[0004] When using this invention, the measuring angle cannot be adjusted over a wide range, and it cannot be used normally when the power is off. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent anti-collision component for tower cranes to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tower crane intelligent anti-collision component, including an anti-collision device and a controller; the anti-collision device and the controller are connected via a wireless connection module; the anti-collision device consists of an ultrasonic sensor, a longitudinal rotation mechanism, a transverse rotation mechanism, and a base; a soft metal pad is installed at the bottom of the base; an uninterruptible power supply is installed inside the base; the transverse rotation mechanism is installed on the upper side of the base; the longitudinal rotation mechanism is installed on the upper side of the transverse rotation mechanism; the ultrasonic sensor is installed on the upper side of the longitudinal rotation mechanism; an alarm is installed below one side of the controller; and a running indicator light is installed above one side of the controller.

[0007] Preferably, the longitudinal rotation mechanism consists of a mounting frame and a first power mechanism. The mounting frame is mounted on the upper side of the transverse rotation mechanism, the ultrasonic sensor is rotatably mounted on the upper side of the mounting frame, and one end of the ultrasonic sensor is mounted on the upper side of the first power mechanism through the mounting frame. The first power mechanism is mounted on the upper side of the mounting frame.

[0008] Preferably, the transverse rotation mechanism consists of a housing, a second power mechanism, and a shaft. The housing is mounted on the upper side of the base, the second power mechanism is mounted inside the upper part of the housing, the shaft is mounted on the upper side of the second power mechanism, and the upper end of the shaft is mounted in the middle of the bottom end of the longitudinal rotation mechanism.

[0009] Preferably, both the first power mechanism and the second power mechanism consist of an electric motor and a transmission, with the electric motor mounted on one side of the transmission.

[0010] Preferably, a display is mounted on the upper side of the controller, and control buttons are mounted on the upper side of the controller at a position next to the display.

[0011] Preferably, the wireless connection module consists of a wireless transmitter and a wireless receiver. The wireless transmitter is mounted on the upper side of the controller, and the wireless receiver is mounted on the upper side of the base. The wireless transmitter and the wireless receiver are wirelessly connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. During use, the ultrasonic sensor can be adjusted over a wide range through the longitudinal and lateral adjustment mechanisms, thereby expanding the monitoring range. At the same time, the uninterruptible power supply ensures the normal operation of the anti-collision device in the event of power supply abnormalities.

[0014] 2. During tower crane operation, in order for the ultrasonic sensor to monitor obstacles within a 360-degree range around the tower crane, the lateral rotation mechanism starts to work. The second power mechanism drives the longitudinal rotation mechanism and the ultrasonic sensor installed on it to rotate laterally. In this way, the ultrasonic sensor can perform an all-round scan in the horizontal direction and obtain obstacle information in all directions around the tower crane in real time, providing comprehensive monitoring and protection for the safe operation of the tower crane.

[0015] 3. As the "brain" of the entire intelligent anti-collision system for tower cranes, the controller undertakes the important tasks of data processing and command issuance. When the controller receives distance data collected by the ultrasonic sensors of the anti-collision device through the wireless connection module, it compares and analyzes this data with the preset safety threshold. If the data shows that the distance between the tower crane and the obstacle is close to or less than the safety threshold, the controller will react immediately. On the one hand, it sends control commands to the anti-collision device through the wireless transmitter to adjust the monitoring angle and range of the ultrasonic sensors for more accurate obstacle monitoring. On the other hand, the controller will trigger the alarm to sound an alarm, alerting the operator to potential collision hazards. At the same time, the display on the controller will show key information such as the current distance between the tower crane and the obstacle in real time, allowing the operator to intuitively understand the surrounding environment. The operator can also input operating commands to the controller through the control buttons to adjust the working mode and parameter settings of the entire anti-collision system.

