Description

Safe, simple and fast installation suitable for low-floor elevator device and application component

This creation is based on the characteristics of low wear and no noise when the ball screw and the ball sleeve are rotating with each other. The motor with low horsepower output uses the slope of the screw spiral to enable the elevator car to use the configured tooth sprocket. Sleeve set, to receive the power of rotation driven by the chain, stable and safe, the internal circulation type steel ball rises or falls according to the slope of the screw, and uses the physical characteristics of saving energy due to the gradient climbing, so that the motor's required horsepower output is saved And through the configuration of the main drive chain, when any chain is broken, the overall mechanism runs as usual, and then the controllable needle roller one-way clutch is applied to stop at any time on the predetermined floor or when there is a sudden power failure. Both can forcibly stop the rotation operation with the mechanism of the needle roller interference force to stop the elevator car from sliding down. When a power outage occurs and the elevator is not stopped at a predetermined position on the upper or lower floor, the internal lever handle of the elevator car is pulled at this time to interlock The needle in the one-way clutch is out of the interference limit, that is, it can slip back to the nearest lower floor and stay exactly at the predetermined position on the next floor. , Touch the dial back piece, one-way clutch positioned reply lockout, is not a true safety of trapped elevator design.

As shown in Figure 20, the conventional elevator architecture uses steel cables to lift the elevator car up and down. It has the ability to run at high speed, but a large and expensive main drive motor must be installed on the top floor, civil engineering works of shaft tracks and wells need to be set up, counterweight devices need to be equipped with anti-fall devices, and regular inspection and maintenance are required. Clips, guide shoes and rails, and replacement of consumable steel cables, must be equipped with generator sets and regular maintenance oil maintenance or large-capacity uninterruptible system battery maintenance.

Known on the market are steel cable elevators as the mainstream, which runs fast, has smooth and safe control, and is only heard when the elevator is trapped. Because the system is mainly controlled and driven by electricity, the overall emergency power generation system or continuous power The system is expensive and complicated, damage to electronic control devices is prone to moisture loss, maintenance and standby costs are very high, and the installation time is very long.

The invention provides a ball-screw elevator with low-floor, safe, comfortable, stable, and cheap and fast installation. The elevator has quiet and ultra-safety characteristics. The running speed is about 1/3 slower, and the overall installation cost only requires ordinary steel cables. 1/5 ~ 1/2 of the elevator, the installation time only needs 1/30 ~ 1/10 of the ordinary steel cable elevator, has multiple safety mechanism protection, simple mechanical structure protection device, ultra low maintenance cost, suitable for construction Installation on low floors.

The invention can be quickly installed, and provides a rapid construction starting from the first floor of the bottom. It adopts standard components for installation. After the foundation of the bottom floor is screwed, the elevator can be manually adjusted to lift. Exterior decoration board and high-level extension ball screw on the top of the elevator, as well as the control line plugs on each floor, plug in and install floor limit switches. Two people construct and assemble the elevator (excluding civil engineering). The fastest can be built on the first to third floors a day Time consuming during construction The problem is too long.

The invention provides a mechanism-type safety control without electric power, without the need for a battery of an uninterruptible power system or an emergency generator, that is, a controllable one-way clutch mechanism, which is installed on a screw sleeve and connected to an elevator car transmission structure. During normal up-and-down operation, once a predetermined floor is reached and power is no longer transmitted, the one-way clutch instantly locks to prevent downward movement, and synchronously ensures that the elevator car can pass immediately in case of sudden power failure or power failure The one-way clutch locks without slipping, and provides elevator passengers with the ability to operate inside the elevator car. The one-way clutch can be opened and closed by pulling on the connecting rod, so that the elevator car can be easily controlled by its own weight via the screw slope and motor The reduction ratio of the reduction gear is limited to gently descend to the next lower floor, allowing passengers to get out of the elevator smoothly and safely. There is no need to spend panic and helpless waiting time before being rescued when an elevator accident occurs. When he was rescued, he had to embarrassedly climb out of the elevator.

The present invention provides a multi-directional power transmission safety architecture. Generally, the most feared part of an elevator car is a broken steel cable, which causes the car to fall or lose power transmission and slide. It is positioned at any position by the safety gear and cannot enter and exit the elevator smoothly. The transmission chain provided does not rule out the occurrence of breakage due to the service life or any other reasons, but the motor of the present invention transmits power to each of the surrounding toothed sprocket sleeves. The chains are synchronized with the turning, and the action is completed ascending or descending. When any one of the chains is broken, any remaining chain can also provide 100% of the power transmitted by the same motor, which can avoid the chain that transmits power. The break caused the embarrassment of the occupants in the elevator.

The invention provides a smooth and comfortable suspension structure. A suspension spring is installed between the elevator car and each brake sleeve, which can provide a comfortable seat feeling in the elevator car, and can avoid the occurrence of the problem during startup and instant stop due to any reason. Vibrations cause discomfort.

The invention provides single and double spiral ball screws and matching sleeves, which are suitable for low floor applications with light and heavy loads.

The invention provides a light-load elevator with medium to high floors (about 6 to 7 floors), which is operated by ball single or double spiral screws, and the other two are changed into ball linear guide columns, which are used to construct buildings and straight lines on each floor. The guide pillars are locked indirectly to each other, which strengthens the support of the guide pillars to the lateral lateral displacement force of the earthquake when the elevator car encounters an earthquake.
