The utility model content:
The purpose of this utility model provides a kind of bolted on connection formula cable protection device, general protection, and safety is firm, and difficult drop-off solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: bolted on connection formula cable protection device is arranged in the oil pipe; comprise cable and protect end, strain relief clamp end, vulcanized rubber, coupling bolt; vulcanized rubber is provided with the route protection groove; vulcanized rubber is arranged on cable and protects in the end; cable protects between end and the strain relief clamp end and links together by coupling bolt, and cable protects end and is complementary with inner chamber and the oil pipe external diameter that the strain relief clamp client link constitutes together.
The bind mode that cable protects between end and the strain relief clamp end is: can at one end be connected through the hinge, the other end connects by coupling bolt; Also can all connect at two ends by coupling bolt.
Cable protection groove and liquid controling pipe line groove and test cable are set on the vulcanized rubber in cable protects end protect groove, the protection of cable and liquid controling pipe line is solved simultaneously.
Cable protects end and adopts T type bolt and nut and slip-knot bolt arrangement with the strain relief clamp client link, this structure by ship and resell on another market (hinge), T type nut, and bolt form, when assembling, pass the pin hole that cable protects end and strain relief clamp end with shipping and reselling on another market, adopt welding manner, to ship and resell on another market and protect end points weldering with cable and link together, and polish with the angle grinding machine at postwelding.Bolt is linked in the T type nut, and with the bolt end with riveting gun with the thick 1mm of end pier about, since at T type nut screw thread end by one section reaming section, bolt also can all fall back in the T type nut like this, simultaneously, owing to thickened portion is arranged at bolt head, exempted the possibility that bolt in use drops out, make whole none loose mail of cable guard exist.Adopt the slip-knot bolt, straight pin is inserted in the slip-knot bolt hole, the formation linkage rotates the slip-knot bolt during installation, nut is pressed on the connector get final product.
Adopt the utility model, vulcanized rubber protective layer in steel body groove makes and can protect cable not crush injury again in the jail that cable guard can be fixed cable.Because liquid controling pipe line groove and test cable protection groove adopt the sulfuration of rubber on guard shield steel body to form, and have both increased liquid controling pipe line and the test cable frictional force on tubing wall, have effectively protected liquid controling pipe line, test cable not to be extruded distortion again, destroy.
