Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading device for loading a projectile such as a minefield treatment bullet into a launcher.

2. Description of the Related Art A conventional method and its problems are shown in FIG. 8 for loading a minefield treatment bullet (rocket) for launching a mine, such as a landmine, into a launcher. (For example, see Japanese Patent Laid-Open No. 59-74500). That is, 90 is a minefield treatment bullet (hereinafter simply referred to as a treatment bullet) 91
A carrier vehicle for carrying the vehicle 92 is a launcher mounted on the tracked vehicle 93. The worker M rides on the launcher 92 and opens the upper lid 94 of the launcher 92, while the storage box 95 of the carrier vehicle 90 is provided. Then, the treated bullet 91 is lifted by the crane 96, and the treated bullet 91 is loaded into the launcher 92 with the help of the operator M. Then, when the loading of the treatment bullets 91 is completed, the upper lid 94 is closed, the launcher 92 is tilted and displaced to a predetermined firing angle posture, and then the treatment bullets 91 are fired by a conventional method.

However, in the conventional loading work, the worker M must ride on the launcher 92 whose scaffolding conditions are not sufficient to open / close the upper lid 94 and guide the processing bullets 91, which is so-called high-altitude work. It is not preferable in terms of safety measures, and especially when the terrain of the loading place is inclined, the above-mentioned loading work becomes difficult.

Further, instead of the above-described loading work from the top of the launcher, for example, as disclosed in Japanese Utility Model Publication No. 62-172997, the loading mechanism is arranged on the extension line of the turret of the tank, and the center of the gun is placed. There is a rammer part that reciprocates in the direction so that the shell is loaded from the breech part of the gun.

In this method, although it is relieved of high-altitude work at the time of loading, it simply pushes the shell into the gun by the lammer portion that contacts the bottom of the shell. Difficult to take out.

In other words, in the case of a large projectile such as the treatment bullet 91 described above, when the treatment bullet 91 is once loaded into the launcher 92 and the firing is canceled and the movement is made to another launch point, It is necessary to take out the treated bullet 91 from the launcher 92 each time, and it is an important factor in the flexibility of the equipment that not only the loading of the treated bullet as a projectile but also the taking out thereof can be performed smoothly. Therefore, the loading device described in Japanese Utility Model Laid-Open No. 62-172997 cannot meet the above-mentioned demand for equipment flexibility.

The present invention has been made in view of the above problems,
An object of the invention is to obtain a loading device which does not particularly require work at a high place and can smoothly carry out not only loading of a projectile into a launcher but also removal thereof.

Means for Solving the Problems The present invention is a device for loading a projectile such as a minefield treatment bullet in a projectile storage unit of a launcher while moving the minefield treatment ammunition in the axial direction thereof, and is connected to one end of the launcher. And a loading rail part on which the flying body is mounted, and reciprocally mounted on the loading rail part and engaged with a part of the flying body to load the flying body into the flying body storage section and from the flying body storage section. An engaging member for taking out the flying body, and a drive mechanism for reciprocating the engaging member in the axial direction of the flying body along the loading rail portion,
At least a switching operation mechanism is provided for selectively switching between the engaged state and the disengaged state of the projectile and the engaging member when the projectile is taken out from the projectile storage unit.

Operation According to this structure, by connecting the loading rail portion to, for example, the front end of the launcher, the loading rail portion and the launcher rail on the launcher side are aligned. In this state, by moving the engaging member that engages with a part of the flying object forward or backward, it is possible to load the flying object into the flying object storage portion or pull out the flying object from the flying object storage portion. Become.

Embodiment FIG. 2 shows an embodiment of the present invention, in which 1 is a loading device,
2 is a vehicle carrier equipped with a crane 3; 4 is a loading vehicle 5
Is a launcher installed in. The launcher 4 has a structure in which it can be tilted and displaced to a predetermined launch angle posture about a hinge pin 6 by the action of an actuator (not shown), and at the same time, its front surface 4b is opened and closed by a hinge-type lid (not shown). Has become.

