Description
[ field of technology ]
The utility model belongs to the technical field of power transmission and distribution equipment, and particularly relates to a tubular busbar hoisting bracket special for a wind power stepped concrete tower.
[ background Art ]
The concrete tower has various structures, one of the concrete tower is in a stepped shape, the hoisting and the installation of the integrated tubular bus are required to be extremely high, the hoisting technology is difficult, the concrete tower is mainly characterized in that the lower part of the concrete tower is large in diameter, the upper part of the concrete tower is small in diameter, the radial shape of the outer wall of the inner wall is in a stepped shape, and the radial steps are fluctuated and the radial step difference is relatively large; in addition, the inner cavity parts are numerous, and the inner cavity parts are provided with a plurality of special-shaped brackets such as a cat ladder, a steel angle rib, a lamp bracket, a platform and the like, so that the occupied space is large, the effective space is small, and under the normal hoisting condition, the hoisting is more difficult to be carried out towards the upper part of the tower, because the diameter of the tower is smaller towards the upper part, and the inner space is narrower. When the tubular bus is hung from the outside of the concrete tower to the inside of the concrete tower, the upper space of the tower is narrow, so that the tubular bus is difficult to be even incapable of being hung. In addition, the upper part of the concrete tower is small in space and higher in height, and if the length of the tubular bus bar is about 20 meters when the height of the concrete tower is about 180 meters, the requirement on the suspension arm of the crane is definitely longer, the requirement on crane technicians is high and the cost is higher. Meanwhile, the suspension wall of the required crane is longer, an external hoisting personnel is difficult to know the hoisting position of the accurate internal tubular bus, the hoisting personnel is difficult to effectively control and operate the hoisting position, the tubular bus, the tower and other devices in the tower are likely to collide in the hoisting process, and then damage triggering accidents are caused. In terms of personnel, if the concrete tower is directly hoisted according to the scheme, the personnel for installing the tubular bus inside the concrete tower can be at great life safety risk.
Therefore, in order to solve the lifting difficulty of the integral tubular bus of the stepped concrete tower, an effective and feasible lifting scheme is adopted, namely, a secondary lifting scheme is adopted, when the concrete tower is lifted to the position with the height of 20 meters, all (5 to 6 sections) integral tubular buses are lifted at the bottom of the concrete tower with larger inner cavity space, after the concrete tower is lifted, the process of lifting the integral tubular bus from the bottom of the tower to the corresponding mounting bracket on the wall of the tower is carried out, and the lifting scheme effectively solves the technical problems that the stepped tower is difficult to lift due to the narrow upper space and high height.
However, the problem of stacking and fixing the integral tubular bus at the bottom of the tower barrel still needs to be further solved in the lifting scheme, otherwise, the lifting scheme cannot be implemented, and because the integral tubular bus is longer in length, more in number and heavier in weight, in the lifting process, a bracket capable of safely and reasonably stacking the 5-6 sections of integral tubular bus is lacking, and the tower barrel can be conveniently and simply withdrawn after the integral tubular bus is installed on the tower barrel wall.
