Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1-4, a self-locking lifting appliance comprises a lifting hook 1 and a stop lever 2, wherein the lifting hook 1 comprises an L-shaped hook rod 3, an open slot 4 is arranged at the upper end of the hook rod 3, an inclined upward guide rod 5 is arranged at the lower end of the hook rod 3, and the hook rod 3 and the guide rod 5 are of an integral structure. The upper end of the stop lever 2 is arranged in the open slot 4 and is hinged with the lifting hook 1, and the lower end of the stop lever 2 is arranged at the bottom of the lifting hook 1.

The two sides of the lifting hook 1 are both fixed with a locking rod 6, one end of the locking rod 6 is hinged to the lifting hook 1, the other end is provided with a locking hook 7, the locking rod 6 and the locking hook 7 are of an integral structure, one end, far away from the locking rod 6, of the locking hook 7 is a first arc-shaped end 8, a lower limiting block 9 is fixed on the lifting hook 1 on the lower side of the locking rod 6, the lower limiting block 9 is used for supporting the locking rod 6, one end, far away from the locking rod 7, of the locking hook 7 is limited to rotate downwards due to self weight, locking blocks 10 matched with the locking hook 7 are fixed on the two sides of the stop lever 2, one end, close to the locking rod 6, of the locking block 10 is a second arc-shaped end 11, an upper limiting block 12 is fixed on the stop lever above the locking block 10, and the upper limiting block 12 is used for limiting the upward rotation angle, far away from one end, far away from the locking hook 7, of the locking rod 6. One end of the lock rod 6 far away from the lock hook 7 is connected with a pull rope 13, and the upper end of the stop lever 2 is provided with a hanging hole 14.

The application method of the embodiment comprises the following steps: the lifting appliance is connected with a lifting device through a lifting hole 14, a lifting rope or a wire is placed in a lifting hook 1 and then lifted, the lifting hook 1 and a stop lever move oppositely under the action of gravity, when a locking hook 7 reaches the position of a locking block 10, a second arc-shaped end 11 of the locking block 10 pushes a first arc-shaped end 8 of the locking hook 7 to move upwards, so that the locking hook 7 rotates upwards, finally the locking hook 7 is placed on the upper side of the locking block 10, the locking hook 7 moves to the lower side of a locking rod 6 along with the further movement of the stop lever 2 to the lifting hook 1, and then the locking hook 7 rotates downwards to hook the locking block 10 under the action of gravity, so that the self-locking of the lifting hook 1 and the stop lever is realized; after the hoisting is finished, the pull rope 13 is pulled downwards, the end of the lock rod 6 with the lock hook 7 tilts upwards and is separated from the lock block 10, and the stop lever 2 can be rotated outwards along the bottom in the hook rod 3 and the upper side of the guide rod 5.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
