Abstract
Description
Technical Field
[0001] The utility model relates to a PF line traction chain. Background Art
[0002] PF wire traction chains are exposed to high temperatures and dry environments for extended periods. The pin-chainplate connection bears significant loads, relying solely on the side-mounted oil-air lubrication system to lubricate the pin and the outer surface of the center ring. This system sprays a wide area but provides suboptimal lubrication. This inadequate lubrication increases the friction coefficient at the contact point between the pin and the center ring, significantly shortening the chain's lifespan. Furthermore, residual lubricant accumulates on the chain, forming greasy dirt that drips onto the C-hooks, causing the wire surface to adhere to the greasy dirt. Utility Model Content
[0003] The purpose of the utility model is to solve the problem that chain lubrication only exists on the chain surface, and the connecting parts in the chain structure cannot be fully lubricated, resulting in large chain wear and cracking after long-term stress.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problems is: a steel rolling PF line traction chain lubrication device, including a slide, a chain support frame, and a chain, the chain support frame is slidingly matched with the slide, the chain is suspended below the slide and the top end is connected to the chain support frame, and its characteristic is that: an oil tank is arranged above the slide, a dropper with a valve is arranged on the oil tank, and an oil leakage hole is opened on the slide which passes through the upper and lower parts, the dropper and the oil leakage hole correspond to the chain above and below, and the lubricating oil in the oil tank is lubricated from top to bottom to the chain through the dropper and the oil leakage hole.
[0005] As one of the preferred implementations, a pipe joint is provided at the bottom of the oil tank, and the dropper is connected to the pipe joint so that the dropper can be replaced.
[0006] As one of the preferred implementations, the diameter of the oil leakage hole is 5-8 mm, more preferably 6 mm.
[0007] As one of the preferred embodiments, the device further includes a C-shaped hook, to which the chain is connected, and the C-shaped hook is used to transport the coils. The C-shaped hook is provided with a collection trough for collecting waste oil dripping from the chain, thereby preventing waste oil from accumulating and leaving oil stains on the coil products.
[0008] Compared with the prior art, the advantages of the present invention are as follows: the PF line traction chain lubrication device of the present application uses a method of dripping lubricating oil from above to lubricate the chain below the slide. Compared with the method of spraying lubricating oil from the side of the chain, the method of dripping lubricating oil from above can fully lubricate the connecting parts in the middle and inside of the chain, such as the pin shaft and the inside of the middle ring, so that the chain is in a lubricated state for a long time, thereby reducing the friction force at the stress position, effectively extending the service life of the chain, reducing the risk of chain breakage, and reducing equipment failure. In addition, the top dripping method is more environmentally friendly, economical and convenient for recycling than the side spraying method. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is further described in detail below in conjunction with the accompanying drawings. The embodiments described are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. The textual descriptions in the embodiments correspond to the accompanying drawings, and the descriptions of the directions are also based on the descriptions of the accompanying drawings, and should not be construed as limiting the scope of protection of the present invention.
[0013] like Figure 1 As shown, the steel rolling PF line traction chain lubrication device in this embodiment includes: a slide 1, a chain support frame 2, and a chain 3. The chain support frame 2 cooperates with the slide (track) of the slide 1 and slides along the track under traction. The chain 3 hangs below the slide 1 and is connected to the chain support frame at the top. An oil tank 4 is provided above the slide 1, and a pipe joint 5 is provided at the bottom of the oil tank 4. The pipe joint 5 is connected to a dropper 6 with a valve 7 for dripping lubricating oil downward. An oil leakage hole 9 is provided on the slide 1, which is through and through, with a hole diameter of 6mm. The dropper and the oil leakage hole 9 correspond to the chain 3 in the upper and lower parts. The lubricating oil continuously dripped from the dropper 6 falls from the oil leakage hole 9 to the top of the chain 3 and flows downward along the chain, continuously lubricating the chain, keeping the chain in a lubricated state for a long time, effectively controlling the amount of chain wear, effectively increasing the service life of the chain, reducing the risk of chain breakage, and reducing equipment failure.
[0014] The above-mentioned PF line traction chain lubrication device has improved the lubrication spray method, solving the problem that the previous side oil and gas lubrication could only lubricate the surface of the chain, resulting in insufficient lubrication of the internal connection between the pin shaft and the middle ring, and adding a collection groove under the "C" hook to avoid oil pollution and realize the recovery of lubricating oil.
[0015] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
