Problems solved by technology

A typical example is the Quebec Hydropower Research Institute in Canada, which has successfully developed an inspection and maintenance robot with the function of overcoming obstacles. The robot uses a single arm to carry a bolt fastening device for maintenance operations. The connection between the bolt fastening device and the bolt mainly relies on The self-adaption of the device itself is not outstanding, and it can only output a certain torsional moment when adjusting the articulated working arm. Therefore, the bolt fastening device has certain limitations in practical use.

Abstract

The invention provides an overhead high tension transmission line tensile wire clamp drainage crab bolt fastener. The fastener comprises a driving motor and a transmission case, wherein the transmission case comprises a transmission mechanism connected with the driving motor for transmitting torque, a butt joint mechanism used for aligning and cooperating with a bolt, and a buffer mechanism used for partially pressing a nut. According to the invention, the requirement for a work arm is quite low, the operation is simple and convenient, the fastener can be applied to a fastening tensile wire clamp drainage crab bolt and can also fasten bolts of other hardware fittings, what is needed is only to replace an internal hexagonal sleeve according to the models of the bolts, the mounting and dismounting of the internal hexagonal sleeve are convenient, and the practical value is quite high.

Description

technical field [0001] The invention relates to a bolt fastening device, in particular to a bolt fastening device for an overhead high-voltage transmission line tension clamp drain plate. Background technique [0002] The working environment of overhead high-voltage transmission lines is relatively harsh. Due to the perennial exposure to the wild, it is very vulnerable to environmental and geographical factors. Some factors such as icing, breeze vibration and other factors will cause the wire to vibrate, which in turn will lead to the loosening of the bolts of the strain clamp drainage plate. In this way, the resistance will increase due to inaccurate contact. Once the resistance increases, the temperature of the drain plate will rise accordingly, and the oxidation of the contact surface will be strengthened. As the temperature continues to increase, the drain plate will be burned. If there is a disconnection accident, it will have a great impact on the safe and stable oper...
