Description
Technical Field
[0001] This utility model relates to the field of double-layer ground rail conveyor chains, specifically a double-layer ground rail conveyor chain structure. Background Technology
[0002] Double-layer ground rail conveyor is a chain conveying system that utilizes a double-layer track layout. The chain is driven to circulate in the upper and lower spaces through underground or ground-mounted tracks, achieving bidirectional and efficient conveying of objects. It is suitable for industrial scenarios where space is limited but high-density conveying is required.
[0003] Existing double-layer ground rail conveyor chain structures typically use sprockets and roller chains. The rotation of the sprockets drives the roller chains to transmit materials. However, after prolonged use, the roller chains require lubrication. Lubricating oil needs to be applied to the roller chains, but because the roller chains are located inside the track, applying lubricating oil is troublesome for workers, thus reducing the lubrication efficiency of the roller chains. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a double-layer ground rail type conveyor chain structure to solve the technical problem of poor lubrication efficiency of roller chains.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-layer ground rail type conveyor chain structure, including a first conveyor frame, a support frame fixed on the first conveyor frame, and a second conveyor frame installed on the top of the support frame. The first and second conveyor frames are provided with a lubrication assembly, which includes a fixing plate installed on the outer surface and back of the first and second conveyor frames. A movable shaft is connected to the top of the fixing plate via a bearing, and a rotating plate is installed at the top of the movable shaft. A worm gear is installed on the outer wall of the movable shaft. Two side plates are also installed on the top of the fixing plate, and worm gears are connected to the side plates via bearings. An oil storage tank is fixed to the bottom of the rotating plate, and multiple oil drip holes are opened at the bottom of the oil storage tank. A movable plate is slidably arranged inside the oil storage tank, and multiple sealing plugs extending into the oil drip holes are installed at the bottom of the movable plate.
[0006] By adopting the above technical solution, when the movable plate moves up and drives the sealing plug to move up, the lubricating oil in the oil tank will flow out from the oil dripping hole when the sealing plug moves out of the oil dripping hole.
[0007] Furthermore, a return spring is installed inside the upper part of the oil tank, and the bottom end of the return spring is connected to the top of the movable plate.
[0008] By adopting the above technical solution, when the movable plate moves up, it will squeeze the return spring, causing the return spring to be compressed by force, which facilitates the subsequent pushing of the movable plate down to reset.
[0009] Furthermore, a pull rod is fixed to the top of the movable plate, penetrating the oil tank and the rotating plate.
[0010] By adopting the above technical solution, it is convenient for staff to move the movable plate by pulling the lever, and the movable plate will move the sealing block when it moves.
[0011] Furthermore, the top of the oil storage tank is connected to an oil inlet pipe that penetrates the rotating plate, and the top end of the oil inlet pipe is threaded with a sealing cap.
[0012] By adopting the above technical solution, the sealing cap can block the oil inlet pipe and prevent external impurities from entering the interior of the oil storage tank through the oil inlet pipe.
[0013] Furthermore, a handle is installed at one end of the worm, and the worm meshes with a worm wheel.
[0014] By adopting the above technical solution, it is convenient for the staff to rotate the worm gear by turning the handle. The rotation of the worm gear will drive the worm wheel to rotate, which in turn drives the movable shaft to rotate.
[0015] Furthermore, a sealing ring made of rubber material is provided between the pull rod and the oil tank, and the rotating plate is rotatably connected to the fixed plate through a movable shaft.
[0016] By adopting the above technical solution, the movable shaft is designed to facilitate the rotation of the rotating plate, which in turn drives the oil tank to rotate.
[0017] Furthermore, the sealing plug is adapted to the drip hole, and the outer wall of the sealing plug is provided with a sealing ring made of rubber material.
[0018] By adopting the above technical solution, once the sealing plug is inserted into the oil drip hole, the oil drip hole can be sealed, preventing the lubricating oil inside the oil tank from flowing out at will.
[0019] Furthermore, both the first and second conveyor frames have tracks on their tops, and the tracks are connected to a rotating shaft via bearings, with a driven sprocket mounted on the outer wall of the rotating shaft.
[0020] By adopting the above technical solution, the shaft is designed to facilitate the rotation of the driven sprocket.
[0021] Furthermore, servo motors are installed on one side of the outer surface and one side of the back of the first conveyor frame and on one side of the outer surface and one side of the back of the second conveyor frame, and the output end of the servo motor is connected to a drive sprocket.
