[0002] The technical field related to by the utility model, a tipping car unloading machine is a device for quickly unloading bulk materials on trains and trucks, and is widely used in ports, mines and large industrial facilities. It directly transfers the goods on the vehicle to the conveyor belt or the storage yard by tilting and dumping the goods on the vehicle, greatly saving time and human resources. The tipping car unloading machine has high unloading capacity and can quickly process large-capacity materials such as coal, ore and grain. In addition, modern tipping car unloading machines are usually equipped with an automatic control system to ensure precise operation and reduce human intervention. At the same time, a variety of safety measures are added to the design, such as anti-tipping devices and emergency stop buttons, to ensure operation safety. The equipment is made of high-strength materials and can withstand frequent operation and harsh environments. The modular design also facilitates maintenance and component replacement, improving durability. In operations that require frequent and rapid unloading of large quantities of bulk materials, the tipping car unloading machine is particularly important.

[0003] The vehicle body locking function of the tipping car unloading machine is of great significance in the unloading operation. First of all, it greatly improves safety, prevents the vehicle from accidentally moving or slipping during the tilting process, and ensures the safety of operators and equipment. Secondly, the locking function ensures the stability of the vehicle during the unloading process, avoids rollover or overturning accidents caused by heavy loads or uneven loads, and improves the stability of the unloading operation. In addition, by locking the vehicle position, the car unloading machine can more precisely control the tilting angle and unloading speed, ensure that the materials are accurately transferred to the target area, such as the conveyor belt or the storage pile, reduce material waste and ground pollution. Finally, the vehicle body locking function can shorten the car unloading preparation time, enable the system to perform continuous operations more quickly, and thus improve the overall operation efficiency. Especially in ports and industrial facilities that require high-frequency loading and unloading, this function is particularly crucial.
