When working, the wire rope protection device is installed on the tower boom 2, and can also be threadedly connected through the legs of the boom 1. The boom 1 and the tower boom 2 constitute the working platform of the entire wire rope protection device, and the wire rope protection device can be placed in the most suitable position, so that the wire rope protection device has the advantages of being portable and easy to move.

[0031] like Figure 2 As shown, the wire rope damage detection system includes an alarm 5 and an ultrasonic sensor 6. The ultrasonic sensor 6 is installed below the support platform 4 and directly facing the wire rope 11. Therefore, the wire rope 11 is always within the detection range of the ultrasonic sensor 6 during operation. The ultrasonic sensor 6 is connected to the alarm 5. The alarm 5 is installed above the support platform 4 and is in a straight line with the ultrasonic sensor 6 below. The wire rope 11 will pass through the ultrasonic sensor 6 in sequence during operation. If there is no damage on the surface or the damage is within a safe range, it will continue to move forward. If the damage on the surface exceeds the threshold, the ultrasonic sensor 6 will transmit a signal to the controller 7. After receiving the signal, the controller 7 will transmit the instruction to the alarm 5, thereby sounding an alarm, indicating that the surface damage of the wire rope 11 has reached the threshold, thereby ensuring work safety.

[0032] like Figure 2 As shown, the anti-rust and anti-corrosion system includes an anti-corrosion coating storage cabinet 12 and a nozzle 13. The anti-corrosion coating storage cabinet 12 is installed above the support platform 4. The nozzle 13 is connected to the anti-corrosion coating storage cabinet 12 and is installed side by side with the oil dripper 9 in a straight line, located above the steel wire rope 11.

The stop spring 34 can eliminate the impact and buffering force during the filling process, and play a role in protecting the lubrication device. When the lubrication system is working, the oil pump 36 provides power, and the lubricating oil flows through the first oil delivery pipe 35 and the second oil delivery pipe 37 to reach the pressure gauge 8, and finally flows out from the oil dripper 9 according to the set pressure and finally reaches the surface of the wire rope 11.

[0035] like Figure 4 As shown, in order to filter the lubricating oil, a filtering device is also included, the filtering device includes a filter screen fixing mechanism 21 and a filter screen 22, one end of the filter screen 22 extends into the oil tank 3, and the other end is connected to the filter screen fixing mechanism 21, and the filter screen fixing mechanism 21 is installed on the support platform 4.

[0037] The specific operations of the controller 7 include:

[0038] When inputting oil into the oil tank 3, press the "oil filling" button on the far right of the operation panel of the controller 7, and then the lubricating oil is injected through the oil filling port 30, passes through the first oil filling pipe 31 and the second oil filling pipe 32 in sequence, and finally flows into the oil tank 3; when lubrication work is required, turn on the controller 7, select the working mode on the controller 7 first, and then the oil supply rate of the oil pump 36 can be adjusted in the automatic lubrication mode.

[0039] When the oil supply rate needs to be adjusted, first press the "SET" key on the operation panel of the controller 7. After pressing the "SET" key, the left screen flashes first. The left screen is for working mode selection, and the right screen is for working parameter adjustment under the selected working mode. First select the working mode, and you can adjust the working parameters by pressing the "Δ" and After selecting the working mode, press the "SET" key again to successfully set the working mode. After setting the working mode, the right screen flashes, and you can use the "Δ" and The oil supply rate of the oil pump 36 can be adjusted by pressing the "Δ" key to increase the oil pumping rate of the oil pump 36. The oil pumping rate of the oil pump 36 can be reduced by pressing the "SET" key. When the required oil pumping rate is adjusted, press the "SET" key again to complete the setting of the oil supply rate. The lubricating oil then passes through the oil pump 36 and enters the oil pipe 37. The pressure gauge 8 monitors the pressure of the lubricating oil in real time, and the lubricating oil is evenly dripped onto the surface of the wire rope 11 through the oil dripper 9.

[0040] The automatic lubrication system can be started according to different working needs such as the agreed time or the wire rope use cycle. Long press the "SET" button on the operation panel of the controller 7, and the mode selection will appear on the left screen of the operation panel of the controller 7. Select the required mode. After selecting the working mode, the right screen lights up, and then you can set the parameters in the working mode. It can realize the working needs such as timed lubrication and lubrication during work.

[0041] The method of using this device is:

[0042] First, the wire rope lubrication device is placed on a working platform composed of the boom 1 and the tower crane arm 2, and then the relative position with the wire rope 11 is corrected. After the position correction is completed, it can be screwed to the platform through its base.

[0043] After the connection is completed, start the oil filling mode on the far right of the controller 7, and fill the oil through the oil filling port 30. The oil filling port 30 is installed on the controller 7. The lubricating oil enters the first oil filling pipe 31 through the oil filling port 30, and enters the second oil filling pipe 32 through the first oil filling pipe 31. The float 33 placed at the bottom of the oil filling pipe 32 is used for marking and positioning. The brake spring sheet 34 eliminates impact and buffering force during the oil filling process.

[0044] After the lubricating oil is injected, start the system. The left screen flashes. Press and hold the "SET" button on the controller 7 and press "Δ" and Press the "SET" key to select the mode. This time, the automatic lubrication mode is selected. After selecting the mode, press the "SET" key again. The mode setting is completed, and the right screen starts to flash. Set the required working parameters according to the needs of this work. After the setting is completed, the oil pump 36 starts, and the lubricating oil passes through the filter of the oil delivery pipe 35 and enters the oil pump 36. Then, it enters the oil filling pipe 37 through the oil pump 36. The pressure gauge 8 is set on the passage of the oil filling pipe 37 to monitor the pressure value in real time. The lubricating oil drips on the wire rope 11 through the oil dripper 9.

[0045] If the ultrasonic sensor 6 detects that the degree of damage to the wire rope exceeds a threshold value during operation, it will transmit a signal to the controller 7, and the controller 7 will issue an instruction to the alarm 5. After receiving the signal, the alarm 5 will sound an alarm to indicate that the wire rope 11 needs to be repaired.

[0046] When the steel wire rope 11 needs to be treated for rust and corrosion prevention, the corresponding mode can be selected on the controller 7, and then the system can be started after adding paint to the anti-corrosion coating storage cabinet 12. The coating paint is sprayed out through the nozzle 13 and evenly applied to the surface of the steel wire rope 11.
