A small lifting device for building construction

Abstract

Small lifting equipment for building operations comprises a bottom board, a support device, a lifting device, a supporting table device, a balance device, a fixing device and an air cylinder device. The bottom board is provided with idler wheels and a first balancing weight. The support device is provided with a first supporting rod, a first spring, a first abutting rod, a rotary portion and the like. The lifting device is provided with a first transverse board, a first inclined rod, a first motor, an output shaft, a connection line and the like. The supporting table device is provided with a supporting table, a first supporting block, a second supporting block, a first fixing frame, a second vertical rod and the like. The balance device is provided with a third transverse rod, a fourth transverse rod, a third inclined rod, a first rotary wheel and the like. The fixing device is provided with a fourth inclined rod, a third vertical rod, a fifth inclined rod, a fourth vertical rod and the like. The air cylinder device is provided with an air cylinder, a first fixing rod, a second fixing frame, a bent rod and the like. A constructer can be smoothly lifted to the required height, the use range of products is expanded largely, and the product reliability is improved through lifting of double efforts.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a small lifting device for construction. Background technique [0002] 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 al...

AI Technical Summary

Problems solved by technology

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.
