超长货物在运输中使用的横垫木或货物转向架的高度,是超长货物运输中的重要问题之一。欠高则危及行车安全和货物完整,过高则增大重车的重心高度和货物的超限程度或等级,降低线路通过能力,提高货物运输费用。本文研究了影响起长货物横垫木和货物转向架高度的各项因素。指出现行计算公式中a及tgr的取值不当,不符合经济合理的原则。提出了确定横垫木及货物转向架合理高度的计预公式。
One of the most important issues in the long cargo transport is the height of the horizontal bolsters or freight bogies used in the transport of long cargoes. Under-high is endangering traffic safety and cargo integrity. Too high will increase the center of gravity of the heavy truck and the over-limit or grade of the cargo, reducing the capacity of the route and increasing the cost of freight transportation. This article examines the various factors that affect the height of long-haul logs and freight bogies. Pointed out that the current value of a and tgr in the calculation of inappropriate values, does not meet the economic and reasonable principles. Proposed pre-formula to determine the reasonable height of horizontal bogie and cargo bogie.
