Abstract
Description
Technical Field
[0001] The utility model relates to the application field of a cold rolling crane hot coil horizontal coil clamp, in particular to a grease storage tank of the cold rolling crane hot coil horizontal coil clamp. Background Art
[0002] The hot-rolled coil clamps used in the cold rolling mill's raw material warehouse are exposed to hazards such as water erosion and high coil temperatures, and the clamps operate frequently. After the clamp legs are lubricated with lubricating oil (#2 grease) for a week or less, the grease dissolves in the high temperature and is washed away by the water. This increases resistance to movement, exacerbates wear on the copper runners, and damages various layers of power-transmitting components. This leads to frequent failures, such as slippage of the torque limiter wear plate, increased wear on the friction plate, and sometimes even crushing of the friction plate. Excessive stress on the upper copper bushing and lower bearing securing the intermediate gear shaft causes damage, shortening their service life. Utility Model Content
[0003] The technical problem to be solved by the present invention is that there is no oil collection device at the end of the chute of the caliper leg. When the caliper leg is opened or closed, the grease on the surface of the caliper leg slider is scraped to the end of the chute. After the caliper leg is opened, the slider has no protective device. After the caliper leg is opened, the grease on the slider surface is dissolved by the high temperature environment and washed away by water. This results in increased resistance to movement of the caliper leg, increased wear of the copper chute, damage to different levels of components that transmit power, and frequent failure points. For example, the torque limiter wear plate slips, increased wear of the friction plate, and sometimes the friction plate is squeezed and broken. The upper copper bushing and lower bearing fixing the intermediate gear shaft are damaged due to excessive force, shortening their service life and seriously affecting the stable operation of the equipment.
[0004] In order to solve the above problems, the technical solution adopted by the present invention is as follows: The present invention is a grease storage tank for a cold rolling crane hot coil horizontal coil clamp, comprising an oil storage tank body, the oil storage tank body is clamped on the clamp leg slider, and a refueling nozzle is provided through the bottom wall of the oil storage tank body, and the height of the lubricating oil in the oil storage tank body needs to be slightly higher than the bottom of the clamp leg slider.
[0005] Furthermore, a scraper is tightly attached to the side wall of the oil storage tank body, a pressure plate is tightly attached to the scraper, and the lower part of the side wall of the oil storage tank body, the scraper and the pressure plate are fixed by bolts and nuts.
[0006] Furthermore, the scraper is made of rubber.
[0007] Furthermore, the pressure plate is made of a metal plate with a thickness of 15 mm to prevent the clamp from tilting and damaging the oil tank body.
[0008] Preferably, according to the size of the caliper leg slider, the size of the oil storage tank body is 150mm*100mm.
[0009] The beneficial effects achieved by the utility model using the above structure are as follows: After the cold-rolled plate and hot-rolled coil horizontal coil clamp adds a grease storage tank body at the end of the slide groove at the bottom of the clamp leg slider on the basis of the original design, the maintenance cycle of the clamp is extended, the service life of the equipment is extended, the labor intensity of the maintenance personnel is reduced, the efficient and stable operation of the crane equipment is ensured, the maintenance cost of the crane equipment is saved, and at the same time, it provides a guarantee for the improvement of the production capacity of the equipment and production units.

[0013] As the instruction manual Figures 1 and 2 As shown, the utility model is a grease storage tank for the cold rolling crane hot coil horizontal coil clamp.
[0014] When used specifically: it includes an oil storage tank body 1, which is engaged with the caliper leg slider. A refueling nozzle 2 is provided through the bottom wall of the oil storage tank body 1. The height of the lubricating oil in the oil storage tank body 1 needs to be slightly higher than the bottom of the caliper leg slider.
[0015] A scraper 3 is tightly attached to the side wall of the oil storage tank body 1 , and a pressure plate 4 is tightly attached to the scraper 3 . The lower part of the side wall of the oil storage tank body 1 , the scraper 3 and the pressure plate 4 are fixed by bolts and nuts.
[0016] The scraper 3 is made of rubber. The pressing plate 4 is made of a metal plate with a thickness of 15 mm to prevent the clamp from tilting and damaging the oil tank body 1.
[0017] According to the size of the caliper leg slider, the size of the oil storage tank body 1 is 150mm*100mm.
[0018] During specific use: add a 150mm long and 100mm wide grease storage tank body 1 at the end of the bottom slide of the clamp leg slider, add grease in the oil tank to exceed the height of the slider, and add a 15mm thick pressure plate 4 on the edge of the oil storage tank body 1 to prevent the clamp from tilting and damaging the oil storage tank body 1, and the clamp leg slider from invading the oil tank grease to ensure that there is enough grease on the slider surface. The oil storage tank body 1 is filled with oil once, which ensures that there is still lubricating oil on the slider surface after the clamp leg runs for one month, which greatly improves the use and operation of the clamp.
[0019] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
