Although it has a good fixing effect, when the fuel tanks are disassembled, repaired or replaced, welding and cutting are the only options, which is relatively cumbersome. In addition, since the lengths of the fuel tanks are different, when installing the fuel tanks, a matching support frame must be used to adjust the support spacing and then welded and fixed for installation, which is inconvenient to use. Based on the deficiencies of the prior art, the present invention designs a bracket structure for a ship fuel tank. Summary of the invention

[0026] Working principle: when a support structure of a ship fuel tank is used, in the initial state, the fixing plate 101 is fixed to the bottom of the base 1, and the fixing block 102 installed on the fixing plate 101 is provided with a mounting hole 103 to facilitate fixing the base 1, and the slide groove 2 and the inner groove 201 opened on the base 1 are connected by a threaded rod 202 which is rotatably connected by a motor 203, and the threaded rod 202 is connected to an adjustment seat 302 which is slidably connected to the inner groove 201, and a side bracket 303 is connected to the top of the adjustment seat 302, and both ends of the side bracket 303 are supported by a rotating wheel 306 for rolling.

On the bracket 401, the first clamping arm 403 and the second clamping arm 405, which are connected step by step through the first rotating shaft 402 and the second rotating shaft 404, are both provided with anti-slip pads 406 on the inner sides. The first clamping arm 403 and the second rotating shaft 404 are respectively connected to the first telescopic cylinder 409 and the second telescopic cylinder 412, so as to control the first clamping arm 403 and the second clamping arm 405 to rotate inward or expand to clamp and fix fuel tanks of different sizes. When it is necessary to clamp and fix fuel tanks of different sizes, first, the first telescopic cylinder 409 and the second telescopic cylinder 412 are contracted to pull the first clamp arm 403 and the second clamp arm 405 to rotate and expand outward, and then the fuel tank is hoisted onto the two sets of brackets 401 and fixed to the anti-slip pad 406.

At this time, the motor 203 drives the threaded rod 202 to rotate, and uses the threaded groove 311 to push the two sets of adjustment seats 302 and the sliding seat 301 to move to the inside or outside of the two ends of the base 1 under the sliding support of the rotating wheel 306, and drive the clamping mechanism 4 to move and adjust the spacing until the spacing between the two sets of clamping mechanisms 4 is the same as the spacing between the fixed points measured in advance. After the adjustment is completed, the telescopic top rod 308 extends out to push the anti-skid clamp plate 309 to snap into the locking plate 310 to lock the position of the sliding seat 301 and the clamping mechanism 4. This device is convenient for clamping and fixing fuel tanks of different lengths.
