Description

Technical Field

[0001] At least one embodiment of the present disclosure relates to static computed tomography equipment, and more specifically, to a radiation source mechanism and static computed tomography equipment.

Background Art

[0002] Due to the optical path arrangement, the detector mechanism of static computed tomography equipment (static CT) is often installed between the radiation source mechanism and the channel. When the detector mechanism needs to be replaced or maintained, due to the shielding by the radiation source mechanism, it is impossible to directly contact the detector mechanism from the outside. Therefore, after removing the radiation source mechanism and completing the replacement and / or maintenance, it is necessary to reset the radiation source mechanism.

[0003] Currently, the radiation source mechanism used in static computed tomography equipment is relatively large in size and weight. When moving the radiation source mechanism, it is necessary to lift it with a trolley (such as equipment like an overhead traveling vehicle, a crane, a gantry crane, etc.). At the time of reset, many people need to cooperate to ensure the relative position between the radiation source mechanism and the detector mechanism, and it is necessary to maintain the reset accuracy of the radiation source mechanism.

Summary of the Invention

Problems to be Solved by the Invention

[0004] To solve at least one of the above and other technical problems in the prior art, the present disclosure provides a radiation source mechanism and static computed tomography equipment, moves the radiation source mechanism by pushing the radiation source mechanism, and performs installation, repair, or replacement on the detector mechanism covered by the radiation source mechanism.

Means for Solving the Problems

[0005] To achieve the above object, an embodiment of the present disclosure provides a radiation source mechanism, which includes a main body that is attached to a frame of a computed tomography device and outputs radiation, and a tension module that restricts the position of the main body with respect to the frame. The tension module permits the main body to rotate between a closed position close to the frame and an open position away from the frame around a first axis of the tension module. A first support module is attached to a lower end of the main body to support the lower end of the main body to smoothly rotate around the first axis with respect to a first working surface where the lower end of the main body is located below a first support module. A part of the first support module has a detached state of detaching from the first working surface and a contact state of contacting the first working surface during a process in which the main body detaches from the closed position to adjust a contact area between the first support module and the first working surface.

[0006] In an exemplary embodiment, when the first support module is in the contact state, the first support module forms rolling friction with the first working surface.

[0007] In an exemplary embodiment, the tension module includes a first connecting member attached to the main body and a rotating portion rotatably provided between the first connecting member and the frame to support the main body to rotate between the closed position and the open position.

[0008] In an exemplary embodiment, the tension module further includes a first locking member that restricts movement of the first connecting member with respect to the frame when the rotating portion is in the closed position.

[0011] In an exemplary embodiment, the first locking member is removably provided between the side plate and the frame, and includes a first bolt that holds the first connecting member in a position in contact with the frame.

[0012] In an exemplary embodiment, the rotating portion includes a first hinge base provided on the frame, and a pull rod having one end rotatably provided on the first hinge base and the other end connected to the first connecting member. The axis around which the pull rod rotates around the first hinge base defines the first axis.

[0013] In an exemplary embodiment, the rotating portion further includes a second hinge base. The second hinge base is attached to the end face of the first connecting member facing the pull rod, and the other end of the pull rod is rotatably attached to the second hinge base such that the pull rod has a degree of freedom to rotate around a second axis of the second hinge base.

[0014] In an exemplary embodiment, at least one arc-shaped groove is provided on the upper end face of the first working surface. The center of the arc of the arc-shaped groove is located on the first axis. The first support module is a plate-shaped member for installing a support body, and includes a plate-shaped member provided with through holes at positions corresponding to at least a part of it and each of the arc-shaped grooves, and a telescopic portion provided at a position corresponding to the through holes of at least a part of the plate-shaped member.

[0015] In an exemplary embodiment, the telescopic part includes a universal ball provided at an end facing the first working surface of the telescopic part. The universal ball is configured to move between a contact position in contact with the first working surface and a detachment position away from the first working surface. When the first support module is in a detached state, the universal ball is located in the through hole and at a detachment position away from the arc-shaped groove. When the first support module is in a contact state, at least a part of the universal ball extends from the through hole so as to abut against the bottom of the arc-shaped groove and is located at a contact position where it rolls along the arc-shaped groove following the rotation of the main body.

[0016] In an exemplary embodiment, the telescopic part further includes a base provided on the plate-shaped member, a screw externally fitted and fixed to the base and screwed with the base, and a universal ball sheet provided at the lower end of the screw. The universal ball is provided in the universal ball sheet.

[0017] In an exemplary embodiment, the first support module further includes a second connecting member that restricts the main body to the plate-shaped member.

[0018] In an exemplary embodiment, so as to restrict the main body to the plate-shaped member, the end of the second connecting member facing the main body protrudes from the upper end surface of the plate-shaped member and extends into the main body.

[0019] In an exemplary embodiment, the first support module further includes a second locking member removably provided between the plate-shaped member and the first working surface so as to restrict the relative position between the plate-shaped member and the first working surface.

