[0020] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The liquid medicine pump system equipment in LCD panel factories is a device used to precisely control the delivery of liquid medicine. It acts on the infusion catheter through mechanical or electronic means to ensure that the liquid medicine is delivered to the required location in the production process at a uniform speed. The liquid medicine pump system equipment is mainly used in the production process of LCD panels to precisely control the flow and speed of the liquid medicine to ensure that the amount of liquid medicine used in the production process is accurate. It uses electronic control systems and precision flow sensors to achieve high-precision infusion speed control, thereby improving production safety and efficiency. In addition, the liquid medicine pump system can also reduce manual operations, reduce the labor intensity of operators, and improve the automation level of the production line.

[0022] See also Figures 1-4 As shown, this embodiment provides a traction mechanism for loading and unloading cargo, including a vehicle body 100. Considering that the liquid medicine pump system equipment of the liquid crystal panel factory requires regular maintenance, the liquid medicine pump system equipment is usually heavy and bulky. The traditional manual handling method is not only time-consuming and labor-intensive, but also easily causes harm to the operator. Alternatively, some equipment may be used for handling. However, during the handling process, the liquid medicine pump system equipment may tilt or slide due to unstable center of gravity, uneven road conditions or external forces, which will not only damage the equipment but also pose a safety threat to the operator. Therefore, the details are as follows: a handle 102 is installed on the upper surface of the front end of the vehicle body 100, and a traction assembly 200 is installed on the upper surface of the rear end of the vehicle body 100. The traction assembly 200 is used to connect and drag the liquid medicine pump system equipment. Adjustable protective assemblies 300 are symmetrically installed on the upper surface of the vehicle body 100, wherein:

[0023] The protection assembly 300 is used to prevent the liquid medicine pump system equipment from sliding off or tilting from the vehicle body 100 during transportation.

[0024] The improvement of this embodiment is that:

[0025] The design of the traction component 200 enables the vehicle body 100 to stably drag the liquid medicine pump system equipment without causing damage or tilting to it, making it convenient to load and unload and carry the liquid medicine pump system equipment, and solving the problem of traditional manual loading and unloading difficulties; an adjustable protective component 300 is provided, and the height of the protective component 300 can be adjusted according to the size of the liquid medicine pump system equipment, which can better fix the liquid medicine pump system equipment, reduce its shaking and vibration during transportation, and ensure that the equipment will not tilt from the platform during transportation.

[0026] Specifically, the protective component 300 includes a mounting frame 301 and a mating rod 302, and the mounting frame 301 and the mating rod 302 are slidably matched, wherein: a limiting hole is provided on the top side wall of the mounting frame 301, and a locking block 3011 is fitted and locked with the internal thread of the limiting hole, and the top of the locking block 3011 is fitted and locked with the outer wall of the mating rod 302. By adopting a sliding fit between the mating rod 302 and the mounting frame 301, the mating rod 302 can be flexibly moved and adjusted on the mounting frame 301, and can be adjusted according to the size and shape of the liquid pump system equipment to provide the best protection effect. When the mating rod 302 is moved to the appropriate position, the operator can fix it by rotating the locking block 3011, and the top of the locking block 3011 is fitted and locked with the outer wall of the mating rod 302, ensuring that the mating rod 302 will not move accidentally during transportation.

[0027] In order to further improve the stability of the mounting frame 301, a number of support plates 3010 are arranged between the two opposite inner walls of the mounting frame 301, and two adjacent support plates 3010 are arranged in parallel. The parallel arrangement of the two adjacent support plates 3010 helps to disperse the load and reduce stress concentration, thereby improving the strength and stability of the overall structure. The enhanced structural strength and stability help prevent the equipment from tilting or sliding during transportation, thereby protecting the equipment from damage.

[0028] Secondly, the traction assembly 200 includes a traction seat 201 and a steering gear 202. The steering gear 202 is fixed to the upper surface of the traction seat 201 by bolts. A connecting hole 2010 is provided on the upper surface of the end of the traction seat 201. The steering gear 202 is fixed to the upper surface of the traction seat 201 by bolts, ensuring that the steering gear 202 can firmly withstand forces from different directions and maintain its positioning accuracy. The connecting hole 2010 allows connection with the liquid pump system equipment.

[0029] In addition, a number of self-locking universal wheels 101 are installed on the lower surface of the vehicle body 100, and a drive system is installed inside the vehicle body 100. The drive system includes a motor, a battery and a controller. The self-locking universal wheels 101 enable the vehicle body 100 to move easily in different directions, which increases the flexibility of operation. The self-locking universal wheels 101 can be locked when needed to prevent unnecessary movement or sliding, thereby improving the stability and safety during transportation. The motor serves as the power source of the drive system and is powered by a battery to realize the conversion of electrical energy into mechanical energy to drive the vehicle to move. The controller is responsible for receiving the operator's instructions and controlling the operation of the motor to achieve precise speed and direction control.

[0030] When the traction mechanism of the utility model for loading and unloading cargo is used, the user connects the specific part of the liquid medicine pump system equipment (such as the reserved lifting ring or hole) to the vehicle body 100 through the connecting hole 2010 on the traction seat 201, and then places the equipment on the platform of the vehicle body 100. After that, according to the height of the liquid medicine pump system equipment, the mounting frame 301 and the matching rod 302 in the protective component 300 are adjusted, and the threaded fit between the limiting hole and the locking block 3011 is used to adjust to the appropriate position and then lock the matching rod 302 to adapt to the size of the liquid medicine pump system equipment and ensure its Stability, the user holds the handle 102 and uses the flexibility of the self-locking universal wheel 101 to push or pull the vehicle body 100 to move the liquid medicine pump system equipment to the designated position. The hand-pull operation is usually used for short-distance or low-speed movement. In addition to manual operation, the user can also start the electric drive system. The motor starts working and transmits power to the wheel through the transmission device. The self-locking universal wheel 101 starts to rotate under the drive of the motor, thereby pushing the entire device forward. At the same time, the controller can adjust the speed and direction of the motor according to the user's instructions to realize the acceleration, deceleration and steering functions of the equipment.
