Positioning construction of tower mechanical equipment chassis and preparation method thereof

Abstract

The invention relates to a positioning construction of the tower mechanical equipment chassis and a preparation method thereof, and the positioning construction is suitable for the vertical orientation and connection of the cross-beam of chassis and concrete foundation beam of the tower mechanical equipment. The positioning construction ensures that the foundation bolt position is not limited by the concrete along the lateral and longitudinal directions of the concrete foundation beam and the diameter and length of the foundation bolt can be changed according to specific requirements so that the widely used vertical orientation between the standardized and serialized prefabricated concrete foundation and the tower mechanical equipment using different chassis cross-beams as the support canbe realized while the section of the concrete foundation beam is not weakened and the strength and integrity of the foundation are guaranteed, the materials and manpower can be saved further, the processes are reduced, the construction period is shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the vertical positioning structure of the foundation beam and the upper mechanical equipment of the concrete foundation of the mast-type mechanical equipment used periodically or fixedly. Background technique [0002] At present, construction, electric power, petroleum, information, mining, and military fields are periodically mobile, such as construction fixed tower cranes, wind power generators, oil extraction machines, signal towers, drilling machines, and large land-based radars. Structural foundations mostly use integral cast-in-place concrete foundations. The obvious disadvantages are that the utilization rate of resources is extremely low, the construction period is long, the production period is longer in cold regions, the construction is difficult in arid regions, and it cannot be reused. At the same time, it causes a lot of waste of resources and environmental pollution. . In recent years, the cross-shaped combined t...

Problems solved by technology

However, for the two technical and economic goals of repeated use and light weight of the combined foundation of tower-mast mechanical equipment, there are wastes and narrow adaptability caused by the fixed combination form caused by the design of the basic structure being restricted by the cross beam of the upper mechanical equipment chassis; prior art For mechanical equipment with small overturning moments and vertical forces, especially fixed construction tower cranes with fixed underframe cross beams, it is urgent to technically solve the problem of underframe cross beams of tower cranes of the same type produced by various domestic manufacturers. Different structural dimensions lead to different vertical connection structures with the foundation. The vertical connection structure of a type of combined foundation cannot be fixedly connected with the underframe cross beams of tower cranes of the same type from several manufacturers, that is, the universality of the foundation.

Although the existing non-one-off anchor bolt vertical positioning connection structure solves the problems of anchor bolt displacement and diameter and length transformation, it also eliminates the damage to the section of the concrete foundation beam and overcomes the foundation structure. A hidden danger of safety; but there are still defects such as complex structure, large amount of materials, cumbersome process, and uneconomical; the industrialization practice of the combined foundation has proved that this is the impact that must be broken through to speed up the industrialization of the tower-mast mechanical equipment combination foundation technical bottlenecks
