The present invention is a kind of positioning device of rotary digging stake drill bit, belong to the auxiliary device of rotary digging stake pile foundation construction, it is characterized in that a kind of positioning device of rotary digging stake drill bit includes elastic indicating arm and fixing card, the elasticity indicating arm is compressed spring section, the fixing card includes snap-gauge and screw rod again, the snap-gauge is right angle ∩ shape plate, the elastic indicating arm that a fixed setting level left side is stretched on the left surface of the left facade plate of snap-gauge, threaded hole is opened up on the right facade plate of snap-gauge, screw rod is set in threaded hole, when using this positioning device, three this positioning devices are fixedly mounted to circumference uniform distribution on the upper edge hole of the retaining wall steel bushing of rotary digging stake, by snap-gauge fixing card on the barrel of steel bushing, so that elastic indicating arm is directed to the radial center of steel pile casting and is resisted against on the periphery of drilling rod, when Spiral digging machine is constructed, referring to the deformation of each elastic indicating arm, i.e. The center of stake can be accurately found out, it is easy to use, improve construction quality and efficiency.
Description
Technical field
The invention belongs to the auxiliary devices of rotary digging stake pile foundation construction, more particularly, to a kind of positioning device of rotary digging stake.
Technical background
In recent years, with the raising of the high speed development of national economy and living standards of the people, inhabitation item of the people to oneself
Part has higher requirement, and with being continuously increased for depth of building, requirement of the building to foundation bearing capacity is also increasing,
Various pile foundations, it is also more and more in particular by the pile foundation of rotary digging pile driving construction；The pore-forming of rotary digging stake is by manual operation rotary digging
Machine comes out the soil successively rotary digging of stake position, so some deviations all can be inevitably generated when each rotary digging soil of Spiral digging machine, it is past
Toward causing stake holes deviation, aperture to become larger, construction quality and efficiency are reduced, construction cost is improved.
Summary of the invention
The purpose of the present invention is to propose to a kind of positioning devices of rotary digging stake drill bit, not only make, install simple, user
Just, and the accuracy of stake position can be effectively improved, it is ensured that construction quality saves construction cost.
The object of the present invention is achieved like this: a kind of positioning device of rotary digging stake drill bit (abbreviation positioning device),
Be characterized in: a kind of positioning device of rotary digging stake drill bit includes elastic indicating arm and fixing card, and the elastic indicating arm is pressure
Contracting spring section, the elasticity indicating arm can be 2.5mm × 25mm × 250mm compressed spring system with linear diameter × overall diameter × length
At the fixing card includes snap-gauge and screw rod again, and the snap-gauge is right angle ∩ shape plate, in the left facade plate of the snap-gauge
Left surface on the elastic indicating arm stretched of a fixed setting level left side, open up threaded hole on the right facade plate of the snap-gauge,
Screw rod is set in threaded hole, which can be thumb screw.
Using a kind of this rotary digging stake drill bit positioning device when, first by the retaining wall steel bushing installation of rotary digging stake, embedded in place,
Then three this positioning devices are fixedly mounted to circumference uniform distribution on the upper edge hole of steel bushing, snap-gauge is installed on to the cylinder of steel bushing
It on wall, tightens screw rod and snap-gauge is fixed on steel bushing, and elastic indicating arm is made to be directed to the radial center of steel pile casting, each elasticity
The free end of indicating arm is resisted against on the periphery of drilling rod,, can be accurately referring to each elastic indicating arm when Spiral digging machine is constructed
Find out the center of stake because compressed spring itself have well elasticity and toughness, will not because of in use by
It squeezes and destroys, when the center of the drill bit of Spiral digging machine and drilling rod deviation stake, the elastic indicating arm in this positioning device is (i.e.
Compressed spring) just deformation occurs therewith, suggesting effect intuitively very can be played to mechanical commander, and then commander commands behaviour
Make personnel and ajust the position of drill bit in time to continue to construct.
A kind of positioning device of rotary digging stake drill bit proposed by the invention not only makes, installs simply, easy to use, and
And the accuracy of stake position can be effectively improved, it is ensured that construction quality has saved construction cost.
Make presently in connection with positioning device of the drawings and examples to a kind of rotary digging stake drill bit proposed by the invention further
Explanation.
Detailed description of the invention
Fig. 1 is a kind of schematic front view of the positioning device of rotary digging stake drill bit proposed by the invention.
Fig. 2 is a kind of installation stereoscopic schematic diagram of the positioning device of rotary digging stake drill bit proposed by the invention.
Fig. 3 is stereoscopic schematic diagram when a kind of positioning device of this rotary digging stake drill bit proposed uses.
In Fig. 1, Fig. 2, Fig. 3: 1, elastic indicating arm 2, fixing card 3, steel bushing 4, drilling rod
Specific embodiment
It can be seen that a kind of positioning device of rotary digging stake drill bit (abbreviation positioning device), feature from Fig. 1, Fig. 2, Fig. 3
Be: a kind of positioning device of rotary digging stake drill bit includes elastic indicating arm 1 and fixing card 2, and the elastic indicating arm 1 is compression
Spring section, the elasticity indicating arm 1 can be 2.5mm × 25mm × 250mm compressed spring system with linear diameter × overall diameter × length
At the fixing card 2 includes again snap-gauge and screw rod, and the snap-gauge is right angle ∩ shape plate, in the left facade of the snap-gauge
The elastic indicating arm 1 that a fixed setting level left side is stretched on the left surface of plate opens up threaded hole on the right facade plate of the snap-gauge,
Screw rod is set in threaded hole, which can be thumb screw.
Using a kind of this rotary digging stake drill bit positioning device when, first by the installation of retaining wall steel bushing 3 of rotary digging stake, it is embedded just
Position, three this positioning devices are then fixedly mounted to circumference uniform distribution on the upper edge hole of steel bushing 3, snap-gauge is installed on steel bushing
It on 3 barrel, tightens screw rod and snap-gauge is fixed on steel bushing 3, and be directed to elastic indicating arm 1 in the radial direction of steel pile casting 3
The free end of the heart, each elasticity indicating arm 1 is resisted against on the periphery of drilling rod 4, when Spiral digging machine is constructed, referring to each elastic indicating arm
1, can accurately find out the center of stake because compressed spring itself have well elasticity and toughness, will not because of
It is extruded and destroys in use process, when the center of the drill bit of Spiral digging machine and the deviation stake of drilling rod 4, in this positioning device
Just deformation occurs therewith for elastic indicating arm 1 (i.e. compressed spring), intuitively can play suggesting effect to mechanical commander very, into
And the position that commander commands operator to ajust drill bit in time continues to construct.