[0020] In an exemplary embodiment, at least one auxiliary arc-shaped groove is further provided on the first working surface. The arc-shaped groove and the auxiliary arc-shaped groove have the same arc center, and the radius of the auxiliary arc-shaped groove is larger than the radius of the arc-shaped groove.

[0021] In an exemplary embodiment, a through hole is provided at a position corresponding to at least a part of the plate-like member and the auxiliary arcuate groove, and the telescopic part is provided at a position corresponding to the through hole of at least a part of the plate-like member.

[0022] In an exemplary embodiment, it further includes a second support module provided on the lower end surface of the plate-like member. When a part of the plate-like member rotates in a state of detaching from the first working surface, the second support module abuts between the plate-like member and a second working surface parallel to the first working surface so as to support the part of the plate-like member protruding from the first working surface against the second working surface.

[0023] In an exemplary embodiment, the second support module includes a wheel-shaped member. When a part of the plate-like member rotates in a state of detaching from the first working surface, the wheel-shaped member abuts against the second working surface so as to support the plate-like member and guide the plate-like member to rotate along the second working surface.

[0024] In an exemplary embodiment, the second support module is removably attached to the lower end surface of the plate-like member.

[0025] In an exemplary embodiment, the second support module is telescopically provided on the lower end surface of the plate-like member and is configured to move between a retracted position where it detaches from the second working surface and an extended position where it abuts against the second working surface.

[0026] Embodiments of the present disclosure also provide a computed tomography device, including a frame that defines a detection channel for placing a detection target, a plurality of detector arrays, at least one detector mechanism provided on a side wall of the frame, and at least one radiation source mechanism according to any one of the claims. At least one detector array is respectively provided between the radiation source mechanism and the frame, and the radiation source mechanism is configured to move between a closed position where it shields the detector mechanism and an open position where it opens the detector mechanism.

[0027] In an exemplary embodiment, the upper end of the frame extends outward along the horizontal direction to form a first protrusion, a second protrusion parallel to the first protrusion is formed at the lower end of the frame, the detector mechanism is provided between the first protrusion and the second protrusion, and a first working surface is formed above the second protrusion.

[0028] In an exemplary embodiment, it includes two said detector mechanisms respectively provided outside two opposite side walls of the frame, and two radiation source mechanisms respectively provided outside the two detector mechanisms. Each detector mechanism receives radiation from a radiation source mechanism far away from the detector mechanism and penetrating the object to be detected.

[0029] In an exemplary embodiment, the detector mechanism receives scattered radiation caused by radiation from the detector mechanism scattering from the object to be detected.

[0030] According to the radiation source mechanism and the static computed tomography equipment disclosed in the present disclosure, the tension module establishes a connection relationship between the upper part of the main body and the frame, and pulls the main body to prevent the main body from falling during the process of rotating between the closed position and the open position. The first support module is provided between the main body and the first working surface. When the main body is in the closed position, a part of the first support module is in a detached state of detaching from the first working surface. Thereby, at least some other parts of the first support module are in surface contact with the first working surface, and the relative position between the main body and the first working surface is maintained by the frictional force formed between the first support module and the weight of the main body, which helps to maintain the stability of the main body. When the main body moves from the closed position to the open position, a part of the first support module is in a contact state of line contact or point contact with the first working surface, and the frictional force required to change the position of the main body relative to the first working surface is reduced. Thereby, the operator can move the main body to the open position without using a trolley, and for the convenience of installation, repair, or replacement, the detector mechanism is at least partially exposed outside the radiation source mechanism.

[0036] According to the overall inventive concept of the present disclosure, a radiation source mechanism and a static computed tomography scanning device are provided.

[0037] FIG. 1 is a perspective view of a static computed tomography scanning device according to an exemplary embodiment of the present disclosure.

[0038] As shown in FIG. 1, according to an exemplary embodiment of the present disclosure, a static computed tomography scanning device is provided that includes a frame 1 and to which a radiation source mechanism is attached to the frame 1.

[0039] FIG. 2 is a perspective view of a radiation source mechanism according to an exemplary embodiment of the present disclosure. Exemplary embodiments of the present disclosure provide a radiation source mechanism 2, which, as shown in FIG. 2, includes a main body 22, a tension module 21, and a first support module 23. The main body 22 outputs radiation. The tension module 21 restricts the position of the main body 22 with respect to the frame 1 and permits the main body 22 to rotate between a closed position close to the frame 1 and an open position away from the frame 1 around a first axis of the tension module 21. The first support module 23 is attached to the lower end of the main body 22 to support the lower end of the main body 22 to smoothly rotate around the first axis with respect to a first working surface where the lower end of the main body 22 is located below the first support module 23. In order to adjust the contact area between the first support module 23 and the first working surface, a part of the first support module 23 has a disengaged state of disengaging from the first working surface and a contact state of contacting the first working surface during the process in which the main body 22 disengages from the closed position.

