Abstract
The utility model relates to an independent hydraulic driving mud shield stirring machine, which belongs to the technical field of the design and the manufacture of a shield tunneling machine. The utility model is characterized in that a motor is a hydraulic motor which is assembled in an inclined shaft mode, and an external spline of an output shaft of the motor is connected with an internal spline of the input end of a planet speed reducer; one end of a transition shaft for transferring force moment is connected with the internal spline of the output end of the speed reducer, and the other end is connected with the internal spline of a shaft coupling outside the input end of the shield stirring machine, wherein both ends of the transition shaft are provided with the external splines; two spacer flanges with circular disc class structures are mutually connected; a shield stirring machine hydraulic power station which is arranged in a shield body is connected with the hydraulic motor by a hydraulic hose. After the utility model is implemented, the situation that the hydraulic motor is damaged is prevented, releasing torsion is enhanced, the utility model can not frequently generate fault caused by soaking, and thus, the reliability of construction and construction quality are enhanced.
Description
Technical field
Belonging to shield excavation machine design and fabrication technology field, exactly is a kind of design and fabrication technology of blender apparatus of slurry shield development machine.
Background technology
The main effect of slurry shield development machine mixer is that the big clod that enters the mud separation through grid extruding or knife cutting etc. is cut apart and stirred, prevent that native sand precipitation, the obstruction of spoil disposal suction inlet and mud pipe in the cabin are not smooth, it is the critical component that guarantees the normal operation of shield structure muddy water circulatory system, be installed near the bottom spoil disposal suction inlet of mud separation, quantity is decided on shield structure diameter, is generally the 2-4 platform.
The slurry shield mixer has replaced hydraulic-driven by Motor Drive gradually both at home and abroad in recent years, and its main cause has two: the first, and motor drive arrangement is simple, cost is low relatively; Second, shield structure hydraulic power unit all is installed on the follow-up equipment chassis, generally speaking, starting the stage of appearing in shield structure down-hole, the follow-up equipment chassis is interim to be placed on the ground, its up and down difference in height can reach more than the 10m, and the back pressure that the above discrepancy in elevation of 10m and long interim fluid pressure line form is enough to make the mixer hydraulic drive motor to damage because of the oil pressure of drain tap exceeds standard.
Although be widely used, still there is bigger deficiency in the mixer Motor Drive.At first, with respect to hydraulic-driven, its moment of torsion of getting rid of poverty is much smaller, is difficult to handle the special circumstances that run into bulk foreign matter etc.Second, the designed lines of most of shield tunnel all contains the gradient up and down, when descending is constructed, tends to produce at short notice a large amount of ponding in the slurry shield, the mixer drive motors that will be in lower position floods fully, and easily makes motor produce fault and can't operate as normal.
Summary of the invention
The utility model provides and a kind of hydraulic power unit is installed in shield structure inside, thereby can avoid the hydraulic drive motor oil pressure to exceed standard, and can bring into play the get rid of poverty a kind of slurry shield mixer by independent hydraulically controlled driving of the big advantage of moment of torsion of hydraulic-driven again.
Technical solution adopted in the utility model: by motor, reductor and shield structure mixer, and be provided with a shield structure mixer hydraulic power station, it is installed in the shield structure body.Its structure assembly relation is: motor is the hydraulic motor of clino-axis type assembling, and its output shaft external splines is connected with the internal spline of planetary reducer input; Carry-over moment is used, two ends all are the transition axises of external splines, and an end links to each other with the internal spline of reductor output, and the other end links to each other with the internal spline of shield structure mixer input outside shaft coupling.Two all is that the counter flange of disc-like structure is connected to each other, and the other end separately is respectively that a counter flange links to each other with shield structure mixer; Another counter flange links to each other with reductor.Be installed in the intrinsic shield structure of shield structure mixer hydraulic power station, link to each other with hydraulic motor by hydraulic hose.
After implementing the utility model, because hydraulic power unit is installed in shield structure inside, avoided existing hydraulic-driven form easily to damage the situation of hydraulic motor in the shield structure stage of appearing because of back pressure is too high, compare with the Motor Drive mode simultaneously, the moment of torsion of getting rid of poverty improves greatly, and can not improve the reliability and the construction quality of construction because of immersion often produces fault.

Fig. 2, free-standing mixer hydraulic system schematic diagram
The specific embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings:
The free-standing mixer hydraulic power station of forming by fuel tank 15, ball valve 16, hydraulic variable displacement pump-group of motors 17, one way valve 30, overflow valve 27, solenoid operated directional valve 20, ball valve 19, cooler 29, oil return oil filter 18, pressure sensor 22, stop valve 23, damp type pressure meter 24, stop valve 25, being installed in shield structure inside is positioned on the platform on mixer top, link to each other with the hydraulic fluid port of inclined shaft type hydraulic motor 1 by hydraulic hose 21, stop valve 26, revolution detector 28 is housed on reductor 2.Hydraulic variable displacement pump-group of motors 17 is major impetus sources of this open type hydraulic system, can change the rotating speed of mixer by the output discharge capacity of adjusting inclined disc type hydraulic variable displacement pump, can change the moment of torsion of mixer by the set pressure of adjusting overflow valve 27, can change the direction of rotation of mixer by the commutation of switching solenoid operated directional valve 20, cooler 29 is by being connected with cooling water channel in the shield structure, be used to reduce the temperature of hydraulic oil, can guarantee the reliability service of hydraulic system, the effect of oil return oil filter 18 is the cleannes that keep hydraulic oil, stop valve 23 and stop valve 25 are as manometric switch, with ball valve 16, stop valve 26 is the same, can conveniently debug or keep in repair, hydraulic power station with adopt hydraulic hose 21 during the pipeline of hydraulic motor 1 is connected, can convenient for maintaining and shock-absorbing.
The mixer hydraulic power station is installed in shield structure body interior, separates with other dynamical systems of shield structure; Shown in the figure is hydraulic control system at 3 mixers, if mixer quantity difference only needs the quantity of hydraulic circuit and hydraulic unit among the corresponding increase and decrease figure.
