Description

Threaded rod type elevator and transmission system

Technical Field

The utility model belongs to the technical field of, concretely relates to screw rod formula elevator and transmission system.

Background

Elevators are common tools for achieving vertical lift in buildings, especially for high-rise buildings, and are essential tools for people and goods to enter and exit the buildings. For single multi-story buildings with high room clearance or relatively low building height, people tend to walk up and down stairs. But for some special people or special situations, the use of the stairs is often not convenient enough. For example, it is inconvenient for a patient or an elderly person with poor mobility to go up and down stairs; or it is very laborious and time-consuming to go up and down through stairs while carrying heavy objects. Because the existing elevator is mainly arranged in a special shaft, the elevator cannot be built by the original mode after the construction is finished. Therefore, there is a great demand in the market today for the construction of elevators in multi-story buildings or existing buildings, especially duplex and villa-like buildings.

According to the prior patent numbers: CN210214510U discloses a screw elevator and transmission system, belongs to elevator transmission technical field. The screw type elevator transmission system comprises a screw and a nut which are driven by a motor, and a brake mechanism is arranged on the outer circumference of the nut. The brake mechanism comprises a brake seat, a brake pad and an electromagnet which are sleeved on a screw rod, a nut or the periphery of an output shaft of the power device. The brake seat and the electromagnet are fixed on two sides of the brake pad; a spring which generates elastic force opposite to the electromagnetic acting force of the electromagnet on the brake pad is arranged between the brake pad and the electromagnet or between the brake seat and the brake pad, and the brake pad reciprocates under the action of the elastic force of the spring and the electromagnetic force to realize the braking and the release of the brake pad on a rotating part; the rotating part is movably connected with the brake pad through the matching of the groove and the bulge structure. The transmission system is simple in structure, firm and durable, and can remarkably improve the stability and safety of the screw type elevator.

But this electric brake structure security is lower, because the screw elevator wholly uses through threaded rod and the spiro cooperation rotation that possesses the internal thread to go up and down, but elevator manned back weight is heavier, add the weight that the elevator originally saved and can reach two tons, when weight is heavier, thereby the screw thread on threaded rod and the spiro can receive the elevator that the bottom is heavier to damage, make the screw thread drop from screw rod, spiro, and brake structure only prescribes a limit to screw rod, spiro and prevents rotatoryly, but after the screw thread drops, the spiro can directly slide from the screw rod outside like the sleeve, make the elevator directly fall into the bottom, do not possess the effect of self-protection simultaneously, the problem of potential safety hazard and the work degree of difficulty has been increased, we provide a screw rod elevator and transmission system for this reason.
