Fig. 1 and 2 are a flow chart and logic intent of an anti-misoperation method for an electro-hydraulic jumbolter provided by an embodiment of the present invention. The method comprises the following steps:
step 101, when the anchor box is retracted along the advancing direction after the damping type torque nut is screwed up, the distance between the connecting sleeve and the advancing direction of the nut is monitored in real time;
In the embodiment, the distance between the connecting sleeve and the advancing direction of the nut is monitored through a displacement sensor or an encoder, the initial working position of the connecting sleeve is preset to be a displacement zero point, the measured value is larger than or equal to 0, the preset connecting sleeve is at a maximum displacement point at the screw tightening position, the displacement sensor or the encoder measures the increase of a displacement value to indicate that the connecting sleeve advances along the advancing direction, the displacement sensor or the encoder measures the decrease of the displacement value to indicate that the connecting sleeve retreats along the advancing direction, and when the connecting sleeve retreats along the advancing direction, the difference between the displacement maximum value and the current displacement value of the connecting sleeve is the distance between the connecting sleeve and the advancing direction of the nut.
The method comprises the steps of judging whether the distance between the connecting sleeve and the nut in the advancing direction continuously increases, and specifically, judging whether the distance between the connecting sleeve and the nut in the advancing direction continuously increases to indicate that the connecting sleeve normally retreats and a displacement sensor or an encoder has no fault, if the judging result is that the distance between the connecting sleeve and the nut does not continuously increase, reporting the fault, and ending the automatic supporting flow of the automatic jumbolter.
And 102, opening a flushing loop electromagnetic control valve of the anchor box if the propulsion direction distance meets the preset propulsion direction distance condition, and further monitoring the flushing fluid flow through the flushing loop in real time.
The preset advancing direction distance in the embodiment is 1.5 times of the distance between the tail of the anchor rod body and the end face of the connecting sleeve when the nut is screwed, and is related to the length of the threaded section of the tail of the anchor rod body, and the fact that the advancing direction distance is larger than the preset advancing direction distance indicates that the part of the anchor rod body inserted into the anchor box is completely separated from the anchor box. If the result is yes, the electromagnetic control valve is opened to enable the flushing loop to be connected, and the flow of flushing liquid is further monitored, and in the embodiment, the monitoring of the flow of the flushing liquid is achieved through the flow sensor.
Before the step of monitoring the flow rate of the flushing liquid in real time, the step of operating the pressure valve according to the preset pressure is further performed, wherein the preset pressure is generally not more than 0.5Mpa.
The step of opening the electromagnetic control valve of the flushing loop of the anchor box further comprises the step of judging whether the electromagnetic control valve is normally opened or not, wherein in the embodiment, the opening monitoring of the electromagnetic control valve is realized through a second pressure sensor connected behind a second port of the electromagnetic control valve, a measured pressure value is equal to the preset pressure to indicate that the electromagnetic control valve is normally opened, a measured pressure value is 0 to indicate that the electromagnetic control valve is failed to be opened, if the judgment result is that the electromagnetic control valve is failed to be opened, the failure is reported, and the automatic supporting flow of the automatic jumbolter is ended.
Before the step of opening the flushing loop electromagnetic control valve of the anchor box, the method further comprises the step of judging whether the flushing fluid source is liquid or not, wherein the measured pressure value is 0, which indicates that the flushing fluid source is free of the flushing fluid source, through the first pressure sensor, if the judgment result is that the flushing fluid source is free of the flushing fluid source, a fault is reported, and the automatic supporting flow of the automatic jumbolter is ended. The flushing liquid can be clear water, emulsion, hydraulic oil or solution with special proportion.
And 103, closing the electromagnetic control valve if the flow rate of the flushing liquid meets the preset value.
In the embodiment, the preset flushing liquid flow value is 10L/min, the measured value of the flow sensor is larger than the preset value to indicate that the cleaning of the damping body is completed, the electromagnetic control valve is closed to stop flushing, and if the damping body is judged to be not cleaned, the operating pressure of the pressure valve is automatically regulated, so that the impact force of flushing liquid is further increased, and the cleaning of the damping body is easier to realize.
In order to realize the embodiment, the invention also provides a system for automatically cleaning the ejected anchor rod torque nut damping body, the principle of which is shown in fig. 3, and the system comprises:
The flushing fluid source 201, the pressure valve 202, the electromagnetic control valve 204, the first pressure sensor 203, the second pressure sensor 203, the flow sensor 205 and the anchor box transmission shaft 206 are all two ports, flushing fluid flows in from a first port of an element and flows out from a second port of the element, the elements are sequentially connected to form a flushing loop, the first pressure sensor 203 is connected between a second port of the pressure valve 202 and a first port of the electromagnetic control valve 204 in parallel, the second pressure sensor 203 is connected between a second port of the flow sensor 205 and a first port of the transmission shaft 206 in parallel, and the transmission shaft 206 and the displacement sensor 207 are fixed together.

Further, the flushing liquid enters the cavity formed by the damping body 7 and the counter bore 20611 after passing through the communication hole 2062 and the bottom hole 20612, a part of the flushing liquid flows out through the annular gap, a part of the flushing liquid acts on the lower surface of the damping body to form impact force, the impact force is proportional to the operating pressure of the pressure valve 202, when the pressure valve 202 operates according to the preset pressure, the damping body 7 floats from the counter bore 20611 to the upper end surface of the connecting sleeve at a very small speed, and in order to ensure successful cleaning of the damping body 7, the operating pressure of the pressure valve 202 needs to be regulated afterwards, and the flushing liquid flow is correspondingly increased.
Wherein, the diameter of the damping body 7 is changed along with the specification of the torque nut 4 by the threaded fit of the damping body 7 and the torque nut 4, correspondingly, the diameter of the counter bore 20611 is serialized along with the specification of the torque nut 4, further, the diameter of the transmission shaft 206 is serialized along with the serialization of the diameter of the counter bore 20611, in particular, the torque nut 4 with one specification is screwed, and one transmission shaft 206 is correspondingly configured.
