By adopting the reaction tube lifting device for detecting the reactivity of the coke, disclosed by the utility model, the reaction tube for detecting the reactivity of the coke can be lifted to be moved from a reaction furnace, so that the potential safety hazards in the traditional technology, caused when the reaction tube is taken out of the reacting furnace, can be eliminated, and the labor intensity of operators can be reduced.
Description
Technical field
The utility model relates to a kind of coke reactivity measurement facility, and the reactive reaction tube lifting gear of measuring of a kind of coke of more specifically saying so belongs to the mechanical device technical field.
Background technology
Coke reactivity and post-reaction strength determinator are mainly used in the mensuration of used coke reactivity of blast furnace ironmaking and post-reaction strength.Among the State Standard of the People's Republic of China GB/T 4000-2008, answering property of coke and post-reaction strength test method have been introduced.Coke reactivity CRI: take by weighing the coke sample of certain mass, place reaction tube, in the time of 1100 ℃ ± 5 ℃ and carbon dioxide reaction after 2 hours, represent with the percentage of the loss of coke quality; Post reaction strength of coke CSR: reaction back coke, after drum test, represent with the mass percent that accounts for reaction back coke greater than 10 millimeters grade cokes.
Existing coke reactivity determinator comprises reacting furnace, the reaction tube in reacting furnace, and reaction tube comprises body and oral area, and the diameter of the oral area of reaction tube is greater than the diameter of body.When coke reactivity test, the body of reaction tube placed in the reacting furnace heat, the oral area of reaction tube is outside reacting furnace, and the oral area from reaction tube feeds reacting gas such as carbon dioxide simultaneously.Above-mentioned coke reactivity determinator is after reaction finishes; Need reaction tube be taken out in reacting furnace; Existing reaction tube takes out basically in the reacting furnace and protects mode by hand through gloves, wet cloth etc.; Therefore there is operational potential safety hazard, also makes operator's labour intensity bigger simultaneously.
The utility model content
To the problems referred to above, the problem that the utility model quasi-solution is determined provides the reactive reaction tube lifting gear of measuring of a kind of coke, operational potential safety hazard when in reacting furnace, taking out to eliminate reaction tube, and the work that reduces the operator is strong.
For addressing the above problem; The utility model has adopted following technical scheme: the reactive reaction tube lifting gear of measuring of a kind of coke; It comprises frame and reaction tube clamping structure, and said including rack comprises support and lifting arm, and said lifting arm is connected with the support liftable; Said reaction tube clamping structure is rotatable to be fixed on the lifting arm;
Said clamping structure comprises that clamping support, driving stem, drive block, two bendable poles and two clamp, and said driving stem is rotatable to be fixed in the clamping support, and said driving stem is provided with screw thread, and said drive block is fixed on the driving stem through screw thread; Said two clamp and comprise inlay and embedding bar respectively, and an end of said two bendable poles flexibly connects with drive block respectively, the other end is fixed with the embedding bar respectively, and the bearing of said two bendable poles and embedding bar is respectively equipped with rotating fulcrum.
Said lifting arm and support liftable are connected to: said lifting arm penetrates in the support, and fixes through cylinder and support.The rotatable structure that is fixed in the clamping support of said driving stem is: be provided with two locating pieces in the said clamping support, said driving stem passes two locating pieces.One end of said driving stem is provided with operation board.
Adopt such scheme; The reactive reaction tube lifting gear of measuring of the coke of the utility model, because frame comprises support and lifting arm, said lifting arm is connected with the support liftable; The reaction tube clamping structure is rotatable to be fixed on the lifting arm, has realized that clamping structure can move up and down and horizontally rotate.Clamp reaction tube through the reaction tube clamping structure, like this, can the reactive reaction tube of measuring of coke be promoted, shift out reacting furnace, the potential safety hazard when in reacting furnace, taking out reaction tube to eliminate tradition, the work that reduces the operator is strong.
In clamping structure, be fixed on the driving stem through screw thread through drive block, through rotation of drive rod; Can make drive block along moving on the driving stem, because an end of two bendable poles flexibly connects with drive block respectively, the other end is fixed with the embedding bar respectively, and the bearing of two bendable poles and embedding bar is respectively equipped with rotating fulcrum; When driving stem moves like this, two bendable poles are deformed, the embedding bar activity supporting point that rotates rotates; Like this, realized that inlay can clamp or decontrol reaction tube.
