Description

Valve elevator Automated condtrol mechanism

Technical field

The utility model relates to workover treatment equipment technical field, refer in particular to a kind of structure simple, there is valve elevator Automated condtrol mechanism compared with high automation degree.

Background technology

Workover treatment, refers to a kind of operation of oil drilling and follow-up well maintenance, can use smoothly in order to ensure oil well, and the care and maintenance measure taked.The feature of workover treatment is that engineering difficulty is large, and technical requirements is high, must with large-scale workover rig, and is equipped with the special equipment instrument such as overhaul drilling rod, overhaul rotating disk and just can carries out the work.Workover treatment of the prior art, modal action comprises trip-out and lower brill.Pull out of hole, as the term suggests, exactly by the drilling tool (such as oil pipe) of down-hole from well out; Lower brill, as the term suggests, exactly drilling tool is transferred in well.

Valve elevator is a part for whole oil well repairing operation equipment, because valve elevator is in a self-movement, changeable irregular operating attitude, and uncontrollable degree of freedom, unpredictable factor is brought to the operation of whole oil well, therefore, can the Automated condtrol of valve elevator realize the realization being directly connected to oil well Automated condtrol.

Utility model content

The utility model proposes a kind of valve elevator Automated condtrol mechanism, solve the Automated condtrol problem of valve elevator in prior art.

For solving the problems of the technologies described above, the technical solution of the utility model is: valve elevator Automated condtrol mechanism, comprising:

Valve open-and-close mechanism, described valve open-and-close mechanism comprises valve cylinder and elevator valve, and described valve cylinder controls the folding of described elevator valve by connecting rod;

Dead bolt, described dead bolt by dead bolt air cylinder driven, for closedown described elevator valve after pinned;

Elevator cylinder, the number of described elevator cylinder is two and is arranged in series, for controlling the posture of described elevator.

Preferably, described connecting rod is with auto-lock function.

The beneficial effect of the utility model after have employed technique scheme is: the valve elevator Automated condtrol mechanism of this utility model is under the prerequisite not changing valve elevator performance, especially the security performance of valve elevator is not changed, its Automated condtrol is realized under the drive of multiple cylinder, use once sizing is put in production reality, manual operation can be substituted, enhance productivity, effectively ensure safety in production, ensure that the adjustment of posture during smooth folding and the elevator work of elevator valve.

Use the connecting rod with auto-lock function can make elevator valve after closedown, have good safety, prevent accident.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described further:

View when Fig. 1 is the unlatching of elevator valve;

View when Fig. 2 is the closedown of elevator valve;

Fig. 3, Fig. 4 and Fig. 5 are respectively three kinds of working state schematic representations of elevator;

In figure: 1-valve cylinder; 2-elevator valve; 3-connecting rod; 4-elevator cylinder.

Detailed description of the invention

Embodiment:

During workover treatment, the operating procedure of elevator is: stop elevator → open elevator valve → tubing string is pushed elevator → closedowns elevator valve → dead bolt pinning elevator valve; When winch goes downwards to certain position, buttress elevator → open dead bolt → elevator valve to flick → take out tubing string.

For this reason, valve elevator Automated condtrol mechanism of the present utility model adopts multiple cylinder to control elevator valve, the position of dead bolt and elevator, achieve the Automated condtrol of valve elevator, wherein, as depicted in figs. 1 and 2, be respectively view when elevator valve opens and closes, valve open-and-close mechanism comprises valve cylinder 1 and elevator valve 2, described valve cylinder 1 controls the folding of described elevator valve 2 by connecting rod 3, and the connecting rod 3 in this embodiment is the connecting rod with auto-lock function, can make elevator valve 2 after closedown, have good safety like this, prevent accident.

After elevator valve 2 is closed, this embodiment utilizes dead bolt to be pinned by elevator valve 2, and to ensure that elevator valve 2 can not be opened easily, dead bolt is herein by dead bolt air cylinder driven, because dead bolt just plays the effect of pinning elevator valve 2, therefore in figure and the structure at not shown dead bolt place.

In addition, no matter elevator is in trip-out or at lower brill, when elevator runs to highs and lows, all to there is the change of attitude angle in elevator, this is the needs being installed and unloading card, if do not change attitude angle, then elevator door is difficult to close or be difficult to open, for this reason, this embodiment also comprises two elevator cylinders 4, these two elevator cylinders 4 are series connection mutually, its objective is to adjust elevator different gestures operationally, as Fig. 3, shown in Fig. 4 and Fig. 5, be respectively the view that elevator three kinds is different, wherein, the elevator cylinder of series connection is between AB, the end of BO extension line is elevator, the different state of elevator three kinds can be realized by controlling these two elevator cylinders, such as, two elevator cylinders in Fig. 3 stretch out simultaneously, two elevator cylinders in Fig. 4 are retracted simultaneously, one, two elevator cylinders in Fig. 5 stretch out, a retraction.

The valve elevator Automated condtrol mechanism of this utility model is under the prerequisite not changing valve elevator performance, especially the security performance of valve elevator is not changed, its Automated condtrol is realized under the drive of multiple cylinder, use once sizing is put in production reality, manual operation can be substituted, enhance productivity, effectively ensure safety in production, ensure that the adjustment of posture during smooth folding and the elevator work of elevator valve.

The utility model is not limited to above-mentioned detailed description of the invention, and all are based on technical conceive of the present utility model, and done structural improvement, all falls among protection domain of the present utility model.
