Abstract
The fixed pin shaft that the utility model discloses a kind of U-shaped link, comprise U-shaped ring body, be configured in the screw bolt and nut on described U-shaped ring body and be arranged on described bolt, described U-shaped ring body is adopt 35GrMo structural alloy steel to forge the U-shaped ring body processed.Compared with the U-shaped link made with existing employing 45 steel or 40Gr material, the U-shaped ring body of U-shaped link of the present utility model adopts the forging of high, the low temperature resistant brittle failure performance of intensity good 35MrMo structural alloy steel to process, its tensile strength reaches 980MPa, and can 12 be reached at-35 DEG C of elongation, cryogenic property is far superior to 45 steel or 40Gr, so just efficiently solve U-shaped link used for transmission line and occur cold short disconnected problem, ensure that the safe operation of circuit, there are very wide market prospects.
Description
Technical field
The utility model relates to transmission line hardware, particularly relates to a kind of U-shaped link.
Background technology
Domestic U-shaped link used for transmission line mostly adopts 45 steel or the forging of 40Gr material to process, although these two kinds of steel intensity are high, after forging, fragility is but very large, when using at low ambient temperatures, often there will be cold short disconnected phenomenon.Because China's microthermal climate in winter area is wide, the U-shaped link as adopted 45 steel or 40Gr material to forge to process can run transmission line and cause very large potential safety hazard.
For this reason, applicant carried out useful exploration and trial, have found result of the above problems, technical scheme described below produces under this background.
Utility model content
Technical problem to be solved in the utility model: use at low ambient temperatures for existing U-shaped link and often occur cold short disconnected phenomenon and run to transmission line the problem of potential safety hazard of causing, now provides a kind of and has high-intensity performance and the strong U-shaped link of anti-low-temperature brittle fracture ability.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of U-shaped link, the fixed pin shaft comprising U-shaped ring body, be configured in the screw bolt and nut on described U-shaped ring body and be arranged on described bolt, is characterized in that, described U-shaped ring body is adopt 35GrMo structural alloy steel to forge the U-shaped ring body processed.
Compared with the U-shaped link made with existing employing 45 steel or 40Gr material, the U-shaped ring body of U-shaped link of the present utility model adopts the forging of high, the low temperature resistant brittle failure performance of intensity good 35MrMo structural alloy steel to process, its tensile strength reaches 980MPa, and can 12 be reached at-35 DEG C of elongation, cryogenic property is far superior to 45 steel or 40Gr, so just efficiently solve U-shaped link used for transmission line and occur cold short disconnected problem, ensure that the safe operation of circuit, there are very wide market prospects.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Be a kind of U-shaped link see what provide in Fig. 1 and Fig. 2, figure, comprise U-shaped ring body 100, bolt 200, nut 300 and fixed pin shaft 400.U-shaped ring body 100 adopts the good 35MrMo structural alloy steel of high, the low temperature resistant brittle failure performance of intensity to forge and processes, its tensile strength reaches 980MPa, and can 12 be reached at-35 DEG C of elongation, cryogenic property is far superior to 45 steel or 40Gr, so just efficiently solve U-shaped link used for transmission line and occur cold short disconnected problem, ensure that the safe operation of circuit.Certainly, bolt 200, nut 300 and fixed pin shaft 400 also adopt the good 35MrMo material of high, the low temperature resistant brittle failure performance of intensity to make, and improve its tensile strength and low temperature resistant fragility energy.
U-shaped ring body 100 is made up of U-shaped ring main body 110 and a pair circular connection section 120a, 120b.A pair circular connection section 120a, 120b are symmetricly set on two vertical edge ends of U-shaped ring main body 110, and one-body molded with U-shaped ring main body 110.In order to avoid the junction between a pair circular connection section 120a, 120b and two vertical edge ends of U-shaped ring main body 110 forms concentrated stress, be connected through ffp filter between a pair circular connection section 120a, 120b and two vertical edge ends of U-shaped ring main body 110.A pair circular connection section 120a, 120b offer a hole respectively.
The threaded shank 210 of bolt 200 is each passed through the hole on a pair circular connection section 120a, 120b and passes the hole of circular connection section 120b, and nut 300 revolves the threaded shank 210 being located at bolt 200 and passes in the part in the hole of circular connection section 120b.A pin-and-hole is offered away from one end radial direction of bolt head 220 in the threaded shank 210 of bolt 200.Fixed pin shaft 400 is arranged in the pin-and-hole of threaded shank 210 of bolt 200.
In addition, the surface of U-shaped ring body 100, bolt 200 and nut 300 plates one deck zinc after hot galvanizing process, strengthens the mechanical strength of U-shaped link.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
