Description

Convenient looper roll changing device

technical field

The utility model relates to the metallurgical industry, in particular to a convenient looper roller changing device.

Background technique

The high-speed cold-rolling unit provides enough strip steel storage capacity to ensure that the unit can run continuously when the switchover of uncoiling causes the entrance section to pause. Therefore, the looper comes into being, which often includes a looper tower structure, two vertical guide rails, a looper car, and a counterweight balancing and stabilization system for the looper car. The looper tower structure consists of the following: a steel structure to support the looper track, a tower top platform to support the cable pulley, and a cable locking device located on three sides of the looper tower and leading to the top. aisle. Two vertical guide rails are installed on the looper tower steel structure, and four static pulleys are used to steer the winch cable and are installed on the tower top platform. A hoisting cable anchor point is installed on the tower top platform and equipped with buffers and overload detection devices. A counterweight balancing and stabilizing system consisting of the following: a set of counterweights made of steel plate, two connecting cables connecting the looper and the counterweight, four connecting cables installed on the top platform of the tower for steering Static pulleys, 2 manual locks for looper maintenance, limit switches, a safety stop. A looper consists of the following components: a welded frame of the looper, 20 steering rollers (passive rollers), 2 static pulleys and guide wheels for steering the hoisting cables.

However, when changing the looper roll, it is necessary to design a set of roll changing device on the looper tower and fix it on the looper. In this way, on the one hand, the investment in equipment is increased, on the other hand, this set of equipment can only be used in the unit, which has certain limitations. In order to quickly and effectively solve the imminent problem of changing looper rolls, a convenient looper roll changing device is urgently needed.

Utility model content

The purpose of the utility model is to provide a convenient looper roller changing device, which can move conveniently and quickly to replace the required looper rollers, reduce equipment investment, save downtime, reduce labor intensity of workers, and improve production efficiency.

The technical scheme of the utility model is: a convenient looper roller changing device, which includes: a main frame with a beam, a driving motor moving along the beam, a manual electric hoist arranged under the driving motor, and a manual electric hoist suspended on the The hanger, and the looper roller that is replaceably suspended on the hanger.

Preferably, the main frame includes a plurality of pillars perpendicular to and supported by the crossbeam, rollers at the ends of the corresponding pillars, a movable hinge seat on one side of a pillar, and a switch box fixed on a pillar.

Preferably, it further includes cables connected to both the drive motor and the switch box.

Preferably, it further includes a first counterweight disposed above the beam, and a second counterweight located below the beam and above the rollers.

Preferably, the beam is provided with a plurality of limit blocks cooperating with the switch box.

Preferably, the movable hinge base and the rollers are metal processing parts.

The utility model advantage is:

When replacing the looper roller, the device can be easily and quickly moved to the unit for replacement, which saves downtime, reduces labor intensity of workers, and improves production efficiency. In addition, the device can also be used in different production units, thereby avoiding waste of resources and having stronger market competitiveness.
