Abstract
The title of the utility model is: the gantry of petroleum steel pipe is carried on pipe laying barge.A kind of technical field: hoisting machinery.The drip irrigation device of the crane is: crane includes traveling mechanism of the larger traveller, overturn-preventing safety door hook, lifting mechanism, suspender.Cart operation relies on gear, rack drives, linear motion, and cart wheel will not skid and gnaw rail；The safety door hook for the trade shape for preventing crane from toppling is installed on cart；There are 4 groups of lifting mechanisms, is used according to the different weight of petroleum steel pipe and different length permutation and combination；Petroleum steel pipe special hanger is used, the suspender whole process automatic operation.It along with suspender horizontal movement track is straight line, can quickly position, so that the working efficiency of crane greatly improves.Solves the technical issues of existing crane for hoisting steel pipe inefficiency.The main application of the machine is mounted on pipe laying barge main deck, is used for the handling of petroleum steel pipe, stacking on pipe laying assembly line.
Description
Technical field
The utility model relates to a kind of hoisting machineries, are mounted on pipe laying ships main deck, for petroleum steel on pipe laying assembly line
The handling of pipe, stacking.
Background technique
The handling of petroleum steel pipe, way of stacking are on pipe laying barge at present: set up at the ship side of main deck side it is fixed, can
The crin of revolution is hung, and the motion profile for being hung petroleum steel pipe is circular arc line, needs manually to align onto assembly line, at stacking, then
Artificial decoupling device, hook.Due to not being special purpose crane, the low efficiency of handling petroleum steel pipe.
Summary of the invention
The gantry that petroleum steel pipe is carried on pipe laying barge is single main beam structure.
On girder upper cover plates top, 4 sets of independent lifting mechanisms are arranged, according to the different weight and difference of petroleum steel pipe
Length combination uses: when lifting binodal pipe, 2 sets of lifting mechanisms on the outside of use, 2 sets of intermediate lifting mechanisms follow movement；It rises
When hanging 1 single-unit pipe, using 2 sets of lifting mechanisms of side, 2 sets of lifting mechanisms of the other side are in parking position；Lift by crane 2 lists
When saving pipe, combination of two uses 4 sets of lifting mechanisms.
Special hanger of the crane equipped with lifting petroleum steel pipe.It has 2 kinds of structure likeness in form: single-unit pipe suspender, binodal pipe
Suspender.Single node suspender is made of extensible canopy, hanger beam, hydraulic station, storage cable basket, lifting pin shaft；Binode suspender is by stretching
Beam, hanger beam, hydraulic station, storage cable basket, lifting pin shaft, loop-hook composition；
In the outer gear two sides of gantry, along large vehicle walking direction, it has been laid with to total travel two column teeth on a ship 's
Item provides power, gear driving, linear motion by two sets of independent traveling mechanism of the larger traveller.
Because ship is ceaselessly being waved, rotated, rain-slicked is added, for the normal operation for guaranteeing big mechanism of car, must be adopted
With gear-rack drive form.Cart wheel is only responsible for the self weight of carrying complete machine and load.In the gantry of land work
It is all that cart wheel also serves as driving wheel and bearing wheels.
Ship waves and rotates the unstability that can increase crane.To prevent crane in extreme circumstances from inclining
It covers, the safety door hook of trade shape is additionally arranged between bogie frame and track.When installation, safety door hook wants longitudinal sleeve in cart track
On.
The beneficial effects of the utility model are: since big mechanism of car is gear-rack drive, linear motion, along with use
Special hanger, so that the working efficiency of the crane greatly improves.Also pipe laying efficiency has been correspondingly improved.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing.
Fig. 1 is the gantry that petroleum steel pipe is carried on pipe laying barge.Fig. 1 .1 is that main view, Fig. 1 .2 are side view, figure
1.3 be top view, Fig. 1 .4 be partial enlarged view, Fig. 1 .5 be partial enlarged view.
1 girder；2 lifting mechanisms；3 binodal pipe suspenders；4 binodal pipes；5 rack-and-pinion；6 traveling mechanism of the larger traveller；7 bogie frames；8
Safety door hook；
Fig. 2 is single-unit pipe suspender.
1 extensible canopy；2 hanger beams；3 hydraulic stations；4 storage cable baskets；5 lifting pin shafts；
Fig. 3 is binodal pipe suspender.
1 extensible canopy；2 hanger beams；3 hydraulic stations；4 storage cable baskets；5 lifting pin shafts；6 loop-hooks；
Brief description: extensible canopy (1) is slided hanger beam (2) is inner, provides power by hydraulic station (3)；Store up cable basket (4) storage
Deposit cable；
Lifting pin shaft (5) is protruded into inside binodal pipe and is hooked, and is herein main lifting point；Loop-hook (6) rotation is stretched out, hook
Firmly in the middle part of binodal pipe, prevent in the middle part of binodal pipe due to excessive sag caused by being self-possessed.
Specific embodiment
Can be seen that install in figure from Fig. 1 .1 is binodal pipe suspender (Fig. 3).It can be according to requiring change the outfit 2 sets (or 1 sets)
Single-unit pipe suspender (Fig. 2).Can be seen that cart wheel from Fig. 1 .2 is driven wheel, plays the self weight of support crane and load weight
Amount effect.It can be seen that four groups of lifting mechanisms from Fig. 1 .3 to be arranged on girder (1) by a shape.From partial enlarged view (figure
1.4) as can be seen that gear, the rack gear of traveling mechanism of the larger traveller.From partial enlarged view (Fig. 1 .5) as can be seen that traveling mechanism of the larger traveller
On safety door hook, hook up to cart track, notch geometry is identical to cart track cross-sectional shape.Petroleum steel pipe special hanger
There are 2 kinds --- single-unit pipe suspender, binodal pipe suspender, they can determine lifting pin shaft on height and position by sensor
It is automatically aligned to the automatic inner hole center of petroleum steel pipe；Lifting pin shaft is protruded into after petroleum steel pipe inner hole reaches specified position and is automatically stopped；
Lifting mechanism promotes steel pipe.
Fig. 2 is the detailed figure of single-unit pipe suspender.
Extensible canopy (1) is slided hanger beam (2) is inner, provides power by hydraulic station (3)；It stores up cable basket (4) and stores cable；It rises
It revokes axis (5) to protrude into inside binodal pipe and hook, is herein the lifting point of single-unit pipe；
Fig. 3 is the detailed figure of binodal pipe suspender.
Extensible canopy (1) is slided hanger beam (2) is inner, provides power by hydraulic station (3)；It stores up cable basket (4) and stores cable；It rises
It revokes axis (5) to protrude into inside binodal pipe and hook, is herein the main lifting point of binodal pipe；
Functionally, binodal pipe suspender is provided with loop-hook (6) than single-unit pipe suspender more, after suspender slings binodal pipe,
Loop-hook rotation is stretched out, and the bottom in the middle part of binodal pipe is hooked, and intermediate 2 groups of micro- raisings of lifting mechanism are born herein to assist lifting point
Binodal tube portion weight is carried on a shoulder pole, prevents binodal pipe middle part downwarp is excessive from causing to lift by crane pin shaft from nozzle abjection.
The specific mounting means of complete machine is:
1. firstly, making gantry.
2. secondly, having set 2 rack gears on pipe laying ships main deck upper berth.
3. again, installing the safety door hook between cart and track, cart driving gear.
