Description

Machine for maintaining and repairing stamps of coking oven chargers

The coal that coking is used is placed in the furnace charge case by the pudddler compacting.Pudddler comprises a beater at least, and beater has a firm shoe to be fixed on the bottom of an I-shape beam.All there is the pad of a high coefficient of friction both sides of the I-shape beam soffit of girder, pad and a pair of relative eccentric wheel concerted action, and eccentric wheel has rotating power and is driven.During each the rotation, two eccentric wheels are clamped the soffit of girder it are vertically moved up.When the gap between the two eccentric drive faces increased owing to eccentric effect, beater was released and freely drops on the coal seam in the case.This to-and-fro motion takes place in a stroke, and this stroke is compared very little with the whole length of beam.Stroke only takes place in a part of length of beam, and moves along beam along with the height of coal in the case.

When case was filled, each beater was lifted and remains on the top of its stroke to break away from coal bin.Beater is maintained in case beater falls after rise by folder deck thereon.

For making the effect effectively of this device, the friction factor between eccentric wheel and web is very big, so all will add the friction pad on two soffit of girders of beater.These pads are attrition components, therefore will regularly change.

Usually the step of installing or change these pads comprises I-shape beam is contained on the stand so that its soffit of girder is in a horizontal position, thereby needs beam is rotated repeatedly so that can alternately install or change pad to the surface of two soffit of girders.Because it is different to paste the temperature required with removing pad down, loads onto new pad after under therefore can not be earlier the pad of the abrasion on the soffit of girder one side being removed, and then another side is carried out same operation.Removing down, pad will carry out than pasting under the much higher temperature of pad, this means that each face all must make the beam cooling removing down the abrasion pad and load onto between the new pad, also mean when must limit exchange hot between the two sides when another side removes the pad of abrasion down.

And, even this process is earlier will one side and under the pad of another side removes, and then sticking new pad in one side and another side successively, beam still is subjected to unidirectional heating and cooling, thereby harmful even harmful to the normal running of beater distortion to the sticking Quality of finishing takes place.Thereby must make beam apply prestressing force in each position to prevent above-mentioned distortion.

Understand method more complicated and very time-consuming when carrying out that the past adopts easily.

The present invention seeks a kind of device so that the replacement process that is mounted to of this class friction pad is simplified.

For this reason, the purpose of this invention is to provide a kind of at the soffit of girder two mounted on surface or peel the device of pad, these operations all need to heat so that the Bond between beam and the pad is had an effect.

Should be appreciated that Fig. 1 is the simplified schematic diagram of apparatus of the present invention.Wherein the pending beam 1 of Xian Shiing is positioned on the horizontal stand 2, so its soffit of girder 1a is vertical.Support 2 is at two parallel to each other and and supports 2 also between the deck 3 and 4 of extension parallel to each other.The length of deck is not less than the length (approximately being several meters the order of magnitude) that is installed in the pad on the beam.

Support 2 comprises a fagging 5 that supports wheel or roller 6, and beam 1 can slide at wheel from vertical end of device.Support can be made up of a plurality of separate rectangular 2a, 2b, and rectangular is separated to allow the common indentation of auxiliary stand 8(by gap 7, is positioned at below the beam 1) vertically pass through.

Support 2 and deck 3 and 4 are supported by a unillustrated framework in Fig. 1.The deck drive unit is connected between deck and the framework deck being moved in opposite directions or be moved away from each other, thereby soffit of girder 1a is clipped between the deck, or is used for it is unclamped.Support 2 can with the framework relative fixed, and deck can be in support bracket fastened two side shiftings.Yet, in order to reduce the number of driving mechanism, preferably make deck 3 only drive deck 4 with the framework relative fixed, deck 4 can move along direction of arrow A shown in Figure 1.In this case, also removable the driving with deck 4 of support 2 shifted to deck 3.Support 2 is connected in the installation drawing of deck 4 and represents by the Flexible Connector 9 and 10 that is positioned between support and each deck, when deck moves on to a time-out, these devices are compressed, thereby make support 2 move half quantity that equates about and stroke 4 to deck 3, when deck is removed, these devices open once more, thereby make support 2 leave same distance and return the original place from deck 3.

Deck 3 and 4 respectively has a working surface 3a, 4a, they form a shoe separately in order to pad is pressed on the beam, this shoe can be by the heat-transfer arrangement heating that be positioned at every deck 3b and 4b place or cooling (water or the steam circuit adjacent with shoe 3a, 4a, resistance, the air draught loop ... Deng).

