Detailed Implementation

[0023] Please refer to the following: Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the present invention; Figure 2 for Figure 1 A magnified structural diagram of the middle two parts; Figure 3 This is a schematic diagram of the cable clamping device in this utility model; Figure 4 This is an assembly diagram of the clamp head, round rod, moving block, mounting block, and rotating shaft in this utility model. The tower crane jacking main cable status management device based on intelligent monitoring includes: a monitoring mechanism 2 installed on the tower crane body 1, the monitoring mechanism 2 consisting of a cable clamping device 3, a main cable 4, control equipment 5, and an audible and visual alarm 6. The tower crane body 1 is equipped with a mounting frame, and the cable clamping device 3 is installed in the mounting frame.

[0024] The cable clamping device 3 includes several parts: clamp head 31, mounting block 32, rotating shaft 33, clamp head 35, hydraulic cylinder 37, mounting base 38, mounting base 39, round rod 311, and moving block 312.

[0025] The mounting block 32 is mounted on the sleeve, and the first pliers 31 is mounted on the mounting block 32 via a rotating shaft 33. The first pliers 31 is adapted to the mounting block 32.

[0026] The second pliers head 35 is mounted on the sleeve frame. The second pliers head 35 is located on one side of the first pliers head 31. The outer walls of the first pliers head 31 and the second pliers head 35, which are close to each other, are respectively provided with a wire clamping groove 1 and a wire clamping groove 2.

[0027] Both the first and second clamping grooves are provided with grooved threads to increase friction. These grooved threads are used to enhance the clamping effect and prevent the cable from slipping.

[0028] A groove is provided on the outer wall of the first pliers 31 away from the second pliers 35. The round rod 311 is installed in the groove, and the moving block 312 is slidably installed on the round rod 311. The moving block 312 is adapted to the groove.

[0029] The first mounting base 38 is mounted on the moving block 312, the second mounting base 39 is mounted on the tower crane body 1, the bottom end of the hydraulic cylinder 37 is connected to the second mounting base 39, and the output shaft of the hydraulic cylinder 37 is connected to the first mounting base 38.

[0030] The control device 5 is mounted on the frame and consists of a sensor 51 and a controller 52, both of which are mounted on the frame.

[0031] The audible and visual alarm 6 is installed on the frame.

[0032] The cable clamp 3 can be equipped with a self-locking device to lock the position in the event of a power outage, preventing the cable from falling off due to loosening.

[0033] The sensor 51 can be a ZNLBM-100 tension sensor. This model of sensor has the characteristics of high measurement accuracy, fast response speed and good stability. It can monitor the clamping force and lifting force of the cable clamp 3 on the main cable 4 and is suitable for complex construction environments such as tower cranes.

[0034] The controller 52 can be a Siemens S7-1200 series PLC controller, such as CPU1214C, which has strong computing and data processing capabilities, can quickly receive data transmitted by sensor 51 and perform analysis and calculation, and has good expandability and reliability, and can stably control the operation of equipment such as electric telescopic pole 37 and audible and visual alarm 6.

[0035] The working principle of the tower crane jacking main cable status management device based on intelligent monitoring provided by this utility model is as follows:

[0036] First step: The equipment clamps the main cable 4 through the cable clamp 3, starts the operation of the hydraulic cylinder 37, and its output shaft extends and retracts to drive the mounting base 38 to move, thereby causing the moving block 312 to slide on the round rod 311, causing the clamp head 31 to rotate around the rotating shaft 33, and cooperate with the clamp head 35 to clamp the main cable 4 through the clamping groove 1 and clamping groove 2. The threaded screw is used to enhance the clamping effect and prevent the cable from slipping. The cable can be lifted synchronously through the lifting action of the sleeve.

[0037] The second step: Sensor 51 in control device 5 monitors the clamping force and lifting force of cable clamp 3 on main cable 4 in real time and transmits the monitoring data to controller 52. Controller 52 calculates the theoretical weight and corresponding theoretical clamping force and lifting force based on the length of main cable 4. When the ratio between the actual clamping force or lifting force monitored by sensor 51 and the theoretical value calculated by controller 52 is abnormal, that is, when the actual force value increases abnormally, controller 52 determines that main cable 4 may be stuck. It then controls the audible and visual alarm 6 to issue an alarm signal and controls the hydraulic cylinder 37 to stop operating, so that cable clamp 3 stops clamping and lifting main cable 4 to avoid main cable 4 breaking due to excessive tension. The alarm signal can also remind the operator to stop the lifting operation.
