Description

Technical Field

[0001] The embodiments of the present application relate to the field of ray detector devices, and in particular to a ray detector moving device. Background Art

[0002] Radiation detectors are widely used in medical, industrial non-destructive testing and other fields. In practical applications, in order to minimize radiation hazards, radiation detectors need to be installed in special shielding bodies. The height of the radiation detector including the radiation detector shielding body needs to be adjusted according to the position of the radiation source, so that the center of the detector plate coincides with the center of the radiation source, so as to obtain ideal detector diagnostic results.

[0003] Therefore, a device is needed to adjust the three-dimensional movement of the radiation detector, so as to achieve the coincidence of the center of the detector plate and the center of the radiation source. In addition, since the total weight of the radiation detector and the detector shield is heavy, a special radiation detector moving device with strong load-bearing capacity, strong stability and good guidance is also needed. Summary of the invention

[0004] In view of this, an embodiment of the present application provides a radiation detector moving device, which can easily realize three-dimensional movement and adjustment of the radiation detector, and has the advantages of simple structure, good guidance and strong support.

[0005] In order to realize the above technical features, the embodiment of the present application provides a radiation detector moving device, including a base, a bracket and a guide assembly. Among them, the bracket is arranged on the base, used to support and fix the radiation detector, and the bracket can move vertically relative to the base. In addition, the guide assembly includes a guide column and a guide sleeve both extending in the vertical direction, the guide column is arranged on one of the base and the bracket, and the guide sleeve is arranged on the other of the base and the bracket, and both ends of the guide column extend out of the guide sleeve, and when the bracket moves vertically relative to the base, the guide sleeve slides along the guide column.

[0006] Specifically, the base is a plate-like structure and is arranged horizontally, the bracket is arranged vertically on the base, and can support and fix the radiation detector, and the bracket can be lifted and moved relative to the base in the vertical direction, so that the radiation detector fixed on the bracket can synchronously follow the bracket to be lifted and lowered relative to the base in the vertical direction. For the guide assembly, it includes a guide column and a guide sleeve both extending in the vertical direction, wherein when the guide column is arranged vertically on the base, correspondingly, the guide sleeve is arranged vertically on the outer wall of one side of the bracket close to the guide column, and both ends of the guide column extend out of the guide sleeve, so that when the bracket moves vertically relative to the base, the guide sleeve slides in the vertical direction along the guide column. Compared with the arrangement without the guide assembly, the existence of the guide assembly plays a guiding role when the bracket moves relative to the base, thereby enhancing the stability of the overall structure of the radiation detector moving device.

[0007] Here, it should be noted that the guide post is arranged on one of the base and the bracket, and the guide sleeve is arranged on the other of the base and the bracket, which specifically means: first, when the guide post is arranged on the base, the guide sleeve is arranged on the bracket accordingly. At this time, the guide post is vertically fixed on the base, the guide sleeve is vertically fixed on the bracket, and both ends of the guide post extend out of the guide sleeve. When the bracket moves vertically relative to the base, the guide sleeve slides along the guide post, and then when the bracket fixed with the guide sleeve moves vertically, the guide assembly composed of the guide post and the guide sleeve plays a guiding and supporting role in the vertical movement of the bracket relative to the base. Second, when the guide post is arranged on the bracket, the guide sleeve is arranged on the base accordingly, and both ends of the guide post extend out of the guide sleeve. When the bracket moves vertically relative to the base, the guide post slides along the guide sleeve. Similarly, it can achieve a guiding and supporting role in the vertical movement of the bracket.

[0008] In a possible implementation of the present application, the guide post is fixedly connected to the base, and the guide sleeve is fixedly connected to the bracket. When the bracket moves vertically relative to the base, the guide sleeve slides along the guide post, and then when the bracket fixed with the guide sleeve moves vertically, the guide assembly composed of the guide post and the guide sleeve plays a guiding and supporting role for the vertical movement of the bracket relative to the base. For example, when there are multiple guide sleeves corresponding to a guide post, the setting of the guide post being fixed to the base and the guide sleeve being fixed to the guide post makes the guiding and supporting properties of the bracket stronger.

