Description
The utility model relates to the device that a kind of special transmission line of electricity to the electric locomotive power supply that is installed on the electric railway provides tension force, refers to a kind of permanent tension force dish spring compensating device especially.
Since the own electric railway, the tension compensating of contact nets in electrified railways (comprising urban light rail railway and subway) is realized by the bob thallium compensating device that comprises assembly pulley, restriction frame and bob thallium composition.Weighing down thallium has cement bob thallium and iron to weigh down two kinds of thalliums, every heavy 25Kg, the compensation of every place needs about 20 approximately, though this device has simply, reliable, compensating length reaches advantages of cheap price greatly, but also exist not attractive in appearance, compensation effect is subjected to weather effect bigger, the broken string braking is difficult for realizing, weighing down thallium lands easily, shortcomings such as it is bigger that the compensation rope ruptures easily and institute takes up space, when particularly carrying out electrification innovation in existing railway tunnel, this device is installed needs tunneling, construction costs height so not only, thus and need closed-loop influence driving inevitably.So the later-model compensator of development is all being inquired in countries in the world for a long time, wherein Britain, Japan, France and the former Soviet Union, all developed and had the compensator of characteristic separately, especially the common line of releasing Japanese DENGYO electric industry Co., Ltd. in November, 1992 with and the Shinkansen with two kinds of compensators, represented the level of current each electric railway advanced technology country; The compensator of Britain's development mainly contains oil, draught head type and electromechanical type, these two kinds of compensator range of uses little (need provide the energy or can makeup oil and unreactable gas), complex structure, the cost height is unsuitable for China's national situation, the compensator of former Soviet Union's development is the constant force compensator that one group of special disk spring is in series with relevant framing member, because the load of this spring only is the 34-40% of common disk spring, the little (f of available deformation range of while
B=0.25h), select for use dish reed number many especially, so not only performance is general for this compensator, and price is very expensive, the compensator that Japan and Germany release, perhaps very heavy (the Shinkansen with the about 500mm of compensator diameter, heavily about 1 ton), perhaps compensating length is little and compensate tension force non-constant (compensation rate is for No. 10 172.5mm, No. 12 is 187.5mm, No. 15 is 175mm, and No. 20 is 162.2mm, and the tension variation rate is in 15%).China develops in this tunnel, together thin line segment man mountain range about 1989 and has adopted the spring tension compensator, and its compensation rate also is no more than 200mm.
The purpose of this utility model provides a kind of safe and reliable, and the reduction accident rate is saved construction costs, and volume is little, and is in light weight, reduces the electric railway permanent tension force disc spring compensator of contact system of the non-bob thallium formula of driving interference.
For this reason, the utility model is taked following technical scheme: it is made up of dished spring assembly A, driver train B, transformation ratio mechanism C, the end of above-mentioned dished spring assembly A links to each other with electric railway one heel post, its other end is connected with driver train, the driver train other end then links to each other with transformation ratio mechanism, and the sliding rope on the transformation ratio mechanism assembly pulley is connected with contact nets in electrified railways.Above-mentioned dished spring assembly comprises cylindrical outer casing 6 and is positioned at the dish spring guidance supporting rack 1 of shell 6, dish spring pressing plate 3, dish spring 5, pilot bar 15, center pull rod 20 and load-shedding equipment, wherein load-shedding equipment comprises secondary pressing plate 4 and off-load adjustable bolt 2, end in the shell 6 is equipped with dish spring guidance supporting rack 1, dish spring pressing plate 3 and secondary pressing plate 4, pilot bar 15 is positioned at a side vertically, the one end passes dish spring pressing plate 3 and is fixed on the dish spring guidance supporting rack 1, the other end stretches in the driver train shell after passing shell 6, and that an end of center pull rod 20 passes secondary pressing plate 4 is fixing with dish spring pressing plate 3, pull bar 7 joins in the other end and the driver train, off-load adjustable bolt 2 ends are passed dish spring pressing plate 3 middle parts and are linked to each other with secondary pressing plate one side, secondary pressing plate 4 opposite sides join with dish spring 5 one ends again, and dish spring 5 other ends are connected to shell 6 other ends.Above-mentioned actuating device is by shell 11 and be positioned at its two arm-ties 14, two turret mounts 16, pull bar 7, compensation linkage 12, guide rod 13, compensation guide rods 21 are formed, two arm-tie 14 symmetries be positioned at shell 11 both sides, two turret mounts 16 intersect symmetry between two arm-ties 14, each turret mount 16 lower end flexibly connects by connecting shaft and corresponding arm-tie 14 lower ends, its upper end then is movably connected by connecting shaft and compensation linkage 12, and the assembly pulley that the longitudinal axis of compensation linkage 12 passes shell 12 and above-mentioned changeable mechanism joins.
Its working process is as described below:
The utility model is screwed into the end with the off-load adjustable bolt 2 in the load-shedding equipment when assembling, this moment, the dish spring of secondary pressing plate 4 generations gave tight power, satisfied the output requirement of compensator standard tension force.When compensation linkage 12 is subjected to contact system when being subjected to tension force that force direction pulls out by transformation ratio mechanism C, turnplate 16 is rotated, drive arm-ties 14 by arm-tie axle 17, drive pull bars 7 by arm-tie 14 again, make dish spring pressing plate 3 compact disc springs 5 and storing energy.When contact system tension force during less than standard tension force, dish spring 5 releases energy and oppositely drives secondary pressing plate 4, pull bar 7, arm-tie 14, make turnplate 16 backward rotation compressing compensation linkage 12, and with transformation ratio mechanism C that compensation linkage 12 links to each other in assembly pulley, then the ratio with 1:4 compensates tension force to contact system, makes it reach standard tension force.And load-shedding equipment gives tight power and makes power output reduce 15% by changing dished spring assembly.
In a word, the utility model adopts the dished spring assembly energy storage, and driver train adopts variable force arm bar principle to change disk spring into constant force according to the power that certain characteristic curve constantly changes; Transformation ratio mechanism adopts the wound form assembly pulley elongation of compensator to be amplified to the compensating length of contact system needs with the ratio of 1:4; Load-shedding equipment in the dished spring assembly then can change the tight power of giving of dished spring assembly, thereby makes power output reduce 15%.
