Detailed implementation mode

[0042] The following will specifically describe the preferred embodiments of the present invention in conjunction with the accompanying drawings. Among them, the accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principle of the present invention, rather than to limit the scope of the present invention.

[0043] Embodiment 1

[0044] A specific embodiment of the present invention discloses a multi - synchronous - belt parallel conveying platform system for CT detection, as Figure 1 、 Figure 2 shown, including: a conveyor frame 1, parallel conveyor belts 2, driven synchronous pulleys 6 and a driving mechanism 4; the driven synchronous pulleys 6 are rotatably installed on the conveyor frame 1, and two are provided at both ends of the conveyor frame 1; the parallel conveyor belts 2 are annular synchronous belts; a plurality of the parallel conveyor belts 2 are arranged in parallel, and all the plurality of parallel conveyor belts 2 are sleeved outside the driven synchronous pulleys 6 and can rotate under the drive of the driving mechanism; when the parallel conveyor belts 2 rotate, the conveying of workpieces can be realized. In this embodiment, the transmission of a maximum 5 - ton load for CT detection can be solved.

[0045] Specifically, a plurality of meshing teeth arranged in an annular shape are provided on the inner side of the parallel conveyor belt 2.

[0046] In a specific implementation manner of the present invention, as Figure 3 、 Figure 4 shown, the driving mechanism includes: a driving synchronous pulley 7; the driving synchronous pulley 7 meshes with a plurality of the parallel conveyor belts 2 and can drive the parallel conveyor belts 2 to rotate. In this embodiment, by the driving synchronous pulley 7 meshing with a plurality of parallel conveyor belts 2 at the same time, the technology of driving multiple synchronous belts with one power output is realized.

[0047] Furthermore, as Figure 3 、 Figure 4As shown, the drive mechanism 4 further includes: a drive synchronous pulley 13, a drive motor 8, a motor shaft end synchronous pulley 9, and a drive synchronous belt 10; the output shaft of the drive motor 8 is fixedly connected to the motor shaft end synchronous pulley 9; the drive synchronous belt 10 is sleeved outside the drive synchronous pulley 13 and the motor shaft end synchronous pulley 9; when the drive motor 8 drives the motor shaft end synchronous pulley 9 to rotate, the drive synchronous belt 10 drives the drive synchronous pulley 13 to rotate.

[0048] Specifically, the drive synchronous pulley 13 is fixedly connected to the driving synchronous pulley 7 and the two can rotate synchronously. The driving synchronous pulley 7 is rotatably mounted on the conveying frame 1 through a driving wheel shaft 21.

[0049] Specifically, as Figure 4 , Figure 5 shown, the drive motor 8 and the drive synchronous pulley 13 are respectively fixed on the conveying frame 1 through a motor bracket 11 and a synchronous pulley bracket 12, and the motor shaft end synchronous pulley 9 is fixedly installed on the power output shaft of the drive motor 8.

[0050] In this embodiment, the drive mechanism 4 is composed of a drive motor 8, a motor shaft end synchronous pulley 9, a drive synchronous belt 10, a motor bracket 11, a synchronous pulley bracket 12, a drive synchronous pulley 13, and a synchronous belt supporting pulley 14. When the output shaft of the drive motor 8 rotates, the drive motor 8 drives the motor shaft end synchronous pulley 9 to rotate and transmits the torque to the drive synchronous pulley 13 through the drive synchronous belt 10, driving the drive synchronous pulley 13 and the driving synchronous pulley 7 to rotate; when the driving synchronous pulley 7 rotates, it can drive the parallel conveyor belt 2 to rotate to realize workpiece conveying.

[0051] Furthermore, to ensure that more teeth of the parallel conveyor belt 2 are engaged with the driving synchronous pulley 7 and to ensure the stability of force transmission, two synchronous belt supporting pulleys 14 are used to support the outer surface of the parallel conveyor belt 2, so that the inner surface of the parallel conveyor belt 2 wraps around the driving synchronous pulley 7, promoting the driving effect of the driving synchronous pulley 7 on the parallel conveyor belt 2 and realizing synchronous movement between the driving synchronous pulley 7 and the parallel conveyor belt 2.

[0052] As Figure 5 shown, the conveying frame 1 is rotatably installed with a first synchronous belt supporting pulley 14 and a second synchronous belt supporting pulley 20. Specifically, the driving synchronous pulley 7 is arranged inside the parallel conveyor belt 2; the first synchronous belt supporting pulley 14 and the second synchronous belt supporting pulley 20 are arranged outside the parallel conveyor belt 2.

