Measuring system for static and / or dynamic loads.

专利摘要:
In a measuring system for static and / or dynamic loads of heavy objects, such as heavy equipment or machinery, a measuring device (9) is activated as a function of the load of the object. A supporting body (1), on which the object to be measured rests, is supported on a plate element with laterally protruding tabs (5a, 5b), which bend in dependence on the internal compressive stress of the supporting body (1) and their degree of bending by the measuring device (9 ) can be determined. This means that precise and reliable measurement results are always delivered without loss of stiffness.

Description: The invention relates to a measuring system for static and / or dynamic loading of heavy objects, such as heavy equipment or machines.
A measuring system of this kind is disclosed in document CH-A-707 128. It comprises a leveling shoe with a bottom plate, a wedging actuator and a height-adjustable support plate on which the article is placed, the load of the article being measured in dependence on the relative change in length between the unloaded and loaded state of the leveling shoe becomes. This known measuring system thus works on the basis of a distance measurement, from which the load of the object is subsequently determined. This measurement method has proven itself in practice limited, since the measurement results are usually somewhat jerky and therefore in many cases are insufficient.
The invention has for its object to avoid these disadvantages and to provide a measuring system of the type mentioned, which is simple in terms of design and manufacture, and always delivers precise and reliable results without loss of stiffness.
This object is achieved according to the invention that the support body is supported on a lying between him and a base plate member with a bottom of the support body largely corresponding support surface, wherein the plate member has at least one laterally projecting tab, which in dependence on the inner Compressive stress of the support body is bendable and activated according to their degree of deflection, the measuring device.
The measuring system according to the invention is based on the finding that when loading the support body with the object to be measured, the plate element is subjected to the same compressive stress as that in the interior of the support body. Between the upper and the lower surface of the tongue a load-dependent displacement of the flap is caused, which can be converted into a precise and easily measurable signal for the height of the load with a corresponding flap length. Because the measuring device does not contain any moving, stretchable or articulated components, it also ensures that it works without loss of stiffness and thus always achieves precise measurement results.
The invention further provides that the support body is formed by a press block having a preferably rectangular, polygonal, round or similarly shaped cross-section, wherein the tab protrudes laterally from a longitudinal edge of the press block. Due to the massive press block the perfect rigidity of the support body is guaranteed. Its uniform cross-section produces in the plate member also in the plate surface uniform compressive stress. The arrangement of the tab in turn contributes to their degree of deflection accurately reflects the level of internal compressive stress.
In order to produce a clearly defined measurement signal, the tab is slightly lifted in the unloaded state of the body. To optimize the signal, it is expedient to edge the plate element both in the middle region of the tab and close to the longitudinal edge of the press block.
The invention also provides that the plate element is provided with at least two preferably identically formed tabs on preferably mutually parallel longitudinal edges of the press pad. This allows the optional arrangement of the measuring device on one or the other side of the pressing block, as well as the measurement in at least two spaced points of the bottom surface of the pressing block. Of course, this also applies to the arrangement of further tabs on the other longitudinal edges of the pressing block.
Finally, the invention also provides that the measuring device is controlled by signals preferably generated by laser beams, which sends them targeted to the respective active tab and sends them back to the measuring device according to their degree of bending.
The invention will be described below with reference to an embodiment with reference to the drawings. It shows:
Fig. 1 is a schematic view of a measuring device with the corresponding arrangement.
In Fig. 1, an inventive measuring device for static and / or dynamic loads is shown schematically. The device consists essentially of a support body 1 for the object to be measured and a lying on a stable base body 2 plate member 3, on which the support body 1 is supported and the base 4 largely coincides with that of the lower base of the support body 1. In principle, however, the object to be measured could also rest directly on the plate element 3.
The support body 1 is formed as a press block and made of steel or a similar stable material. In the described embodiment, it has a prismatic shape with a right or square cross section. The geometry of the pressing block can nevertheless vary depending on the operating conditions of the measuring device.
The plate member 3 has laterally projecting tabs 5a, 5b along two mutually parallel longitudinal edges 6a, 6b of the pressing block. In the described embodiment, they extend along the

Total length of the longitudinal edges. But it is also possible to restrict them to one or more subregions of the longitudinal edges, their length and width being dependent on the particular conditions of use from case to case. It is also possible to provide the other longitudinal edges of the press block with such tabs. The tabs 5a, 5b are formed so that they are slightly offset from the base body 2 in the unloaded state relative to the support surface 4 the plate member 3. For this purpose, the plate member 3 at a location 7 is tight or flush at the longitudinal edges of the pressing block and at a second point 8 in the central region of the tabs 5a, 5b folded. There are corresponding angles α and β formed, which can vary within certain limits depending on the conditions of use. This also applies to the length and width as well as the number and geometry of the tabs on the longitudinal edges of the pressing block. The inventive measuring system operates in such a way that when loading the support body 1 with the object to be measured, the tabs 5a, 5b are bent in response to the internal compressive stress of the support body and activate according to their degree of deflection a measuring devices 9 by means of laser beams 10, the measuring device sends the laser beams to the tabs 5a and / or 5b and reflect them modified to the measuring device. In the described embodiment, a single measuring device is provided which cooperates with the one tab 5a. A similar arrangement is also possible for the tab 5b, more preferably with a measuring device on the opposite side of the pressing block. In arrangements with several tabs that are active at the same time, the load is advantageously taken by measurement data of a tab for the measurement, while the measured data of the other tabs are to serve as security values. The measuring device according to the invention can also be operated with other signal transmitters which act in a similar way to laser beams, for example with an optical, magnetic or mechanical measuring device. Advantageously, the plate member is calibrated with the tabs before use to determine the absolute values for the operational loads. In addition, monitoring of the measured values is advantageously provided in order to take into consideration possible changes in the degree of bending that arise as a result of the duration of use. Instead of such tabs other shapes, such as strips or the like could be used. For these plate elements, a metal, such as steel, spring steel, or other flexible material is suitable. claims
