Description

Technical Field

[0001] The utility model relates to the field of shipbuilding tooling, in particular to a single-arm bracket for a raw material pipe of a resin coating machine of an LNG ship. Background Art

[0002] The resin coating machine is an important processing equipment for the prefabrication of insulation modules of the cargo maintenance system of LNG (Liquefied Natural Gas) ships. It consists of a feed pump group and a coating machine, which are connected by a raw material pipe. The feed pump group transports the two raw materials of the resin to the coating machine through the raw material pipe. The coating machine mixes the two resins and then applies the coating on the insulation box. During the coating process, the raw material pipe is suspended above the coating machine by a bracket and moves in the coating area with the coating gun of the coating machine. The raw material pipe is composed of a high-pressure hose, a heating wire, an insulating wrapping layer and a protective jacket. Two pipes form a group. The raw material pipe is long and heavy. The internal pressure is large under working conditions and the flexibility is poor.

[0003] The original raw material pipe bracket of the glue coating machine is a fixed frame structure, which is installed above the glue coating machine frame and is generally moved by slide rails or sliders. Since the slider can only slide back and forth in the horizontal direction, in some areas, the raw material pipe will have a certain pulling effect on the glue coating gun due to the restraint of the bracket and its own hardness problem, which affects the normal operation of the glue coating gun. Usually, manual intervention is used to adjust the position of the glue coating gun, which has a greater impact on production efficiency. At the same time, the raw material pipe bracket is installed at a high position and is not easy to disassemble, which makes the shifting of the glue coating machine inconvenient.

[0004] Therefore, how to improve the follow-up performance of the raw material pipe support and improve the working efficiency of the glue coating machine is an urgent problem to be solved by personnel in this technical field. Utility Model Content

DETAILED DESCRIPTION

[0028] The following is a further detailed description of a single-arm bracket for raw material pipes of a resin coating machine for LNG ships proposed by the utility model in combination with the accompanying drawings and specific implementation methods.

[0029] The advantages and features of the present invention will become more apparent from the following description.

[0030] It should be noted that, in the present invention, relational terms such as and are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0031] like Figure 1 , Figure 2 As shown, the single-arm bracket for raw material pipes of the resin coating machine of an LNG ship is arranged on a coating machine frame 10, and includes: a connecting base 1, a column 2, a triangular swing arm 3, an intermediate swing arm 4, an end swing arm 5 connected in sequence, and a plurality of hanging components for hanging the raw material pipes of the coating machine.

[0032] The connecting base 1 is connected to the gluing machine frame 10 as the installation base of the raw material tube single-arm bracket. In a specific embodiment, the size of the connecting base 1 can be specifically designed according to the profile specifications and dimensions of the gluing machine frame 10 (for example, if the installation surface of the connecting base 1 and the gluing machine frame 10 is a rectangle, the connecting base 1 can be set as a rectangular parallelepiped made of stainless steel and fit on the gluing machine frame 10); and the installation position (surface) of the connecting base 1 can be adjusted within a certain range according to the actual working conditions of the gluing machine frame 10.

[0033] One end of the column 2 is arranged on the connecting base 1, and the other end is connected to one end of the triangular swing arm 3; specifically, the column 2 is composed of a connecting plate 21 and a column 22, one end of the connecting plate 21 is fixedly arranged on the connecting base 1, and the other end is connected to one end of the column 22; the other end of the column 22 is connected to one end of the triangular swing arm 3.

[0034] Among them, a solid core shaft is arranged inside the column 22, and the solid core shaft is used to be connected with the triangular swing arm 3, and the solid core shaft can rotate inside the column 22, so as to be used to realize the subsequent horizontal rotation function of the triangular swing arm 3.

[0035] In order to better connect the connecting plate 21 and the column 22 together, the connecting plate 21 and the column 22 are both made of stainless steel, and the two parts are welded into one.

[0036] like Figure 3 , Figure 4As shown, in order to better fix the glue coating machine frame 10, the connecting base 1, and the column 2 together, the glue coating machine frame 10 is provided with a plurality of first through holes; the connecting base 1 is provided with a plurality of second through holes 11; the connecting plate 21 is provided with a plurality of third through holes, and the first through holes, the second through holes 11 and the third through holes are arranged corresponding to each other; the glue coating machine frame 10, the connecting base 1 and the connecting plate 21 are connected and fastened by passing through the third through holes, the second through holes 11, and the first through holes in sequence through the corresponding T-slot nuts and the hexagon socket screws, and can be installed and adjusted on the glue coating machine frame 10 as needed to adapt to the working heights of different glue coating machines.

[0037] Specifically, the installation adjustment is as follows: by selecting different first through holes, second through holes 11 and third through holes, the connection base 1 and the column 2 are set at different connection heights on the gluing machine frame 10 .

