Bidirectional synchronous driving mechanism of walking unit of main cable inspection device

The utility model discloses a bidirectional synchronous driving mechanism of a walking unit of a main cable inspection device, belongs to the technical field of main cable inspection, and solves the problem that an existing main cable inspection device cannot cross a handrail rope vertical rod obstacle. The double-star synchronous driving mechanism comprises a push rod for pushing the walking unit to stretch out and draw back and a force arm rod capable of swinging around the middle of the push rod in a reciprocating mode, one end of the push rod is connected with the walking unit, and the other end of the push rod is movably connected with one end of the force arm rod. The other ends of the force arm rods are jointly and movably connected with a driving assembly which links the two force arm rods to swing in a reciprocating mode. According to the bidirectional synchronous driving mechanism, the walking unit can be driven to horizontally stretch out and draw back, and the handrail rope vertical rod can be sta
