Description
Technical field
The present invention relates to shield machine technical field, the main driving HBW grease injection devices of the more particularly to a kind of shield of improvement
And its control method.
Background technology
Shield machine is usually used in the driving of subway tunnel, seabed tunnel, vcehicular tunnel etc., is a kind of high degree of automation, section
Human-saving, speed of application are fast, cavitation, a weatherproof, when excavating controllable surface subsidence and in underground excavation not
Affect the tunnel construction machinery of traffic above-ground.
The basic functional principle of shield machine be exactly by the shield body of forefront along canal axes when pushing ahead to soil
Excavated, and rotating disk is installed in front of shield body, wear resistant cutters are covered with rotating disk, broken by the rotation and extruding of cutterhead
The broken, soil of chip underground, sandstone and stone etc., the wherein rotation of shield shell are driven by main driving.
At present, during shield machine tunneling construction, the quality of main driveability directly affects shield driving efficiency, main drive
Dynamic damage can more cause shield to tunnel, and have serious consequences, what the damage of main driving was generally caused by bad seals, in a large number
Muddy water by damage sealing ring enter main driving inside, so as to directly result in the parts such as large gear ring, little gear, bearing
Abrasion, causes the damage of main driver part.Therefore, main driving sealing system is the key for protecting main driving in tunneling process
Technology, and the sealing system of traditional flow-control is the method by substantial amounts of discharge HBW oils and fatss, and silt is got lodged in into sealing
The effect for protecting main driving is reached outward.
It is existing it is main drive sealing structural representation as shown in figure 1, it is main driving transcapsidation and shield shell between from inside to outside according to
Secondary to install multi-stage sealed, wherein having HBW oils and fatss chamber at first lip-type packing of main driving, HBW oils and fatss are direct with dregs
Contact, the uniform multiple grease injection ports in HBW oils and fatss chamber（One is only shown in figure）, the continuous HBW oils and fatss extruded are utilized by dregs
Gear is outside main driving.To ensure the sealing effectiveness of HBW, injection HBW oils and fatss in the country generally adopt flow control methods, i.e., regardless of knife
The pressure of Tu Cang is how at disk, and the oil quantity of extrusion is equal, and the method cannot accurately be exported according to the practical situation of geology, because
It is larger that this causes oils and fatss to waste.In the case of simultaneously incrusted outside HBW oils and fatss chamber, the outlet obstruction in HBW oils and fatss chamber, oils and fatss without
Method is discharged in time, causes seal pressure excessive, and so as to cause oils and fatss to flow back, sealing rollover has larger potential safety hazard.
In consideration of it, the present inventor develops a kind of main driving HBW grease injection devices of shield of improvement and its control for this
Method, effectively solves the problems referred to above, and thus this case produces.
The content of the invention
The main driving HBW grease injection devices of shield and its control method of a kind of improvement that the present invention is provided, according to Tu Cang
Interior pressure come change HBW oils and fatss injection pressure, so as to be accurately controlled the injection rate of HBW oils and fatss, to reduce HBW oils and fatss
Consumption, reduction construction cost.
To achieve these goals, technical scheme is as follows：

The controller and shield machine main drive signal connection, controller detect the HBW pressure of grease more than etc.
When the pipeline blockage judgment value of setting, control Pneumatic grease pump and electrical ball valve quit work, while main driving of control stops
Work.
Also include alarm, be installed on shield machine and drive indoor, and connect with controller signals, controller detects described
When HBW pressure of grease is more than or equal to presetting pipeline blockage judgment value, alarm equipment alarm is controlled.
The presetting maximum difference and presetting minimal difference are respectively the maximum peace of HBW oils and fatss intracavity lip-type packings
Total head and minimum guard value.
A kind of control method of the main driving HBW grease injection devices of the shield of improvement, rate-determining steps are：
S1 controllers control electrical ball valve is opened, and controls aerodynamic grease pump work；
S2 starts shield owner and drives；
