When the driving mechanism 3 is started at this time, torque is input to the transmission chain wheel 41 through the output shaft, and the torque can not be transmitted any more because the clutch coupling 15 is disengaged, so that the torque of the driving mechanism 3 is transmitted to the emergency chain wheel 42 in transmission connection with the actuating mechanism 1 through the transmission chain 43, and the rotating side of the emergency chain wheel 42 drives the actuating mechanism 1 to rotate to complete the first working condition.
Rope changing working condition:
fig. 6 is a schematic diagram illustrating a main reel renewing process according to an exemplary embodiment of the present invention, as shown in fig. 6, when a quayside crane needs to be renewed, a prepared new reel 16 wound with a new wire rope is placed in a machine room of the quayside crane, a head end of the new wire rope is wound on the main reel 11, then the clutch coupling 15 is closed, the driving mechanism 3 is started, an output torque of the driving mechanism 3 is transmitted to the main reel 11 through the clutch coupling 15, the main renewing reel 11 rotates to wind the new wire rope on itself, after all the new wire ropes are wound, the first locking portion 51 is released by rotating the locking hand wheel 58, since the main reel 11 is clamped and fixed with the conical surface of the supporting cone 61 through the locking cone shaft 53, after the first locking portion 51 is released, the main reel 11 can be taken down, and the second locking portion 52 is released by the same method to detach the auxiliary reel 12, the main drum 11 on which a new wire rope is wound is replaced with the sub-drum 12 and reinstalled, and at this time, the sub-drum 12 is gripped by the first locking portion 51 and the main drum 11 is gripped by the second locking portion 52. At this time, the main drum 11 is in the clamping position of the sub drum 12, the sub drum 12 is in the clamping position of the main drum 11, a new wire rope is wound on the main drum 11, and the sub drum 12 is an empty drum.
Fig. 7 is a schematic diagram illustrating a principle of performing a reel-to-reel rope changing process according to another exemplary embodiment of the present invention, as shown in fig. 7, a rope changing operation is performed, one end of an old steel wire rope wound on an execution reel 13 of an execution mechanism 1 is connected to an auxiliary reel 12 and fixed, and one end of a new steel wire rope on a main reel 11 is connected to the other end of the old steel wire rope on the execution reel 13, so that the new and old steel wire ropes are connected together to form a series connection, when a driving mechanism 3 drives the auxiliary reel 12 to rotate, the old steel wire rope is wound on the auxiliary reel 12, and the new steel wire rope on the main reel 11 is wound on the execution reel 13 by traction until the new rope is completely wound on the execution reel 13, and the driving mechanism 3 is manually stopped to finish the rope changing operation. After finishing the rope changing action, the new and old ropes are separated, the driving mechanism 3 can be started again to rotate reversely so as to drive the auxiliary winding drum 12 to rotate reversely, the old steel wire rope is withdrawn from the auxiliary winding drum, the step of manually taking the old rope off the auxiliary winding drum 12 is omitted, and the working efficiency is improved.
Another implementation situation exists in the rope changing working condition:
the new reel 16 wound with the new wire rope reel can be directly exchanged with the auxiliary reel 12, the main reel 11 is still an empty reel, and the auxiliary reel 12 is positioned at the new reel 16 with the new wire rope reel, so that the steps of winding the new wire rope and exchanging the main reel 11 and the auxiliary reel 12 are omitted, and the working efficiency of rope exchange is further improved.
An embodiment of the present invention further provides a shore bridge, including: a shore bridge body; and a shore bridge propulsion unit as described in any one of the above; wherein, bank bridge drive arrangement sets up on the bank bridge body.
Through using bank bridge drive arrangement on the bank bridge, can more convenient and fast change the rope for the bank bridge, also can provide emergent drive power for the bank bridge simultaneously, make the bank bridge also can the various operating modes of safe handling under emergency, promote the security when improving the efficiency for bank bridge work.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and the like that are within the spirit and principle of the present invention are included in the present invention.
