Abstract

The utility model relates to a pneumatic or hydraulic anchor rod and anchor pile underreamer, which comprises a drill bit 8. The utility model is characterized in that the drill bit is fixed on a lower tray 6 which is fixed on the front end of a force-transferring through hole rod 7; a spring 3 is sheathed on the force-transferring through hole rod; one end of the spring is pushed on the lower tray, and the other end is pushed on an upper tray 1; a spline is sheathed on the tail end of the force-transferring through hole rod; at least one group of combined underreamer knives formed by the hinging of an upper knife 2 and a lower knife 4 are arranged between the upper tray and the lower tray; two ends of the combined underreamer knives are respectively hinged with the upper tray and the lower tray; the external side of the lower knife is provided with drill teeth 5. The utility model can enlarge the diameter in the drilled holes, and the inside diameter is enlarged under the condition that the diameter of the original hole is not changed; the utility model can continuously deepen the holes, and the interior of the holes finally generates a garlic-shaped end body; the garlic-shaped holes are favorable for anchoring pieces and pouring and solidification objects to form an anchor rod and the force bearing area of a surrounding body of an anchor pole is increased, thereby, the purpose of stability can be achieved.

Description

The vapour or the formula anchor pole anchoring pile staving press that surges

Technical field

The reaming machinery that the utility model uses when relating to anchoring pile in geology, the construction works such as the spy of rock mass anchor, slope reinforcement and ground stabilization or bar specifically is a kind of vapour or the formula anchor pole anchoring pile staving press that surges.

Technical background

In the prior art, the required cylindrical hole of anchoring pile or bar in geology, the construction work owing to do not carry out reaming, make bar or stake under strong external force effect because of the unstable ability of losing the job of anchoring.And in the prior art already present staving press actual be that the aperture in columniform hole is strengthened because a mouthful opening directly strengthens, have the unsettled defective of anchoring equally.And to being used for the deep hole of the large-scale bar stake of anchoring, then technology that adopt the blast reaming more, but there is uncontrollability in such technology.

The content of invention

The purpose of this utility model provides and a kind ofly acts on the mechanical hole reaming head by steam-operating or hydraulic power, and its working head can be expanded and shrink, be convenient at the bottom of the hole in moulding head of garlic shape end chamber, and the staving press that can easily from the moulding hole, take out.

For achieving the above object, the technical solution adopted in the utility model is such, and the promptly a kind of vapour or the formula anchor pole anchoring pile staving press that surges comprise drill bit, it is characterized in that: described drill bit is fixed on the lower wall of fixing with power transmission through hole bar front end; Be set with spring on the power transmission through hole bar, one end of spring withstands on the lower wall, the other end withstands on spline package and coils on power transmission through hole bar end, between last dish and lower wall, be equipped with at least one group by fixing a cutting tool and the hinged combined type broad that constitutes of bottom tool, the two ends of described combined type broad are hinged on respectively on the upper and lower dish, and wherein the bottom tool outside has the brill tooth.

The utility model is because the good effect that said structure produces is conspicuous, and promptly it can amplify the diameter that carry out in the hole in the hole of having bored, makes inside diameter expansion under the constant situation of original orifice diameter; Also can make the hole continue to deepen, make the inner head of garlic shape end body that generates in hole at last.The hole of shape helps anchoring piece and waters condensate formation anchor pole like this, has increased the anchor post load area of body on every side, thereby reaches the purpose of stability.

Description of drawings

Above-mentioned purpose of the present utility model can further specify by the non-limiting embodiment that accompanying drawing provides.

The utility model is by following accompanying drawing:

Accompanying drawing 1 is a structural scheme of mechanism of the present utility model;

Accompanying drawing 2 is an accompanying drawing 1A-A sectional view.

Referring to accompanying drawing: among the figure: the last dish of 1-, 2-fix a cutting tool, 3-spring, 4-bottom tool, 5-bore tooth, 6-lower wall, 7-power transmission through hole bar, 8--drill bit.

The specific embodiment

Referring to accompanying drawing, the vapour or the formula anchor pole anchoring pile staving press that surges comprise drill bit 8, and described drill bit is fixed on the lower wall of fixing with power transmission through hole bar 7 front ends 6; Be set with spring 3 on the power transmission through hole bar, one end of spring withstands on the lower wall, the other end withstands on spline package on dish 1 on the power transmission through hole bar end, between last dish and lower wall, be equipped with two groups at a distance of 180 °, by fixing a cutting tool 2 and the bottom tool 4 hinged combined type broads that constitute, the two ends of described combined type broad are hinged on respectively on the upper and lower dish, and wherein the bottom tool outside has the tooth 5 of boring.Described fix a cutting tool 2 and bottom tool 4 have the monocline contact edge in the hinged place, the bottom tool that makes dish gang tool when pressing down is only to extending out.Described combination broad also can be that 3 groups of circumference are equidistantly arranged.

Such during operating principle of the present utility model, be about to staving press and be placed at the bottom of the hole of having held successfully, will go up dish to pressing down, make fixing a cutting tool and the bottom tool expansion of gang tool; Vapour (liquid) power drives goes up dish 1 rotation, drives disc spins down by power transmission through hole bar, also drives the gang tool rotation after expanding simultaneously, thereby produces the cutting hole inwall, reaches the purpose of reaming.

Reaming finishes, last dish unloading, and spring 3 resets, thereby can easily staving press be taken out.

Claims

1, a kind of vapour or the formula anchor pole anchoring pile staving press that surges comprise drill bit (8), it is characterized in that: described drill bit is fixed on the lower wall of fixing with power transmission through hole bar (7) front end (6); Be set with spring (3) on the power transmission through hole bar, one end of spring withstands on the lower wall, the other end withstands on spline package on dish (1) on the power transmission through hole bar end, between last dish and lower wall, at least one group of combined type broad by the hinged formation of (2) and bottom tool (4) of fixing a cutting tool is installed, the two ends of described combined type broad are hinged on respectively on the upper and lower dish, and wherein the bottom tool outside has brill tooth (5).
