[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0023] See also Figures 1 to 5In the utility model, the multifunctional intelligent gantry crane includes a crane body 1, an electric hoist 2 and a hook 3. The electric hoist 2 is slidably installed on the crane body 1. The hook 3 is connected to the bottom of the electric hoist 2 through a cable. Two support seats 4 are arranged at the bottom of the crane body 1. A mounting seat 5 is slidably connected to the inner wall of the support seat 4. The mounting seat 5 is fixedly connected to the bottom of the crane body 1. Two expansion grooves 6 are provided on the inner wall of the support seat 4. A tooth plate 7 is fixedly connected to the inner bottom wall of the expansion groove 6. The left and right sides of the mounting seat 5 are slidably connected to magnetic seats 8. The magnetic seats 8 are fixedly connected to the bottom of the crane body 1. The bottom of the seat 8 is meshed with the tooth plate 7, an electromagnetic plate 9 is fixedly installed on the inner top wall of the expansion slot 6, and the electromagnetic plate 9 is magnetically connected to the magnetic seat 8. Two mounting slots 10 are provided on the inner bottom wall of the support seat 4, and an expansion airbag 11 is installed on the inner bottom wall of the mounting slot 10. The two expansion airbags 11 are respectively located on the front and back of the mounting seat 5. A processor 12, a wind sensor 13 and a signal transmission module 14 are installed on the crane body 1, and a monitoring component 15 is provided on the hook 3. The monitoring component 15, the wind sensor 13 and the signal transmission module 14 are all connected to the processor 12 signal.

[0024] The monitoring component 15 includes a gravity seat 1501, which is hinged on the front of the hook 3. A pressure sensor 1502 is installed on the gravity seat 1501, and the pressure sensor 1502 is connected to the processor 12 signal. Two limit plates 1503 are fixedly connected to the front of the hook 3, and the two limit plates 1503 are located on the left and right sides of the gravity seat 1501.

[0025] A buzzer 17 is installed on the crane body 1 , and the buzzer 17 is signal-connected to the processor 12 .

[0026] The support seat 4 is connected to the ground or the installation area so that the mounting seat 5 is inside the support seat 4. The crane body 1 is in a vertical state. The cargo can be hoisted by retracting and releasing the hook 3 through the cable. The electric hoist 2 can drive the hook 3 to move and transport the cargo. During the operation of the crane body 1, the wind sensor 13 will monitor the wind speed in the area where the crane body 1 is located and transmit the signal to the processor 12. The processor 12 analyzes the value and transmits the value through the signal transmission module 14. When the wind speed exceeds the set value, the processor 12 will control the buzzer 17 to work. The buzzer 17 sounds to warn nearby personnel. The user can avoid hoisting the cargo and retract the hook 3. If the wind speed is too high and poses a threat to the crane body 1, the user can inflate the inflatable airbag 11 so that the inflatable airbag 11 expands and protrudes from the inside of the mounting groove 10 to contact the mounting seat 5. At this time, the user changes the current direction of the electromagnetic plate 9 so that the electromagnetic plate 9 generates a magnetic field opposite to the magnetic seat 8. The magnetic seat 8 begins to move upward under the magnetic effect, thereby contacting the bottom. When the gear plate 7 of the support seat 4 is separated, the mounting seat 5 can be displaced inside the support seat 4. When the lateral wind with a large force-bearing area blows, the mounting seat 5 squeezes the inflated airbag 11 to achieve buffering. In actual use, if the position of the crane body 1 needs to be adjusted after the support seat 4 is installed, the user can also change the current direction of the electromagnetic plate 9 to make the magnetic seat 8 move up, and the mounting seat 5 loses the restriction, and the mounting seat 5 can be slid inside the support seat 4 to change the position of the crane body 1 for fine adjustment. After the adjustment, the user changes the current direction of the electromagnetic plate 9 to make the magnetic seat 8 move downward to complete the engagement with the gear plate 7, and the mounting seat 5 can be limited. During the operation of the hook 3, if the cable swings or the hook 3 tilts, the gravity seat 1501, which is kept in a vertical state by gravity, will contact the limit plate 1503 on the side, and the pressure sensor 1502 will trigger to generate a value. After the processor 12 receives it, it is remotely transmitted through the signal transmission module 14. The crane operator can stop using the crane body 1 for inspection and inspection to prevent subsequent safety accidents.

[0027] In the utility model, a slidable mounting seat 5 is provided inside the supporting seat 4, so that the position of the crane body 1 can be fine-tuned after the supporting seat 4 is installed, thereby improving practicality, and the expansion airbag 11 provided inside the supporting seat 4 can buffer the mounting seat 5, avoiding shaking caused by the influence of wind force on the large front and rear front force-bearing areas. When the wind force value monitoring exceeds the set value, an alarm will be automatically triggered, and the shaking range and tilt angle of the hook 3 can be intelligently monitored in conjunction with the monitoring component 15, thereby realizing intelligent control of the gantry crane.

[0028] See also Figure 1 and 3, wherein: an additional weight block 16 is fixedly connected to the gravity seat 1501, and the additional weight block 16 is made of metal material.

[0029] In the present invention, the additional weight block 16 made of metal material can increase the weight of the bottom part of the gravity seat 1501, thereby maintaining the stability of the gravity seat 1501 and preventing the gravity seat 1501 from being excessively affected by external factors and causing the pressure sensor 1502 to be accidentally touched.

[0030] See also Figure 1 and 2 , wherein: guide grooves 18 are provided on both the left and right sides of the mounting seat 5 , and the magnetic seat 8 is slidably connected to the inner wall of the guide groove 18 .

[0031] In the present invention, the setting of the guide groove 18 can limit the magnetic base 8, so that the magnetic base 8 is always located on the mounting base 5 and maintains stable movement in the vertical direction.

[0032] See also Figure 1 , 2 4, wherein: evenly distributed running wheels 19 are installed at the bottom of the mounting seat 5, and the bottom of the running wheels 19 contacts the inner bottom wall of the supporting seat 4.

[0033] In the present invention, the arrangement of the running wheels 19 can support the mounting seat 5 , and the rotation of the running wheels 19 when the mounting seat 5 moves can reduce friction and reduce the resistance generated by the moving mounting seat 5 .

[0034] The above is a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and its improved conception of the utility model, which should be included in the protection scope of the utility model.
