Matched retracting and releasing device for gravity columnar sampler

Abstract

The invention discloses a matched retracting and releasing device for a gravity columnar sampler, and relates to the technical field of marine geological sampling retracting and releasing equipment. The matched retracting and releasing device comprises a slide rail, a pulley, a counterweight bearing frame and the like; and the slide rail is fixedly connected to a deck surface through screws, the pulley is nested on the slide rail, and the counterweight bearing frame is connected with the pulley through a rotating shaft. According to the matched retracting and releasing device for the gravity columnar sampler, the arranged bidirectional motor drives a cable storage roller to rotate to unwind or wind a steel wire cable, the pulley can be driven to slide on the sliding rail, and then the gravity columnar sampler can be driven to slide towards the tail of a ship body or the interior of a deck, so that the gravity columnar sampler is conveniently distributed or recycled; and through the coupling of the pulley and the counterweight bearing frame, when the counterweight head of the gravity columnar sampler is lifted, the pulley and the counterweight bearing frame are in a vertical state,so that the gravity columnar sampler can be conveniently lowered and recovered, the gravity columnar sampler can be prevented from greatly swinging on a shaking ship, and the safety of operators is guaranteed.

Description

technical field [0001] The invention relates to the technical field of marine geological sampling retractable equipment, in particular to a supporting retractable device for a gravity columnar sampler. Background technique [0002] Gravity columnar sampler is one of the necessary equipment to obtain seabed sediment samples. It collects seabed high-fidelity columnar sediment samples and is used in marine sedimentology, marine engineering geology, seabed biology, geochemistry and other disciplines. The gravity columnar sampler's The retractable device is the infrastructure to realize the operation of the gravity column sampler, which is related to the safety and efficiency of the sampling operation. [0003] Gravity columnar sampler supporting retractable device is less, there are only a few long columnar sampler retractable devices, such as the Chinese patent of notification number CN 102336259 A discloses a kind of "long columnar sampler sideboard based on fixed bulwark hull...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a matching retractable device for the gravity columnar sampler. The gravity columnar sampler can be directly installed in the device, and the pulley is used to reciprocate the gravity columnar sampler, which solves the problem of hoisting and sampling on the shaking ship. The danger of the sampler, and the potential safety hazard of using a trolley to push the sampler to roll over, while reducing the number of people pushing the trolley and stopping the swing, improving the working efficiency and safety of the gravity columnar sampler