[0016] 4. The wireless connection module acts as a data transmission bridge in the intelligent anti-collision component of the tower crane. During data transmission, the wireless receiver in the anti-collision device receives data such as the distance between the tower crane and surrounding obstacles collected by the ultrasonic sensor. This data is encoded and processed internally by the wireless receiver before being transmitted as wireless signals. The wireless transmitter on the controller receives these wireless signals, decodes them, and restores them to the original data information, which is then transmitted to the controller for analysis. When the controller needs to send a command to the anti-collision device after analyzing the data, the command information is encoded internally and transmitted as a wireless signal through the wireless transmitter. The wireless receiver on the anti-collision device receives the signal, decodes it, and transmits the command to the various actuators of the anti-collision device, such as the longitudinal rotation mechanism and the lateral rotation mechanism, so that they perform the corresponding actions according to the command. This enables the controller to remotely and wirelessly control the anti-collision device, ensuring that the entire anti-collision component can work together and guaranteeing the safe operation of the tower crane.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, a smart anti-collision component for tower cranes includes an anti-collision device 1 and a controller 12. The anti-collision device 1 and the controller 12 are connected by a wireless connection module 11. The anti-collision device 1 consists of an ultrasonic sensor 2, a longitudinal rotation mechanism 5, a transverse rotation mechanism 6, and a base 8. A soft metal pad 9 is installed at the bottom of the base 8, and an uninterruptible power supply 7 is installed inside the base 8. The transverse rotation mechanism 6 is installed on the upper side of the base 8, the longitudinal rotation mechanism 5 is installed on the upper side of the transverse rotation mechanism 6, the ultrasonic sensor 2 is installed on the upper side of the longitudinal rotation mechanism 5, an alarm 16 is installed on the lower side of one side of the controller 12, and a running indicator light 21 is installed on the upper side of one side of the controller 12.

[0025] The longitudinal rotation mechanism 5 consists of a mounting frame 3 and a first power mechanism 4. The mounting frame 3 is installed on the upper side of the transverse rotation mechanism 6. The ultrasonic sensor 2 is rotatably installed on the upper side of the mounting frame 3. One end of the ultrasonic sensor 2 is mounted on the upper side of the first power mechanism 4 through the mounting frame 3. The first power mechanism 4 is installed on the upper side of the mounting frame 3. When the tower crane needs to monitor obstacles at different heights, the first power mechanism 4 is turned on by a switch. The first power mechanism 4 then takes effect, and the adjusted power is transmitted to the ultrasonic sensor 2 through the shaft, causing the ultrasonic sensor 2 to rotate longitudinally on the upper side of the mounting frame 3. This enables all-round monitoring of different height areas, ensuring that the tower crane can detect obstacles that may appear at various heights in a timely manner during operation, whether it is lifting heavy objects upwards or lowering heavy objects downwards.

[0026] The transverse rotation mechanism 6 consists of a housing 20, a second power mechanism 22, and a shaft 19. The housing 20 is mounted on the upper side of the base 8, the second power mechanism 22 is mounted inside the upper part of the housing 20, and the shaft 19 is mounted on the upper side of the second power mechanism 22. The upper end of the shaft 19 is mounted in the middle of the bottom of the longitudinal rotation mechanism 5. During tower crane operation, in order to enable the ultrasonic sensor 2 to monitor obstacles within a 360-degree range around the tower crane, the transverse rotation mechanism 6 starts to work. The second power mechanism 22 drives the longitudinal rotation mechanism 5 and the ultrasonic sensor 2 mounted on it to rotate laterally. In this way, the ultrasonic sensor 2 can perform an all-round scan in the horizontal direction and obtain obstacle information in all directions around the tower crane in real time, providing comprehensive monitoring and protection for the safe operation of the tower crane.

[0027] Both the first power mechanism 4 and the second power mechanism 22 consist of an electric motor 18 and a gearbox 17. The electric motor 18 is installed on one side of the gearbox 17. In the entire intelligent anti-collision assembly of the tower crane, the first power mechanism 4 and the second power mechanism 22 are the core power drive parts. Their working principles are basically the same. After the electric motor 18 is powered on, according to the principle of electromagnetic induction, the internal stator winding generates a rotating magnetic field. The rotor starts to rotate under the action of the rotating magnetic field, converting electrical energy into mechanical energy and outputting rotational power. However, different working scenarios and monitoring needs have different requirements for rotational speed and torque. At this time, the gearbox 17 plays a role. The gearbox 17 adjusts the speed and torque output by the electric motor 18 through gear transmission and other means, increasing or decreasing the torque and decreasing or increasing the speed according to actual needs, thereby providing suitable power for the longitudinal rotation mechanism 5 and the transverse rotation mechanism 6, ensuring that the ultrasonic sensor 2 can perform rotational monitoring in a predetermined manner and speed.

