Example Embodiment

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] An insulated torque wrench for live fastening vibration isolator bolts, comprising a sleeve tube 4, the inner hole of the sleeve 4 is an inner hexagonal cavity 4-3 that matches the nut of the vibration isolator bolt, and the middle part of the sleeve 4 is outside The surface is provided with a ratchet wheel 4-1. The diameter of the ratchet wheel 4-1 is the same as the outer diameter of the sleeve 4. The outer ring of the ratchet wheel 4-1 is fixedly sleeved with a circular insulating washer 5, and the thickness of the insulating washer 5 is the same as the teeth of the ratchet wheel 4-1. The thickness in the vertical direction is the same. An insulating disk 3 with a handle 3-2 is installed on both sides of the insulating washer 5, and the insulating disk 3 is movably connected with the insulating washer 5 and the sleeve 4. The insulating plate 3 is divid...

Abstract

The invention discloses an electrified fastening antivibrator bolt insulation torsion wrench. The electrified fastening antivibrator bolt insulation torsion wrench comprises a sleeve with an inner hexagonal cavity and insulation discs provided with a handle respectively and used for driving the sleeve to rotate; a ratchet is arranged at the outer surface of the middle of the sleeve; an annular insulation gasket is fixedly sleeved outside the ratchet; the insulation discs are respectively arranged at two sides of the insulation gasket; the insulation discs are of a driving insulation disc and a support insulation disc respectively; the driving insulation disc is hinged to a pawl matched with the ratchet; the driving insulation disc, the support insulation disc, the insulation gasket and the sleeve are movably connected; the handle of each of the driving insulation disc and the support insulation disc is connected with a lengthened insulation arm. The electrified fastening antivibrator bolt insulation torsion wrench can be electrified for operation, multiple inconveniences of a user caused by the power outage operation are avoided, the operation is easy, the safety is high, and the reliable operation of a power system and the personal safety of operation personnel are ensured.

Description

technical field [0001] The invention relates to a tool used in the field of electric power construction, in particular to a torque wrench. Background technique [0002] In order to prevent the transmission line from resonating due to the breeze, which will cause accidents such as fatigue and broken strands of the transmission line, anti-vibration devices are installed on the power transmission line. Because the anti-vibration device is exposed to the field for a long time, it is easily affected by various factors, so the bolts of the anti-vibration device are prone to loosening. When the bolts of the anti-vibration device are not fastened in time, it is easy to cause the anti-vibration device to deviate from the original installation position and cause the phenomenon of displacement. Once the anti-vibration device moves, it will not only fail to prevent vibration, but will also cause new hazards: such as vibration and galloping of the transmission line, fatigue and broken s...
