Description

Distribution line foreign body insulation remover

technical field

The invention relates to a power line maintenance tool, in particular to a foreign matter insulation remover for a power distribution line, which is mainly used for removing foreign matter hanging from a power distribution line.

Background technique

At present, with the development of science and technology and the urbanization of rural areas, the demand for electricity has increased greatly, and the single-circuit line of distribution lines can no longer meet the demand for electricity. The parallel rack has been extended to the suburbs and rural areas while it is popular in cities. Multiple lines of wires are installed side by side on the same pole, the equipment is densely arranged, and the clearance distance of the equipment is reduced. What's more, the clearance distance is less than 20cm, which brings difficulties to live work and greatly increases the difficulty of operation. During the operation, due to the small clearance distance of the equipment, it is difficult for the operators to insulate and shield the live body and the grounding body, and some places cannot even be shielded, which brings great difficulties to the operation and increases the risk factor of the operation. Personal safety cannot be well guaranteed.

The foreign body insulation remover for distribution lines is designed to meet the needs of field operation distribution lines and equipment layout with dense clearance and small clearance distance. In the specific work, it is a routine task to remove foreign matter from the line and equipment while the line is live, and the small clearance distance of the line and equipment is a prominent problem. Foreign matter on lines and equipment in rainy weather can easily cause short circuit or grounding. If not removed in time, it will endanger the operation safety of lines and equipment and reduce the reliability of power supply. At present, there is no tool that can better meet the requirements among the existing traditional insulation tools for live work in power distribution. For example, foreign objects hanging from lines and equipment must adopt the traditional live working method to insulate and shield the lines and equipment and then remove them manually. This will inevitably bring danger to the operators and at the same time reduce work efficiency. It has become a prominent problem that the removal of foreign matter with electricity is dangerous and low in work efficiency.

Contents of the invention

The invention proposes a foreign body insulation remover for power distribution lines aiming at the requirement of small dense spacing between lines and equipment in the field operation, which solves the problem of difficulty in shielding with small spacing between lines and equipment during work.

Technical scheme of the present invention is as follows:

Including the operating rod, the lower part of the operating rod is provided with a fixed seat, the operating handle is movably connected to the fixed seat through the rotating shaft, one end of the linkage plate is connected to the handle, and the other end of the linkage plate is connected to the spring at the inner bottom of the operating rod; The top end is connected to one arm of the needle-nose pliers, the other end of the arm of the needle-nose pliers is fixed to one end of the connection plate, the other end of the connection plate is connected to one end of the pull rod inside the operating rod, and the other end of the pull rod is connected to the bottom of the operating rod The spring at the end; one side of the needle-nose pliers is connected with a hook knife and a blade, and the hook knife and the blade are an upper and lower integrated structure.

The hook knife is disassembled and connected to the jaws of the needle-nose pliers through bolts and nuts.

The top of the hook knife is an arc-shaped apex.

The inner side of the hook knife is provided with a plurality of arc-shaped grooves with different calibers.

The blade of the hook knife protrudes from one side of the needle nose pliers.

A shielding plate is arranged above the fixing seat.

A groove is provided on the shielding plate, and the size of the groove matches the operating handle.

The operating rod is a telescopic telescopic operating rod.

The advantages and effects of the present invention are as follows:

1. The present invention uses needle-nose pliers with insulated heads to meet effective insulation, and achieves the purpose of clamping foreign objects through the opening and closing of the sharp-nose, and uses the blade hook knife installed on the sharp-nose to realize cutting and hooking off foreign objects of lines and equipment. The operation of grasping, pulling and cutting foreign objects can be realized conveniently, so that the force applied during the operation process is accurate, avoiding short circuit or grounding, ensuring a safe distance between the human body and the charged body, ensuring the effective insulation length of the operating tool, reducing It reduces the leakage current flowing through the human body, reduces the live working time, and improves the safety and work efficiency of the power distribution line and equipment live removal of foreign objects. It better adapts to the needs of electric power development, overcomes the reality of small headroom distance of line equipment, guarantees the personal safety of operators, facilitates the work of operators, ensures the safe and smooth operation of operations, and improves the reliability of power supply.

Detailed ways

Example

As shown in Figure 1, it includes an insulating operating rod 1. The insulating operating rod is a sleeve-type telescopic operating rod, which can be adjusted according to the height of the line; On the seat 2, one end of the linkage plate 4 is connected to the handle, and the other end of the linkage plate 4 is connected to the spring 5 at the inner bottom of the operating rod; a shield plate 7 is provided above the fixed seat, which can shield the fallen wires, and the shield plate 7 There is a groove on the top, the size of the groove matches the operating handle, and the operating handle can be stuck in the groove when it is opened; the top of the operating rod is connected with the arm of one side of the needle-nose pliers 8, and the other side of the needle-nose pliers is clamped. The arm is fixed to one end of the connecting plate 9, and the other end of the connecting plate is connected to one end of the pull rod 6 inside the operating rod, and the other end of the pulling rod 6 is connected to the spring 5 at the bottom of the operating rod; one side of the needle-nose pliers is used to disassemble the jaw with bolts and nuts Connect the hook knife 10. Through the detachable connection, the angle of the hook knife can be adjusted according to the angle, and the hook knife can also be replaced. It is flexible to use; The curved shape will not accidentally damage the wire; there are multiple curved grooves with different diameters on the inner side of the hook knife, which can be used in different places. The blade part of the hook knife protrudes from one side of the needle-nose pliers, and when the jaws of the needle-nose pliers are closed, the blade plays a cutting role.
