Description

Technical Field

[0001] The invention belongs to an auxiliary device for transporting a superconducting magnetic resonance device, and more specifically, relates to a device for transporting and fixing a superconducting magnet for magnetic resonance imaging. Background Art

[0002] At present, during the hoisting and transportation of superconducting magnetic resonance devices, it is inevitable that bumps, impacts, etc. occur, which will cause vibrations and impacts to the superconducting magnetic resonance devices. Existing magnetic resonance devices are divided into various types. According to the different properties of the magnets used, MRI is usually divided into three types: permanent magnet type MRI, normal conduction type MRI, and superconducting type MRI. Especially for superconducting type MRI, after its superconducting magnet undergoes large vibrations and / or impacts, it is very likely that the superconducting magnet will lose superconductivity during the excitation process at the installation site. Therefore, there is an urgent need for a transporting and fixing device to ensure that the superconducting magnetic resonance device will not be affected by factors such as vibrations and impacts during transportation. Summary of the Invention

[0003] The invention provides a device for transporting and fixing a superconducting magnet for magnetic resonance imaging, which is used to avoid the superconducting magnetic resonance device from being affected by factors such as vibrations and impacts during transportation, prevent the superconducting magnetic resonance device from malfunctioning, and improve the earthquake resistance and impact resistance of the superconducting magnetic resonance device during hoisting.

[0004] To achieve the above object, the technical solution adopted by the invention is as follows:

[0005] A device for transporting and fixing a superconducting magnet for magnetic resonance imaging includes an inner fixing mechanism disposed inside a support cylinder of the superconducting magnetic resonance device. The inner fixing mechanism has an inner expansion airbag, and the inner expansion airbag is inflated and expanded against the inner wall of the support cylinder. End fixing mechanisms are respectively connected to both ends of the inner fixing mechanism. The two end fixing mechanisms are respectively buckled to the axial two ends of the superconducting magnetic resonance device, and each end fixing mechanism has an end expansion airbag, and the end expansion airbag is inflated and expanded against the end of the superconducting magnetic resonance device.

[0006] Further, the inner fixing mechanism includes a support mechanism disposed inside the inner expansion airbag, and both ends of the support mechanism are respectively connected to the two end fixing mechanisms.

[0007] Further, after being inflated, the inner expansion airbag is in a cylindrical structure, the support mechanism is disposed inside the cylindrical structure, and the support mechanism is connected to the inner wall of the cylindrical structure.

[0008] Further, the support mechanism includes an adjustment rod disposed inside the inner inflation airbag and coinciding with its axis. A plurality of ridges are evenly arranged on the inner wall of the inner inflation airbag along its circumferential direction. Each ridge extends axially from one end of the inner inflation airbag to the other end. Each ridge has an assembly hole extending from one end to the other end. A support rod is assembled in each assembly hole. At least two adjustment sleeves are threadedly connected to the adjustment rod. A plurality of connecting rods are hinged at intervals along the circumferential direction of each adjustment sleeve. One end of each connecting rod away from the adjustment sleeve is hinged to the corresponding support rod through a notch on the ridge. Both ends of the adjustment rod and each support rod are connected to two end fixing mechanisms.

[0009] Further, the end fixing mechanism includes an end fixing plate. A buckle edge is formed on the edge of the end fixing plate. The end inflation airbag is disposed at one end of the end fixing plate close to the superconducting magnetic resonance device, and a circumferential covering airbag communicating with it is formed on the outer periphery of the end inflation airbag. A suspension ring and a fixing seat are respectively constructed at the upper and lower ends of the end fixing plate.

[0010] Further, a plurality of connecting plates arranged in a radiation shape are constructed in the middle of the end fixing plate, and one end of each connecting plate is close to each other and connected to the central position of the end fixing plate. A strip-shaped hole is formed along the length direction of each connecting plate. The end of the inner fixing mechanism extends out of the strip-shaped hole on the connecting plate and is connected to the end fixing plate.