[0040] In an exemplary embodiment, the main body 22 includes, but is not limited to, an X-ray source. Here, the main body 22 is not the point of protection of the present invention, and any radiation source that can be used in static computed tomography equipment in this field can be selected and applied, and no detailed description will be given.

[0041] In an exemplary embodiment, the tension module 21 is attached between the main body 22 and the frame 1.

[0042] Specifically, the tension module 21 includes, but is not limited to, being connected to at least one of the upper and side end faces of the main body 22.

[0043] In an exemplary embodiment, the tension module 21 includes at least one pivot, and one of the pivots has an axis extending substantially in the vertical direction as the first axis.

[0044] In an exemplary embodiment, the first support module 23 is provided on the lower end surface of the frame 1.

[0045] Specifically, in the projection formed in the vertical direction of the first support module 23, it at least partially overlaps with the lower end surface of the frame 1. It should be understood that the embodiments of the present disclosure are not limited to this.

[0046] For example, the first support module 23 is configured as a frame-like structure, and the frame-like structure is attached around the outer edge of the lower end surface of the main body 22 and covers the lower end of the main body 22.

[0047] In an exemplary embodiment, the first working surface includes, but is not limited to, any one of an end surface formed on the frame, the ground, and an end surface (such as a floor) of the space where the static computed tomography equipment is arranged.

[0048] In another exemplary embodiment, the tension module 21 is attached to another frame (not shown) other than the main body 22 and the frame 1.

[0049] Specifically, a frame is installed at a position outside the frame 1 and facing the main body 22, and the tension module 21 is provided between the frame and the main body 22.

[0050] Furthermore, the frame includes, but is not limited to, any one of a door shape, an arch shape, a crossbeam shape, a vertical beam shape, or other structural frames suitable for connecting the tension module 21.

[0051] In such an embodiment, the tension module 21 establishes a connection relationship between the upper part of the main body 22 and the frame 1, and pulls the main body 22 when the main body rotates between the closed position and the open position to prevent the main body from falling. The first support module 23 is provided between the main body 22 and the first working surface. When the main body is in the closed position, a part of the first support module is in a detached state of detaching from the first working surface, and at least some other parts of the first support module 23 are in surface contact with the first working surface. The frictional force formed between the first support module 23 and the main body 22 due to the self-weight of the first support module 23 and the main body 22 helps to maintain the relative position between the main body 22 and the first working surface and maintain the stability of the main body. When the main body 22 moves from the closed position to the open position, a part of the first support module is in a contact state of line contact or point contact with the first working surface, and the friction required to change the position of the main body 22 relative to the first working surface is small. Thereby, the operator can move the main body to the open position without using a trolley, and for the convenience of installation, repair, or replacement, the detector mechanism is at least partially exposed outside the radiation source mechanism.

[0052] According to an embodiment of the present disclosure, as shown in FIGS. 1 and 2, when the first support module 23 is in the contact state, the first support module 23 forms a rolling friction with the first working surface.

[0053] In such an embodiment, when the main body moves from the closed position to the open position, a part of the first support module 23 is in a contact state of surface contact with the first working surface. Thereby, a rolling friction is formed between the first support module 23 and the first working surface, and the operator can move the main body 22 to the open position without using a trolley. For the convenience of installation, repair, and replacement, the detector mechanism 3 is at least partially exposed outside the radiation source.

[0054] FIG. 3 is an enlarged view of part A (including the tension module part) shown in FIG. 2. According to an embodiment of the present disclosure, as shown in FIGS. 1 and 2, the tension module 21 includes a first connection member 214 and a rotating portion. The first connection member 214 is attached to the main body 22. The rotating portion is rotatably provided between the first connection member 214 and the frame 1 and supports the rotation of the main body between the closed position and the open position.

[0055] In an exemplary embodiment, the first connection member 214 is provided on the upper end surface of the main body 22. Furthermore, the rotating portion is provided between the first connection member 214 and the side wall of the frame 1.

[0056] In such an embodiment, the first connection member 214 is attached to the upper end surface of the main body portion 22, whereby the side end surface facing the detector mechanism 3 of the main body portion 22 is not blocked. The rotating portion connects the first connection member 214 to the frame 1 and gives the first connection member 214 the freedom to rotate around the first axis.

[0057] According to an embodiment of the present disclosure, as shown in FIGS. 1 and 2, the tension module 21 further includes a first locking member that restricts the movement of the first connection member 214 with respect to the frame 1 when the rotating portion is in the closed position.

[0058] In an exemplary embodiment, the first locking member is provided between the first connection member 214 and the frame 1, fixes the first connection member 214 to the frame 1, holds the first connection member 214 and the frame 1 in a position where they are attached to each other, and restricts the relative movement between the main body 22 and the frame 1.

[0059] In another exemplary embodiment, the first locking member is provided on the rotating portion. Specifically, the first locking member is provided on the rotation axis of the rotating portion and maintains the main body in the closed position by restricting the rotation of the rotation axis.

