Description
Technical field
The utility model relates to the device of metering power or stress, particularly uses the device that character that resistance changes with amount of force is come metering power or stress.
Background technology
Compare with disconnected rail type track weighing device, it is low that continuous rail track weighing device has cost, short construction period, characteristics such as stability in use, reliability and high safety.
The weighing device of existing continuous rail track weighing device main rail cushion sensor and two kinds of forms of filling type sensor.Rail cushion sensor also claims the pressure type sensor, it is that the form with sleeper replaces regular sleeper between two regular sleepers of the alternate distance of track section, be encased inside below the rail, its quantity is decided according to the actual requirements, as many as is several, tens, few to one, two, when wheel from the rail through out-of-date, its weight directly affacts on the sensor by rail, realizes Weighing.This device since between Weighing Area and non-Weighing Area existence one zone of transition, thereby influence the raising of weighing precision.The filling type sensor is installed near the mounting hole of reserving the rail web central core as the pressurized device, when wheel from the rail through out-of-date, rail is subjected to heavily to produce deformation, its Stress Transfer realizes Weighing to sensor.The major defect of this device is that the weighing zone is short, thereby influences weighing precision.
Rail cushion sensor and filling type sensor groups are lumped together, constitute the continuous rail track of combined type weighing device, can overcome both and use the low problem of lacking of institute's weighing precision that produces separately with the weighing district.What the previous CN2398620Y of one of inventor announced is exactly this weighing device.And because the installation of filling type sensor needs to open in advance mounting hole near rail web central core, the requirement of mounting hole is comparatively strict, thereby increased the complicacy of installing, and the perforate meeting influences the security of railway operation to a certain extent on the rail web, particularly under the situation that current locomotive constantly raises speed, more become the safety factor that needs consideration.
Summary of the invention
The utility model will solve the existing continuous rail track of combined type weighing device and install complicated, the problem that security is not high enough, provide a kind of combined type of the present utility model to be disconnected rail track weighing device, this weighing device is installed simple relatively, safe to use for this reason.
For addressing the above problem, the technical solution adopted in the utility model is to be provided with rail cushion sensor, its special character is that pad is provided with rail cushion sensor below the rail between alternate two sleepers of track section, and rail web one side between described two sleepers and the rail cushion sensor respectively is provided with the clamping touch sensor;
Described clamping touch sensor has ring body, be connected with web in the ring body, web is provided with resistance strain gage, the ring body rear end is connected with end cap, be provided with the support that is positioned at rail one side that is connected in pedestal, be provided with clamping screw in the screw of support, when described sensor ring body relied on the rail web, described clamping screw front end energy overhead was in the outer end of described sensor end cap.
The wire grid part of the resistance strain gage of described clamping touch sensor is parallel with ring body one diameter direction, resistance strain gage wire grid remainder and described diametric(al) right angle intersection, when described wire grid when a part and horizontal direction angle when being 45 °, wire grid remainder and horizontal direction angle are 135 °.
Described rail cushion sensor can be one, also can be alternate two or more.One or two s' the axle for vehicle mode of weighing that is suitable for, a plurality of bogie of car mode and whole vehicle modes of weighing of weighing that are suitable for.
Can on the web of described clamping touch sensor, have circumferentially four uniform holes, these four holes are one by one corresponding to each drift angle place of square, when two holes, a pair of angular direction of described square are positioned at horizontal direction, a described wire grid part is 45 ° with the horizontal direction angle, and wire grid remainder and horizontal direction angle are 135 °.
The ring body of described clamping touch sensor has a flexible transition district.
Clamping touch sensor in the utility model is two pairs of front and back, is each positioned between front and back two sleepers and the rail cushion sensor.Clamp touch sensor install be its ring body front end closing near rail web central core, should keep the wire grid part of resistance strain gage is 45 ° with the horizontal line angle, to answer pretty remainder wire grid and horizontal line angle be 135 ° to resistance at this moment; Clamping screw is held out against in sensor end cap, tighten described set nut, sensor is held out against in the rail web.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 the tight closing of sensor is on the rail web, therefore the sensor ring body 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; The P-wheel load; The K-constant.
Rail cushion sensor in the utility model belongs to the prior art part.This sensor places below the rail with the alternative regular sleeper pad of its body.Body is provided with the rail draw-in groove above the middle part, and extension place, draw-in groove both sides is provided with the fastener mounting hole, and the nearly both ends of body are provided with strain bore, are provided with resistance strain gage in the hole, and the body two ends are provided with to install uses stud bolt hole.
The utility model is owing to be provided with rail cushion sensor between two sleepers, respectively be provided with the clamping touch sensor on the rail web between two sleepers and the rail cushion sensor, rail cushion sensor has responsive and stable signal output in the weighing district, between non-weighing district, front and back and weighing district, have zone of transition and influence measuring accuracy, and this weak signal zone of transition is just in time replenished by the measuring-signal of front and back clamping touch sensor; Otherwise independent clamping touch sensor occurs weak signal area because effectively the weighing district is too short between the two sensors of front and back, and this weak signal area is just in time replenished by the measuring-signal of rail cushion sensor, and two kinds of sensor complementations produce good metering effect.Again because the utility model adopt to clamp touch sensor, so the not high enough problem of installation complexity, security of having avoided the filling type sensor to be produced in the perforate of rail web.
