Definitions
- the invention relates to a Schiebegate for a vehicle of public passenger transport.
- a generic sliding door is used to facilitate people getting in and out of a public transport vehicle. For this reason, they have a retractable and extendable tread plate with a load-bearing tread surface.
- the tread plate is usually arranged in a frame as a receiving device, which is firmly connected to the vehicle.
- Tritt vomsenstechnik is often realized by means of a contact pad and / or proximity switches. As the required heights are getting lower and lower in boarding systems, it becomes increasingly difficult to accommodate the detecting elements. These are due to unavoidable such. As mechanical shocks, dirt, moisture, spray or frost comparatively prone to failure and subject to high wear.
- DMS sensors bending sensors or strain gauges
- different positions are suitable for mounting the strain gauge sensors. It is essential that deformation takes place at the used components or positions under load. This deformation can be measured with the strain gauge sensor and evaluated as a signal.
- DE 10 2009 039 035 AI shows a tread frame and a linearly displaceable guided therein tread plate.
- at least one measuring element is provided, which is arranged in the region of at least one of the fastening elements of a frame.
- the measuring element may include a strain gauge, for example as a strain gauge press-fit sensor.
- the installation and maintenance of the measuring element is relatively expensive. Also, the arrangement can not be easily transferred to other sliding steps without having to make technical adjustments.
- strain gage sensors it is often difficult in known systems to protect strain gage sensors from mechanical stress.
- complete DMS systems are often used, such.
- strain transducers torque transducers or load cell, such as shear load, load cells, pressure cells, force measuring pin or train-pressure-force transducer.
- load cell such as shear load, load cells, pressure cells, force measuring pin or train-pressure-force transducer.
- the sliding step should allow a reliable measurement, the space required should be low and it should be a simple assembly and disassembly of the sliding step possible.
- the Schiebecher should also be suitable for retrofitting into existing systems, if necessary. With only a small amount of change and for different required installation heights or platform heights.
- the sliding step thus has at least one second tread plate, which is arranged above or below a first tread plate.
- the control of the tread plates can be configured such that the driver of the vehicle when crossing the border actuates a switch, which determines which tread plate extends at the stations.
- the tread plates can also be controlled such that they extend at different distances at a station, so that the treads form a kind of staircase.
- the two tread plates can be fastened together in the entry / exit device or on the vehicle, but advantageously each tread plate has at least one own fastening device.
- cranking advantageously runs in the horizontal plane, that is to say in the entry and exit plane of the tread plate. Basically, depending on the installation condition but also a vertical cranking conceivable. In the following explanations of the invention is based on a horizontal offset.
- the strain gauge is arranged obliquely to the substantially straight side cheek. Due to the inclination of the strain gauge Torsion influences that can occur due to the lever arm of the laterally arranged role largely excluded.
- the cranked section has at least two strain gauge elements which measure independently of one another and their values are evaluated independently of one another.
- the two strain gauges extend substantially in the horizontal plane and measure substantially deformations in the vertical direction, in particular from above.
- conclusions can also be drawn about forces from other directions.
- the use of at least two strain gauges makes it possible to determine forces at an angle to the vertical or even from horizontally acting forces.
- the determination of horizontally acting forces can be further improved by additionally extending at least one further strain-measuring element essentially in the vertical plane and essentially measuring deformations in the horizontal direction.
- This vertical strain gauge can replace one of the horizontal strain gauge elements, but it can also be provided in addition.
- the strain gauges are preferably protected by a cover. This can in particular be releasably secured.
- Strain gauges are particularly suitable as strain gauges. These are glued in a particularly advantageous embodiment of the bent portion, alternatively, they can also be screwed or riveted.
- the introduction of the load is often at different positions of the tread.
- the measurement results or signals are combined in a sum signal.
- the sum signal thus provides a load-dependent value, which is independent of the position of the load application on the tread plate, as well as independent of the extended position of Ausschubs.
- At least one of the two side cheeks is formed by a substantially straight side wall element and a sensor cheek element having the bent section.
- the side cheek element and the sensor cheek element are positively connected to each other and each have one of the rollers.
- the sensor cheek element can thus be subsequently attached to a free end of the side cheek.
- the free end is arranged in the direction of extension of the tread plate behind, is thus when using a housing usually in the housing of the sliding step.
- the side cheek is thus constructed in two parts, wherein both elements, the side cheek element and the sensor cheek element each carry at least one roller. According to the invention, this makes it possible to retrofit sliding steps with sensor cheek elements, a complete replacement of the sliding step or the tread plate can be dispensed with.
- the crank causes the rollers on the two elements are aligned with each other, in the insertion / Ausschubides thus arranged one behind the other and thus can roll together in a rail mounted on the vehicle.
- connection of the side cheek element and the sensor cheek element can be fixed or detachable.
- a detachable connection offers a screw on.
- At least one feather key can furthermore be arranged, via which, in particular, shearing forces can be transmitted.
- the feather key can be positioned in front of or behind the screw connection, but also below or above.
- the use of the additional feather key is also suitable if, for example, a riveted joint is used instead of a screw connection.
- the measuring zone is also in the extension direction of the tread plate behind the connection. This ensures that the connection between the elements has only a small influence on the measurement signal. A shift of the zero point is almost excluded by this arrangement.
- a sliding step according to the invention has cylindrical, straight rollers on one side and profile rollers on the opposite side. On the one hand this ensures that lateral or horizontal forces can be measured, on the other hand, this tolerance compensation with respect to the width of the tread plate or the distance of the rails is possible.
- the cylindrical rollers absorb the vertical forces that occur when entering the extension.
- the horizontal forces such as twisting due to lateral impacts, are absorbed by the profiled rollers.
- the profile rollers absorb vertical and horizontal forces caused by entering the extension and / or by lateral loading. Horizontal forces can z. B. occur by rotation of the Ausschubs by lateral shocks.
- the sensor cheek element according to the invention is designed such that it can be added on both sides of the two side cheek elements. Accordingly, for example, the holes for the screw or the key are arranged symmetrically. In a particularly advantageous embodiment, two holes are provided for screw connections, which extend in the horizontal direction through a connecting portion of the sensor cheek element. Due to the symmetrical design, a sensor cheek element can be attached to the right or left side cheek element.
- the sliding step can have centering devices for the tread plates, which each comprise a centering element fixedly arranged on the frame and fixedly arranged on the sliding trough, which interact in such a way that when the tread plate is pushed into the frame the tread plate is positioned in a predetermined position.
- the tread plates in the rear, inaccessible area no longer need to be attached.
- the fastening devices are arranged in the region of the insertion opening and the centering devices in the insertion opening opposite region, ie. in the rear region of the device are arranged. As a result, a front attachment for fixation alone 0
- a screw connection can be used in an advantageous manner.
- the frame may have guide devices, in particular slide rails
