Diving cage for underwater detection operation

Abstract

The invention relates to the field of bridge underwater detecting operation facilities, and particularly discloses a diving cage for underwater detection operation. The diving cage comprises a floating body, the floating body is formed by assembling a plurality of multipurpose floating boxes, a guiding frame is arranged on the floating body, the guiding frame extends out of the floating body, thepart, extending out of the floating body, of the guiding frame is provided with a guide rail well through hanging chains, a mobile hanging beam is arranged on the guiding frame, a hoisting system is arranged on the mobile hanging beam, the hoisting system comprises a hoist or a manual capstan which is mounted below the inner end of the guiding frame, and the cable of the hoist or the manual capstan sequentially winds around a fixed pulley mounted above the guiding frame and the mobile hanging beam, and is connected with the diving cage; and the mobile hanging beam is provided with two hangingchains for hoisting the guide rail well. The diving cage is convenient to move, a diver dives through the diving cave after the diving cage is moved and positioned, and the detection operation is carried out in the diving cage in order to avoid the impact from water flow and achieve a stable underwater position, so the smooth proceeding of the detection operation is facilitated.

Description

technical field [0001] The invention relates to the field of bridge underwater detection operation facilities, in particular to a diving cage used for underwater detection operations. Background technique [0002] In the main artery of railway transportation, the underwater structure of railway bridges is an important part to ensure the safety of bridges. According to statistics, by the end of 2016, there were 75,545 railway bridges across the country, of which 27,531 bridges had entered the aging period for more than 25 years. At the same time, affected by flood erosion, impact of ice floes, and microbial corrosion, there are potential safety hazards to varying degrees. Early detection of underwater diseases of railway bridges and timely treatment are the fundamental measures to avoid safety accidents. [0003] In the current underwater detection operations, divers wear light diving equipment and dive to the predetermined position for detection. Underwater alone cannot m...

Problems solved by technology

[0003] In the current underwater detection operations, divers wear light diving equipment and dive to the predetermined position for detection. Underwater alone cannot maintain a stable posture for a long time, and cannot continue to work. When the impact of the water flow is too large, it is even impossible to conduct underwater detection and photography of pier body diseases, resulting in the unsmooth implementation of underwater inspection operations.
