AI Technical Summary

Technical Problem

Existing rail-mounted robots are prone to derailment when power is interrupted, and the long-term concentrated use of the electric braking structure will lead to wear and slipping, affecting the braking effect.

Method used

A rail-mounted robot braking structure is designed including a walking assembly that can walk along a track, a U-shaped bracket, a slider, a fixed magnetic ring, a moving magnetic ring and a brake assembly. When the power supply is normal, the fixed magnetic ring absorbs the moving magnetic ring, causing the slide plate and the brake assembly to stay away from the track; when the power is interrupted, the magnetism disappears, and the first spring releases potential energy, bringing the slide plate close to the track, and the brake assembly contacts the track to provide braking friction.

Benefits of technology

When power is interrupted, the contact friction of the brake assembly can offset the inertial sliding, ensuring that the robot stops in time and avoids derailment; at the same time, multiple brake components are distributed in multiple positions to increase the braking position and effect, avoid wear caused by concentrated braking, and improve the overall braking effect.

[0001] The utility model relates to the technical field of robot braking, in particular to a rail-hanging robot braking structure. Background Art

[0002] A rail-mounted robot refers to a robot that can be suspended on a track and move along the track. A rail-mounted robot can be used to perform various inspection tasks. It usually carries various working units such as explosion-proof cameras, smoke sensors, and harmful gas sensors for inspection work. In terms of track structure, I-beam tracks are mostly used. According to the track layout type, it can be roughly divided into two types: ground rails and overhead rails (hanging rails).

[0003] However, existing rail-mounted robots are often only equipped with electric braking structures when walking along the track. When the power is suddenly interrupted and the electric braking structure fails, the rail-mounted robot will continue to walk a distance along the track due to inertia, which can easily lead to derailment. In the process of braking only by the electric braking structure, the rail-mounted robot will also wear out due to the long-term concentration of the braking position, and then slipping will occur, affecting the braking effect of the rail-mounted robot.

[0004] Therefore, it is necessary to invent a rail-hanging robot braking structure to solve the above problems. Utility Model Content

In the process of braking only by the electric braking structure, the rail-mounted robot will also suffer from wear due to the long-term concentration of the braking position, and then the phenomenon of slipping will occur, which affects the braking effect of the rail-mounted robot.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] When the slide plate gradually approaches the side wall of the track, the angle between the rotating rod and the slide plate gradually decreases and the second spring is continuously compressed.

[0010] As a preferred solution of the utility model, the brake assembly includes a swivel seat rotatably connected to the swivel rod, a connecting plate installed on the non-rotating side of the swivel seat, and a brake friction plate installed on the other end of the connecting plate.

[0023] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0024] The utility model provides Figure 1-4 The brake structure of a rail-mounted robot shown in the figure comprises a plurality of walking components 2 that can walk along a track 1 and a U-shaped bracket 3 arranged between the bottom ends of the plurality of walking components 2. The robot body is detachably arranged below the U-shaped bracket 3. The top ends of the U-shaped bracket 3 are located at positions on both sides of the track 1. Vertical plates 7 that can be slidably installed in a lockable installation position in a direction close to or away from the track 1 are provided. A pull rod 8 is slidably passed through the center of the vertical plate 7. A slide plate 10 is connected to the other end of the pull rod 8. A first spring is sleeved on the portion of the pull rod 8 located between the vertical plate 7 and the slide plate 10. 9. Both side walls of the vertical plate 7 are provided with fixed magnetic rings 13 that can be energized to manage magnetism. Both side walls of the slide plate 10 can be detachably installed with moving magnetic rings 14 that can be in magnetic contact with the fixed magnetic rings 13. Rotating rods 16 are rotatably provided at the four corners of the two side walls of the slide plate 10. The other end of the rotating rod 16 is rotatably connected to a brake assembly that can abut and rub against the side wall of the track 1. When the power supply is normal, the fixed magnetic ring 13 is energized and has magnetism, so that the moving magnetic ring 14 is magnetically attracted, so that the brake assembly is separated from the track 1, thereby avoiding affecting the normal movement of the walking assembly 2 along the track 1.