[0011] Further, a plurality of first self-detaching suction cups and a plurality of second self-detaching suction cups are respectively arranged on the surfaces of the inner inflation airbag and the end inflation airbag corresponding to the superconducting magnetic resonance device, and both the first self-detaching suction cups and the second self-detaching suction cups are adsorbed on the corresponding surfaces of the superconducting magnetic resonance device.

[0012] Further, the first self-detaching suction cup and the second self-detaching suction cup have the same structure. Both of them include a suction cup body and a connecting body constructed at the center of the suction cup body. The connecting body and the suction cup body are of an integrally formed structure. One end of the connecting body away from the suction cup body is connected to the corresponding surface of the inner inflation airbag or the end inflation airbag. The connecting body has a hollow ventilation cavity, and the ventilation cavity communicates with the suction cup body. A plurality of ventilation holes are constructed on the connecting body, and the ventilation holes communicate the ventilation cavity with the outside.

[0013] Further, one end of the connecting body away from the suction cup body is threadedly connected to the corresponding surface of the inner inflation airbag or the end inflation airbag.

[0014] Further, the connecting body and the suction cup body have the same shape, and the small-diameter end of the connecting body is connected to the small-diameter end of the suction cup body.

[0015] Due to the adoption of the above structure, the technical progress achieved by the present invention compared with the prior art lies in: by placing the internal fixing mechanism inside the support cylinder of the superconducting magnetic resonance device and inflating the inner tightening airbag, the outer wall of the inner tightening airbag is tightened against the inner wall of the support cylinder. Then, the two end fixing mechanisms are respectively assembled with both ends of the superconducting magnetic resonance device, and each end fixing mechanism is connected to the corresponding end of the internal fixing mechanism. After that, the end tightening airbag of the end fixing mechanism is inflated, so that the outer wall of the end tightening airbag is tightened against the corresponding end face of the superconducting magnetic resonance device. In this way, during the hoisting and transportation process, the components subjected to vibration and / or impact are the end fixing mechanisms. Since the inner tightening airbag and the end tightening airbag have the functions of buffering and energy absorption, it avoids the direct hard contact between the superconducting magnetic resonance device and external objects, thereby avoiding the superconducting magnetic resonance device from bearing vibration and / or impact force. Moreover, because the internal fixing mechanism and the end fixing mechanism are connected together and form an integral body, when the integral body is subjected to external force, the internal fixing mechanism and the end fixing mechanism act on each other and gradually offset the absorbed energy, effectively ensuring the safety of the superconducting magnetic resonance device. To sum up, the present invention avoids the influence of factors such as vibration and impact on the superconducting magnetic resonance device during transportation, prevents the superconducting magnetic resonance device from malfunctioning, and at the same time improves the seismic and anti-impact capabilities of the superconducting magnetic resonance device during hoisting.

Detailed implementation manners

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0032] The present invention discloses a transportation and fixing device for a superconducting magnet of magnetic resonance imaging, as Figure 1 - Figure 2As shown in the figure, it includes an internal fixing mechanism 200 and two end fixing mechanisms 100. Among them, the internal fixing mechanism 200 is arranged inside the support cylinder of the superconducting magnetic resonance device. The hollow part of the support cylinder of the present invention is the space where the body part to be detected is located. The internal fixing mechanism 200 of the present invention has an internal inflation airbag 201, and the internal inflation airbag 201 is inflated and tightened on the inner wall of the support cylinder. The above two end fixing mechanisms 100 are respectively connected to both ends of the internal fixing mechanism 200. At this time, the superconducting magnetic resonance device is located between the two end fixing mechanisms 100. These two end fixing mechanisms 100 are respectively buckled at the axial two ends of the superconducting magnetic resonance device. Each end fixing mechanism 100 has an end inflation airbag 107, and the end inflation airbag 107 is inflated and tightened on the corresponding end of the superconducting magnetic resonance device. The working principle and advantages of the present invention: The present invention places the internal fixing mechanism 200 inside the support cylinder of the superconducting magnetic resonance device and inflates the internal inflation airbag 201, so that the outer wall of the internal inflation airbag 201 is tightened on the inner wall of the support cylinder. Then, the two end fixing mechanisms 100 are respectively assembled with both ends of the superconducting magnetic resonance device, and each end fixing mechanism 100 is connected to the corresponding end of the internal fixing mechanism 200. Then, the end inflation airbag 107 of the end fixing mechanism 100 is inflated, so that the outer wall of the end inflation airbag 107 is tightened on the corresponding end face of the superconducting magnetic resonance device; in this way, during the hoisting and transportation process, the components affected by vibration and / or impact are the end fixing mechanisms 100. Since the internal inflation airbag 201 and the end inflation airbag 107 have the functions of buffering and energy absorption, it avoids the direct hard contact between the superconducting magnetic resonance device and external objects, and thus avoids the superconducting magnetic resonance device from bearing vibration and / or impact force. Moreover, since the internal fixing mechanism 200 and the end fixing mechanism 100 are connected together and form an integral body, when the integral body is subjected to external force, the internal fixing mechanism 200 and the end fixing mechanism 100 act on each other and gradually offset the absorbed energy, effectively ensuring the safety of the superconducting magnetic resonance device; in summary, the present invention avoids the superconducting magnetic resonance device from being affected by factors such as vibration and impact during transportation, prevents the superconducting magnetic resonance device from malfunctioning, and at the same time improves the earthquake resistance and impact resistance of the superconducting magnetic resonance device during hoisting.

