Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a mobile platform device and method for erecting and docking large sections of a steel structure bridge. Background Art

[0002] At present, there are two main types of construction platforms for the erection and docking of large sections of steel structure bridges. The first is to rent an aerial work vehicle, such as a boom station, which is located on the highway bridge deck and then extends the boom to complete the highway bridge deck construction work on the boom vehicle platform; the second is to install a construction basket in advance as a construction platform when assembling large sections in the steel beam processing plant, and complete the highway bridge deck construction work in the basket after the bridge steel beam is hoisted into place.

[0003] At present, most of the steel structure bridges that are hoisted as a whole in segments have a girder height of about 14 meters. Common aerial vehicles are used to complete the construction of steel beam docking. Since the construction of steel beam docking is only a small part of the steel beam construction, if the machinery investment is too small, it will not be possible to carry out work on multiple work surfaces at the same time. If there is too much machinery investment, it will increase the economic cost. In addition, the operation of the machinery is more troublesome and requires professional training. If it is not operated properly, safety accidents are prone to occur. The second common method is to install the construction basket in the processing plant in advance. This method is due to the fact that most of the large-segment steel beam processing plants are far away from the steel beam installation site, and the turnover transportation distance is long, which increases the transportation cost. A large number of baskets need to be processed, and the risk of high-altitude demolition is relatively high. In summary, the existing construction methods have high safety risks and high costs. Summary of the invention

[0004] The purpose of the present invention is to solve the problems of the above-mentioned background technology and to propose a mobile platform device and method for the erection and docking construction of large sections of steel structure bridges.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A mobile construction platform device for erecting and docking large sections of a steel structure bridge comprises flanges protruding outward on both sides of the bridge, a support structure is movably arranged on the flange, a mobile construction platform is fixed to one side of the support structure, an electric telescopic upper and lower channel that can be vertically expanded is installed on the mobile construction platform, an electric telescopic mobile platform that can be horizontally expanded is installed at the tail end of the electric telescopic upper and lower channel, and the electric telescopic mobile platform after expansion is located below the flange.

[0007] As a further solution of the present invention: a counterweight is placed in the support structure.

[0008] As a further solution of the present invention: the moving wheel is an electric wheel.

[0009] As a further solution of the present invention: moving wheels are installed at the bottom of the supporting structure, and the moving wheels are used to drive the supporting structure to move on the flange.

[0010] As a further solution of the present invention: legs are rotatably connected to the bottom of the support structure near both sides of the moving wheel, and the two legs are limited and fixed by a detachable buckle rod.

[0011] As a further solution of the present invention: the electric telescopic mobile platform includes a driving member, the electric telescopic upper and lower channels are connected to the electric telescopic mobile platform in a straight line sliding manner through a limiting guide rail, a rack is fixed to the side of the electric telescopic mobile platform, the driving member is fixed on the electric telescopic upper and lower channels, and the gear at the output end of the driving member is meshed with the rack.

[0012] As a further solution of the present invention: an electric power control system is also arranged in the supporting structure.

[0013] An operation method of a mobile platform for erecting and docking large sections of a steel structure bridge comprises the following steps:

[0014] Step 1: Control the moving wheels to move the construction mobile platform to the construction position of the steel beam interface of the bridge;

[0015] Step 2: Control the electric telescopic upper and lower channels to adjust their own height;

[0016] Step 3: Control the electric telescopic mobile platform to the construction location, brake the mobile wheels, support the construction mobile platform through the outriggers to keep it in working condition, turn off the power control system, and the personnel use the electric telescopic mobile platform to the construction location for construction;

[0017] Step 4: After the construction is completed, retract the electric telescopic mobile platform, retract the upper and lower channels and the outriggers, release the brakes of the moving wheels, and control the moving wheels to move the mobile construction platform to the next steel beam interface construction position.

[0018] The beneficial effects of the present invention are as follows: the main structure of the mobile platform is constructed by welding steel sections, and electric directional wheels, electric telescopic channels, and electric telescopic platforms are configured, counterweights are installed, and the platform's movement and telescopic adaptation to the corresponding construction position are controlled by an electric control system, which effectively solves the technical difficulties in the construction of large-section integrally hoisted steel structure bridges due to the high construction working surface of the docking interface, the difficulty in installing the docking interface construction platform, and the high risk of mechanical construction. The risk of large-section erection and docking construction of steel structure bridges is controllable, and the quality of steel beam installation is guaranteed. Therefore, the technical solution of the mobile platform for the erection and docking construction of large-section steel structure bridges of this application reduces the risk of large-section erection and docking construction of steel structure bridges, reduces the difficulty of construction, saves construction costs, and ensures the safety and quality of engineering construction.
