Description

Technical Field

[0001] This utility model relates to the field of CT equipment technology, specifically to a CT equipment bed anti-fall device. Background Technology

[0002] CT system beds are equipped with linear motion systems that reciprocate. A device is needed between the bed sample delivery rod and the outer casing to prevent samples from falling during loading, or to facilitate removal if they do fall, without affecting the bed's reciprocating motion. A common device is an accordion cover installed on the outer casing, with one end connected to the outer casing and the other end connected to the motion system slider. When samples fall, they land on the accordion cover and need to be removed. However, the accordion cover has disadvantages: it is compressed when the motion system reaches its extreme positions, taking up space; additionally, when the accordion cover contracts during linear motion, it comes into contact with the outer casing, which can easily produce abnormal noises.

[0003] In light of this, we have developed a device to prevent CT equipment beds from falling off. Utility Model Content

[0004] The purpose of this invention is to provide a CT equipment bed anti-fall device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CT equipment bed anti-fall device, comprising: a frame and a sample delivery rod connecting plate; The top of the frame is equipped with a bed system upper panel, the top of the bed system upper panel is equipped with a lower bed linear motion system, the top of the lower bed linear motion system is slidably connected to an upper linear motion system slider, and the top of the upper linear motion system slider is equipped with an upper bed linear motion system. The sample feeding rod connecting plate is set on the top of the upper bed linear motion system, and the top of the sample feeding rod connecting plate is connected to the sample feeding adapter plate. The top of the sample transfer plate is equipped with a receiving mechanism. Through the cooperation of the end roller, front roller and conveyor belt of the receiving mechanism, when something falls from the animal cabin, the conveyor belt will catch the falling object and make it easy to retrieve.

[0006] Preferably, the receiving mechanism includes a CT side roller bracket connected to one side of the upper panel of the bed system, and a bed end roller bracket provided on the other side of the surface of the upper panel of the bed system. The bed end roller is connected to the inner side of the bed end roller bracket, and the bed front roller is connected to the inner side of the CT side roller bracket. The conveyor belt is sleeved between the bed end roller and the bed front roller. Both the CT side roller bracket and the bed end roller bracket are welded from angle steel and have sufficient support strength. They are symmetrically installed on both sides of the upper panel of the bed system to ensure that the axes of the bed end roller and the bed front roller remain parallel, and to avoid deviation or jamming of the conveyor belt during operation.

[0007] Preferably, the conveyor belt is fixed to the surface of the sample transfer plate by screws, and a sample transfer rod connecting seat is connected to the top of the sample transfer plate. A sample transfer rod is connected to one side of the top of the sample transfer rod connecting seat, and an animal compartment is provided on one side of the sample transfer rod. The screws that fix the conveyor belt adopt an internal hexagon countersunk head design to avoid scratching the conveyor belt or dropping items from the protruding surface. The sample transfer rod connecting seat has an L-shaped structure and is rigidly connected to the sample transfer plate by welding. It can stably bear the weight of the sample transfer rod and the animal compartment, and ensure the positional accuracy of the animal compartment when it moves synchronously with the sample transfer plate.

[0008] Preferably, the side of the end roller bracket of the bed has a housing gap, and the side of the end roller bracket of the bed is connected to a groove of the bed housing. The width of the housing gap is 13mm, which can prevent the end roller bracket of the bed from colliding with the bed housing of the CT equipment during movement. The groove of the bed housing has a U-shaped structure with the opening facing upward, which can form a barrier on the top of the conveyor belt to prevent falling items from being ejected from the edge of the conveyor belt and improve the reliability of the receiving.

[0009] Preferably, the top of the conveyor belt is provided with a conveyor belt top section, and the bottom of the conveyor belt is connected to a conveyor belt bottom section. The conveyor belt top section is a working surface that directly receives dropped items, and the surface is treated with anti-slip treatment to prevent items from sliding after being received. The conveyor belt bottom section is attached to the upper surface of the sample feeding rod connecting plate. With the support of the sample feeding rod connecting plate, the conveyor belt is prevented from sagging due to its own weight or the weight of the items it receives, thus ensuring the flatness of the conveyor belt.

