Technical Field

[0001] This utility model relates to the field of roller inspection technology, and in particular to a roller fault detection device that can be remotely monitored. Background Technology

[0002] A roller is a cylindrical, rotating component on a machine, such as a shaft or leather roller. In industrial applications, a roller refers to a cylindrical object or machine part that can roll, and it is widely used in many industries and fields for transmission, guidance, and other structures. Rollers typically need to be inspected before mechanical assembly.

[0003] The patent specification with announcement number CN201921794409.X discloses a roller detection device, which "includes an operating table, a support base, a display, a controller, and a first guide rail. The roller is supported and fixed by the support base. The clamping device is slidably connected to the first guide rail. The first guide rail is fixedly installed on the surface of the operating table. Laser runout measuring instruments are respectively provided on both sides of the roller. The laser runout measuring instruments are electrically connected to the display and the controller respectively. The controller is electrically connected to a control button for controlling the measurement of the laser runout measuring instruments. The laser runout measuring instruments are connected to the operating table through a sliding component and perform parallel displacement relative to the roller."

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned detection device: In the application of traditional roller detection devices, the inspection personnel usually conduct the inspection around the roller. This inspection method is inconvenient to observe, has low inspection efficiency, and the personnel use hand tools for inspection, which can easily lead to deviations in the accuracy of roller inspection. At the same time, the workload of the inspection personnel is too large and cannot meet the requirements of batch production inspection. In view of this, a roller fault detection device that can be remotely monitored is provided to overcome the above defects. Utility Model Content

[0024] Reference Figure 1-6 This utility model provides a remotely monitored roller fault detection device, which includes a workbench 1, movable plates 2 slidably connected to the inner walls of both sides of the top of the workbench 1, support platforms 3 fixedly provided at the top of the two movable plates 2, limit components 4 provided on the inner walls of the two support platforms 3, dust collection boxes 5 fixedly provided on both sides of the top of the workbench 1, infrared imagers 6 fixedly provided on one side of the top of the two dust collection boxes 5, dust removal components 7 provided inside the two dust collection boxes 5, and remote alarms 8 fixedly provided on one side of the top of the two dust collection boxes 5.

[0025] As a further implementation of the above technical solution: Both limiting components 4 include a first sliding groove 41, two movable seats 42, a bidirectional lead screw 43, two lead screw nuts 44, a first motor 45, a bracket 46, two rotating shafts 47, two cones 48, and a second motor 49. The two first sliding grooves 41 are respectively opened on the inner walls of the two support platforms 3. Movable seats 42 are slidably connected to both sides of the inner walls of the two first sliding grooves 41. The inside of each of the two first sliding grooves 41 is rotatably connected to the bidirectional lead screw 43 via bearings. Lead screw nuts 44 are fixedly installed on the inner walls of several movable seats 42. Each lead screw nut 44 is threadedly connected to two bidirectional lead screws 43. Two first motors 45 are fixedly mounted on one side of two support platforms 3. The drive shafts of the two first motors 45 are fixedly connected to the two bidirectional lead screws 43. Each of the tops of several movable seats 42 is fixedly equipped with a bracket 46. One side of each of the several brackets 46 is rotatably connected to a rotating shaft 47 via a bearing. One end of each of the several rotating shafts 47 is movably connected to a cone 48. A second motor 49 is fixedly mounted on one side of each of the two brackets 46. The drive shafts of the two second motors 49 are fixedly connected to two of the rotating shafts 47.

[0026] Each of several rotating shafts 47 has a connecting post 9 fixedly attached to one end. Each of the connecting posts 9 has a sliding hole 10 on its inner wall. Each of the sliding holes 10 has a sliding plate 11 slidably connected to its inner wall. Each of the sliding holes 10 has a shock absorber 12 fixedly attached to one side of its inner wall. One end of each shock absorber 12 is fixedly connected to one of the sliding plates 11. Each of the sliding plates 11 has a support rod 13 fixedly attached to one side of its side. Each support rod 13 is fixedly connected to one of the cones 48. Two first motors 45 are used to start two bidirectional lead screws 43, causing them to rotate. After the rod 43 is engaged with several lead screw nuts 44, each pair of opposing movable seats 42 slides towards each other along the inner walls of the two first sliding grooves 41, thereby allowing the two supports 46 to approach each other. After the inner walls of the two cones 48 contact the shaft end of the roller, the roller is fixed in the equipment. During the process of each pair of opposing cones 48 approaching each other to clamp the roller, several support rods 13 are affected by reverse pressure, and several sliding discs 11 slide on the inner walls of several sliding holes 10, thereby effectively protecting the clamped roller through several shock absorbers 12.

