Abstract
The utility model relates to a movable hydraulic well testing winch which is characterized in that a counting wheel assembly and a bridge plate are connecting by a hinge, a hydraulic system is composed of a hydraulic integrated block and a reversing valve, an overflow valve and a speed regulating valve which are directly arranged on the hydraulic integrated block and are connected with corresponding pipeline interfaces, an output shaft of a hydraulic motor in a transmission system is connected with an input shaft of a three-gear speed changing box, and a rotating shaft of a roller is connected with the three-gear speed changing box. The movable hydraulic well testing winch overcomes the defect that a bridge plate or a reciprocating screw rod of the existing winch has easy deformation during working so that the normal well testing operation is affected, and the utility model eliminates the technical defects that the working quality is reduced due to the oil leakage and the oil loss of a hydraulic pipeline, and the hydraulic can not normally run. The three-gear speed changing box raises the speed of the operation of the movable hydraulic well testing winch, such as wire releasing operation, etc.
Description
The utility model provides a kind of movable hydraulic pressure well testing winch, and particularly by the cylinder that is arranged on the chassis overhang plate, the well testing winch of the driving system of rope-arranging mechanism, counting mechanism, hydraulic efficiency pressure system, fluid motor-driven belongs to lifting apparatus technical field.
The operation field of exploration, exploitation oil for cooperating parameter instrument work such as measurement well downforce temperature flow, often uses a kind of well testing winch, and this winch can be transferred to logging device in the well certain depth or it is promoted out, thereby finishes logging operation.Existing oilfield well testing winch, dependable performance, use also more convenient, can satisfy the measurement well job requirements.Not enough is that counter wheel and bridge plate are the type of being fixed as one in the transmission row silk of well testing winch.Because in the well testing operation, steel wire in the well head outlet after the well head pulley.Counter wheel, again around to cylinder, steel wire produces certain tension, can make bridge plate or the reciprocal other bending deformation of leading screw, influences normal operation.In the hydraulic efficiency pressure system, the oil pipe winding displacement is staggered, circuit is long, leakage of oil, oil leak accident happen occasionally, and the lighter pollutes operating environment, reduces the operation quality, and severe patient can cause the HM Hydraulic Motor can't normal operation, and the well testing operation can't be carried out.In addition, driving cylinder as the HM Hydraulic Motor of the propulsion source of well testing winch turns round together, the rotating speed of HM Hydraulic Motor often is the revolution of cylinder, the synchronization of this dullness changes, can not well cooperate the rope in the well testing operation or transfer the velocity variations requirement of rope, limit the performance of hydraulic pressure well testing winch work efficiency to a certain extent.
Above-mentioned deficiency at existing hydraulic pressure well testing winch technology, the purpose of this utility model provide a kind of can invar rope tension and make bridge plate or back and forth leading screw flexural deformation, influence the counter wheel normal operation, overcome better that the hydraulic circuit pipeline is long, leakage of oil, oil leak accident, and can significantly improve the movable hydraulic pressure well testing winch of winch work efficiency.
Above-mentioned purpose of the present utility model, realize by taking following technical measures:
In the movable hydraulic pressure well testing winch of being made up of the driving system that is arranged on cylinder, rope-arranging mechanism, counting mechanism, hydraulic efficiency pressure system and fluid motor-driven on the chassis overhang plate, the counter wheel assembly is connected with hinge with bridge plate; By hydraulic manifold block and directly be seated in hydraulic manifold block, constitute in the hydraulic efficiency pressure system with respective line interface bonded assembly change-over valve, by pass valve, governor valve; In the driving system, hydraulic motor output shaft and three class gear box are gone into axle and are joined, and the rotating shaft of cylinder then is connected with the output shaft of three class gear box.
Movable hydraulic pressure well testing winch provided by the utility model has overcome existing winch counter wheel and has captiveed joint with bridge plate, and the bridge plate or the reciprocal leading screw that cause producing in the work are out of shape, thereby influences the shortcoming of normal well testing operation.Compare, also got rid of because of the hydraulic power line leakage of oil with existing well testing winch, run oil and reduce working environment, quality, even the technical deficiency that HM Hydraulic Motor can't normal operation.The application of three class gear box makes in the winch operation, can be according to actual needs, adopt high and low, empty three different gears, improved operating speeds such as winch unwrapping wire, and actv. improves the work efficiency of movable hydraulic pressure well testing winch.
Accompanying drawing 1 is the structural representation of movable hydraulic pressure well testing winch provided by the utility model, accompanying drawing 2 is counting mechanism and bridge plate connecting portion organigrams of movable hydraulic pressure well testing winch, accompanying drawing 3 is hydraulic efficiency pressure system connection location scheme drawings of movable hydraulic pressure well testing winch, and accompanying drawing 4 is the interior connecting portion scheme drawings of the driving system of movable hydraulic pressure well testing winch.Below in conjunction with accompanying drawing,, further narrate technical characterictic of the present utility model by most preferred embodiment.
Movable hydraulic pressure well testing winch is made of the driving system that is arranged on cylinder (3) on chassis (1) supporting plate (2), row's silk mechanism (6), counting mechanism (8), hydraulic efficiency pressure system fluid motor-driven.Wherein, the counting mechanism (8) that has pinch roller (9) is connected with hinge (11) with bridge plate (10); In the hydraulic efficiency pressure system, change-over valve (13), by pass valve (14), governor valve (15) directly be connected with corresponding pipeline interface on the hydraulic manifold block (12); In the driving system, the input shaft of the output shaft of HM Hydraulic Motor (16) and three class gear box (17) joins, and the output shaft of three class gear box (17) is connected with cylinder (3).
In the utility model, adopt movable cylinder (3), its transmission row silk mechanism (6) is arranged on the top of cylinder (3), guide rail (4) is set below the cylinder (3), this guide rail (4) lifts at counting mechanism, receivability is because of rotation manual mechanism (5), and the axially displaced cylinder (3) of cylinder (3) that an end is connected with supporting plate (2) with movable drive coupling (7)
Claims (2)
1. a movable hydraulic pressure well testing winch is made up of the driving system that is arranged on cylinder, rope-arranging mechanism, mechanism, hydraulic efficiency pressure system and fluid motor-driven on the chassis overhang plate, it is characterized in that the counter wheel assembly is connected with hinge with bridge plate; By hydraulic manifold block and directly be seated in hydraulic manifold block, constitute in the hydraulic efficiency pressure system with respective line interface bonded assembly change-over valve, by pass valve, governor valve; In the driving system, hydraulic motor output shaft and three class gear box are gone into axle and are joined, and the rotating shaft of cylinder then is connected with the output shaft of three class gear box.
