Abstract

The utility model relates to a rigid and flexible transition section bus of a rigid mobile contact network. One end of a bus body (1) is provided with an upward tilted elbow, the inner cavity at the middle part of the bus body (1) is fixed with a cushion block (2), the lower end of the cushion block (2) is provided with a rectangle gap (3), the lower end of the bus body (1) is provided with a gap (4) corresponding to the rectangle gap (3), the gap (3) is coincident with the gap (4), a contact wire (5) is clamped on a clamping hole at the lower end of a contact wire clip (6) and a nipper jaw at the lower end of the bus, and the contact wire clip (6) is positioned in the gaps (3, 4). The utility model loads the anchorage tension of a flexible contact wire through the clamp force of the nipper jaw of the bus and a contact wire joint wire clip, causes the contact network of the flexible contact wire to directly enter into the rigid and flexible transition section bus after the anchorage, and ensures the smooth transition of the engine pantograph type current collector from a flexible contact network to the rigid mobile contact network.

Description

Rigidity mobile catenary rigid-flexibility transition section bus duct

Technical field

The utility model relates to a kind of rigidity mobile catenary rigid-flexibility transition section bus duct.

Background technology

Rigidity mobile catenary wiring arrangement is generally formed by moving section and canned paragraph two parts, and mobile section is arranged on mobile catenary circuit middle part, can move to the pillar side, discharges the circuit upper space; Canned paragraph is arranged on mobile catenary circuit two ends, and rigid-flexibility transition section bus duct is the chief component of canned paragraph, realizes being connected of rigidity mobile catenary and flexible contact system by rigid-flexibility transition section bus duct.Rigid-flexibility transition section bus duct is installed in rigidity mobile catenary two ends, directly enters rigid-flexibility transition section bus duct after flexible contact system contact wire casts anchor, and has guaranteed that motorcycle pantograph is from flexible contact system seamlessly transitting to the rigidity mobile catenary.

Summary of the invention

The technical matters that the utility model solves: design a kind of rigidity mobile catenary rigid-flexibility transition section bus duct, adopt the aluminum alloy bus duct to be processed into, bear the flexible contact wire tension force that casts anchor by bus duct self jaw gripping power and contact wire splice, directly enter rigid-flexibility transition section bus duct after flexible contact system contact wire is casted anchor, guaranteed that motorcycle pantograph is from flexible contact system seamlessly transitting to the rigidity mobile catenary.

Technical solution of the present utility model: a kind of rigidity mobile catenary rigid-flexibility transition section bus duct, one end of its bus duct body (1) is the elbow that is upturned, be fixed with cushion block (2) in the middle part inner chamber of bus duct body (1), the lower end of cushion block (2) is shaped on rectangular indentation (3), also be shaped on cooresponding breach (4) and breach (3 with the corresponding bus duct body of rectangular indentation (3) (1) lower end, 4) match, contact wire (5) is clamped on the jaw of the clamp port of contact wire wire clamp (6) lower end and bus duct lower end, and contact wire wire clamp (6) is positioned in the breach (3,4).

The lower end clamp port of described contact wire wire clamp (6) is corresponding with the jaw of bus duct lower end.

Advantage that the utility model compared with prior art has and effect:

1, bears the flexible contact wire tension force that casts anchor by the location of bus duct self jaw gripping power and contact wire splice, need not flexible contact wire is additionally casted anchor, can reduce cost, conveniently install, structure is attractive in appearance.

2, the interface transition with the rigidity section of moving realizes by rigid-flexibility transition section bus duct body end simmering and bending structure, guarantees mutual seamlessly transitting fully.

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.

A kind of rigidity mobile catenary rigid-flexibility transition section bus duct, one end of its bus duct body (1) is the elbow that is upturned, be fixed with cushion block (2) in the middle part inner chamber of bus duct body (1), the lower end of cushion block (2) is shaped on rectangular indentation (3), also be shaped on cooresponding breach (4) and breach (3 with the corresponding bus duct body of rectangular indentation (3) (1) lower end, 4) match, contact wire (5) is clamped on the jaw of the clamp port of contact wire wire clamp (6) lower end and bus duct lower end, and contact wire wire clamp (6) is positioned in the breach (3,4).And the lower end clamp port of contact wire wire clamp (6) is corresponding with the jaw of bus duct lower end.

Rigid-flexibility transition section bus duct is installed in rigidity mobile catenary two ends during use.The contact wire (5) of flexiblesystem end is clamped on the jaw of the clamp port of contact wire wire clamp (6) lower end and bus duct lower end, on the one hand bear the flexible contact wire tension force that casts anchor by bus duct self jaw gripping power and contact wire splice, on the other hand because contact wire wire clamp (6) is positioned at breach (3,4) in, be subjected to stopping of cushion block (2) about contact wire wire clamp (6) to bear the flexible contact wire tension force that casts anchor.Directly enter rigid-flexibility transition section bus duct after flexible contact system contact wire is casted anchor, guaranteed that motorcycle pantograph is from flexible contact system seamlessly transitting to the rigidity mobile catenary.Realize by rigid-flexibility transition section bus duct body end simmering and bending structure with the interface transition of the rigidity section of moving.

Claims

1, a kind of rigidity mobile catenary rigid-flexibility transition section bus duct, it is characterized in that: an end of bus duct body (1) is the elbow that is upturned, be fixed with cushion block (2) in the middle part inner chamber of bus duct body (1), the lower end of cushion block (2) is shaped on rectangular indentation (3), also be shaped on cooresponding breach (4) and breach (3 with the corresponding bus duct body of rectangular indentation (3) (1) lower end, 4) match, contact wire (5) is clamped on the jaw of the clamp port of contact wire wire clamp (6) lower end and bus duct lower end, and contact wire wire clamp (6) is positioned in the breach (3,4).
