In order to better understand the utility model, the embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1 to FIG. 3 , the soft attachment 1 or 1a for connecting the pole and the iron tower provided by the preferred embodiment of the present invention is used to stabilize the pole 3 during the construction of the iron tower 5 of the pole 3 group. Wherein, the holding pole 3 is placed on the ground at the center of the iron tower 5 . A plurality of pole attachment frames 31 are fixed at intervals on the pole 3, and each pole attachment frame 31 is provided with a plurality of lugs 311, and each lug 311 is provided with a plurality of mounting holes for installing the soft attachment 1 (not labeled ). Preferably, in this embodiment, each pole attachment frame 31 has a rectangular shape, and each pole attachment frame 31 includes four lugs 311, and these four lugs 311 are respectively located on four sides of the rectangular pole attachment frame 31. on a corner.

Please refer to Figure 2. When the load is large, 12 soft attachments 1 of the utility model are used. These soft attachments 1 are evenly distributed between each pole attachment frame 31 and the iron tower 3, so that the soft attachment 1 is subjected to pressure in all directions in the plane. The force is balanced, even when the head of the pole 3 rotates 360 degrees, these soft attachments 1 can effectively stabilize the pole 1 . Specifically, three soft attachments 1 are respectively fixed on the four main materials of the iron tower 5 surrounding the pole 3, and these three soft attachments 1 are respectively connected to the lugs 311 and the On the two outer lugs 311 connected to the facing lug 311 .

Please refer to Fig. 3, adopt soft attachment 1 of 8 basic utility models when load is bigger. Based on the same reason as using 12 soft attachments 1 , these 8 soft attachments 1 are equally distributed between each pole attachment frame 31 and the iron tower 3 . Specifically, two soft attachments 1 are respectively fixed on the four main materials of the iron tower 5 surrounding the pole 3, and these two soft attachments 1 are respectively connected to the two main materials of the iron tower 5 facing each other. The lug 311 on the diagonal of the side.

Please refer to FIG. 4 , the soft attachment 1 for connecting the pole and the iron tower in the first embodiment of the present invention includes a cable 11 , several shackles 12 and a double-ended wire tensioner 15 . Wherein, the shackle 12 is a commercially available standard part.

Please refer to FIG. 5 , the double-headed wire tensioner 15 includes a main barrel 151 and a first adjusting rod 153 and a second adjusting rod 155 installed in both ends of the main body barrel 151 . The inner wall of the main cylinder 151 is provided with internal threads. One end of the first adjusting rod 153 and the second adjusting rod 155 away from the main cylinder 151 is provided with a closed pull ring 16 . Both the first adjusting rod 153 and the second adjusting rod 155 are provided with external threads engaged with the internal threads of the main cylinder 151 , and the external threads of the first adjusting rod 153 and the second adjusting rod 155 have opposite directions of rotation. For this purpose, only the main body cylinder 151 needs to be screwed, and under the action of the lead screw principle, the first adjusting rod 153 and the second adjusting rod 155 are separated from each other or approached to each other, thereby adjusting the total length of the double-headed wire tensioner 15, which can be operated at high altitude fast and convenient. Because the first adjusting rod 153 and the second adjusting rod 155 expand and contract at the same time, the adjustment stroke of the double-ended wire tensioner 15 is relatively large. Preferably, for the convenience of operation, a handle 17 is fixedly provided on the outer wall of the main cylinder 151 . Preferably, the double-ended wire tensioner 15 is a 10-ton double-ended wire tensioner.

The stay cable 11 is a commercially available standard crimped steel strand, and two opposite ends of the stay cable 11 are respectively crimped with crimped steel anchors 13 . The crimping steel anchor 13 at the first end of the dragline 11 is fixed with the construction hole (unlabeled) on the main material of the corresponding iron tower 5 through the shackle 12; the crimping steel anchor 13 at the second end of the dragline 11 is Through the fixing of the shackle 12 and the closed pull ring 16 of the first adjusting rod 153 of the double-headed wire tensioner 15, when the closed pull ring 16 and the shackle 12 are connected in series, the detachment is effectively prevented, and the reliability of the connection is increased. The closed pull ring 16 of the second adjusting rod 155 of the double-ended wire tensioner 15 is connected in the mounting hole of the lug 311 of the holding rod 3 through the shackle 12 .

And the minimum loads of the above-mentioned stay cables 11 , several shackles 12 and double-ended wire tensioners 15 are not less than the allowable tension of the entire soft attachment 1 .

Please refer to Fig. 6, the structure of the soft attachment 1a for connecting the pole and the iron tower in the second embodiment of the present invention is basically the same as that of the soft attachment 1 for connecting the pole and the iron tower provided in the first embodiment, the only difference is that this utility model The stay cable 11a of the soft attachment 1a connecting the pole and the iron tower in the new second embodiment is a commercially available single-ended wire rope sleeve. The stay cable 11a is a round strand steel wire rope with a diameter of 20mm. The first end of the pull cable 11a is configured to be inserted into the rope lug 111a. The insertion rope lug 111a includes an insertion section 113a with a length not less than 300mm and a first collar 115a, and the first collar 115a is connected to the insertion section 113a. The collar 115a is fixed to the corresponding construction hole (not labeled) on the main material of the iron tower 5 through the shackle 12 . The second end of the cable 11a is bent to form a bent section 13, and the bent section 13 and the cable 11a form a second collar 117a. The second collar 117a is fixed to the closed pull ring 16 of the first adjusting rod 153 of the double-ended wire tensioner 15 through the shackle 12 . The bending section 13 is clamped on the cable 11a by a rope clip 7, and by adjusting the position of the cable clip 7, the bending section 13 can be released, thereby adjusting the effective length of the entire cable 11a, which greatly increases the applicable range of the length , improving utilization. The minimum loads of the above-mentioned stay cables 11a, several shackles 12 and double-ended wire tensioners 15 are not less than the allowable tension of the entire soft attachment 1a. When the tower shape of the iron tower 3 is many, the attachment positions are changeable, and the length specifications of the soft attachment 1a or 1 are many, the use of the single-ended wire rope sheath 11a can reduce the number of processing configurations and save costs.

From the above description, it can be seen that the soft attachment 1 or 1a connecting the pole and the iron tower of the present utility model is formed by connecting cables 11 or 11a, some shackles 12 and double-headed wire tensioners 15, etc. The gourd and the hard-attached rigid rod are much lighter, and one person can easily handle it when installing or dismantling at high altitude, which reduces the difficulty of the operation and improves the efficiency; the materials and shackles 12 that make up the cable 11 or 1a are easy to purchase in the market. The price is reasonable and the cost is low; and the soft attachment 1 or 1a includes a double-ended wire tensioner 15 with a large adjustment stroke, which can adjust the length of the entire soft attachment 1 or 1a in a wide range.
