[0043] In order to make the technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0044] Figure 1 to Figure 3 Schematic diagram of the detection test device of the field shaping module in the embodiment of the utility model. Figure 1 to Figure 3 As shown, the detection and testing device of the portal shaping module in the embodiment of the present application may include: a base 10, a rotating assembly 20, a mounting plate 30, a fixing plate 40 and a driving device 50;
[0045] The two ends of the mounting plate 30 are respectively provided with a first connecting plate 31 and a second connecting plate 32; the first connecting plate 31 is rotatably connected to the base 10; the second connecting plate 32 is rotatably connected to the driving device 50;
[0046] The driving device 50 is used to drive the mounting plate 30 to rotate;
[0047] A through hole is provided in the middle of the mounting plate 30;
[0048] The rotating assembly 20 is arranged around the through hole of the mounting plate 30;
[0049] The fixing plate 40 is disposed on the top of the rotating assembly 30 ; a mounting hole corresponding to the through hole of the mounting plate 30 is disposed in the middle of the fixing plate 40 .
[0050] In the technical solution of the present application, when the detection test device of the above-mentioned field shaping module is used to perform performance verification on the BSM to be tested, the mounting frame of the BSM to be tested can be fixedly connected to the above-mentioned fixed plate, and then the BSM to be tested can be driven by the above-mentioned rotating assembly through the fixed plate to rotate parallel to the extension direction of the mounting plate (that is, the rotation axis is perpendicular to the extension direction of the mounting plate). In addition, since the first connecting plate at one end of the mounting plate is rotatably connected to the base, and the second connecting plate at the other end of the mounting plate is rotatably connected to the driving device, the driving device can drive the mounting plate to rotate around a preset rotation axis (for example, the rotation axis of the first connecting plate and the second connecting plate) (for example, the entire mounting plate can be flipped), thereby driving the BSM to be tested to rotate accordingly around the preset rotation axis. At the same time, since through holes and mounting holes are respectively provided on the mounting plate and the fixed plate, it is also convenient to test and / or operate the BSM to be tested from the top and bottom directions, thereby completing the performance verification of the field shaping module.
[0051] In addition, in the technical solution of the present application, the above-mentioned detection test device of the portal shaping module can be realized by a variety of specific implementation methods. The following will take several specific methods as examples to introduce the technical solution of the present application in detail.
[0052] For example, as an example, in a specific embodiment of the present application, the rotating assembly 20 may include: a first gear 21, a second gear 22 and a first driver 23;
[0053] The first gear 21 is rotatably mounted around the through hole of the mounting plate 30, a through hole penetrating the through hole of the mounting plate 30 is provided in the middle of the first gear 21, and the top of the first gear 21 is fixedly connected to the fixing plate 40;
[0054] The second gear 22 is disposed on one side of the first gear 21 and meshes with the first gear 21;
[0055] The first driver 23 is connected to the second gear 22 and is used to drive the second gear 22 to rotate.
[0056] In the technical solution of the present application, since the second gear is meshed with the first gear, the second gear can be driven to rotate by the above-mentioned first driver, thereby driving the first gear to rotate as well, so that the BSM to be tested can be driven to rotate parallel to the extension direction of the mounting plate (that is, the rotation axis is perpendicular to the extension direction of the mounting plate) by the fixed plate arranged on the top of the first gear.
[0057] In addition, as an example, in a specific embodiment of the present application, the detection test device of the portal shaping module may further include: one or more sensors;
[0058] The sensor is used to test the performance of the radiation field shaping module.
[0059] In addition, as an example, in a specific embodiment of the present application, the sensor may be disposed on the rotating component 20 .
[0060] For example, as an example, in a specific embodiment of the present application, the sensor may be disposed on the first gear 21 of the rotating assembly 20 .
[0061] In addition, as an example, in a specific embodiment of the present application, the base may include: a plurality of support columns 11 and a plurality of beams 12;
[0062] The cross beam 12 is disposed between the support columns 11 .
[0063] A frame structure serving as a base can be formed by the plurality of support columns and the plurality of cross beams.
[0064] For example, as an example, in a specific embodiment of the present application, the base 10 may include: four support columns and eight cross beams. Of course, other numbers of support columns and cross beams may also be used, which will not be listed here.
[0065] In addition, as an example, in a specific embodiment of the present application, the base may further include: a plurality of moving components 13;
[0066] The moving components 13 are respectively arranged at the bottom of each supporting column 11 .
[0067] In addition, as an example, in a specific embodiment of the present application, the moving component 13 may include: universal wheels and foot brakes.
[0068] Therefore, by means of the above-mentioned moving assembly, the detection and testing device of the above-mentioned portal shaping module can be moved to a desired position relatively conveniently.
[0069] In addition, as an example, in a specific embodiment of the present application, the first bearing seat 14 and the second bearing seat 15 may be fixedly disposed at both ends of the top of the base 10, respectively (for example, the first bearing seat 14 and the second bearing seat 15 may be fixedly disposed on two beams 12 located at the top of the base, respectively);
[0070] A first bearing is rotatably disposed on the first bearing seat 14;
[0071] The first connecting plate 31 is rotatably connected to one end of the first bearing;
[0072] A second bearing is rotatably disposed on the second bearing seat 15; the rotation axes of the second bearing and the first bearing are located on the same straight line;
[0073] The second connecting plate 32 is rotatably connected to one end of the second bearing; and the driving device 50 is rotatably connected to the other end of the second bearing.
