Description

This invention relates to conveyor transport used in mining conditions.

The aim of the invention is to reduce the labor intensity in moving the needles of the conveyor.

FIG. 1 shows an angled telescopic belt conveyor (both parts of the conveyor are conventionally depicted in the same plane), general view; in fig. 2 - view of the platform with an installed corner station, an end section and a shifter; in fig. 3 - a movable platform (the assemblies of the conveyor installed on it are conventionally not shown), a plan view; in fig. 4 shows section A-A in FIG. 3; in fig. 5 is a diagram corresponding to the elongation of the conveyor; in fig. 6 is a diagram corresponding to a reduction in the tail section of the conveyor; in fig. 7 is a diagram corresponding to the arrival of the end section on the platform; in fig. 8 is a diagram corresponding to the platform movement to the next installation site.

The angled telescopic belt conveyor consists of a driving station 1, a telescopic section 2, standing with 3 heads with upper 4 and lower 5 roller-bearings, corner station 6 with upper 7 and lower 8 swivel points mounted on it, as well as upper 9 and lower 10 deflecting drums, staging the tail section with the upper 12 and lower 13 roller supports, the end section 14 with the drum 15, which can be moved along the soil of the mine, for example, by installing it on skis 16. All conveyor nodes are interconnected by a tape 17, the envelopeor moving through them. To move the end section 14, a mover, such as a combine 18, is interconnected by a link 19.

For shifting the tail part of the conveyor to another installation site, a supporting-mobile mechanism 20 is used, consisting of an expansion-strutting mechanism 21 and a supporting device made in a platform bidet 22, at one end 23 of which the corner station 6 is fixed, and at the other end 24 is located platform 25 with exit 26.

The platform is mounted on the left 27 and right 28 supports of the spacer-walking mechanism, and with the left supports it has a rigid connection 29, and on the right it is installed freely without fixing. In addition, hydraulic legs 30, left 31 and right 32 beams, and shifting jacks 33 are part of an expansion mechanism.

The shifter jacks are mounted on the right bearings 28 and are connected to the left bearings 27 by means of brackets 34. To maintain a given direction when shifting the platform, it is equipped with

guides 35. In addition, the platform is additionally mounted on skis 36.

There are other options for connecting the platform with the nodes of the spacer-walking mechanism.

In addition, the longitudinal axis of the platform is located at an angle to the direction of its movement, which coincides with the longitudinal axis of the head part of the conveyor, which is equal to the angle of rotation of the conveyor a.

An example of a specific installation of the conveyor.

The head part of the conveyor is mounted on the conveyor drift 37, the tail part is in the bottom 38. A lower arm 39 is provided for the installation of the support-movable mechanism. To protect the conveyor from blockage, individual supports 40, landing stands 41, bonfires 42 are used.

When cleaning works are carried out together with the harvester 18 (Fig. 5), the end section 14 moves towards the face, by loosening the tape 17 on the telescopic section 2. As the length of the tail section of the conveyor increases, the stand becomes 11 with the roller supports 12 and 13.

Moving the tail of the angled telescopic belt conveyor means that during the return stroke of the harvester 18, the stand becomes dismantled. And the tail of the conveyor with the roller supports 12, 13, the tape 17 is pulled by the telescopic section 2, while the end section 14 moves towards the corner station 6 ( Fig. 6).

After the end section 14 reaches the support-mobile mechanism 20, it skips 16 on the ramp 26 to platform 22. Following the end section, the mobile unit 18 pushes it onto the platform, after which they are installed on platform 25 of platform 22, moreover, the order of their mutual arrangement and orientation relative to the longitudinal axis of the head part of the conveyor remains unchanged (Fig. 7).

By becoming 3 the head of the conveyor is reduced by an amount equal to the width of the gate of the combine. The hydraulics 30 of the left supports 27 of the support-movable mechanism 20 are turned on to lower, thereby removing the left beams 31 from the thrust. The advancing jacks 33 turn on extending (Figs. 3, 4) and move the left supports 27 with the hydres 30 and left beams 31. In As a result, the platform 22 mounted on the left support and connected with it by links 29 and the corner station 6 installed on it, the end section 14 and the combine 18 on the value of the progress of the advancing jack.

Then, the hydraulics 30 of the left-side supports 27 bulge the left-side beams 31 into the roof of the mine, similar to the hydraulics of the right-side supports 28 turn on lowering, thereby removing the right-side beams 32, after

As the jacks 33 shifters pull right supports 28 with hydraulic legs 30 and right beams 32. Hydraulic legs of the right supports 28 burst right beams 32 into the roof of the road, the platform shifting cycle is completed.

The number of cycles depends on the width of the approach of the combine.

The tape 17 is weakened when the platform is moved, and therefore is periodically pulled up by the telescopic section 2. After

the platform 22 is mounted at the beginning of the next excavation strip (Fig. 8).

The design of the support-mobile mechanism allows the platform to maneuver in order to maintain a given direction mobile by working not all of the advancement jacks at once, but only part of them, for example, not two (Fig. 3), but only one.
