Abstract
The invention discloses a vacuum pipeline sealing device for a double-station RH system, and relates to the technical field of RH vacuum treatment. In order to overcome the defect that the conventional sealing device has poor sealing effect, cannot accurately perform positioning, and has long positioning time and short service life, the invention provides the vacuum pipeline sealing device for the double-station RH system. A sealing bend is shifted and lifted through a trolley, and the trolley is shifted through a variable frequency reducer motor; the sealing bend is arranged in the sealing trolley, and is connected with a synchronizing shaft through a chain and a guide wheel; and one end of a hydraulic cylinder is fixed to a trolley frame, while the other end is connected with the synchronizing shaft, and the lifting of the sealing bend is realized through the expansion of a hydraulic rod. The vacuum pipeline sealing device ensures quick and accurate positioning of two ends of the sealing bend and a condenser and a delivery duct, and good sealing effect, reduces the maintenance of equipment, prolongs the service life of the equipment and is favorable for promotion and application.

Steel-making RH vacuum processing technique has high requirements to system's resistance to air loss, and the sealing effectiveness of the vacuum pump of double-station RH system and pipeline is directly connected to the vacuum treated final success or failure of RH in the production process.Therefore, how to guarantee that the vacuum pump and the sealing effectiveness of pipeline have just become an important topic of double-station RH system.
Double-station RH system has a two condensers and a cover transport pipe, wherein during a RH system works, needs to use a sealing bend to couple together with the condenser and the transport pipe of its correspondence.At present, domestic mainly is that the mode of electric block is transported sealing bend, though investment simple in structure is less, there are the following problems: 1. sealing effectiveness is poor, because electric block does not have liner, sealing bend can not accurately be located; 2. electric block rocks greatlyyer in operational process, makes sealing bend setting time long and equipment life is shorter.How to guarantee that the double-station RH system vacuum pump has just become a suitable stubborn problem with the sealing effectiveness of pipeline.
Summary of the invention
In order to overcome the defective that exists in the prior art, the invention provides a kind of vacuum pipeline sealing device of double-station RH system, make the good seal of vacuum pump and pipeline, reduce maintenance simultaneously, prolong service life of equipment.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of vacuum pipeline sealing device of double-station RH system, comprise sealing bend and be used to transport the device of sealing bend, described sealing bend relies on travelling bogie to carry out translation and lifting, concrete structure is: on the described travelling bogie variable frequency reducer motor is installed, realizes the translation of travelling bogie by variable frequency reducer motor; Described sealing bend is arranged in the sealing dolly, and sealing bend is connected with synchronizing shaft with guide wheel by chain; Hydro-cylinder one end is fixed in vehicle frame, and the other end is connected with synchronizing shaft, the lifting of the flexible realization sealing bend by hydraulic stem.
The two ends of described sealing bend all are connected with one group of chain respectively; Described hydro-cylinder is two and is separately positioned on the position at sealing bend two ends, and described two hydro-cylinder afterbody earrings are fixed in travelling bogie, and the head earrings all is connected with same synchronizing shaft, and synchronizing shaft is connected with sealing bend with guide wheel by chain again.
Described tightness system also comprises travel switch, and described travel switch is fixed in ground, by the collision block trigger switch on the travelling bogie vehicle frame and send the accurate off-position that electrical signal is realized travelling bogie.
Described tightness system also comprises drag chain, and an end of described drag chain is fixed in ground, and the other end is connected with travelling bogie, is used for the electric power of travelling bogie and the energy medium of hydraulic efficiency oil and carries.
Compared with prior art, the beneficial effect of technical scheme generation of the present invention is as follows:
The present invention has satisfied the special service requirements of double-station RH system, adopted travelling bogie to realize the translation and the lifting of sealing bend, adopt variable-frequency motor and travel switch to make the translation off-position of sealing bend accurate, adopt hydraulic way to make the lifting of sealing bend stable rapidly, adopt drag chain to be used for the energy medium conveying of the electric power and the hydraulic efficiency oil of travelling bogie, said structure has guaranteed the two ends and the condenser of sealing bend and transport pipe carries out fast, accurately location, so good sealing effect; The present invention has simultaneously also reduced the maintenance of equipment, has prolonged the work-ing life of equipment, is beneficial to and applies.
