Specifically, the gantry crane first runs to the deceleration limit, and the first group of first travel switches 111 hits the first group of first anti-collision auxiliary detection components 112 on the ground, so that the running speed of the first gantry crane 1 is reduced, and then the first gantry crane 1 continues to move, and will pass through the stop limit position and the extreme limit position in sequence, and finally the traveling mechanism of the first gantry crane 1 is stopped.

[0087] In this embodiment, preferably, the gantry crane anti-collision system also includes a third scanner (not shown in the figure, refer to the first gantry crane 1 for details), and the third scanner is arranged on the second cross beam 21 and maintains a third preset distance from the second rigid leg, and preferably, the third scanner is a laser scanner. Of course, it is not limited to this, and it can also be other types of scanners.

[0088] According to the structure described above, when the second gantry crane 2 lifts a heavy object, when the distance between the heavy object and the second rigid leg is within a certain range, there is a risk that the heavy object will collide with the second rigid leg. To control the risk, a third scanner such as a laser scanner is installed on the second rigid leg of the first gantry crane 1. When the hoisted heavy object enters the range of the laser scanner, the laser scanner triggers an alarm to remind the operator to prevent risks and achieve the purpose of preventing collisions. Of course, there are many types of scanners, not limited to laser scanners, and they can also be selected according to actual needs.

[0089] In this embodiment, preferably, the gantry crane anti-collision system also includes a fourth scanner (not shown in the figure, refer to the first gantry crane 1 for details), the fourth scanner is arranged on the second beam 21, and maintains a fourth preset distance from the second flexible leg, and preferably, the fourth scanner is a laser scanner. Of course, it is not limited to this, and it can also be other types of scanners.

[0090] According to the structure described above, when the second gantry crane 2 lifts a heavy object, when the distance between the heavy object and the second flexible leg is within a certain range, there is a risk that the heavy object will collide with the second flexible leg. In order to control the risk, a fourth scanner such as a laser scanner is installed on the second flexible leg of the first gantry crane 1. When the hoisted heavy object enters the range of the laser scanner, the laser scanner triggers an alarm to remind the operator to prevent risks and achieve the purpose of preventing collision. Of course, there are many types of scanners, not limited to laser scanners, and they can also be selected according to actual needs.

[0091] In this embodiment, preferably, the second gantry crane 2 further includes a second traveling wheel mechanism, a plurality of second travel switches and a plurality of second anti-collision auxiliary detection components (not shown in the figure, for details, refer to the first gantry crane 1); wherein, the bottom of the second rigid leg and the bottom of the second flexible leg are both provided with a second traveling wheel mechanism, and the plurality of second travel switches are provided on at least one of the two second traveling wheel mechanisms;

[0092] Multiple second travel switches are arranged in sequence at intervals along the first preset direction a; multiple second anti-collision auxiliary detection components are arranged in sequence at intervals along the first preset direction a at the second target location, and multiple second travel switches correspond one-to-one to multiple anti-collision auxiliary detection mechanisms, and when the second walking wheel mechanism moves to the preset position, the second anti-collision auxiliary detection component can trigger the corresponding second travel switch.

[0093] Further, preferably, the number of second travel switches and second anti-collision auxiliary detection components are three, and correspond one to one. In order to facilitate the distinction between the second travel switches in different positions, they are named as follows: second deceleration limit travel switch, second stop travel switch and second over-limit travel switch. Of course, not limited to the above, the number of second travel switches and second anti-collision auxiliary detection components can also be less than three, such as two, or greater than three, such as four or five, and so on.

[0094] According to the structure described above, when the second gantry crane 2 walks to the top of the track ground, in order to stop the traveling mechanism of the second gantry crane 2, a second deceleration limit travel switch, a second stop travel switch and a second over-limit travel switch are respectively arranged on the trolley traveling mechanism of the second gantry crane 2, and three second anti-collision auxiliary detection components need to be arranged at the corresponding positions. Specifically, the gantry crane first runs to the deceleration limit, and the first group of second travel switches hits the first group of second anti-collision auxiliary detection components on the ground, so that the running speed of the second gantry crane 2 is reduced, and then the second gantry crane 2 continues to move, and will pass through the stop limit position and the extreme limit position in sequence, and finally the traveling mechanism of the second gantry crane 2 stops running.

[0095] In this embodiment, preferably, along the second preset direction b, the width of the first beam 141 of the first rigid leg 14 is greater than the width of the second beam 151 of the first flexible leg 15; along the second preset direction b, the width of the third beam 24 of the second rigid leg is greater than the width of the fourth beam of the second flexible leg.

[0096] Further, preferably, Fig.17As shown, the gantry crane anti-collision system also includes a rangefinder 7, which is arranged on one side of the first beam 141 along the second preset direction b. Of course, it is not limited to this, and the rangefinder 7 can be arranged only on both sides of the first beam 141 along the second preset direction b, or the rangefinder 7 is not arranged on the first beam 141 as mentioned above, but the rangefinder 7 is arranged on at least one side of the third beam 24 along the second preset direction b, or the rangefinder 7 is arranged on at least one side of the first beam 141 and the third beam 24 along the second preset direction b at the same time, and the specific selection is based on actual needs.

[0097] According to the structure described above, since the beams of the rigid legs are wider, it is only necessary to ensure that the beams of the rigid legs do not collide, and then the beams of the flexible legs will definitely not collide. Further, preferably, Fig.18 As shown, the gantry crane anti-collision system also includes a fifth anti-collision component 8, and the first beam 141 and the third beam 24 are both provided with the fifth anti-collision component 8 on the side close to each other along the second preset direction b, so that the spraying of the beams of the two gantry cranes can be effectively avoided. Of course, it is not limited to the above. The fifth anti-collision component 8 may be set on the third beam 24 of the second gantry crane 2 instead of the first beam 141 of the first gantry crane 1, or the fifth anti-collision component 8 may be set on the first beam 141 of the first gantry crane 1 and the third beam 24 of the second gantry crane 2 at the same time.

[0098] It should be noted that: it is not limited to that the fifth anti-collision component 8 is provided on one side of the first beam 141 and the third beam 24 that are close to each other along the second preset direction b, but the fifth anti-collision component 8 can also be provided only on the first beam 141 or the third beam 24, and the fifth anti-collision component 8 can be provided on one side or on both sides.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