[0009] In a possible implementation of the present application, there are multiple guide sleeves, and the multiple guide sleeves are distributed along the extension direction of the guide column. Compared with the design of only one guide sleeve, the design of multiple guide sleeves makes the sliding contact area between the guide column and the guide sleeve larger, thereby improving the guidance and support of the bracket.

[0010] In a possible implementation of the present application, there are multiple guide posts, and the multiple guide posts are arranged at intervals in the horizontal direction. Here, when there are multiple guide posts, the number of guide sleeves corresponding to each guide post can also be multiple, so that the multiple guide posts and the multiple guide sleeves are arranged one by one, further improving the guiding and supporting properties of the guide assembly for the bracket.

[0011] In a possible implementation of the present application, the guide assembly includes a reinforcement frame, the reinforcement frame is fixedly connected to the base, the reinforcement frame has a reinforcement portion extending in the vertical direction, and the guide column is fixed on the reinforcement portion. Compared with the design in which the lower end of the guide column is only fixedly connected to the base, this design can further increase the stability of the guide column when it is fixed on the base by setting the reinforcement frame to fix the guide column to the reinforcement portion of the reinforcement frame. In addition, since the weight of the radiation detector on the bracket is usually very large, further fixing the guide column on the reinforcement frame can ensure the stable support of the bracket by the guide assembly.

[0012] In a possible implementation of the present application, the guide post is fixed to the reinforcing part via a fastening structure, so that the guide post can be fixed to the reinforcing part more stably, thereby further improving the supporting effect of the guide assembly on the bracket.

[0013] Here, the structural form of the fastening structure is not limited, and the guide column only needs to be fastened and fixed on the reinforcement part. Preferably, the fastening structure can be a bolt connection. Compared with welding, the bolt connection is detachable and easy to operate.

[0014] In a possible implementation of the present application, there are multiple fastening structures, and the multiple fastening structures are arranged at both ends of the guide column. Here, the specific number of fastening structures is not limited. Preferably, a fastening structure is arranged at the upper end and the lower end of each guide column, so that not only can the fastening connection between the guide column and the reinforcement part be ensured, but the existence of the fastening structure can also play a limiting role on the guide assembly.

[0015] In a possible implementation of the present application, the reinforcement frame includes an upright side plate and a horizontal bottom plate, the reinforcement frame is fixedly connected to the base through the bottom plate, the reinforcement portion is the side plate close to the guide column, and the reinforcement frame has an opening on the side away from the guide column, and the opening is used to temporarily store items. With such a design, since the guide column is to be fixedly connected to the side plate of the reinforcement frame close to the guide column through a fastening structure, the side plate on the side close to the guide column is set as the reinforcement portion of the reinforcement structure, thereby strengthening the support for the guide column. In addition, the design of the reinforcement portion extending vertically downward can enable the reinforcement portion to support most of the guide column or the entire part of the guide column.

[0016] In a possible implementation of the present application, the radiation detector moving device includes a driving assembly, which is disposed on the base and is used to drive the bracket to move vertically relative to the base, thereby providing a driving force for the bracket to move relative to the base.

[0017] In a possible implementation of the present application, the driving assembly includes a driving member and a transmission member, one end of the transmission member is fixedly connected to the output shaft of the driving member, and the other end of the transmission member is transmission-connected to the bracket, and the driving assembly is used to drive the bracket to move in the vertical direction. Here, the driving member provides power for the vertical movement of the bracket relative to the base, wherein the driving form of the driving member can be hydraulic drive, pneumatic drive, motor, etc. In comparison, since it is easy to control the motor to make starting, acceleration, braking, reversal and other operating requirements, and it occupies a small space, the driving member of this embodiment adopts a motor. In addition, the motor here can be a single-output shaft motor or a dual-output shaft motor. In addition, the specific form of the driving assembly is not limited here, and it is sufficient to drive the bracket to move in the vertical direction through the transmission member.

[0018] In a possible implementation of the present application, the transmission member includes a transmission shaft and a screw rod, the transmission shaft is arranged in the horizontal direction, the screw rod is arranged in the vertical direction, and the transmission shaft and the screw rod are transmission-connected. With such a design, while the transmission shaft drives the screw rod to rotate in the horizontal plane, the bracket transmission-connected to the upper end of the screw rod can realize the lifting and lowering movement in the vertical direction of the screw rod, so as to achieve the effect of adjusting the height of the bracket.

