The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a high-altitude power construction protection device of the utility model comprises a U-shaped plate 1, the bottom of the U-shaped plate 1 protrudes to form a thickened portion, an installation groove is provided on the inner side surface of the U-shaped plate 1 opposite to the thickened portion, a positioning wire clamp 2 is installed in the installation groove, both ends of the U-shaped plate 1 are installed with a support frame 4 sleeved on the cable, the top surface of the support frame 4 is provided with a mounting opening, the mounting opening is provided with a roller 5 installed in the mounting opening through a pin shaft, and the inside of the support frame 4 is provided with an extrusion rod 6 for locking the roller 5 inward.

[0021] In this embodiment, a plurality of positioning holes 7 are provided on the inner side surface of the support frame 4, and an adjustment plate 8 is installed at the opposite side of the extrusion rod 6 facing the positioning hole 7, and the adjustment plate 8 is arranged through the positioning hole 7. A fixing block 9 is installed on the inner side surface of the support frame 4 above the positioning hole 7, and screw holes are provided on the fixing block 9. Bearings are embedded on the top surface of the adjustment plate 8, and screws are threadedly connected in the screw holes. One end of the screw is installed in the inner ring of the bearing, and the other end is installed with a hand wheel 10.

[0022] In this embodiment, the edges of the top surface of the squeezing rod 6 are chamfered to form an arc-shaped structure, and the upper half of the squeezing rod 6 is inserted into the interior of the roller 5 .

[0023] In this embodiment, the U-shaped plate 1 is made of insulating rubber material, and a mesh structure of silk threads is arranged inside the U-shaped plate 1. The silk threads increase the strength of the U-shaped plate, avoid breakage, increase safety, and can be better rolled up through the rubber.

[0024] In this embodiment, both sides of the opening at the upper end of the installation groove are recessed to form a positioning groove, and the open end surface of the positioning wire clamp 2 is bent outward to form a positioning portion 3. The positioning portion 3 is installed in the positioning groove, and the top surface of the positioning portion 3 is flush with the inner surface of the U-shaped plate 1, thereby increasing the contact area between the positioning wire frame and the U-shaped plate, and can better fix the positioning wire clamp.

[0025] In this embodiment, the positioning wire clamp 2, the support frame 4, the roller 5 and the extrusion rod 6 are all made of engineering plastic materials, so that the above components have high mechanical strength, good heat resistance and good electrical insulation, so that they can be insulated while having strength, thereby increasing safety.

[0026] When not in use, the U-shaped plate can be bent or folded directly so that the U-shaped plate can be rolled up, which greatly reduces the volume and is convenient for carrying;

[0027] When in use, the U-shaped plate can be put on the cables distributed in the triangular structure from top to bottom, wherein the lower cable can be inserted into the positioning wire clamp, and the rollers on both sides can be put on the upper cable. After putting on, the screw rod can be rotated by the hand wheel to move the screw rod upward along the screw hole. The movement of the screw rod drives the adjusting plate, the adjusting plate and the extruding rod, so that the extruding rod can enter the outside of the roller and rub against the cable inside the roller. The rotation speed of the roller is changed by changing the degree of compression with the cable. When movement is required, the extruding rod can be slightly away from the cable to reduce the friction of the roller, so that the device can move quickly along the cable. Conversely, when the extruding rod is moved upward, the roller and the cable can be compressed and set, so that the device can be positioned at any person. The construction personnel can directly act on the inside of the U-shaped plate to rest, providing a rest and stepping platform for the construction personnel.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
