Offshore platform cranes for lifting cargoes and personnel are generally arranged on offshore platforms such as offshore oil drilling platforms, offshore wind turbine platforms and the like. In order to ensure the safety of the lifted personnel when the offshore platform crane is used for lifting the personnel, the embodiment of the utility model provides a driving device of the offshore platform crane.
Fig. 1 is a schematic structural view of a driving device of an offshore platform crane according to an embodiment of the present utility model, and fig. 2 is a cross-sectional view of the driving device of the offshore platform crane according to the embodiment of the present utility model. Referring to fig. 1 and 2, a driving device for an offshore platform crane according to an embodiment of the present utility model includes: the drive assembly 100, the spool 200, the first sensing element 110 and a first brake (not shown).
The driving assembly 100 is in transmission connection with the winding drum 200, the driving assembly 100 is used for driving the winding drum 200 to rotate, the winding drum 200 is used for winding a steel wire rope, one end of the steel wire rope is wound on the winding drum 200, and the other end of the steel wire rope is connected with a hoisted person.
The driving assembly 100 is provided with a first detecting element 110 for detecting a winding speed of the wire rope and a length of the wire rope to be wound, and a first brake for braking the driving assembly 100.
Specifically, the drive assembly 100 may include a motor, a drive shaft, and a control system capable of controlling the first brake to brake the motor. The motor is in driving connection with the drum 200 through a driving shaft, the first detecting element 110 may detect the rotational speed of the motor, and send a detection signal to the control system, which can calculate the winding speed of the wire rope and the length of the wound wire rope, thereby determining the lifting speed and position of the lifted person. The length of the wound wire rope when the personnel is lifted to the offshore platform can be stored in the memory of the control system, and the threshold value of the lifting speed of the personnel can also be stored, so that the control system controls the first brake to brake the motor according to the detection signal transmitted by the first detection element 110 when the personnel arrives at the offshore platform or the winding speed of the wire rope exceeds the threshold value, thereby ensuring the safety of the personnel climb a hill at the offshore platform and improving the efficiency of the personnel logging on the offshore platform.
The first brake may be an electromagnetic brake, and the first detecting element 110 may be a rotary encoder.
As shown in fig. 1 and 2, in some examples of the embodiment of the present utility model, the driving apparatus may further include a second detecting element 300 and a second brake 400.
For offshore platform cranes, the working scenario is wet, in which case the risk of failure of the first detection element 110 or the first brake may occur. In this case, the driving device of the offshore platform hoist may be further provided with a second sensing element 300 and a second brake 400. The second detecting element 300 and the second brake 400 are disposed at an end of the drum 200 facing away from the driving assembly, the second detecting element 300 is used for detecting a winding speed of the wire rope and a length of the wire rope to be wound, and the second brake 400 is used for braking the drum 200. In this way, the second detecting element 300 can detect the winding speed of the wire rope and the length of the wire rope to be wound when the first detecting element 110 fails, and the second brake 400 can brake the spool 200 when the first brake fails, thereby avoiding the occurrence of a risk due to the failure of the first detecting element 110 or the first brake.
The second brake may be an electromagnetic brake, and the second detecting element 300 may be a rotary encoder.
As shown in fig. 2, in some examples of the embodiment of the present utility model, the driving device may further include a decelerator 500, where the decelerator 500 is disposed at an end of the drum 200 facing away from the driving assembly 100, and is disposed coaxially with the drum 200, the driving assembly 100, the second brake 400, and the second detection element 300, and the decelerator 500 is used to decelerate the drum 200, so that the time required for braking the driving device can be reduced.
As shown in fig. 1, in some examples of embodiments of the present utility model, the driving apparatus may further include a rope-loosening detecting element 210.
Specifically, the rope-loosening detecting element 210 is disposed on the spool 200, for example, may be disposed on the outer side in the circumferential direction of the spool 200, and may be disposed at a distance from the circumferential side wall of the spool 200. The rope loosening detection element 210 is used for detecting the rope loosening state of the steel wire rope wound on the winding drum 200, and when the steel wire rope wound on the winding drum 200 is loosened, the rope loosening detection element 210 can be triggered to act, and the rope loosening detection element 210 acts to send a signal to the control system, so that the driving device is controlled to stop, and the danger caused by rope loosening is avoided.
It should be noted that, the technical solutions in the embodiments of the present utility model may be combined with each other, but the basis of the combination is based on the fact that those skilled in the art can realize the combination; when the combination of the technical solutions contradicts or cannot be realized, it should be considered that the combination of the technical solutions does not exist, i.e. does not fall within the scope of protection of the present utility model.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
