[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses a communication manhole adaptive optical cable laying device. (Refer to...)

The positions of the first support frame 1 and the second support frame 2 are fixed by using the outer fixing buckle 3 and the inner fixing buckle 6 respectively. At the same time, the support frame connecting rod 14 plays a supporting role. According to the position of the pipe 23, the positions of the first sliding wheel bracket 7 and the second sliding wheel bracket 10 are adjusted so that the first sliding wheel bracket 7 and the second sliding wheel bracket 10 are deflected at a certain angle.

[0034] Reference Figure 2 and Figure 5 as well as Figure 6 An adjustment mechanism 24 is mounted on both the first lower pulley bracket 7 and the second lower pulley bracket 10. The adjustment mechanism 24 includes two traction rods 2400, each fixedly mounted on the side of the first lower pulley bracket 7 and the second lower pulley bracket 10. A limit block 2401 is fixedly mounted at one end of each traction rod 2400. A traction block 2402 is movably mounted on each traction rod 2400. An extension block 2403 is fixedly mounted on each traction block 2402. The extension block 2403 is located above the first lower pulley bracket 7 and the second lower pulley bracket 10.

A connecting block 2406 is fixedly mounted at the bottom of the first lower pulley bracket 7 and the second lower pulley bracket 10. Vertical rods 2407 are symmetrically fixedly mounted on the bottom of the connecting block 2406. Limiting plates 2408 are fixedly mounted on the bottom of the two vertical rods 2407. Adjusting blocks 2409 are movably mounted on the two vertical rods 2407. Fixing plates 2410 are fixedly mounted on both symmetrical sides of the adjusting blocks 2409. Adjusting rods 2411 are movably mounted on the fixing plates 2410. The other end of the adjusting rods 2411 is movably mounted to the mounting plate 2405. A rotating cavity 2412 is provided inside the adjusting block 2409. Adjusting bolts 2413 are threaded on the limiting plates 2408. A rotating rod 2414 is fixedly mounted on one end of the adjusting bolts 2413. The rotating rod 2414 movably passes through the rotating cavity 2412, and a rotating disk 2415 that rotates in the rotating cavity 2412 is fixedly mounted on one end of the rotating rod 2414.

[0035] In this utility model, according to the model of the optical cable body 21, the adjusting bolt 2413 rotates and moves on the limiting plate 2408, causing the adjusting bolt 2413 to drive the rotating disk 2415 on the rotating rod 2414 to rotate on the rotating cavity 2412, allowing the adjusting block 2409 to move on the two vertical rods 2407. Under the pulling action of the adjusting rod 2411 on the traction block 2402, the traction block 2402 moves on the two traction rods 2400. The traction block 2402 drives the L-shaped support block 2404 on the extension block 2403 to move. The distance between the two L-shaped support blocks 2404 is adjusted so that the two L-shaped support blocks 2404 can be matched according to the model of the optical cable body 21, thereby improving the performance.

[0036] Working principle: Based on the size of the manhole 22, suitable support frame fixing holes 13 are found on the first support frame 1 and the second support frame 2. The positions of the first support frame 1 and the second support frame 2 are fixed by the outer fixing buckle 3 and the inner fixing buckle 6, respectively. Simultaneously, the support frame connecting rod 14 provides support. Based on the position of the pipe 23, the positions of the first sliding wheel bracket 7 and the second sliding wheel bracket 10 are adjusted, causing them to deflect at a certain angle. Then, the second sliding wheel bracket buckle 12 is threaded onto the first support frame 1 and the first sliding wheel bracket 7, and the first sliding wheel bracket buckle 11 is threaded onto the second support frame 2 and the second sliding wheel bracket 10, fixing the angle of the first sliding wheel bracket 7 and the second sliding wheel bracket 10. The sliding wheel body 9 is close to the pipe 23. Based on the model of the optical cable body 21, the adjusting bolt 2413 is adjusted at the limit plate. The adjustment bolt 2413 rotates and moves on the rotating rod 2414, causing the rotating disk 2415 on the rotating rod 2414 to rotate on the rotating cavity 2412. This causes the adjustment block 2409 to move on the two vertical rods 2407. Under the pulling action of the adjustment rod 2411 on the traction block 2402, the traction block 2402 moves on the two traction rods 2400. The traction block 2402 drives the L-shaped support block 2404 on the extension block 2403 to move. The distance between the two L-shaped support blocks 2404 is adjusted so that the two L-shaped support blocks 2404 can be matched according to the model of the optical cable body 21, improving the usage effect. The optical cable body 21 moves between the first guide wheel 4 and the second guide wheel 5. Through the traction of the sliding pulley body 9, the optical cable body 21 passes through the pipe 23, avoiding the need for downhole operation, improving operational safety, and at the same time improving the construction progress and reducing construction costs.
