Detailed description of the invention
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. determines according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this diameter adjustable spiral wire fish fisher comprises top connection 1, fishing socket, spring assembly and briar tooth 3; Be installed with in the lower end of top connection 1 in up-narrow and down-wide fishing socket, fishing socket comprises the narrow footpath cylinder section on top, the wide footpath cylinder section of bottom and the narrow footpath section reducing cylinder section to wide path angled transition; On fishing socket, circle distribution has the axial gap run through up and down, and fishing socket is separated into the elasticity bailer grab 2 of at least two arcs by axial gap; Between elasticity bailer grab 2, radial direction is installed with spring assembly; Elasticity bailer grab 2 inner face of wide footpath cylinder section is fixed with the briar tooth 3 that spiral wire can be tangled respectively.When salvaging spiral wire fish, first the utility model is connected with the cable rope being used for salvaging by top connection 1; Cable rope by the utility model along borehole wall G.I.H, judged the Position on the top of the fish of spiral wire fish by cable stretch after, above carry, then transfer at a high speed, fishing socket is enclosed within spiral wire fish by the impact force accelerating to be formed by gravity, and is arrested by spiral wire fish by briar tooth 3; In the process, spring assembly can make the bottom radial direction of elasticity bailer grab 2 open or shrink; Fishing socket is under the effect of high speed impact power, and the elasticity bailer grab 2 of wide footpath cylinder section outwards can open and be enclosed within spiral wire fish vertically downward, and briar tooth 3 is inserted in spiral wire fish gap location and is arrested; When carrying on salvaging, elasticity bailer grab 2 by radial contraction by the narrower tubing string section in down-hole, can be carried smoothly; Effectively prevent from occurring jam in well, reduce and salvage difficulty; The reducing cylinder section of fishing socket plays the effect of guiding transition.
according to actual needs, above-mentioned diameter adjustable spiral wire fish fisher can be made further optimization and/or improvements:
as shown in accompanying drawing 1,2, resilience assembly comprises ring spring 4 and spring arch clasp 5; Ring spring 4 is the turn of the annular that spring head and the tail are connected to form; Be installed with spring arch clasp 5 respectively in the inner of elasticity bailer grab 2, ring spring 4 to be fixed on along the inner arc surface horizontal circle of elasticity bailer grab 2 on the upside of the elasticity bailer grab 2 of wide footpath cylinder section by spring arch clasp 5; Ring spring 4 is positioned at the top of briar tooth 3 topmost.
as shown in Figure 1, elasticity bailer grab 2 is tip pawl, is provided with slotting pawl tip 6 in the bottom of elasticity bailer grab 2; Insert the bottom of pawl tip 6 formed respectively by chamfering in obliquely fall angled end-face 7; Insert limit, pawl tip about 6 two ends and form the tip limit of falling splay end 8 respectively by inner bevel, the limit, two ends, left and right of elasticity bailer grab 2 is formed respectively by inner bevel drags for the pawl limit of falling splay end 9.In shaft bottom, between spiral wire fish and pipe string internal wall, there is salvaging gap; Elasticity bailer grab 2 captures spiral wire fish by inserting to salvage in gap; Insert pawl tip 6 and play the effect facilitating elasticity bailer grab 2 to insert downwards; In addition, due to the scrambling of spiral wire fish, the width salvaging gap is different, for preventing occurring, between elasticity bailer grab 2 side end edge and spiral wire fish, jam occurs in the process inserted, have also been made at the dual-side of elasticity bailer grab 2 and tiltedly process, improve the efficiency and reliability that capture.
as shown in accompanying drawing 1,2,3, the angle inserting the formation of pawl tip 6 two side ends limit is α 5 , α 5 angle between 45 ° to 60 °; The angled end-face 7 that falls is α with the angle of the vertical extrados of elasticity bailer grab 2 2 , α 2 angle between 15 ° to 45 °; Or/and, there is angle α between the inclined plane on the tip limit of falling splay end 8 and the outer ring surface of slotting pawl tip 6 4, α 4 angle between 15 ° to 30 °; Or/and, drag for the pawl limit of falling splay end 9 inclined plane and and elasticity bailer grab 2 outer ring surface between have angle α 3 ; α 3 angle between 15 ° to 30 °.
as shown in accompanying drawing 1,3, the wide footpath cylinder section of each elasticity bailer grab 2 bottom is intervally distributed with at least two briar tooths 3 vertically; The briar tooth 3 of adjacent spring bailer grab 2 is in being dislocatedly distributed, and the briar tooth 3 on whole elasticity bailer grab 2 is in spiral distribution from top to bottom.The effect of the crawl firmness improving elasticity bailer grab 2 can be played like this.
as shown in accompanying drawing 1,4, briar tooth 3 is interior helical teeth obliquely; Angle α is had between briar tooth 3 inner face and elasticity bailer grab 2 inner face 1 ; Briar tooth 3 comprises α 1 be the first briar tooth and the α of 15 ° 1 it is second briar tooth of 30 °; First briar tooth and the second briar tooth are for distribute alternatively up and down.Inside briar tooth 3 obliquely, does not hinder elasticity bailer grab 2 to be inserted in on spiral wire fish downwards; The more convenient spiral wire fish of briar tooth 3 of 15 ° and 30 ° hangs, and firmness is high.
as shown in Figure 1, the top of top connection 1 is provided with external screw thread.The utility model is facilitated to connect, easy accessibility.
as required, weighted lever is installed with in the upper end of top connection 1.In use, weighted lever is arranged between cable rope and top connection 1; Weighted lever can strengthen weight of the present utility model, and play the effect increasing and transfer impact force, improve the reliability of arresting spiral wire fish, fishing success ratio is high.
above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
