Description
Technical field
The invention belongs to petroleum well workover equipment technical fields, more particularly, to a kind of hybrid power type workover rig.
Background technology
The action of workover rig is to put forward the one column column of casing of underground, and another column column is put into well after being dredged
In.This just needs roller rotation to draw high big hook to run up 10 meters or 20 meters, propose a column sleeve pipe.Then it stops and lays down casing,
Roller rotates backward lower amplification hook to well head to promote next casing again.In this process, in only big hook uphill process
The big load of full power is needed, is to carry out locking roller by brake in stopped process, power need not be provided it again, and is being transferred
In the process, gravity acting is controlled using brake.I.e. in whole process only above carry during need provide power, other when
Between power need not be provided.Meanwhile existing workover rig, using machine driven system, operation principle is to start chassis
The power of machine is converted to the lifting that hooks greatly by transmission device to propose and be put into well oil pipe.Transmission process is sent out from chassis
Then motivation power taking drives roller rotation through transmission shaft to gear-box again by transmission shaft to fluid torque-converter.Fully rely on chassis
Engine is as power source, it is desirable that vehicle-mounted card in one's hand engine power must satisfy equipment full power operation, waste the throwing of equipment
Enter；In addition all using fuel oil as fuel, the consumption of fuel oil is high, wastes fuel oil；And by control engine in situ come
Realize that the start and stop of equipment are unfavorable for Optimal Control System, big multi-state is required to operating personnel's manual operation, some operations are complete
By the experience of operating personnel and the accuracy of feel, so the requirement to operating personnel is excessively high.
Invention content
