Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 1 and 2, for the utility model discloses a lifting hook, including connecting block 1 and lifting hook body 2, the one end at connecting block 1 is fixed to the one end of lifting hook body 2. Wear to be equipped with in the connecting block 1 and shelter from pole 3, the week side that shelters from pole 3 is equipped with the screw thread, shelters from the level of pole 3 and 1 screw thread of connecting block are hard, shelters from the opening part that pole 3 is used for sheltering from lifting hook body 2. A cavity is arranged in the connecting block 1, and a driving component for driving the blocking rod 3 to rotate so as to enable the blocking rod 3 to extend out of or retract into the connecting block 1 is arranged in the cavity. When the rope was hung to the cover, drive through drive assembly and shelter from the inside of 3 indentation connecting blocks 1 of pole to open the opening of lifting hook body 2 completely, made things convenient for the rope cover to hang in lifting hook body 2. The rope cover is hung on lifting hook body 2 back, drives through drive assembly and shelters from pole 3 and stretch out connecting block 1 to made things convenient for on lifting hook body 2 with the rope restriction, reduced the possibility that the rope breaks away from lifting hook body 2.
Referring to fig. 2 and 3, the driving assembly includes a worm wheel 4 and a worm 5. Worm wheel 4 rotates and installs on the lateral wall of cavity in connecting block 1, and worm 5 rotates and installs on connecting block 1, and the axis of worm 5 sets up with the plane at 2 places of lifting hook bodies perpendicularly, and worm 5 and worm wheel 4 mesh, and the one end of worm 5 stretches out connecting block 1. A knob 6 is coaxially fixed on one side of the worm 5 penetrating through the connecting block 1. The shielding rod 3 is coaxially sleeved on the worm wheel 4, and a limiting part for limiting the rotation of the shielding rod 3 relative to the worm wheel 4 is arranged between the worm wheel 4 and the shielding rod 3. When the shielding rod 3 needs to be driven to stretch, the worm 5 is rotated, and the worm 5 is meshed with the worm wheel 4, so that the worm wheel 4 rotates along with the rotation of the worm 5. Under the effect of locating part, sheltering from pole 3 and rotating along with worm wheel 4 in the lump, sheltering from 3 rotation in-process of pole and made things convenient for sheltering from pole 3 and stretched out or indentation connecting block 1 to this opening of opening or closing lifting hook body 2 has been made things convenient for.
Referring to fig. 2 and 3, the blocking rod 3 is provided with a limiting groove 8 consistent with the length direction thereof, and the limiting part is a limiting block 7. The limiting block 7 is fixed on the inner peripheral side of the worm wheel 4, and the limiting block 7 is arranged in the limiting groove 8 in a sliding mode. The limiting block 7 is arranged in the limiting groove 8 in a sliding mode, so that the shielding rod 3 is limited and is not prone to relative rotation with the worm wheel 4, and the shielding rod 3 is driven to rotate conveniently. Along with sheltering from the rotation of pole 3, shelter from pole 3 and slide along its axis direction to worm wheel 4 earlier gradually, stopper 7 slides in spacing groove 8 this moment to made things convenient for the drive to shelter from pole 3 and stretch out or indentation connecting block 1, with this convenient opening that shelters from pole 3 and shelter from or open lifting hook body 2.
Referring to fig. 2 and 3, in order to improve the strength of the blocking rod 3, the hook body 2 is provided with an adaptation hole 9 through which the blocking rod 3 passes. When the shielding rod 3 extends out of the connecting block 1 to shield the opening of the hook body 2, one end of the shielding rod 3 is inserted into the adapting hole 9, so that the two ends of the shielding rod 3 are supported, and the bearing capacity of the shielding rod 3 is improved.
In order to reduce the possibility of the hook body 2 being rusted, the surface of the hook body 2 is provided with a rust-proof coating. The antirust coating is antirust paint.
The implementation principle of the embodiment is as follows: when the rope cover was hung on lifting hook body 2, earlier drive through drive assembly and shelter from in 3 indentation connecting blocks 1 of pole, the opening of lifting hook body 2 was in open state this moment, had made things convenient for the rope cover to hang in the inside of lifting hook body 2. After the rope is hung, the blocking rod 3 is driven by the driving assembly to extend out of the connecting block 1, one end of the blocking rod 3 extending out is inserted into the adapting hole 9, the blocking rod 3 blocks the opening of the lifting hook body 2, and therefore the rope is not prone to being separated from the lifting hook body 2. Wherein will shelter from in 3 indentation connecting blocks 1 of pole, make things convenient for the cover of rope to hang, through will shelter from pole 3 and stretch out connecting block 1, conveniently shelter from the opening of lifting hook body 2, reduced the possibility that the rope breaks away from lifting hook body 2.
Example two:
referring to fig. 4, a tightener for long-distance power transmission comprises a hook 11 as described in the first embodiment, and further comprises a tightener body 10, wherein the hook 11 is arranged at the connecting position of the tightener body 10 and a rope.
The tightener body 10 has the advantages that the lifting hook 11 is used, so that the rope can enter the lifting hook body 2 conveniently, the opening of the lifting hook body 2 is shielded conveniently, and the possibility that the rope is separated from the lifting hook body 2 is reduced.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
