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 progress of embedded part and precision are on the impact of follow-up work:
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, embedded part is installed delayed, and basis just cannot have been built; Basis cannot not built completely, and so equipment is in place 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 providing quality goods or brilliant in industry, standard-required is installed without pad equipment, the error of embedded part axis, absolute altitude is ± 2mm within.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 be levelling with pad, bring sizable trouble to electrical construction.The importance of the installing engineering of equipment embedded part in transformer substation construction as can be seen here.
Embedded part is installed as the key procedure of in construction of transformer substation, how to ensure that the degree of accuracy that embedded part is installed and work efficiency become the key of our construction.
At present in practice of construction, adopt a kind of traditional, easy embedded part construction method to control axis and the absolute altitude of embedded part always.It is specifically: first at the axis of the good embedded part position of ground bullet, weld 4-6 at the scene in advance (to gather materials on the spot, reinforcing bar or the leftover bits and pieces of angle steel) simple and easy A-frame, interim supporting leg as embedded part (notices that the height of this support is more lower slightly than the setting height(from bottom) of embedded part, to have the space of adjustment absolute altitude), because support is directly welding, height cannot be regulated, need first to level up support when ground out-of-flatness, and then it is levelling to carry out embedded part, operability extreme difference.
Afterwards through some improvement, the leg of support added height-adjustable screw rod, had which increased 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 deadweight the less tripod that causes rock, cause embedded part steadily to fix, be difficult to location, need repeatedly to adjust, therefore will guarantee that embedded part precision needs the at substantial time.And in adjustment absolute altitude, tripod also can only be coarse adjustment, still shimming or timber wedge carrys out elevation control rearward, accuracy is difficult to control, and work efficiency is not high.
