Described flexible drive axle is the multistrand rope with certain rigidity.
Described buncher is reversion variable-speed motor, rotating speed 0-300 revolutions per second.
Described damping supporting positive cover is heavy wall plastic cement pipe nipple, and the diameter of damping supporting positive cover is identical with the diameter of drill bit.
A damping supporting positive cover is at least installed at described bit sub place, and in order to control drilling direction, while preventing from pressurizeing, Flexible Transmission bending shaft bores and hinders tube wall.
The coefficient of elasticity of described two ftercompction springs is determined by bit size and buncher power.
The beneficial effects of the utility model are: by flexible drive axle, power is passed to drill bit, at the ad-hoc location fixed series damping supporting positive cover control drill bit direct of travel of flexible drive axle and bit sub, prevent from damaging " U " shape pipe, ftercompction spring pulls motor drilling follow on rail bracket to enter, automatic compensation, realizes drill bit creeping into continuously in " U " shape pipe.
Accompanying drawing explanation
The raw DS300 type of Fig. 1 prior art Ai Mo densometer structural representation.
Fig. 2 is the utility model drills through device schematic diagram for cementing concrete truck " U " shape tube densimeter.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 2, the device that drills through for Cementing cementing truck " U " shape tube densimeter of the present utility model, comprise buncher 1, flexible drive axle 8 and drill bit 6, buncher 1 passes through axle sleeve empty boasting on two doorframes of the motor rail bracket 2 of one " door " font, on two doorframes of the motor rail bracket 2 of " door " font, a ftercompction spring 3 is set respectively, pull buncher 1 to realize with boring ftercompction in 2 follow-ups of motor rail bracket, be provided with the stationary fixture 9 of fixing " U " shape pipe at the opening two ends of the motor rail bracket 2 of " door " font, flexible drive axle 8 one end joints are bearing pin joint 4, in insertion motor shaft sleeve, other end joint is the bit adapter 5 with rectangular receptacle, the bit sub 10 of drill bit 6 inserts and is fixed in the socket of bit adapter 5 of rectangle, on flexible drive axle 8, fix several damping supporting positive covers 7.
Described flexible drive axle 8 is for having the multistrand rope of certain rigidity.
Described buncher 1 is reversion variable-speed motor, rotating speed 0-300 revolutions per second.
Described damping supporting positive cover 7 is heavy wall plastic cement pipe nipple, and the diameter of damping supporting positive cover 7 is identical with the diameter of drill bit 6.
A damping supporting positive cover 12 is at least installed at described bit sub 10 places, and in order to control drilling direction, while preventing from pressurizeing, bending the boring of flexible drive axle 8 hindered tube wall.
The coefficient of elasticity of described two ftercompction springs 3 is determined by bit size and buncher power.
Specifically, buncher is by axle sleeve empty boasting on motor rail bracket, and two ftercompction springs pull motor to follow up at rail bracket, realizes with boring ftercompction; Flexible drive axle two ends are fixed with special joint, one end joint is bearing pin, insert in motor shaft sleeve and locate anticreep with pin rod, axle sleeve is connected with motor shaft by keyway, other end joint is rectangle drill socket, when bit sub (rectangle) inserts after rectangle drill bit interface, be screwed into set bolt in the groove of bit sub and locate, while preventing flexible drive axle to pull out, drill bit comes off; On flexible shaft and bit sub, optionally fix several damping supporting positive covers, while guaranteeing that ftercompction spring is exerted pressure automatically, flexible drive axle is not bending, drill bit can obtain and creep into the pressure needing, damping supporting positive cover position depends on the needs, at Pipeline Curvature larger part, damping supporting positive cover spacing is shorter, otherwise can be larger, on bit sub, at least fix a damping supporting positive cover, prevent from damaging tube wall.Power is passed to drill bit by flexible drive axle, drives drill bit to rotate, and forms automatic drilling system together with automatic compensation follow-up device, drill bit continuous crushing Behavior of Hardened Cement Paste, and passage forms continuously.
Power is a reversion variable-speed motor, rotating speed 0-300r/s, and motor can slide along track on motor rack.Adaptation " U " shape is managed 11 interior different parts and is crept into needs, adopts higher drilling speed at straight section position, and curvature is used less rotating speed compared with large part, prevents from damaging tube wall.Use reverse motors to prevent that flexible drive axle forward is loose,
Flexible drive axle is one to have the multistrand rope of certain rigidity, and one end joint is bearing pin, inserts in the axle sleeve being connected with motor key, penetrates anti-rotation with pin rod; Other end joint is drill socket, when rectangle bit sub inserts after drill socket, is screwed into drill bit while preventing flexible drive axle pull-out in bit sub groove comes off with screw.Two joints are convenient and fast connection, and driving torque is large, stall proof.
Damping supporting positive cover is heavy wall plastic cement pipe nipple, and diameter is identical with bit diameter, uses Special clip along flexible drive axle axial restraint.A damping centralizer is at least installed at bit sub place, and in order to control drilling direction, while preventing from pressurizeing, Flexible Transmission bending shaft bores and hinders tube wall.
Bit diameter is less than 25mm, and bit sub can be different in size depending on bored position, and straight section adopts long handle drill bit, protects directly anti-obliquely, and bending section minimizing bit sub length, is convenient to change direction.The water booster system that drilling follow enters is two identical springs, and coefficient of elasticity is mainly depending on bit size and power of motor.
In sum, content of the present utility model is not limited in the above-described embodiment, knowledgeable people in same area can propose easily other embodiment within technological guidance's thought of the present utility model, but within this embodiment is included in scope of the present utility model.
