Description

Apparatus for measuring motor vehicle test bobbin charge
Technical field
The present invention relates to weighing device, especially relate to a kind of apparatus for measuring motor vehicle test bobbin charge.
Background technology
At present, general mobile testing line online weighing device is independent axle load monitor station on the market, and this monitor station mainly is made up of framework and load-bearing table top and electronic instrument.The load-bearing table top is fixed 4 pressure-strain sensors respectively for four jiaos.When sensor was under pressure, the resistance of resistance strain gage changed, thereby can export a voltage signal that is directly proportional with pressure.This axle load detection mode is not easy to combine with braking force measuring apparatus, take than large space, and each axle load measuring point needs four pressure-strain sensors, post processing circuitry complexity.
Also just like the compound detection device of patent " Motor Vehicle Brake Plate power, axle load combined type dynamic measuring instrument " (patent No. ZL96219486.7), this pick-up unit is made up of two to four wheel braking forces, wheel load compound detection plate, and several wheel load sensors are arranged again on every plate, the general structure complexity, the manufacturing cost height, data processing is also cumbersome, is not easy to apply.
Summary of the invention
In order to solve the problem that exists in the background technology, the purpose of this invention is to provide a kind of apparatus for measuring motor vehicle test bobbin charge.
The technical solution adopted for the present invention to solve the technical problems is:
Comprise base plate, beam type weighing and sensing apparatus, cylinder is spacing and protective device and weighing plate; Both sides in the middle of the base plate upper flat plate are intrinsic beam type weighing and sensing apparatus respectively, at the spacing and protective device of the both sides of two the beam type weighing and sensing apparatuses symmetrical intrinsic cylinder of difference, one end of two beam type weighing and sensing apparatuses is connected with weighing plate respectively, spacing and the protective device of described cylinder has four groups, every group is by first limited block, second limited block, cylinder, stationary installation is formed, stationary installation is fixed on cylinder on the base plate, first limited block is fixed on below the weighing plate, second limited block is fixed on the cylinder piston rod, forms spacing pair between two limited blocks; Described two beam type weighing and sensing apparatuses, each all passes through two first bolts and fixedlys connected with base plate; Described weighing plate is bolted on the beam type weighing and sensing apparatus by second, and pad is housed between the two, with the gap between the bolt head that guarantees the weighing plate and first bolt.
The beneficial effect that the present invention has is:
1) used sensor is few, and is simple in structure.
2) reduced post processing circuitry, the reliability of system is increased.
The present invention is mainly used in weighing and braking in the integral type monitor station in the drum-type motor vehicle detecting system, and purpose is to weigh for the axle that detects vehicle.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a side view of the present invention.
Fig. 3 is the vertical view under the weighing plate of the present invention.
Fig. 4 is a weighing plate ground plan of the present invention.
Among the figure: 1. base plate, 2. beam type weighing and sensing apparatus, 3-1. limited block, 3-2. limited block, 3-3. cylinder, 3-4. stationary installation, 4. bolt, 5. pad, 6. bolt, 7. weighing plate.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the present invention includes base plate 1, beam type weighing and sensing apparatus 2, cylinder is spacing and protective device and weighing plate 7; Both sides in the middle of base plate 1 upper flat plate are intrinsic beam type weighing and sensing apparatus 2 respectively, at the spacing and protective device of the both sides of two the beam type weighing and sensing apparatuses 2 symmetrical intrinsic cylinder of difference, the other end of two beam type weighing and sensing apparatuses 2 is connected with weighing plate 7 respectively, spacing and the protective device of described cylinder has four groups, every group is by the first limited block 3-1, the second limited block 3-2, cylinder 3-3, stationary installation 3-4 forms, stationary installation 3-4 is fixed on cylinder 3-3 on the base plate 1, the first limited block 3-1 is fixed on below the weighing plate 7, the second limited block 3-2 is fixed on the cylinder piston rod, forms spacing pair between two limited blocks; Described two beam type weighing and sensing apparatuses 2, each all passes through two first bolts 4 and fixedlys connected with base plate 1; Described weighing plate 7 is fixed on the beam type weighing and sensing apparatus 2 by second bolt 6, pad 5 is housed between the two, gap with between the bolt head that guarantees the weighing plate 7 and first bolt 4 does not contact between the spiral shell head of the weighing plate 7 and first bolt 4 when this gap is used to guarantee the cantilever beam sensor stress deformation.
Described beam type LOAD CELLS can be commercially available, as model: CL-YB-31.
Function of the present invention is achieved in that
Single or two coaxial wheels reach before the weighing plate 7 at motor vehicle, four cylinder 3-3 outside inflations, limited block 3-2 is inwardly moved, be resisted against on the limited block 3-1, vehicle wheels reaches weighing plate 7 then, has so just avoided beginning because the unbalance stress on the weighing plate 7 causes sensor device 2 and weighing plate 7 to suffer damage; Regulate vehicle wheels position on weighing plate 7, be located at weighing plate 7 central authorities, give the inboard inflation of cylinder 3-3 then, make limited block 3-2 outwards move to extreme position, at this moment the weight on the weighing plate 7 is all from the weight of vehicle wheels, the value of two LOAD CELLS 2 of sensor 2 value stabilization post-samplings to be weighed then is input in the computing machine through the signal processing circuit in the switch board; Before the weighing plate 7, to four cylinder 3-3 outside inflations, limited block 3-2 is inwardly moved once more under vehicle wheels is sailed, be resisted against on the limited block 3-1, treat that vehicle wheels leaves weighing plate, cylinder is lost heart, one-shot measurement is finished.
