Description

Technical Field

[0001] The present invention relates to the technical field of air bag lifting devices, and in particular to a novel air bag lifting device. Background Art

[0002] Currently, most platforms' pontoons are repaired by hoisting them to the shore. If the building on the platform is too heavy, it will be impossible to repair it, and the entire platform and building will be directly scrapped. In addition, the hoisting and repair process is extremely long and difficult, so it is necessary to solve the problem of controllable lifting and lowering of the pontoon platform.

[0003] The existing lifting and lowering of pontoon platforms requires electricity and manpower to operate, which is time-consuming and labor-intensive. For example, the application No. 200580017237.X discloses the use of pontoons as auxiliary equipment to ballast an offshore platform. During use, the lifting and lowering of the pontoon platform requires a large amount of electricity and manpower, which is inconvenient when the lifting platform carries a large amount of heavy objects.

[0004] Therefore, it is necessary to invent a novel air bag lifting device to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a novel air bag lifting device to solve the problem that the floating platform is difficult to maintain in the technology and cannot overcome the problem that it is easy to shake due to the buoyancy of water.

[0006] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: a novel airbag jacking device, comprising a device main body, an electric control box, an air pump, a buoy platform and a protection frame, the device main body being electrically connected to the electric control box, the electric control box being provided with a heat dissipation hole, the device main body being provided with an air pump, the air pump being fixedly connected to the buoy platform, the buoy platform being connected with a protection frame, a spring rod being provided on the protection frame, the spring rod being connected with an anti-slip pad, the protection frame being fixedly connected with an iron ring, the iron ring being provided with an iron chain, an airbag being provided in the anti-slip pad, the airbag being installed with an inlet valve and an outlet valve, a limiting column being installed on the protection frame, a jack being provided in the buoy platform, an elastic column being provided on the limiting column, a steel ball being provided on the elastic column, a No. 1 spring being connected to the No. 1 spring, a No. 1 sliding plate being connected to one end of a No. 2 spring, and the other end of the No. 1 sliding plate being fixedly connected to the No. 2 sliding plate.

[0007] Preferably, the electric control box is provided with a controller, a motor and a transmission mechanism, and the electric control box is located on land.

[0008] Preferably, the buoy platform is set in the water, and the protective frame is made of stainless steel, and there are multiple protective frames, each of which is provided with a spring rod, and there are multiple spring rods, which are distributed in a circular array about the center of the airbag. The anti-slip pad is annular, and its curvature matches the curvature of the end of the airbag.

[0009] Preferably, the air inlet valve is connected to an air pump via a gas pipeline, and the air pump is electrically connected to an electric control box.

[0010] Preferably, the depth of the insertion hole is adapted to the length of the limiting column, and the shape of the insertion hole is consistent with the combined shape of the limiting column and the elastic column.

[0011] Preferably, a plurality of elastic columns are provided, and the plurality of elastic columns are respectively provided on two opposite side surfaces of the limiting column, and the lengths and diameters of the plurality of limiting columns are the same.

[0012] Preferably, the elastic index of the No. 1 spring and the No. 2 spring is the same, and the No. 1 spring is fixedly connected to the No. 1 sliding plate, and the No. 2 spring is fixedly connected to the No. 2 sliding plate.

[0015] 1. By using this jacking device, the platform can be directly lifted above the horizontal plane to replace the damaged pontoon platform, saving the time and cost of lifting. The device is quick and easy to install and easy to maintain. If the airbag is damaged, the gas is emptied, it is removed from the protective frame, and a new airbag is replaced and inflated to resume use.

[0016] 2. The elastic connection between the protection frame and the airbag can not only fix the airbag and prevent it from drifting away, but also provide real-time protection for the airbag.

[0029] The electric control box 2 is equipped with a controller, a motor and a transmission mechanism, and the electric control box 2 is located on land, the pontoon platform 5 is located in the water, and the protective frame 6 is made of stainless steel, and there are multiple protective frames 6, each of which is provided with a spring rod 7, and there are multiple spring rods 7, which are distributed in a circular array about the center of the airbag 11. The anti-slip pad 8 is annular, and its curvature matches the curvature of the end of the airbag 11.

[0030] The air intake valve 12 is connected to the air pump 4 through a gas pipeline, and the air pump 4 is electrically connected to the electric control box 2. The depth of the socket 15 is adapted to the length of the limit column 14, and its shape is consistent with the shape of the limit column 14 and the elastic column 16 combined. There are multiple elastic columns 16, and the multiple elastic columns 16 are respectively arranged on two opposite sides of the limit column 14, and the lengths and diameters of the multiple limit columns 14 are the same.

[0031] The elastic index of the No. 1 spring 18 and the No. 2 spring 20 is the same, and the No. 1 spring 18 and the No. 1 sliding plate 19 are fixedly connected, and the No. 2 spring 20 and the No. 2 sliding plate 21 are fixedly connected.

[0032] Working principle of the present invention:

[0033] Refer to the instruction manual Figure 1-5 When using this device, first install the buoy platform 5 and the protection frame 6, insert the air pump 4 on the protection frame 6 into the socket 15, and then use the iron ring 9 on the protection frame 6 to hang the iron chain 10 on the iron ring 9 to ensure that the multiple protection frames 6 will not shake due to the buoyancy of the water. Finally, fix the multiple protection frames 6, and finally place the two ends of the uninflated air bag 11 into the anti-slip mat 8;

[0034] Refer to the instruction manual Figure 5-7 When using the device, after the installed pontoon platform 5 is placed in the water, the air inlet valve 12 on the airbag 11 is connected to the air pump 4, which is then connected to the electric control box 2. The controller and motor in the electric control box 2 send a start signal to the air pump 4, and the air pump 4 starts to inflate the airbag 11, and the pontoon platform 5 that was originally submerged in water or floating on the water surface is continuously raised (because the volume of the airbag 11 is continuously increasing, the pontoon platform 5 and the protective frame 6 are continuously raised from the water surface), which solves the problem that when the weight on the pontoon platform 5 is heavy and it is difficult to lift and carry for maintenance;

[0035] After lifting the buoy platform 5 and the protection frame 6, the airbag 11 can be replaced or the protection frame 6 can be disassembled. When disassembling the protection frame 6, it is only necessary to press the direction of any limit column 14 with your hand, squeezing the No. 1 spring 18 in the elastic column 16 to drive the No. 1 sliding plate 19 and the No. 2 spring 20 to operate, and finally push the No. 2 sliding plate 21 to form a buffering elastic potential energy in the elastic column 16, leaving a gap between the elastic column 16 and the limit column 14 from the socket 15, so that the limit column 14 is loose in the socket 15, and the limit column 14 can be easily taken out of the socket 15.
