DE1071656B - Reversing device for the shut-off devices of regenerative ovens or the like. - Google Patents

Description

The main patent application relates to a reversing device for the shut-off devices of regenerative furnaces, Regenerative heaters or the like, in particular for regenerative coke oven batteries, with actuation of the pulling elements assigned to each group of shut-off elements by a pulling lever each, with during the successive reversal of the output gears up to the rotation of the respective reversal a group performing drive wheel are locked. ίο

According to the main patent application, the drive wheels are arranged on the common drive shaft designed as cam disks and act in the cam recess in both directions of movement against output pins each arranged on a pull lever that can be pivoted about a fixed pivot point or a role.

According to the main patent application, the cam disk shaft is also located in the area of a recess the pull lever, the size of the recess corresponding to the pivoting range of the pull lever.

The invention now relates to an improvement of the reversing device according to the main patent application; it consists in the fact that the end of the tension lever provided with the output pin .segment-like is formed, with a central output pin in the appropriate recess during the drive movement of a circular part and an output pin arranged on both sides in the recess of a Cam part of each drive wheel engages on both sides of the cam.

Such a design of the reversing device means that the drive shaft is outside the range the pull lever mounted, so that there is a simpler design for the pull lever.

The invention is illustrated in the drawing, for example.

Fig. 1 shows the design of the reversing device according to the invention in a side view;

Fig. 2 shows a front view of the reversing device;

Fig. 3 shows the pull lever with a drive wheel in the middle position of the reversing movement of a pull rod dar;

FIG. 4 shows the end position of the pull lever in the opposite end position shown in FIG.

Three output gears 2, 3, 4 are attached to the drive shaft 1. The drive shaft 1 is in bearings 5 a support frame 6 is suspended and is driven by a drive motor not shown in the drawing rotated during the change process.

The drive wheels 2, 3, 4 consist of a circular part 2a, 3a, 4a and a cam part 2b, 3b, 4b. In the circular part 2a, 3a, 4ο of the drive reversing device

wheels is a recess in the form of a tooth gap 7 is arranged. The cam part 2b, 3b, 4b has a recess 8 through which a cam 9 is formed. The flanks of the cam 9 are designed like a gear wheel at 9 a, 9 b , such that output rollers 10, 11, 12 of pull levers 13, 14, 15 roll on these surfaces during the drive movement as in a rack tooth system. The pull levers 13, 14, 15 designed as double levers are loosely mounted on an axle 16 in bearings 17 of the support frame 6. A pull rod 18, 19 engages each of the two arms of the pull lever, which are moved in opposite directions during the pivoting movement of the pull lever about the axis 16, levers not shown in the drawing, coupled to the pull rods, reversing shut-off devices.
The output rollers 10, 11, 12 of the pull levers 13, 14,

15 are mounted segment-like at the lower end of the tension lever that they mesh with the recesses of the drive wheels. The middle driven roller 12 lies in the area of the circular part 2a, 3a, 4a. The output rollers 10 and 11, on the other hand, are arranged on the pull levers 13, 14, 15 in the region of the cam part 2b, 3b, 4b of the drive wheels.

When the drive shaft 1 rotates in the direction of the arrow 20, the cam surface 9b of the cam 9, for example of the drive wheel 2, first strikes the driven roller 10 in the position shown in FIG. 1.

As a result, the pull lever 13 is about its loose axis

16 rotated, the output roller 10 rolling on the cam surface 9 b. The output

roller 12, which initially unrolls on the outer surface of the circular part 2a of the drive wheel, into the tooth gap-shaped recess 7, as can be seen from FIG. When the shaft 1 continues to rotate in the direction of the arrow 20, the driven roller 12 again passes from the area of the tooth gap 7 onto the outer surface of the circular part 2a , as can be seen from FIG. The driven roller 11 has entered the recess 8 in front of the cam surface 9σ of the cam 9. In a further rotation of the shaft 1, the driven roller 12 now runs on the circumferential surface of the circular portion 2a and the driven roller 11 in the recess 8, so that the tension lever 13 is locked against further movement. In the position shown in FIG. 4, the cam 9 'of the drive wheel 4, shown in dashed lines in FIG. 1 reaches the position that was previously assumed by the cam 9 of the drive wheel 2 in Fig. 1, and the cam 9 ″ of the drive wheel 3, also shown in dashed lines, has that shown in FIG Position of the cam 9 'of the drive wheel 4 is reached. The cam 9 'of the drive pulley 4 now causes a pivoting movement of the associated one in the same way Pull lever 15, whereupon it is also blocked after reaching its end position, as described and the pivoting movement of the pull lever 14 by means of the associated cam 9 ″ and the recess 8, the drive pulley 3 takes place in the same way. The opposite takes place in a corresponding manner Movement from the position shown in FIG. 4 to the position shown in FIG. To an unauthorized To avoid adjustment of a single pull lever, the end position of each pull lever is through to the Support frame 6 attached stops 22, 23 limited. This end position can be adjusted by adjusting screws 24 will.
