Description
Technical field
The present invention relates to a kind of concordant devices of coils of hot-rolled steel core pulling, belong to the concordant technical field in coils of hot-rolled steel core end face.
Background technique
Coil of strip core pulling be concordantly hot-continuous-rolling strip steel production in important process link, it is therefore an objective to realize that coiling machine is offline
Core of steel coil keeps concordant, it is ensured that subsequent coil of strip spray printing, bailing and coil of strip are smoothly offline, into the ring of commodity circulation
Section.
When coil of strip is detached from from the mandrel of coiling machine, due to the traction action of mandrel, the core part of coil of strip can be made not
It with degree is stretched out from core and forms tower-like, generation core pulling phenomenon.This not only influences the quality of coil of strip, makes the side of coil of strip
Out-of-flatness, it is often more important that, since the equipment such as the online spray printing of coil of strip conveying system, bundling have working space requirement, work as generation
When core pulling, width of steel coil broaden will cause spray head break, bundling failure, prevent coil of strip from smoothly it is offline.
For coil of strip horizontal roll means of transportation, the concordant device of coil of strip more common at present uses doublebeat plate shown in FIG. 1 two sides
The mode squeezed simultaneously.It is had the final say by two sides Hydraulic Cylinder, realizes that coil of strip is concordant, while setting is led in power hydraulic cylinder two sides
To lever apparatus, guidance clappers stable operation.But the device structure mode has the following problems:
1, the power of two sides clappers is transferred directly to foundation of civil work, and shearing force is very big, and foundation of civil work will not only bear to set
Standby self weight, still suffers from shearing force, requires foundation of civil work high；
2, equipment running space requires larger, causes hydraulic cylinder travel excessive, cantilever is too long, and stabilization of equipment performance is poor.Together
When due to clappers be in cantilevered structure end, easily guiding device is caused to deform, it is stuck, cause rolling line to stop production when serious, equipment
Failure rate is higher；
3, due to being the hardened structure of bilateral doublebeat, synchronism is not easy to guarantee exist coil of strip unilateral side overthrowing risk.
Summary of the invention
Technical problem to be solved by the present invention lies in a kind of concordant device of coils of hot-rolled steel core pulling is provided, job stability is high
And foundation of civil work is required low.

Dynamic, entire concordant trolley moves backward, until the concordant arm of concordant trolley is contacted with coil of strip other end, at this time drawback cylinder with
The movement of concordant trolley and retract.Operating cylinder works on, and realizes that coil of strip core pulling is flat by the extruding force of push plate and concordant arm
Together.After coil of strip is concordant, operating cylinder drives push plate to retract, while drawback cylinder works, and pushes concordant trolley mobile forward
To work initial bit.
Further, in order to realize the steady movement of concordant trolley, make being more uniformly stressed for steel coil end-face, the guide rail
Quantity is two, and the trolley idler wheels group is divided into two rows and is mounted on two guide rails, and every row's trolley idler wheels group at least has forward and backward
Two idler wheels.
Further, in order to reduce the center of gravity of upper beam, the structure of upper beam is rationally utilized, and reduce trolley idler wheels group
By coils of hot-rolled steel heat radiation, two rows of trolley idler wheels groups are symmetrically mounted on the two sides at the top of upper beam.
Further, in order to reduce influence of the coils of hot-rolled steel heat radiation to upper beam, the upper beam and concordant arm with
And thermal insulation board is respectively laid with the interconnecting piece of support arm.
Personnel safety when further, in order to ensure service work enhances overall structure stability, the braced frame
Two sides are equipped with safe fence, and brace is connected between braced frame and column.
Further, the side of concordant arm steel coil end-face opposite with push plate is mounted on wearing plate.
Further, in order to increase working space, the drawback cylinder and operating cylinder share a set of hydraulic system.
Further, in order to increase the stability of hanging frame, keep push plate mobile steady, the hanging frame further includes two
The track girder perpendicular to sliding rail is moved towards, the sliding rail is fixed between two track girders, and the section of sliding rail is I-shaped, described
Guide wheel group is by two guide wheel groups at two directive wheels are mounted on the two sides of I-shaped sliding rail.
Further, the guide rail is made of I-steel.
Compared with prior art, the beneficial effects of the present invention are:
1, the device is not transferred to Equipment Foundations to the concordant power of coil of strip, and device foundation of civil work on load bearing equipment is certainly
Weight, stress straight down, therefore foundation of civil work require it is low.
2, the concordant arm of concordant trolley is driven by the same operating cylinder with clappers being squeezed two end faces of coil of strip,
Concordant power is active force and reaction force, can be realized self-balancing, avoids the risk for overthrowing coil of strip.
3, concordant trolley is suspended on the guide rail of braced frame, and job stability is high when large span.It can satisfy large span
Transportation system, equipment operation stability is high, and maintenance is convenient.
