The invention relates to the technical field of elevators, and discloses an improved screw elevator with a stable fixed framework. The improved screw elevator comprises a car and a screw transmissionassembly for driving the car to lift, and further comprises a connecting block, wherein the screw transmission assembly comprises a guide rail assembly, a screw assembly and a power assembly; the guide rail assembly at least comprises two guide rails which are oppositely arranged, nut cavities are arranged in the guide rails; openings are formed in positions, on opposite surfaces of the two guiderails, of the nut cavities; the screw assembly comprises at least two drive screws, and the two drive screws are in one-to-one correspondence to the two guide rails; the drive screws are positioned inthe nut cavities; the drive screw is rotatably mounted on the connecting block; the connecting block passes through the openings and is fixedly mounted on a connecting framework of the car; and the power assembly drives the drive screws to rotate. The improved screw elevator with the stable fixed framework greatly improves use safety of the elevator, overcomes the problem that length of the screwis limited, and breaks through the limitation of the original biggest storey height.
Description
technical field [0001] The invention relates to the field of elevators, in particular to an improved screw elevator with a stable and fixed frame. Background technique [0002] Elevators generally include traction elevators, hydraulic elevators, and screw elevators. The latter two are mainly used in low-rise buildings. In the process of elevator use, safety is the most important factor. Hydraulic elevators are gradually replaced by screw elevators due to easy oil leakage, complicated installation, and constant maintenance. Screw elevators are widely used in buildings with 2 to 5 floors because of their safety, simple structure, and automatic shutdown when power is off. [0003] Screw elevators generally include nut rotation drive type and screw rotation drive type. Both of them are installed because the screw needs to be installed in the air from the lowest end to the top end, which limits the length of the screw to only adapt to the height of 2 to 5 floors. The disadvant...
