Description

FIELD OF THE INVENTION This invention relates to hoisting and conveying machinery, in particular to belt conveyors that steeply and horizontally transport sticky bulk material with large pieces.

The aim of the invention is to increase the operational reliability and productivity of the conveyor by improving the discharge conditions of the conveyor belt.

Figure 1 shows a General view of a steeply inclined belt conveyor, side view; in Fig.2 - part of the load-bearing branch of the conveyor in the zone of its rotation by 90 °: in Fig.Z - section AA in Fig.1: in Fig.4-7 - respectively, sections B-B. C-C. DD and EE in figure 2.

The steeply inclined belt conveyor consists of a conveyor stand 1. of traction units in the form of packages of 2 ropes, cross members 3 attached to them, drive 5 and tension 4 drums, load-carrying belts

6 and 22, which are attached at the outer edges by hinges 8 to the individual ropes of the shopping bags 2. Traverses 9 are attached by clamps 10 to the same ropes of the shopping bags 2. The cross members 3 have wheels 11 at their ends, which are supported by the load guides 12 and empty parts of the conveyor stand. Both guides 12 in the unloading zone of the lower load-bearing branch of the tape are bent along spatial arcs of opposite directions, ensuring that the tapes 6 and 22 rotate 90 ° relative to the longitudinal axis of symmetry. Additional support wheels 14 are fastened to the cross members 3 by means of brackets 13 so that their axes are perpendicular to the axis of the cross member 3, supported by additional bending guides 15, further facilitating the rotation of the tapes 6 and 22 by 90 ° (to their vertical position) in the zone unloading of the transported material 16 and also carrying out supporting-bearing functions.

the bending guides 15 as well as the guides 12 are curved along spatial arcs of opposite directions. On the working side of the tape web there are flexible partitions 19. fastened in the middle part and cross-members 3 by girths 20, and on the sides are attached to the pull ropes of the bags by 2 clips.

The towing bodies 2 can be made of cable packages (as shown), of chain packages or of combinations of chains with cables to eliminate the harmful effects on the operation of the cable draw conveyor during operation and to improve the engagement conditions on the drive drum.

If necessary, the functions of the load-bearing web can be performed by one belt. To do this, a margin of length is provided on the cross members or corresponding grooves (not shown) are cut out in the tapes to ensure that the tape is straightened when moving from the grooved working form to the straight upper idler.

The conveyor works as follows.

When the drum 4 is rotated, together with the packages of pull ropes 2, the entire closed conveyor belt is driven. After bending from top to bottom of the tension drum 5, the wheels 1 of the cross members 3 are mounted on the guides 12 of the cargo part of the conveyor stand. In this case, the belts 6 and 22, under the action of centrifugal force and their own weight, are laid on the traverses 9, forming a chute. Bulk cargo to the moving working bed comes from the hopper-feeder 17. In the process of loading the cross-bar 3, they play the role of grate-bars, partially damping the blows of large pieces when dumping them into the load-carrying trough. The shock-absorbing device 18 at the loading point also protects the belts b and 22. The crosshead 9 from the appearance of residual deformations in them, taking in the energy of large pieces. During further steeply inclined transportation, the large pieces abut against the cross members 3, keeping small fractions of the load from slipping. In the case of transporting only small bulk cargo from slipping it along the belts 6 and 22, flexible partitions 19 are held.

When the working branch with the load enters the unloading section, the guides 12, bent along the spatial arcs, act through the wheels 11 on the crossbars 3. raise one edge of the tape and lower the other edge, turning it 90 ° relative to the longitudinal axis of symmetry, both edges are evenly stretched without causing unbalanced stretching of the tape. In this case, the weight of the rotated part of the load-bearing branch of the tape begins to be perceived by additional bending

guides 15, on which are supported

additional wheels 14, secured to

cross members 3 so that their longitudinal axis

perpendicular to its longitudinal axis.

When the working branch of the tape

(already without load) from the curved part of the guides 12 and the additional bending guides 15 of the wheel 13 and the additional support wheels 14, interacting with the guides, unfold the tape 6 and 22

to the initial horizontal position, which is maintained by moving the wheels 11 along the guides 12 of the cargo and empty parts of the conveyor stand. 4 tapes are suitable for the driving drum

horizontal position.

In the process of moving the conveyor belt from the bottom up around the drum 4, the grooves of the belts 6 and 22 are straightened to a straight profile, transferring it and

laying on cross members 3 due to its own gravity and tension. At the same time flexible partitions. 19 are folded under the belts 6 and, 22 the girths 20 hold them from excessive sagging towards the load branch

clamps 21.

This technical solution of the unloading device to the drive drum provides free unloading of cargo from the grooved space of the load-carrying

tapes in the unloading zone due to its rotation to a vertical position. The tape in the process of such a turn has the ability to uniformly deform along both of its edges without warping and uneven wear and the ability to straighten its grooved shape to a straight profile.

Forumula and Steep inclined belt conveyor,

including a stand with main guides, a load-carrying tape placed on a traverse with running wheels mounted on the main guides, characterized in that, in order to expand the Conveyor Functionality, each traverse at the ends is equipped with additional double-rib wheels, and on the stand in additional rails fixed perpendicular to the main rails are fixed at the unloading site, while the main additional rails at the unloading site are bent in a plane perpendicular to , the longitudinal axis of the conveyor with the possibility of turning the traverse at an angle of 90 °.
