Problems solved by technology

When a major failure occurs during the transportation of the goods carried by the freight elevator, and the freight elevator is in a state of free fall, if the freight elevator itself does not have any safety protection facilities, passengers are easily injured or even killed
Even if the passengers are lucky and are not injured due to the failure of the freight elevator, they will still bump due to the displacement of the cargo, which greatly increases the probability of passenger injury
Therefore, there are still certain safety hazards in the freight elevators currently on the market.

Abstract

The high-safety goods elevator comprises a goods elevator cabin, a goods elevator door for goods to enter or move out of the goods elevator cabin is arranged on the side wall of the goods elevator cabin, a first groove is formed in the ground of the goods elevator cabin, and a first base for bearing the goods is slidably connected into the first groove; second grooves are formed in the positions, located on the left side and the right side of the first groove, of the ground of the goods elevator cabin, baffle assemblies capable of separating passengers from goods are slidably connected into the second grooves, first lifting devices for driving the baffle assemblies to ascend and descend are arranged in the second grooves, and a plurality of first shells are arranged on the inner circumferential wall of the goods elevator cabin in the circumferential direction at intervals; each first shell is internally provided with a first safety air bag, each first shell is provided with a first through hole facilitating popping of the first safety air bag, and the outer side wall of the goods elevator is provided with an automatic switch driving the first safety air bag to be opened.

Description

technical field [0001] The invention relates to the technical field of freight elevators, in particular to a freight elevator with high safety. Background technique [0002] In the current construction site and production workshop, the freight elevator is an indispensable transportation equipment. Although the freight elevator is regularly inspected every year, the failure rate of the freight elevator is still high. When a major failure occurs during the transportation of the goods carried by the freight elevator, and the freight elevator is in a state of free fall, if the freight elevator itself does not have any safety protection facilities, passengers will be easily injured or even killed. Even if the passengers are lucky enough not to be injured due to the failure of the freight elevator, they will still be bumped due to the displacement of the cargo, which greatly increases the probability of passenger injury. Therefore, there are still certain potential safety hazards...