[0019] In a possible implementation of the present application, a screw nut is sleeved on the upper end of the screw, the screw nut is fixed on the bracket, and the lower end of the screw is connected to the transmission shaft. Specifically, the lower end of the screw is connected to the transmission shaft, so that the screw can rotate relative to the screw nut fixed on the bracket, thereby realizing the height adjustment of the bracket.

[0020] In a possible implementation of the present application, one end of the transmission shaft is fixedly connected to the input shaft of the driving member, the other end of the transmission shaft is fixedly connected to the first bevel gear, the lower end of the screw is fixedly connected to the second bevel gear, and the first bevel gear is meshed with the second bevel gear. Here, the driving member drives the first bevel gear to rotate through the transmission shaft, and under the action of the gear transmission of the first bevel gear and the second bevel gear, the screw can rotate, and finally drives the bracket connected to it to make it move vertically. In addition, through the design of the meshing transmission of the first bevel gear and the second bevel gear, the rotation transmission of the screw is realized, making the transmission form simple and easy.

[0021] In a possible implementation of the present application, there are multiple screw rods and multiple transmission shafts, and the number of the multiple screw rods and the multiple transmission shafts is the same and they are arranged one by one. Such a design can further increase the stability of the bracket movement when the bracket height is adjusted, and improve the support of the bracket.

[0022] It should be noted that the arrangement of the plurality of screw rods and the plurality of transmission shafts being consistent in number and corresponding one to one specifically means that one end of each transmission shaft close to the lower end of the vertical screw rod is meshed with a vertical screw rod through a pair of bevel gears for transmission. Preferably, two screw rods and two transmission shafts can be used, and the lower end of each vertical screw rod is meshed with one end of each transmission shaft close to the screw rod through a pair of bevel gears for transmission. In addition, the two vertical screw rods are symmetrically arranged at the two ends of the bracket, and the two screw rods are limited by two screw nuts fixed on the bracket, and at the same time, the support capacity of the bracket is improved.

[0023] In a possible implementation of the present application, multiple transmission shafts are coaxially arranged on both sides of the driving member, and the multiple transmission shafts are synchronously linked. In this way, the synchronous transmission of the multiple transmission shafts can be ensured, thereby achieving stability when the bracket is raised or lowered.

[0024] In a possible implementation of the present application, the radiation detector moving device includes a control handle, which is electrically connected to the driving member and is used to control the driving member to make a corresponding response action. Here, the electrical connection can be a wireless connection or a wired connection, so that the operator can remotely control the driving member through the control handle. In addition, the response action can specifically refer to the start and stop of the driving member, acceleration, forward and reverse rotation of the output shaft of the driving member, etc.

[0025] In a possible implementation of the present application, a fixing plate is provided on the bracket, and at least two fixing plates are provided, and at least two fixing plates are respectively located on opposite sides of the radiation detector, and at least a portion of the fixing plate abuts against the outer wall of the radiation detector, so as to clamp the radiation detector between the fixing plates. The provision of at least two fixing plates can stably limit the radiation detector on the bracket to prevent the radiation detector from falling during the three-dimensional movement and adjustment process.

[0026] In a possible implementation of the present application, the radiation detector moving device further includes a plurality of rollers, and the plurality of rollers are fixedly mounted below the base. Thus, the arrangement of the plurality of rollers can facilitate the horizontal movement of the entire radiation detector moving device. Combined with the vertical lifting movement of the radiation detector, the radiation detector has thus achieved movement and adjustment in the entire three-dimensional direction.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0042] First of all, it should be noted that the radiation detector in the present application may refer to an X-ray detector, a gamma ray detector, etc., which is not limited here. In addition, the radiation detector includes a radiation detector shielding body to reduce the radiation radiation of the radiation detector. Here, the shape of the radiation detector shielding body is not limited. Preferably, it can be a box-shaped structure with a simple structure and easy processing. The material of the radiation detector shielding body can be tungsten alloy, lead, etc.

