The specific embodiment
As shown in Figures 1 to 6, a kind of oilfield down-hole salvager of being furnished with grab bucket, include top connection 2 and lower extension bar 4, between top connection 2 and lower extension bar 4, be connected with elastic device 3, the vertical height that can realize top connection 2 by elastic device 3 changes, salvage widerly, and elastic device 3 discharges screen resiliences after salvaging completes, and convenient collection salvaged thing.The soffit of lower extension bar 4 is provided with the both sides that 5, two transparent chambers 5 of two transparent chambers lay respectively at the soffit of lower extension bar 4, is connected with searchlight 51 in transparent chambers 5, and transparent chambers 5 is hedged off from the outer world searchlight 51, protection searchlight 51.As everyone knows, the state of oil well below in being hedged off from the outer world, light is very poor, is equipped with searchlight 51, makes to salvage well lighted, is conducive to salvaging process and carries out smoothly.The same lower end of extension bar 4 is at present connected with grab bucket 6, and grab bucket 6 is connected in the centre of the lower end of lower extension bar 4.Grab bucket 6 includes grab bucket lobe 61 and draw bar 62, draw bar 62 is connected in the upper end of grab bucket lobe 61, grab bucket lobe 61 has four, the inner surface of grab bucket lobe 61 is provided with pawl 611, pawl 611 can insert in soft thing on the one hand, realize the function of salvaging soft thing, play on the other hand further increase grasp.Draw bar 62 parts penetrate in lower extension bar 4, and the upper end of draw bar 62 is connected with pull bar 9, so pull bar 9 is also in lower extension bar 4.The upper end of draw bar 62 is provided with the first screw thread 621, is provided with the first thread groove 93, the first screw threads 621 and the first thread groove 93 and matches in the lower end of pull bar 9, through the first screw thread 621, is connected with the first thread groove 93, realizes draw bar 62 and is movably connected on pull bar 9; By the rotation of the simple application of force, grab bucket 6 can be unloaded or connected, so user can change the grab bucket 6 of different size according to the actual requirements, guarantee to salvage respond well.
Pull bar 9 upwards runs through respectively elastic device 3 and top connection 2 through lower extension bar 4, and the upper end of pull bar 9 is provided with screw thread 92, is provided with through hole 21 in top connection 2, is provided with thread groove 211 in through hole 21, and screw thread 92 matches with thread groove 211.Connection function through screw thread 92 with thread groove 211, realize pull bar 9 and be connected in top connection 2, the upper end of pull bar 9 is fixedly connected with traction rotating disk 91 simultaneously, between traction rotating disk 91 and pull bar 9, be connected with connecting rod 94, the length of connecting rod 94 is consistent with the overlay length of screw thread 92, and traction rotating disk 91 is above top connection 2.Grab bucket 6, pull bar 9, traction rotating disk 91 form the critical piece of salvaging, and the grasp of grab bucket 6 is large, can be tightly coated by salvaging thing, capture effect remarkable, and fishing success ratio is high; Soft object not only can be salvaged, also hard object can be salvaged, applied widely.During traction, along with traction rotating disk 91 counterclockwise rotates, pull bar 9 also counterclockwise rotates thereupon, makes pull bar 9 drive draw bar 62 to move down, and grab bucket 6 is opened gradually, drops on thing to be salvaged; Along with traction rotating disk 91 clockwise directions rotate, pull bar 9 thereupon also clockwise direction rotate, make pull bar 9 drive draw bars 62 to move up, grab bucket 6 is closure thing to be salvaged promptly gradually.So operation is simple, and fishing success ratio is high again.Fisher 1 coupling has bracing frame 7, bracing frame 7 includes extending foot 71 and spacing ring 72, extending foot 71 is connected to the two ends of spacing ring 72, extending foot 71 can stretch, thereby can mate different oil well depths, on simultaneous retractable leg 71, be equipped with securing member 711, after the length of the selected extending foot 71 of operator, can realize fixedly extending foot 71 by tightening fastener parts 711.Turn on securing member 711 and just can again change the height of extending foot 71.Lower extension bar 4 is reverse frustoconic, and the centre of lower extension bar 4 and spacing ring 72 match, and when fisher 1 is when pressing down, can not break away thus.Bracing frame 7 can support, fixing fisher 1, and salvage is carried out under stable state, promotes fishing success ratio.
In actual use procedure, when finding that there is foreign matter and fall into oil well, first according to the height of the depth adjustment bracing frame 7 of oil well, and by the foreign matter that 7 of bracing frames the enter oil well position of dropping.Then 1 of fisher will be drawn to rotating disk 91 and rotate to lowest part on bracing frame 7, and make to grab bucket and 6 open amplitude maximum.By extrusion spring elastic device 3, allow grab bucket 6 drop on foreign matter, after catching, the traction rotating disk 91 that starts to turn clockwise, grab bucket 6 is gradually closed.After traction rotating disk 91 is difficult to rotate, unclamp elastic device 3, fisher 1 returns to original state, and foreign matter is still firmly grasped in grab bucket 6, finally by foreign body.
These are only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this.Anyly take the utility model as basis, for solving essentially identical technical problem, realize essentially identical technique effect, done ground simple change, be equal to and replace or modification etc., be all covered by among protection domain of the present utility model.
