Embodiment Construction

[0023] see figure 1 , a port connection device provided by an embodiment of the present invention is used to connect two segments 1 , and the port connection device includes: an anchor box part 2 , two lug plate assemblies 3 and several adjustment pads 4 .

[0024] The two ear plate assemblies 3 correspond to the two segments 1 one by one, and the ear plate assemblies 3 are fixedly arranged on the corresponding segments 1 .

[0025] Both ends of the anchor box part 2 are respectively rotatably connected to two ear plate assemblies 3 .

[0026] Several adjusting pads 4 are detachably arranged between the anchor box part 2 and the two segments 1 .

[0027] Specific Embodiments of the Application Due to the one-to-one correspondence between the two ear plate assemblies 3 and the two segments 1, the ear plate assemblies 3 are fixedly arranged on the corresponding segments 1, and the two ends of the anchor box part 2 are rotatably connected to the two segments 1 respectively. The...

Abstract

The invention discloses a method for using a port connection device, which belongs to the technical field of bridges. The method of using the port connection device includes: arranging the two lug assemblies on the two sections in one-to-one correspondence; connecting the connecting rings at both ends of the box body to the corresponding lug assemblies in a rotatable manner; inserting the adjusting pad into the Between the anchor box part and the two segments. The port connection device of the invention can not only complete the on-site installation and connection of steel truss suspension bridge segments, but also satisfy the alignment adjustment of the bridge.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a method for using a port connection device. Background technique [0002] Steel truss girder suspension bridges are increasingly used in large-span and mountainous environments, and the on-site installation of steel truss girder segments is mainly carried out by cable cranes. Since the on-site installation of the suspension bridge is to weld (or bolt) the segments after all the segments are installed and the alignment meets the requirements, the steel truss girder segments need to be temporarily connected during the hoisting process. [0003] When the segment is hoisted in place and the permanent sling is connected to the segment, the segment only bears the force in the vertical direction at this time, and it is necessary to temporarily connect the segment to be installed with the installed segment, that is, the segment is re-installed. Adding the horizontal force along the lon...
