Abstract

The brake arrangement for a transport train of a monorail comprises cylindrical plungers (21) arranged on each side of a I-shaped travel rail (1). The web-side end sections of the plungers (21) are flattened off at the top and at the bottom and thus form tongues (25) which engage in recesses (28), matched thereto, of brake lining carriers (23). The connection of the plungers (21) to the brake lining carriers (23) is made by means of connecting bolts (36) which can be displaced transversely in holes (35) of the tongues (25). The plungers (21) and the brake lining carriers (23) are elastically supported with respect to one another. These elastic supports permit relative displacements of the plungers (21) with respect to the brake lining carriers (23) in cases where the travel rail (1) extends at an angle with respect to the longitudinal axes (46) of the plungers (21) which differs from 90 DEG . The elastic supports can comprise rings which surround the connection bolts (36) and are supported on the walls of the holes (35) in the tongues (25). Elastic buffers between the end sides of the tongues (25) and the floors of the recesses (28) are also conceivable. <IMAGE>

BRAKE DEVICE

The invention relates to a single-rail rail transport train braking device according to the characteristics in the parent term of claim 1.

Such a braking device is preferably used in the case of traveling transport trains in the case of mines excavation, P r e d v i d e n a is on v 1 e C n i h vehicles and also in k. 1 j u C e n a v so-called C k e braking m ay be directly adapted to towed vehicles or spaced apart.

As a rule, the braking device comprises a cylinder for moving the brakes that is strong, for example, extending between two moving levers transversely to the running track of the transport train. The brake offset cylinder can be operated with a hydraulic pressure medium through which the brake pads move away from the track door against the back force of the mechanical spring package, which tends to push the brake pads against the door. In the event of a failure of the pressure medium, the braking device is stopped and the transport train is stopped.

The brake pads are riveted on the brake lining brackets, which are individually coupled to substantially perpendicularly shaped cylindrically shaped hand rails perpendicular to the carriageway door. The rods are connected to their other ends via a lever with a brake-cylinder,

The connection of the physicians to the brake lining beams is such that k

-2 The reverse ends of the pistons are gripped into properly shaped recesses on the brake lining brackets with radial clearance and are fixed in the recesses by connecting bolts, such as massive tensioning pins. The forearms of the gunmen are lightly rounded. They reach the bottom of the recesses to the supported position.

In the practical application of the known brake device, it has been shown here and there that the brackets with the a v o r n i h brake lining are separated from the handbrakes in such a way that the function of the brake device is interrupted. This is due to the absence of tensioning pins in conjunction with the ends of the jibs that engage the recesses of the brake lining mounts. namely, if the braking occurs during operation in a position where the longitudinal axes of the side arms do not extend at an angle of approximately 90 ° to the longitudinal direction of the track, then the brake lining beams are placed obliquely on the side arms, thereby exposing the massive tensioning pins to the massive tensioning pins. such high loads that they are cut off. If, after braking the brake lining, it is again moved away from the neck, the brake lining brackets together with the brake lining may be separated from the handbrakes so that the brake device is then unusable.

Based on the features described in the parent term of claim 1, the basis of the invention is to improve the braking device in such a way that the loss of the brake lining brackets with the brake lining can be ruled out.

The solution of this task according to the invention can be seen from the characteristics indicated in the designation of claim 1.

After that, the ends of the thrusters, which engage in the recesses of the brake lining brackets, are flattened on the upper and lower sides, so that stable tongues are formed which have parallel upper and lower horizontal sliding plates and convexly rounded lateral surfaces.

The 3 sliding surfaces have counter-slots in the recesses of the brake lining beams, which leads to the result that they do not form forced guides that prevent the ends of the arms, which are engaging in the recesses, and thus the resulting transverse forces.

In conjunction with these forced rails, the rails are limited elastically supported against the horizontal carrier brackets, but if the track is now rotated at an angle to the longitudinal eight bars other than SO ° when braking, the brake liners may be adapted to the travel course when braking. the tracks now move to a limited extent against the d handles. Mounting bolts that are only fixed in the brake lining brackets. However, through holes in the tongues of the leaflets, they are guided with such radial clearance that a relative displacement of the beams from the a v o r n i h lining to the tongues can be ensured without the risk of breakage or breakage of the connecting bolts. The brake lining mounts therefore remain connected to the rails and the braking device retains its function. In this way, operational safety is significantly increased, especially when using the braking device of the invention in transport trains for mine excavation. Anti-mechanical spring counterparts can be formed with a hydraulic or pneumatic pressure medium or with an electrically adjustable adjusting unit.

