Abstract
The utility model discloses a top sheave for splitting a logging cable in the oil industry, wherein the top sheave for splitting the logging cable can prevent the logging cable from jumping out from the top sheave and a lower sheave and prevent the lower sheave from being blocked and turned over during the process of splitting cables. The top sheave for splitting the logging cable comprises a top sheave support, wherein cable fixed wings are arranged on the two sides of the top sheave support, and the logging cable in the top sheave is guaranteed not to jump out. The lower sheave which is matched with the top sheave comprises a lower sheave support, wherein a wellhead connector is arranged on the lower end of the lower sheave support, and a jumping preventer is arranged in an empty slot of the lower sheave support. The wellhead connector is connected with a wellhead flange to fix the lower sheave, and the lower sheave is guaranteed not to turn over. The jumping preventer guarantees the logging cable in the lower sheave not to jump out. The top sheave for splitting the logging cable is safe and reliable, is greatly convenient to split the logging cable, is simple to operate, and is convenient to maintain. The top sheave for splitting the logging cable can effectively prevent the top sheave and the lower sheave from being blocked and clamped to cause the cables to jump out and to be blocked, and improves efficiency of construction.
Description
The application is 201120339965.5 divides an application.The title of original application: a kind of top sheave and ground pulley that removes logging cable; Application number: 201120339965.5; The applying date: on August 29th, 2011.
Technical field
The utility model relates to the device that petroleum industry removes logging cable, and particularly a kind of top sheave that removes logging cable can prevent that logging cable from job-hoping and prevent the ground pulley overturning that in removing the process of cable, is hampered from top sheave and ground pulley.
Background technique
Logging cable is through being fixed on the top sheave on the travelling block and being fixed in the ground pulley lower going-into-well of well head in the process of removing.If be hampered, meet card, cable is jumped out from the groove of top sheave and ground pulley.In its using process,, be simple on the top sheave with anti-jump on the clamping plate of pulley bracket anti-jump problem that solves cable in order to prevent this job-hopping phenomenon.The field proves, to jumping significantly at being hampered suddenly, the meeting cable that card causes that removes fast in the process, this method can not prevent the cable job-hopping effectively.In the use of ground pulley, just simply be fixedly connected ground pulley with well head with wire rope, in case remove the card that is hampered in the process, ground pulley can overturning, causes cable to take off groove fully, makes cable impaired even scrap easily.When cable slack, also need manual work to set upright ground pulley in addition.There is serious potential safety hazard in the use of top sheave and ground pulley.
Summary of the invention
The purpose of the utility model provides a kind of top sheave that removes logging cable, can solve the logging cable job-hopping effectively, the problem of ground pulley overturning.Eliminate safe hidden trouble, ensure the safety of workmen and logging cable.
The technical solution of the utility model is:
A kind of top sheave that removes logging cable comprises the top sheave support, in the both sides of top sheave support the cable fixed-wing is installed, and guarantees that the logging cable in the top sheave is not job-hoped.
Compared with prior art the utlity model has following useful effect: the utility model is safe and reliable, in the both sides of top sheave support the cable fixed-wing is installed, and greatly facilitates removing of logging cable, and is simple to operate, easy to maintenance.Can prevent effectively that top sheave is hampered, meets the phenomenon that card causes cable job-hopping, card cable in work progress.Use wellhead connector that ground pulley directly is connected on the wellhead flange dish, fixation, reliable operation ensured the safety of constructing operation workman and logging cable effectively, solved the phenomenon that ground pulley overturning, cable go out groove.Improve efficiency of construction, reduced the wearing and tearing of cable and top sheave, reduced cost of production.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
A kind of top sheave that removes logging cable comprises top sheave support 5, in the both sides of top sheave support 5 the cable fixed-wing is installed.The cable fixed-wing comprises movable pulley 1 and anti-jump support 2, and an end of anti-jump support 2 is installed movable pulley 1, and the other end is provided with fixed handle 3.Anti-jump support 2 is curved supports, and its radian conforms to the radian of top sheave; Said fixed handle 3 is provided with bolt hole and retaining ring 4, and retaining ring 4 is welded on the side top of fixed handle 3.
A kind of ground pulley that removes logging cable that is used with top sheave comprises ground pulley support 6, and the mounting shaft opening connector in the lower end of ground pulley support 6 is installed anti-jumping-off device in the dead slot of ground pulley support 6.Wellhead connector comprises connection support 8 and lock(ing) bolt 7, connects support 8 and is provided with fixed claw, and lock(ing) bolt 7 is contained in the fixed claw that connects support 8.The pawl end of fixed claw is provided with the lock(ing) bolt hole, and the other end of last fixed claw is provided with fixed bolt hole and is connected with the lower end of ground pulley support 6.Anti-jumping-off device comprises fixed plate, return spring 9, movable pulley 10 and anti-jump support 11; End at anti-jump support 11 is installed movable pulley 10; The other end is connected with fixed plate through rotating shaft, fixing return spring 9 between fixed plate and anti-jump support 11, and fixed plate is installed in the dead slot of ground pulley support 6; This dead slot is meant original dead slot on the ground pulley support 6, referring to the dead slot on the top sheave support 5 among Fig. 1.
At first open the clamping plate of top sheave support 5 one sides, the cable fixed-wing of top sheave is inserted on the holding down bolt of top sheave through retaining ring 4, tighten nut after resetting.The ground pulley wellhead connector inserts in the clamping plate of ground pulley support 6, passes fixed bolt hole with bearing pin and connects, and the ground pulley anti-jumping-off device is connected with fixed plate with rotating shaft, is installed in movable pulley 10 end of anti-jump support 11 again.Put into the dead slot of ground pulley support 6 clamping plate to the fixed plate that connects, fix, load onto return spring 9 with bolt.Behind the top sheave rigging out, the connection support 8 of ground pulley wellhead connector is aimed at the idle bolt hole of wellhead flange, link together wellhead flange with the fixed claw that is connected support 8, guarantee the effectively fixing of ground pulley with lock(ing) bolt 7.Draw back the movable pulley 10 of ground pulley, unclamp after cable is passed ground pulley, the movable pulley 10 of ground pulley is under the effect of return spring 9, and self-return is in the ground pulley groove.Open the cable fixed-wing of top sheave both sides, cable is passed top sheave, the fixed-wing with both sides puts down again.The movable pulley 1 of top sheave is imported in the groove of top sheave, the cable fixed-wing of both sides is fixed, can normally remove logging cable with bolt.
