Description

Angle steel tower ventilation pipe fastening device

technical field

The invention relates to a ventilation pipe fastening device, in particular to an angle steel 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 fastening device for the ventilation pipe of an angle steel tower with a simple structure and convenient installation.

In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: the fastening device for the ventilation pipe of the angle steel tower, including a pair of rivets and a hoop, and the rivets and the hoop are made of round steel bars of uniform diameter. become;

The rivet is a U-shaped elbow, the two legs of the U-shaped elbow 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 pole tower, and the riveted leg The tail section of the leg is a connecting screw with an anchor nut; the tail end of the long leg is provided with a tightening nut, and the tightening nut can rotate freely at the tail end of the long leg. Insert the tail end of the long leg into the nut and flatten the top end; the distance between the long leg and the short leg is suitable for the thickness of the angle steel;

The tightening hoop is a U-shaped hoop, and the tail ends of the two legs of the U-shaped hoop are provided with external threads that match the tightening nuts.

In particular, in order to prevent the free-rotating clamping structure between the tightening nut and the tail end of the long leg, a double-threaded connection can also be used, that is, a thread is provided at the tail end of the long leg, and a tightening nut is arranged on the thread. Align the external thread at the end of the foot of the U-shaped hoop with the two tightening nuts, and turn the nut so that it is screwed in from the thread at the end of the long leg, and then screwed into the end of the foot of the U-shaped hoop the external thread on the end until the vent tube is snapped securely. The length of the tightening nut, the thread length of the tail end of the long leg and the length of the external thread of the leg tail end of the U-shaped hoop can be designed according to actual needs.

Further, the fastening device also includes an additional rubber gasket, which is used at the position where the ventilation pipe contacts the angle steel. The preset rubber gasket can reduce the wear on the ventilation pipe on the one hand, and also can Help the clamp to clamp the ventilation pipe more firmly.

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 relatively large mismatch between the size of the hoop and the size of the ventilation pipe to ensure the firmness of the installation.
