Abstract

The utility model provides a replacing device. The utility model is characterized in that the replacing device comprises a main seat that is provided with a lifting lug, wherein a jaw and a counterweight suspension rod are arranged on the main beat, and the jaw is provided with a fastener. Therefore, the guide replacement can be realized safely and fast, and the original manpower replacement operation is changed into the mechanical replacement operation, thereby greatly improving the replacement efficiency. By adopting the mechanical manipulation, the potential safety hazard is reduced. The number of workers for completing the operation can be changed from the original five to two, thereby saving the limited manpower resource, improving the efficiency, and increasing the economic benefit for the enterprises to the maximum limit, therefore, the ideal guide replacing device of a rolling mill is provided.

Description

A kind of more changing device

Technical field

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.

Technical background

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.
