This trolley adopts a modular structural design and can be assembled and built on the construction site to adapt to different types of bridges. It also uses a wheeled walking mechanism to support the top of the bridge deck to achieve walking. At the same time, an outrigger truss structure is used to extend the construction basket to the bottom of the bridge so that the installers can complete the installation of the bridge drainage pipe at the bottom of the bridge top plate, ensuring construction safety, improving construction efficiency, and reducing construction costs. In the specific use process, the truss frame structure 4 is assembled on site, and is set on the top of the bridge deck 2 by hoisting, and the installation basket 15 is adjusted according to the construction position. After the installation of the basket 15 is completed, the operator goes from the personnel passage 12 to the basket 15 to install the corresponding bridge drainage pipe.

[0037] Working process and principle of this utility model:

[0038] First, when it is necessary to install the main drainage pipe 11 of the bridge under the bridge deck 2, the truss frame structure 4 is assembled and welded on site according to the actual construction position and the specific size of the bridge deck. After the truss frame structure 4 is installed, the corresponding personnel passage 12 is installed. After the installation of the personnel passage 12 is completed, the hanging basket 15 is arranged and installed, and the position of the hanging basket 15 is adjusted, and then the counterweight sandbags 6 are placed, wherein the counterweight sandbags 6 are weighed more than 1.5t and are stacked close to the inner side of the bridge. Two steel wire ropes are added to the hanging basket working platform, and the steel wire ropes are suspended on the upper truss frame structure 4 to increase safety. The lower working platform is a detachable structure, which is convenient for hanging basket hoisting. When the wind force reaches level 5 or above, construction is prohibited; finally, the operating personnel go up to the hanging basket 15 through the personnel passage 12, and install the main drainage pipe 11 of the bridge on the hanging basket 15;

[0039] It is strictly forbidden to stand when the hanging basket is moving. When lifting and moving, remove the extra sandbags on the outside to press the weight, and keep 100Kg of counterweight on each truss before moving. Use [20 channel steel as a shoulder beam for lifting. Find the balance point in advance before lifting, and only after the balance point is fixed can the lifting operation be carried out. A dedicated person must be assigned to direct the lifting operation. The lifting point uses a buckle to fix the wire rope on the longitudinal channel steel.
