Summary of the invention
The technical issues that need to address of the present invention provide a kind of molten steel component tester, it mainly is to solve the existing in prior technology analyzer can not arbitrarily adjust the position of detecting gun barrel, therefore the detection position is more inaccurate, the technical matters of the bigger grade of data deviation that detects.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
Molten steel component tester of the present invention, comprise frame, frame is provided with guide rail, it is characterized in that described guide rail vertically sets up, and is connected with lift cart on the guide rail, lift cart is connected with drive unit, be hinged with steelframe on the lift cart, steelframe is connected with the gearing that can make its swing, and the outer end of steelframe is connected with the detection gun barrel of vertically setting up, detection gun barrel inside is provided with decides the hydrogen rifle, decides the hydrogen rifle and moves cabinet by the hydrogen of deciding that the connection of gas cable can feed nitrogen.Guide rail can be made by channel-section steel, is connected with travelling block on the lift cart, and travelling block can slide up and down on channel-section steel.Under the drive of lift cart, steelframe also can move up and down, thereby feasible detection gun barrel can go deep in the molten steel or leave molten steel.Steelframe can carry out horizontal hunting under the transmission of gearing, the amplitude of swing generally can cover the area of whole molten steel about 60o.Fixed pulley can be set on the lift cart passes through the gas cable.
As preferably, described drive unit includes the chain that is connected with lift cart, and chain is connected with reductor by sprocket wheel, and reductor connects buncher by belt pulley.Sprocket wheel can be set to a plurality of, is convenient to lift cart and can carries out elevating movement under the pulling of chain.Buncher is an electromagnetic adjustable speed motor, and buncher drives chain movement by reductor.
As preferably, described gearing comprises the cylinder that is hinged on the lift cart, and lift cart is located at a side of steelframe, and the push rod of cylinder is hinged on the steelframe; Also be hinged with hydraulic cylinder on the lift cart, hydraulic cylinder is located at the opposite side of steelframe, and the push rod of hydraulic cylinder is hinged on the steelframe.Cylinder, the hydraulic cylinder of steelframe both sides are worked respectively, can drive steelframe and swing in certain amplitude.
As preferably, describedly decide the moving cabinet of hydrogen and be connected with by cable and decide hydrogen computer instrument.Decide hydrogen computer instrument and can control and decide the moving cabinet of hydrogen and add high pure nitrogen, by the gas cable with detect the content that gun barrel is measured hydrogen in the molten steel, through being shown on the screen of deciding hydrogen computer instrument after the computer computing greater than 0.4Mpa.
As preferably, be connected with spring on the described chain.Speed when spring can cushion the lift cart lifting makes that detecting gun barrel can pass in and out molten steel reposefully, prevents that molten steel from splashing.
