[0030] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] Please see attached Figure 1 -Attached Figure 5The embodiment of the present invention provides a rail transit intelligent maintenance and inspection robot, including a base 1, four corners of the base 1 are fixedly connected with bidirectional motors 2, both ends of the four bidirectional motors 2 are fixedly connected with shafts 3, two shafts 3 pass through the middle of the base 1 and are rotatably connected with a movable frame 4, and the other end of each movable frame 4 is provided with a connecting arm 5, both sides of the inside of the connecting arm 5 are fixedly connected with bidirectional motors 6, both ends of the two bidirectional motors 6 are fixedly connected with shafts 7, one group of shafts 7 passes through the middle of the connecting arm 5 and is rotatably connected to the middle of the movable frame 4, and another group of shafts 7 passes through the middle of the connecting arm 5 and is rotatably connected with a walking claw 8. The other end of the walking claw 8 is rotatably connected to the adjusting seat 9, and dampers 10 are rotatably connected to both sides of the walking claw 8. The other ends of the two dampers 10 are rotatably connected to the outer wall of the adjusting seat 9, and walking wheels 11 are provided at the bottom of the adjusting seat 9. The outer wall of the adjusting seat 9 is provided with a limited position protection component, and the top of the bidirectional motor 2 is connected to a collecting box 22, and an automatic door is provided at the top of the collecting box 22. A material unloading component is provided inside the collecting box 22, and a mobile grabbing component is provided on the outer wall of the collecting box 22. Marking components are provided on both sides of the outer wall of the collecting box 22, and an angle adjustment component is provided at the bottom of the collecting box 22, and an information collection component is provided on the angle adjustment component.

[0033] Specifically, when the robot is working, it can control multiple bidirectional motors 1 2 and bidirectional motors 2 6 to flexibly mobilize and cooperate with the movable frame 4, the connecting arm 5 and the walking claw 8 to achieve walking and moving on the track. When the robot needs to perform metal flaw detection on the rail, the movable frame 4, the connecting arm 5 and the walking claw 8 can be adjusted to make the walking wheel 11 contact with the surface of the rail, and then the driving components inside the base 1 are started to make the walking wheels 11 at the four corners rotate automatically, thereby achieving the purpose of automatic movement of the robot on the rail. During the movement of the walking wheel 11, in order to prevent the walking wheel 11 from being damaged by collision when traveling on the rail, the damper 10 connected to the walking claw 8 and the adjustment seat 9 outside produces a buffering and shock-absorbing effect when the walking wheel 11 is running, thereby eliminating the impact or collision of the walking wheel 11, improving the stability of the running of the walking wheel 11 and its service life. At the same time, the adjustment seat 9 is rotatably connected to the walking claw 8, which can drive the adjustment seat 9 to move when the walking wheel 11 is hit, and has a buffering space. With the cooperation of the above components, the robot can be used in different terrains of rail transit, thus improving the maintenance efficiency of rail transit. The control parts of the robot, as well as sensors and other components are stored inside the base.

[0034] Please see attached Figure 1 The outer wall of the collecting box 22 is fixedly connected to two mounting frames 55 , and the tops of the two mounting frames 55 are fixedly connected to solar panels 56 .

[0035] Specifically, the solar panel 56 can absorb solar light and convert the solar energy into electrical energy through the equipment inside the base 1, which is then used for the operation of the robot, thereby avoiding the situation where the robot stops running due to failure to replenish electrical energy in time during work, ensuring the normal operation of the robot and further improving work efficiency.

[0036] Please see attached Figure 6 The limit protection component includes a mounting seat 12, the outer wall of the mounting seat 12 is fixedly connected to the outer wall of the adjusting seat 9, the top of the mounting seat 12 is slidably connected to two movable rods 13, the bottoms of the two movable rods 13 are rotatably connected to an obstruction shaft 15, the outer wall of the obstruction shaft 15 is fixedly connected to a roller 16, the outer sleeves of the two movable rods 13 are provided with a spring 14, the bottom of the spring 14 is arranged above the obstruction shaft 15, the middle parts of both sides of the mounting seat 12 are slidably connected to movable rods 2 18, the opposite sides of the two groups of movable rods 2 18 are rotatably connected to obstruction shafts 20, the outer wall of each obstruction shaft 20 is fixedly connected to a roller 21, the outer sleeves of the two groups of movable rods 2 18 are provided with springs 2 19, the outside of each spring 2 19 is arranged between the obstruction shaft 20 and the mounting seat 12, and the lower surface of the mounting seat 12 is connected to a metal flaw detector 17.

[0037] Specifically, when the rail is inspected for metal damage, the walking wheel 11 contacts the surface of the rail, and the mounting seat 12 wraps the outside of the rail. The two rollers 16 and the two groups of rollers 21 contact the outer wall of the rail. At the same time, affected by the width of the rail, the rollers 21 on both sides will be subject to resistance to push the blocking shaft 20 to drive the movable rod 21 to move in the opposite direction. At the same time, as the blocking shaft 20 moves, the spring 2 19 will be squeezed, so that the spring 2 19 is compressed to generate a rebound reaction force, providing thrust for the subsequent resetting of the roller 21. At the same time, affected by the contact height between the rail and the mounting seat 12, the two rollers 16 will also be subject to resistance to push the blocking shaft 15 to drive the movable rod 13 to move upward. At the same time, under the push of the blocking shaft 15, the spring 14 is compressed to generate a rebound reaction force. Under the cooperation of the above-mentioned components, the safety of the metal flaw detector 17 in contact with the outside of the rail is guaranteed, and the function can be adapted to different types of rails for use, thereby improving the scope of use of the robot.

