Background technology
Screw sand washer is power source with the motor; After decelerator slows down, drive helical axis and at the uniform velocity rotate, helical axis drives the silt particle and the current that get into the casing rear portion and stirs, and cleans impurity and mud layer; Let roughing sand begin progressively to decompose; Isolated impurity mud layer is discharged through adjutage under the effect of current, and washed ore is transported to discharge gate and discharges under helical blade rotates, thereby reaches the washed-out sand purpose.Helical blade draws after with the circular steel plate continuous welding of many groups and forms.The rounded thin plate of single helical blade, and be uniformly distributed with the bolt hole that many groups are connected with wear plate on the complete cycle.In order to improve drilling efficiency, the general mode that adopts many group helical blades to hole simultaneously.
In practical operation, also lack a kind of anchor clamps that are exclusively used in this helical blade boring.
Summary of the invention
The utility model discloses a kind of screw sand washer helical blade boring grab according to the deficiency of prior art.The problem that the utility model will solve provides a kind ofly can conveniently carry out the anchor clamps that many group helical blades are processed simultaneously according to screw sand washer helical blade characteristics, to improve working (machining) efficiency.
The utility model is realized through following technical scheme:
Screw sand washer helical blade boring grab comprises bracing frame, locating ring and clamping frame, it is characterized in that: the support frame as described above center has screw rod to be connected through bolt combination with clamping frame, between bracing frame and clamping frame, locating ring is arranged.
Said locating ring is annular, evenly is provided with 4 rectangular indentation of symmetry on the annulus, is provided with 4 arc boss in the middle of annulus cylindrical two breach.
Support frame as described above and clamping frame are cross, and clamping frame is arranged in the locating ring rectangular indentation when bracing frame and clamping frame combination.
Said clamping frame cross end symmetrical is provided with hanger.
Above-mentioned bracing frame can weld standing screw again by after the vertical welding of two channel-section steels in the junction; Locating ring is annular, evenly is provided with 4 rectangular indentation of symmetry on the annulus, is provided with 4 arc boss between annulus cylindrical two breach, and rectangular indentation is used for fixing clamping frame, arc boss and helical blade centre bore matching and fixing helical blade; Adding man-hour, helical blade is placed bore template in the above after placing, and bore template designs according to the helical blade size, is drilled with the bolt hole identical with helical blade on it; Clamping frame can be by welding with another channel-section steel is vertical after the two channel-section steel open butt welds, and the junction is provided with the through hole that allows fixing screw mandrel to pass through.Two channel-section steel diagonal angle ends of open butt weld are welded with hanger, are used for the lifting of single unit system.
In sum; The utility model helpfulness: the utility model adopts bolted that helical blade boring working (machining) efficiency is improved through bracing frame, locating ring and clamping frame; Through the locating ring rectangular indentation accurately be fixed and clamped frame, arc boss accurately fixedly helical blade machining accuracy is improved, hanger being set convenient is liftings of single unit system in a large amount of processing.
