Description

Technical Field

[0001] The invention relates to the field of monitoring devices for powder tank trucks, in particular to a tank top pressure gauge device for powder tank trucks. Background Art

[0002] Existing powder tank trucks need to know the loading weight. One way is to weigh it on a scale to avoid overweight or to go to a dedicated scale to weigh it, which is time-consuming and costly. Another way is to install a vehicle-mounted weighing sensor device to weigh the vehicle. The sensor is installed on the main load-bearing part of the vehicle. The installation structure is complex and the production is troublesome. It will involve safety issues. The vehicle-mounted weighing sensor device is expensive, and the number of installed materials is large, which increases the weight of the vehicle. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a tank top pressure gauge device for a powder tank truck, which can measure the pressure of the frame air suspension airbag and establish an accurate correlation between it and the loading weight of the material in the tank, thereby realizing real-time monitoring of the loading weight of the powder tank truck, and at the same time presenting the weight information to the driver in a convenient manner, so as to better control the vehicle's load capacity and ensure transportation safety and efficiency.

[0004] To achieve the above object, the present invention provides the following technical solution: The tank top pressure gauge device of the powder tank truck of the present invention comprises the following main parts:

[0005] Tank top pressure gauge: This pressure gauge is connected to the frame air suspension airbag and is used to measure the pressure of the airbag. It uses a high-precision pressure sensor that can accurately sense small changes in pressure, convert the pressure signal into an electrical signal, and transmit the signal to the display module or subsequent processing unit through the internal circuit. The dial design of the pressure gauge should be easy to read and the scale should be clear, so that the operator can check the pressure value at the vehicle operating position.

[0006] Air pipe connection components:

[0007] Air pipe: including nylon air pipe (black) φ6*1mm and black corrugated pipe. These air pipes are channels for pressure transmission, which have good elasticity and sealing, can work stably under different environmental conditions, and ensure that the pressure signal is not interfered by the outside world during the transmission from the airbag to the pressure gauge.

[0008] Air pipe quick elbow, air pipe quick connector, C-type self-locking connector (male end), C-type self-locking connector (female end): These components are key elements of air pipe connection. Through reasonable layout and connection, the air pipe can be extended to the air suspension airbag along the tank top guardrail column connecting pipe, ladder, and frame fixed wire pipe. The quick elbow can change the direction of the air pipe, and the quick connector and C-type self-locking connector ensure the firmness and operability of the connection, avoid pressure leakage, and facilitate installation and disassembly, maintenance and replacement of parts.

[0009] Installation structure: It is composed of a pressure gauge mounting plate, which is designed according to the structural characteristics and mechanical requirements of the tank top and uses high-strength materials to ensure that it can withstand vibration and other external forces during vehicle driving. The tank top pressure gauge is installed on the inner side of the column connecting pipe through the mounting plate. The shape of the mounting plate and the selection of the mounting position not only ensure the stability of the pressure gauge, but also take into account the convenience of observation by the operator, so that the operator can easily see the pressure gauge reading from the cab or other operating positions.

[0010] Pressure value and load weight correspondence system:

[0011] Establishment of the corresponding value table: Before using this device, it is necessary to establish the corresponding relationship between the pressure value and the load weight. This is achieved through a calibration process, the specific steps are as follows:

[0012] The whole vehicle is placed on the company's internal scale and water is added to the tank. First, water is added to 80% of the rated load mass, and the pressure value displayed by the tank top pressure gauge is recorded using a high-precision measuring instrument.

[0013] After that, continue to add water to the tank in increments of 2% of the rated load mass, and record the pressure value of the corresponding tank top pressure gauge each time the water mass in the tank reaches the rated load mass. In this way, at least 20 sets of different pressure and load weight data are obtained, and these data are organized into a corresponding value table of pressure values ​​and load weights; this value table can be stored in the vehicle's electronic system, or posted inside the cab in paper form for easy viewing by operators.

[0014] When establishing the correspondence, a variety of environmental factors are taken into account, such as different temperatures, altitudes, etc. Through complex algorithms and experiments, the accuracy and reliability of the correspondence under different conditions are ensured.

[0015] Data processing and display module: This module receives the pressure signal from the tank top pressure gauge and converts the pressure signal into the corresponding load weight information according to the pre-stored corresponding value table; this information can be displayed in digital form on the display screen in the cab, or the driver can be informed by voice prompts, or the information can be transmitted to the vehicle's central control system to achieve integration with other vehicle systems.

[0016] Beneficial effects: The present invention can monitor the load weight in real time without the need to go to a scale for weighing or to install a weighing sensor in a complicated way, thus saving time and cost and improving transportation efficiency;

[0017] The installation structure is stable and easy to observe, the air pipe connection components have reliable performance, the pressure value and loading weight correspondence system is accurate, and it can adapt to a variety of environments, providing strong guarantee for the safe transportation of powder tank trucks.

[0032] Pressure value and load weight correspondence system:

[0033] Establishment of the corresponding value table: Before using this device, it is necessary to establish the corresponding relationship between the pressure value and the load weight. This is achieved through a calibration process, the specific steps are as follows:

[0034] The whole vehicle is placed on the company's internal scale and water is added to the tank. First, water is added to 80% of the rated load mass, and the pressure value displayed by the tank top pressure gauge is recorded using a high-precision measuring instrument.
