Abstract
The utility model relates to a connection structure of a cross arm and a pole tower. The connection structure of the cross arm and the pole tower comprises the pole tower and the cross arm connected with the pole tower. The cross arm is installed on the pole tower through a base. The base comprises a cylindrical seat tube, one end of the seat tube is fixedly connected on the outer wall of the pole tower, and a flange plate is arranged at the other end of the seat base. The connection end of the cross arm is connected with the flange plate in a matched mode. Due to the facts that the base is installed on the pole tower, the base comprises the cylindrical seat tube, and the shape of the opening of the cylindrical seat tube is easily controlled and obtained, the seat tube can be firmly welded on the pole tower, the welding position is not prone to cracking, badness including cracking and the like can not happen after the seat tube is used for a long time, and the service life is prolonged. The flange plate is arranged on the outer side of the seat tube, so that the cross arm is conveniently connected with the seat tube and the connection is more convenient. The connection structure of the cross arm and the pole tower has the advantages of being firm in connection and long in service life.
Description
Technical field
The utility model belongs to the electric power tower technical field, relate in particular to a kind ofly be connected firmly, the cross-arm of long service life and the syndeton of shaft tower.
Background technology
Along with China was to the input increasing of power infrastructures in recent years, increasing transmission line of electricity is set up.Shaft tower because of its compare with traditional angle steel tower have specious, floor space is little, cost performance is high, and adopted by vast Construction unit.Cross arm of tower is the important component part of shaft tower, it plays the effect of attached cable, present cross arm of tower all adopts polygon steel control, because the opening shape of polygonal steel pipe is wayward and obtain, therefore cross-arm is difficult to directly be welded on the outer wall of shaft tower, and also to exist weld on the outer wall of shaft tower insecure even be welded on, and the bad phenomenon such as sealing-off very easily appear in weld after the use of short time, application life is very short, exists very large potential safety hazard.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and provide a kind of and be connected firmly, the cross-arm of long service life and the syndeton of shaft tower.
The purpose of this utility model is achieved in that the syndeton of a kind of cross-arm and shaft tower, comprise shaft tower and the cross-arm that is connected with shaft tower, described cross-arm is installed on the shaft tower by pedestal, pedestal comprises columniform seat pipe, one end of seat pipe is fixedly connected on the shaft tower outer wall, the other end is provided with flange, and link and the flange of cross-arm are connected.
Described seat pipe is provided with the stiffened panel that the casing pipe is connected with shaft tower with the angle of shaft tower.
Described seat pipe is fixed on the outer wall of shaft tower by the mode of welding.
The utlity model has following positive effect: cross-arm of the present utility model is installed on the shaft tower by pedestal, pedestal comprises columniform seat pipe, the opening shape of columniform seat pipe is easy to control and obtain, can very firmly be welded on the shaft tower, and weld is not easy to crack, it is bad that cracking etc. can not appear in long-time use, prolonged application life; The arranged outside flange of seat pipe is convenient to cross-arm and seat being connected of pipe like this, makes connection more convenient; The seat pipe arranges stiffened panel with the angle of shaft tower, has reinforced the bonding strength of seat pipe with shaft tower, makes the seat pipe more sturdy and durable with being connected of shaft tower.
