Insulation detection device for bus lifting frame

The utility model discloses an insulation detection device for a bus lifting frame. The insulation detection device carries out insulation detection on the bus lifting frame through an insulation detection megger. Comprising two detection lines which are electrically connected to the outer side of an insulation detection megger, and the sides of the two detection lines are respectively provided with a positive detection probe and a negative detection probe; the detection contact heads are in corresponding contact with the positive electrode detection probe and the negative electrode detection probe, and the detection contact heads are mounted on the left side and the right side of the exterior of the line protection block; the cable transmission pipes are symmetrically and fixedly installed on the left side and the right side of the outer portion of the guide frame. According to the insulation detection device for the bus lifting frame, a novel structural design is adopted, so that the device is provided with
