Problems solved by technology
[0005] The curves of the existing joint-type turnouts and joint-flexible turnouts in China are not smooth enough when they join the light rail track, which reduces the comfort of light rail trains and even affects safety; even the joint-flexible turnouts also have certain broken lines The structure affects the driving of the vehicle; and the structure is extremely complex, the failure rate is high, the speed is limited, the amount of maintenance and repair is large, the service life is short, and the cost is high

The invention discloses a split turnout. The split turnout comprises a first turnout beam, a second turnout beam, a movable end fixing section, a second connecting piece, tail shafts, pivot end fixing sections, a plurality of walking trolleys, a driving device, a first connecting piece and a plurality of bottom plates. The bottom of the first turnout beam and the bottom of the second turnout beam are fixedly connected with the walking trolleys. The tail end of the first turnout beam and the tail end of the second turnout beam are connected with the pivot end fixing sections on the bottom plates respectively in an abutting mode. The walking trolleys connected to the fixed end of the first turnout beam and the fixed end of the second turnout beam are rotationally connected with the tail shafts arranged on the bottom plates. The first turnout beam and the second turnout beam are connected in a hinged mode through the first connecting piece. The movable end of the second turnout beam is fixedly connected with the corresponding movable end fixing section on the corresponding bottom plate through a locking device. The second turnout beam is connected with the driving device on the corresponding bottom plate through the second connecting piece. By means of the split turnout, the driving efficiency and safety of a light rail can be improved, and construction cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of monorail traffic, in particular to a straddle-type monorail replacement beam-type split turnout. Background technique [0002] Light rail is an important part of urban rail transit. For cities with relatively large height differences, dense population, narrow roads, steep slopes and sharp bends, and congested traffic, light rail can well solve the problem of traffic congestion. Especially the straddle-type monorail traffic light rail is more adaptable to the traffic conditions in modern cities. [0003] Straddle-type monorail traffic is a traffic system in which a track beam is used as a rail, and a train rides on the track beam, that is, a single track beam is used to support, stabilize and guide the movement of the train. The technical characteristics are mainly reflected in the three aspects of the vehicle bogie, track beam and line switch. The running mechanism is completely different from the steel ...
