[0002] With the popularization of power systems, electricity has become an indispensable part of people's daily lives. Moreover, 110 kV is the voltage of high voltage electricity, and high voltage lines are often installed overhead. High voltage overhead lines require manual climbing of pole tower structures for inspection and maintenance. Operators are at high risk of working at high altitudes, so necessary high-altitude protection measures must be taken.

[0003] A common height protection measure is that the operator wears a safety rope, climbs to the crossarm of the pole tower, and fixes the safety rope on the pole tower. However, when the operator needs to move for maintenance on the crossarm, the length of the safety rope is difficult to meet the operator's moving distance. The operator needs to frequently change the position of the safety rope hook to move, which is inconvenient to use and has low maintenance efficiency. At the same time, the connection between the safety rope and the crossarm cannot provide a stable and reliable support point. It often happens that the operator hooks the safety rope and the crossarm and connects them unstably, resulting in falling from a height, which is highly dangerous and has great safety hazards.

The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0030] like Figure 1-Figure 6 As shown, the present invention discloses a 110 kV steel pipe cross arm safety protection device and a method of using the same. The device comprises: a clip 31, a base 41, a fixing structure and a protection structure, wherein the left and right ends of the base 41 are engaged with the clip 31, and the clip 31 comprises: a first clip 33, a second clip 34 and a connecting plate 35, wherein a first clip 33 facing vertically downward is arranged in the middle of the connecting plate 35, and two second clips 34 facing vertically downward are arranged at both ends of one side, and the first clip 33 and the second clip 34 are arranged vertically downward. Both extend into the interior of the base 41, and a gap is left between the lower surface of the connecting plate 35 and the upper surface of the base 41. The bottom of the cross arm I-beam 21 is set in the gap, and one end of the lower surface of the connecting plate 35 is in contact with the bottom of the cross arm I-beam 21. A clip opening 32 is provided between the first clamping plate 33 and the second clamping plate 34, and a base opening 43 is provided on the base 41 corresponding to the position of the clip opening 32. The fixing structure passes through the clip opening 32 and the base opening 43 to fix the base 41 and the clip 31, and a protective structure is provided on one side of the base 41.

[0031] like Figure 5 As shown, two first card openings 44 are symmetrically provided on the inner side of the upper surface of the base 41, and four second card openings 45 are symmetrically provided at the four corners of the outer side of the base 41. The first card opening 44 is adaptively matched with the size and shape of the first card 33, and the second card opening 45 is adaptively matched with the size and shape of the second card 34.

[0032] like Figure 1 As shown, the first clamping plate 33 and the second clamping plate 34 on the clip 31 extend into the first clamping plate opening 44 and the second clamping plate opening 45 respectively, so that the clip 31 and the base 41 are clamped and fixed, and a base opening 43 is provided between the first clamping plate opening 44 and the second clamping plate opening 45 on the base 41 at a position corresponding to the clip opening 32, and at the same time, a gap is left between the lower surface of the connecting plate 35 on the clip 31 and the upper surface of the base 41, and the bottom of the cross arm I-beam 21 is set in the gap, and the connecting plate 35 and the base 41 clamp and fix the bottom of the cross arm I-beam 21.

[0033] like Figure 1As shown, the fixing structure includes: a T-shaped tightening rod 52, a tightening cap 53 and a fixing pad 54. The T-shaped tightening rod 52 is in a T-shaped structure. An external thread is provided at the upper end of the T-shaped tightening rod 52. Internal threads are provided in the base opening 43 and the clip opening 32. The upper end of the T-shaped tightening rod 52 is screwed to the base opening 43 and the clip opening 32 in turn through the internal and external threads.

A fixing pad 54 is provided between the tightening cap 53 and the upper surface of the clip 31.

[0034] In a specific embodiment, a gap is left between the bottom ends of the first clamp plate 33 and the second clamp plate 34 and the lower surface of the base 41, so the first clamp plate 33 and the second clamp plate 34 do not fully extend into the first clamp plate opening 44 and the second clamp plate opening 45, and one end of the connecting plate 35 clamps the bottom of the cross arm I-beam 21, and under the clamping force, the clip 31 can move on the cross arm I-beam 21 and does not detach, ensuring that the clip 31 can always clamp the cross arm I-beam 21. The operator adjusts the clamping force of the clip 31 on the cross arm I-beam 21 by rotating the tightening cap 53 on the fixing structure in the forward and reverse directions, thereby controlling the device to move and fix in the horizontal direction of the cross arm I-beam 21, which is more convenient to use and more convenient to adjust the position of the device according to the operator's maintenance needs.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, two second clamping plates 34 are symmetrically arranged front and back along the direction of the cross arm I-beam 21 , and the second clamping plates 34 and the first clamping plates 33 are distributed in an isosceles triangle in the horizontal direction, thereby improving the stability and reliability of the clip 31 .

