Abstract
The application discloses a fission-type dynamic auto weighing apparatus, which is characterized in that the dynamic auto weighing apparatus comprises two small weighing platforms; the distance between the two weighing platforms is proper to the distance of auto wheels; each of the two small weighing platforms consists of a bearing plate, a bearing bracket, a frame and a weighting sensor; the length of each weighing platform is proper to the width of tyres when the auto is passing by; a gap between the surrounding of the small weighing platform frame and the bearing plate is inserted with the rubber plate of vibration absorbing; three sensors are placed below the bearing bracket of the small weighing platform, two of which are placed two adjacent angles of the frame and one is placed in the middle of another two angles of the frame; the bearing plate supports the sensor through a supporting bolt. The application has the advantages of low vibration strength, little vibration disturbance, high precision of weighting, few steep products consumed, reducing the working load of excavation and arrangement, and convenient maintenance.
Description
Technical field
The application belongs to the weight weighing apparatus.
Background technology
Existing dynamic automobile scale all is a bigger rectangle weighing platform (length satisfies automobile wheel track for generally long 3m, wide 0.8m), joins 4 LOAD CELLS below the weighing platform, is called the monoblock type dynamic automobile scale.When automobile crossed weighing platform, data acquisition unit write down weighing of each, and addition obtains the gross weight of automobile then.Its major defect is: the monoblock type weighing platform is longer, and when loaded vehicle crossed, weighing platform deflection sex change was bigger, caused violent vibration, and serious the interference weighed; Because weighing platform is big, adds damping and absorb the vibration difficulty again, in a word, vibration causes the dispersiveness of repeatedly weighing very big, so weighting error is big.In addition, during installation, need on the whole piece of charge station is had a lot of social connections, to dig zanjon one, therefore, be necessary further exploitation for dynamic automobile scale.
Summary of the invention
The application provides a kind of split type dynamic automobile scale at the problem that existing monoblock type dynamic automobile scale occurs in actual applications.
For addressing the above problem, the application's split type dynamic automobile scale comprises two little weighing platforms, the inboard spacing of two little weighing platforms is less than the wheelspan of minimum vehicle, and outside spacing is greater than the wheelspan of maximum vehicle, promptly satisfy various vehicles by the time both sides tires roll on two little weighing platforms; Each little weighing platform is formed by bearing plate, bearing frame, frame, LOAD CELLS; Be plugged with the rubber slab of absorbing in the gap between little weighing platform frame and the bearing plate; The bearing frame underneath of little weighing platform is equipped with three sensors, and wherein two sensors are placed on two adjacent angles of frame, and one is placed on the frame centre position at two angles in addition, and bearing frame is supported on the sensor by support pin.
In addition, bearing plate up-down vibration when preventing that vehicle from crossing not on two angles in addition of sensor installation, is equipped with support column at each little weighing platform.
During installation, two little weighing platforms are installed in both sides, highway toll track, the signal wire of all the sensors all is connected on the data acquisition unit.
Its principle of work is: when vehicle crossed, a weighing platform claimed the load-carrying that take turns on the right side, and another weighing platform claims the load-carrying on the revolver, and both sums are that axle is heavy, and an axle heavy phase adds as vehicle-mounted weight.
The application's advantage is:
(1) adopt two little weighing platforms to replace existing big weighing platform, two little weighing platforms are respectively born the weight of half, and the length of little weighing platform has shortened nearly 3 times than original big weighing platform, makes deflection deformation---promptly the amplitude of vibration will reduce nearly 6 times, reduce the intensity of vibration significantly.In addition, little weighing platform width has also reduced half than big weighing platform, when the speed of a motor vehicle is identical, weighing platform has also been lacked in the gap between a weighing platform frame and the bearing plate by the time of automobile effect and is plugged with the shock-absorbing rubber slab, can not only protecting against shock, can also absorb the vibration that causes when automobile crosses, stronger damping action is arranged, reduce oscillation intensity.Particularly prevent to form resonance, weaken vibration interference greatly, accuracy of weighting significantly improves.
(3) used steel are few, and excavation installation work amount reduces, and keeps in repair also more convenient.
(4) little weighing platform adopts three sensor support to constitute the stable plane of weighing, and avoids not in one plane unstable defective of four sensors, makes weighing very accurate.
Description of drawings
Fig. 1 is the application's a structural representation;
Fig. 2 is the front view of a little weighing platform in the embodiment of the present application;
Fig. 3 is the vertical view of Fig. 2.
Among the figure: 1-little weighing platform, 2-data acquisition unit, 3-rubber slab, 4-bearing plate, 5-frame, 6-support pin, 7-LOAD CELLS, 8-bearing frame, 9-support column.
Embodiment
Further specify the application's embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, two little weighing platforms 1 of rectangle that long * wide * height is 1200 * 300 * 210mm are installed in both sides, highway toll track, the minor face of little weighing platform 1 is parallel with direction of traffic, the inboard spacing of two little weighing platforms 1 is less than the wheelspan of minimum vehicle, outside spacing is greater than the wheelspan of maximum vehicle, and the sensor signal lines of two little weighing platforms 1 all is connected on the data acquisition unit 2.
As Fig. 2, shown in Figure 3, little weighing platform 1 comprises frame 5, LOAD CELLS 7, bearing frame 8 and bearing plate 4, the upper edge of bearing plate 4 and frame 5 is on same surface level, be plugged with rubber slab 3 around the weighing platform frame 5 and in the gap (being generally 3-4cm) between the bearing plate 4, and knock in jam-pack with the tinplate of 1mm and vibrate so that tightly absorb, be equipped with three LOAD CELLS 7 in each little weighing platform 1 underneath, the floor plan mode of three LOAD CELLS 7 is: wherein two are placed on two angles, little weighing platform 1 frame, 5 long limits, another is placed on the centre on frame 5 another long limits, bearing frame 8 is supported on the sensor 7 by support pin 6, and the signal wire with all the sensors 7 during installation all is connected on the data acquisition unit 2.
In addition, bearing plate 4 up-down vibration when preventing that vehicle from rolling away from two angles on the long limit of opposite side, are equipped with support column 6, leave the buffer gap between the end face of support column 6 and the bearing frame 8.
The floor plan mode of three sensors is not limited only to aforesaid way, and two sensors are placed on two adjacent angles of frame as long as satisfy wherein, and one is placed on frame and gets final product in the centre position at two angles in addition.
