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 slide mechanism 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, at this moment need personnel to get on the bus duct joint disassembly is got off, time-consuming like this effort again.But designed rigid contact net breakaway-element bus duct piecing devices for this reason, comprised 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.Moving joint is arranged in the sliding cavity of feeding section support, drives through linkage and moves the quiet joint motion of joint court, thereby make linkage section break away from moving joint, drops from device, and realization prevents flooding door or the closed guard gate closes fully.
Because the deviation when production or use; Moving joint can be accompanied by the situation that side travel occurs when linkage drives moving joint towards quiet joint motion, makes that friction force increases between moving joint and the linkage section, has increased the required power of linkage; Serious causing blocks between moving joint and the linkage section; Linkage section can't break away from the driven joint, makes linkage section to fall down from whole device, causes anti-flooding door or the closed guard gate can't close fully.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, but has proposed the slide mechanism in a kind of rigid contact net breakaway-element bus duct piecing devices, and this slide mechanism can make joint sliding characteristics more smoothly.
The purpose of the utility model can realize through following technical proposal: but the slide mechanism in a kind of rigid contact net breakaway-element bus duct piecing devices; But described rigid contact net breakaway-element bus duct piecing devices comprise the power supply board one and power supply board two that laterally arranges; Form sliding cavity between power supply board one and the power supply board two, in sliding cavity, be provided with moving joint, in sliding cavity, also be fixed with quiet joint; Between moving joint and quiet joint, also be provided with pilot bar; Said pilot bar one end is fixed on the quiet joint, and the pilot bar other end passes described moving joint, it is characterized in that; This slide mechanism is arranged between power supply board one and power supply board two and the moving joint; Comprise the symmetrical strip through hole one and through hole two, slide bar one and slide bar two that are opened on power supply board one and the power supply board two, an end of described slide bar one is fixed on that the other end passes through hole one on the moving joint, and an end of described slide bar two is fixed on that the other end passes through hole two on the moving joint; Be provided with on all in the end of slide bar one and slide bar two and can prevent that slide bar one and slide bar two break away from the location structure of through holes one and through hole two.
But rigid contact net breakaway-element bus duct piecing devices mainly are to be applied in the tunnel, and linkage section is positioned at anti-door or the closed guard gate place flooded, when anti-when flooding door or closed guard gate and closing; Linkage drives moving joint sliding; For the side travel of anti-stop joint, through the slide bar one and slide bar two that passes through hole one and through hole two is set on moving joint, slide bar one and slide bar two in through hole one and through hole two along with moving joint sliding; Be provided with at slide bar one and slide bar two again and can prevent that slide bar one and slide bar two break away from the location structure of through hole one and through hole two; Make moving joint quiet joint direction to move, since the linkage section transfixion, the disengaging of linkage section and moving joint behind the segment distance; Make that being in anti-linkage section and the disengaging of bus duct piecing devices of flooding door or closed guard gate place drops, and accomplishes anti-the closing fully of door or closed guard gate of flooding.
But in the slide mechanism in above-mentioned rigid contact net breakaway-element bus duct piecing devices; Described location structure is a spacer; Described spacer is separately fixed on slide bar one and the slide bar two, and the width of this spacer is greater than the aperture of above-mentioned through hole one and through hole two.When spacer cross travel occurs at moving joint, can lean with power supply board, stop the cross travel of moving joint, less than the aperture of through hole one or through hole two can't with power supply board against.
But in the slide mechanism in above-mentioned rigid contact net breakaway-element bus duct piecing devices, be equipped with rolling structure between described power supply board one and power supply board two and the spacer.Through roller structure the level and smooth follow-up connector of spacer is moved towards quiet joint.