[0025] Side plates 15 are installed at the four corners of the two side walls of the slide plate 10, one end of the rotating rod 16 is connected to an arc rod 17 that can slide in an arc shape and penetrate the side plate 15, and the part of the arc rod 17 between the side plate 15 and the rotating rod 16 is sleeved with a second spring 18;

[0026] When the skateboard 10 gradually approaches the side wall of the track 1, the angle between the rotating rod 16 and the skateboard 10 gradually decreases and continuously compresses the second spring 18. When the skateboard 10 approaches the track 1, the second spring 18 is compressed so that the brake friction plate 21 is fully in contact with the side wall of the track 1, thereby maximizing the braking friction effect of the brake friction plate 21.

[0027] The brake assembly includes a swivel seat 19 rotatably connected to the swivel rod 16, a connecting plate 20 installed on the non-rotating side of the swivel seat 19, and a brake friction plate 21 installed on the other end of the connecting plate 20. The brake friction plate 21 can contact the side wall of the track 1 and provide braking friction. The swivel seat 19 is rotatably connected to the swivel rod 16, so that when the angular position of the swivel rod 16 is not determined, the brake friction plate 21 can be fully contacted with the side wall of the track 1 through the rotation of the swivel seat 19.

[0028] Fixed sockets 11 are installed on both side walls of the vertical plate 7, and dynamic connecting seats 12 are installed at the matching positions on both sides of the skateboard 10. The fixed magnetic ring 13 is installed on the side of the fixed socket 11 close to the skateboard 10. One end of the dynamic connecting seat 12 is connected to a plug rod 23 that can slidably penetrate the fixed magnetic ring 13 and the fixed socket 11. The dynamic magnetic ring 14 is fixedly sleeved in the middle of the plug rod 23. The plug rod 23 can limit the sliding direction of the dynamic magnetic ring 14 and exists synchronously with the pull rod 8, thereby limiting the sliding direction of the skateboard 10 and multiple brake friction plates 21.

[0029] A manually pull-out bracket 22 is installed at one end of the pull-out rod 8 away from the slide plate 10 . After power is turned on again, manually applying force to the pull-out bracket 22 can shift the moving magnetic ring 14 to a contact position with the fixed magnetic ring 13 again.

[0030] A plurality of transverse grooves 4 are provided in the U-shaped bracket 3, and a positioning stud 5 which can slide along the transverse groove 4 is connected to the position where the bottom end of the vertical plate 7 fits into the transverse groove 4. The threaded sleeve of the positioning stud 5 located below the U-shaped bracket 3 is provided with a rotating bracket 6 which can lock the position of the positioning stud 5. The position of the positioning stud 5 in the transverse groove 4 is determined according to the size of the walking component 2 and the transverse thickness of the track 1. By adjusting the position of the vertical plate 7, it is ensured that the brake component can contact the side wall of the track 1 during the process of releasing the elastic potential energy of the first spring 9.

[0031] In the utility model, under the condition of normal power supply, the fixed magnetic ring 13 is energized and has magnetism, so that the moving magnetic ring 14 is magnetically attracted, and then the first spring 9 is compressed and the slide plate 10 slides in the direction away from the track 1, so that the multiple rotating rods 16 and the multiple brake components slide in the direction away from the track 1, that is, the brake component is separated from the track 1, so as to avoid affecting the normal walking of the walking component 2 along the track 1; when the power is suddenly interrupted, the fixed magnetic ring 13 is powered off and the magnetism disappears, thereby losing the magnetism of the moving magnetic ring 14. At this time, the compressed first spring 9 releases the compressed elastic potential energy under the limit of the pull rod 8 and drives the slide plate 10 to slide in the direction close to the track 1, until the multiple brake components are respectively in contact with multiple positions of the track 1 and provide braking friction, so that the rail-hanging robot can offset the inertial sliding and stop in time in the power-off state under the contact friction braking of the multiple brake components, avoiding derailment and other problems. In addition, the brake components are provided in multiple positions and are respectively located in multiple positions. On the one hand, the braking position and braking effect can be increased when they are in common contact, and on the other hand, the wear of the brake components caused by concentrated braking can be avoided, thereby further improving the braking effect.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
