Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a material lifting frame. Background Art

[0002] During the construction process, it is usually necessary to lift the ground materials and transport them to the upper working area. During this process, a lifting device is needed for transportation. The material lifting frame is the frame used by the material hoist to load the materials.

[0003] After searching, the existing Chinese patent with publication number CN202123076680.X discloses a construction material hoist. In the process of the lifting platform moving upward, the pulleys on both sides of the lifting platform will move upward along the slide groove. The slide groove plays a role in limiting the movement trajectory of the pulley, thereby ensuring that the lifting platform is in a horizontal state during the rising process, avoiding the lifting platform from shaking and causing the material to slip, and ensuring the safety of the logistics rising process. The machine drives the transmission rod to rotate clockwise, and the clockwise rotation of the transmission rod will drive the first I-shaped wheel to rotate clockwise, thereby driving the steel cable to rewind on the outer surface of the first I-shaped wheel, and using the second I-shaped wheel to change the rewinding direction of the steel cable, thereby driving the lifting platform to move upward.

[0004] The above technical solution has the following defects: although such a material hoist can be lifted and lowered by a user crane to drive the material lifting frame, in actual use, the materials transported to a high place still need to be manually unloaded by staff, and the material lifting frame is usually directly connected to the hoist and is difficult to dismantle. After the materials are lifted, the staff need to move the internal carrying materials down one by one, which is quite laborious. For this reason, a material lifting frame is proposed, which can be separated from the material hoist after being lifted to a high place and moved in the building to transport materials, and after loading the materials, it is easy to connect to the material hoist to transport materials, thereby improving the efficiency of material transportation.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
