The utility model has the advantages of high transmission current, being safe and reliable, convenient installation and perfect technological properties.
Description
Technical field
The utility model relates to the rigid suspended two-wire contact system of a kind of compound type, belongs to the equipment of track traffic power supply usefulness.
Background technology
Before the utility model is made, in prior art, only embed a copper contact wire in the aluminum alloy bus duct of the rigid suspension catenary of track traffics such as subterranean railway, transmission current is less than normal, and the bow net contact reliability is low, and abrasion is big.Though it is the rigid suspended two-wire contact system device of ZL200420122393.5 that application number is arranged, the aluminum alloy bus duct expressing technique difficulty of this utility model is bigger than normal.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of rigid suspended single line contact system, with the technology of maturation provide a kind of can the bigger electric current of transmission, the rigid suspended two-wire contact system of compound type that mobile power supply reliability is higher.
Main solution of the present utility model is achieved in that
The utility model mainly adopts symmetrical two aluminum alloy bus ducts 1 to be combined into a complete aluminum alloy bus duct by " H " shape aluminium section bar 2.Each independent aluminum alloy bus duct 1 has a dovetail furrow, two grooves 4 and a journal stirrup 5.Complete bus duct just has two dovetail furrows, four grooves 4 and two journal stirrups 5.Two copper contact wires 3 are embedded respectively in two dovetail furrows of aluminum alloy bus duct, add main suspension hook, middle connector, rigid-flexibility transition section, expansion pipe, the anchor etc. paid and constitute the rigid suspended two-wire contact system of compound type.
Compared with the prior art the utility model has the following advantages:
1. transmission current is big.Because the total sectional area of aluminum alloy bus duct strengthens nearly one times, transmission current can corresponding increase nearly one times, saves the direct current (DC) feeder line.
2. reliability and safe.Bus duct and copper contact wire do not have the longitudinal force effect when using, and the disconnection fault rate is low, and abrasion reduces by half.
3. the temperature rise that continues under the current-carrying reduces by half, and the fire hazard of contact net for power supplying reduces.
4. good manufacturability.The expressing technique improvement of terms of aluminum alloy bus duct.
5. easy for installation.Bus duct is fixing easily, and the similar slide fastener of going up of copper contact wire equally is embedded into bus duct.
Description of drawings
Fig. 1 is the cross-sectional configuration figure of the utility model agent structure in the installation site.
The specific embodiment
The embodiment of following the utility model in conjunction with the accompanying drawings is further described: enforcement of the present utility model, and at first to make aluminum alloy bus duct 1, " H " shape aluminium section bar 2, copper contact wire 3 respectively, pay suspension hook 6, main suspension hook 8 and other parts in addition.Aluminum alloy bus duct 1 and " H " shape aluminium section bar 2 can be made extrusion molding on extrusion press behind the mould, generally long 10 meters to 15 meters.Two bus ducts 1 one positive one are arranged in about anti-together the back will the respective grooves of " H " shape aluminium section bar 2 insertion bus ducts 1 from the termination in, be combined into a complete aluminum alloy bus duct by two bus ducts 1 and " H " type aluminium section bar 2.All parts are transported in the subway tunnel install.Earlier on the prefabricated sagging steel member of tunnel top, fixedly load onto insulator behind the cross-arm, the center of insulator mounting hole is far from " pulling out " value of tunnel longitudinal center linear distance on the cross-arm, " pull out " value and make the center of insulator and contact system be normal distribution, evenly in order to the pantograph abrasion.With M16 bolt 9 main suspension hook 8 is fixed on the insulator, complete bus duct is raised, its upper left corner is snapped in the lower left groove of main suspension hook 8; Fastening with paying behind the upper right corner that suspension hook 6 blocks bus duct again with main suspension hook 8 with bolt 7, make bus duct be fixed on the sky, tunnel.A main suspension hook 8 and a pair suspension hook 6 are combined into complete suspender.Copper contact wire is installed on the left and right sides journal stirrup 5 that dolly hangs over the aluminum alloy bus duct, open with the dovetail furrow of instrument the aluminum alloy bus duct, 2 wheels that rise that dolly is installed are stuck in the other groove 4 of the dovetail furrows two of bus duct 1, the top of copper contact wire 3 is embedded dovetail furrow, copper contact wire is installed dolly with the same moved further of the wheeled cable drum carriage on the traveling rail, will copper contact wire 3 be embedded in the dovetail furrow of aluminum alloy bus duct 1 as slide fastener; Repeat above-mentioned action, just another root copper contact wire 3 is embedded in another dovetail furrow of aluminum alloy bus duct 1.Connector, rigid-flexibility transition section, expansion pipe, anchor, section insulator etc. in the middle of adding, just in the tunnel, constitute the rigid suspended two-wire contact system of complete compound type, with the DC1500V direct current (DC) at traction power supply station on pantograph passes to electric locomotive in the motion.
Claims (3)
1. rigid suspended two-wire contact system of compound type, it is characterized in that being combined into complete bus duct by two symmetrical aluminum alloy bus ducts (1) and " H " shape aluminium section bar (2), have two dovetail furrows, two journal stirrups (5) and four grooves (4), two dovetail furrows at bus duct are embedded in two copper contact wires (3) again.
2. the rigid suspended two-wire contact system of compound type according to claim 1 is characterized in that each independent aluminum alloy bus duct (1) has a dovetail furrow, two grooves (4) and a journal stirrup (5).
