Description

A insulating bar for hanging earth connection fast

Technical Field

The utility model relates to an insulated operating rod instrument field specifically is an insulated operating rod for articulating earth connection fast.

Background

The transmission line and the tower are influenced by factors such as external force damage, animal influence, natural disasters and the like in the long-term operation process, and the defects of different degrees often appear. The power failure maintenance equipment has the advantages that most of the power failure maintenance equipment can only perform power failure operation during the power failure maintenance process, the personal safety of operating personnel is guaranteed in order to avoid electric shock accidents in the power failure maintenance process, and the power failure maintenance equipment still needs to be hung with a short-circuit grounding wire on the premise of strictly executing a power failure and transmission management system. The hanging connection of the grounding wire is a reliable safety measure for preventing sudden incoming calls in a working place, and meanwhile, residual charges of a disconnected part of the equipment can be completely discharged due to grounding, so that the induction voltage possibly generated by power failure equipment is prevented, and the life safety of line maintenance personnel is protected.

At present, in the operation process of installing the grounding wire by using a common insulating operation rod, the head of the insulating operation rod is in a non-fixed mode, so that the electric clamp is easy to fall off in the hanging process, and the angle of the electric clamp is easy to change in the operation process. Therefore, the time for installing the grounding wire is long, and the preparation time for power failure operation is further long, so that the power failure operation time is prolonged, and huge economic and social losses are caused. Therefore, it is urgent to design an insulating operating rod for fast hanging the grounding wire.

SUMMERY OF THE UTILITY MODEL

The utility model provides an insulating bar for articulating earth connection fast, the effectual big problem of the current insulating bar operation degree of difficulty of having solved, this device adopts the mobile clamping piece of F "type to press from both sides and grabs the structure and can add the structure of action bars length, reaches the purpose that swift high efficiency articulated the earth connection.

In order to achieve the above object, the utility model discloses a technical scheme specifically as follows:

the utility model provides an insulating bar for hanging earth connection fast, includes nested outer pole 1 and interior pole 2 each other, its characterized in that: install spring 6 between the outer bottom surface of outer pole 1 inner bottom surface and interior pole 2, install base 3 on outer pole 1, install operating handle 4 through base 3, install connecting rod 5 between operating handle 4 and interior pole 2, the clamping piece lantern ring 8 is installed down at outer pole 1 terminal surface, and it has lower clamping piece 10 to weld on it, installs the clamping piece lantern ring 7 at the terminal surface of interior pole 2, and it has last clamping piece 9 to weld on the clamping piece lantern ring 7.

An extension rod 11 is arranged on the end face of the outer rod 1 through a nut pair 13, and an extension rope 12 is fixed on the connecting rod 5.

The diameter of the upper clip lantern ring 7 is smaller than the inner bore diameter of the outer rod 1.

The upper clamping piece 9 is a T-shaped clamping piece.

The utility model has the advantages that: the F-shaped clamping piece clamps the power connection clamp of the grounding wire, so that the grounding wire does not fall off or the power connection clamp turns in the hanging process, and the efficiency of hanging the grounding wire is improved. Meanwhile, when the distance is short, only the operating rod is used, the lock locks the operator to enable the lock to be in a normally closed state, so that the grasping force is saved, and the wire end can be conveniently and accurately hooked; when the distance is far, the purpose of quickly and efficiently hanging the grounding wire can be achieved by using the extension rod and the switch extension rope

FIG. 3 is a top view of the lower clip;

shown in the figure: the device comprises an outer rod 1, an inner rod 2, a base 3, an operating handle 4, a connecting rod 5, a spring 6, an upper clamping piece lantern ring 7, a lower clamping piece lantern ring 8, an upper clamping piece 9, a lower clamping piece 10, an extension rod 11, an extension rope 12 and a nut pair 13.

Detailed Description

The technical solution of the present invention is further described by the following specific embodiments with reference to the accompanying drawings:

example 1

According to the actual work requirement on site and the convenient transportation and carrying, the insulated operating rod is made of epoxy resin, the diameter of the operating rod is 30mm, the total length of the operating rod is 3000mm, the operating rod is divided into two parts, namely a clamping rod and an extension rod 11, each 1500mm, and an M14 bolt with the length of 20mm and an M14 nut with the depth of 20mm are used for connection.

The clamping jaw rod consists of an outer rod 1 and a clamping inner rod 2, and a spring 6 is arranged between the inner bottom surface of the outer rod 1 and the outer bottom surface of the inner rod 2. The spring 6 is connected with the operating handle 4 according to the lever principle, and a connecting rod 5 is arranged between the operating handle 4 and the inner rod 2. The end surface of the outer rod 1 is provided with a lower clamping piece lantern ring 8, a lower clamping piece 10 is welded on the lower clamping piece, the end surface of the inner rod 2 is provided with an upper clamping piece lantern ring 7, and an upper clamping piece 9 is welded on the upper clamping piece lantern ring 7. Because the diameter of the upper clamping piece lantern ring 7 is smaller than the inner bore diameter of the outer rod 1, and the upper clamping piece 9 is a T-shaped clamping piece, the upper clamping piece 9 can be coincided with the lower clamping piece 10 through movement.

During the specific use, press from both sides and grab interior pole bottom and be spring 6, when gripping operating handle 4, when the connecting rod 5 of being connected with operating handle 4 promoted interior pole 2 and removed, the extrusion spring, interior pole 2 remove and drive clamping piece 9 and the coincidence of lower clamping piece 10 for press from both sides and get the earth connection. When the operator is released, the spring 6 provides restoring acting force, the inner rod 2 moves upwards, and the upper clamping piece and the lower clamping piece are released. The diameter of the outer clamping and grabbing rod is 30mm, the length of the outer clamping and grabbing rod is 1500mm, the diameter of the inner clamping and grabbing rod is 26mm, the length of the inner clamping and grabbing rod is 1400mm, and the length of the spring is 150 mm.

The 'F' -shaped clamping head is formed by an upper clamping piece and a lower clamping piece, the clamping pieces are made of stainless steel, the diameter of a lantern ring of the lower clamping piece is 31mm, the length of each clamping piece is 100mm, the diameter of a lantern ring of the upper clamping piece is 27mm, the length of an extension rod is 50mm, and the length of each clamping piece is 100 mm.

When using extension rod 11, it is inconvenient to use operating handle 4, so adopt extension rope 12 to be connected with connecting rod 5, the effect of extension rope 12 is the same with operating handle 4's effect, at the in-process of pulling for upper and lower clamping piece coincide. After the extension rope 12 is loosened, the upper clamping piece and the lower clamping piece are separated under the action of the spring 6.
