Description

Technical Field

[0001] This invention relates to the field of drop test technology, and in particular to an apparatus and method for drop stress testing of radioactive containers. Background Technology

[0002] Currently, the most basic test item for transport packaging before it is put into transport use is the drop test, as stipulated in standards such as GB4857.5 "Vertical impact drop test of transport packaging" and the international standard ISO2248 "Packaging - Vertical impact drop test of fully loaded transport packaging".

[0003] A survey of domestic and international drop test equipment revealed that most existing systems use motors to automatically lift samples to a set drop height. However, adjusting the sample's drop posture relies on manual operation, resulting in wasted manpower. Dongguan Hongjin Testing Instruments Co., Ltd. has designed and manufactured a dual-arm drop test device. The drop height can be set via an operating panel, and a built-in controller lifts the sample according to the set height. For edge and corner drops, the sample's posture is manually adjusted before being placed on the dual-arm support and secured with the upper corner retainers. Pressing the drop button on the operating panel causes the dual-arm support to flip downwards and detach from the sample. However, this design suffers from inaccurate drop posture adjustment.

[0004] Existing drop test equipment uses bottom substrate sensors to collect data, aiming to indirectly reflect and analyze the drop performance of the dropped component by measuring the instantaneous acceleration of the container. However, it does not directly collect data on the actual stress changes when the container falls onto the contact surface, and therefore cannot intuitively reflect the stress changes at a certain part of the container during the drop. Summary of the Invention

[0013] Furthermore, the rotating structure includes a rotating drive structure, a first rotating support frame, a second rotating support frame, a rotating flange shaft, and an angle limiting structure.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] This invention provides a device for drop stress testing of radioactive containers, comprising a housing 1, a support platform 2, a height adjustment structure 3, a horizontal adjustment structure 4, a rotating structure 5, and a clamping assembly 6 for securing the radioactive container. The support platform 2 is disposed within the housing 1, and a replaceable contact surface base 7 is provided at the bottom of the housing 1. The height adjustment structure 3 is disposed on the support platform 2, and the horizontal adjustment structure 4 is connected to the height adjustment structure 3, allowing the height adjustment structure 3 to adjust the position of the horizontal adjustment structure 4 along the height direction. The rotating structure 5 is connected to the horizontal adjustment structure 4, allowing the horizontal adjustment structure 4 to adjust the position of the rotating structure 5 along the horizontal direction. The clamping assembly 6 is connected to the rotating structure 5, allowing the rotating structure 5 to adjust the angle of the clamping assembly 6.

[0023] When using the device provided by this invention, the container to be tested (radioactive container) is fixed on the clamp assembly 6; the clamp assembly 6 and the container are rotated by the rotating structure 5 to adjust the container's posture; then the container is raised to a specified height by the height position adjustment structure 3; the container is moved above the contact surface base 7 by the horizontal position adjustment structure 4; then the clamp assembly 6 is controlled to release the container to perform a drop stress test. Using the device provided by this invention avoids the need for manual adjustment of the container's posture.

[0024] Support wheels (or support columns) are provided on the support base plate 101 at the bottom of the housing 1 to form a placement chamber below the support base plate 101. A contact surface base 7 is disposed in the placement chamber. A hole is formed in the support base plate 101. A support platform 2 supports the support base plate 101. The position of the clamp assembly 6 can be adjusted to be directly above the hole. See also... Figure 1 and Figure 2 The diagram illustrates the contact surface base 7. Support wheels (with brakes) are located at the four corners of the support base plate 101. The contact surface base 7 can be inserted from one side of the placement compartment and is supported on the ground. A limiting plate can be provided on the support base plate 101 to limit the insertion depth of the contact surface base 7 into the placement compartment. A guide structure is also provided on the support base plate 101 to guide the insertion direction of the contact surface base 7. The guide structure can be two parallel, spaced strips, with the distance between the two strips slightly greater than the width of the contact surface base 7.

[0025] The support base plate 101 has holes so that when the clamp assembly 6 releases the container, the container falls onto the contact surface base 7.

[0026] The "drawer-type" contact surface base is designed, and contact surface bases made of different materials can be used to simulate various drop environments, thereby adapting to the diversity of drop environment changes.

