[0002] At the container terminal, the bridge crane is the main force of container operations. The operating mechanism of the bridge crane is divided into four mechanisms: lifting, pitching, trolley and cart. The trolley mechanism is laid on the rails on the rail beam. After a long period of use, the tracks and track pressure plates on the rail beam often need to be maintained and replaced. During maintenance, cutting and welding of tracks, pressure plates, etc. require gas welding for cutting and trimming, and electric welding is used for welding. When using electric welding and gas welding, a large amount of sparks and iron oxide will fall from the rail beam. If there are flammable and explosive items under the rail beam, it will cause a fire, posing a major safety hazard. Once the rail beam is located above the ship, welding slag will fall due to electric welding and gas welding, and maintenance work on the rail beam cannot be carried out, affecting the normal use of the bridge crane and causing economic losses.
[0003] CN 219567333 U discloses a welding slag collector and a bridge crane. The welding slag collector can be clamped on the rail beam through a clamping part, and then the welding slag and sparks dropped from the rail welding on the rail beam are collected through a receiving part located at the bottom, thereby reducing the occurrence of pollution, avoiding the falling of welding slag and sparks, and avoiding the occurrence of safety accidents. The patent clamping part is arranged at the front edge of the baffles on both sides. After clamping the rail beam, the use of electric welding is restricted, and the welding slag cannot be well blocked. At the same time, the patent clamping part needs to manually adjust the angle to block the welding slag, which is inconvenient to use during actual welding. Utility Model Content
