Problems solved by technology

Finally, after various researches and discussions, it was decided to adopt the method of continuous measurement to monitor and measure the pile legs for 24 hours, which consumes a lot of manpower and material resources. Only by analyzing the data step by step, the verticality data of the legs can be effectively controlled, but this method increases the cost, and there are certain errors in the data, which can be used in both cases, but it cannot be the final measurement method

Embodiment Construction

[0022] As shown in the figure, the rack 5 is installed on the frame 1 of the measurement and control frame through the bolt 2 and the nut 3, and the steel wire 6 is connected with the nut through the through hole 4.

[0023] The rectangular frame surrounds the rack on three sides, and the open side is connected to the surface around the legs. Bolts and nuts are respectively arranged on the outer end of the frame and the upper planes on both sides. Four through holes are arranged symmetrically.

[0024] The bolts are used to adjust the steel wires and control the straightness and verticality data of the pile legs.

[0025] The measurement method of the leg loading:

[0026] 1. Make the measurement and control frame. The inner width of the frame is 25mm larger than the width of the rack. Four through holes are opened on the frame for fixing the steel wires. Install nuts and bolts on the outer end, left and right ends of the frame respectively, and then install bolts to adjust t...

Abstract

The invention provides a measurement method for self-elevating type mobile platform spud leg erection. Frameworks of measurement and control frames are provided with a rack through bolts and nuts, andsteel wires are connected with the nuts via through holes. The method includes the following steps of: making the measurement and control frames, assembling spud legs, fixedly tying the steel wires to the through holes, measuring three-dimensional data on a rack side and analyzing actual measurement data. According to the measurement method of the invention, the measurement and control frames aredisposed at both sides of a closing port for erection of upper and lower spud legs, each set of the measurement and control frames corresponds to each other through the steel wires, the rack side linearity and verticality are measured to check and control linearity and verticality data of a whole spud leg, and spud leg erection high altitude construction three-dimensional data are measured, so that the measurement method can accurately analyze local problems, has simple measurement, is free of high altitude construction and hanger plate obstacles, saves huge labor costs, and has the advantageof high work efficiency. The measurement method is suitable to be used as the measurement method for the self-elevating type mobile platform spud leg erection.

Description

technical field [0001] The invention proposes a measurement method in the field of ship equipment installation, which is applied to the measurement of the accuracy control of pile legs on the dock. Specifically, it is the measurement method of the legs of the self-elevating mobile platform. Background technique [0002] The lifting mechanism of the self-elevating mobile platform is an important part of the lifting system of the self-elevating mobile platform. Its strength characteristics have an extremely important impact on the overall safety of the platform, and the strength of the entire lifting mechanism is determined by the lifting mechanism. Manufacture and installation accuracy are guaranteed. The entire lifting mechanism is composed of legs, racks, leg guide cylinders, mounting frames, lifting gear boxes and mounting wedge blocks. The leg guide tubes and mounting frames are welded together as the main structure connecting the legs and the main body of the platform. ...
