Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a well head antifriction structure for electric power construction, including fixed plate 1, fixed plate 1 includes canned paragraph 11 and folding section 12, and folding section 12 sets up with 11 articulations of canned paragraph, and 11 and 12 articulated departments of folding section of canned paragraph are provided with corner roller 13, all are provided with a plurality of universal balls 14 on canned paragraph 11 and the folding section 12. The fixed section 11 is provided with an arc-shaped groove 15 on the surface of the universal ball 14, and the arc-shaped groove 15 is arranged towards the folding section 12. The fixed section 11 is provided with a limit plate 3. Fixed plate 1 provides the mounted position for follow-up part, and canned paragraph 11 and ground parallel contact mainly utilize frictional force between canned paragraph 11 and the ground, prevent when bearing the cable, whole fixed plate 1 is pulled towards the well head, has also prevented simultaneously that cable and near well head from producing the friction between the ground. The folding section 12 is used for extending towards the inside of a wellhead and preventing the cable from generating friction between the edge of the wellhead and a well wall when the edge of the wellhead is turned out. The universal ball 14 is arranged to facilitate the movement of the cable on the fixing plate 1, and the sliding friction is replaced by rolling friction, so that the friction force between the cable and the fixing plate 1 is reduced. The fixed plate 1 can be placed at any side position of a well mouth, and simultaneously does not cover the well mouth in a large range, and does not influence the working process of workers going into the well at the well mouth and coming out of the well. The setting of arc wall 15 accords with the cylindric lateral wall shape of cable, and cooperation limiting plate 3 can carry out the spacing of perpendicular and fixed plate 1 axial direction to the cable, prevents that the condition that the cable breaks away from fixed section 11 from taking place.

Referring to fig. 1, in view of the anti-slip fixing of the fixing segment 11, a serration 16 is provided on a side of the fixing segment 11 facing away from the universal ball 14. The fixed section 11 and the folding section 12 are provided with the non-slip mat 2 on the side surface departing from the universal ball 14. The saw-tooth-shaped protrusions 16 increase the friction force of the fixed section 11, so that the fixed section 11 and the ground can be more stable when bearing the cable, and relative sliding cannot be generated. The non-slip mat 2 is further arranged to prevent relative sliding between the fixed section 11 and the ground, prevent relative sliding between the folding section 12 and the well wall, and prevent the phenomenon that the fixed plate 1 is undetermined when the fixed plate 1 bears a cable due to cable movement.

Referring to fig. 1, further, a counterweight plate 4 is arranged at one end of the fixed section 11, which is away from the folding section 12, a hook is arranged on the counterweight plate 4, and a plurality of counterweight blocks 41 are arranged on the counterweight plate 4, which is provided with a hanging ring and is matched with the hook and faces one end of the counterweight plate 4, of the fixed section 11. The counterweight plate 4 is provided with a limiting frame 43 for placing the counterweight block 41. The weight plate 4 is provided with a grinding-proof roller 42, and the grinding-proof roller 42 is erected above the balancing weight 41. The setting of weight plate 4 can prevent that the circumstances that the canned paragraph 11 and ground frictional force undersize lead to canned paragraph 11 to remove from taking place, and balancing weight 41 can increase the pressure of weight plate 4 to ground to make the frictional force increase of weight plate 4 and ground, thereby cooperation canned paragraph 11 increases frictional force, prevent that canned paragraph 11 from removing, and spacing 43's setting can prevent that balancing weight 41 from breaking away from weight plate 4 simultaneously. The anti-grinding roller 42 prevents the cable from interfering with the counterweight block 41, and prevents the counterweight block 41 from wearing the surface of the cable.

The implementation principle of the embodiment is as follows: when the cable is paid off, the fixing plate 1 is firstly placed on a wellhead, and the folding section 12 is folded downwards and extends into the inside of the wellhead. The cable just can be placed in the arc wall 15 on the canned paragraph 11, and limiting plate 3 blocks that the cable breaks away from arc wall 15, and under the effect of a plurality of universal balls 14, the cable wants folding section 12 to slide, through corner roller 13, extends to the well head in, and folding section 12 has avoided the friction between cable and the wall of a well that is close the well head. When the cable is too heavy, the weight plate 4 is hung on the hanging ring of the fixed section 11 through the hook, the counterweight block 41 is placed on the limiting frame 43, and the cable is prevented from being arranged above the abrasion-proof roller 42.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
