背景技术Background technique
船模水动力性能测试是指利用物理模型方法，确定船模性能研究和船舶设计中所要求的有关数据及资料的一种手段，它可以对船舶的综合航行性能进行系统的估算和评估。通过船模试验，不仅可以研究新的船型，探讨影响船舶航行性能的各种因素，而且可以对船舶在航行中所发生的物理过程获得更深刻的理解。The hydrodynamic performance test of the ship model refers to a means of determining the relevant data and information required in the study of ship model performance and ship design by using the physical model method. It can systematically estimate and evaluate the comprehensive navigation performance of the ship. Through the ship model test, not only can new ship types be studied, and various factors affecting the ship's navigation performance can be explored, but also a deeper understanding of the physical process that occurs during the ship's navigation can be obtained.
它可以促进理论工程进一步发展，使工程计算中所应用的计算方法不断的完善，提高理论研究和工程设计能力，改进船舶的航行性能。因此，世界上造船工业比较发达的国家，无不重视船模试验池的建设并相应的发展各种船模水动力性能测试装置。It can promote the further development of theoretical engineering, continuously improve the calculation methods used in engineering calculations, improve theoretical research and engineering design capabilities, and improve the navigation performance of ships. Therefore, countries with relatively developed shipbuilding industries in the world all pay attention to the construction of ship model test pools and develop various ship model hydrodynamic performance test devices accordingly.
对于大跨度重型轮式船模试验拖车而言，其在两条固定式钢轨上面行走时，两侧车轮随着时间运行会产生累计偏差，即两侧车轮运行不同步，这样轻则会导致出现故障、重则导致出现重大事故。为了解决这种不同步的现象，解决方法之一是在两侧钢轨旁边加设两条线性定位编码器系统。For a large-span heavy-duty wheeled ship model test trailer, when it walks on two fixed rails, the wheels on both sides will have accumulated deviations over time, that is, the wheels on both sides will not run synchronously. Faults and serious accidents can lead to major accidents. In order to solve this asynchronous phenomenon, one of the solutions is to add two linear positioning encoder systems next to the rails on both sides.
但是大跨度重型轮式船模试验拖车的结构会随着温度变化发生很大热胀冷缩，这就导致这些大跨度重型轮式机械会发生垂直于钢轨方向的移动，使得线性编码器的读数头与测量码带发生左右错位，使得读数头不能够感应出测量码带上面的数据。However, the structure of the large-span heavy-duty wheeled ship model test trailer will undergo great thermal expansion and contraction with temperature changes, which will cause these large-span heavy-duty wheeled machinery to move perpendicular to the direction of the rail, making the reading of the linear encoder The left and right misalignment of the head and the measuring code tape makes the reading head unable to sense the data on the measuring code tape.

工作原理working principle
本申请实施例提供了一种可调式线性定位编码器及船模试验拖车，由于本申请的可调式线性定位编码器设置了测量码带固定座，该测量码带固定座位于钢轨19的一侧且沿钢轨19的长度方向延伸，测量码带固定座上固定设有沿测量码带固定座的长度方向延伸的测量码带2；读数头调节器，该读数头调节器包括与船模试验拖车连接的支座6，支座6与钢轨19之间滑动连接有伸缩杆7，支座6上设有推动伸缩杆7朝钢轨方向移动的第一驱动件8，伸缩杆7上设有与测量码带2适配的读数头12。The embodiment of the present application provides an adjustable linear positioning encoder and a ship model test trailer. Since the adjustable linear positioning encoder of the present application is provided with a measuring code belt fixing seat, the measuring code belt fixing seat is located on one side of the steel rail 19 And extend along the length direction of steel rail 19, the measuring code band 2 that extends along the length direction of measuring code band fixing seat is fixed on the measuring code band fixing seat; Connected support 6, a telescopic rod 7 is slidably connected between the support 6 and the rail 19, the support 6 is provided with a first driver 8 that pushes the telescopic rod 7 to move towards the direction of the rail, and the telescopic rod 7 is provided with a measuring Readhead 12 for code tape 2 adaptation.
因此，本申请的可调式线性定位编码器当大跨度重型轮式船模试验拖车沿着钢轨19运行时，随着温度的影响，结构发生了热胀冷缩，导致安装有可调式线性定位编码器的结构发生了左右运动。当发生向右运动时，支座6会向右运动，但是在第一驱动件8的作用下，使得伸缩杆7向左运动，使得伸缩杆7一直与钢轨19侧面贴合，最终使得读数头12与测量码带2的位置保持不变。当发生向左运动时，支座6会向左运动，第一驱动件8使得伸缩杆7一直与钢轨19侧面贴合，但是伸缩杆7不发生左右运动，最终使得读数头12与测量码带2的左右位置保持不变，使得读数头12始终能够感应出测量码带2上面的数据。Therefore, when the adjustable linear positioning encoder of the present application runs along the steel rail 19 with the large-span heavy-duty wheeled ship model test trailer, the structure will expand with heat and contract with cold due to the influence of temperature, resulting in the installation of an adjustable linear positioning encoder. The structure of the organ moves side to side. When moving to the right, the support 6 will move to the right, but under the action of the first driving member 8, the telescopic rod 7 will move to the left, so that the telescopic rod 7 is always attached to the side of the rail 19, and finally the reading head 12 and the position of the measuring tape 2 remain unchanged. When moving to the left, the support 6 will move to the left, and the first driving member 8 will make the telescopic rod 7 stick to the side of the rail 19 all the time, but the telescopic rod 7 will not move left and right, and finally the reading head 12 will be in contact with the measuring code tape. The left and right positions of 2 remain unchanged, so that the reading head 12 can always sense the data on the measurement code tape 2.
