[0004] When in use, this utility model can clamp and fix the container to a fixed size, and cannot be adjusted according to the size of the container. Utility Model Content

[0005] The purpose of this invention is to provide a container front-end lifting device to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a container front-end lifting device, comprising a lifting device, the lifting device consisting of an outer frame and an internal support, the internal support being located inside the outer frame, guide mechanisms being installed at both ends of the outer frame, a rotating mechanism being installed around the outer perimeter of the outer frame, a positioning pin being installed at the bottom end of the rotating mechanism, the internal support being installed inside the outer frame via a telescopic mechanism, an uninterruptible power supply being installed in the middle of the upper end of the internal support, a controller being installed at the upper end of the uninterruptible power supply, a wireless transceiver module being installed at the upper end of the controller, and hanging rings being installed around the upper perimeter of the internal support.

[0007] Preferably, the outer frame and the inner support are provided with a corrosion-resistant layer on their outer side, and the corrosion-resistant layer is a chrome-plated layer.

[0008] Preferably, the rotating mechanism consists of a motor and a rotating rod. The motor is installed on the upper part of the outer perimeter of the outer frame, and the rotating rod is installed at the bottom of the motor. The bottom end of the rotating rod is installed on the upper side of the positioning pin.

[0009] Preferably, the guiding mechanism consists of a guide rod and a slide groove. The guide rod is installed in the longitudinal and transverse positions of the outer frame, and the slide groove is set in the longitudinal and transverse positions of the outer frame. The guide rod is slidably installed inside the slide groove.

[0010] Preferably, a limiting plate is provided at one end of the guide rod extending into the slide groove, and the limiting plate is welded to one end of the guide rod.

[0011] The telescopic mechanism consists of a first telescopic rod and a second telescopic rod, which are respectively installed at the horizontal and vertical ends of the internal support.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The telescopic mechanism drives the external frame to adjust its size, enabling the device to adapt to containers of different sizes. The guide mechanism enables precise positioning and movement adjustment to meet the operational needs under different working conditions. 2. During the adjustment of the external frame according to the size of the container, the guide rod and the slide rail work together to play a guiding role. When the external frame needs to be adjusted longitudinally or laterally, the guide rod will slide along the corresponding slide rail to limit the movement direction of the external frame, ensuring that the frame will not deviate or shake during the adjustment process, ensuring the stability and accuracy of the adjustment process, so that the external frame can be accurately adjusted to match the size of the container. 3. During the sliding of the guide rod along the slide groove, the limiting plate plays a limiting role. When the guide rod slides to the limit position of the slide groove, the limiting plate will contact the end of the slide groove to prevent the guide rod from continuing to slide and prevent the guide rod from falling out of the slide groove. This ensures the structural integrity and working reliability of the guiding mechanism and avoids affecting the adjustment function of the external frame and the safe operation of the entire device due to the guide rod falling off. 4. When it is necessary to adjust the size of the external frame to fit containers of different sizes, the controller controls the telescopic mechanism to move. The first telescopic rod moves to extend and retract, causing the width of the lateral part of the external frame to be adjusted; the second telescopic rod moves to extend and retract, causing the length of the longitudinal part of the external frame to be adjusted. Through the coordinated action of the first and second telescopic rods, the size of the external frame in the lateral and longitudinal directions can be adjusted, thereby adapting to the lifting requirements of containers of different specifications.

[0015] 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.

[0016] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a container front lifting device includes a lifting device 1, which consists of an outer frame 3 and an inner support 4. The inner support 4 is located inside the outer frame 3. Guide mechanisms 6 are installed at both ends of the outer frame 3. A rotating mechanism 16 is installed around the outer perimeter of the outer frame 3. A positioning pin 19 is installed at the bottom of the rotating mechanism 16. The inner support 4 is installed inside the outer frame 3 through a telescopic mechanism 5. An uninterruptible power supply 13 is installed in the middle of the upper end of the inner support 4. A controller 14 is installed on the upper end of the uninterruptible power supply 13. A wireless transceiver module 15 is installed on the upper end of the controller 14. Hanging rings 7 are installed around the upper perimeter of the inner support 4.

