Abstract
Disclosed is a crankshaft drill needle for a channel making machine. The crankshaft drill needle comprises a submersible motor, a crankshaft, a connection disk, and a drill needle. The crankshaft is connected at the lower end of the submersible motor; the crankshaft is connected with the drill needle by the connection disk; the lower end of the crankshaft is fixed on a supporting frame through a shaft sleeve. The submersible motor of the utility model drives the crankshaft, and then the crankshaft drives the drill needle to rotate so as to drill into hard soil layer. The utility model provides the drill needle especially for the channel making machine applied to underground seepage prevention walls.
Description
One, technical field
The present invention relates to a kind of The trench saw drill point, particularly a kind of underground impervious wall The trench saw bent axle drill point.
Two, background technology
The The trench saw operating principle is: submersible motor drives bent axle and rotates, and bent axle is through connecting rod, and two saw cuttves synchronously, moved back and forth the cuts formation grooving in opposite directions about rocking arm promoted.
The trench saw is in the grooving process, and two saw cutter such as discontinuity can cause The trench saw vibration or skew, and should add the location drill point this moment in the The trench saw middle and lower part, makes the drill point location of at first burying, and prevents that The trench saw from shaking or deflection.
At present, the The trench saw drill point is and does not rotate, if meet hard soil layer, drill point is difficult to maybe can't tunnel owing to not rotating.
Three, summary of the invention
The present invention is the deficiency that remedies prior art, and a kind of The trench saw bent axle drill point is provided, and the present invention drives bent axle by submersible motor, and the crank-driven drill point rotates, and easily creeps into hardpan.
The present invention realizes through following technical scheme:
A kind of The trench saw bent axle drill point comprises submersible motor, bent axle, terminal pad, drill point; The submersible motor lower end is connected with bent axle, and bent axle links to each other with drill point through terminal pad, and said bent axle (4) is driven by submersible motor (3), and the bent axle lower end is fixed on the bracing frame through axle sleeve.
The present invention is because hardpan can be easily crept in the rotation of drill point.
Four, description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Accompanying drawing is The trench saw and structural representation of the present invention
Among the figure: 1. lifting tackle, 2. pulp steel pipe, 3. submersible motor, 4 bent axles, 5. axle sleeve, 6. terminal pad, 7. drill point, 8. saw cutter, 9. water spout, 10. saw tool arm, 11. bracing frames.
Five, the specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment comprises submersible motor 3, bent axle 4, terminal pad 6, drill point 7; Submersible motor 3 lower ends are connected with bent axle 4, and bent axle links to each other with drill point 7 through terminal pad 6, and the bent axle lower end is fixed on the bracing frame 11 through axle sleeve.
Diving drill point 3 drove bent axles 4 when the present invention worked, and bent axle 4 drives drill points 7 through terminal pad 6 and rotates, and drill point bores moving stratum pore-forming in rotation process, and drill point is the hand-hole location at first, make two groups saw cuttves in the grooving process balance, do not shake.
The present invention is the special-purpose drill point of underground impervious wall The trench saw.
Claims (1)
