The upper end of the lifting frame is equipped with a lifting frame for lifting and lowering the container by means of a hydraulic telescopic rod. The inner side of the lifting frame is equipped with a pulley bracket with an L-shaped structure and a pulley block at one end.

[0007] On both sides of one side of the lifting frame and outside the hydraulic pump, there are fixed frames with semi-circular corners. The upper end of the fixed frame is longitudinally provided with a pulley that cooperates with the pulley in the pulley bracket and is composed of two pulley bodies. On one side of the base, there is a clamping frame for fixing the container during loading and unloading. The clamping frame has a fixing plate with a safety lock installation port on one side of the container fixing surface.

[0008] Preferably, the hydraulic telescopic rod is vertically fixed to the inner side of the lifting frame, and the top of the hydraulic telescopic rod is fixed to the middle of the lower end face of the lifting frame.

The other end of the safety rope passes through a small pulley on the upper end of the pulley bracket and the upper end of the lifting frame from the side of the auxiliary wheel. One end of the safety rope passing through the small pulley is connected to a small pulley on the side of the crossbar of the fixed frame, which can provide additional protection and prevent the container from accidentally falling off.

[0012] Preferably, the base has mounting plates on both sides of the bottom front end, and each mounting plate has a caster A at the bottom. One side of the caster A has a threaded support screw for stable support of the base. The other side of the base has a triangular wheel with three support points in the middle.

[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a technical solution: an electric container wheel, comprising:

[0023] The base 1 provides an installation platform for other components, ensuring the overall stability of the equipment. Its robust materials and optimized dimensions allow it to withstand the weight of the container and various forces generated during loading and unloading, guaranteeing normal operation under different working conditions. A hydraulic pump 2, used for hydraulic lifting control of the container, is located on one side of the base 1. As the power source for the hydraulic lifting system, it precisely controls the delivery volume and pressure of the hydraulic oil, achieving smooth and accurate hydraulic lifting control of the container. Compared to other power sources, hydraulic drive offers advantages such as high output force, smooth operation, and fast response, effectively improving the efficiency and safety of container loading and unloading.

[0024] A lifting frame 11 is provided on one side of the hydraulic pump 2 to support and lift the container during loading and unloading. During container loading and unloading, it provides support and guidance for the lifting frame 4. Its robust structure can withstand the weight of the lifting frame 4 and the container, ensuring the stability of the lifting frame during lifting, preventing swaying and deviation, and ensuring safe loading and unloading operations. The upper end of the lifting frame 11 is hydraulically raised and lowered via a hydraulic telescopic rod 10 for lifting and lowering the container. The hydraulic telescopic rod 10 extends and retracts through hydraulic oil, providing direct power for the lifting of the lifting frame 4. Its vertical fixation ensures that the lifting frame 4 is evenly stressed during lifting, effectively preventing tilting, ensuring the stability of the container during lifting, and reducing the risk of cargo damage. The lifting frame 4 directly undertakes the task of lifting and lowering the container. Its robust structural design can withstand the weight of the container and provides installation space for the pulley bracket 5, working in conjunction with other components to complete the container loading and unloading operations.

[0025] The inner side of the lifting frame 4 is equipped with an L-shaped pulley bracket 5, one end of which has a pulley block. When lifting containers, the pulley block at one end significantly reduces the pulling force required for lifting by changing the direction of the force and utilizing the principle of saving effort, making the lifting process easier and more efficient. At the same time, its cooperation with other pulleys can optimize the mechanical structure of the equipment during operation and reduce energy loss.

[0026] On both sides of one side of the lifting frame 11, and outside the hydraulic pump 2, there are fixed frames 8 with semi-circular corners. The semi-circular corner design effectively avoids collisions and injuries to personnel or other objects during operation, and also provides installation support for the pulleys 9. These pulleys cooperate with the pulleys in the pulley bracket 5 to optimize force transmission during lifting, ensuring smooth lifting operations. The upper end of the fixed frame 8 has a longitudinally mounted pulley 9, composed of two pulley bodies, which cooperate with the pulleys in the pulley bracket 5. This changes the direction of the wire rope 16, further optimizing the force transmission path, and playing a role in saving effort and guiding during lifting, improving the efficiency and stability of the lifting operation.

