Power line tower ventilation pipe fastening device

technical field

The invention relates to a ventilation pipe fastening device, in particular to a power line tower ventilation pipe fastening device.

Background technique

At present, the commonly used ventilation pipe fastening device is composed of U-shaped hoops, bolts and nuts. Due to the special structure of the angle steel tower and the high distance from the ground, it is difficult to install and use this ventilation pipe fastening method on the angle steel tower. Although some fastening devices have also been contributed in the prior art, such as the fastening form of the left and right half hoop bodies, etc., there are still many parts that need to be assembled and used, the structure is complicated and the cost is high, the installation and use are cumbersome, and it is inconvenient to work at heights , unsatisfactory work performance and other technical defects. The authorized announcement number is CN203273014U patent "communication base station angle steel tower ventilation pipe fastening device" has improved the ventilation pipe fastening device for angle steel tower, but there is still the problem of inconvenient screwing in of nuts. Moreover, the fastening device of this technology does not have a fixed clamping structure with the angle steel. After a long time of use, the U-shaped bayonet and the bolt connection become loose. Under the action of wind force, etc., it is easy to cause the deflection of the ventilation pipe.

Contents of the invention

The invention overcomes the deficiencies of the prior art, and the technical problem to be solved is to provide a tower ventilation pipe fastening device with simple structure and convenient installation.

In order to solve the above technical problems, the technical solution adopted in the present invention is: the fastening device for the ventilation pipe of the power line pole tower, including a pair of rivets and a tightening hoop, the rivets are U-shaped elbows, and the U-shaped elbows The two legs of the head are long and short, and the short leg is a riveted leg, and the length of the riveted leg is greater than the width of the angle steel used for the tower; the tail end of the long leg is provided with a lower fixing hole; The spacing is adapted to the thickness of the angle steel; the tightening hoop is a U-shaped hoop, and upper fixing holes are arranged at the tail ends of the two legs of the U-shaped hoop;

And in the state of use, the long leg is inserted into the riveting hole opened on the vertical surface of the angle steel, the two legs of the U-shaped hoop are against the outside of the vertical surface of the angle steel, the upper fixing hole is aligned with the lower fixing hole and connected by bolts and nuts, And the maximum distance from the outside of the vertical surface of the angle steel to the inside of the U-shaped hoop is equal to the outer diameter of the ventilation pipe.

When using, first of all, in the corresponding opening of the angle steel on the pole tower, insert the long legs of the two riveting components through the opening, and then insert the U-shaped hoop into the groove formed by the long and short legs of the U-shaped elbow and the side of the angle steel ( Preferably, a protrusion can also be provided on the upper end surface in front of the long leg, and a pit can be set on the corresponding lower end surface of the U-shaped hoop position), so that the U-shaped hoop can be kept from falling under the action of its own gravity and the action of the caliper of the groove. Reduce the necessity of artificial support and simplify the difficulty of bolt connection.

Further, in order to prevent the installation difficulty caused by the incomplete match between the U-shaped hoop and the ventilation pipe or the problem that the ventilation pipe hoop is not tight or loose, the long legs are set at the part of the lower fixing hole and the two legs of the U-shaped hoop Set the upper fixing hole and flatten it to set up a platform for the fixing hole. Both the lower fixing hole and the upper fixing hole are set on the platform and are both long holes. There are ring gaskets and wedges between the two platforms, and the bolts pass through the ring gaskets. After connecting the upper and lower fixing holes, wedging wedges at the two corners of the upper and lower platform depressions and dislocations can ensure the firmness of the installation.

Compared with the prior art, the present invention has the following beneficial effects.

The invention has simple structure and is convenient for installation. After the ventilation pipe is fixed up and down, one worker can complete the installation of the rest of the clamps. And it can adapt to the small discrepancy between the size of the hoop and the size of the ventilation pipe to ensure the firmness of the installation.
