Portable hydraulic movable arm of small crane

Abstract

The invention discloses a portable hydraulic movable arm of a small crane, which comprises a hydraulic movable arm main body; a dismounting and mounting part is mounted on the bottom surface of the hydraulic movable arm main body; the dismounting and mounting part is of a long box-shaped structure with an open upper surface open and a hollow interior; two rotating rods with opposite rotating directions are rotationally mounted in the dismounting and mounting part; driving gears are fixedly mounted on the outer walls of the two rotating rods; a plurality of mounting grooves flush with the driving gears in position are formed in the bottom end face of the dismounting and mounting part; overturning plates are hinged to the interiors of the mounting grooves; the overturning plate is matched with the mounting groove and is overturned and embedded towards the interior of the mounting groove; an adjusting box is installed on the side, away from the telescopic end of the hydraulic movable arm main body, of the dismounting and mounting part; the adjusting box communicates with the dismounting and mounting part and is provided with two rotating holes allowing the two rotating rods to penetrate through; and mounting plates meshed with the two rotating rods are respectively arranged in the adjusting box. According to the portable hydraulic movable arm of the small crane, through the ingenious structural design, the moving convenience of the hydraulic movable arm can be effectively improved; and the portable hydraulic movable arm can be widely popularized.

Description

technical field [0001] The invention belongs to the technical field of crane hydraulic boom, in particular to a portable hydraulic boom of a small crane. Background technique [0002] Crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places. The name of the crane is the unified title of lifting machinery. Usually called cranes are mainly car cranes, crawler cranes and tire cranes. The usefulness of the crane lies in hoisting equipment, emergency rescue, lifting, machinery, and rescue. [0003] A crane is a common name for a crane. A crane is a kind of hoisting machinery, which is a kind of machinery that performs cyclical and intermittent movements. A working cycle includes: the pick-up device lifts the item from the pick-up place, then moves horizontally to the designated place to lower the item, and then performs a reverse movement to return the pick-up device to its original position for the ...

AI Technical Summary

Problems solved by technology

A working cycle includes: the pick-up device lifts the item from the pick-up place, then moves horizontally to the designated place to lower the item, and then performs a reverse movement to return the pick-up device to its original position for the next cycle. The hydraulic boom is a crane However, the hydraulic boom is often heavy when it is checked, and there are no related moving tools, which makes it inconvenient to transfer and carry, and cannot meet the needs of use.