[0033] As a preferred embodiment of the present invention, as Figure 2 - Figure 3As shown, the end fixing mechanism 100 includes an end fixing plate 101 and the above-mentioned end expansion airbag 107. Among them, a buckle edge 102 is formed on the edge of the end fixing plate 101. The end expansion airbag 107 is arranged at one end of the end fixing plate 101 close to the superconducting magnetic resonance device. Moreover, a peripheral edge covering airbag 108 is formed on the outer peripheral edge of the end expansion airbag 107. The peripheral edge covering airbag 108 is communicated with the end expansion airbag 107. A first inflation nozzle 110 communicated with the end expansion airbag 107 is constructed on the end fixing plate 101. Through the first inflation nozzle 110, the end expansion airbag 107 and the peripheral edge covering airbag 108 are inflated synchronously, so that the end expansion airbag 107 is tightened on the end face of the superconducting magnetic resonance device, and the peripheral edge covering airbag 108 is covered on the peripheral surface of the end of the superconducting magnetic resonance device. In this embodiment, in order to facilitate the hoisting of the superconducting magnetic resonance device, a lifting ring 106 is fixed at the upper end of each end fixing plate 101, and the hoisting device hoists the fixed superconducting magnetic resonance device through a steel wire rope; in this embodiment, in order to facilitate the fixation with the transfer vehicle, a fixing seat 103 is constructed at the lower end of the end fixing plate 101, and the fixing seat 103 is connected to the corresponding bearing surface of the transfer vehicle through a fixing bolt.

