Abstract
The utility model relates to a self-releasing lifting hook, which comprises a hook body, a lifting ring arranged on the hook body and provided with a penetrating sling, and a stay cable arranged at the other end of the hook body and fixedly connected with the hook body. The self-releasing lifting hook is a hoisting tool used in operations as follows: lifting weights to a certain height and leadingthe weights to fall free. The self-releasing lifting hook can be widely applied to industrial trade and building trade, such as foundation consolidating operation, article crushing (smashing) operation, and the like; and the operations all need strong impacting force, and the strong impacting force can be formed by the free falling of objects. The self-releasing lifting hook adopts the lever principle and has the characteristics of simple construction, convenient and practical operation, low manufacturing cost, etc.
Description
Technical field
The utility model relates to a kind of Automatic unhooking hook.
Background technology
At present, in the operation of lay a good foundation, break into pieces in the operation of (smashing) article and all need very strong impulsive force, this impulsive force can lean on the free fall object to form.The compacting percussion mechanism complex structure that is adopted, complex operation, be difficult for grasping and existing certain danger.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple structure, easy to operate practicality, can be widely used in the Automatic unhooking hook in industry, the building industry.
The utility model adopts following technical scheme:
The utility model by coupler body, be arranged on the suspension ring that are installed with hoist cable on the coupler body and be arranged on the drag-line that the other end of coupler body is captiveed joint with coupler body.
The other end at coupler body is provided with the lacing grommet that is connected with drag-line.
Good effect of the present utility model is as follows: the utility model is a kind of lifting device that weight uses to the operation of certain altitude by the weight free fall of slinging, the utility model can be widely used in industry, the building industry, for example: the operation of lay a good foundation, break the operation of (smashing) article etc. into pieces, all need very strong impulsive force, this impulsive force can lean on the free fall object to form.The utility model utilizes lever principle, has characteristics such as simple structure, easy to operate practicality, cost of manufacture be low.
Description of drawings
Accompanying drawing is the utility model structural representation.
In the accompanying drawings: 1 coupler body, 2 hoist cables, 3 suspension ring, 4 drag-lines, 5 lacing grommets.
The specific embodiment
As shown in drawings, the utility model by coupler body 1, be arranged on the suspension ring that are installed with hoist cable 23 on the coupler body 1 and be arranged on the drag-line 4 that the other end of coupler body 1 is captiveed joint with coupler body 1.The other end at coupler body 1 is provided with the lacing grommet 5 that is connected with drag-line 4.
3 effects of the utility model suspension ring are to be convenient to hoisting crane to hook the utility model from breaking off relations.Coupler body 1 effect is to hook weight.Lacing grommet 5 effect is that to be convenient to be drag-line 4.The effect of drag-line 4 is control weight height of lift, and oneself breaks off relations to reach automatically-unhooked purpose with the utility model to apply pulling force.After regulating the length of drag-line 4, the other end of drag-line 4 can lie in bearing, but also manual operation.When weight-lifting equipment the utility model autospasy hook block ring of slinging, the utility model is after the suspension hook that breaks off relations hooks weight, utilize lever principle, with suspension ring 3 is fulcrum, the one end arm of force of drag-line 4 is long, the coupler body 1 one end arm of forces are short, and drag-line 4 one ends just can make the direction rotation of whole Automatic unhooking hook towards drag-line 4 tractions with very little power like this, thereby make whole Automatic unhooking hook tilt to reach from breaking off relations purpose.Regulate the length of drag-line 4 and can control height of lift.The utility model coupler body 1, suspension ring 3 and lacing grommet 5 etc. are made of the Q345 steel, and drag-line 4 and hoist cable 2 usefulness steel ropes are made.The concrete size at each position of the utility model Automatic unhooking hook can be according to the weight of heavy design of being sling.
Claims (2)
1, a kind of Automatic unhooking hook, it is characterized in that its by coupler body (1), be arranged on the suspension ring that are installed with hoist cable (2) (3) on the coupler body (1) and be arranged on the drag-line (4) that the other end of coupler body (1) is captiveed joint with coupler body (1).
2, a kind of Automatic unhooking hook according to claim 1 is characterized in that being provided with the lacing grommet (5) that is connected with drag-line (4) at the other end of coupler body (1).
