Detailed ways

The technical solution of the present utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

Embodiment 1: A universal anti-fall device for communication towers as shown in Figures 1, 2, 3, 5 and 6, including a clamp 1, and the clamp 1 includes a first limiting piece 2 and a second limiting piece. piece 3, the two ends of the first limiting piece 2 and the two ends of the second limiting piece 3 are connected through studs or studs, and the first limiting piece 2 can be adjusted through threaded parts 5 such as bolts or studs. and the second limiting piece 3, so as to clamp the steel between the first limiting piece 2 and the second limiting piece 3. A V-shaped groove 4 is provided in the middle of the first limiting piece 2. Since The current common communication tower 21 structural main materials adopt angle steel structures, so the V-shaped groove 4 can be adapted to most angle steel materials, and the V-shaped groove 4 can increase the contact area with the angle steel, thereby increasing the angle steel The friction between the clamp 1 and the V-shaped groove 4 improves the clamping effect of the clamp 1 . A rope connector 6 is fixed on the back of the V-shaped groove 4 of the first limiting piece 2. The rope connector 6 is provided with at least one connection hole 7. In this embodiment, two connection holes 7 are provided, one of which is used to connect the rope 8. , the other can be used to install other structures.

The utility model also includes a rope 8 and a telescopic screw 9. One end of the telescopic screw 9 is provided with threads and is threaded in the connection hole 7 of the rope connector 6. The other end is provided with a collar 10 for passing through the rope 8. The rope 8 is hung on the telescopic screw 9; as shown in Figure 1, Figure 2 and Figure 3, the number of the telescopic screw 9 is two, which are respectively set on both ends of the rope 8, and finally the rope 8 is hung through the clamp 1 Located on the main material of the communication tower 21, after the rope 8 is hung on the collar 10 on the telescopic screw 9, the telescopic screw 9 located at the top of the communication tower 21 needs to be tightened upward, and the telescopic screw 9 located at the bottom of the communication tower 21 needs to be tightened downward. Tighten, so that the rope 8 can have a certain tightening force, prevent the rope 8 from shaking in the air, and improve the safety of certain operations; and because the tightening directions of the upper and lower telescopic screws 9 are opposite, the rope 8 itself also has tightening force and tightening force. function, making the strength of the rope 8 higher, further improving the safety of the operation. Since the two telescopic screws 9 are tightened to the top and bottom of the communication tower 21 respectively to straighten the rope 8, the rope 8 plays a role in pulling the two telescopic screws 9 toward the middle. Under the pulling force of the rope 8, the communication tower 21 The rope connector 6 of the clamp 1 at the top has a downward movement tendency, and the rope connector 6 of the bottom clamp 1 has an upward movement tendency. As shown in Figure 5, both rope connectors 6 will move against the steel of the communication tower 21. A torque is generated, and due to the action of the second limiting piece 3, the clamp 1 cannot rotate, which is converted into the extrusion force of the first limiting piece 2 and the second limiting piece 3 on the steel, further increasing the clamp 1 With the clamping force between the clamp 1 and the steel, the fixation between the clamp 1 and the steel is more reliable, thus producing a self-locking effect.

As shown in Figure 6, when the main steel material of the communication tower 21 is a circular steel material 20 structure, the clamp 1 can still fix the steel material, and a certain arc is provided at the connection between the V-shaped groove 4 and the first limiting piece 2 The structure can effectively avoid point contact between this part and the pipe and reduce the contact stress between the two. This part adopts the form of surface contact, which can effectively reduce the wear and damage there.

When the staff starts working on the communication tower 21, the staff can put the safety rope buckle on the rope 8, which plays a protective role for the staff and allows the staff to move more freely on the communication tower. , and the rope 8 can be used as another supporting component in addition to the communication tower 21, so that the operators can have one more focus point.

Embodiment 2: A universal anti-fall device for communication towers as shown in Figures 1, 4 and 7 to 9. The difference from Embodiment 1 is that there is at least one anti-fall device in the middle section of the communication tower 21. A clamp 1. A rope guide 12 is additionally installed on the rope connector 6 of the clamp 1. The rope guide 12 includes a connecting plate 13 and a rope limiting block 15. The connecting plate 13 is provided with a connection hole 7 corresponding to the rope connector 6. Through holes, the rope limiting block 15 is provided with a slot 14, and the slot 14 can accommodate the diameter of the rope 8. There are two connection holes 7 on the rope connector 6 on the clamp 1. One is used to connect the rope connector 6 to the connecting plate 13 of the rope guide 12, and the other is used to install on the rope connector 6 for limiting. The connecting piece 16 of the hook 17 slides. One end of the connecting piece 16 is fixed on the rope connector 6, and the other end is a cylindrical guide hole, which can make the limit hook 17 slide in the guide hole. The hook end of the limit hook 17 is in contact with the rope. The slot 14 end of the limit block 15 cooperates to block the rope 8 so that the rope 8 cannot escape from the slot 14. An elastic member 18 is provided between the other end of the limit hook 17 and the connecting piece 16. The elastic member 18 is a pressing force. Spring, under the action of the elastic member 18, the space between the limit hook 17 and the slot 14 is closed. When it is necessary to separate the limit hook 17 from the slot 14, it is only necessary to apply a force along the direction of the elastic member 18 to the limit hook 17. The elastic member 18 can be compressed by the tensile force, so that the limiting hook 17 is separated from the slot 14 .

There is a gap 23 in the middle of the limit hook 17, and corresponding to the position of the gap 23, the rope limit block 15 is provided with a notch 24 that is symmetrical with respect to the horizontal direction of the limit hook 17. There is a gap 23 between the gap 23 and the notch 24. The buckle 22 is connected, and a limiting block is engaged between the buckle 22 and the notch 24 to prevent the buckle 22 from being separated from the notch 24 . When the buckle 22 is inserted into the slot 24, the limit hook 17 can be fixed axially to prevent the rope 8 from being pulled out of the slot 14 due to excessive force perpendicular to the axial direction. When it is necessary to pull the limit hook 17, it is only necessary to pull out the buckle 22.

In this embodiment, an additional clamp 1 and a rope guide 12 are added to the middle section of the tower, mainly to prevent the rope 8 from being too long and causing violent shaking, and to slow down the shaking. The difference from Embodiment 1 is that when the staff is working, , move to the clamp 1 position in the middle of the tower body. You need to pass the safety rope buckle through clamp 1. At this time, you only need to pull out part of the buckle 22, and then pull the limit hook 17 to remove the rope 8 from the slot 24. Take it out, then pass the buckle of the safety rope around the clamp 1 from the rope 8, and finally put the rope 8 back into the slot 14, and then tighten the buckle 22.
