Description

Replacing tool of fixed block type bending and channeling device of hot continuous rolling finishing mill

Technical Field

The utility model relates to a change instrument of key equipment on hot continuous rolling production line finishing mill group belongs to machinery.

Background

At present, a fixed block type bending and channeling device of a hot continuous rolling finishing mill group mainly comprises three replacing methods: the first method is that a crown block and a chain block or a hand plate block are used for moving a bending and fleeing device to the installation position of a window of a housing of a rolling mill; the second is to install the bending and fleeing device in place by utilizing an automobile crane and a chain block or a hand plate block; and the third is that the balance beam of the upper supporting roll of the rolling mill is used as a track, and the suspension frame with the roller moves in the rolling mill and is matched with a chain block or a chain block to install the bending and fleeing device in place.

The first replacement method comprises the following working principle that firstly, a bending and fleeing device is hung outside a window of a rolling mill by using an overhead travelling crane, then, at least three chain blocks or chain blocks are used for hanging the bending and fleeing device and keeping the balance of the bending and fleeing device, the hanging points at the upper parts of the chain blocks are repeatedly replaced, the bending and fleeing device is slowly moved to the mounting position in the rolling mill by retracting and releasing the lengths of three chain blocks, and the process is opposite when the bending and fleeing device is detached, and the first replacement method has the defects that: 1. the occupied crown block can influence the hoisting of other equipment maintenance, and 2, because the periphery of the rolling mill is provided with a railing, a platform and the like, the bent channeling device is lifted by the crown block and is close to the rolling mill, and has a certain distance from a window of the rolling mill, so that the bent channeling device can be installed in place only by repeatedly replacing the position of a hoist in the follow-up process, which wastes time and labor; the operating principle of the second replacement mode is that a bent fleeing device is hung near a replacement position by utilizing a cantilever of a truck crane, so that the time of repeatedly overturning and bending the bent fleeing device by a chain block or a chain block is reduced, and the defect is that: 1. the mobile cranes are large in size, the overhaul space and the hoisting channel of other equipment in front of the finishing mill are occupied, 2, one mobile crane can only replace one bending and fleeing device at one time, the finishing mill group is generally seven rolling mills, the space in front of the finishing mill group is limited, more than two mobile cranes cannot be parked at the same time, the bending and fleeing device is long in dismounting and mounting time, and 3, the cost of the mobile cranes is high; the theory of operation of third kind of change mode is for placing the frame of taking the gyro wheel on upper supporting roller compensating beam at first, and chain block or chain block are hung to the below of frame, also will bend through adjusting the fixed position on chain block or chain block upper portion and scurry the device installation and target in place, and its shortcoming is: 1. the upper supporting roll can be moved out of the rolling mill to expose the balance beam only by executing a roll changing procedure of the supporting roll, the preparation time is long, and 2, the bending and crossing device can be installed in place only by repeatedly changing the position of a hoist in the follow-up process, so that time and labor are wasted. In a word, the three methods for replacing the bending and fleeing device have extremely low working efficiency, and meanwhile, the bending and fleeing device is higher away from the ground, so that the safety risk exists.
