Abstract

The invention belongs to the technical field of railway vehicle equipment and relates to a sleeper power-driven lifting device for going to bed and getting out of bed. The sleeper power-driven lifting device comprises a stand column, a handle, a pedal device, a control device and a drive motor. A vertical lead screw is arranged in a guiding sliding groove in the stand column. The output end of the driving motor is connected with the lead screw, the handle is fixedly connected with a first lead screw nut, and the first lead screw nut is arranged on the lead screw in a sleeving mode. The pedal device is fixedly connected with a second lead screw nut, and the second lead screw nut is arranged on the lead screw in a sleeving mode and located below the first lead screw nut. The handle and the pedal device are arranged on the same side of the stand column. The control device comprises a control switch and a limiting switch. The control switch is arranged on the handle, and the limiting switch is arranged on the stand column. The control switch and the limiting switch are electrically connected with the driving motor. The sleeper power-driven lifting device is simple in structure and high in practicality and stability. The pedal device and the handle synchronously ascends and descends, a passenger can go to bed and get out of bed conveniently, fall accidents are avoided, and time and labor are saved when the passenger goes to bed and gets out of bed.

Description

technical field [0001] The invention belongs to the technical field of rail passenger car equipment, and specifically relates to an electric lifting device for upper and lower berths of a sleeper car. The pedal device and the handle are driven by a motor, which is convenient for passengers to get on and off the berths, and saves time and effort. Background technique [0002] At present, the train berths widely used at home and abroad are fixed pedals and handles, which require passengers to have good physical strength, which is not conducive to the elderly and weak to get on and off the berths. Risk of injury from a fall. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and seek to design a pedal device and a handle synchronously driven by a motor, which is convenient for passengers to get on and off the berth, and saves time and effort. [0004] In order to achieve the above object, the technical sc...