[0034] As a preferred embodiment of the present invention, in order to prevent the inner expansion airbag 201, the end expansion airbag 107 and the peripheral edge covering airbag 108 from moving relative to each other after tightening the corresponding surfaces of the superconducting magnetic resonance device, effectively improve the integrity of the connection between the inner expansion airbag 201, the end expansion airbag 107 and the peripheral edge covering airbag 108 and the superconducting magnetic resonance device, and further improve the stability of the superconducting magnetic resonance device after being fixed, as Figure 4 , Figure 9 shown, a plurality of first self-detaching suction cups 205 are arranged on the surface of the inner expansion airbag 201 corresponding to the superconducting magnetic resonance device, and a plurality of second self-detaching suction cups 109 are arranged on the surfaces of the end expansion airbag 107 and the peripheral edge covering airbag 108 corresponding to the superconducting magnetic resonance device, and both the first self-detaching suction cups 205 and the second self-detaching suction cups 109 are adsorbed on the corresponding surface of the superconducting magnetic resonance device. Among them, as Figure 5As shown, the first self - detaching suction cup 205 and the second self - detaching suction cup 109 have the same structure. Both of them include a suction cup body 1091 and a connecting body 1092. The connecting body 1092 is constructed at the center of the suction cup body 1091. The connecting body 1092 and the suction cup body 1091 are of an integrally formed structure. Moreover, one end of the connecting body 1092 away from the suction cup body 1091 is connected to the corresponding surface of the inner expansion airbag 201, or the end expansion airbag 107, or the peripheral covering airbag 108. The connecting body 1092 of this embodiment has a hollow ventilation cavity, which is in communication with the suction cup body 1091. A plurality of ventilation holes 1093 are constructed on the connecting body 1092, and these ventilation holes 1093 communicate the ventilation cavity with the outside. The working principles of the first self - detaching suction cup 205 and the second self - detaching suction cup 109 in this embodiment are the same. Taking the second self - detaching suction cup 109 as an example in this embodiment: When the inner expansion airbag 201 is inflated and gradually expands until the suction cup body 1091 of the second self - detaching suction cup 109 contacts the corresponding surface of the superconducting magnetic resonance device, as the inner expansion airbag 201 continues to expand, the gas in the suction cup body 1091 and the connecting body 1092 is squeezed out through the ventilation holes 1093. When the gas is completely discharged, the suction cup body 1091 firmly adheres to the surface of the superconducting magnetic resonance device. And at this time, the inner expansion airbag 201 expands and undergoes a certain deformation, thereby closing the connection between the connecting body 1092 and the outside, so that the suction cup body 1091 and the inner expansion airbag 201 cooperate to prevent the superconducting magnetic resonance device from being displaced or moving relatively. When it is necessary to release the adsorption and fixation of the second self - detaching suction cup 109 on the superconducting magnetic resonance device, the inner expansion airbag 201 is deflated, so that the inner expansion airbag 201 gradually becomes smaller. When the ventilation holes 1093 of the connecting body 1092 are in communication with the outside, the outside gas enters the suction cup body 1091 through the ventilation holes 1093 and the ventilation cavity of the connecting body 1092. A positive pressure appears in the suction cup body 1091, and the suction cup body 1091 releases the adsorption and fixation on the superconducting magnetic resonance device, realizing the self - detaching function. In this embodiment, in order to facilitate the replacement of different models of the first self - detaching suction cup 205 and / or the second self - detaching suction cup 109, as Figure 7 shown, one end of the connecting body 1092 away from the suction cup body 1091 is threadedly connected to the corresponding surface of the inner expansion airbag 201, or the end expansion airbag 107, or the peripheral covering airbag 108. In this embodiment, in order to facilitate the exhaust of the ventilation cavity and the suction cup body 1091, and at the same time facilitate the full closure of the ventilation holes 1093, as Figure 6As shown, the connecting body 1092 has the same shape as the suction cup body 1091, and the small-diameter end of the connecting body 1092 is connected to the small-diameter end of the suction cup body 1091. When the inner expansion airbag 201 or the end expansion airbag 107 is inflated and the suction cup body 1091 contacts and is deformed under pressure by the superconducting magnetic resonance device, the connecting body 1092 and the suction cup body 1091 discharge gas. The outer surface of the suction cup body 1091 contacts the outer surface of the connecting body 1092 and closes the ventilation hole 1093. When the inner expansion airbag 201 or the end expansion airbag 107 deflates, the outer surface of the suction cup body 1091 separates from the outer surface of the connecting body 1092, the ventilation hole 1093 is exposed, and the ventilation cavity gradually inhales air through the ventilation hole 1093, realizing the separation of the suction cup body 1091 from the surface of the superconducting magnetic resonance device. In this embodiment, both the suction cup body 1091 and the connecting body 1092 are structures made of silica gel material.