[0043] The present application embodiment provides a radiation detector moving device, referring to Figure 1 , Figure 2 and Figure 4 , including a base 1, a bracket 2 and a guide assembly 3. Among them, the bracket 2 is arranged on the base 1, and is used to support and fix the radiation detector 7, and the bracket 2 can move vertically relative to the base 1. In addition, the guide assembly 3 includes a guide column 31 and a guide sleeve 32 both extending in the vertical direction, the guide column 31 is arranged on one of the base 1 and the bracket 2, and the guide sleeve 32 is arranged on the other of the base 1 and the bracket 2. Both ends of the guide column 31 extend out of the guide sleeve 32. When the bracket 2 moves vertically relative to the base 1, the guide sleeve 32 slides along the guide column 31. The existence of the guide assembly 3, on the one hand, plays a guiding role when the bracket 2 moves relative to the base 1, and on the other hand, it also plays a certain supporting role for the bracket 2, thereby enhancing the stability of the overall structure of the radiation detector moving device.

[0044] Specifically, in some embodiments, referring to Figure 1 , Figure 2 and Figure 4The base 1 is a plate-like structure and is arranged horizontally. The bracket 2 is arranged vertically on the base 1, which can support and fix the radiation detector 7. The bracket 2 can be lifted and moved relative to the base 1 in the vertical direction. In this way, the radiation detector 7 fixed on the bracket 2 can synchronously follow the bracket 2 to be lifted and lowered relative to the base 1 in the vertical direction. In addition, the bracket 2 includes a support plate 21 and a support plate 22 fixedly connected to the bottom of the support plate. The support plate 21 is used to support and fix the radiation detector 7. Here, in order to enable the radiation detector 7 to move stably on the horizontal plane, the support plate 21 is arranged horizontally. Among them, the support plate 22 also includes an upright side plate extending downward along the lower surface of the support plate and a horizontal bottom plate fixedly connected to the lower surface of the support plate. The guide assembly 3 includes a guide column 31 and a guide sleeve 2 both extending in the vertical direction, wherein when the guide column 31 is vertically arranged on the base 1, the guide sleeve 32 is correspondingly vertically arranged on the outer wall of the bracket 2 close to the guide column 31. Specifically, the guide sleeve 32 can be fixedly arranged on the side plate of the support plate 22 close to the guide column 31 by fasteners, and both ends of the guide column 31 extend out of the guide sleeve 32. In this way, when the bracket 2 moves vertically relative to the base 1, the guide sleeve 32 slides in the vertical direction along the guide column 1. Compared with the absence of the guide assembly 3, the existence of the guide assembly 3 plays a guiding role in the movement of the bracket 2, thereby also improving the stability of the overall structure of the moving device of the radiation detector.

[0045] Here, it should be noted that the guide column 31 is arranged on one of the base 1 and the bracket 2, and the guide sleeve 32 is arranged on the other of the base 1 and the bracket 2. Specifically, it means: first, when the guide column 31 is arranged on the base 1, the guide sleeve 32 is correspondingly arranged on the bracket 2. At this time, the guide column 31 is vertically fixed on the base 1, the guide sleeve 32 is vertically fixed on the bracket 2, and both ends of the guide column 31 extend out of the guide sleeve 32. When the bracket 2 moves vertically relative to the base 1, the guide sleeve 32 slides along the guide column 31, and then when the bracket 2 fixed with the guide sleeve 32 moves vertically, the guide assembly 3 composed of the guide column 31 and the guide sleeve 32 plays a guiding and supporting role for the vertical movement of the bracket 2 relative to the base 1. Secondly, when the guide column 31 is set on the bracket 2, the guide sleeve 32 is correspondingly set on the base 1, and the two ends of the guide column 31 extend out of the guide sleeve 32. When the bracket 2 moves vertically relative to the base 1, the guide column 31 slides along the guide sleeve 32. Similarly, it can realize the guiding and supporting role for the vertical movement of the bracket 2.

[0046] In some embodiments, reference Figure 1 , Figure 2 and Figure 4The guide post 31 is fixedly connected to the base 1, and the guide sleeve 32 is fixedly connected to the bracket 2. When the bracket 2 moves vertically relative to the base 1, the guide sleeve 32 slides along the guide post 31, and then when the bracket 2 fixed with the guide sleeve 32 moves vertically, the guide assembly 3 composed of the guide post 31 and the guide sleeve 32 plays a guiding and supporting role for the vertical movement of the bracket 2 relative to the base 1. For example, when a plurality of guide sleeves 32 are corresponding to a guide post 31, the arrangement of the guide post 31 being fixed to the base and the guide sleeve 32 being fixed to the guide post 31 makes the guiding and supporting properties of the bracket 2 stronger.

