Problems solved by technology

The entire track installation needs to be on the construction work platform under the beam, combined with lifting, climbing and other equipment for installation; if there is no construction work platform at the bottom of the beam or the cost of building a platform is high, such as in unnavigable waters, across deep canyons, There is no trestle or the space of the trestle is limited, etc. It is very inconvenient to install the track, including welding, bolting, lifting, etc.

Abstract

The invention discloses a method for installing a track of a bridge steel girder maintenance car. The method comprises the following steps: installing a first section of maintenance car track beam; a maintenance car prefabricated in advance is hoisted into and installed at the bottom of the bridge steel main beam in an inverted hanging mode, and a second section of maintenance car track beam and a connecting base are hoisted into the maintenance car; the maintenance car is controlled to move to the front end of the installed first section of maintenance car track beam, and the second section of maintenance car track beam is pulled up to the preset installation height; fixedly connecting the second section of maintenance car track beam with the connecting seat; the connecting base is welded to the bottom of the bridge steel girder, and then the maintenance car is controlled to continue to move forwards till the front end of the first maintenance car track beam is connected with the tail end of the second maintenance car track beam; and the steps are repeated until all the maintenance car track beams are installed. The method is reliable in process and convenient to operate, the problem about installation of the steel girder maintenance car track when the operation platform at the bridge site is limited is solved, large-range erection of the construction operation platform is avoided, and the cost for mounting and dismounting the support is saved.

Description

technical field [0001] The invention relates to the field of rail installation of a bridge steel main girder maintenance vehicle. More specifically, the present invention relates to a method for installing a rail of a bridge steel main girder maintenance vehicle. Background technique [0002] The bridge steel main girder maintenance vehicle is mainly used to carry out comprehensive inspection and maintenance of each structure of the bridge main girder to ensure the safety of the bridge. The entire track installation needs to be installed on the construction work platform under the beam, combined with equipment such as lifting and climbing; In the absence of a trestle or with limited space for the trestle, the track installation operations including welding, bolting, and lifting are very inconvenient. SUMMARY OF THE INVENTION [0003] In order to achieve these objects and other advantages according to the present invention, a method for installing a bridge steel main beam...
