The invention discloses a crane which is composed of a main trolley, a subsidiary trolley and a three-beam four-track crane span structure. The main trolley is provided with a hoisting mechanism, wherein the drum axis of the hoisting mechanism is parallel to the track direction of the crane span structure, a sling is arranged below the hoisting mechanism, and a tilting gear is arranged on the sling. The subsidiary trolley is provided with a hoisting mechanism and a subsidiary hoisting mechanism, wherein the drum axis of the hoisting mechanism and the drum axis of the subsidiary hoisting mechanism are perpendicular to the track direction of the crane span structure, a sling is arranged below the hoisting mechanism, a clamp is arranged on the sling, another sling is arranged below the subsidiary hoisting mechanism, and steel ingots or forge pieces are forged and transported in the mode that different chains are arranged on the slings to be matched with the tilting gear or the clamp. The slings arranged on the three hoisting mechanisms can rotate 360 degrees respectively. The crane has both the function of a forge crane and the function of a transport crane, thereby being capable of reducing investment of production cost and saving the space in a plant at the same time.

The specific embodiment

Below in conjunction with the specific embodiment, the present invention is elaborated.

Present embodiment adopts double trolley three beam four rail structures, as shown in Figure 1, main carriage 1, secondary dolly 21, three beam four rail crane span structures 3, consists of.

The main carriage 1(that main carriage adopts existing forging crane as shown in Figure 2).On main carriage 1, be provided with lifting mechanism 17, its spool axis is parallel with the track alignment of crane span structure 3.Supporting suspender 7 and tilting gear 8 below main carriage 1, this is identical with the configuration of existing forging crane, as shown in Figure 4.

On secondary dolly 21, be provided with lifting mechanism 18 and auxiliary hoisting mechanism 22, the spool axis of lifting mechanism 18 and auxiliary hoisting mechanism 22 is vertical with the track alignment of crane span structure 3.The travelling bogie 2(that secondary dolly can adopt existing transport crane as shown in Figure 3), but require auxiliary hoisting mechanism 19 on travelling bogie 2 be able to meet or higher than the secondary dolly 6(of existing transport crane as shown in Figure 2) all requirements of lifting mechanism, the technical performance parameter of the auxiliary hoisting mechanism 22 of secondary dolly 21 of the present invention will be got by the high technical parameter of requirement in the lifting mechanism of secondary dolly 6 of existing forging crane and the auxiliary hoisting mechanism of existing transport crane 19.The secondary lifting mechanism 18 of dolly 21 and the travelling bogie 2(of existing transport crane are as shown in Figure 3) lifting mechanism 18 identical, supporting suspender 9 and clamp 10 below it, as shown in Figure 5.The configuration suspender 11 identical with the hanger structure of existing forging crane below auxiliary hoisting mechanism 22, but its hoisting capacity is also by larger getting, by hang different chains on suspender 11, coordinate tilting gear 8 or clamp 10 to complete forging and the transportation function of steel ingot 20 or forging 16, be that auxiliary hoisting mechanism 22 can coordinate the lifting mechanism 17 of
