Abstract
A volute type shield for an approach table of a cooling bed of a continuous section steel rolling line belongs to the cooling bed of the continuous section rolling line, and particularly relates to a safeguard for the approach table of the cooling bed of the continuous section steel rolling line. The volute type shield is characterized in that: a framework type base is arranged on a concrete foundation, at least three rib plates are symmetrically arranged on the framework type base, a shield which is composed of a head-on curved baffle and side vertical plates is arranged on the rib plates, the opening direction of the shield is opposite to the approach table, and the bottom of the head-on curved baffle is tangently connected with the plane of the approach table. The volute type shield has the advantages that: the design is novel, and the structure is simple, compact and reasonable; the floor area occupied by the volute type shield is small, so the volute type shield is suitable for the limited basic space at the end of the approach table; the adoption of the head-on curved baffle can ensure that the head of a piece of section steel can be curved along the internal wall of the head-on curved baffle, effectively reducing impact force, consequently, the safety baffle can be prevented from being damaged after being impacted by the rolled section steel piece, the service life is prolonged, the consumption of spare parts is reduced, the production cost is reduced, potential safety hazards are eliminated, and smooth production process is ensured.
Description
Technical field
The utility model belongs to continuous section rolling line cold bed, relates 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 consists 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, by foundation bolt, is fixed on concrete pedestal; 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.During 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 leaves the speed with 3 meter per seconds left and right after flying shear and is transported to cold-bed run-in table, then goes up cold bed and carries out cooling.In process of production, often because of shaped steel length of rolled piece, surpass the preseting length of cold bed, 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 when 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.
Utility model content
The defect existing in order to overcome prior art, the purpose of this utility model 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 utility model 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, by foundation bolt, is fixed on concrete pedestal; 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 utility model 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 two ends weld side riser of curved baffle head-on, 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 utility model 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 utility model 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 half that the height of reinforcement is the curved baffle height that heads on, for level and longitudinal supporting protection cover of strengthening.
Compared with prior art, advantage is novel, and structure letter gathers, rationally; The utility model floor space 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.
