Abstract
The utility model relates to a sensor, particularly a plate type sensor. The sensor comprises a flat plate, the flat plate is axially symmetrical and does not need special fixing equipment when in use. In addition, the flat plate can directly be connected with a measured object, particularly in railroad track load measuring aspect, etc. The metering equipment can be simplified, and the utility model has the advantages of convenient installation and high measuring precision. In especial, because of the axial symmetry of the plate type sensor, when the utility model is under the action of vertical force, the plate type sensor can bear any other external force except the measured load, such as bending moment, torsional moment and horizontal force. Moreover, the measuring precision of the measured load can not be affected.
Description
The utility model relates to a kind of sensor, particularly a kind of board-like sensor.
Pressure transducer at present commonly used is mainly forms such as pillar, bridge-type, radial, box, beam type, more than various sensors when in use linking with testee, install and keep in repair the inconvenience that all has to a certain degree, especially when measuring the load of girder construction, as measure railroad track when load, use just unusual difficulty of the sensor.
The purpose of this utility model is that a kind of board-like sensor will be provided, this sensor can be directly and testee link, easy to use, the measuring accuracy height.
The purpose of this utility model is achieved in that a board-like sensor comprises a flat board, this panel axes symmetry, its upper surface middle part is provided with a weighted table, on the transversal line of above-mentioned weighted table with longitudinal axis left and right be provided with symmetrically can with the through hole of testee Joint, the bottom, left and right two ends of described flat board, be respectively equipped with the force-bearing table that links to each other with foundation structure, described force-bearing table is provided with the through hole that can fix described sensor, is provided with breach symmetrically along plate edge and transverse axis between the weighted table of described force-bearing table and dull and stereotyped upper surface.
The board-like sensor that the utility model proposes does not in use need special stationary installation, can be directly and testee link, particularly, metering outfit is simplified greatly at aspects such as measurement railroad track load, easy for installation, its measuring accuracy height, especially because the axial symmetry of board-like sensor construction makes it when being subjected to vertical force, can also bear tested load other any external force in addition, as moment of flexure, moment of torsion, horizontal force, and do not influence the measuring accuracy of tested load.
Concrete structure of the present utility model and most preferred embodiment thereof are provided by the following drawings.
Fig. 1 is the schematic top plan view according to the board-like sensor that the utility model proposes;
Fig. 2 is along the cross-sectional schematic of A-A line among Fig. 1;
Fig. 3 is that the user mode master according to the board-like sensor that the utility model proposes looks synoptic diagram;
Fig. 4 is the user mode schematic top plan view according to the board-like sensor that the utility model proposes.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, one board-like sensor 1 comprises a flat board, this panel axes symmetry, its upper surface middle part is provided with a weighted table 3, on the transversal line of above-mentioned weighted table 3 with longitudinal axis left and right be provided with symmetrically two can with the through hole 2 of testee Joint, the bottom, left and right two ends of described flat board is respectively equipped with force-bearing table 4, be respectively equipped with the microscler through hole 6 of plural fixing described sensor on the described force-bearing table 4, be provided with breach 5 symmetrically along plate edge and transverse axis between the weighted table 3 of described force-bearing table 4 and dull and stereotyped upper surface.
As shown in Figure 3, Figure 4, in use, board-like sensor 1 is arranged on the basis 12, its force-bearing table 4 contacts with the basis, by means of attachment bolt 7 with sensor 1 and basic 12 Joints, one backing plate 10 is arranged on the described weighted table 3, and described backing plate 10 is provided with rail 9, by means of the through hole on fastener 8, bolt 11 and the sensor 2 with rail 9, backing plate 10, board-like sensor 1 Joint.When Train Wheel to when the track, rail is about to power and is delivered on the board-like sensor, thereby has obtained pressure signal.Above-mentioned weighted table 3 and force-bearing table 4 can be one with the flat board of board-like sensor, also can be splits.The material of described board-like sensor, and sensor mechanism identical with known pressure transducer.
Claims (2)
