Description

Technical Field

[0001] The invention relates to the field of tower crane safety control, and in particular to a remote control tower crane rotary wind vane release circuit device and a method thereof. Background Art

[0002] Tower cranes (hereinafter referred to as "tower cranes") are important in construction projects, especially in the construction of high-rise buildings. The slewing brake of a tower crane usually adopts a normally closed wind vane brake. In the non-working state, in order to avoid the influence of wind on the tower crane, the slewing wind vane should be opened to allow the tower crane to rotate freely with the wind. If the slewing brake of the tower crane is not opened, in case of bad weather (such as typhoons, storms, etc.), the wind will blow directly to the boom for a long time, which will cause certain damage to the tower structure. In more serious cases, the tower may collapse.

[0003] At present, the release of the tower crane slewing wind vane is mainly operated by the driver after get off work, either electrically or manually, or by the manager remotely through the network platform. These two methods have the following problems:

[0004] (1) The tower crane driver may forget to open the wind vane brake after get off work, and the operator cannot reach the site immediately to climb up the tower crane to release the slewing wind vane brake. In addition, the risk of climbing the tower is greatly increased in bad weather.

[0005] (2) The manager remotely controls the tower crane through the network platform to release the rotating wind vane. This method requires a stable network signal and a stable power supply on site. In severe weather, the network signal and power supply may be cut off. Summary of the invention

[0006] The purpose of the present invention is to provide a remote control tower crane rotary wind vane release circuit device and method thereof, to solve the technical problems mentioned in the background technology. The purpose is to enhance the automatic safety protection capability of the tower crane under severe weather conditions. The combination of UPS power supply and SMS remote control technology can provide a more intelligent and reliable solution for the release of the rotary wind vane of the tower crane, ensuring timely and safe execution of control operations in severe environments.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A remote control tower crane rotary wind vane release circuit device comprises a wind vane release circuit, a UPS power module, a short message receiving module, a control circuit module and a state feedback module, wherein the UPS power module is respectively connected to the wind vane release circuit, the short message receiving module and the control circuit module for power supply, the short message receiving module is connected to the control circuit module, the collection end of the state feedback module is connected to the wind vane release circuit, and the output end of the state feedback module is connected to the control circuit module;

[0009] The UPS power supply module is used to provide uninterrupted power supply to ensure that the system can continue to work when the city power is cut off, thereby ensuring the weather vane release function. The SMS receiving module is used to receive SMS instructions sent by remote users, parse the instruction content and generate corresponding control signals. The control circuit module is used to control the relay to realize the weather vane release function through the signal generated by the SMS receiving module. The status feedback module is used to receive the weather vane release status and feed it back to the remote operator through SMS to ensure closed-loop feedback of the operation.

[0010] Further, the weather vane release circuit includes a weather vane solenoid control relay circuit, a slewing brake control relay circuit, a weather vane solenoid control contactor circuit, a slewing brake control contactor circuit, a slewing brake coil circuit and a weather vane solenoid coil. The weather vane solenoid control relay circuit is connected to the weather vane solenoid control contactor circuit, the slewing brake control relay circuit is connected to the slewing brake control contactor circuit, the slewing brake coil circuit is connected to the slewing brake coil circuit, and the weather vane solenoid coil is connected to the weather vane solenoid control contactor circuit.

[0011] Furthermore, the swing brake control relay circuit includes a relay core 2KA1 and a relay switch 2KA1, and the relay switch 2KA1 is connected to the swing brake control contactor circuit and the wind vane electromagnet control relay circuit respectively.

[0012] Furthermore, the weather vane electromagnet control relay circuit includes a relay core 2KA2 and a relay switch 2KA2, and the relay switch 2KA2 is connected to the weather vane electromagnet control contactor circuit and the relay switch 2KA1 respectively.

[0013] Furthermore, the weather vane release circuit also includes a weather vane feedback switch and a rectifier circuit. The weather vane feedback switch is connected to an external feedback circuit. The slewing brake coil circuit and the weather vane electromagnet coil are connected to the rectifier circuit via the wind vane electromagnet control contactor circuit and the slewing brake control contactor circuit respectively.

[0014] Furthermore, the UPS power module adopts a UPS power device with a capacity of more than 1000VA. When the city power is normally supplied, the UPS power module is charged; when the city power is cut off, the UPS power module maintains the normal operation of the entire device to ensure that the tower crane wind vane can be released in time.

[0015] A method for remotely controlling a slewing wind vane release circuit device of a tower crane. When meteorological monitoring or a severe weather warning is issued, a remote operator sends a text message instruction to a control module of the system via a mobile phone. The text message receiving module of the system generates a control signal after parsing the text message. After receiving the control signal, the control circuit module is powered by a UPS power module to drive the wind vane release device to perform a release action. After the wind vane is released, a state feedback module sends the execution result to the operator via a text message so that the operator can confirm that the operation is completed. If the city power is interrupted in severe weather, the UPS power module will automatically switch to a backup power supply to ensure that the text message control and the wind vane release device can continue to work until the operation is completed.

[0016] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0017] The present invention is remotely controlled, safe and reliable: remote operation is achieved through SMS control, which avoids the risk of operators arriving at the site for manual operation in bad weather; uninterrupted power supply guarantee: compared with traditional tower crane control systems, the UPS power supply module ensures that the system can still work normally even in the event of a power outage, ensuring reliable operation in emergency situations; simple operation and timely feedback: the SMS control module not only supports remote operation, but also provides real-time status feedback, ensuring that the operator can understand the actual status of the tower crane in a timely manner.
