Abstract

The invention relates to a self-releasing hook which comprises a hook body, wherein the middle part of the hook body is provided with a U-shaped shackle; both ends of the U-shaped shackle are connected with the middle part of the hook body through an axis pin and a nut; and the hook body can rotate by using the axis pin as the center of circle. The invention is characterized in that one end of the hook body is a C-shaped hook body, the other end of the hook body is provided with a hole, and a permanent magnet is arranged in the hole; and the end of the hook body, which is far from one end of the C-shaped hook body, is provided with a clump weight. One side of the shackle, which is far from the hook body, is convexly provided with a board which can be adsorbed with the permanent magnet; a support sleeve is sheathed outside the axis pin; and the permanent magnet is fixed by a cylindrical pin. The self-releasing hook has the advantages of simple structure, safety and reliability, and can perform the function of self-releasing.

Description

Suspension hook that can be automatically-unhooked
Technical field
The present invention 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 objective of the invention 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.
According to technical scheme provided by the invention, 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 of the present invention, safe and reliable, can play automatically-unhooked effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the lateral plan of Fig. 1.
Fig. 3 is the scheme drawing of the present invention under state of nature.
Fig. 4 is that suspension hook of the present invention hangs up the scheme drawing under the rope state.
The specific embodiment
The invention will be further described 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 present invention includes suspension hook body 5, 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 invention: 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.
