Description

A new cable tensioning structure for flying tower

【Technical field】

The invention relates to a novel cable tensioning structure of a flying tower.

【Background technique】

The flying tower generally includes a pylon, on which a skid is arranged, and the skid rotates and slides up and down and needs a power supply, generally a power supply is provided on the tower, and then the power supply is connected to the skid by a cable. In some cases, accompanying cables are installed on the tower, and the accompanying cables rotate and slide up and down with the slide frame. In this cable installation structure, the accompanying cables are directly exposed outside, and themselves bear wind resistance. Shaking and pulling may occur in the air, which will affect their service life. Some are to install the trolley line on the tower. Since the tower is 50 to 60 meters high, the length of each section is generally 6 meters due to the length specification of the trolley line. Many sections of the trolley line need to be spliced; The overall straightness of the contact line is prone to problems such as poor contact between the carbon brush and the trolley line, and poor waterproof effect; the transition between the trolley line and the trolley line is not smooth, the power and communication effects are poor, and the reliability is low.

【Content of invention】

The object of the present invention is to overcome the deficiencies of the prior art, and provide a cable tensioning structure of the flying tower with simple structure, good processing technology, good power and communication effects, and high reliability.

The purpose of the present invention is achieved like this:

A new type of cable tensioning structure for a flying tower. The flying tower includes a tower. The tower is provided with a sliding frame that can slide and rotate on the tower. Cables are connected between the frames, and the feature is that a pair of rails are provided on the tower, and the pair of rails is provided with a tensioning mechanism that can slide on and under the rails and can tighten the cables.

A new type of cable tensioning structure for flying towers as described above is characterized in that the tensioning mechanism includes a trolley that slides above and below the track, and the trolley is provided with a tensioning wheel, and the cable bypasses the tensioning wheel. tight wheel.

A novel cable tensioning structure for a flight tower as described above is characterized in that the tensioning wheel is provided with a wheel groove for the cable to bypass.

A new type of cable tensioning structure for flying towers as described above is characterized in that the pair of rails are provided with grooves with a C-shaped cross section, and the two sides of the tensioning wheel snap into the grooves, and the cables are stuck in the tensioning between the wheel and the track.

A new type of cable tensioning structure for the flying tower as described above is characterized in that the trolley is provided with rollers that cooperate with the track.

The present invention is owing to be provided with a pair of track on the track, and this pair of track is provided with the trolley that can slide up and down on track, and described trolley is provided with tension wheel, and described cable walks around tension wheel. The trolley always maintains a downward pulling force under the action of its own gravity. Since the cable is wound on the tension wheel of the trolley, the cable can be tightened all the time so that the cable is always in a tight state without shaking, Winding and other phenomena, simple structure, good processing and manufacturing technology, good power and communication effects, and high reliability.

【detailed description】

A new type of cable tensioning structure for a flying tower, the flying tower includes a tower 1, the tower 1 is provided with a sliding frame 2 that can slide and rotate on the tower, and the tower 1 is provided with a power supply for the sliding frame 3. A cable 4 is connected between the power supply 3 and the slide frame 2. A pair of rails 5 are provided on the tower. The pair of rails 5 are provided with a tensioning mechanism 7 that can slide on and below the rails and tighten the cable 4. The cable is always kept in a tight state by the tensioning mechanism 7, and phenomena such as shaking and entanglement do not occur.

The tensioning mechanism 7 of the present invention includes a trolley 71 that slides up and down the track, and the trolley 71 is provided with a tensioning wheel 72 , and the cable 4 bypasses the tensioning wheel 72 . The pulling cart 71 always maintains a downward pulling force under the action of its own gravity. Since the cable is wound on the tension wheel of the pulling cart, the cable can always be tightened so that the cable is always kept in a tight state without shaking , winding and so on.

The pulley 72 of the present invention is provided with a wheel groove 73 for the cable 4 to bypass, so that the cable can be stuck on the pulley and will not easily break away from the pulley, and no other structures need to be installed to fix the cable on the tensioning wheel.

The pair of rails 5 of the present invention are all provided with a groove 51 with a C-shaped cross section. The cable can be stored in the groove 51 of the track like this, can better protect the cable, and the pulling of the trolley will not easily break away from the track, and the cable will not break away easily.

The present invention is provided with the roller 711 that cooperates with track on the trolley 71, can be respectively provided with one pair or two pairs of roller 711 on both sides of trolley 71.
