Description

Technical Field

[0001] This invention belongs to the field of aerospace production technology, specifically relating to a universal storage tank lifting and tilting device and assembly method. Background Technology

[0002] The current mainstream solution for lifting and tilting storage tanks involves using a gantry crane to transport the tanks to the designated tilting position, then using two sets of lifting equipment to lift the tanks simultaneously from both ends. The tilting is achieved by coordinating the lifting heights of the two sets of lifting equipment. However, this method offers poor protection for the storage tanks, requires highly skilled operators, and makes it difficult to guarantee tilting stability. Therefore, it is not a safe and reliable solution.

[0003] Patent document CN215160229U discloses a lifting device, comprising: a first lifting beam with a first sling extending downward; a second lifting beam with a second sling extending downward, the second sling being shorter than the first sling; a hook disposed on the first lifting beam; an adjusting device disposed between the first and second lifting beams to adjust the distance between the first and second lifting beams; a first connecting member detachably disposed on the first sling and connected to a first end of the object to be lifted; and a second connecting member detachably disposed on the second sling and connected to a second end opposite to the first end of the object to be lifted.

[0004] Although patent document CN215160229U solves the problem of the complexity of the existing process for turning over large items to be lifted, its turning stability is poor. In particular, when dealing with storage tanks of different models and specifications, changes in their center of gravity and sling length will affect the lifting operation of the storage tanks, resulting in low equipment adaptability.

[0005] To meet the requirements for lifting and tilting multiple models and batches of storage tanks, a lifting and tilting platform that is compatible with various models and can ensure stable operation is needed. Therefore, this invention designs a universal storage tank lifting and tilting device, solving the aforementioned problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a universal storage tank lifting and tilting device and assembly method.

[0007] A universal storage tank lifting and tilting device according to the present invention includes: a tilting frame, a front connecting ring, a rear connecting ring, and a lifting beam assembly;

[0008] The tilting trolley includes the trolley body, trolley suspension, guide rails, storage tank bracket, tilting platform, vertical limit mechanism, damping guide wheel and movable tilting platform;

[0009] The chassis itself serves as the basic platform;

[0010] The frame suspension is located below the frame body, supporting the frame body to move on the ground;

[0014] The guide rail is laid on the frame body, and its two ends correspond to the storage tank bracket and the tipping platform. The tipping platform is equipped with guide wheels that slide along the guide rail.

[0015] A guide rail is formed on the side of the vertical limiting mechanism;

[0016] Damping guide wheels are installed on both sides of the tilting platform. The damping guide wheels cooperate with the side guide rails of the vertical limit mechanism to limit the tilting platform in the vertical direction.

[0017] The movable tilting platform is installed on the tilting platform, and the installation position is adjustable according to the size of the storage tank;

[0018] The lifting beam assembly is installed on the front connecting ring and the storage tank is lifted.

[0019] Preferably, the vehicle suspension includes a spring damping mechanism and a leaf spring damping mechanism;

[0020] The spring damping mechanisms are respectively installed at both ends of the vehicle suspension and are equipped with a steering mechanism to provide overall steering and damping for the vehicle.

[0021] The leaf spring damping mechanism is located in the middle of the vehicle frame suspension to dampen the overall vibration of the vehicle frame.

[0022] Preferably, the tilting platform is equipped with a locking mechanism, which can lock the tilting platform to the frame body during storage tank transportation.

[0023] Preferably, the front connecting ring includes a front connecting ring body, a first flipping bracket, and a hoisting limiter;

Detailed Implementation

[0052] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0053] like Figure 1-8 As shown, a universal storage tank lifting and tilting device includes: a tilting frame 1, a front connecting ring 2, a rear connecting ring 3, and a lifting beam assembly 4;

[0054] The tilting trolley 1 includes: trolley body 1-1, trolley suspension 1-2, guide rail 1-3, storage box bracket 1-4, tilting platform 1-5, vertical limiting mechanism 1-6, damping guide wheel 1-7, and movable tilting platform 1-8;

[0055] The frame body 1-1 serves as the basic platform for frame integration;

[0056] The frame suspension 1-2 is integrated under the frame body, using leaf springs and spring shock absorption mechanism, and solid rubber wheels to bear the weight of the entire frame and storage box during transportation, while also taking into account steering and parking functions.

[0057] Preferably, the vehicle suspension 1-2 includes a spring damping mechanism and a leaf spring damping mechanism. The spring damping mechanism is located at both ends of the vehicle suspension 1-2 and is equipped with a steering mechanism, which can realize the overall steering of the vehicle and the damping effect during transportation.

[0058] The leaf spring damping mechanism is located in the middle of the frame suspension 1-2, which can realize the damping effect during the frame transportation process.

[0059] Guide rails 1-3 are laid on the frame body 1-1 to provide motion guidance for the tilting platform 1-5;

[0060] The storage tank bracket 1-4 is installed on the frame body 1-1 to support the rocket storage tank;

[0061] The tilting platform 1-5 is mounted on the guide rail 1-3 via the lower guide wheel, which is used to support the storage tank and slide on the guide rail 1-3 in conjunction with the lifting beam assembly 4 to realize the tilting function of the storage tank;

[0062] The tilting platform 1-5 is equipped with a locking mechanism that can lock and fix it to the frame body 1-1 to prevent the storage box from moving back and forth due to inertia during transportation.