[0027] As a further implementation of the above technical solution: each of the two dust removal components 7 includes a dust collection pipe 71, an exhaust fan 72, a second slide 73, and a dust collection box 74. The two dust collection pipes 71 are respectively fixedly installed on the inner wall of the top of the two dust collection boxes 5, the two exhaust fans 72 are respectively fixedly installed on the inner wall of one side of the two dust collection boxes 5, and the two second slides 73 are respectively opened on the inner wall of the bottom of the two dust collection boxes 5. The dust collection box 74 is slidably connected to the inner wall of each of the two second slides 73.

[0028] Dust-blocking nets 19 are fixedly installed on one side of the two dust collection boxes 5. The two exhaust fans 72 create negative pressure in the two dust collection boxes 5, which can then clean the surfaces of the two rollers in the self-rotating and translating state through the two dust collection pipes 71. The cleaned dust falls into the two dust collection boxes 74 after being blocked by the two dust-blocking nets 19. The dust collected in the equipment can be processed by pulling the two dust collection boxes 74.

[0029] As a further implementation of the above technical solution: a third motor 14 is fixedly installed on the inner wall of the top center of the workbench 1. The transmission shaft of the third motor 14 is fixedly connected to a gear 15. The inner walls on both sides of the top of the workbench 1 are provided with third sliding grooves 16. The two third sliding grooves 16 are slidably connected to the two movable plates 2 respectively. The surfaces of the two support platforms 3 are fixedly provided with a number of teeth 18. The number of teeth 18 are meshed with the gear 15.

[0030] As a further implementation of the above technical solution: a remote control console 20 is fixedly installed on the surface of the workbench 1, and two infrared imagers 6, a first motor 45, two second motors 49, an exhaust fan 72 and a third motor 14 are all electrically connected to the remote control console 20.

[0031] Working principle: When using this invention, firstly, the two rollers to be tested are placed between each pair of opposing cones 48 using mechanical grippers. Then, the two first motors 45 are started via the remote control console 20. After the two first motors 45 start, the two bidirectional lead screws 43 rotate. After the two bidirectional lead screws 43 cooperate with several lead screw nuts 44, each pair of opposing moving seats 42 slides towards each other along the inner walls of the two first sliding grooves 41, thereby allowing the two supports 46 to move closer to each other and the inner walls of the two cones 48 to slide towards each other. After contacting the shaft end of the roller, the roller is fixed inside the equipment. During the process of each pair of opposing cones 48 approaching each other to clamp the roller, several support rods 13 are affected by reverse pressure, and several sliding discs 11 slide on the inner wall of several sliding holes 10 respectively. In this way, several shock absorbers 12 can effectively protect the clamped roller. Then, the exhaust fan 72, infrared imager 6 and second motor 49 start synchronously. After the two second motors 49 start, they drive the two rotating shafts 47 and the two clamped rollers to rotate respectively. At this time, the two exhaust fans 72, infrared imager 6 and second motor 49 start synchronously. The operation of the fan 72 creates negative pressure in the two dust collection boxes 5, which in turn cleans the surfaces of the two rollers in their self-rotating and translational state through the two dust collection pipes 71. The cleaned dust falls into the two dust collection boxes 74 after being blocked by the two dust baffles 19. The dust collected in the equipment can be processed by pulling the two dust collection boxes 74. At the same time, after the two infrared imagers 6 take pictures of the rollers for one revolution, the third motor 14 starts and drives the gear 15 to rotate. Through the engagement of the gear 15 with several teeth 18, the two movable plates 2 can slide along the inner walls of the two third sliding grooves 16 respectively. The rollers move horizontally a suitable distance during the self-rotation process. The above steps are repeated until the images of all roller surfaces are acquired, that is, the infrared imagers 6 acquire images from one end of the roller to the other end. The remote control system integrates the pictures transmitted by the infrared imagers 6 to form a complete 3D roller digital model. The computer then performs data comparison and analysis. If a crack is found on the roller surface, the remote alarm 8 on the same side of the roller will sound an alarm accompanied by a buzzer and stop the operation of the equipment.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
