Vertical positioning structure of chassis rood beam of tower mast type mechanical equipment

Abstract

The invention relates to a vertical positioning structure of a chassis rood beam of tower mast type mechanical equipment, which is applicable to vertical positioning connection of the chassis rood beam of tower mast type mechanical equipment and a foundation concrete beam, leads the position of an anchor bolt not to be limited by the concrete horizontally and longitudinally along the concrete foundation beam and leads the diameter and length of the anchor bolt to be capable of being replaced and changed according to the specific requirements, thus realizing vertical positioning with wide applicability between standard and series prefabricated concrete foundation and the tower mast type mechanical equipment adopting chassis rood beams with different structures as support under the conditionthat the section of concrete foundation beam is not weakened and the foundation strength and integrity are guaranteed.

Description

Technical field [0001] The invention relates to a vertical positioning structure of a tower-mast type mechanical equipment concrete foundation that is periodically moved or fixed. Background technique [0002] At present, the periodic mobile use of construction, electricity, petroleum, information, geology and mining, and military fields, such as building fixed tower cranes, wind turbines, oil extraction machines, signal towers, drilling rigs and large land-based radars, etc. Most of the structural foundations use integral cast-in-place concrete foundations. The obvious disadvantages are extremely low resource utilization, long construction period, longer production period in cold areas, difficult construction in arid areas, and can’t be reused, causing a lot of waste of resources and environmental pollution. . In recent years, a cross-shaped modular tower crane foundation with prefabricated concrete components has come out, opening up the direction and path of modular, reusab...

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 some existing non-one-time fixed anchor bolt vertical positioning connection structures solve the problems of anchor bolt displacement and diameter and length transformation, they all cause damage to the cross-section of the concrete foundation beam to varying degrees and become a foundation structure. A hidden danger of safety; or the structure is complex, the amount of materials used is large, and it is uneconomical; the industrialization practice of the combined foundation has proved that this is a technical bottleneck that must be broken through and affects the accelerated realization of the industrialization of the tower-mast mechanical equipment combination foundation
