Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a frock is arranged to boat sling trend of space swing pulley, including setting up prevent pendulum rod 2 on main arm body 5, the terminal surface rotates before the main arm body 5 and is provided with corner pulley 6, main arm body 5 left side is run through and is provided with swivel mount 4, swivel mount 4 inside is rotated and is provided with hollow rotating shaft 7, hollow rotating shaft 7 left side through connection has

guide block

3, 3 inside rotations of guide block are provided with head pulley 9, prevent that pendulum rod 2 rotates and connect in 3 downside of guide block, prevent 2 downside body coupling of pendulum rod and have into spool 1, it is not good to have solved boat sling swing pulley atress structure in the past, influence the problem that rope 10 used.

The specific working principle is as follows: the main arm body 5 is fixed at a designated position, and the rope 10 sequentially passes through the wire inlet pipe 1, the head pulley 9, the hollow rotating shaft 7 and the corner pulley 6 and then is led out; because the section of the rope groove is of a semicircular structure, and the circle center of the semicircle is on the same straight line with the central line of the hollow rotating shaft 7, the rope 10 cannot generate relative friction with the inner wall of the hollow rotating shaft 7 even if swinging;

when the rope 10 swings, the anti-swing rod 2 is connected with the guide block 3 in a rotating mode, the rope 10 can swing in the left-right direction, the hollow rotating shaft 7 is connected with the main arm body 5 in a rotating mode, the rope 10 can swing in the front-back direction, and therefore load stress on the rope 10 is free of a force arm relative to the hollow rotating shaft 7, and therefore bending moment cannot be generated to affect normal actions of the anti-swing rod 2 and the whole tool.

The annular side surfaces of the corner pulley 6 and the head pulley 9 of the utility model are both provided with rope grooves, and ropes 10 for hoisting are placed on the rope grooves; the section of the rope groove is of a semicircular structure, and the circle center of the semicircle is on the same straight line with the center line of the hollow rotating shaft 7, so that relative friction between the rope 10 and the inner wall of the hollow rotating shaft 7 can be avoided even if the rope 10 swings, and the resistance of the rope 10 is reduced.

The right side of the guide block 3 of the utility model is provided with a limit block 8, and the edge part of the guide block 3 is provided with a shading strip 31 for guiding the rope 10; the inlet pipe 1 is a hollow structure, and friction between the rope 10 and the inner wall of the inlet pipe 1 is reduced.

The utility model discloses an inside pivot that is provided with of corner pulley 6, and fixedly connected with prevents the sunshade that rope 10 breaks away from in the pivot for rope 10 direction, and prevent that rope 10 from breaking away from the effect of corner pulley 6.

The rotating connection part of the anti-swing rod 2 and the guide block 3 of the utility model is provided with a movable shaft 21 in a penetrating way, and the axle center of the movable shaft 21, the left side tangent line of the head pulley 9 and the central line of the inlet pipe 1 are on the same straight line; thus, the rope 10 is aligned with the axis of the movable shaft 21, the left tangent of the head pulley 9, and the center line of the inlet pipe 1, and friction between the rope 10 and the inlet pipe 1 and the head pulley 9 is reduced.

As an embodiment of the present invention: step one, threading: the rope 10 sequentially passes through the wire inlet pipe 1, the head pulley 9, the hollow rotating shaft 7 and the corner pulley 6 and then is led out; step two, preventing the swing rod 2 from deflecting: when the rope 10 is subjected to swinging force in the left-right direction, the axis of the movable shaft 21, the left tangent of the head pulley 9 and the center line of the inlet pipe 1 are on the same straight line, the rope 10 deflects left and right to drive the inlet pipe 1 and the anti-swing rod 2 to deflect left and right, and the inlet pipe 1 and the anti-swing rod 2 are used for guiding the rope 10 in a left and right offset manner; step three, deflecting the guide block 3: when the rope 10 swings back and forth, the guide block 3 and the main arm body 5 are twisted, the rope 10 between the corner pulley 6 and the head pulley 9 is subjected to torsion, because the corner pulley 6 on the main arm body 5 and the head pulley 9 are on the same horizontal plane, a tangent line at the top of the corner pulley 6, a central line of the hollow rotating shaft 7 and a tangent line at the top of the head pulley 9 are all on the same straight line, when the anti-swing rod 2 drives the head pulley 9 to swing back and forth under the action of external force, the hollow rotating shaft 7 rotates in the main arm body 5, and the load on the rope 10 is stressed to have no arm relative to the hollow rotating shaft 7, so that the normal action of the anti-swing rod 2 cannot be influenced by the bending moment, and the hollow rotating shaft 7 does not contact and rub with the rope 10; step four, the torsion of the rope 10 is buffered: in the third step, the corner pulley 6 and the head pulley 9 have a certain distance therebetween, so that the torsion of the rope 10 can be buffered.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
