Description

The invention relates to metallurgical equipment, and more specifically to devices for the transfer of rolled metal products, in particular to rack coolers for cooling rolled products,

A device for lateral movement of products is known, in which walking beams (slats) are mounted on diametrically located cranks of crankshafts and move along a circular path in the direction of movement of the heated metal.

The disadvantages of this device are that the metal to be rolled metal (cage) is lifted by one group of rails and transferred to the nests of another group of rails with a certain amount of power (energy) to lift the entire cage of the metal being heated, the metal rolling does not roll when shifting rotation due to the shaft eccentricity difference), which leads to the deformation of the metal during heating or cooling.

The closest in technical essence is a device containing fixed beams with a smooth outer surface and parallel moving beams rolling cold rolled steel along fixed beams. The movable beams have teeth and are divided into two groups, with the teeth of the second group of beams shifted by half a step with respect to the teeth of the beams of the first group. Moving beams make a swinging movement from the drive. When the beams of one group are in the upper position, the beams of the second group are in the lower position so that their teeth descend below the level of the fixed beams.

A disadvantage of the known device is that the swinging movement of the movable beams predetermines the presence of a greater number of hinged connections for the installation and drive of the movable

beams, which dramatically reduces the reliability and durability of the refrigerator due to wear of the hinge joints exposed to temperature, scale, and other environmental factors, as well as the cantilever arrangement of the hinge pins. In addition, when rolling metal on the horizontal surface of smooth beams, the possibility of spontaneous rolling of rolling and its falling onto the top of the tooth of the rising rail or even in another stream, which leads to disruption of the device and its stop, is not excluded.

The aim of the invention is to increase the reliability of the device.

In the device for the transverse movement of long-rolled steel, containing fixed beams with a smooth rolling surface, parallel upper and lower racks with shaped teeth, parallel to them, the drive of the alternate raising-lowering of the rails, beams and gear racks are set at an angle to the horizon of 3 -5 °, and with the arrangement of the teeth of the upper and lower rails one below the other, and the drive is made in the form of eccentric shafts with equal eccentricities, rotated 180 °.

Improving the reliability of the device is achieved by combining the use of fixed beams and gear racks installed at an angle a equal to 3-5 ° to the horizon and a movement drive, as well as eliminating the rocking movement of the movable rails and the associated large number of hinged joints. fastenings of laths and their connection with the driving mechanism.

The elimination of these nodes and connections greatly simplifies the transfer device. During the rotation of the eccentric shaft, the movable gear racks move along a circular path and with their teeth roll metal rolling along smooth fixed beams. For a uniform metal grip, eccentric shafts are made with equal eccentricities. Due to the fact that the fixed beams and movable gear racks are installed at an angle of 3-5 ° to the horizon, the rolled steel only concerns the pushing sides of the teeth of the rails, which eliminates its spontaneous rolling and, consequently, rolling into the next stream and malfunctioning of the device.

Figure 1 shows the device, a general view; figure 2 - view And figure 1.

The device for transverse displacement of long-length steel consists of fixed beams 1 with a smooth surface for rolling, mounted parallel to their upper and lower gear racks 2 with profiled teeth, to drive alternately lifting and lowering the rails. The drive is made in the form of eccentric shafts 3 with equal eccentricities,

rotated 180 °

The rotation of the eccentric shafts 3 is produced from the electric motor 4 through the gearboxes 5 and 6, the fixed beams 1 and the moving upper and lower gear racks 2 are set at an angle a equal to 3-5 ° to the horizon. The teeth of the upper and lower rails are located one below the other.

The device works as follows.

The metal (tube, circle) enters the fixed beams 1. Gear racks 2, moving along a circular path, with the help of their teeth, roll the metal alternately along the smooth surface of the fixed beams. Circular motion to the rails is communicated from the electric motor through gears 5 and 6 and eccentric shafts 3.

Thanks to the installation of beams and slats under

An angle of 3-5 ° and the rolled metal are constantly pressed against the pushing side of the tooth of the slats, which prevents its spontaneous rolling and, consequently, the overlap of the metal rolling along

teeth m disrupting the device.

With a smaller angle of inclination, the inertial forces during rolling of the metal rolling exceed the lifting force, so the metal rolling can

roll spontaneously, i.e. the effectiveness of such an angle is lost. At a larger angle, the drive power of the movement of the toothed racks increases unnecessarily.

The proposed device, in comparison with the known ones, makes it possible to increase the reliability of its operation by eliminating the spontaneous movement of metal rolling in a stream of gear racks, and consequently, by jumping over a long metal rolling to an adjacent stream and disrupting the operation of the device.