Advantageously, each deck 3 or 4 is made up of two-part, these two-part around with support on the axle 11 or 12 that extends in parallel of the direction of beam 1 hinged.Concerning deck 3, it is fixed frame 13a and deck 3 part 13b own that a part is arranged in these two-part.Concerning deck 4, the 14a of first portion is made up of a balladeur train that slides on the framework that is subjected to the actuator effect, and second portion 14b is made of the active part of deck.These hinging structures can make surperficial 3a and 4a be positioned at horizontal position, so that place pad and it is pressed on the beam.

At last, auxiliary stand 8 comprises two branch jaws (only showing 15 among the figure) at least, separately fork can be along the arrow B direction by vertical drive to hold beam 1 and it be lifted away from support 2.Each divides jaw 15 that a core 16 is arranged, core 16 comprises the device of holding beam, the y direction that this device can linger changes in the support arm inward turning, thereby in case after lifting beam, just might make its soffit of girder 1a be in arbitrary position in two possible horizontal positions, so just can touch the two sides of the soffit of girder easily, take off to remove bonding (heat treated is provided by deck 3 and 4) such as the pad of the abrasion that heat treated can be crossed.

Fig. 2 and Fig. 3 have shown the preferred embodiment of the device of schematically describing among Fig. 1.

Above-mentioned most of parts of having described can find in these two figure, and every identical part all adopts identical numbering among each figure.

But Fig. 2 can make deck 3 and 4 shift near mutually or remove and the mechanism of synchronous working when its articulating point rotates in order to show.

Number the framework of 20 indication devices, wherein a part is made up of the fixed support 13a of hinged deck 3 thereon.The sliding bottom of deck 4 (or balladeur train) 14a is connected on the bar of an actuator 21 (in fact, device comprises a plurality of along the isolated regularly actuator of deck 4).The a part of 14b of this of deck 4 is fixed on the gear 22, and gear 22 therewith rotates around axle 12.In the final stage of actuator 21 retractions, and in the initial period of its extension, gear 22 and tooth bar 23 concerted actions by frame supported.So just can understand when deck opens stroke and finishes or when the closed stroke of deck began, a part of 14b of this of deck 4 rotated around axle 12.Thereby deck 4 moves to the position (Fig. 3) that its surperficial 4a is in level from its surperficial 4a towards the position of beam 1 (Fig. 2).

By elasticity telescopic rod 24 with deck 3 and 4 connect together guaranteed deck 3 rotate driving (in fact, two bars 24 link together deck 3 and 4, and one at every end is outside the two ends of support 2) around pivot synchronously.Each deck 3 and 4 cranks arm 25,26.Cranking arm 25 is articulated on the bar 24 around axle 27, and axle 27 is by slider 28 supportings, and slider 28 slides and is subjected to the opposite effect power of spring 29 and 30 along bar 24.Crank arm and 26 be articulated in the end of bar 24 around axle 31.Axle 11,12,27 and 31 has been formed the tetragonal summit of a shape variable.Like this, from position shown in Figure 2, close in opposite directions mobile of deck makes axle 27 shift to the left side of figure, thereby makes deck 3 oblique its horizontal positions and be supported on the framework.Because slider 28 makes bar 24 with respect to 25 translations of cranking arm, deck continue close mutually mobile be still possible.

When deck opened (under the driving of actuator 21) action beginning, bar 24 slided with respect to slider 28, and slider 28 keeps static under spring 30 effects.In case spring 30 keeps balances with spring 29, promptly greatly about gear 22 during with tooth bar 23 engagements, cranking arm 26 begins rotation (and continue simultaneously to slide among the figure right-hand), makes deck 3 arrive position shown in Figure 3 around axle 11 rotations up to it.Spring 29 makes crank arm 26 the driving of 24 pairs on bar more flexible, also plays a part the buffering of exerting all one's strength when stroke finishes.Rightabout rotation can obtain by the stretching, extension of actuator 21.

This figure has also shown device 9 and 10, and they provide elasticity to connect between support 2 and deck 3 and 4, when deck is closed support are driven to deck 3, make support move apart deck 3 when deck opens.

Fig. 3 has shown a preferred embodiment of auxiliary stand 8.In this form, support 8 is fixed on the rotating deck 4, and when deck rotated, support 8 was lifted like this, thereby holds up beam 1 it is placed position shown in Figure 3.

In this position, be easy to touch the surface of soffit of girder 1a and utilize middle body 16, middle body 16 in minute jaw 15, to rotate so that the rotation of the direction of arrow shown in the C among the Liang Rutu.Very natural, device comprises support 8, and support 8 comprises at least along vertical two parts spaced apart from each other of beam.

Following the carrying out of operation of device:
