[0022] As shown in Figures 1-3 A kind of anti-derailing structure for intelligent car, including a group of channel rail 1 and intelligent car 2, the bottom of intelligent car 2 can be installed multiple anti-derailing structures, and anti-derailing structure includes the side plate support 4 that rotationally connects with walking wheel 3, two support wheel seats 5 are slidably connected on side plate support 4 along vertical direction and the driving mechanism that can drive two support wheel seats 5 synchronous and move towards or away from each other;Walking wheel 3 can roll along the rail surface on channel rail 1, a plurality of limiting wheels 6 that can be attached to the rail head bottom side or rail bottom upper side of channel rail 1 are rotationally connected on support wheel seat 5, and the rotating shaft of limiting wheel 6 and the direction of intelligent car 2 walking on channel rail 1 are perpendicular to each other.

[0023] When working, the position of two support wheel seats 5 can be adjusted by driving mechanism first, so that the limiting wheel 6 on two support wheel seats 5 can be attached to the rail head bottom side or rail bottom upper side of channel rail 1. At the same time, since the rotating shaft of limiting wheel 6 and the direction of intelligent car 2 walking on channel rail 1 are perpendicular to each other, this makes the limiting wheel 6 can accurately limit the car laterally. When intelligent car 2 has the tendency of derailing and overturning due to high-speed driving or turning, i.e. intelligent car 2 has the trend of deviating to both sides of channel rail 1, limiting wheel 6 can prevent intelligent car 2 from leaving through the force between the rail head bottom side or rail bottom upper side of channel rail 1.

[0024] Further, as shown in Figure 1As shown, in order to further improve the stability of the intelligent car 2 when walking, a limiting rail 101 is arranged on the I-shaped track 1, the limiting rail 101 is located in the middle of the track surface of the I-shaped track 1, and the walking wheel 3 can be clamped on both sides of the limiting rail 101, that is, the middle of the walking wheel 3 is provided with an annular groove, the bottom of the annular groove can roll on the surface of the limiting rail 101, and the outer surface on both sides of the annular groove on the walking wheel 3 can roll on the track surface of the I-shaped track 1, thereby preventing the walking wheel 3 from being separated from the I-shaped track 1. At the same time, in the technical solution, in order to ensure the bearing capacity of the I-shaped track 1, the I-shaped track 1 and the limiting rail 101 are integrally formed.

[0025] As shown above, Figure 2 、 Figure 3 As shown, the two support wheel seats 5 can move synchronously towards or away from each other under the driving of the driving mechanism. Specifically, the driving mechanism includes a rack 7 connected to the two support wheel seats 5 respectively, the rack 7 is arranged along the moving direction of the support wheel seat 5, the two racks 7 are parallel to each other and meshed with a large gear groove group 801 on a double gear 8, and a worm 9 meshed with a small gear groove group 802 on the double gear 8 is rotatably connected to the side plate support 4, one end of the worm 9 extends to the outside of the side plate support 4, and a multi-edge groove is formed at the end of the worm 9. The multi-edge groove at the end of the worm 9 can be matched with a hexagonal wrench and other tools, and by rotating the worm 9, the double gear 8 meshed with it can be rotated. The rotation of the double gear 8 can drive the two racks 7 meshed with it to move synchronously, thereby realizing the synchronous movement of the two support wheel seats 5 towards or away from each other. At the same time, in the technical solution, the small gear groove group on the double gear 8 is a turbine gear groove, which has self-locking property when meshing with the worm 9, so that the positions of the two support wheel seats 5 on the side plate can remain unchanged without external force.

[0026] Further, in the technical solution, in order to ensure the linear operation of the two support wheel seats 5, the support wheel seat 5 can be slidably connected to the side plate support 4 through a linear guide rail. Specifically, the linear guide rail is composed of a guide rail and a sliding block, the guide rail can be embedded in the side plate support 4, and the two ends of the guide rail are respectively provided with stoppers to prevent the sliding block from being separated from the guide rail. At the same time, the support wheel seat 5 is installed on the sliding block, and when the sliding block abuts against the stoppers at the ends of the guide rail, the rack 7 connected to the support wheel seat 5 is still meshed with the double gear 8.

[0027] In the embodiment, the bottom of the intelligent car 2 is provided with four anti-derailing structures, and the four anti-derailing structures are symmetrically distributed on a group of I-shaped tracks 1. The four anti-derailing structures are symmetrically distributed, which can provide all-round support and limiting for the intelligent car 2, ensure that the intelligent car 2 can run smoothly along the I-shaped track 1, effectively resist the deviation tendency caused by uneven track, slight vibration or external interference force, and ensure the stability of the intelligent car 2 when moving.

[0028] Further, in the technical solution, the limiting wheel 6 is a rubber roller, the force receiving surface of the rubber roller has a certain deformation capacity, and the force acting on the limiting wheel 6 when the intelligent car 2 slightly shakes can be effectively offset.

[0029] Working principle: the positions of the two support wheel seats 5 can be adjusted by rotating the worm 9 first, so that the limiting wheels 6 on the two support wheel seats 5 can abut against the rail head bottom side or the rail bottom upper side of the work-type track 1. At the same time, since the rotation axis of the limiting wheel 6 is perpendicular to the direction in which the intelligent car 2 walks on the work-type track 1, the limiting wheel 6 can accurately limit the car laterally. When the intelligent car 2 has a tendency to derail and overturn due to high-speed driving or turning, that is, when the intelligent car 2 has a tendency to deviate to the two sides of the work-type track 1, the limiting wheel 6 can prevent the intelligent car 2 from deviating through the force between the limiting wheel 6 and the rail head bottom side or the rail bottom upper side of the work-type track 1.
