Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The present embodiment is taking splicing sleeve protective device as example, and as shown in Figures 3 to 6, the splicing sleeve protective device that the embodiment of the present invention provides comprises: sleeve pipe 5, transition rings 6, loose collar 7, rubber sleeve 8, screw 9.First, at two semicircle steel pipe two ends of sleeve pipe 5 semi-circular member of welding transition ring 6 respectively, connect the semi-circular member of loose collar 7 at the semi-circular member end of transition rings 6, then two semi-circular members of two semi-circular members of two semicircle steel pipes of sleeve pipe 5, transition rings 6 and loose collar 7 are connected by screw respectively fixing.
One end outer wall that transition rings 6 is connected with loose collar 7 has round ring boss, the inwall of loose collar 7 one end has the toroidal cavity matching, the outer wall of the other end has the boss identical with it, being joined end to end and being formed snakelike loose collar group by 2～6 loose collars 7 in sleeve pipe 5 one end; Because the width of groove is greater than the width of boss, make between transition rings 6 and loose collar 7, there is space between loose collar 7 and loose collar 7, snakelike loose collar group can rotoflector in the time being subject to external force; The radius of curvature R of snakelike loose collar group is 12d～20d, and wherein d is the diameter of wire 1; The setting range of the envelope angle α that snakelike loose collar group forms is 15 °～30 °.
Splicing sleeve 3 is arranged in sleeve pipe 5 inner chambers of splicing sleeve protective device 2, and after wire 1 continues by splicing sleeve 3, its two ends are respectively through transition rings 6 and loose collar 7; Between the inwall of transition rings 6 and loose collar 7 and wire 1, be provided with rubber sleeve 8, the end of rubber sleeve 8 is provided with the projection that is positioned at loose collar 7 outsides, can avoid the inwall of wire 1 and transition rings 6 and loose collar 7, and wire 1 is impaired with the end friction of loose collar 7; As shown in Figure 1 to Figure 2, in the time that tension stringing was constructed pulley 4, the stressed bending of snakelike loose collar group that loose collar 7 forms, wire 1 is also thereupon bending, has avoided wire 1 due to the concentrated and impaired situation of stress; When sleeve pipe 5 is in the time crossing pulley 4, because sleeve pipe 5 adopts the intensity that steel pipe tool is higher, avoid the stressed bending of aluminum splicing sleeve 3 that intensity is lower; The effect of this device in the time that large-section lead tension stringing is constructed is particularly remarkable.
Wherein, the material of preparing sleeve pipe 5, transition rings 6 and loose collar 7 is by weight percentage, C≤0.22%, Mn:1.50～1.70%, Si≤0.65%, P≤0.045%, S≤0.055%, V:0.05～0.25%, Nb:0.035～0.055%, Ti:0.05～0.25%, Cr :≤0.50%, Ni :≤0.80%, surplus is iron.
The material of preparing sleeve pipe 5, transition rings 6 and loose collar 7 in the present embodiment is by weight percentage, C:0.19%, Mn:1.67%, Si:0.43%, P:0.039%, S:0.044%, V:0.07%, Nb:0.051%, Ti:0.17%, Cr:0.31%, Ni:0.67%, iron is surplus.By adopting said ratio, make the intensity of whole device improve 5%, also extended 10 years useful life; Reach the effect of better protection splicing sleeve.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although the present invention is had been described in detail with reference to above-described embodiment, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present invention, and do not depart from any amendment of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of claim scope of the present invention.
