Description

Technical Field

[0001] The invention relates to the field of X-ray industrial product quality inspection equipment, and in particular to a cantilever telescopic platform CT / DR dual-mode inspection system. Background Art

[0002] DR detection is direct radiography of workpieces. Its principle is that X-rays will interact with materials during the process of penetrating objects, and their intensity will be attenuated due to absorption and scattering. The degree of intensity attenuation is related to the attenuation coefficient of the material and the thickness of the rays passing through the material. If there are defects in a part of the irradiated object, and the attenuation coefficient of the material constituting the defect is different from that of the main structure, the intensity of the transmitted rays in this local area will be different from that of the surrounding area. By processing the difference, the corresponding image is generated.

[0003] CT is an inspection technology that uses X-rays to penetrate the human body and uses detectors to receive signals to form images. The basic principle of CT imaging is to use an X-ray beam to scan a layer of a certain thickness of the human body to be inspected. The detector receives the X-rays that pass through the layer, converts them into visible light, and then converts them into electrical signals by a photoelectric converter. Then, they are converted into digital signals by an analog / digital converter and input into a computer for processing.

[0004] Regardless of whether it is DR detection or CT detection, both use X-rays in the detection process, which will cause radiation hazards to the human body. Therefore, in response to this problem, one of the solutions proposed by existing equipment is to extend the transmission distance so that the operator can be as far away from the detection center as possible. However, on the one hand, the traditional extension rack is not highly compatible with the equipment and is prone to mechanical interference during transportation. On the other hand, in order to ensure good support performance, its cost is high. Therefore, it is necessary to propose a solution that reduces costs and increases efficiency and can ensure the safety of technical personnel during construction.

[0005] The invention patent with Chinese patent application number 202311636517.5 discloses an X-ray protection device, which comprises: a protective lead plate component for protecting against X-rays; a double counterweight transverse movement structure, wherein the output end of the double counterweight transverse movement structure is connected to the output end of the protective lead plate component, and is used to drive the output end of the protective lead plate component to move laterally quickly; the double counterweight transverse movement structure comprises a first counterweight component and a second counterweight component, wherein the first counterweight component drives the output end of the protective lead plate component to move laterally, the force applied by the first counterweight component to the output end of the protective lead plate component is stable, and the output end of the protective lead plate component starts to move laterally at a uniform acceleration from zero speed, and when it reaches half of the stroke, the second counterweight component applies force to the protective A reverse force is applied to the output end of the lead plate component to reduce the speed of the output end of the protective lead plate component, so that the output end of the protective lead plate component performs a uniform deceleration motion until the speed is zero, thereby realizing fast and stable driving of the protective lead plate and avoiding collision and sound at the end of the stroke. The technical solution adopted by the above invention is essentially to use lead plates for radiation protection and is mainly used in the medical field. The quality inspection of industrial products in industry is different from that in the medical field. The professional awareness of technical personnel themselves is not as strong as that of medical staff. Secondly, the inspection volume of industrial products is large, and there are many repeated cycle processes. At the same time, the amount of radiation in industrial inspection is greater than that in the medical field, so it needs more attention. Summary of the invention

[0006] Therefore, in response to the above problems, the present invention proposes a cantilever telescopic platform CT / DR dual-mode detection system, which solves the technical problems of the existing industrial product inspection and transportation process that multi-angle and multi-directional scanning inspection cannot be carried out and the functionality is single. At the same time, it optimizes the disadvantage that the existing industrial product quality inspection process through X-ray inspection is easy to endanger operators due to X-ray radiation.

[0007] To achieve the above object, the present invention adopts the following technical scheme: a cantilever telescopic platform CT / DR dual-mode detection system, comprising a frame, a detection cabin fixedly arranged on the frame, a first detection material door and a second detection material door arranged on the detection cabin, a CT detection mechanism and a DR detection mechanism arranged in the detection cabin, the CT detection mechanism feeds through the first detection material door, the DR detection mechanism feeds through the second detection material door, and a main transmission track is arranged on the inner top surface of the detection cabin; The CT detection mechanism includes a detection plate group slidably arranged on the main transmission track, a support platform fixedly arranged on the detection cabin, and a rotating disk assembly movably arranged on the support platform, the detection plate group includes two detection plates arranged opposite to each other, and an X-ray emitter is arranged on the detection plate; The DR detection mechanism includes a working platform arranged at the bottom of the detection cabin, a first auxiliary transmission track arranged on the working platform, a mouth-shaped frame arranged on the main transmission track, and an X-ray emitter suspended on the mouth-shaped frame, the first auxiliary transmission track is provided with a transport conveyor belt for supporting industrial products, the mouth-shaped frame can move back and forth along the length direction of the main transmission track, the working platform forms a gap with the lower bottom surface of the detection cabin through the supporting feet, and the mouth-shaped frame passes through the gap to completely surround the working platform to form a closed loop; The first auxiliary transmission track is directly opposite to the second material detection door, the work platform is provided with an extended cantilever system for placing industrial products, the first material detection door is provided with a movable sliding protective door, and the second material detection door is provided with a lifting protective door.

