Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, well workover distance controlling pneumatic spider mainly includes 2 part of well head air spider and control system.
Air spider includes 3 part of housing assembly, slips assembly and cylinder assembly.Housing assembly is mainly by chuck door, door
Pin and chuck housing composition；Slips assembly is mainly made of card tooth, backing pin, auxiliary slips, slips pin, torsional spring and power slip；
Cylinder assembly is mainly by gland seal assembly, piston assembly (piston rod, piston, sealing ring), the gentle pipe joint group of cylinder block
Into.
The offside of cylinder engine chuck door in housing, axis is parallel with the inner conical surface of housing, to ensure that piston rod exists
From the effect of bending force in the course of work.Slips assembly is made of 1 power slip, 2 auxiliary slips and several groups of card teeth,
It is fitted together by axis pin, torsional spring, top is tightened in the upper end of piston rod with clamping nut.The comprehensive mechanical property of card tooth with
The contact area of flute profile, Ka Ya and tubing string is an important factor for considering in design, and what it not only determined chuck clamping tubing string can
By property, but also determine card tooth to the injury size of tubing string and the working life of card tooth.
After connecting source of the gas, slips assembly moves up and down with piston rod, and when uplink opens, and tubing string can pass through from chuck；
Shunk during downlink, card tooth hold tightly tubing string be seated on the inner conical surface of chuck housing after clamping, can on well head carries out, shackle or
Other operations.
The action of control system Electromagnetic Control technical controlling air spider, is mainly changed including pneumatic triple piece, manually
It is received to valve, solenoid directional control valve, manual ball valve, various control pipelines (gas pipeline, cable), floor push, remote controler, signal
Device etc..
Consider the actual needs of various accidents in processing well workover work progress, devise foot-operated control and remote control
2 kinds of modes of operation.Foot-operated control is to be opened by manipulator in workover rig driver's cabin by foot-operated
Pass makes electromagnetic switch valve events, changes the inlet and outlet direction of cylinder to control the action of chuck.Remote control is well head behaviour
Author sends signal at well site (in the range of 30m) by remote controler, and solenoid directional control valve is transmitted a signal to by signal receiving device,
Change the inlet and outlet direction of cylinder to control the action of chuck.It can switch mutually between 2 kinds of modes of operation.
Gas circuit is connected, opens the total valve at workover rig gas bag, air-flow reaches reversal valve, and (hand-operated direction valve, electromagnetism change
To valve), chuck should be at gripping orientation at this time, i.e., in piston rod retraction cylinder, otherwise, exchanges the position of the upper and lower gas pipeline of cylinder
It puts.
Floor push is stepped on, electromagnetic switch valve events make cylinder lower pipelines air inlet, upper pipeline exhaust；Air-flow promotes
Piston stroking upward drives slips assembly to leave housing inner conical surface, unclamps tubing string, carries out rountrip.When needing to block tubing string, lift
Floor push, solenoid directional control valve change the inlet and outlet direction of cylinder simultaneously, make cylinder top air inlet lower exhaust, and air-flow promotes
Descent of piston, drive slips assembly be seated on housing inner conical surface, after clamping tubing string, well head can set out elevator, on unload pipe thread or
Carry out other operations.
Signal-controlled switch is switched to remote control control direction, presses " clamping " button, electromagnetic switch valve events make vapour
Cylinder top air inlet lower exhaust, air-flow promote descent of piston, and slips is driven to sit people's enclosure interior clamping tubing string." release " is pressed to press
Button, solenoid directional control valve commutation, air-flow promote piston driving slips uplink to unclamp tubing string, have carried out, lower operation.
2 sets of backup circuit breakers are designed in control system：When the manual reverse of direction button above solenoid directional control valve, when electromagnetism changes
During to valve cisco unity malfunction, manually it can make electromagnetic switch valve events by force by change-over key, after completing necessary operation,
Solenoid directional control valve is carried out maintenance or is replaced；Second is that have hand-operated direction valve, when solenoid directional control valve and manual reverse of direction button all
During cisco unity malfunction, 2 manual ball valves on hand-operated direction valve outlet line can be opened, close electromagnetic switch valve outlet tube
The action of 2 manual ball valves on line, manually the handle control air spider of reversal valve, it is right after completing necessary operation
Solenoid directional control valve is carried out maintenance or replaced.
Winter gas pipeline internal water accumulation frozen block in order to prevent, is mounted with pneumatic triple piece at main pipe line, and oil storage cup is built-in
There is a certain amount of machine oil, the impurity such as the moisture in gas can not only be made to precipitate discharge in oil storage cup, prevent pipeline frozen block, and
And a small amount of machine oil can be automatically drawn into during each air inlet in gas circuit and cylinder, keep lubrication in gas circuit and cylinder.
Gas is controlled to derive from the gas bag of workover rig, when workover rig works, the operating pressure of pneumatic system is generally 4 ~ 6MPa
(different and different with workover rig model), as long as the pressure of workover rig pneumatic system is not less than 3 MPa, air spider can be just
Often action.
