Description
Technical field
The utility model belongs to the improvement of oil field automation workover rig pipe elevator equipment, particularly a kind of automatic workover rig
The special elevator of oil pipe.
Background technology
Oil well repairing operation is the important step of oilfield stable production, high yield, its groundwork has：Inspection pump, sand control, adjust layer, penetrate
Hole, change envelope, bring in a well, and very hard work is exactly lower oil tube, sucker rod and downhole tool for one of them.Rise at present
Lower operation relies primarily on Manual Switch oil pipe（Sucker rod）Elevator, dislodging hanging ring, push and pull hydraulic tongs, push away and put jigger, auxiliary oil
Pipe positioning etc..Traditional operating type does not require nothing more than operating personnel's energy high concentration, and it is flexibly accurate that action coordinates, and operates
Frequently.Unsafe factor is more, and operation danger is larger, and most of well head personal injury accident is all due to that well head operation is matched somebody with somebody
Close it is improper caused by.Labor strength is big and operating efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of special elevator of automatic workover rig oil pipe, its is rational in infrastructure, performance peace
It is complete reliable, it is possible to achieve to be matched with automatic workover rig, solve automatic snatch oil pipe, reduce labor strength, improved and make
Industry efficiency.
What the purpose of this utility model was realized in：The special elevator of a kind of automatic workover rig oil pipe, in special elevator base
The symmetrical suspended axle that seat front and rear sides is set is engaged with two symmetrical earrings that travelling block is set, and is set in the middle part of two earrings
Articulated dump ram in the fixed seat put, its piston rod end is hinged with the hinged seat set on the right side of pedestal, in pedestal
Open slot, centre bore and oil pipe clearance fit are set on the left of heart hole, in its piston of the affixed moving cylinder of pedestal lower horizontal
The articulated valve locking device in bar front end, valve locking device are hinged by valve lock pin with pedestal, the work of valve locking device
Door catch is engaged with the fixture block of pedestal, and the fixture block of valve locking device is matched by the open slot in base central hole with oil pipe
Close.
Utility model works principle：
1st, elevator uses the elevator of suspended axle for both sides, hangs on two auricular appendage ring lower ends.
2nd, tilt cylinders are fixed in the middle part of two auricular appendage rings by horizontal fixed plate, piston rod connection elevator back connecting seat,
When cylinder piston rod is stretched out, retracted, elevator lower end edge suspended axle is rotated clockwise, retracted, and is adjusted according to the angle of oil pipe
Section, clasps oil pipe.
3rd, after oil pipe enters elevator, valve cylinder promotes valve to be rotated along valve pivot pin, closes, and valve lock pin is locked automatically
Extremely.
When the 4th, needing to open valve, the air inlet of pipe fitting position, the linkage of promotion valve lock pin, after making valve lock pin
Move back, unlock, valve cylinder piston rod is withdrawn, and valve can be opened.
The utility model liquid rises pressing tongs under cylinder action, and higher than tubing coupling position, manipulator will be close to well head
Oil pipe catch, lift, upper end is hung in elevator, lower end insertion well head, during upper button manipulator unclamp.
The utility model is rational in infrastructure, and performance safety is reliable, realizes and is matched with automatic workover rig, solves automatic
Snatch oil pipe, reduces labor strength, improves operating efficiency.