[0060] Furthermore, the axis of the rotation axis is limited to the first axis. In a specific embodiment, the rotation axis is rotatably provided within the hinge sheet. One end in the axial direction of the rotation axis is connected to the output end of the motor. The rotation of the rotation axis is driven by the torque output from the motor. When the motor is turned off, the rotation of the rotation axis is restricted.

[0061] Also, for example, a cylindrical member is externally fitted and fixed to the outside of the rotation axis, and a deep groove bearing is installed between the cylindrical member and the rotation axis. This deep groove bearing is filled with magnetorheological grease, and a coil is provided on the cylindrical member. When the coil is energized, the inner ring and outer ring of the bearing are in a locked state, and the magnetorheological grease in the bearing forms a Bingham fluid so that the rotation of the rotation axis with respect to the cylindrical member is restricted.

[0062] In such an embodiment, the first locking member restricts the relative position between the main body 22 and the frame 1 so that the main body 22 is held in the closed position covering the detection mechanism 3.

[0063] According to an embodiment of the present disclosure, the first connecting member 214 is configured to include, but not be limited to, a block structure. The first connecting member 214 is provided on the main body 22 and connected to the tension module 21.

[0064] Specifically, the block structure includes, but is not limited to, being configured in shapes such as a substantially cube, a cylinder, an elliptical cylinder, and other polygonal cylinder shapes. Thereby, the first connecting member 214 and the main body 22 are effectively and stably connected.

[0065] According to an embodiment of the present invention, as shown in FIGS. 1 to 3, the first connecting member 214 is configured to include, but not be limited to, a frame structure. The first connecting member 214 includes a bottom plate, side plates, and vertical plates. The bottom plate is provided at the upper end of the main body 22. The side plates are orthogonal to the bottom plate and are attached to the mounting surface of the frame 1 via the first locking member. The vertical plates are orthogonal to the bottom plate and the side plates and are connected to one end of the rotating portion.

[0066] In an exemplary embodiment, the first connecting member 214 includes, but is not limited to, at least one bottom plate, at least one side plate, and two vertical plates.

[0067] Specifically, the bottom plate forms the bottom surface of the cubic structure. A side plate is provided at one end of the bottom plate facing the frame 1, and vertical plates are respectively provided at both ends of the side plate (the left end and the right end shown in FIG. 3).

[0068] Furthermore, the bottom plate is fixed to the upper end surface of the main body 22 via the second bolt 216. In addition, the connection forms of the bottom plate, the side plate, and the vertical plate include, but are not limited to, any one of welding, caulking, bolting, integral molding, etc. It should be understood that the embodiments of the present disclosure are not limited thereto.

[0069] For example, the first connecting member 214 includes, but is not limited to, a keel structure and any other arbitrary structure that can abut against a certain surface of the frame 1 when assembled to the main body 22.

[0070] In such an embodiment, the bottom plate is fixed to the main body 22, the side plate is connected to the frame 1 via the first locking member, the vertical plate is disposed between the bottom plate and the side plate, improving the structural strength of the first connecting member 214, and can more effectively prevent the main body 22 from tipping over when connected to the frame 1.

[0071] According to an embodiment of the present invention, as shown in FIGS. 1 to 3, the first locking member includes, but is not limited to, the first bolt 215. The first bolt 215 is removably provided between the side plate and the frame 1 and can hold the first connecting member 214 at a position in contact with the frame 1.

[0072] In an exemplary embodiment, when the main body is in the closed position, screw holes are provided in at least a part covered by the side plate of the frame 1, through holes are formed in the side plate at positions corresponding to the orthographic projection direction of the screw holes in the horizontal direction, and the first bolt 215 is fixed by penetrating the frame 1.

[0073] In such an embodiment, with the first bolt 215 screwed into the threaded hole, a large tensile force is applied to the main body in the form of screw engagement, and the stability of the main body in the closed state can be maintained.

[0074] In another exemplary embodiment, an insertion groove (not shown) is provided in one of the frame 1 and the side plate, and an insertion block (not shown) corresponding to the shape and size of the insertion groove is provided in the other of the frame 1 and the side plate. With the rotating part in the third position, the insertion block is fitted into the insertion groove. A pin hole is provided at one end of the insertion groove, and a pin is inserted into the insertion groove from the pin hole through the insertion groove and fitted into the insertion groove along the normal line perpendicular to the extending direction of the insertion groove, so that the insertion block can be held in the insertion groove.

[0075] In such an embodiment, the cooperation method of the insertion groove, the insertion block, and the pin can be used for the rapid connection between the frame 1 and the side plate.

[0076] According to an embodiment of the present disclosure, as shown in FIGS. 1 to 3, the rotating part includes a first hinge base 211 and a pull rod 212. One end (the left end shown in FIG. 2) of the pull rod 212 is rotatably provided on the first hinge base 211, and the other end (the right end shown in FIG. 2) of the pull rod 212 is connected to the first connecting member 214. The axis around which the pull rod 212 rotates around the first hinge base 211 defines the first axis.

