Description

A special combination tensioning device for prestressed electric poles

technical field

The invention relates to a special combination tensioning device for prestressed electric poles, in particular to a special combination tensioning device applied to the steel bar skeleton of a conical electric pole.

Background technique

The existing prestressed electric pole tensioning device is mainly composed of a steel circular rib plate and an anchor plate with a threaded secondary structure and a flange type rib plate. The disadvantage is: when stretching the conical pole steel frame, if the reinforcement on different sides is not uniformly stressed, the whole steel frame will be deflected by the lateral thrust, which will affect the roundness of the steel frame if it is light, and the heavy side would cause a safety accident.

Contents of the invention

The technical problem to be solved by the utility model is to provide a special combination tensioning device for prestressed poles, which can effectively overcome the deflection of the conical steel frame due to the asynchronous force during the stretching process. The problem.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a special combination tensioning device for prestressed electric poles includes a base, and a rib plate, a positioning plate, a rib plate, and a rib plate arranged on the base Welded on the base, the two ends of the longitudinal main ribs are respectively set on the positioning plate and the hanging rib plate, the longitudinal main ribs pass through the end of the positioning plate and are fixed on the rib plate through the clamp, and the rib plate is connected to the tensioning machine through the connecting piece;

The base is provided with a plurality of sliding slots and positioning slots, and the positioning plate is inserted into the positioning slots to be connected to the base. A sliding bar is arranged in the sliding slot along the longitudinal direction of the base, and the fixed sleeve passing through the lower end of the tendon plate is sleeved on the sliding bar.

Furthermore, the base is provided with a longitudinal positioning groove.

Further speaking, a cylindrical body is provided in the center of the piercing rib plate, opposite piercing process holes are provided on the side wall of the cylindrical body, and four protruding teeth are provided on the non-connecting edge of the cylindrical body; the connecting piece is an open box Three holes are arranged along the center line of the long axis of the open box body. The middle hole corresponds to the four-teeth convex four-teeth hole and the four-teeth concave hole on both sides of the rib plate. The holes on both sides are positioning holes. In the open box body The short axis is provided with tension holes that pass through.

The utility model has the advantage that the rib plate, the positioning plate, and the rib plate are integrated into a whole through the base, and when the steel bar frame of the conical electric pole is stretched, the base can resist the side of the steel bar frame when the out-of-synchronization time is very short. When the force is not synchronized for a long time, and the base is also slightly deformed by the lateral thrust, the sliding rod keeps the displacement direction of the rib plate in the same direction, so that the conical pole steel skeleton can be different by increasing the tension. The steel skeleton on the side is evenly stressed.