[0028] A display 15 is mounted on the upper side of the controller 12, and control buttons 13 are mounted on the upper side of the controller 12 to one side of the display 15. As the "brain" of the entire tower crane intelligent anti-collision component, the controller 12 undertakes the important tasks of data processing and command issuance. When the controller 12 receives distance data collected by the ultrasonic sensor 2 from the anti-collision device 1 through the wireless connection module 11, it compares and analyzes this data with the preset safety threshold. If the data shows that the distance between the tower crane and the obstacle is close to or less than the safety threshold, the controller 12 will react immediately. On the one hand, it sends control commands to the anti-collision device 1 through the wireless transmitter 10 to adjust the monitoring angle and range of the ultrasonic sensor 2 in order to more accurately monitor the obstacle. On the other hand, the controller 12 will trigger the alarm 16 to sound an alarm, reminding the operator of the potential collision hazard. At the same time, the display 15 on the controller 12 will display key information such as the current distance between the tower crane and the obstacle in real time, so that the operator can intuitively understand the surrounding environment. The operator can also input operation commands to the controller 12 through the control buttons 13 to adjust the working mode and parameter settings of the entire anti-collision component.

[0029] The wireless connection module 11 consists of a wireless transmitter 10 and a wireless receiver 14. The wireless transmitter 10 is mounted on the upper side of the controller 12, and the wireless receiver 14 is mounted on the upper side of the base 8. The wireless transmitter 10 and the wireless receiver 14 are wirelessly connected. The wireless connection module 11 acts as a data transmission bridge in the intelligent anti-collision assembly for tower cranes. During data transmission, the wireless receiver 14 in the anti-collision device 1 receives data information such as the distance between the tower crane and surrounding obstacles collected by the ultrasonic sensor 2. This data is encoded and processed inside the wireless receiver 14 and then transmitted in the form of wireless signals. The wireless transmitter 10 on the controller 12 receives these wireless signals. Afterwards, the signal is decoded and processed to restore it to the original data information, which is then transmitted to the controller 12 for analysis and processing. When the controller 12 needs to send a command to the anti-collision device 1 after analyzing the data, the command information is encoded inside the controller 12 and sent out in the form of a wireless signal through the wireless transmitter 10. After receiving the signal, the wireless receiver 14 on the anti-collision device 1 decodes it and transmits the command to each actuator of the anti-collision device 1, such as the longitudinal rotation mechanism 5 and the transverse rotation mechanism 6, so that they can perform corresponding actions according to the command. This enables the controller 12 to remotely control the anti-collision device 1, ensuring that the entire anti-collision component can work together and ensuring the safe operation of the tower crane.

[0030] The working principle and usage process of this utility model are as follows: During operation, the ultrasonic sensor 2 in the anti-collision device 1 is responsible for real-time monitoring of the environment around the tower crane. When the tower crane is in operation, the ultrasonic sensor 2 continuously emits ultrasonic signals to all directions and receives the reflected signals. By calculating the time difference between signal transmission and reception, combined with the speed of ultrasonic wave propagation in the air, the distance information between the tower crane and surrounding obstacles can be accurately calculated. This distance data is transmitted to the controller 12 through the wireless receiver 14 in the wireless connection module 11. After receiving the data, the controller 12 analyzes and processes it. If the detected distance is less than the preset safety threshold, the controller 12 will send a command to the anti-collision device 1 through the wireless transmitter 10, and at the same time trigger the alarm 16 to sound an alarm, reminding the operator to pay attention to potential dangers. The operation indicator 21 will also light up according to different operating states, indicating that the anti-collision device 1 is working.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