[0027] See Figure 2The support platform 2 is supported within the housing 1 (on the support base plate 101) by a linear drive mechanism 8. The linear drive mechanism 8 is a pneumatic cylinder or a hydraulic cylinder; there may be two or more linear drive mechanisms 8, see [link to relevant documentation]. Figure 2 The diagram illustrates two linear drive mechanisms 8, which are spaced apart along the width of the housing 1. The linear drive mechanisms 8 are used to adjust the height of the support platform 2. When using the device, personnel first enter the housing 1 through the door 102, lower the support platform 2 to its lowest position, and then clamp the container onto the clamp assembly 6.

[0028] See Figure 1 The housing 1 includes a rigid housing 103 and a baffle 104. The rigid housing 103 is a cylindrical structure with an open top and a door 102 is provided on it. The baffle 104 includes a circumferential cylindrical baffle and a top baffle. One end of the circumferential cylindrical baffle is connected to the top of the rigid housing 103, and the other end is connected to the top baffle. The circumferential cylindrical baffle is a foldable structure. A support rod 201 is provided on the support platform 2. The height of the support rod 201 is not lower than the height of the height adjustment structure 3. The support rod 201 is connected to the top baffle and is used to support the top baffle. By providing the baffle 104, a protective function can be achieved.

[0029] Preferably, see Figure 7 and Figure 9 The device also includes a through module 9, which is mounted on the rotating structure 5 (mounted on the second rotating support frame 502); the through module 9 includes a telescopic mechanism and a clamping head 901, which is connected to the telescopic mechanism; the clamping head 901 is a clamp structure, and a drive motor 902 is connected to the fastening bolt of the clamping head 901.

[0030] Regarding the telescopic mechanism of the through module 9, it can be a pneumatic cylinder or a hydraulic cylinder; regarding the clamping head 901, see [link to relevant documentation]. Figure 9 The diagram illustrates the clamping head 901 of the clamping structure. Both semi-circular free ends of the clamping head 901 are equipped with fixing components. Fastening bolts are threadedly connected to the two fixing components. A drive motor 902 is located at one end of the fastening bolt, which rotates the fastening bolt. In use, a cylindrical rod is inserted into the clamping head 901, and then the drive motor 902 actuates, causing the clamping head 901 to clamp the cylindrical rod (of course, the drive motor 902 can be reversed to release the cylindrical rod). Adding a penetration module 9 releases the cylindrical rod to impact the container downwards, simulating the stress changes when the container is penetrated.

[0031] Regarding height position adjustment structure 3, see [link / reference]. Figures 2-5The height adjustment structure 3 includes a frame 301, a height drive motor 302, and a belt pulley structure. The frame 301 includes two relatively parallel and spaced vertical plates. The drive wheel 303 and driven wheel 304 of the belt pulley structure are spaced vertically. The drive wheel 303 is connected to the height drive motor 302. (See attached image) Figure 3 The diagram illustrates the height drive motor 302, which, along with the drive wheel 303 and driven wheel 304, is supported on the frame 301. (See attached diagram.) Figure 5 The diagram illustrates the driving wheel 303 and the driven wheel 304; the horizontal position adjustment structure 4 is connected to the belt 305 of the belt pulley structure via the intermediate connecting structure 10; see also... Figure 4 The intermediate connecting structure 10 includes a first connecting plate 1001 and a second connecting plate 1002. The first connecting plate 1001 is engaged with the vertical guide rail of the frame 301 (a slider is provided on the first connecting plate 1001, and the slider is engaged with the vertical guide rail of the frame 301). The first connecting plate 1001 is connected to the horizontal position adjustment structure 4. The second connecting plate 1002 is detachably connected to the first connecting plate 1001 and a belt 305 is sandwiched between the two.

[0032] When the height drive motor 302 is activated, the drive wheel 303 rotates, which in turn drives the belt to move. Since the horizontal position adjustment structure 4 is fixed on the belt 305 through the intermediate connection structure 10, it can drive the horizontal position adjustment structure 4 to move along the height direction.

[0033] Regarding the intermediate connecting structure 10, two can be arranged opposite each other. The frame 301 includes two vertical plates arranged parallel to each other. One intermediate connecting structure 10 is engaged with one vertical plate of the frame 301 via a slider rail, and the other intermediate connecting structure 10 is engaged with the other vertical plate of the frame 301 via a slider rail. However, one of the intermediate connecting structures 10 is tightly engaged with the belt 305, so that it follows the belt 305 when it moves; the second connecting plate 1002 of the other intermediate connecting structure 10 is not clamped to the first connecting plate 1001.

