(54) DEVICE FOR PIPING CONTAINER PNEUMOTH

This is achieved by the fact that in a device for pipeline container pneumatic transport, which contains a pipeline with acceleration and deceleration sites for larger cross-sections and container structures moving inside it, equipped with transverse cuffs and wheel travel, the containers are equipped with additional transverse cuffs designed to move perpendicular to the axis of the pipeline, while ensuring the overlap of the cross section of the pipeline along the entire route, and the junction of The pipeline of different cross sections is smooth.

FIG. 1 shows a device for the pneumatic transportation of goods in containers through a pipeline. round section, general view; in fig. 2 - the same, section along AA (on an enlarged scale); in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a device for the pneumatic transportation of goods in containers through rectangular pipelines, a general view; in fig. 5 - the same, section bb.

The device for pipeline container pneumatic transport consists of a main pipeline 1, inside which container trains 2 are moved on the wheel. The pipeline is connected by a pipe 3 with a formidable section 4 of the pipeline, made of pipes of a larger cross section than the main pipeline 1. As section 4, which requires an increase in tractive effort to overcome it, can be viewed from the pipeline ascent section stopping it at the place provided for this purpose (for example, at loading, unloading stations, etc.). Also, the section for stopping the composition when using air braking can be considered as a similar area requiring a more effective impact on the container composition of the air mass. The connection of the pipeline 1 with the section 4 is carried out so that the lower forming main pipeline 1, the pipe 3 and the section 4 is a straight line. At the same time, the pipe axis of section 4 is mixed upwards relative to the axis of the main pipe 1.

For a round section pipe, composition 2 consists of cargo containers 5 and a pneumatic truck 6. On a pneumatic truck b, the main transverse cuffs 8 are located in the plane of the axle of the traveling wheels 7, which overlaps the pipe section as the composition moves along the main pipeline 1. on section 4, the pneumatic locomotive 6 is provided with additional transverse cuffs 9 of them, which are spring-loaded, moving in the radial direction relative to the disk 10 fixed on the body 11 of the pneumatic assembly and 6, sector elements 12 disposed staggered on both sides of the disc 10. The construction sector elements 12 provides a sufficient stroke to overlap the enlarged cross-section in the pipe conduit 3 and 4. At the portion 12 of sector elements rigidly fixed

rollers 13, which rotate on the axes, which, when the pneumatic truck 6 is moving, the internal configuration of the pipeline ensures that the cross section of the pipeline is overlapped by the cuff 9 in the nozzle 3 and in section 4, maintaining a constant structural gap between the inner wall of the pipeline and the cuff 9. This gap excludes friction cuff 9 on the pipe wall and its wear. In a rectangular section pipe, composition 2 consists of containers 14, on the case of which transverse cuffs 15 are placed. These cuffs in the upper part of the container have part 17 pivoting from the hydraulic or pneumatic actuator 16, compensating for an increase in the section of the pipeline by increasing its height.

5 Turning on the actuator 16 is performed from a linear sensor (not shown) mounted on conduit 1 before entering part 2 into section 4, and disabling the actuator 16 and returning part 17 of the cuff 15 to its original position for movement along the main conduit from the linear encoder (not shown) installed at the end of section 4. The cuff 15 in the upper part of the container can be made similar to element 12 - in

5 as a spring-loaded sliding element (not shown in the drawing).

The device for pipeline container pneumatic transport works as follows.

0 When entering the composition of 2 containers into the pipe 3 and into the section 4 and moving along it the spring-loaded elements provide the overlap of the pipe 3 that is enlarged against the main pipe 1 and the section 4.

In this connection, in section 4 (without an increase in pressure (vacuum) of the blower units and, consequently, without the need for a reserve of power of these units), composition 2 creates the necessary for lifting

0 composition or its acceleration traction effort. At the sections where the compositions are stopped, an increase in the cross section of the pipeline ensures effective pneumatic braking of the composition at a relatively lower air pressure before the composition. Necessary cross

5, the pipe section in section 4 is determined based on the calculated pulling force (braking force) required to overcome the composition of the lifting or accelerating section

composition (to stop the composition). At the same time, during the movement of the composition along section 4, other compositions located in the pipeline, including section 4 (in the direction of travel), continue to move without noticeable reduction in speed.

In the rectangular section pipe with the rotary part 17 of the transverse cuff 15, the necessary movement of the part 17 for overlapping the pipe section in section 4 is carried out from the actuator 16 by a linear sensor signal located in pipe 1 before entering part 2 into section 4. When leaving section 4 According to the signal from the linear sensor installed at the end of section 4, the actuator 16 is turned off, and part 17 is returned to its original position by a spring (not shown) of the actuator 16.
