Abstract
Description
Technical Field
[0001] This utility model relates to the field of omnidirectional wheel technology, specifically to an anti-entanglement structure for omnidirectional wheels on AGV chassis. Background Technology
[0002] AGV casters are a key component used in AGVs (Automated Guided Vehicles). They have omnidirectional rotation capabilities and are typically fixed under the chassis of the AGV, serving as auxiliary support. The design of the casters allows the AGV to move freely in multiple directions, adapting to complex terrain environments.
[0003] When a swivel wheel rolls, it may sometimes come into contact with linear objects on the ground. These linear objects may become entangled on the swivel wheel, affecting its rolling. Therefore, an anti-entanglement mechanism is needed to prevent linear objects from getting tangled on the swivel wheel and affecting its rolling. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an anti-entanglement structure for the AGV chassis universal wheels, thus solving the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an anti-entanglement structure for AGV chassis universal wheels, including an annular shell, a universal wheel is provided inside the annular shell, the annular shell and the universal wheel are fixedly connected, a rotating ring is rotatably connected inside the annular shell, and an air pipe is fixed at the bottom of the rotating ring;
[0006] A fixing ring is fixed to the outer wall of the trachea, and a connecting rod is integrally formed on the outer wall of the fixing ring. The connecting rod is fixedly connected to the universal wheel. A connecting pipe is fixed to the outer wall of the annular shell. A large scraper is fixed to the universal wheel, and two small scrapers are fixed inside the universal wheel.
[0007] Preferably, the caster wheel includes a mounting base, a fixed frame is rotatably connected to the bottom of the mounting base, a wheel hub is provided inside the fixed frame, and a tire is fixed to the outer side wall of the wheel hub.
[0008] Preferably, a bearing is fixed inside the hub, a fixed shaft is fixed inside the bearing, and a sealing cover is fitted on the outside of the fixed shaft.
[0009] Preferably, the front and rear surfaces of the sealing cover are provided with threaded grooves, the sealing cover and the threaded grooves are screwed together, and the fixed shaft and the fixed bracket are fixedly connected.
[0010] Preferably, a stop bar is fixed to the left side of the fixing frame, and the large scraper is located inside the stop bar.
[0011] Preferably, an air outlet is fixed at the bottom of the trachea, and the air outlet has a trumpet-shaped structure.
[0012] Beneficial effects
[0013] This utility model provides an anti-entanglement structure for the universal wheels of an AGV chassis. Compared with the prior art, it has the following advantages:
[0014] The AGV chassis's anti-entanglement structure for the casters utilizes an air pipe, an annular shell, a rotating ring, a connecting pipe, a large scraper, and a small scraper. The connecting pipe is connected to an external fan duct. When the fan is activated, air enters the annular shell, passes through the rotating ring, enters the air pipe, and finally exits from the air nozzle. The air blows away linear objects on the ground, preventing them from contacting the casters and thus avoiding entanglement. If, by chance, a linear object becomes entangled in the caster, the large and small scrapers will cut off the entangled object, further preventing entanglement. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 3This utility model provides a technical solution: an AGV chassis universal wheel anti-entanglement structure, including an annular shell 10, with universal wheels 8 inside the annular shell 10, the annular shell 10 and the universal wheels 8 being fixedly connected, a rotating ring 2 being rotatably connected inside the annular shell 10, an air pipe 4 being fixed to the bottom of the rotating ring 2, a fixing ring 3 being fixed to the outer wall of the air pipe 4, a connecting rod 1 being integrally formed on the outer wall of the fixing ring 3, the connecting rod 1 being fixedly connected to the universal wheels 8, a connecting pipe 9 being fixed to the outer wall of the annular shell 10, and the universal wheels 8 being fixed. There is a large scraper 7, and two small scrapers 11 are fixed inside the caster 8. This can prevent the caster 8 from contacting the linear object by blowing it. The large and small scrapers can also cut off the linear object that is accidentally tangled, providing double anti-tangling. A stop bar 6 is fixed on the left side of the fixing bracket 803, and the large scraper 7 is located inside the stop bar 6, which can limit the movement of the large scraper 7. An air outlet 5 is fixed at the bottom of the air pipe 4. The air outlet 5 has a trumpet-shaped structure, which can increase the area of air blowing.
[0021] Furthermore, the caster wheel 8 includes a mounting base 804, with a fixing frame 803 rotatably connected to the bottom of the mounting base 804. A hub 808 is located inside the fixing frame 803, and a tire 801 is fixed to the outer wall of the hub 808. A bearing 805 is fixed inside the hub 808, and a fixing shaft 806 is fixed inside the bearing 805. A sealing cover 807 is fitted on the outer side of the fixing shaft 806. Threaded grooves 802 are provided on both the front and rear surfaces of the sealing cover 807. The sealing cover 807 and the threaded grooves 802 are screwed together. The fixing shaft 806 and the fixing frame 803 are fixedly connected. This seals the bearing 805 and prevents linear objects from contacting and getting entangled with the bearing 805.
[0022] During operation, a blower (model CJY5015 silent centrifugal turbine micro blower) is installed on the AGV body. The blower pipe is connected to the external connecting pipe 9. When the blower is started, gas enters the interior of the annular shell 10, then passes through the rotating ring 2 and enters the air pipe 4, and finally is sprayed out from the air nozzle 5. The gas blows away linear objects on the ground to prevent them from contacting the universal wheel 8 and avoids linear objects from getting tangled in the universal wheel 8. If the universal wheel 8 accidentally gets tangled in a linear object, the tire 801 rotates with the linear object, and the large scraper 7 and small scraper 11 will scrape off the linear object tangled in the universal wheel 8. The scraped linear object will fall off the tire 801, further preventing tangling.