A useful embodiment of the invention is in the features of claim 2. In this case, elastic support is provided between the rods and the brake lining holders approximately in the mid-range of the tongue thicknesses, between the connecting pins on one side and the hole walls in the tongues on the other.

In this connection, a further development step in claim 3 is considered expedient. In this connection, the connecting pins in the middle thickness range of the tongues are provided with constrictions, for example in the form of circular grooves along the circumferential side. Rubber or plastic rings are inserted into these circular grooves. The elastically flexible properties of these materials are intended to guarantee the necessary distance between the d r o C n i k i and the brake lining brackets, as well as to ensure that, when the bracket carriers are moved relative to the d r o c n i k o m, the connecting pins in the tongue holes can be moved transversely to the required dimension.

if the elastic supports are made with the aforementioned rings, it is advantageous, in accordance with the features of claim 4, to provide the binders with the ends at the other end with c i1i n d r i C n i m i heads. Between the heads, the n a h a j a j o po ρ r e m e r u is thinner longitudinal sections z to arbitrarily size k o r a z d a 1 j o to the walls i z v r t i n. The design of the holes of the brake lining brackets, which "match the drill bores with the matching inner threads, is based on the actual condition that the brake lining brackets can be used in this direction as well as in the other direction in which it is shown. as a useful form of trapezoidal brake pads. In this case, the brake lining brackets can be rotated 180 ° vertically and the mounting bolts are screwed in on both sides, especially from above. The diameter of the cylindrical heads is then set to the diameter of the core of the threaded holes. In addition, the recesses are useful in threaded heads, but not the case for multi-edge screwdrivers. The warheads may also be fitted with flanges that determine the depth u in i t j a.

A further embodiment of the basic thought of the invention is indicated in the features of claim 5. In this case, the elastic supports are formed by bumpers included between the tongues and the brake pad supports. Preferably, tl bumpers are arranged in planes spaced apart from planes extending through the longitudinal axes of the bars. It is advantageous to have eccentrically mounted bumper between each brake lining carrier and each sidewall. These may be T-shaped bumpers that extend with their stems from the brake lining brackets to recesses and rely on

-5Langing pages of languages. In this way, the brake lining surfaces are positioned at an angle to the track door, which results in traces of C having t i r n i c a and no running track can run smoothly. This version is especially suitable for those 1 C vehicles or brake cats in which the braking device is in the direction of travel in front of the drive and wheels, which return to prey axles or just in front of the guide 1 when 1 turn 11 around it. na in pi C nihosi. In the other direction of travel j o o k: o 1 i: s i, which are taken over

P a g e or P roductor 1 Concentrating sequentially the following rails in lateral displacement. In order to be traveled unevenness in Nemo before you ru in I vobmo C contacts by the two rails rolling track ^- but without problems, there are sufficient customary bevel in the direction of travel of the front sides of the brake linings.

When using the bumpers described above, it is advantageous to use the features of claim 6. In this case, the special mounting pins are also not used to assemble the frames with the brake lining brackets, but rather the usual massive tension pins. These are fixed in the brake lining brackets and run through the holes in the tongues of the lugs with radial clearance so that the desired relative movements of the lining lugs against the luggage can be carried out under different operating positions, without massive tensioning of 1 C and exposed to special shear. loads

Particularly in the form of a rib formed on the front of the tongues in the middle of the patent pendulum 7, in conjunction with the vertical grooves in the bottom of the recesses, the advantage is that the holes for the vertical tongue bores can be sufficiently dimensioned without weakening the tongues. In addition, it is advantageous in this respect that the areas of the fronts of the tongues, in addition to the ribs in the areas of the bottom, can reach the vertical grooves in addition to the vertical grooves. Therefore, the specific surface pressures with sufficient braking force are low.

-6To allow the brake pads to move relative to the drone without impermissibly high clearance, the features of claim 8 are provided. In this way, lateral avoidance zones which are on the convex sides of the booms are created on the brake pads.

