[0002] Trams are light urban rail transit that are powered by electricity and run on rails. Since they are powered by electricity, the vehicles do not emit exhaust gas, making them a pollution-free and environmentally friendly means of transportation. Tram tracks are usually small and embedded in a concave shape on the municipal road surface. After a certain number of years of operation, the concave sides of the tracks will basically be rusted, scratched, and bruised, which will reduce the comfort of the tram during operation and also cause noise during operation. However, since the tracks are embedded in the ground, it is difficult to perform local inspection and maintenance. The current practice usually requires the entire section of track to be replaced, which has a very high maintenance cost. In addition, the replacement will cause the temporary closure of the traffic section, which brings inconvenience to people's travel. Summary of the invention

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following Figure 1-Figure 4 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention discloses a tram track inspection and maintenance device, which is specially used for the inspection and maintenance of tram tracks. The device includes a frame 2, and an upper shell cover 1 is detachably provided on the frame 2. A wheel assembly placed in the track and moving is provided at the bottom of the frame 2, and the wheel assembly includes a wheel group 22 and a motor 21 driving the wheel group 22 to rotate. Track cleaning components are provided on both sides of the frame 2, and the track cleaning components include a cleaning brush 82. A moving component 81 is provided on the upper end of the cleaning brush 82 to drive it to reciprocate horizontally, and the moving component drives the cleaning brush to move in a direction perpendicular to the forward direction of the device. The cleaning brush 82 is driven by the motor to rotate, and the debris in the track can be cleaned by the moving component 81.

[0021] A lifting mechanism 3 is arranged above the frame 2, and a detection mechanism and a maintenance mechanism are connected to the lower part of the lifting mechanism 3 through a connecting plate 4. The lifting mechanism 3 is a lifting cylinder. The lifting mechanism 3 drives the detection mechanism 7 and the maintenance mechanism 6 to reciprocate up and down along the vertical direction of the frame 2.

[0022] In the figure of this embodiment, the detection mechanism and the maintenance mechanism are under the same lifting cylinder. Of course, different lifting cylinders can also be used to be set at both ends of the device for separate control. There is no specific restriction on the number of detection mechanisms and maintenance mechanisms.

[0023] The detection mechanism 7 and the maintenance mechanism 6 are placed on the connecting plate 4 through a rotating assembly. The rotating assembly can drive the detection mechanism 7 and the maintenance mechanism 6 to rotate on the connecting plate 4.

[0024] The rotating assembly includes a first gear 72 disposed on the connecting plate 4 . The first gear 72 is meshed with a driving gear 741 disposed on one side of the first gear 72 . The driving gear 741 is connected to a driving motor 74 .

[0025] The detection mechanism 7 includes a first base 73 and a detection connecting rod placed in the first base 73. The first base 73 is connected to the first gear 72 in a concave opening shape, and a group of transversely arranged moving grooves 731 are symmetrically opened on the side wall of the first base 73. The detection connecting rod includes a main rod 75 and a secondary rod arranged at the far end of the main rod. The angle between the main rod and the secondary rod is set, and the far end of the secondary rod is provided with a detection unit 76 and a marking unit. The detection unit 76 includes an image acquisition lens, and the marking unit includes a marker pen 77 and an angle rotation component 78 connected to the rear end of the marker pen 77. The angle rotation component 78 drives the marker pen 77 to rotate at an angle to better mark the required maintenance part.

[0026] The detection link is mounted in the moving groove 731 through the moving rods 752 connected to the two sides of the main rod 75. The moving rod 752 passes through the moving groove 731 from the inner side of the first base and is connected to the moving cylinder 79 outside the first base 73. When the moving cylinder 79 works, it drives the moving rod 752 to move in the moving groove, and drives the detection link to achieve horizontal movement, which can further achieve the focus of the image acquisition lens when shooting images.

