Abstract

The invention discloses a movable type straddle single-track boarding ladder system. The movable type straddle single-track boarding ladder system comprises a frame (1), a plurality of walking wheels(3) are symmetrically arranged on the inner side of the bottom of the frame (1), a fixed track (6) parallel to a straddle single-track track is arranged below the frame (1), and a row of fixing holesare arranged on the fixed track (6) at intervals. A guide wheel (2) is fixedly arranged at the bottom of the frame (1), the guide wheel (2) is arranged on the fixed track (6), wedge-shaped baffle blocks (4) are symmetrically arranged at two sides of the guide wheel (2), and through holes are formed in the wedge-shaped baffle blocks (4). The spacing of the through holes of the wedge-shaped baffle blocks (4) on the two sides is the same as the distance between adjacent fixing holes, and the though holes and the fixing holes are provided with fixed pins (5). According to the movable type straddlesingle-track boarding ladder system, the guide wheel and the walking wheels can drive a boarding ladder to move along the track, and the guide wheel locks independently to fix the boarding ladder oncar doors of vehicles of different trainlengths.

Description

technical field [0001] The invention belongs to the technical field of maintenance tooling for urban rail transit vehicles, and more specifically relates to a mobile straddle monorail boarding ladder system. Background technique [0002] The straddle rail transit system is a form of urban rail transit system. It is supported, guided and stabilized by a single rail beam. The vehicle body rides on the rail beam and the distance between the vehicle floor and the ground is usually 2 to 3m. about. When the vehicle receives and receives the vehicle in the morning and evening, the drivers and passengers need to use the boarding ladder to get on and off the vehicle. [0003] As an important auxiliary boarding component, the boarding ladder is usually designed as a fixed type to meet the normal boarding needs of drivers or commissioning personnel during use, and is installed at the door of the driver's cab according to the limit requirements of different models. On the side ground,...
