Description

Technical Field

[0001] The invention relates to the technical field of manned rail vehicles, and in particular to a telescopic, portable and lightweight electric manned rail vehicle. Background Art

[0002] Railcars (including trailers, the same below) are the main means of transportation for railway equipment maintenance, overhaul, infrastructure and other construction departments to perform tasks. Railcars are divided into heavy and light types. Railcars that can be evacuated from the line at any time by passengers are called light railcars; railcars that cannot be evacuated from the line at any time by passengers are called heavy railcars. Under normal circumstances, maintenance workers often need to walk to the maintenance point when going to the maintenance point, which takes a long time, consumes a lot of physical energy of maintenance workers, and greatly reduces the effective working time. General railcars are large in size and are only single-person vehicles, and it is not easy to change lanes and move. To this end, the present invention proposes a telescopic portable lightweight electric manned railcar to solve the above problems. Summary of the invention

[0003] The object of the present invention is to provide a telescopic portable lightweight electric manned rail vehicle to solve the problems raised in the above background technology.

After the use of the device, the grip bar can be rotated through the first rotating shaft to make it close to the surface of the limiting plate. For the seat cushion, the second rotating shaft is used to make it close, which greatly facilitates the operator to use when the device is folded and unfolded.

[0013] 2. Using the support plate, when the rail vehicle is moved out of the track, the operator can pull out the shoulder strap so that the hook at the left end of the shoulder strap passes over the shoulder and connects with the buckle, so that the rail vehicle can be carried on the back. During normal use, the sliding button is moved to fix it to the inside of the card slot to enhance the safety of the device.

[0014] 3. Using the telescopic device, after the rail car is used, the operator moves it off the track and pushes it to one side.
