Abstract

The utility model belongs to a general type rod elevator used for elevating sucker rods at oil field well repairing time. The general barrel type rod elevator solves the problems that an existing lifting basket type rod elevator needs detachment and replacement of a hanging hook and a hanging ring at utilization time when used independently, procedure is complex, labor is wasted, a locking ring of the lifting basket type rod elevator can not be opened when meeting impurities, thick oil and mud, bearing capacity is poor, and normal utilization can not be realized. The general barrel type rod elevator comprises a main body of a sliding elevating plate. A sliding groove is formed in the main body. A sealing cover is arranged in the sliding groove of the main body. A jacking spring is arranged between the elevating plate and the main body. A guide angle is arranged at the front end of the elevating plate. The general barrel type rod elevator can be used for elevating sucker rods different in specification, and is strong in bearing capacity.

Description

General bucket formula rod elevator

Technical field

The utility model belongs to a kind of instrument of oil pumper replacing sucker rod in the petroleum machinery technical field, and specifying is a kind of bucket formula elevator that lifts by crane various sucker rods.

Background technology

When lifting by crane sucker rod during existing oil well, when used basket type elevator uses, need to change suspension hook and suspension ring, complex procedures is required great effort again, does not open when its block ring meets foreign material viscous crude silt, and supporting capacity is poor, the problem that frequent generation can not normally be used.

Summary of the invention

Lifting used general bucket formula rod elevator during sucker rod when the utility model purpose designs a kind of oil well, the problem that exists to solve existing elevator.

General bucket formula rod elevator, it has the well-bucket body, well-bucket body one end has the well-bucket cap, an other end has well-bucket body bottom, be equipped with on the well-bucket cap for the eyenut that connects lifting appliance, well-bucket body bottom is the split ring structure, and the adjustable slip hoisting board of opening is housed in the opening of well-bucket body bottom, is equipped with between the main body of described hoisting board and well-bucket body bottom for the spring ejection mechanism that adjusts slip hoisting board openings of sizes.

The utility model is adjusted the hoisting board opening owing to the well-bucket body bottom that has with the slip hoisting board by spring, can conveniently lift by crane the sucker rod of different size, and supporting capacity is strong.

The specific embodiment

Provided the specific embodiment of the general bucket of the utility model formula rod elevator such as Fig. 1-2.It has well-bucket body 10, well-bucket body 10 1 ends have the well-bucket cap, an other end has well-bucket body bottom 12, be equipped with on the well-bucket cap 9 for the eyenut 8 that connects lifting appliance, well-bucket body bottom 12 is the split ring structure, and the adjustable slip hoisting board 17 of opening is housed in the opening of well-bucket body bottom 12, between the main body of described hoisting board 17 and well-bucket body bottom 12, is equipped with for the spring ejection mechanism that adjusts slip hoisting board 17 openings of sizes.Well-bucket body 10 is identical with well-bucket body bottom 12 shapes, is as shown in Figure 2 split ring structure.The utility model has adopted slidably hoisting board, can lift by crane easily the sucker rod of many specifications, carries out fast the combination of many sucker rods.Spring ejection mechanism is positioned on the up and down both sides correspondence position of well-bucket body bottom 12 and is positioned at spring guide 18 on the well-bucket body bottom 12, and spring ejection mechanism comprises ejector spring 19, spring guide 20, leader nut 21, spring 19 is enclosed within on the spring guide 20, and leader nut 21 is screwed on the spring guide 20.

Eyenut 8 is contained on the well-bucket cap 9 and can rotates freely by thrust bearing 4 and radial ball bearing 6, and between thrust bearing 4 and the radial ball bearing 6 oil nozzle 5 is housed, and eyenut 8 fixed ends are located with nut 2 and cottor pin 1.In thrust bearing 4 outer ends the first dust cap 3 is housed, in radial ball bearing 6 outer ends the second dust cap 7 is housed.In the well-bucket main body pressure bearing and radial ball bearing are set, the relative well-bucket cap of eyenut is rotated freely, hoisting wirerope is non-warping when the lifting sucker rod.The safety collar 11 that pins for sucker rod is housed on the well-bucket body 10.Hoisting board 17 front ends are provided with guide angle.

Well-bucket body bottom 12 ends have chute body 13, are shaped with sliding tray in chute body 13, and slide mass 14 is installed in its sliding tray, and seal cover 15 is equipped with in slide mass 14 ends.Seal cover is installed in sliding tray, is prevented that foreign material viscous crude silt from entering in the sliding tray.

Use procedure: general bucket formula rod elevator is hanging on the lifting hug, and the hoisting board of elevator is aimed at the spanner position of sucker rod elevator is shifted onto the position, with safety collar sucker rod pinned and can lift.
