[0002] Steel strand, as a high-strength, high-toughness prestressed steel product, plays a vital role in modern engineering construction. It is made of multiple high-carbon steel wires twisted together according to a certain rule. This unique structural design not only greatly enhances the tensile strength of the material, but also improves its flexibility and fatigue resistance, making it an indispensable material in many fields such as bridges, large-span buildings, roads, railways, mine support, and power transmission lines. Steel strand needs to be coated with lubricating oil through an oiling device during production to reduce the occurrence of rust on the steel strand.

[0003] The existing oiling device is basically composed of a frame, an atomizing nozzle and two steel strand retractors. The two steel strand retractors are used to transport the steel strands inside the frame. During the transportation process, the atomizing nozzle will spray lubricating oil on the steel strands. To ensure the effect of lubricating oil spraying, the atomizing nozzle will spray a large amount of lubricating oil on the steel strands, and some of the excess lubricating oil will gather on the steel strands and gather into water droplets at the bottom of the steel strands. The water droplets of lubricating oil at the bottom of the steel strands will drip onto the frame when being transported by the steel strand retractor. This situation causes waste of lubricating oil and reduces the utilization rate of lubricating oil to a certain extent.

[0004] Therefore, it is necessary to provide a new steel strand oiling device to solve the above technical problems. Utility Model Content

The vertical height of the oil inlet groove 6 is higher than the vertical height of the oil outlet groove 7. A second guide block 8 is movably provided on the top of the first guide block 4. A movable groove 10 is provided inside the frame 1. The top of the second guide block 8 extends to the inside of the movable groove 10. A support block 9 is movably provided inside the movable groove 10. The top of the second guide block 8 is fixedly connected to the bottom of the support block 9. Two first springs 11 are fixedly provided on the top of the support block 9. The tops of the two first springs 11 are fixedly connected to the inside of the movable groove 10.

[0024] The lubricating oil in the storage tank 5 can be filled in advance, or collected by the water droplet-shaped lubricating oil gathered at the bottom of the steel strand. In either case, when the lubricating oil collected in the storage tank 5 reaches a certain level, when the lubricating oil enters the oil inlet tank 6 again, the lubricating oil in the storage tank 5 will be driven to move toward the oil outlet, so that the lubricating oil lubricates the bottom of the steel strand.

[0025] A first movable block 12 is fixedly provided on the side of the frame 1 away from the first guide block 4, a second movable block 13 is movably provided on the top of the first movable block 12, the top of the second movable block 13 extends into the movable groove 10, the outer surface of the second movable block 13 is movably connected to the inner surface of the movable groove 10, a fixed block 14 is movably provided inside the movable groove 10, the bottom of the fixed block 14 is fixedly connected to the top of the second movable block 13, two second springs 15 are fixedly provided on the top of the fixed block 14, the tops of the two second springs 15 are fixedly connected to the inside of the movable groove 10, a connecting block 16 is movably provided inside the movable groove 10, both sides of the connecting block 16 are respectively fixedly connected to the fixed block 14 and the opposite side of the support block 9, the movable groove 10 is filled with hydraulic oil, a plurality of circular grooves 17 are provided on the top of the connecting block 16, and the edges of the first movable block 12 and the second movable block 13 on the side away from the first guide block 4 are chamfered respectively;

[0026] When one of the steel strand take-up and unwinding devices 2 delivers the steel strand to another steel strand take-up and unwinding device 2, the steel strand will pass between the first movable block 12 and the second movable block 13, and between the first guide block 4 and the second guide block 8, and finally be delivered to other equipment through another steel strand take-up and unwinding device 2. When the steel strand is delivered inside the frame 1, the atomizing nozzle 3 located between the second movable block 13 and the second guide block 8 will spray lubricating oil on the steel strand, and part of the sprayed lubricating oil will converge on the steel strand. , a drop-shaped lubricating oil is formed at the bottom of the steel strand. When the steel strand passes between the first guide block 4 and the second guide block 8, the drop-shaped lubricating oil gathered at the bottom of the steel strand enters the first guide block 4 through the oil inlet groove 6 into the storage groove 5 of the first guide block 4. Since the vertical level of the oil inlet groove 6 is higher than the vertical level of the oil outlet groove 7, when the steel strand is about to leave the guide block, the lubricating oil inside the storage groove 5 will flow out from the oil outlet groove 7 to lubricate the bottom of the steel strand;

[0027] The outer surfaces of the second movable block 13 and the second guide block 8 are respectively provided with square sealing gaskets 18, and the top ends of the two square sealing gaskets 18 are fixedly connected to the inside of the frame 1. The two square sealing gaskets 18 prevent the hydraulic oil inside the movable groove 10 from leaking. When it is necessary to lubricate the steel strand of a new diameter, after the steel strand of the new diameter enters between the first movable block 12 and the second movable block 13 and the first guide block 4 and the second guide block 8, the steel strand drives the second movable block 13 and the second guide block 8 to move upward respectively, and the second movable block 13 and the second guide block 8 drive the fixed block respectively. 14 and the support block 9 move upward, so that the fixed block 14 and the support block 9 simultaneously drive the connecting block 16 to move upward. When the connecting block 16 moves upward, the connecting block 16 squeezes the hydraulic oil in the movable groove 10 of the frame 1, causing the pressure of the hydraulic oil to change. The pressure drives the hydraulic oil to flow downward from the circular groove 17 of the connecting block 16. When the hydraulic oil flows in the circular groove 17, friction is generated. The friction generated reduces the kinetic energy of the steel strand passing through the first movable block 12 and the second movable block 13 and the first guide block 4 and the second guide block 8, thereby improving the steel strand. The stranded wire is stable when passing through the first movable block 12 and the second movable block 13 and between the first guide block 4 and the second guide block 8. At the same time, the structure can provide limited support for steel strands of different diameters. When the second movable block 13 and the second guide block 8 move upward, the second movable block 13 and the second guide block 8 respectively drive the first spring 11 and the second spring 15 to move upward, driving the first spring 11 and the second spring 15 to be in a compressed state. When the steel strand is lubricated and leaves the frame 1, the drive to the first spring 11 and the second spring 15 is released. The first spring 11 and the second spring 15 respectively extend, and the first spring 11 and the second spring 15 respectively drive the second movable block 13 and the second guide block 8 to move downward through the fixed block 14 and the support block 9, completing the resetting of the second movable block 13 and the second guide block 8. Because the edges of one side of the first movable block 12 and the second movable block 13 are chamfered respectively, this structure facilitates the steel strand to enter between the first movable block 12 and the second movable block 13, and the steel strand retractor 2 can realize the passage of steel strands of different diameters through the control of the staff.
