[0027] Reference Figure 1-4 As shown, this embodiment discloses a protective frame for a liquid nitrogen storage tank, including a base 1, a support plate 2 is fixedly connected to the upper surface of the base 1, a protective frame 3 is slidably connected to the surface of the support plate 2, a fixing device 4 is provided on the upper surface of the base 1, and an auxiliary device 5 is provided on one side of the base 1.
[0028] Reference Figure 1-4As shown, the fixing device 4 includes two brackets 41, which are fixedly connected to the upper surface of the base 1. The two brackets 41 are centrally symmetrical. A screw 42 is threadedly connected to the surface of the bracket 41. One end of the screw 42 is rotatably connected to a splint 43. Two symmetrical limit plates 44 are fixedly connected to both sides of the splint 43, and the two limit plates 44 are inclined. When the storage tank 6 needs to be protected, the staff first moves the protective frame 3 and moves the protective frame 3 to the top of the support plate 2. At this time, the storage tank 6 is placed above the base 1 and the protective frame 3 is moved to the storage tank 6, thereby achieving the effect of preliminarily fixing the storage tank 6. At this time, the staff rotates the screw 42 on the bracket 41, and the screw 42 moves with the splint 43 and the limit plate 44. Finally, the two splints 43 squeeze the storage tank 6, thereby achieving the effect of fixing the storage tank 6, and the two limit plates 44 are located on both sides of the storage tank 6 to prevent the storage tank 6 from sliding. The fixing device 4 achieves the effect of fixing storage tanks 6 of different sizes, preventing the storage tank 6 from shaking on the base 1, thereby causing the storage tank 6 to tip over.
[0029] Reference Figure 1-4 As shown, one end of the screw 42 is fixedly connected to a handle 45, and one side of the handle 45 is fixedly connected to two protrusions. By providing the handle 45, the contact area between the staff's hand and the screw 42 is increased, thereby facilitating the staff to rotate the screw 42, which brings convenience to the staff. The surface of the bracket 41 slides through a limit rod 46, and one end of the limit rod 46 is fixedly connected to the splint 43. By providing the limit rod 46, the effect of limiting the moving direction of the splint 43 is achieved, thereby preventing the splint 43 from rotating and improving the stability of the movement of the splint 43. One side of the limit plate 44 is fixedly connected to a plurality of rubber pads 47, and the plurality of rubber pads 47 are linearly distributed. By providing the rubber pads 47, the friction between the limit plate 44 and the storage tank 6 is increased to prevent the storage tank 6 from rotating.
[0030] Reference Figure 1-4 As shown, the auxiliary device 5 includes a guide plate 51, which is arranged on one side of the base 1. The cross-section of the guide plate 51 is triangular. A slide plate 52 is fixedly connected to one side of the guide plate 51. A chute 53 is provided at the base 1 corresponding to the slide plate 52. The slide plate 52 slides and fits in the chute 53. When the storage tank 6 needs to be moved to the base 1, the staff first inserts the slide plate 52 on one side of the guide plate 51 into the chute 53 of the base 1. At this time, the staff places the storage tank 6 on the inclined surface of the guide plate 51 and pushes the storage tank 6 onto the base 1 through the inclined surface of the guide plate 51. The auxiliary device 5 makes it easy for the staff to move the storage tank 6 above the base 1, and there is no need for the staff to lift the storage tank 6, which brings convenience to the staff.
[0031] Reference Figure 1-4As shown, the guide plate 51 has grooves on its inclined surface, which allow it to be rotatably connected to a number of rotating rods 54. By arranging the rotating rods 54 to rotate with the bottom of the storage tank 6, friction between the storage tank 6 and the guide plate 51 is reduced, providing convenience for personnel. A placement slot 55 is defined on one side of the base 1, and its dimensions are compatible with those of the guide plate 51. When the guide plate 51 is not in use, personnel insert a movable plate into the placement slot 55, effectively concealing the guide plate 51.
[0032] Working principle: When the storage tank 6 needs to be protected, the staff first moves the protective frame 3 and moves the protective frame 3 to the top of the support plate 2. At this time, the storage tank 6 is placed above the base 1, and the protective frame 3 is moved to the storage tank 6, thereby achieving the effect of preliminarily fixing the storage tank 6. At this time, the staff rotates the screw 42 on the bracket 41 through the handle 45, and the screw 42 moves with the splint 43 and the limit plate 44. Finally, the two splints 43 squeeze the storage tank 6, thereby achieving the effect of fixing the storage tank 6, and the two limit plates 44 are located on both sides of the storage tank 6 to prevent the storage tank 6 from sliding. The fixing device 4 achieves the effect of fixing storage tanks 6 of different sizes, preventing the storage tank 6 from shaking on the base 1, thereby causing the storage tank 6 to tip over.
[0033] When the storage tank 6 needs to be moved to the base 1, the staff first inserts the slide plate 52 on one side of the guide plate 51 into the slide groove 53 of the base 1. At this time, the staff places the storage tank 6 on the inclined surface of the guide plate 51, and the storage tank 6 and the rotating rod 54 rotate to reduce the friction between the storage tank 6 and the inclined surface of the guide plate 51, making it convenient for the staff to push the storage tank 6 to the top of the base 1 through the inclined surface of the guide plate 51. When the guide plate 51 is not needed, the staff inserts the movable plate into the placement groove 55 to achieve the effect of hiding the guide plate 51. The auxiliary device 5 is used to facilitate the staff to move the storage tank 6 above the base 1, and the staff does not need to lift the storage tank 6, which brings convenience to the staff.
