Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, 2 and 3, the wire protection shackle device for the petroleum drilling casing comprises an inner casing 1, wherein the outer part of the inner casing 1 is sleeved into an outer coil 2 in a sliding manner, the upper end and the lower end of the outer coil 2 are both provided with three limiting plates 3 in a circumferential manner and are uniformly fixed with screws, the limiting plates 3 are in contact with the upper end and the lower end of the inner casing 1, six pairs of connecting pieces 4 are uniformly welded on the inner wall of the inner casing 1 in a circumferential manner, each pair of connecting pieces 4 are distributed up and down, a connecting shaft 6 is welded between each pair of connecting pieces 4, a shaft hole is arranged in a pressing strip 5, the connecting shaft 6 is slidably penetrated through the shaft hole, the upper section and the lower section of the connecting shaft 6 are respectively sleeved with a torsional spring 7, two ends of the torsional spring 7 are respectively welded on the connecting pieces 4 and the pressing strip 5, the outermost end of the pressing strip 5 can be kept in a state closest to the inner casing 1 in a natural state by the torsional spring 7, anti-skid convex strips 8 are uniformly arranged on the pressing strip 5, the anti-skid convex strips 5 are integrated with the anti-skid convex strips 8, when the outer wall of the wire protection casing is tightly pressed by the pressing strip 5, through the setting of antiskid sand grip 8, increase layering 5 and thread protector outer wall cooperation resistance, the even welding of inner wall hoop of outer coil 2 has six to support clamp plate 9, it evenly is equipped with six sliding exits 10 to go up the ring on interior sleeve pipe 1, support clamp plate 9 and slide and wear out sliding exits 10 and support pressing contact layering 5, it is square board to support clamp plate 9, sliding exits 10 is square mouthful, when interior sleeve pipe 1 keeps static or counter-rotating, and when outer coil 2 is in the same direction as soon as, support clamp plate 9 and support pressing strip 5 to the inboard direction, make layering 5 compress tightly thread protector outer wall to thread protector direction, the power of exerting is big more, layering 5 supports the outer wall that presses thread protector tighter.

Fig. 1, a first handle 11 is welded on the right side of the top of an external rotation pipe 2, a second handle 12 is welded on the right side of the top of an internal sleeve pipe 1, bolts 13 are inserted into through holes formed in the first handle 11 and the second handle 12 in a sliding mode, nuts 14 are screwed on the bolts 13, oblique tension springs 15 are welded between the heads of the bolts 13, the oblique tension springs 15 are of a tension retraction type, the initial tension retraction force of the oblique tension springs 15 is 100 newtons, and the two bolts 13 are required to be pulled out of the through holes in a natural state of the oblique tension springs 15, so that when the nuts 14 on the two bolts 13 are locked, the oblique tension springs 15 are in a further tension state, and force of applying opposite movement to the first handle 11 and the second handle 12 is strengthened.

The working principle of the embodiment is as follows: when the screw protection sleeve is used, the inner sleeve 1 is sleeved on the outer wall of the screw protection sleeve, the first handle 11 and the second handle 12 are held, the position of the second handle 12 is stabilized, the first handle 11 is rotated towards the direction of the second handle 12, the pressing plate 9 is pressed against the pressing strip 5 towards the inner direction, the pressing strip 5 is enabled to tightly press the outer wall of the screw protection sleeve towards the direction of the screw protection sleeve, the larger the applied force is, the tighter the pressing strip 5 is pressed against the outer wall of the screw protection sleeve, the nut 14 is screwed, the state that the pressing strip 5 is tightly pressed on the outer wall of the screw protection sleeve is kept through the traction force of the inclined tension spring 15, when the pressing strip 5 tightly presses the outer wall of the screw protection sleeve, the matching resistance of the pressing strip 5 and the outer wall of the screw protection sleeve is increased through the arrangement of the anti-slip convex strips 8, at the moment, the first handle 11 is held to rotate the outward rotating pipe 2 along, the pressing strip 5 is more tightly pressed on the screw protection sleeve, until the screw protection sleeve is removed, and the dismounting effect is good.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
