Abstract

SUMMARY OF THE INVENTION: a conveyor system includes several parallel chain conveyors with load-bearing elements. Ensuring reliable transportation with simultaneous rotation of pipes with an inner coating in the form of a glass-enamel slip and reduced energy intensity is achieved due to the fact that the system is equipped with a supporting surface in the form of guides located between conveyors, and each load-bearing element is made in the form of a pusher fixed to the track with a roller at the end located above the abutment surface between adjacent rails. 2 ill. ate with

Description

The invention relates to transport engineering, and in particular to chain conveyors for transporting long cylindrical products; slabs, logs, but mainly pipes coated internally with a slip during the manufacture of glass-enamel pipes.

Devices are known for transporting long cylindrical products, for example, for moving large slabs, consisting of rollers connected in parallel chains, rolling along a channel path and driven by a traction chain.

 Such devices cannot ensure the continuous rotation of pipes coated inside with a wet slip and their movement without shocks and collisions, which is necessary for the transport of pipes coated with slip.,

A transverse conveyor used on a timber rafting was selected as a prototype. This device comprises several parallel chain conveyors on which a hook is attached over a certain distance to grasp the logs. Although the number of nodes identical to / the halls of the conveyor system is small, the transverse cc n-fan has the same disadvantages as the analogue described above.

The aim of the invention is to ensure reliable transportation while rotating the pipes with the inner coating. In the form of glass-enamel slip and reducing energy consumption.

The goal is achieved in that the technical solution for the movement of pipes with an internal slip coating uses the geometric shape of the pipes, allowing them to roll, so the proposed conveyor system consists of several parallel guides with a supporting surface located with a slight inclination towards the movement (4-6 ° ), between which there are traction chain conveyors in such a way that their upper branch is located below the supporting plane of the guides, in addition, their drive sprockets are reinforced rigidly around I eat a shaft that provides the synchronous motions of circuit elements; moreover, the tracks, the swivel connection of which form a conveyor chain with each other, have a design that allows them to be supported by load-bearing elements - pushers made with a roller at the end.

Distinctive features of the invention in comparison with the prototype are the following: the presence of a support surface in the form of rails located between conveyors, the execution of a load-bearing element in the form of a pusher fixed to the track chain with a roller at the end, the location of the pusher rollers above the support surface between adjacent rails who are. .

In FIG. 1 shows a device, a top view; in FIG. 2 is the same, partial sectional side view.

The installation consists of a series of parallel guides 1, the upper plane of which is elevated above floor level 2 (in the case where the pipes are supposed to move in one direction, then guides 1 are given a small length of 6 °), between them in a trench x 3 and , with pins 4, parallel to the guide rails 1 are traction chain conveyors 5 having slave

faceted sprockets 6 and leading faceted sprockets 7, rigidly mounted on a common shaft 8, which can rotate in the bearings of the uprights 9, obtaining

5 movement from the drive 10; the chain conveyor 5 consists of articulated tracks 11, on which load-bearing elements are mounted in the form of pushers 12 with a roller 13 at the end. For example, the position of only one transported pipe 14 is shown.

The number of guides 1 is determined by the length of the pipes 14, their diameter, i.e. lateral stiffness, and thrust conveyors

5 5 there can only be two. As seen in FIG. 2, the tracks 11 of the conveyors 5 are located below the upper plane of the rails 1, and the rollers 13 are higher.

The movement of pipes by the conveyor system is as follows.

Pipes 14 are stacked one by one perpendicular to the guide 1 between the rollers 13 of the moving conveyors 5, the movement of which is carried out by a drive 10 by 5 by rotating the shaft 8 in the bearings of the uprights 9 and faceted sprockets 7 rigidly fixed on the shaft 8. vehicle along the bearing surface of the rails 1,

0 pushed by the pushers 12 with rollers 13. The roller 13 does not hinder, but facilitates the rotation of the pipes 14. This is very important if the pipes move, the coating inside with a wet slip. At the end of the pipe path 14

5 are either overloaded with a forklift truck or delivered to a roller table.

Using this conveyor system will reduce energy costs to a minimum, because the movement of pipes

0 perhaps by scooter, here the role of conveyors is reduced only to ordering the movement, maintaining a distance and preventing collisions of pipes, preserving the rotation of the pipes around its axis.
