Description

Technical Field

[0001] The utility model relates to the technical field of furnace front equipment of an ore-fired furnace, in particular to a drill rod disassembly and installation device. Background Art

[0002] The drill rod replacement device is a device used to replace the drill rod of the eye-opening machine in front of the blast furnace. It belongs to the auxiliary equipment in front of the furnace. Its main function is to use mechanical automation to replace the manual replacement of the drill rod (the drill rod is burned after drilling, and a new drill rod needs to be replaced for the next drilling). It saves time, labor and is safe. It can form an unmanned fully automatic operation mode together with the equipment in front of the furnace. The equipment in front of the blast furnace is small, and there is enough space at the standby position of the eye-opening machine. Therefore, the rod replacement device is fixed near the eye-opening machine. When the eye-opening machine is in the standby position, the drill rod replacement device is started to replace the drill rod so that the iron mouth channel can be opened next time.

[0003] At present, the drill rod replacement technology mostly adopts the automatic rod replacement method, which generally stores the drill rods through a rod storage device, and replaces the rods by moving the rod storage device or further combining other auxiliary devices (such as a feeding mechanism). Among them, the rod storage device in the prior art only stores the drill rods separately. When the drill rods are sent to the bottom of the eye-opening machine rail beam, the drill rods need to be separated first, and then grabbed and placed on the drill rod feeding mechanism. The entire rod replacement process requires a more complex extraction device to complete the actions of drill rod separation, grabbing and placing. The process is more complicated, the equipment is more, the unreliability is greater, the stability is poor, and the energy consumption is high, and the safety is also low. Utility Model Content