[0047] Reference Figure 1 , Figure 2 and Figure 4 There are multiple guide sleeves 32, and the multiple guide sleeves 32 are distributed along the extension direction of the guide column 31. Compared with the design of only one guide sleeve 31, the design of multiple guide sleeves 32 makes the sliding contact area between the guide column 31 and the guide sleeve 32 larger, thereby improving the guiding and supporting performance of the bracket 2.

[0048] Continue, refer to Figure 1 , Figure 2 and Figure 4 There are multiple guide posts 31, and the multiple guide posts 31 are arranged at intervals in the horizontal direction. Here, when there are multiple guide posts 31, the number of guide sleeves corresponding to each guide post 31 can also be multiple, so that the multiple guide posts 31 are arranged one by one with the multiple guide sleeves 32, further improving the guiding and supporting properties of the guide assembly 3 to the bracket 2.

[0049] Specifically, in some embodiments, referring to Figure 1 , Figure 3 and Figure 4 There are two guide posts 31, which are arranged at intervals in the horizontal direction, and there are four guide sleeves 32, wherein a guide sleeve 32 is respectively arranged at the upper end and the lower end of each guide post 31. In this way, compared with only one guide sleeve 32 corresponding to one guide post 31, the arrangement of two guide sleeves 32 on one guide post 31 can increase the moving contact area between the guide post 31 and the guide sleeve 32, thereby improving the guiding, limiting and supporting performance of the bracket 2.

[0050] In some embodiments, reference Figure 3 , Figure 4 and Figure 5The guide assembly 3 includes a reinforcing frame 33, which is fixedly connected to the base 1. The reinforcing frame 33 has a reinforcing portion 331 extending in the vertical direction, and the guide column 31 is fixed on the reinforcing portion 331. Compared with the design in which the lower end of the guide column 31 is only fixedly connected to the base 1, this design can further increase the stability of the guide column 31 when it is fixed on the base 1 by setting the reinforcing frame 33 to fix the guide column 31 on the reinforcing portion 331. In addition, since the weight of the radiation detector 7 on the bracket 2 is usually very large, usually more than 600 kg, further fixing the guide column 31 on the reinforcing frame 33 can ensure that the guide assembly 3 can stably support the bracket 1.

[0051] In addition, refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The guide post 31 is fixed to the reinforcing portion 331 through the fastening structure 4. In this way, the guide post 31 can be fixed to the reinforcing portion 331 more stably, thereby further improving the supporting effect of the guide assembly 3 on the bracket 2.

[0052] Here, it should be noted that the structural form of the fastening structure 4 is not limited, and it is sufficient to fasten the guide column 31 to the reinforcing portion 331. Preferably, in some embodiments, refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The two ends of the fastening structure 4 have screw holes 41, and the guide column 41 can be fixedly connected to the reinforcing portion 331 by bolts and nuts. Compared with welding, the bolt and nut connection is a detachable connection, which is convenient for installation. In addition, the middle position of the fastening structure 4 has a limiting through hole 42, and the guide column 31 can pass through the limiting through hole 42. With such a fastening structure 4, the guide column 31 can be fixed on the reinforcing portion 331 more stably.

[0053] In some embodiments, reference Figure 1 , Figure 3 , Figure 4 and Figure 6 There are multiple fastening structures 4, and multiple fastening structures 4 are arranged at both ends of the guide column 31. Here, the specific number of the fastening structures 4 is not limited. Preferably, a fastening structure 4 is respectively arranged at the upper end and the lower end of each guide column 31, so that not only can the fastening connection between the guide column 31 and the reinforcing part 331 be ensured, but the existence of the fastening structure 4 can also play a role in limiting the guide assembly 3.

