Description

Technical Field

[0001] This utility model relates to the field of petrochemical storage tanks, specifically to an installation structure for a float and outriggers. Background Technology

[0002] A floating roof for an oil storage tank is a floating device that covers the surface of the liquid in the tank. It floats as the liquid level rises and falls, primarily used to reduce evaporation losses of the medium inside the tank and prevent oil and gas leaks. Through buoyancy, the floating roof isolates the liquid inside the tank from the atmosphere, thereby reducing oil evaporation losses.

[0003] The floating roof currently in use is composed of several pontoons. When it is necessary to completely release the oil in the storage tank, in order to prevent the floating roof composed of pontoons from touching the bottom, a support leg assembly is usually fixed at the bottom of the floating roof. The support leg assembly is connected to the bottom of the tank so that the floating roof is located above the bottom of the tank.

[0004] For the currently used floating boxes, such as Figures 1 to 4 As shown, each pontoon is rectangular and includes a pontoon body 1, a first connecting strip 2, a second connecting strip 3, and a third connecting strip 4. The first connecting strip 2, second connecting strip 3, and third connecting strip 4 are all located on the lower surface of the pontoon body 1. The first connecting strip 2 is arranged along the length of the pontoon body 1 and fixed to it. Three first connecting strips 2 are required along the length of the pontoon body 1, with the first first connecting strip 2 arranged along the first long side of the pontoon body 1, and the length of the first first connecting strip 2 being less than the length of the first long side. A first connecting strip 2 forms a first gap between one end and the end of the pontoon body 1, and a second gap between the other end and the end of the pontoon body 1. Two other connecting strips 2 are arranged along the second long side of the pontoon body 1, with a gap between them located at the midpoint of the length of the pontoon body 1. A first third connecting strip 4 is installed on one side of this midpoint, thus forming a first assembly opening 5 between the first third connecting strip 4, the first connecting strip 2, and the pontoon body 1. Two second connecting strips 3 are arranged along the width of the pontoon body 1 and fixed to it. One end of the first second connecting strip 3 is clearance-fitted to the end of the second first connecting strip 2, and the other end of the first second connecting strip 3 is fitted to the second third connecting strip 4 fixed to the pontoon body 1, forming a second assembly opening 6 between the second third connecting strip 4, the first first connecting strip 2, and the pontoon body 1. Similarly, a third assembly opening 7 is formed between the third third connecting strip 4, the first first connecting strip 2, and the pontoon body 1.

[0005] Through the above structure, for each float box, one assembling opening is arranged at each corner part, and one assembling opening is arranged at the middle part, when the plurality of float boxes are spliced, the adjacent three float boxes are spliced into a square accommodating part A through the assembling openings at the corners and the middle part, the leg assembly comprises a leg body 8 and a connecting seat 9, the connecting seat 9 arranged at one end of the leg body 8 is matched with the accommodating part A, and the connecting seat 9 is fastened with the third connecting strip 4 by bolts.

[0006] Firstly, during assembly, the first connecting strip 2 and the second connecting strip 3 need to be selected, and the first connecting strip 2 and the third connecting strip 4 need to be installed at specified positions, once the positions are wrongly installed, the pre-installed assembling opening cannot be formed, obviously, during fixing the first connecting strip 2 and the second connecting strip 3 with the float box body 1, more time is consumed, and the cost of the installer is increased.

[0007] Secondly, the third connecting strip 4 needs to be additionally installed at the specified position, and the third connecting strip 4 needs to be separately installed, thereby occupying time and increasing the cost of the installer.

[0008] Thirdly, during splicing of the plurality of float boxes, the pre-installed assembling opening needs to be placed at the specified position, if one of them is placed reversely, the square accommodating part A cannot be formed, and the connecting seat 9 cannot be installed. The above structure needs the installer to be highly concentrated during splicing of the plurality of float boxes, the installation is complicated, the labor intensity of the installer is increased, and once the position of the float box needs to be adjusted due to error, time is occupied, and the cost of the installer is increased. The utility model discloses a kind of installation structure of float box and leg.

[0009] The utility model provides a kind of installation structure of float box and leg, the utility model is simple and efficient.

[0010] The technical scheme solving the above technical problem is as follows:

[0011] The installation structure of float box and leg, including a plurality of float boxes, leg assembly, each float box includes float box body, second connecting strip, the second connecting strip is arranged along the width direction or length direction of float box body, the middle part of the second connecting strip is recessed to the inside of float box body, and a recessed part is formed on the second connecting strip, a bayonet is formed between the recessed part and the surface of float box body after the second connecting strip is fixed with the surface of float box body, the bayonet of the two float boxes is combined to form a receiving cavity after the adjacent two float boxes are spliced, one end of the leg assembly is inserted into the receiving cavity, and the leg assembly is fixed with the recessed part.

[0012] The mounting structure of the pontoon and the leg comprises a plurality of pontoons and leg assemblies, each pontoon comprises a pontoon body and a second connecting strip, the second connecting strip is arranged along the width direction or the length direction of the pontoon body, the second connecting strip comprises a first connecting section, an intermediate connecting section and a second connecting section, the first connecting section, the intermediate connecting section and the second connecting section are fixed with the pontoon body respectively, the intermediate connecting section is located between the first connecting section and the second connecting section, the intermediate connecting section is in a triangular shape or an arc shape, a bayonet is formed between the intermediate connecting section and the pontoon body, after two adjacent pontoons are spliced, the bays on the two pontoons are combined to form a containing cavity, one end of the leg assembly is inserted into the containing cavity, and the leg assembly is fixed with the intermediate connecting section.

[0013] In the utility model, the structure of the second connecting strip is improved, that is, a recess is formed on the second connecting strip, or the intermediate connecting section in a triangular shape or an arc shape is made in a split mode, no matter which mode is adopted, the bayonet is formed between the second connecting strip and the pontoon body, after two adjacent pontoons are spliced, the bays on the two pontoons are combined to form a containing cavity, one end of the leg assembly is inserted into the containing cavity, and the leg assembly is fixed with the intermediate connecting section. Since the bayonet is located at the two ends of the pontoon body and is arranged symmetrically, when the pontoons are assembled, the problem of whether the pontoon body is placed upside down does not need to be considered, the assembly time is saved, the energy consumption of the workers is reduced, and the production cost is reduced.
