Description
Technical Field
The utility model relates to the technical field of lifting appliances, in particular to a special lifting appliance for a tundish current stabilizer.
Background
With the rapid development of the continuous casting tundish metallurgical process, the tundish is not a pure molten steel receiving container in a continuous casting system and is changed into a refining device with multiple refining functions; the tundish is long in service life and good in stability, and the use safety is very important. The current stabilizer is used as an important component of a using link of the tundish, prevents inclusion from being involved when molten steel flows out, changes a flowing route of the molten steel, promotes the inclusion to float upwards, and improves the quality of a casting blank; therefore, the current stabilizer directly influences the service life and the use safety of the tundish. The current stabilizer is generally in a hoisting mode due to large volume and heavy self weight in the moving and installing process, the whole current stabilizer is of a barrel-shaped structure with an inward edge at the mouth part, the current stabilizer is difficult to hoist in a binding mode, and the current stabilizer is easy to fall off in the moving process even if the current stabilizer is successfully bound, so that potential safety hazards are formed, and therefore, the special lifting appliance is imperatively designed.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide the special lifting appliance for the tundish current stabilizer, which is designed for reducing the potential safety hazard and improving the production efficiency.
In order to achieve the purpose, the utility model adopts the following technical scheme: a special spreader for a tundish current regulator comprising: rings, rings below be equipped with vertical center pin, center pin upper portion and rings are solid as an organic whole, the center pin bottom is equipped with circular fixed plate, fixed plate surface centre of a circle and center pin bottom fixed connection, be equipped with four screw through-holes at fixed plate surface equipartition, every screw through-hole correspondence is provided with spacing bolt, spacing bolt lower extreme is connected with horizontal bracing piece respectively after passing the screw through-hole, the bracing piece be the bar post of equal length, its one end is equipped with screw through-hole and spacing bolt threaded connection, its length of bracing piece is greater than the radius of current stabilizer oral area, bracing piece length is less than current stabilizer inner chamber radius.
The lower end of the limiting bolt penetrates through the threaded through hole formed in the fixing plate and the supporting rod and then is provided with a nut, so that the supporting rod is prevented from falling off.
The lifting ring, the central shaft, the fixing plate, the supporting rod and the limiting bolt are all made of steel and used for guaranteeing the strength of the lifting appliance.
The contact end of the supporting rod and the current stabilizer is provided with a rubber sleeve, so that the inner wall of the current stabilizer is prevented from being damaged in the hoisting process.
The utility model has the beneficial effects that: this hoist structure is simple manufacture, advantage such as use scheme under the condition of guaranteeing the security, reduces the safety risk of workman in operation by a wide margin, ensures the safety problem of current stabilizer at the handling in-process, and in the middle of the handling package current stabilizer, the current stabilizer atress is even, avoids appearing the emergence of the not hard up circumstances of droing, improves the transport efficiency of product, reduces the labour, avoids the safety risk in the production process.

In the figure: 1. rings, 2, a central shaft, 3, a fixing plate, 4, a supporting rod, 5 and a limiting bolt.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the drawings in the specification, and it should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, a special sling for a tundish current stabilizer includes: rings 1, rings 1 below be equipped with vertical center pin 2, 2 upper portions of center pin are as an organic whole with rings 1, 2 bottoms of center pin are equipped with circular shape fixed plate 3, 3 surperficial centre of a circle of fixed plate and 2 bottom fixed connection of center pin, be equipped with four screw through-holes at 3 surperficial equipartitions of fixed plate, every screw through-hole correspondence is provided with spacing bolt 5, is connected with horizontal bracing piece 4 respectively after 5 lower extremes of spacing bolt pass the screw through-hole, bracing piece 4 be the bar post of equal length, its one end is equipped with screw through-hole and 5 threaded connection of spacing bolt, its length of bracing piece 4 is greater than the radius of current stabilizer oral area, bracing piece 4 length is less than current stabilizer inner chamber radius. The lower end of the limiting bolt 5 penetrates through the threaded through hole formed in the fixing plate 3 and the supporting rod 4, and then a nut is arranged to prevent the supporting rod 4 from falling off. Rings 1, center pin 2, fixed plate 3, bracing piece 4 and spacing bolt 5 all use steel to be used for guaranteeing the intensity of hoist. The contact end of the support rod 4 and the current stabilizer is provided with a rubber sleeve, so that the inner wall of the current stabilizer is prevented from being damaged in the hoisting process.
When the utility model is used: firstly, the hanging ring 1 of the utility model is connected with the crane hook, then the hanger is downwards arranged in the inner cavity of the tundish current stabilizer, when the horizontal height of the hanger is lower than the mouth part of the tundish current stabilizer, the four support rods 4 below the fixed plate 3 are rotated to ensure that the four support rods 4 are in a cross shape by taking the circle center of the fixed plate 3 as the center, then the support rods 4 are fixed by the nuts below each limit bolt 5, because the tundish current stabilizer is integrally in a cylindrical structure with an inward edge at the mouth part, the diameter of the inner cavity of the current stabilizer is larger than that of the mouth part, because the length of the support rods 4 is smaller than that of the inner cavity of the current stabilizer, the length of the connection of the two support rods 4 on one straight line is smaller than that of the inner cavity of the current stabilizer, and because the length of the support rods 4 is larger than that of the mouth part of the current stabilizer, the connection length of the two support rods 4 on one straight line is larger than that of the mouth part of the current stabilizer, therefore, the cross-shaped support rod 4 can be clamped at the edge of the opening of the inner cavity of the current stabilizer, the central shaft 2 is also automatically positioned at the center of the current stabilizer under the action of the unfolded support rod 4, so that the current stabilizer is uniformly stressed during hoisting, then the hoisting work is carried out by using a crane, after the tundish current stabilizer is hoisted to a designated position, the limit of a nut below the limit bolt 5 on the support rod 4 is removed, the support rod 4 is furled, and the hoisting tool is taken out from the tundish current stabilizer to complete the hoisting work.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
The present invention is not described in detail in the prior art.
