Abstract

The invention discloses bulk cargo receiving and unloading equipment and a balance arm frame system thereof. According to the technical scheme, the bulk cargo receiving and unloading equipment is mainly characterized by comprising a main bracket and furthermore comprises a main arm, a connection arm, an auxiliary arm and a swing arm drive portion, one end of the main arm is a main connection end hinged to the main bracket, and the other end of the main arm is a work end; the auxiliary arm is provided with an auxiliary connection end close to the work end, a hinge end hinged to the main bracket and a load bearing end away from the work end in sequence in the length direction, the load bearing end is provided with a heavy object, one end of the connection arm is hinged to the auxiliary connection end, and the other end of the connection arm is hinged to the main arm; and the swing arm drive portion is used for driving the main arm to move and making the work end achieve vertically lifting movement. An internal parallelogram structure is utilized by the balance arm frame system, and steadiness in the movement process is greatly improved; the internal power of a main supporting rod with an automatic oil smearing function is from action of the internal parallelogram structure of the balance arm frame system, automatic outer-side oil smearing is performed on a cylindrical shaft, and operation steadiness of the bulk cargo receiving and unloading equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bulk cargo handling equipment, in particular to a bulk cargo loading and unloading equipment and a balance boom system thereof. Background technique [0002] At present, the structure of the bulk cargo handling ship unloader, such as the Chinese invention patent CN206081950A, a fixed grab ship unloader whose main structure includes a turntable, a rotary mechanism, and a frame structure positioned on the turntable, the turntable drives the turntable to carry out a cycle. Rotating in the opposite direction, the turntable is also hinged with a jib, which is used to drive the jib to swing up and down around the hinge point, so as to drive the hopper at the end of the jib away from the turntable to change its position. [0003] Although the overall position conversion flexibility of the above-mentioned ship unloader is high, since the boom is only driven by one end of the driving source, and the connection poi...
