Detailed Description
Referring to fig. 1 to 3, in the anti-collision structure between the bridge cranes, the bridge cranes travel on the rails 10 arranged transversely, wheels 22 are arranged on the bases 20 of the bridge cranes, the wheels 22 travel on the rails 10, and a certain safety distance is kept between adjacent bridge cranes under normal conditions. The base 20 is provided with an emergency stop switch 30 for controlling emergency braking of the wheel, when the distance between the two bridge cranes is smaller than a safe distance, the emergency stop switch 30 can be started to prevent the bridge cranes from colliding, and the working principle of the emergency stop switch 30 is the conventional structure and is not introduced too much.
The bases 20 of the two oppositely arranged bridge cranes are respectively provided with transverse arms 24 extending towards each other, and the transverse arms 24 of the two bridge cranes are arranged in a vertically staggered manner, so that the transverse arms 24 of the two bridge cranes are prevented from colliding. Of the two oppositely disposed bridge cranes, the emergency stop switch 30 of one bridge crane is disposed at the front end of the bottom surface of the transverse arm 24 thereof, the emergency stop switch 30 of the other bridge crane is disposed at the front end of the top surface of the transverse arm 24 thereof, and the respective transverse arms 24 of the two bridge cranes are horizontally aligned with the emergency stop switches 30 of the other bridge crane. That is, when the two bridges are in close proximity to each other, the respective transverse arms 24 will push against the opposite scram switch 30, triggering the scram switch 30 and both bridges will stop.
Because the transverse arms 24 of the two bridge cranes are staggered and do not collide, the structure of the transverse arms 24 is kept good, and the transverse arms 24 can accurately strike the emergency stop switch 30 each time to realize parking operation.
In the embodiment, the emergency stop switch 30 is rotatably disposed on the transverse arm 24, and the transverse arm 24 pushes the emergency stop switch 30 to rotate and then starts the emergency stop switch. Thus, when the transverse arm 24 impacts the emergency stop switch 30, the emergency stop switch is triggered in the natural rotation process, and the transverse arm 24 can be abducted to prevent the transverse arm 24 from impacting the emergency stop switch 30.
Preferably, the end of the scram switch 30 is provided with a pulley 32, and the pulley 32 is in sliding contact with the outer surface of the transverse arm 24, so that the transverse arm 24 slides more easily over the scram switch 30. In particular, the front end face of the transverse arm 24 is an arc-shaped face, but may be a slope, which has a guiding effect on the pulley 32.
In addition, the bases 20 of the two oppositely arranged bridge cranes are respectively provided with oil cylinders 26 extending towards each other, so that the oil cylinders 26 of the opposite sides can play a role in buffering collision when the bridge cranes cannot completely brake due to overlarge inertia. It is of course preferred that the cylinders of the two bridges are aligned linearly and that the length of the cylinder 26 is less than the length of the transverse arm 24. Preferably, the cylinder 26 is located directly below the transverse arm 24.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
