Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to an auxiliary lifting device for electromechanical pipelines in a limited space. Background Art
[0002] When encountering construction in limited spaces such as pipe corridors and walkways, due to the high clearance requirements, there are pipelines such as air ducts, air conditioning water pipes, fire protection pipes, and strong and weak power bridges in the same space. Therefore, under the premise of meeting the functions and later operation and maintenance, the reasonable and beautiful arrangement of pipeline directions and the setting of brackets are the key to ensure the clear height requirements. However, since the space in these areas is often not large, the distance between the pipeline installation and the top is mostly within two meters, and the installation width is within three meters. After the bracket is installed, there is no room for conventional lifting equipment to be used. Large lifting machinery and equipment cannot enter. When constructing in these areas, the lifting of materials has become a key factor that troubles construction workers. Traditional material lifting requires setting a fixed lifting point on the top plate or a higher shear wall to hang the lifting device. It is necessary to find a fixed point at a higher point of the installation site (generally greater than 1000mm) and use steel plates, expansion anchor bolts and other materials to set a lifting point on the shear wall or on the steel beam for material lifting. After the material is hoisted, use a cutting machine to cut off the lifting point. This method cannot be reused after use, which is time-consuming, labor-intensive, environmentally unfriendly, and material-inefficient. It is also easy to damage the structural walls and poses safety hazards. In addition, the locations where the hanging points are installed need to be decorated by decoration professionals. If there are steel structure hanging points, rust removal, grinding, and fire-retardant coating are required. The subsequent maintenance requires a lot of work.
[0003] In summary, there is an urgent need for a material lifting device suitable for construction in a narrow area to solve the problems existing in the prior art. Utility Model Content

The limit block 6 can be made of angle steel.
[0024] Preferably, a second opening for installing the fixed pulley is provided on the cantilever slab 2. The installation of the fixed pulley can facilitate the installation of a manual chain hoist or other lifting ropes and hooks, thereby facilitating the lifting of pipelines or other heavy objects.
