Abstract
The utility model relates to a main body stand which is arranged on a guide rail and comprises a driving motor, a speed redactor and a traveling wheel, the top of the main body stand is provided with a lifting mechanism which comprises a motor, a hoist motor, a shaft joint, a conical gear box, a transmission shaft, a lifter, a chain and a towline, and both sides of the main body stand are respectively provided with guide devices. Furthermore, a furnace cover is fixed by the chain and the guide devices when the main body stand is used, then the main body stand horizontally moves on the guide rail and the lifting mechanism freely moves in a lifting way. The utility model is suitable for a heat treatment furnace with the diameter of the furnace cover more than 2500 mm and the lifting and the traveling of heavy furnace covers and has the advantages of safe operation, stability, convenient maintenance and high reliability.
Description
Technical field
The utility model relates to a kind of travel mechanism, particularly a kind of large-scale pit furnace bell travel mechanism.
Background technology
Traditional pit furnace bell travel mechanism is a socle girder mechanism, and its structure is generally: the single-cantilever axle, and crossbeam of welding on the cantilever shafts, three hangers of equipment are used for hanging bell on the crossbeam.This travel mechanism utilizes hydraulic efficiency system to support the lifting of whole bell, and the guiding when bell rises and lands is to be slided up and down in axle sleeve by an axis of guide to realize the location, relies on the rotation of axle to open bell simultaneously, reaches the unlatching and the closure of bell.This cantilever beam structures has significant limitation aspect load-bearing, can only be applicable to that the heat treatment furnace bell is below φ 2500mm, the bell that weight is low weight, and when using, this structure should cause cantilever shafts carrying power excessive because single-point supports, cantilever shafts has to a certain degree crooked, entire mechanism running stability and security are reduced, the bell station-keeping system is offset easily, cause the location inaccurate, repeatability is relatively poor, and bell when opening in the stove and self temperature of bell very high generally all more than 800 ℃, and the pipeline on the bell, pipeline is exposed to the lifting mechanism outside, rotate with lifting mechanism, when the appearance hydraulic efficiency system has oil leakage phenomenon, will cause very large security incident.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, proposed a kind of large-scale pit furnace bell travel mechanism of horizontal type structure, can be applicable to the large-scale pit furnace furnace cover lifting walking that weight is heavier, had and operate steadily, safe, easy to maintenance characteristics.
The technical solution of the utility model is achieved in that a kind of large-scale pit furnace bell travel mechanism, comprises a main stand, and main stand is installed on the guide rail, and the main stand bottom is provided with drive-motor, and drive-motor is connected with travelling wheel by step-down gear; The main stand top is equipped with the lifting motor, promotes motor and is connected with umbrella gear box by shaft coupling, and umbrella gear box is connected with secondary umbrella gear box respectively by transmission shaft, and secondary umbrella gear box is connected with elevator, is connected with chain below the elevator; The both sides of main stand have been installed liner respectively, and liner is connected with guide rail on the main stand by pulley.
Be provided with travel switch on the main stand simultaneously, in the side of main stand staircase be installed also, the main stand middle part is provided with drag chain.
Because the utility model adopts horizontal walker, so can be applicable to that heat treatment furnace bell diameter is more than φ 2500mm, the furnace cover lifting walking that weight is heavier, operating safety is steady, because liner has been installed, so operation is very steady when lifting and walking, owing to adopt the motor power device, avoided the safety problem that leakage produced of hydraulic efficiency system, solved pipeline, water route, gas circuit connection complicated problems, have easy to maintenance, the advantage of good reliability.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are elaborated.
With reference to Fig. 1,2, the utility model comprises a main stand 10, and main stand 10 is installed on the guide rail 13, and main stand 10 bottoms are equipped with drive-motor 14, and drive-motor 14 is connected with step-down gear 15, and step-down gear 15 is connected with travelling wheel 17 by spline 16; Main stand 10 tops are equipped with and promote motor 11, promoting motor 11 links to each other with umbrella gear box 4 by shaft coupling 18, umbrella gear box 4 is connected with secondary umbrella gear box 19,20 respectively by transmission shaft 5, and secondary umbrella gear box 19,20 is connected with elevator 2, is connected with chain 7 below the elevator 2; The both sides of main stand 10 have been installed liner 8 respectively, and liner 8 is connected with main stand 10 guide rails 6 by pulley 9; Be provided with travel switch 3 on the main stand 10 simultaneously, in the side of main stand 10 staircase 1 be installed also, the middle part of main stand 10 is provided with drag chain 12.
During use, by the fixing bell of chain 7, liner 8 one section is fixed on the bell simultaneously, drag chain 12 1 ends are connected on the bell, start then and promote motor 11, promote motor 11 and drive shaft coupling 18, shaft coupling 18 drives umbrella gear box 4, umbrella gear box 4 drives secondary umbrella gear box 19 by transmission shaft 5,20, secondary umbrella gear box 19,20 drive elevator 2 makes translational motion up and down, elevator 2 lower end fixed chains 7 can drive furnace cover lifting, and liner 8 is sliding up and down along guide rail 6 on main stand 10 under the drive of bell simultaneously, realize the guide effect of furnace cover lifting; Start drive-motor 14 then, drive-motor 14 drives step-down gear 15, and step-down gear 15 drives travelling wheel 17 and rotates, thus realization body frame 10 easy motion on guide rail 13, thus the lifting and the translational movement of realization bell.
Because the utility model adopts horizontal walker, so can be applicable to that the heat-treatment furnace bell is straight The footpath is more than φ 2500mm, and the heavier furnace cover lifting of weight is walked, and security of operation is steady, by In guider has been installed, so operation is very steady when lifting and walking, owing to adopt electricity The mechanomotive force device, the safety problem of having avoided the leakage of hydraulic system to produce, solved pipeline, Water route, gas circuit connect complicated problem, have easy to maintenance, the advantage of good reliability.
