Description
Technical field
The utility model is related to weighing device technical field, specifically a kind of cargo transport vehicle is weighed ground pressure-sensitive power
Sensing device.
Background technology
Lorry is the important vehicles for transporting cargo, wherein needs to weigh to freight wagon sometimes.
Usual freight wagon is mainly weighed using ground pressure-sensitive Force sensor, currently, existing freight wagon
It weighs ground pressure-sensitive Force sensor, is usually made of several sensors, but can all increase per a sensor is increased more
The error of measurement, such as the vibration that vehicle generates in pavement roughness can cause measuring signal to change when passing through sensor,
In addition, per a sensor is increased, it can all increase a sensor wire, sensor wire quality, environment resistant interference performance more
Also the error integrally measured can be influenced, therefore, existing sensor needs to be improved there are the not high defect of measurement accuracy.
Utility model content
Purpose of the utility model is to solve the not high defects of inconvenient for use, measurement accuracy in the prior art, carry
Ground pressure-sensitive Force sensor is weighed for a kind of cargo transport vehicle to solve the above problems.
To achieve the goals above, the technical solution of the utility model is as follows：The utility model discloses a kind of cargo fortune
Defeated vehicle weighing ground pressure-sensitive Force sensor, including weight bearing foundation, a fixed sensor mounting plate on the weight bearing foundation,
The lower surface of sensor mounting plate and the upper surface of weight bearing foundation fits, and is opened on the weight bearing foundation there are one line
Cable mounting hole installs a pressure sensor on the sensor mounting plate, and the pressure sensor is through sensor peace
Above and below loading board, the shape of the pressure sensor is rectangular-shape, and upper surface and the sensor of the pressure sensor are pacified
The upper surface flush of loading board.
Preferably, the shape of the weight bearing foundation is rectangular groove body type, the lower end of the pressure sensor is being held
In weight pedestal.
Preferably, the fixed reinforcement connecting plate of left and right ends difference inside the weight bearing foundation, described adds
The upper end of strong ties plate is connected with the lower surface of sensor mounting plate.
The utility model has the following advantages compared with prior art：
Cargo transport vehicle described in the utility model weigh ground pressure-sensitive Force sensor by using rectangular-shape pressure
Force snesor increases forced area, improves the validity of detection, and stability reduces the error weighed, while using one
The design of the pressure sensor of a rectangular-shape reduces cable mounting hole, only needs a cable mounting hole, reduces because of sensing
Error caused by device circuit question, while also improving cargo transport vehicle and weighing ground pressure-sensitive Force sensor in complex condition
Environment resistant interference performance.
Description of the drawings
Fig. 1 be a kind of cargo transport vehicle of the utility model weigh ground pressure-sensitive Force sensor schematic cross-sectional view；
Fig. 2 be a kind of cargo transport vehicle of the utility model weigh ground pressure-sensitive Force sensor structural schematic diagram.
Wherein：1- weight bearing foundations；2- sensor mounting plates；3- cable mounting holes；4- pressure sensors；5- reinforces connection
Plate.
Specific implementation mode
To make the structure feature to the utility model and the effect of being reached has a better understanding and awareness, to compared with
Good embodiment and attached drawing cooperation detailed description, are described as follows：
As shown in Figs. 1-2, the utility model discloses a kind of cargo transport vehicle weigh ground pressure-sensitive Force sensor, including
Weight bearing foundation 1, a fixed sensor mounting plate 2 on the weight bearing foundation 1, the lower surface of the sensor mounting plate 2
It fits, is opened on the weight bearing foundation 1 there are one cable mounting hole 3, the sensor is pacified with the upper surface of weight bearing foundation 1
One pressure sensor 4 is installed, the pressure sensor 4 runs through about 2 sensor mounting plate, the pressure in loading board 2
The shape of sensor 4 is rectangular-shape, the upper surface flush of the upper surface and sensor mounting plate 2 of the pressure sensor 4.
Pressure sensor 4 is shaped to rectangular-shape, increases forced area, improves the validity of detection, surely
Qualitative, load-bearing precision significantly improves, and reduces the error weighed, while only with the pressure sensor of a rectangular-shape
4 design reduces cable mounting hole 3 and wire rod, and a cable mounting hole 3 installs cable eaily simultaneously,
Reduce the error caused by sensor line problem, at the same also improve cargo transport vehicle weigh ground pressure-sensitive Force sensor
In the environment resistant interference performance of complex condition.
Preferably, the shape of the weight bearing foundation 1 is rectangular groove body type, the lower end of the pressure sensor 4 exists
In weight bearing foundation 1.
Weight bearing foundation 1 is set as rectangular groove body type, and the lower end of pressure sensor 4 plays guarantor in this way in weight bearing foundation 1
The effect for protecting pressure sensor 4 prevents naked be exposed on the external in lower part of pressure sensor 4 and the defect that is easily damaged, service life
It greatly prolongs.
Preferably, the fixed reinforcement connecting plate 5 of left and right ends difference inside the weight bearing foundation 1, described
The upper end for reinforcing connecting plate 5 and the lower surface of sensor mounting plate 2 are connected.
Reinforce connecting plate 5 by setting, reinforces connecting plate 5 and play the role of reinforcing sensor mounting plate 2, whole stabilization
Property also just significantly improve, service life extend while, weighing precision also just significantly improves.
Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
