Abstract
The utility model relates to a movable assister bar, which mainly solves the problem that the current wellhead valve is difficult and unsafe to replace, and is characterized in that the screw thread directions of a left movable rod and a right movable rod (3 and 5) are opposite, the ends with threads are connected through a movable rod bolt sleeve (4), a U-shaped left slip (2) is connected onto the left end of the left movable rod (3), a telescopic rod (6) is sleeved outside the right end of the right movable rod (5) and fixed through a telescopic rod fixing bolt (7), and the right side of the telescopic rod (6) is connected with a U-shaped right slip (8). The movable assister bar has the characteristics that the wellhead valve is convenient to replace, and the operation is simple, safe and reliable.
Description
Technical field
The utility model relates to the used auxiliary equipment of oil well on a kind of oil field, especially a kind of movable assister bar.
Background technology
The water injection well of ordinary production on the present oil field, the individual well oil pressure is all than higher, and average pressure can reach about 13.5Mpa, 250 sleeve gates that use of well well head particularly, by reason of heavy pressure, in case damage, very difficult during replacing, generally to draw with motor vehicle, wire rope, need many people's cooperation just can finish, and strength is wayward, fragilely comes sluice gate, there is potential safety hazard, brings certain difficulty to production management.
Summary of the invention
[0003] change difficulty, unsafe problem in order to solve existing well head gate, the utility model provides a kind of movable assister bar, and this movable assister bar has is convenient to change well head gate, simple to operate, safe and reliable characteristics.
The technical solution of the utility model is: a kind of movable assister bar, comprise the screwed left and right motion bar of an end, the thread rotary orientation of described left and right motion bar is opposite, and a screwed end connects by the motion bar bolt sleeve, left side motion bar left end connects the left slips that takes the shape of the letter U, right motion bar right-hand member outside is with expansion link, and fixes by the expansion link set bolt, and described expansion link right side connects the right slips that takes the shape of the letter U.
Be equipped with left and right slips set bolt on the described left and right slips respectively.
The utlity model has following beneficial effect: owing to take above-mentioned assister bar, when the dismounting gate, the U-shaped slips can be stuck in the coming on sluice gate and the master valve of well head, by rotary moveable bar bolt sleeve motion bar is stretched out to two ends, realize the expansion of well head, satisfy the space requirement of changing sleeve gate.The application of this assister bar makes the work of dismounting well head gate independently to be finished by single, has saved human and material resources; Easy for installation, need not use the thermoelectricity weldering, safer; Increase work efficiency, shortened the time of changing gate.
Description of drawings:
Fig. 1 is the structural representation of Pithead preventing thieves device in the utility model.
1-left side slips set bolt among the figure, 2-left side slips, 3-left side motion bar, 4-motion bar bolt sleeve, the right motion bar of 5-, 6-expansion link, 7-expansion link set bolt, the right slips of 8-, the right slips set bolt of 9-.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of movable assister bar, comprise the screwed left motion bar 3 of an end, right motion bar 5, and the thread rotary orientation of left motion bar 3, right motion bar 5 is opposite, left side motion bar 3, the outside motion bar bolt sleeve 4 that passes through of right motion bar 5 screwed ends connect, like this, rotate motion bar bolt 4, left motion bar 3 and right motion bar 5 just can stretch out or indentation simultaneously.Left side motion bar 3 left ends connect the left slips 2 that takes the shape of the letter U, be installed with left slips set bolt 1 on the slips 2 of a left side, right motion bar 5 right-hand member outsides are with expansion link 6, and it is fixing by expansion link set bolt 7, right motion bar 5 can stretch out in expansion link 6 or withdraw, described expansion link 6 right sides connect the right slips 8 that takes the shape of the letter U, and are installed with right slips set bolt 9 on the right slips 8.
This movable assister bar comes sluice gate and total distance of producing gate to regulate the position of right motion bar 5 in expansion link 6 according to well head earlier in use, screwing expansion link set bolt 7 fixes right motion bar 5, then with about two U-shaped slips be stuck in sluice gate and produce on the gate, tightening the slips set bolt is fixed, rotating motion bar bolt sleeve 4 again stretches out the motion bar at two ends, replaceable sleeve gate when the needs of changing sleeve gate are satisfied in the space, after replacing is finished, rotate motion bar bolt sleeve 4 more round about, can realize the well head reduction.This movable assister bar makes changes more convenient, the easy row of well head gate, does not need to increase any well head technology, equipment, has reduced workman's workload, and stable performance, safe and reliable during use, be applicable to the use of changing various well head gates, have broad application prospects.
Claims (2)
1. movable assister bar, comprise the screwed left and right motion bar (3 of an end, 5), it is characterized in that: the thread rotary orientation of described left and right motion bar (3,5) is opposite, and a screwed end connects by motion bar bolt sleeve (4), left side motion bar (3) left end connects the left slips (2) that takes the shape of the letter U, right motion bar (5) right-hand member outside is with expansion link (6), and fixing by expansion link set bolt (7), and described expansion link (6) right side connects the right slips (8) that takes the shape of the letter U.
