In addition, until now, the fixation device for the heavy pipe of the launching pipe developed in Korea has a low reliability in releasing the heavy object by using two or more explosion bolts or requiring a lot of mechanical operation.

Accordingly, there is a demand for a device that can prevent movement of a heavy object by using a simple kinematic operation, and can reliably unlock and confirm a heavy object.

In addition, although there are clamp type heavy object fixing devices outside the country, they are different in shape and do not have a heavy object unlocking confirmation device.

Korea Patent No. 20-0183732

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a method of fixing a structure of a launching tube and a heavy object during transportation and operation of a heavy object, Clamping type heavy object fixing device for a launching lug capable of releasing the fixing of a heavy object by applying an electric signal to the explosive bolt and confirming the unlocking of the heavy object.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a hinge clamp type heavy object fixing device for a launching tube, comprising: a cylindrical structure flanged to a discharge tube; a heavy object to be closely fitted to the inner peripheral surface of the structure; And the clamping portion formed on the detachable portion of the clamp is coupled or separated to selectively support the structure and the heavy object.

Further, an annular protrusion protruding radially outward is provided on the outer peripheral surface of the heavy object, and the heavy object is seated on the upper edge of the structure by the annular protrusion.

In addition, a receiving groove for receiving and fixing the annular projection is formed on the inner side surface of the fastening portion.

Further, the fastening portion is coupled by the explosion bolt, and the explosion bolt is broken and the fastening portion is separated.

In addition, a PCB including a conduction circuit is provided, and the PCB is installed in a state of being penetrated by the explosion bolt, so that the PCB is short-circuited at the same time as the explosion bolt is broken, .

Further, a plate spring is installed such that one end thereof is in close contact with the outer circumferential surface of the structure, and the other end is provided with a leaf spring for elastically supporting a part of the clamp in a radial direction of the structure.

And a fixing pin elastically supported between the hinges of the clamp by a coil spring in a state of being in contact with a lower surface of the clamp, and protruding so as to be fitted between the hinges when the clamp is opened.

As described above, according to the hinge clamp type heavy object fixing apparatus for a launching tube according to the present invention, a hinge type clamp, which includes an explosion bolt attached to a cylindrical structure behind a cast tube, So that it is possible to securely fix the weight of the heavy object and release the reliable restraint of the heavy object at the time of launching the heavy object.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a hinge clamp type heavy object fixing apparatus for a launch tube according to an embodiment of the present invention. FIG. 2 is a perspective view of a hinge clamp type heavy object fixing apparatus for a launch tube according to an embodiment of the present invention. Fig.

1 and 2, a hinge clamp type heavy object fixing apparatus for a launching tube according to an embodiment of the present invention includes a cylindrical structure 100, a heavy object 300, and a clamp 200, which are flanged to the rear of a launch tube, .

The structure 100 is coupled to the rear of the launch tube (not shown) by a flange 110 formed radially outwardly at the lower end.

One end of the heavy object 300 is protruded while the heavy object 300 is loaded in the structure 100 and the protruded portion is fixed to the structure 100 by the clamp 200. At this time, an annular protrusion 301 protruding radially outward is formed on the outer circumferential surface of the heavy object 300, and the heavy object 300 is fixed to the upper edge of the structure 100 by the annular protrusion 301 .

The clamp 200 is formed so as to be opened or closed by being rotated toward the opposite sides with respect to the hinge 202. That is, when the hinge-type clamp 200 is broken, the inner circumferential surface thereof presses the outer circumferential surface of the heavy object 300 and the outer circumferential surface of the structure 100 together.

At this time, the clamp 200 has a coupling part 210 that is rotated to the opposite side so that the ends thereof are coupled to or separated from each other. The receiving groove 211 is formed on the inner side surface of the coupling part 210 so that the annular projection 301 can be received and fixedly supported. That is, the annular protrusion 301 is engaged with the upper and lower latching protrusions 211a and 211b of the receiving groove 211.

The hinge-type clamp 200 can be screwed using an explosion bolt 212, and a PCB 214 penetrated by the explosion bolt 212 is provided.

Since the explosive bolt 212 for fixing the clamp 200 does not support the load in the longitudinal direction of the heavy object 300, the load supporting capacity of the explosive bolt 212 is designed to be high even if the heavy object to be fixed is heavy. This has the advantage of not being used.

Fig. 2 shows a configuration in which the hinge-type clamp 200 is operated by the explosion bolt 212 to release the fixing of the heavy object. A detonator is built in the detonation bolt 212 to detonate the detonator when an explosion signal is applied from the outside. That is, in the course of the rotation of the clamp 200 in the direction in which the clamp 200 is widened around the hinge 202 by the breaking force of the explosion bolt 212, the fixing of the heavy object 300 is released, 214 are broken. With the breakage of the PCB 214, the conducting circuit is short-circuited to generate a fixed release signal between the heavy object and the structure.

FIG. 3 is a longitudinal sectional view showing a state where a connecting portion applied to a hinge clamp type heavy object fixing apparatus for a launching tube according to an embodiment of the present invention is engaged. FIG. 4 is a cross- And FIG. 8 is a longitudinal sectional view showing a state in which a connection part applied to the fixing device is separated. As shown in the drawing, FIG. 3 shows a casting tube structure in which the hinge type clamp 200 is fixed by the explosion bolt 212, FIG. 4 shows a structure of the hinge type after the explosion bolt 212 is broken by an electrical signal, The PCB 214 is broken due to the rotation of the clamp 200. When the PCB 214 is short-circuited by the breakage of the PCB 214, it is possible to accurately grasp whether the heavy object 300 is unlocked or not when the controller 214 is applied to a control unit (not shown)

In addition, in order to reliably release the heavy object, the clamping force of the explosive bolt 212 is used together with the compressed leaf spring 204 to smooth the rotation of the clamp 200 around the hinge 202, And a fixing pin 203 for preventing the base member 200 from colliding with the structure and bouncing again. The fixing pin 203 is protruded by the coil spring 203a compressed at the center of the hinge 202 and inserted between the hinges 202 by the expansion of the clamp 200, To prevent rotational movement in the direction.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
