Abstract
The utility model relates to a combination elastic element of a ladle slide gate mechanism, which comprises a cylindrical helical spring and a gas spring; the outer diameter of the gas spring is slightly smaller than the diameter of the inner cylindrical hole of the cylindrical helical spring, and the free height of the gas spring is ideal to that of the cylindrical helical spring; and the gas spring is installed inside the inner cylindrical hole of the cylindrical helical spring to assemble a combination elastic element. The combination elastic element is applied to the ladle slide gate mechanism. The combination elastic element is characterized in that when the temperature of the work environment of the ladle slide gate mechanism varies, the elastic force variation of the two springs is compensated with each other, so that the elastic force of the combination elastic element can maintain constant basically, thereby being an ideal elastic element for the ladle slide gate mechanism.
Description
Affiliated technical field
The utility model relates to the combined elastic element of a kind of steel ladle sliding water gap mechanism.Employed a kind of flexible member in the specifically a kind of steel mill steel ladle sliding water gap mechanism.
Background technology
At present, the employed steel ladle sliding water gap of most steel mills mechanism mainly is made up of parts such as base, upper slide brick, support, slide block, lower skateboard brick, the following mouth of a river, flexible members; Wherein flexible member is the significant components of steel ladle sliding water gap mechanism, and the plate surface pressure between upper and lower sliding plate brick produces reaction force by compression elastic element and sets up.Steel ladle sliding water gap mechanism works under the working environment that changes between normal temperature and the high temperature, so the elastic force size of flexible member and characteristic determine the size of plate surface pressure between upper and lower sliding plate brick and the size of plate surface pressure intensity of variation when operating ambient temperature changes.The flexible member that the steel ladle sliding water gap mechanism of present technology is adopted has two types basically, and one type is the flexible member that relies on the stressed generation strain generation of metal material elastic force, as cylindrically coiled spring, disk spring etc.; Another kind of type is the flexible member that relies on compression seal gas generation elastic force, as gas spring.The elastic force of these two types of flexible members is subjected to the influence of operating ambient temperature all bigger.Rely on the stressed generation strain of metal material to produce the flexible member of elastic force, the elastic force of flexible member will reduce when operating ambient temperature raises, and causes the plate surface pressure deficiency between upper and lower sliding plate brick, causes the bleed-out accident; And rely on compression seal gas to produce the flexible member of elastic force; the elastic force of flexible member will raise when operating ambient temperature raises; cause the plate surface pressure between upper and lower sliding plate brick to increase, the slide block of steel ladle sliding water gap mechanism can not normally be slided and cause the disconnected accident of watering.
Summary of the invention
In order to overcome the deficiency that prior art exists; the utility model provides the combined elastic element of a kind of steel ladle sliding water gap mechanism; when operating ambient temperature changes; elastic force substantially constant during this combined elastic element work; can make between the plate face of upper and lower sliding plate brick and set up substantially invariable plate surface pressure, avoid force variation because of flexible member to cause the slide block of steel ladle sliding water gap mechanism normally not slide and cause disconnected generation of watering accident and bleed-out accident.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises cylindrically coiled spring and gas spring; The external diameter of gas spring is slightly less than cylindrical hole diameter in the cylindrically coiled spring, and the free height of gas spring equates with the free height of cylindrically coiled spring; Gas spring packed into form the combined elastic element in the interior cylindrical hole of cylindrically coiled spring.Described combined elastic element application is in steel ladle sliding water gap mechanism.When steel ladle sliding water gap mechanism is in running order, while compressed-gas springs and cylindrically coiled spring, the upper and lower sliding plate brick of elastic compression of two types of springs of dependence makes and sets up the plate surface pressure between upper and lower sliding plate brick.When the operating ambient temperature of steel ladle sliding water gap mechanism raise, the elastic force of cylindrically coiled spring can reduce, and the elastic force of gas spring can raise; When the operating ambient temperature of steel ladle sliding water gap mechanism reduced, the elastic force of cylindrically coiled spring can go up, and the elastic force of gas spring can reduce; This shows that when the operating ambient temperature of steel ladle sliding water gap mechanism changed, the force variation of two types of springs compensated mutually, the elastic force of described combined elastic element can keep substantially constant.
The beneficial effects of the utility model are: when the operating ambient temperature of steel ladle sliding water gap mechanism changed, the force variation of combined elastic element was very little, so pressure can keep substantially constant between the plate between upper and lower sliding plate brick.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a cutaway view of the present utility model.
1. cylindrically coiled springs, 2. gas spring among the figure.
The specific embodiment
In the accompanying drawings, the external diameter of gas spring (2) is slightly less than the interior cylindrical hole diameter of cylindrically coiled spring (1), and the free height of gas spring (2) equates with the free height of cylindrically coiled spring (1); Gas spring (2) packed into form the combined elastic element in the interior cylindrical hole of cylindrically coiled spring (1).The flexible member of combination is applied in the steel ladle sliding water gap mechanism.
