In the embodiments shown in these drawings, a launcher receiver 2 is fixed on a vehicle body 1 of a crawler type or wheel type traveling vehicle.
A bearing box 3 in which a bearing 4 and a bearing box outer side 5 which is a swivel body are assembled is fixed to the firing tube receiver 2 with bolts. The bearing housing outer side 5 is attached so as to be rotatable around a central axis Y-Y passing through the center O of the launcher receiver 2 via the bearing 4.
[0010]
A firing tube stopper 6 is attached to the center of the upper portion of the firing tube receiver 2 with a bolt.
On the rear side of the bearing box outer side 5, a turning operation mechanism 7 for the bearing box outer side 5 is attached. The turning operation mechanism 7 includes a fan-shaped worm wheel 8 fixed to the upper surface of the bearing housing 3 with bolts, a worm 9 provided on the shaft 10 and meshed with the worm wheel 8, and a handle 11 attached to the shaft 10. And is configured. The shaft 10 is rotatably supported by a support base 13 via a bearing 12. Therefore, this turning operation mechanism 7 can rotate the bearing housing outer side 5 through the shaft 10, the worm 9, and the worm wheel 8 by the angle Ψ in the left-right direction in FIG. 1 by rotating the handle 11 in the forward direction or the reverse direction. It has become.
[0011]
Four-bar links 14 and 15 are attached to the bearing housing outer side 5 from the left and right sides toward the front and the upper side. The two sets of four-bar links 14 and 15 are configured to have links 16 and 17 arranged at intervals in the front-rear direction. In these links 16 and 17, the length of the link 17 disposed on the front side is longer than the length of the link 16 disposed on the rear side, and the length is horizontal in a state in which a launch tube 36 described later is stored. (Or almost horizontal). Of the links 16 and 17 of the four-bar links 14 and 15, the rear link 16 is pin-coupled to brackets 18 provided on the left and right at the upper end of the bearing housing outer 5, and the front link 17 is connected to the bearing housing outer 5. Are connected to brackets 19 provided on the left and right at the front end of each of the front end portions, and are respectively rotatable.
[0012]
The base 20 is pinned across the upper sides of the two sets of four-bar links 14 and 15, that is, the upper ends of the links 16 and 17 of the four-bar links 14 and the upper ends of the links 16 and 17 of the four-bar links 15. Combined, each can rotate. As described above, since the length of the link 17 is longer than the length of the link 16, a non-parallel four-bar link is formed in a state where the base 20 is pin-coupled across the upper ends of the links 16 and 17. For this reason, the base 20 forms an angle α with respect to the horizontal. Further, the right end of the base 20 shown in the figure sufficiently protrudes from the position of the pin coupling with the link 17 so that a guide rod can be moved when the launcher is stored, which will be described later.
[0013]
Between the front end portion of the bearing housing outer side 5 and the lower portion of the base 20, a screw jack 21 of a drive mechanism for moving the base 20 up and down and back and forth by deforming and driving the link shape formed by the four-bar link 15 and its operation Means 22 are provided. The operating means 22 includes a mechanism 23 that rotates a rotating portion of the screw jack 21, a shaft 24, and a handle 25. For example, a worm wheel and a worm are used as the mechanism 23 for rotating the rotating portion of the screw jack 21. Accordingly, the operating means 22 rotates the handle 25 in the forward direction or in the reverse direction to rotate the rotating portion of the screw jack 21 in the forward direction or the reverse direction via the shaft 24 and the mechanism 23 that rotates the rotating portion of the screw jack 21. And the screw jack 21 can be extended or reduced. The link 24a is interposed between the link 15 and the shaft 24, and ends thereof are rotatably coupled to each other.
On the base 20, slide shifters 26 and 27 are installed. The slide shifters 26 and 27 are fixed on the base 20 at intervals in the left-right direction and attached so as to be movable along guide rods 28 and 29 that are long in the front-rear direction.
[0014]
FIG. 3 is a partially longitudinal enlarged view of FIG. 2 viewed from the A direction. As shown in the figure, a plate 30 is attached to the lower part of the slide shifters 26 and 27. Accordingly, the plate 30 can move in the front-rear direction together with the slide shifters 26 and 27.
A pin 31 is fixed to the plate 30 vertically at the center in the left-right direction. A holder 32 for receiving a firing tube is attached to the pin 31 so as to be rotatable around the pin 31 on the plate 30.
[0015]
The holder 32 is provided with pins 33 and 34 on both the left and right sides. These pins 33 and 34 are provided on the same axis in the horizontal direction. A launcher receiver 35 is pivotally attached to the pins 33 and 34 so as to be rotatable about the pins 33 and 34 as rotation centers.
