[0022] Explanation of the accompanying drawings: 1. Acquisition module; 2. Data processing module; 3. Control module; 4. Alarm module. DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] The utility model embodiment discloses a tower crane fault alarm device.

[0025] Reference Figure 1 , a tower crane fault alarm device, comprising a collection module 1, a data processing module 2, a control module 3, and an alarm module 4;

[0026] The acquisition module 1 is used to collect data of the tower crane, and the collected data of the tower crane includes the upper and lower limits of the tower crane hook height, the front and rear limits of the horizontal movement of the tower crane sports car on the crane arm, the left and right rotation range of the tower crane, the weight of the tower crane hoisting load, and the tower crane lifting torque;

[0027] The data processing module 2 is used to determine whether the tower crane has a fault based on the data collected by the collection module 1. When determining whether the tower crane has a fault, the data processing module 2 compares the collected tower crane data with the preset threshold value to determine whether the tower crane has a fault;

[0028] The control module 3 is used to start different control instructions corresponding to different tower crane faults according to the judgment result of the data processing module 2, and send the control instructions to the voice alarm module 4;

[0029] The alarm module 4 is used to respond to the control command sent by the control module 3. When the voice alarm module 4 receives the control command, the alarm module 4 outputs an alarm signal. The alarm signal is a voice broadcast signal. After the data processing module 2 judges the data of the tower crane, the data with faults is sent to the control module 3. The control module 3 controls the start of the command corresponding to the tower crane data according to the received data, and sends the command to the alarm module 4. After receiving the command, the alarm module 4 starts and outputs an alarm signal to remind the operator to perform maintenance.

[0030] Furthermore, the acquisition module 1 includes a height sensor, an amplitude sensor, a rotation sensor, a weight sensor, and a torque sensor;

[0031] The height sensor is used to detect the upper limit position and the lower limit position of the tower crane hook height;

[0032] The amplitude sensor is used to detect the front limit position and the rear limit position of the tower crane sports car moving horizontally on the lifting arm;

[0033] The slewing sensor is used to detect the left and right slewing range of the tower crane;

[0034] The weight sensor is used to detect the weight of the heavy object hoisted by the tower crane;

[0035] The torque sensor is used to detect the lifting torque of the tower crane.

[0036] When processing the data of the tower crane collected by the acquisition module 1, the data processing module 2 determines whether the upper and lower limits of the tower crane hook height are within the protection range, whether the range of movement of the tower crane sports car on the lifting arm exceeds the front and rear limit protection ranges, whether the rotation of the tower crane exceeds the left and right rotation ranges, whether the weight of the load hoisted by the tower crane is within the specified weight, and whether the lifting torque of the tower crane is within the torque curve range. The above judgments are all based on preset thresholds or ranges for judgment.

[0037] The acquisition module 1 also collects the operation instructions such as lifting, rotation, and amplitude change on the operating table and the inverter operation, fault, and communication signals. The data processing module 2 determines whether the operation instruction is a given working signal, and determines whether the inverter working condition (operation, fault, etc.) signal and communication signal are normal.

[0038] The developed alarm module 4 and control module 3 and the inverter use 485 communication technology. When the safety limit (upper and lower limits, front and rear limits, left and right limits, weight, torque), gear operation command signal, or inverter fails, the alarm module 4 can report the fault and prompt the solution, which can quickly find the fault point, save troubleshooting and maintenance time, and improve efficiency.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
