Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a simple structure that allows one object to be tightly connected to another desired object and, when necessary, to easily and reliably disconnect the connection. This invention relates to an automatic disconnection device.

[Conventional technology]

Generally, it may be necessary to tightly connect one object to another desired object via a wire rope or the like, and then instantly break the connection and separate the two objects if necessary.

In such a case, for example, when a ship is launched, the launching slide, which is tied and fixed to the ship's hull with dozens of wire ropes, can be fixed by cutting off the wire ropes at the same time immediately after the ship is launched. , removal from the bottom of the ship, etc. 7 Normally, a ship is launched as shown in Figure 3. That is, the hull 1 rests on the launching platform 3 by its bottom 4, and the hull 1 and the launching slide 3 are connected to the launching slide 3 by the tens of water that is attached to the launching slide 3 via a shackle or the like. The wire rope 7 is fixed to a bracket provided on the deck 5 of the hull 1 by tightening it with several tens of disconnecting devices 6 fixed by turnbuckles or the like. The launch slide 3 slides on the launch fixed base 2 which is installed at an angle, and the launch is performed.

This disconnection device i! 6, a manual type as shown in FIG. 4 has conventionally been used. That is, at the other end of the main body link 8 on the rectangular plate, which has a fixing wire rope 15 for fixing the device itself at one end, there is a hook 9 for locking a connecting wire rope 14 for tightly connecting a desired object. It is rotatably attached to the main body link 8 in the longitudinal direction by a hook pin 11. On the other hand, main body link 8
A separation lever 10 is rotatably attached to the main body link 8 by a separation lever pin 12 on both sides of the central part of the , and a separation stop pin 13 fixed near the center of the separation lever 10 is attached to the tip of the hook 9. This prevents the hook 9 from rotating open due to the tensile force of the connecting wire rope 14.

[Problem that the invention seeks to solve]

Immediately after launching, the launching slide 3 is separated from the hull 1, but in the past, several dozen workers were required to do so.
This was done by simultaneously manually operating the disconnecting devices 6 that tighten each of the wire ropes 7 of several tens of water, and cutting off the wire ropes 7. In this case, each worker must use a sledgehammer to strike the disconnection lever 10 of the disconnection device 6 at the same time to release the restraint on the hook 9, which requires great effort and timing. Ta. If a deviation occurs in this timing, a large load may be applied to the disconnection device 6 that is delayed in operation, causing it to break, creating a risk of injury to the operator or damage to other items. Ta.

[Means for solving problems]

As a result of intensive research in order to solve these problems, the present inventors found that by using the gas-operated retracting pin of the present invention, these conventional problems could be solved at once, and the present invention was developed. It was completed.

That is, the present invention provides an automatic disconnection device that has a simple structure, is safe and reliable, and can operate a large number of devices at the same time.

Next, an example of an embodiment of the present invention will be described with reference to the drawings.

1 and 2 are perspective views showing the automatic disconnection device of the present invention before and after operation.

In these figures, 1 the automatic cutting device of the present invention is shown in the 4th section.
The conventional manual disconnection device shown in the figure and the main body link 8,
Hook 9. Hook pin 11, connecting wire rope 14.
The fixing wire rope 15 is the same.

As shown in FIG. 1, the tip of this hook 9 is connected to a pair of crosspiece lever receivers 17 fixed at right angles to the center of both sides of the main body link 8 before operation. The beam lever 16 held by the lever 18 prevents its rotation and locks the connecting wire rope 14. However, after the operation, as shown in FIG. 2, the rotation of the hook 9 is no longer inhibited by the crosspiece lever 16, and the hook 9 rotates around the hook pin 110 to open.

The connecting wire rope 14 comes off the hook 9, and the desired object connected to the other end of the connecting wire rope 14 is separated together with the connecting wire rope 14.

One end of the crosspiece lever 16 is rotatably attached to the tip of the crosspiece lever receiver 17 by a crosspiece lever pin 19, and the other end of the crosspiece lever 16 is attached to the tip of the other pair of crosspiece lever receivers 18 before operation. A gas-operated retractable pin 20 attached to the section engages with the tip of the crosspiece lever receiver 18 to prevent the hook 9 from rotating. Note that a pair of electric conductors 21 for operating the gas-operated retracting pin 2o are attached to the gas-operated retracting pin 2o.