[0034] See Figure 6 The diagram illustrates two L-shaped limiting members 306, which are fixed to the two vertical plates of the frame 301. Each limiting member 306 is equipped with a vertical screw. When the horizontal position adjustment structure 4 rises under the drive of the belt, if the first connecting plate 1001 of the intermediate connecting structure 10 contacts the vertical screw on the limiting member 306, the horizontal position adjustment structure 4 can be restricted from continuing to move upward.

[0035] Regarding the horizontal position adjustment structure 4, see [link / reference]. Figure 7The horizontal position adjustment structure 4 includes a horizontal drive motor 401, an intermediate transmission mechanism, and a lead screw mechanism 402. The intermediate transmission mechanism is a conveyor belt structure. The horizontal drive motor 401 is connected to the driving wheel of the intermediate transmission mechanism, and the driven wheel of the horizontal drive motor 401 is connected to the lead screw of the lead screw mechanism 402. The slider of the lead screw mechanism 402 is connected to the rotating structure 5. When the horizontal position adjustment structure 4 is activated, the conveyor belt structure drives the lead screw to rotate, thereby causing the slider of the lead screw mechanism 402 to move along the axial direction of the lead screw. Since the rotating structure 5 is connected to the slider, it can move horizontally.

[0036] Regarding rotational structure 5, see [link / reference]. Figure 7 and Figure 8 The rotating structure 5 includes a rotating drive structure, a first rotating support frame 501, a second rotating support frame 502, a rotating flange shaft 503, and an angle limiting structure 504. The first rotating support frame 501 is connected to the horizontal position adjustment structure 4. The second rotating support frame 502 is equipped with a rotating drive structure. The drive shaft of the rotating drive structure is connected to one end of the rotating flange shaft 503. The other end of the rotating flange shaft 503 is rotatably supported on the first rotating support frame 501. The clamp assembly 6 is connected to the second rotating support frame 502. The angle limiting structure 504 is set on the rotating flange shaft 503. The angle limiting structure 504 is a clamp structure, and a horizontal screw 505 is threadedly connected to the angle limiting structure 504. One end of the horizontal screw 505 is used to abut against the first rotating support frame 501.

[0037] When adjusting the angle, first loosen the horizontal screw 505. The rotation drive structure will drive the second rotation support frame 502 and the clamp assembly 6 to rotate. When the angle is rotated to the correct position, the rotation drive structure stops. Then, the operator manually tightens the horizontal screw 505 so that it abuts against the first rotation support frame 501, which locks the position of the rotating flange shaft 503 and prevents the rotating flange shaft 503 from rotating.

[0038] For "Clamp Assembly 6", see Figure 7 The clamp assembly 6 includes a clamp frame 601, magnetic chucks 602, and chuck position driving structures. The clamp frame 601 is connected to the rotating structure 5. There are two magnetic chucks 602, each connected to a corresponding chuck position driving structure. The two chuck position driving structures are used to adjust the distance between the two magnetic chucks 602. This invention uses a mechanical clamp combined with magnetic attraction, making it suitable for cylindrical containers.

[0039] Regarding the suction cup position drive structure, the suction cup position drive structure includes a suction cup slider 603 and a linear drive structure. The suction cup slider 603 cooperates with the slide rail on the fixture frame 601, and the linear drive structure is connected to the suction cup slider 603 to drive the suction cup slider 603 to move.

[0040] See Figure 7 The diagram illustrates the suction cup slider 603, which is connected to the corresponding magnetic suction cup 602 via a connecting rod. The suction cup slider 603 cooperates with the slide rail on the fixture frame 601. The linear drive structure of the suction cup position drive structure can be a lead screw mechanism, or it can be a drive motor + transmission belt structure, similar in principle to the height position adjustment structure.

[0041] A method for stress testing using an apparatus for drop stress testing of radioactive containers, comprising the following: The container to be tested is fixed on the clamp assembly 6 of the device; Adjust the angle of the container and install strain gauges on the container; Raise the container to the specified height; Move the container above the contact surface base 7; Control clamp assembly 6 to release the container; Remove the strain gauge, connect it, and record the collected data.

[0042] By adding a data acquisition element (strain gauge) to the container, which uses the principle of variable resistance, the data on the internal stress changes of the container during the drop can be collected. This data can intuitively reflect the stress changes at a certain part of the container during the drop. The collected data can be combined with the simulation results for analysis and mutual verification, which can facilitate the design or improvement of its structure to meet the requirements of various mechanical properties.
