the chain dropping prevention shackle comprises a shackle body, a pin shaft, a nut and a protective cover, wherein the shackle body is of a U-shaped structure, two penetrating mounting holes are formed in two ends of the opening side of the shackle body, the pin shaft is of a bolt structure, a hexagon nut is arranged at one end of the pin shaft, an external thread is arranged at the other end of the pin shaft, and the protective cover is provided with an internal thread and can be sleeved at the external thread end of the pin shaft; connecting chains are fixedly arranged on the hexagon nut end, the nut and the protective cover of the pin shaft, and the pin shaft, the nut and the protective cover are not separated from the buckle body through the connecting chains;
when the safety protection cover is used, the pin shaft penetrates through the mounting hole of the buckle body, the nut is mounted on the thread of the pin shaft, and the protection cover is mounted on the thread of the pin shaft behind the nut.
Further, still include the split pin, sell epaxial external screw thread end and be equipped with the first locking hole that radially link up, be equipped with the second locking hole that radially link up on the safety cover, the split pin passes first locking hole, second locking hole locking shackle and safety cover.
Furthermore, a connecting rope is fixedly arranged on the cotter pin, and the other end of the connecting rope is fixed on a connecting chain at the hexagonal nut end of the pin shaft, the nut or the protective cover.
The utility model has the advantages that:
the shackle of the utility model can replace the conventional shackle to carry out hoisting operation; when the hoisting is finished, the cotter pin, the nut and the pin shaft can be detached at will, and the situation that small parts such as the nut or the pin shaft fall into a wellhead or fall into sundries and cannot be found is avoided, so that the probability of causing complex site construction is greatly reduced.

Furthermore, unless otherwise indicated, the drawings are intended to be illustrative of the structural configurations described herein and are not necessarily drawn to scale.
Fig. 1 is a schematic structural view of an anti-drop chain shackle for a drilling site according to an embodiment of the present invention;
Detailed Description
First, it should be noted that the specific structures, features, advantages, etc. of the present invention will be described in detail below by way of example, but all the descriptions are only for illustrative purpose and should not be construed as forming any limitation to the present invention. Furthermore, any single feature described or implicit in any embodiment or any single feature shown or implicit in any drawing may still be combined or subtracted between any of the features (or equivalents thereof) to obtain still further embodiments of the invention that may not be directly mentioned herein. In addition, for the sake of simplicity, the same or similar features may be indicated in only one place in the same drawing.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the product of the present invention is used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The present invention will be described in detail with reference to fig. 1.
As shown in fig. 1, the chain dropping prevention shackle for a drilling site provided by the embodiment includes a shackle body 1, a pin shaft 3, a nut 5 and a protection cover 6, wherein the shackle body 1 is of a U-shaped structure, two through mounting holes 101 are formed in two ends of the opening side of the shackle body, the pin shaft 3 is of a bolt structure, one end of the pin shaft is a hexagon nut, the other end of the pin shaft is provided with an external thread, and the protection cover 6 is provided with an internal thread which can be sleeved on the external thread end of the pin shaft 3; in the present embodiment, the pin shaft 3 is connected to the buckle body 1 through a first connecting chain 2, the nut 5 is connected to the buckle body 1 through a second connecting chain 8, and the protective cover 6 is connected to the second connecting chain 8 through a third connecting chain 9;
when the buckle is used, the pin shaft 3 penetrates through the mounting hole 101 of the buckle body 1, the nut 5 is mounted on the thread of the pin shaft 3, and the protective cover 6 is mounted on the thread of the pin shaft 3 behind the nut 5.
Still include split pin 7, the external screw thread end is equipped with the first locking hole 301 that radially link up on round pin axle 3, be equipped with the second locking hole 601 that radially link up on the safety cover 6, split pin 7 passes first locking hole, second locking hole locking shackle and safety cover 6.
The split pin 7 is fixedly provided with a connecting rope 4, the other end of the connecting rope 4 is fixed on a connecting chain at the hexagonal nut end of the pin shaft 3, the nut 5 or the protective cover 6, and in the embodiment, the other end of the connecting rope 4 is fixed on the second connecting chain 8.
