A vehicle fuel tank weighing device

Abstract

The invention belongs to the field of measuring instruments and relates to a vehicle-mounted weighing device, in particular to a vehicle-mounted tank weigher, comprising a bottom mounting plate. A fixing support with upper horizontal arms is disposed on the bottom mounting plate. Spring mechanisms are disposed on two sides of the fixing support on the bottom mounting plate. A weighing table is disposed on each spring mechanism. An adjustable height tank carrier is connected to the upper horizontal arms of the fixing support through a plurality of long screws. A fuel tank is disposed on the adjustable height tank carrier. The adjustable height tank carrier allows the weigher to run at divided times; during a vehicle running, the weighing tables are separated from the fuel tank, the weigher is idle, and impact vibration caused by weight of the fuel tank is never applied to a weighing sensor table; before weighing, the long screws are adjusted to allow the fuel tank to be in contact with the weighing tables, the weigher runs in a short time only, and the vehicle stops and is insusceptible to impact vibration, the weighing tables are well protected, and the service life of the weigher is effectively prolonged.

Description

technical field [0001] The invention belongs to the field of measuring instruments, and relates to a vehicle-mounted weighing device, in particular to a vehicle-mounted fuel tank weighing device. Background technique [0002] With the development of engineering vehicles in the direction of intelligence, more and more engineering transport vehicles need to install weighing equipment to monitor the consumption of fuel tanks (water tanks) to provide information for safe driving, especially for large vehicles operating in the field. Fuel supply is inconvenient, and the remaining fuel in the fuel tank needs to be accurately known at any time. The traditional measurement method is to measure the liquid level through an oil float, which is an indirect measurement of the weight of the oil, and the accuracy is very low. In addition, in the alpine region, the oil float cannot work because the oil becomes viscous or frozen, and this method will directly fail , so the on-board weighing...

AI Technical Summary

Problems solved by technology

Since engineering vehicles are mostly in the field environment and are frequently in the state of transportation, the weighing device is in a vibrating environment for a long time, especially when the road conditions are poor. It is difficult for the rubber layer of the rubber layer to provide long-term and effective buffering for long-term alternating loads, which will easily lead to excessive zero drift of the strain gauge load cell, creep instability and other faults, and eventually make the vehicle weighing device's accuracy drop or even unusable
