Abstract

The invention discloses a screw-in device for mounting and overhauling a power transmission and transformation device. The screw-in device comprises a bracket, a worm wheel arranged on the bracket, and a worm matched with the worm wheel to drive the worm wheel to rotate, wherein a bearing for supporting the worm wheel is arranged in the worm wheel; the worm wheel is provided with a hexagonal through hole matched with an outer hexagon on a ground anchor; one end of the worm is connected with a first safety shaft coupling for switching the power off in case of overload; the input end of the first safety shaft coupling is connected with a motor serving as an automatic power supply or a rotating handle serving as a manual power source. A worm and worm wheel mechanism is arranged on the bracket, the ground anchor is connected to the worm wheel, and the ground anchor is screwed into or out of the ground surface in a manual way or an electric way through the rotation of the worm wheel; a safety shaft coupling protection mechanism is mainly taken as an integral device for protecting in case of running overload; a direct-current motor is taken as the power source of the integral device. By adopting the screw-in device, a safe screw-in function is realized, the working efficiency is increased, and the working quality is improved.

Description

technical field [0001] The invention belongs to the technical field of power system installation and maintenance, and in particular relates to a screw-in device for installation and maintenance of power transmission and transformation. Background technique [0002] With the development of transmission lines and power grids, electricity consumption by residents and industrial and mining enterprises has become the primary part of power demand, and large and medium-sized power equipment such as power equipment, transmission, distribution, and transformation projects, as well as line maintenance, maintenance, etc. The demand increases, and the reliability requirements of electrical equipment in the power system are getting higher and higher. The increase in the number of operations of power equipment due to power outages and restorations may lead to negative impacts on safety production and personal injury due to long power outages and fatigue operations in power transmission en...
