Chain bucket reclaiming equipment and corresponding ship unloader

Abstract

The invention discloses chain bucket obtaining equipment which comprises a door frame type equipment support structure configured to be a bearing device of the chain bucket obtaining equipment, a main beam, a trolley and an obtaining device. The main beam is arranged on the equipment support structure, the trolley is arranged on the main beam through a trolley frame, the trolley frame can reciprocate along a track arranged on the main beam, the obtaining device penetrates through the main beam and is perpendicular to the main beam, and the obtaining device is connected with the trolley frame. When the obtaining position of the obtaining device needs to be changed, the obtaining device is pulled through movement of the trolley, and the obtaining device is moved to the needed position. The invention further discloses a ship unloader. The chain bucket obtaining equipment is large in grabbing amount, low in dead load, high in structural strength, capable of adapting to seagoing vessel continuous ship unloading operation, high in ship unloading efficiency and small in environmental pollution.

Description

Technical field [0001] The invention relates to a reclaiming equipment, in particular to a chain bucket reclaiming equipment and a corresponding ship unloader. Background technique [0002] With the development of the national economy, various ports and terminals have higher and higher requirements for the environmental performance of loading and unloading equipment, and the country is paying more attention to the requirements for energy saving and emission reduction. [0003] In the prior art, bridge-type grab ship unloaders are used for loading and unloading, which are suitable for a wide range of ship types and simple maintenance, but are not environmentally friendly, high cost, high energy consumption, and large terminal construction costs; portal grab ship unloaders have low cost, but Low efficiency and poor environmental protection, basically completely eliminated; L-type chain bucket ship unloader is characterized by good environmental protection and high efficiency. The dis...

Problems solved by technology

For large bulk carriers, due to the large turning radius of unloading in this way, adjacent cabin operations cannot be realized, and the utilization rate of the terminal is low.

The chain tensioning method of the L-type chain bucket ship unloader is to realize the chain tensioning through the oil cylinder, but because the oil cylinder tensioning device is located in the cabin, dust can easily enter the hydraulic pipeline, causing hydraulic system failure. Practice has proved that hydraulic tensioning The failure rate of the method is high, which seriously affects the unloading efficiency of the terminal

[0008] The chain bucket lifting method of the existing L-shaped chain bucket ship unloader is to realize the amplitude improvement of the L-shaped material taking head through the oil cylinder, and realize the overall lifting of the entire front arm and the L-shaped material taking head through the luffing oil cylinder, but Due to the lagging response of the oil cylinder action, the L-shaped chain bucket reclaimer and the front outrigger can be regarded as rigid structures. Once encountering the jacking force caused by the surge, they cannot be effectively unloaded, thus causing damage to the structure.
