Description
Technical field
The crawler belt that the utility model relates to a kind of engineering machinery detects and safety control system, and particularly a kind of rotary drilling rig crawler belt detects and safety control system.
Background technology
The crawler belt of the rotary drilling rig two states of stretching out and withdraw, during the crawler belt withdrawal, rotary drilling rig walks, up and down flat car, shift place etc.; When crawler belt was stretched out, rotary drilling rig carried out construction operations such as vertical drill mast, boring.If crawler belt is not stretched out just erect bore mast and hole, construction operation such as revolution because the stability of complete machine reduces, ill effect such as very easily cause that rig is tumbled.For unskilled rig tractor driver,, can not stretch out crawler belt and just construct owing to careless and inadvertent in the construction owing to lack experience.Therefore, rig is carried out the flexible state-detection of crawler belt and carries out corresponding automatic safe control, can avoid the generation of great overturn accident.
The utility model content
The purpose of this utility model is to provide a kind of: the rotary drilling rig crawler belt detects and safety control system, separate never crawler belt is stretched out just erect bore mast and hole, construction operation such as revolution, and the problem that causes rig to tumble.
The purpose of this utility model is achieved in that this control system comprises that contract electromagnetic valve, left cylinder of power switch, battery, ultrasonic sensor, obliquity sensor, first terminal resistance, second terminal resistance, controller, rotary magnetic valve, relay, left cylinder stretch contract electromagnetic valve, right cylinder of electromagnetic valve, right cylinder and stretch electromagnetic valve
The negative pole of battery is by power switch ground connection, and the positive pole of battery connects the X4.4 end of controller, and the positive pole of battery also connects 1 end of ultrasonic sensor and the anode of obliquity sensor simultaneously; The X2.4 end of controller is by the coil ground connection of relay; One end of the constant close contact of relay is connected with the positive pole of battery, other end series connection rotary magnetic valve ground connection; 3 ends of the negative terminal of obliquity sensor, the X4.1 of controller end and ultrasonic sensor are ground connection simultaneously, and 2 ends of ultrasonic sensor connect the X1.10 end of controller; The H of obliquity sensor, L end is connected respectively to X4.7, the X4.8 end of controller, and two ends are connected with first terminal resistance and second terminal resistance in parallel; The X1.5 of controller, X1.6, X1.7, X1.8 end is stretched electromagnetic valve, the right cylinder electromagnetic valve that contracts and is stretched with right cylinder that electromagnetic valve is corresponding to be connected with contract electromagnetic valve, left cylinder of left cylinder respectively.
Beneficial effect, when crawler belt is stretched out, ultrasonic sensor detects signal and is input to the X1.10 end of controller, this moment, the X2.4 of controller held no-output, the constant close contact closure of relay, contract electromagnetic valve, left cylinder of rotary magnetic valve operate as normal, left cylinder stretched contract electromagnetic valve and right cylinder of electromagnetic valve, right cylinder and stretched the electromagnetic valve operate as normal, and rig does not limit any action; When crawler belt was withdrawn, ultrasonic sensor detected less than signal, and the X1.10 of controller holds no input signal, and this moment, controller detected the angle of boring mast by obliquity sensor, and when boring the mast angle more than or equal to 30 °, rig stability does not better limit any action; When boring the mast angle less than 30 °, the rig poor stability, this moment, the X2.4 of controller held output voltage signal, and relay gets electric, and the constant close contact of relay disconnects, the rotary magnetic valve dead electricity, rig can not turn round; Simultaneously, contract electromagnetic valve, left cylinder of the X1.5 of controller, X1.6, X1.7, X1.8 terminal non-output signal, left cylinder stretched contract electromagnetic valve and right cylinder of electromagnetic valve, right cylinder and stretched the electromagnetic valve dead electricity, bores the mast akinesia.At this moment, rig can not turn round, and bores mast and can not move, rig just can't be constructed like this, has guaranteed rig in the crawler belt safety during extended state not, has stopped the hidden danger of tumbling, and has realized the security control function of rig.Separate never crawler belt is stretched out just erect bore mast and hole, construction operation such as revolution, and the problem that causes rig to tumble has reached the novel purpose of this reality.
Advantage: control system safely and effectively, by detecting the flexible state of crawler belt, corresponding security control is carried out in the action of rig, when operate miss occurring, guaranteed rig safety.
