TECHNICAL FIELD
[0001] The present application belongs to the field of offshore ship design and construction, and particularly relates to a mobile trolley for detecting the movement of containers based on total station data. BACKGROUND
[0002] During the loading stage in the container ship building dock, the cargo hold is shaped and welded, and then accessories are installed in the hold. After the installation is completed, entity test box work is carried out in the cargo hold to determine whether the 20 or more box positions in the cargo hold can be smoothly loaded, and whether the matching data of the guide rails in the box positions and the accessories meet the design requirements. Before the installation of the accessories, the data matching of the accessories and the guide rails needs to be detected to ensure that the container can be smoothly placed in the center of the pile after falling, and not in contact with the angle steel surface of the guide rail, and to ensure that the data is within the tolerance range. In the past construction, the construction personnel could only use a plumb line to detect the matching data of the lowermost guide rail connecting plate and the accessories, and the upper part could not be detected. The remaining part could only be detected by erecting a scaffold in the cargo hold. In the current construction process, the scaffold is no longer erected in the hold according to the requirements of safety production and paint protection, which adversely affects the detection of data and poses great difficulties in the detection method. The use of the non-light target mode seriously affects the accuracy of the data, and the remaining part of the guide rail data can only be judged whether it meets the design standard through subsequent entity test box self-checking, which greatly increases the construction cost and efficiency. In order to achieve the detection of the accuracy data of all the guide rail data in the cargo hold without the erection of the scaffold, the existing resources and technical systems need to be optimized to achieve greater functional improvement. Therefore, a climbing auxiliary detection device for detecting the container ship based on the total station is designed. The use of the total station and the device together for the accuracy data measurement of the guide rail data in the hold can greatly improve the construction efficiency and accuracy, and can facilitate the measurement of the construction to achieve one-time feedback of the accuracy data (X, Y). The design of the detection method and device solves the problem that the vertical guide rail data cannot be detected after the cargo hold is shaped. It also solves the problem of low efficiency and increased construction cost of the entity test box in the cargo hold. When using the detection method and device, the total station is first erected at any position, and the device is placed on the guide rail. The up-down movement of the remote control device and the rotation angle of the light target are used to make the turning instrument face the angle between the device and the instrument for accuracy measurement and construction. The detection can be carried out at different positions during the implementation process. SUMMARY