[0017] The outer frame 3 and the inner support 4 are provided with a corrosion-resistant layer 2, which is a chrome-plated layer. During operation, the outer frame 3 and the inner support 4 will come into contact with various environmental media. As a corrosion-resistant layer 2, the chrome-plated layer can form a dense protective film on the surface of the frame and support, effectively isolating air, moisture and corrosive substances that may be present in the working environment, preventing the frame and support from rusting, extending the service life of the device, and ensuring stable operation even in humid and corrosive working conditions.

[0018] The rotating mechanism 16 consists of a motor 17 and a rotating rod 18. The motor 17 is mounted on the upper part of the outer perimeter of the outer frame 3, and the rotating rod 18 is mounted on the bottom end of the motor 17. The bottom end of the rotating rod 18 is mounted on the upper side of the positioning pin 19. When it is necessary to adjust the angle of the positioning pin 19 to meet the positioning requirements of the container, the controller 14 sends a control signal to the motor 17. The motor 17 starts and outputs torque, which is transmitted to the positioning pin 19 through the rotating rod 18. This causes the positioning pin 19 to rotate around the axis of the rotating rod 18, thereby achieving precise adjustment of the positioning pin 19 at different angles. This ensures that it can accurately engage with the positioning hole of the container or cooperate with the positioning structure of the container, improving the accuracy and efficiency of lifting and positioning.

[0019] The guiding mechanism 6 consists of a guide rod 10 and a slide 11. The guide rod 10 is installed in the longitudinal and transverse positions of the outer frame 3, and the slide 11 is also installed in the longitudinal and transverse positions of the outer frame 3. The guide rod 10 is slidably installed inside the slide 11. During the adjustment of the outer frame 3 according to the size of the container, the guide rod 10 and the slide 11 work together to provide guidance. When the outer frame 3 needs to be adjusted longitudinally or laterally, the guide rod 10 slides along the corresponding slide 11, limiting the direction of movement of the outer frame 3. This ensures that the frame will not shift or shake during the adjustment process, guaranteeing the smoothness and accuracy of the adjustment process, and enabling the outer frame 3 to be accurately adjusted to match the size of the container.

[0020] A limiting plate 12 is provided at one end of the guide rod 10 that extends into the slide groove 11. The limiting plate 12 is welded to one end of the guide rod 10. During the sliding of the guide rod 10 along the slide groove 11, the limiting plate 12 acts as a limit. When the guide rod 10 slides to the limit position of the slide groove 11, the limiting plate 12 will contact the end of the slide groove 11, preventing the guide rod 10 from continuing to slide and preventing the guide rod 10 from detaching from the slide groove 11. This ensures the structural integrity and operational reliability of the guiding mechanism 6 and avoids affecting the adjustment function of the external frame 3 and the safe operation of the entire device due to the guide rod 10 falling off.

[0021] The telescopic mechanism 5 consists of a first telescopic rod 8 and a second telescopic rod 9, which are respectively installed at the horizontal and vertical ends of the internal support 4. When it is necessary to adjust the size of the outer frame 3 to accommodate containers of different sizes, the controller 14 controls the telescopic mechanism 5 to move. The first telescopic rod 8 extends and retracts, causing the horizontal portion of the outer frame 3 to adjust its width; the second telescopic rod 9 extends and retracts, causing the vertical portion of the outer frame 3 to adjust its length. Through the coordinated action of the first telescopic rod 8 and the second telescopic rod 9, the size of the outer frame 3 can be adjusted in both the horizontal and vertical directions, thereby adapting to the lifting requirements of containers of different specifications.

[0022] The working principle and usage process of this utility model are as follows: The outer frame 3 serves as the main support structure of the device. The guide mechanism 6 enables precise positioning and movement adjustment to adapt to different working conditions. The rotating mechanism 16 can drive the positioning pin 19 to rotate at multiple angles, facilitating precise positioning and fixing of the container during hoisting operations. The internal support 4 is connected to the outer frame 3 through the telescopic mechanism 5. When the outer frame 3 needs to be adjusted according to the size of the container, the telescopic mechanism 5 moves to drive the outer frame 3 to adjust its size, enabling the device to adapt to containers of different specifications. The uninterruptible power supply 13 provides continuous power to the electrical components of the entire device, ensuring uninterrupted operation. The controller 14 serves as the core control unit, receiving command signals transmitted by the wireless transceiver module 15 and coordinating the actions of the guide mechanism 6, the rotating mechanism 16, and the telescopic mechanism 5 to achieve automated control of the hoisting operation.

[0023] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
