Detailed Description
As shown in fig. 1, the split composite insulating cross arm comprises a connecting frame 1 sleeved on a telegraph pole 8 and a fastener 3, and is different from a conventional double-connecting-frame 1 combined connection mode, and the novel structure adopted by the device is easier to fix;
and the fixing mode of the connecting frame 1 and the fastener 3 is as follows:
in order to adapt to the utility pole 8, the connecting frame 1 comprises an arc-shaped frame 11, one side of the arc-shaped frame 11, which is close to the utility pole 8, is arc-shaped, when in use, one side of the arc-shaped frame is aligned with the utility pole 8, the two ends of the connecting frame 1 are fixedly provided with the fastening plates 2, and the fastening plates 2 are arranged perpendicular to the connecting frame 1, preferably, the fastening plates 2 can be fixed with the connecting frame 1 by welding, so that the connecting frame is more stable;
as shown in fig. 4 and 5, the fastening member 3 includes a fastening belt 31 and fastening bolts 32 fixed at both ends of the fastening belt 31, the fastening belt 31 is a flat belt-shaped structure, and a plurality of steel wires are arranged inside, and then the fastening belt 31 is made into a structure by weaving, or the fastening belt 31 can be obtained by fixedly arranging the fastening bolts 32 at both ends by using an existing sling structure with a proper length;
then, the fastening plate 2 is provided with fastening holes through which fastening bolts 32 can pass, the fastening bolts 32 can be fixed by fixing nuts 4 after passing through the fastening holes, and the fixing nuts 4 cannot pass through the fastening holes, so that when the fastening member 3 is used, the fastening bolts 32 at any section of the fastening member 3 can pass through the fastening holes and be fixed by the fixing bolts 4, and then, the fastening member 3 only needs to pass around the utility pole 8, and after the fastening bolts 32 at the two other ends pass through the fastening holes at the opposite sides, the positions of the fastening bolts 32 relative to the fastening plate 2 can be adjusted by adjusting the fixing nuts 4, and finally, the fastening belt 31 can be tightened to fix the connecting frame 1 on the utility pole 8, or the fastening belt 31 can be loosened to enable the connecting frame 1 to move up and down or be detached relative to the utility pole 8;
since the fastening plate 2 needs to bear the tensile force of the fastening member 3, a reinforcing connecting plate 13 is preferably disposed between the fastening plate 2 and the connecting frame 1. Can strengthen being connected of mounting plate 2 and link 1, just reinforcing connecting plate 13 can directly adopt welded mode to be connected with mounting plate 2 and link 1. As shown in fig. 2, the reinforcing connecting plate 13 is disposed on the side of the fastening plate 2 close to the utility pole 8, and ensures that the fastening plate 2 does not bend or break when it receives the tensile force of the fastening member 3.
However, in the above-described structure, if the fastening hole 2 is provided on the side of the connecting bracket 1 close to the utility pole 8, the fastening member 3 has a small contact area with the utility pole 8 when applied, and therefore, there is a phenomenon that the fixing effect is poor, and in order to improve the fastening effect of the above-described structure, as shown in fig. 2 and 3, it is preferable to further:
the fastening plate 2 is arranged on one side of the connecting frame 1, which is away from the telegraph pole 8, and meanwhile, in order to ensure that the fastening piece 3 can be used normally, two openings which can be penetrated by the fastening piece 3 need to be arranged on the connecting frame 1, and the two openings are respectively located on two sides of the telegraph pole 8. Through the arrangement of the structure, when the fastening piece 3 is used, any section of the fastening piece 3 can be fixed with the fastening plate 2, the fixing nut 4 is arranged on the fastening plate 2 away from the telegraph pole 8, then the other end of the fastening piece 3 firstly penetrates through the hole and winds around the telegraph pole 8 and then penetrates through the other hole, and the fastening piece 1 is fixed on the other fastening plate 2 on one side away from the telegraph pole 8, the structure is shown in figures 2 and 3, the contact area between the fastening piece 3 and the telegraph pole 8 is effectively increased, so that the fixing effect is better, the operation process is not required to be completed at the top end of the telegraph pole 8, the fastening process is required to be completed at the top end of the telegraph pole 8 only by hitching the fastening piece on the telegraph pole 8 below.
On the basis of the structure, further, two openings are symmetrically arranged on the connecting frame 1, the stress is more uniform, and the openings are inclined holes. The opening interval of two inclined holes in one side that link 1 is close to wire pole 8 is less than the opening interval of two inclined holes in one side that link 1 deviates from wire pole 8, and when taut fastener 3, the resistance is littleer, and fastening effect is better, and above-mentioned inclined holes correspond the route trend of fastener 3, consequently can avoid the sharp-pointed part to contradict fastener 3 causes its braided wire or plastic casing damage to lead to rusty phenomenon.
Through the fixed mode that uses above-mentioned fastener 3, can be applicable to the fixed requirement of wire pole 8 of different diameters, and when above-mentioned structure is fixed, only need accomplish the fastening of a bolt on wire pole 8 and can accomplish fixed requirement, compare in the mode of current a plurality of bolt fastening, labour saving and time saving more compares in current structure, possess the progress that is showing.
As shown in fig. 2, the side of the connecting frame 1 close to the utility pole 8 is preferably provided with an auxiliary pole 14, and the auxiliary pole 14 is arranged opposite to the fastening bolt 32. Before the fixing nut 4 is not arranged in front of the fastening bolt 32, the fixing nut 4 can be sleeved on the auxiliary rod 14, so that the auxiliary rod 14 is convenient to take and place, the auxiliary rod 14 is also a bolt rod, the type of the auxiliary rod is the same as that of the fastening bolt 32, the disassembled fixing nut 4 can be screwed on the auxiliary rod 14 to prevent loss, and after the fixing nut 4 is fixed by the single fastening bolt 32, if the fixing nut 4 is prevented from slipping off, the fixing nut 4 can be sleeved on the fastening bolt 32, namely, the two fixing nuts 4 are sleeved, so that the occurrence of accidents can be effectively prevented.
After the structure is completed, the connecting frame 1 can be fixed relative to the utility pole 8, and further, a detachable composite cross arm 5 is arranged on one side of the connecting frame 1, which is far away from the utility pole 8, and a plurality of insulators are arranged on the composite cross arm 5. Thereafter, the application can be performed normally, and as shown in fig. 1, one or two of the composite cross arms 5 can be provided at the same time. Depending on the requirements.
As shown in fig. 1, a vertical fixing platform 12 is disposed on a side of the arc frame 11 away from the utility pole 8, the fixing platform 12 is used for connecting the composite cross arm 5, and a plurality of holes may be disposed on the fixing platform 12 for connecting the composite cross arm 5.
Meanwhile, because the fastening plate 2 is additionally arranged in the device, preferably, in order to improve the stability of the composite cross arm 5, one end, away from the connecting frame 1, of the fastening plate 2 is provided with a bent part 21, and the bent part 21 and the fixed platform 12 are on the same vertical plane.
Then, in addition to the above structure, the composite cross arm 5 is connected to the fixed platform 12 by the first connecting bolt 6, and connected to the bent portion 21 by the second connecting bolt 7. The starting point of the cantilever is arranged at the position of the second connecting bolt 7, so that the cantilever effect can be effectively reduced, and the stability of the composite cross arm 5 is further improved.