[0010] Preferably, a testing frame is connected to the side of the frame, and a mounting plate is connected to the surface of the testing frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) The conveyor belt of the receiving mechanism and the sample transfer plate form a "movement community". It unfolds or retracts synchronously with the displacement of the sample transfer plate and is always in the "protected area" directly below the animal cabin. At the same time, the conveyor belt passes through the 13mm gap between the sample rod connecting plate and the sample transfer plate and is embedded in the groove of the bed shell at the top. This avoids friction with other parts and prevents dropped items from popping out through the enclosure structure of the groove of the bed shell. No matter where the animal cabin is in the detection path, the conveyor belt can achieve "no dead angle" reception, eliminating the problem of loss or contamination caused by test samples, auxiliary tools and other items falling into the equipment. This reduces material loss and equipment maintenance costs during the detection process. (2) By using the bed movement program of the CT equipment, the sample transfer plate is moved to a position that is easy to operate, such as the outside of the equipment. The conveyor belt will extend synchronously with the sample transfer plate. The items can be picked up directly from above the conveyor belt. The whole process of picking up the items is short and simple to operate. It does not require interruption of the core operation process of the CT equipment. It is especially suitable for batch sample detection scenarios, effectively reducing the detection interruption time caused by picking up the items, greatly improving the overall detection efficiency, and reducing the workload of the operators.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0016] Please see Figure 1-8 This utility model provides a technical solution: a CT equipment bed anti-fall device, including: a frame 18, a bed system upper panel 9 is provided on the top of the frame 18, a lower bed linear motion system 8 is provided on the top of the bed system upper panel 9, an upper linear motion system slider is slidably connected to the top of the lower bed linear motion system 8, and an upper bed linear motion system 7 is provided on the top of the upper linear motion system slider. Sample feeding rod connecting plate 6 is set on top of upper bed linear motion system 7, and sample feeding adapter plate 4 is connected to the top of sample feeding rod connecting plate 6; The top of the sample transfer plate 4 is equipped with a receiving mechanism. Through the cooperation of the bed end roller 11, bed front roller 12 and conveyor belt 13 of the receiving mechanism, when something falls from the animal cabin, the conveyor belt 13 will catch the falling thing and make it easy to take it out.

[0017] The receiving mechanism includes a CT side roller bracket 10 connected to one side of the upper panel 9 of the bed system. It is made of angle steel and has sufficient support strength to fix the front roller of the bed. On the other side of the surface of the upper panel 9 of the bed system, there is a bed end roller bracket 5. The structure is symmetrical with the CT side roller bracket 10, which facilitates subsequent roller maintenance and replacement. The bed end roller 11 is connected to the inner side of the bed end roller bracket 5, and the bed front roller 12 is connected to the inner side of the CT side roller bracket 10. The conveyor belt 13 is sleeved between the bed end roller 11 and the bed front roller 12. The tension of the conveyor belt 13 can be adjusted by adjusting the installation position of the bed end roller bracket 5 to avoid the conveyor belt 13 becoming loose and affecting the receiving effect.

[0018] The conveyor belt 13 is fixed to the surface of the sample transfer plate 4 by screws. The screws are designed with countersunk hexagonal heads to prevent them from protruding and scratching the conveyor belt 13 or causing items to fall. The top of the sample transfer plate 4 is connected to the sample transfer rod connector 3. The top side of the sample transfer rod connector 3 is connected to the sample transfer rod 2. The side of the sample transfer rod 2 is provided with an animal chamber 1. The animal chamber 1 is used to place the animal to be tested. The chamber is made of X-ray resistant material so as not to affect the CT test results.

[0019] The side of the end roller bracket 5 of the bed is provided with a housing gap 14, the gap width of which is 13mm, to avoid collision and friction between the end roller bracket of the bed and the bed housing during movement. The side of the end roller bracket 5 is connected to the bed housing groove 17.

[0020] The top of the conveyor belt 13 is provided with a conveyor belt top 15, the surface of which is kept flat and clean to avoid affecting the receiving of items due to protrusions or stains. The bottom of the conveyor belt 13 is connected to a conveyor belt bottom 16, which is supported by a sample transfer plate 4 to prevent the conveyor belt from sagging due to its own weight or the weight of the items it is carrying.

[0021] The side of the frame 18 is connected to a test frame 19, which is made of square steel welded together. Its height matches that of the frame 18 and can be used as a mounting carrier for auxiliary test components. The surface of the test frame 19 is connected to a mounting plate 20.

