Embodiment 1

[0022] Such as figure 2 , 3 As shown in and 4, the spring 14 is an arc-shaped elastic piece, the spring 14 is fixed on the outer wall of the housing 2 through the spring seat 15, the protruding part of the spring 14 abuts against the arched beam 12, and the arched beam 12 can slide up and down relative to the spring 14 . Both ends of the spring 14 are pressed against the outer surface of the housing 2, and the middle part is pressed against the inner surface of the arched beam 12. The spring 14 slides on the inner surface of the arched beam 12, and always forms an outward thrust on the arched beam 12, thereby pushing the lock components on the left and right sides to the maximum opening at the upper end of the stroke to complete the return action.

Embodiment 2

[0024] Such as Figure 5 As shown, the spring 14 is an annular elastic sheet, the spring 14 is sleeved outside the housing 2 and fixed and supported between the arched beams 12 .

Embodiment 3

[0026] Such as Figure 6 As shown, the spring 14 is a coil spring, and the arched beam 12 is provided with a spring fixing portion 19 protruding to both sides. The spring 14 is fixed between the spring fixing portions 19 of the two arched beams 12 on the periphery of the housing 2. The arched beam 12 is subjected to an outward elastic force.

[0027] The overall working principle of the elevator:

[0028] When the driving device is at the contraction end position, affected by the spring components, the jaws are at the maximum opening position on both sides, and the elevator is in an open state. At this time, the sucker rod collar and the sucker rod end can go up from the guide head at the lower end of the elevator and the guide port to the bottom of the limit part (Note: the actual operation is to lower the hook of the workover rig to put the elevator in and fix it. sucker rod coupling).

[0029] The actuator stretches out to push the claw assembly down; the slope of the cl...

Abstract

The invention relates to special tools for the oil and gas industry, and provides a sucker rod automatic elevator. An upper sliding groove (5) and a lower sliding groove (6) are formed in the wall ofa housing (2), an upper inclined surface (7) and a lower inclined surface (8) are arranged on the inner wall of the housing (2), and a trumpet-shaped guiding opening (9) is formed in the lower end ofthe housing (2); an elevator claw comprises an upper claw body (10), a lower claw body (11), and an arched beam (12), the upper claw body (10) and the lower claw body (11) are provided with inclined surfaces correspondingly and are in contact fit with the upper inclined surface (7) and the lower inclined surface (8) of the housing (2) through the inclined surfaces correspondingly, and the top andbottom ends of the arched beam (12) extend through the upper sliding groove (5) and the lower sliding groove (6) to be fixedly connected with upper claw body (10) and the lower claw body (11); and theupper claw body (10) is connected with an actuator (3) of a driving device (4) through a transversely arranged pin shaft (13), and the elevator claw is provided with a spring (14) which keeps the elevator claw open outwards. The sucker rod automatic elevator has high structure strength and high safety, and does not require direct manual operation.

Description

technical field [0001] The invention relates to a special tool for the oil and gas industry, which is suitable for automatic well workover or conventional minor workover and workover, and in particular relates to a sucker rod elevator. Background technique [0002] The sucker rod elevator is an important tool for lifting and lowering the sucker rod in the workover operation. At present, the clamping of the elevators is done manually by workers, which has the disadvantages of low operating efficiency, long clamping time and low safety factor. It is an irreversible general environment and general trend that various workover operations in oilfields are developing towards automation. In actual application, in the products that the market can provide, and in the open documents that have been found, there is no sucker rod elevator product that can realize the automatic clamping function to appear. Contents of the invention [0003] The technical problem to be solved by the pre...
