Abstract
Provided is a device for demounting a backing bearing of a rolling mill. The two sides between an upper bearing baffle (3) and a lower bearing baffle (3) are connected with a connecting rod (5) respectively, a hydraulic cylinder (1) penetrates through the center of the upper bearing baffle (3), cylinder body fixing bolts (2) are arranged on the upper bearing baffle (3) on the left side and the right side of the hydraulic cylinder (1), then the hydraulic cylinder (1) is fixed on the upper bearing baffle (3), and a shaft outlet (4) is formed in the center of the lower bearing baffle (3). When the device works, a backing bearing set (8) is flatwise placed on the ground, the head (6) of a hydraulic rod of the hydraulic cylinder (1) is directed at a mandrel (7) at the center of the backing bearing set (8), the hydraulic rod stretches to push the mandrel (7) at the center of the backing bearing set (8) out, a cable wire penetrates through a shaft hole in the center of the backing bearing set (8), and then the backing bearing set (8) can be conveniently demounted. The device for demounting the backing bearing of the rolling mill is small in labor intensity for demounting the backing bearing set, short in working time, and high in working efficiency.
Description
Technical field
The invention relates to the provision for disengagement of a kind of milling train back lining bearing.
Background technology
The back lining bearing weight of strip mill is heavier, and the artificial unloading hangs out bearing after need whole group of back lining bearing being erected by driving more one by one, and labour intensity is large, and the working time is many, and operating efficiency is low.
Summary of the invention
The technical problem that the invention will solve provides that a kind of labour intensity is little, the working time is few, the milling train back lining bearing provision for disengagement of high efficiency.
The concrete technical scheme of the invention is: the provision for disengagement of milling train back lining bearing, comprise hydraulic cylinder, cylinder body gim peg, bearing baffle, connecting rod, respectively be connected with a connecting rod on two limits between two bearing baffles up and down, hydraulic cylinder is equipped with at the center of passing the top bearing baffle, a cylinder body gim peg respectively is housed on the top bearing baffle on two limits about hydraulic cylinder hydraulic cylinder is fixed on the bearing baffle of top, there is individual shaft outlet hole at bearing baffle center, below.During work, to lie in ground under the back lining bearing group, the hydraulic stem head of hydraulic cylinder is aimed at the mandrel of back lining bearing group switching centre, when hydraulic stem stretches out the mandrel of back lining bearing group switching centre is released, pass the axis hole of back lining bearing group switching centre with cable wire, just can dismantle easily lower backing bearing group.The lower backing bearing group labour intensity of the invention dismounting is little, the working time is few, high efficiency.
Description of drawings
Fig. 1: the invention master TV structure schematic diagram.
The specific embodiment
A kind of embodiment of the invention is described by reference to the accompanying drawings.
The provision for disengagement of a kind of milling train back lining bearing, comprise hydraulic cylinder 1, cylinder body gim peg 2, bearing baffle 3, connecting rod 5, respectively be connected with a connecting rod 5 on two limits between two bearing baffles 3 up and down, hydraulic cylinder 1 is equipped with at the center of passing top bearing baffle 3, a cylinder body gim peg 2 respectively is housed on the top bearing baffle 3 on hydraulic cylinder about 1 two limits hydraulic cylinder 1 is fixed on the bearing baffle 3 of top, there is individual shaft outlet hole 4 at bearing baffle 3 centers in below.During work, the back lining bearing group is lain in ground 8 times, the hydraulic stem head 6 of hydraulic cylinder 1 is aimed at the mandrel 7 at back lining bearing group 8 centers, when hydraulic stem stretches out the mandrel 7 at back lining bearing group 8 centers is released, pass the axis hole at back lining bearing group 8 centers with cable wire, just can dismantle easily lower backing bearing group 8.The lower backing bearing group labour intensity of the invention dismounting is little, the working time is few, high efficiency.
