Description
Technical field
The utility model belongs to mechanical engineering technical field, particularly a kind of hydraulic lifting apparatus that is used for the oilfield Operating Pressure.
Background technology
Oil well Operating Pressure lifting appliance is a requisite key equipment in the oilfield operation process, is used for the lifting of pressing oil well oil pipeline maintenance process, is pressed into.At present the lifting appliance that uses is by being installed in hoist engine on the heavy-duty car chassis, console, fuel tank, highly being that 30 meters hoisting frame etc. is formed.For example the oil well Operating Pressure lifting appliance of Jinan Pu Zico skill development company production is produced according to said structure.The subject matter that exists is: package unit complex structure, cost height, and, seriously restricting the production of oil well Operating Pressure because the workover process is longer.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, cost is low, need not the hydraulic lifting apparatus of the novel oil well Operating Pressure of hoist engine, hoisting frame.
The utility model is achieved in that novel oil well Operating Pressure hydraulic lifting apparatus, comprises motor, gearbox, hydraulic pump, fuel tank, hydraulic cylinder, base, hydraulic oil pipe, console, accumulator group; Motor links to each other with hydraulic pump through gearbox, and motor, fuel tank, accumulator group, console are fixed on the base; It is characterized in that the utility model also comprises three cylinder synchronized splitter devices and plug-in mounting control valve group, the utility model has three hydraulic cylinders, hydraulic cylinder is connected with plug-in mounting control valve group, three cylinder synchronized splitter devices, console, accumulator group through hydraulic oil pipe, hydraulic cylinder body is fixed on the lower transverse beam, hydraulic cylinder piston rod links together by top rail, top rail connects mobile slips simultaneously, mobile slips clamps the oil pumping oil pipe, and the rise and fall by hydraulic cylinder realize the lifting of oil pumping oil pipe respectively and are pressed into action.
Above-mentioned novel oil well Operating Pressure hydraulic lifting apparatus is characterized in that three hydraulic cylinder distributions triangular in shape, and respectively there is an overflow valve in three exits of three cylinder synchronized splitter devices, and the outlet of overflow valve and three cylinder synchronized splitter devices is connected in parallel.
Because the utility model has adopted the motor driven hydraulic system and has finally realized the synchronous lifting of three hydraulic cylinders, machine volume and quality have been significantly reduced, leg-of-mutton arrangement mode has improved the stability of complete machine greatly, the use of plug-in mounting control valve group, satisfied system high pressure, the requirement of flow greatly, the use of synchronized splitter device has improved the synchronization accuracy of three hydraulic cylinders greatly.
