Description

The utility model relates to the field of rolling production, for example, for the transverse transfer of long and sheet products between parallel live rolls at the finishing sites or in sheet rolling mills for encouraging the rolls before finishing rolling. Various types of devices are known for the lateral movement of a rental. The most widespread transmission devices with flexible stretching or supporting elements - ropes or chains moving the rental along stationary or lifting rails (Glazkov V.S. Continuous transportation mechanisms for rolling mills. M .: Metallurgy, 1979, p.178-210) .

A common drawback of flexible traction bodies is their hood and breaks, especially with a reverse mode of operation. Adjusting the tension and eliminating the cliffs are very time-consuming operations leading to long downtimes of the mill.

In addition, drive and idler sprockets and drums are installed outside the rental transfer zone, which increases its area and the length of the traction organs.

A device for transferring workpieces from a roller table to a roller table (RF Patent No. 2129928, M. cl. 21 V 39/00, publ. 05/10/99), consisting of two roller tables and a mechanism for the transverse movement of rolled products between roller tables, containing two manipulators installed on the outside of the roller tables, each of which consists of two rods with a rack-and-pinion drive for their horizontal movement, and a ruler connecting the outer ends of the rods. A disadvantage of the known device is that the rack drive rods are located outside the roller tables and occupy a significant area. To compensate for the deflection of the rods installed additional stationary support rollers along the entire length of their stroke. Another disadvantage of the known device is that the movement of the rolling is carried out with sliding, which causes wear and deformation of the rubbing surfaces.

The closest analogue of the claimed technical solution is a device for moving rental (RF Patent No. 45315, M. class. In 21 In 39/00, publ. 05/10/2005). The device consists of parallel live rolls and a rental transfer mechanism between them, containing rods with a rack-and-pinion drive of their horizontal movement located between the live rolls, and transporting rulers pairwise connecting the ends of the rods equipped with rollers mounted with the possibility of longitudinal movement in profile guides fixed

between the rollers of the roller tables along the entire length of the stroke of the rods. Between the live rolls are installed guides equipped with support rollers. The disadvantage of this device is that the movement of the rolled products, carried out by the rulers, is dragged with sliding on the rollers of the roller tables, which causes deformation and damage to the rubbing surfaces of both the rollers and the rolled products. Another disadvantage is the limited technological capabilities of the device due to the fact that the rulers move the rolled products in one direction from the extreme position relative to the roller table axis, that is, they cannot work reversely. After the transfer of rental from one roller table to another, the lines should be set to their original position, for which it is necessary to provide free space on the roller tables, which reduces the performance of the device. In addition, when the ruler crosses the roller table field, it is necessary to stop it in order to avoid the ruler colliding with the rolling stock.

The proposed utility model solves the problem of increasing the mobility and technological capabilities of the device, ensuring the reverse transfer of rolled products with laying in any position, as well as the free independent simultaneous movement of carts and rolled products along the rolling tables.

To achieve this goal, in a device for moving rolled products between parallel roller tables, containing a mechanism for transferring rolled products from one roller table to another, mounted with the possibility of longitudinal movement in profile guides fixed between adjacent rollers of the roller tables, a gear drive for moving, including a rotary shaft with gears, located between live rolls, the mechanism for transferring rental from one live roll to another includes trolleys with gear racks and track rollers, and the profile guides They are equipped with a lifting and lowering mechanism made in the form of parallel rows of rotary two-arm levers mounted under each profile guide, the upper arms of which are pivotally connected to it by axles, while the central rotary lever of each row on the rolling bearings is mounted on the rotary drive shaft, and on the axis connecting its upper shoulder with a profile guide, an intermediate gear wheel is installed with the possibility of free rotation, which interacts with the gear of the rotary drive shaft and gears wedge rail carts, and the lower ends of the two shoulders of the levers of each row are pivotally connected by rods with a common lever mechanism for their rotation, equipped with a hydraulic drive. In this case, support beams are installed between the rollers of the parallel roller tables.

Distinctive features of the proposed device for moving rolled products between parallel roller tables from the above known device,

the closest to the claimed are the supply of the device with a mechanism for raising and lowering the profile guides with trolleys and the implementation of the drive moving the carts rack and pinion.

Thanks to these features, the maximum mobility of the device is achieved and the technological capabilities of the device are increased. Moving the rental along the roller tables and the movement of the carts in the profile guides is carried out freely independently of each other. Transfer of rental trolleys is carried out smoothly without jamming and sliding in any direction.

The proposed device for moving rolled products between parallel roller tables is illustrated by the drawings shown in figures 1-5.

A device for moving rolled products between parallel live rolls contains live rolls 1, 2, a mechanism for transferring rolled products from one live roll to another, including trolleys 3 with toothed racks 4 and track rollers 5, mounted for longitudinal movement in profile lifting rails 6 fixed between adjacent rollers of the live rolls 1, 2 along the entire length of the trolleys 3, the gear drive 7 of their movement, including located between the parallel roller tables 1, 2, the rotary shaft 8 with gears 9, interacting with gear with rails 4 of trolleys 3, as well as a mechanism for raising and lowering the profile guides 6 with the trolleys 3, made in the form of parallel rows of rotary two-arm levers 10, 11 installed under the profile guides 6. The upper shoulders of the two-arm levers 10, 11 are pivotally connected to the profile guides 6 axes 12. Central rotary levers 10 of each row on rolling bearings 13 are mounted on a rotary shaft 8, and on the axes 12 connecting their upper shoulders with profile guides 6 are installed with the possibility of free rotation of the gap Meth toothed wheel 14, cooperating with gear 9 of the rotary shaft 8 and the toothed racks 4 and the carriages 3.

The lower shoulders of the two shoulders of the levers 10, 11 of each row are pivotally connected by rods 15 with a common lever mechanism 16 for turning them, equipped with a hydraulic drive 17. Between the rollers of the parallel roller tables 1, 2, removable support beams 18 are installed, designed for intermediate laying of rolled products in order to cool or delay it transmission. A gear drive 7 with a rotary shaft 8 is installed between the roller tables 1 and 2. The rods 15 of the lever mechanism 16 of the rotation of the levers only work in tension.

The operation of the device to move the rental between parallel roller tables is as follows. In the initial position, the profile guides 6 with trolleys 3 are lowered below the level of the rollers of the roller tables 1 and 2. (figure 2). In this case, the rolling stock and the carts 3 can freely move, respectively, but the rolling tables 1 and 2 and in the profile guides 6. The rolling stock arriving along one of the rolling tables to be transferred to the other rolling table stops in the zone of operation of the rolling transfer mechanism from one rolling table to another. At the same time, the carts 3 move along the lowered profile guides 6 and stop under hire. Carts 3 with profile guides 6 are raised to the upper position (Fig. 3), they are rolled and transferred for laying on a parallel roller table, or on support beams 18 installed between the roller tables 1 and 2. After stopping the cart 3 with profile guides in the required position 6 are lowered to the lower position and returned to the starting position for receiving the next ingot, or remain in the lowered position under the rolled steel for its further transfer.

Due to the possibility of raising and lowering the trolleys with profile guides, the maximum mobility of the device, the reverse movement of the rental, its removal and installation in any position are achieved. When the trolleys move in the lowered position, the roller conveyor fields remain free for transportation of rolled metal in any direction.

To move the rental between parallel rolling tables, it is enough to use only one mechanism for transferring rental from one live table to another, while in the device for moving rental, which is the prototype, it is necessary to install two mechanisms for transferring rental, since rods equipped with rulers can only transport rolled products in one direction. In addition, when the rods return to their original position, the rulers cross the rolling table, which prevents the rental from moving along it.
