Description

Technical Field

[0001] The utility model mainly relates to the technical field of LNG gas tank internal processing, and particularly relates to an LNG gas tank inner liner winding device. Background Technique

[0002] Generally, vehicles using LNG gas tanks are mainly heavy trucks, long-distance buses, buses and other vehicles that require a large amount of energy supply and have certain requirements for environmental protection performance. LNG is lower in price than traditional fuels such as diesel, which can reduce the operation cost of vehicles. Moreover, the pollutants generated after combustion are far lower than those of traditional fuels such as diesel, which is beneficial to reducing air pollution and protecting the environment.

[0003] The LNG gas tank generally has two layers of structures, namely an inner liner and an outer shell, which can not only improve the structural strength but also improve the heat preservation performance. The inner liner of the LNG gas tank needs to be wound with a heat insulation belt. In the prior art, the heat insulation belt with the same width as the inner liner of the LNG gas tank is used for winding. Therefore, different widths of heat insulation belts need to be formulated according to the width specifications of the heat insulation belts, and the overall cost is relatively high. Moreover, when winding the inner liners of LNG gas tanks with different width specifications, it is necessary to replace the winding drums with corresponding specifications, resulting in high labor intensity and affecting the overall production efficiency.

[0025] Refer to the attachedFigure 1-2 , an LNG gas tank inner liner winding device, including a base 1, on which a clamping mechanism 2 and a reciprocating mechanism 3 are arranged;

[0026] The clamping mechanism 2 includes movable plates 21, the number of the movable plates 21 is two, and they are driven to move relatively. Connecting rods 22 are rotatably installed on both of the movable plates 21. Arc-shaped clamping plates 24 are fixedly installed at the opposite ends of the two connecting rods 22, and a first motor 23 is assembled at the other end of one of the connecting rods 22;

[0027] The reciprocating mechanism 3 includes a rotating bracket 31, on which a winding drum 32 is rotatably installed. The rotating bracket 31 is driven to make a reciprocating motion, and the moving direction is the same as that of the movable plate 21.

[0028] In this embodiment, after the LNG gas tank inner liner is placed between the two movable plates 21, the two movable plates 21 are driven to approach until the two arc-shaped clamping plates 24 clamp both ends of the LNG gas tank inner liner. Then, the heat insulation belt wound on the winding drum 32 is led out and bonded to the LNG gas tank inner liner. At this time, the first motor 23 is started to drive the clamped LNG gas tank inner liner to rotate, and then, in cooperation with the reciprocating motion of the rotating bracket 31, the winding drum 32 moves synchronously, so that the heat insulation belt can be evenly wound on the LNG gas tank inner liner. Therefore, only a narrow-width heat insulation belt is needed to complete the winding of the LNG gas tank inner liner, without preparing heat insulation belts of different widths, reducing the cost.

[0029] The clamping mechanism 2 further includes a slide rail 25, which is fixedly installed on the top of the base 1, and a slide block 26 is slidably installed inside, and a lead screw 27 is rotatably installed. The number of the slide blocks 26 is two, and they are respectively fixedly connected to the two movable plates 21. The lead screw 27 is threadedly connected to the two slide blocks 26 in opposite directions, and a second motor 28 is assembled at one end.

[0030] In this embodiment, after the second motor 28 is started, the lead screw 27 can be driven to rotate, so as to drive the two slide blocks 26 to slide relatively in the slide rail 25, and the two movable plates 21 move relatively synchronously.

[0031] The reciprocating mechanism 3 further includes a guide slide bar 33, the extending direction of the guide slide bar 33 is the same as that of the slide rail 25, and it is fixedly connected to the top of the base 1 through a support rod 34. A slide plate 35 is slidably installed on the guide slide bar 33. The slide plate 35 is fixedly connected to the rotating bracket 31, and is hinged to a first connecting rod 36. The other end of the first connecting rod 36 is hinged to a connecting sleeve 37. The connecting sleeve 37 is arranged on a second connecting rod 38. A third motor 39 is assembled at one end of the second connecting rod 38.

[0032] In this embodiment, after the third motor 39 is started, it can drive the second connecting rod 38 to rotate. The connecting sleeve 37 rotates synchronously to make the first connecting rod 36 swing reciprocally, so as to pull the sliding plate 35 to slide reciprocally on the guide rod 33, and the rotating bracket 31 moves reciprocally synchronously.

[0033] The connecting sleeve 37 is slidably sleeved on the second connecting rod 38, and a threaded hole 371 is formed through one side thereof, and a positioning bolt 340 is assembled in the threaded hole 371.

[0034] In this embodiment, after the connecting sleeve 37 slides on the second connecting rod 38, it can be locked at different positions through the threaded hole 371, and then the connection relationship with the first connecting rod 36 can be changed, so as to adjust the amplitude of its driven reciprocal swing, and finally make the reciprocal distance of the winding drum 32 adjustable, so that the inner liner of the LNG gas tank with different widths can be wound, and there is no need to replace the winding drum 32, reducing the labor intensity and improving the production efficiency at the same time.

[0035] A placing table 4 is arranged between the two movable plates 21. A V-shaped limiting groove 41 is formed at the top of the placing table 4, and the bottom is connected to the top of the base 1 through an electric telescopic rod 5.

[0036] In this embodiment, after the inner liner of the LNG gas tank is placed on the top of the placing table 4, it can be limited by the V-shaped limiting groove 41 and driven to lift by the electric telescopic rod 5, so as to facilitate the clamping mechanism 2 to clamp.

[0037] The above embodiments only represent a certain implementation manner of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.

[0038] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art.
