[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0030] The utility model provides a mounted robot power supply mechanism 5, such as Figure 1-4 As shown, it includes a busbar 501, a brush 502 and a lifting device, wherein:

[0031] The busbar 501 is arranged above the track 1 of the mounted robot, and the track 1 is suspended on the top of the tunnel or factory building. The busbar 501 is wrapped with an insulating cover 503, and the insulating cover 503 is suspended and fixed on the top of the tunnel or factory building through the busbar hanger 504. A busbar groove 505 is opened at the bottom of the insulating cover 503 to expose the busbar 501, and the busbar groove 505 is arranged along the length direction of the busbar 501.

[0032] The busbars 501 are made of wear-resistant, corrosion-resistant, and highly conductive materials, such as copper alloy or silver-plated steel, to ensure stability and durability for long-term use. There can be two busbars 501, one for the positive pole and one for the negative pole, distributed on both sides of the mounted robot's track 1, preferably symmetrically.

[0033] Brush 502 is used to contact busbar 501 to draw power. It is made of a highly conductive material, such as carbon plate, to ensure good contact with the bottom of the busbar and reduce friction. Brush 502 is located below busbar 501. A vertical contact plate 506 is located on top of brush 502, extending upward from bottom to top into contact slot 505. Contact plate 506 can be in the form of a carbon strip.

[0034] The brush 502 is connected to the lifting device, which includes a pull-down mechanism 507 that pulls the brush 502 downward and a reset mechanism 508 that resets the brush 502 upward. Driven by the pull-down mechanism 507 and the reset mechanism 508, the brush 502 moves downward away from the bus bar 501 or upward into contact with the bus bar 405 to achieve power off and power supply. The brush 502 supplies power to the mounted robot through wires.

[0035] The power supply mechanism for a mounted robot provided by the present utility model is intended to solve the problem of continuous and stable power supply for a mounted robot during movement. The present utility model supplies power to the mounted robot through a busbar, and realizes automatic lifting and lowering of the brushes through a lifting device, contacting or disconnecting with the busbar, ensuring that the mounted robot obtains power supply when needed. The present utility model solves the problems of cable wear, entanglement and management difficulties in the existing cable power supply method, can provide continuous and stable power supply, and improves the reliability and efficiency of the power supply system. The power supply and power outage of the present utility model are both completed through automatic control, which reduces human intervention, improves work efficiency, and has a simple structure and is easy to maintain. The lifting mechanism of the brush ensures that the brush is in reliable contact with the busbar when needed, reducing the possibility of poor contact, and detaches when not needed, avoiding long-term contact between the brush and the busbar, thereby reducing wear and increasing service life.

[0036] As an improvement to the embodiment of the present invention, brush 502 also includes a brush holder 509. Slide plate 506 is disposed above brush holder 509. Brush holder 509 supports brush 502 and is used to connect to other components. Brush holder 509 is made of an insulating material or has an insulating layer, which insulates brush 502 from other structures.

[0037] A guide block 510 is provided below the brush bracket 509, and a vertical guide shaft 511 is connected to the bottom of the brush bracket 509. The guide shaft 511 passes through the guide block 510 and can move up and down relative to the guide block 510. A shock-absorbing spring 512 is provided on the guide shaft 511 between the guide block 510 and the brush bracket 509, which is used to provide a buffering effect when the brush 502 contacts the sliding bus bar 501.

[0038] Guide plates 513 are provided on both sides of the brush bracket 509 . The guide plates 513 extend downwards from the brush bracket 509 . The guide block 510 is located in a guide space formed by the two guide plates 513 , providing guidance for the up and down movement of the guide block 510 .

[0039] The present invention does not limit the specific structural form of the reset mechanism. As an example, the reset mechanism 508 includes a base frame 514 , a first connecting arm 515 , a second connecting arm 516 and a tension spring 517 .

[0040] The base frame 514 is used to be fixed to the mounted robot and serves as a fixed position for the overall structure of the reset mechanism 508. A first connecting rod 515 and a second connecting rod 516 are arranged in parallel. One end of the first connecting rod 515 and the second connecting rod 516 are rotatably connected (e.g., hinged) to the base frame 514, and the other end is rotatably connected to the guide block 510. The first connecting rod 515, the guide block 510, the second connecting rod 516, and the base frame 514 sequentially form a parallelogram structure. Due to the rotatable connection, the parallelogram structure can rotate and deform.

[0041] One end of the tension spring 517 is connected to the first connecting arm 515, and the other end is connected to the second connecting arm 516. The tension spring 517 is in a tensioned state, and when the guide block 510 moves downward, the tension spring 517 tends to extend.

[0042] When the pull-down mechanism 507 pulls the brush 502 and the guide block 510 downward, one end of the parallelogram-shaped guide block 510 moves downward, extending the tension spring 517. When the downward force of the pull-down mechanism 507 disappears, the tension spring 517 returns to its original position and shortens, pulling the guide block 510 upward.

[0043] As a preferred embodiment, the second connecting arm 516 is located below the first connecting arm 515, and a limit switch 518 is provided below the second connecting arm 516. When the second connecting arm 516 touches the limit switch 518 during the descent process, the winding motor is automatically controlled to stop to prevent damage caused by excessive travel.

[0044] The present invention does not limit the specific structural form of the pull-down mechanism. As an example, the pull-down mechanism 507 includes a pull wire 519 and a winding motor 520. The winding motor 520 is connected to a winding roller 522 through an output shaft 521. The upper end of the pull wire 519 is connected to the first connecting arm 515 or the second connecting arm 516, and the lower end is connected to the winding roller 522.

[0045] When it is necessary to pull down, the winding motor 520 rotates, drives the winding roller 522, and winds the pull wire 520 around the winding roller 522, thereby pulling down the guide block 510 and the brush 502. The pull wire 519 can be a rope with high strength such as a steel wire rope, polyester rope, or polyethylene rope.

[0046] A rope passing plate 523 is provided above the winding roller 522 , and a rope passing hole 524 is provided on the rope passing plate 523 , and the pull wire 519 is passed through the rope passing hole 524 .

[0047] When the winding motor 520 pulls and unwinds the pulling wire 519, the wire plate 523 straightens the pulling wire through the wire hole 524 to prevent it from being entangled or twisted.

[0048] In order to facilitate the fixing of the pulling wire 519 , a rope pressing plate 525 is provided on the winding roller 522 , and the rope pressing plate 525 squeezes the lower end of the pulling wire 519 and connects it to the winding roller 522 .

[0049] Preferably, the rope pressing plate 525 can be a part of the winding roller 522, and after the rope pressing plate 525 is connected to the winding roller 522, a complete roller is formed.

[0050] Since the busbar has two positive and negative poles, the number of brushes 502, guide blocks 510, reset mechanisms 508, and their supporting structures are two each. There is only one winding motor 520, and winding rollers 522 are symmetrically distributed on both sides of the winding motor 520, respectively cooperating with the two brushes 502.

[0051] The above is 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 principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
