Description

The invention relates to rocket and space technology, and more particularly to ground handling equipment, and can be used in the preparation of launch vehicles for launch at a highly automated launch complex.

Known rocket installer, which contains a frame with a chassis mounted on the frame with the possibility of rotation in the longitudinal vertical plane, an arrow with supports for mounting a rocket equipped with an aiming device, and a hydraulic drive for turning the arrow (see the book "Cosmodrome" under the editorship of A.P. . Volsky, - M., "Military Publishing", 1977 - S.112-113 fig. 4.12, S.240-247 fig. 8.7). Although this well-known installer allows you to ensure that the launch vehicle is placed in a vertical position on the launch pad and to prepare the rocket for launch, it is of poor performance especially during the operation of aiming the rocket in sunny weather, as the sun's rays and their reflections reduce the accuracy of aiming .

Also known is a unit for transporting, lifting and installing a launch vehicle in a vertical position, which includes a chassis, a frame, a rotary boom with attachment points for the rocket, and a boom lifting mechanism (see the book "Cosmonautics", encyclopedia, edited by V.P. Glushko, - M .: "Sov. Encyclopedia", 1985 - P.407, 418). The use of the known unit provides for the ground operation of the rocket (its assembly, crane loading, transportation) in a horizontal position, and the rocket is raised to a vertical position during installation at the launch site.

The main disadvantages of the known unit, taken as a prototype, are the effect on the rocket during ground operation of significant loads that do not correspond to flight loads, which leads to an additional strengthening of the rocket design, and this leads to an undesirable increase in its weight, as well as low operational characteristics, concerning the versatility and automation of the application of the unit during the launch of launch vehicles.

The basis of the invention is the task of improving the design of the proposed device, which would allow for improving the performance and versatility of the use of this unit by introducing new structural elements and technical solutions to ensure the automated launch of medium and heavy class launch vehicles.

The problem is solved in such a way that in the proposed device for lifting and holding the installer with the launch vehicle in a vertical position, including a frame supported by a launching structure, an arrow pivotally connected to the frame and equipped with a hydraulic cylinder for raising and lowering it, hydro and electrical equipment, the frame is made in the form of a base fastened with a concrete launching structure, and two longitudinal beams of a box-shaped section of a triangular shape, interconnected by a transverse beam. At the same time, bonks are welded into the longitudinal beams for fastening the lower axis of the lifting and lowering hydraulic cylinder, and eyelets with holes for fastening the axes of rotation of the boom, consisting of two longitudinal beams, a tail beam and transverse beams, are made at the upper ends of these beams. Moreover, bonkos are welded into the longitudinal beams of the boom for attaching the upper axis of the mentioned hydraulic cylinder and bonkos for attaching the boom to the frame. And on the transverse beams of the boom, a carriage is installed, consisting of the frame itself and two rods, fastened together in a rigid frame structure and serving as guides when moving the carriage frame along the boom using its own hydraulic cylinder attached to the eyes of the boom and carriage.

In a horizontal position, the boom is supported on supports fixed on the concrete base of the launching structure, at the zero point of which is located the boom flooring, on the longitudinal beams of which there are rails that are joined with the rails of the launching structure, and parallel to the rails are installed guides that center the installer with the launch vehicle at hitting him on an arrow.

Brackets and rails are additionally installed on the boom, made in the form of C-shaped grips to hold the installer with the booster rocket on the boom, and in the deck of the latter, hatches are made for servicing the hydraulic cylinders for moving the carriage and lifting (lowering) the boom, closed by covers.

To explain the design of the device for lifting and holding the installer with the launch vehicle on the launch pad and its operation, the drawings are attached, which depict:

The proposed device for lifting and holding the installer 1 with the launch vehicle 2 on the launch pad 3 in an upright position includes a frame 4, an articulated boom 5, provided with a hydraulic cylinder 6 for raising and lowering it, as well as hydraulic and electrical equipment (conditionally not shown in the drawings).

The frame 4, which is a welded forged structure, consists of a base 7, bonded to a concrete launching structure 8, and two longitudinal beams 9 of a box-shaped section of a triangular shape, interconnected by a transverse beam 10.

Bonks are welded into the longitudinal beams 9, intended for fastening the lower axis 11 of the hydraulic cylinder 6 for raising and lowering the boom 5, and the eyes 12 are made in the upper ends of these beams with holes for mounting the axes of rotation of the boom.

The boom 5 is a welded forged structure consisting of two longitudinal beams 13, a tail beam 14 and transverse beams 15. Bonks are welded into the longitudinal beams 13 for fastening the upper axis 16 of the hydraulic cylinder 6 and bonks for attaching the boom 5 to the frame 4.

On the transverse beams 15 of the boom 5 mounted carriage 17, consisting of the actual frame 18 and two rods 19.

The rods 19 are fastened together in a rigid frame structure and serve as guides when moving the frame 18 of the carriage 17 along the boom 5 using its own hydraulic cylinder 20 attached to the eyes of the boom 21 and the carriage.

In a horizontal position, boom 5 is supported on supports 22 fixed to the concrete base of the launch structure 8, and at the level of the zero mark of the latter, boom flooring 23 is located.

Rails 24 are laid on the longitudinal beams 13 of boom 5, which are joined to the rails of the launch structure 8. Parallel to the rails 24, guides 25 are installed that center the installer 1 with the launch vehicle 2 when it hits the boom 5.

To hold the installer 1 with the launch vehicle 2 on the boom 5, brackets 26 and guides 27 are additionally installed on it, made in the form of C-shaped grips.

To service the hydraulic cylinder 6 of the rise (lowering) of the boom 5 and the hydraulic cylinder 20 of the carriage 17 in the deck 23 of the boom, hatches 28 are made, closed by covers 29.

The device operates as follows. After rolling the installer 1 with the launch vehicle 2 on the boom 5 to the docking position with the carriage 17, the latter is moved by the hydraulic cylinder 20 towards the installer and fixes it on the boom.

Then, in reverse stroke of the hydraulic cylinder 20, the carriage 17 moves the installer 1 with the launch vehicle 2 to the docking position of the units of the communication devices of the installer's communications with the ground complex, while the protrusions of the installer go into the grooves of the guides 27 and the brackets 26 and position the installer with the launch vehicle on the boom 5 .

Then the boom 5 with the installer 1 and the launch vehicle 2 by means of the hydraulic cylinder 6 rises to a vertical position, after which the carriage 17 by means of the hydraulic cylinder 20 lowers the installer with the launch vehicle to the supports of the launch pad 3.

After the prelaunch preparation of the launch vehicle 2, the arrow 5 with the installer 1 is retracted by a hydraulic cylinder 6 to an angle of 24 degrees from the vertical position, while the launch vehicle remains on the supports of the launch pad 3.

And after the launch of the launch vehicle 2, the arrow 5 with the installer 1 by means of the hydraulic cylinder 6 is returned to the vertical position.

After post-launch work, the boom 5 with the installer 1 by means of the hydraulic cylinder 6 is lowered to a horizontal position, and the carriage 17 by means of the hydraulic cylinder 20 moves the installer 1 to the undocking position with the carriage. Then the installer 1 is rolled back from the boom 5.

Thus, the proposed device can significantly improve the performance, reliability and versatility of use of this unit, as well as provide automated launches of medium and heavy class launch vehicles from a ground launch facility.
