Abstract
The invention provides a nine-step linkage ship unloading method. The ship unloading method comprises the following steps that: a trolley moves on the sea; a grab bucket falls down, the grab bucket moves while falling down during the moving of the trolley, when the grab bucket falls down to a position close to material to be grasped in a cabin, a handle for controlling the moving of the trolley uses the third gear or the fourth gear to shift the trolley to perform hook lifting and positioning operation in the cabin, the grasp bucket is lifted to a position above the material, and then the grasp bucket falls down to a position 1-2m above the material; the trolley is reset to zero; firstly the grasp is enable to fall down to the position of the material, the handle of the grasp bucket is controlled to be zero, and then the position of the trolley is leveled; the grasp bucket is closed; the grasp bucket is lifted; the trolley moves on the ground; the grasp bucket is opened; the trolley is reset to be zero. The nine-step linkage ship unloading method can quickly finish ship discharging task with high quality, reduce the working intensity, and improve the working efficiency.
Description
Technical field
The present invention relates to the method for unloading a ship, particularly a kind of nine steps interlocks are unloaded a ship method.
Background technology
During bridge-type grab ship unloader is applicable to, haven unloads a ship or the operation of unloading coal of power plant dock ship, and speed is fast, and efficiency is high.Bridge-type grab ship unloader can orbit, and under door frame, clear headroom can lead to transport vehicle, grabs bucket by after material picked up by ship, unloads to broach hopper, delivered to the band conveyor on harbour, then deliver to stockyard by hopper discharging opening.Unload a ship in process whole, grab bucket and capture material from cabin and be positioned at the operating speed of opening this process directly over hopper and operation quality to grab bucket and be directly connected to the effect that job task completes, it is the committed step of whole process of unloading a ship, but current method of unloading a ship speed is slower, can not meet increasing task of unloading a ship, work efficiency is low.
Summary of the invention
For solving the problems of the technologies described above, the invention provides one can fast, special quality completes the task of unloading a ship, and reduces working strength, the nine steps interlocks of increasing work efficiency are unloaded a ship method.
The technical solution adopted in the present invention is: a kind of nine steps interlocks are unloaded a ship method, described in the method for unloading a ship comprise the steps:
(1) dolly sea-run
Dolly runs from hopper to the cabin in direction, sea;
(2) grab bucket is fallen
In the process that dolly is advanced, grab bucket row limit, limit falls, instantly need in cabin capture material near time, the handle controlling trolley travelling uses third gear or fourth gear travelling car, carry out getting rid of hook Fixed Point Operation in cabin, by the position be thrown to above material of grabbing bucket, now grab bucket drops to the position of 1-2m above material;
(3) dolly back to zero
Control the handle back to zero of trolley travelling, dolly operation suspension;
(4) fall to putting in place handle back to zero
When now dolly has also arrived above material, directly grab bucket is dropped to material place, control the handle back to zero of grab bucket; When now dolly does not also arrive above material, first grab bucket is dropped to material place, control the handle back to zero of grab bucket, dolly is made uniform position or position of first being made uniform by dolly again, then grab bucket is dropped to material place, controls the handle back to zero of grab bucket;
(5) grab bucket is closed;
(6) grab bucket hoists;
(7) dolly land row
While grab bucket hoists, the hopper place that dolly starts landwards direction runs;
(8) grab bucket is opened
Dolly arrives directly over hopper, and grab bucket opened, material falls in hopper;
(9) dolly back to zero
Control the handle back to zero of trolley travelling, dolly operation suspension, completes and once unloads a ship.
Preferably, in described dolly sea-run process, before arriving in cabin under grab bucket, the material position that clearly will capture according to the material direction of commander's hand indication, and prejudge distance.
Preferably, described in when getting rid of hook Fixed Point Operation, the handle controlling trolley travelling pushes away third gear or fourth gear, after dolly has action, at once by handle back to zero.
Preferably, after described grab bucket is opened, grab bucket meeting is sinking one segment distance automatically, now, does not need to promote grab bucket, directly carries out the process of unloading a ship of next cycle.
The invention has the beneficial effects as follows: the present invention captures material by grabbing bucket in the process of unloading a ship from cabin and is positioned to grab bucket this process opened directly over hopper, find out the method for a set of " nine step interlocks ", whole operation process is made to become the process of an interlock, instead of independent action, action brevity and lucidity, it is accurate to grab goods, substantially increase work efficiency, by a hook 2 minutes before, add near a hook 1 minute, efficiency doubles; Adopt three gears or four gear travelling cars when hook fixed point is got rid of in cabin, push away handle, dolly moves with regard to back to zero, grab bucket is thrown to ideal position and chases after hook again and make uniform, and to compare with one grade or the two speed running trolleys kept off to ideal position, greatly reduces the time; A segment distance of rear automatic sinking is opened in grab bucket, can not have any impact completely on the operation of dolly, deducts the action promoting grab bucket, reduces unnecessary little trick, take care of the pence, and improves speed, reduces working strength; Under grab bucket in cabin before, pay attention to man-machine cooperation, clearly capture the position of material in advance, this step has following 3 advantages: 1. driver knows what's what, and operate dolly and move no longer equivocal, action is targeted; 2. frequently need not command behind the lower cabin of grab bucket, reduce the working strength of commander's hand; 3. shorten the time of underdeck operation, improve operating efficiency.
