With the rapid development of economic construction in China, the market demands for various straddle type monorail traffic joint type five-way turnouts are increasing day by day.
In order to meet the requirement of the whole-line operation of the urban overhead light rail, different turnout forms, such as single turnout, double-crossover turnout, three turnout, five turnout and the like, are generally arranged in different turnout areas of the light rail. The straddle type monorail transit joint type turnout system is a beam-rail integrated turnout system, namely, the turnout is not only a track for running a vehicle, but also a turnout for line switching of the vehicle. The driving device of the turnout is not only the power for pushing the turnout system to switch, but also mainly ensures that the turnout beam is switched according to the specified line shape. The driving device mainly comprises a motor, a speed reducer, a transmission shaft, a coupling and the like. The speed reducer drives the rotating arm to rotate along the central shaft of the output shaft of the speed reducer, the rotating arm roller rotates and slides along the guide sliding groove of the turnout beam, and the speed reducer passes through different rotating arms and rotating angles, so that the switching of the turnout is realized.
When a worm gear reducer or a rotating arm of a five-way turnout of a Baoqiao needs to be replaced or maintained, the rotating arm needs to be pulled out of the reducer, the rotating arm and the reducer are very tightly connected due to long-term operation of a light rail, the rotating arm is difficult to pull out of the reducer by manpower, and few special disassembling tools for the worm gear reducer and the rotating arm of the five-way turnout of the Baoqiao are available on the market at present.
