Description

New linear reciprocating high-efficiency intelligent environmental protection continuous chain bucket ship unloader

technical field

The utility model relates to the technical field of ship unloading machinery, in particular to a novel linear reciprocating, high-efficiency, intelligent and environment-friendly continuous chain bucket ship unloader.

Background technique

For bulk cargo with large bulk density or uneven particles, such as coal and ore, the current dock unloading equipment has two types: intermittent and continuous. Intermittent ship unloaders are mainly bridge-type grab ship unloaders, which are characterized by mature models and wide applications. However, due to the use of grab buckets to unload ships, it has not been able to solve the problems of high energy consumption, poor environmental protection performance (material spillage, dust flying), low average efficiency and difficult to realize intelligent operation.

The existing continuous ship unloader is mainly L-type chain bucket ship unloader, which has good environmental protection performance and high productivity, but its application is very limited. The main reason is the defect of its working method: the L-type chain bucket ship unloader is Boom type, when working, use three circular motions of boom rotation, luffing, and chain bucket reclaiming head rotation to cover the working surface of the cabin with the movement of the cart. If the speed of the circular motion is too fast, the inertial load will increase significantly, so the speed cannot be too high, which will make the ship unloader take a long time to change the reclaiming operation line, and reduce the unloading efficiency of the whole ship. The compounding of circular motion also makes it difficult to realize the automatic operation of the whole ship. In the face of large ships, the wharf shoreline occupied by multiple equipment unloading together is long and difficult to arrange. In addition, the operation mode of the L-type chain bucket system reclaiming head is rotary reclaiming, and the retrieving direction is just perpendicular to the traction direction of the chain, and is also just perpendicular to the direction of the bucket mouth of the chain bucket, which causes the material to the side baffle of the bucket. The pushing resistance is relatively large. This lateral force acts on the cylindrical arm of the chain bucket system, causing it to twist and bend, and is transmitted to the structure of the whole machine and the slewing mechanism, making the related parts easy to damage and accelerating the wear of the chain. Especially for ore unloading, the resistance is very large, so the L-type chain bucket ship unloader is rarely used in ore terminals. At the same time, for viscous materials, the materials may not be unloaded cleanly and return materials may occur. Moreover, due to the use of side feeding, it is also impossible to realize the clearance of the bilge, which reduces the average production efficiency of the whole ship's loading and unloading.