[0053] Further, the heights of the first synchronous belt supporting pulley 14 and the second synchronous belt supporting pulley 20 are higher than the height of the driving synchronous belt pulley 7. Specifically, the distance between the first synchronous belt supporting pulley 14 and the second synchronous belt supporting pulley 20 is less than the shaft diameter of the driving synchronous belt pulley 7; the meshing wrap angle between the driving synchronous belt pulley 7 and the parallel conveyor belt 2 is an obtuse angle.

[0054] In a specific embodiment of the present invention, as Figure 6 shown, a tensioning mechanism 3 is further installed on the conveyor frame 1; the tensioning mechanism 3 includes: a tensioning pulley 15, a tensioning pulley bracket 16, and a tensioning pulley adjusting rod 17; the tensioning pulley 15 is rotatably installed on the tensioning pulley bracket 16; the upper end of the tensioning pulley adjusting rod 17 is threadedly connected to the conveyor frame 1, and the lower end of the tensioning pulley adjusting rod 17 is rotatably connected to the tensioning pulley bracket 16 through a bearing; rotating the tensioning pulley adjusting rod 17 to adjust its installation position on the conveyor frame 1 can adjust the height of the tensioning pulley 15, thereby realizing the tensioning of the parallel conveyor belt 2.

[0055] Specifically, the number of the tensioning mechanisms 3 is equal to the number of the parallel conveyor belts 2; each group of tensioning mechanisms 3 independently tensions one parallel conveyor belt 2. In this embodiment, multiple parallel conveyor belts 2 are respectively provided with independent tensioning mechanisms 3, the tensioning pulley 15 meshes with the internal teeth of the parallel conveyor belt 2, and the tensioning pulley 15 presses down on the parallel conveyor belt 2. By adjusting the height of the tensioning pulley 15, the tensioning of the parallel conveyor belt 2 is realized.

[0056] In a specific embodiment of the present invention, as Figure 7 shown, multiple groups of leveling mechanisms 5 are installed at the bottom of the conveyor frame 1.

[0057] As Figure 7 shown, the leveling mechanism 5 includes: an adjusting foot 18 and a locking nut 19; specifically, the adjusting foot 18 is threadedly connected to the threaded hole at the bottom of the conveyor frame 1; and a locking nut 19 is threadedly sleeved on the adjusting foot 18; during implementation, rotating the adjusting foot 18 can adjust the length of the adjusting foot 18 extending out of the conveyor frame 1, and then rotating the locking nut 19 to make it abut against the bottom of the conveyor frame 1, thereby supporting the conveyor frame 1 through the leveling mechanism 5. In this embodiment, the leveling mechanism 5 is installed on the conveyor frame 1. When it is measured that the conveyor frame 1 is not parallel to the ground, loosen the locking nut 19, and use a tool to rotate the adjusting foot 18 to adjust the height of the adjusting foot 18. When the horizontal requirement is met, tighten the locking nut 19 to realize the leveling of the conveyor frame 1.

[0058] The multi-synchronous belt parallel transmission platform system for CT detection in this embodiment realizes the adjustability of the height and parallelism of the transmission platform by installing adjusting feet 18 and locking nuts 19 at the bottom of the conveying frame 1.

[0059] The multi-synchronous belt parallel transmission platform system of the present invention is mainly aimed at the transmission process of workpieces from the feeding position through the imaging area to the discharging area during CT detection. The system mainly consists of parallel conveyor belts 2, passive synchronous belt pulleys 6, tensioning mechanisms 3, conveying frames 1, active synchronous belt pulleys 7, driving mechanisms 4, and leveling mechanisms 5. When the driving mechanism 4 rotates to output torque, the active synchronous belt pulley 7 rotates accordingly. The active synchronous belt pulley 7 meshes with the inner teeth of multiple parallel conveyor belts 2, driving the multiple parallel conveyor belts 2 to rotate, realizing the synchronous driving of the multiple parallel conveyor belts 2. At the same time, to ensure uniform force, each parallel conveyor belt 2 is equipped with a set of tensioning mechanisms 3, which can independently adjust the tension force to ensure the force stability of the system. And multiple sets of leveling mechanisms 5 are installed at the bottom of the conveying frame 1 to ensure the parallelism of the transmission platform system through adjusting the leveling mechanisms 5. The whole system has a compact structure, can convey workpieces up to 5 tons at most, is suitable for the detection of large workpieces, and has strong system stability.

[0060] Embodiment 2

[0061] A specific embodiment of the present invention provides a multi-synchronous belt parallel transmission platform system for CT detection, which is improved on the basis of Embodiment 1:

[0062] In this embodiment, a chain driving mechanism with built-in nested multi-driving components for cooperative driving is provided to replace the driving mechanism 4 in Embodiment 1.

