The straddle type monorail transit has the advantages of low noise, small turning radius, strong climbing capability, low construction cost, short period and the like, and gradually becomes a main form of diversified development of urban rail transit. The single-rail turnout is one of three key technologies of straddle type single-rail traffic, and mainly relates to two major types of sectional turnout and integral turnout. The drive mode of the joint type turnout in the joint type turnout is that a worm gear reducer drives a rotating arm to rotate along the central shaft of an output shaft of the reducer, a rotating arm roller rotationally slides along a guide sliding groove of a turnout beam, and the worm gear reducer realizes the switching of the turnout through different rotating arms and rotating angles. The driving device mainly comprises a motor, a speed reducer, a transmission shaft, a coupling and the like.

According to the technical specification and the design requirement of the single-rail turnout, after the line operation of each group of turnouts exceeds a certain period, major repair is required. The overhaul of the single-track turnout has the limitations that the normal operation of the line cannot be influenced, the construction operation time is limited, the operation position is special (mainly on a viaduct platform or an underground tunnel), and the like. At present, the speed reducer is transferred mainly by mechanically jacking a certain space during overhaul of a single-rail turnout, then the speed reducer is translated from the bottom of the turnout beam by adopting a roller translation mode, and finally the precision of the adjusting position of the speed reducer is poorer when the speed reducer is restored by the same method. Therefore, the existing mode is complex to operate, low in efficiency, time-consuming and labor-consuming.

Furthermore, the single-track turnout comprises a turnout beam body 1, an inter-beam connecting device 2, a beam body trolley 3, a driving device 4 and the like. The turnout beam body 1 is of a box-type structure, is a bearing and guiding component of a vehicle, and is provided with a panel structure for supporting a vehicle traveling wheel, a stabilizing wheel and a guide wheel. The beam-to-beam connecting device 2 not only ensures that the whole turnout as a whole bears the load of a vehicle, but also ensures that each section of beam body can generate relative movement in a certain space range. The trolleys 3 are carriers for beam movement, bear vertical loads of the turnout beam and the vehicle, and move together with the turnout beam around the fixed pin shaft under the action of driving force generated by the driving device, so that the switching of the turnout is realized. The driving device 4 adopts a motor to provide driving power to drive a switch speed reducer with vertical input and output to synchronously rotate, and then drives each section of turnout beam body under the instruction of a control system through a rotating arm-guide groove mechanism to realize the switch displacement of the turnout according to a specified track.