[0038] Please see attached Figure 1 and attached Figure 7 The automatic door includes two opening and closing doors 32, and the outer walls of the two opening and closing doors 32 are rotatably connected to the two sides of the surface of the collection box 22. Both sides of the outer wall of the collection box 22 are fixedly connected with a fixed seat 2 30, and the middle parts of the two fixed seats 2 30 are rotatably connected with an electric telescopic rod 2 31, and the driving ends of the two electric telescopic rods 2 31 are fixedly connected to the surfaces of the two opening and closing doors 32.

[0039] Specifically, when the robot detects garbage, its controller will control the two electric telescopic rods 31 to start. Under the telescopic effect of the two electric telescopic rods 31, the two electric telescopic rods 31 will automatically open at the top of the collection box 22, thereby facilitating the garbage to enter the collection box 22.

[0040] Please see attached Figure 7 -Attached Figure 8 The unloading assembly includes a fixed seat 23, the bottom of which is fixedly connected to the inner bottom wall of the collecting box 22, the middle of the fixed seat 23 is rotatably connected to an electric telescopic rod 24, the outer wall of the collecting box 22 is rotatably connected to a rotating rod 25, the outer wall of the rotating rod 25 is fixedly connected to a movable plate 26, the outer wall of the rotating rod 25 is fixedly connected to a sewage discharge door 29, the sewage discharge door 29 is flush with the side of the collecting box 22, the bottom of the movable plate 26 is fixedly connected to a connecting seat 27, the driving end of the electric telescopic rod 24 is fixedly connected to a movable seat 28, and the outer wall of the movable seat 28 is rotatably connected to the middle of the connecting seat 27.

[0041] Specifically, when it is necessary to discharge the garbage inside the collection box 22, the electric telescopic rod 24 can be started. Under the telescopic action of the electric telescopic rod 24, the movable plate 26 is tilted and raised from one end inside the collection box 22. As the distance between the end of the movable plate 26 away from the rotating rod 25 and the bottom of the collection box 22 increases, the rotating rod 25 rotates synchronously. As the rotating rod 25 rotates, the sewage discharge door 29 will automatically open outside the collection box 22, and then the garbage on the upper part of the movable plate 26 will slide out from the surface of the movable plate 26, thereby achieving the purpose of automatic garbage discharge. When the electric telescopic rod 24 is extended and retracted, it will drive the movable seat 28 to rotate in the middle of the connecting seat 27, and its own bottom will rotate in the middle of the fixed seat 23, thereby ensuring that the electric telescopic rod 24 can control the tilt of the movable plate 26 through its own telescopic action.

[0042] Please see attached Figure 1 -Attached Figure 2The mobile grasping assembly includes two mounting seats 2 33, the bottoms of the two mounting seats 2 33 are respectively fixedly connected to the two sides of the outer wall of the collecting box 22, the outer walls of the two mounting seats 2 33 are fixedly connected with servo motors 1 34, the driving ends of the two servo motors 1 34 are fixedly connected with reciprocating screw rods 35, the outer walls of the collecting box 22 are fixedly connected with mounting frame 1 36, the outer walls of the two reciprocating screw rods 35 are threadedly connected with a moving frame 38, a limiting rod 37 is fixedly connected between the two groups of mounting seats 2 33 and the mounting frame 1 36, the middle parts of the two moving frames 38 are respectively slidably connected to the outer walls of the two limiting rods 37, the tops of the two moving frames 38 are provided with linear guide rails 39, the outer walls of the linear guide rails 39 are provided with moving seats 40, the outer walls of the moving seats 40 are fixedly connected with electric telescopic rods 31, the driving ends of the electric telescopic rods 31 are fixedly connected with mounting frame 2 42, and the middle part of the mounting frame 2 42 is provided with a mechanical claw 43.

[0043] Specifically, after receiving the garbage picking signal, the robot will drive the servo motor 34, the linear guide 39, the electric telescopic rod three 41 and the mechanical claw 43 to operate. Driven by the servo motor 34, the reciprocating screw rod 35 rotates, and then drives the moving frame 38 to move back and forth along the outer wall of the limit rod 37. When the mechanical claw 43 is taken away from the top of the collection box 22, the linear guide 39 drives the mechanical claw 43 to move left and right to the top of the garbage, and then the electric telescopic rod three 41 drives the mounting frame two 42 to move downward, so that the mechanical claw 43 contacts and clamps the garbage, and then reversely drives the servo motor 34, so that the mechanical claw 43 carries the garbage to the top of the collection box 22, and the mechanical claw 43 is released, and the garbage falls into the collection box 22, thereby completing the automatic garbage cleaning work and saving the cleaning work of sanitation workers in the later stage.

[0045] Specifically, when the metal flaw detector 17 detects damage on the rail, it can be transmitted to the control device through an electrical signal, so that the control device emits a start electrical signal, causing the nozzle 46 to spray the paint inside the storage box 44 toward the damaged position, thereby marking the damaged position to facilitate subsequent maintenance and replacement by the staff.

[0046] Please see attached Fig.10The angle adjustment assembly includes a limit seat 48, the top of the limit seat 48 is fixedly connected to the bottom of the collection box 22, the inside of the limit seat 48 is slidably connected to an arc-shaped tooth seat 49, the bottom of the collection box 22 is fixedly connected to a servo motor 2 50, the driving end of the servo motor 2 50 is fixedly connected to a gear 51, and the outside of the gear 51 is meshedly connected to the outside of the arc-shaped tooth seat 49.

[0047] Specifically, when collecting information, the servo motor 2 50 can be started, and the gear 51 can be rotated under the drive of the servo motor 2 50, thereby driving the arc-shaped gear seat 49 to slide inside the limit seat 48, so that the information collection component can be adjusted in angle, thereby increasing the range of information collection.
