DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0017] like Figures 1 to 3 As shown, it is an embodiment of the utility model, a lifting mechanism of an offshore working platform 1, comprising:

[0018] An offshore work platform 1, wherein a lifting cylinder 8 is provided at the center of the offshore work platform 1, wherein a plurality of lifting slots 81 are provided on the lifting cylinder 8, wherein the offshore work platform 1 is fixedly connected to a hydraulic cylinder 2, wherein the hydraulic cylinder 2 is fixedly connected to a lifting box 3, wherein the lifting box 3 is slidably connected to a magnet 5, wherein the magnet 5 is fixedly connected to a support member 6, wherein an elastic member 4 is provided in the lifting box 3;

[0019] Magnet 2 7 , wherein the magnet 2 7 is arranged on a side of the hydraulic cylinder 2 away from the lifting cylinder 8 , and the magnet 2 7 is fixedly connected to the hydraulic cylinder 2 9 , and the hydraulic cylinder 2 9 is fixedly connected to the offshore working platform 1 .

[0020] In this embodiment, the elastic member 4 can be a spring, and the elastic member 4 is in a compressed state. The lifting slot 81 includes a slot 811 and a limit slot 812. The support member 6 includes a plug plate 61 and a limit block 62. The plug plate 61 is fixedly connected to the magnet 5, and the plug plate 61 is fixedly connected to the limit block 62. The hydraulic cylinder 2, the lifting box 3, the elastic member 4, the magnet 5, the support member 6, the magnet 2 7 and the hydraulic cylinder 2 9 are in a certain number, and the hydraulic cylinder 2, the lifting box 3, the elastic member 4, the magnet 5, the support member 6, the magnet 2 7 and the hydraulic cylinder 2 9 are evenly distributed around the lifting cylinder 8; the magnet 2 7 can be a non-permanent magnet, and the magnetization of the non-permanent magnet is an existing mature technology, so it will not be described in detail; ... The lowering box 3, the elastic member 4, the magnet 1 5, the support member 6 and the magnet 2 7 are evenly divided into two groups, and the hydraulic cylinder 1 2, the lifting box 3, the elastic member 4, the magnet 1 5, the support member 6 and the magnet 2 7 are arranged at intervals and set as the same group, and the same structure in the same group has the same height, and the groups are respectively the first group and the second group. Assuming that the support member 6 and the lifting cylinder 8 of the first group are inserted into the lifting groove 81 to support the lifting cylinder 8, that is, the plug plate 61 is inserted into the slot 811 and the limit block 62 is inserted into the limit groove 812, when the lifting cylinder 8 needs to be lowered, the hydraulic cylinder 2 9 drives the magnet 2 7 to descend to a preset height, the hydraulic cylinder 1 2 in the first group drives the lifting box 3 to descend, and the lifting box 3 drives the elastic member 4, the magnet 1 5 and the support member 6 to descend synchronously and then drives the lifting cylinder 8 to descend, and When the lifting cylinder 8 is lowered to the preset height, the hydraulic cylinder 12 in the second group drives the lifting box 3 and the elastic member 4, magnet 15 and support member 6 thereon to rise to the preset height, magnet 15 rises away from magnet 27, magnet 27 loses its adsorption to magnet 15, and the magnet 15 is reset under the action of the elastic member 4, and the magnet 15 drives the support member 6 to reset, and the support member 6 contacts the side wall of the lifting cylinder 8. When the first group drives the lifting cylinder 8 to descend to the preset height, the support member 6 in the second group is inserted into the support groove under the action of the elastic member 4. At this time, the first group continues to drive the lifting cylinder 8 to descend to the preset position. At this time, the limit block 62 of the support member 6 of the second group is completely inserted into the limit groove 812, and the support member 6 supports the lifting cylinder 8, and due to the limit block 62 of the first group and the limit groove 812 The first group of hydraulic cylinders 1 and 2 are in a state of being unable to attract and drive the magnet 1 to compress the elastic member 4 and drive the support member 6 away from the lifting cylinder 8. At this time, the first group of hydraulic cylinders 1 and 2 are rapidly descending (the speed is greater than the descending speed of the second group of hydraulic cylinders 1 and 2) and are separated from the lifting cylinder 8, so that the limit block 62 is separated from the limit groove 812. At this time, the support member 6 of the second group supports the lifting cylinder 8, and the second group of hydraulic cylinders 1 and 2 drive the lifting cylinder 8 to descend. The first group of magnets 1 and 2 attract the magnet 1 and 5, so that the support member 6 moves linearly and is separated from the lifting cylinder 8. Then the first group of hydraulic cylinders 1 and 2 are raised to a preset height. Similarly, the magnet 1 and 5 are raised away from the magnet 2 and 7, and the magnet 2 and 7 lose their adsorption to the magnet 1 and 5. The principle is the same as above. This cycle is repeated to achieve the continuous descent of the lifting cylinder 8.

[0021] When the lifting cylinder 8 needs to rise, the hydraulic cylinder 2 9 drives the magnet 2 7 to rise to a preset height, and the hydraulic cylinder 1 2 of the first group drives the support member 6 to rise through the lifting box 3 and then drives the lifting cylinder 8 to rise. When the lifting cylinder 8 rises to the preset height, the magnet 2 7 attracts the magnet 1 5, and due to the cooperation between the limit block 62 and the limit groove 812, the support member 6 cannot be driven to lift the lifting cylinder 8, and at this time, the support member 6 of the second group is inserted into the support groove of the lifting cylinder 8, and the hydraulic cylinder of the second group drives the support member 6 through the lifting box 3, and the support member 6 drives the lifting cylinder 8 to rise At this time, the limit block 62 of the first group is separated from the limit groove 812, and the magnet 2 7 attracts the magnet 1 5 to make the support member 6 away from the lifting cylinder 8. The hydraulic cylinder drives the support member 6 to drop to a preset height through the lifting box 3. The magnet 1 5 is separated from the magnet 2 7. The magnet 1 5 is reset to contact the side wall of the lifting cylinder 8 under the action of the elastic member 4 until the second group drives the lifting cylinder 8 to rise to the preset height. The support member 6 in the first group is inserted into the support groove under the action of the elastic member 4, and the above operation is repeated until the lifting cylinder 8 rises to the preset height to achieve continuous rise.

[0022] In summary, the device changes the height of magnet 2 7 before the lifting cylinder 8 descends or rises, and cooperates with hydraulic cylinder 1 2, lifting box 3, elastic member 4, magnet 1 5, support member 6 and hydraulic cylinder 2 9 in the first group and the second group to achieve continuous lifting of the lifting cylinder 8, which has the advantage of high lifting efficiency.
