A kind of more changing device
The utility model relates to a kind of more changing device, and especially a kind of more changing device of milling train stand import guide and guard belongs to the rolling machinery technical field.
During modern steel is produced, milling train one of the equipment that is absolutely necessary, it can be processed into billet rolling the steel of all size performance.Steel billet import department on the milling train is provided with the guide and guard that the guiding steel billet enters, because a large amount of contact steel billet, thereby the wearing and tearing of guide and guard are quite serious, so want often the guide and guard that damage to be changed.Yet traditional replacing is finished by manpower entirely, and guide and guard are parts of a kind of heaviness, so carrying and replacing are all very difficult.Doing not only like this wastes time and energy, and influences operating efficiency, also has great potential safety hazard.Therefore, be necessary fully prior art is improved.
Summary of the invention
Because existing guide and guard are changed and can only be finished by manpower, thereby cause labour intensity excessive, have problems such as very big potential safety hazard, the utility model provides more changing device of a kind of quick, safe guide and guard, to address the above problem.
The utility model is finished by following technical proposal: a kind of more changing device, it is characterized in that comprising the main body base of establishing hanger on it, and establish the jaw and the balance weight hanging bar of band securing member on the main body base.
Described main body base is made as cuboid or cylinder.
Described hanger is made as former and later two, the previous main body base front end that is installed on, and back one is installed on main body base middle part, so that the convenient equalization point of selecting during lifting.
The jaw of described band securing member is located at the main body base front end, and this jaw is divided into two, and each jaw is provided with securing member, is placed jaw so that hang the end of guide and guard or other parts, and after fixing by securing member, promptly the right side is lifted by crane by crane.
Described securing member is made as bolt or latch or pin.
Described balance weight hanging bar is located at both sides, main body base rear end, suspension active counterweight on the balance weight hanging bar, so that when changing guide and guard or other parts, counterweight is hung in increase and decrease or replacing as required, to play a balanced action.
The utility model compared with prior art has following advantage and effect: adopt such scheme, can carry out guide and guard safely and fast and change, change operation changed into machinery by original artificial replacing operation, improved replacing efficient greatly.Owing to adopt mechanically actuated, reduced potential safety hazard.Become 2 people's operations by original 5 people operation simultaneously, saved limited human resources, improved efficient, increase economic benefit for enterprise to greatest extent.It in fact is more changing device of a desirable rolling mill guiding.
