Abstract
The invention provides a chain tensioning gear and a chain tensioning method for a slag removing machine. The chain tensioning gear is formed by a fixing seat, supporting screw rods, springs, adjusting nuts, slideway supports, a chain, tension sprockets, a sprocket shaft, slide blocks, bearings, a support connecting plate and a screw rod connecting plate. When the stretching and retracting action of a telescopic boom of the slag removing machine is finished, the tension sprockets move downwards under the action of the springs, and are in a free tension state; when the telescopic boom is retracted or stretched, the vertical vibration of the chain can be restrained by the tension sprockets and the meshed chain; when the chain is stretched, the nuts can be adjusted so as to change the precompression of the springs; when a transverse force is caused by the chain, a reserved gap can enable the tension sprockets to move transversely, and transverse floating supporting guide is realized; when a pull force of the chain is changed, the chain does vertical movement along with the tension sprockets, and partial momentary tension is relieved or eliminated. The chain tensioning gear and the method provided by the invention can be used for effectively relieving impact load caused by frequent reversing, the chain transmission stress state can be improved, the service life of the chain can be prolonged, and the running reliability of the chain can be improved.
Description
Technical field
The invention belongs to the transmission device field, relate in particular to a kind of tension device for the Cinder Machine chain and tensioning method thereof.
Background technique
The tradition Cinder Machine adopts slag removal device to skim, and slag removal device is fixed on the Cinder Machine telescopic boom, with telescopic boom all around, upper inferior direction action, containing sulphur-slag is taken off in the slag ladle of below.The expanding-contracting action of telescopic boom is completed by fluid motor-driven, chain and sprocket driving.Because expanding-contracting action is frequent, the oil hydraulic motor commutation is very large to the impact of chain, and service life of chain is low, and abnormal damage has a strong impact on carrying out smoothly of production.
The chain transmission is to belong to the engagement driving with middle flexible element, and it has gear transmission concurrently and with the Some features of transmission.Chain damages generally fatigue ruption, wearing and tearing, gummed etc., and wherein gummed damages with lubricated too high relevant with rotating speed; Wearing and tearing are relevant with the position between drive sprocket and driven sprocket and upper saw pulley; In the closed kinematic chain transmission, fatigue ruption is relevant with cycle-index and impulsive load; In the situation that lubricated suitable, fatigue ruption is the principal element that determines the chain transmission capacity.Chaindriven wearing and tearing generally arrange to guarantee by position and the proportional space adjusted between drive sprocket and driven sprocket, upper saw pulley.When between drive sprocket and driven sprocket, upper saw pulley, position changes, the thrust that may cause carrier bar additionally to bear jockey sprocket, cause the chain stress to worsen and very easily damage.
Chaindriven fatigue ruption generally adopts tension device to reduce impact.But up to now, still be not applicable to the chaindriven tension device of this frequent commutation of Cinder Machine fully.
Summary of the invention
The present invention aims to provide a kind of the realization and automatically adjusts on three-dimensional, effectively alleviates the impulsive load that frequent commutation brings, and improves the chain transmission stress, improves Cinder Machine chain stretching device and the method for chain working life and operational reliability.
For this reason, the solution that the present invention takes is:
A kind of Cinder Machine chain stretching device, is characterized in that, fixed base, studdle, spring, adjusting nut, slideway support, chain, tension sprocket, sprocket shaft, slide block, bearing, bearing connecting plate and screw rod connecting plate, consists of; Upper end at " U " shape fixed base respectively is welded with an outwardly directed transverse slat, the transverse slat inboard is fixed with respectively a slideway support, two slideway support upper ends are fixed together by the bearing connecting plate, and the transverse slat outside connects respectively a studdle, and studdle penetrates in the slide block screw hole; Middle part is provided with limiting block, inner end is connected on slideway support with the slide block inner slide of stomidium, and sprocket shaft one end be arranged in the slide block stomidium is locked with positioning screwn, is reserved with gap between at the bottom of the other end and stomidium hole; With the tension sprocket of chain engagement, by bearing, be installed on sprocket shaft; Spring is equipped with on studdle top, spring lower end connection sliding block, and the spring upper end is provided with adjusting nut, is fixed with the screw rod connecting plate above adjusting nut; Fixed base is connected to Cinder Machine and supports on transverse arm.
All leave gap between described slide block limiting block and slideway support and between studdle and slide block screw hole.
A kind of Cinder Machine chain tension method, is characterized in that, concrete grammar is:
The fixed base of chain stretching device is welded on the support transverse arm between Cinder Machine drive sprocket and jockey sprocket, and the tension sprocket engagement is pressed against above chain;
When the Cinder Machine telescopic boom stretch out or retract action at the end, oil hydraulic motor stops, chain proceeds to halted state by working state, the tension sprocket of chain stretching device moves down under the precompression of spring, makes chain be free tensioning state; When the Cinder Machine telescopic boom starts to retract or stretches out, the oil hydraulic motor reverse starting, tension sprocket is subject to the pulling force that chain makes progress and is greater than the downward precompression of spring, make tension sprocket and with the chain of its engagement while rotating slow lifting, the vibration up and down of constraint chain, realize effective buffering and auto-tensioning in frequent commutation process;
Occur stretching when long when chain uses a period of time, changes the precompression of spring by adjusting nut, adjusting is applied to the initial tension on chain;
When transverse force that positional deviation brings appears in chain, between at the bottom of sprocket shaft and stomidium hole, between slide block limiting block and slideway support and the preset clearance between studdle and slide block screw hole will make tension sprocket laterally moving among a small circle, realize the laterally floating support guide;
When chain is subject to the pulling force sudden transition on direction forward or backward, chain will be done the motion of upper and lower Vertical direction along with tension sprocket, slow down and eliminate part moment tension force, improve the stress of chain.
Beneficial effect of the present invention is:
The present invention can realize that chain is upper and lower, all around is the automatic adjustment on three-dimensional, makes chain along on the sprocket driving direction, keeping tensioning state, guarantees that carrier bar bears the lateral thrust that upper saw pulley brings simultaneously; Tension device possesses the function of moving left and right, and can make Idle wheel have the initiative all the time on " two one lines " of sprocket wheel and driven sprocket; Tension device possesses the function of moving up and down, and makes tension force have automatic compensation function.Therefore, the impulsive load that frequent commutation brings can be effectively alleviated in the present invention, improves the chain transmission stress, improves chain working life and operational reliability.
