Abstract
The utility model relates to a sliding underground guider for resistance of an underground pipe appliance of a guiding logger. The sliding underground guider for resistance is a piston mechanism with an annular space in the middle, and the annular space is formed by inserting a piston rod in a piston tube in sliding fit. The lower end of the piston rod is provided with a screw hole matched with a fastening screw and limiting the piston tube to the lower portion of the piston rod. Sliding seats are respectively sleeved at two ends of the annular space, the two sliding seats are oppositely provided with at least three movable arms in a hinge mode, two corresponding movable arms are hinged, a supporting spring is arranged between the two sliding seats, and two ends of the piston mechanism are respectively provided with a connector. Movable arms and a wheel support mechanism are adopted. When resistance occurs, the movable arms are unfolded by the resistance force in order to adjust and centralize the equipment, and the guider continues to be laid down. When the resistance is overcome, the movable arms are folded by the spring, and the guider is laid down normally. The sliding underground guider for resistance has the advantages of being simple in structure, convenient in use, safe and reliable.
Description
Technical field
The utility model relates to the supporting aid of logging technique field, specifically is a kind of slidingtype down-hole that guides logger to enter down-hole pipe guider that is hampered.
Background technology
Present continuous development along with the oil field development technology; big gradient oil gas open hole well is also more and more, and original like this logger adopts in the process of normal cable below, and it is irregular to run into well track through regular meeting; be the situation that dog-leg is spent height, step sudden change, causing can't logging operation.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of slidingtype down-hole simple in structure, that efficiently guide logger to go into the well guider that is hampered is provided.
Its technical scheme is: pegged graft to be slidingly matched by piston rod and piston cylinder and form the middle piston mechanism that has annular space, wherein piston-rod lower end is provided with screwed hole, with the bottom that piston cylinder is limited to after lock-screw cooperates piston rod, be set with at the annular space two ends and decide sliding seat, two sliding seats are distinguished hinge in opposite directions by 3 above lever arms, hinge between Dui Ying two lever arms is provided with support spring between two sliding seats in opposite directions, and the two ends of piston mechanism are respectively equipped with connector.
Also comprise in the such scheme: be connected with roller simultaneously at each corresponding in opposite directions lever arm hinge place.The first end of the connection at piston mechanism two ends is the screwed connection head, and the other end is a conical head.On the screwed connection head, be provided with helmet.
The utility model adopts lever arm and idler wheel support structure, and when it was hampered, lever arm promoted lever arm and opens under drag effect, reaches the adjustment instrument with this and sets upright between two parties, and guide instrument continues to transfer; When instrument overcome be hampered after, lever arm recovers to pack up under spring action, guide instrument is normally transferred.The utlity model has advantage simple in structure, esy to use, safe and reliable.
Description of drawings
Fig. 1 is the structure chart of a kind of state embodiment that is hampered of the utility model;
Fig. 2 is a conventional structure graph among Fig. 1.
Among the figure, the 1st, helmet, the 2nd, piston rod, the 3rd, sliding seat, the 4th, lever arm, the 5th, roller, the 6th, spring, the 7th, bearing pin, the 8th, piston cylinder, the 9th, spring washer, the 10th, lock-screw, the 11st, (glue) conehead.
The specific embodiment
See figures.1.and.2, a kind of slidingtype down-hole guider that is hampered, peg graft to be slidingly matched by piston cylinder 8 and piston rod 2 and forms the piston mechanism that the centre has annular space, wherein: piston rod 8 leading sections all have projection, the lower end is provided with screwed hole, with the bottom that piston cylinder 8 is limited to after lock-screw 10 and spring shim 9 cooperate piston rod 2.At the end of annular space suit sliding seat 3, be slidingly matched with piston cylinder 8 and the formation of piston rod 2 outer walls in the annular space, hinge is by 6 lever arms 4 respectively in opposite directions for two sliding seats 3, and hinge between Dui Ying two lever arms 4 is provided with support spring 6 between two sliding seats 3 in opposite directions.Whole like this lever arm 4 is free to slide in annular space together with sliding seat and rotates.
The further perfect scheme of the foregoing description also comprises: be connected with roller 5 simultaneously at each corresponding in opposite directions lever arm hinge place.
The first end of the connection at piston mechanism two ends is the screwed connection head, and the other end is a conical head (being the glue conehead) 11.On the screwed connection head, be provided with helmet 1.
Claims (3)
1. slidingtype down-hole guider that is hampered, it is characterized in that: peg graft to be slidingly matched by piston rod and piston cylinder and form the middle piston mechanism that has annular space, wherein piston-rod lower end is provided with screwed hole, with the bottom that piston cylinder is locked in after lock-screw cooperates piston rod, be set with at the annular space two ends and decide sliding seat, two sliding seats are distinguished hinge in opposite directions by 3 above lever arms, hinge between Dui Ying two lever arms in opposite directions, be provided with support spring between two sliding seats, the two ends of piston mechanism are respectively equipped with connector.
2. the slidingtype according to claim 1 down-hole guider that is hampered is characterized in that: be connected with roller simultaneously at each corresponding in opposite directions lever arm hinge place.
