A mobile device for bridge inspection and reinforcement

Abstract

The invention discloses a mobile device for detecting and fastening a bridge. The mobile device comprises a first supporting plate and a workbench, wherein a mounting shell is arranged at the top end of the first supporting plate; two first rotating shafts are symmetrically arranged in the mounting shell; a plurality of winding reels are arranged on each first rotating shaft; lifting ropes are respectively arranged on the winding reels; each lifting rope goes around a first fixed pulley and a second fixed pulley successively and then penetrates through a vertical rod; a supporting rod is arranged at one end, away from each winding reel, of the corresponding lifting rope; the lifting ropes on two sides are driven by a motor to ascend and descend synchronously; and the workbench comprises a plurality of splice plates. The mobile device disclosed by the invention has the beneficial effects that the workbench comprises the splice plates, so that the splice plates can be spliced according to the width of the bridge in operation; and the lifting ropes on two sides can be driven to ascend and descend synchronously to guarantee that the workbench can be lifted in a horizontal state.

Description

technical field [0001] The invention mainly relates to the field of bridge engineering, in particular to a mobile device for bridge detection and reinforcement. Background technique [0002] With the passage of time, bridges and viaducts will enter the aging stage, and there will be cracks and water seepage on the bottom surface. For bridges that still have bearing capacity to be directly demolished and rebuilt, not only the cost is high, but also resources will be wasted. Only basic maintenance and reinforcement are needed. It can be reused. Most of the existing bridge maintenance tools and working platforms are a whole. They are large in size and difficult to move and transport, and the length and width are fixed. They cannot be well adapted to bridges and viaducts of different widths. It is also difficult to keep the working platform in a horizontal state for lifting. If an unexpected situation occurs in the lifting process and the working platform is greatly inclined, it...

[0002] With the passage of time, bridges and viaducts will enter the aging stage, and there will be cracks and water seepage on the bottom surface. For bridges that still have bearing capacity to be directly demolished and rebuilt, not only the cost is high, but also resources will be wasted. Only basic maintenance and reinforcement are needed. It can be reused. Most of the existing bridge maintenance tools and working platforms are a whole. They are large in size and difficult to move and transport, and the length and width are fixed. They cannot be well adapted to bridges and viaducts of different widths. It is also difficult to keep the working platform in a horizontal state for lifting. If there is an unexpected situation in the lifting process that causes the working platform to tilt greatly, it will bring hidden dangers to the personal safety of the staff standing on it.
