Description
Technical Field
The utility model relates to a backing roll dismouting machine reducing device belongs to metallurgical industry slab band production facility technical field.
Background
The plate strip production line is generally matched with a special supporting roll dismounting machine for dismounting the supporting roll and the bearing seat. The supporting roller disassembling and assembling machine is provided with an intermediate base, four rotating carrier rollers are mounted on the base and used for supporting rollers, two of the rotating carrier rollers are driving carrier rollers, and the other two rotating carrier rollers are driven carrier rollers. The driving carrier roller is driven by a motor to rotate and drives the roller to rotate by using friction force. Lifting tables driven by hydraulic cylinders are arranged on two sides of the disassembling and assembling machine, so that the roller and the bearing block are centered in the vertical direction; the lifting platform can also move along the axial direction of the roller, and finally the disassembly and assembly of the supporting roller and the bearing seat thereof are completed.
At present, the diameter of a roller which can be disassembled and assembled by a supporting roller disassembling and assembling machine matched with a plate strip production line is generally 850-1600 mm. When a roller with a smaller diameter needs to be disassembled and assembled, for example, a flattening roll-splitting working roller matched with a plate strip production line has a diameter of 550mm, and the driving carrier roller and the driven carrier roller have too large space, so that the roller with the smaller diameter cannot be supported and disassembled. When the small-diameter roller needs to be disassembled and assembled, the disassembly and assembly efficiency is low due to manual disassembly and assembly; or a small-diameter dismounting machine is reordered, so that the investment is high. Therefore, a suitable device is developed to expand the working range of the supporting roller dismounting machine, so that the bearing seat of the small-diameter roller can be dismounted quickly and conveniently.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a backing roll dismouting machine reducing device can support the major diameter backing roll, can support the minor diameter roll again, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
the utility model provides a backing roll dismouting machine reducing device, contains middle bearing roller, rocking arm, quick detach round pin, support, dismouting machine base, dismouting machine initiative bearing roller and the driven bearing roller of dismouting machine, and dismouting machine initiative bearing roller and the driven bearing roller of dismouting machine set up respectively on the dismouting machine base, and the distance between dismouting machine initiative bearing roller and the driven bearing roller of dismouting machine and the great backing roll phase-match of diameter, the one end of rocking arm is passed through the quick detach round pin and is rotated the connection on the support, the support is fixed on the dismouting machine base between dismouting machine initiative bearing roller and the driven bearing roller of dismouting machine, and the other end and the middle bearing roller of rocking arm rotate to be connected, middle bearing roller presses on the driven bearing roller of dismouting machine.
The middle carrier roller is positioned between the driving carrier roller of the disassembling and assembling machine and the driven carrier roller of the disassembling and assembling machine.
The middle carrier roller is pressed obliquely above the driven carrier roller of the disassembling and assembling machine.
The distance between the middle carrier roller and the driving carrier roller of the disassembling and assembling machine is matched with the roller with smaller diameter.
When the small-diameter roller and the bearing seat thereof need to be disassembled and assembled, the small-diameter roller is placed between the middle carrier roller and the driving carrier roller of the disassembling and assembling machine; when the large-diameter supporting roller and the bearing seat thereof need to be disassembled and assembled, the quick-disassembling pin is disassembled, the rocker arm and the middle carrier roller are moved away from the space between the driving carrier roller of the disassembling and assembling machine and the driven carrier roller of the disassembling and assembling machine, and the large-diameter supporting roller is placed between the driving carrier roller of the disassembling and assembling machine and the driven carrier roller of the disassembling and assembling machine.
The utility model has the advantages that: the large-diameter supporting roll and the bearing seat thereof can be disassembled and assembled, the small-diameter roll and the bearing seat thereof can be disassembled and assembled, the working range of the supporting roll disassembling and assembling machine is expanded, and the large-diameter supporting roll disassembling and assembling machine has the advantages of simple structure, quickness in disassembling and assembling, low investment and the like.
