Description

Technical Field

[0001] This invention belongs to the field of lubrication system technology, specifically an automatic lubrication system. Background Technology

[0002] In a walking system, a common walking structure is that a motor drives a gear to rotate, and the gear meshes with a walking rack. When the motor rotates, it can move along the walking rack to achieve the walking function.

[0003] When the walking system is running, the walking rack is mostly exposed. Due to the interaction between the gear and the walking rack, the rack will wear out significantly and is prone to rust. Therefore, it is necessary to replenish the lubricant regularly. The use of lubricant can not only make the meshing of the gear and the walking rack smoother, but also prevent the rack from rusting.

[0004] However, in the existing technology, most coating is done manually, while this application proposes an automatic lubrication system. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides an automatic lubrication system, which effectively solves the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic lubrication system, comprising a lubrication device and a traveling gear, the traveling gear passing through the lubrication device, the traveling gear having a convex cross-section, and a through hole provided on the lubrication device for the traveling gear to pass through.

[0007] The lubrication device includes a housing with a through hole on its surface. Inside the housing is a container for holding lubricating fluid. A nozzle is located at the lower end of the container, and a pressurization structure is installed inside the container.

[0008] The housing is equipped with rotatable rollers. The lower end of the rollers presses against the stepped surface of the traveling gear, and when the rollers rotate, the housing can move along the traveling gear.

[0009] The housing is also equipped with a movable block. The lower end of the movable block has a toothed surface that meshes with the traveling gear. When the housing moves along the traveling gear, the movable block can move with the housing and can also move laterally along the traveling gear.

[0010] Preferably, a drive motor is also installed on the side of the housing, which drives the roller to rotate. A transmission wheel is also fixedly connected to the output end of the drive motor. The transmission wheel is located inside the inner wall of the housing. The moving block is installed on the guide rail. A rack is provided at the lower end of the guide rail. The transmission wheel is externally provided with a first gear. The first gear meshes with the rack so that when the drive motor drives the transmission wheel to rotate, the transmission wheel can drive the guide rail to move.

[0011] Preferably, a sliding groove is provided on the inner wall of the housing, the guide rail is fixedly connected to the fixed rod, the rack is located on the lower end face of the fixed rod, a lead screw passes through the fixed rod and the guide rail, a slider is fixedly connected to the moving block, the slider is inserted into the guide rail, and the lead screw and the slider are threadedly engaged, one end of the lead screw extends out of the fixed rod, and a traveling gear is fixedly connected to this end, and a fixed rack is provided on the lower side wall of the sliding groove so that the lead screw can rotate when the fixed rod slides.

[0012] Preferably, an intermediate wheel is also provided in the side wall of the box body. The intermediate wheel is fixed to the fixed frame. A support block is fixed to the lower end of the fixed frame, and the lower end surface of the support block is an inclined surface. A bracket is also fixed to the fixed frame. A rotating wheel is rotatably provided on the bracket. A first actuating frame and a second actuating frame are also fixed to the fixed frame. The ends of the first actuating frame and the second actuating frame extend to both ends of the slide groove, respectively.

[0013] When the fixed rod slides to one end of the slide groove, the fixed rod can push the second actuating frame to one side, thereby causing the fixed frame to slide. At this time, the rotating wheel can push the fixed rod upward and cause the transmission wheel to disengage from the rack, and the intermediate wheel can mesh with the transmission wheel and the rack respectively, thereby causing the fixed rod to move in the opposite direction.

[0014] When the fixed rod moves to the other end of the slide, the fixed rod can push the first actuating frame to the other side, causing the fixed frame to slide. At this time, the intermediate wheel can disengage from the transmission wheel and the rack respectively, and the transmission wheel meshes with the rack, causing the fixed rod to reciprocate.

[0015] Preferably, a limiting block is fixed to the side of the second actuating frame, and a limiting groove is opened in the inner wall of the housing. There are two limiting grooves, and the two limiting grooves are arranged side by side. The limiting block is elastic, and a first spring is provided on one side of the second actuating frame.

