Abstract

The utility model discloses a slideway typed grounding pole which is provided for overcoming the shortcomings of easy to violate the safety working regulations in the operation of installing or disassembling the grounding line to the high voltage overhead conductors, and the physical strength consumes are large that are in the existing technology. The utility model contains a pole and a grounding hook which is fixed with grounding line. An insulated hook is arranged on the top of the pole. A lifting sleeve which can slide along the pole is arranged on the pole. An insulated rope passed by the upper and lower pulleys that are arranged inside the pole, and connects with the lifting sleeve. The shank socket of the grounding hook is on the tope of the lifting sleeve. Because the grounding hook is arranged on the top of the lifting sleeve which can slide along the pole, and the ground hook passes by the insulated rode of the upper and lower pulleys, and connects with the lifting sleeves, in the process of operation, the pole forms a supporting point that is used for suspending. The hand insulated rope drives the grounding hook, which is fixed with grounding line, to lift and down. Under the condition of no grounding line and the grounding hook has no weight, the utility model can make the grounding hook hang on the high voltage overhead conductors or take off the high voltage overhead conductors easily, and the human body does not connect with the grounding line, which makes the utility model easy and convenient to use with high efficiency and saving labor.

Description

The chute type earth brace

Technical field

The utility model belongs to instrument, specifically a kind of special-purpose ground connection earth brace of using for high-voltage conducting wires demolition, installation earth connection.

Background technology

On the high voltage overhead lead, be hinged with or dismantle in the construction of earth connection, existing method is the ground connection hook that is inserted with dead earth line above it at the top of microscler earth brace, staff's both hands are held earth brace, ground connection hook and earth connection held up to push away together be suspended on the high voltage overhead lead, drop-down then earth brace and hook break away from; After construction is finished, will lift on the earth brace again, make the ground connection hook be inserted in the earth brace top again, take off the ground connection hook after pushing away earth brace on again.Because the weight of earth connection self is bigger, held up together to adorn to hang on the high voltage overhead lead and for can be with long earth brace that own wt is very big earth connection and earthy ground hook and taken off from the high voltage overhead lead, operating personnel lift on also partly being held in the hand in the lump hanging down of earth connection when holding earth brace, then earth brace, hook and the earth connection of 4-5 kilogram have been held up together, be suspended on the high voltage overhead lead that highly reaches 1.8-2.4 rice, take off from the high voltage overhead lead again with same mode of operation.Human body contacts with earth connection in operating process like this, and it is very big not only to expend muscle power, and has seriously violated the regulation about forbidding operating personnel to contact with earth connection in the electrical safe working order, has brought very big hidden danger to safety in production.

The utility model content

Technical problem to be solved in the utility model is, overcoming prior art is hinged with on the high voltage overhead lead or dismantles in the earth connection operating process, human body contacts breach of security working regulation with earth connection, and expends the big shortcoming of muscle power, and a kind of chute type earth brace is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: earth brace comprise earth brace the body of rod, be fixed with the ground connection hook of earth connection, the body of rod top of earth brace is connected and installed with insulated hook, the lifting cover that can slide up and down along the body of rod is installed on the body of rod, the insulation rope is walked around the upper and lower pulley of installing in the body of rod ringwise, is connected lifting and puts; The shank socket of ground connection hook is on the top of lifting cover.

The utility model also has following technical characterictic:

The shank socket of described ground connection hook is on the top of lifting cover, is that the side at the lifting cover is provided with protruding, on wear vertical wooden fork mouth ground rhampotheca seat be fixed on protruding, the shank of ground hook is inserted in the seat ground rhampotheca seat, the fixing lateral pin of shank is inserted in the vertical wooden fork mouth;

Being connected of described insulation rope and lifting cover is that the body of rod one side at the nearly earth brace of described ground rhampotheca seat is provided with the ear frame, is bearing on the ear frame with pin in the middle part of the horizontal lever pawl; Ear frame one side that lifting puts is provided with ring set, and vertical pull bar passes ring set, and its top is connected with the nearly earth brace one end hinge of lever pawl, and the lower end of vertical pull bar is provided with the pull bar ring, the two ends of restricting of insulating tie up to the pull bar ring about; The upper end of stay cord is fixed on the lower end of ground rhampotheca seat, and its lower end is fixed on the centre position of insulation rope; Be provided with vertical elongated slot near ear frame place on ground rhampotheca seat, the pawl point of the lever pawl other end inserts vertical elongated slot, can be squeezed on the handle of ground connection hook when drop-down at vertical pull bar;

Described lifting cover slides up and down along the body of rod of earth brace, is to be equipped with at lifting cover internal support to lean against the roller that body of rod surface slides up and down;

The body of rod of described earth brace is a rectangular tube;
