Abstract
A pressure-derivation type vehicle body weighing apparatus to measure a vehicle load is characterized in that an expansion and contraction device is equipped at a leaf spring, a crossbeam or a vehicle axle, while a pressure-derivation device is equipped at the expansion and contraction device; the pressure-derivation device communicates with a pressure conversion device via a conduit; a pressure sensor is connected with both a singlechip and a signal display.
Description
Technical field
The utility model relates to a kind of weighing apparatus, and particularly a kind of pressure that is used for measuring self load carrying ability is derived formula vehicle body weighing apparatus.
Background technology
In mid-June, 2006, national correlation department is formally implemented the weight metering charging scheme, and increasing province comes into effect weight metering charging system.Existing lorry is not because have effective check weighing instrument, driver not to know how many actual weights of each shipments that the sender sends off is, by touch is estimated often, charges carriage by weight then.Above by touch comes estimation approach often to bring more or less loss to the driver, has directly reduced driver's income; Some relevant patent works are also arranged in addition, but complex structure, manufacturing cost is too high, is unfavorable for its effective popularization.
Summary of the invention
The purpose of this utility model provides a kind of pressure that is used for measuring self load carrying ability and derives formula vehicle body weighing apparatus.
The utility model is achieved in that the pressure let-off gear(stand) is placed on the retractor device, retractor device places on leaf spring, crossbeam or the vehicle bridge, under the support of retractor device at its power, the retractor device jacking, until the body portion that holds up fully more than it, the weight of vehicle body and the goods uploaded thereof is all by the retractor device carrying, the weight squeeze pressure let-off gear(stand) of vehicle body and the goods uploaded thereof, thereby be converted into hydraulic pressure, pass to pressure sensor by the oil circuit pipe.Pressure sensor is imported micro controller system and signal crossover display terminal processing back demonstration after receiving pressure signal, promptly draws the load carrying ability of automobile.
Retractor device comprises jack, hydraulic actuating cylinder, electromagnetic current fluid damper, fork hydraulic lifter etc., is prior art.Its effect is the assisting pressure sensor, holds up the above vehicle body of pressure sensor.
Its beneficial effect is: 1, avoid sensor and weighting platform direct contact, avoided the unnecessary consumption of sensor, prolonged sensor service life; 2, simple in structure, low cost of manufacture is easy to promote; 3, safeguard vehicle safety, prevent overload of vehicle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the retractor device scheme of installation;
Fig. 3 is the structural representation of pressure conversion device embodiment 1;
Fig. 4 is the structural representation of pressure conversion device embodiment 2.
1 is the piston of pressure let-off gear(stand) in the drawings, and 2 is the cylinder sleeve of pressure let-off gear(stand), and 3 is conduit, 4 is pressure conversion device, and 5 is retractor device, and 6 is railway carriage, 7 is crossbeam, and 8 is the leaf spring backing plate, and 9 is leaf spring, 10 is vehicle bridge, and 11 are pressure conversion oil cylinder, 12 pistons for pressure conversion oil cylinder, 13 is pressure sensor, and 14 are rotating shaft, and 15 is lever, 16 are the power transmission arm, and 17 is base, and 18 is balance pivot.
In Fig. 1, the piston 1 of pressure let-off gear(stand) places in the cylinder sleeve 2 of pressure let-off gear(stand), the decomposition pressure let-off gear(stand); The pressure let-off gear(stand) places on the retractor device 5, and conduit 3 is connected the pressure let-off gear(stand) with pressure conversion device.
In Fig. 2, retractor device 5 places the side of crossbeam 7, is clipped between leaf spring backing plate 8 and the railway carriage 6, and is fixed on the leaf spring backing plate 8, also can be fixed on the railway carriage 6.
In Fig. 3, oil circuit pipe 3 is communicated with pressure conversion oil cylinder 11, and the piston 12 of pressure conversion oil cylinder 11 is connected with pressure sensor 13.
In Fig. 4, oil circuit pipe 3 is communicated with pressure conversion oil cylinder 11, the piston 12 of pressure conversion oil cylinder 11 is connected with lever 15 by rotating shaft 14, balance pivot 18 is fixed on the base 17, and be connected with lever by rotating shaft, one end of lever 15 is provided with power transmission arm 16, and pressure sensor 13 is fixed on the base 17, below the power transmission arm 16.
Pressure sensor all is connected with micro controller system and signal indicator thereof.
In the process of the installation of reality and use, retractor device and corresponding pressure let-off gear(stand) and pressure conversion device are difficult to play the weighing effect, in the utility model, retractor device, pressure let-off gear(stand) and pressure conversion device can be by 2 to 8 retractor device groups of forming and pressure let-off gear(stand) group and pressure conversion device groups.
