Abstract

U-shaped shoes, placed over each arm of the fork frame, slide upon application of a load. Expansion measuring strip cells are installed between the fork frame and the shoes on top. These measuring cells (2) are fixed to the shoes (6) by a coupling pliable on all sides, forming a so-called diabolo coupling (5). The latter consists of plane-parallel, pref. circular surfaces (7a, 7b) joined by a reduced surface area section formed by a recess (10). The smallest dia. of the latter is matched to the load to be transferred. ADVANTAGE - Good measurement value transfer free from cross:-sectional forces.

Description

Die Erfindung betrifft eine Meßvorrichtung für Gabelhubwagen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a measuring device for pallet trucks according to the preamble of claim 1.

Als Meßvorrichtungen zur Bestimmung der Lastgröße einer auf beiden Gabelschuhen ruhenden Last sind Vorrichtungen bekannt, die mit Hilfe von DMS-Meßaufnehmern, die zwischen Gabelschuh und Gabelrahmen einge­ baut sind, die zu messende Lastgröße erfassen und mit Hilfe eines Meß­ gerätes zur Anzeige bringen.As measuring devices for determining the load size one on both Fork shoes resting load devices are known to help of strain gauges inserted between fork shoe and fork frame are built, record the load size to be measured and with the help of a measurement display the device.

Die bekannten Vorrichtungen zeichnen sich dadurch aus, daß die Verbind­ ung zwischen Meßaufnehmern und Gabelschuh lose oder fest ist.The known devices are characterized in that the connection between the sensor and fork shoe is loose or tight.

Die losen Verbindungen leiten zwar die Last über den Gabelschuh quer­ kraftfrei in den Meßaufnehmer, was gute Meßergebnisse zur Folge hat. Die Nachteile dieser Ausführung sind sehr hoher Verschleiß und er­ schwerte Handhabung.The loose connections conduct the load across the fork shoe force-free in the sensor, which results in good measurement results. The disadvantages of this design are very high wear and tear difficult handling.

Die festen Verbindungen dieser Art haben zwar keinen Verschleiß und auch eine gute Handhabung, aber der Nachteil liegt in der weniger guten Meßwertübertragung durch Querkrafteinflüsse.The fixed connections of this type have no wear and tear also good handling, but the disadvantage is the less good one Measured value transmission due to shear forces.

Aufgabe der vorliegenden Erfindung ist es daher, eine Meßvorrichtung zu schaffen, die diesen Nachteil nicht besitzt und trotz fester Verbindung zwischen Meßaufnehmer und Gabelschuh eine querkraftfreie Meßwertüber­ tragung ermöglicht.The object of the present invention is therefore to provide a measuring device create that does not have this disadvantage and despite a firm connection between the sensor and the fork shoe carrying allows.

Gelöst wird diese Aufgabe dadurch, daß die DMS-Meßaufnehmer mit den U-förmigen Schuhen über eine, nach allen Seiten nachgiebige Verbindung fest verbunden sind.This task is solved in that the strain gauge sensors with the U-shaped shoes over a flexible connection on all sides are firmly connected.

Diese Verbindung soll eine sogenannte Diabolo-Verbindung sein.This connection should be a so-called diabolo connection.

Die Diabolo-Verbindung besteht aus planparallelen, vorzugsweise Kreis­ flächen, die über eine Einschnürung verbunden sind.The diabolo connection consists of plane-parallel, preferably a circle areas that are connected by a constriction.

Der kleinste Durchmesser dieser Einschnürung wird auf die zu übertra­ gende Belastungsanforderung abgestimmt.The smallest diameter of this constriction is transferred to the matched load requirement.

Die so festgestellten Meßwerte werden über ein Meßgerät angezeigt.The measured values determined in this way are displayed on a measuring device.

Fig. 1 zeigt einen in Seitenansicht dargestellten Gabelhubwagen mit Grundrahmen und Fahrgestell 1, DMS-Meßaufnehmer 2, feste Diabolo-Ver­ bindung 5 und U-förmigem Gabelschuh 6. Fig. 1 shows a pallet truck shown in side view with base frame and chassis 1 , strain gauge sensor 2 , fixed diabolo-Ver connection 5 and U-shaped fork shoe 6th

Fig. 2 zeigt den Ausschnitt einer Meßstelle in unbelastetem Zustand mit Grundrahmen und Fahrgestell 1 und aufgeschraubtem DMS-Meßaufnehmer 2, der mit zwei Befestigungsschrauben 3a und 3b gehalten wird. Das durch DMS 4 gemessene Signal wird über die feste Diabolo-Verbindung 5 über die Gabelschuhe 6 von der Last erzeugt. Fig. 2 shows the section of a measuring point in the unloaded state with base frame and chassis 1 and screwed-on strain gauge sensor 2 , which is held with two fastening screws 3 a and 3 b. The signal measured by DMS 4 is generated by the load via the fixed diabolo connection 5 via the fork shoes 6 .

Fig. 3 zeigt den gleichen Ausschnitt wie Fig. 2 jedoch in belaste­ tem Zustand. Fig. 3 shows the same section as Fig. 2 but in the loaded state.

Die in Fig. 2 und 3 dargestellte Diabolo-Verbindung 5 hat zwei plan­ parallele, vorzugsweise Kreisflächen 7a und 7b und ist im Gabelschuh 6 mit zwei Befestigungsschrauben 8a und 8b gehalten. Auf der Gegenseite wird diese Diabolo-Verbindung 5 im Meßaufnehmer 2 mit der Befestigungs­ schraube 9 gehalten. Die Wirkung der nach allen Seiten nachgiebigen Diabolo-Verbindung 5 wird durch die Einschnürung 10 erreicht.The diabolo connection 5 shown in FIGS. 2 and 3 has two plane parallel, preferably circular surfaces 7 a and 7 b and is held in the fork shoe 6 with two fastening screws 8 a and 8 b. On the opposite side, this diabolo connection 5 is held in the sensor 2 with the fastening screw 9 . The effect of the diabolo connection 5 , which is flexible on all sides, is achieved by the constriction 10 .
