The invention relates to the mining industry, in particular to equipment for transporting containers through pipelines in the development of mineral resources.

Known trunk grusovoi, including loading and unloading areas, cargo and single branch of the pipeline, forming a single closed loop, filled with the working environment, gateway camera and power unit (see RF patent №2186016, IPC7B65G 51/04, 53/12, E21F 13/08, publ. 27.07.2002,).

The disadvantage of this system is its low efficiency. This is because the freight branch of the pipeline on the part of a lifting filled with working liquid, which should contribute to spontaneous ascent of containers. However, for surfacing a significant part of the internal volume of the container should be filled with air, which reduces the efficiency of the process of transportation, or the density of working fluid must be very high in order to push the loaded container that will lead to significant expenses.

Closest to the claimed technical solution is a mountain transport, including loading and unloading areas, cargo and single branch of the pipeline, forming a single closed guide transport path, filled with the working environment, the gateway is the ameres and pneumatic pump (see RF patent №2207973, IPC7B65G 51/04, 53/12, E21F 13/08, publ. 10.07.2003 year).

The prototype has the same drawbacks as the analogue, as part of a lifting truck of the branch pipe is also filled with the working fluid. In addition, the end sections when the transition from one branch to another rounded design makes cumbersome and requires significant material costs. This is because to ensure the movement of the container in a circle turning radius must be large enough. Another disadvantage of the prototype is the joint use of drip and gaseous fluid, which is impractical due to the need for additional sealing of the pipeline and container.

The result of the proposed technical solution is to simplify the design, reduce material consumption, reduced size, improved reliability of the device and simplification of the process of transportation of materials in the development of mineral resources.

The technical result is achieved in that the pneumatic container transport, including loading and unloading areas, cargo and single branch of the pipeline, forming a single closed guide transport path, filled with the working environment, gateway cameras and pneumatic pump, according to the invention the guide Tran is tailoring the path made in the form of horizontal sections with loading and unloading areas, equipped with ejectors, and inclined sections, and at the discharge space cargo piping is located above the blank pipe, and a boot space below, and both branches of the transport path is made from two sides gradually converging in one point with the formation of the pair, while the branch pipe provided with a by-pass valve set at the beginning of the inclined sections and the flaps set at the beginning of the sloping ground and cargo and single branches, and as the working environment using compressed air.

Gateway camera is located at the intersection of cargo and single branches of the pipeline.

The discharge space provided with a tripper and unloading hopper and boot space hopper.

This solution will allow to simplify the design, reduce consumption, reduce size, improve reliability of the device and to simplify the process of transportation of materials in the development of mineral resources.

The invention is illustrated by drawings, where:

figure 1 shows a longitudinal section of the discharge station of the system of the pneumatic container transport,

figure 2 - view of the unloading station from above,

figure 3 - cross section a-a in figure 1,

figure 4 - cross section B-B in figure 1,

figure 5 - about the Aulnay incision loading station system pneumatic container transport,

figure 6 - view of a loading station at the top,

figure 7 - arrangement of the branches of the pipeline guide transport path.

Pneumatic container transport includes the boot 1 and the discharge 2 platform, cargo 3 blank 4 branches of the pipeline, forming a single closed guide transport path, filled with compressed air lock chamber 5 and the pneumatic pump 6. Guide transport path is made in the form of horizontal and inclined sections, and at the discharge site 2 cargo piping 3 is located above the blank line 4, and on the loading platform 1 below. The branches 3 and 4 of the transport path on both sides executed smoothly converging at one point with the formation of the coupling and provided with a by-pass valve 7 and the flaps 8, 9, 10 and 11. Moreover, the flaps 8 and 10 are installed at the beginning of the inclined guide sections of the transport path, and the valve 9 and 11 in the beginning of the idle and commercial branches. The bypass valve 7 located in front of the flaps 8 and 10. The boot 1 and the discharge 2 platform equipped with ejectors 12. Lock chamber 5 is located at the intersection of the truck 3 and idle 4 branches of the pipeline. The discharge space 2 is provided with tripper (Fig. not shown) and the receiving hopper 13 and the loading area 1 - hopper 14.

Device is istwo works as follows.

Containers pipelines are moved by compressed air supplied into the inner space of the sending transport path by using a pneumatic pump 6. Moving cargo piping 3, the loaded container is braked in front of the flap 8 by creating the air cushion. The air from the cushion through the bypass valve 7 flows into the idle branch 4 of the pipeline, pushing the container, moving on it. At the time of stop of the container valve 8 is opened, and it continues its motion scooter. After the container passes by the valve 8, it is closed for the next container. Moving the loaded container locatives to the discharge site 2 stops and unloaded by reversing tripper (Fig. not shown). Cargo is poured from the container into the hopper 13. After returning the container to its original position it is pushed out of a tripper with ejector 12 and continues to move the scooter on a sloping site at the junction of the cargo 3 blank 4 branches of the pipeline (see figure 1, 2). There the container is braked through the creation before him airbags. After stopping empty container it is due to the expansion of the compressed air inside the cushion begins to move in the opposite direction, moving at idle etvi 4 of the pipeline through its downward inclination (see figure 3 and figure 4). Figure 3 shows that the container is still in the cargo branch 3 of the pipeline, and 4 is already in the idle branch 4 of the pipeline. Moving on idle branch 4, the container passes through the valve 9, which is closed, and then in the pipeline serves the compressed air from pneumonias 6. Empty container moves along a no branch 4 of the pipeline to the boot area 1. Further movement of the container to the loading site 1 and then on cargo branch 3 of the pipeline occurs in a manner analogous to that described above (see figure 5, 6).

The branches 3 and 4 of the pipeline in the inventive device are arranged in such a way as to ensure the fullest use of the kinetic energy during transportation, which has loaded and empty containers, and the bypass valve 7 allows the compressed air to circulate in the system, thereby reducing the energy costs of its delivery. The connection of the branches 3 and 4 of the pipeline smoothly converging at one point, reduces the cost of materials and labor for construction of a section with a large radius of rotation containers.

In case of failure of the container, it can easily out smart transport path or enter a new container using the sluice chambers 5.

In addition, the use of the system pnevmaticheskogo the container transport in the development of mineral resources will help to minimize the damage impact on the environment. This is due to the fact that there is no damage to herbaceous and woody cover, there is no violation of the conditions of the local fauna, reduced the possibility of soil erosion, the formation of mudflows and landslides on developing the area as a transport path is located inside the array and virtually no surface damage.

The use of the proposed solution will allow for a comparison with the prototype to simplify the design, reduce energy and materials consumption, reduce size, improve reliability of the device and to simplify the process of transportation of materials in the development of mineral resources.
