Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment underground for coal mine electromechanical transportation, and specifically to a hoisting equipment for coal mine electromechanical transportation. Background Art

[0002] In coal mine exploitation, especially underground coal mine exploitation, generally, electromechanical equipment such as mining equipment, electrical equipment, ventilation equipment, motors, and cables is required for auxiliary exploitation. When these relatively small equipment are installed or used underground, generally, components such as steel frame supports and steel frame supports are also required. These equipment are often heavy, which leads to the need to use special hoisting equipment for installation, transportation, and use when transporting, installing, or using electromechanical equipment underground. For underground, due to limited space, due to the frame structure of the hoisting equipment, it is currently difficult for the existing hoisting equipment to directly input the entire hoisting equipment into the underground using conveying equipment. This requires disassembling the hoisting equipment and then reassembling it underground, which results in low efficiency. Moreover, the underground space, visibility, etc. are all affected, resulting in low hoisting efficiency and inconvenience in moving and transporting the hoisting equipment to the underground for direct use. In addition, the underground ground is often uneven, which makes it difficult to achieve good leveling during the installation of the hoisting equipment, resulting in low hoisting efficiency. Leveling takes a long time and the stability is poor. In addition, due to limited space underground, the supporting area of the hoisting frame is limited, which leads to limited stability during hoisting of heavy equipment or when it is difficult to achieve symmetric and balanced hoisting, affecting the stability and safety of hoisting.