[0016] Preferably, the container has a pressure plate that can move up and down, and a hydraulic rod is provided at the upper end of the pressure plate.

[0020] 2) By setting up guide rails, transmission wheels, racks, lead screws, etc., the traveling rack can be cleaned so that it can be coated with lubricating oil and ensure its normal and stable use in the future.

[0021] 3) By setting up a container, it can hold lubricating oil, and with the use of a pressurization structure, it can also easily apply lubricating oil to the traveling gears. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Depend on Figure 1-9 The present invention discloses an automatic lubrication system, including a lubrication device 100 and a traveling gear 200. The traveling gear 200 passes through the lubrication device 100, and the cross-section of the traveling gear 200 has a convex shape. A through hole is provided on the lubrication device 100 for the traveling gear 200 to pass through, and the shape of the through hole is adapted to the shape of the traveling gear 200.

[0035] The lubrication device 100 includes a housing 1 with a through hole on its surface. Inside the housing 1 is a container 3 for holding lubricating oil. A nozzle 24 is located at the lower end of the container 3, and a pressurizing structure is installed inside the container 3. When the housing 1 moves along the traveling gear 200, the pressurizing structure applies pressure to the container 3, causing the lubricating oil to flow out of the container 3 and fall onto the traveling gear 200.

[0036] A rotatable roller 6 is installed inside the housing 1. The lower end face of the roller 6 presses against the stepped surface of the traveling gear 200. When the roller 6 rotates, the housing 1 can move along the traveling gear 200. The roller 6 cooperates with the traveling gear 200, that is, when the roller 6 rotates, the housing 1 can move along the traveling gear 200.

[0037] The housing 1 is also equipped with a movable block 5. The lower end of the movable block 5 has a toothed surface that meshes with the traveling gear 200. When the housing 1 moves along the traveling gear 200, the movable block 5 can move together with the housing 1, and the movable block 5 can also move laterally along the traveling gear 200.

[0038] During the first stage of the housing 1 moving along the traveling gear 200, the moving block 5 can be relatively stationary with the traveling gear 200 in the traveling direction of the housing 1. During this process, the moving block 5 can move in a direction perpendicular to the traveling direction of the housing 1, thereby clearing the gaps in the traveling gear 200 to a certain extent.

[0039] In the second stage of the movement of the housing 1 along the traveling gear 200, the moving block 5 separates from the traveling rack 200. At this time, the moving block 5 can return to its initial position inside the housing 1, and then proceed to the first stage of the next motion cycle.

[0040] The number of moving blocks 5 can be set to two. The two moving blocks 5 are located on both sides of the receiving barrel 3. One moving block 5 can clean the traveling rack 200, and the other moving block 5 can coat the lubricating oil evenly.

[0041] A drive motor 2 is also installed on the side of the housing 1. The drive motor 2 drives the roller 6 to rotate, and a transmission wheel 8 is fixedly connected to the output end of the drive motor 2. The transmission wheel 8 is located inside the inner wall of the housing 1. The moving block 5 is installed on the guide rail 4. A rack 18 is provided at the lower end of the guide rail 4. The transmission wheel 8 is externally equipped with a first gear. The first gear meshes with the rack 18 so that when the drive motor 2 drives the transmission wheel 8 to rotate, the transmission wheel 8 can drive the guide rail 4 to move. When the drive motor 2 is running, it can drive the transmission wheel 8 and the roller 6 to rotate. When the transmission wheel 8 rotates, it can mesh with the rack 18, thereby causing the guide rail 4 to move. At this time, the guide rail 4 and the traveling gear 200 are in a relatively stationary state, so that the moving block 5 can clean the traveling rack 200 and prevent the moving block 5 and the traveling rack 200 from jamming.

