Description

Stand elevator

Technical Field

The invention relates to the field of oil field well repairing equipment, in particular to a vertical elevator which is suitable for matching with a slotted traveling block and a closed type linkage turning plate elevator for operation.

Background

In the prior art, in the traditional drilling and workover operation, in the operation process of lifting a pipe column, when an oil pipe is lifted in place, a traveling block hook cannot be immediately released, and the traveling block hook can be released after the oil pipe is broken off. Put the tubular column operation process under, the trip car hook just can empty the hook and transfer after need waiting to buckle on the tubular column, has excessive latency among the whole operation process, and the operating efficiency is low. Meanwhile, the single pipe column lifted and lowered is moved by well mouth operators, and the physical consumption is high.

Disclosure of Invention

The invention aims to overcome the defects and provides a vertical root elevator tool which is matched with a slotted traveling block and a closed type linkage turning plate elevator for use, so that the labor intensity is reduced, and the working efficiency is improved.

The technical solution of the invention is as follows: the elevator for the root stand is characterized by comprising a sleeve-shaped elevator body with an opening at one side, a valve which is pushed and pulled around the sleeve-shaped elevator body is arranged at the opening of the sleeve-shaped elevator body, the lower end of a lifting rod is connected with the upper end of the sleeve-shaped elevator body in a fork-shaped manner, and the lower end of the lifting rod is in a bow shape.

In the above-mentioned scheme, the first step of the method,

the telescopic elevator is characterized in that the upper end of the telescopic elevator body is provided with two lifting lugs opposite at intervals, the lower end of the telescopic elevator body is provided with a bottom plate, a through hole is formed in the middle of the bottom plate, an end guide plate is vertically arranged on one side of the opening of the telescopic elevator body, insertion holes are formed in the upper portion and the lower portion of the end guide plate at intervals, a tension spring fixing lug plate is arranged at a position close to the end guide plate, and a fixing handle is arranged on the outer surface of the telescopic elevator.

The valve be a fork form arc door of one end area handle and insert, fork form arc door inserts the rear portion and has the fixed otic placode of extension spring.

By adopting the product, in the process of lifting a pipe column, after the pipe column is lifted in place and a next pipe column is clamped by a wellhead pneumatic slip, an operator manually opens the pipe column elevator valve, puts the pipe column into the elevator, automatically closes the pipe column elevator valve after loosening, clamps the pipe column coupling on the bottom plate of the elevator body when the pipe column elevator is lifted, and the diameter of the pipe column coupling is larger than the opening size of the elevator body, so that the pipe column cannot automatically slide out, the unloaded pipe column can be safely and reliably moved to a two-layer platform pipe arranging position, and the labor intensity of the operator is greatly reduced; meanwhile, the slotted traveling block is lowered, and the rest pipe column is continuously lifted, so that the operation time can be greatly reduced. In the process of lowering the pipe column, when the open-slot type traveling block and the closed type linkage turning plate elevator lower a pipe column and then lift the pipe column by an empty hook, the single pipe column at the position of the racking platform can be moved to a well mouth position in advance by the vertical elevator, the pipe column is buckled on the pipe column, the open-slot type traveling block can directly drive the pipe column to lower the pipe column after reaching the top of the pipe column, waiting is not needed, and the operation time is greatly shortened and the labor intensity is reduced.

The invention is adopted to carry out the matched operation process, the time of the moving block descending in no-load is coincident with the time of the pipe column tripping and the time of the pipe column moving to the racking position, and the time of the moving block ascending in no-load is coincident with the time of the pipe column moving to the well mouth and the pipe column moving to the well mouth, thereby saving the time of the moving block hovering waiting when the pipe column is tripped up, tripped and moved, and improving the operation efficiency by about 50 percent. Meanwhile, the pipe column is moved back and forth at the well mouth and the racking pipe by adopting the invention, so that the labor intensity of operators can be effectively reduced.

The invention has the advantages that: 1. the elevator body is designed to be heavier, and the elevator body is inclined in a free state, so that the tubular column can conveniently enter the elevator body. 2. The structure of manual opening and automatic closing of the valve is simple and convenient to operate, the operation time of operators is reduced, and the labor efficiency is improved. 3. The lifting rod door type and the offset structure provide sufficient space for the tubular column to enter the elevator body, and can effectively avoid the interference of the tubular column and the lifting rod. 4. The whole stand elevator is light in structure and low in labor intensity of wellhead operators.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
