Problems solved by technology

In the process of manual operation, if the operation is improper or wrong, such as the opening and closing rope of the grab bucket is too loose, it is easy to cause material leakage from the grab bucket; Accidents caused by damage to the power source of the opening and closing drum or breakage of the opening and closing rope
Manual operation not only requires rich experience and operating skills, but also requires the operator to concentrate when moving, opening and closing the grab bucket, and the labor intensity is high.
[0004] In addition, the working environment of the grab ship unloader is complicated, which is easy to cause bumps, and even bump into cargo ships or people on the wharf, causing accidents

Embodiment Construction

[0020] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0021] Please refer to figure 1 , is a structural schematic diagram of a grab ship unloader disclosed in this embodiment, including: a grab driving mechanism D1, a grab D3 and a trolley D2 carrying the grab D3, and the trolley D2 is used to drive the grab D3 to move, wherein , the grab D3 is sequentially connected to the trolley D2 and the lifting reel in the grab drive mechanism D1 through the lifting rope D4; Close the reel. In a specific embodiment, the lifting drum in the grab drive mechanism D1 realizes the movement of the trolley by winding / releasing the lifting rope D4, thereby driving the grab bucket D3 to move; the opening and closing drum in the grab bucket drive mechanism D1 passes Coil / release the opening and closing rope D5 to realize the opening and closing of the grab bucket D3.

Abstract

The invention discloses a grab ship unloader as well as a driving method and device of the grab ship unloader. The driving method for a grab driving mechanism comprises the steps of acquiring an unloading position and an initial position of a grab; planning a moving track from the initial position of the grab to the unloading position; acquiring the pendulum length of the grab; calculating the grab starting accelerated speed according to the pendulum length of the grab and the preset moving speed of the grab; outputting a grab starting accelerated speed instruction to the grab driving mechanism according to the calculated accelerated speed; and outputting a moving instruction to the grab driving mechanism according to the planed moving track. The effect of automatically moving the grab is achieved, so that the labor intensity of operating staff is relieved, and the swing of the grab is reduced. The invention also discloses a grab ship unloader.

Description

technical field [0001] The invention relates to the field of ship unloaders, in particular to a grab ship unloader and its driving method and device. Background technique [0002] Grab ship unloader is a kind of special ship unloading equipment applied on large bulk material wharf. It is widely used because of its strong adaptability to materials and ship types, low failure rate, and small cleaning volume. For example, use the grab bucket of the grab ship unloader to grab the bulk cargo (such as coal material) transported by the bulk ship, and then the grab bucket is driven by the reel to move to the discharge position on the land side (such as coal scuttle ), and open the grab bucket to release the cargo grabbed by the grab bucket to the discharge position on the land side, and transport the cargo to the destination via a belt conveyor or vehicle. [0003] In the prior art, experienced operators are often required to adjust the lifting, translation and moving speed of the...