[0022] Specifically, during use, the frame 18 serves as the supporting foundation for the entire device. The upper panel 9 of the bed system fixed at its top provides a stable installation platform for the lower bed linear motion system 8. When the CT equipment starts the bed motion program, the motor drives the lower bed linear motion system 8 to operate. This system, through the built-in guide rail and slider structure, drives the "upper linear motion system slider" slidable at the top to perform a first-dimensional linear reciprocating motion (usually a back-and-forth movement along the CT equipment axis). The upper bed linear motion system 7 fixed at the top of the linear motion system slider will, under its own motor drive, drive the sample delivery rod connecting plate 6 at the top to perform a second-dimensional linear motion (which can be adjusted to a lateral or fine-tuning motion according to the detection requirements), forming a composite motion mode of "dual linear motion system coordination". Ultimately, it achieves the precise displacement of all components at the top of the sample delivery rod connecting plate 6 (including the sample delivery adapter plate, the receiving mechanism, and the animal cabin), meeting the positioning and detection requirements of the CT equipment for the animal cabin 1. The sample delivery rod connecting plate 6 and the sample delivery adapter plate 4 are fixedly connected by bolts, with a specific gap of 13mm (i.e., the outer shell gap 14) reserved between them. This gap provides space for the subsequent passage of the conveyor belt 13. The sample delivery rod connecting seat 3 on the top of the sample delivery adapter plate 4 is fixed by welding or screws, which rigidly connects the sample delivery rod 2 and the sample delivery adapter plate 4. Ultimately, the animal cabin 1 (installed at the front end of the sample delivery rod 2) moves synchronously with the movement of the sample delivery adapter plate 4, ensuring the positional accuracy of the animal cabin during the detection process. The fixed ends of the receiving mechanism are anchored on both sides of the upper panel 9 of the bed system. One side is fixed to the front roller 12 of the bed through the CT side roller bracket 10, and the other side is fixed to the end roller 11 of the bed through the end roller bracket 5. The axes of the two rollers are kept parallel to ensure that the conveyor belt 13 can be stably fitted to form a closed loop structure. The two ends of the conveyor belt 13 are fixed to the front and rear ends of the sample transfer plate 4 by screws (the front end is close to the CT side roller bracket, and the rear end is close to the end roller bracket of the bed). This fixing method makes the conveyor belt 13 and the sample transfer plate 4 form a "movement community". When the sample transfer plate 4 moves back and forth with the linear motion system 7 of the upper bed, it will synchronously pull the conveyor belt 13 to slide along the outer periphery of the front roller 12 and the end roller 11 of the bed, realizing the dynamic deployment and retraction of the conveyor belt 13. During its movement, the conveyor belt 13 passes through the 13mm gap 14 between the sample delivery rod connecting plate 6 and the sample delivery adapter plate 4. At the same time, its top (above the conveyor belt 15) is located in the groove 17 of the bed housing (the groove 17 of the bed housing on the side of the bed end roller bracket 5 matches the gap 14). This spatial design avoids friction between the conveyor belt 13 and other components (such as the sample delivery rod connecting plate and the bed housing) and ensures that the conveyor belt 13 is always in the "protected area" directly below the animal cabin 1, forming a complete drop receiving surface. Since the conveyor belt 13 is always directly below the animal compartment 1 (moving synchronously with the sample transfer plate 4), when an item falls, it will land directly on the surface of the conveyor belt 15. The enclosure structure of the bed shell groove 17 can prevent the item from popping out from the edge of the conveyor belt, ensuring that the fallen item is completely confined on the conveyor belt (13). When the detection is paused or an item is found to have fallen, the sample transfer plate 4 can be moved to a position that is easy to operate (such as outside the equipment) by controlling the bed movement program of the CT equipment. At this time, the conveyor belt 13 extends synchronously with the sample transfer plate 4. The operator can pick up the fallen item directly from the conveyor belt 15 without disassembling the device or going into the equipment. The whole process does not require interrupting the core operation of the equipment, which greatly improves the operating efficiency. After the sample is retrieved, when the sample transfer plate 4 is reset, the conveyor belt 13 will be retracted and repositioned between the two rollers, restoring the initial protective state and ensuring that the anti-drop function remains effective during subsequent testing.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
