Detailed Description

The terminology used in the description of the embodiments of the invention section is only used for explaining the specific embodiments of the invention and is not intended to limit the invention.

The vertical elevator (also known as vertical elevator, elevator) is one kind of elevator, and is a vertical elevator powered by motor and equipped with box-like nacelle for carrying people or goods in multi-story building. It has a cage which runs between at least two rows of vertical or inclined rigid guide rails with an angle of inclination of less than 15 deg.. The size and the structural form of the car are convenient for passengers to access or load and unload goods. The vertical elevator is the earliest elevator and is one of the most common elevator types in life.

The structure of an upright elevator comprises four large spaces and eight large systems. The four spaces are respectively a machine room part, a shaft and pit part, a car part and a landing part. The eight systems are respectively a traction system, a guide system, a lift car, a door system, a weight balance system, an electric traction system, an electric control system and a safety protection system.

The main function of the traction system is to output and transmit power to enable the elevator to run. The traction system mainly comprises a traction machine, a traction rope (such as a steel belt), a guide wheel, a diversion sheave and the like. The traction machine is power equipment of an elevator, and mainly comprises a motor, a brake, a coupler, a reduction gearbox, a traction wheel, a rack, a guide wheel, an auxiliary turning hand wheel and the like. The guide wheels are typically mounted on the frame or on a load beam below the frame. Some of the barring hand wheels are fixed on the motor shaft, and also hung on a nearby wall at ordinary times, and then sleeved on the motor shaft when in use.

When the elevator is used, two ends of a traction rope (such as a steel belt) are respectively connected with the car and the counterweight and wound on the traction sheave and the guide wheel, the motor drives the traction sheave to rotate after the speed of the speed reducer is changed, and the car and the counterweight move up and down by virtue of traction force generated by friction between the traction rope and the traction sheave, so that the purpose of transportation is achieved. The guide shoes fixed on the car can reciprocate along the fixed guide rails arranged on the wall body of the hoistway of the building to prevent the car from deflecting or swinging in the operation. The brake is released when the motor works to enable the elevator to run, and the brake is used for stopping the lift car from lifting under the condition of power failure and maintaining the static state of the car on a specified landing for people and goods to enter and exit. The car is a box member that carries passengers or other loads and the counterweight is used to balance the car load and reduce motor power. The electric control system realizes the control of the elevator movement and simultaneously completes the work of floor selection, floor leveling, speed measurement and illumination. The safety protection system ensures the safety of the elevator operation.

Meanwhile, the anti-jumping device is arranged on the rack, and is covered at one end of the traction sheave, which is deviated from the extending direction of the steel belt, and the two opposite sides of the traction sheave supporting the steel belt. In the second aspect, the anti-jump device can guide the steel belt in the process that the steel belt is wound to the traction sheave, so that the steel belt is convenient to install, operate, maintain and protect, and the work efficiency is improved. In the third aspect, the anti-jumping device can prevent foreign matters in the elevator shaft from polluting the traction wheel, so that the steel belt can be prevented from slipping, and the reliability and the safety of the traction machine for driving the elevator device to work can be guaranteed.
