Summary of the invention
The object of the invention is to provide a kind of simple to operate, the Steel Bridge U-shaped rib that operating efficiency and quality can be made to be significantly improved overall cover type turnover drilling system to overcome above-mentioned shortcoming of the prior art.
For achieving the above object, the present invention adopts above technical scheme:
A kind of Steel Bridge U-shaped rib overall cover type turnover drilling system, comprises rotation positioning device and overall cover type model; Described rotation positioning device comprise a U-shaped rib inner support and with the lower seat of described U-shaped rib inner support by pinned connection, described lower seat is located on a seat board, described seat board is relatively set with two horizontal location baffle plates in position, the described lower seat left and right sides, described seat board is provided with one to connect described U-shaped rib inner support vertical location-plate by vertical alignment pin in the front side of described lower seat; Described overall cover type model comprises one for U-shaped rib locator card being fixed in the П type component in U-shaped rib inner support, and described П type component is provided with multiple boring location borehole jack.
Described П type component be provided with for locate to wire casing.
Described boring location borehole jack is embedded on described П type component.
Described П type component is processed by steel plate.
The present invention carries out boring location owing to have employed overall cover type model, and U-shaped rib bolt hole group relative accuracy is significantly improved, practical, solve the deficiency of current U-shaped rib boring, except holing for U-shaped rib, also can be applicable to the boring of U-shaped like rib structure, applicability is strong.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is further elaborated.
See Fig. 3 ~ 4, a kind of Steel Bridge U-shaped rib overall cover type turnover drilling system, comprises rotation positioning device and overall cover type model; Described rotation positioning device comprises the horizontal location baffle plate 3-7 of U-shaped rib inner support 3-1, vertical alignment pin 3-2, support rotating bearing pin 3-3, lower seat 3-4, seat board 3-5, vertical location-plate 3-6, two relative positions; Described lower seat 3-4, vertical location-plate 3-6, horizontal location baffle plate 3-7 are fixed on seat board 3-5; Described U-shaped rib inner support 3-1 is connected with lower seat 3-4 by rotating pin 3-3, and described vertical location-plate 3-6 is connected with described U-shaped rib inner support 3-1 by vertical alignment pin 3-2; Described overall cover type model comprises one for U-shaped rib 1 locator card being fixed in the П type component 2-1 on U-shaped rib inner support 3-1 and being located at the boring location borehole jack 2-2 on described П type component 2-1.
Further, described П type component 2-1 be provided with for locate to wire casing.
Further, described boring location borehole jack 2-2 is embedded on described П type component 2-1.
Further, described П type component 2-1 is processed by steel plate.
During drilling operation, be positioned over by U-shaped rib 1 on U-shaped rib inner support 3-1, П type component 2-1 is positioned over also by carrying out line wire casing on U-shaped rib 1, then fixes П type component 2-1, U-shaped rib inner support 3-1 and U-shaped rib 1.During vertical location drilling, vertical alignment pin 3-2 is inserted in the dowel hole of lower seat 3-4 and vertical location-plate 3-6; During horizontal drilling, П type component 2-1, U-shaped rib inner support 3-1, U-shaped rib overturn together, and П type component 2-1 drops on a horizontal location baffle plate 3-7.
