Abstract
The utility model relates to a small block sheave, which can be used for delivering oil conduits in oil well operation. When the small block sheave is moved under the action of the oil conduits, the rope of the small block sheave can draw a bobbin winder wheel and a core shaft to rotate simultaneously; the spring of plane volute rolling can be wound at the time and can store energy; when the oil conduits are carried out from the small block sheave, the spring can unreel, the bobbin winder wheel can rotate, and a rope can wind on the bobbin winder wheel; the small block sheave is driven and returned to the mouth of an oil well or a frame; thereby, the utility model can mitigate worker's labour intensity, enhance work efficiency, effectively protect the male buckling of the oil conduits, and reduce attrition.
Description
The utility model is a kind of jigger that oil pipe is transported in the oil well operation that is used for.
In oil well repairing operation, from oil well, carry oil pipe or in oil well during drain line, should be placed on oil pipe delivers on the shelf or the oil well mouth on the special-purpose jigger, whenever carry an oil pipe in the use or put oil pipe workman and all will shift jigger by oil well mouth or the shelf onto, in order to transporting next root oil pipe, owing to promote jigger continually, increased working strength of workers.Therefore, in a large amount of workover treatments, seldom use jigger.So two oil pipes and together as slideway.During well workover, oil pipe slides on slideway, and the pin thread on the oil pipe is usually ground away or broken like this, has increased the cost of well workover, has caused very big waste.
At the problems referred to above, the utility model provide a kind of can automatically reset jigger, avoided the wearing and tearing of oil pipe pin thread, alleviate operator's labour intensity, the utility model has following accompanying drawing.

The utility model is achieved in that in workover treatment oil pipe is placed on jigger (2) On, under the gravity or lineoutofservice signal pull effect of oil pipe, jigger (2) is barricaded as along oil pipe (1) Slideway motion, the rope (3) on the jigger (2) is by a fixed pulley (4) pulling reel (5) rotation, the mandrel (6) fixing with reel (5) also rotates like this, putting down in the reel (9) Face volute spring (10) is rolled tightly and stored energy upper at mandrel (6). When oil pipe from jigger (2) On when moving down, plane scroll spring (10) loose winding discharges deformation energy and exports torque, coiling Wheel (5) rotation and rope (3) around top, drive simultaneously jigger (2) and move, reset to By well head or the shelf, as shown in Figure 1.
Plane scroll spring (10) outer end is fixed on reel (9) inwall, and the inner is fixed on the mandrel (6), in order to strengthen the work moment of plane scroll spring (10), can be two volute springs (10) and use together, usually only with one.
Reel (5) is plastics or iron, is fixed on the mandrel (6) with methods such as key or welding, and a fixed mount (8) is arranged below reel (9), and it play supporting role, and a bearing (7) is arranged on fixed mount (8).As shown in Figure 2.
The utility model utilizes the energy storage principle of plane scroll spring (10), has realized automatically reseting of jigger (2), has simple in structurely, easy to use, increases work efficiency, and alleviates working strength of workers, protects the oil pipe pin thread effectively, reduces and damages.
Claims (4)
1. the jigger that automatically resets is made up of oil pipe (1), jigger (2), rope (3), fixed pulley (4), reel (5), it is characterized in that on end dead block (9) inwall of plane scroll spring (10), the other end is fixed on the mandrel (6) that reel (5) are housed, and rope (3) two ends are fixed on reel (5) and the jigger (2).
2. jigger according to claim 1 is characterized in that plane scroll spring (10) one or more.
3. jigger according to claim 1 is characterized in that reel (5) is iron or plastics and is fixed on the mandrel (6).
4. jigger according to claim 1 is characterized in that mandrel (6) can upward rotate at fixed mount (8) by bearing (7).
