Technical Field

The invention relates to a spiral ladder.

Background

At present, the stairs, particularly the spiral ladder, can only realize transportation or conveying of goods which cannot be realized by walking of personnel, and the living bodies of some spirals can realize integral conveying basically through an integrated conveying belt although the goods can be conveyed, so that the walking of the personnel during operation cannot be realized.

Disclosure of Invention

In view of the above problems, the present invention provides a spiral ladder which can be used for both walking and freight transportation.

In order to achieve the purpose, the invention provides the technical scheme that:

a spiral ladder is characterized by comprising

The stand and form helical spiral frame around the stand.

The spiral rack is evenly provided with stair units, the stair units comprise fan-shaped transmission belt steps and buffer devices on the outer sides, the buffer devices comprise sliding wheels fixed on a sliding wheel frame, the sliding wheel frame is fixed on the fan-shaped transmission belt steps,

the fan-shaped transmission belt step comprises a first transmission belt, a second transmission belt, a support frame, a transmission belt driving motor, an output shaft and a support frame, wherein two driving synchronous belt wheels are connected with the first transmission belt and the second transmission belt and transmit the power of the output shaft to the two transmission belts, so that the two transmission belts run at the same speed, the wide belt of the second transmission belt is slightly larger than the width of the first transmission belt, the fan-shaped conversion is realized, and the application of the second transmission belt step on the spiral ladder is possible,

the support frame is used for personnel's walking to do not receive the influence of inside output shaft, realized the mutual noninterference of people goods.
