Description
Technical field
The present invention relates to the installation field of locating technology of equipment embedded part in a kind of transformer substation construction work progress, specifically a kind of embedded part installation position finder and embedded part installation and locating method.
Background technology
In the construction process of transformer station, the installing engineering of equipment embedded part is an important process, is also one critical process.The impact on follow-up work of the progress of embedded part and precision:
One, the installation progress of embedded part affects the final deadline of equipment Foundations, and equipment installation can be carried out after completing and reaching curing time in basis.That is to say, embedded part is installed and is lagged behind, and basis just cannot have been built; Cannot not build completely on basis, and equipment is in place so also just can only correspondingly postpone backward.
Two, the precision of embedded part construction also plays vital effect to the accuracy of post facility installation in position.According to the standard-required of providing quality goods or brilliant in industry, without pad equipment, install, the error of embedded part axis, absolute altitude is ± 2mm in.If misalignment of axe is excessive, the impression quality that impact is installed; If absolute altitude deviation is excessive, that will have influence on the abutting joint of electric fixtures, need to use pad levelling, to electrical construction, bring sizable trouble.The importance of the installing engineering of equipment embedded part in transformer substation construction as can be seen here.
Embedded part is installed as a key procedure in construction of transformer substation, how to guarantee that the degree of accuracy and work efficiency that embedded part is installed become the key that we construct.
At present in practice of construction, adopt a kind of traditional, axis and absolute altitude that easy embedded part construction method is controlled embedded part always.It is specifically: first at the axis of the good embedded part of ground bullet position, welding at the scene in advance 4-6 (gathers materials on the spot, reinforcing bar or the leftover bits and pieces of angle steel) simple and easy A-frame, as the interim supporting leg (height of noting this support is more lower slightly than the setting height(from bottom) of embedded part, to there is the space of adjusting absolute altitude) of embedded part, because support is directly welding, cannot regulate height, when the out-of-flatness of ground, need to first level up support, and then carry out embedded part levelling, operability extreme difference.
Through some improvement, on the leg of support, add height-adjustable screw rod afterwards, increased like this self levelling function of support.After support leveling, embedded part is placed on support, then carries out leveling.But due to three screw mandrels of stent support and the contact point on ground too little, and the less tripod that causes of deadweight rocks, and causes embedded part steadily to fix, and is difficult to location, need to repeatedly adjust, and therefore will guarantee that embedded part precision need to expend the plenty of time.And adjusting aspect absolute altitude, tripod can only be also coarse adjustment, or by rear shimming or timber wedge carrys out elevation control, accuracy is difficult to control, and work efficiency is not high.