[0077] According to an embodiment of the present disclosure, as shown in FIGS. 1 to 3, the rotating part further includes a second hinge base 213 attached to the end face of the first connecting member 214 facing the pull rod 212. The other end of the pull rod 212 is rotatably attached to the second hinge base 213. Thereby, the pull rod 212 has the freedom to rotate around the second axis of the second hinge base 213.

[0078] In an exemplary embodiment, the second hinge base 213 is provided on the vertical plate. Specifically, both ends of the pull rod 212 are rotatably provided on the first hinge base 211 and the second hinge base 213, respectively.

[0079] In an exemplary embodiment, both the first hinge base 211 and the second hinge base 213 are configured to rotate around their respective hinge axes along the horizontal direction.

[0080] Specifically, the axis of the hinge shaft at the end of the first hinge base 211 connected to the pull rod 212 defines the first axis.

[0081] Furthermore, the first axis is located outside the vertical orthographic projection of the main body portion 22. In such an embodiment, the first hinge base 211 and the attached hinge shaft provide the main body 22 with a degree of freedom to rotate around the first axis.

[0082] In another exemplary embodiment, both the first hinge base 211 and the second hinge base 213 are configured to rotate around their respective hinge axes in the horizontal direction.

[0083] Specifically, the axis of the hinge shaft connected to the end of the pull rod 212 of the second hinge base 213 defines the second axis.

[0084] Furthermore, the second axis is located inside the vertical orthographic projection of the main body portion 22. In such an embodiment, the second hinge base 213 and the attached hinge shaft provide the main body 22 with the freedom to rotate around the second axis. On the other hand, the second hinge base 213 compensates for the fitting differences among the first hinge base 211, the pull rod 212, and the first connecting member 214 due to machining accuracy and assembly errors, so that the pull rod 212 can rotate at as large an angle as possible around the first hinge base 211 to satisfy the complete movement between the closed position and the open position of the main body 22. On the other hand, when a guide groove is provided between the first support module 23 and the first working surface, the main body 22 can be rotated around the second hinge axis in a state of rotating to a position around the first hinge axis, thereby adjusting the relative positions of the main body 22, the frame 1, and / or the detector mechanism 3. Here, the cooperation relationship between the guide groove and the main body 22 and / or the first support module 23 is not the protection point of the present disclosure. The guide groove and the cooperating cylindrical slider in this field can be applied, and no further details will be described.

[0085] FIG. 4 is a partially enlarged view of the first support module of the radiation source mechanism of the exemplary embodiment shown in FIG. 2. FIG. 5 is a partial cross-sectional view of the telescopic part of the first support module of the exemplary embodiment shown in FIG. 4.

[0086] According to an embodiment of the present disclosure, as shown in FIGS. 1, 2, 4, and 5, at least one arc-shaped groove is provided on the upper end surface of the first working surface, and the center of the arc of the arc-shaped groove is located on the first axis. The first support module 23 includes a plate-shaped member 231 and a telescopic part 232. The plate-shaped member 231 is provided along the horizontal direction and can install the support body 22. Through holes are provided at positions corresponding to at least some of the arc-shaped grooves of the plate-shaped member 231. The telescopic part 232 is provided at a position corresponding to the through holes of at least some of the plate-shaped member 231.

[0087] According to an embodiment of the present disclosure, as shown in FIG. 5, the telescopic part 232 includes a universal ball 2322 provided at an end facing the first working surface of the telescopic part 232, and the universal ball 2322 is configured to move between a contact position in contact with the first working surface and a detachment position away from the first working surface. In a state where the first support module 23 is in a detached state, the universal ball 2322 is located in the through hole so as to detach from the detachment position of the arc-shaped groove. When the first support module 23 is in a contact state, at least a part of the universal ball 2322 protrudes from the through hole, abuts against the bottom of the arc-shaped groove, and is located at a contact position that rolls along the arc-shaped groove following the rotation of the main body.

[0088] In an exemplary embodiment, two arc-shaped grooves are provided on the first working surface, but it is not limited thereto.

[0089] Specifically, the two arc-shaped grooves are provided in a centrosymmetric manner with the projection formed in the vertical direction of the first axis as the center of the circle.

[0090] Furthermore, it should be understood that the projection formed in the vertical direction of the through hole provided in the plate-shaped member 231 is covered by the arc-shaped groove. The embodiments of the present disclosure are not limited thereto.

[0091] For example, one, three, four, five, or any other number of arc-shaped grooves are provided on the first working surface.

[0092] In an exemplary embodiment, the plate-shaped member 231 is provided with more telescopic parts 232 than the number of arc-shaped grooves, so that at least one universal ball 2322 can be accommodated in each arc-shaped groove in a state where the universal balls 2322 of each telescopic part 232 are all in the contact position.

