Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in rocket launch pads, particularly mobile launch pads.

Conventionally, there have been rocket launch pads of the type shown in FIGS. 1 to 4, which are carried by being mounted on a vehicle or being towed. That is, in the figure, 1' is a flying object such as a rocket, 2' is an elevating boom, 5' is an elevating drive device, and 6' is a rotating base, which is driven to rotate by a rotating drive device (not shown).
A flying object 1' such as a rocket is equipped with a head slipper 9' at the center of the lower part of the forehead, and a pair of rear slippers 10' and 10'' at the lower part of the rear tail.
Both slippers 9' and 1 are on the elevating boom 2' side.
A head slipper rail 3' and rear slipper rails 4' and 4'' are fixed at positions corresponding to 0' and 10'', respectively, so as to guide and support the rocket or other flying object 1'. When the rocket or other flying object 1' is elevated, its rear part is attached to the stopper 11', and its sides are attached to the slipper rails 3', 4', 4'' and the rocket support 7' which is detachably supported by the elevation boom 2'. , 7''. The elevating boom 2' is supported on a swivel base 6' so that it can be raised and raised, and the swivel base 6' is supported on a vehicle 8' so that it can be rotated. Driven. The vehicle 8' has a function of carrying a flying object 1' such as a rocket on a tower.

Next, the drawbacks of the conventional method will be explained. The elevating boom 2' and both slipper rails 3', 4', and 4'' need to slide and support the flying object 1', such as a rocket, until it reaches a predetermined speed after launch, and therefore need to have a corresponding length. In general, the tip of the elevating boom 2' is constructed to protrude relatively from the vehicle 8' in order to ensure the required rail length, which has the following disadvantages.

(1) When launching from inside the launch site building 12', as shown in Figure 4, the loss of space 13' (shaded area) due to the protruding elevating boom 2' is large.

(2) Vehicle operation is not easy due to the protruding elevating boom 2'.

(3) The required storage space for the vehicle (starting device) garage is large.

The present invention aims to provide a rocket launch pad that eliminates such problems, and is composed of a rear slipper rail provided along the longitudinal direction and a slit extending along the longitudinal direction to the upper end. a cylindrical elevating boom that is capable of elevating; a guide rail provided along the inner longitudinal direction of the elevating boom; and a guide rail that is engaged with the guide rail by a sliding or rolling means; A rocket launcher comprising: a head slipper rail exposed to the outside through a slit; and a telescoping boom that is partially or wholly housed within the elevating boom so as to be able to protrude and retract. . That is, to explain the function of the present invention along with its operation, in the present invention, first, the rocket is attached with the elevating boom lowered while the telescoping boom is retracted. In this state, the telescopic boom is stored in the cylinder of the elevating boom, but the head slipper rail of the elevating boom is exposed from the slit of the elevating boom to support the head slipper of the rocket, and the rear slipper rail of the elevating boom is It supports the tail slipper of the rocket. Since the elevating boom is cylindrical, it has a large cross-sectional area and is structurally advantageous in addition to storing the retractable boom in a contracted state.

Next, lift the elevating boom to the launch angle, fix it at that angle, and then extend the telescopic boom. When lifting the elevating boom, the telescopic boom is retracted within the elevating boom and is short, so the mechanical moment is small. Therefore, the output of the drive device for raising and lowering can be small. When extending the telescopic boom, the telescopic boom is supported by a guide rail provided along the longitudinal direction inside the elevating boom, and the telescopic boom is pushed out via sliding or rolling means.
The head slipper rail of the telescopic boom is exposed through a slit that extends to the upper end of the elevating boom, and is pushed forward while supporting the rocket via the head slipper. At the moment after the rocket launches, the rocket is supported on the rear slipper rail of the elevating boom via the rear slipper of the rocket, and at the same time is supported on the head slipper rail of the telescopic boom via the head slipper of the rocket. It slides on the launch pad and pops out.

