Description
Technical field
The utility model relates to equipment---the multi-functional swing pipe machine of a kind of long distance pipeline lifting, transportation, welding.Multi-functional swing pipe machine is body with the crawler doer, installs that folding type hydraulic hangs, Hydraulic Equilibrium Mechanism, alternating current generating sets, hydraulic pressure pipe fixer, arc welding electrical supply form.Integrate lifting pipes, fork tubulature, conveying pipes, mucking, welding pipe function.Therefore, this car not only can be used as hanging device and uses, and also can be used as multi-functional preparation of construction and uses, and also can be used as the miniwatt portable power source and uses.In hydraulic and electric engineering, petrochemical enterprise field pipeline system install, substantial value of service is arranged.
Background technology
Hydraulic and electric engineering, petrochemical enterprise pipeline are assembled in the open air and are welded with two kinds of forms of construction work.A kind of is assembling welding on the pipe trench: the pipe preliminary election is placed on by the pipe trench, with hanging device pipe lifting assembling welding is formed long distance pipeline, at the bottom of lifting by crane a segment pipe simultaneously and place it in pipe trench with many hanging devices more than 45 tons again.Another kind is assembling welding under the pipe trench: at the bottom of the pipe preliminary election is placed on pipe trench, in pipe trench, lift by crane pipe again with lifting appliance, the assembling welding pipe forms long distance pipeline in pipe trench, after the assembling welding pipeline is placed directly at the bottom of the pipe trench, only needs many hanging devices below 10 tons to lift by crane a segment pipe.
Hydraulic and electric engineering, the installation of petrochemical enterprise plumbing system, majority is that complex-terrains such as mountain region, hills, desert, loess tableland carry out in the open air, the pipe hanging device generally adopts laying tractor, and the pipe vehicle equipment adopts homemade simple and easy skid cargo carrier.
Because the arm of laying tractor is installed in the side of body, balance weight is installed on the hydraulic pressure ejecting mechanism of body opposite side, and there is the deficiency on the in-use performance in the laying tractor of this physical construction:
The laying tractor lifting pipes is that the gravitational moment of hoisting heavy will make laying tractor be in rollover conditions to tilting moment of laying tractor effect with the lifting of " cantilever hangs " form; The tilting moment that hoisting heavy produces makes laying tractor keep stable by the balancing torque institute balance that laying tractor has.The lifting kinetic moment of laying tractor is made of the lifting arm of force and fuselage gravity product: the distance between the center-of-gravity position of fuselage and the crawler belt limit is the lifting arm of force, and laying tractor weight and counterweight weight sum are fuselage gravity.Gravitational moment increase when hoisting heavy, hydraulic gear is released moving counterweight increases lifting moment, and can not balance lifting gravitational moment the time, the arm elevation angle only changes as lifting moment, to shorten the mode of lifting weight arm vertical length, reduce the lifting gravitational moment that hoisting heavy produces.But change the arm elevation angle and shorten lifting weight arm vertical length, can make the pipe of lifting can not arrive predetermined installation site again.Because the lifting moment of laying tractor is fixed value, along with the increase of hoisting heavy weight, the lifting safety factor is reducing gradually, is unfavorable for safe lifting.Be safety loading and unloading pipe, the essential large-tonnage laying tractor of selecting of the lifting of little tonnage pipe.
The arm of laying tractor can not rotate, during lifting pipes, and the same side that pipe delivery facility must be put arm.In the mountain region, when undulating topography uses, be subjected to the restriction of putting position, arm can only be crossed vehicle equipment loading and unloading pipe.Because of arm and ground-surface angle diminish, it is very big that the gravity arm of force becomes, and hydraulic gear is released moving counterweight increases lifting moment, as lifting moment can not balancing gravity moment the time, be safety loading and unloading pipe, the essential large-tonnage laying tractor of selecting of the lifting of little tonnage pipe.
Main hydraulic wireline winch, the secondary hydraulic wireline winch of laying tractor are installed on the fixed frame, and the weight of main hydraulic wireline winch, secondary hydraulic wireline winch can not be as the counterweight of activity, and the weight of the just balance plate that Hydraulic Equilibrium Mechanism is released is as moving counterweight.Therefore, when the object of lifting equivalent weight, hydraulic gear is released moving counterweight to be increased when lifting by crane the moment deficiency, for safety loading and unloading pipe, can only select the large-tonnage laying tractor.
The above-mentioned method that increases lifting moment merely with the deadweight of increase laying tractor is that laying tractor is purchased fund and fuel oil consumption is a cost to increase, and exchanges not phase ratiometric raising of crane capacity for, is uneconomic technical scheme.Also there is many-sided deficiency in the use: drive the large-tonnage laying tractor, need to increase the power of diesel motor, increase energy consumption; Pipeline construction finishes, and large tonnage crawler pipe sling transition traffic requirements large-tonnage flat-bed trailer increases the pipeline construction auxiliary expenses; In the mountain region, undulating topography construction, the interim construction road of build is the walking that guarantees the large tonnage crawler pipe sling, must build crash-resistant construction road, increases the pipeline construction auxiliary expenses.