As shown in FIG. 2, the launch tube receiver 35 is connected to a support tube 37 a located at an intermediate portion of the launch tube 36 via a support rod 37. A handle 37b is attached to the support cylinder 37a. By rotating the handle 37b, the support cylinder 37a is moved vertically along the launch cylinder 36 by a worm wheel and a worm mechanism (not shown). . The lower end portion of the firing tube 36 is pivotally attached to the central portion of the firing tube stopper 6 via a ball joint 38.
[0016]
Between the launch tube 36 and the base 20, a first displacement absorbing mechanism that absorbs the horizontal component of the displacement of the support rod 37 when the vertical angle φ of the launch tube 36 is adjusted, and the angle in the turning direction of the launch tube 36. There is provided a second displacement absorbing mechanism that absorbs the displacement in the turning direction of the launch tube 36 that occurs when the launch tube 36 moves around the launch tube stop 6 when adjusting θ.
[0017]
The first displacement absorbing mechanism includes guide rods 28 and 29 fixed on the base 20 at an interval in the left-right direction, and a slide shifter 26 provided so as to be movable along the guide rods 28 and 29 in the front-rear direction. , 27. The first displacement absorbing mechanism allows the slide shifters 26, 27 to move in the front-rear direction through the support rod 37, the launcher receptacle 35, the holder 32, the pin 31, and the plate 30 when the vertical angle φ of the launcher 36 is adjusted. The horizontal component of the displacement of the support rod 37 is absorbed.
[0018]
The second displacement absorbing mechanism includes a plate 30, a pin 31 that is vertically fixed on the plate 30, a holder 32 that is rotatably attached to the pin 31, and a pin that is provided on the holder 32. And a launcher receiver 35 pivotally attached to 33, 34. When the angle θ in the turning direction of the launch tube 36 is adjusted, the second displacement absorbing mechanism rotates the vertical displacement of the launch tube 36 around the pins 33 and 34 provided with the launch tube receiver 35 in the horizontal direction. Thus, the displacement of the launch tube 36 in the turning direction can be absorbed by rotating the launch tube receiver 35 and the holder 32 around the pin 31 provided in the vertical direction.
[0019]
The launch tube 36 is provided with a fine adjustment mechanism for the angle θ in the turning direction and a fine adjustment mechanism for the angle φ in the vertical direction.
As shown in FIG. 1, the fine adjustment mechanism for the angle θ in the turning direction is arranged on the base 20, fixed at intervals in the front-rear direction and long in the left-right direction, and both guide rods 39, 40, a screw rod 41 provided between the screw rods 41, a nut 42 screwed into the screw rod 41 and movable along the guide rods 39, 40, and a handle 43 attached to the screw rod 41. The support rod 37 is attached to the nut 42. The fine adjustment mechanism for the angle θ in the turning direction rotates the handle 43 in the forward direction or the reverse direction, so that the nut 42 is moved in parallel in the left-right direction by the screw action of the screw rod 41 and the nut 42. As the nut 42 moves, the launch tube 36 can be finely adjusted in the turning direction via the support rod 37.
[0020]
The fine adjustment mechanism of the angle φ in the vertical direction rotates the handle 37b in the forward direction or the reverse direction, so that the support cylinder 37a moves up and down along the central axis of the launch cylinder 36, and the support rod 37 also moves. The vertical angle θ of the launch tube 36 can be finely adjusted about the center O of the launch tube receiver 2 by the vertical component of the displacement generated thereby.
The launcher support device according to the above configuration is operated and operated as follows.
[0021]
That is, when the angle θ in the turning direction of the launch tube 36 is adjusted, the handle 11 of the turning operation mechanism 7 for the outside of the bearing box is rotated in the forward direction or the reverse direction. As described above, when the handle 11 is rotated in the forward direction or the reverse direction, the outer side of the bearing housing 5 is rotated around the central axis YY of the launcher receiver 2 through the shaft 10, the worm 9, and the worm wheel 8. Rotate counterclockwise or counterclockwise. When the bearing housing outer side 5 is rotated clockwise or counterclockwise, the four-bar links 14 and 15 are rotated clockwise or counterclockwise together with this, and accordingly, the base 20 and its attached members and Through the support rod 37, the launch tube 36 turns clockwise or counterclockwise. Thereby, the angle θ in the turning direction of the launch tube 36 can be adjusted.
[0022]
Thereafter, when the angle θ in the turning direction of the launch tube 36 is finely adjusted, the handle 43 of the adjustment mechanism of the angle θ is rotated in the forward direction or the reverse direction. When the handle 43 is rotated in the forward or reverse direction, the screw rod 41 is rotated in accordance with the rotation direction of the handle 43, and the nut 42 is moved leftward or rightward by the screw action of the screw rod 41 and the nut 42. The launch tube 36 moves slightly in the turning direction through the support rod 37 attached to the nut 42. Thereby, the angle θ in the turning direction of the launch tube 36 can be finely adjusted.
