Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, specifically to a self-lubricating ground rail robot. Background Technology

[0002] When using a ground-rail robot, staff need to regularly lubricate and maintain the ground rails. However, lubrication and maintenance require the equipment to be shut down. Frequent shutdowns reduce the utilization rate of the equipment, which in turn affects the overall production efficiency.

[0003] According to a self-lubricating ground rail robot (publication number: CN222755445U), the above application includes a ground rail and a drive mechanism. Track grooves are opened on both sides of the inner wall of the ground rail, and multiple automatic lubrication mechanisms are equally spaced on both sides of the top of the ground rail. The automatic lubrication mechanism includes a socket opened on the top of the ground rail, and the bottom of the socket is connected to the track groove. A graphite column is inserted into the socket.

[0004] However, in actual use, replacing or replenishing graphite columns of the above-mentioned ground rail robot usually requires disassembling the sockets one by one, removing the worn graphite columns, and then installing new columns. The longer the ground rail, the more graphite columns there are, and the longer the maintenance is required. Maintenance personnel need to move along the long ground rail, bend over or reach out to operate, and each column needs to be handled, which is labor-intensive. In view of this, we propose a self-lubricating ground rail robot. Utility Model Content

[0017] Compared with the prior art, this utility model provides a self-lubricating ground track robot, which has the following beneficial effects:

[0018] 1. This self-lubricating ground rail robot, through its set cleaning and lubrication components, has graphite pillars installed on the robot that automatically release lubrication through rolling friction, eliminating the need for frequent refueling or shutdowns. Simultaneously, multiple graphite pillars are installed in the loading rack, which can automatically replenish lubrication under gravity, ensuring continuous lubrication without manual intervention, extending maintenance cycles. An arc-shaped brush cleans the contact surface between the ground rail body and the drive wheel, removing dust, iron filings, graphite powder, and other impurities, ensuring clean contact surfaces between the drive wheel, graphite pillars, and ground rail body, achieving effective lubrication, reducing frictional resistance and wear rate, and extending the lifespan of the drive wheel and ground rail body.

[0019] 2. This self-lubricating ground rail robot uses springs to keep the friction wheel pressed tightly against the ground rail body. The springs continuously apply force, ensuring that the friction wheel always maintains close contact with the ground rail surface. No matter how uneven or vibrating the ground rail body is, the friction wheel will not loosen, ensuring the normal operation of the drive or cleaning device. Attached Figure Description

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a self-lubricating ground rail robot, including a robotic arm 1, a drive box 2 fixedly connected to the bottom of the robotic arm 1, a drive motor fixedly connected to the inner wall of the drive box 2, a drive wheel 3 fixedly connected to the output end of the drive motor, and a cleaning and lubrication assembly 5 provided on the outer wall of the drive box 2. The cleaning and lubrication assembly 5 includes a loading rack 501, a baffle 502, a graphite column 503, a fixing frame 504, a connecting rod 505, a mounting frame 506, a friction wheel 507, a rotating shaft 508, an arc-shaped brush 509, a collection box 510, and a belt 511.

[0026] In one embodiment of this utility model, the loading rack 501 is fixedly connected to the outer wall of the drive box 2, and the inner wall of the loading rack 501 is fixedly connected to the baffle 502. The loading rack 501 is provided with a graphite column 503 inside, and the graphite column 503 is movably connected to the drive wheel 3. The two ends of the graphite column 503 are hemispherical, and the hemispherical shape makes it easy for the graphite column 503 to rotate.

[0027] The fixed frame 504 is fixedly connected to the top end face of the drive box 2. The side wall of the fixed frame 504 is provided with a connecting rod 505. The end face of the connecting rod 505 is fixedly connected to the mounting frame 506. The bottom of the mounting frame 506 is rotatably connected to a friction wheel 507. The friction wheel 507 is movably connected to the inner wall of the ground rail body 4. The top of the friction wheel 507 is fixedly connected to a pulley, which is connected to the belt 511 for transmission.