[0038] In addition, the first through hole here can be replaced by a T-slot. When using a T-slot, the inner diameter of the T-slot should be set to correspond to the second through hole 11 and the third through hole to ensure that the T-slot nut and the hexagon socket screw can be stably fixed in the T-slot when they pass through the third through hole and the second through hole 11 in sequence; this method is different from the design of the aforementioned through holes in that the bottom end of the T-slot nut is located inside the glue coating machine frame 10 instead of passing through the glue coating machine frame 10 and being set at the outer end, which is beneficial to avoid contact with air and reduce the rate of oxidation.

[0039] like Figure 5 As shown, one end of the triangular swing arm 3 is connected to one end of the column 2. Specifically, the triangular swing arm 3 is composed of a vertical sleeve 31, a transverse arm 32 and a triangular reinforcement plate 33. One end of the vertical sleeve 31 is connected to the solid core shaft inside the column 22, and the other end is vertically connected to the transverse arm 32. Since the solid core shaft can rotate inside the column 22, the sleeve 31 can freely rotate horizontally about the axis center line of the column 22 under the action of the solid core shaft. When the sleeve 31 rotates, it drives the transverse arm 32 to rotate horizontally. At the same time, a triangular reinforcement plate 33 for improving the supporting strength of the triangular swing arm 3 is provided at the angle between the transverse arm 32 and the sleeve 31.

[0040] In a preferred embodiment, in order to reduce the weight of the triangular swing arm 3 and improve the appearance, a plurality of lightening holes 34 are opened on the triangular reinforcement plate 33 .

[0041] like Figure 6 As shown, one end of the intermediate swing arm 4 is connected to the other end of the triangular swing arm 3 through the first hinge shaft 71, specifically, it is connected to one end of the transverse arm 32, and the intermediate swing arm 4 can freely rotate horizontally with the axis of the first hinge shaft 71 as the center line.

[0042] The end swing arm 5 has one end connected to the other end of the middle swing arm 4 through the second hinge shaft 72, and the end swing arm 5 can freely rotate horizontally with the axis of the second hinge shaft 72 as the center line.

[0043] It should be noted here that, in a specific application, only the middle swing arm 4 can perform free horizontal rotation with the axis of the first hinge shaft 71 as the center line; or only the end swing arm 5 can perform free horizontal rotation with the axis of the second hinge shaft 72 as the center line; or the middle swing arm 4 and the end swing arm 5 can perform free horizontal rotation at the same time.

[0044] The suspension assembly is arranged at the first hinge shaft 71 and / or the second hinge shaft 72 and / or the lower end of the end swing arm 5. Because the suspension assembly is used to suspend the raw material pipe of the glue coating machine, it needs to adopt a material with good load-bearing and elasticity to effectively protect the raw material pipe from damage.

[0045] The following is a specific structure of a suspension assembly, which includes a flexible hanging rope 6, a hanging ring 8, and a shackle 9. The flexible hanging rope 6 is arranged on the hanging ring 8, and the hanging ring 8 is arranged on the first hinge shaft 71 or / and the second hinge shaft 72 or / and the lower end of the terminal swing arm 5 through the shackle 9. In order to achieve a better fixing effect, the first hinge shaft 71 or / and the second hinge shaft 72 or / and the lower end of the terminal swing arm 5 can be provided with corresponding internal threads, and the shackle 9 is replaced with a hanging ring screw, and the hanging ring 8 is fixed by the hanging ring screw to achieve a better installation effect.

[0046] In a specific embodiment, three suspension components can be selected and respectively arranged at the first hinge shaft 71, the second hinge shaft 72 and the lower end of the outermost end 5 of the end swing arm.

[0047] Because in a specific application, the flexible hanging rope 6 will directly contact the raw material tube of the glue coating machine, the flexible hanging rope 6 is made of a rubber inner tube to ensure an excellent working effect.

[0048] In specific applications, during the operation of the glue coating machine, the glue gun of the glue coating machine drags the raw material tube to move, and the three swing arms of the single-arm bracket move accordingly with the movement of the raw material tube. Since each swing arm can make corresponding horizontal rotation and swing, the raw material tube can move freely in the working area, so that it will not generate drag force on the glue coating gun of the glue coating machine, thereby improving production efficiency and solving existing problems.

[0049] The utility model meets the demand for raw material pipe supports during the operation of the resin coating machine through the application on the LNG resin coating machine. The utility model fully meets the working requirements of the resin coating machine and achieves the design purpose.

[0050] To sum up, the single-arm bracket for the raw material tube of the resin coating machine of the utility model has a simple structure, is practical and convenient, and utilizes a simple joint principle to solve the long-standing mutual interference and influence between the raw material tube of the resin coating machine and the coating gun of the coating machine, eliminates hidden dangers, and improves production efficiency.

[0051] Although the content of the utility model has been described in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as a limitation of the utility model. After reading the above content, it is obvious to those skilled in the art that various modifications and substitutions of the utility model are possible. Therefore, the protection scope of the utility model should be defined by the attached claims.