[0042] A sliding groove is provided on the inner wall of the housing 1. The guide rail 4 is fixedly connected to the fixed rod 9. The rack 18 is located on the lower end face of the fixed rod 9. A lead screw 16 passes through the fixed rod 9 and the guide rail 4. A slider 17 is fixedly connected to the moving block 5. The slider 17 is inserted into the guide rail 4, and the lead screw 16 and the slider 17 are threaded together. One end of the lead screw 16 extends out of the fixed rod 9, and a traveling gear 15 is fixedly connected to this end. A fixed rack is provided on the lower side wall of the sliding groove so that the lead screw 16 can rotate when the fixed rod 9 slides.

[0043] When the fixed rod 9 moves, the drive gear 15 can mesh with the fixed rack, causing the drive gear 15 to rotate. When the drive gear 15 rotates, the lead screw 16 can rotate with it. The lead screw 16 passes through the slider 17, but the slider 17 cannot rotate with the lead screw 16, so that the slider 17 can move along the lead screw 16, thereby driving the moving block 5 to slide, so that the moving block 5 can clean the traveling rack 200.

[0044] An intermediate wheel 10 is also provided in the side wall of the housing 1. The intermediate wheel 10 is fixed to the fixed frame 11. A support block 21 is fixed to the lower end of the fixed frame 11. The lower end surface of the support block (21) is an inclined surface. A bracket is also fixed to the fixed frame 11. A rotating wheel 20 is rotatably provided on the bracket. A first actuating frame 12 and a second actuating frame 13 are also fixed to the fixed frame 11. The ends of the first actuating frame 12 and the second actuating frame 13 extend to both ends of the slide groove, respectively.

[0045] During one movement of the fixed rod 9, it can be decomposed into two segments.

[0046] First section: When the fixed rod 9 slides from the initial position to one end of the slide groove, the fixed rod 9 can push the second actuating frame 13 to one side, thereby causing the fixed frame 11 to slide. At this time, the rotating wheel 20 can push the fixed rod 9 upward, causing the transmission wheel 8 to disengage from the rack 18, and the intermediate wheel 10 can mesh with the transmission wheel 8 and the rack 18 respectively. At this time, the transmission wheel 8 first drives the intermediate wheel 10 to rotate, and the intermediate wheel 10 then drives the fixed rod 9 to move, causing the fixed rod 9 to move in the opposite direction.

[0047] When the fixed rod 9 moves to the other end of the slide, the fixed rod 9 can push the first actuating frame 12 to the other side, thereby causing the fixed frame 11 to slide. At this time, the intermediate wheel 10 can disengage from the transmission wheel 8 and the rack 18 respectively, and the transmission wheel 8 meshes with the rack 18, thereby causing the fixed rod 9 to reciprocate.

[0048] The second actuating frame 13 has a limiting block 23 fixedly attached to its side, and two limiting grooves 22 are formed in the inner wall of the housing 1. The two limiting grooves 22 are arranged side by side. The limiting block 23 is elastic, and a first spring 14 is provided on one side of the second actuating frame 13. When the second actuating frame 13 is initially actuated, the fixed frame 11 will not move. When the thrust of the second actuating frame 13 reaches a certain value, the second actuating frame 13 can be pushed. At this time, the limiting block 23 can quickly slide from one limiting groove 22 into the other limiting groove 22.

[0049] The container 3 has a pressure plate 25 that can move up and down. A hydraulic rod 26 is provided at the upper end of the pressure plate 25. The fixed end of the hydraulic rod 26 is fixed to the box 1, and the telescopic end of the hydraulic rod 26 is fixed to the pressure plate 25. The container 3 is fixed inside the box 1. The hydraulic rod 26 and the pressure plate 25 form a pressure structure.

[0050] Scrapers 7 are also fixed to the inner wall of the housing 1. Each side of the housing 1 has a set of scrapers 7 on its inner wall. The two scrapers 7 in the same set are arranged symmetrically and are inclined. When the scrapers 7 move with the housing 1, they can scrape off the impurities on the traveling rack 200.
