Abstract
A pressure-derivation type vehicle body weighing apparatus to measure a vehicle load is characterized in that a pressure-derivation device communicates with a hydraulic oil cylinder device via a conduit; the hydraulic oil cylinder, a hydraulic control one-way valve, an electromagnetic directional valve, an overflow valve, a hydraulic pump and a oil tank form a hydraulic loop; a hydraulic oil cylinder set is connected to an oil circuit in parallel and is controlled by the electromagnetic directional valve; a hydraulic one-way valve is connected to an oil circuit at either side of the hydraulic oil cylinder; a pressure sensor is connected to 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 hydraulic ram or hydraulic ram group is placed on leaf spring or the vehicle bridge that pressure is derived weighting apparatus and is connected with hydraulic ram by the oil circuit pipe.When oil pump provides hydraulic pressure to hydraulic ram, the hydraulic ram jacking is until the body portion that holds up fully more than it, by pass valve is locked, the weight of vehicle body and the goods uploaded thereof is all carried by hydraulic ram, the weight squeezed fluid compressing cylinder of vehicle body and the goods uploaded thereof, thereby be converted into hydraulic pressure, pass to pressure by the oil circuit pipe and derive weighting apparatus.Pressure is derived and is imported micro controller system and signal crossover display terminal processing back demonstration after weighting apparatus is received pressure signal, promptly draws the load carrying ability of automobile.
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.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the hydraulic ram scheme of installation;
Fig. 3 derives the structural representation of weighting apparatus embodiment 1 for pressure;
Fig. 4 derives the structural representation of weighting apparatus embodiment 2 for pressure.
The specific embodiment
1 is hydraulic ram in the drawings, and 2 are pressure derivation weighting apparatus, and 3 is railway carriage, 4 is crossbeam, and 5 is the oil circuit pipe, and 6 are pressure conversion oil cylinder, 7 pistons for pressure conversion oil cylinder, 8 is pressure sensor, 9 are rotating shaft, 10 is lever, and 11 are the power transmission arm, and 12 is base, 13 is balance pivot, and 14 is hydraulic cylinder piston, and 15 is vehicle bridge, 16 is leaf spring, and 17 is the leaf spring backing plate.
In Fig. 1, pressure is derived weighting apparatus 2 and is connected with hydraulic ram 1 by oil circuit pipe 5.
In Fig. 2, hydraulic ram 1 places the side of crossbeam 4, is clipped between leaf spring backing plate 2 and the railway carriage 3, and is fixed on the leaf spring backing plate 17, also can be fixed on the railway carriage 3, and 17 for being the leaf spring backing plate.
In Fig. 3, oil circuit pipe 5 is communicated with pressure conversion oil cylinder 6, and the piston 7 of pressure conversion oil cylinder 6 is connected with pressure sensor 8.
In Fig. 4, oil circuit pipe 5 is communicated with pressure conversion oil cylinder 6, the piston 7 of pressure conversion oil cylinder 6 is connected with lever 10 by rotating shaft 9, balance pivot 13 is fixed on the base 12, and be connected with lever by rotating shaft, one end of lever 10 is provided with power transmission arm 11, and pressure sensor 8 is fixed on the base 12, below the power transmission arm 11.
Pressure sensor all is connected with micro controller system and signal indicator thereof.
Hydraulic ram, hydraulic control one-way valve, solenoid directional control valve, by pass valve, Hydraulic Pump, fuel tanks etc. are formed hydraulic circuit, a plurality of hydraulic rams are formed the hydraulic ram group and are connected in parallel on the oil circuit, by solenoid directional control valve control, all are connected in series a hydraulic control one-way valve on the both sides oil circuit of hydraulic actuating cylinder respectively.The effect of this hydraulic circuit provides hydraulic pressure to hydraulic ram exactly, makes the hydraulic ram jacking until the body portion that holds up fully more than it.Gravity is converted to hydraulic pressure, passes to pressure conversion oil cylinder, pressure conversion oil cylinder directly acts on pressure sensor with pressure, receives behind the pressure signal input micro controller system and signal crossover display terminal and handles the back and show, promptly draws the load carrying ability of automobile.
In the process of the installation of reality and use, a hydraulic ram and a corresponding pressure are derived weighting apparatus and are difficult to play the weighing effect, in the utility model, hydraulic ram, pressure are derived weighting apparatus can derive the weighting apparatus group by 2 to 8 hydraulic ram groups of forming and pressure.
