Description

The invention relates to mounting and docking equipment, and more particularly to stationary stands for assembling parts of rocket and space carriers, and can be used in the rocket and space industry for assembling and docking the head unit with a launch vehicle in a horizontal position.

A known unit for docking the warhead with a launch vehicle in an upright position, containing a frame on which an arrow is pivotally mounted with tool holders, an average adjustable support for laying the launch vehicle and means for securing the latter. The front end of the boom is made in the form of two parallel beams connected by a transverse beam. Paired brackets are fixed on the beams, the front pair of which is equipped with a lifting beam in a vertical plane with a remotely controlled lifting device with a load-gripping unit. At the same time, the rear pair of brackets is equipped with a mounting plate rotatable in the vertical plane, suspended on rigid rods to the axes located on the brackets (RF patent No. 2249547, class B64G 5/00, B66C 1/68, published in bulletin No. 10 of 10.04 .2005).

As a result of the analysis of the design of the above-described unit, it was revealed that during the operation it does not limit the vertical docking force, which complicates the docking process and cannot prevent possible damage to the carrier rocket seals located in its landing groove.

A known stand for docking, for example, the head part with a launch vehicle in an upright position, containing a frame with racks and supports for abutting parts of the product. The supports are made adjustable in height and mounted at one end of the two-arm levers pivotally mounted in the uprights with the possibility of swinging in vertical planes. At the second ends of the two-arm levers supported on the frame, elastic elements are installed that interact with the swinging levers placed above the two-arm levers. Moreover, the middle parts of the swinging levers are connected with the frame by lanyards intended for preliminary preloading of the elastic elements (RF patent No. 2402469, class B64G 5/00, F42B 1/36, published in bulletin No. 30 of 10/27/2010). This technical solution is the closest analogue to the proposed invention, therefore, it is taken as a prototype.

The disadvantages of the prototype include the low performance of the stand, the complexity of the design of the bench equipment, the low reliability of the docking work with units of rocket and space technology.

The objective of the invention is to improve the performance and characteristics of the assembly stand of the head unit with high reliability of assembly work on the docking (undocking) of the head unit to the launch vehicle.

The problem is solved in that in the proposed stationary assembly stand of the head block of the space rocket carrier, containing a power frame fixed to the foundation using anchor fasteners, a load-lifting boom with a device for placing and fastening the head block with it, lifting cylinders and lowering the boom, hydraulic supply system, electrical equipment and a service platform equipped with a fence along its perimeter, the power frame is made in the form of a box rectangle echeniya with projecting nodes for connection with the boom and the hydraulic cylinders. The device for placing on the boom and fastening the head block with it is made in the form of a truss of a tubular structure having the shape of a reverse truncated cone and fastened with an arrow using a slewing ring made in the form of a hollow cylinder with holes for bolts at each end of it. At the same time, a landing hole for the assembled head block is formed on the upper end ring of the farm, and a rotation bearing is fixed on the arrow, which has a rectangular shape with a hole in its central part. The hydraulic cylinders for raising and lowering the boom are pivotally connected via axles to the power frame and to the boom, which is supported in horizontal and vertical positions on the stops attached to the power frame.

The electric equipment of the stand is equipped with gear motors mounted on brackets fastened with an arrow to ensure rotation of the support ring of the truss by means of a gear mounted on the shaft of the gear motor.

The service platform, fixed to the foundation, consists of a central platform equipped with staircases for lifting personnel to the installation areas and for moving to the left and right side platforms equipped with retractable ladders.

The stand is equipped with a ladder that provides access for maintenance personnel to the inner aperture of the tubular structure farm.

The invention is illustrated graphically, where the drawings depict:

- figure 1 is a top view of the proposed device;

- figure 2 is a section aa of figure 1 (view of the stand in plan);

- figure 3 is a view B of figure 1;

- figure 4 - remote element In figure 2;

- figure 5 is a General view of the service areas;

- figure 6 is a view of the ladder;

- Fig.7 is a view of the proposed stationary stand assembly.

The claimed stationary assembly stand contains a power frame 1 mounted on the foundation using anchor fasteners, a lifting boom 2 with a device for placing and fastening the head unit G pivotally attached to it, hydraulic cylinders 3 for raising and lowering the boom, a service platform D equipped with a guard its perimeter, hydraulic power system and electrical equipment (the latter are conditionally not shown in the drawings). The power frame 1 is made in the form of a box-shaped rectangle with protruding nodes E for fastening with an arrow 2 and hydraulic cylinders 3.

The device for placing on the boom 2 and fastening the head block G with it is made in the form of a truss 4 of a tubular structure having the shape of a reverse truncated cone and fastened with an arrow using a slewing ring 5 made in the form of a hollow cylinder with holes for bolts 6 on each his butt. On the upper end ring 7 of the farm 4, a seat is formed for the assembled head unit G, and on the boom 2, which has a rectangular shape with a hole in its central part, a rotation bearing 8 is fixed.

In this case, the hydraulic cylinders 3 for raising and lowering the boom 2 are pivotally connected by means of the axes 9 to the power frame 1 and to the boom, which rests in the horizontal position on the stops 10, and in the vertical position - on the stops 11 fastened to the power frame.

The electrical equipment of the stand is equipped with gear motors 12 mounted on brackets 13, fastened with an arrow 2 to ensure rotation of the truss 4 by means of gears 14, mounted on the shaft of the gear motor.

The service platform D of the stand, equipped with a fence installed around its perimeter, is fixed on the foundation and consists of a central platform 15 equipped with ladder passages 16 for lifting personnel to the installation areas and for going to the side left 17. and right 18 platforms equipped with retractable ladders 19 .

In addition, the stationary stand is equipped with a ladder 20, providing access for maintenance personnel to the internal opening of the truss 4 of a tubular structure.

The stationary assembly stand of the head unit operates as follows. After the head unit is delivered to the test assembly housing, the boom 2 with the slewing ring 5 is moved to the vertical position. The head unit G, placed on a movable stand, is brought close to the stationary stand, the flange of the head unit is fastened with a slewing ring 5. Then the movable stand of the head unit is removed from the stationary stand and the hydraulic cylinders 3 return arrow 2 with the head unit G fixed to it transferred to a horizontal position for further maintenance of the head unit.

Access to service areas is provided from service sites D. For ease of maintenance, the head unit G located on the farm 4 is rotated, while the latter is rotated using 2 gear motors 12 by means of gears 14 and a rotation bearing 8.

After performing work with the head unit, the farm 4 returns to its original position, the boom 2 is translated into a vertical position. Then let down the movable stand and carry out the detachment of the flange of the head unit from the slewing ring 5 of the stationary stand. Then the movable stand is diverted from the stationary stand.

Thus, the present invention can significantly improve the performance, reliability of the assembly of the head unit and provides the versatility of the use of this stationary stand for the assembly of various units of rocket and space technology.