[0054] In some embodiments, reference Figure 1 , Figure 3 , Figure 4 and Figure 5The reinforcing frame 33 includes an upright side plate 333 and a horizontal bottom plate 332. The reinforcing frame 33 is fixedly connected to the base 1 through the bottom plate 332. The reinforcing portion 331 is a side plate close to the guide column 31. The side of the reinforcing frame 33 away from the guide column 31 has an opening, and the opening is used to temporarily store items. In addition, a horizontal reinforcing rod 334 is also provided between the two side plates 333 on the reinforcing frame 33 away from the guide column 31. The two ends of the reinforcing rod 334 are respectively fixedly connected to the inner walls of the two side plates 333 on the reinforcing frame 33 away from the guide column 31, so as to further improve the stability of the reinforcing frame 33. In the above design, since the guide column 31 is fixedly connected to the side plate 333 of the reinforcing frame 33 close to the guide column 31 through the fastening structure 4, the side plate on the side close to the guide column 31 is set as the reinforcing portion 331 of the reinforcing frame 33, thereby strengthening the support for the guide column 31. In addition, the design of the reinforcement portion 331 extending vertically downward can enable the reinforcement portion 331 to support most of the guide column 31 or the entire portion of the guide column 31 .

[0055] Reference Figure 1 , Figure 4 and Figure 7 The radiation detector moving device includes a driving assembly 5, which is arranged on the base 1 and is used to drive the bracket 2 to move vertically relative to the base 1. In this way, a driving force can be provided for the movement of the bracket 2 relative to the base 1.

[0056] Further, refer to Figure 1 , Figure 4 and Figure 7 The driving assembly 5 includes a driving member 51 and a transmission member 52. The driving member 51 is arranged on the base 1. One end of the transmission member 52 is fixedly connected to the output shaft of the driving member 51, and the other end of the transmission member 52 is transmission-connected to the bracket 2. The driving assembly 5 is used to drive the bracket 2 to move in the vertical direction. Here, the driving member 51 provides power for the vertical movement of the bracket 2 relative to the base 1. The driving form of the driving member 51 can be hydraulic drive, pneumatic drive, motor, etc. In comparison, since it is easy to control the motor to make running requirements such as starting, acceleration, braking, and reversing, and the motor occupies a small space, the driving member 51 of this embodiment adopts a motor. In addition, the motor here can be a single-output shaft motor or a dual-output shaft motor. In addition, the specific form of the driving assembly 5 is not limited here, and it is sufficient to drive the bracket 2 to move in the vertical direction through the transmission member 52.

[0057] Furthermore, refer to Figure 1 , Figure 4 and Figure 7The transmission member 52 includes a transmission shaft 521 and a screw rod 522. The transmission shaft 521 is arranged in the horizontal direction, and the screw rod 522 is arranged in the vertical direction. The transmission shaft 521 and the screw rod 522 are in transmission connection. With such a design, while the transmission shaft 521 drives the screw rod 522 to rotate in the horizontal plane, the bracket 2 which is in transmission connection with the upper end of the screw rod 522 can realize the lifting movement along the vertical direction of the screw rod 522, so as to achieve the effect of adjusting the height of the bracket 2.

[0058] Reference Figure 1 , Figure 4 and Figure 7 The upper end of the screw rod 522 is sleeved with a screw nut 6, which is fixed on the bracket 2, and the lower end of the screw rod 522 is in driving connection with the transmission shaft 521. Specifically, the lower end of the screw rod 522 is in driving connection with the transmission shaft 521, so that the screw rod 522 can rotate relative to the screw nut 6 fixed on the bracket 2, thereby realizing the height adjustment of the bracket 2.

[0059] In some embodiments, reference Figure 1 , Figure 4 and Figure 7 One end of the transmission shaft 521 is fixedly connected to the input shaft of the driving member 52, the other end of the transmission shaft 521 is fixedly connected to the first bevel gear 5211, the lower end of the screw rod 522 is fixedly connected to the second bevel gear 5221, and the first bevel gear 5211 is meshed with the second bevel gear 5221. Here, the driving member 52 drives the first bevel gear 5211 to rotate through the transmission shaft 521, and under the action of the gear transmission of the first bevel gear 5211 and the second bevel gear 5221, the screw rod 522 can rotate, and finally drives the bracket 2 connected thereto to move vertically. In addition, through the design of the meshing transmission of the first bevel gear 5211 and the second bevel gear 5221, the rotation transmission of the screw rod 522 is realized, making the transmission form simple and easy.

