Description
Technical field
The utility model belongs to technical field of metallurgical equipment, further belongs to steel billet conveying equipment technical field,
Be specifically related to one simple in structure, bearing capacity is large, durable reliable, easy to maintenance, hydraulic-driven step-by-step movement feeding skid.
Background technology
Feeding skid is one of auxiliary equipment important in metallurgy industry, and its Main Function is by technological requirement, blank or finished product to be delivered to the miscellaneous equipment of the other end from stand one end, to meet the requirement of production process.Feeding skid is mainly made up of two parts, i.e. moving beam and built-in beam, moving beam mostly is step-by-step movement structure, it holds up blank from built-in beam, step one stroke forward, then drop on built-in beam, then moving beam is got back to original position, carry out again next stroke, repeat above action, until blank is moved to the miscellaneous equipment of end from the top of built-in beam.In the production of bar or section bar, feeding skid is the visual plant before heating furnace in production line, and its effect is deposit steel billet and steel billet is delivered on furnace roller road one by one, to be transported to heating in stove.The feeding skid of prior art mainly contains three kinds of structures: machine driving step-by-step movement feeding skid, and chain transmission pull claw type feeding skid, hydraulic drive mobile cart type feeding skid, its main feature is as follows:
One, machine driving step-by-step movement feeding skid
Machine driving step-by-step movement feeding skid can be divided into driven by power transmission of crankshaft step-by-step movement, two kinds of structures of hydraulic-driven crank connecting link step-by-step movement according to prime mover.With electromagnetic lifter by steel billet after steel billet storage rack hangs feeding skid, steel billet moves to the nearest position of distance roller-way on feeding skid by stepwise operation, drops on roller-way.The advantage of this feeding skid is: reliable, and little to billet surface wearing and tearing; Owing to being machine driving, maintenance period is long, and maintenance amount is also relatively large.But in the time that the main shaft arm of force is maximum apart from design, the steel billet holding up is less, is generally less than 200 tons, more can not make long stand.Although machine driving step-by-step movement feeding skid structure is also simple, but crank mechanism installation accuracy is had relatively high expectations, whole equipment volume is larger, need to make larger foundation ditch and could meet installation, and do not use pusher dog, steel billet can not be realized the material loading rhythm taking 5 as 1 group, and when lift steel billet on stand time, steel billet length direction likely with stand center line out of plumb, when operation, can produce deflection, feed the feeding of furnace roller road and bring difficulty, can cause steel-fastening, the inseparable phenomenon of steel billet, sometimes also will install other Fen Gang mechanisms additional and just can meet the demands.
Two, chain transmission pull claw type feeding skid
Chain transmission pull claw type feeding skid, from structure, adopts chain conveying structure, by Motor Drive roller chain, roller chain two ends connect a dolly, are provided with pusher dog above dolly, pusher dog is fixed on dolly, drives pusher dog to promote steel billet move on table top by chain transmission.The structure of chain transmission pull claw type feeding skid is comparatively simple, and whole equipment volume is less, substantially can be arranged on ground level, concordant with rollgang, but that machine driving is connected with mechanism is more, and roller chain is shorter service life, and bearing capacity is less.A pusher dog is generally only installed on every chain, and therefore each circulation can only be carried one or a few steel billet, can not transport whole group or organize steel billet more, more can not accomplish to store up base ability to 20 groups or make long stand.Chain-drive billet feeding stand is generally only applicable to transfer large square billet or Hot Metal in Beam Blank, and conveying capacity and the lower occasion of efficiency, can not meet the production rolling power of our factory.
Three, hydraulic-driven pusher dog step-by-step movement feeding skid
Hydraulic-driven pusher dog step-by-step movement feeding skid adopts the moving beam stand of two Driven by Hydraulic Cylinder to do step-by-step movement motion, in order to solve stand stationary problem, and Driven by Hydraulic Cylinder two cranks, two cranks are connected on major axis simultaneously, and major axis connects with shaft coupling.On moving beam, the several roly-poly types of equidistant placement are cut somebody's hair, and roly-poly type is cut somebody's hair and can be rotated around axle, and moving beam stand returns, and in the time that steel billet is encountered at the back side of cutting somebody's hair, cuts somebody's hair and can take advantage of a situation, and passes from steel billet bottom surface.But this form feeding skid Driven by Hydraulic Cylinder crank, crank is again by driving major axis and connecting rod, connecting rod moves before and after pulling moving beam again, whole organization hydraulic pressure cylinder has the loss of thrust, force disperses, efficiency is not high, and mechanical type coupling part is more, design strength is generally not firm, mechanism wear is very fast, maintenance is larger, the dismounting cycle is longer, when dismounting, must could remove moving beam by determining after beam is removed, the long-time phenomenon that has distortion that uses of support body, and when moving beam pushes away steel billet forward, rely on connecting bolt to support pulling force, the easy fatigue fracture of bolt, generally can not make the long or larger stand of conduct storage base ability.
In sum, there is the defects such as noise is large, positioning precision is low, service life is short, manufacturing cost is high in the feeding skid of prior art.For this reason, research and development are a kind of simple in structure, and bearing capacity is large, and durable reliable, easy to maintenance, hydraulic-driven step-by-step movement feeding skid is the key addressing this problem.
