Description

Technical Field

[0001] The present invention relates to the technical field of mobile charging, and particularly to a track for a rail-mounted mobile charging robot and a safe power supply device composed thereof. Background Art

[0002] In recent years, with the rapid development of the new energy vehicle industry, the number of electric vehicles in use has been increasing year by year, and the development prospect of mobile charging robots for power supply is also becoming broader and broader. There are various mobile charging robots on the market now. Among them, the rail-mounted mobile charging robot stands out due to its low cost and non-occupation of the limited ground space. The track necessary for its installation and supporting is an important part of such a robot system. However, there are many problems with the common tracks and their systems on the market at present: for example, some rail-mounted mobile charging robots adopt a drag chain power supply system. The installation of the drag chain is complex. It not only requires separate hoisting, but also needs to be parallel to the track. It is huge in volume, occupies a large space, and has extremely high costs; or a single-pole multi-group sliding contact wire power supply system is adopted. The sliding contact wire is exposed, with low protection performance, short service life, easy aging, and easy accidental contact with the sliding contact wire electrode during manual installation and maintenance, with low safety factor; some tracks adopt simple installation methods such as welding and self-tapping screws. The hoisting space in many underground parking lots is narrow, and the top pipeline layout is complex. General simple tracks cannot be constructed and installed, and there are easy installation defects in the butt joint of multiple sections of tracks, and the system stability is extremely poor; at the same time, a robot positioning module needs to be additionally installed on some tracks. If the robot deviates or shakes slightly, it cannot trigger identification and positioning, and the reliability of the whole system is poor. The separately installed positioning module lacks effective protection and is also extremely easy to be damaged and invalidated.

[0003] Therefore, there is an urgent need for a charging robot track that is safer, more stable, more reliable, and has a smaller space occupation ratio, and a safe power supply system composed thereof. Summary of the Invention

[0004] Object of the Invention: The object of the present invention is to provide a track for a rail-mounted mobile charging robot and a safe power supply device composed thereof, aiming at the deficiencies of the prior art, without using a drag chain power supply system and a sliding contact wire power supply system, ensuring the safety of power taking and using, convenient hoisting, and having less requirements for the hoisting space.

[0005] Technical Solution: A track for a rail-mounted mobile charging robot according to the present invention has an embedded cable integrally formed above the interior of the track. Two symmetrical inclined planes are provided on the upper part of the track. A folded edge notch is provided on one outer side edge of the track. Both ends of the track are sealed by track end caps.

[0006] Further, the embedded cable is a 3-pole seamless sliding contact wire.

[0007] Further, every two tracks are connected by a straight connector.

[0008] Furthermore, a waist groove is provided at the top of the track to adjust the hoisting height.

[0009] The present invention also provides a safety power supply device for a rail-mounted mobile charging robot, including a track, a robot hanging wheel slidably connected to the track, and a robot fixedly connected to the bottom of the robot hanging wheel. The robot can move for charging and can move on the rail-mounted track; the driving wheel of the robot is in close contact with the lower part of the track to provide power for the robot to move on the track.

[0010] Furthermore, a positioning module is slidably arranged in the hemmed notch. The positioning module does not move with the robot and can move arbitrarily in the hemmed notch through a T-bolt.

[0011] Furthermore, a robot current collector is arranged inside the track head. There are 3 robot power supply pieces arranged inside the robot current collector; the embedded cable includes three groups of conductive wires, namely a live wire, a neutral wire, and a ground wire; the 3 robot power supply pieces are respectively in contact with one end of the live wire, the neutral wire, and the ground wire.

[0012] Furthermore, three copper pieces are arranged inside the track head, and the three copper pieces are respectively in contact with the other ends of the live wire, the neutral wire, and the ground wire.

[0013] Furthermore, the three copper pieces lead out the live wire, the neutral wire, and the ground wire to the wiring terminals of the track head. The wiring terminals are connected to the live, neutral, and ground wires of the external distribution box. The distribution box supplies power to the embedded cable on the track, and the embedded cable supplies power to the robot. At the same time, a wire is branched out from the ground wire and connected to the hemmed notch on the track through a screw.

[0014] Advantageous effects: Compared with the prior art, the advantages of the present invention are as follows:

[0015] (1) In the present invention, through the embedded cable, that is, a 3-pole seamless sliding contact wire is used to replace the drag chain power supply system, the power taking device of the robot can be in sliding contact with the embedded cable for power supply, and it is stationary during charging, avoiding the problem of complex installation of the drag chain; at the same time, it has high protection performance, high safety performance, and reduced space;

[0016] (2) The present invention adopts a 3-pole seamless sliding contact wire, and the whole sliding contact wire is surrounded with the opening facing downwards, so it has high protection performance and water cannot seep in from above;

[0017] (3) In the present invention, the tracks are connected with a straight connector to ensure the horizontality of the tracks. The hemmed notch above the tracks is used to install track hanging brackets, and the position can be adjusted. The waist groove structure of the track hanging brackets can adjust the hoisting height, ensuring the horizontality of the tracks after hoisting in multiple aspects and adapting to the complex pipelines above the tracks;

[0018] (4) The positioning module in the present invention is embedded in the flanging notch on the side of the track, and its position can be adjusted to anywhere; moreover, since it is embedded, it is not easily collided and damaged. BRIEF DESCRIPTION OF THE DRAWINGS
