Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a lifting device for civil engineering. Background Art

[0002] Lifting devices for civil engineering are indispensable and important equipment on construction sites. They are mainly used to lift and move heavy construction materials, components and equipment. These devices are usually composed of a sturdy steel structure frame, a high-performance lifting motor, a sophisticated control system and durable lifting ropes or chains. They can ensure that various lifting tasks can be completed safely and efficiently in complex and changing construction environments, providing strong support for the smooth progress of civil engineering projects.

[0003] However, existing civil engineering hoisting devices do not have the function of cleaning the hoisting rope during use, which will cause dust, dirt and possible corrosion products to accumulate on the surface of the hoisting rope. This not only increases the friction coefficient between the hoisting rope and the cargo, reducing the hoisting efficiency, but may also accelerate the wear of the hoisting rope due to frictional heat, shortening its service life. In some extreme cases, the accumulation of pollutants may even cause safety hazards during the hoisting process, such as rope breakage, seriously threatening the safety of personnel on the construction site and the progress of the project.

[0004] Therefore, a lifting device for civil engineering is proposed. Utility Model Content

[0010] Further preferably, a hoisting motor for driving the winding roller to rotate is fixedly mounted on the front surface of the hoisting frame, and the output end of the hoisting motor is fixedly connected to the middle end of the front surface of the winding roller.

[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5As shown, the embodiment of the utility model provides a lifting device for civil engineering, including a lifting frame 1, comprising a lifting frame 1, a winding roller 2 movably connected to the inner side of the lifting frame 1, a lifting rope 4 wound around the surface of the winding roller 2, a liquid storage tank 9 fixedly connected to the back side of the lifting frame 1, a fixed frame 10 fixedly connected to the bottom of the liquid storage tank 9, an inner cavity of the fixed frame 10 movably connected to a crankshaft 12 through a bearing, a movable sleeve 13 movably connected to the surface of the crankshaft 12, and a transmission rod 14 movably connected to the bottom of the movable sleeve 13. The bottom of the transmission rod 14 is movably connected to a connecting rod 15, and the front side of the connecting rod 15 is fixedly connected to a cleaning ring 7, which is located on the outside of the sling rope 4, and the inner side of the cleaning ring 7 is in contact with the surface of the sling rope 4. A servo motor 11 for driving the crankshaft 12 to rotate is fixedly installed on the back side of the fixed frame 10, and the output end of the servo motor 11 is fixedly connected to the back side of the crankshaft 12. A slide 16 is fixedly connected to the back side of the bottom of the fixed frame 10, and the back side of the connecting rod 15 is slidably connected to the inner cavity of the slide 16.

[0026] In this embodiment, the crankshaft 12 utilizes the crank mechanism principle to drive the connecting rod 15 up and down through the movable sleeve 13 and the transmission rod 14 during the rotation process. The connecting rod 15 drives the cleaning ring 7 to move up and down along the surface of the lifting rope 4. During the process of retracting and extending the lifting rope 4, the surface of the lifting rope 4 is repeatedly scrubbed, which can instantly remove dirt and residue on the surface of the lifting rope 4, keep the lifting rope 4 clean and smooth, thereby improving the safety and efficiency of the lifting operation, and also helping to extend the service life of the lifting rope 4 and reduce the replacement cost caused by pollution or wear. By setting the slide 16, the connecting rod 15 can be limited, and at the same time, the smoothness of the connecting rod 15 in the process of moving up and down can be effectively improved.

The atomizing nozzle 8 atomizes the coolant and sprays it to the hoisting rope 4, which can effectively reduce the heat generated by the long-term friction of the hoisting rope 4. The coolant is evenly covered on the hoisting rope 4 by the atomizing spray method, which achieves rapid cooling, thereby protecting the hoisting rope 4 from high temperature damage, improving the safety and stability of the hoisting operation, and also helping to reduce The risk of aging or breaking of the lifting rope 4 due to overheating, and at the same time, the output end of the servo motor 11 drives the crankshaft 12 to rotate. During the rotation process, the crankshaft 12 uses the principle of the crank mechanism to drive the connecting rod 15 up and down through the movable sleeve 13 and the transmission rod 14. The connecting rod 15 drives the cleaning ring 7 to move up and down along the surface of the lifting rope 4. During the process of retracting and extending the lifting rope 4, the surface of the lifting rope 4 is repeatedly scrubbed, which can instantly remove dirt and residue on the surface of the lifting rope 4, keep the lifting rope 4 clean and smooth, thereby improving the safety and efficiency of the lifting operation, and also helping to extend the service life of the lifting rope 4 and reduce the replacement cost caused by pollution or wear.
