Embodiment 1

[0039] Embodiment 1 of the present invention provides a transfer case, see figure 1 , the transfer case includes a case body 2, a transfer shaft 3, a transmission member, a shifting device and at least three output shafts.

[0040] Wherein, the transfer shaft 3 is used as the power output and output shaft of the transfer case, and the transfer shaft 3 is arranged in the case body 2, specifically, the transfer shaft 3 is arranged in the case body 2 through a bearing.

[0041] In this embodiment, the output shaft is also arranged in the box body 2, specifically, it can be arranged in the box body 2 through a bearing or a bearing and a bearing seat, and the number of output shafts is at least three, preferably three.

[0042] The transmission part is arranged on the transfer shaft 3, and the transmission part is used to drive the output shaft to rotate, and the transmission part can idle relative to the transfer shaft 3, and the transmission part can still be arranged on the tran...

Embodiment 2

[0070] Embodiment 2 of the present invention provides a crane, refer to Figure 7 with Figure 8 , the crane includes a motor 1, a reducer 13 and a first transmission mechanism for driving the crane to move, a slewing bearing 21 for driving the crane to rotate, a second transmission mechanism for lifting the crane, a vehicle frame, an elevator 34, and a balance beam 20 and the aforementioned transfer case.

[0071] Wherein, the output shaft of the motor 1 is in transmission connection with the transfer shaft 3 of the transfer case, and the motor 1 provides power to drive the transfer shaft 3 to rotate.

[0072] Vehicle frame comprises driving vehicle frame 30 and driven vehicle frame 35, and each crane comprises driving vehicle frame 30 and driven vehicle frame 35, and driving vehicle frame 30 and driven vehicle frame 35 are all connected with balance beam 20 by slewing bearing 21, and elevator 34 Then it is connected with the middle part of the balance beam 20 , and a tie r...

Abstract

The invention provides a transfer case and a crane, and belongs to the technical field of cranes. The transfer case comprises a case body, a transfer shaft, a gearshift device, at least three output shafts and at least three transmission parts, the transfer shaft and at least three output shafts are rotatably arranged on the case body, at least three transmission parts are used for driving the output shafts to rotate, the transmission parts can idle relative to the transfer shaft, and the transmission parts correspond to the output shafts one-to-one; and the gearshift device comprises a driving mechanism and at least three poking forks, the poking forks are slidably arranged on the transfer shaft in a sleeving mode and rotate simultaneously relative to the transfer shaft, the poking forks correspond to the transmission parts one-to-one, the driving mechanism is used for driving the poking forks to mesh with or separate from the transmission parts. The transfer case is reasonable in structure and simple in operation, and rotation of the multiple output shafts at any time can be achieved. The crane has a simple control system, and can walk, lift and slew conveniently.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a transfer case and a crane. Background technique [0002] Along with global economic integration, logistics is like the blood vessel that transports blood in the human body, carrying the lifeblood of global economic development. With the acceleration of economic development, port logistics has put forward higher requirements for the efficiency of container loading and unloading. [0003] At present, most of the on-site container handling equipment in large ports are tire-type container gantry cranes. This equipment has the ability to move freely, and has the advantage of lower requirements for yard pavement, and is deeply loved by port customers. In particular, large-scale professional container ports have maintained a relatively high number of tire-type container gantry cranes. [0004] The reason why rubber-tyred container gantry cranes are popular with port customers is that ...
