Description

Technical Field

[0001] The utility model relates to a lossless quick installation structure, in particular to a lossless quick installation structure. Background Art

[0002] Transmission towers, poles and other power facilities are built with angle irons specified in GB / T706-2016 Hot-rolled Steel. After the power facilities are built, new equipment needs to be installed on the angle irons for maintenance or replacement of equipment (such as adding warning lights or 5G equipment to signal towers). There are several ways to install new equipment on angle irons:

[0003] 1. U-shaped groove installation method, such as Figure 1 As shown, a U-shaped groove 32 is provided on one end of the equipment fixing bracket 31 that contacts the angle iron 20. After the fixing bracket 31 is locked to the angle iron 20 by means of screws 33, the other end of the fixing bracket 31 is connected to the equipment. This fixing method has the following defects: the torque generated when tightening the screws 33 will drive the fixing bracket 31 to rotate, and the fixing position is prone to deviation; tightening the screws 33 will cause the position of the U-shaped groove 32 to deform, and the structure is unstable; the notch side of the U-shaped groove 32 lacks obstruction, and is only fixed by friction provided by the screws 33, which has the risk of falling off, so this installation method is only suitable for light-weight equipment.

[0004] 2. Punching installation method, such as Figure 2 As shown, a hole is opened on the angle iron 20, and a screw 33 passes through the fixing bracket 31 and the angle iron 20, thereby fixing the device on the angle iron 20. This installation method requires opening a new installation hole on the angle iron 20, which will destroy the pressure-bearing strength of the angle iron 20 and pose a risk of affecting the overall strength of the iron tower; on the other hand, the operator needs to carry the hole-opening equipment to work at high altitude, which makes the installation difficult.

[0005] Therefore, how to provide an installation structure that is easy to install and will not damage the angle iron is a problem that needs to be solved. Utility Model Content

[0037] See also Figure 3 and Figure 4 The utility model provides a non-destructive quick installation structure 10, which includes: an angle iron bracket 100 and a fastening clamp 200. When it is necessary to install equipment on power facilities such as transmission towers, the non-destructive quick installation structure 10 is fixed to the angle iron 20 on it, and the equipment to be installed is connected to the angle iron bracket 100. For example, the non-destructive quick installation structure 10 is used to fix the bird repellent 30 on the transmission tower (such as Figure 7 shown).

[0038] See also Figure 3 and Figure 5 The angle iron bracket 100 includes an L-shaped sheet metal 110 and a fixing frame 120. The L-shaped sheet metal 110 is provided with two perpendicular contact portions 111. When the device is fixed, the contact portions 111 are in contact with the outer wall of the angle iron 20, and each contact portion 111 is provided with a distance adjustment hole 112. The L-shaped sheet metal 110 and the fixing frame 120 are welded together. Preferably, the fixing frame 120 is welded to one of the contact portions 111.

[0039] See also Figure 3 and Figure 4 A fastening clip 200 is provided on each contact portion 111, that is, a fastening clip 200 is provided at each end of the L-shaped sheet metal 110. When fixed, the L-shaped sheet metal 110 fits the outer wall of the angle iron 20, and the fastening clip 200 is used to clamp the L-shaped sheet metal 110 and the angle iron 20 together.

[0040] See also Figure 4 and Figure 6The fastening clamp 200 includes a screw 210, a base pad 220 and a pressure block 230 rotatably connected to the base pad 220. A relief portion 231 is provided on one side of the pressure block 230 connected to the base pad 220. The contact portion 111 is penetrated by the relief portion 231. Pushing the fastening clamp 200 can make it slide along the contact portion 111, thereby adjusting the position of the fastening clamp 200 on the contact portion 111, thereby adapting to angle irons 20 of different sizes.

[0041] See also Figure 3 and Figure 6 The screw 210 passes through the pressure block 230 and the distance adjustment hole 112 and is threadedly connected with the bottom washer 220. On the one hand, the screw 210 passes through the distance adjustment hole 112, so that the fastening clip 200 is limited on the contact portion 111 and will not fall off; on the other hand, the nut part of the screw 210 contacts the pressure block 230, and the other end is threadedly connected with the bottom washer 220. When the screw 210 is rotated, the nut position on the screw 210 moves toward the bottom washer 220, so that the pressure block 230 and the bottom washer 220 are close to each other, and then the contact portion 111 and the angle iron 20 are pressed to fix the contact portion 111.

[0042] The specific process of fixing new equipment on a transmission tower using the above-mentioned non-destructive quick installation structure 10 is as follows:

[0043] First, determine the installation location;

[0044] The L-shaped sheet metal 110 is placed on the angle iron 20 at the installation position, and the L-shaped sheet metal 110 is pushed so that the two contact parts 111 on it are in contact with the outer wall of the angle iron 20; preferably, a magnet 122 is provided at a position connected to the contact part 111 on the fixing frame 120. When the L-shaped sheet metal 110 is placed on the angle iron 20 at the installation position, the magnet 122 can absorb the angle iron 20 for temporary fixation, freeing the hands of the staff and further reducing the difficulty of installation.

[0045] Next, the fastening clip 200 is pushed along the contact portion 111 to bring the fastening clip 200 close to the angle iron 20, and then the screw 210 is screwed to bring the pressing block 230 and the bottom pad 220 close to each other, so that the contact portion 111 is pressed against the angle iron 20. Preferably, the bottom pad 220 is provided with a first clamping jaw 221, and the pressing block 230 is provided with a second clamping jaw 232. When the pressing block 230 and the bottom pad 220 are close to each other, the second clamping jaw 232 is pressed against the contact portion 111, and the first clamping jaw 221 is pressed against the angle iron 20. Figure 4 shown.

[0046] Finally, the device is connected to the fixing frame 120 by screws.

[0047] It can be seen from the above assembly process that the assembly process does not require drilling holes on the angle iron 20, and the structural strength of the angle iron 20 will not be damaged.
