Description

Crown block guard device in metallurgical industry Technical Field The utility model relates to the field of crown blocks, in particular to a crown block guard device in the metallurgical industry. Background Crown blocks (also called bridge cranes) in the metallurgical industry are indispensable equipment on production lines and are responsible for handling various heavy materials such as billets, blooms, scrap steel and the like, however, due to the specificity of metallurgical environments such as high temperature, high dust, strong electromagnetic interference and the like, certain potential safety hazards exist in the operation of crown blocks. In order to ensure production safety and reduce accident risk, crown block guard devices have been developed. The existing crown block in the metallurgical industry generally adopts a steel wire rope to hoist articles, and the articles are manually supported for mobile hoisting. Then, because current overhead traveling crane adopts single wire rope to hoist and mount generally, scram the overhead traveling crane when wanting the collision, article can incline forward because of inertia, and the manual work can be by the drag force associated forward dumping, can't avoid article forward dumping when scram, leads to operating personnel to receive the injury, proposes a metallurgical industry overhead traveling crane guard device for this and solves above-mentioned problem. Disclosure of utility model In order to make up for the defects, the utility model provides an overhead travelling crane guard device in the metallurgical industry, and aims to solve the problem that articles cannot be prevented from tilting forward when the articles are suddenly stopped in the prior art. In order to achieve the purpose, the technical scheme is that the overhead travelling crane guard device in the metallurgical industry comprises two groups of trolley bodies, transverse frames are fixedly connected between the two groups of trolley bodies, transverse carriages are slidably connected to the outer walls of the transverse frames, extension discs are fixedly connected to the bottoms of the transverse carriages, motors are fixedly connected to the tops of the extension discs, rope discs are fixedly connected to the output ends of the motors, hanging rings are connected to the rope discs through cables, supporting frames are fixedly connected to the tops of the extension discs, and guide grooves are formed in the tops of the extension discs. As a further description of the above technical solution: the motors are provided with four groups, and the four groups of motors are circumferentially distributed on the top of the motor by taking the extension disc as a center. As a further description of the above technical solution: the end part of the rope disc is rotatably connected to the inner wall of the supporting frame. As a further description of the above technical solution: the cable is wound on the outer wall of the rope disc, and the tail end of the cable is fixedly connected to the top of the hanging ring. As a further description of the above technical solution: the guide grooves are provided with four groups, and the mooring ropes respectively pass through the four groups of guide grooves. As a further description of the above technical solution: The two groups of the vehicle body bottoms are provided with travelling wheels which are symmetrically distributed by the central axis of the transverse frame. The utility model has the following beneficial effects: 1. According to the utility model, the extension disc, the motor, the rope disc, the mooring rope, the supporting frame, the guide groove and the hanging ring are arranged, when the bottom hanging article is prevented from being impacted, the vehicle body is driven to move through the travelling wheel, then the bottom hanging article is driven to move along with the vehicle body, then when the article is to be impacted, the vehicle body is driven to stop through the remote control emergency stop travelling wheel, meanwhile, the motor opposite to the moving direction is controlled to rotate the winding mooring rope through the emergency stop program, a reverse pulling force is provided for the hanging article, the article is prevented from moving forward due to inertia, and the effect of protecting the hanging article from collision is achieved. 2. According to the utility model, the extension disc, the motor, the rope disc, the mooring rope, the supporting frame, the guide groove and the hanging ring are arranged, and in the hanging process, the four groups of mooring ropes are used for hanging the article in an inverted cone shape, so that multidirectional traction is provided for the article, the shaking amplitude of the article is reduced, and the injury to operators caused by the shaking of the article in a large amplitude is avoided.
