Circular hoist for construction

Abstract

The invention relates to the field of building construction, in particular to a circular lifting machine for construction. The circular lifting machine for construction comprises a bidirectional drivedevice, a bearing primary body, a bearing secondary body, a manual lifting device and two pulley groups. The bearing secondary body can be movably arranged in the bearing primary body by the manual lifting device in an inserting mode, and the two pulley groups are separately installed on the front and rear sides of the bearing secondary body. The bidirectional drive device comprises a servo motorand two quick-dismounting disks, the servo motor is separately and detachably connected to the pulley groups in a transmission mode through the two quick-dismounting disks, the servo motor is used for driving the two quick-dismounting disks to separately rotate around axes of the two quick-dismounting disks. An anti-dropping rope block is installed on one side of the top end of the bearing primary body. The circular lifting machine for construction is simple in structure, the cost is low, automatic handling is performed in the case of more materials, manual operation is performed in case of less materials, installation operations are saved, and meanwhile, the circular lifting machine for construction is convenient to use because the circular lifting machine can be disassembled.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a circulating hoist for building. Background technique [0002] In daily construction work, humans need to carry out construction work on the roof. For some higher roofs, humans will use large-scale lifting equipment, but now there are many shorter buildings, and the height of these buildings is usually below 8 meters. For the roof construction operation of this kind of building, it is not realistic to use large-scale lifting equipment, so some construction tools and materials can only be passed manually by several people. In this way, there is a risk of people falling, and there are some skilled workers who directly throw upwards with their hands. This requires very high requirements for operators, and there are still potential safety hazards, and some materials use It is relatively frequent and the quantity is large. At the same time, the area of ​​the roof of the building...

[0002] In daily construction work, humans need to carry out construction work on the roof. For some higher roofs, humans will use large-scale lifting equipment, but now there are many shorter buildings, and the height of these buildings is usually below 8 meters. For the roof construction operation of this kind of building, it is not realistic to use large-scale lifting equipment, so some construction tools and materials can only be passed manually by several people. In this way, there is a risk of people falling, and there are some skilled workers who directly throw upwards with their hands. This requires very high requirements for operators, and there are still potential safety hazards, and some materials use It is relatively frequent and the quantity is large. At the same time, the area of ​​the roof of the building is limited, and a large amount of materials cannot be placed at the same time, so it can only be transported quantitatively. In this case, repeated manual operations will greatly waste energy
