Guide beam walking type bridge detection and rescue work vehicle

Abstract

The invention discloses a guide beam walking type bridge detection and rescue work vehicle which is composed of a guide beam, a motor vehicle, a detection vehicle and a rescue vehicle. The guide beam walking type bridge detection and rescue work vehicle works under bridges. The detection vehicle and the rescue vehicle are respectively of a multi-level truss structure, and can be contracted and rotationally folded under the action of a hydrocylinder, and a lifting device is arranged inside the truss of the rescue vehicle. The detection vehicle and the rescue vehicle on the guide beam are completely contracted and folded when passing through a bridge pier, and the maximum cross sectional dimension of the detection vehicle and the rescue vehicle is within 1.1m*1.1m. On the working condition of bridge detection, the rescue vehicle is completely contracted and folded, the detection vehicle is partly unfolded, and a work platform used for bridge detection is provided. On the working condition of rescue, the detection vehicle and the rescue vehicle are completely unfolded, a door frame structure is connected to the two sides of the bridge pier in an overlapped mode, and at the moment, a winch on the rescue vehicle is located in the middle of the door frame and can conduct lifting rescue operation. The guide beam walking type bridge detection and rescue work vehicle has the functions of loading, bridge detection and lifting rescue, automatically provides power, has the capability of passing through the bridge pier, is wide in detection range, can be applied to daily maintenance work of the bridge conveniently and effectively, and can also be used as a device for railway accident emergency rescue.

Description

technical field [0001] The invention relates to equipment for bridge detection and accident rescue, in particular to a bridge detection and rescue operation vehicle of the guide beam walking type, which integrates bridge detection operation functions and high-speed railway accident rescue functions. Background technique [0002] my country's high-speed railway has the characteristics of a large proportion of bridges and many viaducts and long bridges. With the increase of bridge service time, the bridge structure will inevitably have natural aging, damage accumulation and other diseases, which will affect the safety of railway traffic. Since the pedestrian passages on both sides of the new high-speed railway viaducts have been cancelled, the original bridge inspection equipment that relies on pedestrian passages has lost its usefulness. In addition, the original bridge inspection equipment occupies a large boundary space, and the occupied skylight time is too long, which af...

Problems solved by technology

With the increase of bridge service time, the bridge structure will inevitably have natural aging, damage accumulation and other diseases, which will affect the safety of railway traffic

Since the pedestrian passages on both sides of the new high-speed railway viaducts have been cancelled, the original bridge inspection equipment that relies on pedestrian passages has lost its usefulness

In addition, the original bridge inspection equipment occupies a large space and takes too long time for the skylight, which affects the operation of other types of work and brings great difficulties to bridge maintenance.

When an emergency occurs on a high-speed railway, it is often difficult to rescue because the bridge is far away from the ground, so there is an urgent need for rescue equipment with the function of establishing an emergency channel between the viaduct deck and the ground to transport personnel and materials
