The purpose of this utility model is to be achieved through the following technical solutions:
A kind of curve double track is maked somebody a mere figurehead dolly, comprise trolley frame, initiatively turn dolly and passive turning dolly, the cross section of described trolley frame is several fonts, the two ends of trolley frame are respectively equipped with initiatively turn dolly and passive turning dolly, the dolly of initiatively turning is connected with operating handle, the bottom surface at trolley frame middle part is provided with projection, and projection is connected with ring-chain hoist by bolt, and the ring-chain hoist bottom is provided with suspension hook.
Further, described active turning dolly comprises symmetrical two adhesion wheel groups and motor, pass through bindiny mechanism's captive joint between two adhesion wheel groups, the below of two adhesion wheel groups is provided with guide rail, one of them adhesion wheel group is connected with motor, and the middle part of described bindiny mechanism is provided with suspension rod, and the top of suspension rod is passed bindiny mechanism and fixed by nut, be provided with bearing between suspension rod and the bindiny mechanism, the bottom of suspension rod is provided with connecting device.
Further, be provided with antifriction-bearing box in the described adhesion wheel group.
Further, described motor is arranged at the inboard of guide rail.
The beneficial effects of the utility model are: general double rail suspension driving makes it by keeping straight on or becoming and can carry out the operation of S type around track around some operations; Can be applicable to the maintenance of electric power factory equipment, particularly the restriction of power plant locus is high, can move the occasion of warp rail; Compare the method for power plant's separate unit travelling crane inspection single device, by the application of double track curve driving, realized hoisting crane maintenance multiple devices in single workshop; Reduce the fund input of power plant's maintenance, reduced the driving quantity in single workshop, be equivalent to reduce whole shop equipment energy consumption.
