Description

Technical Field

[0002] The fan-shaped segment foundation frame is an important part of the continuous casting machine and an important guarantee for the slab continuous casting machine to smoothly produce qualified castings. The difficulty of installing the fan-shaped segment foundation frame lies in the high installation accuracy requirements. The installation accuracy of the main dimensions reaches ±0.15mm, and the entire installation measurement is carried out in three-dimensional space. To ensure that the spatial dimensions and positions of each part are correct and accurate, reasonable measurement equipment and optimized measurement methods must be adopted, and special auxiliary measurement tools need to be used for coordinated measurement.

[0003] In the design drawings of the fan-shaped segments of the continuous casting machine, four processing surfaces are usually set on the top of the base frame of each fan-shaped segment to position the fan-shaped segment, of which two processing surfaces are planes, one processing surface is conical, and the other processing surface is inverted trapezoidal. When aligning the equipment, it is necessary to measure and locate the spatial dimensions of each processing surface to determine the position and elevation of the center point of the processing surface. This process is also the process of aligning the base frame and the fan-shaped segment. This requires multi-point measurement of each processing surface by a total station, and then using analysis software to fit the center coordinates of the graphics to determine the position and elevation of the center of each processing surface of the base frame. Such a measurement process is very cumbersome and the accuracy is not high. In particular, it is very difficult to determine the center position of the conical slot and the inverted trapezoidal slot positioning surface, which increases the difficulty of positioning the fan-shaped segment. In order to simplify the measurement process and improve work efficiency, a measuring device for the base frame of the fan-shaped segment of the continuous casting machine is needed to solve the above technical problems.

[0005] The technical solution adopted in the embodiment of the utility model is: a measuring device for a base frame of a continuous casting machine fan-shaped segment, which can be connected to the base frame and a total station, and a plurality of processing surfaces are provided on the top of the base frame, which is characterized in that it includes a spherical prism, a top support for supporting the spherical prism, the top support is connected to a connecting member through a supporting member, and the side of the connecting member away from the supporting member is clamped with the processing surface.

[0009] Furthermore, the jacking support is a hollow sleeve, wherein the axis thereof coincides with the center line.

[0010] Furthermore, the end of the support away from the support member is chamfered to support the spherical prism and rotate it while keeping the center unchanged.

[0018] The embodiment of the utility model provides a measuring device for a sector base frame of a continuous casting machine, which is described below in conjunction with the accompanying drawings.

[0019] Reference Figure 1As shown, a measuring device for the base frame of the fan-shaped segment of a continuous casting machine can be connected to the base frame 1 and the total station 2. The top of the base frame 1 is provided with multiple processing surfaces, including a spherical prism 3, a top support 4 for supporting the spherical prism 3, and the top support 4 is connected to the connecting member 6 through a support member 5. The side of the connecting member 6 away from the support member 5 is clamped with the processing surface. The center of the spherical prism 3 is located on the center line 7 of the processing surface, and the center line is perpendicular to the processing surface 8. An opening is provided on the spherical prism 3, and a three-sided reflecting prism is provided in the opening, and the opening is aligned with the total station. The center of the three-sided reflecting prism coincides with the center of the spherical prism 3. The top support 4 is a hollow sleeve, and the axis thereof coincides with the center line. The end of the top support 4 away from the support member 5 is provided with a chamfer to support the spherical prism 3 and keep the center unchanged while allowing it to rotate. The connecting member 6 is in the shape of a truncated cone, and its cross section is an inverted trapezoidal structure. The inclined surface of the inverted trapezoidal structure fits tightly with the periphery of the processing surface, and the bottom size of the connecting member 6 matches the processing surface 8, so that the connecting member 6 and the processing surface 8 are fixed to each other. The processing surface 8 includes but is not limited to a plane, a V-shape and an inverted trapezoid. In this embodiment, the processing surfaces are evenly distributed on the top of the base frame 1, and are respectively two planes, a V-shaped surface, and an inverted trapezoidal surface. The V-shaped surface here refers to a conical groove opened in the center of the processing surface so that the cross section of the processing surface is V-shaped. Similarly, the inverted trapezoidal surface here refers to an inverted trapezoidal groove opened in the center of the processing surface so that the cross section of the processing surface is an inverted trapezoid.

[0020] In this embodiment, the top of the base frame 1 is provided with four processing surfaces, two of which are planes, one is V-shaped, and one is an inverted trapezoid. Figure 1 As shown, taking the inverted trapezoidal processing surface as an example, after the base frame is installed, the connector 6 is placed in the groove, the side slope of the connector 6 contacts the slope of the processing surface, and the bottom of the connector 6 contacts the bottom of the groove, so that the connector 6 and the processing surface 8 are fixed to each other. At this time, the center of the spherical prism coincides with the center of the three-sided reflective prism and is located on the center line 7, and the center position of the processing surface 8 is quickly determined. During the rotation of the spherical prism 3, the center of the spherical prism 3 is kept stationary, and the window of the spherical prism 3 is facing the total station. At this time, the total station cooperates with the spherical prism 3 and the three-sided reflective prism to accurately measure the elevation of the center position, measure all processing surfaces in turn, and continuously adjust the position of the base frame until the installation accuracy of the base frame meets the design requirements, that is, matches the fan segment.

[0021] Taking the V-shaped processing surface as an example, when the connecting member 6 is put in, it is stuck in the V-shaped groove, which can also achieve mutual fixation between the connecting member 6 and the processing surface 8.

[0022] If the processing surface is flat, the connecting member 6 can be directly placed on the plane. The bottom of the connecting member 6 matches the processing surface, and the elevation of the center position can be directly measured by the total station.

[0023] The advantages and positive effects of the utility model are: making full use of the principle of keeping the center positioning of the spherical prism unchanged, and then using the T-shaped positioning principle of the auxiliary tool to perform measurement, so as to achieve the purpose of accurate measurement accuracy; the auxiliary tool and the spherical prism are simple to make and can be used repeatedly; the operation is simple, and the method of use can be mastered quickly, making installation and alignment more convenient and quick; it saves manpower and material resources, and implements green and environmentally friendly construction, thereby achieving cost reduction and efficiency improvement.

[0024] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
