Description
Technical field
The present invention relates to a kind of Soft Ground equipment of construction machinery, particularly relate to a machine stirring device.
Background technology
Bi-directional cement soil mixing pile machine at present in Soft Ground construction works field, bidirectional rotation drill bit three parts that the inside and outside drilling rod comprise headstock, being connected with headstock connects, headstock is placed in the stake machine frame of drilling rod upper end, inside and outside drilling rod bidirectional rotation operation work.The bidirectional rotation of inside and outside drilling rod is that dependence two motors and two cover transmission systems drive respectively, that is a motor and transmission system are responsible for driving interior drilling rod direction to rotate, and another motor and transmission system are responsible for driving another direction of outer drilling rod to rotate.Obviously, this equipment is that use two motors and two cover transmission systems drive inside and outside drilling rod rotating operation, complex structure respectively, bulky, power consumption, and can only single construction infection construction speed.
In order to solve the deficiencies in the prior art, China Patent Publication No. is that CN201459712 discloses a kind of single-power bidirectional soil-cement mixing pile mixing device, comprise power transmission gear mechanism, interior drilling rod and outer drilling rod, it is characterized in that, this power transmission gear mechanism is single-power drive gear mechanism, the power output part of power transmission gear mechanism is connected with interior drilling rod, and interior drilling rod and outer drilling rod are connected by drive gear mechanism.This technical scheme can realize by single power to realize inside and outside drilling rod bidirectional rotation, but in its drive gear mechanism utilizes, drilling rod arranges spiral gear drive mechanism, outer drilling rod is driven to reversely rotate, but its transmission system due to rod rotation speed inside and outside it identical, interior drilling pipe cannot be formed slowly run, outer drilling pipe height cuts, and when carrying out practice of construction operation, efficiency has much room for improvement.
Moreover the concentric double-shaft stake machine field of prior art, the top that spray head is all arranged on gear-box utilizes interior pipe whitewashing, bleeding under the effect of the pressure in the spray head course of work, causes entering due to slurry in inner and outer pipes crack, causes inner and outer pipes plugging or the existing picture of locking.Due to spray head long-term between work and produce wearing and tearing and to overflow slurry, once excessive slurry will infiltrate inside gear housing, cause the travelling gear inside casing and bearing damage, have much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of single power and control inside and outside drilling pipe bidirectional rotation, and it is different to realize inside and outside drilling pipe rotating speed, improve stirring and mixing effect, prevent bleeding from causing the concentric double-shaft in inner and outer pipes plugging locking, extension device application life under to whitewash stake machine stirring device.
The present invention is for solving the problems of the technologies described above, provide following technical scheme: a kind for the treatment of of soft foundation mixing plant, comprise headstock, the inside and outside power transmission shaft of coaxial socket mutually, drilling pipe and be arranged at the drill bit of interior drilling pipe end inside and outside being coaxially connected with inside and outside power transmission shaft, described headstock comprises motor, the reductor be connected with motor and drive gear mechanism, described speed reducer output shaft connects intermediate solid drive shaft by shaft coupling, described drive gear mechanism connects outer power transmission shaft, outer drilling pipe is driven to reversely rotate, spray head is provided with below described headstock, spray head is arranged between inside and outside power transmission shaft and inside and outside drilling pipe.
Spray head comprises the inside and outside adapter of coaxial socket, interior extension tube attached upper and lower side respectively with inside and outside power transmission shaft end, inside and outside drilling pipe upper end coaxially connects, described extension tube attached is socketed with hermetically sealed case, the feed pipe for mortar that hermetically sealed case is offered by sidewall, the seal gasket of upper and lower side and upper-lower seal end cap are formed, bearing is arranged with between described upper and lower end cap and upper and lower side seal gasket, described extension tube attached offers the through hole corresponding with feed pipe for mortar, feed pipe for mortar is made to be communicated with gap between interior extension tube attached, seal rubber sleeve above extension tube attached in sealing is set above described through hole, described seal rubber sleeve upper end is provided with bearing.
As preferably, interior extension tube attached upper and lower side is fixedly connected with by arranging adpting flange with inside and outside power transmission shaft end, inside and outside drilling pipe upper end.
The sun gear be fixedly connected with intermediate solid drive shaft is comprised as drive gear mechanism described in another technical problem of solution the present invention, internal tooth is offered inside described sun gear, intermediate solid drive shaft is each side provided with a double end sprocket, described double end sprocket upper end gear all engages with sun gear internal tooth, lower end gear engages with the toothed disc on outer power transmission shaft, drives outer drilling pipe to reversely rotate.
Key problem in technology of the present invention be this transmission refractory gunning equipment use only uniaxial drive twin shaft export drive mechanism mode drive the relative bidirectional rotation of inside and outside drilling pipe, realize the two-way stirring of stake machine, interior drilling pipe adopts the slow-speed of revolution, high moment of torsion, thus raising cutting effect, outer drilling pipe High Rotation Speed, makes the effect be uniformly mixed be improved.Spray head is connected with gear-box dual output axle head, the crack of inner and outer pipes is utilized to whitewash, stop owing to causing the existing picture of inner and outer pipes plugging locking because of bleeding, owing to changing the whitewashing mode of spray head, without the infiltration of slurry inside gear drive, decrease the damage to casing, extend the working time of gear mechanism.Have structure to simplify, energy consumption is little, and efficiently, operating cost is few, easily grasps, and is suitable for the features such as industrial applications.
Beneficial effect of the present invention: bi-directional cement soil mixing pile machine of the present invention have employed single motor (power) single rod rotary drive system, structure greatly simplifies, particularly the improvement to spray head structure will be passed through, and be arranged at below power box, effectively prevent because bleeding causes the existing picture of inner and outer pipes plugging locking, and prevent slurries from revealing in headstock, extend the application life of headstock.Moreover the present invention changes the old model that the inside and outside drilling pipe of conventional drilling machine rotates, and adopts outer drilling pipe only to play a supportive role, the main rotation of interior drilling pipe single pole, and by the technology path that gear train is shunted, realizes the rotation in opposite directions of inside and outside drilling pipe simultaneously.Owing to employing gear drive, this mechanism has the function of commutation, speed change, achieve and turn to contrary inside and outside drilling pipe and the agitating mode of friction speed, improve the effect of the interior pipe cutting moment of torque and outer tube high-speed stirred, thus adapted to the construction of various geological conditions, can guarantee that within the scope of reinforcement depth, the soil body and cement grout stir simultaneously.
