One end of the screw is respectively screwed with two welding bolts, and the two ends of the screw are screwed into the other ends of the two inner threaded sleeves respectively, thereby realizing the fixation between a pair of retractable rails, and between a pair of retractable rails The distance is determined by the distance between the clamping rollers.

Preferably, the top of the telescopic rail is U-shaped for rolling fit with the clamping roller, and the bottom of the retractable rail is semi-circular, which reduces its own weight.

The clamping roller in the utility model is symmetrically clamped at the bottom of the transported goods to ensure the smooth movement of the goods; the retractable light rail is used as the moving rail of the clamping roller, and one end of the retractable light rail is retractable and can Provides a longer track for the movement of the rollers. As a light and small lifting device that lifts heavy objects through the top bracket, the jack lifts one of the fixed rods through the top bracket to raise the telescopic end of the track; electric forklifts are warehousing and logistics handling equipment for ordinary cargo handling. The fork lifts the other retaining rod, raising the other end of the track.

The utility model has the following advantages:

1. Able to climb stairs and work in a stable state, which greatly reduces the burden of the staff;

2. Simple structure, easy to use;

3. The transported instrument always moves in a straight line, and the center of gravity fluctuates little;

4. During the transportation of the instrument, as long as there is a person who gently supports the trolley to control the speed change and forward direction of the trolley, the work efficiency and safety are greatly improved.

Detailed ways

The embodiments of the present utility model will be further described below with reference to the accompanying drawings and examples.

A conveying device capable of climbing stairs, comprising a retractable light rail (track) 5 , assembled fixing rods 61 and 62 , a jack 7 , a clamping roller 3 welded with a clamp, and an electric forklift 4 . The clamping roller 3 is symmetrically clamped at the bottom of the transported instrument (goods) 2; the telescopic light rail 5 is used as the moving track of the clamping roller 3; the assembled fixing rod 6 is composed of three parts, two internal thread sleeves 611 and a screw 612 with bidirectional threads; jack 7, a light and small lifting device that lifts heavy objects through the top bracket; electric forklift 4 is a warehousing and logistics handling equipment for general handling of goods.

Specifically, the telescopic light rail 5, the upper part is U-shaped, provides a track for the movement of the clamping roller, and the lower part is semi-circular, which reduces the self-weight; one end of the light rail is retractable, which can provide a longer track for the movement of the roller 3; Bolts 8 are welded on the inner side of both ends for fixing the fixing rod; the distance between the two light rails 5 is determined by the distance between the clamping rollers 3 .
