For solving the problems of the technologies described above, the utility model tunnel divides the tension compensating contact system with the technical scheme of rigid suspended employing to be: comprise by the fixing bracket pipe of fixed mechanism and tunnel wall and be placed in the insulating tube that both sides on this bracket pipe have insulated leg, between described insulating tube, be provided with permanent seat, below described permanent seat, be provided with adapting pipe, in described adapting pipe, be inserted with the bus duct fixed bearing that is fixed with bus duct, at described bus duct internal fixation contact wire is arranged, described bracket pipe is provided with spacing ring, is provided with guide spring between described spacing ring and permanent seat.
Its additional technical feature is:
Described insulating tube and permanent seat are connected as a single entity;
Described bracket pipe is provided with first and regulates round, and described spacing ring is fixed on the described bracket pipe by passing described first bearing pin of regulating round;
Close fixed seating installs and is equipped with spacing hole on described bracket pipe, is provided with locating dowel pin in described spacing hole;
Be provided with damping spring described accepting between sleeve pipe and the bus duct fixed bearing;
Tunnel provided by the utility model divides the tension compensating contact system compared with prior art to have the following advantages with rigid suspended: one, since comprise by the fixing bracket pipe of fixed mechanism and tunnel wall be placed in both sides on this bracket pipe and have the insulating tube of insulated leg, between described insulating tube, be provided with permanent seat, below described permanent seat, be provided with adapting pipe, in described adapting pipe, be inserted with the bus duct fixed bearing that is fixed with bus duct, at described bus duct internal fixation contact wire is arranged, described bracket pipe is provided with spacing ring, between described spacing ring and permanent seat, be provided with guide spring, like this, bus duct is designed to " S " type along the direct route direction, the bus duct fixed bearing that this tunnel is rigid suspended is stuck in the position, arc top of " S " type bus duct, utilize guide spring to promote to be enclosed within bus duct fixed bearing on the bracket pipe, and utilize positive and negative stagger, it is curved to make bus duct form S shape, rely on the size of stagger to realize that the temperature difference variable of bus duct moves towards, the tunnel rigid suspension catenary adopts bus duct not have the expansion joints connection, establish anchor point at the tunnel two ends, bus duct is installed continuously in the tunnel, and bus duct goes out to be worth the curved next change of freely limitting of S shape because the variation of temperature amount utilizes circuit " to draw "; They are two years old, because described bracket pipe is provided with first and regulates round, described spacing ring is fixed on the described bracket pipe by passing described first bearing pin of regulating round, like this, in installation process, can regulate the position of spacing ring on the bracket pipe according to actual needs, thereby regulate the elastic force size of guide spring; Its three owing on described bracket pipe, install and be equipped with spacing hole, in described spacing hole, be provided with locating dowel pin near the fixed seating, can prevent that permanent seat from driving the scope that contact wire departs from pantograph; Its four owing to be provided with damping spring, reduced to give each position and brought damage because of vibrations described accepting between sleeve pipe and the bus duct fixed bearing.
Description of drawings
Fig. 1 divides the tension compensating contact system with rigid suspended structural representation for the utility model tunnel;
Fig. 2 divides the tension compensating contact system with rigid suspended structural representation for another kind of tunnel.
The specific embodiment
Divide the tension compensating contact system to be described in further details below in conjunction with accompanying drawing to the utility model tunnel with rigid suspended structure and use principle.
As shown in Figure 1, the utility model tunnel divides the tension compensating contact system with rigid suspended structural representation, this tunnel divides the tension compensating contact system to comprise by the fixing bracket pipe 3 of fixed mechanism 1 and tunnel wall 2 with rigid suspended, be with the insulating tube 72 that both sides have insulated leg 71 at bracket pipe 3, between two insulating tubes 72, be provided with permanent seat 4, below permanent seat 4, be provided with adapting pipe 42, in adapting pipe 42, be inserted with bus duct fixed bearing 43, on bus duct fixed bearing 43, be fixed with bus duct 44, at bus duct 44 internal fixation contact wire 5 is arranged, end at bracket pipe 3 is provided with spacing ring 31, is provided with guide spring 6 between spacing ring 31 and permanent seat 4.Like this, bus duct 44 is designed to " S " type along the direct route direction, the bus duct fixed bearing 43 that this tunnel is rigid suspended is stuck in the position, arc top of " S " type bus duct 44, utilize guide spring 6 to promote to be enclosed within bus duct fixed bearing 43 on the bracket pipe 3, and utilize positive and negative stagger, it is curved to make bus duct form S shape, rely on the size of stagger to realize that the temperature difference variable of bus duct moves towards, the tunnel rigid suspension catenary adopts bus duct not have the expansion joints connection, establish anchor point at the tunnel two ends, bus duct is installed continuously in the tunnel, and bus duct goes out to be worth the curved next change of freely limitting of S shape because the variation of temperature amount utilizes circuit " to draw ".