[0008] Furthermore, a second secondary transmission track is arranged on the supporting platform, and the arrangement direction of the second secondary transmission track is perpendicular to the transmission direction of the main transmission track. The rotating disk assembly includes a sliding base, a rotating disk arranged on the sliding base, and a fixed claw arranged on the top surface of the rotating disk. The sliding base cooperates with the second secondary transmission track and moves back and forth along the length direction of the second secondary transmission track. The rotating disk can rotate 360° along its central axis.

[0009] Furthermore, a plurality of clamping tracks are arranged on the upper top surface of the rotating disk, and each of the clamping tracks radially spreads out to the edge of the rotating disk with the center of the rotating disk as the origin. The fixed clamping claws are movably arranged on the clamping tracks, and the industrial products are clamped by moving on the clamping tracks to approach or move away from the center of the rotating disk, and the movements of each of the fixed clamping claws are independent of each other.

[0010] Furthermore, the two detection plates operate independently of each other and can be moved closer to or farther away from each other to adapt to the industrial products on the rotating disk.

[0011] Furthermore, the extended cantilever system is arranged on one end of the working platform close to the second material detection door, and the extended cantilever system includes a fixed base, a first rocker, a second rocker, a third rocker and a supporting cantilever respectively arranged on both side surfaces of the working platform, the fixed base is rotatably connected to the working platform, a movable slide groove is arranged in the fixed base, and the supporting cantilever is movably arranged in the movable slide groove, extending outward or retracting inward along the trajectory defined by the movable slide groove, and when the supporting cantilever is extended outward to the end of the stroke, the end of the supporting cantilever exposed from the second material detection door is a distance The distance is 0.8m-1.2m; the first rocker arm and the fixed base are rotatably connected, one end of the second rocker arm is rotatably connected to the first rocker arm, and the other end is rotatably connected to the third rocker arm, one end of the third rocker arm is rotatably connected to the second rocker arm, and the other end is rotatably connected to the supporting cantilever, the first rocker arm is driven to rotate by a built-in rotating motor, and the rotating motor can rotate forward or reverse, thereby driving the supporting cantilever to extend outward or retract inward in a rotating transmission manner, and a supporting plate is placed between the two supporting cantilevers, and the height of the supporting plate is higher than the transport conveyor belt.

[0012] Furthermore, the second rocker is provided with a limiting slide groove for shortening its swing stroke, and the end of the first rocker is embedded in the limiting slide groove on the second rocker, and rotates and moves synchronously in the limiting slide groove during the rotation drive process.

[0013] Furthermore, the extended cantilever system is provided with an auxiliary stabilizing mechanism for ensuring the stability of the supporting cantilever when it is extended outward to support industrial products.

[0014] Furthermore, the auxiliary stabilizing mechanism includes an auxiliary positioning rod mounted between the two second rocking arms and a stabilizing top block disposed on the auxiliary positioning rod close to one side of the supporting cantilever.

[0015] Furthermore, a movable saddle is provided on the first secondary transmission track, and the movable saddle is mounted on the first secondary transmission track and moves back and forth along the length direction of the first secondary transmission track.

