Abstract

The utility model relates to an elevator for rod job in workover rig service to oil well in oil fields, namely an anti-dropping bail elevator for a sucker rod, which comprise a bail, an elevator body connected with the bail and a safety loop sleeved on the elevator body, wherein a locking pin is arranged on the safety loop; the locking pin is composed of a locking pin rod, a spring sleeved on the locking pin rod and a spring seat disposed outside the spring; the spring seat is connected with the safety loop through outside welding; and correspondingly, the elevator body is provided with a locking pin rod jack. The safety loop is fixed all the time in production, accordingly the sucker rod is prevented from dropping. When in use, the safety loop and the elevator body are mutually connected in locking mode without shifting, and block a lateral cavity for the sucker rod to pass through all the time, accordingly the anti-dropping bail elevator for the sucker rod effectively prevents the sucker rod from dropping, and has the advantages of being safe to use, reasonable in structure, and convenient to operate.

Description

The separation preventing sucker rod is carried and is drawn ring

Technical field

The utility model relate to a kind of be applicable in the oilfield workover rig service to oil well rise, the elevator of lower sucker rod, promptly the separation preventing sucker rod is carried and is drawn ring.

Background technology

In the prior art, sucker rod carries that to draw ring (rod elevator) be the oil and gas industry standardized product, standard No. SY/T5235-2008.The elevator body that it comprises drop handle, be connected with drop handle and be enclosed within safety loop (or claiming lock ring) on the elevator body is connected on sucker rod hook or the hook block, is used to block sucker rod.During concrete the use, scurrying on the safety loop, sucker rod inserts on the elevator body by intake on the elevator body, put down safety loop again and block intake, prevent that sucker rod from coming off, its shortcoming is in the actual use, because various factors, can cause scurrying on the safety loop, make sucker rod come off, influence is produced and is dangerous.

The utility model content

The purpose of this utility model is to provide the better separation preventing sucker rod of a kind of result of use to carry at above-mentioned deficiency to draw ring.

Technical solution of the present utility model is: the separation preventing sucker rod carry draw that ring comprises drop handle, the elevator body that is connected with drop handle and be enclosed within safety loop on the elevator body.Lock pin or pinning are arranged on the safety loop, and safety loop is fixed all the time aborning, has prevented that effectively sucker rod from coming off.Preferred detent configuration.

The utility model has the advantages that: 1, safety loop and elevator body locking in use is connected, can play, block the side chamber that the confession sucker rod passes through all the time, and prevented that effectively sucker rod from coming off, use safer.2, rational in infrastructure, easy to operate.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

The specific embodiment

Referring to Fig. 1, the separation preventing sucker rod is carried and is drawn ring and comprise drop handle 1, the elevator body 2 that is connected with drop handle 1 and be enclosed within safety loop 3 on the elevator body 2 (or title lock ring cover) on the safety loop 3 lock pin is arranged.This lock pin by lock pin bar 4, thereafter control handle 12, be enclosed within spring 5 on the lock pin bar 4, spring 5 outer spring bases 6 are formed, spring base 6 and safety loop 3 external weldings have lock pin bar jack 7 on the corresponding elevator body 2.Elevator body 2 surface is along the chute 8 that has lock pin bar 4 to insert up and down, and this structure is that slidingtype separation preventing sucker rod is carried and drawn ring.Operation: drop handle 1 assembly is hung on the sucker rod hook, pin.Safety loop 3 is contained on the elevator body 2, drives with the lock pin bar 4 that passes, and slides up and down.Stir control handle 12, pull out lock pin bar 4, carry control handle 12 in the slip, it is up along chute 8 that lock pin bar 4 drives safety loop 3, open sucker rod intake 10, sucker rod is introduced elevator body 2 settle down, drop-down control handle 12, safety loop 3 is resetted, unclamp control handle 12, lock pin bar 4 enters elevator body 2 lock pin bar jacks 7 under spring 5 effects, pin safety loop 3 and seal intake 10, can rise, lower sucker rod.In lifting sucker rod process, safety loop 3 can play under the lock pin effect, seals sucker rod intake 10 all the time, guarantees that sucker rod can not come off in the lifting process, and is safe in utilization.

Referring to Fig. 2,3, the safety loop 3 outer positioning sleeves 9 that are surrounded by, positioning sleeve 9 is fixedlyed connected with elevator body 2, the intake of putting into for sucker rod 10 is arranged on positioning sleeve 9 surfaces, there is the targeting port 11 (120 degree radiation angle) that rotates along circumference for lock pin bar 4 on positioning sleeve 9 surfaces, and this structure is that rotary type separation preventing sucker rod is carried and drawn ring.Rotate control handle 12 along targeting port on the positioning sleeve 9 11, drive lock pin bar 4 and stir safety loop 3 rotations, open sucker rod intake 10, sucker rod is introduced elevator body 2, settle down, revolution control handle 12, guiding safety loop 3 resets, 4 lockings of lock pin bar, safety loop 3 is sealed intake 10, pins sucker rod.On drop handle 1, realize, lower sucker rod.After fulfiling assignment, repeat above action, discharge sucker rod, finish one-stop operation.
