Abstract

The utility model relates to a novel drill pipe elevator for the workover treatment of an oil field, which consists of an elevator body, a baffle ring, a pin roll, a valve, a handle, a pressure ring, a bushing, a locking pin, a door spindle and stop pins, wherein the baffle ring milled to be an annular groove is arranged in the elevator body; the valve is arranged in the middle of the elevator body; the pin roll is arranged between the elevator body and the valve; the handle is in screwed connection with the valve; the pressure spring is pressed and arranged in the bushing; the door spindle is fixed and pressed on the pressure spring by the locking pin; and the stop pins are inserted into the stop pin holes preserved at two ends of the elevator body, so that the baffle ring is closed. According to the drill pipe elevator, the problems in the prior art that the handle and the pin roll of the traditional elevator are frequently worn, the elevator is often broken and a novel elevator is required to be repurchased so as to increase the cost are solved. The drill pipe elevator can be widely applied to the workover treatment of the oil field, can be used for a long term and is required to replace the spring without replacing the handle and the locking pin.

Description

A kind of novel drill pipe elevator

Technical field

The utility model relates to a kind of novel drill pipe elevator that oil well repairing operation is used.

Background technology

At present, the drill pipe elevator that use in workover treatment in domestic oil field, lock drilling rod by handle and lock pin mode, the wearing and tearing of handle and lock pin frequently appear in work progress, often rupture, because manufacturer's handle and lock pin specifications and models disunity cause the drill pipe elevator accessory to be difficult to install and can't use, then need to purchase again new elevator, increase workover cost.

The utility model content

The purpose of this utility model provides a kind of novel drill pipe elevator, this elevator solved exist in the prior art the wearing and tearing of handle and lock pin frequently appear in the well workover process, the problem of fracture often takes place, do not need often to change handle and lock pin.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel drill pipe elevator, form by card body, baffle ring, bearing pin, valve, handle, stage clip, lining, lock pin, door-hinge, backing pin: in the card body, mill the baffle ring of groove circlewise, and in the middle of the card body, be provided with valve, between card body and valve, be provided with bearing pin, with the handle screwed connection on valve, stage clip is fitted in the lining, door-hinge is fixed and is pressed on the stage clip with lock pin, backing pin is inserted in the backing pin hole of reserving at card body two ends, make the baffle ring sealing.During work: elevator is opened: hold on the handle and carry, move on the handle valve bearing pin, bearing pin is extracted obturator hernia out.At this moment outer drawing, the valve rotation, elevator is opened.

The elevator locking: hold handle to the rotation of locking direction, the contact of relative inclined-plane with the card body of the inclined-plane of bearing pin upper and lower side produces component upwards, and handle valve bearing pin moves simultaneously, is rotated in place.Under the effect of spring and gravity, valve, bearing pin move down, and bearing pin inserts the obturator hernia locking.Body weight is pressed on card body and the valve, valve can not on move, elevator is when bearing a heavy burden, valve can not be opened.

The beneficial effects of the utility model are, this elevator handle, lock pin are not easy to wear, and elevator can use for a long time, only needs to change spring, need not change handle and lock pin, is convenient to change operation.

Description of drawings

Fig. 1 is the utility model overall structure schematic diagram.

1 by card body, 2 baffle rings, 3 bearing pins, 4 valve, 5 handles, 6 stage clips, 7 linings, 8 lock pins, 9 door-hinges, 10 backing pins among the figure.

The specific embodiment

At Fig. 1, in, a kind of novel drill pipe elevator is by milling the groove and the shelves ring 2 of packing into circlewise in the card body 1, and in card body 1, be provided with valve 4, be provided with bearing pin 3 between card body 1 and valve 4, on valve 5, stage clip 6 is fitted in the lining 7 with handle 5 screwed connections, door-hinge 9 usefulness lock pins 8 are fixed and are pressed on the stage clip 6, will, backing pin 10 inserts in the backing pin hole of reserving at card body 1 two ends, makes baffle ring 2 sealings.
