telescopic rod, the chain spans the pulleys at the two ends of the cross beam, one end of the chain is downwards connected with the top of the telescopic rod, and a balancing weight is hung below the other end of the chain. The assisting arm telescopic lifting mechanical arm has the advantages that after bricks are clamped and lifted, the bricks are transformed to another position through one-arm rotation, and layered stacking between two points is achieved; the balancing weight is hung at one end of the chain, the other end of the chain is connected with the chuck, and thus the balance of the whole device can be effectively maintained; automatic operation is achieved, efficiency is high, a large amount of manual cost is saved, and the safety of operators is ensured.