[0027] A clamping frame 6 for securing containers during loading and unloading is provided on one side of the base 1. One end of the frame has a horizontally extending hanging pin 15. A container lock 17 is installed at the center of the bottom of the container side for initial securing the container's bottom. A stable tension structure is formed by connecting the clamping frame 6 to the pulley bracket 5's labor-saving wheel 12 and the fixing frame 8's pulley 9 via a steel wire rope 16. A fixing plate 7 with a safety locking port is provided on the side of the clamping frame 6 facing the container, providing an installation position for the safety locking device and further enhancing the security of the container's fixation. Its placement on the side of the clamping frame 6 facing the container effectively disperses the pressure generated during container fixing, improving the reliability of the fixation.

[0028] The hydraulic telescopic rod 10 is vertically fixed to the inner side of the lifting frame 11, and the top of the hydraulic telescopic rod 10 is fixed to the middle of the lower end face of the lifting frame 4. The hydraulic pump 2 is connected to the hydraulic telescopic rod 10 through a hydraulic oil pipe.

[0029] The pulley system includes two sets of labor-saving wheels 12. Each set of labor-saving wheels 12 consists of two vertically arranged wheel bodies, and the two sets of labor-saving wheels 12 are installed side by side on the inner side of one end of the pulley bracket 5. Through a special structural design, the direction of force is changed during the lifting process, and the lever principle is used to achieve a labor-saving effect, which greatly reduces the pulling force required to lift the container, reduces energy consumption, and improves the efficiency of lifting operations. The pulleys are installed on the inner side of one end of the pulley bracket 5 and are in contact with the bypassed wire rope 16. The wire rope is connected to the hanging pin 15 on the clamping frame 6 to realize the transmission of force and the labor-saving effect.

[0030] An auxiliary wheel 13 is provided at the other end of the pulley bracket 5. During equipment operation, the auxiliary pulley bracket 5 moves smoothly, reducing the friction between the pulley bracket and other components, ensuring the smoothness of the entire lifting and moving process, and helping to balance the force on the pulley bracket during operation. Small pulleys 14 are provided on the upper end of the pulley bracket 5, the upper end face of the lifting frame 4, and the inner side of the upper crossbar of the fixed frame 8. They are respectively located on the upper end of the pulley bracket 5, the upper end face of the lifting frame 4, and the inner side of the upper crossbar of the fixed frame 8. During equipment operation, they reduce the friction between components, making the wire rope, safety rope, etc. move more smoothly, reducing energy loss, optimizing the mechanical structure of the equipment, improving the stability of equipment operation, and contacting and cooperating with the wire rope 16, safety rope 19, etc. to guide their movement direction.

[0031] A hanging pin 15 is horizontally inserted through one end of the clamping frame 6, providing a connection point for the wire rope 16. This allows the wire rope to be wound and connected around the pin, thus creating a stable tension structure. This connects the clamping frame to the pulley block, enabling effective fixing and lifting of the container. Both ends of the hanging pin 15 extend to the outside of both ends of the clamping frame 6, and two wire ropes 16 are connected to both ends of the hanging pin 15. These wire ropes serve as a force transmission medium, connecting the clamping frame 6 to the pulley block. By bypassing the force-saving wheel 12 and pulley 9, the force-saving and guiding effect of the pulley block is utilized to achieve the lifting and fixing of the container. Its high-strength material can withstand greater tensile force, ensuring safety during the lifting process. Each steel wire rope 16 passes around each set of labor-saving wheels 12 and pulleys 9 and connects to the middle section of the hanging pin shaft 15. A container lock head 17 is provided at the center of the bottom end of the side of the clamping frame 6 that fixes the container. It is used to initially fix the bottom of the container, prevent the bottom of the container from sliding during the handling process, provide basic support for the entire fixing structure, and enhance the stability of the container fixing.

[0032] A safety wheel 18 is provided on one side of the upper end of the clamping frame 6, and a safety rope 19 is connected to the safety wheel 18. The safety rope 19 is installed on one side of the upper end of the clamping frame 6 and connected to the upper end of the clamping frame 6. In an emergency, the safety rope can change direction through the safety wheel, providing additional safety for the container, preventing accidental detachment, and improving operational safety. The safety rope 19 is connected to the safety wheel 18 and passes sequentially through one side of the auxiliary wheel 13, the upper end of the pulley bracket 5, the upper surface of the lifting frame 4, and the small pulley 14 on one side of the crossbar of the fixed frame 8, forming an additional safety protection structure. This structure can quickly function in case of equipment malfunction, preventing the container from falling and ensuring the safety of personnel and goods. The other end of the safety rope 19 passes through the small pulley 14 on the upper end of the pulley bracket 5 and the upper surface of the lifting frame 4 from one side of the auxiliary wheel 13, and the end of the safety rope 19 passing through the small pulley 14 is connected to the small pulley 14 on one side of the crossbar of the fixed frame 8.

