[0024] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0025] Refer to the attached Figure 2-5 , which shows a specific embodiment of the present invention; as shown in the figure, a transmission line anti-falling suspension wire clamp device disclosed by the present invention comprises: two hanging plates 1, a wire clamp hull 2, a hull hanging shaft 3 and two connecting bolts 4, the wire clamp hull 2 ​​is arranged between the two hanging plates 1, the hull hanging shaft 3 passes through the wire clamp hull 2 ​​and the two hanging plates 1, the hull hanging shaft 3 is rotatably connected with the hanging plates 1, pins 5 are inserted at both ends of the hull hanging shaft 3, the two hanging plates 1 are fixedly connected by connecting bolts 4, locking nuts 6 are provided on the connecting bolts 4, the connecting bolts 4 and the locking nuts 6 are respectively connected with bolt limiters 7 and nut limiters 8, the wire clamp hull 2 ​​is arranged between the upper and lower connecting bolts 4, and the connecting bolts 4 are also provided with pins 5.

[0026] The bolt stopper 7 includes a first sleeve 71, which is slidably connected to the hanging plate 1, and is connected to a first stop plate 72. The first stop plate 72 and the first sleeve 71 form a clamping groove 73 that matches the head of the connecting bolt 4. The first sleeve 71 slides upward, the connecting bolt 4 passes through the hanging plate 1, and the first sleeve 71 slides downward under the influence of its own gravity, and the clamping groove 73 clamps the head of the connecting bolt 4, limiting the withdrawal of the connecting bolt 4 from the hanging plate 1.

[0027] The first sleeve 71 is provided with a first bolt hole 74 extending therethrough, and the connecting bolt 4 passes through the first bolt hole 74. The first sleeve 71 moves up and down along the connecting bolt 4 through the first bolt hole 74. The first sleeve 71 slides downward under the influence of its own gravity. The setting of the first bolt hole 74 enables the slot 73 to better clamp the head of the connecting bolt 4.

[0028] The nut stopper 8 includes a second sleeve 81, which is slidably connected to the hanging plate 1, and is connected to a second stopper plate 82. The second stopper plate 82 and the second sleeve 81 form a stopper groove 83 adapted to the locking nut 6. The second sleeve 81 slides upward, the connecting bolt 4 passes through the hanging plate 1, and the second sleeve 81 slides downward under the influence of its own gravity, and the stopper groove 83 clamps the locking nut 6, limiting the locking nut 6 from withdrawing from the connecting bolt 4.

[0029] The second sleeve 81 and the second limiting plate 82 are provided with a second bolt hole 84 extending therethrough, and the connecting bolt 4 passes through the second bolt hole 84. The second sleeve 81 moves up and down along the connecting bolt 4 through the second bolt hole 84. The second sleeve 81 slides downward under the influence of its own gravity. The setting of the second bolt hole 84 enables the limiting groove 83 to better clamp the locking nut 6.

[0030] The outer sides of the two hanging plates 1 are respectively provided with a first slide groove and a second slide groove, the first limit plate 72 slides up and down along the slide groove, and the second limit plate 82 slides up and down along the second slide groove. The first slide groove is provided to prevent the bolt stopper 7 from falling off from the hanging plate 1, so that the bolt stopper 7 and the hanging plate 1 become a whole. The second slide groove is provided to prevent the nut stopper 8 from falling off from the other hanging plate 1, so that the bolt stopper 7 and the other hanging plate 1 become a whole.

[0031] The connecting bolt 4 located below the wire clamp hull 2 ​​is sleeved with a limit tube 9. This arrangement can prevent the locking nut 6 of the connecting bolt 4 at the lower end of the hanging plate 1 from having too large a tightening stroke when assembling the suspension wire clamp, resulting in the upper connecting bolt 4 being unable to be installed or being insufficiently tightened, and the pin 5 being unable to be installed.

[0032] Tightening sections 11 are provided at both upper and lower ends of the two hanging plates 1 , and the cross section of the tightening section 11 gradually decreases from the wire clamp hull 2 ​​toward the end of the hanging plate 1 .

[0033] This embodiment further includes a pressing plate 100 and a U-shaped bolt 200 . The U-shaped bolt 200 fixes the pressing plate 100 on the wire clamp hull 2 ​​. The pressing plate 100 is arranged at the upper end of the wire clamp hull 2 ​​.

[0034] The clamp hull 2 ​​and the pressure plate 100 are both made of cast iron.

[0035] The assembly process of the suspension wire clamp is as follows: first install the pressure plate 100 into the wire clamp hull 2, and then use the U-bolt 200 to tighten and fix the pressure plate 100. Then assemble the hanging plate 1, pass the connecting bolt 4 through the hanging plate 1, the first bolt hole 74 and the second bolt hole 84, tighten the locking nut 6, insert the pin 5, and complete the assembly. The bolt limiter 7 and the nut limiter 8 move downward under the action of their own gravity, so that the head of the connecting bolt 4 and the locking nut 6 are respectively inserted into the slot 73 and the limiting slot 83. When the pin 5 on the connecting bolt 4 is missing, the slot 73 and the limiting slot 83 will always prevent the connecting bolt 4 and the locking nut 6 from withdrawing.

[0036] In the present invention, the upper and lower ends of the hanging plate 1 are fixed by connecting bolts 4 to form a sealing structure. When the hull hanging shaft 3 in the middle of the hanging plate 1 is broken or the pin 5 is missing, the dropped wire clamp hull 2 ​​and the wire will be dragged by the connecting bolts 4 under the hanging plate 1, which plays a double protection role. By setting a bolt stopper 7 and a nut stopper 8 to prevent the connecting bolt 4 and the locking nut 6 from withdrawing respectively, the sealing structure formed by the hanging plate 1 and the connecting bolt 4 will not be destroyed, providing double protection for the wire clamp hull 2.

They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
