Abstract
The utility model belongs to the technical field of telescoping devices and discloses a modulus-type profile steel telescoping device. The modulus-type profile steel telescoping device is mainly characterized by comprising two edge beams, wherein a plurality of middle beams are arranged between the two edge beams; rubber sealing strips are arranged between the edge beams and the middle beams and between the middle beam and the middle beam; the edge beams are fixedly connected with a supporting box; the middle beams are fixedly connected with a hanging bracket; the hanging bracket and the supporting box which are coaxial are connected through a pressing support, a bearing support and a supporting cross beam; the hanging bracket is an integrally-forged square frame; and the supporting cross beam is I-shaped forging steel. According to the modulus-type profile steel retracting device, the hanging bracket is the integrally-forged square frame; and compared with the hanging bracket welded by steel plates, a metallographic structure is dense, the bearing capability is high and the stress concentration is avoided. The supporting cross beam is the I-shaped forging steel and the metallographic structure is dense, so that the contact area among the supporting cross beam, the bearing support and the pressing support is enlarged, the stressing state of the bearing support and the pressing support is improved, and the service lives of the bearing support and the pressing support are prolonged.
Description
Technical field
the utility model belongs to the stretching device technical field, relates in particular to a kind of modulus formula shaped steel stretching device.
Background technology
modulus formula shaped steel stretching device comprises two side bars; Be provided with many central sills between two side bars; Between side bar and the central sill, be provided with rubber seal tape between central sill and the central sill; Side bar and supported box are connected, and central sill and suspension bracket are connected, the suspension bracket of coaxial line and supported box through compress supporting, the pressure-bearing supporting is connected with bearing cross beam.The suspension bracket of current use adopts the steel plate welding to form more, because weld defect and stress are concentrated, makes bearing capacity be affected.Bearing cross beam adopts the bar steel more, and the contact area that supports and compress supporting with pressure-bearing is less, influences the stress that pressure-bearing supported and compressed supporting.Load-carrying members are fragile and lost efficacy, thereby cause central sill fracture and whole destruction of stretching device.
The utility model content
The technical problem that
the utility model will solve just provides a kind of long service life; Adapt to various displacements; Can car load be passed to the beam body reliably, stretching device respectively stitches wide modulus formula shaped steel stretching device even, easy to replace and maintain.
for solving the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise two side bars, be provided with many central sills between two side bars; Between side bar and the central sill, be provided with rubber seal tape between central sill and the central sill; Side bar and supported box are connected, and central sill and suspension bracket are connected, the suspension bracket of coaxial line and supported box through compress supporting, the pressure-bearing supporting is connected with bearing cross beam; Described suspension bracket is that one is forged square frame, and bearing cross beam is the I shape forged steel.
its additional technical feature is: between described side bar and the central sill, be provided with polyurethane spring between central sill and the central sill.
a kind of modulus formula shaped steel stretching device that the utility model provided, compared with prior art, suspension bracket is that one is forged square frame, compares with the suspension bracket that adopts the steel plate welding, and metallographic structure is fine and close, and bearing capacity is high, has avoided stress to concentrate.Bearing cross beam is the I shape forged steel, and metallographic structure is fine and close, has increased the supporting of bearing cross beam and pressure-bearing and has compressed the contact area of supporting, improved the pressure-bearing supporting and compressed the stress of supporting, has prolonged the life-span that pressure-bearing supported and compressed supporting.And between side bar and the central sill, be provided with polyurethane spring between central sill and the central sill, make that each seam seam is wide evenly, and adapt to various displacements, can car load be passed to the beam body reliably.
Description of drawings
Fig. 1 is the structural representation of a kind of modulus formula of the utility model shaped steel stretching device;
Fig. 2 is the cross-sectional view of modulus formula shaped steel stretching device;
Fig. 3 is the structural representation of central sill and suspension bracket.
The specific embodiment
further specify below in conjunction with the structure of accompanying drawing to a kind of modulus formula shaped steel stretching device that the utility model provided.
are as shown in Figure 1; A kind of modulus formula of the utility model shaped steel stretching device comprises two side bars 1,2; Two side bars 1, be provided with many central sills 3 between 2, between side bar 1,2 and the central sill 3, be provided with polyurethane spring 4 between central sill 3 and the central sill 3.As shown in Figure 2, between side bar 1,2 and the central sill 3, be provided with rubber seal tape 5 between central sill 3 and the central sill 3, side bar 1,2 and supported box 6 are connected, and central sill 3 is connected with suspension bracket 7.As shown in Figure 3, central sill 3 is connected with suspension bracket 7, and suspension bracket 7 is connected with the supported box of coaxial line with bearing cross beam 10 through compressing supporting 8, pressure-bearing supporting 9, and suspension bracket 7 is an one forging square frame, and bearing cross beam 10 is the I shape forged steel.
a kind of modulus formula shaped steel stretching device that the utility model provided, suspension bracket 7 forges square frame for one, compares with the suspension bracket that adopts the steel plate welding, and metallographic structure is fine and close, and bearing capacity is high, has avoided stress to concentrate.Bearing cross beam 10 is the I shape forged steel; Metallographic structure is fine and close; Increase bearing cross beam 10 and pressure-bearing supporting 9 and the contact area that compresses supporting 10, improved pressure-bearing supporting 9 and compressed and supported 10 stress, prolonged pressure-bearing supporting 9 and the life-span that compresses supporting 10.And between side bar 1,2 and the central sill 3, be provided with polyurethane spring 4 between central sill 3 and the central sill 3, make that each seam seam is wide evenly, and adapt to various displacements, can car load be passed to the beam body reliably.
a kind of modulus formula shaped steel stretching device that the utility model provided is not limited only to said structure; But no matter be which kind of form; Forge square frame so long as suspension bracket is an one, bearing cross beam is the I shape forged steel, all falls into the utility model protection domain.
