The attached steel rail wheel weight sensor comprises a ring body (4), a web plate (5) is connected into the ring body and is provided with a resistance strain gauge (8), the radial outward extension of the outer side of the ring body is connected with four fixing ends (3) with a plurality of bolt through holes arranged uniformly along the peripheral direction, four mounting terminals (2) corresponding to the fixing ends are connected with the fixing ends through screws (6) and can also be connected with a steel rail web plate (1), part of a wire grid (81) of the resistance strain gauge is arranged parallel to the connecting line of two fixing ends in one diameter direction of the ring body, the other part of the wire grid of the resistance strain gauge is arranged parallel to two fixing ends in the other diameter direction of the ring body, and one diameter direction and the other diameter direction are arranged in a right-angle crossing way. The attached steel rail wheel weight sensor is suitable for measuring force or stress born by a component.
Description
Technical field
The present invention relates to relate to and use the device that character that resistance changes with amount of force is come metering power or stress.
Background technology
The resistance strain sensor profile is made cylinder shape, fill in the hole of reserving on the rail web, when wheel passes through rail, rail is subjected to stress makes the hole on its web produce deformation, the compressing sensor makes the foil gauge in the sensor stressed, cause the sensor output resistance to change, conversion draws the wheel load measured value according to resistance variations.This scales is squeeze-in type wheel load force transducer or filling type sensor, as the sensor of patent No. ZL200820166197.6, ZL200820166198.0.Needing punches on rail or member in advance cuts owing to the use of this sensor is installed, thus rail or the reduction of member safety in operation, and the I﹠M of sensor is cumbersome.
Summary of the invention
The present invention will solve filling type sensor I﹠M trouble, the rail of bearing load or the low problem of member safety in operation, a kind of adhesion type rail wheel load sensor of the present invention is provided for this reason, and this sensor I﹠M is convenient, the safety in operation height of rail or member.
For addressing the above problem, the technical solution used in the present invention is to be provided with ring body, be connected with web in the ring body, web is provided with resistance strain gage, its special character be ring body outer radial extension be connected with circumferentially four uniform stiff ends that have screw perforation, be provided with four corresponding with described stiff end, can be through screw mounting terminal that be connected with stiff end and that can be connected with the rail web, the wire grid part of described resistance strain gage is parallel with ring body one diameter direction two described stiff end lines, another diametric(al) two described stiff end lines of resistance strain gage wire grid remainder and ring body are parallel, a described diameter direction and another diametric(al) right angle intersection.
The present invention should be provided with the location and installation module of separating with described ring body, mounting terminal, the location and installation module has a ring bodies, the ring bodies periphery is provided with radially extension, circumferential four uniform lugs, have screw perforation on the lug, the screw perforation on lug and the lug is corresponding with stiff end and the screw perforation on the stiff end on the described ring body one by one.The location and installation module is used when the present invention installs, and purpose is convenient the installation.
The described connection with the rail web is meant welding or bonding.
Can offer four apertures as required on the web in the ring body of the present invention, be used to adjust stress distribution.
It is by the location and installation module four mounting terminal to be welded or are bonded on the rail web earlier that the present invention installs, and with screw the described ring body stiff end of sensor is installed on the mounting terminal again.Four mounting terminal are positioned near the rail web neutral line, and are in four drift angle places of a square respectively, and this square base is parallel with the rail web.When the rail web was in level, square a pair of angular direction two mounting terminal lines and horizontal line angle were 45 °, and another is 135 ° to angular direction two mounting terminal lines and horizontal line angle for square.Correspondingly, the wire grid of a resistance strain gage part is 45 ° with the horizontal line angle in the sensor of the present invention, and remainder and horizontal line angle are 135 °.When the locomotive wheel recast is used on the rail, produce detrusion near the rail web neutral line, make web produce (compression) distortion that stretches in 45 ° of (135 °) directions, because sensor is combined closely on the rail web, therefore sensor produces (compression) distortion that stretches along 45 ° of (135 °) directions simultaneously, so sticking on the resistance value of the resistance strain gage on the sensor web changes, produce the output voltage that is directly proportional with wheel load P by the Hui Sideng circuit sensor, thereby realize the metering to the locomotive wheel load: S=KP.S-sensor output parameter wherein; P-wheel load; K-constant.
The present invention is owing to be connected with circumferentially four uniform stiff ends that have screw perforation in the ring body outside, be provided with four corresponding with stiff end, can be connected with stiff end through screw and the mounting terminal that can be connected with the rail web, thereby can be connected in the rail web with four mounting terminal, with screw the stiff end on the ring body of the present invention is connected in mounting terminal again, realize installation of the present invention, so of the present invention installing and using need not to open in advance mounting hole on rail or member, the safety in operation of rail or member is improved greatly, and make I﹠M of the present invention become easy.Again owing to the wire grid part of resistance strain gage among the present invention is parallel with ring body one diameter direction two stiff end lines, another diametric(al) two stiff end lines of resistance strain gage wire grid remainder and ring body are parallel, so foil gauge wire grid length direction is subjected to stress-strain identical in stretching, the force of compression direction that 45 °, 135 ° directions produce with rail, so the present invention can accurately measure the locomotive wheel load on the rail when using, and records locomotive weight thus.
