Description

Installation method and installation device for threaded sleeve of rolling mill Technical Field The invention belongs to the technical field of building construction and equipment installation, and particularly relates to an installation method and an installation device for a threaded sleeve of a rolling mill. Background In the fields of metallurgy, heavy machinery and large industrial equipment, a rolling mill is used as core production equipment, and the installation accuracy of the rolling mill is directly related to the running stability of the equipment, the processing quality of products and the service life of the products. The rolling mill is usually rigidly connected to the concrete foundation by means of high-strength threaded sleeves (also known as high-strength bolt sleeves), which are pre-embedded in the equipment foundation, to which the rolling mill base is subsequently anchored by high-strength bolts. Therefore, the installation position precision of the threaded sleeve, including plane coordinates, top surface elevation and verticality, becomes a key control point of the whole rolling mill installation engineering. However, in the prior art, the installation of the threaded sleeve commonly adopts a traditional manual method, namely, firstly, a measurer uses a total station or a theodolite for lofting and positioning, then, the sleeve is fixed through a temporary support welded by angle steel and reinforcing steel, and the height adjustment is manually leveled by depending on sizing blocks or wooden wedges. Such methods have significant drawbacks: First, positioning accuracy is difficult to secure. Manual measurement is easily affected by environmental interference and operation errors, initial positioning deviation is often more than +/-2 mm, and the initial positioning deviation is far beyond the requirements of the installation standard of a rolling mill (plane deviation is usually less than or equal to +/-0.5 mm and perpendicularity is usually less than or equal to 0.1 °). Second, there is a lack of process dynamic control capability. In the concrete pouring process, the sleeve which is positioned accurately is easy to displace due to vibration, template deformation or foundation early settlement (which can reach 0.5-2 mm), and the traditional tool cannot sense or correct the offset in real time, so that 'early-stage accurate and later-stage misalignment' is caused. And thirdly, the tool is poor in universality and low in efficiency. The sleeves (such as M100, M110, M140 and the like) with different specifications are required to be customized with special brackets and cannot be rapidly switched, the clamps are usually spot welded or bound, and the sleeves are difficult to assemble and disassemble and are easy to damage threads. In addition, the height adjustment depends on experience judgment, a quantization feedback mechanism is not available, micrometer compensation is difficult to achieve, and final installation quality is seriously affected. If the sleeve is out of tolerance, the site is forced to adopt non-standard means such as reaming, forced pulling and the like to repair, so that the connection strength is weakened, and potential safety hazards in the operation of equipment are buried. In recent years, although some projects attempt to introduce laser leveling instrument to assist leveling or simple hydraulic jack to conduct height fine adjustment, the schemes still stay in single-point, static and non-closed-loop stages, and links such as positioning, supporting, fixing, feedback and executing are not integrated into a whole, so that intelligent installation with the whole process, high precision and self adaptation cannot be realized. Therefore, a threaded sleeve mounting technology and a matched device integrating high-precision space monitoring, modularized rapid adaptation, hydraulic self-adaptive support and closed-loop automatic regulation and control are needed, so that the problem that the existing method is insufficient in systematicness in precision control, process stability, construction efficiency, quality reliability and the like is solved, and the severe mounting requirement of a modern large-scale rolling mill on zero tolerance deviation of a foundation embedded part is met.
