Embodiment Construction

[0020] The adjustment method and process of the installation position error of the entire T-shaped structure truss will be described in detail below in conjunction with the accompanying drawings.

[0021] The specific implementation steps of the adjustment method of the T-shaped structure truss installation position error proposed by the present invention are as follows:

[0022] 1. Based on the measurement data, establish a geometric model for position error analysis of point E of the main truss.

[0023] Such as image 3 with 4 As shown, the position error of the point E of the main truss is the joint result of the installation angle deviation of the cross truss 10' deviating from the ideal position and the installation angle deviation of the vertical truss 9' deviating from the ideal position. Using the principle of vector synthesis, the installation angle deviation of the cross truss 10' is decomposed into the rotation around the X axis and the rotation around the Y axis...

Abstract

The invention discloses a method for adjusting installation position error of a T-shaped truss, including the following steps: (1) primarily placing the T-shaped truss; (2) accurately measuring installation angular deviations alpha 1, alpha 2, alpha 3 and alpha 4 of a cross truss and a vertical truss in a horizontal direction and a vertical direction respectively, and a vertical distance L from apoint E to the vertical truss; (3) calculating a horizontal cycle error delta r of the point E; and (4) checking whether the horizontal cycle error delta r of the point E satisfies installation requirements, adjusting values of the alpha 1, the alpha 2 and the alpha 3, and then returning to the step (2) to continue operations until the delta r satisfies the installation requirements. The method creates a truss position error analyzing model, the adjusting method is simple and effective, and demands on high precision installation of the truss structure in practical projects can be satisfied. The method can be used for precision adjustment for a large truss structure guide rail transportation device which has demands on high precision and can be temporarily installed and detached.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a method for adjusting the installation position error of a T-shaped structure truss. Background technique [0002] The "underwater delivery and operating system" (HDS for short) of the radiation supervision tube in the nuclear power plant reactor is a large-scale, high-precision equipment for high-radiation underwater maintenance in the nuclear power plant reactor. The system is detachable, and it is transported to the site for assembly during the maintenance of the nuclear power plant reactor. After assembly, it is installed on the crane tube with the nuclear reactor core. The system completes all underwater maintenance tools, lighting monitoring systems, operating arms, Delivery of measuring tools and parts. The correctness of the underwater maintenance operation greatly depends on the overall accuracy adjustment level of the HDS system. [0003] The main tru...
