Carrying device for stair

Abstract

The invention discloses a carrying device for a stair, and relates to the technical field of conveying equipment. The carrying device for the stair comprises transporting tracks, a carrying vehicle and a driving mechanism. The carrying device for the stair is suitable for a stair, by arranging the transporting tracks at the two sides of the stair in a disassembling mode, the carrying vehicle used for transporting goods goes up and down the stair through cooperating with the transporting tracks; the driving mechanism is arranged at the front end of the carrying vehicle, walking wheels at the rear end of the carrying vehicle is driven by driving for walking wheels at the front end of the carrying vehicle; and a ratchet wheel mechanism with a braking protecting function is further arranged for preventing backward slipping of the carrying vehicle. The carrying device for the stair has the characteristics of being simple but compact in structure, compared with existing small-scale carrying tools, the carrying device for the stair has greater heavy object carrying performance, installation is simple and convenient, manufacturing and maintaining cost is low, motor driving is not totally relied, and the carrying device for the stair can also be pulled out from the transporting tracks through manpower.

Description

technical field [0001] The present invention relates to the technical field of conveying equipment, in particular to a stair carrying device. Background technique [0002] In large factories or buildings, trucks are often needed to carry heavy goods that are difficult to move by manpower, so as to improve the handling efficiency. Cargo can be transported vertically or horizontally. With its compact body, flexible use, convenience, and environmental protection, the truck has become an essential tool for horizontal material transport. [0003] However, elevators that can carry goods vertically are not installed in some old factory buildings, and most of the heavy objects are still carried up the stairs by manpower. The existing handling tools on the market are either simple in structure and unreliable in operation, which cannot meet the handling needs of heavy goods; or the structure is too complicated, which leads to increased installation and maintenance costs, and once the...
