Background technology
The bracket generally applied in electrified railway at present or registration arm bracing or strutting arrangement are primarily of strut bar clamp and strut bar composition.
Strut bar clamp is semicircle 3 pore structure that two panels is identical, needs to fix with pipe and supporting single lug when two panels clamp is installed simultaneously, and the deficiency of existence is: when mounted owing to using 3 cover bolt pairs to connect, increase the probability that gets loose of bolt pair, reduce anti-loosening property; Bolt pair number of parts is more, and cost increases; Install also inconvenient;
Strut bar is support tube two ends welding monaural structure, and this structure Problems existing is:
(1) there is welding process risk in welded structure, namely because weld defect causes the deficiency of structural strength;
(2) after support tube welds with two ends monaural, in order to rear road hot dip galvanizing process, must open 2 and leak zinc hole on support tube, so just in existence pipe, galvanizing flux is not easily poured out, zinc coating is uneven, thickness is difficult to ensure card, and leakage zinc hole must install the deficiencies such as blocking cover again, thus reduce antiseptic property;
(3) there is the more deficiency of complex process, part in this structure.
Utility model content
The purpose of this utility model overcomes above shortcomings on existing bracket or registration arm support device structure, proposes a kind of safe reliability high, and electrification contact network cantilever support and the registration arm of convenient installation support.
For this reason, the utility model provides a kind of bracket and registration arm bracing or strutting arrangement, comprise strut bar and the strut bar clamp being connected to strut bar two ends, strut bar two ends are provided with the fixed orifice for connecting strut bar clamp, described strut bar clamp is semicircle double-pore structure, be made up of two semi-round clips, the two ends of clip are respectively equipped with a bolt hole, two semi-round clips are fastened togather by the bolt hole of same one end of screw bolt passes two clips, outside clip, semicircle arc outer are provided with gusset.
The bolt hole outer at described clip two ends is provided with bolt cap anti-rotation groove.
Described strut bar is overall square steel or steel-tube construction, and strut bar two ends are through with fixed orifice respectively.
Described strut bar is rectangular steel tube or round steel pipe, and the two ends of strut bar adopt hot-pressed mode to be squeezed into monaural, and monaural is provided with fixed orifice.
Described strut bar is solid square steel, and the two ends of strut bar are drilled with through fixed orifice respectively.
The beneficial effects of the utility model: this bracket that the utility model provides and registration arm bracing or strutting arrangement, compared with prior art, have the following advantages:
One, because the connection of strut bar clamp and strut bar and pipe adopts two bolt pair, avoids the increase of the probability that gets loose that more bolt pair quantity causes, thus improves the anti-loosening property of tie bolt pair, and reduce costs.
Its two, strut bar adopts square steel or steel pipe two ends to arrange fixation hole configurations, can reduce number of parts, Simplified flowsheet, raising temperature zinc quality, thus improves antiseptic property.
Its three, strut bar clamp is arranged bolt cap anti-rotation groove, spline effect can be played, more convenient during installation, and improve anti-loosening property.
Its four, strut bar clamp arranges outstanding rib, can intensity be improved, reduce costs.
Below with reference to accompanying drawing, the utility model is described in further details.

Detailed description of the invention
Embodiment 1:
The present embodiment provides a kind of bracket and registration arm bracing or strutting arrangement, as shown in Figure 1, comprise strut bar 2 and the strut bar clamp 1 being connected to strut bar 2 two ends, strut bar 2 two ends are provided with the fixed orifice 3 for connecting strut bar clamp 1, composition graphs 2 and Fig. 3, strut bar clamp 1 is semicircle double-pore structure, be made up of two semi-round clips 4, the two ends of clip 4 are respectively equipped with a bolt hole, two semi-round clips 4 are fastened togather by the bolt hole of same one end of screw bolt passes two clips 4, outside clip 4, semicircle arc outer are provided with gusset 5.
Two clips 4 are combined, one end is fixed up by bolt passing through bolt hole, at the other end, one end of strut bar 2 clamps by two clips 4, then uses the bolt hole of clip 4 above screw bolt passes and the fixed orifice 3 of strut bar 2, then passes the bolt hole of below clip 4, so just, the connection of strut bar clamp 1 and strut bar 2 can be realized, by the circular opening that bracket or registration arm form through two clips 4, then by fixing for bolt tight, just can realize the firm support of bracket or registration arm.
Outside clip 4, semicircle arc outer is provided with gusset 5, gusset 5 can make semi-round clip 4 firmer, and structure overall like this will be more stable.
Embodiment 2:
On the basis of embodiment 1, in the present embodiment, the bolt hole outer at clip 4 two ends is provided with bolt cap anti-rotation groove 6, after total is fixing with bolt, bolt cap is finally stayed in bolt cap anti-rotation groove 6, such bolt cap just can not arbitrarily rotate, play spline effect, improve anti-loosening property.
In the present embodiment, strut bar 2 is overall square steel or steel-tube construction, and strut bar 2 two ends are through with fixed orifice 3 respectively.
The supporting single lug of traditional support bar is fixed together with support tube by crimping or welding process, and wherein supporting single lug adopts the manufacture of metal paattern forging process, and technique is loaded down with trivial details; Easily there is incomplete fusion, lack of penetration, the mass defect such as pore, slag inclusion in components welding technique.The strut bar 2 of the present embodiment adopts square steel or steel pipe two ends to arrange fixed orifice 3 structure, need not carry out crimping or welding, number of parts, Simplified flowsheet can be reduced, and there is not enclosure space in this tubular structure, do not need to process deflation hole, simplify manufacturing procedure, it also avoid acid solution in pot galvanize acid cleaning process and remain, Corrosion Protection also improves further.
Embodiment 3:
Strut bar 2 in embodiment 2 can be solid square steel, and the two ends of strut bar 2 are drilled with through fixed orifice 3 respectively.
Strut bar 2 also can be rectangular steel tube or round steel pipe, and as shown in Figure 4, the two ends of strut bar 2 adopt hot-pressed mode to be squeezed into monaural 7, monaural 7 are provided with fixed orifice 3.
Traditional support bar will to begin to rehearse pore to support tube when zinc-plated, during pickling, acid solution can remain in pipe, cause internal corrosion, cause running hidden danger, there is not enclosure space in tubular structure, does not need to process deflation hole, simplifies manufacturing procedure, it also avoid acid solution in pot galvanize acid cleaning process to remain, Corrosion Protection also improves further.
More than exemplifying is only to casehistory of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
