Description

A small lifting device for building construction

technical field

The invention relates to the field of construction machinery, in particular to a small lifting device for construction.

Background technique

Today, with the rapid development of the national economy, construction machinery such as construction elevators has begun to play a huge role in more and more construction fields, especially for large projects and high-rise building sites, the use of construction elevators is particularly important, which can greatly improve productivity and save labor time. Therefore, people have higher and higher comprehensive requirements for the performance, efficiency, load capacity, energy saving and maintenance of elevators. At present, the transmission mechanism of the construction elevator uses a pin-type overload sensor to connect the transmission mechanism and the cage. This kind of pin-type overload sensor is a pin-type force, the force-bearing area is small, easy to damage, and the structure processing is also complicated; installation When installing the lug plate, the accuracy of the hole position is high, and the hole position needs to be corrected, especially the existing welding technology will produce stress deformation, so secondary processing is often performed when installing the pin-type overload sensor, resulting in increased labor and other costs. Moreover, the transmission mechanism and the hanging cage cannot be interchanged at will.
