Description
Technical field
The present invention relates to a kind of subway tunnel, the bus-bar joint mechanism of particularly a kind of subway tunnel.
Background technology
With the fast development that urban rail transit in China is built, the form of rigid suspension catenary is widely adopted.Just
Property suspension contact net be that the system that bus-bar from beginning to end is constituted is embedded in by contact line, it is electric railway locomotive and rail
The visual plant of road vehicular traffic power supply, its quality good or not directly influences the operation of locomotive.
Flood gate is all devised in urban subway tunnel construction, when the special circumstances of war and serious leak are run into,
The Flood gate and Flood gate in quick closedown tunnel are needed, to ensure tunnel and personal security.But, under the stop of bus-bar,
Flood gate cannot be closed thoroughly, it is necessary to send special personnel to enter into tunnel, by one section of bus-bar at Flood gate from whole
Disassembled on contact net system, when the situation is critical or water is larger, personnel cannot propagate into tunnel, even if can enter
Tunnel, because existing design problem also causes that dismounting is more time-consuming.
In order to solve this problem, by retrieval find Chinese patent disclose a kind of rigid contact net can breakaway-element conflux
Row's piecing devices (Application No.：201110361724.5) a kind of dis-connectable busbar joint device of rigid catenary, including
Bus-bar A ends, bus-bar B ends and the linkage section in being used to connect between the two, it is characterised in that described bus-bar A ends
It is connected with the two ends of linkage section by a sliding-type bus-bar joint respectively with bus-bar B ends, described slideable remittance
Stream row's joint includes power supply arm support, quiet joint and dynamic joint, and described quiet joint is fixed on power supply arm support, and described is dynamic
Joint is arranged in power supply arm support, and can be along supply arm bracket slide；Above-mentioned dynamic joint is respectively sleeved at linkage section
On two ends, and slidable connection is formed with linkage section, above-mentioned quiet joint is fixedly connected with bus-bar A ends and bus-bar B ends respectively；
The linkage that can make joint that linkage section is moved out towards quiet joint is provided with dynamic joint；Described linkage section and remittance
An electrical connection band is additionally provided between stream row A ends or bus-bar B ends, described electrical connection band one end is fixed on linkage section, another
End is fixed on bus-bar A ends or bus-bar B ends；Described linkage includes at least one pulley and steel wire rope, described
Pulley is fixed on above-mentioned quiet joint, and steel wire rope one end is fixed on dynamic joint, and the described steel wire rope other end is passed through to be slided
Wheel is connected with the power set that can provide pulling force.
In specification disclosed in the patent described in the 35th section of page 7, linkage section is at the Flood gate in tunnel, when even
Connect section to be connected to when between bus-bar A ends and bus-bar B ends, Flood gate or closed guard gate cannot close.Prevent when needing to close
When flooding door or closed guard gate, Flood gate passes through pulley three, pulley five, pulley two, pulley can to one active force of steel wire rope, steel wire rope
Four and pulley one, the elastic force for overcoming spring to produce finally pulls dynamic joint towards dynamic joint movement, is set in linkage section two ends
On dynamic joint after mobile one section of process, dynamic joint and linkage section are separated from, and now, linkage section is just by bus-bar A ends and remittance
Stream row B is dropped down between end；Then, Flood gate or closed guard gate continue to close, and continue to exist to steel wire rope active force, steel wire rope
It is pulled off in the presence of the active force, such linkage section is suspended on bus-bar A ends in the presence of band is electrically connected, and makes Flood gate
Or closed guard gate can completely close.
But in actual use, the closing strength of Flood gate possibly cannot break steel wire rope, simultaneously as setting
Too many pulley, steel wire rope is easily blocked, and leading actuating armature cannot move, so cause linkage section smoothly to drop.
The content of the invention
The purpose of the present invention is directed to existing technology and there is above mentioned problem, it is proposed that it is a kind of when being intake in tunnel can and
When close Flood gate subway tunnel bus-bar joint mechanism, the piecing devices also have the spy that can make that linkage section smoothly drops
Point.
