Abstract

The invention relates to industrial transport, in particular to roller-belt support conveyor belts and reduces the duration of repair downtime by providing; the possibility of replacing outdated rollers without stopping the conveyor; the Roller support is equipped with U-shaped sumps; cotton wool, each of which is connected to the supporting elements by a hinge at its ends. The supporting elements are made in the form of brackets 1 and 2 with horizontal axes 13. The grip bar has a shank located on the axis of symmetry. In this case, each bracket (C) 3j, guided to the supporting elements, is provided with a hole 15 for accommodating a hook. At the other end of C 3, a through groove 16 is provided to move the horizontal axis AND of the support element therein. The SOC may be provided with a shaped protrusion 17 for interacting with the gripper. With the release of C 3 by means of gripping, the rollers 6 and 7 are released from contact with the tape 5, Installed: the rollers with the new rollers are produced by a lifting crosshead clinging to the hole 15. At the same time, C 3 is lifted by the hole 15 until until it becomes possible; fixing the grip to the end with the groove 16.

Description

The invention relates to industrial transport, in particular, to roller conveyor belts.

The purpose of the invention is to reduce the duration of repair downtime by allowing the replacement of outdated rollers without stopping the conveyor.

Fig. 1 shows the roller conveyor of a belt conveyor, with the left part being in the working position and right is omitted, in fig 2, the view along

arrow A in FIG. 1, FIG. 3 - view along arrow B in FIG. 1,

The roller conveyor belt includes supporting elements 1,2, brackets 3, hung on supporting elements 1,2, hooks k in the form of hooks, hung on brackets 3, and supporting tapes 5 rollers 6, 7,

The rollers 6 are connected by hinges 8 with the axis of the roller 7, and the hinges 9 with hooks 4.

The roller conveyor is equipped with U-shaped grippers 10, each of which is ball-linked to support elements 1 with its ends, its cross member has tails of $ 11 located on the axis of symmetry of the gripper 10 "

The supporting elements 1, 2 are embodied in the form of brackets 12 with horizontal axes 13, 14. By axis 13, bracket 12 is connected to the ends of the U-shaped grip 10, and on axis 14 a bracket 3 is hung.

Each bracket 3 at one end is made with a hole 15 for accommodating the hook 4, and at the other end with a through groove 16 for moving the horizontal axis 14 of the support in it.

Items 1, 2, Brackets 3 also have

at one end of the figure projection 17.

 Roller belt conveyor with its supporting elements 1, 2 mounted on metal 18,

Powered roller support as follows.

In the working position, the tape 5 is in contact with the rollers 6, 7, the hooks 4 inserted into the holes 15 are hung on the brackets 3, which through the axis 14, are placed in the slots 16 of the brackets

1, 2, are supported on metal structures 18, with the brackets 3 being kept from overturning by the U-shaped grippers 10, and the figured protrusions 17 prevent the movement of the brackets 3 to the conveyor axis.

In the working position, the load from the mass of the roller, the belt 5 and the transported material is transmitted through the hooks 4 to the brackets 3. The direction of the force coincides with the axis of the hook 4, This force is angled to the horizon and can be decomposed into components, horizontal and vertical ( down), the vertical component attempts to rotate the bracket 3 around the horizontal axis 14 and thereby presses

in conjunction with friction forces, the U-shaped gripper 10 does not spontaneously jump off the cramp 3. , Thus formed

moving the bracket 3 to the axis of the conveyor. If it is necessary to replace an outdated roller by the shank 11, turn the U-shaped grip 10 around the horizontal axis 13 from the axis of the conveyor. At the same time, the U-shaped grip slides along the shaped ledge 17 | slightly lower the bracket 3, and slide off of it. For strength of the rolls of the rollers 6, 7, the brackets are rotated around the horizontal axes;

Instead of them, the same set with new rollers is introduced under belt 5,

Hang hooks 4 on brackets 3 (inserted into holes 15) "Hooking the brackets 3 behind the holes 15, for example, with a crane through the yoke (not shown), lift the roller holder up to 0 and hold the ends of the brackets 3 into the metalwork 18 ,,

Lifting roller supports is as follows. A traverse is lowered from above, the ends of which can be 5, for example, in the form of horizontal axes inserted into an opening.