[0063] In this embodiment, as Figure 8 、 Figure 9 shown, the chain driving mechanism includes: a rotating motor, at least one set of first driving components 22, at least one set of second driving components 24, and a synchronous chain 23 sleeved outside the first driving components 22 and the second driving components 24 and capable of driving the first driving components 22 and the second driving components 24 to move synchronously.

[0064] Specifically, the first driving components 22 and the second driving components 24 have the same structural composition.

[0065] Specifically, the first driving components 22 are meshed and driven with the upper half of the parallel synchronous belt 2, and the second driving components 24 are meshed and driven with the lower half of the parallel synchronous belt 2.

[0066] In a specific implementation manner of the present invention, as Figure 10 、 Figure 11 、 Figure 12As shown, the first driving assembly 22 includes: an annular driving belt 25, a driving sprocket 27, a driving shaft 28, and a driving gear 29; the driving sprocket 27 is disposed at the end of the driving shaft 28, and a plurality of driving gears 29 are fixedly installed on the driving shaft 28 and arranged in parallel; the driving shaft 28 is rotatably installed on the conveying frame 1 through bearings.

[0067] Further, as Figure 10 shown, two sets of the driving sprocket 27, the driving shaft 28, and the driving gear 29 are arranged in parallel, and a plurality of the annular driving belts 25 are respectively sleeved outside two opposite driving gears 29; the driving sprocket 27 cooperates with the synchronous chain 23, and a plurality of driving sprockets 27 of multiple first driving assemblies 22 and second driving assemblies 24 can rotate synchronously under the drive of the synchronous chain 23. During implementation, a plurality of driving gears 29 arranged in parallel respectively drive a plurality of annular driving belts 25 arranged in parallel, and then drive a plurality of parallel conveyor belts 2 synchronously through the plurality of annular driving belts 25, realizing the synchronous drive of the plurality of parallel conveyor belts 2.

[0068] Specifically, the output shaft of the rotating motor is fixedly connected to the driving shaft 28 of the first driving assembly 22 or the second driving assembly 24, and can drive the driving shaft 28 to rotate; when the driving shaft 28 rotates, the driving sprocket 27 and the driving gear 29 rotate synchronously, and then multiple first driving assemblies 22 or second driving assemblies 24 rotate synchronously under the drive of the synchronous chain 23.

[0069] Further, as Figure 10 、 Figure 11 shown, an internal gear ring 30 capable of meshing with the driving gear 29 is provided on the inner side of the annular driving belt 25, and at the same time, an external gear ring capable of meshing with the inner teeth of the parallel conveyor belt 2 is provided on the outer side of the annular driving belt 25. During implementation, the internal gear ring 30 of the annular driving belt 25 meshes with the driving gear 29, the external gear ring meshes with the inner teeth of the parallel synchronous belt 2, and the driving chain 23 meshes and drives with a plurality of driving sprockets 27, driving the annular driving belts 25 of multiple driving assemblies to rotate synchronously to realize the power input at multiple points of the parallel conveyor belt 2, ensuring the conveying capacity of the parallel conveyor belt 2 for large-tonnage workpieces.

[0070] Further, as Figure 11 shown, an annular active driving belt 26 is connected between a plurality of annular driving belts 25; the outer surface of the active driving belt 26 protrudes from the surface of the annular driving belt 25; when the annular driving belt 25 meshes with the parallel conveyor belt 2, the active driving belt 26 is located between two adjacent parallel conveyor belts 2 and is flush with the outer surface of the parallel conveyor belt 2; when the active driving belt 26 rotates, it can directly convey the workpiece.

[0071] In a specific implementation manner of this embodiment, as Figure 8 shown, two sets of the first drive assembly 22 and two sets of the second drive assembly 24 are provided, and the first drive assembly 22 and the second drive assembly 24 are arranged in a staggered manner and form a parallelogram chain drive mechanism with the synchronous chain 23.

[0072] In a specific implementation manner of this embodiment, as Figure 9 shown, two sets of the first drive assembly 22 and one set of the second drive assembly 24 are provided, and the second drive assembly 24 is arranged in the middle of the two sets of the first drive assembly 22 and forms a trapezoidal chain drive mechanism with the synchronous chain 23.

[0073] In this embodiment, by forming a parallelogram or trapezoidal chain drive mechanism with multiple sets of drive assemblies and the synchronous chain 23, it can be ensured that the engagement wrap angle between the drive sprocket 27 of at least one set of the first drive assembly 22 / second drive assembly 24 and the synchronous chain 23 is an obtuse angle, guaranteeing the power transmission of the rotational torque of the synchronous chain 23 between multiple sets of drive assemblies.

