Abstract

The utility model relates to a lifting hook capable of unhooking automatically. The lifting hook comprises a lifting hook body, a U-shaped shackle is mounted in the middle of the lifting hook body, two ends of the U-shaped shackle are connected with the middle of the lifting hook body via a pin and nuts, and the lifting hook body can rotate around the pin. The lifting hook is characterized in that a C-shaped hook body is arranged at one end of the lifting hook body, a hole is arranged at the other end of the lifting hook body, a permanent magnet is disposed in the hole, and a counter weight is disposed at the end, which is far away from the C-shaped hook body, of the lifting hook body. A plate which can be attached with the permanent magnet together is convexly arranged on one side, which is far away from the hook body, of the shackle. A supporting sleeve is sleeved outside the pin. The permanent magnet is fixed via a cylindrical pin. The lifting hook capable of unhooking automatically is simple in structure, is safe and reliable, and has the function of unhooking automatically.

Description

Suspension hook that can be automatically-unhooked

Technical field

The utility model relates to a kind of hanging device, especially a kind of suspension hook that can be automatically-unhooked.

Background technology

The supporting uses of hanging device such as general load hook and hoisting crane, driving, the place that is commonly used in each big harbour, harbour and loads and unloads handling goods such as service company.When handling goods, need manually to break off relations, if run in the high-altitude, local unloadings such as high temperature, high pressure, that just can not normal operation.In order to address this problem, must on load hook commonly used, carry out technological improvement and come to be used with general load hook, realize automatically-unhooked This move.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple and reasonable, high efficiency and safety performance good can be automatically-unhooked suspension hook.

The technical scheme that provides according to the utility model, described suspension hook that can be automatically-unhooked comprises the suspension hook body, at the middle part of suspension hook body the shackle of U type is installed, the both ends of described U type shackle are connected with the middle part of nut with the suspension hook body by bearing pin, and described suspension hook body can bearing pin be that rotate in the center of circle; Feature is: an end of described suspension hook body is a C type coupler body, and the other end is provided with the hole, and permanent magnet is set in the hole; Away from the end of C type coupler body one end clump weight is set at the suspension hook body.

On the side of described shackle, convex with the plate that can be attached together with permanent magnet away from coupler body.

Outside described bearing pin, be arranged with support set.

Described permanent magnet is fixed by straight pin.

Suspension hook structure letter that can be automatically-unhooked described in the utility model, safe and reliable, can play automatically-unhooked effect.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the lateral plan of Fig. 1.

Fig. 3 is the scheme drawing of the utility model under state of nature.

Fig. 4 is that suspension hook of the present utility model hangs up the scheme drawing under the rope state.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete accompanying drawing.

As Fig. 1～shown in Figure 4: can comprise shackle 1, plate 2, clump weight 3, permanent magnet 4, suspension hook body 5, support set 6, straight pin 7, nut 8, coupler body 9, bearing pin 10 etc. by automatically-unhooked suspension hook.

The utility model comprises suspension hook body 5, and an end of suspension hook body 5 is a C type coupler body 9, and the other end is provided with the hole, and permanent magnet 4 is set in the hole; Away from the end of C type coupler body 9 one ends clump weight 3 is set at suspension hook body 5; At the middle part of suspension hook body 5 U type shackle 1 is installed, the both ends of described U type shackle 1 are connected with the middle part of nut 8 with suspension hook body 5 by bearing pin 10, and described suspension hook body 5 can rotate for the center of circle by bearing pin 10;

On the side of shackle 1, convex with the plate 2 that can be attached together with permanent magnet 4 away from coupler body 9;

Outside bearing pin 10, be arranged with support set 6;

Described permanent magnet 4 is fixing by straight pin 7.

Principle of work of the present utility model: suspension hook body 5 is an equilibrium point with bearing pin 10, suspension hook body 5 is provided with the weight of the weight of clump weight 3 one ends greater than coupler body 9 one ends, under the effect of gravity and be not subjected under the state of nature of external force effect, the state of suspension hook body 5 such as the state of nature among Fig. 3, an end that is provided with clump weight 3 is sagging, Open Side Down for coupler body 9, can throw off the rope on the coupler body automatically; When hoisting heavy, after the workman hung over rope on the coupler body 9, permanent magnet 4 was inhaled under magnetic action with the plate 2 in the shackle 1 and is in the same place, and the center of gravity of suspension hook body 5 and the center of gravity of rope are accentrics at this moment, and the deadweight of rope is to separate permanent magnet 4 and plate 2; When slinging weight, weight of heavy is thoroughly separated permanent magnet 4 and plate 2, and separately the distance after is outside the magnetic field that has exceeded permanent magnet 4, and permanent magnet 4 and plate 2 can not lump together; After putting down weight, suspension hook body 1 reverts to free state again, and rope skids off from coupler body 9 automatically, has promptly just finished the automatically-unhooked process of suspension hook.