[0027] A second movable cylinder 751 is provided at the bottom of the main rod 75, and a connecting shaft is passed through the bottom pivot of the second movable cylinder 751, and the connecting shaft is mounted on the bottom of the main rod. The cylinder shaft of the second movable cylinder 751 is connected to a driving rod 753 arranged on one side of the main rod, and the driving rod 753 and the auxiliary rod are arranged on the same side of the main rod 75. The second movable cylinder 751 is lifted. Since the bottom of the second movable cylinder 751 is in the form of a pivot, the second movable cylinder 751 is a swinging cylinder. When it is working, it will drive the main rod to rotate along the extension direction of the auxiliary rod (that is, toward the direction close to the track) to drive the marker pen 77 to move toward the track to achieve marking.

[0028] The maintenance mechanism includes a second base 61 vertically arranged on the rotating assembly, a counterweight assembly 62 is arranged on one side of the second base 61, the counterweight assembly is connected to the telescopic rod assembly arranged on the other side of the second base 61, and a grinding assembly is arranged at one end of the telescopic rod assembly. In this embodiment, the counterweight assembly is embodied in the form of a counterweight block. The arrangement of the counterweight block can make the entire mechanism more stable when the grinding assembly is grinding, and will not be excessively shaken by the grinding action.

[0029] The telescopic rod assembly includes a group of telescopic rods 63 arranged in an arc shape, and the grinding assembly includes an oil injection port 65 arranged at the far end of the telescopic rod 63 and a grinding head 64 placed above the oil injection port 65. The arc angle of the telescopic rod is equivalent to the curvature of the inner surface of the track.

[0030] Specifically, an electric push rod 66 is provided between the telescopic rods 63, one end of the electric push rod 66 is connected to the telescopic rods 63 on both sides through a first connecting rod 68, and the other end of the electric push rod 66 is connected to the counterweight assembly on the other side of the second base through a second connecting rod 67. When the electric push rod 66 works, it drives the telescopic rod to extend and retract to realize the displacement action of the grinding assembly. An ink box 51 and a lubricating oil port 52 can be selectively provided above the frame 2, and the lubricating oil port 52 is connected to the oil injection port through a connecting pipe to provide lubricating oil. The ink box 51 can be connected to a marker pen through a connecting pipe to provide ink for the marker pen.

[0031] Usually, during inspection and maintenance, one side of the track surface is inspected first and then the other side. Considering the curvature of the track surface, the device needs to convert the angle as a whole when inspecting the other side. The conversion can be done manually, or the angle can be rotated by installing an automatic rotating component in the center of the device. The automatic rotating component can be combined with the corresponding rotating shaft through a rotating motor. This rotation belongs to the commonly used conversion in mechanical structures, and it is not the focus of the present invention, so it will not be repeated here.

[0032] In order to better understand the present invention, the following describes the use of the device to perform one side track surface inspection and maintenance actions:

[0033] In the initial stage, the lifting cylinder will lift the maintenance mechanism and the detection mechanism to the raised state. When it is needed, the device is placed in the track. During the movement, the track cleaning component will clean the stones and the like in the track. The lifting cylinder will drive the detection mechanism and the maintenance mechanism to move downward to the waiting position.

[0034] The motor of the rotating component works to drive the detection mechanism to rotate, and the moving cylinder 79 works to drive the main rod to move to adjust the focal length by the distance from the guide surface. The image acquisition mechanism will be connected to the processing and analysis system of the device. After the image is collected, it will be analyzed and identified. If it is a defective part, the second moving cylinder 751 will work, and at the same time, combined with the angle rotation component 78 at the rear end of the marker pen, the defective position will be marked with the marker pen.

[0035] The maintenance mechanism also realizes the angular rotation through the rotating assembly at the bottom. The electric push rod 66 drives the telescopic rod to extend and retract. When it reaches the processing position, the grinding head of the grinding assembly will start grinding. During grinding, the system will control the wheel assembly to reciprocate back and forth to assist the grinding assembly in the horizontal reciprocating grinding. After the grinding is completed, the oil injection port sprays oil at the grinding position for protective treatment.

[0036] The specific control of the system in the present invention belongs to the software part and is not the focus of protection of the present invention, so it will not be described here.

[0037] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0038] There are many specific application examples of the present invention. 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 can be made without departing from the principle of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