The loading device 1 is configured with a loading rail portion 7 as a center, and a processing bullet 8 as a flying body is positioned and fixed on the loading rail portion 7 and is loaded and transported on the transport vehicle 2. Then, as will be described later, the processing bullets 8 are lifted together with the loading rail section 7 by the crane 3 from the loading platform of the transport vehicle 2, and the loading rail section 7 is connected to the front end of the launcher 4 to load and unload the processing bullets 8. Be seen.

A foldable leg portion 9 is attached to the loading rail portion 7, and as shown in FIG.
After being lifted up by, the leg 9 is landed on a part of the tracked vehicle 5, whereby the stable posture of the loading device 1 is maintained.

Is wrapped around. And this crawler chain
16 includes a launcher slipper 17 on the side of the treated bullet 8 as described later.
A hook member 18 as an engaging member that engages with is attached.

A pair of chain sprockets 19, 20 are attached to a position below the crawler beam 13 in the loading rail portion 7, and these lower chain sprockets 19, 20 are attached.
A crawler chain 21 on the lower side is also wound in parallel with the crawler chain 16 on the crawler beam 13 side.
And the crawler beam 13 and the lower side crawler chain
21 are connected to each other via a connecting rod 22.

Further, the lower side crawler chain 21 meshes with a chain sprocket 25 that is provided coaxially with the output gear 24 of the transmission gear unit 23, and the transmission gear unit 23 is rotated by rotating the operation handle 26 of the transmission gear unit 23. The crawler chain 21 is driven to travel through the internal gear train.

Therefore, when the lower side crawler chain 21 is run by rotating the operating handle 26, the crawler chain 21
The crawler beam 13 connected to the crawler beam 13 linearly reciprocates, and according to the displacement of the crawler beam 13, the crawler chain 16 on the upper side travels by a stroke that is exactly twice the stroke of the crawler beam 13. That is,
The crawler beam 13, the crawler chains 16 and 21, the speed change gear unit 23, and the like constitute a drive mechanism 27 for reciprocally driving the hook member 18. In this case, a motor can be used instead of the operation handle 26 of the transmission gear unit 23.

Reference numeral 28 denotes a lock mechanism for positioning and fixing the processing bullet 8 on the loading rail portion 7 by sandwiching another launcher slipper 29 of the processing bullet 8 from the front and rear thereof. The locking mechanism 28 is provided with a link 30, By rocking and displacing 31, the lock and unlock states can be switched.

3, 4 and 5 show the above crawler chain.
FIG. 3 is a diagram showing details of the hook member 18 as an engaging member attached to the 16 (however, in order to avoid complication of the drawing,
The crawler chain 16 is not shown in FIGS. 3, 4 and 5), and the hook member 18 is a front hook plate whose tip portion 32a is located in front of the launcher slipper 17 as shown in FIGS. 4 and 5. 32, a rear hook plate whose tip 33a is also located on the rear side of the launcher slipper 17
The hook plates 32 and 33 are swingable around the hinge pins 34 and 35, respectively.
A torsion coil spring 36 is provided between the hook plates 32 and 33, and the hook plates 32 and 33 are
A rotational biasing force in an upward direction is applied to each of them.

A guide plate 38 that is vertically swingable around a hinge portion 37 is attached to the side surface of the crawler beam 13, and a cam lever 39 integral with the rear hook plate 33 is engaged with the tip of the guide plate 38. . On the other hand, a pair of front and rear link levers 41 and 42 are rotatably provided on the side surface of the beam guide 11 of the loading rail portion 7 as shown in FIGS. The parts and the lower ends are connected to each other by parallel bars 43 and 44. And the upper bar 43
Engage with the guide plate 38 described above.

The bar 44 on the lower side is the wire inserted in the wire tube 45.
It is connected to a link 48 that is integral with the operating lever 47 via 46. By rotating the operating lever 47 in the direction of the arrow in FIG. 3, the lower bar 44 is slid and displaced, whereby the upper bar is moved. 43 is designed to move up and down. As a result, the rear hook plate 33 rotates about the hinge pin 35 as the center of rotation via the guide plate 38 and the cam lever 39 according to the vertical displacement of the upper bar 43.

