[Prior art]
In the case of mobile missiles, they are mounted on a transport vehicle from the storage to the launch site and moved.However, even if they are subjected to vibrations during this transport, the missile must not fall from the transport vehicle. It is necessary to transport it firmly.
[0003]
Furthermore, it is desirable that the missile be quickly released from the fixed state at the destination by a simple operation.
[0004]
[0005]
Conventionally, as shown in FIG. 5, a missile 1 taken out of a storage is fastened and fixed to a mounting base 2 of a transporting vehicle by bolts 13.
[0006]
[Problems to be solved by the invention]
However, in the case where the bolts are tightened and stopped in this way, the tightening work depends on humans, and the work is complicated. Further, since the bolts may be forgotten to be tightened, the inspection is very complicated and requires huge labor costs.
[0007]
Further, in the case of the missile, it is necessary to quickly carry out the work of fixing and removing the load, but the work cannot be carried out quickly if the bolt is used in this way.
[0008]
In addition, in such a fixing device, it is necessary to firmly fix the device in a state where the vibration can be absorbed so that the device does not drop due to vibration or the like during transportation.
[0009]

[0011]
Still another object of the present invention is to provide an apparatus for fixing an object to be fixed, which can be securely fixed even if it receives an impact due to vibration or the like during conveyance after fixing.
[0012]
[Means for Solving the Problems]
In the present invention, the above-mentioned object, in a missile fixing device ,
A fixing member having an adapter portion that abuts against and fixes the missile at the tip portion, is swingably supported at a root portion opposite to the tip portion,
A crank member having a link connecting portion and a hydraulic cylinder connecting portion is swingably supported at a portion different from the link connecting portion and the hydraulic cylinder connecting portion,
A link connecting portion located between the distal end portion and the root portion of the fixing member, and a link connecting portion of the crank member are pin connected by a link member,
A hydraulic cylinder body of a hydraulic cylinder in which one direction movement of a rod is performed by a spring and another direction movement of the rod is performed by hydraulic pressure is swingably supported, and a hydraulic cylinder connecting portion between the rod of the hydraulic cylinder and the crank member. And the pin portion is connected to the adapter portion of the fixing member by the spring so as to restrain the missile ,
When the adapter portion comes into contact with the missile, the link connecting portion of the crank member is positioned above an imaginary line connecting the link connecting portion of the fixed member and the swing center of the crank member. A stopper member is provided to abut the crank member to limit the swing of the crank member ,
The missile fixing device is provided with a restraint detection switch for detecting that the adapter portion is in the restrained state and an unwinding switch for detecting the release state .
[0013]
That is, the present invention is a missile fixing device including a crank member, a link member, and a hydraulic cylinder, and a mechanism using a spring force when restraining and using a hydraulic cylinder operation when releasing. Can be performed extremely easily, can be fixed securely, and can be quickly and easily released. This mechanism is provided on the frame, and when the missile is restrained, the missile is restrained only by the spring force built into the hydraulic cylinder. Therefore, in the present invention, after the missile is fixed, the fixed state can be maintained without requiring any special power to maintain the state.
[0014]
Further, in the present invention, when the adapter portion of the fixed member abuts on the missile , the link connecting portion of the crank member connects the link connecting portion of the fixed member and the swing center of the crank member. A stopper member is provided so as to abut on the crank member and limit the swing of the crank member so as to be located above the line.
[0015]
That is, according to the present invention, when the missile is restrained , the position of the point B connecting the link member and the crank member is an imaginary line connecting the point A connecting the link member and the fixed member and the swing center point C of the crank member. By contacting the crank member with the stopper member in a more upward state, even if a high load acts on the adapter portion of the fixed member, the load is received by the stopper member from the fixed member via the link member and the crank member. Is not transmitted to the hydraulic cylinder. For this reason, even if it receives an impact due to vibration or the like during conveyance after the fixing, the fixing is surely continued.
[0016]
On the other hand, suppose that the position of the point B connecting the link member and the crank member is below the imaginary line connecting the point A connecting the link member and the fixed member and the swing center point C of the crank member. When fixed, when a large external load is applied to the fixing member from the missile to the missile restraining portion, the force acting on the hydraulic cylinder from the fixing member via the link member and the crank member opposes the spring force built into the hydraulic cylinder. The hydraulic cylinder shrinks and cannot withstand high loads.
[0017]
In the case of this embodiment of the present invention, it is preferable that the stopper member is constituted by a bolt or the like, and that the stop position can be adjusted by screwing the stopper member.
[0018]
Further, when the fixing device according to the present invention is operated, it is preferable that an adapter portion is attached to the fixing member via a disc spring so that the adapter portion reliably contacts the missile .
