Description

Technical Field

[0001] The utility model belongs to the technical field of cultural relics protection, and specifically refers to a museum cultural relics transportation device. Background Art

[0002] Museums are the guardians of human civilization and history. The cultural relics in their collections carry rich historical information and cultural value, and are precious heritage that is non-renewable and irreplaceable. The protection of museum cultural relics is of vital importance, and the transportation of cultural relics is a key link in the protection of cultural relics, and its safety is directly related to the integrity of cultural relics.

[0003] During the transportation process, cultural relics are prone to damage, deformation and other problems due to environmental changes, vibration and impact. The traditional method of transporting cultural relics mainly relies on wooden boxes, foam and other materials for packaging and protection. However, this traditional transportation method has many shortcomings.

[0004] The traditional packaging principle mainly relies on fillers to fix and cushion cultural relics. A large number of studies have shown that the main reason for the damage of cultural relics during transportation is not continuous shaking, but intermittent collisions with packaging materials during shaking. Due to the different shapes and sizes of cultural relics, it is difficult for fillers to fit completely with the surface of cultural relics. Even tiny gaps may be magnified due to the resonance effect during transportation, resulting in violent collisions and friction between the cultural relics and the packaging materials, causing irreversible damage such as wear, scratches, and even breakage on the surface of the cultural relics.

[0005] In order to minimize vibration and impact during transportation, traditional cultural relics packaging often adopts a multi-layer structure and uses a large amount of filling materials such as foam, sponge, cotton, etc. The packaging process is complicated and cumbersome, consuming a lot of manpower and time. At the same time, the cumbersome packaging also increases transportation and storage costs. Utility Model Content

[0035] Among them, the protective power mechanism 5 includes a fixing member 51 and a third support rod 57. The fixing member 51 is fixed on the outside of the third movable plate 33. A hollow disk 52 is fixed at one end of the fixing member 51. A turntable 53 is coaxially and tightly arranged inside the hollow disk 52.

A torque overload protector 55 is coaxially fixed at the other end of the screw 54. A rocker 56 is engaged and inserted at one end of the torque overload protector 55.

[0036] Among them, the adaptive filling and stabilizing mechanism 6 includes a first magnetic fluid cover 61, a second magnetic fluid cover 62 and an electromagnet 63. The first magnetic fluid cover 61 is fixedly arranged at the middle inner side of the first movable plate 31, the second movable plate 32, the third movable plate 33 and the fourth movable plate 34, and the second magnetic fluid cover 62 is fixedly arranged at the middle lower side of the cover plate 35. The electromagnet 63 penetrates and is embedded in the first movable plate 31, the second movable plate 32, the third movable plate 33, the fourth movable plate 34 and the cover plate 35. The first magnetic fluid cover 61 and the second magnetic fluid cover 62 are filled with magnetic fluid. The first magnetic fluid cover 61 and the second magnetic fluid cover 62 are made of flexible material. One end of the cover plate 35 and the upper part of the baffle 311 are jointly provided with a matching lock buckle 8, and the driving power supply 7 drives all electromagnets 63 to start at the same time.

[0037] Among them, when the deformable protective shell 3 is in the initial state, the second movable plate 32 is tightly attached to the inner side of the baffle 311, when the second movable plate 32 is tightly attached to the inner side of the baffle 311, the first pressure spring 46 is in the maximum compression state and the second pressure spring 48 is in the natural state, and the electromagnet 63 is always located on the side wall of the space formed after the deformable protective shell 3 is contracted.

[0038] During specific use, ensure that the deformable protective shell 3 is at the maximum expansion degree, which is the initial state. At this time, the second movable plate 32 is tightly attached to the inner side of the baffle 311, and then one end of the third movable plate 33 presses against the edge of the second movable plate 32, so that the first pressure spring 46 is compressed to the maximum extent, and one end of the fourth movable plate 34 contacts the edge of the third movable plate 33, and the second pressure spring 48 is naturally unstressed. At this time, ensure that the knob 421 is in a loosened state, and then put the cultural relic into the deformable protective shell 3, and the cultural relic is close to the fourth movable plate 34 and the first movable plate 31, and then cover the cover 35, which is propped up by the baffle 311 and locked and fixed by the lock buckle 8, and then start to turn the rocker 56, drives the screw rod 54 to rotate. Since the third support rod 57 is fixed, the screw rod 54 moves forward. Due to the positional relationship between the turntable 53 and the hollow disk 52, the turntable 53 pushes the third movable plate 33 forward, and moves forward at a 45-degree angle, so that the third movable plate 33 moves toward the first movable plate 31 and the fourth movable plate 34 at the same speed, so that the fourth movable plate 34 is resisted and begins to overcome the pressure of the second pressure spring 48 and moves toward the second guide tube 44, so that the second movable plate 32 is not bound by the third movable plate 33 and is pushed toward the fourth movable plate 34 by the first pressure spring 46. At this time, due to the contraction of the deformation protection shell, the first magnetic fluid cover 61 and the second magnetic fluid cover 62 are moved by the first movable plate 31, The second movable plate 32, the third movable plate 33 and the fourth movable plate 34 are in contact and squeezed in the contraction direction. The existence of the first pressure spring 46 and the second pressure spring 48 prevents the first magnetic fluid cover 61 on the second movable plate 32 and the third movable plate 33 from being tightly compressed, but can have a certain elastic change to avoid being crushed. At this time, there is a gap between the lower side of the cover plate 35 and the upper ends of the second movable plate 32, the third movable plate 33 and the fourth movable plate 34, and there is a gap between the end of the second movable plate 32 facing the inner side of the first movable plate 31 and the first movable plate 31, and there is a gap between the inner side of the fourth movable plate 34 and the first movable plate 31 facing the inner side, so that the second magnetic fluid cover 62 and the first magnetic fluid cover 61 on the first movable plate 31 and the fourth movable plate 34 The cover 61 is not tightly squeezed and damaged. When the first magnetic fluid cover 61 and the second magnetic fluid cover 62 are squeezed toward the fourth movable plate 34 and the first movable plate 31, the magnetic fluid in the first magnetic fluid cover 61 and the second magnetic fluid cover 62 is gathered and bulged to approach the cultural relics, so that the upper end and the side end of the cultural relics are wrapped by the magnetic fluid, and the liquid form of the magnetic fluid will fully fill all parts of the cultural relics. When it is wrapped to a certain extent, the torque of the screw 54 will be too large. At this time, the torque overload protector 55 will take effect, so that the rocker 56 and the torque overload protector 55 slip and no longer drive the screw 54, thereby preventing the cultural relics from being further squeezed and damaged. The torque overload protector 55 is an existing conventional technology and its structural principle will not be repeated.

[0039] Then, the electromagnet 63 is turned on by driving the power supply 7, and the electromagnet 63 generates a magnetic field, causing the magnetic fluid to undergo a phase change and become a quasi-solid state, thereby fully filling and fixing the cultural relics, and then tightening the knob 421 to fully fix the second movable plate 32 and the fourth movable plate 34, and then the transportation can begin. Since the magnetic fluid fully fills the contact parts of the cultural relics and then fixes them, no gaps will be generated, thereby avoiding the risk of damage to the cultural relics during transportation. In addition, the shock-absorbing effect of the shock-absorbing roller 2 protects the safety of the cultural relics during transportation to the greatest extent.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
