Abstract
A fatigue resistant kenter shackle comprising: the shackle comprises shackle bodies, a crosspiece and a lock pin, wherein the shackle bodies are matched and fixed with the crosspiece through the lock pin; the shackle comprises a shackle body and a shackle body, wherein the shackle body comprises a left shackle and a right shackle, the left shackle is provided with a zigzag locking device and a mounting hole from top to bottom, and the right shackle is provided with a socket hole and a zigzag locking device from top to bottom; the crosspiece in be provided with oblique pinhole and lockpin, the lockpin pass mounting hole, oblique pinhole and nest hole through fastening screw and fix. The invention has the advantages that the kenter shackle still has better bearing capacity and fatigue life under the condition of ensuring that the thickness is reduced.
Description
Technical Field
The invention relates to the field of anchor chains, in particular to an anti-fatigue kenter shackle.
Background
The kenter shackle is a common chain connecting device and has the advantages of being detachable, capable of passing through an anchor machine and capable of being directly connected with a common chain ring with a stopper. The kenter shackle after heat treatment has the technical characteristics of high strength and high toughness, and can achieve the same breaking strength as a chain. The thickness of the traditional common kenter shackle is about 1.5 times of the diameter of the ring crown, while the thickness of the thin kenter shackle is only 1.3 times, and under the condition that the length, the width and the structural form are not changed, the stress of the thin kenter shackle under the same load exceeds that of the common kenter shackle, so that the stress concentration is caused, and the fatigue life is shortened. The invention provides a novel thin kenter shackle internal form, and the kenter shackle still has better bearing capacity and fatigue life under the condition of ensuring the thickness reduction.
Disclosure of Invention
The invention aims to solve the technical problems and provides an anti-fatigue kenter shackle.
The purpose of the invention is realized as follows: a fatigue resistant kenter shackle comprising: the shackle comprises shackle bodies, a crosspiece and a lock pin, wherein the shackle bodies are matched and fixed with the crosspiece through the lock pin; the method is characterized in that: the shackle comprises a shackle body and a shackle body, wherein the shackle body comprises a left shackle and a right shackle, the left shackle is provided with a zigzag locking device and a mounting hole from top to bottom, and the right shackle is provided with a socket hole and a zigzag locking device from top to bottom; the crosspiece in be provided with oblique pinhole and lockpin, the lockpin pass mounting hole, oblique pinhole and nest hole through fastening screw and fix.
As a preferred technical scheme: the number of teeth of the zigzag locking device can be 2-9; the chamfer angle of the zigzag locking device is r, and r is more than 10.
As a preferred technical scheme: the socket hole, the mounting hole and the inclined pin hole have the same inclination degree.
The invention has the beneficial effects that:
1) a single T-shaped locking device of a common kenter shackle is changed into a plurality of zigzag locking devices, so that stress distribution is more uniform.
2) The number of teeth of the sawtooth-shaped locking device can be 2-9, and different numbers of teeth can be selected according to performance requirements and processing capacity.
Drawings
FIG. 1 is a schematic structural view of the present invention;
description of the drawings: 1. a shackle body; 2. a crosspiece; 3. a lock pin; 4. left shackle; 5. right shackle; 6. a saw-tooth locking device; 7. mounting holes; 8. a socket hole; 9. a bevel pin hole.
Detailed Description
The invention will be further described, but not limited, by reference to the following figures: a fatigue resistant kenter shackle comprising: the shackle comprises shackle bodies 1, a crosspiece 2 and locking pins 3, wherein the shackle bodies 1 are matched and fixed with the crosspiece 2 through the locking pins 3; the method is characterized in that: the shackle comprises a shackle body 1 and a shackle body, wherein the shackle body comprises a left shackle 4 and a right shackle 5, the left shackle 4 is provided with a zigzag locking device 6 and a mounting hole 7 from top to bottom, and the right shackle 5 is provided with a socket hole 8 and a zigzag locking device 6 from top to bottom; the crosspiece 2 is internally provided with an inclined pin hole 9 and a lock pin 3, and the lock pin 3 passes through the mounting hole 7, the inclined pin hole 9 and the socket hole 8 through fastening bolts to be fixed.
The number of teeth 6 of the zigzag locking device can be 2-9; the chamfer angle of the zigzag locking device 6 is r, and r is more than 10. The socket hole 8, the mounting hole 7 and the inclined pin hole 9 have the same inclination.
The invention has the beneficial effects that: the connecting mode of a conventional kenter shackle is adopted, and two ends of the connecting chain link are respectively connected with the chain links and matched through a zigzag locking device. Through in the mounting hole of screwing fastening bolt in the preliminary setting on the crosspiece, ejecting the lockpin of crosspiece inside, when the lockpin imbeds in the nest hole of reserving in the body semicircular ring completely, accomplish the connection of crosspiece and semicircular ring to accomplish the installation of whole product.
1) The core of the invention is that a single T-shaped locking device of a common kenter shackle is changed into a plurality of zigzag locking devices, so that the stress distribution is more uniform.
2) The tooth number of the zigzag locking device can be 2-9, and different tooth numbers can be selected according to performance requirements and processing capacity.
3) In order to prevent stress concentration at the root of the sawtooth and the root of the concave surface, the chamfer angle at the part is at least r & gt 10.
The above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, but not intended to limit the scope of the present invention, and all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