[0093] In such an embodiment, the universal ball 2322 moves between a disengaged position where it disengages from the arc-shaped groove and a contact position where it abuts against the bottom of the arc-shaped groove under the action of the telescopic portion 232. The extending direction of the arc-shaped groove limits the translational direction of at least a part of the radiation source mechanism 2, thereby guiding the movement of the radiation source mechanism 2. When the universal ball 2322 is in the disengaged position, the lower end surface of the plate-like member 231 is in surface contact with the first working surface. In a state where the main body receives a horizontal moving pressure, a sliding friction is formed between the plate-like member 231 and the working surface, and the stability of the radiation source mechanism 2 can be effectively maintained. When the universal ball 2322 is in the contact position, a point contact is formed between the universal ball and the arc-shaped groove, thereby generating a rolling friction between the main body 22 and the first working surface. In this state, the frictional force to be overcome for translating the radiation source mechanism 2 is small, and the operator does not need the cooperation of the trolley and can manually push the translation of the radiation source mechanism 2 (including the operator applying pressure through the human body or a mechanical device).

[0094] According to an embodiment of the present disclosure, as shown in FIG. 5, the telescopic portion 232 includes a base 2323, a screw 2324, and a universal ball seat 2325. The base 2323 is provided on the plate-like member 231. The screw 2324 is externally fitted and fixed in the base 2323 and is screwed with the base 2323. The universal ball seat 2325 is provided at the lower end of the screw 2324. A universal ball 2322 is provided in the universal ball seat 2325. It should be understood that the embodiments of the present disclosure are not limited thereto.

[0095] For example, the screw 2324 can be replaced by a cylinder, a feed screw, and other mechanisms having a telescopic function, but is not limited thereto.

[0096] In an exemplary embodiment, the base 2323 is fixed to the plate-like member 231. Specifically, the base 2323 is fixed to the plate-like member 231 via the first screw 2321.

[0097] Furthermore, the universal ball seat 2325 (including the universal ball 2322) is coaxially fixed to the lower end of the screw 2324 as shown in FIG. 5. It should be understood that the embodiments of the present disclosure are not limited to this.

[0098] For example, the base 2323 can be fixed to the plate-like member 231 by any method such as bolts, caulking, welding, etc., but is not limited thereto.

[0099] In such an embodiment, due to the screwing between the screw 2324 and the base 2323, the universal ball 2322 can be pushed out from below the through hole by a large torque and abutted against the arc-shaped groove.

[0100] According to an embodiment of the present disclosure, as shown in FIG. 3, the first support module 23 further includes a second connecting member 235 that restricts the main body 22 to the plate-like member 231.

[0101] In an embodiment of the present disclosure, as shown in FIG. 3, the end portion of the second connecting member 235 facing the main body 22 protrudes from the upper end surface of the plate-like member 231 and extends into the main body 22 to restrict the main body 22 to the plate-like member 231.

[0102] In an exemplary embodiment, the second connecting member 235 is configured as a cylindrical structure, but is not limited thereto. One end of the cylindrical structure penetrates upward from the lower end of the plate-like member 231, and the other end of the cylindrical structure extends radially outward to form a flange and abuts against the end surface facing the flange of the plate-like member 231.

[0103] Furthermore, a groove for accommodating the cylindrical structure is provided at a position on the lower end surface of the main body 22 facing the cylindrical structure extending from the plate-like member 231.

[0104] In such an embodiment, the second connecting member 235 is fitted into the main body 22, effectively restricting the relative horizontal displacement between the main body 22 and the plate-like member 231, and the plate-like member 231 and the main body 22 can be integrally fixed.

[0105] In another exemplary embodiment, the second connecting member 235 is provided around the cylindrical structure passing upward from the lower end surface of the plate-shaped member 231, and further includes a plurality of second screws for fixing the second connecting member to the plate-shaped member 231 and the main body 22. It should be understood that the embodiments of the present disclosure are not limited thereto. For example, the main body 22 can be fixed to the plate-shaped member 231 by welding, caulking, mortise and tenon, or any other one method.

[0106] According to an embodiment of the present disclosure, as shown in FIG. 4, the first support module 23 is removably provided between the plate-shaped member 231 and the first working surface, and further includes a second locking member for restricting the relative position between the plate-shaped member 231 and the first working surface.

[0107] In an exemplary embodiment, the second locking member includes, but is not limited to, a third screw 234.

[0108] Specifically, a through hole is provided in the plate-shaped member 231, and a positioning hole corresponding to the position of the through hole is provided in the first working surface. With the through hole and the positioning hole aligned, the third screw 234 can be inserted into the positioning hole to restrict the relative position between the plate-shaped part 231 and the working surface.

[0109] FIG. 6 is a schematic perspective view when the radiation source mechanism of the exemplary embodiment shown in FIG. 2 swings to the open state.

[0110] According to an embodiment of the present disclosure, as shown in FIG. 6, at least one auxiliary arc-shaped groove 236 is also provided on the first working surface. The arc-shaped groove 233 and the auxiliary arc-shaped groove 236 have the same arc center, and the radius of the auxiliary arc-shaped groove 236 is larger than the radius of the arc-shaped groove 233.

