SU1245510A1 - Double-hinged hauling chain of flight conveyer - Google Patents

Description

The invention relates to the coal industry, and more specifically to the design of the drag chains of scraper conveyors for use in loading machines and tunneling machines, as well as in mining production lines as devices for transporting rock mass.

The aim of the invention is to increase the operational reliability of the traction chain by eliminating the transmission of transverse forces of the engagement of the teeth of the driving star with internal links to the outer strips and scrapers and avoiding floating up and down in the groove of the conveyor.

FIG. 1 shows a double-hinged chain of a scraper conveyor, plan view; in fig. 2 - interaction of chain links with a star of the conveyor.

A double-hinged pull chain of a scraper conveyor consists of internal links i and 2 connected by axes 3 and 4 with external strips 5 and scrapers 6. Internal links I allow the chains to bend in a vertical plane, and internal links 2 made by hinges the lugs 7, 8 and connected by the axis 9, allow the bend chain to bend in both vertical and horizontal planes.

The internal links 1 and 2 at their end parts 10, which are in contact with the teeth 11 of the driving sprocket 12, are made with the teeth of the 11 driving sprocket 12

parallel protrusions 13 and 14, with the end parts 15 of the protrusions 14 directed towards the movement of the thrust chain, having a plust shape, and the gap between the protrusions 13 and 14 of the adjacent links 1 and 2 is selected from the condition of simultaneous contact with the front and side surfaces of the teeth and drive sprocket 12.

The double-hinged pull chain of the scraper conveyor is made of separate sections, each of which is closed with the adjacent one by means of a lock 16, followed by fixing with cotter pins 17.

The chain works as follows.

When the mining machine operates, the drive sprocket 12 of the conveyor, which interacts with the internal links 1 and 2, begins to move the haul chain with scrapers along its chute, transporting the rock mass to the mine delivery equipment. At the same time, the zoo0 11 of the drive sprocket 12, falling between the internal links 1 and 2, are covered by their protrusions 13 and 14, being in contact with them at the same time as the side and end: and the surfaces of the teeth, excluding the transmission of transverse engagement forces

5 teeth 1I drive sprocket on the outer strips 5 and scrapers 6 tons of the bend chain, warning of a violation of the attachment of their axes. And the implementation of the end parts of the 15 protrusions 14 in the form of a plump-shaped prevents the floating chain when moving

DUCH SHAIR TRACTION CHAIN OF SCRAPER CONVEYOR, including interconnected scraper axles, outer rails and inner links with end parts for interacting with the end surfaces of the teeth of the drive sprocket, characterized in that each end part of the inner link is made with two protrusions located in parallel with the possibility of coverage on the sides of the tooth of the drive sprocket, while the protrusions of one end part of each internal link is directed They are in the direction of movement of the traction chain, and the protrusions of its other end part are opposed to the movement of the traction chain, and the end parts of the protrusions directed towards the movement of the traction chain are plow-shaped.
