Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of transportation machinery, and in particular relates to a building lifting platform. Background Art
[0002] A lift is a type of lifting machinery that transports people or objects vertically. It also refers to equipment for vertical transportation in logistics systems such as factories and automatic warehouses. The lift is often also equipped with various flat conveying equipment as a connecting device for conveyor lines at different heights. The four-drive lift uses four power units to lift goods at the same time, which increases the load capacity of the lift.
[0003] Most existing devices require personnel to follow the goods into the lifting platform for transportation and unloading operations, but most construction materials are too heavy. Operators carry heavy objects on the lifting platform from a high position, which not only consumes manpower but also poses certain risks. Therefore, we have proposed a construction lifting platform.
[0004] Patent document CN207632417U discloses a lifting platform, including a support beam, a base, a side baffle, a control box, a load rack, a guardrail net, a loading ramp, a column, a motor, a driving wheel, a chain, a driven wheel, a slide, a power block, a slot, a rotating rod and a sticking strip. The beneficial effect of the utility model is: by setting a side baffle on one side of the support beam, and setting a slot inside the side baffle, the two sides of the load rack are inserted into the slide slot to slide, so that when the chain pulls the load rack to rise, the load rack will not shake, so that the stability is good when transporting items, and a plurality of slots are set on one side of the base at the bottom of the support beam, and the loading ramp is inclined and can be pressed into the slot from top to bottom, so that the loading ramp can be removed when not loading goods, which does not affect the walking of nearby carts and is convenient for loading goods, and the guardrail net can be retracted into the column, which is convenient for the movement of goods when loading and unloading goods. The device has the characteristics of stable cargo transportation and convenient disassembly.
[0005] The above device does not have a mechanism for automatically transporting goods when in use, and personnel are required to push the goods into the lifting platform and rise and fall with the goods. While requiring a certain amount of manpower, when the lifting platform falls and topples over unexpectedly, it poses a certain threat to the lives of the personnel in the lifting platform.
