Description
Technical field
The present invention relates to a kind of subway tunnel, particularly a kind of bus-bar joint device of subway tunnel.
Background technology
Along with the fast development that urban rail transit in China is built, the form of rigid suspension catenary is widely adopted.Rigid suspension catenary embeds by contact wire the system that bus duct from beginning to end forms, and it is the visual plant of electrified railway locomotive and rail traffic vehicles power supply, and its quality good or not directly has influence on the operation of locomotive.
In urban subway tunnel construction, all devise Flood gate, run into war and seriously leak extraordinary circumstances time, need Flood gate and the Flood gate in quick closedown tunnel, to guarantee tunnel and personal security.But, under the stop of bus duct, Flood gate cannot thoroughly be closed, need to send special personnel to enter in tunnel, disassembled from whole contact net system by one of Flood gate place section of bus duct, when the situation is critical or water is larger, personnel just cannot enter into tunnel, even if can tunnel be entered, waste time and energy because existing design problem also makes dismounting compare.
In order to address this problem, (application number is: 201110361724.5) a kind of dis-connectable busbar joint device of rigid catenary to find to disclose a kind of dis-connectable busbar joint device of rigid catenary by Chinese patent through retrieval, comprise bus duct A to hold, bus duct B holds and the linkage section be between the two for being connected, it is characterized in that, described bus duct A holds and is connected with the two ends of linkage section respectively by a sliding-type bus-bar joint with bus duct B end, described sliding-type bus-bar joint comprises feeding section support, quiet joint and dynamic joint, described quiet joint is fixed on feeding section support, described dynamic joint is arranged in feeding section support, and can along feeding section bracket slide, above-mentioned dynamic joint is set on the two ends of linkage section respectively, and is formed with linkage section and be slidably connected, and above-mentioned quiet joint is held with bus duct A respectively and bus duct B holds and is connected mutually, dynamic joint is provided with joint can be made to move towards quiet joint and depart from the linkage of linkage section, described linkage section and bus duct A hold or bus duct B hold between be also provided with one and be electrically connected tape splicing, the described tape splicing one end that is electrically connected is fixed on linkage section, and the other end is fixed on bus duct A and holds or on bus duct B end, described linkage comprises at least one pulley and steel rope, and described pulley is fixed on above-mentioned quiet joint, and steel rope one end is fixed on dynamic joint, and the described steel rope other end is connected with providing the engine installation of pulling force through pulley.
Record in 7th page the 35th section in specification sheets disclosed in this patent, linkage section is in the Flood gate place in tunnel, and when linkage section is connected between bus duct A end with bus duct B end, Flood gate or closed guard gate cannot close.When needs close Flood gate or closed guard gate, Flood gate can give steel rope application force, steel rope is by pulley three, pulley five, pulley two, pulley four and pulley one, overcome the elastic force that spring produces, finally pull dynamic joint to move towards dynamic joint, be set in dynamic joint on linkage section two ends after mobile one section of process, dynamic joint and linkage section are separated from, now, linkage section is just held by bus duct A and has been dropped down between bus duct B end; Then, Flood gate or closed guard gate continue to close, and continue to steel rope application force, steel rope is pulled off under the effect of this application force, and such linkage section is suspended on bus duct A end under the effect of the tape splicing that is electrically connected, and Flood gate or closed guard gate can be closed completely.
But in actual use, the closedown strength of Flood gate possibly cannot break steel rope, and meanwhile, owing to being provided with too many pulley, steel rope easily blocks, and leading actuating armature cannot move, and causes linkage section to drop smoothly like this.
