Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of transport equipment production, and particularly relates to an online moving device and method for a frame of a scissor lift truck. BACKGROUND

[0002] As an important material handling equipment in industrial production, the scissor lift truck is widely used in the fields of logistics and warehousing, ports and wharfs, and factory workshops, and its efficient and flexible operation characteristics play a key role in improving production efficiency and reducing labor costs. With the rapid development of manufacturing industry, the market demand for scissor lift trucks continues to grow, and the production scale and quality requirements are also constantly improving, which makes each link in the production process of the scissor lift truck particularly important. The frame online process is a basic link to ensure the overall performance and production efficiency of the scissor lift truck.

[0003] In the early production process of the scissor lift truck, the frame online process is mainly operated by manual carrying. Manual carrying not only makes the operator bear a huge labor intensity and has extremely low work efficiency, but also has high safety risks and is prone to cause safety accidents. In addition, due to the limitations of manual operation accuracy, it is difficult to ensure the position accuracy and stability of the frame during the online process, which will adversely affect the quality of the subsequent production process, resulting in uneven product quality and difficulty in meeting the increasingly improving production requirements.

[0004] With the development of technology, some enterprises introduce simple hoisting equipment such as manual hoists and small cranes to replace manual operation for frame online work. Although these simple hoisting equipment reduces the labor intensity to a certain extent, it still exposes many problems in actual application. The operation process is relatively complicated, the automation degree is low, and efficient and rapid frame online operation cannot be achieved. The positioning accuracy cannot meet the needs of high-precision production, affecting the precision and stability of production. At the same time, the production efficiency is limited, which is difficult to adapt to the modern production mode of large scale and high efficiency. More importantly, these simple hoisting equipment has poor universality. When facing frames of different sizes and shapes, it is necessary to frequently replace the hoisting tools and adjust the working method, which not only increases the production preparation time, but also greatly increases the production cost, seriously restricting the economy and efficiency of the production of the scissor lift truck.

[0005] In summary, the existing online method of the scissor lift truck frame has the problems of high labor intensity, low efficiency, poor safety, insufficient accuracy, poor universality, and high cost, and an online moving device and method for a frame of a scissor lift truck are urgently needed.
