It is clear that the described embodiment 1 is a part of the embodiment of the present invention, not the whole embodiment. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

Example one

As shown in fig. 1-2, the embodiment provides a high altitude disconnecting link overhaul protection frame, which includes a fixed frame 12, a first support rod 2, a second support rod 3 and a safety rope prepared hole 5, where the fixed frame 12 is composed of two parallel transverse beam rods 1, an L-shaped bolt 11, a first fastening bolt 6 and a second fastening bolt 7, the L-shaped bolt 11 is vertically and movably disposed at one end of the two parallel transverse beam rods 1, the bottom of the first support rod 2 is vertically and fixedly disposed at the other end of the two parallel transverse beam rods 1, the safety rope prepared hole 5 is disposed at one end of the second support rod 3, and the other end of the second support rod 3 is vertically and movably connected to the top of the first support rod 2 through a rotary drum 9.

Preferably, set up dead lever 4 between first bracing piece 2 and the second bracing piece 3, 4 one ends of dead lever and 3 bottom fixed connection of second bracing piece, 4 other ends of dead lever are through pivot 10 and 2 swing joint of first bracing piece, through setting up dead lever 4, can make and form a stable triangle-shaped structure between first bracing piece 2 and the second bracing piece 3, and the safety rope can produce certain tension to the bracing piece when the maintainer makes a round trip to move on maintenance equipment, and dead lever 4 can make whole switch overhaul protection frame more stable.

Preferably, first bracing piece 2 and second bracing piece 3 are scalable cylinder pole, and the sleek no edges and corners in columniform bracing piece edge can reduce the friction when contacting with the safety rope thereby reduce the wearing and tearing to the safety rope to guarantee the security performance of safety rope, thereby set up scalable cylinder pole and can avoid overhauing the very big inconvenient carrying of protective frame is done with the switch because of can not adjusting the size, the structure of concertina type can be that whole switch overhauls the protective frame more portable, brings the facility for maintenance work.

Preferably, the perpendicular activity of first fastening bolt 6 sets up on the horizontal beam pole 1 on upper portion, the perpendicular activity of second fastening bolt 7 sets up in 2 lower parts of first bracing piece, when needs overhaul the knife-switch protection frame and fix on the channel-section steel of fixed point, makes fixed frame 12 fix at the fixed point through adjusting first fastening bolt 6 and second fastening bolt 7, first fastening bolt 6 and 7 bottoms of second fastening bolt all set up rubber gasket 8, and rubber gasket 8 can increase the frictional force between the contact surface of fastening bolt bottom and channel-section steel to it is more stable to make whole knife-switch overhaul protection frame structure.

Preferably, first bracing piece 2 and 3 materials of second bracing piece are light-duty FRP pipe, and light-duty FRP pipe has insulating, high strength, convenient to carry's characteristics, because need carry more instrument when electric power overhauls, the light material of easily carrying can alleviate the pressure of maintenance work.

When the safety device works, the L-shaped bolt 11 is firstly pulled out, the two parallel transverse beam rods 1 are respectively arranged at the upper part and the lower part of the disconnecting link fixing channel steel, then the L-shaped bolt 11 is inserted into the two parallel transverse beam rods 1, then the first fastening bolt 6 and the second fastening bolt 7 are respectively adjusted, so that the whole fixing frame 12 is stably arranged on the disconnecting link fixing channel steel, then the safety rope is fixedly buckled in the safety rope preformed hole 5, then the safety device can start working, when the position needs to be moved back and forth or the length of the supporting rod is not enough, the range of the movement can be enlarged by adjusting the lengths of the first supporting rod 2 and the second supporting rod 3, the second supporting rod 3 and the fixing rod 4 can respectively rotate around the first supporting rod 2 through the rotary drum 9 and the rotary shaft 10 during the movement, thereby the friction between the safety rope and power supply equipment and surrounding objects is reduced, and the abrasion of the safety rope is reduced, thereby play the guard action, the setting of horizontal direction second bracing piece 3 has also increased maintainer's home range, can avoid first bracing piece 2 not only to carry inconveniently because of length overlength, also is difficult to enough safety rope preformed hole 5 at top when the installation, also can lead to the arm of force too big when using, and the easy atress of fixed point takes place the problem of deformation to reduce the potential safety hazard.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
