Description
Technical field
Lossless leveling method the present invention relates to field of mechanical technique, in specially a kind of jack jacking work.
Background technique
Jack is widely used in the enterprises such as electric power, chemical industry, steel, bridge, machinery, can be used for equipment top lifting, and the disaster relief is rescued
It helps, electric power maintenance, bridge maintaining, weight jacking, static press piling, foundation settlement, Ship Building and Repairing etc. can be also suitably used for finely tuning
Operation, small gap, height space are limited occasion and use.The outstanding advantage of jack is exactly that flexible, light, reliable, economy is high.
No matter which kind of jack, the most basic demand of work is smooth working face.When jacking work in face of such as pipe-line system,
When the object of the surface irregularities such as spherical equipment, often it is forced to replace jacking scheme using other lifting equipments, economy is often not
Such as the former.If being jacked by force using jack, it may be deformed since local stress is excessive by jacking object and even destroy,
It destroys again or because bias causes jack that scuffing of cylinder bore occurs.Take reasonable levelling measure can be to avoid the above problem, sufficiently
Play the good economy of jack.
Existing leveling method still has significant limitation, such as used in Bridge Support Replacement lifting operation quickly
Cement leveling method is only applicable in the opposed flattened rough surface in surface.And the industrial equipment or pipeline for certain cast irons can be with
The method for setting up jacking table top using welding support, there is also following 3 problems for such method: 1. pairs of existing equipments or pipeline produce
Raw irreversible damage；2. the high temperature requirement halt device in welding process uses；3. there are still local stress phenomenon, or top
Discontinuity during rising.Under conditions of not damaging by jacking object, keeps stablizing, uniformly contact, be suitable for simultaneously
Deep camber or the leveling method on extremely irregular surface are urgent problems.In consideration of it, it is proposed that a kind of jack
Jack the lossless leveling method in work.
