Description

Technical Field

[0001] This utility model relates to the field of aluminum foil winding technology, specifically to an inner aluminum foil winding fixture. Background Technology

[0002] A liquid nitrogen tank is a device used for storing and transporting liquid nitrogen. Depending on its purpose and design, liquid nitrogen tanks can be divided into liquid nitrogen storage tanks and liquid nitrogen transport tanks. Storage tanks are mainly used for indoor static storage of liquid nitrogen and are not suitable for long-distance transportation while in operation.

[0003] Currently, liquid nitrogen tanks require aluminum foil to be wrapped around their inner liner during the production process for insulation. This is usually done using a fully automated wrapping mechanism, but the mechanism is complex, occupies a large area, and the equipment is expensive, inconvenient to maintain and operate.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0026] Reference Figures 1-4 As shown, an inner aluminum foil winding fixture includes:

[0027] Two movable frames 1, one movable frame 1 is rotatably equipped with a first positioning rod 2, and a turntable 4 is provided at one end of the first positioning rod 2. The other movable frame 1 is rotatably equipped with a second positioning rod 3, which is used to clamp the inner liner of the liquid nitrogen tank. Then, when winding, the inner liner can be rotated through the turntable 4. The structure is simple and the operation is convenient.

[0028] The crossbeam 6 is connected to two movable frames 1 via a connecting rod 5, and a base 51 is provided at the bottom of the connecting rod 5;

[0029] The telescopic mechanism is located between the connecting rod 5 and the movable frame 1, and is used to adjust the distance between the two movable frames 1 to facilitate clamping the inner liner of the liquid nitrogen tank;

[0030] Two brackets 7 are slidably mounted on the crossbeam 6 to support the inner liner of the liquid nitrogen tank. They can be placed using a gantry crane or operated using a forklift. Initially, the inner liners of the two liquid nitrogen tanks can be placed on the two brackets 7. First, aluminum foil is wrapped around the first inner liner. After wrapping, the other bracket 7 can be directly replaced to wrap the aluminum foil. The first inner liner can be replaced during this time, saving time and improving efficiency.

[0031] In one embodiment, the movable frame 1 includes a support base 11, with a universal wheel 12 rotatably mounted at the bottom of the support base 11 and a fixed pivot 13 mounted at the top of the support base 11. The first positioning rod 2 and the second positioning rod 3 are rotatably connected to the support base 11 through the fixed pivot 13.

[0032] The movable frame 1 facilitates movement and securely clamps the inner liner of the liquid nitrogen tank.

[0033] In one embodiment, a fixed rod 14 is provided on one side of the support base 11, and the telescopic mechanism includes a sleeve plate 15 fixed on the fixed rod 14, a connecting rod 5 inserted into the sleeve plate 15, a locking hole 16 is provided on the side wall of the sleeve plate 15, a locking rod 17 is inserted into the locking hole 16, and the connecting rod 5 is fixedly connected to the sleeve plate 15 through the locking rod 17.

[0034] When the inner liner is placed between the two positioning rods, the movable frames 1 on both sides move inward to fix the positioning rods to the inner liner. Then, the locking rod 17 can be screwed inward to fix the connecting rod 5 to the movable frame 1.

[0035] In one embodiment, the bracket 7 includes a hydraulic rod 71 slidably connected to the crossbeam 6, the top end of the hydraulic rod 71 is provided with a support plate 72 for lifting the liquid nitrogen tank, and the support plate 72 is provided with a clamping assembly.

[0036] The height of the inner liner can be adjusted by the hydraulic rod 71, and the clamping assembly is also for better fixing the inner liner of the liquid nitrogen tank. Initially, the hydraulic rod 71 is located at the lower end, which is convenient for placing the inner liner and also for facilitating the winding of aluminum foil. When the inner liner is moved between the two positioning rods, it is raised upwards so that the center of the inner liner is aligned with the positioning rods for easy clamping.

[0037] In one embodiment, the clamping assembly includes a bidirectional threaded rod 721 rotatably disposed within a support plate 72, clamping plates 722 disposed at both ends of the bidirectional threaded rod 721, and a limiting slider 723 sleeved on the bidirectional threaded rod 721 disposed at the bottom end of the clamping plate 722.

[0038] After placing the inner liner on the tray 72, the two clamping plates 722 are moved inward by rotating the bidirectional threaded rod 721 to fix and hold the inner liner in place, thus completing the initial fixation and preventing the inner liner from shaking during installation.

[0039] In one embodiment, a lead screw 61 is rotatably installed inside the crossbeam 6, and a movable slider 73 sleeved on the lead screw 61 is provided at the bottom end of the hydraulic rod 71. The two hydraulic rods 71 ​​are connected by a fixing frame 8.

[0040] The two brackets 7 move synchronously, and the fixed bracket 8 ensures that the distance between the two brackets 7 remains consistent. The lead screw 61 further ensures that the amount of movement of the two brackets 7 is the same.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
