Abstract

The invention belongs to the technical field of rail transit equipment, and particularly relates to a through passage gangway foot plate device which structurally comprises a gangway foot plate body, abrasion parts, mounting grooves, a locking self-clamping mechanism, an observation opening and an observation opening cover plate, and the abrasion parts are arranged on the two longitudinal side edges of the lower surface of the gangway foot plate body; the mounting groove is arranged on the longitudinal central axis of the lower surface of the gangway foot plate body; the locking self-clamping mechanism is arranged in the mounting groove; the observation opening is formed in the upper portion of the locking self-clamping mechanism; the observation opening cover plate is arranged on the observation opening, and the gangway foot plate body can be rapidly mounted and dismounted through the locking self-clamping mechanism; pull rings are pulled to the sides, provided with protrusions, of limiting pull rods to be limited simultaneously or independently, so the protrusions of the limiting pull rods are clamped at the end parts of the mounting grooves, at the moment, the limiting pull rods are in a clamping state, the gangway foot plate is unlocked, and when one pull ring is independently pulled, the other pull ring also needs to be subjected to the same operation, so that the gangway foot plate can be unlocked.

Description

Technical field: [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a passage board device, which can improve the efficiency of disassembly and installation and ensure driving safety. Background technique: [0002] Passageway is an important common part of rail vehicles, used to connect two adjacent carriages, so that passengers can pass or stay safely, and feel safe and comfortable. During the operation of the rail vehicle, the passage needs to meet the requirements of the rail vehicle passing the curve. Among the three panels of the passage, the one in the middle is called the transition plate, and the two sides are pedals. The transition plate and the pedal are overlapped together. The connecting rod mechanism of the crossing board makes the crossing board lock in the middle position of the two pedals. The sheet type crossing board is a common structural form in through-channel products, which can realize various fu...
