Description

Overhaul equipment suspension high grounding wire device

technical field

The utility model relates to a grounding wire device for maintenance work on electrical equipment, in particular to a grounding wire device suspended from a high place for maintenance equipment.

Background technique

When working in a power outage, the working body needs to be grounded to ensure the safety and reliability of the workers during the operation, so the requirements for the grounding connection of the grounding wire are very high, and sufficient grounding must be ensured. When working at heights, the connection clip is often used for grounding. At this time, the requirements for the connection clip are very high, and the connection must be reliable. the

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a kind of maintenance equipment suspension high grounding wire device which can improve the reliability of the wiring. the

A device for suspending high-place grounding wires for maintenance equipment, including a connection clip, a connection terminal and an insulating operating rod. The connection terminal includes a ground stake, a movable terminal, and a movable buckle. The ground stake includes a The fixed end is provided with a column on the fixed end of the ground pile. The cross-sectional size of the column is smaller than that of the ground pile. A section of annular groove arranged around the circumference of the column is arranged in the middle or upper part of the column. On the upper part of the annular groove The column is provided with a through hole extending radially along its cross section, a movable terminal and a flat pad are set on the column, a compression spring is arranged between the movable terminal and the flat pad, and a pair of The movable buckle can swing on the vertical surface to be in two positions of upright or horizontal. When the movable buckle is in the horizontal position, the mobile terminal can move up and down along the ground pile column. When the movable buckle is in the upright position, the movable The protrusion at the hinged end of the buckle fits into the groove of the ground pile column to prevent the mobile terminal from moving upward. A through hole is provided at the other end of the movable buckle, and the through hole of the movable buckle is in the upright state. The through holes on the ground pile column are on the same horizontal line, the mobile terminal is located above the groove of the column when the spring is in a normal state, and the spring is at its maximum compression stroke when the mobile terminal moves down to the groove position of the column. the

The maintenance equipment of this structure hangs the grounding wire device at a high place. Using the movable buckle of the utility model, the wiring copper nose of the grounding wire is connected between the flat pad and the column, and the position of the groove on the column is set according to the deformation strength of the spring. , when the mobile terminal is pressed down, it acts on the spring, and the spring acts on the copper nose. The more elastic the spring becomes, the greater the force is, and the more secure the ground connection is. When the mobile terminal is pressed down to the groove, the spring reaches the maximum stroke at this time, so that when the maintenance personnel are on the ground wire, they only need to press the mobile terminal down to the groove position to ensure that the ground wire is firmly connected. The movable buckle in the mechanism can rotate 90° around the fixed axis of the hinge point. When the movable buckle is rotated to the horizontal position, the mobile terminal can move up and down without obstruction. When the mobile terminal is pressed down to the groove position, the movable buckle will be rotated at this time When it reaches the vertical position, the protrusion of the hinged end of the movable buckle is just embedded in the groove position, and at this moment resists the slackness of the spring and reaches the copper nose of the fixed ground wire. There is a round hole at the end of the movable buckle and the ground pile, and the positions of the holes are on the same plane. In this way, when the ground wire is connected, the 5 anti-locks are locked to ensure that the ground wire is not removed and the safety of the staff is ensured. the

A handle is also provided on the mobile terminal. the