[0036] like Figure 1 As shown, a buffer pad 42 is installed between the lower surface of the cross arm I-beam 21 and the upper surface of the base 41 to avoid a rigid connection, thereby improving the durability of the device and the cross arm I-beam 21.

[0037] like Figure 6 As shown, the protective structure includes: a support platform 63, a placement bag 65, a protective belt 66 and a protective hook 67. One side of the support platform 63 is fixedly connected to the base 41 and a hole is set on the other side. The protective belt 66 is set in the hole. The length of the protective belt 66 is fixed and can be pulled out from the hole. One end of the protective belt 66 is connected to the protective hook 67, and the protective hook 67 is connected to the protective buckle on the operator to prevent the operator from falling from a height, thereby improving safety. Placement bags 65 are set on the left and right sides of the support platform 63 to facilitate the operator to place and take out inspection and maintenance tools, thereby preventing the operator from dropping tools from the crossbeam and injuring people while working, thereby improving safety.

[0038] The working principle of the 110 kV steel pipe cross arm safety protection device of the present invention is as follows: the first clamping plate 33 and the second clamping plate 34 on the two clamping pieces 31 are extended into the first clamping plate opening 44 and the second clamping plate opening 45 on the base 41, and a gap is left between the bottom ends of the first clamping plate 33 and the second clamping plate 34 and the lower surface of the base 41, and the cross arm I-beam 21 is arranged in the gap between the connecting plate 35 on the clamping piece 31 and the base 41, and the connecting plate 35 and the base 41 are clamped together to clamp the bottom of the cross arm I-beam 21, and the T-shaped tightening rod 52 passes through the base opening 43 and the clamping piece opening 32 to make the base 41 is fixedly connected to the clip 31, the top end of the T-shaped tightening rod 52 passes through the outer wall of the clip 31, and the protruding part of the T-shaped tightening rod 52 is screwed to the tightening cap 53. The operator adjusts the clamping force of the clip 31 on the cross arm I-beam 21 by rotating the tightening cap 53 on the fixed structure in forward and reverse directions, and then controls the device to move or fix in the horizontal direction of the cross arm I-beam 21 as needed. The operator places the tool in the placement bag 65, and then the operator pulls out the protective belt 66, connects the protective hook 67 with the protective buckle on the body, and then uses the device to prevent the staff from falling from a height.

[0039] The present invention also discloses a method for using a 110 kV steel pipe cross arm safety protection device, comprising the following steps:

[0040] Step 1: The upper surface of the base 41 is pressed against the bottom of the cross arm I-beam 21, and the first clamping plate 33 and the second clamping plate 34 on the two clips 31 extend into the first clamping plate opening 44 and the second clamping plate opening 45 on the base 41, and one end of the connecting plate 35 is pressed against the upper surface of the bottom of the cross arm I-beam 21;

[0041] Step 2: Pass the T-shaped tightening rod 52 through the base opening 43 and the clip opening 32 to fix the base 41 and the clip 31, the top end of the T-shaped tightening rod 52 passes through the outer wall of the clip 31, and the protruding part of the T-shaped tightening rod 52 is screwed to the tightening cap 53;

[0042] Step 3: The operator rotates the tightening cap 53 in the forward direction to reduce the clamping force of the clip 31 on the cross arm I-beam 21, and controls the device to move in the horizontal direction of the cross arm I-beam 21 as needed. Rotating the tightening cap 53 in the reverse direction will increase the clamping force of the clip 31 on the cross arm I-beam 21 and thus fix the device on the cross arm I-beam 21;

[0043] Step 4: The operator pulls out the protective belt 66 and connects the protective hook 67 to the protective buckle on the body, thereby preventing the worker from falling from a height through this device.

[0044] The beneficial effect of the present invention lies in that, compared with the prior art, the present invention clamps and fixes the crossarm I-beam through the clamping piece and the base, and one end of the connecting plate clamps the bottom of the crossarm I-beam. Under the clamping force, the clamping piece can move on the crossarm I-beam and does not fall off, ensuring that the clamping piece can always clamp the crossarm I-beam, thereby improving reliability. Then, the clamping force is controlled by rotating the tightening cap on the fixing structure, thereby controlling the horizontal movement and fixation of the device on the crossarm I-beam, which is convenient for the operator to move the position of the device on the crossarm according to the inspection and maintenance position. It is more convenient to use, improves work efficiency, and enables the device to provide safety protection for the operator at any position to prevent falling.

[0045] Moreover, the connection between the protective hook and the protective buckle on the operator provides a stable and reliable support point for the operator, reducing the risk of the operator replacing the protective rope hook lock and making it more convenient to use. Placement bags are set on the left and right sides of the support table to facilitate the operator to place and take inspection and maintenance tools, avoiding tools falling from the crossarm and injuring people while the operator is working, thereby improving safety.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
