Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
referring to fig. 1 to 3, an operation platform for constructing a cable of a main tower 1 of a cable-stayed bridge includes: the beam frame is fixedly connected with the top surface of the main tower 1;
the vertical beams 4 are fixedly connected to the beam frame;
the annular platforms 7 are fixed between the vertical beams 4, a square hole for allowing the main tower 1 to pass through is formed in the middle of each annular platform 7, the annular platforms 7 are uniformly arranged from top to bottom, and a grid part is fixed on the edge of each annular platform 7;
and the climbing mechanisms are fixed between every two adjacent annular platforms 7.
The construction operation platform is firstly assembled, after the construction platform is assembled, the construction platform is hoisted by a hoisting tool and then passes through the main tower 1 of the cable-stayed bridge, wherein the middle part of the annular platform 7 is provided with a square hole, so that the construction platform can be limited to only move up and down, and finally is fixedly connected with the top surface of the main tower 1 by a beam frame, after the construction operation platform is assembled on the main tower 1, an operator can construct the stay cable 10, specifically, the operator stands on the annular platform 7 to construct, the stay cable 10 is positioned between the two annular platforms 7, so the construction is not influenced, after the stay cable 10 of one layer is assembled, the operator moves downwards or upwards by the climbing mechanism to construct the stay cable 10 of the other layer, because the annular platform 7 is adopted, therefore, the movement space of an operator is larger, the safety is better during construction, and the safety of the operation platform can be further improved by the grid stopping part at the edge of the annular platform 7.
