[0002] In the operation of crawler crane double winding hook, due to the complexity of the working environment and the unstable factors or misoperation that may occur during the operation, the synchronous action of winding the wire rope cannot be guaranteed. This may cause the wire rope to be wound randomly, or even cause wire rope damage or more serious safety accidents. At present, the monitoring of wire rope status in crawler crane operation mainly relies on the operator's visual observation and experience judgment, and there is a lack of effective automated monitoring means to prevent and reduce such risks.

[0003] Therefore, there is an urgent need to design an anti-rope tangle monitoring system and method for the double-winding hook of a crawler crane to solve the above-mentioned problem that the monitoring of the winding wire rope mainly relies on the operator's visual observation and experience judgment, with low degree of automation and high risk. Summary of the invention

[0004] In order to solve the technical problems mentioned in the background technology that the monitoring of wire rope threading and winding mainly relies on the operator's visual observation and experience judgment, with low automation and high risk, a rope tangle prevention monitoring system and method for a double-winding threading hook of a crawler crane is provided to solve the above problems.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the anti-tangling rope monitoring system and method of the crawler crane double winding hook of the present invention is as follows: A rope tangle prevention monitoring system for a double-winding hook of a crawler crane comprises a fixed shell, which is arranged on a movable pulley of a hook head. A monitoring equipment box is arranged in the fixed shell, and a power supply, a first signal transmitting module and a first relay are arranged in the monitoring equipment box. The first signal transmitting module and the first relay are connected in series to the power supply, and a position sensor is also connected in parallel to the power supply. The position sensor is arranged at the movable pulley of the hook head and is used to detect the horizontality of the hook head. The position sensor is also connected to the first relay, and also comprises a first signal receiving module and a first alarm module. When the position sensor detects that the movable pulley of the hook head is tilted, the first relay is energized and closed to activate the first signal transmitting module. The first signal transmitting module sends an alarm signal, and the first signal receiving module receives the signal to make the first alarm module alarm.

[0006] Furthermore, a second signal transmitting module and a second relay are also provided in the monitoring equipment box. The second signal transmitting module and the second relay are connected in series to the power supply. A voltage detection module is also connected in parallel to the power supply. The voltage detection module is used to detect the voltage of the power supply. The voltage detection module is also connected to the second relay. It also includes a second signal receiving module and a second alarm module. When the voltage of the power supply drops below a preset safety threshold, the second relay is energized and closed to activate the second signal transmitting module. The second signal transmitting module sends an alarm signal, and the second signal receiving module receives the signal to cause the second alarm module to alarm.

[0007] Furthermore, the first signal receiving module, the second signal receiving module, the first alarm module and the second alarm module are all placed in the cockpit.

[0012] Furthermore, the position sensors include two, and the two position sensors are respectively arranged on both sides of the hook movable pulley.

[0013] A method for monitoring the anti-tangling of ropes of a crawler crane double-winding hook comprises the following steps: S1: The position sensor monitors the horizontality of the hook movable pulley in real time. When the wire rope is loose and causes the movable pulley to tilt, the position sensor triggers the first relay; S2: The first relay activates the first signal transmitting module to transmit the alarm signal to the first signal receiving module; S3: The first signal receiving module receives the alarm signal, triggering the first alarm module to alarm; S4: The driver stops working after receiving the alarm.

[0014] Further, the method further comprises the following steps: S5: The voltage detection module detects the power supply voltage in real time. When the voltage is lower than the safety threshold, the voltage detection module triggers the second relay; S6: The second relay activates the second signal transmitting module to transmit the alarm signal to the second signal receiving module; S7: The second signal receiving module receives the alarm signal, triggering the second alarm module to send out a low battery alarm signal; S8: The driver charges the power supply in time after receiving the alarm.

[0015] The anti-rope disorder monitoring system and method for the crawler crane double-winding hook of the present invention has the following advantages: By setting a position sensor at the movable pulley of the hook head to detect the horizontality of the hook head, when the position sensor detects that the movable pulley of the hook head is tilted, the first relay is energized and closed, activating the first signal transmitting module, the first signal transmitting module sends an alarm signal, and the first signal receiving module receives the signal to make the first alarm module alarm, and then real-time monitoring and alarm can be performed. Through real-time monitoring and timely alarm, the safety of crawler crane operation is significantly improved, and the rope tangling phenomenon caused by loose wire rope is effectively avoided. The degree of automation is high and the construction risk is reduced.

[0016] By setting up a voltage detection module, the voltage detection module is used to detect the voltage of the power supply. When the voltage of the power supply drops below a preset safety threshold, the second relay is energized and closed, activating the second signal transmitting module. The second signal transmitting module sends an alarm signal, and the second signal receiving module receives the signal to make the second alarm module alarm, thereby ensuring that the driver can understand the battery status of the monitoring system in a timely manner and avoid work interruption due to insufficient power.
