Abstract
The utility model belongs to the technical field of a mechanical device of a long spiral drilling machine in civil engineering foundation treatment, and particularly relates to a drilling rod position limiting system of a long spiral drilling machine. The long spiral drilling machine solves the problems that a drilling rod of the long spiral drilling machine is easy to bend, so the bore diameter is enlarged, and the concrete waste is serious. The drilling rod position limiting system of the long spiral drilling machine comprises a movable protection tube, wherein the movable protection tube comprises a protection tube part and a connecting part, the protection tube part is sheathed on a drilling rod, one end of the connecting part is connected with the protection tube part, the other end of the connecting part is movably arranged on a chute of an upright post of a drilling machine support, the upper side of the connecting part is fixedly provided with a fixed pulley, a steel stranded wire is arranged on the fixed pulley in a penetrating way, one end of the steel stranded wire is fixedly arranged on a drilling machine power head hung with the drilling rod, and the other end of the steel stranded wire is connected with a windlass through a plurality of pulleys. The drilling rod position limiting system has the advantages that the movable protection tube is additionally arranged on the drilling rod, the stressed bending deformation of the drilling rod is effectively controlled, the counterbore diameter is reduced, and the consumption of the concrete is reduced.
Description
Technical field
The utility model belongs to the technical field of long-spiral drilling machine mechanical device in civil engineering groundwork processing, specifically a kind of long screw auger driver drilling rod caging system.
Background technology
During ground is processed, castinplace pile is a kind of the type of commonly using, and includes the pile foundations such as CFG stake, plain concrete pile, and pore-forming mode generally adopts long-spiral drilling machine to creep into, pumping of concrete.In drilling process, run into compared with hard formation, long screw auger driver drilling rod easily bends, and causes borehole enlargement, and concrete waste is serious.
Therefore, need to adopt a kind of stopping means, the lateral deformation of restriction drilling rod, keyhole aperture, removable casing arises at the historic moment, and removable casing can decline and decline along with drilling rod, guaranteed that casing, all the time in the centre of drilling rod, has limited to greatest extent drilling rod and bended.
Summary of the invention
The utility model easily bends in order to solve long screw auger driver drilling rod, causes borehole enlargement, concrete to waste serious problem, and a kind of long screw auger driver drilling rod caging system is provided.
The utility model is taked following technical scheme: long screw auger driver drilling rod caging system, comprise mobile casing, mobile casing comprises casing part and coupling part, casing is partly enclosed within on drilling rod, one end, coupling part connects on the chute that casing part, other end packaged type be installed in the column that rig supports, coupling part upside is fixed with fixed pulley, on fixed pulley, be equipped with steel strand, steel strand one end is fixed on the drill power head that hangs drilling rod, and the other end is connected with hoist engine by some pulleys.
The utility model operation concrete steps are as follows:
1. removable casing is used movable pulley to be suspended in the middle of drilling rod, and one end connects hoist engine, and the other end is connected with drilling machine platform by the fixed pulley of rig support, top.
2. removable casing makes it support and to move up and down along rig by chute.
3. install after removable casing, lower brill, can see that it is half of unit head displacement that removable casing moves down distance, and removable casing can remain at 1/2nd places of the above drilling rod in ground, limit to greatest extent drilling rod distortion, saved concrete.
Compared with prior art, the utility model, by add removable casing on drilling rod, has effectively been controlled the bend by pressure distortion of drilling rod, has reduced reaming aperture, has saved concrete; By running block and fixed pulley group, casing is arranged on drilling rod, has realized the mobile and harmonious movement of casing with drilling rod.
