Description

Technical Field

[0001] The present application belongs to the technical field of lifting devices, and specifically relates to a lifting device for installing electromechanical equipment in a hydropower station. Background Art

[0002] The lifting devices for the installation of electromechanical equipment in hydropower stations usually include lifting equipment, lifting tools and installation auxiliary equipment, etc. They play an important role in the construction and maintenance of hydropower stations, and can improve the installation efficiency and quality of electromechanical equipment and ensure the safe operation of electromechanical equipment.

[0003] For example, the utility model patent with announcement number CN220265111U discloses a hydropower station electromechanical equipment installation and lifting device, including a support frame, and first slide grooves are opened on both sides of the support frame; the utility model is provided with a first slide groove, a first limit block and a control block, which is convenient for use. When the staff starts the first motor, the start of the first motor causes the wire wheel to gradually reel in the traction wire to drive the support plate to gradually rise, and the first limit block slides in the first slide groove to limit the support plate. When the support plate reaches the installation height, the staff starts the control block, and the control block causes the second electric push rod to gradually extend the inner wall to squeeze, so that the position of the support plate is fixed, and the staff removes the equipment, thereby avoiding the situation that when the equipment is removed, the traction wire has toughness and the support plate loses the weight of the equipment, causing the traction wire to have elastic force, causing the support plate to swing up and down in the first slide groove, which causes danger to the staff when moving the equipment.

[0004] However, it was found during actual use that: the lifting device supports the electromechanical equipment lifting mechanism through the support frame, and uses the universal wheels at the bottom of the support frame to drive the lifting mechanism to move; however, since the support frame is only maintained stable by the universal wheels at the bottom during use, the electromechanical equipment on the support plate can easily cause the support frame to shake and move during operation, posing certain safety hazards. Therefore, a lifting device for installing electromechanical equipment in a hydropower station is provided. Utility Model Content
