Description

Technical Field

[0001] This utility model relates to the field of red-sleeved rotor detection technology, specifically to an extendable arm for detecting red-sleeved rotor discs. Background Technology

[0002] The red-sleeved rotor disc needs to be inspected every 100,000 hours of rotor operation. Due to the special structure of the red-sleeved rotor, the inspection methods for other unit discs are not universal, and the inspection system can only be sent into the disc by a robot for inspection.

[0003] Currently, the testing of red-sleeved rotor discs can only be carried out by Siemens Energy. However, the testing costs are high and the testing time is long. In addition, the testing equipment is prone to failure, which greatly affects the testing work.

[0004] Existing extendable arm structures require multiple drive units to drive each stage of the extendable arm to extend and retract, and they are stacked layer by layer, resulting in an increase in volume as the number of stages increases. Utility Model Content

[0005] To address the aforementioned issues of numerous and bulky existing extendable arm drive units, this invention proposes an extendable arm for detecting rotor discs. This invention employs a single drive unit, with multiple telescopic structures linked by a transmission mechanism. Furthermore, a layered, nested connection ensures the overall rigidity and parallelism of the extendable arm in the horizontal direction.

[0007] Furthermore, the transmission structure includes a rack and a gear. The rack is mounted on the base, and the gear is mounted on the secondary synchronous belt module and connected to the secondary synchronous belt. The meshing of the rack and gear drives the secondary synchronous belt to rotate.

[0008] Furthermore, the primary synchronous belt module also includes two primary slide rails and a drive device; the primary synchronous belt is disposed on the primary slide rail and connected to the drive device; a slide table connecting plate is slidably disposed on the primary slide rail, and the slide table connecting plate is connected to the primary synchronous belt and the secondary synchronous belt module respectively.

[0009] Furthermore, a slide block is provided on the primary slide rail, and a slider is provided on the slide block. The slider is slidably connected to the guide rail on the secondary synchronous belt module.

[0010] Furthermore, the drive device includes a servo motor and a drive shaft, with the servo motor synchronously driving two primary synchronous belts via the drive shaft.

[0011] Furthermore, the secondary synchronous belt module also includes two secondary slide rails and a double slide connecting plate; two pulleys are provided on the secondary slide rails, the secondary synchronous belt is connected to the pulleys, and a gear drives one of the pulleys through a shaft, the end of which is connected to a double slide connecting plate; the double slide connecting plate is connected to a slide connecting plate; two slide connecting blocks are provided on the secondary slide rails, and the two slide connecting blocks are respectively connected to the secondary synchronous belt and the extension arm.

[0012] Furthermore, a section of slide block is provided on the secondary slide rail, and a slider is provided on the section of slide block. The slider and the guide rail on the extension arm are slidably connected.

It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. The described embodiments are merely some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Specific implementation method one: See Figures 1-2 This embodiment is described in detail. The extended arm for detecting a red-sleeved rotor disc described in this embodiment specifically includes a primary synchronous belt module 1, a secondary synchronous belt module 4, an extended arm 10, and a base. The primary synchronous belt module 1 is fixedly mounted on the base, and the secondary synchronous belt module 4 is slidably mounted on the primary synchronous belt module 1. The primary synchronous belt module 1 drives the secondary synchronous belt module 4 to move, and the extended arm 10 is slidably mounted on the secondary synchronous belt module 4, driving the extended arm 10 to move. A transmission structure is provided between the base and the secondary synchronous belt module 4. When relative movement occurs between the base and the secondary synchronous belt module 4, the secondary synchronous belt 16 is driven through the transmission structure.

