Abstract
The utility model relates to a portable electronic weighing instrument for wheels and axles of railway vehicles. The utility model belongs to a device for testing the load of the axles of the railway vehicles and comprises exclusive use clamps. The clamps are closely embraced on both sides of the wheels. A load sensor arranged on a rail is supported on one side of every exclusive use clamp by adjusting a supporting base. The other load sensor arranged on the rail is supported on the other side of the exclusive use clamp by a manual operation hydraulic pressure station. A clearance gauge is arranged the bottom of every exclusive use clamp and the rail. The utility model adopts the load sensors matched with a quadric digital display instrument for directly measuring the load of the wheels vertically. Therefore, the utility model overcomes the natural defect of the indirect measurement of a hydraulic system in the prior art. The load measuring precision can achieve more than 2 percents. The utility model safely satisfies the technical requirements of existing rail technical conditions for measuring the load of the axles of the railway vehicles. In addition, the utility model has the advantages of simple structure, convenient operation and convenient operation.
Description
The utility model relates to a kind of portable rail truck wheel shaft electronics weight sensing instrument, belongs to the trial assembly of resurveying of rail truck wheel shaft and puts.
Present portable weighing scale from external introduction and domestic imitation, its principle is a hydraulic test system, eject the picking-up wheel upwards with two hydraulic piston gauge heads that act on the wheel both sides with certain angle, hydraulic system pressure is converted into wheel weight under the piston gauge head by measuring.Therefore, limit by its principle is a kind of indirect measurement system, because the hydraulic system error is bigger, so cause measuring error bigger, in addition, be subjected to its structure influence, survey the device distortion in the measuring process and cause variable angle, piston friction power increasing etc. has increased measuring error more, and the uncontrollable calculating of error, so prior art exists on the principle, on the structure, the wretched insufficiency on the method, miss by a mile, can only measure for reference at most as a comparison.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and provide the loading of the direct vertical survey wheel of the supporting secondary digital displaying meter of a kind of employing load sensor, make it accuracy and be higher than 2% 1 to two order of magnitude, thereby satisfy the portable rail truck wheel shaft electronics weight sensing instrument of existing railway technology conditional request.
The purpose of this utility model is achieved in that it is made of two load sensors, secondary digital displaying meter, hand-hydraulic station, adjustable seats, unit clamp, clearance gauge.Described unit clamp is filled the span of a man's arms in the wheel both sides, place the load sensor 1 on the rail to support dried unit clamp one side by adjustable seats, place another load sensor 2 on the rail to be supported on the opposite side of unit clamp by the hand-hydraulic station, between unit clamp bottom and the rail clearance gauge is set.
The utility model compared with prior art, owing to adopt the loading of the direct vertical survey wheel of the supporting secondary digital displaying meter of load sensor, thereby overcome the inadequate natural endowment that the prior art hydraulic system is measured indirectly, the check weighing degree of accuracy reaches more than 2%, satisfied the technical requirement of existing railway technology condition to rail truck wheel shaft check weighing fully, the utility model also has advantages such as simple in structure, easy to operate simultaneously.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a fixed unit clamp structural representation of the present utility model.
Fig. 3 is an adjustable unit clamp structural representation of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is made of load sensor 1 (1), adjustable seats (2), clearance gauge (3), secondary digital displaying meter (4), hand-hydraulic station (6), load sensor 2 (7), unit clamp (8).Unit clamp (8) is filled the span of a man's arms in wheel (9) both sides, loading sensing 1 (1) places wheel (9) left side, with adjustable seats (2) pretension, load sensor 2 (7) is placed wheel (9) right side, the hand-hydraulic station (6) that places on the rail (5) is arranged down, operator brake hydraulic station (6) rises with wheel (9) jack-up piston, and when wheel track breaks away from fully, wheel (9) is all by two load sensor vertical support.At wheel track behind the certain interval, special-purpose clearance gauge (3) is placed this gap location, falling wheel (9) makes wheel (9) be pressed on the rail (5) by clearance gauge (3), earlier clearance gauge (3) is executed one along the outside pulling force of wheel (9) axis direction, while jack-up wheel (9), when wheel track and clearance gauge (3) certain when just breaking away from a flash (this moment can be provided with or side fixed) read secondary digital displaying meter (4) displayed value, promptly finish check weighing purpose of the present utility model.Unit clamp of the present utility model (8) as Fig. 2, shown in Figure 3 two kinds of versions are arranged.The same footpath of taking turns at specific wheel can be designed to bottom regular length articulated structure, and promptly the unit clamp of this version (8) is made of the lonely top board (10) in garden, steady brace (11), and the lonely top board in this steady brace (11) two ends and garden (10) is hinged.These anchor clamps are can not mode hinged, but have along the inside projection of wheel rim in the bottom, thus the existing pull bar effect of end portion again pocket hang effect.Another kind of version is at being suitable for the multiple footpath (as passenger vehicle, lorry, narrow gage vehicle etc.) of taking turns, can be designed to the adjustable articulated structure of lower length, promptly should be made of two lonely shape top boards (12) (14) and adjustable diameter and screw adjusting pull bar (13) by special use furniture (8), these adjustable diameter and screw adjusting pull bar (13) two ends and lonely shape top board (12) (14) end are hinged.These anchor clamps are hinged with the adjustable diameter and screw adjusting pull bar (13) that revolves about a pair of, take turns the length that adjustable diameter and screw adjusting pull bar (13) are adjusted in the footpath at difference, to adapt to the requirements in different wheels footpath.Hand-hydraulic station (6) in the utility model both can have been placed on the track, can select for use the hand-hydraulic station to place on the other roadbed in vehicle wheel road according to the structure specific (special) requirements again.
