Abstract
Description
Technical Field
[0001] The utility model relates to the field of products related to electrical construction, in particular to a pipeline elbow prefabrication device for electrical pre-buried construction in a wind farm. Background Art
[0002] Electrical engineering is an important sub-project of wind farm installation engineering. Its success or failure is related to the progress, acceptance and use of the entire single project. Compared with other industrial electrical installation and civil electrical installation projects, wind farm electrical construction has some characteristics: wind farms are mostly located in wild places such as the seaside, grasslands, hills, and Gobi. The conditions are difficult and the environment is harsh, which brings many inconveniences to the construction. The foundation of the wind turbine is usually a large concrete block foundation. There are usually many pre-buried wire pipes for electrical instruments in the foundation. Generally, steel wire pipes are used, and the right-angle joints of the wire pipes generally use elbows with larger arcs. This requires staff to pre-bend the ends of the wire pipes in advance. The main working principle of the electric pipe bender is to use the power output by the motor to drive the wheels, thereby driving the bending mold and the pipe to rotate and deform. Under the action of the bending mold, the pipe rotates and deforms along the contour line of the bending mold, thereby achieving the purpose of bending;
[0003] However, the existing electric pipe bending machines need to heat the pipes when prefabricating the elbows. When the heated pipes are bent, the surface will oxidize and break into pieces. These pieces are difficult to clean and easily accumulate, making subsequent elbow operations complicated and defective. Utility Model Content