Since the present invention performs the above-mentioned functions, it has the following effects.

(b) Operations such as turning can be performed inside the launch site building with the telescoping boom retracted, and when the rocket is launched, the telescoping boom can be extended and projected outdoors for launch, making the space in the launch building very efficient. expensive.

(b) The telescoping boom can be moved and handled in a retracted state, making it easy to transport and handle.

(c) The hangar including the transport vehicle can be small.

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

FIGS. 5 to 8 show an embodiment of the telescoping mechanism of the present invention. The structure and operation of the elevating and elevating boom 2 regarding elevating, elevating and turning are as shown in the outline of the conventional boom, and the elevating and elevating boom 2 is elevated and rotated by each drive device. On the upper surface of the elevating boom 2, tail slipper rails 4 and 4A are fixed at positions corresponding to the tail slippers 10 and 10A of a flying object 1 such as a rocket. Groove-shaped guide rails 22 and 22A are each fixed to the inner side of the elevating boom 2 in the inward opening direction, and guide rollers 21 and 21A rotatably fixed to both outer sides of the telescopic boom 13 and side Guide roller 2
3. 23A in the vertical direction and horizontal direction (sideways) respectively.
We will guide you while regulating. A head slipper rail 3 is fixed to the upper surface of the telescopic boom 13 with its head exposed through a slit 31 provided on the upper surface of the elevating boom 2 corresponding to the position of the head slipper 9 of the flying object 1 such as a rocket. Ru. A rack 24 is fixed to the lower outer surface of the telescopic boom 13 in the extending and retracting direction, and engages with a gear 25 rotatably supported by a bearing 27 and a bearing 27A supported by the elevating boom 2. The shaft of the gear 25 is coupled to the rotating shaft of a telescopic drive device 29 fixed to the corresponding elevating boom 2 through a coupling 28 . A telescopic stopper 30 and a telescopic stopper 30A are fixed to the inner surface of the elevating boom 2, and a protrusion (not shown) is fixed to the position of the telescopic boom 13 corresponding to the maximum extension and contraction to lock the boom. At the normal telescopic stop position, the telescopic drive device 29 is stopped slightly before the locking point by the operation of a position detector (not shown). The telescopic drive device 29 incorporates a brake device (not shown).

Next, the effects of the above embodiment will be explained.
As shown in FIG. 5, after setting the elevating boom 2 to a predetermined turning position and elevating angle with the telescopic boom 13 retracted, the rotation of the telescopic drive device 29 is easily controlled.
4 and gear 25, the telescopic boom is converted into a linear motion and protrudes. A position detector is activated slightly before the maximum extension, and the telescopic drive device is stopped, and the brake device is activated to stop the telescopic boom 13.

When the flying object 1 such as a rocket is elevated, its rear part is stopped and supported by a stopper 11, and the rear slippers 10, 10A, and head slipper 9 of the flying object 1 such as a rocket are fixed to the elevating boom 2 and the telescopic boom 13, respectively. When loaded on the rear slipper rails 4, 4A, and the head slipper rail 3, the head slipper rail 3 expands and contracts while sliding with the head slipper section. The telescopic boom 13 is the guide roller 2
1. 21A and side guide roller 23, 23
Due to the action of A, the guide rails 22 and 22A extend and contract with high precision while being regulated. In the above embodiment, the elevating boom 2 and the telescopic boom 13 have square cross sections, but they may also be circular. Further, the head slipper rail 3 only needs to be exposed from the slit 31 and engaged with the head slipper 9, and there is no particular need for it to protrude.

As described above, the telescopic boom 13 extends and contracts with respect to the elevating boom 2, and it is only necessary to extend them when launching a flying object 1 such as a rocket, so as shown in FIG. becomes very small. Also, as shown in Figure 5, the launch pad mounted on vehicle 8 is extremely small, so vehicle 8
It also has the advantage of being compact and easy to transport and handle.
