[0031] For example, Figures 1 to 6The safety protection device of the chemical storage tank shown comprises a protection vehicle frame 1, a hoisting mechanism 2, a protection cover plate 3 and a limiting buffer plate 4. The protection vehicle frame 1 comprises a mobile chassis 11, a push rod frame 12 vertically fixed to the mobile chassis 11 and a protection frame 13 connecting the mobile chassis 11 and the push rod frame 12. The mobile chassis 11 is in the shape of a concave character with one end open. The bottom of the mobile chassis 11 is provided with mobile wheels 111. The protection frame 13, the push rod frame 12 and the mobile chassis 11 enclose a hoisting space 14 for accommodating the chemical storage tank 5. The hoisting mechanism 2 is installed to the protection frame 13 and the mobile chassis 11. The hoisting mechanism 2 can hoist the chemical storage tank 5 in the hoisting space 14 to a set height, so as to facilitate the handling of the chemical storage tank 5. The protection cover plate 3 is buckled to the top opening of the chemical storage tank 5, so as to prevent the liquid in the chemical storage tank 5 from splashing out. The inner diameter of the protection cover plate 3 is greater than the outer diameter of the chemical storage tank 5. Rubber rings 31 are arranged at the inner side corners of the protection cover plate 3. The cross section of the rubber ring 31 is in the shape of a triangle. The outer periphery of the protection cover plate 3 is vertically downwardly provided with an extension cylinder 32. The limiting buffer plate 4 comprises a first arc-shaped plate 41, a second arc-shaped plate 42 and a spring 43 connecting the first arc-shaped plate 41 and the second arc-shaped plate 42. The first arc-shaped plate 41 is fixed to the mobile chassis 11. The second arc-shaped plate 42 abuts against the chemical storage tank 5, so as to buffer and protect the chemical storage tank 5 and improve the safety during the handling of the chemical storage tank 5.

[0032] In an embodiment, the protection vehicle frame 1 is manually pushed to the chemical storage tank 5, so that the chemical storage tank 5 is placed in the hoisting space 14. When the protection vehicle frame 1 is pushed, the second arc-shaped plate 42 of the limiting buffer plate 4 abuts against the outer wall of the chemical storage tank 5. The inner diameter of the second arc-shaped plate 42 is equal to the outer diameter of the chemical storage tank 5, so as to realize the preliminary positioning of the chemical storage tank 5 in the hoisting space 14. Since the spring 43 is arranged between the second arc-shaped plate 42 and the first arc-shaped plate 41, when the second arc-shaped plate 42 collides against the chemical storage tank 5, the spring 43 between the first arc-shaped plate 41 and the second arc-shaped plate 42 is compressed. The pushing force of the worker pushing the protection vehicle frame 1 is rapidly increased, so as to feed back to the worker that the chemical storage tank 5 is located at the set hoisting position in the hoisting space 14. The hook 21 of the hoisting mechanism 2 is manually hung to the lifting lug 51 of the chemical storage tank 5. Then, the pressing rod 24 is pressed down, so that the lifting rope 22 hoists the chemical storage tank 5 away from the ground by a set distance. The pressing rod 24 is clamped to the clamping hook 25, so that the chemical storage tank 5 in the hoisting space 14 is separated from the ground. The protection vehicle frame 1 protects the chemical storage tank 5 in three directions, so as to improve the completeness during the movement of the chemical storage tank 5.
