Description

Die Erfindung bezieht sich auf Selbstentlader mit einem wahlweise durch Druckluft oder von Hand kippbaren Wagenkasten, der durch ein Kurbelgetriebe mit dem Untergestell in Verbindung steht. Die Erfindung besteht in erster Linie darin, daß eine Verriegelungswelle ein das Kurbelgetriebe verriegelndes Sperrorgan sowie Anschläge trägt, die sowohl mit einem Gliede des die Druck-ίο luft steuernden Organs als auch mit einem Anschlage des die Entladung des Selbstentladers von Hand vermittelnden Organs zusammenzuarbeiten vermögen.The invention relates to self-unloaders with an optional compressed air or manually tiltable car body that is connected to the underframe by means of a crank mechanism communicates. The invention consists primarily in that a locking shaft carries a locking member locking the crank mechanism as well as stops that are both connected to a member of the pressure ίο air-controlling organ as well as with a stop of the discharge of the self-discharger able to cooperate with the manual mediating body.

Der Wagenkasten A des Selbstentladers ist auf dem Untergestell B unter Vermittlung von Kippzapfen 6¹ (Abb. 1) schwingbar gelagert. Zwischen dem Wagenkasten A und dem Untergestell ist mindestens ein Kurbelgetriebe eingeschaltet, das aus einem gelenkig mit dem Wagenkasten verbundenen Lenker C und einer oder mehreren (s. Abb. 2) Kurbeln D besteht. Jede der Kurbeln D ist undrehbar mit einer Welle £ verbunden und trägt einen Fortsatz d¹ mit einem seitlichen Zapfen d², der sich in der Entladestellung des Getriebes (Abb. 5) gegen den Lenker C stützt. Auf der Welle E sitzt eine weitere Kurbel F₁ an der die Kolbenstange g¹ eines Druckluftzylinders G angreift. Die Kurbel F sitzt lose drehbar auf der Welle E und trägt in bekannter Weise eine Kuppelscheibe f¹ (Abb. 2), die mit einer zweiten, auf einem Vierkant e¹ der Welle E verschiebbaren und von Hand einstellbaren Kuppelscheibe/² in Eingriff gebracht werden kann. Der Zylinder G ist mittels hohler Zapfen g² am Untergestell des Wagens schwingbar gelagert. Die Hohlizapf en g² sind an eine Druckluftleitung g³ (Abb. 2) angeschlossen, in die ein Absperrventil g·⁴ eingeschaltet ist. Die Spindelii dieses Ventils trägt einen Handhebel h^l und einen Steuernocken h², der dazu bestimmt ist, mit einem auf einer Verriegelungswelle K befestigten Daumen k¹ zusammenzuarbeiten. Mit der Welle K ist ferner eine Sperrklinke £³ undrehbar verbunden, die in der Ladestellung (Abb. 1 und 2) über den Gelenkzapfen d³ des Kurbelgetriebes C₁ D greift. Auf der Welle K ist schließlich noch ein Daumen k^z vorgesehen, der in der Bahn eines an einem Gehäuse L vorgesehenen Anschlages V- liegt. In dem auf der Welle E lose drehbaren Gehäuse L ist eine zum Antrieb des Getriebes von Hand bestimmte Stange M verschiebbar gelagert. Diese Stange trägt an. ihrem einen freien Ende einen seitlichen Zapfen«¹ (Abb. 1), der in der Ladestellung in einer am Untergestell befestigten Pfanne b² ruht. Das Gehäuse L trägt in einem Ansätze I² eine doppelte Sperrklinke N, die mit einem starr mit der Welle E verbundenen Sperrade P (Abb. 7 bis 9) in Eingriff gebracht werden kann.The car body A of the self-unloader is pivotably mounted on the underframe B by means of pivot pins 6 ¹ (Fig. 1). At least one crank mechanism is connected between the car body A and the subframe, which consists of a link C and one or more (see Fig. 2) cranks D that are articulated to the car body. Each of the cranks D is non-rotatably connected to a shaft £ and carries an extension d ¹ with a lateral pin d ² , which is supported against the handlebar C in the unloading position of the transmission (Fig. 5). On the shaft E there is another crank F ₁ on which the piston rod g ^{1 of} a compressed air cylinder G engages. The crank F sits loosely rotatable on the shaft E and carries in a known manner a coupling disk f ¹ (Fig. 2), which is brought into engagement with a second ^{coupling disk / 2} , which is slidable on a square e ^{1 of} the shaft E and can be adjusted by hand can. The cylinder G is pivotably mounted on the underframe of the car by means of hollow pins g ^2. The hollow pins g ² are connected to a compressed air line g ³ (Fig. 2) into which a shut-off valve g · ^{4 is} switched on. The Spindelii this valve carries a hand lever h ^l and h ² a control cam, which is intended to cooperate with a locking shaft fastened to a K ¹ k thumb together. A pawl £ ³ is also non-rotatably connected to the shaft K and engages in the loading position (Figs. 1 and 2) via the pivot pin d ^{3 of} the crank mechanism C ₁ D. Finally, a thumb k ^z , which lies in the path of a stop V- provided on a housing L, is also provided on the shaft K. In the housing L, which is loosely rotatable on the shaft E , a rod M intended for driving the gear mechanism is slidably mounted. This pole carries on. One of its free ends has a lateral pin « ¹ (Fig. 1), which rests in the loading position in a pan b ^{2 attached to the underframe.} The housing L carries a double pawl N in an approach I ² , which can be brought into engagement with a pawl P (Figs. 7 to 9) rigidly connected to the shaft E.

