Abstract
本发明涉及一种钢管口保护套，该保护套可插入或嵌入用于穿装电缆的钢管处，所述保护套的外径与所述钢管口的内径相匹配，所述保护套远离插入钢管口的一端向外翻折形成防护圈，所述防护圈与所述保护套外壁之间形成可供所述钢管口的周壁插入的夹紧圈口。该护套可以保护穿过钢管的电线或电缆绝缘层不受损伤。
The invention relates to a protective sleeve for a steel pipe mouth, the protective sleeve can be inserted into or embedded in a steel pipe used for piercing cables, the outer diameter of the protective sleeve matches the inner diameter of the steel pipe mouth, and the protective sleeve is far away from the inserted steel pipe One end of the mouth is folded outward to form a protective ring, and a clamping ring opening for insertion of the peripheral wall of the steel pipe mouth is formed between the protective ring and the outer wall of the protective sleeve. The sheath protects the insulation of wires or cables passing through the steel pipe from damage.
Description
Technical field
The present invention relates to a kind of protective sleeve protecting cable, particularly relate to a kind of protective sleeve protecting steel pipe opening place cable.
Background technology
Along with developing rapidly of China's industry constantly expands with scale, each annual a large amount of newly-built electric substation in area of China or the old electric substation of technological transformation.
In the construction of newly-built or technological transformation electric substation, often need by cable through steel pipe, because use amount is large, installation dimension requires high, often cuts steel pipe.But the burr that the steel pipe opening after cutting stays can damage through the electric wire of this steel pipe or the insulating barrier of cable, main manifestations is: when 1) electric wire or cable are through steel pipe, workmen is due to construction needs, electric wire or cable will carry out some and move and bending technique in construction, and skin (outer time serious, internal layer the damages simultaneously) insulation of electric wire or cable is easily damaged on cutting mouth limit; 2) electric wire or cable are through after steel pipe, natural fine jitter and stirring, and steel pipe cutting mouth limit all can produce damage to electric wire or cable insulation friction.
Therefore after electric substation's long-time running; cable through steel pipe opening can cause electric substation's integral insulation hydraulic performance decline because of insulating barrier damage; often there will be the problem such as AC earth, DC earthing, cause interchange or direct-current short circuit time serious, to maintenance work, personnel bring puzzlement.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of protection through the electric wire of steel pipe or the injury-free steel pipe opening protective sleeve of cable insulation.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of steel pipe opening protective sleeve; can insert or embed the steel pipe place for installing cable; the external diameter of described protective sleeve and the internal diameter of described steel pipe opening match; described protective sleeve outwards turns down formation guard ring away from the one end of inserting steel pipe opening, forms the clamping ring mouth that can insert for the perisporium of described steel pipe opening between described guard ring and described protective sleeve outer wall.
In order to effectively increase the tensile force between steel pipe and steel pipe opening protective sleeve, described protective sleeve is the protective sleeve that elastomeric material is made, and the external diameter of described protective sleeve is greater than the internal diameter of steel pipe opening, and one end that described protective sleeve inserts steel pipe has some contraction breach vertically.
Conveniently steel pipe opening protective sleeve is inserted through steel pipe opening smoothly, is provided with import chamfering outside one end of described protective sleeve insertion steel pipe.
In order to make the present invention also can use after electric wire or cable penetrate steel pipe, described protective sleeve outwards turns down the lateral surface forming guard ring and is provided with the otch radially extended.Like this, if in use run into cable penetrate steel pipe, as long as protective sleeve is cut along otch, cable can be inserted in protective sleeve.
When cable wears steel pipe opening protective sleeve, in order to make impaired from the right angle (edge of a knife) on steel pipe opening protective sleeve top of cable, it is the cambered surface of rounding off that described protective sleeve outwards turns down the lateral surface forming guard ring.
The beneficial effect that the present invention brings is:
1) steel pipe opening protective sleeve of the present invention adopts and inserts and the embedded frame mode combined, and steel pipe opening protective sleeve is assemblied on steel pipe opening, and it has good tightening force, is not easy to come off, and installs very convenient convenience;
2) steel pipe opening protective sleeve of the present invention not only can meet cable penetrate steel pipe before use, the use after also can meeting and facilitate cable to penetrate steel pipe.
3) steel pipe opening protective sleeve of the present invention decreases the burr that stay after staff is cut by steel pipe in work progress to through the electric wire of steel pipe or cable insulation damage and the unsafe factor of hurting sb.'s feelings.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Embodiment
The steel pipe opening protective sleeve of the present embodiment; as shown in Figure 1; comprise the protective sleeve 1 that can insert in steel pipe; external diameter and the steel pipe opening internal diameter of protective sleeve 1 match; protective sleeve 1 outwards turns down away from the one end of inserting steel pipe and forms guard ring 3, forms the clamping ring mouth 5 that can insert for the perisporium of steel pipe opening between guard ring 3 and protective sleeve 1 outer wall.
In order to effectively increase the tensile force between steel pipe and steel pipe opening protective sleeve, in the present embodiment, protective sleeve 1 adopts elastomeric material to make, and the external diameter of protective sleeve 1 is greater than the internal diameter of the respective steel mouth of pipe, and one end that protective sleeve 1 inserts steel pipe has multiple contraction breach 2 vertically.
The present embodiment can also do following improvement:
1) conveniently steel pipe opening protective sleeve is inserted through steel pipe opening smoothly, can arrange import chamfering 4 outside one end that protective sleeve 1 inserts steel pipe.
2) when cable wears steel pipe opening protective sleeve, in order to prevent the right angle on steel pipe opening protective sleeve top (edge of a knife) from causing damage to cable, it is the cambered surface of rounding off that protective sleeve 1 outwards turns down the lateral surface forming guard ring 3.
3) protective sleeve 1 outwards turns down the lateral surface forming guard ring 3 and is provided with the otch radially extended.Like this, if in use run into cable when having penetrated steel pipe, as long as protective sleeve 1 is cut along otch, cable can be inserted in protective sleeve.
The present invention is not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop on the protection range of application claims.
