Embodiment Construction

[0046] The construction method of the base of the supporting and guiding device for the secondary cooling of the continuous casting machine will be described in detail below.

[0047] The method establishes a three-dimensional control network and uses a total station to align the base of the secondary cooling support and guide device, and specifically includes the following steps:

[0048] 1) Setting of three-dimensional coordinates, total station measurement;

[0049] ① see figure 2 , image 3 , Weld the measurement control point 3 symmetrically on the walls on both sides of the secondary cold support device, and set the permanent elevation point 1, the central mark plate 2, and the foundation embedded plate 4, and the burrs and sundries should be cleaned up.

[0050] ②According to the distance between the elevation point and the center line of the measured object relative to the base point, put the spherical prism (GPHIP) on the bolt cap, measure with TDA5005 total statio...

Abstract

The invention relates to a construction method of a base of a secondary cooling support oriented device of a continuous casting machine, comprising the following steps: using a total station instrument for centering the base of the second cooling support oriented device by establishing a tri-dimensional control net; obtaining tri-dimensional coordinate in an oriented section region through measuring by the total station instrument and calculating by a computer according to the distances of a spot height and a central line of a measured object relatively to a base point; determining the position for installing a device in a space tri-dimensional coordinate system, and ensuring the radius of curvature of device installation; and adopting anti-base grouting for constructing a baseboard of the secondary support oriented device. The invention has the advantages of reducing measurement and coordination personnel, lowering measurement error, reducing construction cost and improving the installation precision of the base of the secondary cooling support oriented device by establishing the tri-dimensional control net and using the total station instrument for centering the base of the secondary cooling support oriented device.

Description

technical field [0001] The invention relates to a construction method of large mechanical equipment, in particular to a construction method of a secondary cooling support guide device for a slab continuous caster in an iron and steel enterprise. Background technique [0002] In the steelmaking and continuous casting segment installation project, the key technology lies in the positioning of the base of the secondary cooling support guide device, which directly affects the accuracy of the arc alignment of the segment. In the past, the installation only used the method of hanging wires to cooperate with the measurement and adjustment of the base of the secondary cooling support and guide device. Each measurement required multiple cooperating personnel, and it was inconvenient to position the measuring instrument multiple times. Second, the adjustment of the base of the cold support guide device and the arc alignment accuracy of the sector. Contents of the invention [0003]...
