Description

  The present invention relates to a coil car / floor plate coupling device that couples a coil car that transports a coil of a belt-like material and a floor plate that covers a pit in which the coil car moves, and disconnects the connection when the moved floor plate reaches a predetermined position.

  When rewinding and processing a coil wound with a band material such as a steel strip from a rewinding reel, the coil is transferred from the coil skid that primarily stores the coil to the rewinding reel, which is the point of contact with the crane or forklift that carries the coil. Coil cars are used for transport and mounting. In addition, a coil car is also used for taking out the coil from the take-up reel and transferring the coil to the coil skid after completion of the coil processing. And between the rails which a coil car moves, the pit is provided so that the coil raising / lowering apparatus arrange | positioned under the coil car can move. In order to prevent falling to the pit and to inspect or repair the reel and the coil skid, there is known a facility provided with a telescopic floor plate that can extend and retract to cover the pit.

  FIG. 5 (a) is a plan view showing a facility provided with a telescopic floor plate according to the prior art, and FIG. 5 (b) is a sectional view of the same, and includes a coil lifting device 5 that lifts and lowers the coil 3 and mounts it on the reel. The state where the coil car 1 has moved to the rewind reel 2 side is shown. In the coil car pit 12 between the coil skid 4 and the coil car 1, the floor plate 6b on the coil skid 4 side is pulled out of the storage space 8b on the coil skid 4 side by the movement of the coil car 1, and is covered with the floor plate 6b. Power is supplied to a driving device such as a motor of the coil car 1 by a flexible electric cable 1a.

  When the coil car 1 moves from the rewind reel 2 side to the coil skid 4 side, the floor plate 6b connected to the coil car 1 contracts between the coil skid 4 and the coil car 1 as the coil car 1 moves. On the other hand, the floor plate 6a whose end is connected to the coil car 1 is drawn out from the reel-side storage space 8a below the rewind reel 2, and covers the pit 12 between the rewind reel 2 and the coil car 1. . In this way, the entire pit 12 is covered with the floor plates 6a and 6b, thereby preventing the pit 12 from falling.

  As a prior art for preventing falling to the pit 12, for example, in Patent Document 1, the left and right guide rails arranged along the rails of the coil car and the left and right side ends are moved to the respective guide rails via the guide rollers. A safety device is disclosed comprising a net attached in a possible manner.
