Abstract
The utility model relates to a sealing double roll push rod-typed walking beam mechanism used for continuous conveying of rod-shaped work pieces through heat treatment furnaces or other furnaces, belonging to walking beam mechanism of industrial furnaces. The utility model is composed of a walking beam, a support roller, a roller frame, a lifting push rod, a sealing shaft sleeve, a lifting frame, a support roller, a ramp rail, an oxide scale cleaning hole, a fixed beam and a lifting hydrocylinder, wherein, the walking beam can be built in sections and installed in a furnace without leaving installation area in the workshop; the lifting push rod can be sealed with the sealing shaft sleeve rather than a water sealing tank, which consequently reduces heat loss and is in favor of eliminating the black mark generated during work piece heating. In addition, the square cone-shaped oxide scale cleaning hole is left on the furnace bottom, which is benefit for the cleanness of the oxide scale.
Description
The utility model relates to a kind of stove walking beam mechanism, is used for the continuous conveying to the rod workpiece of heat-treatment furnace or other kilns.
In walking beam furnace, workpiece is placed on one group of walking beam and the built-in beam, the walking beam and the built-in beam of high temperature furnace are water-cooling structure, the external application refractory material, walking beam is at the regular-shape motion of doing repeatedly to rise-advance-descend-retreat, be placed on the built-in beam workpiece not with track generation friction situation under, transport forward step by step.
Existing walking beam mechanism has following several pattern:
A kind of is the eccentric wheel type walking beam mechanism, see Fig. 3 (the industrial furnace handbook, Japanese industry stove association compiles, metallurgical industry publishing house, in April, 1989 front page, 170 pages).Motor drives eccentric wheel makes walking beam do rising, descending motion repeatedly.And advancing and retreating by hydraulic cylinder of walking beam moves back and forth realization.The weak point of this mechanism is: no matter whether the walking beam water-cooled, and the water sealed tank sealing must be adopted in the gap between walking beam and the built-in beam, prevents that cold air from infiltrating, see Fig. 6, therefore increased the water-cooled heat loss, water sealed tank produces steam under the furnace temperature radiation, escape into the oxidation that has increased workpiece in the stove.In addition, the mass activity beam is packed into or pull out stove and repair outward, need take the workshop than large tracts of land.
A kind of oblique rail formula walking beam mechanism is seen Fig. 4, and the lifting of walking beam drives bogie wheel along tiltedly rail reciprocating motion realization by lower cylinder, and its weak point is identical with the eccentric wheel pattern.
Another kind is the lever-linked formula of roller, sees Fig. 5, and the lifting of walking beam is to drive lever system by lower cylinder, and roller is realized around the fulcrum revolution.Its weak point is identical with the first two kind situation.
A kind of sealing crank push-down walking beam mechanism of U.S. Loftus engineering company, see Fig. 7 (industrial furnace volume two, work such as W Trinks, metallurgical industry publishing house, in April, 1979, front page was 267 pages), walking beam is supported on the roller on push rod top, and push rod carries out lifting by crank and hydraulically powered pull bar.With the sealing device sealing, walking beam is the heat-resisting alloy structure of rectangular cross section between push rod and the body of heater.This has just saved water sealed tank, but this structure can only be used under the condition of protective atmosphere or reduction burning, otherwise, in case the oxide skin on the workpiece falls in the gap between lifting push rod and slotted eye, causing mechanism-trouble easily, oxide skin also can't be cleared up.In addition, a push rod has only a roller, the influence operation in case roller damages, and do not have the walking beam guider.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of water seal that do not need is provided, and the sectional manufacturing is convenient to install, repair, the sealing double roll push-down walking beam mechanism that the life-span is long.
The utility model is realized by following measure:
Sealing double roll push-down walking beam mechanism is by walking beam, support roller, and turning rolls, the lifting push rod, sealing axle sleeve, crane, bogie wheel, oblique rail, the oxide skin cleaning eye, built-in beam is formed.Walking beam, built-in beam all can the segmentation manufacturings, assembling in the stove.The section of walking beam is I-shaped or Y font (being used for casual labourer's part), and the bottom surface is the plane, and end face is equidistantly arranged and is the Asymmetric V-type groove, is beneficial to round rod member like this and rolls when mobile, thereby eliminate " the black seal " that workpiece occurs because of heating.Walking beam is supported by a pair of support roller, support roller is contained on the turning rolls on the lifting push rod, turning rolls is the mountain font, the middle high lateral margin that rises plays the walking beam guide effect, because a pair of support roller is arranged, in case a roller damages, another can be worked as usual, do not influence the normal operation of walking beam, and under the bigger situation of lifting push rod spacing, can reduce the walking beam length of support, help improving walking beam service life, in addition, turning rolls has covered lifting push rod slotted eye gap, prevents falling into of oxide skin.
The lifting of walking beam drives bogie wheel along tiltedly rail reciprocating motion realization by lifting hydraulic cylinder, and the lifting push rod is by sealing axle sleeve lifting and sealing.
The walking beam of segmentation manufacturing can be assembled into different length as required in stove, need not the outer standby erection space of stove.Be scale blowing, the side of leaving, bottom taper oxide skin cleaning eye can clean out oxide skin after opening.
The utility model compared with prior art has following advantage:
1. with the sealing axle sleeve sealing, need not water sealed tank and cooling water, can reduce the stove heat loss, eliminated the harm that steam brings.
2. the walking beam sectional is made, and assembles in stove, need not standby erection space, improves the workshop area utilization.
3. the V-shaped groove of walking beam end face rolls circular material when stepping, is beneficial to eliminate heating " black seal ".
4. a lifting push rod is equipped with two rollers, in case one damage another and can work as usual, and under the situation that reduces lifting push rod quantity (increase its spacing), shorten the walking beam length of support, be beneficial to and prevent the walking beam deflection, increase the service life.
5. turning rolls covers lifting push rod slotted eye gap, prevents that oxide skin from falling into.
6. be provided with the oxide skin cleaning eye, be convenient to scale blowing.
