Description

one

The invention relates to a lifting machinery industry, namely, to designs of bridge cranes with auxiliary devices, in particular with devices for servicing the zone of a blast furnace.

The aim of the invention is to simplify maintenance and improve working conditions.

FIG. 1 shows schematically a device, a plan view; in fig. 2 — coupling and unlocking mechanism, general view; in fig. 3 - the same plan view; in fig. D - section A-A in FIG. 3; in fig. 5 - device with uncoupled carts; 6, the same with coupled carts.

The bridge crane contains a cargo trolley 1, on which a pusher 2 is pivotally mounted, pivotally connected to drive 3, and an emphasis 4, an additional cart 5 on which a hook is pivotally fixed. 6, the lever 7 and the grip 8. The lever 7 and the grip 8 are pivotally connected with each other 9. The additional trolley 5 is also equipped with a pair of rollers 10 with a movable stop 11 connected to the spring 12 and supports 13. On the crane bridge, lanes 14 are installed An additional trolley is equipped with a mobile console 15.

Control of the device is carried out from the cab of the bridge foreman red.

The device works as follows.

In the rest position, the additional carriage 5 rests on the track with rollers 10 and supports 13. The gripper 8 is located in the grip of a scientific research institute with an emphasis 1A. At the approach of the cargo trolley 1 to the additional trolley 5, the stop 4 slides onto the hook 6, turning it until the hook 6 is fixed under its own weight with the stop D.

Simultaneously, the stop 4, interacting with the lever 7, turns it up to the stop (figure 4). In this case, the supports 13 release the track and the lever 7 provides additional support for the additional trolley 5. Turning the lever 7 by means of the hinged pin 9 rotates the grip 8 around the axis until it leaves the rail 20 with the support 14, the trolleys are ready for joint work.

Disengagement of the cargo and additional carts 1 and 5 with simultaneous fixation of the carriage 5 in the extreme position is as follows.

Coupled cargo and additional tracks 1 and 5 are brought to the extreme position as far as the stop of the roller of the additional trolley 5 at the stop 14. Include

30, the actuator 3, which rotates the pusher 2. The latter, interacting with the hook 6, disengages it from the stop 4, Retract the load trolley 1, the lever 7, freeing it from the fixation by the stop 4, rotates into its original weight position. The gripper 8, lowering, is fixed on the stop 14.
