Abstract
The utility model discloses a coupler with a dynamometric sensor and not only can be connected with an engine and a car, but also the coupler stress situation can be tested. The utility model is characterized in that the dynamometric sensor is installed in the coupler body of the improved coupler. One end of the coupler body is connected with the sensor, and the other end is connected with a coupler yoke frame. A socket is arranged on the coupler. The bridge power supply of the sensor is led into the socket, and an outgoing signal is led out. The utility model has the advantages of simple structure, high test precision, big safety factor, wide application, etc., and can be used for testing the resistance force of the engine and the car, and the traction force of the coupler. The coupler force of the engine can be scouted, which is favorable to the study of the best control type of the train traction.
Description
The utility model is to connect locomotive, vehicle, can test the hitch of the band force transducer of hitch force-bearing situation simultaneously again.
Existing railway locomotive, the general anastomosis that only rises of vehicle hook can not dynamometry.But the locomotive tractive effort is a key technical indexes of the evaluation performance of locomotive, must at first calculate and draw the expection tractive property curve of locomotive when the design locomotive; When utilization, also be necessary for utilization department the actual locomotive traction performance curve of accurately measuring is provided, so that utilization department selects type for use and rationally works out the circuit tonnage rating and the operation plan according to conditions such as task (visitor, goods, accent) freight volume, the vertical section of circuit faces.Present national prerssure on transport is all taped the latent power on heavy haul transport for relaxing situation.Therefore, accurately measure locomotive tractive effort value and Changing Pattern thereof; Guarantee that locomotive is efficient, safe operation just seems more important.When testing locomotive, when the vehicle hitch is stressed, adopting two kinds of methods usually: 1. adhering resistance strain sheets is formed test electric bridge on coupler hook body, and use the calibration back on special instrument and equipment.2. be at hitch the back, force transducer element of series connection carries out dynamometry in the front of energy disperser.As 1987 the 4th phases of external railway vehicle periodical " the draw bar pull problem of indian railway two-shipper car traction passenger train ", railway vehicle periodical the 4th phase of nineteen eighty-two " the vertical power detecting device of rolling stock ", all can be used as example.The 1st kind of method be because hitch is complicated steel casting, and how not carry out machine up, and the position of power transmission point sometimes might not be in coupler body central authorities.During practice, the paster of strain-gauge, the PROCESS FOR TREATMENT behind the paster, all cumbersome and difficult for work such as the group bridge mode of eliminating the moment of flexure influence, static calibrations, the dynamometry precision is not high.The 2nd kind of method outsourcing standard force-measuring sensor has very high precision, but often coupler force will just can be delivered to force transducer through numerous parts, and sensor can not directly reflect the hitch stressing conditions, has the unstable and inaccuracy factor of dynamometry.And many, the complex structure of package unit parts, draw beam or floor underframe for vehicle also will make corresponding changes, and make that the test equipment cost is higher, assembling and setting is complicated.
The utility model purpose is to provide a kind of improved hitch, and this hitch not only will guarantee normal connection, and requires dynamometry accurate, simple in structure.
The utility model is: in the coupler body of arbitrary locomotive, vehicle connection hitch a force transducer (normally pull pressure sensor) is installed, some parts by coupler head guarantee that hitch normally connects, a combination hub is installed on coupler body, link to each other their common hitches that constitutes the band force transducer with hook tail frame with a pin at the hook tail.When the suffered vertical pressure of hitch was in the rated load scope, vertically pressure was passed to force transducer by the connector of coupler head, passes to hook tail frame by another connector again, until passing to draw beam or chassis of vehicle.Here said connector can be a pin, can be thread connector also, is selected voluntarily by the user.This moment the force transducer stress deformation, the strain-gauge that attaches on the force transducer elastic body is also corresponding experiences strain, the electric bridge lack of equilibrium of being made up of strain-gauge and export electric signal.The combination hub of these signals through being contained on the coupler body picks out, and by interior equipment monitoring and demonstration.When locomotive or vehicle during at curve or running on ramp, when perhaps being subjected to vibrating, the suffered moment of flexure major part of hitch is passed to the afterbody connector by coupler body, passes to draw beam or floor underframe for vehicle by hook tail frame again.Thereby make force transducer only be subjected to purer longitudinal force effect, reduced the caused test error of moment of flexure.When this device is subjected to surpassing the impact of force transducer rated load, because the elastic deformation of parts such as force transducer is subjected to the restriction of coupler body, make force transducer and coupler body bear overload force jointly, therefore protected force transducer to exempt from destruction.Coupler body of the present utility model is the bending resistance protecting sleeve of force transducer, is again its overload protection device.
The size of hitch described in the utility model outside and connected component size is configured to the cooresponding size of hitch of known commercial use, and therefore feasible hitch according to the utility model manufacturing can be installed in replaces original hitch in existing locomotive, the vehicle.When rated load is big especially,,, just can use the utility model hitch like that by common hitch easily as hook tail frame etc. also as long as change the design size of coupler body and a few connected component.And the stickup of elastomeric material and each Cross section Design, resistance strain gage and PROCESS FOR TREATMENT and group bridge mode in the force transducer all can resistance strain gage test technology routinely be carried out.
The utility model hitch, the functions such as connection that common hitch had have not only been kept, increased the dynamometry function, and simple in structure, easy to assembly, force transducer can disassemble independent calibration, measuring accuracy height, safe and reliable applied widely easily.Can do locomotive, vehicle drag, draw bar pull test, the train locomotive coupler force monitors to be used.Help the control and the research of the best maneuverability pattern of train traction.Because of the using method and the oad of the utility model hitch and common hitch are suitable, so it can replace employed hitch in locomotive and vehicle at present.
Now in conjunction with the accompanying drawings the utility model is described in further detail.
