Abstract
Eccentric disks (15, 16, 17) are used in tamping devices to drive a tamping rod (7), whereby said disks consist of an outer tamping segment ring (1, 1'), an inner embossed ring (2, 2a, 2b) and a central elastic ring (3, 3A) made of rubber. This configuration is the same for all eccentric disks. The embossed ring (2, 2a) and a clamping and withdrawal sleeve (4) enable the individual eccentric disks (15, 16) to be mounted at any point on the disk shaft (6), whereby stepped shafts can be done away with. The inventive design leads to savings in both capital investment and operating costs.
Description
The present invention relates to a kind of ramming device that is applicable to the compacting briquette that making coking is used, this ramming device has the tamping rod that is evenly distributed on the whole length of tamping mould.On the dividing plate of this tamping rod, both sides are provided with friction plate, and the cam-engaged that has the cam-like fan-shaped section is in this friction plate, and these cams removably are contained on the camshaft of a common rotation, and have a hub diameter consistent with corresponding shaft part.
As everyone knows, in order to improve the coke quality, coking coal must carry out compacting with free-falling packer in a tamping mould that for this reason is provided with, then coke furnace is put into or pushed to the briquette of compacting.The tamping rod generally makes double tee section, wherein is provided with a friction plate in connection dividing plate both sides.Mesh two opposed cams symmetrically on this piece dividing plate of band friction plate, then each is installed on the root continuous axle and has the segmentation of a cam-like this cam, promotes single packer by the cam segmentation under the frictional force effect.Wherein, in the both sides of dividing plate, the cam respective action is on this plate.When continuing rotation, cam discharges the tamping rod again in the zone that resets of its circumference, so this tamping rod falls and with its tamping base compacting coking coal.Single cam staggers 90 ° and is arranged on the successive axle, so the single vertically interior tamping rod of tamping mould that is arranged in rises with certain beat, freely falls then.Corresponding cam can be referring to German patent DE-OS2603677.1.
This known cam is made up of the lift cam of a hub member that has a central dividing plate, circular supporting snubber, fixed side and protrusion.The lifting of the tamping rod that produces through rotatablely moving of cam realizes by a hub member that is fastened on the camshaft with wedge.Camshaft is delivered to frictional force on the lift cam of projection of cam and is undertaken by the circular buffer that is distributed on the cam circumference.One side of these snubbers is connected with the central dividing plate of hub member, and opposite side then is connected by screw with the fixed side of holding lift cam.This circular supporting snubber is made with a kind of rubbermeter of circle, and this rubbermeter has the metal sulphide plate that an available screw is screwed at head end and bottom.This circular supporting snubber is to consider that so promptly it must at first bear compressive load from its design aspect.The ratio of the ability to bear of compressive load and shear load is 3: 1.For this reason, this circular supporting snubber almost only uses as damping element concerning machine supports.As mentioned above, the lifting of tamping rod is that the friction by cam connects and realizes, and this friction connects and is to realize towards the rotation of the lift cam section of projection by hub member.The shortcoming of this known structure is, single circular supporting snubber bears torsion load, and this is the principle of design that does not meet it.So cam can only have the very short life-span.Another shortcoming is that cams mounted successive axle has the pillow block of staggered arrangement, so that cam can be installed on the long axle bed.Because this regulation, cam must make different structures all the time, that is has different hub diameters, so must keep considerable acknowledgment copy.Because it is identical that the keyway on the supporting camshaft makes, and axially in line, so need the cam of the other additional different structure of deposit owing to the sectional of cam or cam-like is staggeredly arranged.
So the objective of the invention is to, propose a kind of ramming device life-span length and cam unified structure that has.
According to the present invention, this purpose is to realize like this, this cam has cam-like sectional lifting eccentric circular ring by one and a nave collar that for this reason is provided with is at a certain distance formed, and they are by the firmly connection mutually of a resilient ring, and nave collar is connected with transmission shaft is antitorque.
In the ramming device that constitutes like this, the lifting eccentric circular ring of expression cam is connected by a resilient ring with nave collar comprehensively, so always form the uniform connection that rubs around between cam and the tamping rod to be hoisted.In addition, avoided the storage cost of various cam kind, because all cam all makes identical structure, promptly had a nave collar, this nave collar preferably has a circular cone in axle one side and cooperates.So just can use continuous axle that is the available camshaft of making by the tensile bearing materials that does not have pillow block.Cam distance in accordance with regulations on camshaft that structure is identical is fixed on the optional position with suitable fastening piece.Be issued to the long life-span and the production cost of much less with solution of the present invention in the situation of the very low deposit of single cam,, can have reduced investment cost again so both can reduce cost of business operation.
Resilient ring is connected with lifting eccentric circular ring (constituting a cam) with nave collar.According to a suitable scheme, nave collar and promote eccentric circular ring and make with metal and vulcanize resilient ring thereon.Guaranteed that by this sulfuration nave collar, lifting eccentric circular ring effectively are connected on entire contact surface mutually with resilient ring, thereby frictional force can be delivered to the tamping rod effectively by cam.But also can imagine nave collar, resilient ring and lifting eccentric circular ring bonds together mutually.Can guarantee the corresponding effectively bonding of these parts according to the tackiness agent that provides at present.
