Problems solved by technology

One is visual inspection, that is, managers use their eyes to observe the deflection of the bogie spring group, and then use their own experience to estimate the load capacity of each car and whether it is unbalanced. The second is to use a jack to lift up the eight wheels of each carriage, and then use a tonnage meter to measure the load capacity of each carriage.
Although this method can achieve measurement accuracy, the operation is complicated, the labor intensity is high, and the detection process takes a long time, which especially affects the efficiency of railway freight.

Embodiment Construction

[0024] The method for detecting the carrying weight of railway freight cars is to use a portable railway freight car overweight and partial load detector to detect the deflection f of the four groups of spring groups of the two bogies respectively 1 , f 2 , f 3 , f 4 . The bogie is type 8A. Spring stiffness K=540 / mm.

[0025] Measured: f 1 =16.11mm

[0026] f 2 =20.82mm

[0027] f 3 =15.98mm

[0028] f 4 =20.28mm

[0029] Then there is: P 1 = f 1 ·K=8.70 tons

[0030] P 2 = f 2 ·K=11.24 tons

[0031] P 3 = f 3 ·K=8.63 tons

[0032] P 4 = f 4 ·K=10.95 tons

[0033] P=P 1 +P 2 +P 3 +P 4 = 8.70 tons + 11.24 tons + 8.63 tons + 10.95 tons = 39.52 tons

[0034] That is, the load capacity of railway wagons is 39.52 tons.

Abstract

The invention relates to a method for detecting lorry load capacity, having the property of by detecting deflection of four groups of cylindrical helical spring pack under two swing blosters in lorry and using formula calculate load capacity of lorry; P in the formula is load capacity of lorry, p1, p2, p3, p4 are separately weights of load of the four cylindrical helical spring packs o, k is spring constant and x is 1 or 2, 3, 4. The method can detect load capacity of lorry conveniently, accurately and easy to be expanded.

Description

(1) Technical field [0001] The invention relates to a method for detecting the load of a freight vehicle, in particular to a method for detecting the carrying weight of the freight vehicle by detecting the deflection of a cylindrical helical spring group under a bolster of a railway freight car and a vibration-damping cylindrical helical spring. (2) Background technology [0002] With the rapid development of our country's national economy, the prosperity of commerce and the improvement of people's living standards, the rapid development of the transportation industry has been promoted, and the pressure on railway freight is increasing. The two basic problems to be solved by the current railway freight are to realize safe transportation and improve freight efficiency, and overweight or unbalanced load is one of the key issues affecting safe operation. Therefore, railway freight management personnel should carry out overweight and unbalanced load detection on railway freight ...
