For the functional unit in converter, then power supply is directly connected with motor 3 by converter;
And described power supply is electrically connected with the accumulated energy flywheel 4 in flywheel energy storage unit by described rectification unit 1
Connect, simultaneously as accumulated energy flywheel 4 has two-way inverter, so the electric current in rectification unit 1 passes through
It is internal that the conversion of two-way inverter 5 is just flowed into accumulated energy flywheel 4, and accumulated energy flywheel 4 is by two-way inverse simultaneously
Become device also to electrically connect with inversion unit 2;
This device also includes cylinder 6 and derrick unit, and cylinder and derrick unit all place be arranged on for
On workover rig, described motor 3 for cylinder 6 provide rotational power, described derrick unit include hook 7,
Hydraulic cylinder 8, the upright pylon 9 being vertically arranged on workover rig chassis and be folded on workover rig chassis
Derrick 11, described hook 7 is rotated by cylinder 6 and is subjected to displacement, and described hook 7 is arranged on derrick
On 11, described hydraulic cylinder 8 one end is articulated with workover rig chassis, and the other end is articulated with the bottom of derrick 11,
When using the electromotor on workover rig chassis to drive, by power takeoff power taking, simplify and fallen original biography
Moving axis, a series of mechanical transmission unit such as change speed gear box, torque converter, greatly reduce equipment purchasing
Expense, decreases rigging up and debugging time and fault rate.
Also needing to include supporting leg 10 on workover rig, this supporting leg 10 includes connecting the supporting leg oil having hydraulic lock
Cylinder, this hardware device improves stability and the safety of complete machine.
As in figure 2 it is shown, described workover rig chassis is provided with workover rig mounting base 12, described workover rig is pacified
Fill base plate 12 and plane-parallel, and described workover rig mounting base 12 be provided with derrick bracing frame 122,
Described derrick bracing frame 122 stands still for a long while on workover rig mounting base 12 by support bracing piece 121, because of
This derrick bracing frame 122 can bear the crunch of derrick 11, and described derrick 11 is connected to derrick and props up
On support 122, described workover rig mounting base 12 is additionally provided with hanger 123, described hydraulic cylinder 8 with hang
Ear 123 is fixing to be connected.
Described power supply is well site electrical network three phase mains and the electromotor being arranged on workover rig, described electromotor
Being connected with a power takeoff, described power takeoff passes through transmission axle driven dynamo, when having well site electrical network three-phase
I.e. as power supply when of power supply, and just can use workover rig when of without extraneous power supply
On the electromotor that carries use as power supply.
Described control system also includes that detecting motor 3 actually enters the detection module of power.
The power of above-mentioned well repairing device provides method, and its concrete steps include:
The first step, control system judges whether to need power supply output power, when needs power supply output power then
Carry out second step, otherwise enter into the 6th step;
Second step, control system controls power supply to be provided for motor 3 by rectification unit 1 and inversion unit 2
Power;Power supply drives accumulated energy flywheel 4 energy storage by rectification unit 1 and two-way inverter 5 simultaneously;
3rd step, control system is supplied to electricity also by detection module detection electric current after inversion unit 2
The input power of machine 3;
4th step, then continues the confession of second step less than power supply when the power that the input power of motor 3 provides
Power mode, otherwise enters the 5th step;
5th step, accumulated energy flywheel 4 stops energy storage and provides electricity by two-way inverter 5 for inversion unit 2
Can, this electric energy is provided for motor 3 together with power supply by inversion unit 2 and runs power, meanwhile holds
The continuous detection performing second step;
6th step, in the described first step, control system judges when motor 3 need not provide electric power, institute
Stating control system stops power supply to provide electric power for motor 3, turns when motor 3 occurs and provides electric power with power supply
When contrary rotation, this motor 3 is carried for accumulated energy flywheel 4 by inversion unit 2 and two-way inverter 5
For energy storage energy.
Detection module in described control system also detects the angular velocity of accumulated energy flywheel 4, and passes through formula:
W=0.5J ω2Calculate the storage energy of accumulated energy flywheel 4, wherein J: rotary inertia, ω: accumulated energy flywheel
The angular velocity of 4.Because the storage energy measuring of accumulated energy flywheel 4 is convenient, so can be to accumulated energy flywheel 4
Carry out monitoring in real time and occur for equipment such as alarm, especially accumulated energy flywheel 4 or power supply, motor 3 etc.
Fault, thus the when of causing accumulated energy flywheel 4 can not realize energy storage, we just can be according to the storage of detection
Deposit energy and grasp this kind of situation in time.
The operation principle of this well repairing device:
By putting forward of the sleeve pipe one post post of down-hole, after dredging another post post put in well, this is just
Need cylinder 6 rotation to draw high hook 7 and run up 10 meters or 20 meters, propose a column sleeve pipe, then stop
Under lay down sleeve pipe, cylinder 6 rotates backward again transfers hook 7 to well head and promotes next root sleeve pipe.
Only have in hook 7 uphill process in this process and need the big load of full power, in stopped process
It is to carry out locking cylinder 6 by brake gear, it is not necessary to provide it power again.And in decentralization process gravity
Acting, uses brake to control, so needing to provide power during carrying on only having during whole, its
He all need not provide power the time.
Control system detects the when of needing power supply to power, and power supply transfers direct current to through rectification unit 1 and divides
Do not go to inversion unit 2 power for motor 3 and drive accumulated energy flywheel 4 to carry out energy storage through two-way inverter 5,
In the time of the input power required for power is more than motor 3, accumulated energy flywheel 4 persistently stores up
Can, and upper carry need full power export time, by power and the merit that stores of accumulated energy flywheel 4 of power supply offer
Rate is supplied to motor 3 together, and accumulated energy flywheel 4 now exports energy by two-way inverter 5 to motor 3
Amount so that motor 3 is operated at full capacity, thus improves the efficiency of lifting heavy.
It addition, motor 3 reverse charging can carry out energy storage to accumulated energy flywheel 4 when being lowered that weight is counter to be dragged.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality
Type, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement made
Deng, within should be included in protection domain of the present utility model.
