Description
Technical field:
The utility model is related to a kind of hydraulic pressure pipe slips control system.
Background technology:
Operating Pressure equipment has carried out large-scale popularization in international and national oil field operation, and hydraulic pressure pipe slips are bands
One of key equipment of pressure implement, the service behaviour of slips and control security directly affect the peace of whole Operating Pressure
Entirely.When carrying out rotary operation, commonly used mechanical system locks oil pipe to domestic Operating Pressure equipment, does not adopt hydraulic pressure at present
Slips locks oil pipe, and the locking of service-strong hydraulic pressure pipe slips can reduce operation intensity, improve operating efficiency；Operating personnel operates
Slips commonly used mechanical anti-misoperation operation device is carrying out anti-misoperation or to realize safety by operating personnel quality itself completely
Operation, mechanical device install complicated, operation process sometimes for when opening two slips it is necessary to dismounting mechanical device could be real
Existing, greatly increase working strength and reduce operating efficiency, and these uncontrollable factors also increase slips maloperation and produce
The probability of security incident；State's internal slip controls the generally not pressure punching when load end uses control valve to reduce slips cylinder efficient
Hit, compression shock leads to cylinder seal to damage oil leak, control pipeline situations such as shake, if slips oil cylinder occurs in operation process
Damage and undiscovered, lead to clamp oil pipe fly out or the well head that drops, severe safety accident may be produced.
Content of the invention
The purpose of this utility model is to provide a kind of hydraulic pressure pipe slips automatic logic control system, this system, and this system is real
Showed hydraulic pressure pipe slips use safe efficient, this system does not need mechanical slips, mechanical anti-misoperation operation device in Operating Pressure
Deng it is possible to automatic defect preventing operation logic controls, improve slips service life and reliability.
The utility model is to be attained in that by following technical solution
A kind of automatic logic control system of hydraulic pressure pipe slips, including the oily control unit of lock, regulator control block, automatic logic control
Unit processed, automatic logic control element is arranged on oil circuit b and d；The automatic logic control element in left and right two passes through oil circuit control
X1, x2 connect, and for controlling selectively unlocking and the closing of slips one and slips two, regulator control block is arranged on four oil circuits
On a, b, c, d, for controlling the pressure stability of slips one and slips two, four lock oil control units are connected to regulator control block
And two slips between, for self-locking after slips oil-break.
Two hydraulic control one-way valves are had, two hydraulic control one-way valves are arranged in juxtaposition in the same direction in the oily control unit of lock.
Two direct action type voltage regulation overflow valves, two direct action type voltage regulation overflow valve reverse parallel connection arrangements are had in regulator control block
On oil circuit.
The utility model compared with prior art has the advantages that:
1st, the utility model solves the problems, such as hydraulic pressure pipe slips oil circuit control pressurize, can in Operating Pressure equipment rotary operation
With clamp tubing spinning using hydraulic pressure pipe slips and without mechanically fixing；
2nd, the utility model solves the problems, such as that current slips does not enable automatic defect preventing operational control, by automatic logic
Control valve group can be implemented in operation process will not open simultaneously two slips lead to oil pipe to fly out or the well head that drops accident；
3rd, the utility model solves the hydraulic pressure impact impact that hydraulic pressure pipe slips bring because high frequency time works at high speed, leads to
Cross the high-speed response of direct action type voltage regulation overflow valve, reduce impact peak value, reduce the impact to hydraulic valve piece for the compression shock, reduce because
The hydraulic line joint that compression shock leads to trembles.
Brief description:
Fig. 1 is the utility model block diagram.
Specific embodiment:
Below in conjunction with the accompanying drawings and embodiment the utility model will be further described.
Referring to Fig. 1, the rodless cavity of two three position four-way directional control valve actuator ports and slips one and slips two oil cylinder and have bar
Chamber hydraulic fluid port is connected by oil circuit respectively, forms tetra- oil circuits of a, b, c, d, and two automatic logic control elements are arranged on oil circuit b and d
On, connected respectively by oil circuit control x1, x2 between two automatic logic control elements.Oil circuit control x1, x2 are respectively left and right
Automatic logic control valve pilot control part in the automatic logic control element on both sides couples together, when slips is opened, b oil
Road high pressure, pressure cut off c oil circuit, lead to second slips cannot close, if necessary to open two slips simultaneously, then need certainly
Hand-operated direction valve in dynamic logic control element returns middle position, and d oil circuit recovers normal, and slips can be opened, and vice versa.Voltage stabilizing control
Unit processed is arranged on four oil circuits a, b, c, d, and in slips one and slips two action launching, slips oil cylinder moment starts generation
Hydraulic shock power obtain weakening to normal operating value in regulator control block；Four lock oil control units are connected to voltage stabilizing control
Between unit and two slips, when lock oily control unit, the hydraulic control one-way valve in the oily control unit of lock is normally-open for oil circuit,
During cut-out oil circuit, oil circuit is closed, and realizes lock functional oil.
There are two hydraulic control one-way valves to be arranged in juxtaposition in the same direction in the oily control unit of lock, and take mutually other side's inlet pressure to be
Pilot pressure.Control unit is path to slips direction, reversely closes, and when a road oil circuit control pressure reaches setting value, leads to
Cross pilot pressure and open an other road oil return, when oil circuit pressure is less than setting value, oil circuit is closed.
Automatically logic control element hydraulic control bi-bit bi-pass reversal valve and check valve are arranged in parallel, and realize oil circuit one direction and select
Property control.And take mutually other side's oil-out pressure to be pilot pressure.Realize slips one and the action of 2 two loads of slips is patrolled
Collect and control, two slips can simultaneously close off, but after opening a slips, another one slips logic control element is because of elder generation
Lead pressure cut off oil circuit can not open.
Two direct action type voltage regulation overflow valve reverse parallel connections are had to be arranged on oil circuit in regulator control block.Slips oil cylinder rodless
Chamber is connected with two direct action type voltage regulation overflow valve oil circuits respectively with rod chamber two ends, no matter being that slips is closed or unlatching can be real
Existing voltage stabilizing function.Within opening to closed mode time only about 0.2-0.5s, the fastest shut-in time reaches 0.1s, in volume to slips
When determining the work of operating pressure 1500psi, the compression shock that moment produces reaches more than 2000psi, high-frequency pressure through calculating
Impact does not only result in the minimizing of hydraulic part life-span, and instant impact leads to slip insert to collapse tooth, the lost of life, and slip insert is slips
The critical component of clamping oil pipe, the minimizing that slip insert clamps the number of teeth can lead to the dangerous situations such as oil pipe skidding to occur.
