[0003] The present invention designs a new type of household screw platform elevator, which is used to overcome the defects in the prior art that the elevator takes up a large space, runs slowly, vibrates obviously, makes noise, and costs high in production and maintenance, and can especially meet the needs of existing elevators. The need to install elevators in buildings with small hoistway space in the middle of wrap-around stairs

Abstract
The invention discloses a novel household screw platform elevator. The novel household screw platform elevator comprises a guide rail base, a guide rail, two rows of bearing channel steel, a tensioning wheel, a steel belt rope end, a backpack frame, a platform guide shoe, a platform frame, a platform plate, a safety clamp braking device, a motor, a coupler, a motor mounting plate assembly, a lowerbearing seat, a lower guide wheel assembly, a sliding guide shoe, a screw, a limit protector, an upper guide wheel assembly, a screw upper fixing frame, an upper bearing seat, a speed limiter and aninner curtain wall. According to the novel household screw platform elevator, when the motor rotates, the screw is driven to rotate, two positive and negative nuts mounted on the screw do linear motion to drive the upper and lower guide wheels connected with the nuts to do relative motion, so that the steel belt wound on the guide wheels is dragged to retract or release, and the retracting or releasing distance of the steel belt is four times of the relative operation distance of the positive and negative nuts; and the use length of the screw is greatly shortened, so that the production and maintenance costs are greatly reduced.
Description
technical field [0001] The invention relates to the field of household elevators, in particular to a novel household screw platform elevator. Background technique [0002] At present, there are three driving modes of platform ladders: the first is a traction platform ladder, the second is a hydraulically driven platform ladder, and the third is a conventional screw-type platform ladder. Conventional screw-type platform ladders have disadvantages such as slow running speed, loud noise, obvious jitter, and high manufacturing cost. In addition, the load-bearing main nut of the screw-type elevator is easy to wear during operation, and the maintenance cost in the later period is high, so the elevator with this structure is not easy to use frequently. The hydraulic pump of the hydraulically driven elevator is noisy when it is working, the oil cylinder and oil pipe seals are prone to oil leakage, polluting the environment, the pump station takes up space, the temperature of the ...
