How Many Types Of Elevators Are There?
The basic classification methods of elevators are as follows.
1 classification by use
1.1 passenger lifts, designed for passengers, require perfect safety facilities and a certain kind of interior decoration.
1.2 freight elevators, designed primarily for the delivery of goods, usually accompanied by an elevator.
1.3 medical elevator, which is designed for the transport of beds, stretchers and medical vehicles, the car has long and narrow characteristics.
1.4 sundry elevator, for library, office building, hotel to transport books, documents, food and other designed elevators.
1.5 sightseeing elevator, the car wall is transparent, for passengers to use the elevator.
1.6 vehicle lift, used as an elevator for loading vehicles.
1.7 elevators for ships, elevators used on ships.
1.8 elevators for building construction, construction and maintenance.
1.9 other types of elevators, in addition to the above commonly used elevators, there are also special purpose elevators, such as cold storage elevators, explosion-proof elevators, mine elevators, power station elevators, and fire fighters, etc.
2. Classification by driving mode.
2.1 ac elevator and ac induction motor as the driving force. According to the method of drag, it can be divided into ac single speed, ac double speed, ac speed regulation, ac variable voltage frequency control, etc.
2.2 dc elevator, using dc motor as the driving force. The rated speed of such elevators is generally above 2.00m/s.
2.3 hydraulic elevator, generally using electric pump to drive liquid flow, the elevator of the car lift by plunger.
2.4 gear and rack elevator, the guide rail is processed into a rack, and the car is equipped with gear meshing with the rack, and the motor drives the gear to rotate and lift the elevator.
2.5 screw elevator, the direct roof of the plunger elevator processed into rectangular screw, with a thrust bearing large nut installed on the cylinder head, and then by the motor through reducer (or belt) drives the nut rotate, so that the screw jack-up capsules can rise or fall of the elevator.
2.6 linear motor drive elevator, its power source is linear motor.
In the early days of the elevator, the steam engine and internal combustion engine were used to drive the elevator directly.
3. Classification by speed
There is no strict speed classification of elevators, and our country is accustomed to classification by the following methods.
3.1 low-speed ladder, usually refers to an elevator that is lower than 1.00m/s.
3.2 medium speed ladder, usually refers to the speed between 1.00 ~ 2.00m/s.
3.3 high-speed ladder, usually refers to the elevator with a speed greater than 2.00m/s.
3.4 ultra-high speed, speed over 5.00m/s elevators.
With the continuous development of elevator technology, the elevator speed is higher and higher, and the speed limit of the difference between high, medium and low speed elevators is also increased.
According to the elevator, there is no driver classification.
4.1 there is a driver's elevator, which is operated by a full-time driver.
4.2 there is no driver's elevator, the passenger enters the elevator car, press the floor button that needs to go on the control panel, the elevator automatically runs to the destination floor, which has the function of collecting and selecting.
4.3 there is/no driver's elevator. This kind of elevator can change the control circuit, which is usually operated by passengers. If the passenger flow is large or necessary, it will be operated by the driver.
5. Classification by manipulation control.
5.1 handle switch control, the elevator driver controls the handle switch in the cage to realize the starting, ascending, descending, flat and stop operation of the elevator.
5.2 button control elevator: it is a simple automatic control elevator, which has automatic level function. It is common to control two kinds of control modes, including external button control and inner button control.
5.3 signal control elevator, which is an automatic control degree with a driver's elevator. In addition to automatic leveling, automatic door opening function, there are cage command registration, floor call registration, automatic stop, stop and automatic reversing.
5.4 collection control elevator is a fully automatic control elevator developed on the basis of signal control. The main difference between signal control and signal control is that it can be operated without driver.
5.5 parallel control elevator, 2 ~ 3 elevator control lines are connected in parallel to carry out logic control, and the common floor call button, the elevator itself has the collection function.
5.6 group control elevator is controlled by microcomputer and unified dispatching multiple sets of centralized elevators. The group control has the control of ladder group and intelligent control of echelon.
6. Other classification methods.
6.1 according to the computer room position classification, has a room at the top of the shaft (room) on the elevator, machine room at the bottom of the shaft side (room) under the elevator, and have room inside the shaft of the elevator, machineroomless).
6.2 according to the size classification of the car, the abstract words such as "small" and "super large" are often used.
In addition, there is a double car elevator and so on.
7.1 ramp elevator, the cage is running along the inclined guide rail in the sloping tunnel, which is a transportation equipment integrating sightseeing and transportation. In particular, because of the land tension and move the residence to the mountainous area, the slope elevator develops rapidly.
7.2 the elevator is used in the 3d parking lot, and different types of elevators can be selected according to different parking lots.
7.3 construction elevator, is a way of using meshing gear and rack (including pin gear transmission and chain drive, or use rope hoisting), make the hanging basket for vertical or tilting movement of the machine, used to transport personnel or material, mainly used in construction and maintenance. It can also serve as a long - term vertical transport machinery for warehouses, docks, docks, towers, and tall chimneys.
