Three-stage compound weighing device

Abstract

The invention belongs to the field of expressway automobile weighing scales, and in particular relates to a three-stage composite weighing platform. The three-section composite weighing platform is composed of the first section, the second section, the third section, and the weighing sensor under the weighing platform. It is characterized in that, from left to right, the first section The rear end of the weighing platform is lapped on the front end of the second section of the weighing platform, the front end of the third section of the weighing platform is lapped on the rear end of the second section of the weighing platform, and the upper surface of the whole scale body is level and even. The recent application practice has proved that the beneficial effect of the three-stage composite weighing platform is that the investment is small, that is, it does not need to spend a lot of money to build a huge static scale, which is almost the investment basis of the axle load scale. The construction period is short, cheating prevention, quick results, and income Large, realize dynamic fast and accurate weighing, benefit the country and the people. The advantage of "low investment and dynamic, rapid and accurate weighing" makes the three-stage composite weighing device expected to replace the traditional large static scale and simple axle load scale, and is suitable for installation and use at the entrance of all congested roads.

Description

technical field [0001] The invention belongs to the field of expressway automobile weighing scales, and in particular relates to a three-stage composite weighing device. Background technique [0002] Known high-speed road car weighing scale, a kind of is static scale, and another kind is axle load scale. The advantage of static scales is that they can be weighed accurately. The main features are as follows: Static weighing platform, the length of the weighing platform needs to be able to hold a whole vehicle, and the general length is 17-21 meters. Each time the weight is weighed, the vehicle needs to be parked on the static weighing platform, and one vehicle is released with one pole, and one vehicle is weighed at a time. Since the static weighing platform is a whole with a huge length, the disadvantages of the static weighing platform are high cost, inconvenient installation and transportation, and slow weighing speed, which may cause congestion of vehicles at the entran...

Problems solved by technology

The disadvantage is that the weighing accuracy is poor, and there may be drivers of heavy-duty vehicles who cheat artificially, such as braking when driving on the weighing platform, walking in an S shape, etc.
