Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, a single-hook structure for a crane according to a preferred embodiment of the present invention includes a hanging beam 1 and a hook body 2, the hanging beam 1 includes a connecting portion 3, a first lifting portion 4 and a second lifting portion 5, the hook body 2 is connected to the connecting portion 3, the first lifting portion 4 and the second lifting portion 5 are respectively and fixedly connected to two ends of the connecting portion 3, the first lifting portion 4 is provided with a first lifting rod 6, the second lifting portion 5 is provided with a second lifting rod 7, the first lifting rod 6 and the second lifting rod 7 are both used for connecting lifting straps, and the first lifting rod 6 and the second lifting rod 7 are symmetrically arranged with respect to the hook body 2. When hoisting, the first hoisting rod 6 and the second hoisting rod 7 are connected with the hanging strip, and the crane drives the hoisting beam 1 through the hanging strip, so that the hook body 2 is driven, and hoisting is realized. When the hook body 2 needs to be rotated, the distance which is not less than the length of the connecting part 3 is reserved between the hanging strip of the first hoisting part 4 and the hanging strip of the second hoisting part 5, so that the hanging strips can be prevented from being wound when the hook body 2 is rotated, and the operation of workers is facilitated. The connecting part 3 is detachably connected with the hook body 2. So set up, can be convenient for store and transport.
Wherein, first hoist and mount 6 level setting, the one end and the 4 fixed connection of first hoist and mount portion of first hoist and mount pole 6, the other end of first hoist and mount pole 6 is equipped with first fender 8. The second hoisting rod 7 is horizontally arranged, one end of the second hoisting rod 7 is fixedly connected with the second hoisting part 5, and the other end of the second hoisting rod 7 is provided with a second stopper 9. The first stopper 8 and the second stopper 9 can prevent the hanging strip from sliding down along the body of the first hoisting rod 6 or the second hoisting rod 7.
In addition, first hoist and mount portion 4 still is equipped with third hoist and mount pole 10, and second hoist and mount portion 5 still is equipped with fourth hoist and mount pole 11, and third hoist and mount pole 10 sets up with fourth hoist and mount pole 11 about coupler 2 symmetry. The third hoisting rod 10 and the fourth hoisting rod 11 are horizontally arranged, the third hoisting rod 10 and the first hoisting rod 6 are coaxially arranged, and the fourth hoisting rod 11 and the second hoisting rod 7 are coaxially arranged. Thus, the first hoisting rod 6 and the third hoisting rod 10 are symmetrical, and the second hoisting rod 7 and the fourth hoisting rod 11 are also symmetrical. Hanging belts are connected to the third hoisting rod 10 and the fourth hoisting rod 11, so that the tension on each hanging belt can be reduced, and the hoisting work is safer.