[0111] According to an embodiment of the present disclosure, as shown in FIGS. 5 and 6, through holes are provided at positions corresponding to each of the auxiliary arc-shaped grooves in at least a part of the plate-shaped member 231. The telescopic part 232 is provided at a position corresponding to the through holes in at least a part of the plate-shaped member 231.

[0112] In an exemplary embodiment, two arcuate grooves 233 are provided on the first working surface, but it is not limited thereto.

[0113] Specifically, the two arcuate grooves 233 are provided in a substantially circular ring structure symmetrically about the center of the vertical projection along the first axis.

[0114] Furthermore, one auxiliary arcuate groove 236 is provided on the first working surface, but it is not limited thereto.

[0115] In an exemplary embodiment, four telescopic parts 232 are respectively provided at the four corners of the plate-shaped member 231, but it is not limited thereto. However, the universal balls 2322 of the two telescopic parts 232 are in contact with the groove bottom and / or groove wall of the arcuate groove 233 in the contact position, and the universal balls 2322 of the other two telescopic parts 232 are in contact with the groove bottom and / or groove wall of the auxiliary arcuate groove 236 in the contact position.

[0116] In such an embodiment, the arcuate groove 233, the auxiliary arcuate groove 236, and the plurality of telescopic parts 232 disperse the pressure applied to the plate-shaped member 231 by the main body 22, so that the radiation source mechanism 2 receives stress uniformly during the translation process, prevents the main body 22 from tipping due to non-uniform stress, and can improve the smoothness during the translation process of the main body 22.

[0117] According to an embodiment of the present invention, as shown in FIG. 6, the radiation source mechanism 2 further includes a second support module 24 provided on the lower end surface of the plate-shaped member 231. When a part of the plate-shaped member 231 rotates until it detaches from the first working surface, the second support module 24 abuts between the plate-shaped member 231 and a second working surface parallel to the first working surface, and supports the portion extending from the first working surface of the plate-shaped member 231 with respect to the second working surface.

[0118] In an exemplary embodiment, the first working surface is represented by a plane formed by the upper end surface of the second protruding portion 12 of the bracket.

[0119] Furthermore, the second working surface is represented by a plane formed by the ground below the bracket.

[0120] In such an embodiment, the plate-like member 231 is rotated to the position shown in FIG. 5, and a part of the plate-like member 231 (for example, the right end shown in FIG. 6) is detached from the first working surface and is in a state of being suspended from the first working surface. The second support module 24 extends in the longitudinal direction, and both ends of the second support module 24 are respectively in contact with the lower end surface of the plate-like member 231 and the second working surface, supporting the plate-like member 231 and the main body 22. Thereby, due to the suspension of the plate-like member 231, it is possible to prevent the main body 22 from tipping over due to the deviation of the center.

[0121] According to an embodiment of the present disclosure, as shown in FIG. 6, the second support mechanism includes, but is not limited to, a wheel-shaped member. When a part of the plate-like member 231 rotates to a state of being detached from the first working surface, the wheel-shaped member abuts on the second working surface, supports the plate-like member 231, and guides the plate-like member 231 to rotate along the second working surface.

[0122] In an exemplary embodiment, the wheel-shaped member includes, but is not limited to, a universal wheel 241.

[0123] Specifically, the universal wheel 241 is provided on the lower end surface of the plate-like member 231, and when one end of the plate-like member 231 (for example, the right end shown in FIG. 6) rotates to a state of being detached from the first working surface, it supports the plate-like member 231 and the main body 22.

[0124] In such an embodiment, it can be applied to a usage scenario where the size of the frame 1 is restricted. When the frame 1 cannot satisfy the condition that the plate-shaped member 231 rotates to a complete stroke, the universal wheel 241 can support and guide the plate-shaped member 231 after the plate-shaped member 231 detaches from the first working surface. This is advantageous for improving the stability of the radiation source mechanism 2 and expanding the usage scenario of the radiation source mechanism 2. It should be understood that the embodiments of the present disclosure are not limited thereto.

[0125] For example, the second support mechanism may include pads, supports, and other structures that fill the gap in the vertical direction between the first working surface and the second working surface.

[0126] According to an embodiment of the present disclosure, as shown in FIG. 6, the second support module 24 is detachably provided on the lower end surface of the plate-shaped member 231.

[0127] In an exemplary embodiment, a plurality of mounting holes are provided in the plate-shaped member 231 in advance. In a state where the position where the mounting hole of the plate-shaped member 231 is provided moves to the position where it detaches from the first working surface, the operator can arrange the second support module 24 between the lower end surface of the plate-shaped member 231 and the second working surface, and fix the second support module 24 to the mounting hole.

