Abstract
The utility model discloses a system for helping a cutterhead of a shield tunneling machine with the diameter of 2 meters out of jam. The system comprises a programmable logic controller (PLC), wherein the PLC is connected with an electro-hydraulic reversing valve, an electromagnetic proportion reversing valve and an electromagnetic reversing valve as well as a sensor distributed on an oil path respectively and is also connected with a touch screen. The system has the advantages that under the condition that the cutterhead is in jam, the torque of the cutterhead can be increased conveniently and quickly within a short time, so that the cutterhead can get out of jam; in a jam removal mode, the PLC automatically starts a high-pressure mode of a hydraulic pump, so that pressure required by jam removal can be increased under the condition that the driving power of the whole system is not changed; and a using test shows that the jam removal mode is started under the condition that the jam of the cutterhead is simulated, and the cutterhead can successfully get out of jam within a short jam removal time.
Description
Technical field
The utility model belongs to the tunnel construction machinery equipment technical field, is the electric actuation techniques of a kind of cutter head of shield machine hydraulic pressure, is used for two meters multi-functional balancing earth-pressure shielding machines of diameter.
Background technology
Existing two meters cutter head of shield machine systems of getting rid of poverty of diameter improve moment of torsion by the output quantity that increases hydraulic pump or the aperture opening ratio of scaling up valve, and the speed that therefore this system improves moment of torsion is all slow, can not satisfy the requirement that when getting rid of poverty moment of torsion is improved the time.
The utility model content
The utility model has overcome shortcoming of the prior art, and two meters cutter head of shield machine of a kind of diameter system that gets rid of poverty is provided, and the aperture of controlling one group of valve by PLC realizes that the short time improves the requirement of moment of torsion.
The technical solution of the utility model is: two meters cutter head of shield machine of a kind of diameter system that gets rid of poverty, comprise the PLC controller, and described PLC controller links to each other with sensor on being distributed in oil circuit with electro-hydraulic reversing valve, solenoid-operated proportional reversal valve, solenoid operated directional valve respectively.
Described PLC controller also links to each other with touch-screen.
Described sensor comprises pressure sensor and speed probe.
Compared with prior art, the utility model has the advantages that: can be comparatively quickly and easily in the situation that the stranded short time raising of cutterhead cutterhead moment of torsion, make cutterhead above water, when entering when getting rid of poverty pattern, the high pressure mode of the automatic primer fluid press pump of PLC, can in the situation that the whole system driving power is constant, increase the required pressure of getting rid of poverty.Through use test, in the situation that the simulation cutterhead is stranded, (the normal operating cutterhead can't rotate) starts the pattern of getting rid of poverty at operating desk, and cutterhead is got rid of poverty smoothly, and the time of getting rid of poverty is short.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is system architecture schematic diagram of the present utility model.
The specific embodiment
Two meters cutter head of shield machine of a kind of diameter system that gets rid of poverty as shown in Figure 1, comprises PLC controller and the touch-screen that links to each other with the PLC controller respectively, pressure sensor, speed probe, electro-hydraulic reversing valve, solenoid-operated proportional reversal valve and solenoid operated directional valve etc., wherein:
Pressure sensor and speed probe are distributed on the oil circuit, are respectively applied to gather pressure signal and tach signal, and signal is exported to the PLC controller, and the PLC controller calculates torque value, and torque value is exported to touch-screen (man-machine interface).Operating personnel judge according to the parameter that touch-screen shows whether cutterhead stranded, and when cutterhead is stranded the startup pattern of getting rid of poverty, make the PLC controller place meta by switching value signal controlling electro-hydraulic reversing valve, make electromagnet must not be in electricity condition; The PLC controller is regulated solenoid-operated proportional reversal valve YA1 by the 4-20mA current signal simultaneously, makes current signal value to minimum; Then the PLC controller switches solenoid operated directional valve YA4 by the switching value signal again, electromagnet is got electric, to enable the high pressure mode of pump; At last, the PLC controller is regulated solenoid-operated proportional reversal valve YA1 to the force value of getting rid of poverty (22MPa) by the 4-20mA current signal again.
The utility model gets the electric high pressure mode that enters hydraulic pump by solenoid operated directional valve YA4 under the pattern of getting rid of poverty, come the short time to improve the moment of torsion of cutterhead.The high pressure mode that has increased solenoid operated directional valve YA4 pump with respect to original design is selected, can be in the situation that the constant pressure that improves of power finally makes motor torsional moment increase substantially in the short time.
Claims (3)
1. two meters cutter head of shield machine of diameter system that gets rid of poverty is characterized in that: comprise the PLC controller, described PLC controller links to each other with sensor on being distributed in oil circuit with electro-hydraulic reversing valve, solenoid-operated proportional reversal valve, solenoid operated directional valve respectively.
