Description
Technical field
The utility model belongs to railway power supply apparatus field more particularly to a kind of railway contact line dropper.
Background technique
Currently, contact net generally uses dropper, its advantage is that according to its prefabricated length of live exact computation results, pole
The big adjusting operation for reducing dropper.But it is uneven etc. all in actual operation, to be stretched due to carrier cable, contact line by temperature
It is multifactor, cause the phenomenon of dropper relaxation to happen occasionally.
Meanwhile the length adjustment of dropper needs to adjust at dropper Horizontal messenger wire clamp in maintenance repair, and maintenance repair
In, tower wagon or railcar operation mode are taken in operation, are limited by height of contact wire, and maintenance personal stands in tower wagon or railcar operation
On platform, dropper Horizontal messenger wire clamp can not be highly got at, therefore most maintenance personal need to step down in contact line and be adjusted to it.
Since maintenance personal steps down in the gravity of contact line, dropper length is caused not to be adjusted in place once, after needing adjustment, under arrive
Workbench after whether measurement height of contact wire meets, then is adjusted up, repeatedly, this work is caused to take a long time
And precision is inadequate.
Summary of the invention
This practical purpose is to provide a kind of railway contact line dropper, which can quickly adjust length,
Easy access personnel's inspection operation improves overhaul efficiency.
To achieve the above object, the technical solution of the utility model is: a kind of railway contact line dropper, including two
Dropper adjusts bolt,
The dropper, including dropper rope, Messenger wire hanging string clamp, cardioid ring, the cardioid ring are lifted on carrier cable dropper
Lower part is pressed from both sides, dropper rope top is wound on cardioid ring, and dropper rope is fixed at the lower end folding of cardioid ring by cable clip bolt, dropper rope
Upper end is provided with connecting terminal, and connecting terminal is connect with Messenger wire hanging string clamp, and dropper rope lower end is that an annulus is buckled,
The adjusting bolt is provided with the cannulated sleeve of opposite threads, the setting installation of cannulated sleeve both ends for a both ends
There is bolt, hinged one of bolt outer end setting is U-shaped to buckle, it is provided with scale in the middle part of the cannulated sleeve,
The U-shaped deduction of points is not connect with the annulus button of a dropper.
Adjustment bolt is identical as dropper rope material.
The adjustment length of adjustment bolt is 0~15CM.
The length of railway contact line dropper described in the utility model is full-length.
The utility model structure is simple, easy to use, can quickly adjust dropper length, service personnel in climbing without arriving
Be adjusted in contact line, when adjustment, service personnel can directly observe adjustment situation, avoided it is previous blindly adjust, need
The low problem of amendment bring working efficiency repeatedly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the adjusting bolt schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, 2, a kind of railway contact line dropper, including two droppers 1 adjust bolt 2,
Dropper, including dropper rope 11, Messenger wire hanging string clamp 12, cardioid ring 13, cardioid ring 13 are lifted on carrier cable dropper
Lower part is pressed from both sides, dropper rope top is wound on cardioid ring 13, and dropper rope is fixed by cable clip bolt 14 at the lower end folding of cardioid ring, is hung
String rope upper end is provided with connecting terminal 15, and connecting terminal 15 is connect with Messenger wire hanging string clamp 12, and 11 lower end of dropper rope is one
A annulus button 16,
Bolt 2 is adjusted, the cannulated sleeve 21 of opposite threads, the setting installation of 21 both ends of cannulated sleeve are provided with for a both ends
There is bolt 22, hinged one of 22 outer end of bolt setting is U-shaped to buckle 23, it is provided with scale in the middle part of cannulated sleeve,
The U-shaped button 23 is connect with the annulus button 16 of a dropper respectively.
Adjustment bolt is identical as dropper rope material.
The adjustment length of adjustment bolt is 0~15CM.
In use, the utility model is as traditional dropper mounting means, after installation after a period of time due to carrier cable, connect
Line is touched after by the flexible unevenly equal factors generation dropper relaxation of temperature, when service personnel passes through tower wagon or railcar operation,
The adjustment to relaxation dropper can be completed by rotation adjusting bolt.