[0035] As a preferred embodiment of the present invention, as Figure 8 - Figure 12 shown, the inner fixing mechanism 200 includes a support mechanism and the above-mentioned inner expansion airbag 201. Among them, the support mechanism is arranged inside the inner expansion airbag 201, and a second inflation nozzle 211 is constructed on one side of the inner expansion airbag 201. In this embodiment, both ends of the support mechanism are respectively connected to the end fixing plates 101 of the two end fixing mechanisms 100. Among them, after the inner expansion airbag 201 is inflated, it is a cylindrical structure, the support mechanism is arranged inside the cylindrical structure, and the support mechanism is connected to the inner wall of the cylindrical structure. In this embodiment, the shape of the inner expansion airbag 201 is changed through the support mechanism, and thus support cylinders with different diameters are realized. The specific structure of the support mechanism of the present invention is, as Figure 10 shown, the support mechanism includes an adjustment rod 207, a plurality of support rods 206 and a plurality of connecting rods 208. Among them, the adjustment rod 207 is arranged inside the inner expansion airbag 201, and the axis of the adjustment rod 207 coincides with the axis of the inner expansion airbag 201. In this embodiment, a plurality of convex strips 202 are evenly arranged on the inner wall of the inner expansion airbag 201 along its circumferential direction. Each convex strip 202 extends axially from one end of the inner expansion airbag 201 to the other end, and each convex strip 202 has an assembly hole 203 extending from one end to the other end. Each support rod 206 of this embodiment is assembled in the corresponding assembly hole 203. At least two adjustment sleeves 209 are threadedly connected to the adjustment rod 207. The above-mentioned plurality of connecting rods 208 are divided into two groups, and the two groups of connecting rods 208 are respectively installed on the two adjustment sleeves 209. Each group of connecting rods 208 is evenly arranged along the circumferential direction of the adjustment sleeve 209. Among them, one end of the connecting rod 208 is hinged to the circumferential surface of the adjustment sleeve 209, and the end of the connecting rod 208 far from the adjustment sleeve 209 is hinged to the corresponding support rod 206 through the notch 204 on the convex strip 202. In this embodiment, the positions between the support rods 206 are adjusted so that the inner expansion airbag 201 changes from Figure 11The shown form changes into Figure 12 the shown form, or changes from Figure 12 the shown form into Figure 11 the shown form, which is achieved by rotating the adjusting rod 207. Specifically, a handwheel 210 is detachably installed at one end of the adjusting rod 207. By rotating the handwheel 210, the adjusting rod 207 rotates self - sufficiently, thereby enabling the two adjusting sleeves 209 to approach or move away from each other, and further enabling the support rods 206 to gather or move away from each other, causing the shape of the inner expansion airbag 201 to change to adapt to support cylinders of different diameters. In this embodiment, both ends of the adjusting rod 207 and each support rod 206 are connected to two end fixing mechanisms 100. Specifically, a plurality of connecting plates 104 arranged in a radial form are constructed in the middle of the end fixing plate 101, and one ends of the connecting plates 104 approach each other and are connected to the central position of the end fixing plate 101. A strip - shaped hole 105 is formed along the length direction of each connecting plate 104. The end of the adjusting rod 207 passes through the central position of the end fixing plate 101, and the end of each support rod 206 extends out of the corresponding connecting plate 104 through the strip - shaped hole 105, and a fastening nut is threadedly connected to the end of the support rod 206. The fastening nut is tightened on the end face of the connecting plate 104, thus ensuring that the end fixing mechanism 100 and the inner fixing mechanism 200 are connected as a whole.

[0036] As a preferred embodiment of the present invention, ribs are provided in the inflation cavity of the inner expansion airbag 201 at the position of the support rod 206. The ribs extend axially to both ends of the inner expansion airbag 201, connecting the circumferential walls at the corresponding positions of the inner expansion airbag 201. And in order to ensure that the inflation cavity is not blocked by the ribs, there are air vents on the ribs for communicating the inflation cavity. In this embodiment, to reduce the production and processing difficulty, generally, the inner layer and the outer layer of the inner expansion airbag 201 at the position of the support rod 206 are hot - melt vulcanized together at multiple points, that is, at the position of the inner expansion airbag 201 corresponding to the support rod 206, a plurality of fixing points are formed at intervals along the length direction of the support rod 206. Each fixing point is a point where the inner layer and the outer layer of the inner expansion airbag 201 are connected to each other. In this way, when the support rods 206 gather or move away from each other under the drive of the connecting rod 208, the inner expansion airbag 201 at the position of the support rod 206 bulges or contracts along the radial direction of the inner expansion airbag 201.

[0037] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
