Description

Technical Field

[0001] The utility model belongs to the technical field of winders and provides a lifting mechanism for a winder. Background Art

[0002] The coiler replaces manual winding of steel coils. An electric motor drives the unwinding wheel, which unwinds the coiled steel and transfers it to the reel. The finished steel coils are then reeled into bundles for easy transportation and sale. As the outer diameter of the steel coil increases during the rewinding process, the distance between the reel and the unwinding wheel needs to be increased. After unloading, the reel needs to be reset, requiring a lifting mechanism installed on the coiler to raise and lower the reel.

[0003] The long-term sliding of the lifting block along the surface of the lifting support will cause wear, and the dust in the air will fall onto the surface of the lifting block. The dust particles will accumulate on the surface of the guide column, increasing the friction of the lifting block sliding along the surface of the guide column, resulting in the lifting block sliding unsmoothly, making it impossible for the winding frame to rise and fall smoothly, and the winding frame cannot approach or move away from the unwinding wheel in time, which can easily cause mechanical failure. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and solve the problem that the lifting mechanism of the existing winder may not slide smoothly up and down due to the accumulation of dust particles in the air.

[0006] A lifting platform is installed at the upper end of the fuselage, and a plurality of guide columns are provided at the front end of the lifting platform. A lifting block is inserted between the plurality of guide columns and is slidably connected to the front end of the lifting platform. The lifting block is slidably connected to the guide columns, and a groove is provided at the front end of the lifting block.

[0007] The inner wall of the groove is respectively provided with a plurality of smearing cavities distributed up and down, and the upper end of each smearing cavity is provided with a guide groove located on the inner wall of the groove, the guide groove is perpendicular to the adjacent smearing cavity, the guide groove corresponds to the front of the adjacent guide column one by one, and the guide groove and the smearing cavity pass through the rear end of the lifting block backward;

[0008] The front end of the lifting block is detachably connected to a concave cover embedded in the groove, an oil tank is installed on the upper end of the concave cover, and a throttle valve is installed between the oil tank and the concave cover.

[0009] In a better technical solution of the present invention, a lifting support is installed at the front end of the concave cover, a winding frame is installed at the right end of the lifting support, the rear end of the winding frame is tilted downward at an angle of forty to forty-five degrees, and the rear end of the winding frame is detachably connected to a winding shaft, and a reeling wheel is provided below the winding shaft and installed at the right end of the fuselage.

[0010] In a preferred technical solution of the present invention, a push-pull rod is installed at the lower end between the lifting block and the concave cover, and the lower end of the push-pull rod is transmission-connected to a hydraulic push rod installed on the surface of the fuselage.

[0011] In a preferred technical solution of the present invention, limiting plates are fixed at both upper and lower ends between the plurality of guide columns, and two limiting plates are respectively installed at the upper and lower ends of the lifting bracket.

[0012] In a preferred technical solution of the present invention, any two adjacent guide posts are parallel to each other, and the guide posts are parallel to the lifting support.

[0013] In a preferred technical solution of the present invention, lubricating oil is injected into the oil tank, and the throttle valve is respectively connected to the oil tank and the inner wall of the concave cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The hydraulic push rod drives the push-pull rod to slide the lifting block and the concave cover up and down, so that the reeling frame drives the reeling shaft close to or away from the unwinding wheel, and the lubricating oil inside the oil tank is slowly released into the guide groove through the throttle valve. Under the action of gravity, the guide groove flows the lubricating oil into the coating chamber, and the coating chamber applies the lubricating oil to the surface of each guide column. The guide column evenly applies the lubricating oil to the position between the lifting block and the lifting platform to fully ensure that the lifting block and the lifting platform surface are soaked with lubricating oil, and the lifting block can slide smoothly along the surface of the lifting platform. At the same time, the lubricating oil itself can also clean the dust particles between the lifting block and the lifting platform, so as to maintain the smooth lifting effect of the reeling frame, so that the reeling frame can be timely approached or away from the unwinding wheel, thereby improving the sliding accuracy of the lifting mechanism and avoiding mechanical failure of the lifting mechanism due to accumulated dust particles.

