Abstract
The utility model relates to a high-damping rigid suspension catenary, which belongs to the equipment for power supply of track traffic, and mainly adopts a high-damping annular paraboloid shock absorber (9) to hang an aluminum alloy bus (2) which clamps a copper contacting wire (1) through a screw rod (10). The electrified bus (2) is separated from a crossbeam (7) through an insulation jacket (8) which is made of insulation materials, a fixed screw (6) and a cover (11). A complete high-damping rigid suspension catenary is formed through a drop hanger, middle connectors, rigid-flexible transitional sections, segmental insulators and the like. The high-damping rigid suspension catenary is safe and reliable. In the relative movement of a pantograph and the catenary, no resonance exists, the abrasion is small, and the current transmission quality is high.
Description
Technical field
The utility model relates to a kind of big damping rigid suspension catenary, belongs to the equipment of track traffic power supply usefulness.
Background technology
Before the utility model is made, in prior art, the rigid suspension catenary of track traffics such as subterranean railway, for example: the rigid suspended two-wire contact system device of application number ZL200420122393.5, the perhaps rigid suspended single line contact system of PAC110, all exist eigentone higher, damping is little, and is poor with the dynam matching of pantograph, easily resonance, cause pantograph brush carbon slide plate and copper contact wire quick abrasion, the life-span is short.
The utility model content
The purpose of this utility model is to overcome the little shortcoming of existing rigid suspension catenary damping, and the worn-down rigid suspension catenary that a kind of and pantograph dynam matching performance are good, can reduce copper contact wire and pantograph brush is provided.
The main solution of the utility model is achieved in that
The annular paraboloid bumper 9 that the utility model mainly adopts big damping is through screw rod 10 aluminum alloy " ∏ " the shape bus duct 2 of copper contact wire 1 that hung clamping, insulation sleeve 8, the captive nut of being made by insulating material 6 and cover 11 charged bus duct 2 and crossbeam 7 separated constitutes complete big damping rigid suspension catenary by suspension hook, center coupling, rigid-flexibility transition section, expansion pipe, section insulator etc.
Compared with the prior art the utility model has the following advantages:
1, system's eigentone of big damping rigid suspension catenary reduces, and damping is big, thereby the dynam matching of contact system and pantograph is good.The rigidity of big damping annular paraboloid bumper 9 is non-linear, and system is difficult for resonating, and spark was little when this just made between pantograph brush carbon slide plate and the copper contact wire moving contact, wearing and tearing slowly, the life-span is long.
2, make big damping annular paraboloid bumper 9, insulation sleeve 8, captive nut 6 and cover 11 with insulating material, these insulating materials have replaced the ceramic insulator of using always in the rigid suspension catenary in the prior art, and good insulation preformance is in light weight.
3, big damping annular paraboloid bumper 9 is in compressive state all the time, has avoided High molecular material pulling strengrth shortcoming on the low side, and has utilized the high advantage of High molecular material compression strength, the system reliability height.Bumper is in the ageing-resistant insulation sleeve 8, and bumper environment of living in is clean, and the life-span is long.
Description of drawings
Accompanying drawing is the cross-sectional configuration figure of the utility model agent structure in the installation site.
The specific embodiment
The embodiment of following the utility model in conjunction with the accompanying drawings is further described: enforcement of the present utility model, and at first to make aluminum alloy bus duct 2 respectively, pay hook 3, part in addition such as main suspension hook 4, insulation sleeve 8, big damping annular paraboloid bumper 9, screw rod 10.Bus duct 2 is for extruding aluminium section bar, has preferably elasticity in order to the clamping copper contact wire, the required electric current of the common transferring electric power locomotive of bus duct and copper contact wire.Paying hook 3 is the foundry goods of copper or aluminium with main suspension hook 4, is used for hanging bus duct 2.Insulation sleeve 8, the captive nut made from insulating material 6 and cover 11 in order to replace ceramic insulator, safeguarded insulativity between copper contact wire 1 and bus duct 2 and the crossbeam.Big damping annular paraboloid bumper 9 forms through molded vulcanization with butyl rubber, and also available centrifugal casting polyurethane elastomer forms.The existing high insulating power of these two kinds of materials have high viscoelastic damping again, and the zero dimension damping ratio C/Cc that can make system increases to 0.27 even 0.40 from 0.05, and the resonance magnification factor of system drops to 1.6 from 10.Eigentone differs more than 1.414 times and just can not resonate between rigid suspension catenary and the pantograph.Bumper 9 is rings, the intrinsic curve of its section is a parabola, the buffer of damper performance of this shape is apparently higher than the bumper of other shapes, especially enter the moment of rigid suspension catenary from the flexible suspension contact system in pantograph, can obviously reduce the impact of pantograph to rigid suspension catenary, electro spark obviously reduces, adopt rigid suspension catenary in the same circuit urban tunnel of the subway in a lot of cities of China, the flexible suspension contact system is adopted on ground, suburb, adopts the utility model just can overcome the king-sized defect of electro spark of rigid-flexibility transition section.
The utility model assembling process after being ready to all parts is as follows: at first the 2 sagging girder steels of reserved steel bar weldering from subway tunnel top concrete structure hang crossbeam 7, in crossbeam 7 medium pores, place insulation sleeve 8, insulation sleeve 8 is fastened on the crossbeam 7 with captive nut 6.Pierce into screw rod 10 after in insulation sleeve 8, earlier placing bumper 9, utilize screw thread to screw on to cover 11 and amplitude limit nut 5.With double nuts main suspension hook 4 is fixed on the bottom of screw rod 10, closes after hanging over bus duct 2 on the main suspension hook 4 and pay a hook 3, and fuse 3 and 4 with bolt.Utilize again and dolly is installed, finish installation sharp corner in the middle of copper contact wire 1 embedding bus duct 2 bottoms.Generally speaking, the gap between amplitude limit nut 5 upper ends and insulation sleeve 8 bottoms should be equal to or greater than the gap between screw rod 10 tops and the lid 11.
Connector in the middle of the utility model adds between bus duct 2, rigid-flexibility transition section, expansion pipe, anchor, section insulator etc., just constituted complete big damping rigid suspension catenary, traction power supply station DC1500V direct current (DC) is connected on the bus duct 2 with power feeder, and electric locomotive just can constantly obtain electric current from big damping rigid suspension catenary by on the go by pantograph.
