Retractable and carrying device for underwater test equipment

Abstract

The invention discloses a lifting and carrying device for underwater test equipment. The device comprises a full-circle slewing crane, a suspension bridge, a hydraulic clamping device and a hoisting winch; the full-circle slewing crane is installed on the deck of a hull; the suspension bridge is installed at the bottom of the crane on one boardside of the hull and hinged to the deck; the suspension bridge, and one side or two sides of the pillar body of the full-circle slewing crane are provided with pulley groups; the hoisting winch is installed on the deck of the hull; the lifting of the suspension bridge is driven by the hoist winch through the pulley groups; an installation opening is formed in the free end part of the suspension bridge; the installation opening is provided with the hydraulic clamping device; and the hydraulic clamping device is used for clamping a suspension rod connected with a rotary driving device tightly. The lifting and carrying device adopts a boardside lifting arrangement, which means the suspension bridge can be flexibly arranged on the boardside position of a water working platform without regarding the size restriction of a test wellhead of the waterworking platform, and testing for big size test equipment can be completed.

Description

technical field [0001] The invention relates to underwater test equipment, in particular to a retractable and carrying device for underwater test equipment. Background technique [0002] The release and recovery of traditional underwater test equipment mainly use forms such as A-frames, driving cranes, and cranes, but are limited by factors such as the operating area scale and general layout of the operating platform. For large-scale underwater test equipment (such as a total length of 10 ~60 meters), there is no relatively complete device in China that can realize the complete operation process of equipment assembly, hoisting, lowering, slewing drive and recycling. [0003] In the previous technical solutions, after the underwater test equipment is put into the water, there are usually the following two forms to complete the recovery: [0004] One is to use ropes to connect the test equipment with the recovery equipment on the ship. The test equipment is in a state of shak...

Problems solved by technology

[0004] One is to use ropes to connect the test equipment with the recovery equipment on the ship. The test equipment is in a state of shaking in the water, so this method is not suitable for experimental equipment with large volume and weight. When recovering, it will be difficult to recover the equipment through the rope;

[0005] The second is to use the boom to connect the test equipment to the hull. The test equipment is in a fixed state. However, since the length of the boom is fixed, it is necessary to connect several booms in sequence before the test equipment can be put into the designated position. In deep waters, when the test equipment is recovered, it is also necessary to remove the boom while recovering, and the operation process is relatively cumbersome

This method is also limited by the size of the working area, and cannot realize the retractable operation of large-scale test equipment