[0063] The vertical limiting mechanism 1-6 forms a guide rail on its side. The guide rail works with the damping guide wheel 1-7 on the side of the flipping platform 1-5 to limit the flipping platform 1-5 in the vertical direction and prevent the flipping platform 1-5 from getting off the guide rail 1-3 due to movement jamming.

[0064] The damping guide wheels 1-7 are spring-mounted on both sides of the tilting platform 1-5. The vertical limiting mechanism 1-6 gradually increases in height along the guide rail near the storage tank bracket 1-4, and the distance between the bearing surfaces of the guide rails on both sides gradually decreases on the horizontal plane.

[0065] When the storage tank is erected to a near-vertical position, the tilting platform 1-5 moves to a position close to the bracket under the action of the storage tank. The springs of the damping guide wheels 1-7 on both sides are compressed due to the reduced gap between the guide rails, which provides resistance for the tilting platform 1-5 to continue moving forward and prevents the tilting platform 1-5 from being jolted by the force of gravity when the storage tank enters the vertical position. This, together with the vertical limit mechanism 1-6, enables the tilting platform 1-5 to be tilted and provides a buffer for the impact generated during the erection of the storage tank.

[0066] The movable tilting platform 1-8 is installed on the tilting platform 1-5. By adjusting the installation position, it can adapt to the usage requirements of storage tanks with different diameters.

[0067] The front connecting ring 2 includes: a front connecting ring body 2-1, a first tilting bracket 2-2, and a hoisting limiter 2-3. The front connecting ring body 2-1 connects to the storage tank and also serves as an installation platform for the first tilting bracket 2-2 and the hoisting limiter 2-3; the first tilting bracket 2-2 is installed on the front connecting ring body 2-1 to connect the lifting beam assembly 4, enabling the storage tank to be erected and tilted during hoisting.

[0068] The hoisting limiter 2-3 is installed on the front connecting ring body 2-1 and extends along the direction of movement of the hoisting beam assembly 4 to the two sides of the tank. When the tank is in a horizontal state, the hoisting beam assembly 4 abuts against the hoisting limiter 2-3 on the side opposite to the tank. The hoisting limiter 2-3 protects the tank from colliding with the moving hoisting beam assembly 4.

[0069] The rear connecting ring 3 includes: a rear connecting ring body 3-1 and a second flipping bracket 3-2. The rear connecting ring body 3-1 connects to the storage tank and also serves as the mounting platform for the second flipping bracket 3-2. The second flipping bracket 3-2 is mounted on the rear connecting ring body 3-1 and is used to connect the flipping platform 1-5 to achieve the functions of fixing and flipping the storage tank. The mounting interface between the flipping platform 1-5 and the second flipping bracket 3-2 adopts a quick-release interface, allowing the flipping platform 1-5 to be quickly separated from the rear connecting ring 3.

[0070] The lifting beam assembly 4 includes a lifting beam 4-1 and steel cables 4-2. The lifting beam 4-1 is used to connect to the hook of equipment such as overhead cranes or truck cranes, and the storage tank is lifted by the traction movement of the lifting equipment. The lifting beam 4-1 is provided with multiple steel cable 4-2 installation interfaces to accommodate the lifting of storage tanks of different diameters. The steel cables 4-2 are used to connect the lifting beam 4-1 and the first tilting support 2-2. The steel cables 4-2 are fixed lengths calculated to constrain the movement radius of the lifting beam 4-1 relative to the first tilting support 2-2, ensuring that the lifting beam 4-1 can abut against the lifting limit 2-3 when the storage tank is in a horizontal state, ensuring that the storage tank and the lifting beam 4-1 do not interfere with each other, and preventing the lifting beam 4-1 from moving towards the storage tank during the lifting process and causing the storage tank to collide with the lifting beam 4-1.

[0071] Preferably, the requirements of storage tanks with different diameters can be met by adding adapter components corresponding to storage tanks of different sizes at the connection points between the front connecting ring 2 and the rear connecting ring 3 and the storage tank. Alternatively, the front connecting ring 2 and the rear connecting ring 3 with the appropriate diameter can be directly replaced to meet the requirements of storage tanks with different diameters.

[0072] This invention enables the transportation and tilting of various types of storage tanks. When lifting the storage tank, it can stably raise the storage tank from a horizontal position, avoiding the explosive impact during the lifting process. After the tank is raised, the tilting platform and the rear connecting ring are separated to achieve the overall lifting of the storage tank in a vertical position.

[0073] This embodiment also provides an assembly method for a universal tank lifting and tilting device, used for tank tilting and lifting, the steps of which include:

[0074] Step S1: The rocket tank transport tilting frame vehicle 1 carries the tank to the predetermined lifting position. The lifting equipment is connected to the lifting beam assembly 4. After the first tilting bracket 2-2 is connected with the steel cable 4-2, the tilting platform 1-5 is unlocked, and the lifting equipment begins to lift vertically.

[0075] Step S2: During the hoisting process, the front end of the storage tank rises with the lifting beam assembly 4, and the rear end of the storage tank moves along the guide rail 1-3 to the front end of the tilting frame vehicle 1 via the tilting platform 1-5 under the action of the hoisting force.

[0076] Step S3: After the storage tank moves to a vertical position, the tilting platform 1-5 is separated from the rear connecting ring 3 to complete the tilting operation, and further hoisting work can be carried out.
