Embodiment 1

[0037] Embodiment 1. The automatic power-taking mechanism used for gantry cranes in this embodiment includes a connection mechanism. The connection mechanism is connected to a plug frame 1 through a detachable coupling mechanism. The plug frame 1 is matched with a socket frame 2, and the plug frame 1 It can be fixed with the socket frame 2 by a locking mechanism.

[0038] The plug frame 1 includes a plug frame 11 , a coupling assembly 12 for connecting a docking mechanism, a power-taking electrode 13 fixed in the plug frame 11 , and a power cable connected to the power-taking electrode 13 .

[0039] The docking mechanism includes front and rear telescopic modules, up and down moving modules and a detachable coupling assembly 12 connected with the plug frame 1 . Front and rear telescopic modules, moving the modules up and down can make the connecting mechanism control the flexible movement of the plug frame 1. The connection mechanism can be various mechanical arms or mechanic...

Embodiment 2

[0049] Embodiment 2, this embodiment has made further improvement on the basis of embodiment 1.

[0050] In the above step 1, the gantry crane carrying the plug frame 1 is driven to the side of the socket frame 2 with its own power supply. The connecting part of the docking mechanism is connected with the coupling assembly 12 on the plug frame 1 . A cable reel is provided on the gantry crane, and after the connecting mechanism is aligned with the socket frame 2, it pauses first, and then the cable reel works to loosen the power cables connected by the connecting mechanism.

[0051] In this embodiment, the positioning can be done by means of ground marking lines or GPS positioning systems or radio frequency positioning systems or by means of the reflective plate installed on the socket frame 2 and the photoelectric light on the gantry crane or by means of the upper limit stopper installed on the socket frame 2 and the installation After the stroke switch on the gantry crane re...

Embodiment 3

[0060] Embodiment 3, this embodiment has made further improvements to Embodiment 1 or Embodiment 2.

[0061] In this embodiment, in view of the large inertia of the gantry crane, it is difficult for the connecting mechanism to achieve the millimeter-level precise positioning required by the locking mechanism in one step, regardless of whether it relies on GPS, radio frequency positioning system, marking line, or travel switch photoelectric switch when stopping. This is especially true for rubber-tyred gantry cranes and has therefore been further optimized.

[0062] In this embodiment, the ground marking line or the GPS positioning system or the radio frequency positioning system or the photoelectric switching on the reflector installed on the socket frame 2 and the gantry crane or the upper limit stopper installed on the socket frame 2 and the gantry crane are installed. Itinerary consecration has achieved preliminary positioning at the decimeter level. After the preliminary ...

Abstract

The invention discloses an automatic electricity-getting mechanism which is accurately and automatically connected with and reliably fixed to a socket frame through a plug frame and used for a gantry crane and an automatic electricity-getting method. The automatic electricity-getting mechanism for the gantry crane comprises a connecting mechanism, wherein the connecting mechanism is connected with the plug frame through a coupling mechanism which can be separated; the plug frame is mated with the socket frame; and the plug frame and the socket frame can be fixed together through a locking mechanism. According to the invention, the automatic insertion and extraction of a power socket is realized during the field transfer of the gantry crane with a cable reel for power supply, the field transfer efficiency is improved, the safety hazards in the prior art are eliminated during the insertion and extraction of the power plug, the mechanism has the advantages of simple operation and control, and is safe, convenient and rapid, the maneuverability of the gantry crane can be improved greatly, thus under the premises of finishing the same operation amount, the quantity of used gantry cranescan be reduced.

Description

technical field [0001] The invention relates to a gantry crane powered by a cable reel, in particular to an automatic power-taking mechanism and an automatic power-taking method for the gantry crane. Background technique [0002] With the rise of oil prices and the improvement of environmental protection requirements, it has become a trend to change the power of container gantry cranes from fuel oil to electricity. An important link in the electric drive gantry crane technology is how to get the mains power to the RTG that needs to move over a long distance. [0003] A common method at present is to install cable reels and cables on the gantry crane, and power boxes, cable reels or movable joints are also needed in the middle of the yard. One end of the power cable on the gantry crane is connected to the power box in the middle of the yard, and is fixed on the ground through a cable reel or a movable joint. In this way, the utility power in the power box can be taken to th...
