Description

Device for weight reversal and stabilization

The invention relates to a device for turning and stabilizing a heavy object, in particular to a combination of self-rotating characteristics generated by applying an eccentric moment, in particular to a method for using a nuclear tank for dry storage. Type of container.

At present, the method for heavy object reversal uses a crane to directly lift and retract the weight itself or its auxiliary structural support frame. However, this method requires sufficient working space and equipment to cooperate. When the heavy object needs to be moved into a specific indoor place and then turned over, it is often limited by the load capacity of the fixed crane and the structure of the plant, or the net height under the hook. Inadequate or incapable of using mobile cranes due to limited working space, such passive flipping methods cannot be used. The existing automatic turning method adopts a powerful hydraulic mechanism to actively lift and control the heavy objects; however, this turning method requires a large power to drive the hydraulic mechanism, and the hydraulic mechanism fails. It is quite dangerous. Therefore, the general practitioners cannot meet the needs of the user in actual use.

The main object of the present invention is to overcome the above problems encountered in the prior art and to provide a self-rotating characteristic set by applying an eccentric moment, which is applicable to the use of a cylindrical shape in dry storage of used nuclear fuel. The device of the container.

A secondary object of the present invention is to provide a function for avoiding the inversion of heavy objects due to a plurality of environmentally limited conditions, and to achieve weight reversal through simple, reliable and labor-saving traction control, and at the same time Ensure that the weight is stable and safe before and after the rollover and reach the limit of overcoming the door height.

For the purpose of the above, the present invention is a device for turning and stabilizing a weight, which is formed by applying a self-rotating characteristic generated by an eccentric moment, and includes at least a seat frame and a support base combined with a weight. And a rotating support capable of inverting the weight and the frame, and a traction mechanism for controlling the weight and the flip angle of the frame, and a control for rotating the weight and the frame The lifting mechanism of the center height is used for safe transportation of heavy objects and related operations.

Referring to FIG. 1 to FIG. 3, respectively, a schematic front view of a preferred embodiment of the present invention, a schematic side view of a preferred embodiment of the present invention, and a preferred embodiment of the present invention The structure is a schematic view of the section. As shown in the figure: the present invention is a device for reversing and stabilizing a weight, and the device 1 is formed by applying a self-rotating characteristic generated by an eccentric moment, and at least includes a frame 11 combined with a weight. The support base 12 and the rotating support 13 are combined with a traction mechanism 14, and may further include a jacking mechanism 15. It can be applied to containers with a cylindrical shape in the dry storage of used nuclear fuel, so as to safely carry out the transportation of the heavy objects and related operations.

The top of the frame 11 is a single-sided opening structure for lifting and unloading the weight on the frame 11, and then a strap or a steel strip is firmly coupled with the frame 11, wherein the frame 11 is fixedly coupled to the frame 11. The cross-section can be geometric.

The support base 12 is located at the bottom of the unitary device 1 to hold the frame 11 and the weight stable.

The rotating support 13 is located beside the center of gravity of the frame 11 and the weight assembly, so that the weight and the frame 11 have a rotating tendency opposite to the pulling direction. When the traction mechanism 14 is gradually released, Turning it up to its full erection, on the other hand, when the traction mechanism 14 is gradually tightened, it is returned to the state of lying down.

The position of the traction mechanism 14 is located at the near edge of the frame 11, and a large torque can be generated to control the angle of the flipping of the frame 11 and the weight.

The jacking mechanism 15 is a device for controlling the height of the center of rotation of the mount 11 and the support base 12 at the two ends of the pivot support 13 to enable the mount 11 and before and after the flipping The weight is lowered onto the support base 12 for stabilization, and the mount 11 and the weight can be lifted at an appropriate height for flipping when flipped. If so, a new device 1 for large weight reversal and stabilization is constructed by the above structure.

The manner in which the frame 11 and the weight are combined may be other types, and the weight is fixed and attached thereto. For example, if the weight itself has a rotational support, the frame 11 may be further omitted. And directly mounted on the jacking mechanism 15; the traction mechanism 14 can also be engaged with the mount 11 or the weight in various other manners, and can be a human or small power motor or any equivalent device; When the present invention omits the jacking mechanism 15, the purpose of inverting can also be achieved, and the weight can be fixed by the bottom stopper when lying or standing upright.

When the invention is used, the weight is hoisted and mounted on the frame 11, and is firmly coupled with the frame 11 by means of a belt or a steel belt; then, the device 1 is combined with the weight It is suspended and fixed on the transport vehicle, and the transport vehicle is transported to a designated location to be turned over. When the inversion is performed, the lifting mechanism 15 is used to lift up, and the traction mechanism 14 is gradually released, so that the weight will gradually be turned from the original lying state to the upright state; when the weight is completed, the top is up. The lifting mechanism 15 is shortened so that the weight is smoothly seated on the support base 12 together with the seat frame 11, thereby completing the turning of the weight.

When the weight is required to be leveled, the jacking mechanism 15 is lifted up, and the lifting mechanism 14 is gradually tightened, so that the weight will be gradually turned from the erect state to the lying state; when the weight is completed After lying flat, the jacking mechanism 15 is shortened, so that the weight is smoothly seated on the support base 12 together with the seat frame 11, thereby completing the lying level of the weight.

It can be seen from the above that the present invention utilizes the slight eccentricity of the center of gravity of the weight and the center of rotation, so that the weight itself has a tendency to rotate due to the eccentric moment, and traction control is performed at an appropriate position, since the traction control is required to be applied. The external force is quite small, and it is only necessary to overcome the eccentric moment of the heavy object. Therefore, a small traction and tightening device, such as an electric motor, can be used to save labor and control its automatic flipping; and, the utility can be used for lifting linear motion. The jacking mechanism can be used to reduce the height to a very low position when the heavy object is lying or erected, which can greatly improve the safety of heavy objects or personnel to be close to the operation, and can overcome most factories (indoor places) The height limit of the door allows the heavy object to sit on the flat when it is transported, or when it is turned upright, it can sit on the bottom smoothly and achieve a stable function by supporting the base.

In summary, the present invention is a device for reversing and stabilizing a weight, which can effectively improve various disadvantages of the prior art, can avoid the difficulty of heavy object inversion due to various environmentally limited conditions, and is simple, reliable, and labor-saving. The traction control can achieve the purpose of weight reversal, and at the same time, it can ensure the stability and safety of the weight before and after the turning and achieve the limitation of the door height, so that the invention can be more advanced, more practical and more consistent. The user must have met the requirements for the creation of a patent application and file a patent application in accordance with the law.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto; therefore, the simple equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the novel specification All should remain within the scope of the invention patent.
