Description

High capacity motor leveling tool

Technical field

It the utility model is related to a kind of specific purpose tool, more particularly to a kind of high capacity motor leveling tool.

Background technology

Thermal power generation is that accounting highest is a kind of in China's supply of electric power；For thermal power generation unit, unit generating work( Rate is bigger, to fire coal utilization rate it is higher, pollution it is smaller, therefore, 600MW and 1000MW thermal power generation groups have substituted 300MW machines Group, turn into the first-selected type of the construction project of China's thermal power generation at present and in the future；And at least ten in each fired power generating unit Large-scale drive device, rotated by these large-scale drive device band movable vane pieces, the whole circulatory system is circulated；These are large-scale It is the motor of large fan after the drive device of drive device including the large-scale coal pulverizer in stokehold, stove, various big in main building Drive device of the type pump housing etc., these large-scale drive devices are driven by high capacity motor, and these high capacity motors are pacified Coaxiality error is required during dress within 5, because weight of equipment is big, precision prescribed is high, horizontal adjustment work when mounted Make that difficulty of construction is big, complex operation, make slow progress, therefore installation effectiveness is very low always.

Mainly there is following several the method for horizontal adjustment during existing high capacity motor installation：

First, hydraulic jack method of adjustment：The method was once the side of high capacity motor centering horizontal adjustment most usually One of method, but it there is also some shortcomings：1. due to high capacity motor bottom foundation construction error control range compared with Greatly, therefore when motor is installed often occur that the distance on motor bottom to basis is less than the minimum height of hydraulic jack Degree, makes hydraulic jack lack scope for their abilities；2. hydraulic jack is expensive for common screw jack, And hydraulic oil pipe joint is easily damaged, often occur in use pressure release or can not pressure release a kind of state, cause Construction progress is slow.

2nd, bolt adjusting method：Bolt adjusting method is used in equipment center line leveling and adjusting technology mostly, in equipment water Also it is widely used during Heibei provincial opera is whole, the application in equipment level adjustment is generally divided into two kinds of external and bottom type：(1) outside The formula of putting is that nut is welded on into equipment base, then can carry out the adjustment of equipment height by rotating screw rod, and its shortcoming is：1. need To be welded and fixed with equipment, cause different degrees of wound in itself to equipment；2. nut wall thickness is thin, it is impossible to is largely welded Connect, otherwise easily welding deformation occur and cause screw rod can not have rotation by oneself, lose meaning；Limited 3. the welding capacity of nut is small The supporting power of pad；(2) bottom type is commonly called as " small old man ", and bolt and nut are placed directly in the device bottom that need to be adjusted, and leads to Rotating screw cap is crossed to realize the horizontal adjustment of equipment, its shortcoming is：1. the direct contact arrangement of rotary part or basis, in adjustment The amount of moving horizontally of equipment is larger；2. spanner directly exerts a force to bolt, larger power is needed in the larger equipment of adjustment weight Amount exerts a force to realize, or using press rods are lengthened to increase torque, reduce, handling poor.

In summary, adjusted at present in high capacity motor horizontal adjustment field still without a set of fully effective method to realize The integrality of rectification journey, whole construction process can only be completed by the technology complementation of various methods.