In other words, the front hook plate 32 of FIG. 4 is always held at a height position where it can be engaged with the launcher slipper 17 by being biased by the torsion coil spring 36.
Although the rear hook plate 33 is biased by the torsion coil spring 36, the rear hook plate 33 can be engaged with the launcher slipper 17 according to the vertical movement of the guide plate 38 as described above.
It is possible to selectively switch between P ₂ and the disengagement position P ₁ . Then, the above-mentioned guide plate 38, bars 43, 4
4, the link levers 41 and 42, the wire 46, the operation lever 47, and the like constitute a switching operation mechanism 49 for the rear hook plate 33.

Next, the operation of the loading device configured as described above will be described.

First, as shown in FIG. 2, the loading device 1 in which the processing bullets 8 are positioned and fixed in advance is lifted from the carrier 2 by the crane 3, the legs 9 thereof are landed on the tracked vehicle 5, and the loading rail 7 Is connected to the front end of the launcher 4, that is, the front end of the launcher rail 10 of FIG. As a result, as shown in FIG. 1, the launcher rail 10 and the loading rail portion 7 are provided.
And are in a straight line. Then, after releasing the locked state of the lock mechanism 28 that locks the processing cartridge 8, the operation handle 26 is rotated to shift to the loading operation of the processing cartridge 8.

At this time, as shown in FIG. 4, the rear hook plate 33 is held in advance at the release position P ₁ shown by the solid line by operating the operation lever 47. When the operation handle 26 is rotated (normal rotation), the crawler beam 13 connected to the crawler chain 21 is sent toward the launcher 4 as the lower crawler chain 21 travels, and the crawler beam 13 Following the movement, the crawler chain 16 on the upper side travels in the same direction. As a result, the hook member 18 connected to the crawler chain 16 advances toward the launcher 4 with a stroke twice that of the lower crawler chain 21.

When the hook member 18 advances, the front hook plate 32 engages with the launcher slipper 17 of the processing bullet 8 as shown in FIG. It is gradually pushed into the projectile storage unit 4a of the launcher 4 along the line 10.

When the processing bullet 8 is pushed to the deepest part of the launcher 4 as shown in FIGS. 6 and 7, the operation handle 26 is reversely operated. As a result, the crawler chain 16 on the upper side travels in the opposite direction, and the front hook plate 32 autonomously separates from the launcher slipper 17 and returns to its original position. As described above, the loading of the processing bullet 8 is completed.

On the other hand, in the case of pulling out the processing bullet 8 once loaded in the launcher 4, the hook member 18 is sent to the stroke end of the projectile housing portion 4a with a so-called empty load in the same procedure as described above. At this stroke end position, the operating lever 47 shown in FIG. 3 is rotated to switch the rear hook plate 33 shown in FIG. 4 to a height position (P ₂ position) at which it can be engaged with the launcher slipper 17. After that, when the operation handle 26 is reversely operated, the rear hook plate 33 is engaged with the launcher slipper 17, and the processing bullet 8 is pulled by the rear hook plate 33 and pulled out from the launcher 4.

Here, in the above embodiment, the hook member 18 including the front hook plate 32 and the rear hook plate 33 is used as the engaging member that engages with the launcher slipper 17,
Instead of this, for example, a pin hole may be formed on the launcher slipper 17 side, and a pin-shaped member that engages and disengages with the above-mentioned pin hole by the retracting operation may be used.

However, in the previous embodiment, it is not necessary to switch the rear hook plate 33 by the operating lever 47 unless the processing bullet 8 is pulled out, whereas when the above-mentioned pin-shaped engaging member is used, It is necessary to retract the pin-shaped member.

EFFECTS OF THE INVENTION As described above, according to the present invention, the projectile is loaded while sliding the projectile from the one end surface of the launcher in the axial direction thereof. There is no need to ride on the road, the operator can be freed from work at a high place, and safety is improved, and even if the terrain of the loading place is a little sloping ground, the loading work can be performed without difficulty.

Furthermore, not only can the projectile be loaded into the launcher, but its withdrawal can be done without difficulty in the same manner as when loading,
The flexibility of the equipment as a loading device is increased.
