Abstract
The invention discloses a cooling bed thermal-insulation cover, which is characterized in that the cooling bed thermal-insulation cover comprises a driving device and two thermal-insulation covers, and is hinged via a hinge; the driving device is connected with the two thermal-insulation covers by a guide device; and under the function of the driving device, one thermal-insulation cover can rotate around the hinge and is folded and unfolded with the other thermal-insulation cover. The cooling bed thermal-insulation cover is provided with the folded thermal-insulation cover, the height of the opened thermal-insulation cover of the oil tank can be lowered while the effective width of the thermal-insulation cover is increased, the limitation on the width of the thermal-insulation cover by the lower edge elevation of a factory crane girder is solved, the deformation in the heating process of the thermal-insulation cover is relieved, the cooling temperature drop of the slow cooling collection material in a cooling bed area is reduced, and the high-temperature slow cooling time of the cold machining material is prolonged.
Description
Technical field
The present invention relates to a kind of stay-warm case, relate in particular to a kind of cold bed stay-warm case.
Background technology
In the modern steel rolling production-line, especially in middle-size and small-size production line of bar, dispose the big cold bed of stepping rack-and-pinion usually, to realize the long chi cooling of rolled piece, and then improve cooling effect and production efficiency, be convenient to the carrying out of operations such as follow-up shearing, bundling, collection simultaneously.Yet, for some special steel grades, easily produce the structural alloy steel of white point, under thermal stress and structural stress effect, easily produce the steel grade that ftractures as air cooling, need to reduce rolled piece at the cooling temperature drop in cold bed district, to guarantee after follow-up sawing operation, the entering temperature requirement that burial pit is collected; And the cold worked steel grade in downstream is carried out in some requirement, then need export high temperature section at milling train and carry out slow cooling to obtain comparatively thick crystal grain, in order to satisfy the cold working requirement of downstream industry.
For above-mentioned first kind steel grade, though considered the quick step function of stepping notch-bar cooling bed during design, be that the cooling capacity of cold bed common material of output must possess the higher machine of cooling simultaneously the time requires and the quick stepping of cooling off special material reduces the requirement of cooling temperature drop, but, temperature drop under the rolled piece reality during cold bed is still bigger, and that can't guarantee high temperature slow cooling material goes into to cheat temperature requirement.For the above-mentioned second class steel grade, require the cold bed entrance side to possess the interval condition of long slow cooling, namely slowly tide over the high-temperature region, therefore, at the cold bed entrance side process for cooling requirement that stay-warm case can satisfy two class steel grades is set.
Owing to be subjected to the restriction of crane crossbeam lower edge absolute altitude in the factory building, the width of existing cold bed stay-warm case is restricted, simultaneously owing to be subjected to the function restriction of long chi cold bed transportation rolled piece, multiple spot can't be set the cold bed stay-warm case or two point supports, only can be designed to cantilever structure, and the cold bed stay-warm case is operated in the hot environment, is heated easily to produce distortion.Under the limited condition of stay-warm case width, in order to satisfy the high temperature slow cooling requirement of the above-mentioned second class steel grade, generally need by reducing the stepping cadence time of cold bed, make rolled piece in cold bed stay-warm case width range, stop the longer time and reach the slow cooling purpose, but the enforcement of this scheme need reduce the rolling rhythm of main rolling line to be satisfied, the reduction of output when directly having caused the production line machine.
Summary of the invention
The object of the present invention is to provide a kind of cold bed stay-warm case that can increase the stay-warm case effective width.
The object of the present invention is achieved like this, a kind of cold bed stay-warm case, it is characterized in that: comprise two stay-warm cases and hinged by hinge, drive unit is connected with described two stay-warm cases by guider, and wherein a stay-warm case can be around described hinge rotation and the folding or expansion with another piece stay-warm case under the effect of drive unit.
Above-mentioned drive unit is line wheel drive module, comprises the line wheel A that is arranged on the driving shaft, two connecting lines is set and passes through above-mentioned guider on the described line wheel A to be connected with two stay-warm cases respectively.
Above-mentioned driving shaft is arranged on the bearing A by bearing block A.
Above-mentioned guider is line wheel oriented module, comprises line wheel B and is arranged on the rotating shaft B, and described rotating shaft B is arranged on the bearing B by bearing block B.
Be respectively equipped with Connection Block above above-mentioned two stay-warm cases and be connected with above-mentioned two connecting lines respectively, described Connection Block is provided with cushion pad.
Above-mentioned two stay-warm cases are arranged on the supporting seat, and described supporting seat comprises rotating shaft C and is arranged on the bearing C by bearing block C.
In order to reduce the driving force of drive unit, be provided with balance weight below the stay-warm case of a side of described supporting seat pin joint.
Two stay-warm cases are respectively by twining online wheel drive modules A and the connecting line on line wheel oriented module B provides support, and effectively solve the problem that the stay-warm case cantilever design can't two point supports.Therefore, cover cap of the present invention can possess bigger width, and can obtain stable support in hot environment, avoids must being out of shape under the high temperature.
In the stay-warm case opening procedure, at first by line wheel drive modules A connecting line is twined on online the wheel, thereby driving a stay-warm case rotates around hinge, after rotating through 90 degree, this piece stay-warm case can drop on another piece stay-warm case, at this moment in the effect of deadweight, the cushion pad that is arranged on the Connection Block can cushion this impact, and the upper surface of cushion pad can play the effect of location, and at this moment, two stay-warm cases are finished folding.By line wheel drive modules A connecting line is twined on online the wheel, thereby drive a stay-warm case around the axle rotation hinged with supporting seat C, after stay-warm case was opened and put in place, line wheel drive modules A stopped to drive and locking, and this moment, stay-warm case was finished opening procedure.Owing to adopted folding stay-warm case structure, so after stay-warm case opened, it highly can be effectively reduced, thereby avoids factory building crane crossbeam to the influence of stay-warm case width restriction.
The present invention has following beneficial effect: the present invention arranges collapsible stay-warm case, two stay-warm cases provide support by the connecting line that is arranged on drive unit and the guider respectively, efficiently solve the problem that existing stay-warm case cantilever design can't two point supports, therefore, cover cap can have bigger width, and can in hot environment, obtain stable support, overcome the distortion under the high temperature.Reduce slow cooling and collected material at the cooling temperature drop in cold bed district, and increased the high temperature slow cooling time of cold working material.
