Abstract
The utility model provides a sensor for detecting locomotive vehicle wheel load by wheel rim bearing strength and mainly applied on locomotive vehicle wheel load detection with wheel load as a detection target. The sensor mainly comprises a walk rail, a bearing rail, elastic bodies, a pedestal and a high strength bolt. The wheel rim sensor avoids the phenomenon that wheel load transfers between coaxial left and right wheels, which is caused by the season that a contact surface between a wheel set tread and a rail is not a fixed surface because of the movement of a train and a shape of a rail working surface, etc., i.e. even a gross vehicle weight is accurate, the error of the wheel load is great owing to non weighing reasons, thereby realizing high accuracy measurement of locomotive vehicle wheel load.
Description
Technical field
The present invention relates to the rolling stock weighing-appliance, more specifically saying so a kind of is the weighing-appliance that detects target with the rolling stock wheel load.
Background technology
Along with the stable development of national economy, the China railways cause has also welcome the gold opportunity phase of development.With EMUs and high-power locomotive is the novel locomotive vehicle of representative, launches in China as the emphasis of railway development.Its bogie structure with conventional train is different; Its framework does not have cartridge; The left and right sides does not have the standalone elastic spring system; Wheel be to can not adjusting load-carrying automatically, left and right wheels load-carrying balance mainly by adjustment journal box spring bearing height (specifically padding existing) or adjustment air spring height through the adjustment journal box spring up to the requirement of measurement result conformance with standard, and these adjustment are foundation with each wheel load data all.Therefore, in order to guarantee traffic safety, the novel locomotive vehicle all must detect its wheel load before dispatching from the factory with after the maintenance.
If sensor adopts tread load weighing wheel load; Owing to the surface of contact of wheel tread and rail is not a stationary plane because of reasons such as the motion of train and rail workplace shapes; Cause weight about between the phenomenon that shifts; Though promptly gross combination weight is very accurate, wheel load is owing to the non-reason of weighing causes error bigger.
Summary of the invention
In order to reduce the reproducibility error of wheel re-detection in the operation of weighing; Improve staff's adjustment bar rate, the invention provides a kind of sensor of roller edge load, lift wheel tread by guiding mechanism earlier during detection and leave rail workplace entering load rail; Be supported on by wheel rim on the load rail of sensor; Bear the gravity that vehicle distributes, can measure wheel load accurately, solved effectively owing to the non-reason of weighing causes the bigger problem of wheel load error.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of roller edge load detects the heavy sensor of rolling stock wheel, and being mainly used in the wheel load is to detect in rolling stock wheel's re-detection of target.Mainly form by rail, load rail, elastic body, pedestal and high-strength bolt.Described load rail links to each other through high-strength bolt 2 with elastic body, and elastic body links to each other with pedestal through high-strength bolt 1, and pedestal links to each other with the basis through prepared screw-bolt hole, and rail separates with the load rail and do not link to each other.During the wheel re-detection, wheel rests on the load rail wheel rim.
Described wheel load passes to elastic body by the right wheel rim of wheel, and the coaxial left-right wheel load does not produce mutual transfer when making rolling stock to be detected.
The top of the top shape of described rail and GB rail is on all four, and its length is 900mm, and rail does not contact with wheel, just the link of sensor.
Described tested wheel does not contact with rail, and contacts with the load rail, this be since the discrepancy in elevation on load rail bearing power upper surface and the rail less than flange height, rail is a link at this moment, and plays the security protection effect.
Described load rail is the parts that bear the wheel heavy load, long 900mm, and upper surface has horizontal plane, and is provided with safe shoulder block.It is installed on the elastic body.
Described load rail is the parts that bear the wheel heavy load; Upper surface is the surface level that certain width is arranged, and wheel load can be freely vertical on this plane, laterally mobile, behind mobile the stopping; The contact site on plane is a clear and definite point on wheel load and the load rail, makes load clear and definite.The load rail is the force transferring part of sensor.
Described elastic body is parts of measuring mechanical signal, forms unified dynamometric system by 3 elastic bodys on every sensor.
Described elastic body is the dynamometry parts of sensor, adopts the double shear force measuring method, and totally 3 elastic bodys make sensor dynamometry ride comfort good, guarantees all can detect accurate data when wheel is loaded in load rail upper surface diverse location.
The bottom of the sensor that described pedestal is made up of quenched and tempered steel, its rigidity is very big, makes sensor elastomer have stability fundamental.
Among the present invention, to passing to track, the heavy P of its axle, revolver weigh R to the rolling stock load by wheel
A left side, right wheel load R
RightRelation be:
P=R
A left side+ R
Right
If A is the spacing between the heavy heart of axle and revolver wheel rim and the load rail contact point, B is the spacing between the heavy heart of axle and right wheel rim and the load rail contact point, has so
R
A left side=PA/ (A+B), R
Right=PB/ (A+B)
Wheel rim and sensor upper surface hard point are clear and definite, can not change A and B, i.e. wheel rim difference on sensor, and A and B remain unchanged, R
A left sideAnd R
RightAlso constant, thus wheel load accurately obtained, see Fig. 2.
The invention has the beneficial effects as follows:
(1) simple in structure, convenient for installation and maintenance.
(2) realized the re-detection of high precision wheel.
Description of drawings
Below in conjunction with accompanying drawing and instance the utility model is further specified.
Fig. 1 is the structural map of instance.
Fig. 2 is the detection synoptic diagram of instance.
Rim sensor is by 1. load rails, 2. rail, 3. elastic body, 4. pedestal, 5. high-strength bolt 1 and 6. high-strength bolts 2 are formed.
Embodiment
Select number of sensors according to demand; And select the rim sensor arrangement according to the spacing of pre-detection vehicle and wheelbase; The rail that breaks arranges, and with reference to figure 1, and rim sensor is linked to each other through preset high-strength bolt on the bolt hole reserved on the pedestal and the basis.
Load rail upper level guarantees highly unanimity between sensor load rail upper surface each point height and each sensor, can be through adjusting under pedestal with stainless steel gasket.
When preparation was weighed, rolling stock ran on the sensor load rail with the speed that is no more than 5km/h, treat all wheels all on the load rail and stop stable after, confirm to measure, get final product each wheel load data.
