Abstract
The utility model relates to a kind of cold blast sliding valve transmission device.Fixed oil cylinder on cylinder bracket, the piston of oil cylinder is fixed with active tooth bar, initiatively tooth bar and cylinder bracket are slidably matched, the driving gear engaging with active tooth bar is fixed on one end of transmission shaft, the fixing driven gear of the other end of transmission shaft, the driven tooth bar and the cold wind valve body that engage with driven gear are slidably matched, one end of driven tooth bar is stretched into cold wind valve body and is fixed with the slide plate of controlling cold blast sliding valve switch, on fixing on the cold wind valve body at described driven tooth bar two ends, lower axle bed, on, lower shaft seat supports transmission shaft, and be rotatably assorted with it, fix reinforcing bracket near on the cold wind valve body of described driving gear, reinforcing bracket supporting shaft, and be rotatably assorted with it.It is simple in structure, and intensity is high, indeformable.
Description
Technical field
The utility model belongs to transmission device, particularly a kind of transmission device of open and close cold blast sliding valve.
Background technique
Cold blast sliding valve role in blast furnace is produced is that hot-blast furnace temperature burns set point of temperature value and in the time that blast furnace send hot blast, opens cold blast sliding valve cold wind and hot blast is delivered to from hot blast stove to blast furnace, just can not complete as cold blast sliding valve breaks down process from hot blast to blast furnace that send, thereby affect the normal production of blast furnace.Because existing cold blast sliding valve exists defect, the spacing of gearing shaft from bearing to gear is excessive, and the diameter of axle is less, in use occurs that transmission shaft bending deflection even jumps the phenomenon of tooth, makes normally open and close of cold blast sliding valve, affects blast furnace and produces.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of cold blast sliding valve transmission device, and it is simple in structure, and intensity is high, indeformable.
The technical scheme in the invention for solving the technical problem is: fixed oil cylinder on cylinder bracket, the piston of oil cylinder is fixed with active tooth bar, initiatively tooth bar and cylinder bracket are slidably matched, the driving gear engaging with active tooth bar is fixed on one end of transmission shaft, the fixing driven gear of the other end of transmission shaft, the driven tooth bar and the cold wind valve body that engage with driven gear are slidably matched, it is fixing with the slide plate (not shown in FIG.) of controlling cold blast sliding valve switch that cold wind valve body is stretched in one end of driven tooth bar, on fixing on the cold wind valve body at described driven tooth bar two ends, lower axle bed, on, lower shaft seat supports transmission shaft, and be rotatably assorted with it, fix reinforcing bracket near on the cold wind valve body of described driving gear, reinforcing bracket supporting shaft, and be rotatably assorted with it.
The utility model is simple in structure, and intensity is high, indeformable, long service life.
Brief description of the drawings
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model schematic diagram;
Fig. 2 is A-A cutaway view Amplified image in the utility model Fig. 1.
