Description
$1Q171g -Measuring Pin For Switching Forces The invention relates to a device for measuring the switching force at rail switches, comprising a sensor and a measuring pin connected with the sensor and designed as a deformation body to be inserted in a joint provided in the switch drive, the sensor being designed as an electro-mechanical sensor and arranged outside the point of application of force on the measuring pin in a head 1o connected with the measuring pin.
A device of the initially defined kind has become known from Austrian Patent No. 399,484. The known switching force meter is comprised of a slotted steel body, constituting a deformation body, carrying a sensor. The known switching force meter serves to measure the forces occurring between the switch drive and the switch, regardless of whether these forces act from the switch drive on the switch blades or as residual forces in spring switch blades or as an opening force against the retaining force or against the opening 2o resistance of the switch drive. To this end, the measuring pin is inserted in a cardan joint or in a biaxial joint instead of a switch connector pin, whereby bending beams are formed by the slots in the steel body. In the known device, bead-like enlargements are provided on the external surface, each serving as a point of application for the forces applied. The configuration disclosed in Austrian Patent No.
399,484 consists of an electromechanical sensor arranged outside the point of application of the force on the measuring pin in a head connected to the measuring pin. The 3o measuring sensor components are not subject to oscillations within the measuring pin because the electromechanical V
~181~ 1 g sensors are arranged outside the point of application of force in the head of the measuring pin. This configuration enables the use of a relatively wide head and facilitates the insertion and removal of the pin into and from the respective measuring position. A mechanically protected measuring sensor, e.g. as disclosed in U.S. Patent No.
4,530,245, could easily be incorporated in the head of such a measuring pin. In order to ensure good deformability and hence a high-quality signal, even with a thick-walled pin 1o head and with a stainless steel measuring pin and head, the head for receiving the measuring sensor of the prior art device is slotted transverse to the axis of the pin.
In a particularly advantageous manner, even with a sturdy construction, the measuring head of the prior art device includes two slots offset from each other in the axial direction ensuring that any measurement is insensitive to impacts.
Such an impact-safe and simple construction of the measuring pin may be connected to a complex evaluation 2o device by direct connection to a PC or laptop even during rough railway operation. In this configuration the sensor is connected via a signal amplifier and an analog/digital converter with a standard interface, in particular a serial interface with a computer, with a memory and a display.
The invention aims at further improving the known construction with a view to achieving sensitive measurements with a high reproducibility even at slight actuation forces, and high measuring pin stability.
Accordingly, the present invention relates to a 3o switching force measuring device for use in a rail switch of the type including a switch drive having a joint with a X181, ~9 joint axis and connector rods pivotable relative to each other about the joint axis. The switching force measuring device comprises a measuring pin with a deformable outer body for insertion into the joint of the switch drive, and an electromechanical sensor means mounted on one end of the measuring pin outside the joint responsive to deformation of the outer body resulting from the application of a force by the connector rods on the body. The measuring pin body includes three circumferentially extending annular raised 1o portions provided at different axial distances from one another outside the central plane of the joint, through which the joint axis passes, for engagement with the relatively pivotable connector rods.
Due to the fact that the annular raised portions or ribs in the manner proposed by the invention are designed to be spaced apart in the axial direction, it is feasible to introduce the actuation forces into the measuring pin sufficiently eccentrical so as to ensure an intensification of the mechanical deformation according to the lever 2o principle, and hence of the measuring signal. On the whole, a precise measured value is obtained at extremely small actuation forces due to the eccentric absorption of force, thus considerably enhancing the sensitivity of the known device without affecting the operational safety and the stability of the measuring pin.
The construction according to the invention is further developed in a manner that one of the axial distances of the annular raised portions relative to one another is greater than the width of the coupling rod forming part of the 3o joint, measured in the direction of the pivot axis of the joint, thereby ensuring that the greatest conceivable ?181719 distance for an eccentric force introduction can be utilized thus obtaining a mechanical amplification of the measured signal.
The desired extent of the eccentric force introduction for the purpose of mechanical force intensification is safeguarded by arranging the annular raised portions neighboring the sensor and head at an axial distance relative to each other that is smaller than the axial distance between the middle annular raised portion and the 1o third annular raised portion. Thereby, it is ensured that the introduction of force to the first raised portion results in the reliable deformation of the measuring pin at the clamping point of the sensor. Moreover, the configuration may be such that the measuring pin comprises an axial bore for a cable bushing. In particular such an axial bore for a cable bushing allows the cable bushing to extend downwardly from the pin in a protected manner, and a simple connector plug to be attached to the end of the measuring pin for continuing cable connections. The cable 2o connections and connector plugs, which are substantially less resistant from a mechanical point of view, can be arranged on the bottom end in a protected manner. Moreover, the encapsulation of the measuring sensor on the upper end is also feasible thus increasing the operational safety thereof. This configuration also provides a means for securing the measuring pin against rotation comprising a cover sealingly encompassing the sensor externally.
In the following, the invention will be explained in more detail by way of a comparison of the known 3o configuration with the further development according to the invention illustrated in the accompanying drawing, wherein:

In the following, the invention will be explained in more detail by way of a comparison of the known 3o configuration with the further development according to the invention illustrated in the accompanying drawing, wherein:
Fig. 1 is a diagrammatic partial view through a joint with a measuring pin inserted, according to the prior arty Fig. 2 is a perspective side view of the known measuring pin; and Fig. 3 is a partial section through the construction according to the invention.