[0074] Therefore, the first connecting plate can be rotatably connected to the base through the above-mentioned first bearing, and the second connecting plate can be rotatably connected to the driving device through the above-mentioned second bearing. Since the first connecting plate and the second connecting plate are fixedly arranged at both ends of the mounting plate, the driving device can drive the second connecting plate to rotate around the rotation axis of the second bearing through the second bearing, thereby driving the mounting plate to rotate around the rotation axis of the second bearing (for example, the entire mounting plate can be flipped), thereby driving the BSM to be tested fixed on the mounting plate to generate corresponding rotation around the rotation axis of the second bearing.
[0075] In addition, as an example, in a specific embodiment of the present application, the base may further include: a lock 16;
[0076] The locker 16 is disposed on the base 10 and is used to fix the first connecting plate 31 and / or the second connecting plate 32 at a preset position.
[0077] For example, as an example, in a specific embodiment of the present application, the locker 16 may include: a fastener 61, a sleeve 62 and a rotary plunger 63;
[0078] The fastener 61 is fixedly connected to the base 10; the fastener 61 is provided with a mounting hole;
[0079] The sleeve 62 is inserted into and fixed in the mounting hole of the fastener 61; a through hole is provided in the middle of the sleeve 62;
[0080] The rotary plunger 63 is inserted into the through hole of the sleeve 62; the bottom end and the top end of the rotary plunger 63 extend from both ends of the through hole of the sleeve 62 respectively, and a wrench 64 perpendicular to the rotary plunger 63 is provided at the top end of the rotary plunger 63;
[0081] One or more insertion holes 33 for accommodating the bottom end of the rotating plunger 63 are disposed on the first connecting plate 31 and / or the second connecting plate 32 .
[0082] When locking is required, the bottom end of the rotating plunger can be pushed forward by a wrench until the bottom end of the rotating plunger is inserted into a certain plug hole on the first connecting plate or the second connecting plate, thereby fixing the first connecting plate or the second connecting plate at a preset position, locking the first connecting plate or the second connecting plate, and thus fixing the BSM to be tested at a preset position. When locking is not required, the wrench can be pulled to make the bottom end of the rotating plunger withdraw from the plug hole, thereby releasing the lock on the first connecting plate or the second connecting plate.
[0083] Therefore, the first connecting plate or the second connecting plate can be locked by the above-mentioned locking device, and the BSM to be tested can be fixed at a preset position.
[0084] In addition, as an example, in a specific embodiment of the present application, the top end of the sleeve may also be provided with a bevel.
[0085] Therefore, when locking is required, the wrench can be rotated so that the wrench is rotated to the inclined surface away from the top end of the sleeve, so that the bottom end of the rotating plunger can be pushed forward by the wrench; when locking is not required, the wrench can be pulled to make the bottom end of the rotating plunger withdraw from the socket, and the wrench can be rotated to the side of the inclined surface close to the top end of the sleeve, so that the wrench abuts against the top end of the inclined surface, thereby jamming the wrench and preventing the bottom end of the rotating plunger from extending forward and contacting the first connecting plate or the second connecting plate.
[0086] In addition, as an example, in a specific embodiment of the present application, the first driver may be a driving motor.
[0087] For another example, in a specific embodiment of the present application, the first driver may also be a manual driver (for example, a driver provided with a crank handle).
[0088] For another example, as an example, in a specific embodiment of the present application, the manual driver may include: a crank handle and a multi-stage gear transmission pair;
[0089] The crank handle is rotationally connected to the multi-stage gear transmission pair;
[0090] The multi-stage gear transmission pair is connected to the second gear.
[0091] For another example, as an example, in a specific embodiment of the present application, the shaking handle can be set at the bottom of the mounting plate; the multi-stage gear transmission pair rotates through the mounting plate and is connected to the second gear.
[0092] Therefore, by rotating the shaking handle, the second gear can be rotated, thereby driving the first gear to rotate.
[0093] In addition, as an example, in a specific embodiment of the present application, the driving device may be a driving motor or a manual drive.
[0094] In summary, in the technical solution of the present application, since a base, a rotating assembly, a mounting plate, a fixed plate and a driving device are provided, the mounting frame of the BSM to be tested can be fixedly connected to the above-mentioned fixed plate, and the BSM to be tested can be driven by the above-mentioned rotating assembly to rotate in parallel to the extension direction of the mounting plate (that is, the rotation axis is perpendicular to the extension direction of the mounting plate), and the mounting plate is driven by the driving device to rotate around the preset rotation axis, thereby driving the BSM to be tested to rotate accordingly around the preset rotation axis. At the same time, since through holes and mounting holes are respectively provided on the mounting plate and the fixed plate, the BSM to be tested can be tested and / or operated from two directions, the top and the bottom, so as to complete the performance verification of the field shaping module.
[0095] The detection test device of the above-mentioned radiation field shaping module in the present application can adopt a frame style as a whole, with a simple structure and low manufacturing cost. It is not necessary to assemble the BSM to be tested to the whole machine of the radiotherapy equipment to verify the performance of the BSM to be tested. The BSM to be tested can also be rotated at any angle and its angle can be adjusted to test the performance of the BSM to be tested at any angle. In addition, since the mounting plate can be turned over and has a through hole and a mounting hole in the middle, it is also convenient to install and disassemble the BSM to be tested, and it is also convenient to test the BSM to be tested from the upper and lower directions and replace and compare parts.
[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
