Abstract

The invention provides an elevator. The elevator comprises an upper elevator frame and a lower elevator frame, wherein the bottom of the upper elevator frame is pivotally connected with the top of the lower elevator frame, and a connecting and limiting device which is used for connecting, locking and limiting the upper elevator frame and the lower elevator frame after the upper elevator frame and the lower elevator frame are unfolded is arranged at the joint. The elevator provided by the invention has the advantages that the overall size is reduced through folding, and the elevator is easy to store and carry.

Description

technical field [0001] The invention relates to the technical field of lifts, in particular to a foldable lift. Background technique [0002] With the rapid development of my country's rail transit industry, high-speed EMUs not only solve the capacity and power for the country, relieve the pressure on transportation, but also shorten people's travel time and provide convenient services for passengers. During the operation of the EMU, various emergency temporary parking may occur, and all personnel on the vehicle need to get off temporarily, or after the vehicle is put into storage, workers need to enter and exit the vehicle during daily maintenance. Therefore, in order to ensure the transportation of the vehicle To ensure the effective connection and connection of maintenance safety and ground service facilities, high-speed EMUs are usually equipped with elevators, which provide guarantee and convenience for solving such problems. It can be put into service in the operating...
