Exertion and maintenance of the hoist--three
4.1 The sense organ is checked
Hoisting machinery safe practice inspection according to examine
personnel through watch, hear, scent, ask, touch, go on majority
very. "hoisting
machinery inspection procedure "( 2002)It is that sense organ
is examined that hoist tool instruments stipulated examine and
account for more
than 70% of total project in the project on the 296th. Through
seeing, hearing, taking a sniff at, asking, fumbling and carrying
on overall ocular
diagnosis to the hoist tool instrument of sense organ, to obtain
necessary information and data.
See: According to the structural characteristic of the hoisting
machinery through the vision, observe its important transmission
position, bear the
structural main point of strength, phenomenon source of the trouble
to promise.
Hear: Analyse through sense of hearing hoist tool instrument
apparatus every position operation sound normal, judge the unusual
sound comes
from the position, find out about the cause of disease, finds out
the cause of disease.
Scent: Distinguish the on-the-spot smell of mechanical movement
position of jack-up through the sense of smell, distinguish
overheated, wearing
and tearing, overbunt position of the spare part.
Q: Inquire driver and relevant personnel in the operation course of
the hoist, apt to appear in the trouble point, break down and
pass,
classification. Judge the safe practice state of the hoist.
Fumble: Operate the part, changing according to temperature,
vibration situation through touching the hoist with hands, judge
the position of
trouble and trouble property.
The inspections of 4.2 testers
According to the tool instrument development trend of the domestic
and international hoist, the modernized application state monitors
and
diagnoses with the trouble technology has already been popularized
extensively in the hoist tool instrument is designed and used.
Under the tool
instrument operation state of the hoist, utilize and monitor and
diagnose the instrument and expert's monitoring system, examine the
hoist tool
instrument ' Supervise) Examine, master the technological
state of the hoist at any time, foresee trouble sign and reason of
complete machine or
system, dispel the accident in the bud.
Safety inspection of the common part of 4.3 hoists
( 1) Cliver.
Whether check the mark of the cliver and defend taking off the
device to fulfil requirements, whether the cliver has defects such
as crackle,
shelling splitting,etc.; The increase, turning back of degree is
out of shape that the section of the cliver wears and tears, opens
one's mouth,
whether exceed standard; Cliver shank and tired deformation of
existence of surface, crackle, relevant pivots, a set of wearing
and tearing
situation.
( 2) Steel wire rope.
Check it accords with the designing requirement whether
specification of the steel wire rope, the type and pulley reel are
matched. Whether
fixture of steel wire rope such as the pressing plate, rope card,
contract lump in the fixed end of the steel wire rope fulfil
requirements. Wearing
and tearing, disconnected silk, twists together, flattens, bends,
broken burst, corroding etc. and exceeding standard of the steel
wire rope.
( 3) Apply the brake to fit.
The establishment of the brake, whether the pattern of the brake
accords with designing requirement, defects such as the pull rod,
tired
deformation of existence of spring, crackle of the brake,etc.;
Pivot, mandrel, make driving wheel, apply the brake the friction
disc wears and tears
and exceeds standard, oil spill that the hydraulic pressure applies
the brake; Whether could fulfil requirements to adjust, make the
strength of
kinetic energy while applying the brake in the interval.
( 4) Reel.
Whether a barrel, tube reason have situations such as crackle of
fatigue, damage,etc.; Rope trough and tube wall wear and tear and
exceed
standard; The rim of reel highly twines floor with the steel wire
rope and could be matched to count; Whether lead the rope device,
arrange the
working condition of the rope device to fulfil requirements;
( 5) Pulley.
Whether the pulley defends taking off the trough device of the
rope; Whether pulley rope trough, rim have states such as crackle,
broken side,
wearing and tearing and exceeding standard,etc., it is flexible
that the pulley rotates.
( 6) Moderating machine.
Whether the moderating machine has unusual sounds such as sound of
violent friction between metal wares, vibration, shell
radiation,etc. when
being operated; Is the end of the axle sealed intactly, the set
bolt has state such as being flawed or damaged to become flexible;
Moderate
machine lubricating oil choose, level, vertical to moderate plane
lubricate oil pump run the oil, the turning on type transmission of
gear wheel
lubricates etc. and fulfils requirements.
( 7) Wheel.
To step on surface, shaft have tired crackle phenomenon, wheel step
on surface shaft wear and tear and exceed standard wheel. Whether
gnaw
the phenomenon of the rail while operating. Lead to the fact what
the reason for gnawing the rail is.
( 8) Shaft coupling.
Whether the part of the shaft coupling is flawed or damaged, join
and become flexible, operate and assault the phenomenon. Shaft
coupling,
pivot, pivot hole, buffering rubbers to enclose and wear and tear
and exceed standard. Whether two parts of what the shaft coupling
is connected
with quilt are concentric.