[0022] By adopting the above technical solution, when the sheet material needs to be conveyed, the servo motor can be started, and the servo motor can drive the drive sprocket to rotate.
[0023] Furthermore, the driving sprocket is located inside the track, and a roller chain is fitted between the driving sprocket and the driven sprocket.
[0024] By adopting the above technical solution, the rotation of the drive sprocket can drive the rotation of the roller chain, thereby enabling the roller chain to transport the sheet metal.
[0025] In summary, the present invention has the following main advantages:
[0026] 1. This utility model, by incorporating a lubrication assembly, allows the operator to rotate the worm gear via a handle when lubrication of the roller chain is required. The rotation of the worm gear drives the worm wheel to rotate, which in turn drives the movable shaft to rotate. The movable shaft then drives the rotating plate to rotate, which in turn drives the oil reservoir to rotate. When the oil reservoir rotates to directly above the roller chain, the operator stops rotating the worm gear and pulls the lever upward. The lever then pulls the movable plate upward, which in turn moves the sealing plug upward. When the sealing plug moves out of the drip hole, the lubricating oil in the oil reservoir flows out from the drip hole and drips onto the roller chain, thus lubricating the roller chain. Furthermore, the dripping of lubricating oil causes the roller chain to move, thereby improving the lubrication efficiency of the roller chain.
[0027] 2. The worm and worm wheel of this utility model have self-locking properties. The worm wheel will not rotate when the worm is not rotated, thereby preventing the rotating plate from rotating arbitrarily and improving the stability of the rotating plate. By setting a return spring, it is convenient to push the movable plate down to reset later.
[0028] 3. This utility model has a sealing plug. When the sealing plug is inserted into the oil drip hole, it can seal the oil drip hole and prevent the lubricating oil inside the oil tank from flowing out at will. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0039] The embodiments of this utility model will be described below based on its overall structure.
[0040] Example 1:
[0041] A double-layer ground rail type conveyor chain structure, such as Figures 1-8 As shown, the system includes a first conveyor frame 1, a support frame 2 fixed on the first conveyor frame 1, and a second conveyor frame 3 mounted on the top of the support frame 2. Lubrication components 9 are provided on both the first and second conveyor frames 1 and 3. Tracks 10 are provided on the top of both the first and second conveyor frames 1 and 3. A rotating shaft 7 is connected to the inside of the track 10 via bearings, and a driven sprocket 8 is mounted on the outer wall of the rotating shaft 7. The rotating shaft 7 facilitates the rotation of the driven sprocket 8. Servo motors 4 are mounted on one side of the outer surface and one side of the back of the first conveyor frame 1 and one side of the outer surface and one side of the back of the second conveyor frame 3, and the output ends of the servo motors 4 are connected to… There is a drive sprocket 5. When it is necessary to transport the board, the servo motor 4 can be started. The servo motor 4 can drive the drive sprocket 5 to rotate. The drive sprocket 5 is located inside the track 10. A roller chain 6 is sleeved between the drive sprocket 5 and the driven sprocket 8 so that when the drive sprocket 5 rotates, it can drive the roller chain 6 to rotate, thereby enabling the roller chain 6 to transport the board. The top height of the roller chain 6 on the first conveyor frame 1 is higher than the top height of the first conveyor frame 1, and the top height of the roller chain 6 on the second conveyor frame 3 is higher than the top height of the second conveyor frame 3, so that the roller chain 6 can transport the object when it rotates.
[0042] Specifically, the lubrication assembly 9 includes a fixed plate 901 installed on the outer surface and back of the first conveyor frame 1 and the outer surface and back of the second conveyor frame 3. A movable shaft 904 is connected to the top of the fixed plate 901 via a bearing, and a rotating plate 906 is installed at the top of the movable shaft 904. A worm gear 905 is installed on the outer wall of the movable shaft 904. Two side plates 902 are also installed on the top of the fixed plate 901, and worm gears 903 are connected to the side plates 902 via bearings. The bottom of the 06 is fixed with an oil reservoir 907, and the bottom of the oil reservoir 907 is provided with multiple oil drip holes 913. A movable plate 912 is slidably arranged inside the oil reservoir 907. Multiple sealing plugs 914 extending into the oil drip holes 913 are installed at the bottom of the movable plate 912. When the movable plate 912 moves upward and drives the sealing plugs 914 to move upward, the sealing plugs 914 move out of the oil drip holes 913, and the lubricating oil in the oil reservoir 907 will flow out from the oil drip holes 913.
