Description

Technical Field

[0001] The invention belongs to the technical field of mechatronic control, and in particular relates to a pressure-yielding electric support for coal mines. Background Art

[0002] With the gradual deepening and development of the field of industrial automation, the hydraulic cylinders used in traditional coal mine supports have been gradually replaced by electric cylinders. However, this technology is not yet mature and cannot achieve the complete electrification of coal mine supports. Therefore, there are still problems such as environmental pollution caused by emulsion leakage. Therefore, a completely non-hydraulic coal mine support is needed to achieve the goal of environmental protection and pollution-free. Secondly, with the continuous increase in coal mining depth and the increasingly complex mining conditions, the requirements for coal mine support equipment are also getting higher and higher. The pressure-relieving performance of electric supports is limited, and it is difficult to adapt to the drastic pressure changes that may occur during coal mining. When the roof pressure suddenly increases, the support may not be able to release the pressure in a timely and effective manner, resulting in damage to the support and even causing safety accidents. At the same time, it cannot accurately sense the pressure when working, and the support urgently needs to be modified. Summary of the Invention