[0016] Furthermore, the working platform is provided with an induction switch for controlling the CT detection mechanism to start or stop working. The induction switch is arranged on the side of the working platform and is located in the middle position in the length direction of the working platform. The CT detection mechanism is turned on or off by sensing the movement of the mouth frame.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are: 1. The cantilever telescopic platform CT / DR dual-mode detection system proposed in the present invention can perform CT detection or DR detection on industrial products in the same device, ensuring the comprehensiveness of industrial product detection and avoiding the technical problem that the existing industrial products are easily endangered by radiation during the quality detection process of radiation. The specific improvement is: by combining the CT detection mechanism and the DR detection mechanism, the equipment's floor space is simplified. At the same time, both CT detection and DR detection will release radioactive rays during work, and if no protective measures are taken, the safety of the operators will be endangered. If separate equipment is used for detection, the frequent transfer of industrial products between the two devices will increase the risk of radiation. The CT detection mechanism in the present invention is mainly through a detection plate group and a support table, wherein the support table is used to place industrial products, and the detection plate group is used to perform CT detection on the industrial products on the support tray. The two inspection plates in the inspection plate group can move independently, approaching or moving away from each other, in order to adapt to industrial products of different specifications. The approaching or moving away from each other can ensure that the two inspection plates maintain a suitable inspection distance from the industrial products. The DR inspection mechanism mainly detects the industrial products through the cooperation of the transport conveyor belt on the first secondary transmission track and the X-ray emitter on the mouth frame. The transport directions of the transport conveyor belt and the mouth frame are opposite, that is, the industrial products on the transport conveyor belt and the mouth frame are ensured to work in a state close to each other, which improves the work efficiency. The first inspection material door and the second inspection material door are respectively provided with movable sliding protection doors and lifting protection doors, in order to further improve the overall protection performance of the system and completely eliminate the risks brought by X-ray radiation. The movable sliding protection doors and lifting protection doors are both lead doors. The traditional industrial product flaw detection system generally adopts a lead curtain arranged above the conveyor belt to protect against radiation. At that time, the lead curtain is easy to exert force on the industrial products when the industrial products pass by due to its own heavy characteristics, causing the industrial products to tip over or shift.

[0018] 2. In the CT detection mechanism of the present invention, industrial products are transported by the sliding base on the second auxiliary transmission track. The rotating disk on the sliding base is used to rotate synchronously during the detection process of the industrial products, ensuring that the industrial products on the rotating disk rotate 360° along the central axis of the rotating disk, thereby ensuring that the industrial products can be fully displayed in the plane space formed by the two detection plates for quality detection.

[0019] 3. In the present invention, a clamping track is provided on the rotating disk, and a plurality of fixed claws are provided on the clamping track. At the same time, each fixed claw can move independently on the corresponding clamping track, close to the center of the rotating disk or away from the center of the rotating disk, so as to meet the clamping requirements of industrial products of different specifications.

[0020] 4. The present invention is provided with an extendable cantilever system to greatly improve the convenience and safety of use of the present invention. The convenience is reflected in that in traditional industrial product detection devices, if you want to extend the distance between the operator and the ray emitter, usually you add a conveyor belt for transmission, which requires adding an additional conveying mechanism. Adding an additional conveying mechanism increases the cost on the one hand, and on the other hand, it is necessary to ensure that the added conveying mechanism and the main conveying mechanism have a satisfactory degree of coordination. At the same time, the added conveying mechanism also directly increases the overall footprint of the equipment, which occupies multiple resources. The present invention directly provides an extendable cantilever system in the DR detection mechanism in the detection cabin, so that when in use, the supporting cantilever is extended outward by a suitable distance to support and transport the industrial products to be detected, and after completing the industrial product receiving operation, it retracts inward to transfer the industrial products from the support plate to the transport conveyor belt for industrial product detection.

[0021] 5. In the present invention, a limited sliding groove is provided on the second rocker to shorten the swing stroke between the first rocker and the second rocker.

[0022] 6. The present invention further provides an auxiliary stabilizing mechanism on the extended cantilever system for ensuring that the supporting cantilever provides supporting stability for the industrial product when it is extended outward, ensuring that the auxiliary stabilizing mechanism directly rests downward against the initial end of the supporting plate when the supporting cantilever is extended outward, while the force of the industrial product is at the free end of the supporting plate, providing it with good supporting stability performance through the lever principle.

[0023] 7. The present invention is provided with a movable saddle, and the function of the movable saddle is to spread the industrial products that may be piled up on the transport conveyor belt through its own back and forth movement.

[0024] 8. The present invention ensures the rationality and safety of the system operation by providing an induction switch. If the CT detection system and the DR detection system are turned on at the same time and X-rays are emitted at the same time, the radiation of the two will be superimposed on each other, so they need to work separately. By adding an induction switch, it can be directly coordinated with the stroke of the mouth frame, that is, the reciprocating motion and position of the mouth frame can be used to determine whether the DR detection mechanism is in a working state, thereby controlling the start and stop of the CT detection mechanism.
