Universal strain clamp anti-falling external member and installation method

Abstract

The invention discloses a universal strain clamp anti-falling external member and an installation method, and belongs to the technical field of electric power protection fitting structures. The universal strain clamp anti-falling external member comprises a front-end self-locking clamp, a pull rod piece and a rear-end buckling clamp, the front-end self-locking clamp is fixed on a front-end strain wire, and the pull rod piece is fixed on the rear-end buckling clamp; the front-end self-locking clamp is fixed at the end part of the front-end self-locking clamp, the rear-end buckling clamp is fixed at the end part of the rear-end U-shaped ring, the PT adjusting plate or the PD extension plate, the two groups of pull rod pieces are arranged in bilateral symmetry and are respectively connected with the left and right ends of the front-end self-locking clamp and the rear-end buckling clamp, and the protective hardware fitting for bearing the mechanical tension of the wire is only composed of three parts. The tightening clamp adopts an inner taper sleeve and an outer taper sleeve, is light and simple, is convenient to install, and is installed without depending on a steel anchor ring of a wire tension crimping pipe, so that the anti-falling external member for the strain clamp has better universality.

Description

technical field [0001] The invention relates to the technical field of electric power protection fittings structure, in particular to a general-purpose strain clamp anti-falling kit and an installation method. Background technique [0002] The wire crimping tube in the running line, due to insufficient pressure during hydraulic crimping, the deformation of the mold did not reach the proper compression ratio, or the connection of new and old wires, inadequate purification work, and insufficient tightening force of the bolts on the drainage plate of the tension clamp Problems such as crimping tube pulling out, breakage, heat and burns may cause the wire to fall to the ground, and the power supply of the line will be interrupted. Especially the tension-type crimping tubes of transmission lines spanning high-speed railways, highways, rail transit and important municipal facilities, once broken, it will cause a series of serious secondary hazards. Most of the current protective ...

And because it relies on the two screws connected in series to the U-shaped pull ring of the steel anchor ring of the steel anchor ring of the wire tension compression to withstand the tension of the wire after penetrating the earring holes on both sides, it will always maintain a moderate tension state, and in case the wire is tension resistant There will be no impact force when the connection is dropped; however, since the U-shaped pull ring needs to be installed through the steel anchor ring of the wire tension-resistant connection pipe, in practical applications, especially some ultra-high voltage line equipment, due to the force requirements Different, so the diameter of the U-shaped pull ring may not be able to pass through the steel anchor ring of the wire tension crimping pipe after the diameter is increased, resulting in the failure of the original protective device to be installed smoothly, and it cannot be installed and used with other fixtures that do not have a steel anchor ring structure