[0074] Further, a rotary motor is fixedly connected to any one of the drive shafts 28 or drive sprockets 27 of the first drive assembly 22 or the second drive assembly 24, thereby driving the drive sprocket 27 and multiple drive gears 29 to rotate synchronously. The drive gears 29 drive multiple annular drive belts 25 to rotate, and when the annular drive belts 25 rotate, they can drive the parallel conveyor belt 2 to move, realizing the conveyance of workpieces. Specifically, the rotary motor is fixedly installed on the side of the conveyor rack 1.

[0075] In this embodiment, by arranging multiple sets of drive assemblies that are vertically staggered, the first drive assembly 22 and the second drive assembly 24 can provide tensile forces in opposite directions to the upper half and the lower half of the parallel conveyor belt 2, thereby realizing the rotary drive of the parallel conveyor belt. For the conveyance of super-large heavy workpieces (5 tons), sufficient power needs to be provided by the drive mechanism. In this embodiment, multiple rotary motors can be respectively fixedly connected to multiple drive shafts 28 of multiple sets of the first drive assembly 22 or the second drive assembly 24, and through the synchronous drive of multiple rotary motors, the synchronous operation of multiple sets of drive assemblies can be realized, thereby realizing the drive of multiple parallel synchronous belts 2.

[0076] In the drive mode of multiple-power drive driven by multiple rotary motors in this embodiment, the load capacity requirements for the rotary motors are reduced, and by arranging multiple motors to achieve a redundant drive mode of multiple-motor drive, the service life of the motors can be effectively extended. In this embodiment, the passive synchronous pulley 6 can be driven to rotate by a rotary motor, and a multi-mode cooperative drive can be realized in which multiple drive components of the chain drive mechanism and the passive synchronous pulley 6 rotate together to drive multiple parallel conveyor belts 2.

[0077] In this embodiment, the tension adjusting mechanism is a telescopic mechanism arranged at the bottom of the conveying rack 1; specifically, the conveying rack 1 is arranged as a telescopic structure, and two driven synchronous pulleys 6 are respectively rotatably installed at both ends of the conveying rack 1. The conveying rack 1 is driven by the telescopic mechanism to extend or shorten to adjust the distance between the two driven synchronous pulleys 6, so as to realize the tensioning of multiple parallel conveyor belts 2. Preferably, the telescopic mechanism is an electric push rod, a pneumatic or hydraulic driven telescopic rod.

[0078] In this embodiment, multiple groups of first driving components 22 are arranged to drive the parallel conveyor belts 2. At the same time, the driving belts 26 of multiple groups of first driving components 22 can assist in conveying the workpieces and provide a certain supporting ability, avoiding large deformations of the parallel conveyor belts 2 under the gravity of large and heavy workpieces, which is beneficial to maintaining the running stability of the conveying system and prolonging the service life of the parallel conveyor belts 2.

[0079] Embodiment 3

[0080] A specific embodiment of the present invention provides a multi-synchronous belt parallel conveying platform system for CT detection, which is improved on the basis of Embodiment 2:

[0081] In this embodiment, a replacement structure of the drive shaft assembly of the chain drive assembly in Embodiment 2 is provided.

[0082] As Figure 13 、 Figure 14 、 Figure 15 shown, compared with Embodiment 2, in this embodiment, the driving belt 26 is not provided, but a driving wheel 31 is arranged on the drive shaft 28; the driving wheel 31 is arranged in the gap between two adjacent driving gears 29, and when the driving gear 29 is in meshing with the annular driving belt 25, the driving wheel 31 can protrude from the upper surface of the annular driving belt 25.

[0083] During implementation, the workpiece moves under the drive of the parallel conveyor belt 2. When it moves to the position of the first driving component 22, it can be supported by the driving wheel 31, and the workpiece is assisted in conveying by the rotation of the driving wheel 31.

[0084] Preferably, as Figure 14 、 Figure 15 shown, the surface of the driving wheel 31 is provided with trapezoidal teeth. When a heavy object passes through the driving wheel 31, the trapezoidal teeth are elastically deformed under the action of gravity to make their height consistent with that of the parallel conveyor belt 2.

[0085] In this embodiment, the parallel conveyor belt 2 is driven by a driving component, and multiple driving wheels 31 are used for auxiliary conveying. During the rotation of the driving wheels 31, large and heavy workpieces can be driven, and the supporting effect of the driving wheels 31 on the workpieces can relieve the bearing pressure of the parallel conveyor belt 2, thereby ensuring the running stability of the parallel conveyor belt 2 and extending its service life.

[0086] As mentioned above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
