Abstract
The invention discloses a pouring square pile drill bit which comprises a downhole engine, a driven wheel and a caterpillar track. The downhole engine is connected with a drill rod. The downhole engine and the driven wheel are connected through a driving gear and a driven gear, and the driven wheel is engaged with the caterpillar track through the driven gear. According to the technical scheme, a pouring square pile can be formed at a time under a slurry breast wall, and the pouring square pile drill bit is simple in structure, convenient to mount and suitable for pouring square piles with different cross sections in soft soil areas.
Description
Technical field
The present invention relates to construction with stake machine field and in particular to a kind of perfusion square pile drill bit.
Background technology
Cast-in-situ bored pile is widely used in foundation pit system, is usually used in cantilever pile supporting system, campshed+inner support support system, pile-anchor supporting system etc., and generally circle stake.In theory, under same cross-sectional, the anti-bending strength of square pile is better than circle stake.As using drill-pouring square pile, as fender post, the foundation ditch protective capacities for soft clay area will strengthen.
Content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of structure is simple, easy for installation, be applied to the perfusion square pile drill bit of soft clay area.
For achieving the above object, the technical scheme is that a kind of perfusion square pile drill bit, including the down-the-hole engine being connected with drilling rod and driven pulley and crawler belt composition, described down-the-hole engine is connected by driving gear and driven gear with driven pulley, and described driven pulley is engaged with crawler belt by driven gear.
By adopting technique scheme, down-the-hole engine is located at drill bit internal, it is connected with driven pulley, crawler belt by gear, guarantee to form square stake holes, and adopt mud off, and space turnover between crawler belt and gear for the mud, simple to operate, one-shot forming, and it is adapted to the perfusion square pile of different cross section by adjusting component diameter.
The present invention is further arranged to: described drilling rod maintains static, and has stay to be connected between driven pulley.By this setting, thus fixing driven pulley.
The present invention is further arranged to: described crawler belt wraps up 4 driven pulleys and is square, described crawler sections hollow.By this setting it is ensured that crawler belt and driven pulley are closely coupled.
The present invention is further arranged to: described driven gear is in vertical concave-convex surface.By this setting, driven pulley and crawler belt setting are more reasonable.
The present invention is further arranged to: described down-the-hole engine and crawler belt bottom surface are all placed with cutter head.By this setting, the cutting power to the soil body for the drill bit can be strengthened.
The invention has the advantage that present configuration setting is rationally, driven pulley and crawler belt rotary drilling are driven by drivewheel, square stake holes can be formed, engine is located at drill bit internal, decreases the kinetic energy loss that drilling rod power transmission leads to, lower section sets cutter head, it is more suitable for soil cutting, structure is simple, easy for installation, one-shot forming.
With reference to specification drawings and specific embodiments, the invention will be further described.
Brief description
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the a-a sectional drawing of the embodiment of the present invention.
Fig. 3 is the b-b sectional drawing of the embodiment of the present invention.
Specific embodiment
As shown in Figure 1 to Figure 3, a kind of perfusion square pile drill bit disclosed by the invention, wrap the down-the-hole engine 1 being connected with drilling rod 2 and driven pulley 3 and crawler belt 4 forms, it is characterized in that: described down-the-hole engine 1 passes through driving gear 5 with driven pulley 3 and driven gear 6 is connected, and described driven pulley 3 is engaged with crawler belt 4 by driven gear 6.The square pile of different cross section can be adapted to by adjusting component diameter.
As preferred, described drilling rod 2 maintains static, and has stay 7 to be connected between driven pulley 3.
For making this crawler belt 4 fixation relatively reliable, as preferred, the crawler belt 4 described in the present embodiment wraps up 4 driven pulleys 3 and is square, described crawler belt 4 part hollow, and described driven gear 6 is in vertical concave-convex surface.
Described down-the-hole engine 1 and crawler belt 4 bottom surface are all placed with cutter head, and this technical scheme can strengthen the cutting power to the soil body for the drill bit.
During practical application, down-the-hole engine 1 is located at below drilling rod 2, does not pass through drilling rod 2 and directly drives driven pulley 3 and crawler belt 4 to rotate, drilling rod 2 does not rotate.The down-the-hole engine 1 down-cutting soil body, crawler belt 4 cuts the soil body and forms square stake holes, using mud off.Structure is simple, easy for installation, stake holes one-shot forming.
The specific descriptions to the present invention for the above-described embodiment; it is served only for the present invention is further described; it is not intended that limiting the scope of the present invention, the technician of this area, according to the content of foregoing invention, the present invention is made with some nonessential improvement and adjustment each falls within protection scope of the present invention.