[0043] See Figures 1-6 A pull rod 911 is fixed to the top of the movable plate 912, passing through the oil tank 907 and the rotating plate 906, allowing the operator to move the movable plate 912 by pulling the pull rod 911. When the movable plate 912 moves, it will drive the sealing plug 914 to move. A handle is installed at one end of the worm 903, and the worm 903 meshes with the worm wheel 905, allowing the operator to rotate the worm 903 by rotating the handle. The rotation of the worm 903 will drive the worm wheel 905 to rotate, which in turn will drive the movable shaft 904 to rotate. The pull rod 911 and the oil tank 907 are connected. A sealing ring made of rubber is provided between the two. The rotating plate 906 is rotatably connected to the fixed plate 901 via the movable shaft 904. The movable shaft 904 facilitates the rotation of the rotating plate 906. The rotation of the rotating plate 906 will drive the oil reservoir 907 to rotate. The sealing plug 914 is adapted to the oil drip hole 913. The outer wall of the sealing plug 914 is provided with a sealing ring made of rubber. When the sealing plug 914 is inserted into the oil drip hole 913, it can seal the oil drip hole 913 and prevent the lubricating oil inside the oil reservoir 907 from flowing out at will.
[0044] Example 2:
[0045] Based on the above embodiment 1, the following structure will be set to enable the movable plate 912 to be quickly reset.
[0046] Specifically, a return spring 910 is installed inside the upper part of the oil tank 907. The bottom end of the return spring 910 is connected to the top of the movable plate 912. When the movable plate 912 moves upward, it will squeeze the return spring 910, so that the return spring 910 is compressed and can be pushed down to reset.
[0047] Example 3:
[0048] Based on the above embodiment 1, the following structure will be set up to facilitate the addition of lubricating oil into the oil reservoir 907.
[0049] See Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 The top of the oil reservoir 907 is connected to an oil inlet pipe 908 that passes through the rotating plate 906. The top of the oil inlet pipe 908 is threaded with a sealing cap 909. The sealing cap 909 can block the oil inlet pipe 908 to prevent external impurities from entering the interior of the oil reservoir 907 through the oil inlet pipe 908. When it is necessary to add lubricating oil to the oil reservoir 907, the operator can rotate the sealing cap 909 to unscrew the sealing cap 909 from the oil inlet pipe 908, and then the lubricating oil can be added to the oil reservoir 907 through the oil inlet pipe 908.
[0050] The working principle of this utility model is as follows: First, when using it, the power can be turned on. When it is necessary to transport objects, the staff can start the servo motor 4. The servo motor 4 can drive the active sprocket 5 to rotate, which in turn drives the roller chain 6 to rotate. The objects can be placed on the roller chain 6 and transported through the roller chain 6. Both the upper and lower layers transport objects through the roller chain 6.
[0051] After prolonged operation, the roller chain 6 requires lubrication. At this time, the operator can rotate the worm 903 using the handle. The rotation of the worm 903 drives the worm wheel 905, which in turn drives the movable shaft 904. The movable shaft 904 then drives the rotating plate 906, which in turn drives the oil reservoir 907. When the oil reservoir 907 is directly above the roller chain 6, the operator stops rotating the worm 903 and pulls the lever 911 upwards. The lever 911 then moves the movable plate 912 upwards, which in turn moves the sealing plug 914 upwards. When the sealing plug 914 drips from the oil drip hole 9... When the oil tank 907 is removed, the lubricating oil in the oil reservoir 907 will flow out from the drip hole 913 to drip onto the roller chain 6. The dripping of lubricating oil will drive the roller chain 6, thereby lubricating it. After the roller chain 6 is lubricated, the operator releases the pull rod 911. At this time, the movable plate 912 drives the sealing plug 914 to move down and reset, and locks into the drip hole 913 to seal the drip hole 913, thereby preventing the lubricating oil in the oil reservoir 907 from flowing out at will. Then, the worm gear 903 is rotated in the opposite direction, so that the rotating plate 906 resets and rotates, and drives the oil reservoir 907 to reset and rotate, so as to prevent the oil reservoir 907 from obstructing the transmission of objects.
