Technical Field

[0001] The invention belongs to the technical field of uranium exploration, and in particular relates to a well logging probe salvaging device for uranium exploration. Background Art

[0002] Uranium ore exploration is to carry out geological, geophysical, geochemical exploration, mining technical conditions and other work in accordance with the mineralization characteristics of deposits of different genetic types, and to intensify exploration projects so as to determine the continuity of the main ore body or major ore body.

[0003] Well logging is an indispensable technical means in geological exploration. Due to the complex geological conditions underground, drilling technology, drilling mud and other factors, hole wall collapse and rock falling often occur during the logging process, causing instruments and equipment to fall to the bottom of the well. Since the instruments and equipment may be hung with radioactive sources, the fallen logging probes must usually be salvaged;

[0004] However, logging probe tubes are generally heavy, long, and have smooth outer walls, making them difficult to salvage using traditional methods. Different drilling rig tool joint models are not completely consistent, so it is impossible to manufacture a unified salvage device. Therefore, a logging probe tube salvage device for uranium exploration is needed to solve the above problems. Summary of the invention

Through grooves 24 are provided in the plurality of first racks 23. By arranging the pull rods 21 and the tube body 11, since the pull rods 21 are slidably connected in the tube body 11, the tube body 11 and the pull rods 21 cooperate with each other to limit the moving pull plate 22, so that the pull plate 22 can move smoothly along the axial direction of the pull rods 21.

[0031] The clamping assembly 3 includes connecting rods 31, the bottom ends of several connecting rods 31 are hinged to the first rack 23 through pins, and the top ends of several connecting rods 31 are hinged to the clamping plate 32 through pins;

[0033] The second rack 43 is disposed in the cavity 14, and the second rack 43 is disposed in the through slot 24. By providing the second rack 43 and the through slot 24, the moving first rack 23 can drive the through slot 24 to move outside the second rack 43, and the first rack 23 provided with the through slot 24 will not interfere with the moving second rack 43;

[0034] The limiting assembly 5 includes a limiting block 51 and a limiting groove 52. A plurality of limiting blocks 51 are respectively connected to a surface away from a plurality of first racks 23. A plurality of limiting blocks 51 are slidably connected in the limiting groove 52. By setting the limiting groove 52 and the limiting block 51, since the limiting block 51 is slidably connected in the limiting groove 52, the limiting block 51 and the limiting groove 52 cooperate with each other to limit the first rack 23, so that the moving first rack 23 can move smoothly along the direction of the limiting groove 52.

[0035] A plurality of limiting grooves 52 are provided in the tube body 11. The first gear 41 and the second gear 42 are both rotatably connected in the cavity 14. The size of the first gear 41 is smaller than that of the second gear 42. The first gear 41 and the second gear 42 are arranged above the second rack 43.

[0036] The clamping plate 32 is slidably connected in the first receiving groove 12, and the first receiving groove 12 is arranged above the second receiving groove 13. By arranging the clamping plate 32 and the first receiving groove 12, since the clamping plate 32 is slidably connected in the first receiving groove 12, the first receiving groove 12 can limit the clamping plate 32. When the rotating connecting rod 31 pushes or pulls the clamping plate 32, the moving clamping plate 32 can move smoothly along the direction of the first receiving groove 12.

[0037] The pull plate 22 is shaped as a circular ring and is disposed in the cavity 14. By providing a second receiving groove 13 and a second rack 43, since the second rack 43 is slidably connected in the second receiving groove 13, the second receiving groove 13 can limit the moving second rack 43 so that the second rack 43 does not shake during movement, and the second rack 43 can move smoothly along the direction of the second receiving groove 13 under the action of rotating the second gear 42.

[0038] The working principle and use process of the present invention are as follows: when the device needs to be used, the salvage pipe 1 is lowered into the wellhead where the instrument needs to be salvaged, a plurality of pull rods 21 are connected to the external wire rope, the salvage pipe 1 is dropped to the bottom of the wellhead, and inserted into the ground at the bottom of the wellhead, and the probe enters the salvage pipe 1, at which time the bottom of the salvage pipe 1 is slightly lower than the probe;

[0039] A plurality of pull rods 21 are pulled upward by the wire rope, and the plurality of pull rods 21 moving upward drive a plurality of first racks 23 to move upward through the pull plates 22, and the first racks 23 moving upward drive a plurality of clamping plates 32 to approach each other through a plurality of connecting rods 31, and the plurality of clamping plates 32 approaching each other are in close contact with the outer surface of the probe tube, and the probe tube is fixed in the salvage tube 1 at this time, and the first rack 23 moving upward drives the first gear 41 to rotate at the same time, and the plurality of rotating first gears 41 drive a plurality of second racks 43 to approach each other through the second gear 42, and the adjacent ends of the plurality of second racks 43 approaching each other move into the tube body 11 and contact with the bottom of the probe tube in the tube body 11, and when the probe tube is fixed, the pull rods 21 pulled upward can synchronously drive the salvage tube 1 to move upward, and the salvage tube 1 moving upward drives the probe tube to move out of the wellhead;

[0040] The wire rope is loosened, and the pull plate 22 drives the first racks 23 to move downward under its own weight, so that the clamps 32 and the second racks 43 move away from each other, so that the clamps 32 and the second racks 43 are separated from the probe, and then the probe can be smoothly removed from the salvage pipe 1.
