Abstract
The utility model discloses an elastic rope retainer which is composed of an upper joint, a plate spring and a fishing rod, wherein the upper joint and the fishing rod are connected through threads; the fishing rod is a hollow tubular body; the middle outer tube wall of the fishing rod is provided with an outer shoulder, of which the outer diameter is smaller than the internal diameter of the lower part of the upper joint; the outer shoulder of the fishing rod is provided with a clamping groove; and the plate spring is clamped and connected in the clamping groove. When the downhole rope needs to be fished, the upper joint is connected with a downhole tube, and the fishing rod is connected with a fishing spear hook; in the lowering process of the downhole tube, the plate spring goes down along the sleeve wall and scrapes and extrudes ropes and the like attached to the inner wall of the sleeve, thereby effectively preventing the downhole ropes and the like from running onto the fishing tool, causing stuck accidents; and even if part of impurities are positioned on the fishing tool, when lifting the tube, the plate spring is compressed, thereby effectively avoiding the stuck accidents.
Description
Technical field
The utility model relates to a kind of elasticity retaining rope device, belongs to the rope salvaging technical field of tools of using in the drilling wells such as oil, geology, the hydrology, colliery, and fishing tool is used in the down-hole accident processing that is particularly useful in the petroleum drilling engineering.
Background technology
At present, the fishing tool kind is a lot of both at home and abroad, but the object that prevents rope and so on all crowfoots is gone to the method on the fishing tool, all adopts the baffle plate of rigidity.ZL97210336.8 discloses a kind of anti-sticking hawser and has dragged for lance, comprises the lance bar, crowfoot, salvaging dish and anti-block cheese, and anti-block cheese also is a rigidity, when in the pit shaft of reducing, salvaging process, is prone to cause the generation of lock of tool drilling.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned prior art, and the fishing tool that in the salvaging process, exists is prone to the defective of bit freezing, and a kind of fishing tool elasticity retaining rope device is provided.
A kind of elasticity retaining rope device; Be made up of top connection, leaf spring, fishing rod, top connection is threaded with fishing rod, and fishing rod is a hollow tubular body; The middle part outer tube wall of fishing rod is provided with outer shoulder; Its external diameter is less than the internal diameter of top connection bottom, has draw-in groove at the outer shoulder of fishing rod, is connected with leaf spring in the draw-in groove.
The outer shoulder in fishing rod middle part is the taper shoulder, is evenly equipped with 3 or 4 draw-in grooves on the outer shoulder.
Leaf spring is an arcuate structure, and its external diameter is greater than the external diameter of top connection, and wall is provided with the corresponding key of draw-in groove that is uniformly distributed with on the outer shoulder with fishing rod within it.
The beneficial effect of the utility model is to combine with fishing tool, when the fishing tool put-on and delegated, can stop effectively that the object of rope and so on is gone on the fishing tool, avoids the generation of lock of tool drilling.
Description of drawings
Fig. 1 is the utility model sectional drawing;
Among the figure: 1-main body, 2-leaf spring, 3-fishing rod.
The specific embodiment
As shown in Figure 1; The utility model is made up of top connection 1, leaf spring 2, fishing rod 3, and top connection 1 is threaded with fishing rod 3, and fishing rod 3 is a hollow tubular body; The center outer tube wall is provided with outer shoulder; Its external diameter is less than the internal diameter of top connection 1 bottom, has draw-in groove at the outer shoulder of fishing rod 3, is connected with leaf spring 2 in the draw-in groove.
Shoulder is the taper shoulder outside described fishing rod 3 middle parts.
Be evenly equipped with 3 or 4 draw-in grooves on the outer shoulder of described fishing rod 3.
Described leaf spring 2 is an arcuate structure, and its external diameter is greater than the external diameter of top connection 1, and inwall is provided with the corresponding key of draw-in groove that is uniformly distributed with on the outer shoulder with fishing rod 3.
When needs are salvaged the down-hole rope; The top connection 1 of the utility model is connected with running string; Fishing rod 3 is connected with the fishing spear hook, transfers in the process at tubing string, and leaf spring 2 is descending and scrape the object that squeezes attached to rope on the internal surface of sleeve pipe and so on along casing wall; Can effectively avoid the object of down-hole rope and so on to go on the fishing tool, cause the generation of lock of tool drilling; If there is partial impurities to be positioned on the fishing tool, when the upper lifting pipe post,, can be compressed because leaf spring 2 is flexible, effectively avoid the generation of lock of tool drilling.
