Further, several dowel positioning through hole, the dowel positioning through hole setting are additionally provided in the box baseplate
Several tapped blind holes are equipped in the cylinder top surface far from cabinet backboard side, the rotation-limited column, the box roof
Baseplane is equipped with rotation-limited column Blind locating holes, and the rotation-limited column Blind locating holes upper port is equipped with along outer circle and is bolted
Through-hole, the through-hole that is bolted extends to rotation-limited column upper surface and suits setting with the upper port of tapped blind hole, described
The end face that box roof is equipped with several anchor bolt connecting holes is fitted closely with concrete.
The utility model has the beneficial effects that
1, cabinet roof bolting bolt connecting hole ipsilateral end face and concrete fit closely in the utility model, and vehicle is logical
It is out-of-date, mainly by box roof bearing load, effective protection installation place concrete, it is ensured that installation is firm；
2, rotation-limited column bottom is sequentially embedded the first positioning through hole of stainless steel plate and box baseplate in the utility model
With the second positioning through hole, rotation-limited column top is embedded in the Blind locating holes of box roof, can be with after the positioning of rotation-limited column both ends
Stable limit constraint is provided, has and reliable and stable horizontally rotates limit performance.
3, for the utility model mainly using the assembling of nested and bolt connecting mode, process implementing is good, and stability is high.
4, box roof is also used as the top closing plate of entire telescopic device active box in the utility model, daily maintenance or
When maintenance, it is only necessary to which releasing corresponding anchor bolt and connection bolt can easily unload, easy to operate, when being not necessarily to long
Between block traffic.
