Description

Technical Field

[0001] The utility model relates to an auxiliary installation device for a floating drum foot, in particular to an installation and positioning device for a floating drum foot. Background Art

[0002] As we all know, during waterway management, navigation lights usually need to be installed on top of a buoy, which is in turn installed on the surface of a buoy drum. During installation, the footing needs to be welded to the buoy drum. During initial installation, the footing is usually welded onshore or in a factory, which generally allows for quick installation. However, during subsequent actual use, when the footing is damaged, completely damaged, or only one foot remains, navigation aid maintenance personnel will need to perform on-site welding on the buoy drum. For example, in Jiangsu Province, navigation aids are mainly buoy drums. Although the number of buoy strikes has decreased in recent years, the total number is still high throughout the year. When a buoy drum is hit by a ship, both the buoy and the footing will be damaged. When restoring the navigation aid, the footing needs to be repositioned and welded.

[0003] At present, the conventional operation method is: first weld a foot on the floating drum, then hoist the floating frame onto the floating drum, determine the position of the other floating frame feet according to the welded floating frame feet, then hoist the floating frame, weld the remaining three floating frame feet, and after all four floating frame feet are welded, finally adjust the floating frame to the floating frame feet and install and fix them. The whole process requires one person to operate the crane, three people to hold the floating frame, and one person to weld the feet, a total of 5 people. The manpower demand is high and the operation is difficult (the floating frame needs to be hoisted repeatedly during the operation, which is time-consuming and labor-intensive), thereby making its work efficiency low. In addition, the floating frame needs to be hoisted many times during the operation. The gantry is used to adjust the position of the base. If a ship approaches or the wind and waves are strong, the staff need to climb the gantry to untie the slings, which makes it impossible for the working ship to avoid in time. At the same time, due to the large size of the gantry, many people stand on the surface of the buoy holding the gantry, and the space is limited. The wind and waves cause the gantry to shake, and there is a risk of people falling into the water. Therefore, there are still great safety hazards, especially in Jiangsu Province where the wind and waves on the river are strong. The gantry has to be hoisted many times to adjust the position of the base, which affects the efficiency of navigation mark recovery and greatly increases the safety risks. In addition, the traditional method requires welding the base one by one, which makes the welding position easy to offset, and the welding position accuracy and welding quality are also affected. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a floating drum foot installation and positioning device to solve the problems of high safety hazards, large manpower requirements, inaccurate foot positioning and low work efficiency in the installation process of the floating drum foot.

[0005] In order to solve the above technical problems, the floating drum base foot installation and positioning device of the present invention includes a support frame adapted to the shape of the enclosed surface formed by the bottom support legs of the floating frame, and a plurality of support legs arranged at the corners of the support frame and used to support the support frame; the arrangement position of each support leg matches the welding position of each base foot of the floating drum, and can make each support leg just located on the inner side of the welding position of the base foot of the floating drum when the support frame is placed on the surface of the floating drum.

[0006] Each of the supporting legs is vertically welded to each corner of the supporting frame.

[0007] The height of the supporting legs is 25cm-35cm.

[0008] Adjacent sides of the support frame are reinforced and fixed by using transverse support rods.

[0009] An oblique support rod is provided between the support frame and each of the supporting legs.

[0010] The horizontal cross-section of the support frame is a square.

[0011] The bottom of the support foot has an arc-shaped surface adapted to the shape of the upper surface of the floating drum.

[0012] The support frame is made of stainless steel.

[0013] The support frame is made of aluminum alloy.

[0014] The advantages of the utility model are:

[0015] By cleverly designing a support frame that is adapted to the shape of the enclosed surface formed by the bottom legs of the floating frame, and a positioning device composed of multiple legs arranged at the corners of the support frame and used to support the support frame, it can completely simulate the specific position of the bottom legs of the floating frame, so as to use this as a reference for quickly and accurately positioning and welding the various bottom legs of the floating drum. On the one hand, its installation accuracy is very high, ensuring that the floating frame can be installed smoothly and securely, and also ensuring the long-term use of the bottom legs. On the other hand, there is no need to repeatedly use a crane to lift the floating frame for bottom leg adjustment during the entire welding process, and a single person can operate it. It greatly reduces the demand for manpower, and eliminates the need to repeatedly lift the floating frame during the operation, thereby effectively reducing the labor intensity of workers and saving a lot of time and energy, greatly improving the operation efficiency. Because only one person is required to operate the entire process and there is no influence of the floating frame during the work process, the probability of workers falling into the water is also greatly reduced, avoiding the possibility of multiple people standing on the floating drum to operate and people falling into the water. On the other hand, even when the wind and waves are strong or the ship is approaching, the workboat can be quickly detached without worrying about the safety risks of the lifting operation, further effectively avoiding the safety hazards existing in the traditional lifting and welding process.

[0019] The floating drum foot installation and positioning device of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0020] like Figure 1 As shown, the floating drum foot installation and positioning device of the present invention includes a support frame 2 that is adapted to the shape of the enclosed surface formed by the bottom support legs of the floating frame 1, and a plurality of support legs 3 that are arranged at the corners of the support frame and are used to support the support frame; in this embodiment, the support frame 2 is a rectangular structure, that is, the horizontal cross-section of the support frame 2 is a square, and the support legs 3 are vertically welded to the corners of the support frame 2. The height of each support leg 3 is 25cm-35cm at best. Through support legs of different heights, the installation requirements of different floating drums for foot heights can be adapted. The outline and area of the support frame 2 are consistent with the outline and area of the enclosed surface formed by the bottom support legs of the floating frame 1, and the arrangement position of each support leg 3 matches the welding position of each foot 4 of the floating drum. Since the bottom support legs of the floating frame 1 need to be positioned and installed on the inner side of the foot 4, in fact, the enclosed area formed by each support leg 3 is actually The bottom legs 4 of the buoy are fixed to the bottom of the buoy and are then fixed to the bottom of the buoy. Figure 3 is a schematic diagram after installation, the floating drum is not shown).

[0021] Furthermore, in order to improve the stability of the entire structure, adjacent sides of the support frame 2 are reinforced and fixed with transverse support rods 5 , and diagonal support rods 6 are provided between the support frame 2 and each support leg 3 .

[0022] Furthermore, considering that the surface of the floating drum is not flat but has an arc, the bottom of the support leg 3 has an arc surface adapted to the shape of the upper surface of the floating drum so that it can better fit on the surface of the floating drum.

[0023] Furthermore, the support frame 2 can be made of stainless steel, which has good corrosion resistance and long-term reliability. Of course, considering that the support frame made of stainless steel is relatively heavy and inconvenient to carry and use, in order to reduce its overall weight, it can also be made of aluminum alloy.

[0024] Application effect: During the specific test, the Channel 13106 shift group conducted a practical test on the #T1 black buoy. The Channel 13106 shift group used the remaining foot on the buoy to place the buoy foot installation and positioning device of the present invention, quickly located the positions of the remaining three footings, and then carried out welding operations. At the same time, the time was recorded for comparison with the traditional welding method. Finally, it was concluded that compared with the traditional positioning method, the buoy foot installation and positioning device of the present invention can quickly locate the four positions of the buoy foot, greatly improving the speed of navigation mark recovery. It not only has higher positioning efficiency and lower safety risks, but also reduces manpower requirements. After testing, it takes 60 minutes to complete the entire process of foot positioning, welding, and installation using the traditional method, while it only takes 30 minutes using the buoy foot installation and positioning device of the present invention, with significant results.
