Problems solved by technology

When the elevator with the same guide rail unevenness is at different operating speeds and / or different natural frequencies, the vibrations will be different. The guide components that can reduce the horizontal vibration of the elevator during the elevator’s constant speed stage may be parallel during the acceleration and deceleration stage of the elevator. The same vibration reduction effect cannot be achieved. The guide assembly that can reduce the vibration of the elevator in the horizontal direction when the elevator is fully loaded may not achieve the same vibration reduction effect when the elevator is unloaded

Embodiment 1

[0073] This embodiment provides an elevator operation control method, which is applied to an elevator. The elevator is provided with multiple guide assemblies. In this embodiment, the one-side moving part of the guide assembly has two guide parts, and the guide parts are rollers. The working surface of the guide rail 1 is in contact with the rollers. like Figure 7 The distance between the two rollers shown is denoted as L(t), and the distance between the two rollers 101 and 102 can be adjusted accordingly by controlling the corresponding movement mechanism on the guide assembly. When the working surface of the guide rail is uneven, the upper and lower two rollers will pass through the unevenness in turn, and each roller will overcome the elastic force of the spring part and move along the horizontal direction. During this process, the elastic force of the spring part will act on the elevator body , causing it to vibrate. For an unevenness on the working surface of the guide...

Embodiment 2

[0085] like Figure 8 As shown, in this embodiment, the one-side moving part of the guiding device has three guiding parts, that is, three rollers. The working surface of the guide rail is in contact with the roller 301 . The top roller is connected to the primary connecting rod 303 through the roller shaft 302, the middle roller and the bottom roller are connected to the secondary connecting rod 303' through the roller shaft 302, and the secondary connecting rod 303' is connected to the secondary connecting rod shaft 304' at its center Connect with the primary connecting rod 303. The primary connecting rod 303 is connected with the push rod 305 through the primary connecting rod shaft 304 . The distance from the connecting rod shaft 304 to the roller shaft 302 of the top roller is twice the distance from the connecting rod shaft 304 to the secondary connecting rod shaft 304', thus ensuring that the three rollers 301 are subjected to the same normal force on the working surf...

Embodiment 3

[0094]This embodiment discloses an elevator operation control system, which is applied to elevators, where multiple guide assemblies are provided in the elevator, each guide assembly includes a plurality of guide parts, and the control system includes: a first acquisition module 1 for acquiring The running speed of the elevator body; the second acquisition module 2 is used to obtain the natural frequency of the elevator body; the processing module 3 is connected to the first acquisition module 1 and the second acquisition module 2, and is used to obtain the best frequency according to the operating speed and natural frequency processing Distance value; the control module 4 is connected to the processing module 3 and the guide assembly, and is used to adjust the distance between the guide parts in each guide assembly according to the optimal distance value. The formulas that the processing module 3 is based on when there are two guiding parts and the formulas that are based on w...

Abstract

The invention discloses an elevator operation control method and system, and belongs to the technical field of elevators. The method comprises the steps: S1, obtaining a running speed of an elevator body; S2, acquiring a natural frequency of the elevator body; S3, processing according to the running speed and the natural frequency to obtain an optimal distance value; and S4, adjusting the distancebetween guide parts in each guide assembly according to the optimal distance value. The system comprises a first acquisition module, a second acquisition module, a processing module and a control module. The elevator operation control method and system have the beneficial effects that the distance between rollers of a roller guide shoe is dynamically adjusted by detecting the current running speed and the natural frequency of the elevator body in real time, so that the vibration in the horizontal direction caused by guide rail defects on the elevator body in different moving states is greatlyweakened and even eliminated.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator operation control method and system. Background technique [0002] When the elevator moves in the vertical direction, it usually needs a corresponding guide device to ensure the comfort of the user. The guide rails in the guide device are usually spliced, and there will inevitably be steps out of tolerance at the joints of the guide rails, and Since the working surface of the guide rail often has problems such as local defects, local distortions and excessive spacing, this will further aggravate the vibration of the elevator car in the horizontal direction. With the continuous increase of building floors in recent years, the running distance and running speed of the supporting elevators are increasing accordingly, and the guide rail problem has an increasing impact on the vibration of the elevator car. [0003] The elevator is usually divided into three stages duri...