Claims

When unloading are tilted by means of compressed air, the hand lever h1 is first moved from its rest position I to position II according to FIG. 3. The cam h2 engages with the thumb k1 of the shaft K and swings the pawl ks into a position in which it releases the pivot pin d3 of the crank mechanism C, D. The transmission is then unlocked. The hand lever is then moved further into position III according to Fig. 4. With this movement, the valve g4 is opened, the compressed air flows into the cylinder G, and the piston rod g1 turns the crank D clockwise so that the car body A is raised. Approximately in the position of the parts according to Fig. 4, the car body begins to tilt under the effect of its own weight. The lever / ι1 is turned further to the position IV according to Fig. 5, in which the valve g · 4 is closed again. As soon as the transmission g \ F has reached its dead center position on the way from Fig. 4 to Fig. 5, the oscillating cylinder G reverses and the compressed air flows from one side of the cylinder to the other. Meanwhile, the car body A continues to tip and compress the air in the cylinder G until the car body has reached its unloading position. In this position, the pin d2 rests under the action of the compressed air against the handlebar C and prevents the crank mechanism, which has exceeded its dead position by a small amount in the unloading position. When the box A is returned, the lever h1 is swung back again; on path III-II it then opens valve g4, and the compressed air is fed back to the piston side that was first loaded, so that crank D is now turned in the opposite direction to the clockwise direction of rotation (Fig. 6). In the dead position of the gearing g1, F, the compressed air is reversed again by the cylinder G1 so that the crank gearing is swung back into its initial position. On the way back of the hand lever h1 to the position I, the cam h2 releases the thumb k1 so that the pawl k3 can also fall back into its locking position. When unloading the car by hand, the coupling f1, f2 is first released and the rod M is pulled out sideways until its pin m1 hits the housing L. The link M, L is then rotated downwards, the stop P- hits against the thumb kz and thereby brings the pawl k3 except a handle with the pin d3; at the same time the pawl N comes into engagement with the ratchet P (Fig. 7). The car body is then tilted by lifting the rod M. As soon as the car body begins to tilt automatically under the effect of its own weight, the ratchet wheel P leads the pawl N so that the further tilting movement has no effect on the rod M. In the unloading position, the pin d2 meets the link C again and locks the gear. When returning the car body, the pawl N is thrown and the rod M swung back. At the end of the movement, the stop Z1 hits the thumb k2 again and thereby lifts the pawl k3 again; immediately afterwards he releases it again so that it can fall back into the locked position. During the unloading movement, the pawl k "was held in its position by the thumb k1 and the cam h2 (Fig. 9); in the last part of the return movement of the car body, this support is provided by the pin ds on which the nose of the pawl k3 slides, repealed again (Fig. 10).
