Improved boarding bridge

Abstract

The invention relates to an improved boarding bridge. The improved boarding bridge comprises a movable channel which consists of an inner movable channel, a middle movable channel and an outer movable channel in sliding fit; the inner side of an inner guide rail is provided with an inner inversed U-shaped groove; the outer side of an outer guide rail is provided with an outer inversed U-shaped groove; an idle wheel is matched with the inner inversed U-shaped groove and the outer inversed U-shaped groove; the improved boarding bridge also comprises a plurality of covering devices for covering the inner inversed U-shaped grooves of the inner guide rails on the inner bottoms of the middle movable channel and the outer movable channel; each covering device consists of a fixed plate, a curtain sheet, a torsional spring and a bent decorative baffle; the curtain sheet is connected to the fixed plate through a pivot; the torsional spring is matched with the curtain sheet and the fixed plate; a horizontal plate of the bent decorative baffle is fixedly connected with the top of the fixed plate; the fixed plate is fixed on the upper part of the inner inversed U-shaped grove; and curtain sheets of two adjacent covering devices are staggered by the thickness of one curtain sheet in the horizontal direction. As the structure is adopted, the improved boarding bridge prevents the bareness of the inner guide rail and the idle wheel and removes potential safety hazards.

Description

technical field [0001] The invention relates to a boarding bridge. Background technique [0002] In the current prior art, a boarding bridge includes a column, a rotating platform, a movable channel, a port system, a lifting system, a driving device and a service ladder, and the movable channel is composed of inner, middle and outer movable channels slidingly fitted; , The guide rails of the middle and outer passages are made of angle steel, the bottom rollers and angle steel guide rails of the inner movable passage are rollingly matched with the bottom angle steel guide rails and bottom rollers of the middle movable passage respectively, and the bottom rollers and angle steel guide rails of the middle movable passage are respectively connected with the outer movable passage The bottom angle steel guide rail and the bottom roller are used for rolling cooperation, and the rollers on the top of the middle and outer movable passages are respectively rolling and matched with the...
