Description

Technical Field

[0001] The utility model relates to the field of lifting equipment, in particular to a lifting device for construction engineering. Background Art

[0002] Lifts are mechanical equipment driven by hydraulic cylinders or chains, mainly used for high-altitude operations and maintenance. Lifts are made of high-strength high-quality aluminum alloy materials, with the advantages of beautiful appearance, small size, light weight, balanced lifting, safety and reliability, and can be operated up and down. They are widely used in the construction field, such as building construction, exterior wall decoration, bridge maintenance, road maintenance, and high-altitude landscape pruning. They can improve construction efficiency, reduce labor intensity, and ensure construction safety.

[0003] After massive searches, it was found that the Chinese patent with the prior art publication number CN214456629U disclosed a lifting device for construction. The patent starts the lifting hydraulic press, and the hydraulic shaft of the lifting hydraulic press rises to drive the top plate to rise, so as to transport people and materials upward again. After the transportation is completed, the hydraulic shaft of the lifting hydraulic press moves downward to restore the top plate to its original position, and the bolt is rotated outward to separate the left side wall of the bolt from the outer side wall of the telescopic column. The hydraulic shaft of the main hydraulic press moves downward to restore the middle plate to its original position, and the hydraulic shaft of the slave hydraulic press moves downward to restore the bottom plate to its original position, so that the entire device can rise to a higher position and is easy to operate. However, in this scheme, due to the limited space on the top plate, the workers on the top plate will use tools when constructing the building, and the tools will be placed on the top plate after use, resulting in the limited space on the top plate being occupied, which is not conducive to the activities of the workers on the top plate and affects the use of the lifting device by the workers. Therefore, based on the above search and combined with the prior art, the utility model proposes a lifting device for construction engineering to solve the above problems. Utility Model Content
