Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The junk overshot for oil-water well workover comprises an overshot shell 2, guide shoes 1 are arranged on the outer circumferential wall of the bottom of the overshot shell 2, an installation seat 3 is fixed on the outer circumferential wall of the top end of the overshot shell 2 through threads, an upper connecting column 4 is fixed on the inner wall of the top of the installation seat 3 through threads, a connecting seat 5 is fixed on the outer wall of the top end of the upper connecting column 4 through threads, a spring 7 is welded on the outer wall of the bottom of the connecting seat 5, a slip seat 6 is inserted into the spring 7, the slip seat 6 is in a telescopic stepped cylinder structure, a stabilizing seat 8 is welded on the outer wall of the bottom of the slip seat 6, a slip 11 is clamped on the outer wall of the bottom of the stabilizing seat 8, the slip 11 comprises two clamping half rings, rubber suckers 12 distributed at equal intervals are arranged on the inner wall of each clamping half ring, and the rubber suckers 12 are made of polyurethane; when putting the integrated device into the oil-water well, make the fish top get into in the casing of the fishing barrel 2 through guide shoe 1, and press down, make two centre gripping semi-rings of slips 11 part, simultaneously, slip seat 6 shrink makes spring 7 shrink deformation, at this moment, loosen casing of the fishing barrel 2, spring 7 restores to the original state under the effect of deformation, and stretch slip seat 6, tensile slip seat 6 extrudees downwards, make two centre gripping semi-rings of slips 11 close tightly, and carry out the centre gripping to the top of fish, and at the in-process of two centre gripping semi-rings centre gripping, its inboard rubber suction cup 12 adsorbs the centre gripping under the effect of closing tight two centre gripping semi-rings, thereby improved the clamping-force on the fish top, also avoided the fish top to glue the problem that oily material and can't the centre gripping simultaneously, the practicality has been improved.
In order to conveniently look for and observe the fish in the pit, as shown in fig. 2, the outer wall of the bottom of the stabilizing seat 8 is provided with a mounting groove, the inner wall of the bottom of the mounting groove is fixedly provided with three cameras 10 through threads, when the fishing barrel shell 2 is placed into an oil-water well, the fish can be effectively looked for and observed through the cameras 10, when the fishing barrel shell 2 falls, and when a certain camera 10 is damaged due to collision, the other camera 10 can be looked for and observed, so that the feasibility of the whole device is improved.
In order to avoid the slip 11 from sliding off the bottom end of the overshot shell 2, as shown in fig. 2 and 3, the outer wall of the circumference of the overshot shell 2, which is close to the upper part of the guide shoe 1, is welded with a limiting ring 9, the outer walls of two sides of the stabilizing base 8 are both provided with magnetic suction grooves 15, and one side of the top ends of two clamping half rings of the slip 11 is welded with a clamping block 13; when putting fishing barrel casing 2 into the profit well perpendicularly, can effectively guarantee slips 11's stable connection to guaranteed slips 11 validity when the centre gripping fish, and then improved the security of fish centre gripping.
In order to avoid the staggered offset of the two clamping half rings of the slip 11, as shown in fig. 3, an arc-shaped block 14 is welded on one side of one of the clamping half rings of the slip 11, an arc-shaped clamping groove is formed in the opposite side of the other clamping half ring, and the arc-shaped block 14 is matched with the arc-shaped clamping groove, so that the problem that the two clamping half rings of the slip 11 are staggered and offset to cause failure is avoided.
The working principle is as follows: when the integral device is put into an oil-water well, the top end of a fish enters the fishing barrel shell 2 through the guide shoe 1 and is pressed downwards, so that two clamping semi-rings of the slips 11 are separated, meanwhile, the slip seat 6 contracts and the spring 7 contracts and deforms, at the moment, the fishing barrel shell 2 is loosened, the spring 7 restores the original shape under the deformation effect, the slip seat 6 is stretched, the stretched slip seat 6 is extruded downwards, so that the two clamping semi-rings of the slip 11 are closed tightly, the top end of the fish is clamped, in the process of clamping the two clamping semi-rings, the rubber suction cups 12 on the inner side of the slip 11 adsorb and clamp the two sides of the top end of the fish under the effect of the two closed clamping semi-rings, when the fishing barrel shell 2 is put into the oil-water well, the fish can be effectively searched and observed through the camera 10, and when one camera 10 is damaged due to collision in the falling process of the fishing barrel shell 2, the other camera 10 of accessible is look for and is observed, simultaneously, when putting into the profit well with fishing barrel casing 2 perpendicularly, can effectively guarantee the stable connection of slips 11 to guaranteed the validity of slips 11 when the centre gripping fish, and then improved the security of fish centre gripping, and the arc draw-in groove and the arc piece 14 that two centre gripping semi-rings set up relative one side of two centre gripping semi-rings have avoided two centre gripping semi-rings of slips 11 skew and the problem that the skew became invalid.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
