What Do Elevator Constructors Do?

The internal structure of the elevator is the core of the elevator, including inverter, brake, buffer, safety gear, speed limiter, lead-in device, automatic switch, transformer, rectifier, knife switch, transfer switch, contactor, electromagnetic relay, selector, main Order electrical appliances, terminal switches, door interlocking contacts, brake solenoids, light signal panels, floor light signals, signal displays, signal bells, guide rails, ladder wells, machine rooms, car elevators, platforms, counterweights

Elevator internal structure

Right!

The internal structure of the elevator is the core of the elevator, including inverters,

A component that adjusts the frequency of the electric wave to achieve the purpose of adjusting the speed of the elevator and saving power.

Electric and spring-driven components responsible for stopping the elevator,

The bumper is an elevator safety device that provides the last kind of safety protection. It is installed in the elevator

Speed limiter is a control

The lead-in device consists of a knife switch and a penetrating capacitive filter installed in a metal housing. When the elevator is out of service for a long time, use the switch to cut off the power. Filters are used to prevent interference with radio reception

Automatic switch on the elevator for protection

The transformer on the elevator is used to reduce the voltage to the control circuit, car lighting circuit, signal and repair lighting circuit. This kind of transformer is called

The knife switch is mounted on a separate insulating plate or control panel. When connected

Contactors are used to remotely close and cut off electrical circuits. Use of power contacts of contactors

Selector for automatic selection

The main electrical appliance refers to a control appliance that is directly operated by the driver or passenger when the elevator is started or stopped.

Terminal switch is located in the ladder well or on the hoist for protection

The interlocking contacts of the door are used to check the condition of the elevator well and the car door and the elevator well lock.

Classified by power supply category and core rated travel value. According to the power supply category, the electromagnet is divided into DC and AC (three-phase and single-phase); according to the rated travel value of the core, it can be divided into long stroke (30 ~ 120mm stroke) and short stroke (2 ~ 5mm stroke). Compared with AC electromagnets, DC electromagnets have a greater number of closings per hour, less noise, and smooth operation.

It is used to display the signal of the position of the car in the ladder well, and to record the light signal called from the floor platform. In the instructions

Passenger elevators for public buildings. The middle floor is installed with two lights and directional light signals, and the bottom and top floors are installed with one light and single directional light signals.

Used to signal empty call

For calling

Arranged like a track at the full height of the ladder well for correct guidance

The room is equipped with electrical lighting, and some are equipped with heating and ventilation equipment.

The horizontal frame and floor of the structure are called platforms,

The purpose of counterweight is to make

Elevator internal structure rated load

Refers to the elevator load capacity specified in the design, which can be understood as the allowable load capacity of the manufacturer to ensure normal operation, in kilograms. It is the main basis for design and manufacture for manufacturers, and the main basis for choosing elevators for users, so it is the main parameter of elevators.

Rated speed of elevator internal structure

The rated speed refers to the operating speed of the elevator as specified in the design. It can also be understood as the elevator speed that the manufacturer guarantees normal operation. The unit is m / s. The rated speed is also the main basis for the design, manufacture and selection of the elevator, and it is also the main parameter of the elevator.

Elevator internal structure drag mode

Refers to the type of power used by the elevator. Can be divided into AC power drag, DC power drag, hydraulic drag.

Elevator internal structure car size

Refers to the internal and external dimensions of the car, expressed as "depth x width". The internal dimensions are determined by the ladder type and the rated load, and the external dimensions are related to the design of the hoistway.
