Description

Technical Field

[0001] The utility model belongs to the technical field of object lifting, and relates to a tank lifting device. Background Art

[0002] Various tanks, such as reaction tanks, storage tanks, transport tanks, and assembly tanks, are used in industries such as chemical production, microbial fermentation, and pharmaceutical preparation. Reaction tanks and other tanks are large in size, and therefore require lifting or hoisting with instruments and equipment during installation and maintenance.

[0003] Currently, the lifting of large tanks typically involves fixing a circular tube to the tank base with expansion screws. An electric hoist is then suspended from the tube's upper end. This is controlled by a power distribution cabinet, which in turn controls the lifting of the fall chain using a pulley system, thereby raising and lowering the tank. However, the electric hoist requires a crane for suspension, which is labor-intensive and prone to damage to the gears and mounting surfaces of the hoist. Furthermore, when lifting large tanks, the electric hoist is subject to uneven force, creating the risk of tipping over. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please refer to the attached Figure 1 、 2 , attached Figure 1 、 2The top view and the front view of the tank lifting device provided by the embodiment of the present application are shown respectively. Figure 1 、 2 It can be seen that the tank lifting device provided in the embodiment of the present application includes a control cabinet 1, multiple hydraulic workstations 2 and multiple hydraulic cylinders 3.

[0022] The control cabinet 1 is electrically connected to multiple hydraulic workstations 2, each of which is also connected to multiple hydraulic cylinders 3 via oil pipes 10. This allows the control cabinet 1 to synchronize and control multiple hydraulic workstations 2, and thus multiple hydraulic cylinders 3, to operate synchronously, increasing synchronization stability and achieving more uniform stroke. The multiple hydraulic cylinders 3 are evenly distributed around the tank body 4, ensuring uniform force on the tank body and stable, synchronous lifting.

[0023] Two clamping plates 6 are arranged parallel to the top of the piston rod 5 of the hydraulic cylinder 3, and a hanging piece 7 is arranged on the outer surface of the tank body 4. The hanging piece 7 is movably clamped in the two clamping plates 6. Figure 3 As shown in the figure, when the tank 4 needs to be lifted, the two clamps 6 on the top of the piston rod 5 clamp the lifting fixture 7. The control cabinet 1 synchronizes and controls the operation of multiple hydraulic workstations 2, thereby controlling the operation of multiple hydraulic cylinders 3. At this time, the piston rods 5 of the hydraulic cylinders 3 extend, lifting the lifting fixture 7 on the tank 4, thereby lifting the tank 4.

[0024] In this embodiment of the present application, the hoisting member 7 includes a fixing plate 701 and a support plate 702. The fixing plate 701 is mounted on the outer wall of the tank body 4, and the support plate 702 is vertically fixed to the fixing plate 701. The support plate 702 is vertically movable and clamped between the two clamping plates 6 to achieve the connection between the hydraulic cylinder 3 and the tank body 4.

[0025] In order to prevent the lifting member 7 from falling off during the process of the piston rod 5 lifting the tank body 4, a first baffle 8 is further provided between the two clamping plates 6 in the embodiment of the present application. Figure 4 As shown in the figure, a U-shaped structure is formed between the two clamping plates 6 and the first baffle 8, with the U-shaped opening facing the tank body 4. When the hydraulic cylinder 3 is used to lift the tank body 4, the lifting member 7 is placed in the U-shaped structure formed by the two clamping plates 6 and the first baffle 8, forming a structural form that envelops the lifting member 7 and prevents it from falling out from between the two clamping plates 6.

[0026] To further prevent the hanging member 7 from falling off, a second baffle 9 is provided between the two clamping plates 6 in the embodiment of the present application. Figure 5 As shown, the two clamping plates 6, the first baffle 8, and the second baffle 9 form a frame structure. A certain distance exists between the lower end of the sling 7 and the tank body 4, forming a groove. As a result, the lower end of the sling 7 can be movably engaged within the frame structure formed by the two clamping plates 6, the first baffle 8, and the second baffle 9, further stabilizing the connection between the hydraulic cylinder 3 and the tank body 4 and preventing the sling 7 from falling out from between the two clamping plates 6.

[0027] In the tank lifting device provided in the embodiment of the present application, after the lifting member 7 is clamped between the two clamping plates 6, the control cabinet 1 is used to synchronously control the synchronous operation of multiple hydraulic workstations 2, thereby controlling the synchronous operation of multiple hydraulic cylinders 3. At this time, the piston rod 5 of the hydraulic cylinder 3 extends, lifting the lifting member 7 on the tank body 4, thereby lifting the tank body 4. The synchronous linkage control of multiple hydraulic cylinders 3 by the control cabinet 1 can increase the synchronization stability, make the stroke more uniform, and evenly apply force to each lifting point around the tank body 4, so that the tank body 4 can be stably and synchronously lifted. The tank lifting device provided in the embodiment of the present application is suitable for the installation and maintenance of various types of tanks.

[0028] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
