Description

[Detailed description of the invention] push rod locking device The present invention is a tamper for producing a compacted coal cake with a ramming rod locking device. The machine includes a ramming rod locking device disposed above the lifting device and a wafer of the ramming rod. It has clamp members placed on both sides of the block, and this clamp member allows The web of rods in each case closes the tamping process at the upper end position and its termination Concerning tamping machines adapted to be post-tightened.

In order to improve the quality of coke, certain coke grades are It is compacted in a compaction mold before being charged into the coke oven chamber. Then all The coal cake itself is charged into an empty coke oven, and especially during this process , a plunger arranged to fall freely is fixed at the upper end position.

Take advantage of this opportunity to make sure that the push rod does not get in the way when transferring the coke cake. In order to can. Until now, this clamp and stop was applied to eccentrically supported segment cars. This is realized by means of clamping wedges or clamping wedges, these are actuated by a working cylinder or pivotable. (German Publication No. 3445068.8), thrust In the case of eccentrically mounted segment cars used as bar locking devices, line contact is What happens is particularly disadvantageous. This is because the groove is a friction lining. This is because it occurs in These grooves are caused by a very flat surface during line contact; And because the position during each clamping process is different, it may cause long-term crank formation. It is et al.

This results in premature destruction of the lining, a relatively short service life and a relatively high maintenance Other drawbacks arise, such as cost. Clamp bar used as a locking device Locking devices that are actuated by cylinders require a large number of actuating cylinders; The technical and mechanical costs are very high.

The present invention is simple in construction and has a profile that guarantees a specific surface pressure that is uniform and as small as possible. The basis of the task is to create a locking device for a spindle.

According to the present invention, this problem is solved because the clamp member is formed as a clamp plate, and the clamp member is formed as a clamp plate. Each clamp plate is connected to a rotatable shaft via a parallelogram linkage. It is solved by being possible.

This special configuration of the plunger locking device eliminates the need for expensive adjustment mechanisms. , the clamping plates can each be pressed parallel to the web of the stabbing rod. that On the contrary, thanks to the parallelogram linkage, the plate can already be positioned at the respective end position. It is guided optimally to the web each time during the course of the movement, thus ensuring an even surface pressure. It is ensured that the The entire clamp plate or placed on both sides of the web The clamping plates are pressed simultaneously and evenly, so the clamping or stopping process is The direction of the lines of force is distributed over the entire clamp plate surface. Moreover, very useful This results in a small specific surface pressure that is advantageous. Additionally, damage occurs due to the formation of grooves and cracks. As a result, a high useful life is achieved. However, especially small Due to the constant surface pressure, even a thrust rod with a high self-weight can be used without problems. clamp The plates are swung from the clamped position to the uncoupled position via their respective rotatable shafts, and It is advantageous to travel only short distances when .

According to the advantageous design of the invention, the clamping plate can be rhythmically and permanently connected to the plunger. It can come into contact with the web. Via the axis, the respective desired and necessary movement course is This can be accomplished without compromising the effectiveness of the locking device. In this case, there is an advantageous reliable ramp action and uniformity between the plunger and the clamping plate. A distributed surface pressure is obtained.

To ensure optimal uniform operation, the axes of the plunger locking devices share a common oscillating drive. Make it last. In this case, this oscillating drive unit is displaced obliquely to the axis. This cylinder is operated by a swinging lever arranged oppositely. It is useful for the shaft to be connected to the shaft. In addition, a particularly simple and space-saving drive The dynamic concept must be emphasized.

This also means that the plunger locking devices arranged side by side are on a common shaft and Optimized by combining into a unit with several drive units. Connection with shaft Both clamping plates can be individually absolutely uniformly facing each other or moving away from each other during each course of movement It is ensured that you exercise as much as possible.

As already mentioned, the individual clamping plates are each placed parallel to the web of the stabbing rod. be done. The contact surface of the clamp plate should run parallel to the vertical axis of each plunger. The objective is to form a Therefore, the wear that occurs on the friction lining can be compensated, and then Regardless of that, it is certain that the lamp will always be provided.

Furthermore, the lamp is always guaranteed to be compensated. This is because the contact surface is on the clamp plate. This is because it is formed by an integrally arranged replaceably formed wear plate. Ru.

Parallel rocking of the individual clamp plates is achieved by parallelogram linkage. According to the invention, the parallelogram linkage is constructed by means of upper parallel bars supported on a framework. and by a lower parallel bar displaced to swing freely about its axis. It is formed.

Special Table Sen1-501712 (3) According to this purposeful construction, each clamping plate is connected to a lower parallel bar. It is held securely and swingably, with the actual displacement being ensured. The upper parallel rods provided guide the clamping plate. Then each parallel bar is , consisting of a lever and a connecting rod which are pivotably or rotatably held at two points.

In order to set the travel of the clamp plate and to avoid swinging further ( In addition, the lower parallel bar is equipped with a driving member that limits the absolute lower end position of the clamp plate. will be established. This end position is suitable for example for sinking the ramming rod to the point of critical wear. The shafts are rotated relative to each other and are then clamped by a driving member acting on the parallel bar below. The plate is separated from the lining of the stabbing rod.

