Description
Technical field
The utility model belongs to petroleum well workover equipment technical field, is related to a kind of detachable lifting of workover treatment with pressure
Mechanism.
Background technology
Pressure balance workover rig is for the heavy repair task of water injection well in oil fields and a kind of not " draining overflow " (work with pressure for researching and developing
Industry) novel workover rig, be widely used so far in oil, natural gas well workover field.Usual pressure balance workover rig is
It is used cooperatively with well maintenance vehicle to complete workover treatment, this workover rig for needing well maintenance vehicle cooperation to fulfil assignment is referred to as assisting
Formula workover rig.But in some actual job places, such as field mobile operation and one-shot job place, in order to reduce operating cost,
People replace well maintenance vehicle, this workover rig for having installed mast additional to be referred to as to mast has been installed additional on pressure balance workover rig, with mast
Free-standing workover rig.The structure of currently known stand alone type workover rig is directly to be installed at mast by upper and lower two free bearings to repair
Integral type derricking gear is formed on well working host, then keeps mast (arm) solid with bottom surface by upper and lower two groups of drawing anchor lines
It is fixed.But this structure workover rig has installed the centre-of gravity shift due to equipment (derricking gear), bad stability, previous after mast additional
Construction period the serious accident that this lifting appliance is blown down by strong wind just once occurred.
Utility model content
The purpose of this utility model is that being solved to problem of the existing technology, a kind of reasonable for structure, behaviour is provided
The detachable derricking gear of workover treatment with pressure that work is convenient, safety and stability are good.
The technical solution that the utility model uses is as described below：
A kind of detachable derricking gear of workover treatment with pressure, there are one connection of the lower part with adjusting supporting leg is flat for tool
Platform is uprightly connected with the arm mast of subband lifting steel cable on the table top of connecting platform by the first free bearing, hung upwards
Arm mast lower part side is provided with the second free bearing for being connect with well-repairing work host, another on the top of arm mast and lower part
Side connects respectively lifts by crane one end of steel cable equipped with fixed pulley and hydraulic wireline winch around being connected on the hinge shaft of hydraulic wireline winch, the other end around
It is connect after crossing fixed pulley for playing hanging object with outside.
With in detachable derricking gear, arm mast passes through one group of symmetrically arranged drawing anchor for above-mentioned workover treatment with pressure
Rope is bonded with the earth, plays the role of stable center of gravity.
Above-mentioned workover treatment with pressure is in detachable derricking gear, and arm mast is by two to three-level hydraulic telescopic arm structure
At the telescopic arm structure is driven by one-way cylinder, and operating time degree is fixed and locked.
Above-mentioned workover treatment with pressure is that feed screw nut type adjusts supporting leg or liquid with supporting leg in detachable derricking gear, is adjusted
The driving adjusting supporting leg of compressing cylinder.
Compared with the existing integral type derricking gear that mast is directly installed on well-repairing work host, the utility model
By the structure of discrete setting well-repairing work host and arm mast on the connecting platform for adjusting supporting leg, by arm mast
It is also secured on connecting platform and well-repairing work host, greatly strengthens the stability of device structure in this way, be effectively ensured
The safety of workover treatment with pressure and working efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of one specific embodiment of the utility model.
Fig. 2 is the fundamental diagram of the utility model.
The title of each number designation is respectively in attached drawing：1- connecting platforms, 2- adjust supporting leg, 3- arm masts, 4-
Pull anchor line, the first free bearings of 51-, the second free bearings of 52-, 6- hydraulic wireline winch, 7- fixed pulleys, 8- lifting steel cables, 9- (work
Host) drawing anchor line, 10- well-repairing work hosts.
Specific implementation mode
Referring to attached drawing, workover treatment with pressure described in the utility model is with detachable derricking gear by connecting platform 1, tune
Save supporting leg 2, arm mast 3, drawing anchor line 4 and twisted seat etc. part composition.The appearance and size of connecting platform 1 can rise according to practical
The workload of loop wheel machine structure, sling height and appearance and size of well-repairing work host 10 for being connected etc. are connected because usually determining
There is the mounting flange being connect with well-repairing work host 10 on the table top of platform 1.Supporting leg 2 is adjusted to be set under the table top of connecting platform 1,
Supporting leg or the driving adjusting supporting leg of hydraulic cylinder are adjusted for feed screw nut type；Supporting leg 2 is adjusted when work can be real in a certain range
Now height adjusts, height adjustment when being docked with well-repairing work host 10 for connecting platform 1.Arm mast 3 is used as this practicality
The arm of the novel derricking gear, for a secondary stretching structure constituted to three-level hydraulic telescopic arm by two, the stretching structure by
One-way cylinder drives, and operating time degree is fixed and locked.It is respectively provided with fixed pulley 7 on the top of arm mast 3 and following side
With hydraulic wireline winch 6, lift by crane steel cable 8 one end on the hinge shaft for being connected in hydraulic wireline winch 6, the other end bypass fixed pulley 7 after for
Hanging object connection is played in outside, realizes hoisting heavy.It it is two groups by the free bearing that linkage forms, wherein the first free bearing 51 is for connecting
Being fixedly connected between platform 1 and arm mast 3, the second free bearing 52 are used for consolidating between arm mast 3 and well-repairing work host 10
Fixed connection.Symmetrically arranged drawing anchor line 4 being bonded for arm mast 3 and the earth, plays the role of stable center of gravity, adopts
It is realized with steel wire rope and tractor.
The utility model it is reasonable for structure, easy to operate.Compared with prior art, the detachable derricking gear has been used
Free-standing workover rig, stability, safety have obtained large increase.