[0033] Mounting plates 20 are located on both sides of the bottom front end of the base 1, providing a mounting platform for the casters A21. Their reasonable structural design ensures stable installation and normal operation of the casters, enabling the equipment to flexibly turn and adapt to different work site requirements. Casters A21 are mounted on the bottom of each mounting plate 20, allowing the equipment to flexibly turn on the work site, facilitating position adjustments and improving work efficiency. Their excellent rolling performance and turning flexibility adapt to different ground conditions, ensuring smooth equipment movement. A support screw 22, providing stable support to the base, is threaded through one side of the caster A21. When stable support is needed, rotating the support screw causes the lower support plate to contact the ground, providing additional support force and enhancing stability during operation. This prevents the equipment from swaying or shifting due to uneven force during container loading and unloading. A triangular wheel 23 with three support points is located in the middle of the bottom of the other side of the base 1. During equipment movement, it works in conjunction with the casters A21 to ensure smooth movement under different ground conditions. During operation, the triangular wheel structure can effectively distribute the pressure on the equipment and improve the overall stability of the equipment.

[0034] Specifically, during operation, when the lifting frame 4 rises to lift the container, the two sets of labor-saving wheels 12 on the inner side of one end of the pulley bracket 5 come into play. Each set of labor-saving wheels 12 consists of two vertically arranged wheel bodies, which change the direction of the force and achieve a labor-saving effect. The wire rope 16 passes over the labor-saving wheels 12 and the pulley 9 at the upper end of the fixed frame 8, and connects to the hanging pin 15 on the clamping frame 6. During lifting, pulling the wire rope 16, through the cooperation of the pulley group, reduces the pulling force required to lift the container, making the lifting process easier. At the same time, the auxiliary wheel 13 at the other end of the pulley bracket 5, the upper end of the pulley bracket 5, the upper surface of the lifting frame 4, and the small pulley 14 on one side of the crossbar of the fixed frame 8 reduce the friction between components during equipment operation, ensuring smooth operation of the entire lifting and moving process.

[0035] When the lifting frame 4 rises to lift the container, the two sets of labor-saving wheels 12 on the inner side of one end of the pulley bracket 5 come into play. Each set of labor-saving wheels 12 consists of two vertically arranged wheel bodies, which change the direction of the force and achieve a labor-saving effect. The wire rope 16 passes over the labor-saving wheels 12 and the pulley 9 at the upper end of the fixed frame 8, and connects to the hanging pin 15 on the clamping frame 6. During lifting, pulling the wire rope 16, through the cooperation of the pulley group, reduces the pulling force required to lift the container, making the lifting process easier. At the same time, the auxiliary wheel 13 at the other end of the pulley bracket 5, the upper end of the pulley bracket 5, the upper surface of the lifting frame 4, and the small pulley 14 on one side of the crossbar of the fixed frame 8 reduce the friction between components during equipment operation, ensuring smooth operation of the entire lifting and moving process.

[0036] The container is placed in the clamping frame 6, and the container lock 17 at the center of the bottom of the clamping frame 6 can initially secure the bottom of the container. Simultaneously, the two steel wire ropes 16 connected to the lifting pin 15 at one end of the clamping frame 6, after passing over the labor-saving wheel 12 and pulley 9, are connected in the opposite direction to the middle section of the lifting pin 15, forming a stable traction structure that further secures the container from above and the side, preventing it from swaying during loading and unloading. Furthermore, the safety rope 19 connected to the safety wheel 18 on one side of the upper end of the clamping frame 6 passes sequentially through the small pulleys 14 on one side of the auxiliary wheel 13, the upper end of the pulley bracket 5, the upper surface of the lifting frame 4, and the side of the crossbar of the fixing frame 8, forming an additional safety protection structure that can prevent the container from accidentally detaching in an emergency.

[0037] The mounting plates 20 on both sides of the front bottom of the base 1 are equipped with casters A21, allowing the equipment to turn flexibly and adapt to different working environments. When stabilization is required, rotating the threaded support screw 22 on one side of the caster A21 causes the support plate at the lower end of the support screw to contact the ground, providing additional support and enhancing stability. The triangular wheel 23 at the center of the bottom on the other side of the base 1 works in conjunction with the casters A21 during equipment movement to ensure smooth movement on different ground conditions. Furthermore, the three-point support structure of the triangular wheel also contributes to improved overall stability during operation.

Although the present 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.