In particular, the rapid rhythmic ramp and separation of the clamp plate centrifuges this clamp plate. According to the invention, this centrifugal force effect can be overcome by adding a damping element to the lower parallel bar. It is removed by attaching it. In that case, this damping element is free to swing outwards. It is advisable to arrange the clamp plate in such a way that it limits the upper position of the clamp plate. The resulting clamping plate is effectively limited depending on the stroke of the lifting device. In that case, The row member is lifted to the upper end position by the clamp plate through opposing rotations of the shaft. It is for good purpose that it be formed like this.

The invention ensures that the clamp plate abuts parallel to the web of the plunger at each position. It stands out in particular because of the fact that This ensures that during the clamping or stopping process Advantageously, the directions of the lines of force are distributed over the entire clamping plate surface. Furthermore, one On the one hand, a very advantageous small specific surface pressure is obtained, and on the other hand, the entire surface of the clamping plate is Even pressure is applied throughout. In an optimal operating sequence, relatively low maintenance costs and A relatively long useful life is achieved. In addition, the relatively small surface pressure allows the plunger to Weight increases are possible immediately.

Further details and advantages of the subject matter of the invention can be found in the drawings 0, which can be obtained from the following description of the attached drawings. A particularly advantageous embodiment is shown together with the necessary details and individual parts thereof. .

FIG. 1 shows the tamping machine in partial side view, and FIG. 2 shows it in front view. , the plunger locking device is generally indicated at 1, while the protrusion that raises the plunger foot 3 is shown in FIG. A lifting disk 5 for lifting the pusher rod is arranged below the pusher locking device l. Ru. These lifting discs 5 cover the friction lining 6 of the ram 4 or the wafer of the ram 4. The friction lining 6 of the tab 16 is pressed. Similarly, a push rod lock covered with wear plate 7 The clamping plate 8 of the locking device 1 also presses against these friction linings 6 on the web 16. W! It is separated from the rubbing lining. child For this purpose, a rotatable shaft 9 is useful, as will be explained below.

The clamp plate 8 is clamped together with the wear plate 7 via the lower parallel bar 10 and the upper parallel bar 12. guided parallel to the web 16 and depending on which direction the shaft 9 is rotated, Pressed or lifted evenly against the web. At that time, the downward parallel The bar 10 is displaced to swing freely about the axis 9, while the upper parallel bar 1 2 is held in a swinging manner by the frame.

Via the entraining element 11, the lower parallel bar 10 and thus the clamping plate 8 are connected to the tamping bar. 4 from the friction lining 6 or vice versa.

In addition, a tamping type is shown in Figure 2 with the symbol 2, and this tamping type is In the illustrated embodiment, the surface is filled with compressed coke grade 21. , coke coal 21 can be charged into the coke oven.

Figures 3 and 4 show a push-rod lock that is sometimes closed and sometimes open. A device 1 is shown in which the parallel guides of the clamping plate 8 are parallelogram linkages. Revealed via 10.12.

5 and 6 clarify the location and formation of the cylinder 14. FIG. Figure 5 is , shows the same cylinder when the locking device 1 is opened, and FIG. 6 shows the locking device R. 1 is closed, when the swing lever 13 or 13' respectively They are swung while facing each other. When the push rod locking device 1 is opened and closed , the cylinder 140 rotation and vertical movement are vertically guided sliding blocks This is compensated for by displacing the cylinder by the same distance at 22.

The rotation of both axes 9, 9' is caused by a parallel cylinder 14 arranged obliquely to the wheels. This cylinder is used here as the swing drive unit 18. and is connected to the shaft 9.9' via a swinging lever 13.13' arranged oppositely. ing. At 17 the flange of the plunger 4 is shown and at 19 the friction lining 6 an abutment guided and held in such a way that it runs exactly parallel to or to the web 16; side is shown.

Here, below Parallel bars 1O110' are centered on parallel axes 9.9' arranged on both sides of the push rod 4. It can be freely swung as it is. During the clamping process - lifting the push rod 4 Then, these axes 9.9' are rotated with respect to each other, with the clamping plate 8.8' being aligned with the parallelogram. Guided through form linkages 10.12 and 10.12', The web 16 abuts the friction lining 6 on both sides. Corresponding to the stroke of the elevating disk 5, A rhythmic separation and clamping takes place until the plunger 4 reaches its upper position. child When separated from the rhythmic ramp, a centrifugal force effect acts on the clamp plate 8.8'. However, this is eliminated by the damping elements 15,15'. This type of holding After finishing the lifting, the thrusting should be done to avoid interference when pushing the coal cake. The rod 4 is brought into the position shown in FIG. It is stopped by a locking device l. Now the coal cake or coke grade 21 is punched. It can be slid out of the tamping mold 2 in a hardened state, and the tamping rod 4 blocks it. Not at all.

After extruding the coke grade 21 from the tamping die 2, release the clamp plate 8.8'. In order to lower the plunger 4, the shafts 9,9' are rotated relative to each other, with the driving member 1 1.11' to the lower parallel bar 10.10' and thus the clamping plate 8.8'. It is separated from the friction lining 6 of the plunger. A new tamping process has now begun. The coke grade 21 is then compacted in the tamping mold 2 into a coal cake.
