Description

I

The invention relates to conveyor engineering, in particular to roller supports used primarily in the loading units of belt conveyors.

Known and widely distributed grooved rolikoopori with conventional or shock-absorbing rollers rigidly mounted on a common support frame.

Also known is the construction of a roller bearing comprising a support beam, a middle roller and laterally movable in a vertical plane.

However, in the well-known rigid roller supports, especially when using them in the form of batteries at the loading points, it is difficult to replace broken rollers due to the small pitch between the roller supports and limited access to the rollers. Replacing the rollers in such places causes significant loss of time, since it is necessary to loosen the belt tension, remove the sealing strips and guide boards of the hopper, dismantle adjacent rollers, replace the faulty roller and reinstall the equipment in reverse order.

The purpose of the invention is to simplify the replacement of the roller bearings.

To do this, in the proposed roller-resistor, the roller is mounted on a frame movably mounted along the support beam and hingedly connected to the side rollers.

FIG. 1 shows the position of the proposed roller support at the place of loading; on

FIG. 2 - rollers, general view.

The roller support is installed in place of roller batteries I of loading devices, usually including a receiving funnel 2, to the guide boards 3 of which sealing rubber strips 4 are attached. A supporting frame 7 with the middle roller 8 is supported on the carrier beam 5 of the roller supports 6 The supporting elements are made, for example, in the form

lateral rollers 9 with girth frames 10, are connected on the inside by flap 11 with frame 7, and on the outside are supported through pins 12 on folding H-shaped strut 13. Through axis 14 these strut

they are connected to beam 5, and they are provided with brackets 15 to impart stability to the whole roller supports.

Servicing rollers in the event of failure of the rollers produced as follows

in a way.

When the side roller is replaced, the axis 14 is taken out, the column 13 is retracted to the side and the frame 10 is lowered by the handle 16 together with the roller 9 into a horizontal position. Movie, getting

thus the freedom to move up

it is easily removed from the grooves of the frame and replaced with a working one, after which the frame with the roller is re-installed in an inclined position and pressed against the belt 17.

If it is necessary to replace the middle roller, the axles 14 on both sides of the rollers are removed and, by lowering the side rollers 9 together with their frames 10 in a horizontal position, guide the pillars 13 sideways. In such a position, having pulled the handle 16 in the desired direction, the frame 7 with the middle roller 8, due to the existing rollers 6, easily moves to the edge of the carrier beam 5. After replacing the defective

The roller of the roller carrier returns to its original position.

Subject invention

A roller bearing comprising a beam, an intermediate roller, laterally movable lateral rollers, characterized in that, in order to simplify the replacement of the roller supports, the middle roller is fixed on a frame movably mounted along the support beam and hinged to the side rollers.
