[0002] For gantry cranes, loaders, portal cranes and other rail-mounted cranes used outdoors in ports, docks, railways, etc., movement under sudden strong winds will cause disastrous accidents such as overturning. To avoid such accidents, a windproof iron wedge is a commonly used protection device.

[0003] In the prior art, the Chinese utility model patent document with the authorization announcement number of CN215048098U discloses a new type of hydraulic self-locking anti-climbing device, which drives the iron wedge connecting rod to swing in a hydraulic manner and places the anti-slip wedge block under the wheel tread surface. When a sudden gust of wind blows the crane, the wheel pressure of the crane on the anti-slip wedge block can generate a sliding friction force between the anti-slip wedge block and the rail surface, preventing the crane from creeping and wedging the whole machine to play a safety protection role; this driving method has a complex structure, a high maintenance cost, and a large operating noise.

[0004] Therefore, it is necessary to design an electric magnetic lock type windproof iron wedge with a simplified structure, reduced maintenance cost and reduced operating noise to solve the current technical problems. Summary of the Invention

The iron wedge 4 inserted between the wheel 500 and the track 200 can prevent the wheel 500 from moving on the track 200, thereby achieving a windproof effect. In this embodiment, the driving motor 58 is used to drive the rotating shaft 53 to rotate, and the rotating shaft 53 drives the iron wedge connecting rod 3 to slide on the outside of the hosting 6 through the takeover plate 54, so that the iron wedge 4 at the bottom end of the iron wedge connecting rod 3 can be inserted between the wheel 500 and the track 200, and a sliding friction force is generated between the iron wedge 4 and the top of the track 200 to prevent the crane from crawling and wed the entire machine. The driving mode of the driving motor 58 is used to drive the iron wedge 4 to move, without the need to arrange complex hydraulic pipelines, simplifying the structure, reducing maintenance costs, and at the same time, the noise during operation is low.

[0025] In some embodiments, a locking plate 55 is fixedly provided on the rotating shaft 53, a locking hole 551 is provided on the end of the locking plate 55 facing away from the rotating shaft 53, and an electromagnetic lock 7 matching the locking hole 551 is provided on the side plate 2; after the iron wedge 4 at the bottom end of the iron wedge connecting rod 3 is pulled out from the wheel 500 and the track 200 and lifted into place, the locking hole 551 just corresponds to the electromagnetic lock 7, and at this time the electromagnetic lock 7 is controlled to operate so that its bolt is inserted into the locking hole 551 to lock the locking plate 55. After the locking plate 55 is locked, the rotating shaft 53 and the iron wedge connecting rod 3 are also locked, so that the iron wedge 4 can maintain a certain height between the track and the wheel, and does not affect the movement of the wheel on the track.

[0026] In some embodiments, a positioning plate 552 integrally structured with the locking plate 551 is fixedly provided on the locking plate 551. At one end of the positioning plate 552 facing away from the locking plate 551, a limiting lever 553 is vertically provided.

When the wedge link 3 is lifted to pull the wedge 4 out from between the wheel 500 and the track 200 to the upper limit position, the limiting lever 553 contacts the first travel switch 555 to trigger the first travel switch 555. By collecting the trigger signals of the first travel switch 555 and the second travel switch 556 and linking them with the drive motor 58, the drive motor 58 can be stopped in time after the movement reaches the position. Additionally, the position of the wedge 4 can be identified by collecting the trigger signals of the first travel switch 555 and the second travel switch 556.

[0027] In some embodiments, one end of the coupling plate 54 facing away from the rotating shaft 53 is hinged to the upper end of the wedge link 3 through a pin shaft 57. A spring support shaft 561 is fixedly provided on the side plate 2 below the rotating shaft 53, and a tension spring 56 is provided between the spring support shaft 561 and the pin shaft 57. When the wedge 4 at the bottom end of the wedge link 3 is inserted between the wheel 500 and the track 200 to wedge the wheel 500, under the elastic force of the tension spring 56, the wedge 4 can be kept in the state of wedging the wheel 500 to prevent it from loosening.

[0028] In some embodiments, a driven gear 52 is assembled on the outer side of the rotating shaft 53, and a driving gear 51 meshing with the driven gear 52 is provided on the drive motor 58. By designing different transmission ratios between the driving gear 51 and the driven gear 52, a greater torque can be output by the rotating shaft 53.

[0029] In some embodiments, as Figure 2 and 3 shown, the lower end of the wedge link 3 has an L-shaped elbow 31, and the upper part of the wedge 4 is rotatably connected to the L-shaped elbow 31.