The guide groove 10 is perpendicular to the adjacent coating cavity 11, and the guide groove 10 corresponds one-to-one to the front of the adjacent guide column 7. The wiping cavity 11 passes through the rear end of the lifting block 9 backward; a lifting bracket 16 is installed at the front end of the concave cover 13, and a winding frame 5 is installed at the right end of the lifting bracket 16. The rear end of the winding frame 5 is tilted downward at an angle of forty to forty-five degrees. The rear end of the winding frame 5 is detachably connected to the winding shaft 4. A reel 3 mounted on the right end of the fuselage 1 is provided below the reel 4. A push-pull rod 17 is installed at the lower end between the lifting block 9 and the concave cover 13. The lower end of the push-pull rod 17 is transmission-connected with a hydraulic push rod 2 mounted on the surface of the fuselage 1. The hydraulic push rod 2 drives the push-pull rod 17 to slide the lifting block 9 and the concave cover 13 up and down, so that the reel 5 drives the reel 4 close to or away from the reel 3. The front end of the lifting block 9 is detachably connected to the concave cover 13 embedded in the groove 12. The concave cover 1 The front ends of the three pairs of lifting blocks 9 seal the groove 12, and the concave cover 13 seals the guide groove 10 and the smear chamber 11 inside the groove 12. The concave cover 13 plays a sealing and protective role for the groove 12, the guide groove 10 and the smear chamber 11. An oil tank 14 is installed on the upper end of the concave cover 13. A throttle valve 15 is installed between the oil tank 14 and the concave cover 13. Lubricating oil is injected into the oil tank 14. The throttle valve 15 is respectively connected to the inner wall of the oil tank 14 and the concave cover 13. The size of the internal opening of the throttle valve 15 is electrically controlled to control the flow rate of the lubricating oil flowing through the throttle valve 15. The lubricating oil inside the oil tank 14 is released downward along the throttle valve 15 to the position between the groove 12 and the concave cover 13, and the lubricating oil inside the oil tank 14 is slowly released into the guide groove 10 through the throttle valve 15. , under the action of gravity, the guide groove 10 flows the lubricating oil into the coating chamber 11 for convergence, and the lubricating oil flows along the coating chamber 11 to the surface of each corresponding guide column 7, and the guide groove 10 and the coating chamber 11 move up and down as the lifting block 9 slides up and down. As the lifting block 9 slides up and down along each guide column 7, each guide groove 10 and the coating chamber 11 are aligned with different positions on the surface of the guide column 7, and the coating chamber 11 applies the lubricating oil to the surface of each guide column 7.

The guide column 7 will evenly apply the lubricating oil to the position between the lifting block 9 and the lifting platform 6 to fully ensure that the surfaces of the lifting block 9 and the lifting platform 6 are soaked with lubricating oil. The lubricating oil will flush the dust particles during the flow process. At the same time, the dust particles between the lifting block 9 and the lifting platform 6 will be cleaned by relying on the fluidity of the lubricating oil itself. Limiting plates 8 are fixed at the upper and lower ends between the multiple guide columns 7. The two limiting plates 8 are respectively installed at the upper and lower ends of the lifting support 16. The limiting plates 8 block the upper and lower ends between the multiple lifting columns to prevent the lifting block 9 from slipping off the upper and lower ends of the lifting columns, keeping the lifting block 9 sliding smoothly along the surface of the lifting platform 6, prompting the lifting block 9 to slide up and down smoothly, maintaining the smooth lifting effect of the winding frame 5, and making the winding frame 5 close to or away from the unwinding wheel 3 in time, thereby improving the sliding accuracy of the lifting mechanism and avoiding mechanical failure of the lifting mechanism due to accumulated dust particles.
