Abstract
The utility model discloses a well repairing tool, i.e. a multipurpose oil pipe clamping device for repairing a well. The multipurpose oil pipe clamping device for repairing a well tightly clamps an oil pipe in the oil pipe disassembling operation. The multipurpose oil pipe clamping device for repairing a well is provided with a main body, wherein, the middle part of the main body is provided with a conical hole. Three opening clamping tiles which are mutually hinged are positioned in the conical hole, and the opening clamping tiles are hinged with an operating handle device which is fixed on the main body. The side edge of one section of the conical hole on the main body is communicated with outside world, and is closed by a sliding door. The multipurpose oil pipe clamping device for repairing a well has the characteristics that when the oil pipe is disassembled, the oil pipe can be convenient to clamp, oil stain on the surface of the oil pipe can be scraped off, the operation labor intensity of workers is alleviated, and the pollution of a well field is reduced.
Description
The utility model relates to a kind of oil field shaft mouth workover tool, and promptly well workover multipurpose oil pipe clamp tightly installs.
When removing the oil pipe operation in the oil field, need the hand-held respectively oil pipe tongs of two workmans to block oil pipe up and down on the contrary, finish dismounting, its shortcoming is that the card pipe needs two workmans to operate simultaneously, labor strength is big, production efficiency is low, once the fracture of swing pipe hook takes place, oil pipe falls wayward, poor safety performance.The oil pipe surface is stained with a large amount of greasy dirts in addition, influences operating environment.
By removing the sticking greasy dirt in oil pipe surface, below the bulk oil pore, stud with rubber ring, oil pipe by the time can scrape off surface and oil contaminant.
The utility model purpose is to provide a kind of card pipe unit that can block oil pipe safely and reliably that is fixed in well head at above-mentioned deficiency, and another purpose provides a kind of well workover multipurpose oil pipe clamp that can conveniently scrape off the oil pipe surface and oil contaminant and tightly installs
The utility model is achieved in that the tight device of well workover multipurpose oil pipe clamp comprises the main body of a middle part band taper hole, and there is the flange hole on four limits, can be fixed on the well head.Be located in three opening slips that are hinged along taper hole, slips is hinged with the control crank device that is fixed on the main body, and last handle can make slips move up and down along taper hole, and the centre bore that slips is formed becomes and diminishes greatly.The slips opening advances oil pipe from the side.One section side of taper hole communicates with the external world on the main body, and by the sliding door sealing, pushes the back from the side and go up sliding door to guarantee oil pipe.
The utility model has the advantages that: 1, safe and reliable.The gripping mechanism of well head is fixed in employing, and oil pipe is positioned.Band tapering slips in the middle of adopting, card is tight more more under the deadweight effect to make oil pipe, has avoided the oil pipe well accident that falls, and is safe and reliable.2, adopt this device after, can reduce operating personnel one people, alleviated labor strength.3, this gripping mechanism has rubber ring, oil pipe by the time can scrape off oil-pipe external wall greasy dirt more than 98%, both improved the well head operating environment, alleviated the well site pollution again.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing is the utility model structure diagram.
Referring to accompanying drawing, the tight device of well workover multipurpose oil pipe clamp is by the main body 1 in flanged hole, and its middle part has taper hole, three hinged slips 2 are uniform along taper hole, and claw 3 is arranged on the slips 2, and claw is plugged on 2 of the slips, according to different calibers, the different claw 3 of corresponding replacing, claw 3 wearing and tearing backs are replaceable.Main body 1 right side has fuel feed pump to push the interior gap of taper hole, and gap is by sliding door 4 lockings.Slips 2 is connected by hinge 6 with stick control device 5 on being fixed on main body 1.Rubber ring 7 is installed in main body taper hole lower curtate.During use, the frizing rubber ring 7 that will conform to the oil pipe specification is inserted in by on the card oil pipe, press down handle 5, make on the slips 2 and carry, it is big that its centre bore becomes, oil pipe is pushed taper hole from the main body right side and makes rubber ring 7 place main body 1 bottom, this device is fixed on the well head, and under oil pipe deadweight effect, slips is embraced oil pipe, embrace tighter and tighter, at this moment an operative employee can twist oil pipe top connection or parts.When pipe pine presses down handle 5, make to carry on the slips 2 and unclamp oil pipe, under the drop hanger effect can on carry oil pipe, on move past and scrape off its surface and oil contaminant in the journey.Control crank 5 is tightened oil pipe at an arbitrary position, unclamps.
