Elevator counterweight device with low-height anti-seismic design

Abstract

The invention discloses an elevator counterweight device with low-height anti-seismic design. The elevator counterweight device comprises counterweight vertical beams which are oppositely arranged, wherein an upper connecting plate for connecting the two counterweight vertical beams is arranged at the top of the counterweight vertical beams, a guide wheel is arranged in the center of the upper connecting plate, hanging plates are arranged on the two sides of the guide wheel, lower rope blocking rods are arranged at the bottom ends of the hanging plates, and the two lower rope blocking rods are located on the inclined lower portion of the guide wheel correspondingly; and a lower connecting plate for connecting the two counterweight vertical beams is arranged at the bottom of the counterweight vertical beams, stacked counterweight iron is arranged on the lower connecting plate, each counterweight vertical beam comprises a base part arranged in the length direction and side walls perpendicular to the two sides of the base part, and the two ends of the counterweight iron are embedded into the counterweight vertical beams. According to the elevator counterweight device with the low-height anti-seismic design, when a counterweight guide shoe loses efficacy in an earthquake, the counterweight device can be limited on a guide rail through an anti-falling device, and the damage degree of the earthquake to the elevator counterweight device is reduced.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator counterweight device with a low-height anti-seismic design. Background technique [0002] For traction elevators, the counterweight system is used to balance the weight of the car system and is an important component to ensure traction. With the increasing pressure of elevator manufacturing costs, the counterweights in the counterweight system are mostly made of "cement". Compared with "cast iron" counterweights, "cement" counterweights are larger in volume and higher in overall height. Cause the total height of the whole counterweight system to increase. The increase of the total height of the counterweight system will affect the height of the top floor of the building and the depth of the pit, which will increase the construction cost. Therefore, it is necessary to develop a low-height counterweight device. At the same time, due to the reports of earthquake acci...

Problems solved by technology

With the increasing pressure of elevator manufacturing costs, the counterweights in the counterweight system are mostly made of "cement". Compared with "cast iron" counterweights, "cement" counterweights are larger in volume and higher in overall height. Resulting in an increase in the overall height of the entire counterweight system

However, the increase in the total height of the counterweight system will affect the height of the top floor of the building and the depth of the pit, which will increase the construction cost. Therefore, it is necessary to develop a low-height counterweight device.

At the same time, due to the reports of earthquake accidents in recent years, the damage of elevators is more common. As an important part of the elevator, the counterweight device is usually not specially designed for anti-shock of the counterweight device. When an earthquake occurs, the elevator The derailment of the counterweight device is relatively common, so the anti-seismic design of the elevator counterweight device is very meaningful for the actual use of the elevator
