Description
Technical field
The application relates to a kind of kiln bell, is specially a kind of heating furnace kiln bell that can be elevated.
Background technology
Kiln is the equipment in order to burnt product be built into refractory material, be pottery art shaping in indispensable facility.Mankind's pottery of up to ten thousand years burns makes history, have accumulated abundant to make kiln pattern and experience.From the ground of primitive society outdoor burnt in a heap, digging pit to build burns steamed bun shape and rises flame circular kiln, half downdraf horse shoe flame furnace, half way up the mountain dragon kiln, oval kiln, then to Indoor Air kiln, electrical kiln now, kiln science and technology is in continuous improvement.
And due to the high-temperature behavior of kiln, its bell requires can be heat insulation, its weight is often heavier, and in use, needs again to open to check situation in stove to bell.
The higher pair mechanism that cam mechanism is made up of cam, driven member and frame three basic building blocks.Cam is a component with curved profile or groove, is generally driving link, makes constant speed gyration or linear reciprocating motion.
Contact with cam contour, and transmit power and the component realizing the predetermined characteristics of motion, generally do linear reciprocating motion or swing, be called driven member, or the bell body be lifting.
Cam mechanism basic characteristics are in the application to make driven member obtain the more complicated characteristics of motion.Because the characteristics of motion of driven member depends on cam profile curve, so when applying, as long as the contour curve designing cam according to the characteristics of motion of driven member is just passable.
Cam mechanism is widely used in various automation, instrument and maneuver control device.Why cam mechanism obtains so is applied widely, and mainly because cam mechanism can realize the movement needs of various complexity, and structure is simple, compact.Cam lifting mechanism has the simple and reliable advantage of operation, needs to be widely used in the device controlling to be elevated at some.
Due to the higher pair performance of cam, often need to lock its position.And the motion conversion between the out of phase of cam, often need to apply active drive power.Apply active drive power continually, be disadvantageous for driving mechanism.And when for driving power device disappearance or fault, then become difficulty in a kind of phase place of cam to the transfer of another phase place and arrange infeasible.
Summary of the invention
The invention provides a kind of heating furnace kiln bell that can be elevated, it is when being shifted to another cam phase by a kind of cam phase, and without the need to restarting or applying active drive power, and the phase position of cam is stablized, stress equalization.
According to the present invention, a kind of heating furnace kiln bell that can be elevated, it can be elevated thus realizes the unlatching of kiln and close, described bell comprises bell body, frame, eccentric wheel, stop pin, resiliency urged pin and limited post, described eccentric shape is as general as round-shaped, and be provided with drive shaft prejudicially, when the described round-shaped center of circle be positioned at the top of described drive shaft and relation vertical with its formation time, described bell body is risen to a high position by described eccentric wheel; Described eccentric periphery is also provided with radially-inwardly recessed lock hole, lock hole is used for coordinating with the upper end of stop pin, when described bell body is risen to a high position by described eccentric wheel, lock hole is positioned at the below of described drive shaft and relation vertical with its formation; The lower end of stop pin is connected with stop pin spring, and under the top pressure effect of stop pin spring, stop pin can stretch into described lock hole when described bell body is risen to a high position by described eccentric wheel thus lock eccentric wheel; The lower end of stop pin also couples with latch-release pull-down member, and latch-release pull-down member is used for stop pin is drop-down and contact locks;
Eccentric wheel is also provided with acute angle shape part, under described bell body being risen to high-order state at described eccentric wheel, down, and left surface is vertical direction to described acute angle shape part tip, right flank and described eccentric outer circumference surface tangent, and intersect acute angle with left surface; The described left surface of acute angle shape part is the drive surface for engaging with the right-hand member of resiliency urged pin, and described right flank is the loading end being used for carrying described bell body when described bell body is down to low level by described eccentric wheel;
The right-hand member of resiliency urged pin is rounded shape, and left end is connected with promotion spring, and the rounded shape of described right-hand member is used for engaging with drive surface, the position, middle part of stop pin is fixedly installed voussoir, and the upper side of described voussoir is tapered ramp, and described tapered ramp is parallel to the axis direction of described drive shaft, and acutangulates with horizontal plane, resiliency urged pin is near its right-hand member, the inclined-plane notch inserted for described voussoir is provided with between its right-hand member and left end, the left surface of described inclined-plane notch is the engagement ramp for coordinating with described tapered ramp, when stop pin is in the lock-out state stretched in described lock hole, stop pin is coordinated with the engagement ramp of resiliency urged pin by described tapered ramp and resiliency urged pin is pressed to left side simultaneously against promoting spring, thus it is moved right lock, now, between the right-hand member of resiliency urged pin and the drive surface of acute angle shape part, there is gap and do not engage,
When latch-release pull-down member applies transient state effect to stop pin, and when it is drop-down, the upper end of stop pin departs from from eccentric lock hole, meanwhile, voussoir to exit and tapered ramp is disengaged with engagement ramp from inclined-plane notch, thus, the right-hand member of resiliency urged pin engages the described drive surface of acute angle shape part, eccentric wheel is rotated counterclockwise, and thus, bell body is down to low level gradually; Described limited post is connected to frame by spacing flexible member, and when eccentric wheel rotates counterclockwise and makes bell body be down to low level, horizontally, and the outer end of loading end contacts with limited post thus carries out spacing the loading end of acute angle shape part;
When needs make bell body rise to a high position from described low level, drive shaft drives eccentric wheel to rotate clockwise, in the process, slide along eccentric circumferential outer surface in the upper end of stop pin under the top pressure effect of its stop pin spring, and the drive surface of acute angle shape part can turn to and be combined with the right-hand member of resiliency urged pin, thus gradually it is pushed up pressure to the left; When the upper end of stop pin starts to fall into lock hole, stop pin moves straight up in the top of stop pin spring pressure entirety, and now, voussoir can insert the inclined-plane notch of resiliency urged pin thus be promoted left further by resiliency urged pin; Realize the locking of bell body in a high position thus.
By such scheme, while bell body being risen to a high position by low level at elevating mechanism, the spring members of telescoping mechanism be have accumulated a large amount of potential energy; When needs are changed to low level by a high position, utilize the elastic potential energy drive cam put aside to rotate to the direction expected, utilize gravitional force afterwards and be down to low level voluntarily.And, by locking mechanism, while locking cam upper level position, also described elastic telescopic mechanism is locked, avoid elastic force to be applied directly to cam mechanism, therefore avoid and affect the stability of cam mechanism in a high position.Utilize acute angle shape part, while being used as to coordinate with described telescoping mechanism the drive surface contacted, also when low level as loading end, the crank caused with the skew of bell body contact position that the eccentric setting avoiding cam mechanism causes.By limiting component, both ensure that the horizontal position after cam rotation, served again the effect of stable low-end trim.