[0020] The primary synchronous belt module 1 includes two primary slide rails 13, two primary synchronous belts 14, and a drive device. Each primary slide rail 13 has pulleys at both ends. The primary synchronous belt 14 is mounted on the primary slide rail 13 and connected to the pulleys. The drive device is located at the right end of the primary slide rail 13 and drives the pulleys to operate the primary synchronous belt 14. A sliding table connecting plate 2 is slidably mounted on the primary slide rail 13. The sliding table connecting plate 2 is connected to both the primary synchronous belt 14 and the secondary synchronous belt module 4. When the primary synchronous belt 14 operates, it drives the secondary synchronous belt module 4 through the sliding table connecting plate 2. The drive device includes a servo motor and a drive shaft. The upper end of the drive shaft is connected to a pulley on one of the primary slide rails 13 via a coupling, and the lower end of the drive shaft is connected to a pulley on the other primary slide rail 13 via a coupling. The servo motor is connected to one of the pulleys on the primary slide rail 13, thereby achieving synchronous operation of the two primary synchronous belts 14.

[0021] The left end of the primary slide rail 13 is provided with a slide block 7, and a slider 8 is provided on the slide block 7. The slider 8 is slidably connected to the guide rail 9 installed on the side of the secondary synchronous belt module 4, thereby ensuring the rigidity and parallelism between the primary synchronous belt module 1 and the secondary synchronous belt module 4, as well as the stability of the secondary synchronous belt module 4 when it extends.

[0022] The secondary synchronous belt module 4 includes two secondary slide rails 15, two secondary synchronous belts 16, and a section of double slide connecting plate 3; pulleys are provided at both ends of the secondary slide rails 15, and the secondary synchronous belts 16 are connected to the pulleys; the section of double slide connecting plate 3 is connected to the slide connecting plate 2; two sections of slide connecting blocks 5 are provided on the secondary slide rails 15, and the two sections of slide connecting blocks 5 are respectively connected to the secondary synchronous belts 16 and the extension arm 10.

[0023] A transmission structure is provided between each of the two secondary slide rails 15 and the base. The transmission structure includes a rack 11 and a gear 12. The rack 11 is fixedly mounted on the base, and the gear 12 is located at the right end of the secondary synchronous belt module 4. The gear 12 and the pulley at the right end of the secondary slide rail 15 are mounted on the same shaft, and the shaft end is connected to a double slide table connecting plate 3. The rack 11 and the gear 12 mesh. When the primary synchronous belt module 1 drives the secondary synchronous belt module 4 to move, relative movement occurs between the secondary synchronous belt module 4 and the base. The gear 12 moves along with the secondary synchronous belt module 4. The gear 12 rotates under the action of the rack 11, thereby driving the pulley on the secondary slide rail 15 to rotate, and then driving the secondary synchronous belt 16 to rotate. The secondary synchronous belt 16 drives the extension arm 10 to move and extend through the two-section slide table connecting block 5. The right end of the extension arm 10 is provided with a two-section double slide table connecting block 6, which is connected to the two-section slide table connecting block 5.

[0024] The left end of the secondary slide rail 15 is provided with a slide table fixing block 7, and a slider 8 is provided on the slide table fixing block 7. The slider 8 and the guide rail 9 installed on the side of the extension arm 10 are slidably connected, thereby ensuring the rigidity, parallelism and stability of the secondary synchronous belt module 4 and the extension arm 10 when the extension arm 10 is extended.

[0025] In summary, the extended arm for detecting a red-sleeved rotor disc described in this utility model utilizes a servo motor to drive the primary synchronous belt 14 on the primary synchronous belt module 1. The primary synchronous belt 14 drives the secondary synchronous belt module 4 to slide on the primary synchronous belt module 1. The secondary synchronous belt module 4 and the base move relative to each other. At this time, the meshing of gear 12 and rack 11 drives the secondary synchronous belt 16, which in turn drives the extended arm 10 to slide on the secondary synchronous belt module 4, achieving the effect of synchronous extension of the secondary synchronous belt module 4 and the extended arm 10. The extended arm for detecting a red-sleeved rotor disc of this utility model features a layered, nested connection between the primary synchronous belt module 1, the secondary synchronous belt module 4, and the extended arm 10 via sliders. This ensures the horizontal rigidity and parallelism of the entire extended arm 10 while reducing its overall volume, resulting in a more compact structure.
