Technical Field
[0001] The utility model belongs to the technical field of gantry cranes, and in particular relates to an anti-collision device for gantry cranes. Background Art
[0002] Gantry crane, also known as gantry crane or portal crane, is a heavy lifting machinery commonly used for cargo handling. Its name comes from its structural shape similar to the gantry in traditional Chinese architecture. It has the advantages of strong structure, large lifting capacity and wide application range.
[0003] Gantry cranes are widely used in loading and unloading, stacking and lifting of workpieces in ports, warehouses, factories, workshops and other places. Specifically, it is often used for port operations such as container lifting, cargo loading and unloading, stacking, etc., construction site lifting of building materials, prefabricated components, etc., industrial production line lifting and handling of heavy machinery, automobiles, etc., as well as railway station cargo transportation, locomotives, and vehicles entering and leaving the warehouse, etc. In addition, gantry cranes are also used for loading and unloading in mining.
[0004] The structure of the gantry crane includes a metal door-shaped frame, two legs are installed under the load-bearing main beam, and it can walk directly on the track on the ground. The two ends of the main beam can have an outward cantilever beam. According to the different door frame structure forms, main beam forms and main beam structures, gantry cranes are classified into many types, such as gantry cranes, cantilever gantry cranes, single-girder gantry cranes, double-girder gantry cranes, etc. These different types are suitable for different working environments and lifting requirements.
[0005] Traditional gantry cranes may collide during movement. When the gantry crane collides with an object, the lifting equipment on the gantry crane is easily shaken by external impact, which may cause damage to the hoisted objects and even cause serious damage to the gantry crane itself. In view of this, we propose a gantry crane anti-collision device. Utility Model Content

At the same time, the two second fixed blocks 7 will respectively push the two sliding rods 6 to move along the two first sliding grooves 5. When the two sliding rods 6 move, the two rotating rods 4 will respectively rotate on the two first fixed blocks 3. At this time, the impact force generated by the collision will be Further reduce, wherein, when the third fixing block 8 moves toward the fixing plate 2, the third fixing block 8 will squeeze the anti-sliding block 12, so that the anti-sliding block 12 drives one end of the damping rod 11 to move slowly, and the anti-sliding block 12 compresses the first spring 13, at this time, the damping rod 11 will absorb the remaining impact force, ensuring that the impact force generated by the collision will not affect the overall device, when the multiple buffer plates 9 are no longer in contact with the objects, the multiple anti-sliding blocks 12 will be respectively reset by the rebound force of the multiple first springs 13, so that the multiple anti-sliding blocks 12 respectively drive the multiple damping rods 11 to reset;
