Problems solved by technology
However, in the process of operation, there will generally be accumulated material in the weighing hopper and the loading leak pipe, etc., and the actual material loaded into the truck box cannot be determined. In addition, the accuracy of the weighing hopper measurement is difficult to verify and adjust, which makes it impossible to judge Accuracy of weighing scale
In actual work, it can only be ensured that most of the loading weight is controlled within the allowable overload range of the railway, and some carriages are overweight or underweight; now there is an automatic detection device and method for the height of transported materials, which can be compared Accurately measure whether the height of the material meets the standard, but cannot calculate the volume of the material; in addition, there are some test devices and methods for testing the volume of the mine, the volume of concrete, and the volume of accumulated materials, but they are often costly and difficult to operate , with limited application

Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] figure 1 and figure 2 A schematic diagram of a preferred embodiment of the invention is shown. At first choose suitable place to install gantry column 4 and crossbeam 2, and described column 4 spacing is greater than rail spacing and compartment 6 width. The height of the beam 2 from the ground is always higher than the top surface of the material 5 and the height of the compartment 6 . Then a plurality of laser range finders 1 are embedded in the crossbeam 2, and the lasers 3 emitted by the same horizontal row of laser range finders are in the same vertical plane, and the laser range finders on both sides are precisely installed according to the outline of the carriage, so that they can be measured exactly Get the material information on both sides of the carriage boundary, and number the laser range finder, numbering from left to...

The invention discloses a device and a method for measuring a vehicle loading capacity by a laser ranging technology. A door-shaped frame cross beam is provided with a plurality of laser rangers, thelaser rangers and a host computer are in wireless data communication, the laser rangers continuously measure the each-point information of carriage loading materials which pass below the laser rangers, and transmit the information to the host computer, and the host computer carries out fitting to obtain the material curved surface of each carriage and calculates a material capacity. By use of thedevice and the method, the material capacity of each carriage and the total capacity of the materials of the vehicle can be accurately calculated, and the problem that parts of carriages are subjectedto overloading or short weight can be effectively solved. In addition, the device and the method have the advantages of being simple in operation, low in cost, high in accuracy degrees and wide in application range.
Description
technical field [0001] The invention relates to the calculation of the volume of materials transported by vehicles, in particular to a device and method for measuring the volume of vehicles loaded by using laser ranging technology. Background technique [0002] At present, in metallurgy, mining, power generation and many other fields, the most important means of material transportation is the train. The amount of material transported by train plays a very important role in the safety and economy of train transportation. At present, the loading device of the train, such as the loading building, can complete the loading of the train, and can also calculate the material volume according to the static method of the weighing bucket, which can theoretically meet the requirements of commercial measurement. However, in the process of operation, there will generally be accumulated material in the weighing hopper and the loading leak pipe, etc., and the actual material loaded into the...
