Abstract

The utility model discloses a crane which is used in a foundry workshop and used for solving the problem that the prior foundry crane can not tip over a hot metal tank in the vertical direction of a bridge frame. The structure is as follows: the axial directions of main and auxiliary hook winch drums of the crane are arranged to be consistent with the direction of a main beam of the bridge frame; the distance between main and auxiliary hooks is equal to the rotation radius of the hot metal tank while being dipped over; the distance between the main hook and the inside of the main beam of the bridge frame and the distance between the auxiliary hook and the inside of the main beam of the bridge frame are arranged to ensure that the hot metal tank can not be touched with the main beam when the hot metal tank is dipped over. As the hot metal tank can be dipped over along the vertical direction of the main beam of the bridge frame, the difficult problem of adding and receiving hot metal when a hot metal transport line vertically crosses a hot-metal mixer plant is solved, thereby meeting the process requirements of a plurality of special places which are limited by the space conditions.

Description

The hoisting crane that foundry shop uses

Technical field

The utility model relates to hoisting crane, especially the hoisting crane used of foundry shop.

Background technology

At present, the crane structure that foundry shop uses is seen Fig. 4, and all the crane span structure of being made up of girder, running trolley, main hook (claiming gantry hook again), auxiliary hook, major-minor hook reel are formed.As can be seen from Figure 4, its major and minor hook reel 5 with 6 axially vertical with crane span structure girder arranged direction.When with the crane for hoisting hot-metal bottle of this structure, hot-metal bottle can only be tumbled along the crane span structure length direction, and can't tumble along the crane span structure vertical direction.When fascinating when direction and molten iron lane of traffic plumbness of mixed iron blast, the ladle carne of this version just can not satisfy the operation requirements that adds, connects molten iron.

Summary of the invention

Can not be in order to overcome existing ladle carne along the tumble deficiency of hot-metal bottle of crane span structure vertical direction, the utility model provides a kind of major-minor hook arranged direction the ladle carne vertical with crane span structure, can realize that hot-metal bottle tumbles along the crane span structure vertical direction, in order to satisfy specific technological requirement.

The technical scheme that its technical matters that solves the utility model adopts is, comprises original crane bridge, running trolley, main hook, auxiliary hook, major-minor hook reel, it is characterized in that major-minor hook reel axially consistent with crane span structure girder direction layout; Radius of rotation when the distance between main hook and the auxiliary hook equals hot-metal bottle tipping; When should guaranteeing hot-metal bottle tipping, the distance of the distance of main hook and crane span structure girder inboard and auxiliary hook and crane span structure girder inboard do not collide with girder.

During use, utilize main hook on the crane span structure to hang the gudgeon of hot-metal bottle, auxiliary hook is hung the hanger of tumbling at hot-metal bottle, just can realize the action of tumbling of hot-metal bottle by the dipping and heaving of main hook and auxiliary hook.

The beneficial effects of the utility model are: because hot-metal bottle can be tumbled along crane span structure girder vertical direction, solved the difficult problem that adds, connects molten iron when the molten iron lane of traffic is vertically passed through the mixed iron blast factory building, satisfied some and be subjected to the technological requirement in special places such as site condition restriction.

Fig. 2 is the birds-eye view of the utility model embodiment;

Fig. 3 is the left view of the utility model embodiment;

Fig. 4 is the birds-eye view of the hoisting crane used of existing foundry shop.

Among the figure: 1-crane span structure, 2-dolly, 3-main hook, 4-auxiliary hook, 5-main hook winch drum, 6-auxiliary hook reel.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model comprises crane span structure 1, running trolley 2, main hook 3, auxiliary hook 4, main hook winch drum 5, auxiliary hook reel 6, running trolley 2 is installed on the track above the crane span structure 1, realizes that by the dipping and heaving of major and minor hook and the motion all around of large and small car hot-metal bottle adds, connects the action of molten iron to mixed iron blast.Wherein major and minor hook reel 5 is arranged consistent with 6 axial and crane span structure 1 girder direction; Between main hook 3 and the auxiliary hook 4 equal hot-metal bottle tipping apart from a the time radius of rotation r; The distance b of main hook 3 and crane span structure 1 girder inboard ₁And the distance b of auxiliary hook 4 and crane span structure 1 beam inboard ₂Do not collide in the time of should guaranteeing hot-metal bottle tipping with girder.

Claims (1)

1, the hoisting crane used of a kind of foundry shop comprises crane bridge, running trolley, main hook, auxiliary hook, major-minor hook reel, it is characterized in that major and minor hook reel axially consistent with crane span structure girder direction layout; Radius of rotation when the distance between main hook and the auxiliary hook equals hot-metal bottle tipping; When should guaranteeing hot-metal bottle tipping, the distance of the distance of main hook and crane span structure girder inboard and auxiliary hook and crane span structure girder inboard do not collide with girder.