According to a suitable scheme, the circular cone cooperation has an obliquity of 1: 12, so just can be fixed on corresponding cam or nave collar on the camshaft effectively with proper implements.The lift cam of lifting eccentric circular ring configuration that preferably should seal, this lift cam has an inlet and an outlet.So just guaranteed uniform running.
In order to simplify installation, according to another scheme, cam is formed by two or more segmentations are fan-shaped, and these fan-shaped removably connections also mutually by a tie point reliably evenly are fitted on the dividing plate of tamping rod.Wherein available a kind of screw connects, and makes it stretch into resilient ring always, thereby improves simultaneously and being connected of resilient ring.Resilient ring is made two portions, takes turns nave collar in case of necessity and also makes two portions, so just need not shift them on the axle onto, and can install on the spot, and this also suits.
The notion of resilient ring is, it is made by a kind of resilient material, and it is suitable especially wherein making resilient ring with a kind of rubber material, and with this rubber material sulfuration at nave collar with to promote on the eccentric circular ring then be favourable.In order to increase elasticity, this resilient ring also can have such belly, and this belly at first reduces in lifting eccentric circular ring direction from nave collar, increases again then.
When nave collar and/or promote eccentric circular ring on the face that faces toward mutually for the surface of hacking or convexo-concave is desirable when connecting, then resilient ring and nave collar and with lifting the bonding of eccentric circular ring be particularly advantageous.Here it also is favourable connecting with mortise, if guarantee to insert in the hole tenon do not rupture.If connect with mortise or even advantageous promoting on the eccentric circular ring, because the rubber material under certain condition even increased friction effect on the dividing plate of tamping rod.
According to a scheme of the present invention, cam fixedly is being to reach optimizing and simplification like this on camshaft promptly on the axle, and promptly nave collar has disposed one can carry out axially movable gripping sleeve on axle.This gripping sleeve is close on the axle, promptly preferably is close to cam fixed position, so cam is sleeved on the gripping sleeve.Like this, not only can cancel the step-like pillow block of aforesaid camshaft, also can reach the optional position that cam reliably is arranged in camshaft, promptly cam is enclosed within on the gripping sleeve.When putting, simultaneously the segmentation of cam-like is moved on to the position that respective cams is provided with.
Come to fix to clamp cover together simultaneously by splined nut of nave collar configuration, just can prevent reversing unintentionally or becoming flexible of cam in service.This splined nut is pressed on the corresponding segment of gripping sleeve on the axle, and has guaranteed that thus gripping sleeve does not leave its position, or nave collar cooperates by opposite circular cone and gripping sleeve is fixed together.
Have a splined nut to fix gripping sleeve and nave collar in order always to guarantee when mounted, according to the present invention, splined nut is connected in head one side with nave collar.This splined nut just just in time is positioned at the critical positions of fixing each parts like this.
Gripping sleeve is made the installation that the two portions that can overlap mutually in the marginarium can further be simplified gripping sleeve.Like this, gripping sleeve can be contained on the already installed axle, and does not need axle is unclamped from any bearing or transmission mechanism.Because two portions of gripping sleeve overlap mutually in the marginarium, promptly preferably alternately overlap, so do not need usually to be fixed on the axle separately.Exactly, as previously mentioned, gripping sleeve is fixed on the axle simultaneously by splined nut and wheel nave collar.In addition, the nave collar that moves by two portions gripping sleeve has guaranteed that two portions gripping sleeve cannot not be in operation looseningly, promptly remains on the position of regulation reliably.
But before nave collar or cam are pushed to, also can make two portions gripping sleeve become parts, promptly two portions of gripping sleeve be interconnected in the marginarium, preferably bonding.Like this, when pushing to cam, gripping sleeve is close on the axle, so only need to carry out foregoing additional fastening on nave collar or its single parts.
According to another suitable scheme of the present invention, gripping sleeve has one or more distributing grooves and oil supply hole, can carry out favourable oil pressure installation or removal like this.Other suitable improvement can be learnt from every additional dependent claims.
Particularly, the ramming device that the present invention proposes is characterised in that because the simple and unified structure of single cam has been simplified the installation of single cam greatly, this obviously reduces manufacturing cost.All cam is furnished with identical nave collar and promotes eccentric circular ring and be furnished with the resilient ring that is connected them.The torsion that cam produces between the lifting eccentric circular ring in when operation and nave collar has obtained best transmission by the resilient ring that integral body constitutes, and has so just increased the life-span significantly.In addition, as previously mentioned, the structure of single cam is identical, and this is favourable, wherein nave collar have that circular cone cooperates and with or can make up like this with gripping sleeve, make single cam in fact can be installed in the optional position of the continuous axle of same cross-sectional.Because without the step-like pillow block of camshaft, so simplified installation widely.By this structure, particularly also investment cost and cost of business operation have obviously been reduced owing to favourable stores keeping.
