Problems solved by technology

However, there are still deficiencies in the application of this fixed electronic truck scale in the field of quantitative coal loading. Now the typical car loading process is as follows: the car is loaded by a loader or a coal feeder in a coal yard or a coal bunker, The personnel estimate the load, and then the car drives to the truck scale for weighing. When the car is overweight, the car needs to drive off the truck scale to a special unloading point for unloading, and then drive to the truck scale for weighing again; when the car is seriously loaded When it is insufficient, the car needs to drive off the truck scale to a special loading coal filling point for refilling, and then drive to the truck scale again for weighing
Such a loading process has resulted in repeated loading, low efficiency, poor loading quality, poor accuracy, and is very easy to cause environmental pollution
[0003] Patent No. 200920249702.8 is an automatic conveying truck scale. Its principle is to add a car conveying device on the weighing platform of the original conventional truck scale. The car conveying device drives the car on it to move from one end to the other. In the process of heavy loading, the whole process can be completed only by the single operation of the charging control personnel, so the automatic conveying truck scale overcomes the shortcomings of the fixed truck scale, avoids the process of adding and subtracting materials during the loading process, and has the advantages of loading and unloading. Fast, stable, accurate, high efficiency and other advantages; however, the weighing part of the lower part of the automatic conveying truck scale conveying device must meet the requirements of the length of the car and the moving distance, the weighing part and the conveying part are split, and the weighing part does not move with the conveying part , the total length of the automatic conveying truck scale is long, the installation space is large, the structure is complicated, the production is difficult, the manufacturing cost is high, and the spilled materials are easy to enter the gap between the conveying device and the weighing part, causing the conveying device to fail, and the failure rate High and difficult to maintain

Abstract

The invention belongs to car weighing and metering devices, and particularly relates to a mobile car automatic weighing platform. The mobile car automatic weighing platform comprises a weighing platform (5) and a walking mechanism, wherein the weighing platform (5) is arranged on the walking mechanism and is driven by the walking mechanism to move. According to the mobile car automatic weighing platform, a weighing platform board and a weighing sensor are arranged on the walking mechanism so that the weighing sensor and the weighing platform board can simultaneously walk along with the walking mechanism, and the entire loading process can be finished with the control under a single person when a car on the weighing platform board is loaded. Equipment can be installed for use without the need of modifying a road, and the whole equipment is convenient and rapid to install and detach, low in cost, and convenient to popularize and apply.

Description

technical field [0001] The invention belongs to a vehicle weighing and measuring device, in particular to a mobile vehicle automatic loading and weighing device. Background technique [0002] At present, the fixed electronic vehicle weighing technology, that is, the electronic truck scale with only weighing function has been widely used. The existing truck scale is generally composed of a load-bearing platform, a weighing frame, a load cell and a metering display device. The function is to weigh and measure, and some also have the functions of editing, storing and printing the weighing data. However, there are still deficiencies in the application of this fixed electronic truck scale in the field of quantitative coal loading. Now the typical car loading process is as follows: the car is loaded by a loader or a coal feeder in a coal yard or a coal bunker, The personnel estimate the load, and then the car drives to the truck scale for weighing. When the car is overweight, the...
