Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings and examples.

The utility model provides a can climb handling device of stair, includes scalable light rail (track) 5, assembled

dead lever

61 and 62, jack 7, welding have the centre gripping gyro wheel 3, electric fork truck 4 of anchor clamps. The clamping rollers 3 are symmetrically clamped at the bottom of the transported instrument (goods) 2; the telescopic light rail 5 is used as a moving rail for clamping the roller 3; the assembly type fixing rod 6 consists of three parts, namely two internal thread sleeves 611 and a screw 612 with bidirectional threads; a jack 7 for jacking up the light and small hoisting equipment of the heavy object through the top bracket; the electric forklift 4 is a warehouse logistics carrying device for carrying goods.

Specifically, the upper part of the telescopic light rail 5 is U-shaped, so that a track is provided for the movement of the clamping roller, and the lower part of the telescopic light rail is semicircular, so that the dead weight is reduced; one end of the light rail can be telescopic, so that a longer rail can be provided for the movement of the roller 3; bolts 8 are welded on the inner sides of the two ends of the light rail 5 and used for fixing the fixing rod; the distance between the two light rails 5 is determined by the distance between the clamping rollers 3.
