Description

Technical Field

[0001] This utility model relates to the field of drive setting technology, specifically a drive mechanism for automatically lifting tarpaulins. Background Technology

[0002] To protect cargo from damage, transport vehicles typically cover their roofs with tarpaulins, usually done manually. Some modern systems use automated equipment for this purpose, effectively addressing the safety hazards of working at heights, low efficiency, and high physical exertion associated with traditional manual tarpaulin removal. However, this automated system uses a motor and chain drive, and the chain assembly lacks an automatic oiling mechanism. During use, friction between the chain and gears / sprockets intensifies, leading to accelerated chain wear. Over time, severe chain wear reduces the system's lifespan. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a drive mechanism for automatically lifting tarpaulins, comprising: a support frame 1; a transmission connection located in the middle of the support frame 1, the transmission assembly including a first transmission shaft 5 and a second transmission shaft 8 rotatably mounted in the middle of the support frame 1, sprockets evenly mounted on the outer sides of the first transmission shaft 5 and the second transmission shaft 8, the two sprockets being connected by a chain 16; a drive unit located on the top of the support frame 1, the drive unit including a motor 4 for driving the first transmission shaft 5; an oiling assembly located on one side of the chain 16, the oiling assembly including a brush 10 rubbed against the chain 16 and an oil storage pipe 12 for supplying oil to the brush 10, a piston rod 15 inside the oil storage pipe 12, a repulsive part being provided at the top of the piston rod 15 for reciprocatingly driving the piston rod 15 to squeeze out the oil inside the oil storage pipe 12.

[0024] It should be noted that when this utility model is working, the motor 4 drives the transmission shaft 5 to rotate, and the transmission shaft 5 drives the transmission shaft 8 to rotate through the chain 16. During this period, the chain 16 rubs against the brush 10, and the repulsive part drives the piston rod 15 to make piston movement in the oil storage pipe 12, so that the oil inside the oil storage pipe 12 is intermittently sprayed onto the brush 10, thereby applying oil to the chain 16 through the brush 10, thus continuously providing lubrication to the chain 16 and reducing the friction and wear of the chain during operation.

[0025] The support frame 1 is fixedly connected to the top of the upper support plate 2, the upper support plate 2 is fixedly connected to the top of the reducer 3, the drive shaft 5 is fixedly connected to the output end of the reducer 3, the motor 4 is fixedly connected to the input end of the reducer 3, the middle of the support frame 1 and below the upper support plate 2 is fixedly connected to the lower support plate 7, and the drive shaft 8 is rotatably installed on the top of the lower support plate 7.

[0026] It should be noted that when this utility model is working, the reducer 3 is a worm gear reducer, the motor 4 drives the transmission shaft 5 to rotate through the reducer 3, the transmission shaft 5 drives the chain 16 to move through the sprocket on its outer side, the chain 16 drives the transmission shaft 8 to rotate through the sprocket, and the transmission shaft 8 is connected to the load for driving operation.

[0027] The bottom support plate 7 is fixedly connected to the top of the brush box 9, the brush 10 is fixed to the inner wall of the brush box 9, and one end of the chain 16 is placed inside the brush box 9.

[0028] It should be noted that the brush 10 of this utility model is fixed to the inner wall of the oiling box 9 and directly contacts the chain 16. The brush evenly applies the lubricating oil inside the oiling box 9 to the chain 16, ensuring continuous lubrication of the chain during operation. When one end of the chain 16 moves inside the oiling box 9, the friction between the brush 10 and the chain evenly applies the lubricating oil to the surface of the chain, ensuring good lubrication of the entire chain system. The oiling box 9 can also recycle oil, collecting excess oil on the chain to prevent oil spillage, waste, and pollution.

[0029] The repulsive part includes magnet 6 and magnet 13. The oil storage pipe 12 is threaded to the bottom of the upper support plate 2. The top of the piston rod 15 is fixedly connected to magnet 13. The end of the transmission shaft 5 and the top of magnet 13 is fixedly connected to magnet 6 with a semi-circular structure. The outer wall of magnet 6 has the same magnetic pole as the top of magnet 13. The bottom of the oil storage pipe 12 is fixedly connected to two one-way valves 18 for air intake and oil output. The one-way valve 18 for oil output is connected to brush 10 through oil supply pipe 11. The bottom of magnet 13 is fixedly connected to two limiting slide rods 14. The limiting slide rods 14 are slidably connected to the upper support plate 2. A spring 17 is installed inside the oil storage pipe 12.

[0030] It should be noted that in this invention, when the motor 4 drives the transmission shaft 5 to rotate via the reducer 3, the transmission shaft 5 drives the magnet 6 to rotate. When the magnet 6 approaches the magnet 13, under the action of repulsion, the magnet 13 drives the limiting slide rod 14 and the piston rod 15 to move downward. The piston rod 15 moves into the oil storage pipe 12 and compresses the spring 17, thereby transporting the oil inside the oil storage pipe 12 to the brush 10 through the oil outlet check valve 18 and the oil delivery pipe 11. The brush 10 then applies the oil to the outside of the chain 16. When the magnet 6 separates from the magnet 13, the spring 17 drives the piston rod 15 to move the magnet 13 upward. During this period, the oil storage pipe 12 draws in outside air through the air inlet check valve 18, thus circulating and reciprocating to apply oil to the brush 10, facilitating the application of the oil to the chain 16.