[0060] In some embodiments, reference Figure 1 , Figure 4 and Figure 7 There are multiple screw rods 522 and multiple transmission shafts 521, and the number of multiple screw rods 522 and multiple transmission shafts 521 is the same and they are arranged one by one. Such a design can further increase the stability of the movement of the bracket 2 when the height of the bracket 2 is adjusted, and improve the support of the bracket 2.

[0061] It should be noted that the arrangement of the plurality of screw rods 522 and the plurality of transmission shafts 521 being consistent in number and corresponding one to one specifically means that one end of each transmission shaft 521 close to the lower end of the vertical screw rod 522 is meshed with a vertical screw rod 522 through a pair of bevel gears for transmission. Preferably, two screw rods 522 and two transmission shafts 521 can be used, and the lower end of each vertical screw rod 522 is meshed with one end of each transmission shaft 521 close to the screw rod 522 through a pair of bevel gears for transmission. In addition, the two vertical screw rods 522 are symmetrically arranged at the two ends of the bracket 2, and the two screw rods 522 are limited by two screw nuts 6 fixed on the bracket 2, and at the same time, the support capacity of the bracket 2 is also improved.

[0062] In some embodiments, reference Figure 1 , Figure 4 and Figure 7 , multiple transmission shafts 521 are coaxially arranged on both sides of the driving member 52, and the multiple transmission shafts 521 are synchronously linked. In this way, the synchronous transmission of the multiple transmission shafts 521 can be ensured, thereby achieving stability when the bracket 2 is raised or lowered.

[0063] It should be noted that, here, the driving member 52 may also adopt a dual-output shaft motor. For example, when there are two transmission shafts 521, when a dual-output shaft motor is adopted, the output shafts on both sides of the motor are each fastened to a transmission shaft 521, so that the synchronous rotation of the two transmission shafts 521 can be achieved. If a single-output shaft motor is adopted, when there are two transmission shafts 521, two single-output shaft motors are required to cooperate with each other, so compared with a single-output shaft motor, its transmission efficiency is high and the structure is compact.

[0064] In some embodiments, reference Figure 2 and Figure 4 The radiation detector moving device includes a control handle, which is electrically connected to the driving member 52 and is used to control the driving member 52 to make a corresponding response action. Here, the electrical connection can be a wireless connection or a wired connection, so that the operator can remotely control the driving member 52 through the control handle. In addition, the response action can specifically refer to the start and stop of the driving member 52, acceleration, forward and reverse rotation of the output shaft of the driving member 52, etc.

[0065] In some embodiments, reference Figure 2 and Figure 4 The bracket 2 is provided with a fixing plate 9, at least two fixing plates 9, and at least two fixing plates 9 are respectively located on opposite sides of the radiation detector 7, and at least a part of the fixing plate 4 abuts against the outer wall of the radiation detector 7, so as to clamp the radiation detector 7 between the fixing plates 4. The provision of at least two fixing plates 4 can realize the stable limitation of the radiation detector 7 on the bracket 2, so as to prevent the radiation detector 7 from falling during the three-dimensional movement and adjustment process.

[0066] Here, the structural form of the fixing plate 9 is not limited. Preferably, refer to Figure 4 The fixing plate 9 is made of angle steel, which has low cost and strong applicability. Specifically, the fixing plate 9 is fastened to the upper surface of the support plate 21 of the bracket 2 by fasteners, and the fastening connection method can be screw connection, welding, etc., which is not limited here.

[0067] In some embodiments, reference Figure 1 and Figure 4 The radiation detector moving device also includes a plurality of rollers 8, and the plurality of rollers 8 are fixedly mounted below the base 1. Thus, the arrangement of the plurality of rollers 8 can facilitate the horizontal movement of the entire radiation detector moving device. Combined with the vertical lifting movement of the radiation detector 7, the radiation detector 7 has achieved the movement adjustment in the entire three-dimensional direction, so that the detector plate center and the radiation source center can be coincident through the three-dimensional movement adjustment.

[0068] It should be noted that the specific number of rollers 8 is not limited here. Preferably, the number of rollers 8 is four. In this way, compared with the design with less than four rollers 8, the support of the base 1 is better, and compared with the design with more than four rollers 8, the cost can be saved. In addition, the multiple rollers 8 are all universal wheels with a self-locking function. In this way, while facilitating movement, they also have a positioning function, thereby increasing the applicability of the mobile device for the radiation detector.
