Description

Non-slip Sea Hook {C-Hook to prevent the steel coil from sliding}

The present invention relates to a non-slip sea hook, which is described in detail. The coil slides to an end of a sea hook which is coupled to a hook of a overhead crane carrying a rolling coil in a rolling mill and pushed into a central portion of a rolled coil. It relates to an anti-slip sea hook provided with a non-slip stop wave so as not to fall off.

Generally, overhead cranes are used to transport or load heavy materials, and cranes are used essentially in places where heavy materials are transported due to the characteristics of work, such as steel mills or cast steel failures.

The method of transporting heavy goods using a crane is a method of moving a crane by hooking a rope to a hook of a crane after fixing the goods to be transported with a rope. It takes time and there is a risk of safety accidents due to disconnection or loosening of the rope. Therefore, it is necessary to manufacture a transport box to transport the heavy goods in the box, or to form a hook that can be hooked to the heavy weight itself. It is used.

However, the continuous transport of the same weight is provided with a hook that is coupled to the crane hook and the lower portion is used to transport the heavy weight by using a device for holding a specific weight, which is better in terms of safety and performance than the above-described method. There is an advantage to see the effect.

Therefore, even in rolling mills that require the loading and loading of steel coils, they are coupled to the crane hook when transporting the steel coils, and the lower part is used to insert a coil into the hollow part of the coiled steel coil and carry the coil to carry it. There is it and is called C-HOOK.

Looking at the alternative configuration of the sea hook, as shown in Figure 1 hook hook 20 is inserted into the hook hook of the overhead crane is formed on the upper side and C-shaped hook body 10 is formed on the lower side C shape The hollow portion of the forced coil is fitted to the lower working portion 40 of the structure is lifted up.

In addition, the upper portion of the body is provided with a head that serves as a counterweight to maintain the balance with the weight when lifting the weight to achieve the sea hook equilibrium.

However, when the steel coil is transported or loaded using the above-described sea hook, if the steel coil is not wound properly, that is, it is not wound properly, it is difficult to push the coil into the sea hook and the worker pushes the hand or moves the crane. In addition, there is an inconvenience of pushing the sea hook and the edge of the steel coil is damaged by friction or collision.

In addition, if the equilibrium of the sea hook is not appropriate while the steel coil is being transported by the sea hook or the rolling oil on the steel plate during the rolling operation, the coil slips on the sea hook and an accident occurs from the sea hook. Even when the equilibrium is not matched, when the steel sheet coil is seated on the ground, the edge portion of the coil is first attached to the ground, thereby causing the edge portion to be broken.

Therefore, the technical problem to be solved in this paper is to safely push the steel plate coil into the sea hook body when transporting the steel plate coil using the sea hook to solve the above-mentioned problems, The present invention provides a shape of a sea hook that does not slip away from the sea hook.

The lower surface has a fixing protrusion which can be inserted into the hole by pressing the elastic body is formed in the same number as the hole, and both sides of the fixing protrusion is formed with protrusions are inserted into the incision groove and elastically coupled with the lining ,

It is coupled between the two protruding end portions of the working portion is coupled by a pin so that the front is provided with an inclined contact surface in sliding contact with the protrusion provided on the lining and the inclined contact surface is provided with a protruding contact portion in contact with the bottom surface of the lining It is composed of waves.

Hereinafter, described in detail with reference to the drawings shown.

As described above, the central end of the directional end is cut, and both side ends 45 are protruded, and pinholes 41 are formed between the protruding both end portions, and the pin 70 is inserted in the middle of the upper surface, and the elastic body is accommodated at the bottom end. The working part 40 having the cutout groove 42 having the hole 43 formed therein, and the two protrusions 51 are formed in the bottom surface thereof in parallel with the cutting groove 42 formed in the working part. And it is inserted between the lining 50 is provided with the fixing projection 52 is inserted into the hole 43 provided in the working part 40 and the working part pin hole 41 is coupled to be rotated by the pin 70 The pinholes 63 are provided at both sides, and the front surface of the inclined contact surface 61 in sliding contact with the end of the protruding portion 51 provided on the lining 50 and the inclined contact surface 61 is horizontally projected to the lining protrusion 51. Stop 60 provided with contact portion 62 in contact with the bottom surface between It is composed of

Referring to the operation of the present invention by the prepared drawings as follows.

In the case of conveying the steel sheet coil using the anti-slip sea hook provided with the present invention, when the steel sheet coil is inserted into the working part 40 such that the edge portion of the steel sheet coil reaches the lining 50, the coil is lifted using the crane. When raised, the lining 40 is moved to the cutting groove 42 provided in the bottom surface of the work under pressure by the coil load.

By moving the lining 50, the protrusion 51 provided on the lower surface of the lining is also moved downward, and at this time, the inclined contact surface 61 provided on the front of the stopper 60, which is pivotally coupled to the end of the working part 40, Riding and pressing the inclined contact surface 61 and the stop wave 60 received a force on the inclined contact surface 61 is gradually rotated around the pin 70 by the inclination of the inclined contact surface.

The stopper, which is slowly rotated by the above-described action, rotates about 15 ° and pushes the coil caught by the work end inward. If the above-described action continues, the lining 50 causes the bottom surface between the protrusions 51 to be inclined contact surface ( The bottom surface of the lining 50 presses the contact portion 62 vertically.

The contact 62, which receives the vertical force from the lining 50, is rotated about the pin 70 and this movement is continued until the contact 62 is rotated 90 °.

Therefore, the opposite side of the contact portion also rotates by 90 °, so that the stopper 60 standing vertically appears at the end of the sea hook.

On the contrary, when the steel sheet coil is seated on the ground, the pressing force of the lining 50 disappears and at the same time, the lining 50 is moved upward by the restoring force of the receiving surface elastic body 44 in the cut hole bottom hole 43 of the work part. The stopper 60 rotates by its own weight and returns to its original position.

The returned stopper 60 is maintained in the return state by the contact between the inclined contact surface 61 and the protrusion 51.

As an effect of the present invention, even when the coil is forcibly inserted into the sea hook due to a poor winding state of the steel sheet coil or other reasons, it can be easily performed by using a stopper. The coil can be safely transported by preventing the coil from escaping from the sea hook so that it is possible to prevent damage to the edge of the coil as well as a safety accident that occurred during the coil transportation.
