[0031] It should be noted that the transfer limiting trolley in this embodiment can adapt to energy storage converters of different sizes and shapes, has good versatility, and can be used for the transfer of energy storage converters of different models.

[0032] On the basis of the above embodiment, the movable frame 10 includes a support portion 11 and a grip portion 12. The support portion 11 is arranged on the ground, the grip portion 12 is vertically arranged at one end of the top surface of the support portion 11, and the limit assembly 30 is arranged on the inner side of the grip portion 12; the design of the grip portion 12 enables the operator to hold the trolley more comfortably and stably to perform the transfer operation, thereby improving the convenience and humanization of the operation; the grip portion 12 is vertically arranged at one end of the top surface of the support portion 11, and the limit assembly 30 is arranged on the inner side of the grip portion 12. Such a layout can save space, making the top of the movable frame 10 more open, which is convenient for loading and unloading the energy storage converter.

[0033] On the basis of the above embodiment, the support part 11 includes a base frame 111 and universal wheels 112. The base frame 111 includes an upper top frame 111a and a lower bottom frame 111b of the same shape. The upper top frame 111a and the lower bottom frame 111b are arranged parallel to each other, and the four corners are vertically fixedly connected by auxiliary support rods 111c. There are four universal wheels 112, which are respectively fixedly connected to the four corners of the lower bottom frame 111b on one side away from the auxiliary support rods 111c; the vertical fixed connection structure between the upper top frame 111a, the lower bottom frame 111b and the auxiliary support rods 111c enhances the stability of the entire trolley. The setting of the universal wheels 112 allows the transfer limit trolley to rotate freely, realize movement in different directions, and improve the flexibility and efficiency of transfer.

[0034] On the basis of the above embodiment, the gripping portion 12 includes a connecting rod 121 and two extension rods 122 arranged parallel to each other, one end of the extension rod 122 is vertically fixed on the top surface of the upper frame 111a, and the two ends of the connecting rod 121 are respectively vertically fixedly connected to the other end portions of the two extension rods 122, and a handle 123 is fixedly connected to the side of the connecting rod 121 away from the upper frame 111a, and the handle 123 and the connecting rod 121 are arranged parallel to each other; a stable support structure is formed by the connecting rod 121 and the extension rod 122, which increases the stability of the gripping portion 12, so that the operator can control the moving direction and speed of the trolley more steadily and comfortably during the transportation process, thereby improving the operating comfort.

[0035] On the basis of the above embodiments, a grip 34 is provided on the top surface of the end of the blocking block 31 facing away from the clamping block 33. The transfer point between the blocking block 31 and the extension rod 122 is located between the grip 34 and the clamping block 33. The provision of the grip 34 enables the operator to quickly adjust the relative position and angle of the blocking block 31, improving the adjustment efficiency during the transfer process. The transfer point between the blocking block 31 and the extension rod 122 is located between the grip 34 and the clamping block 33. By means of the end where the grip 34 is located, the limiting relationship between the clamping block 33 and the energy storage converter can be controlled, ensuring the stability of the energy storage converter during the transfer process, enhancing the stability and durability of the structure, and making the transfer work more efficient and safe.

[0036] On the basis of the above embodiments, an upper limit post 35 and a lower limit post 36 are respectively provided on both sides in the width direction of the clamping block 33. The upper limit post 35 is close to the side where the grip 34 is located and is spaced from the top surface of the clamping block 33. The lower limit post 36 is provided close to the clamping block 33 and is in contact with the bottom surface of the clamping block 33. The provision of the upper and lower limit posts 36 provides additional positioning points. Before transferring the energy storage converter, the blocking block 31 can be rotated through the grip 34 so that the top surface of the blocking block 31 rotates to be in contact with the upper limit post 35, thereby opening the blocking block 31. After the energy storage converter is placed, the grip 34 is released, and the blocking block 31 rotates reversely under the action of its own weight at one end of the clamping block 33 and returns to the initial position. The lower limit post 36 defines the initial position, enabling the clamping block 33 to form a limiting effect on the energy storage converter, ensuring that the energy storage converter can be accurately fixed on the trolley during the transfer process and reducing the risk of damage caused by displacement or vibration.

[0037] On the basis of the above embodiments, a circular arc-shaped guiding surface is formed on the side of the clamping block 33 facing the guiding frame 20. The circular arc-shaped guiding surface can reduce the friction between the clamping block 33 and the guiding frame 20 or the energy storage converter, reduce the wear and impact caused by contact and movement during the transfer process, extend the service life, and improve the durability of the entire transfer trolley.

[0038] On the basis of the above embodiments, the limiting component 30 further includes an adapter block 37. The adapter block 37 is fixedly connected to the side surface of the extension rod 122, and at least one pin hole 37a is provided on the adapter block 37. The locking pin 32 is inserted into the pin hole 37a. The pin hole 37a provided on the adapter block 37 allows the locking pin 32 to be inserted at different positions, providing multiple fixing options, making the adjustment of the limiting component 30 more flexible, and also allowing the limiting component 30 to adapt to energy storage converters of different sizes, providing greater adaptability and flexibility. By using the cooperation of the locking pin 32 and the pin hole 37a, it can be ensured that the limiting component 30 is firmly locked after being adjusted to the appropriate position, preventing accidental sliding or movement during the transfer process and improving the safety of the operation.

[0039] Based on the above embodiments, the guiding frame body 20 further includes two parallel channel steels 22. One side of the channel steel 22 is bent and fixedly connected to the movable frame body 10. A number of rollers 21 are arranged between the two channel steels 22. A number of assembly holes 22a are arranged in pairs along the length direction of the two channel steels 22. The two ends of the roller 21 are respectively inserted into the assembly holes 22a on both sides. The use of the channel steel 22 provides a firm support structure, making the guiding frame body 20 more stable and capable of bearing greater weight and pressure. The design of bending one side of the channel steel 22 and fixedly connecting it to the movable frame body 10 simplifies the installation process and makes the assembly of the guiding frame body 20 more convenient and fast. The assembly holes 22a arranged in pairs along the length direction of the two channel steels 22 provide accurate positioning points for the rollers 21, ensuring that the rollers 21 are evenly distributed. Under the continuous rolling contact surface of the rollers 21, the energy storage converter can be easily transferred from the transfer cart to the next assembly process, improving the guiding effect.

[0040] Based on the above embodiments, a guiding strip 23 is further arranged on the inner side surface of each channel steel 22. The outer shaft surfaces at both ends of the roller 21 are located between the guiding strip 23 and the movable frame body 10. The arrangement of the guiding strip 23 provides an additional guiding surface to form auxiliary positioning, making the roller 21 more stable during operation, reducing deviation, and improving the accuracy of guiding the energy storage converter from the roller 21 to the next process.
