Description

A screw-type single-person lift

technical field

The utility model relates to an elevator, in particular to a screw rod type single person elevator.

Background technique

Elevator is a kind of vertical elevator powered by electric motor , equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. According to the speed, it can be divided into low-speed elevators (below 1 m/s), fast elevators (1~2 m/s) and high-speed elevators (above 2 m/s). Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings today. In 1852, EG Otis of the United States developed a safety elevator for wire rope lifting. In the 1980s, the driving device was further improved, such as the motor driving the winding reel through the worm drive, and the use of a balance weight. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator. With the development of society, the use of elevators is becoming more and more popular, and even two or three floors are equipped with elevators. For families, installing a single-person motor can realize fast up and down stairs, which is very convenient for people who carry items or have disabilities. Most of the vertical elevators currently on the market are equipped with a motor on the top of the floor, which is driven up and down by a belt or chain. This kind of elevator has poor stability and is prone to failure.

Utility model content

The purpose of this utility model is just to provide a kind of screw type single-person lift in order to solve the above problems.

The utility model realizes above-mentioned purpose through following technical scheme:

A screw-type single-person elevator, comprising a bridge box and a fixed bracket, the bridge box is arranged in front of the fixed bracket, a lifting seat is arranged in the middle of the fixed bracket, and sliding seats are arranged at the four corners of the fixed bracket. Seat, the middle of the lifting seat is provided with a driving screw, the upper and lower sides of the driving screw are provided with fixed beams, the end of the driving screw is provided with a limit seat, and the two ends of the fixed beam are provided with guide shafts. A driving motor is arranged at the bottom of the driving screw rod, and the driving motor is connected with a PLC controller.

Further, the fixing bracket is fixed on the rear of the axle box by bolts, the sliding seat is fixed on the center of the fixing bracket by screws, and the sliding seat is fixed on the driving screw by threads.

Further, balls are arranged inside the sliding seat.

Further, there are two guide shafts in total, and the two guide shafts are parallel to each other. The guide shafts are fixed on the wall by bolts, and the sliding seat is buckled on the guide shafts.

Further, the fixed beam is fixed between the guide shafts through bolts, the driving screw is fixed on the fixed beam through the limit seat, and a bearing seat is arranged inside the limit seat.

Further, the driving motor is fixed on the wall by bolts, and an electromagnetic clutch is arranged between the driving motor and the driving screw.

In the above structure, when the elevator needs to be used, the operator sends a signal to the PLC controller by pressing the floor button inside the elevator, and the PLC controller controls the rotation of the drive motor to drive the rotation of the drive screw, and the drive screw The forward or reverse rotation of the rod drives the fixed support up or down, thereby driving the axle box up and down to complete the process from low to high or from high to low.

The utility model has the beneficial effects of simple structure, convenient installation, good stability, high safety and low cost by using the screw rod for transmission.
