[0018] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0019] [Example 1]

[0020] A tool cart for assisting in the installation of liquid nitrogen, such as Figure 1 , including a vehicle body 1, a lifting component 2, a universal ball shaft 3 and a liquid nitrogen tank support component 4. The vehicle body 1 is equipped with moving wheels 11 and a handle 12. The lifting component 2 is connected to the vehicle body 1. The liquid nitrogen tank support component 4 is connected to the lifting component 2 through the universal ball shaft 3. The liquid nitrogen tank support component 4 is used to place the liquid nitrogen tank. The height of the liquid nitrogen tank support component 4 can be adjusted by adjusting the height of the lifting component 2.

[0021] It should be noted that the universal ball joint 3 can also be replaced by a rotating shaft.

[0022] The vehicle body 1 can be in the form of a flatbed truck. In other embodiments, it can also be in the form of a cart with a frame. A number of movable wheels 11 are installed on the vehicle body 1 according to the size of the vehicle body. The movable wheels 11 are preferably universal wheels with brake components.

[0023] The lifting component 2 can be a pneumatic cylinder, a hydraulic cylinder or an electric cylinder. The pneumatic cylinder or the electric cylinder can be connected to the gas source or the power source when it reaches the nitrogen adding position. In this embodiment, the lifting component 2 is a hydraulic cylinder, such as a hydraulic jack.

[0024] The liquid nitrogen tank support assembly 4 is provided in one or several groups, or one liquid nitrogen tank support assembly 4 has one or more liquid nitrogen tank placement spaces, which are provided according to the transfer volume requirements.

[0025] In this embodiment, Figure 1 The liquid nitrogen tank support assembly 4 is a semi-cylindrical shell or a cylindrical shell. When a cylindrical shell is used, there is a cylindrical space therein, which can completely place the liquid nitrogen tank; when a semi-cylindrical shell is used, there is a U-shaped accommodating space therein, and a through hole for the pipeline to pass through can be further provided on the shell. The accommodating space can also be set to a V-shaped cross-section, which can stably support liquid nitrogen tanks of different sizes.

[0026] Before liquid nitrogen is installed, the liquid nitrogen tank 5 filled with liquid nitrogen is replaced with a lid with a tube, the lifting assembly 2 is lowered to a suitable height, so that the staff can put the liquid nitrogen tank 5 into the liquid nitrogen tank support assembly 4. After placement is completed, the lifting assembly 2 can be adjusted to a suitable height before transportation, or the liquid nitrogen tank 5 can be adjusted to a suitable height after being transported to the installation position. Preferably, the height is lowered during transfer to ensure stability by lowering the center of gravity. The staff pushes the car body 1 by the handle 12 and transports it to the empty liquid nitrogen tank. The tube is inserted into the empty liquid nitrogen tank, and the direction and angle of the liquid nitrogen tank are adjusted by the universal ball shaft 3 (the universal ball can flip the direction of the liquid nitrogen tank at will). Next, the liquid nitrogen is installed. After adding liquid nitrogen, the empty liquid nitrogen tank is directly removed.

[0027] Optionally, support legs can be installed on both sides of the vehicle body. When liquid nitrogen is added, the support legs are rotated open or installed to support both sides of the vehicle body to ensure stability.

[0028] Example 2, based on Example 1, Figure 2 The vehicle body 1 is equipped with a stabilizing support member 13 to assist in securing the liquid nitrogen tank support assembly 4. This member is used to stabilize the liquid nitrogen tank support assembly 4 during transfer, preventing significant rotation of the liquid nitrogen tank support assembly 4 and causing the vehicle body to become unbalanced. The stabilizing support member 13 can be a rod or chain, with one end connected to the vehicle body and the other end connected to a connection point 41 on the liquid nitrogen tank support assembly 4 via a hook or other means.

[0029] Example 3: Based on Example 1 or 2, one or several groups of lifting component 2 installation positions are provided on the vehicle body 1. Specifically, the lifting component 2 has a fixed plate at the bottom, and two or four bolt holes are provided on the fixed plate. Each installation position on the vehicle body 1 is provided with a corresponding bolt hole. 1 to 3 lifting components 2 can be installed as needed, so that 1 to 3 liquid nitrogen tanks can be transported at a time.

[0030] Furthermore, if Figure 3 A slide rail 14 is provided on the vehicle body 1, and several groups of lifting components 2 are arranged along the slide rail 14. The fixing plate of the lifting component 2 is connected to the slide rail 14 and can be moved to different installation positions along the slide rail 14. When two lifting components 2 and a liquid nitrogen tank supporting component 4 are installed on the vehicle body, but only one liquid nitrogen tank is transported, the lifting component 2 supporting the liquid nitrogen tank can be moved to the installation position in the center position for fixing to ensure stability during transfer.

[0031] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations and modifications may be made to the embodiments of the present invention without departing from the principles described.
