Technical Field

The invention relates to the technical field of ship unloading mechanical devices, in particular to an intelligent environment-friendly continuous high-efficiency bridge type buried scraper ship unloader.

Background

The bulk cargo ship unloaders commonly used in ports are divided into an intermittent type ship unloader and a continuous type ship unloader, wherein the intermittent type ship unloader mainly comprises a bridge type grab bucket ship unloader, and is characterized by mature machine type, wide applicable ship type range and wide application. However, the grab bucket is adopted for unloading the ship, so three main problems exist: firstly, the self weight of the grab bucket is always in the production cycle as the ineffective load, so the energy consumption is high; secondly, the grab bucket is carried out in an open space in the process of grabbing materials from the cabin and transferring the materials to the hopper for unloading, so that the materials are easy to spill and dust is easy to fly, and the environment-friendly performance is poor; thirdly, the grab bucket must grab the material on the material pile, and in the stage of shallow material layer, the clearing work can be completed only by the cooperation of the clearing machine, so that the productivity in the stage is obviously reduced, and the intelligent operation is difficult to realize.

The continuous ship unloader mainly adopts two types of embedded scrapers and chain buckets, and has the advantages of good environmental protection performance and high production rate. But the requirement on materials is high, the number of mature machine types is small, and the current application is limited. The embedded scraper ship unloader is a continuous ship unloading device which lifts materials from a cabin to an arm support by means of a scraper and a chain moving in a closed groove body and transfers the materials to a wharf belt conveyor. Has the characteristics of light dead weight, good sealing performance and high efficiency. However, because of its high requirement for materials, it is only used for loading and unloading some materials with light volume weight, good drying property and good fluidity on the grain wharf.

The existing in-service embedded scraper ship unloaders are all in a cantilever crane type, and when the embedded scraper ship unloaders work, the whole operation surface of a cabin is covered by two motions of cantilever crane rotation and pitching. The problems caused are: firstly, these two kinds of movements are the circular arc motion, and speed is difficult too fast, consequently can increase the time of trading the storehouse or the conversion gets the material operation line to reduce the efficiency of unloading of whole ship. And secondly, the scraper blade material taking head must move linearly when unloading the ship, and the ship unloader can only realize two motions of synthetic rotation and pitching, so that the difficulty of intelligent operation of the whole machine is increased. Thirdly, when a plurality of devices are used for loading and unloading the ship together, the wharf shore line occupied by each device is long, and the arrangement of the wharf shore line is possibly difficult.

The front beam and the rear beam are connected through a floating hinge shaft, the floating hinge shaft is positioned above the front beam and the rear beam, and a vertical shear-resistant platform is matched between the front beam and the rear beam. When the vertical scraper device is subjected to the upward jacking force of the ship bottom under the action of surge, the front beam can automatically rotate upwards around the floating hinge shaft and is separated from the vertical shear-resistant platform, so that the damage to the ship bottom is avoided; the folding pull rod is composed of three sections, and two adjacent sections are hinged through two central hinges respectively.

A track for the trolley to travel is simultaneously arranged on the front beam and the rear beam, and the arm support belt is arranged on one side of the track in parallel; the upper surface of the back beam is also provided with a winch which is sequentially connected with pulley blocks respectively arranged on the upper surface of the back beam and the top of the guide cylinder through ropes.

2. The arm support mechanism is provided with a balance weight to balance the weight of the front beam, the trolley and the vertical scraper system. When the ship unloader works, the synthetic gravity center of the parts is always ensured to be within the outer diameter of the guide post, so that the overturning moment can be reduced, and the arm support mechanism can easily slide along the guide post; the arm support mechanism rotates around the guide cylinder to facilitate the ship to leave and approach to the shore, and the vertical scraper device can be landed for maintenance and repair and can be fixed under special working conditions such as typhoon.
