Abstract
The utility model discloses a ladle outer installed ventilation brick hot drawing device which comprises a pair of trapezoidal screw bolt and screw nut, wherein the outer periphery of the trapezoidal screw bolt is provided with a supporting sleeve barrel. One end of the trapezoidal screw bolt extends to the front end surface of the supporting sleeve barrel and is connected with the trapezoidal screw nut via a plane bearing which clings on the front end surface of the supporting sleeve barrel, the other end of the trapezoidal screw bolt extends to a back opening surface of the supporting sleeve barrel and fits with the thread of a connecting screw nut which is fixed on the outer installed ventilation brick. Using the full mechanical design, the utility model is simple in structure, convenient to operate, high in working efficiency, low in error rate, and low in production and maintenance costs, further the utility model is applicable for changing the ladle outer installed ventilation bricks.
Description
Technical field
The utility model relates to a kind of metallurgical industry service equipment, specifically, is a kind of ladle externally installed permeable brick hot drawing device.
Background technology
Be used for the fitted outside air brick that the molten steel Argon uses and be embedded in the ventilative square brick, in the ladle circular flow, need online replacing.What the dismounting air brick used is disassembling furnace machine always, and invar bag inner wall temperature is more than 800 ℃, and disassembling furnace machine need be in operation under the hot environment, and its hydraulic system is easy to damage, and causes the disassembling furnace machine fault rate high, and the maintenance cost costliness.Because the fault rate height, it is very inconvenient to operate, and changes at most only 6 of air brick quantity every day, and operating efficiency is extremely low.And, also be necessary for the place that huge disassembling furnace machine is provided with an operation specially and parks, and, also need the personnel of Fourth Shift machine to be safeguarded use cost is high for disassembling furnace machine is equipped with a professional operator in order to guarantee its routine work.Also find no a kind of good technical scheme at present and solve this type of problem.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background, proposes a kind of simple in structure, simple operation, high efficiency and fault rate is low, use cost is low ladle externally installed permeable brick hot drawing device.
At above-mentioned purpose, the ladle externally installed permeable brick hot drawing device that the utility model is designed, comprise a pair of trapezoidal screw and trapezoidal nut, the periphery of described trapezoidal screw is arranged with a stop sleeve, one end of described trapezoidal screw stretches out the front end face of stop sleeve and passes the plane bearing that is close to the stop sleeve front end face and links to each other with the trapezoidal nut screw thread, the other end of described trapezoidal screw stretch out stop sleeve the after-opening face, be fixed on attaching nut's threaded engagement on the externally installed permeable brick.
Further, said trapezoidal nut is provided with turning handle.
Further, the afterbody of said stop sleeve is provided with and can be close to the ventilative lip-deep backing plate of square brick.
Advantage of the present utility model is: whole device adopts simple frame for movement to replace baroque disassembling furnace machine, has greatly reduced manufacturing cost and use cost; Simultaneously, whole device is easy and simple to handle, need not to be equipped with the professional operator, has saved human resources; This device is owing to adopt simple frame for movement, fault rate is extremely low, greatly improved service efficiency, reduced maintenance cost, and the structure that device has adopted distinctive nut and screw rod to cooperate, the axial force of utilizing the nut rotation to produce is extracted brick, improves greatly with respect to original disassembling furnace machine operating efficiency.
Description of drawings
Accompanying drawing is the structural representation of ladle externally installed permeable brick hot drawing device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in drawings, the designed ladle externally installed permeable brick hot drawing device of the utility model has a pair of trapezoidal screw 1 and trapezoidal nut 2.The periphery of described trapezoidal screw 1 is with a stop sleeve 4, and the length of described stop sleeve 4 is less than trapezoidal screw 1.Trapezoidal screw 1 one ends stretch out the front end face of stop sleeve 4, and pass the plane bearing 3 that is close to stop sleeve 4 front end faces and link to each other with trapezoidal nut 2 screw threads.Like this, trapezoidal nut 2 and stop sleeve 4 are all free to rotate, when trapezoidal nut 2 drives trapezoidal screw 1 rotation, can not be subjected to the influence of stop sleeve 4.The other end of described trapezoidal screw 1 stretches out stop sleeve 4 after-opening faces, with attaching nut's 5 threaded engagement that are fixed on the externally installed permeable brick 6.When pulling out externally installed permeable brick 6, the other end precession of trapezoidal screw 1 is fixed in the attaching nut 5 on the externally installed permeable brick 6, and trapezoidal screw 1 and externally installed permeable brick 6 are connected as a single entity.For ease of rotation trapezoidal nut 2, be set with turning handle 8 in the outside of trapezoidal nut 2.For avoiding in the process of pulling out externally installed permeable brick 6 the bad ventilative square brick 7 in stop sleeve 4 tops, be provided with at the afterbody of stop sleeve 4 and can be close to ventilative square brick 7 lip-deep backing plates 9.
The course of work of this device is such: when needs were changed externally installed permeable brick 6, at first the stop sleeve 4 with this device withstood on ventilative square brick 7 surfaces; An end precession that then trapezoidal screw 1 is positioned at stop sleeve 4 after-opening faces is fixedly set in the attaching nut 5 in externally installed permeable brick 6 outsides, makes trapezoidal screw 1 and externally installed permeable brick 6 be connected as a single entity; Constantly rotate trapezoidal nut 2 after this, because the rotation of trapezoidal nut 2 makes trapezoidal screw 1 obtain bigger axial force to the left, thereby pulling attaching nut 5 and externally installed permeable brick 6 translation to the left of fixedlying connected with it is until externally installed permeable brick 6 is extracted.