[0023]
At this time, the displacement in the turning direction caused by the movement of the launch tube 36 around the launch tube stop 6 is caused by the rotation of the holder 32 for receiving the launch tube around the pin 31 provided perpendicular to the plate 30. Absorb.
Further, when adjusting the vertical angle φ of the launch tube 36, the screw jack 21 which is the drive mechanism of the four-bar links 14 and 15 and its operating means 22 are controlled as follows. That is, when the handle 25 of the operating means 22 of the screw jack 21 is rotated in the forward direction or the reverse direction, the screw jack 21 is expanded or contracted through the shaft 24 and the mechanism 23 that rotates the rotating portion of the screw jack 21. As a result, the four-bar links 14 and 15 are raised or lowered, and at the same time, the support rod 37 is moved back or forth through the launcher receiver 35, the pins 33 and 34, the holder 32, the pin 31, the plate 30 and the slide shifters 26 and 27. The firing tube 36 moves upward or downward with the central portion of the firing tube stopper 6 as a fulcrum. Thereby, the vertical angle ¢ of the launch tube 36 can be adjusted.
[0024]
Thereafter, when finely adjusting the vertical angle φ of the launch tube 36, the handle 37b is rotated in the forward direction or the reverse direction. When the handle 37b is rotated in the forward direction or the reverse direction, the vertical angle φ of the launch tube 36 is finely adjusted by a drive mechanism including a worm wheel and a worm (not shown).
That is, the support cylinder 37a is moved upward or downward by the action of a drive mechanism constituted by a worm wheel provided in the launch cylinder 36 and a worm that meshes with the worm wheel and rotates according to the rotation direction of the handle 37b. The launch tube 36 slightly moves up and down via the support rod 37 attached to 37a. Thereby, the angle θ in the vertical direction of the launch tube 36 can be finely adjusted.
The horizontal component of the displacement of the launch tube 36 at this time is absorbed by the movement of the slide shifters 26 and 27.
[0025]
Next, the reason why the operating force is reduced when the vertical angle θ of the firing cylinder 36 is finely adjusted will be described with reference to FIGS. FIG. 4 is an explanatory view of the operation force of this embodiment, and FIG.
First, the conventional example of FIG. 5 will be described. F1 is a force generated by the rotating operation of the handle 37b (see FIG. 2). If this force is large, the force required for fine adjustment increases and the operation becomes heavy. F2 is a force when the launch tube 36 is lowered about the ball joint 38, F3 is a force necessary to support the launch tube 36, and has a relationship of | F2 | = | F3 |. These F2 and F3 are at 90 ° with respect to a line connecting the silicide shifters 26 and 27 and the ball joint 38. F4 is a reaction force by the base 20 and is perpendicular to the base 20 because the base 20 slides back and forth. From the balance of forces, F1 and F3 and the quadrangle formed by the resultant force form a parallelogram.
[0026]
On the other hand, in the present embodiment of FIG. 4, the sizes of F2 and F3 are equal to those of the conventional example of FIG. However, the reaction force F6 from the base 20 is inclined by an angle α from the horizontal, and as shown in the figure, similarly, the component force F5 of F6 is also shown in the figure from the balance of forces, Form a parallelogram.
As is apparent from the figure, when F1 and F5 are compared, F1> F5, and it can be understood that in this embodiment, the operating force is reduced compared to the conventional example.
[0027]
According to the measured value of the operating force, in the present embodiment, the operating force of the handle 3 when the launch tube 36 is directed upward is 176 N (Newton) and 20 N when it is directed downward, in the present embodiment. The operating force was 88N when turned upward, 58N when turned downward, and when it was turned downward, it was reduced by half.
Further, in this embodiment, when the length of the link 17 is longer than that of the link 16, when the vertical angle θ of the link 16 is about 9.4 °, the angle φ + α when the launch tube 36 is stored becomes 0 °. As a result, the launch port could be lowered to the same height as the conventional example.
[0028]
As can be seen from the above description, in the present embodiment, the launch tube 36 can be mounted and used on the vehicle body by adding only a few parts for in-vehicle use without any modification.
Further, in the present embodiment, the vertical angle φ of the launch tube 36 can be adjusted over a wide range of 45 °, for example, after being used in a vehicle.
Furthermore, in this embodiment, since the launch tube 36 is supported by the four-bar links 14, 15, the tilt tube 36 and its support device can be held in a low posture by tilting the four-bar links 14, 15, The launch tube 36 can also be stored in the vehicle.
In the above embodiment, instead of the set of the screw jack 21 and its operating means 22 as a drive mechanism for moving the base 20 attached to the four-bar links 14 and 15 in the vertical and longitudinal directions, a hydraulic jack and its operation are used. Means may be used.
[0029]
