Description

A kind of ship unloaders protective device and ship unloaders

Technical field

The present invention relates to ship unloaders field of mechanical technique, more particularly to a kind of ship unloaders protective device and it is provided with the unloading The ship unloaders of machine protective device.

Background technology

At present, the ship unloading equipment of large amount bulk cargo (such as coal, iron ore) is mainly ship unloaders, and ship unloaders are usually all set There are material fetching mechanism and the hoisting mechanism being connected with material fetching mechanism, material fetching mechanism generally includes to inhale coal head and be arranged to inhale coal head periphery Material can be captured from ship by grab bucket around some grab buckets for inhaling the rotation of coal head, material fetching mechanism, hoisting mechanism is grabbed for drive Bucket movement upwards.

But the protective device at current suction coal head is only a barred body for protruding from grab bucket, when the rib cage of cabin is convex When going out, the grab bucket for inhaling coal head periphery is easily scraped off, and in turn results in a series of equipment accidental damage, or even cause to stop production.

For example, the grab bucket being scraped off still is ascended into the enhancing tube of hoisting mechanism, and it is stuck with the inner wall of enhancing tube, it will carry The chain of the system of liter is strong to be broken.Although inductive switch is mounted near enhancing tube at present, when scratch of grabbing bucket deforms, Touch sensing of grabbing bucket switch, to stop the work of ship unloaders, still, the installation site of current inductive switch is simultaneously unreasonable, i.e., Switch grab bucket touch sensing, due to effect of inertia, chain is still operating and then driving grab bucket to enter in enhancing tube, causes equipment The equipment breakdown such as damage and the bad other parts of strong drawing.

Exemplified by work efficiency according to ship unloaders is 1500T/h, the workload in one day is 1500t/Hx24h= 36000t, the economic benefit of one day is 36000tx18.5 members/ten thousand yuan of t=66.6;General ship all unsnatches goods in 2 days to harbour Thing, an expensive cost of delays will be also paid beyond the time limit and is used.And due to being set caused by above-mentioned ship unloaders protective device imperfection Standby damage, is repaired minimum 5 to 6 days, has delayed the progress of unloading, bunder, stock yard is stopped work, has been seriously affected harbour Run well, the income of user, and bring the loss such as maintenance cost and damages to user.

The content of the invention
