Description
Technical field
The utility model belongs to the track traffic technical field, but relates to a kind of rigid contact net breakaway-element bus duct piecing devices, but the stop gear in particularly a kind of rigid contact net breakaway-element bus duct piecing devices.
Background technology
Contact system is in the electrification railway, and " it " font sets up along the rail sky, supplies pantograph to get the high voltage transmission line of stream.Contact system is the main truss of railway electrification engineering, is the transmission line of electricity to the special shape of electric locomotive power supply that set up in the downline sky.
Rigid suspension catenary is to embed the system that bus duct constituted from beginning to end by contact wire, is extensively adopted by modern railway transportation.In the city underground tunnel construction, all designed the closed guard gate; Designed the anti-door that floods in the time of below the tunnel passes the river course; Rigid suspension catenary needs the closed guard gate in quick closedown tunnel to flood door with anti-, to guarantee tunnel and personnel's safety when the extraordinary circumstances that run into war and seriously leak.Under the stopping of bus duct joint, anti-flood door or the closed guard gate can't thoroughly close, but designed rigid contact net breakaway-element bus duct piecing devices for this reason, comprise linkage section, electric arm support, moving joint, quiet joint, bus duct A end, bus duct B end etc.Linkage section is in the middle of bus duct A end and the bus duct B end; Bus duct A end is connected with the two ends of linkage section through a slideable bus duct joint respectively with bus duct B end; Slideable bus duct joint comprises feeding section support, quiet joint and moving joint; Quiet joint is fixed on the feeding section support, and moving joint is arranged in the feeding section support, and can slide along the feeding section support; Moving joint is set in respectively on the two ends of linkage section, and slidably is connected with linkage section formation, and quiet joint is connected with bus duct A end and bus duct B end respectively mutually; On moving joint, being provided with to make joint move and break away from the linkage of linkage section towards quiet joint.Linkage section is in anti-in the tunnel and floods door or closed guard gate place, when linkage section is connected between bus duct A end and the bus duct B end, anti-ly floods door or the closed guard gate can't close, so linkage section need break away from, and moving joint is anti-to flood door or the closed guard gate could close fully.
Close anti-when flooding door or closed guard gate; Owing to have friction force between moving joint and the linkage section; Moving joint can occur driving the situation that linkage section slides together in the process that moves, and makes linkage section can't break away from moving joint; Cause linkage section not break and to fall down, make and anti-ly to flood door or the closed guard gate can't close fully by whole device.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology; But the stop gear in a kind of rigid contact net breakaway-element bus duct piecing devices has been proposed, this stop gear can make joint in the process that moves smoothly with the open circuited characteristics of linkage section.
The purpose of the utility model can realize through following technical proposal: but the stop gear in a kind of rigid contact net breakaway-element bus duct piecing devices; Described bus duct piecing devices comprise feeding section support, linkage section and moving joint; Described moving joint is arranged in the feeding section support, and can slide along the feeding section support, is provided with chute in the described moving joint; Described linkage section end is arranged in the chute of moving joint; It is characterized in that this stop gear comprises being arranged on and can prevent the position limiting structure that linkage section slides along chute on the linkage section that described position limiting structure can act on the above-mentioned feeding section support.
But rigid contact net breakaway-element bus duct piecing devices mainly are to be applied in the tunnel, and linkage section is positioned at and anti-floods door or closed guard gate place, but linkage section does not break when falling down from rigid contact net breakaway-element bus duct piecing devices; Anti-flood door or the closed guard gate can't close fully, anti-when flooding door or closed guard gate and need close, moving joint sliding and linkage section disengaging; Owing to have friction force between moving joint and the linkage section, the moving laced belt section of being dynamically connected causes linkage section to break away from moving joint; Therefore, stop gear is set on linkage section prevents that linkage section from sliding along chute, because not follow-up connector motion of linkage section; After moving joint sliding certain distance; Linkage section just breaks away from moving joint, realizes that linkage section drops from whole device, makes anti-ly to flood door or the closed guard gate can close fully.
But in the stop gear in above-mentioned rigid contact net breakaway-element bus duct piecing devices; Described position limiting structure comprises anchor clamps one and anchor clamps two; Described anchor clamps one are clamped on the above-mentioned linkage section with anchor clamps two, and through fastener both are fixed on the linkage section between described anchor clamps one and the anchor clamps two.Moving joint under the effect of anchor clamps one or anchor clamps two or fastener, makes joint can't drive linkage section in the process that moves.
As other a kind of situation; But in the stop gear in above-mentioned rigid contact net breakaway-element bus duct piecing devices; Described position limiting structure is a limited post, and described limited post is fixed on the above-mentioned linkage section, and limited post can be resisted against on the above-mentioned feeding section support.Limited post is fixed on the certain position of linkage section, makes linkage section to be arranged in the chute of moving joint by designing requirement, also can in the moving laced belt section of being dynamically connected motion, play position-limiting action.
But in the stop gear in above-mentioned rigid contact net breakaway-element bus duct piecing devices, described fastener is a bolt, and described bolt passes above-mentioned anchor clamps one simultaneously and with anchor clamps two anchor clamps one and anchor clamps two is fixed on the linkage section.
But in the stop gear in above-mentioned rigid contact net breakaway-element bus duct piecing devices, have a limiting section on the described feeding section support, above-mentioned bolt can be resisted against on this limiting section.When the passive joint of linkage section drove, limiting section propped up bolt and makes not follow-up connector motion of linkage section.
But in the stop gear in above-mentioned rigid contact net breakaway-element bus duct piecing devices, described limiting section and feeding section support are integral structure.The processing of easy design limiting section like this reduces productive costs.
But in the stop gear in above-mentioned rigid contact net breakaway-element bus duct piecing devices, the quantity of described bolt is two.Two bolts can simple the most firm stationary fixture one and anchor clamps two.
Compared with prior art, the utlity model has following advantage:
Therefore 1, be resisted against on the limiting section of feeding section support through the bolt between anchor clamps one and the anchor clamps two, under any circumstance can both make linkage section break away from moving joint, make and anti-ly flood door or the closed guard gate closes fully.
2, through the bolt between anchor clamps one and the anchor clamps two be resisted against realize on the limiting section of feeding section support spacing, have simple in structure, the advantage that productive costs is low.
