Embodiment 1

[0035] ZQX1500 grab bridge ship unloader: including metal structure, four-drum mechanism, trolley running mechanism (including trolley), luffing mechanism, cart running mechanism (including cart) and grab running mechanism (including grab) . The bridge crane is a four-drum traction trolley type grab bridge ship unloader. The structure and layout of the whole machine are as follows: figure 1 (a) and figure 1(b) shown. When working, after the grab grabs the coal from the unloading ship warehouse, the grab and trolley run to the land side, and the coal is unloaded into the drop hopper inside the front mast, and falls onto the belt of the pier corridor through the machine's internal feeding system. The metal structure of the bridge crane adopts the box girder type, and the front and rear girders are connected by pin shaft hinges. In the non-working state and when the sea-going ship is docking or leaving the shore, the front girder is raised to allow the sea-going ship to pass fr...

Abstract

The invention relates to an efficient material unloading method based on a ZQX1500 grab bridge type ship unloader. According to the efficient material unloading method, according to effective technological parameters of the ZQX1500 grab bucket bridge type ship unloader, inertia and delay generated in the operation process of all mechanisms (including a four-drum mechanism, a trolley traveling mechanism, a cart traveling mechanism and a grab travelling mechanism ) are utilized, namely, in the whole operation process, a grab opening and closing steel wire rope is always in the operating state, when a grab reaches a normal lifting height, a user should operate a handle to enable the grab to be immediately opened, and a trolley already travels to the position above a funnel at the moment, andthen materials are efficiently unloaded. Compared with the prior art, the efficient material unloading method overcomes the problem that by the adoption an existing mode, a rated coal unloading quantity is difficult to reach; it is ensured that the actual coal unloading quantity exceeds the rated coal unloading quantity by 20%, namely the coal unloading workload of 1800 t / h can be achieved; and inthis way, the work efficiency of the bridge type ship unloader is greatly improved, electricity, equipment loss and demurrage charge of a bulk cargo ship are saved, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of ship unloaders, in particular to an efficient material unloading method based on a ZQX1500 grab bridge ship unloader. Background technique [0002] The ship unloader is a special machine for unloading ships at the wharf. It can unload the bulk materials in the cabin to the conveyor belt conveyor, and then send the materials to the storage yard through the belt conveyor. The ship unloader mainly has the following three basic functions: (1) Grabbing materials from the cabin; (2) Lifting materials from the cabin to the grab of the ship unloader; (3) Transporting materials to the hopper on the wharf , and unload it on the conveyor belt conveyor. [0003] The normal operation modes of the ZQX1500 grab bridge ship unloader are as follows: 1. Full manual operation mode; 2. Semi-automatic operation mode; 3. Fully automatic operation mode. Currently, the most commonly used mode of operation is semi-automatic ope...
