Abstract
The utility model relates to a hydraulic controlled locking device for maintaining standing derrick in the process of oilfield workover job, which is composed of a crank arm (3), a bracket (4), a hydraulic cylinder (5), a reinforcing plate (6), a supporting seat (8) and pin shafts (1), (2), (7). The hydraulic controlled locking device can ensure the exact reverse drawing and pushing actions in the process of maintaining standing derrick and favorably and safely complete the working of standing the derrick. The utility model has the advantages of simple structure, convenient operation, and flexible and reliable action, and the hydraulic controlled locking device is suitable for popularizing and applying in the mine workover job.
Description
The utility model relates to a kind of hydraulic control locking device that oil well repairing operation process derrick stands up work that is used for.
In the oil well repairing operation process, the 18m workover derrick is whole unlucky to the well site of constructing by back of the body derrick car, hoists and takes off bridge and lift derrick and send into specified angle by being contained in raising cylinder on the main car then.At this moment, the safety locking motion that is installed on the gin pole top of the trellis goat's horn plate begins to work, and guarantees when derrick gives rise to certain angle not out of control.At present, oil well repairing operation 18m derrick stands up in the process these cover safeties and all adopts the pneumatic direct selling device of direct contact.Because pneumatic direct selling directly contacts with the derrick girder, easily make piston sell generation flexural deformation and surperficial scratch directly to households after frequent the use, cause the direct selling can not self-return.And, easily freezing in the pneumatic control system when use winter, pneumatic element is malfunctioning, thereby causes safeties out of control, causes that derrick is out of control topples over, or derrick self damages, or smashes other equipment of derrick, even jeopardizes personal safety, causes the great number economic loss.
Task of the present utility model is to provide a kind of workover treatment derrick to stand up the hydraulic control locking device, and this kind hydraulic control locking device can make derrick stand up to pull back in the process that to push action accurate, and it is not out of control to guarantee that the 18m derrick stands up smoothly.
The utility model is to realize like this.It by bearing pin (1), (2), (7) crank arm (3), support (4), fluid cylinder (5), strong plate (6) and bearing (8) form, its package assembly feature is as follows: crank arm (3) are hinge type with fluid cylinder (5) upper end with support (4) respectively by bearing pin (1), (2) and are connected, fluid cylinder (5) lower end is hinge type by bearing pin (7) with bearing (8) and is connected, and support (4) and bearing (8) are welded on the upper and lower part of strong plate (6) respectively.Will be integrally welded by strong plate (6) in the above-mentioned hydraulic control locking device that assembles and the left and right sides goat's horn plate that is installed on main pickpocket on a bus or train's bridge, corresponding manipulator about then forming.The operating principle of this device is as follows: fluid cylinder (5) links to each other with main car hydraulic power source and control valve through hydraulic fluid pipeline, flow to out fluid cylinder (5) by control valve control liquid, liquid cylinder piston is moved back and forth, bearing pin (1) promptly drives crank arm (3) and swings around bearing pin (2), realizing that it tightens up derrick to pull back, open pushes finishing of action, stands up derrick safely and reliably.
The utlity model has simple in structure, flexible movements are reliable, characteristics such as easy to operate, utilize this device can stand up derrick smoothly, safely and reliably when workover treatment.
Accompanying drawing is a general structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
In the utility model, crank arm (3) be the rectangular square body that middle part folding turns, its horizontal segment end face is a rectangle, the section of upwarping end band semi circular surface, middle part folding flex point and the section of upwarping end are respectively equipped with in order to the circular hole of bearing pin (2), (1) to be installed.Support (4) is a triangle steel plate, and its upper right arm of angle portion is semi circular surface, and is provided with one in order to the circular hole of bearing pin (2) to be installed.Fluid cylinder (5) is by circle tube cylinder and place the cylindrical piston that also can move back and forth in it to constitute, and upper and lower end is respectively equipped with in order to penetrate the circular hole of bearing pin (1), (7), also has 2 feed liquor eyelets on the cylinder body.Strong plate (6) is that a cross section is trapezoidal rectangular steel plates.Bearing (8) one side end faces are rectangle, opposite side band semi circular surface, and be provided with one in order to the circular hole of bearing pin (7) to be installed.
Claims (4)