[0028] The rotating shaft 508 is rotatably connected to the mounting bracket 506. An arc-shaped brush 509 is fixedly connected to the side wall of the rotating shaft 508. A pulley 2 is fixedly connected to the top of the rotating shaft 508. The pulley 2 is connected to the belt 511 for transmission.

[0029] A fixing plate 6 is fixedly connected to the side wall of the drive box 2. The fixing plate 6 is fixedly connected to the collection box 510. The collection box 510 is located directly below the arc brush 509 and collects the debris swept down.

[0030] The drive wheel 3 is movably connected to the top of the ground rail body 4. The ground rail body 4 is fixed on the ground. The drive motor makes the drive wheel 3 rotate, causing the drive box 2 and the robotic arm 1 to move along the ground rail body 4.

[0031] Under the influence of gravity, the graphite column 503 comes into contact with the drive wheel 3. As the drive wheel 3 rolls on the ground rail, it slightly rubs against the surface of the graphite column 503. This friction causes a small amount of graphite particles on the surface of the graphite column 503 to fall off and land directly on the rolling surface of the drive wheel 3 in contact with the rail, forming a thin solid lubricating film between the drive wheel 3 and the ground rail, reducing friction and wear. After the lowest graphite column 503 shortens due to friction, the left end of the uppermost graphite column 503 loses its restraint, and the uppermost graphite column 503... The graphite column 503 falls down and holds the shortened graphite column 503, forming a stable support structure to prevent the graphite column 503 below from shaking or jumping, maintaining stable contact between the drive wheel 3 and the graphite column 503, and ensuring stable lubrication position. The graphite column 503 is installed on the robot and automatically releases lubrication through rolling friction, eliminating the need for frequent refueling or machine shutdown. At the same time, multiple graphite columns 503 are set in the loading rack 501, which can be automatically replenished under the action of gravity, ensuring continuous lubrication without manual intervention and extending the maintenance cycle.

[0032] When the drive box 2 moves on the ground rail body 4, the friction wheel 507 and the ground rail body 4 are relatively displaced, and the friction wheel 507 rotates. Through the transmission of the belt 511, the rotating shaft 508 and the arc brush 509 rotate. The arc brush 509 sweeps the contact surface between the ground rail body 4 and the drive wheel 3, removing dust, iron filings, graphite powder and other impurities, ensuring that the contact surface between the drive wheel 3 and the graphite column 503 and the ground rail body 4 is clean, achieving effective lubrication, reducing frictional resistance and wear rate, and extending the life of the drive wheel 3 and the ground rail body 4.

[0033] In addition, the connecting rod 505 is inserted into the fixing frame 504. A spring 7 is sleeved on the side wall of the connecting rod 505. One end of the spring 7 abuts against the fixing frame 504, and the other end of the spring 7 abuts against the mounting frame 506. The spring 7 pushes the mounting frame 506, so that the friction wheel 507 is pressed against the ground rail body 4. The spring 7 continuously applies force, so that the friction wheel 507 always maintains close contact with the ground rail surface. No matter how uneven or vibrating the ground rail body 4 is, the friction wheel 507 will not loosen, ensuring the normal operation of the drive or cleaning device.

[0034] In this invention, during use, when the drive wheel 3 rolls on the ground rail, it will slightly rub against the surface of the graphite column 503. This friction will cause a small amount of graphite particles on the surface of the graphite column 503 to fall off and directly onto the rolling surface of the drive wheel 3 in contact with the rail, forming a thin solid lubricating film between the drive wheel 3 and the ground rail, reducing friction and wear. After the lowest graphite column 503 is shortened by friction, the left end of the graphite column 503 above it loses its restraint, and the graphite column 503 above it can fall down and hold the shortened graphite column 503, ensuring that the lubrication position is stable. The friction wheel 507 rotates, and through the transmission of the belt 511, it drives the rotating shaft 508 and the arc-shaped brush 509 to rotate. The arc-shaped brush 509 sweeps the contact surface between the ground rail body 4 and the drive wheel 3, removing dust, iron filings, graphite powder and other impurities, ensuring that the contact surface between the drive wheel 3 and the graphite column 503 and the ground rail body 4 is clean and achieving effective lubrication.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
