Description
Technical field
The utility model relates to electrification railway contact net attachment technique field used.
Background technology
Cantilever support used on electrification contact networks of rapid transit railway or registration arm support and are mainly used in being connected with the reinforcement between oblique wrist and arm or between oblique wrist and arm with registration arm flat at present, the supporting construction generally applied is the two ends adopting welding process two supporting single lugs to be welded in respectively support tube body, so just define enclosure space in support inside, when pot galvanize, gas generation heat expansion effect in enclosure space, can cause interior application force to support itself.Also have owing to adopting welding process, cannot do during welding 100% perfect welding, micro gap or hole is there is between the support tube body that minority supports and supporting single lug, during acid cleaning process before zinc-plated, pickle can enter along these micro gaps or hole and support inside, and when hot dip galvanizing process, galvanizing flux also can enter along these micro gaps or hole and support inside, at high temperature can there is vigorous reaction in two kinds of liquid, causes the generation of explosion accident.
After the manufacturing process of supporting single lug generally adopts forging and molding, monaural afterbody adopts machined into processes to go out afterbody cylinder and bevel for welding, facilitates supporting single lug to fill in support tube body interior and carry out shutoff welding after turning.Because the manufacturing process of supporting single lug is comparatively complicated, so seek more convenient, that quality the is more stable manufacturing process of a kind of making to become inexorable trend.
Utility model content
Technical problem to be solved in the utility model is to provide the electrification railway contact net that a kind of structure is simple, manufacture craft is simple, easy for installation and supports, and can be used as cantilever support or registration arm support.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of electrification railway contact net supports, comprise the supporting single lug at support tube body and two ends, described support tube body and supporting single lug are welded and fixed, described supporting single lug comprises ring-type platform circle, false boss and connection monaural, the fixed orifice connected is provided with in the middle part of described connection monaural, described ring-type platform is justified upper and is provided with auxiliary hole in connection monaural bilateral symmetry, is provided with shutoff plug in described auxiliary hole; Described support tube body is tubular body, and described ring-type platform rounded edge is provided with the groove welded with support tube body.
Preferably, described supporting single lug entirety is forging, and the cross section of described false boss is that two ends are protruding, class 8 font of medial recess, and described two auxiliary holes are arranged on the both sides, medial recess place of false boss.
Preferably, described shutoff plug is plastic plug or aluminum pulling rivet.
The beneficial effect adopting technique scheme to produce is: install with other part by the fixed orifice in the middle part of supporting single lug is convenient, its ring-type platform circle arranges auxiliary hole, can facilitate support tube body weld with supporting single lug complete carry out zinc-plated, zinc-plated front and back enter the intrinsic pickle of support tube and galvanizing flux all flows out by auxiliary hole, avoid two kinds of liquid in support tube body, vigorous reaction occur and explode, improve the safety factor of operation, zinc-plated complete after recycling plastic plug or aluminum pulling rivet as shutoff plug, shutoff is carried out to auxiliary hole, supporting single lug just forges groove in ring-type platform rounded edge when forging, facilitate welding of support tube body and supporting single lug, eliminate machined into operation, simplify manufacturing process, in addition, be that two ends are protruding in the false boss cross section of supporting single lug afterbody, class 8 font of medial recess, machined into is not needed just can directly to fill in support tube body interior, and relatively traditional cylinder, both machined into operation had been eliminated, again save material, alleviate weight.The utility model has the advantage that structure is simple, manufacture craft is simple, easy for installation, and the cantilever support of electrification contact networks of rapid transit railway and registration arm support and all can adopt this kind of structure.
