The invention relates to a double-lock single elastic clip in-place locking core-taking suspension positioning mechanism. The double-lock single elastic clip in-place locking core-taking suspension positioning mechanism is characterized in that an upper locking device and a lower locking device are arranged in the mechanism, a locking resilient pin in the upper locking device is fixed on a force transferring shaft, a locking pin sleeve is sleeved on the locking resilient pin and is respectively arranged at the inner sides of two elastic clips; two wing plates of a recovery blocking clip are arranged in blocking grooves of an elastic clip seat; touch pins in the lower locking device are arranged in pin holes of a locking sleeve and a water distribution joint; locking bolt pins are arranged in a pin hole which is transversely arranged in a feedback rod; a reset locking spring is placed between the two locking bolt pins; the touch pins are arranged in a stepped hole; a large hole of the stepped hole is formed in the locking sleeve, and a small hole of the stepped hole is formed in the water distribution joint; the locking sleeve and the water distribution joint, on which stepped holes are formed, are fixedly connected to the elastic clip seat; a suspension ring is sleeved at the lower end of the elastic clip seat; and a screw thread which is arranged at the lower end of the elastic clip seat is connected with the water distribution joint and is used for fixing the suspension ring. The double-lock single elastic clip in-place locking core-taking suspension positioning mechanism has the functions of in-place elastic clip expansion and locking; and when the double-lock single elastic clip in-place locking core-taking suspension positioning mechanism is used, the elastic clip is at a furling state and is in non-contact with a drill stem and free of abrasion; and the elastic clip expands and is ejected when being put in place and is locked by using the locking pin sleeve.
Description
technical field [0001] The invention relates to a double-lock single-ellipse clamping in place locking rope coring suspension positioning mechanism, which is used in the technical fields of geological engineering and petroleum engineering exploration. Background technique [0002] In the field of exploration technology, with the extension of ore prospecting to the deep, diamond drilling using wireline coring is gradually popularized, which brings new development opportunities for wireline coring technology, but at the same time puts forward more requirements for wireline coring technology. high demands. How to reduce the number of wearing parts of the rope coring tool, increase the service life of the rope coring tool, and improve the reliability of its work to adapt to deep hole and ultra-deep hole exploration and drilling is a technical problem that needs to be solved urgently at present. [0003] The currently used rope coring tools generally adopt the elastic card rope ...
