Description
Technical field
The invention belongs to continuous section rolling line cold bed, relate in particular to a kind of safety device of continuous section rolling line cold-bed run-in table.
Background technology
Cold bed is one of continuous section rolling production line visual plant, be located at the rear of flying shear, for specification, to be H continuous section rolling line cold bed below 400 × 200mm promoted by approach table, approach table end safety screen, cold bed entrance side rolled piece (being shaped steel) that skirtboard, cold bed determine beam, cold bed moves beam, lower trolley and cold bed runout table and forms.Its safety screen is made up of the concrete pedestal, base and the upright baffle that are located at approach table end, and upright baffle and approach table axis are vertically welded on base, and through hole is established in base both sides, is fixed on concrete pedestal by foundation bolt; Reinforcement is established at the upright baffle back side, and the welding of reinforcement lower end and base prevents the shaped steel rolled piece approach table that flies out.When rolling production, the shaped steel that continuous section rolling machine shuts out by flying shear cut into approximately 75 meters of length, the shaped steel rolled piece of 2.8 tons of weighing, shaped steel rolled piece is transported to cold-bed run-in table with the speed of 3 meter per seconds left and right after leaving flying shear, then goes up cold bed and carries out cooling.In process of production, often exceed the preseting length of cold bed because of shaped steel length of rolled piece, cause rolled piece to clash into safety screen accident, or operate under automated manner because of cold bed, on cold-bed run-in table, there is rolled piece, hot metal detector does not detect rolled piece in time, to such an extent as to promoting skirtboard, cold bed rolled piece fails in time rolled piece to be mentioned, cause rolled piece to clash into safety screen accident, or operate under manual mode because of cold bed, and operative employee thinks that cold bed operates under automated manner by mistake, cause rolled piece to clash into safety screen accident.The defect existing is in the time that rolled piece clashes into safety screen accident, up to 1000 ℃, weight reaches the shaped steel rolled piece of 2～3 tons and directly bumps against with upright baffle with the speed of 2.5～4 meter per seconds, huge impulsive force easily causes base set bolt to rupture, service life is short, often need to change spare part, spare parts consumption is large, increases production cost, and more seriously baffle plate topples, shaped steel rolled piece flies out, security incident occurs, cause personal injury, what impact was produced normally carries out; After shaped steel rolled piece and baffle effect, distortion is serious, can not meet follow-up technological requirement, can only again melt down utilization as steel scrap, and production efficiency is low.
Summary of the invention
The defect existing in order to overcome prior art, the object of this invention is to provide a kind of continuous section rolling line cold-bed run-in table scroll casing type guard shield, simple in structure, effectively alleviate impulsive force, increase the service life, reduce spare parts consumption, reduce production costs, eliminate safe hidden trouble, guarantee carrying out smoothly of production.
Continuous section rolling line cold-bed run-in table scroll casing type guard shield, comprise approach table, be located at the concrete pedestal of approach table end, on concrete pedestal described in being characterized in, establish frame-type base, on frame-type base, at least symmetry is established three gussets, on gusset, establish by the protective cover that head-on curved baffle and cant board form, the opening direction of protective cover is with relative with approach table, and head-on curved baffle bottom surface is connected with approach table plane is tangent.When thering is the shaped steel rolled piece of certain speed and protective cover and occurring to clash into, protective cover makes shaped steel head bend along the curved baffle inwall that heads on, enormous impact power major part is converted to the vertical force that shaped steel head is bent, greatly reduces the suffered horizontal impact power of whole device.
The present invention further improves, and described base is rectangle frame posture structure, the vertical approach table center line of broadside, and the bilateral symmetry of base is established through hole, is fixed on concrete pedestal by foundation bolt; The bottom of the base sliding muscle of setting up defences, anti-skidding muscle is cross, upper end and base welding, lower end is placed in concrete pedestal, the horizontal shear force that while reducing shaped steel crash cover, base set bolt bears.
The present invention further improves, described protective cover is by head-on curved baffle and cant board form, head-on curved baffle is rolled and is surrounded scroll casing shape by the steel plate that at least 15mm is thick, and the central angle of spiral case housing is greater than 180 °, and the width of baffle plate is slightly larger than the width of cold-bed run-in table; The head-on two ends weld side riser of curved baffle, it is fan-shaped that cant board is, and the fan-shaped center of circle is with the center of circle of curved baffle head-on on same straight line, and longitudinal bracing baffle plate, strengthens the rigidity of baffle plate.
The present invention further improves, and described gusset is provided with the arc surface with the curved baffle identical radian measure that heads on, and arc surface bottom tangent and approach table face are in same level, and guarantee to head on curved baffle entrance and roller-way face are tangent; Gusset lower end is welded on base, and upper surface flushes with the center line of the curved baffle that heads on.
The present invention further improves, and reinforcement is established at the described head-on back side of curved baffle, and reinforcement is welded on base according to identical spacing, and the height of reinforcement is the half of curved baffle height head-on, for level with longitudinally strengthen supporting protection cover.
Compared with prior art, advantage is novel, and structure letter gathers, rationally; Floor space of the present invention is little, is applicable to the limited basic space of approach table end; Adopt head-on curved baffle can make shaped steel head bend along the curved baffle inwall that heads on, effectively alleviate impulsive force, make safety screen after shaped steel rolled piece clashes into, exempt from damage, increase the service life, reduce spare parts consumption, reduce production costs, eliminate safe hidden trouble, guarantee carrying out smoothly of production.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is continuous section rolling line cold-bed run-in table scroll casing type shield structure schematic diagram.
In figure: 1-shaped steel rolled piece, 2-approach table, 3-head on curved baffle, 4-gusset, 5-reinforcement, 6-cant board, 7-base, 8-concrete pedestal, the anti-skidding muscle of 9-.