With reference to Fig. 1, the end of a connector rod 1 includes a fork piece 2, in which the bearing eye 3 of a coupling rod 4 is inserted. The connection between the 1o bearing eye 3 and the fork piece 2 is effected by means of a measuring pin 5 comprising rib-shaped raised portions 6 on its outer surface, each engaging in the respective recess of the fork piece 2 or of the bearing eye 3, in a positive and force-transmitting manner. A head 7, in which an electromechanical sensor 8 is mounted, is attached to the free end of the pin 5. The head 7 includes a stop shoulder for receiving a plate-shaped web 9 of an intermediate piece 10. The intermediate piece 10 is mounted on the fork 2 using a portion of the piece 10 which extends transversely 2o to the plate-shaped web 9 to thereby prevent relative rotation between the head 7 and the fork 2.
Fig. 2 depicts the measuring pin 5 in detail. Annular raised portions 6 are provided on the external surface of the measuring pin body for introducing forces to the body from the connector rods. The widened head 7, provided with slots 11, contains the electromechanical measuring sensor 8 in its cavity. The electric feed line, which is appropriately secured against tension, is indicated by 12.
From Fig. 3 the construction according to the invention 3o is apparent. The respective annular raised portions or ribs 6 are arranged at a distance a and b from each other and the three annular raised portions 6 are each arranged outside the longitudinal central plane 13 of the joint, through which the pivot axis 14 of the joint passes. The measuring sensor 8 is arranged in the head 7 proximate the first annular raised portion 6. The distance c, from the first annular raised portion 6 neighboring the sensor 8 to the central plane 13 is greater than the distance b between the first annular raised portions 6 and the middle annular raised portion 6. The middle annular raised portion 6 of 1o the measuring pin 5 is located in the opening of the coupling rod 4 and absorbs forces eccentrically, whereas in the prior art devices the force absorption takes place in the longitudinal central plane 13. This shift of the middle annular raised portion 6 in the direction towards the sensor 8 out of the longitudinal central plane 13 results in the mechanical intensification of deformation and hence in the amplification of the electric measured value obtained.
In the embodiment according to Fig. 3, the cable 12 is fed through an axial bore in the measuring pin 5, and ends 2o in a connector plug 15, which extends out from the lower end of the measuring pin 5.
In order to enhance the protection, and encapsulation from environmental influences, a cover 16 is provided, which is fixed to the fork piece 2 by means of screws 17. This cover 16 sealingly encompasses the head 7 and hence the measuring sensor 8, while securing the head 7 against rotation at the same time. A slot extending in the longitudinal direction of the measuring pin 5 is indicated by 18.
With reference to Fig. 1, the end of a connector rod 1 includes a fork piece 2, in which the bearing eye 3 of a coupling rod 4 is inserted. The connection between the 1o bearing eye 3 and the fork piece 2 is effected by means of a measuring pin 5 comprising rib-shaped raised portions 6 on its outer surface, each engaging in the respective recess of the fork piece 2 or of the bearing eye 3, in a positive and force-transmitting manner. A head 7, in which an electromechanical sensor 8 is mounted, is attached to the free end of the pin 5. The head 7 includes a stop shoulder for receiving a plate-shaped web 9 of an intermediate piece 10. The intermediate piece 10 is mounted on the fork 2 using a portion of the piece 10 which extends transversely 2o to the plate-shaped web 9 to thereby prevent relative rotation between the head 7 and the fork 2.
Fig. 2 depicts the measuring pin 5 in detail. Annular raised portions 6 are provided on the external surface of the measuring pin body for introducing forces to the body from the connector rods. The widened head 7, provided with slots 11, contains the electromechanical measuring sensor 8 in its cavity. The electric feed line, which is appropriately secured against tension, is indicated by 12.
From Fig. 3 the construction according to the invention 3o is apparent. The respective annular raised portions or ribs 6 are arranged at a distance a and b from each other and the three annular raised portions 6 are each arranged outside the longitudinal central plane 13 of the joint, through which the pivot axis 14 of the joint passes. The measuring sensor 8 is arranged in the head 7 proximate the first annular raised portion 6. The distance c, from the first annular raised portion 6 neighboring the sensor 8 to the central plane 13 is greater than the distance b between the first annular raised portions 6 and the middle annular raised portion 6. The middle annular raised portion 6 of 1o the measuring pin 5 is located in the opening of the coupling rod 4 and absorbs forces eccentrically, whereas in the prior art devices the force absorption takes place in the longitudinal central plane 13. This shift of the middle annular raised portion 6 in the direction towards the sensor 8 out of the longitudinal central plane 13 results in the mechanical intensification of deformation and hence in the amplification of the electric measured value obtained.
In the embodiment according to Fig. 3, the cable 12 is fed through an axial bore in the measuring pin 5, and ends 2o in a connector plug 15, which extends out from the lower end of the measuring pin 5.
In order to enhance the protection, and encapsulation from environmental influences, a cover 16 is provided, which is fixed to the fork piece 2 by means of screws 17. This cover 16 sealingly encompasses the head 7 and hence the measuring sensor 8, while securing the head 7 against rotation at the same time. A slot extending in the longitudinal direction of the measuring pin 5 is indicated by 18.
