Description

Technical Field

[0001] The utility model relates to the technical field of intelligent inspection robots, in particular to a telescopic mechanism used by intelligent inspection robots. Background Art

[0002] An intelligent inspection robot is a robot that integrates a variety of sensors and artificial intelligence technologies. It can perform autonomous navigation, environmental perception, data collection and other operations. The telescopic mechanism used by the intelligent inspection robot is one of the key components for the robot to achieve flexible movement and adapt to different environments. This telescopic mechanism can be extended or shortened as needed, allowing the robot to reach different locations to perform inspection tasks.

[0003] However, the traditional telescopic mechanism is not provided with an automatic retractable component for the internal cables, especially the telescopic structure used in the intelligent inspection robot. The telescopic structure needs to be frequently retracted and extended during work, which may cause the internal cables to wear or get tangled due to frequent retraction and extension, thereby accelerating the wear rate of the cables and reducing the service life of the telescopic mechanism. Furthermore, we disclose a telescopic mechanism for an intelligent inspection robot to meet the actual demand that the traditional telescopic mechanism for an intelligent inspection robot is not provided with an automatic retractable component for the cables, which may cause the internal cables to wear due to frequent retraction and extension, thereby accelerating the wear rate of the cables and reducing the service life of the telescopic mechanism. Utility Model Content

[0004] In view of this, the purpose of the utility model is to propose a telescopic mechanism for an intelligent inspection robot, so as to solve the problem that the telescopic mechanism used in a traditional intelligent inspection robot does not have an automatic cable retraction and extension component inside, which may cause the internal cables to wear due to frequent extension and retraction, thereby accelerating the wear speed of the cables and reducing the service life of the telescopic mechanism.

[0005] Based on the above-mentioned purpose, the utility model provides a telescopic mechanism for an intelligent inspection robot, including a telescopic mechanism body, an automatic cable retracting assembly is arranged at the lower end of the interior of the telescopic mechanism body, the automatic cable retracting assembly includes a retracting roller rotatably connected to the telescopic mechanism body, the outer wall of the retracting roller is provided with a spiral guide groove, and the cable (not shown in the figure) required for the telescopic mechanism body to be retracted is wound around the retracting roller through the spiral guide groove.

[0006] Preferably, one end of the retractable roller is fixedly connected to a driving gear, and the lower end of the driving gear is meshingly connected to a driven gear.

[0007] Preferably, an annular limiting plate is fixedly connected to the middle of one end surface of the driven gear, and the driven gear is rotatably connected to the lower end of the inner wall of the telescopic mechanism body through a rotating shaft on one side of the annular limiting plate.

[0008] Preferably, a first positioning column is fixedly connected to the outer side of one end surface of the driven gear, and a torsion spring is sleeved on the outer wall of the first positioning column.

[0009] Preferably, a second positioning column is sleeved on a side of the torsion spring away from the first positioning column.

[0010] Preferably, one end of the second positioning column is fixedly connected to the lower end of one side of the inner wall of the telescopic mechanism body.

[0011] Preferably, the gear ratio of the driving gear to the driven gear is 10:1.

[0012] Preferably, the lower end of the telescopic mechanism body is bolted to a base for improving the stability of the telescopic mechanism body during operation.

[0013] Preferably, a through hole is provided in the inner middle portion of the base.

[0014] Preferably, the telescopic mechanism body is a multi-stage telescopic structure.

[0015] The beneficial effects of the utility model are as follows: when the intelligent inspection robot is in use, the internal cables are spirally wound on the spiral guide groove, and when the telescopic mechanism body begins to extend and retract, the internal cables also rise accordingly, driving the retracting roller to rotate, and the active gear drives the driven gear to rotate, so that the length of the torsion spring changes, thereby increasing the tensioning force of the torsion spring; when the telescopic mechanism body is retracted, the tensioning force of the torsion spring causes the driven gear to rotate, and then the active gear drives the retracting roller to rotate, so that the cables continue to be wound on the retracting roller, thereby reducing the wear rate of the cables due to frequent extension and retraction, and increasing the service life of the telescopic mechanism.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0026] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0027] like Figures 1 to 6As shown, the telescopic mechanism used in the intelligent inspection robot includes a telescopic mechanism body 2, and an automatic cable retracting assembly 3 is arranged at the lower end of the interior of the telescopic mechanism body 2. The automatic cable retracting assembly 3 includes a retracting roller 301 rotatably connected to the telescopic mechanism body 2, and the outer wall of the retracting roller 301 is provided with a spiral guide groove 302. The cable (not shown in the figure) required for the telescopic mechanism body 2 to be retracted is wound around the retracting roller 301 through the spiral guide groove 302. When the intelligent inspection robot is in use, the internal cable is spirally wound around the spiral guide groove 302. When the telescopic mechanism body 2 starts to retract, the internal cable also rises accordingly, driving the retracting roller 301 to rotate. When the telescopic mechanism body 2 is retracted, the special component on the retracting roller 301 makes the retracting roller 301 rotate in the opposite direction compared with the cable rising, so that the cable continues to be wound around the retracting roller 301, thereby reducing the wear rate of the cable due to frequent extension and retraction, and improving the service life of the telescopic mechanism.

[0028] Further, such as Figures 2 to 6 As shown, one end of the retractable roller 301 is fixedly connected to a driving gear 308, and the lower end of the driving gear 308 is meshedly connected to a driven gear 303, and an annular limiting plate 304 is fixedly connected to the middle of one end surface of the driven gear 303, and the driven gear 303 is rotatably connected to the lower end of the inner wall of the telescopic mechanism body 2 through a rotating shaft on one side of the annular limiting plate 304, and a first positioning column 305 is fixedly connected to the outer side of one end surface of the driven gear 303, and a torsion spring 306 is sleeved on the outer wall of the first positioning column 305, and a second positioning column 307 is sleeved on the side of the torsion spring 306 away from the first positioning column 305, and one end of the second positioning column 307 is fixedly connected to the lower end of one side of the inner wall of the telescopic mechanism body 2, and the driving gear 308 is meshed with the driven gear 303. The gear ratio of the wheel 303 is 10:1. When the intelligent inspection robot is in use, the internal cable is spirally wound on the spiral guide groove 302. When the telescopic mechanism body 2 begins to extend and retract, the internal cable also rises, driving the retracting roller 301 to rotate, and the driving gear 308 drives the driven gear 303 to rotate, so that the length of the torsion spring 306 changes, thereby increasing the tensioning force of the torsion spring 306. When the telescopic mechanism body 2 is retracted, the tensioning force of the torsion spring 306 causes the driven gear 303 to rotate, and then the driving gear 308 drives the retracting roller 301 to rotate, so that the cable continues to be wound on the retracting roller 301, thereby reducing the wear rate of the cable due to frequent extension and retraction, and increasing the service life of the telescopic mechanism.

[0029] Further, such as Figure 1 to Figure 2As shown, the lower end of the telescopic mechanism body 2 is bolted to a base 1 for improving the stability of the telescopic mechanism body 2 during operation. A through hole 4 is provided in the inner middle portion of the base 1. The telescopic mechanism body 2 is a multi-stage telescopic structure. The stability of the telescopic mechanism body 2 during telescopic operation is increased by providing the base 1. The cable passes through the base 1 through the through hole 4 to be connected to the outside.
