Introduction of small household elevators and their design notes

Design notes First of all, you need to determine the shaft and position of small household elevators, and the combination of stairs is the best solution. Determine its function and the construction of safety facilities, which is mainly highlighted in the design of the door and when urgent problems arise.

The elderly and children do not have the professional knowledge and self-protection awareness of using home villa elevators, so more attention should be paid to the safety and convenience of home villa elevators in the design.

Installation location: The installation position of small household elevators needs to take into account the needs and safety of users, and cannot be installed at will. 2 Maintenance: Small household elevators need to be maintained regularly to ensure the normal operation and safety of the elevator.

Notes on the installation of household simple elevators Well position and space: The position and space of the well determines the size of the elevator and door opening. It is a good plan to install the elevator in the middle of the stairs and combine it with the stairs. ( 1). The middle of the stairs, the corner of the wall, and the external hanging are all acceptable, and it is better to be in the middle without blocking the passage.

The installation of small elevators for villas needs to pay attention to the following points: the construction of elevator shafts The construction of elevator shafts needs to be carried out in strict accordance with the design requirements. The shaft wall should be made of fireproof, moisture-proof and earthquake-proof materials, and the roof of the shaft should be made of waterproof materials. Installation of elevator door The installation of elevator door needs to pay attention to the position and size of the door.

Well, next, I will introduce the precautions for the design of home villa elevators. The position and space of the well. The middle of the stairs, the corner of the wall, and the plug-in are all acceptable, and it is better to be in the middle without blocking the passage.Push the width of the wellway back with the width of the door opening, and push back the height of the car with the height of the top floor.

How to design an elevator system for a 300-story skyscraper?

One way to solve this problem is to make the building flat.

More idealThe plan is that 2 shuttle service elevators go directly from the underground to the lobby, and the other four service elevators run from the air lobby through the guest room floor to the roof. The service floor of the podium elevator is small, and the flow can be diverted by setting up a sufficient number of escalators (the escalator carrying capacity can reach 9,000 people/hour) without too much discussion.

Principles of elevator configuration: estimate the number of users of the building, determine the 5-minute carrying capacity requirements, and determine the escalator waiting time requirements.

The first thing that needs to be considered is the determination of the distribution and transformation system and the emergency power supply system and the access of the self-provided power supply system, including the establishment of the power supply voltage level, the establishment of the normal power supply system, the selection of self-provided emergency power supply system equipment, and the reasonable and effective access of the self-provided emergency power supply system to the main system, etc. All questions need to be paid attention to.

Evelator is the core class of the whole elevator system, which mainly has the following attributes and methods: Attributes: Method: First of all, we assume that we press the 6th floor first, and then press the 2nd layer after reaching the 3rd floor. If you put 2 in a queue, you can't take the largest or the smallest.

The floor that restricts the elevator to reach: please ask the elevator maintenance company to set it in the system. Install electronic clock control on the call button signal inside and outside the elevator.

Design and debugging of three-story elevator PLC control system

Preliminary mastery of the application of PLC, program design method, and external line connection Design topic: automatic control action of three-story elevator Requirements: Figure 4-8 isSchematic diagram of the three-story elevator, the top and bottom of the elevator are controlled by a motor: forward rotation (up), reverse (fall).

There is a life problem, take it seriously. The elevator program is said to be simple, but it is very complicated to use in practice. To consider the number of elevators and the usage of the house, we need to consider a lot and deal with it on a case-by-case case. Besides, I don't know which PLC you use. I can't give it to you either. More importantly, please take the elevator seriously about people's lives.

Through the simulation of engineering examples, master the programming and program debugging methods of PLC. Be more familiar with the I/O connection of PLC. Familiar with the programming method of three-story elevators using button control inside and outside the car.

Design an efficient, safe and cheap one; it can be personalized and can be used in commercial office buildings,A popular elevator control system that plays a significant role in administrative buildings, small and medium-sized hotels and residential apartments.

Graduation thesis on the design of PLC-based elevator control system

1. PLC control generally has the characteristics of high reliability, easy operation, maintenance, simple programming, strong flexibility and so on. This design is realized by PLC control, studying and analyzing the logical relationship of the elevator, and then realizing control.

2. The third part is hardware design, and this part includes the frequency converter. Selection and parameter design, PLC selection, the main functions implemented by the system, and the allocation of I/O interfaces. Because the cost of the elevator professional frequency converter is too high, in order to save costs, the general frequency converter is chosen.

3. The control system is the soul of the whole production line and plays a commanding role for the whole production line. Once the control system fails, the light one will affect the continuation of the production line, and the heavy one will even cause personal safety accidents, which will cause great losses to the enterprise.
