For example, the invention of publication number cn202310622627.X discloses an energy-saving suspension clamp, it drives the rotary drum to rotate through the frictional force generated by the pressing plate when the wire is pulled, thereby the rope body is wound to the outside of the rotary drum in a linkage way, at this time, the rope body is stored and wound to drive the connecting plate connected to move vertically, the pressure of the 'U' -shaped hanging ring is given to the 'U' -shaped hanging ring, so that the 'U' -shaped hanging ring extrudes the ejector rod, the ejector rod is retracted by the compression potential energy of the spring, and the elastic potential energy of the spring is rebounded by the elastic potential energy of the spring after the pressure is withdrawn, so as to be clamped between the groove and the sliding ring, thereby completing the self-locking effect.
The scheme is that the wire is fixed in-process and has the problem, firstly, when the suspension clamp is actually installed, the outside of the wire needs to be wound with an aluminum protective layer to avoid the wire from being worn in the suspension clamp, and the friction force between the aluminum protective layer and the rotating drum is small, so that the rotating drum cannot rotate when the wire is pulled. Secondly, the way of pulling the wire to rotate the drum is laborious and dangerous because the wire is heavy and is working aloft when installed. Meanwhile, the rope body is wound on the rotating drum and is in contact with the aluminum protective layer, and the high-voltage wire is very high in working voltage, and the aluminum protective layer is further wound on the part positioned in the wire clamp, so that the temperature of the part is higher than that of the wire of the exposed part (the temperature of the exposed part of the high-voltage overhead wire is 60-80 ℃), and the rope body is damaged when the part positioned in the wire clamp is in contact with the rotating drum and the rope body, so that the maintenance difficulty is increased. Therefore, in order to solve the above problems, a nano aluminum alloy suspension clamp is proposed.