[0128] In such an embodiment, the second support module 24 has high flexibility, and the operator can select a second support module 24 having an appropriate size and strength according to the actual usage scenario. Furthermore, the adaptability of the second support module 24 is also wide. For example, in a scene where the second working surface is relatively flat, the second support module 24 can use the universal wheel 241. Also, for example, in a scene where the second working surface has a partially protruding and non-flat surface, the second support module 24 can adopt at least one of a support rod, a pad, or other members capable of supporting the plate-shaped member 231.

[0129] FIG. 7 is a partial schematic diagram of the second support module of the radiation source mechanism of the exemplary embodiment shown in FIG. 2.

[0130] According to an embodiment of the present disclosure, as shown in FIG. 7, the second support module 24 is disposed on the lower end surface of the plate-like member 231 so as to be telescopic, and is configured to move between a retracted position where it detaches from the second working surface and an extended position where it abuts against the second working surface.

[0131] In an exemplary embodiment, the second support module 24 includes, but is not limited to, any one of a telescopic cylinder, an electric push rod, a feed screw, and other structures having a telescopic function and a lifting function.

[0132] Specifically, the plate-like member 231 and / or the frame 1 are provided with concave grooves. In the retracted state, the second support module 24 is located within the concave grooves, and in the extended state, it extends from the concave grooves and is supported between the plate-like member 231 and the second working surface.

[0133] In another exemplary embodiment, the second support module 24 includes, but is not limited to, a telescopic universal wheel 241.

[0134] Specifically, the telescopic form of the universal wheel 241 includes, but is not limited to, vertical telescoping, horizontal folding, a universal wheel 241 having other telescopic functions, and a universal wheel frame mechanism. It should be noted that the specific telescoping method of the universal wheel 241 is not the protection point of the present disclosure. Any telescopic universal wheel 241 known in the art can be selected and applied, and will not be described in more detail here.

[0135] FIG. 8 is a perspective view of a static computed tomography device according to an exemplary embodiment of the present disclosure, with the radiation source mechanism in an open state.

[0136] Exemplary embodiments of the present disclosure also provide a static computed tomography device, which includes a frame 1, at least one detector mechanism 3, and at least one radiation source mechanism 2, as shown in FIGS. 1 and 8. The frame 1 defines a detection channel 13 for placing the object to be detected. The detector mechanism 3 is provided on the side wall of the frame 1, and each detector mechanism 3 includes a plurality of detector arrays. The detector arrays 3 are respectively provided between the radiation source mechanism 2 and the frame 1. The radiation source mechanism 2 is configured to move between a closed position that shields the detector mechanism 3 and an open position that opens the detection mechanism 3.

[0137] In such an embodiment, the radiation source mechanism 2 is rotatably provided on the frame 1. In the state of the open position, the radiation source mechanism 2 opens the detector mechanism 3 so that an operator can perform curing and / or maintenance on the detector mechanism 3. In the state of the closed position, it is reset to a position that shields the detector mechanism 3 so that the static computed tomography device can perform tomographic imaging operations.

[0138] According to an embodiment of the present disclosure, as shown in FIG. 8, the upper end of the frame 1 extends outward in the horizontal direction to form a first protrusion 11, and the lower end of the frame 1 forms a second protrusion parallel to the first protrusion 11. The detector mechanism 3 is provided between the first protrusion 11 and the second protrusion 12, and a first working surface is formed above the second protrusion 12.

[0139] In such an embodiment, the radiation source mechanism 2 and the detector mechanism 3 have high integrity, and the radiation source mechanism 2 is provided on the frame 1 so as to facilitate the overall installation, detection, and transportation of the static computed tomography device.

[0140] According to an embodiment of the present disclosure, as shown in FIG. 8, a static computed tomography device includes two detector mechanisms 3 respectively provided on the outer sides of two opposite side walls of a frame 1, and two radiation source mechanisms 2 respectively provided on the outer sides of the two detector mechanisms 3. Each detector mechanism 3 receives radiation from a radiation source mechanism 2 that is far from the detector mechanism 3 and that has passed through the object to be detected.

[0141] In such an embodiment, the detector mechanism 3 receives radiation that passes through the object to be detected and is output by the opposing radiation source mechanism 2.

[0142] According to an embodiment of the present disclosure, as shown in FIG. 8, the detector mechanism 3 receives scattered radiation based on the scattering of radiation from the detector mechanism 3 by the object to be detected.

[0143] In such an embodiment, the tension module 21 is provided on the first protrusion 11, and the first support module 23 is provided between the second protrusion 12 and the main body 22. When the main body is in the closed position, the first support module 23 is in the contact position, and the first support module 23 forms a sliding friction along the first working surface between the main body and the first working surface by its own action, and can maintain the stability of the main body in the closed position. When the main body moves away from the closed position to the open position, a part of the first support module 23 is in a contact state of contacting the first working surface, and a rolling friction is formed between the first support module 23 and the first working surface. Thereby, an operator can move the main body 22 to the open position without using a trolley, and for the convenience of installation, maintenance, or replacement, the detector mechanism 3 is at least partially exposed outside the radiation source mechanism.
