Abstract
A fully-hydraulic-pressure-driven wheeled well-rig consists of a motor (1), a torque converter and geared oil pump (2), a roller spindle oil hydraulic motor (3), a roller operating device (4), a distributing valve (5), an accumulator (6), a hydraulic swivel head (7) and a driving device (8). The utility model is arranged with the torque converter and geared oil pump and the accumulator at the back of the motor. The oil hydraulic motor is arranged on a roller axle. A geared oil pump is arranged on a braking wheel net. The oil hydraulic motor is arranged in front of a compensating gear of a driving axle. Any mechanical driving device is canceled except the valve and a pipeline used for a fluid drive and thus a full hydraulic wheeled well-rig is formed, which, applying modern hydraulic pressure technology, is fully driven by hydraulic pressure, is simple in structure, favorable for the enlargement of a roller device and the improvement of total vehicle performance and adaptable to the demands of greatly variable load and low rotating speed. The potential energy released from hanging load can be recyclable and save thirty-five percent of energy. A hydraulic swivel head can be attached to the device, which can lessen the abrasion of the roller-braking wheel net and prevent the well mouth from being smashed and underground accidents from happening as well.
Description
The utility model relates to the tractor hoist that uses on a kind of oilfield, particularly a kind of all-hydraulic wheeled tractor hoist.
Existing tractor hoist is to grow up on the basis of bulldozer or loader.These types all are by the gearbox step speed change, make transmission of power arrive cylinder apparatus for work or driving force bridge.There do not have a kind of type to leave to be mechanically operated.Some type is a hydraulic machine drive technology of having transplanted U.S.'s workover rig, but do not cancel machine driving yet, mechanisms such as transfer case, hydraulic mechanical transmission box, the whole deceleration of mechanical type are all arranged, because forward and backward is frequent during workover treatment, load variations is big, energy when travelling block is transferred can not reclaim, and exists a large amount of energy wastes.
The purpose of this utility model is to provide a kind of all-hydraulic wheeled tractor hoist, simplifies transmission mechanism, reduces manufacturing cost and mechanical wear.Particularly reduce the wearing and tearing of drum brake wheel net, reduce the fault of dividing headstock and gearbox, store and the energy when utilizing travelling block to transfer energy conservation.
The purpose of this utility model is to realize like this, it is by motor (1), fluid torque-converter and gear oil pump (2), drum shaft hydraulic motor (3), cylinder apparatus for work (4), distributing valve (5), accumulator (6), hydraulic swivel head (7), travel driving unit (8) is formed, being connected with fluid torque-converter on motor (1) in turn reaches and gear oil pump (2), distributing valve (5), distributing valve (5) respectively with drum shaft hydraulic motor (3), hydraulic swivel head (7), travel driving unit (8) connects, drum shaft hydraulic motor (3) and cylinder apparatus for work (4), accumulator (6) connects.
When work, power and moment of torsion that motor produces through fluid torque-converter and gear oil pump, become the hydraulic pressure energy.System reaches distributing valve by the road, is divided into the two-way of interlocking: walking and cylinder apparatus for work.
During walking, the power of motor is converted into the hydraulic pressure energy through fluid torque-converter driven gear oil pump.Hydraulic oil makes the hydraulic motor before hydraulic pressure can be delivered to drive axle through distributing valve, pipeline system.This hydraulic motor work drives the tractor hoist walking.
When carrying out workover treatment, the power of motor is converted into the hydraulic pressure energy through fluid torque-converter driven gear oil pump.Hydraulic oil is through distributing valve, pipeline system, makes hydraulic pressure can be delivered to hydraulic motor on the drum shaft.This hydraulic motor work, drive roller shaft rotation, thereby the upper and lower motion of realization travelling block.
In the up course of work of travelling block, the energy of motor is converted into the potential energy of travelling block suspending weight.In the descending course of work of travelling block, the potential energy of travelling block suspending weight is converted into the kinetic energy of cylinder rotation.
The utility model owing to adopted behind motor is installed fluid torque-converter and gear oil pump, accumulator.Hydraulic motor is installed on drum shaft.At the online gear oil pump of installing of drum brake wheel.Before the differential mechanism of drive axle, hydraulic motor is installed.Except being used for hydraulicdriven valve, pipeline, cancel any mechanical driving device, form the tractor hoist of all-hydraulic transmission, use modern hydraulic technology, all-hydraulic transmission, simple in structure, be beneficial to the increasing of drum apparatus and the raising of vehicle performance, it is big to adapt to load variations, the requirement that rotating speed is little.The potential energy that suspending weight is transferred, recyclable utilization, energy-conservation 35%.Can attach hydraulic swivel head.Reduce the wearing and tearing of drum brake wheel net, can prevent to pound well head and down-hole accident again.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in the figure, the utility model is made up of motor 1, fluid torque-converter and gear oil pump 2, drum shaft hydraulic motor 3, cylinder apparatus for work 4, distributing valve 5, accumulator 6, hydraulic swivel head 7, travel driving unit 8, and fluid torque-converter and gear oil pump, accumulator are installed behind the motor.Hydraulic motor is installed on drum shaft.At the online gear oil pump of installing of drum brake wheel.Before the differential mechanism of drive axle, hydraulic motor is installed.The potential energy of the suspending weight when travelling block is descending is converted into the kinetic energy of cylinder rotation.This kinetic energy is converted into hydraulic pressure through gear oil pump and can be stored in the accumulator, and when travelling block was up, the hydraulic motor of the energy in the accumulator on drum shaft was converted into the rotation function of cylinder, realizes the up of travelling block, finishes the oil pipe suspending weight task that promotes.By the transmission of distributing valve control energy, transfer energy and reclaim the effect that gear pump has the auxiliary cylinder brake, after energy stores simultaneously, be used for hydraulic tubing tong.Distributing valve is connected with hydraulic swivel head, travel driving unit, can drive the milling tool that hydraulic swivel head carries out the down-hole, and travel driving unit can drive the motion of car simultaneously.
