Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of municipal engineering construction, and particularly relates to an auxiliary hoisting tool for concrete pipes. Background Art
[0002] In municipal pipeline projects, pipes serve as the "blood vessels" of the system, their lifeblood. The quality of the pipes themselves, their protection during construction, and the quality of their installation directly impact the overall quality of the system and its subsequent operational and maintenance costs. With the continuous development of society and the economy, the use of pipe materials in municipal pipeline projects has become increasingly diversified. New pipe materials such as polyethylene (PE) pipe, rigid polyvinyl chloride (PVC-U) pipe, and high-density polyethylene (HDPE) spiral pipe are increasingly challenging the market for traditional pipe materials such as concrete pipe, steel pipe, and ductile iron pipe. However, concrete pipes remain a dominant force in municipal pipeline systems due to their inherent strength, durability, ease of construction, and excellent seismic resistance. However, protecting concrete pipes from the moment they leave the manufacturer until they are installed and commissioned is crucial and challenging. This is particularly true during loading, unloading, and installation, where damage is more likely to occur, compromising pipe quality and functionality. For example, in the current construction of pipeline projects, when loading, unloading and installing concrete pipes, on-site workers ignore or do not know how to protect the hoisted concrete pipes, resulting in direct contact between the lifting ropes and the concrete pipes during loading, unloading and installation of the concrete pipes, causing the concrete pipes to be directly deformed or damaged by force. At the very least, the pipelines will be abandoned, increasing some construction costs, and at worst, it will affect the overall quality of the pipeline system and the subsequent operation and maintenance costs. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide an auxiliary lifting tool which has a simple structure, is easy to use, can effectively improve the loading and unloading efficiency of concrete pipes and prolong the service life of concrete pipes.
[0004] The technical solution of the utility model is: a concrete pipe auxiliary lifting tool, including: a lifting ear, a fixing rope, and a force-bearing plate, the lifting ear is rotatably connected to one end of the force-bearing plate, the lifting ear is connected to the crane through a lifting rope, the end of the fixing rope is fixedly connected to the other end of the force-bearing plate, the force-bearing plate is a C-shaped structure, the groove of the force-bearing plate is engaged with the pipe mouth of the concrete pipe, two of the lifting ears, the fixing rope and the two force-bearing plates are connected to form the concrete pipe auxiliary lifting tool.
[0005] Furthermore, the lifting lug is a U-shaped shackle.
[0006] Furthermore, a circular hole is opened at the end of the load-bearing plate, and the groove of the load-bearing plate is 30-40 cm deep.
[0007] The beneficial effects of the utility model: The utility model is a concrete pipe auxiliary lifting tool with a simple structure and easy use. The lifting ear is rotatably connected to one end of the load-bearing plate, the lifting ear is connected to the crane through a lifting rope, and then the end of the fixed rope is fixedly connected to the other end of the load-bearing plate. Finally, the groove of the load-bearing plate is engaged with the pipe mouth of the concrete pipe, so that the pipe mouth of the concrete pipe is wrapped and protected by the load-bearing plate during lifting and will not be damaged by friction of the lifting rope, thereby extending the service life of the concrete pipe while ensuring the safety of the lifting operation.
