Description

Technical Field

[0001] The present application belongs to the field of cold rolling production technology, and in particular relates to a cold rolling pickling line slip-on door rubber roller replacement device. Background Art

[0002] The main material of the pickling slip-on door rubber roller is a steel core polyurethane roller surface structure. During use, the pickling slip-on door rubber roller contacts the strip, causing wear of the polyurethane on its surface. Therefore, it is necessary to replace it according to the wear of the roller surface during each shutdown and maintenance.

[0003] In the prior art, the replacement of the rubber rollers of the pickling slip doors is usually carried out by manual operation and installed on the base. However, this method is relatively convenient for the installation of the rubber rollers on the first-layer slip doors with a minimum height of 1.3 meters from the ground. For the second-layer slip doors with a height of 2.3 meters from the ground and the third-layer highest one with a height of nearly 4 meters from the ground, it is dangerous to manually lift the rollers and use a crowbar to operate them in the process of dropping them into the installation groove, which may easily injure the hands. To replace the rollers on more than one layer, the workers need to stand on the equipment frame, wear safety belts, hold the equipment with one hand to prevent falling, hold the rollers with the other hand, stand on the equipment frame, use a crowbar, and drag the rubber rollers into the installation position. A series of operation steps require the cooperation of at least five people, which makes replacement difficult and involves great safety risks, and is very likely to cause safety accidents such as falls and bruises. Therefore, a device for replacing the rubber rollers of the slip doors of cold-rolled pickling lines is needed to improve replacement efficiency, reduce labor consumption, and reduce operational safety risks.

[0033] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0034] An embodiment of the present application provides a device for replacing the rubber rollers of the slip-on door of a cold-rolling and pickling milling line, which can reduce labor and improve replacement efficiency. The rubber rollers of the slip-on door of the cold-rolling and pickling milling line can be replaced by a single person.

[0035] First, see Figure 1 、 Figure 2, the embodiment of the present application provides a cold rolling and acid rolling line slipper door rubber roller replacement device, including: an installation tool 1, which is composed of a support end 2 and a suspension end 3 fixedly connected. The height of the installation work is usually 30-40 cm, and the worker can lift and install it alone. The support end 2 and the suspension end 3 form a bend structure, which is usually in a right angle shape to facilitate the extension of the suspension end 3. The bottom end of the installation tool 1 is provided with a groove 4, and the groove 4 is used to adapt to the size of the side guide wheel so that the groove 4 It can be embedded in the side guide wheel. In conventional technology, the cold rolling and acid rolling line is provided with a side guide wheel. The side guide wheel is an existing technology. The side guide wheel is used to guide the passage of the strip to avoid excessive wear caused by the inclination of the strip. The gear of the side guide wheel is approximately 10 cm thick, so that there is enough engagement space to enable the side guide wheel to engage with the groove 4, and the installation is more stable; the suspension structure, the suspension structure is fixedly installed on the free end of the suspension end 3, and the suspension structure is used to suspend the rubber roller of the cold rolling and acid rolling line loop door. The cold rolling mill line slip door rubber roller is installed and lifted to a convenient installation height through the suspension structure, and the steering of the device can be achieved through the cooperation of the groove 4 fixed at the bottom of the support end 2 and the side guide wheel, so that the horizontal position of the cold rolling mill line slip door rubber roller can be adjusted conveniently during the installation process, thereby realizing three-dimensional adjustment of the position of the cold rolling mill line slip door rubber roller, which is convenient for the staff to install. During use, it is only necessary to install the device on the side guide wheel and fix the cold rolling mill line slip door rubber roller on the suspension structure.
