New type base for mast type mechanical equipment

Abstract

A new type of foundation for flagpole mechanical device consists of three kinds of level prestress connection system as top and bottom single hole, top single and bottom double hole as well as middle and bottom single hole; concrete shearing-proof and displacement-proof structure, integrated positioning structure, the same tilting torque for one set of foundation, vertical connection structure being set on bottom frame cross beam on top mechanical device and being set in different structure size as per requirement of vertical force.

Description

technical field [0001] The invention relates to a concrete prefabricated component used in periodic movement or a mast-type mechanical equipment foundation combined with other solid bulk materials with a certain bulk density. Background technique [0002] At present, construction, electric power, petroleum, information, mining, and military fields are used periodically, such as construction fixed tower cranes, wind power generators, oil extraction machines, signal towers, drilling machines, large radar and other mast-type mechanical equipment foundations Most of them use the integral cast-in-place concrete foundation. The obvious disadvantages are that the resource utilization rate is extremely low, the construction period is long, and the production period is longer in cold regions, so 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 tower crane foundation of concrete prefab...

Problems solved by technology

There are wastes and narrow adaptability caused by the fixed combination form due to the restriction of the basic structure design by the cross beam of the undercarriage of the mechanical equipment; the existing technology is suitable for mechanical equipment with small overturning moment and vertical force, especially the construction tower cranes in my country. Fixed construction tower cranes with fixed underframe cross beams with a stock of more than 80% urgently need to technically solve the structure of the vertical connection with the foundation caused by the different structural dimensions of the underframe cross beams of the same type of tower cranes produced by various domestic manufacturers The vertical connection structure of a type of combined foundation formed differently cannot be fixedly connected with the underframe cross beams of tower cranes of the same type from several manufacturers, that is, the universality and wide applicability of the foundation, the industrialization of the combined foundation Practice has proved that this is a bottleneck problem that must be broken through to speed up the industrialization of mast-type machinery and equipment.
