Description

An elevator driven by a worm and worm bar mechanism

technical field

The utility model relates to the technical field of elevators, in particular to an elevator driven by a worm bar mechanism.

Background technique

At about 18:00 on July 15, 2015, an employee elevator accident occurred in the office building of Huayang International Building in Heping District, Shenyang City. The elevator car began to fall from the 27th floor, and fell straight from the 12th floor to the first floor.

At present, the driving method adopted by most elevators is that the steel wire rope pulls the elevator car to move up and down along the guide rail. However, when the faulty mechanism is out of control, the elevator car will fall along the smooth guide rail, or rise under the traction of the counterweight, causing passengers to be injured. In addition, due to the extension elasticity of the steel wire rope and the vibration in the horizontal direction, it may bump up and down even during normal use, which may easily cause passengers to feel unsafe.

Utility model content

The technical problem to be solved by the utility model is to provide an elevator driven by a worm-screw bar mechanism to solve the safety problem of the elevator fundamentally.

The utility model adopts the following technical solutions for solving the above-mentioned technical problems:

An elevator driven by a worm and worm bar mechanism, comprising a guide rail, a slider, a car and a drive module, the drive module comprising a worm, a motor, a gear set and a housing;

The slider is arranged on the guide rail;

The guide rail is a T-shaped guide rail, which includes a fixing part and a locking part, wherein the fixing part is vertically arranged on the wall, and the locking part is used to cooperate with the slider, so that the slider can move along the locking part. slide up and down;

The car is fixedly connected to the slider, and the motor is fixedly connected to the car;

A worm bar matched with the worm is provided on the clamping part of the guide rail along the sliding direction of the slider, and the worm bar faces the car;

The gear set includes a driving gear, a transmission gear and a driven gear;

The axis of the driving gear is fixedly connected with the output shaft of the motor, the axis of the driven gear is fixedly connected with one end of the worm shaft, and the transmission gear meshes with the driving gear and the driven gear respectively. The worm is matched with the worm bar;

The housing is used to fix the relative positions of the worm, the motor and the gear set, and is connected to both ends of the worm shaft through bearings.

As a further optimization scheme of the elevator driven by the worm bar mechanism of the present invention, the driving module is arranged on the top of the car, and the motor is fixedly connected to the top of the car.

Compared with the prior art by adopting the above technical scheme, the utility model has the following technical effects:

1. Utilizing the self-locking phenomenon of the meshing of the worm and worm bars, the elevator car cannot slide arbitrarily, ensuring that there will be no uncontrolled rise and fall at any time, and the safety is guaranteed;

2. The electric motor is used to drive the worm to rotate and drive the car to move in a straight line. It is easy to start and the control is simple and precise, and it can achieve precise and stable operation;

3. The guide rail is directly fixed on the wall, the installation is firm and stable, and the rigidity is good, and the passengers will not bump up and down when entering and exiting the elevator car.

detailed description

Below in conjunction with accompanying drawing, the technical scheme of the utility model is described in further detail:

As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model discloses an elevator driven by a worm and worm bar mechanism, which includes a guide rail, a slider, a car and a drive module, and the drive module includes a worm, a motor, gear sets and housings;

The slider is arranged on the guide rail;

The guide rail is a T-shaped guide rail, which includes a fixing part and a locking part, wherein the fixing part is vertically arranged on the wall, and the locking part is used to cooperate with the slider, so that the slider can move along the locking part. slide up and down;

The car is fixedly connected to the slider, and the motor is fixedly connected to the car;

A worm bar matched with the worm is provided on the clamping part of the guide rail along the sliding direction of the slider, and the worm bar faces the car;

The gear set includes a driving gear, a transmission gear and a driven gear;

The axis of the driving gear is fixedly connected with the output shaft of the motor, the axis of the driven gear is fixedly connected with one end of the worm shaft, and the transmission gear meshes with the driving gear and the driven gear respectively. The worm is matched with the worm bar;

The housing is used to fix the relative positions of the worm, the motor and the gear set, and is connected to both ends of the worm shaft through bearings.

The drive module is preferably arranged on the top of the car, and the motor is fixedly connected to the top of the car.

The utility model uses a worm worm bar mechanism to drive the elevator. The worm bar is arranged outside the T-shaped vertical guide rail fixed on the wall. The worm is fixed on the top of the elevator car and cooperates with the worm bar on the outer side of the guide rail. The motor passes through the gear The group drives the worm to rotate, producing linear motion in the up and down direction, driving the elevator car to rise and fall. The side of the elevator car close to the guide rail is provided with a slider, which cooperates with the guide rail to limit the direction of movement of the elevator car.
