A device for bridge inspection vehicles to pass through bridge pier cover beams

Abstract

The invention discloses a device for facilitating a bridge detection vehicle to pass through a cover beam of a bridge pier. The device is characterized by comprising a transition orbit (6), a front lifting orbit (3), a rear lifting orbit (7) and an orbit lifting mechanism, wherein the transition orbit (6) is fixedly arranged below a cover beam requiring a detection vehicle to pass through along the extension direction of a bridge; the front lifting orbit (3) is arranged in front of the vehicle coming direction of the transition orbit (6) and can move between a descending position smoothly connected with the transition orbit (6) and an ascending position smoothly connected with a detection vehicle travelling orbit; the rear lifting orbit (7) is arranged at the rear of the vehicle coming direction of the transition orbit (6) and can move between the descending position smoothly connected with the transition orbit (6) and the ascending position smoothly connected with the detection vehicle travelling orbit; and the orbit lifting mechanism is used for lifting the front lifting orbit (3) and the rear lifting orbit (7) between the ascending position and the descending position. According to the technical scheme, the detection vehicle can successfully pass through the cover beam of the bridge pier, and the detection task of the whole bridge can be finished by using the one detection vehicle, so that the amount of the detection vehicle is reduced.

Description

technical field [0001] The invention relates to a vehicle track obstacle avoidance device, in particular to a device suitable for a bridge detection vehicle passing through bridge structure obstacles. Background technique [0002] At present, the bridge inspection vehicle has become an indispensable equipment for daily maintenance and repair of large bridges, especially steel structure bridges. Existing bridge inspection vehicles mainly include vehicle-mounted walking type and track walking type. Among them, the vehicle-mounted walking bridge inspection vehicle is moved by a vehicle that can walk on the bridge surface. Its advantage is that it can walk flexibly and can inspect different bridges according to needs. However, its disadvantage is that it forms obstacles on the bridge and affects the passage of vehicles on the bridge, so its operating time is greatly limited. The track-type bridge inspection vehicle is installed on the special walking track under the bridge. Al...
