[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] First Embodiment Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the ring-shaped RGV transport vehicle with quick track changing provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the transmission switching device. Figure 3 for Figure 2 The enlarged schematic diagram of section A is shown. The ring-shaped RGV transport vehicle with rapid track changing includes: a conveying device 1, a switching device 2, and a cleaning device 3; The switching device 2 includes a servo motor 23, a rotating frame 24, a telescopic component 25, and a lifting component 26. The lifting component 26 is fixedly installed at one end of the conveying device 1. The top of the servo motor 23 is fixedly installed at the output end of the lifting component 26. One side of the rotating frame 24 is fixedly installed at the output end of the servo motor 23. The telescopic component 25 is fixedly installed inside the rotating frame 24. The cleaning device 3 includes a movable frame 31 and a cleaning component 32. The movable frame 31 is fixedly installed at the output end of the telescopic component 25, and the cleaning component 32 is fixedly installed on the surface of the inner wall of the movable frame 31.
[0019] The conveying device 1 is an RGV trolley with a circular track in the prior art.
[0020] Two sets of switching devices 2 and cleaning devices 3 are provided at both ends of the conveying device 1. These devices are used to clean the surface of the track when the conveying device 1 is moving, so as to facilitate the cleaning of the track and prevent the accumulation of debris from affecting the use of the conveying device 1.
[0021] Both the telescopic component 25 and the lifting component 26 are hydraulic rods, electric push rods, and cylinders, used to drive the servo motor 23 and the moving frame 31 to move, respectively.
[0022] Cleaning component 32 includes cleaning cotton, rubber sheet, etc., used to clean debris accumulated on the track surface.
[0023] The switching device 2 further includes a moving groove 21 and a moving block 22. The moving groove 21 is opened inside the conveying device 1, and the moving block 22 is slidably connected to the inside of the moving groove 21.
[0024] One side of the moving block 22 is fixedly installed on one end of the servo motor 23, and is used to drive the moving block 22 to move inside the moving slot 21 when the servo motor 23 moves, thereby increasing the stability of the servo motor 23 when it moves.
[0025] The telescopic component 25 is a double-headed hydraulic rod, which is fixedly installed inside the rotating frame 24.
[0026] The movable frame 31 consists of three sections, with the middle section fixedly installed on the rotating frame 24, and the other two sections fixedly installed on one end of the movable rod fixedly installed at the output end of the double-headed hydraulic rod. This is used to push the movable frame 31 to move and separate when the double-headed hydraulic rod is activated, thereby facilitating the separation of the movable frame 31 from the track.
[0027] The cleaning component 32 is a cleaning sponge, which is fixedly installed on the inner wall surface of the movable frame 31.
[0028] Cleaning sponges are used to wipe away debris accumulated on the track surface, thereby cleaning the track.
[0029] The working principle of the quick-track changing circular RGV transport vehicle provided by this utility model is as follows: When in use, the conveyor 1 moves to one side, which drives the moving frame 31 connected to the cleaning component 32 to move and clean the track.
[0030] When the cleaning effect of the cleaning component 32 decreases, the telescopic component 25 is activated to push the moving frame 31 to move and separate. Then, the lifting component 26 is activated to retract, driving the servo motor 23 to connect the rotating frame 24 to move upward, so that the moving frame 31 is separated from the track.
[0031] After the servo motor 23 drives the rotating frame 24 to rotate 180° to clean the two moving frames 31, the servo motor 23 is reset by starting the lifting component 26. At the same time, the telescopic component 25 is retracted to merge the moving frames 31, so that the cleaning component 32 comes into contact with the surface of the track.
[0032] Compared with related technologies, the circular RGV transport vehicle with quick track changing provided by this utility model has the following advantages: This utility model provides a ring-shaped RGV transport vehicle with quick track changing. The cleaning device 3 cleans the track when the conveying device 1 moves to one side, which facilitates the cleaning of the track and prevents the accumulation of debris from affecting the use of the conveying device 1. At the same time, the switching device 2 cleans the two cleaning devices 3, which makes it easier to clean the track after cleaning the cleaning devices 3.
[0033] Second Embodiment Please refer to the following: Figure 4 , Figure 5 and Figure 6 Based on the quickly-changing ring-shaped RGV transport vehicle provided in the first embodiment of this application, the second embodiment of this application proposes another quickly-changing ring-shaped RGV transport vehicle. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0034] Specifically, the difference in the second embodiment of this application regarding the quick-change track-changing annular RGV transport vehicle is that the rotating frame 24 of the quick-change track-changing annular RGV transport vehicle is provided with a sliding device 4 inside. The sliding device 4 includes a sliding groove 41 and a sliding block 42. The sliding groove 41 is opened inside the rotating frame 24, and the sliding block 42 is slidably connected to the inside of the sliding groove 41.
[0035] The sliding groove 41 is a T-shaped groove, and the sliding block 42 is a T-shaped block that is adapted to the sliding groove 41. One end of the sliding block 42 is fixedly connected to the top of the movable frame 31 for installing or removing the movable frame 31.
[0036] The sliding block 42 is provided with a fixing member 5 inside, which is used to limit the sliding block 42.
[0037] The fastener 5 is a snap-fit, used to limit the sliding block 42.
[0038] The fixing component 5 is a bolt, and the sliding block 42 and the rotating frame 24 both have threaded holes that are compatible with the bolt.
[0039] After the bolt is installed into the threaded hole, the sliding block 42 and the rotating frame 24 are limited.
[0040] The working principle of the quick-track changing circular RGV transport vehicle provided by this utility model is as follows: In use, after removing the fixing piece 5, the moving frame 31 is moved to one side, thereby causing the sliding block 42 to move to one side inside the sliding groove 41 and separate.
[0041] When the movable frame 31 is installed, the fixing piece 5 is installed after the sliding block 42, which is fixedly connected to the top of the movable frame 31, is inserted into the sliding groove 41.
[0042] Compared with related technologies, the circular RGV transport vehicle with quick track changing provided by this utility model has the following advantages: This utility model provides a ring-shaped RGV transport vehicle with quick track changing. The sliding device 4 and the fixing part 5 are used to disassemble and install the moving frame 31, so as to facilitate the removal of the cleaning part 32 for replacement or cleaning.
