Description

The invention relates to the field of mechanical engineering, in particular to tooling, which is used to fix products at the stage of their production and can be used in the oil, gas and nuclear industries in the manufacture of devices.

Known transport - launch platform for launching a launch vehicle from the surface of the water. Containing a rigid frame consisting of two sections, fixed lodgment supports, a movable carriage mounted on two carriages equipped with jacks, folding bandages, rubber-metal shock absorbers mounted on lodgment supports, a carriage and folding bandages, a device for keeping the rocket from longitudinal movements and guides supports (application for invention No. 95111717, IPC F41F 3/00, published on 06/27/1997)

The disadvantage of this platform is the low operational reliability.

A system for the manufacture and transportation of prefabricated parts is known, which contains one or more production and transport lines, each of which consists of a transport trolley, a transport guide, a lifting trolley from a manufactured part and a climbing rail (patent No. CN 105480662, IPC B65G 35/00, published 04/13/2016).

The disadvantage is the complexity of the installation of equipment.

The technical problems to be solved by the invention are the minimization of the weight and size characteristics of components and parts, the independence of the supporting frames and racks, the collapsible connection between the racks, the possibility of subsequent assembly and use without losing the properties of the supporting composite structures.

The tasks are solved due to the fact that the platform for assembling and loading the superheater into the housing contains lodgements for installing and fixing the housing, a rail support, racks of support grids, rope racks, hand winches, a supporting composite structure consisting of frames, racks of the first two frames, racks of the subsequent frames, roller bearings, screw jacks and couplers, equipped with equipment that can be dismantled and removed assemblies and parts of the supporting composite structure, and the lodgements can be adjusted in height, each frame consists of three parts, one central and two lateral parts the frames are connected to each other by means of a flange connection with a centering cylinder, the racks and frames are connected by removable couplers, and screw jacks are installed on the top of each rack.

The manufacture of frames from three parts (central and two lateral) and the connection of the frame parts to each other using a flange connection with a centering cylinder makes it possible to remove the supporting composite structure manually from a limited space under the superheater casing.

Installation of screw jacks on the top of each rack, as well as height adjustment of the cradles, allows you to install the superheater in the desired position relative to the casing before it is inserted into the casing.

The connection of racks and frames with removable couplers allows you to transfer the pulling force of manual winches and provide a given distance between the frames.

The use of tooling for dismantling and extracting components and parts will allow you to safely remove components and parts without applying significant physical load on a person, as well as use the platform in subsequent product assembly operations.

The invention is explained in more detail with the help of drawings:

In FIG. 1 shows a general view of the installation;

In FIG. 2 - lodgment;

In FIG. 3 - rail support;

In FIG. 4 - bearing composite structure.

The platform for assembling and inserting the superheater into the housing contains a lodgement 1 (Fig. 1) for installing and fixing the housing, a rail support 2, a supporting composite structure 3, a support grid stand 4, a rope stand 5, and a manual winch 6.

Lodgment 1 (Fig. 2) consists of two mirror halves, interconnected by bolts 7. The position of lodgment 1 is adjusted in height with screws 8. Lodgment 1 has places for attaching a tie-down strap, pressure screws 9 serve to ensure the roundness of the body.

Rail support 2 (Fig. 3) is a frame consisting of I-beams 10 and channels 11, sections of welded rails 12, screwed together and pressed against the frame with clamps 13. is located below the reference plane along which the superheater is brought into the casing.

The supporting composite structure 3 (figure 4) consists of frames 15, racks 16 of the first two frames, racks 17 of subsequent frames, roller bearings 18, screw jacks 19 and couplers 20. Frames 16 consist of three parts - central and two side. Parts of frames 16 are interconnected by means of a flange connection with a centering cylinder 21. Racks 16 of the first and second frames are non-separable structures welded from channels. Racks 17 of the subsequent frames are collapsible and consist of three parts interconnected by a flange connection to reduce weight and facilitate removal from the body after assembly.

Each rack 17 at the base has a roller support 18 with minimal weight and size characteristics.

Screw jacks 19 are installed on the top of each rack. Racks 16, 17 and frames 15 are connected by removable couplers 20 to transfer traction to manual winches 6 (Fig. 1).

Support grid stand 4 is designed to install and hold the support grid in a vertical position.

The platform for assembling and winding the superheater into the housing works as follows.

A row of cassettes of 14 pieces is installed in the pre-installed and fixed support grid, after which the supporting composite structure 3 is brought in and supports the first row of cassettes. Next, the remaining rows of cassettes are installed. After assembling the wound product, the support grid is unfastened and the product is positioned in height with the help of screw jacks 19 of the supporting composite structure 3 to provide the necessary position relative to the body, which is preliminarily aligned with the rail support 2. After that, cables from manual winches 6 cling to the supporting composite structure 3, and the process of winding the product into the case begins. During the winding process, due to the fact that the dimension of the support grid is below the surface along which the supporting composite structure 3 moves, it is necessary to gradually dismantle sections of the rail support 2. After the product is wound up and fixed inside the housing, the supporting composite structure 3 is disassembled and removed from the housing using equipment , which provides for the minimization of human efforts and increases the safety of dismantling work inside the limited space of the case with the product.

Thus, the use of this platform will make it possible to use transport platforms of minimum dimensions with a simultaneous increase in the area of contact of the platform with the surface along which the superheater is assembled and inserted into the casing, as well as to dismantle and remove units and parts from a limited space and without applying significant physical load on person.
