Abstract
A beam frame of a bar screen mesh belongs to the screening technical field and comprises a frame body with a hollow cavity, a pair of coaxial bar mounting holes and a bar fixing device. The beam frame is characterized in that ribs are welded and fixed on the rectangular frame body and under the bar mounting holes; a pair of wedge bar mounting holes in parallel with the axle center of the bar mounting holes are arranged on the lower part of the frame body; the wedge bars with wedge angles are positioned inside the wedge bar mounting holes and fixedly welded to the frame body; the hollow cavity of the frame body over the wedge bars is provided with an elastic gasket and a rigid gasket from bottom to top. The dip angles of the strengthening ribs can keep same direction with the exciting force of the screening machine, or can be perpendicular to the bottom surface of the frame body. The utility model not only improves the rigidity of the beam frame, but also makes the bars be more firmly mounted. The utility model can be applied to large-size and large tonnage screen meshes.
Description
Described technical field
A kind of roof beam structure of rod screen cloth belongs to the material sieving technology field.
Background technology
At present, with regard to the screening situation, bar screen is used in a large number in the sieve type simple as a kind of manufacturing process, that screening efficiency is higher and service life is long, but the roof beam structure that is now using exists some shortcomings: it is relatively poor as its manufacturability of roof beam structure of garden shape to pass cross section as rod; Passing cross section as rod is that its rigidity of roof beam structure of U-shaped is also relatively poor, and in large scale, large-tonnage screen cloth, the problem that is caused by the rigidity fixing and roof beam structure of grating is particularly outstanding.
Summary of the invention
For solving above-mentioned outstanding problem, the purpose of this utility model just provides a kind of roof beam structure of rod screen cloth, makes it better on rigidity, more reliable to fixing of rod.
Its technical scheme is the roof beam structure of this kind rod screen cloth, comprises the support body of being with cavity, the rod installing hole of a pair of concentric and rod fixture, it is characterized in that be positioned on the support body of described rectangle the rod installing hole below solid welding rib is arranged; Be provided with wedge rod installing hole a pair of and rod installing hole axis parallel in the bottom of support body, the wedge rod that has the angle of wedge places in it and in the support body solid welding; Be provided with elastomeric pad, rigid gasket from bottom to top in the support body cavity on the wedge rod.
Further, the bottom surface of support body is provided with reinforcement.The inclination angle of this reinforcement is consistent with the exciting force direction of screen(ing) machine, also can be perpendicular to the support body bottom surface.
The beneficial effects of the utility model are owing to adopted rectangle support body and reinforcement, have improved the rigidity of roof beam structure; Owing to be provided with rib, the crooked also solid welding of one end is on rib during the rod assembling, and it is more firm by wedge rod and resilient sleeper-bearing, rigidity backing plate rod to be installed simultaneously.
Description of drawings
Be elaborated below in conjunction with accompanying drawing.
Fig. 1 is the schematic top plan view of embodiment beam frame structure;
Fig. 2 is the A-A cutaway view of Fig. 1.
Wherein, 1-rod, 2-support body, 3-resilient sleeper-bearing, 4-rigidity backing plate, 5-wedge rod, 6-rib, 7-reinforcement.
The specific embodiment
As Fig. 1, Fig. 2, the roof beam structure of this kind rod screen cloth comprises the support body 2 of being with cavity, the rod installing hole of a pair of concentric and rod fixture, the below solid welding that is positioned at the rod installing hole on the support body 2 of described rectangle has rib 6, and this rib 6 can be a square cylinder, also cylinder; Be provided with wedge rod installing hole a pair of and rod installing hole axis parallel in the bottom of support body, the wedge rod 5 that has the angle of wedge places in it and in support body 2 solid weldings; Be provided with elastomeric pad 3, rigid gasket 4 in the support body cavity on wedge rod 5 from bottom to top, the bottom surface of support body 2 is provided with reinforcement 7.
Implementation process is after elastic metallic rod 1 passes the rod installing hole of a pair of concentric of holing by the setting pitch-row on the support body 2, the afterbody that rod 1 is stretched out twists on rib 6, then its point is welded on the support body 2, this can prevent rod 1 axial float and rod can't be rotated.In the support body chamber of rectangle below the rod wedge rod 5 of flexible backing plate 3 rigidity backing plates 4 through having the angle of wedge when penetrating, rod compressed by sidewall and with the solid welding of wedge rod on support body, its effect is that shake is worn and torn when eliminating the work that rod and the fit-up gap between the rod installing hole causes; Cross section is that the support body shape of rectangle and band reinforcement makes it rigidity and is improved, and roof beam structure rigidity is met when requiring the screen cloth width dimensions big.The angle of the reinforcement 10 that described roof beam structure bottom surface is provided with is consistent with the exciting force direction of screen(ing) machine, or perpendicular to the bottom surface of support body.
Claims (4)
1, a kind of roof beam structure of rod screen cloth comprises the support body of being with cavity, the rod installing hole of a pair of concentric and rod fixture, it is characterized in that be positioned on the support body of described rectangle the rod installing hole below solid welding rib is arranged; Be provided with wedge rod installing hole a pair of and rod installing hole axis parallel in the bottom of support body, the wedge rod that has the angle of wedge places in it and in the support body solid welding; Be provided with elastomeric pad, rigid gasket from bottom to top in the support body cavity on the wedge rod.
