Description

one

The invention relates to devices for the manufacture of asbestos-cement pipes and is a further development of the invention according to the author. Sat No. 142189.

Conveyors are known for holding and transporting raw asbestos-cement and similar pipes during their hardening, containing a chain roller conveyor enclosed in a heat-insulated gallery with moving and rotating rollers. The upper branch of the chain of this conveyor, bearing on itself the asbestos-cement pipes, is supported by a second chain conveyor installed inside the first. The adjustable speed of rotation of the rollers of the main conveyor, and hence of asbestos-cement pipes, is ensured by the adjustable speed of movement of the internal conveyor chain. However, the known conveyors are intended only for pipes with a constant diameter along the entire length and cannot be used for pipes with sockets that on such conveyors are deformed due to variable diameters along the length of the pipes and, accordingly, different peripheral speeds on the straight and shaped sections during their rotation.

The purpose of the invention is the possibility of transporting pipes with sockets.

For this purpose, on the axes of the main rollers, in the places of their contact with the sockets of pipes, additional rollers are freely rotated.

FIG. 1 schematically shows the proposed conveyor, general view; in fig. 2 - pipes laid on the conveyor; in fig. 3 - roller carrying pipe; in fig. 4 - a pipe with two sockets, laid on rollers; in fig. 5 - two single-bend pipes laid on rollers (or one pipe with shaped widening in its middle part).

The conveyor has a closed thermally insulated gallery 1, inside which a chain roller 2 and a chain track 3 conveyors are installed, having independent drives 4 and 5. Conveyor 3 is installed inside conveyor 2, with the upper (working) branch of conveyor 2 supported by tracks 6 of conveyor 3. Tracks are equipped friction linings. On the axles of the main rollers 7, mounted on the chain 8 of the trollseur 2, there are freely rotating additional rollers 9. At the entrance to the bridge there is a ramp 10, and at the exit is a ramp 11. In gallery 1 there are devices 12 and 13 for supplying technological steam and water to the collectors 14 to create an air curtain that retains the necessary temperature and humidity inside the gallery.

Asbestos cement pipe 15 with a bell

(or another shaped asbestos-cement pipe) ramp 10 rolls onto conveyor 2 and is located simultaneously on two main rollers 7. At the same time, the bell-shaped part of pipe 15 is on two additional rollers 9. When actuating the drive 4, conveyor 2 moves rollers 7, which, resting the tracks 6 are rotated and the pipe 15 is rotated. The speed and direction of its rotation can be adjusted by changing the speed of the tracks of the conveyor 3. The additional roller 9 in contact with the socket of the pipe 15 rotates with Uneven speed of the socket, without causing deformation of the pipe.

The unloading of the pipes 15 from the conveyor 2 is performed by freely rolling them along the ramp 11, after which they are sent for further processing.

Subject invention

A conveyor for holding and transporting raw asbestos-cement and similar pipes during their hardening according to ed. St. No. 142189, characterized in that, in order to enable the transportation of pipes with sockets, freely rotating additional ones are installed on the axes of the main rollers at the points of their contact with the sockets.
