Abstract

The utility model discloses a high-strength impact-resistance grounding pipe. The high-strength impact-resistance grounding pipe comprises a pipe body, a punching head, a steel cap, pins and grounding flat steel; the pipe body is provided with pin holes; the outer wall of the pipe body is provided with reinforcing ribs; the punching head is provided with a first blind hole and a second pin hole; the steel cap is provided with a second blind hole and a third pin hole; the first blind hole of the punching head is sleeved on one end of the pipe body; the second blind hole of the steel cap is sleeved on the other end of the pipe body; one pin connects the punching head with a pipe body pin; the other pin connects the steel cap with the pipe body pin; and the grounding flat steel is welded on the outer wall of the steel cap. The high-strength impact-resistance grounding pipe of the utility model has the advantages of excellent rigidity and high bending strength of the pipe body, sharpness of the cone of the punching head, large effective area of the steel cap, easiness in control of contact points in punching, convenient construction, and improved working efficiency.

Description

The ground pipe of high-strength impact-resistant

Technical field

The utility model relates to the earthing device in lightning-protecting engineering field, especially a kind of ground pipe of high-strength impact-resistant.

Background technology

For preventing thunderbolt, the security of operation of protection electric equipment, high-tension circuit and transformer station, take lightning-protecting engineering to be absolutely necessary, ground pipe is one of important device in lightning-protecting engineering, the ground pipe of prior art, most of 2.7 meters of length, steel galvanized pipe that diameter is 42 millimeters of adopting, to enter ground one end hot extrusion or break into taper, approximately 12 kilograms of weight; The problem that exists is, with the method for hammering with in the buried process of ground pipe, because poor rigidity, the bending strength of ground pipe self are poor, especially encounter tough and tensile earth's surface, ground pipe self can produce bending, and the taper that enters ground one end also can be out of shape, the position that impacts of hammering is tubulose in addition, during hammering, the contact is difficult to control, and has constructional difficulties, ineffective defective.

The utility model content

The purpose of this utility model is the ground pipe of a kind of high-strength impact-resistant of providing for the deficiencies in the prior art, has the body good rigidly, bending strength is high, and the circular cone of drift is sharp, steel cap active area is large, during hammering, the contact is easy to control, has convenient construction, the advantage of increasing work efficiency.

The concrete technical scheme that realizes the utility model purpose is:

A kind of ground pipe of high-strength impact-resistant, its characteristics comprise body, drift, steel cap, pin and grounding flat steel, described body is the tubulose section bar, its two ends radially are respectively equipped with and are vertically " ten " word on pin hole, outer wall and are distributed with reinforcement, drift is the composite-like of cylinder and circular cone, and the axle center of its cylinder is provided with the first blind hole, the first blind aperture to being provided with the second pin hole, and the steel cap is that ladder is round table-like, its axle center is provided with the second blind hole, and the second blind aperture is to being provided with the 3rd pin hole; The first blind hole of described drift is sleeved on an end of body, the second blind hole of steel cap is sleeved on the other end of body, pin is two, wherein one is passed the second pin hole of drift and the pin hole pin joint of body one end, another part passes the 3rd pin hole of steel cap and the pin hole pin joint of the body other end, and grounding flat steel is welded on the outer wall of steel cap.

The utlity model has the body good rigidly, bending strength is high, the circular cone of drift is sharp, steel cap active area is large, during hammering, the contact is easy to control, has convenient construction, the advantage of increasing work efficiency.
