Abstract
The utility model relates to a rail travel plumb -line mechanism in pit, including the upper end fix the screw -thread steel of top of roadway board, with screw -thread steel lower extreme welded angle iron bracket and porcelain plumb -line ware. Angle iron bracket's both ends are provided with the support cantilever respectively, every support cantilever lower extreme be provided with eye bolt and with the eye bolt matched with bolt hole, eye bolt's outer end is passed the bolt hole and is fixed in the outside of support cantilever with the nut, is connected with a plastic envelope wire rope through the steel wire checkpost between the inner of the eye bolt on two support cantilevers, plastic envelope wire rope passes through the wire pull ware and is connected with porcelain plumb -line ware. The utility model discloses install simply, with low costs, can reduce the wearing and tearing between pantograph aluminium bar and the overhead line effectively, the life of extension pantograph aluminium bar and overhead line.
Description
Technical field
The utility model is related to a kind of down-hole rail travel line hanging mechanism.
Background technology
Line hanging mechanism is conventional mechanism in the rail mounted transport system of down-hole, is mainly used in installing electric locomotive stringing.Existing skill
In art, line hanging mechanism is commonly used in down-hole two kinds: one kind is horizontal plumbing method, and this kind of method makes porcelain rope hoister hanging, can reduce by electricity
Bow aluminium bar and the abrasion of stringing, long service life, but complex structure, investment cost is high, and tunnel section is had high demands；Another
It is simple Method for Installation, together with the screw-thread steel welding at tunnel top, porcelain rope hoister is arranged in the waist type groove of channel-section steel channel-section steel, this kind of
Method is installed simply, and expense is low, but porcelain rope hoister is rigid connection, the abrasion between aggravation pantograph aluminium bar and stringing, especially
It is in porcelain rope hoister installation place.
Utility model content
The purpose of this utility model is to provide a kind of down-hole rail travel line hanging mechanism, and structure is simple, can reduce electricity
Abrasion between bow aluminium bar and stringing.
For realizing above technical purpose, the technical solution adopted in the utility model is:
Down-hole rail travel line hanging mechanism it is characterised in that: include upper end and be fixed on screw-thread steel and the screw thread of back
The angle bar frame of steel lower end welding and porcelain rope hoister；
The two ends of described angle bar frame are respectively arranged with support cantilever, each support cantilever lower end be provided with eyelet bolt and
The bolt hole matching with eyelet bolt, the outer end of described eyelet bolt passes through bolt hole and is fixed on support cantilever with nut
Outside, is connected with a plastic packaging steel wire rope by steel wire clamp between the inner of eyelet bolt on two support cantilevers；Described
Plastic packaging steel wire rope is connected with porcelain rope hoister by device of pulling strings.
Described porcelain rope hoister is internally provided with screwed hole, and described screwed hole is used for being fixedly connected with the single lug of stringing；Frame
The distance that line floats is less than the distance between porcelain rope hoister upper surface and angle bar frame lower surface.
More than the length of pantograph aluminium bar the distance between inside described two stands cantilever.
Compared with prior art, the utility model has the advantages that
The utility model fabrication and installation are simple, expense is low, by the fixation of angle bar frame and plastic packaging steel wire rope so that porcelain hangs
Line device and stringing have certain floating space, can efficiently reduce the abrasion between pantograph aluminium bar and stringing, especially in porcelain
Rope hoister installation place, thus extend the service life of pantograph aluminium bar and stringing.
Brief description
Fig. 1 is the overall structure diagram of the utility model embodiment.
Specific embodiment
With reference to the accompanying drawings and examples the utility model is described further.
As shown in figure 1, embodiment of the present utility model includes screw-thread steel 1 and the screw-thread steel 1 that upper end is fixed on back
The angle bar frame 3 of lower end welding and the porcelain rope hoister 2 being connected with angle bar frame 3 by plastic packaging steel wire rope 5.
The two ends of described angle bar frame 3 are respectively arranged with support cantilever 9, and each support cantilever 9 lower end is provided with movable joint spiral shell
Bolt 4 and the bolt hole matching with eyelet bolt 4, the outer end of described eyelet bolt 4 passes through bolt hole and is fixed on nut 8
The outside of frame cantilever 9, is connected with a plastic packaging by steel wire clamp 7 between the inner of eyelet bolt 4 on two support cantilevers 9
Steel wire rope 5.
The distance between described two stands cantilever 9 inner side is more than the length of pantograph aluminium bar.
Described plastic packaging steel wire rope 5 is connected with porcelain rope hoister 2 by device 6 of pulling strings, and described porcelain rope hoister 2 is internally provided with screw thread
Hole, described screwed hole is used for being fixedly connected with the single lug of stringing.Described porcelain rope hoister 2 upper surface and angle bar frame 3 lower surface
The distance between for stringing float ultimate range.
During use, beat square in roadway top board correct position, screw-thread steel 1 be fixed on anchor pole intraocular with cement-roll,
Highly intercept appropriate length according to pantograph, weld angle bar frame 3 in screw-thread steel 1 lower end, and pass through eyelet bolt 4, plastic packaging steel
Cord 5, pull strings device 6 and porcelain rope hoister 2 is fixed on angle bar frame 3 steel wire clamp 7.The utility model structure simple it is easy to
Install, when pantograph aluminium bar is contacted with stringing, stringing has the scope fluctuating, and especially pantograph aluminium bar is through porcelain rope hoister
Installation place when, porcelain rope hoister 2 and stringing all have the scope fluctuating, can effectively reduce pantograph aluminium bar and stringing it
Between abrasion, extend the service life of pantograph aluminium bar and stringing.