Finally, we see a further feature of the invention in the features of claim 9. This blocking of the position of the shutters in the running position proves particularly useful in the replacement of the brake pads for wear. They allow the brake pads to be exchanged at each track location. For this purpose, the brake lining beams are moved to the driving position. This means that the brake linings are at a distance to the neck. The slats are then provided, for example, with transverse bores located on the side of the slider guides facing away from the door of the track. These cross-holes can be locked with locking bolts which, in the event of a failure of the hydraulic power supply, ensure that the springs do not press the brake pads accidentally against the neck and thus expose the installers to the imminent risk of damage.

The invention is further explained in the following, based on the embodiments presented in the drawings. The drawings show:

On the track 1, a transport train consisting of a traction machine 4 with drive units »from two driver's cabs 5 may move and not in more detail. The driver's cabs 5 are located at each end of the transport train.

Traction vehicle 4, auxiliary units 6, 7 and one of the cabins 5 coupled thereto, shall be equipped with braking devices 8, which shall be designed in such a way that the brake linings 9 can be more clearly identified in Figures 3, 5 to 7 and P to 11. they move away

This presses the brake pads 9 over the movable levers 12 and through them through the joints 20 of the connected handbrakes 21 of the track 10 of the track 1. The handles 21 can be forced to move in the cylindrical guides 22 transversely to the door 10 (see also drawings 3, 5 to 7 and 9 to 11).

The brackets 23 which are horizontally longitudinally p r e r e with u approximately conical, are connected in the brake lining brackets 23 when v i c a m i 24 (Figures 4 and 8). In practice, it is shown a1 that the trapezoidal embodiment of the brake lining brackets 23 in accordance with drawings 4 and 8 and the corresponding configuration of the brake lining 9 are useful with respect to wear, with these brake lining brackets 23 in both driving directions being displaced each time by 130 ° in the vertical plane.

In Figures 3, 5 to 7 and 9 to 11, we can recognize that the ends of the otherwise cylindrical d r o C n i k o v 21, which are facing the door 10 of the track 1, are on the top and bottom s p 1 o 5 c e n i. To this at C and are formed tongues 25, which are not two two not in common ρ ara 1 e 1 but extending horizontal sliding surface 26 and convexly curved lateral boundary surfaces 27. These languages 25 grab, as shown in particular in Figures 4 to 8, in recesses 28 adapted to: tongue configuration 25 in the brake lining supports 2 3. This means that the brake lining carriers 23 have recesses 2 8 with horizontally parallel counter-surfaces 2 9 and concave side surfaces 30.

In the embodiment of drawings 3 to 6, identical threaded holes 33 are inserted in the areas 32 and 1 which extend above and below the recesses 28 in the brake lining brackets 23. In addition, these threaded holes 33 end in C cylindrical sections 34 at the end. pages (Figure 4). In accordance with the diameter of the threaded holes 33, apertures 35 are provided in the tongues 25 of the spacers 21. 2 a The connecting pins 36, each having a threaded head 37 and a cylindrical head at each end, are used to connect the tongues 25 to the brake lining brackets 23. 38.

As long as the track 1 is approximately at right angles to the longitudinal axes 16 of the arms 21 (drawings 3 and 5), the brake linings 9 are pressed flat against the door 10 of the track 1 when braking, but if the track is properly shown in figure 6 at an angle to the longitudinal axes 46 of the diaphragms 21, which is 90 ° different from each other, it is then possible, at the beginning of the braking, to allow the brake lining brackets 23 to move purposefully to the recesses 28

In this way (Figure 10), the brake lining brackets 23 in the driving position retain a kind of slider 1 relative to the door 10 of the track 1, leading to the result that it can be transported without delay in the area In addition, such an embodiment also permits a move: of the brake lining brackets 23 relative to the hoops 21 according to Figure 11, if the brake force is activated and the running track 1 is placed obliquely on the longitudinal axes 46 of the hoops 21 The massive tensioning pins 47 may then be transversely displaced in the holes 49 of the tongue 25 without being subjected to shear.

Figures 2 and 7, and in particular from Figure 7, further show that the arms 21 are provided with transverse holes 51 in the area adjacent to the joints 20 between the arms 21 and the movable levers 12. These transverse holes 51 serve to insert bolts for blocking in cases where, according to Figure 2, the brake pads 9 are lifted from the neck 10 of the track 1 and must
