Segmented type counterweight system of whole-segment-traction multi-angle inclined-travel elevator

Abstract

The invention discloses a segmented type counterweight system of a whole-segment-traction multi-angle inclined-travel elevator. The segmented type counterweight system of the whole-segment-traction multi-angle inclined-travel elevator comprises multiple sets of counterweight connecting frames, steel wire rope clamping devices, counterweights and counterweight locating and locking devices, wherein the multiple sets of counterweight connecting frames, steel wire rope clamping devices, counterweights and counterweight locating and locking devices are arranged on all segments, arranged obliquely at constant angles, of a counterweight guide rail in a matched manner. The segmented type counterweight system of the whole-segment-traction multi-angle inclined-travel elevator is of a whole-segment type multi-counterweight structure. Each counterweight guide rail is provided with the respective counterweight. Counterweight balance of each segment of an elevator car guide rail is achieved in a front and back relay manner. When angle change is conducted once, bearing frames conduct disengagement of the counterweight connecting frame of a first segment of the counterweight guide rail and connection of the counterweight connecting frame of the second segment of the counterweight guide rail once. For the whole-segment-traction multi-angle inclined-travel elevators having various terrain requirements, the segmented type counterweight system can achieve segmented counterweight balance of an elevator car system according to different angle changes, and the segmented type counterweight system is particularly suitable for the inclined-travel elevator having the terrain requirement that the inclination angle is increased discontinuously or reduced discontinuously.

Description

technical field [0001] The invention relates to an elevator counterweight system, in particular to a segmented counterweight system for whole-section traction and multi-angle oblique elevators, belonging to the technical field of oblique elevators. Background technique [0002] An elevator is a kind of elevator powered by a motor. It is customary to use the elevator as a general term for vertical transportation in buildings regardless of its driving mode. As a modern transportation tool, it plays an important role in the transportation of high-rise buildings. As a branch of special elevator development, the elevator is mainly used to complete the lifting of some slope-shaped tracks. Its car runs along the inclined guide rail in the inclined shaft. It is a transportation equipment integrating sightseeing and transportation. After the house was moved to the mountain due to tension, the inclined elevator developed rapidly. Compared with the vertical traction elevator, the incli...

Problems solved by technology

[0005]1. Inclined elevators with traditional counterweight systems are only suitable for situations where the inclination angles of continuous uphill or continuous downhill gradually increase or decrease successively, In this case, the counterweight device can achieve a better counterweight effect by relying on its own weight; but for the situation that the inclination angle increases and decreases during the uphill or downhill process, that is, the inclination angle increases discontinuously or continuously decreases In this case, the counterweight device cannot achieve a good counterweight effect by relying solely on its own weight in this case, especially during the positive and negative conversion of the inclination angle. In the case of a negative angle, the counterweight device may even appear in a dangerous situation of falling sharply, and an additional brake device is often required to prevent the counterweight device from falling sharply;

[0006]2. The traditional counterweight system that connects the counterweight device and the car system through traction ropes and guide wheels is opposite to the inclined guide rail and the counterweight guide rail. In the case of a shorter length, better transmission and counterweight effects can be achieved; however, in the case of long inclined guide rails and counterweight guide rails with multiple continuous changing angles, the method of simply pulling the traction rope and a single The counterweight device often requires the electric drive system to provide sufficient pulling force, which not only causes the electric drive system to be bulky, but also causes the overall transmission efficiency to be low due to multiple continuously changing angles;

[0007]3. The traditional counterweight system usually uses a car system to pull a counterweight device, and the weight of the counterweight device is a rated value, that is, when the tilt angle changes In the process, the counterweight device with the same weight is used for different inclination angles. However, different inclination angles result in different vertical force components of the counterweight device. The moving speed of the compartment system is different, and the phenomenon of fast and slow is serious
