A grounding device for an insulated bucket arm car

Abstract

The invention relates to a grounding device for an insulated bucket arm truck, which includes three parts: an automatic wire take-up device, a grounding wire and a grounding body. The blue is firm and ensures reliable connection; the housing is provided with a wire inlet and outlet, and a wire take-up reel is arranged inside the housing. A retraction spring is installed at one end, and a limit gear is installed at the other end of the bearing. The limit gear cooperates with the limit ratchet and the limit spring. The limit gear is installed on the bearing of the take-up wheel, and the limit ratchet is installed on the fixed shell. The coil spring defines the working position through the fixed column on the shell; the grounding body includes a grounding hoop, a grounding handle, and a manual fastener. The grounding hoop is connected to the power line pole tower, and is fixed firmly by the manual fastener. outside of the hoop.

Description

technical field [0001] The invention belongs to the technical field of electric power construction equipment, and in particular relates to a grounding device for an insulating arm truck. Background technique [0002] With the continuous improvement of safety production requirements, the requirements for the safety of people, tools and vehicles in live work are also continuously improved, especially the use, maintenance and maintenance of live work vehicles put forward higher requirements for safety. [0003] At present, during the live work of the intermediate potential method, it is required that the insulated bucket truck must use a qualified grounding wire, and the installation and use of the grounding wire must be standardized. The hardening rate of the ground is relatively high. Due to the limitation of the radius of live work, no suitable location for installing the grounding body can be found. Hardened ground such as cement floor and prefabricated concrete ground cann...

Problems solved by technology

[0003] At present, during the live work of the intermediate potential method, it is required that the insulated bucket truck must use a qualified grounding wire, and the installation and use of the grounding wire must be standardized. The hardening rate of the ground is relatively high. Due to the limitation of the radius of live work, no suitable location for installing the grounding body can be found. Hardened ground such as cement floor and prefabricated concrete ground cannot be installed with the grounding body, which has caused a major hidden danger to the safety of live work. For this technical problem that plagues the production line of live work; this is the deficiency of the existing technology
