The utility model can also adopt the following technical measures:

The positioning support structure includes a bracket fixed on the horizontal guardrail of the hanging basket, a swing rod with a handle hinged at one end of the bracket, a connecting plate hinged with the other end of the swing rod, and a push rod hinged with the other end of the connecting plate.

The positioning support structure includes a screw sleeve fixed on the horizontal guardrail of the hanging basket, a screw rod is equipped in the screw sleeve, and a rotating handle is connected to the end of the screw rod in the hanging basket.

The advantages and positive effects of the utility model are: because the utility model adopts the above-mentioned technical scheme, that is, the construction platform mainly utilizes the structural characteristics of the bridge girder for design, and fully utilizes the space and components available in the high altitude. The utility model uses the upper surface of the main girder as the walking surface, and the upper eaves of the main girder as the limiting surface, so as to ensure that the construction platform can walk on the main girder stably, and does not need other traction and driving devices. The actual work station can be moved by itself, and it is labor-saving. After sliding to the designated position, the working platform and the main beam are locked and positioned by the positioning support structure, so as to avoid the construction platform due to non-human movement during the actual construction process. The construction platform has the advantages of convenient assembly and disassembly, flexible movement, safety and reliability, convenient operation, low cost and strong practicability.

Detailed ways

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Figure 1, a convenient mobile construction platform for bridge construction, including a walking platform 1, hanging baskets 2 are mounted symmetrically on both sides of the walking platform, and a walking wheel set 3 is provided on the lower surface of the walking platform. Two L-shaped connecting plates 4 are fixed on the lower surface of the walking platform, and the two L-shaped connecting plates are installed symmetrically; a limit-limited wheel set 5 is installed on it, and the upper surface of the limit-limited wheel set and the main beam 6 The upper eaves 6-1 fit together; the hanging basket is provided with a climbing ladder 2-1. Although this climbing ladder is a known technology, its safety on the construction platform is relatively prominent; and it is convenient for operators to go up or down; Rigid guardrails 2-2 are arranged around the hanging basket, and protective nets 2-4 are bound on the guardrails. The protective nets serve as the second line of defense, further improving the safety protection performance, and at the same time giving the operator psychological protection. A sense of security; the bottom of the hanging basket is fixed with a rigid pedal 2-3, and the upper surface of the rigid pedal is provided with anti-slip lines, and the design of the anti-slip lines has further improved the safety of the operator; the hanging basket A positioning support mechanism 7 to prevent the construction platform from moving and swinging is provided between the main beam.