Further, FIGS. 5 and 6 show a gas-operated retraction pin 20.
It is sectional drawing which shows the state before and after operation|movement of.

In these figures, 27 is a cylindrical piston pin with a larger outer diameter near the center, and has a cavity a that extends from the rear end to a point slightly farther toward the tip than the larger outer diameter part. . A gas generator 26 is fixed to the rear end of the cavity a with a screw cap 33, and the distal end thereof has a plurality of ventilation holes C communicating the cavity a with the outside world.

The piston pin 27 is slidably fitted into a cylinder 28 which has a step near the center of the inner wall so that the tip of the piston pin 27 enters a small part of the inner diameter of the cylinder 28. A space is formed between the part where the outer diameter of the piston pin 27 is increased and the step of the inner wall of the cylinder 28, and this space is formed by a plurality of ventilation holes C provided in the piston pin 27. It communicates with cavity a. Further, the end surface of the large inner diameter portion of the cylinder 28 is fixed by a locking nut 29 so that it will not fall off from the cylinder 28 when the screws 1 to 27 are operated.

On the other hand, the gas generator 26 has a screw cap 33 for fixing it in the cavity a of the piston pin 27. A pair of electric conductors 21 pass through the screw cap 33, and the electric wires 21 are connected between both ends of the inner side of the screw cap 33, and heat is generated when electricity is applied! 22. An ignition agent 23 applied around the ignition agent 23 and ignited by the heat generated by the exothermic wire 22; a gas generating agent 24 that burns and generates gas upon ignition;
The gas generating agent container 25 is fixed to a screw cap 33.

Further, on the outer periphery of the piston pin 27, when the piston pin 27 is operated, there is a circle 30, 31 for maintaining airtightness with the inner wall of the cylinder 28, and when the piston pin 27 is operated, the part where the outer diameter of the piston pin 27 is increased is attached to a locking nut. A cushion ring 32 is provided for absorbing the shock that collides with 29. The diameter of the screw cap 33 is larger than the diameter of the piston pin 27.

This prevents the piston pin 27 from fitting into the cylinder 28 excessively.

The gas-operated retracting pin 20 configured as described above is attached to the tip of the crosspiece lever receiver 18 by screwing the threaded portion on the outside of the tip of the cylinder 28 into a screw hole provided in the crosspiece lever receiver 18.

[Effect]

To perform disconnection using the automatic disconnection device of the present invention, first, an electric current is passed through the electric conductor 21 to cause the heating wire 22 to generate heat and ignite the ignition agent 23, thereby causing the gas generating agent 24 to ignite.
By burning the gas, the gas generating agent container 25 is destroyed by the pressure of the generated gas, and the gas flows into the cavity a.
filled within.

Further, the filled gas flows into the space through a plurality of vent holes C provided in the piston pin 27. As a result, the volume of the space is expanded, so the piston pin 27 slides in the direction of the locking nut 29, moves until the cushion ring 32 hits the locking nut 29, and the tip of the piston pin 27 is attached to the cylinder 28. Pull inward.

By this, the crosspiece lever 16 by the crosspiece lever receiver 18
is disengaged, and by the tip of the hook 9 which is about to rotate due to the tensile force of the connecting wire rope 14, the crosspiece lever 16 is flipped up, the hook 9 rotates to open, and the connecting wire rope 14 is rotated. Off hook 9,
The connection with the desired object is instantly severed.

〔Effect of the invention〕

If the automatic disconnection device of the present invention is used, when disconnecting the launching slide, it is only necessary to energize the electric conductor manually or automatically, and it does not require the great effort and attention of many workers as in the past. Labor-saving work in separating the launching slide.

It is possible to achieve unmanned operation, and it is also possible to prevent injury to workers and damage to articles due to deviations in the timing of separation, unlike in the past.

In order to operate the gas-operated retracting pin, other than the gas generator of the present invention, for example, an electromagnetic force or an electric motor can be used, but especially when used on the hull during launching, it requires less electric power. The automatic disconnection device using the gas generator of the present invention is excellent because it operates quickly and the time required for retracting the piston pin is short.

Further, the gas generator of the present invention can be reused by replacing only the exothermic wire, the igniter, the gas generating agent, and the gas generating agent container after one operation, which is economically advantageous.
