Background technology
Electrification railway contact net refers to that downline overhead sets up, and to the special shape transmission line of electricity of electric locomotive power supply, to the contact wire of electric locomotive power supply with bear contact system weight and have the catenary of certain ability to transmit electricity, is the important component part of contact system.Under any climatic conditions, built on stilts adjusting lever, the contact wire state in tensioning all the time, to ensure the normal work of contact net for power supplying, but because variation of ambient temperature produces the phenomenon of expanding with heat and contract with cold, can make contact line conducting wire have length variations, therefore in existing contact system power supply technique, adopt the tension compensating mechanism can compensating contact net conductor length changing.The contact line conducting wire supplementary device that China adopts is at present generally falling mound formula compensating device.Its volume is large, and installation is adjusted loaded down with trivial details, not attractive in appearance, in strong wind, easily swings, and maintenance management expense is high, uses inconvenient.There is again the contact system spring tensioner of online use there is no permanent tension compensating function, job insecurity, compensation precision is low, and result of use is poor.Above existing product can not meet Modern High-Speed electrified railway compensating distance, the large requirement of compensation pulling force.
Summary of the invention
The utility model provides a kind of constant tension compensation device for electrified railway contact network, low to solve the compensation precision proposing in above-mentioned background technology, the problem that result of use is poor.
The technical matters that the utility model solves realizes by the following technical solutions: the utility model provides a kind of constant tension compensation device for electrified railway contact network, it is characterized in that: comprise H steel column, wire drag-line, steel rope, wire tensioning wheel, permanent straining pulley, broken wire protecting equipment, spring tensioner A, spring tensioner B, top one side of described H steel column is provided with firm banking by screw, described firm banking is provided with fixed supported slab, described wire tensioning wheel, permanent straining pulley is arranged on described fixed supported slab by concentric shafts, the radius of described wire tensioning wheel is less than the radius of described permanent straining pulley, described broken wire protecting equipment is fixed on the middle part of described H steel column, described spring tensioner B is fixed on the fixed orifice of described H steel column bottom, described spring tensioner A be hinged on described spring tensioner B above, the upper end of described spring tensioner A is provided with adjusting lever, one end of described wire drag-line connects the contact line conducting wire other end and is connected with described wire tensioning wheel, one end of described steel rope is connected with described permanent straining pulley, the other end is connected with described broken wire protecting equipment through described adjusting lever.
Described spring tensioner A, spring tensioner B are cylindrical spring compensator.
Described spring tensioner B is positioned at the vertical below of spring tensioner A, connects with described spring tensioner A.
The beneficial effects of the utility model are:
1 adopts the spring compensator of cylindrical stage clip, can ensure that the pulling force of exporting is effective lastingly, and balancing force is large, can reach 20KN and with upper pulling force.
2 adopt two or more compensator series connection to use, and complementary range is long, can reach 1.3 meters and above length.
3 adopt permanent tension force conversioning wheel, and by changing force position radius on permanent straining pulley, to make to act on constant tension on contact line conducting wire constant.
4 adopt broken wire protecting equipment, can be in the time that contact line conducting wire break because of accident, carry out broken string braking protection.
5 other the utility model simple structures, install and implement conveniently, stable and reliable for performance, use applicable to subway, light rail and railway tunnel.
