Description

Vibration damper for marine transportation of superconducting magnet and superconducting magnet

Technical Field

The utility model belongs to the technical field of vibration reduction devices, and particularly relates to a vibration reduction device for marine transportation of a superconducting magnet and the superconducting magnet.

Background

The superconducting magnet, as a high-precision medical instrument part, has strict requirements on transportation conditions, and according to the IMDG rule, a movable tank cabinet for carrying class 2 frozen liquefied gas should be able to bear the operation direction during design and manufacture: twice the total mass times the acceleration due to gravity; the vertical direction of the running direction: twice the total mass times the acceleration due to gravity; the gravity direction is as follows: twice the total mass (including the total load due to gravity) times the acceleration due to gravity. In a marine transportation environment, the vibration and the impact of the ship are influenced by the combined action of various factors such as weather, stormy waves, navigational speed, load and load conditions and the like, the randomness of the vibration and the impact is high, and the random combination ensures that the impact acceleration of the ship is random and irregular. Obviously, higher shock accelerations mean higher risks, and therefore the transportation reliability can only be improved by reducing the shock accelerations of the marine transportation of the superconducting magnet as much as possible.

The existing superconducting magnet transportation device consists of an inner frame, an outer frame and a housing frame. The inner frame is arranged in the outer frame and is connected with the outer frame through an elastic vibration damping device, and the elastic vibration damping device is composed of a plurality of damping springs and a damping air bag. When the damping device is used, the superconducting magnet is placed in the damping device, then the shell frame is covered, and the damping spring and the damping air bag have damping and buffering effects on the superconducting magnet. However, this device requires a volume to accommodate the superconducting magnet and is not suitable for installation inside a container. In addition, the whole device adopts a steel frame structure, and a plurality of damping springs and damping air bags are arranged, so that the manufacturing cost is high; in many times, the device needs to be recycled, and the return transportation cost is brought; when assembling the superconducting magnet and the vibration reduction device, the superconducting magnet needs to be lifted by the height of at least one main body, the assembling process is complicated, and the operation difficulty is high.

The core of the utility model is to provide the vibration damper for marine transportation of the superconducting magnet and the superconducting magnet, and the vibration damper has the advantages of simple structure, small occupied space and low manufacturing cost.

In order to make those skilled in the art better understand the technical solutions provided by the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 in combination with fig. 2 and 3, the present solution provides a vibration damping device for marine transportation of superconducting magnets, including: a housing 1 and a cushioning member 3.

The buffer member 3 is disposed in an inner cavity of the housing 1, the housing 1 is used for providing a supporting position for an underframe of the superconducting magnet 6, and the buffer member 3 is used for buffering vibration received by the superconducting magnet 6. The housing 1 may be designed to just accommodate the under-frame of the superconducting magnet 6, or may be designed to be slightly larger than the under-frame size of the superconducting magnet 6 to leave an assembly margin.

The shell 1 can be made of metal materials, and can be made of other materials, sizes and shapes, and the shell with the functions is within the protection range of the scheme.

For the vibration damper that needs to hold whole superconducting magnet among the prior art, the vibration damper that this scheme provided has the die cavity that the shell encloses, arranges the bolster 3 that has certain thickness in the die cavity, and bolster 3 can form certain buffering holding surface to superconducting magnet 6. The vibration reduction device is positioned between the superconducting magnet and the floor of the container and used for buffering vibration and impact transmitted to the superconducting magnet by the container. The vibration damper has the advantages of simple structure, small occupied space and low manufacturing cost, can be loaded into a container along with the superconducting magnet 6, and is suitable for shipping container transportation.

In this embodiment, a plurality of buffer units may be provided for each damping device, that is, a plurality of buffer members 3 may be provided at intervals in the inner cavity of the housing 1, and the plurality of buffer members 3 may form a certain supporting surface for the superconducting magnet 6. The spacing space between adjacent buffers 3 can provide an avoidance position for the buffers deformed by force. Each buffer member 3 is fixed to the housing 1 by the partition plate 2, so that the plurality of buffer members 3 are distributed in the space formed by the housing 1. A spacing space formed between the partition plate 2 and the housing 1 can accommodate the buffer member 3 made of a shock-absorbing material while allowing elastic deformation of the buffer member 3.

In order to ensure that the supporting legs of the superconducting magnet 6 are always in contact with the damping material, the height of the damping piece 3 in a stressed state and an unstressed state is not lower than that of the partition board 2. Preferably, the buffer 3 may be a cushion or a shock-absorbing spring. The cushion pad is an elastic material with a certain thickness, the cross section area, the material property and the thickness of the cushion pad are important parameters influencing the cushioning performance of the cushion pad, the required vibration reduction performance is achieved by the design and combination of the three parameters, and a rubber pad or a spongy cushion can be specifically adopted.

As shown in fig. 3, the base frame 601 of the superconducting magnet 6 has four supporting legs, and each superconducting magnet 6 is correspondingly provided with 4 vibration reduction devices. The base frame 601 is placed on the upper surface of the cushion pad 3. When the superconducting magnet works, the superconducting magnet 6 exerts a downward acting force on the cushion pad 3 under the action of self gravity and impact acceleration, and due to the characteristics of the material, the cushion pad 3 deforms, the height is reduced, and the sectional area is increased, as shown in fig. 2. When the external force is removed, the cushion pad 3 restores the original state, and the process is repeated in this way, so that the superconducting magnet 6 is buffered.

In a further embodiment, the vibration damping device further comprises a positioning pin 4 for rotatably connecting the housing 1 and the base frame 601, so as to mount the vibration damping device on the base frame 601 of the superconducting magnet 6 through the positioning pin 4. Specifically, through holes are formed in two sides of the housing 1, and correspondingly, the chassis 601 is provided with the same through holes. During installation, the vibration damping device is installed on the underframe 601 of the superconducting magnet 6, and then the positioning pin 4 is inserted into the through holes corresponding to the vibration damping device and the superconducting magnet 6, so that the vibration damping device and the superconducting magnet 6 can be fixed, and quick assembly and disassembly can be realized.

In order to prevent the positioning pin 4 from coming off from the vibration damping device and the superconducting magnet 6, limiting members 5, specifically, snap springs or limiting pins, may be disposed at two ends of the positioning pin 4.

The damping device of the scheme has small volume, can be installed on the magnet and is loaded into a container along with the magnet, and is suitable for shipping container transportation; the damping performance is remarkable, the marine transportation impact of the superconducting magnet can be reduced to a required range, different damping requirements can be met by selecting different buffer designs, and the adaptability is strong; the structure is simple, the assembly and disassembly are convenient, the manufacturing cost is low, and the disposable medical infusion bag can be used for one time.
