Multi-degree-of-freedom weak connection joint additionally provided with steel elevator shaft

Abstract

The invention discloses a multi-degree-of-freedom weak connection joint additionally provided with a steel elevator shaft. The multi-degree-of-freedom weak connection joint comprises a first mounting plate, wherein a plurality of first threaded holes are formed in the upper end of the first mounting plate; two mounting blocks are symmetrically and fixedly connected to the upper end of the first mounting plate; mounting grooves and placing grooves are formed in the front sides of the two mounting blocks; the opposite sides of the two placing grooves are communicated with the corresponding mounting grooves; limiting plates are arranged in the two mounting grooves correspondingly; first air springs are installed at the opposite sides of the two limiting plates correspondingly; and the two first air springs penetrate through the corresponding placing grooves correspondingly. The device is easy and fast to install, the use of screws is effectively reduced, through the design of the first air springs, second short springs, second air springs, second short springs and other devices, the influence on the device when connecting blocks are stressed can be effectively relieved, the service life of the device is prolonged, and the fixing effect of the device is improved through the design of expansion bolts.

Description

technical field [0001] The invention relates to the technical field of elevator steel shaft structures, in particular to a multi-degree-of-freedom weak connection node for adding elevator steel shafts. Background technique [0002] Elevator shaft, a vertical passage in a building for elevators to travel up and down, with a rectangular or square cross-section. Generally, one shaft is used by one elevator. In special cases, two or more elevators can be used side by side to share one shaft. In each There are door openings on the floor of the storey, and the shaft door can be installed. The elevator car and the guide rail on which the counterweight slides are installed in the hoistway, the buffer of the elevator car is installed in the bottom pit of the hoistway, and the motor and transmission machinery are mostly installed on the top of the hoistway; [0003] When installing the motor shaft, it is necessary to connect the elevator and other equipment with the shaft, so a conne...

AI Technical Summary

Problems solved by technology

[0003] When installing the motor well, it is necessary to connect the elevator and other equipment with the well, so a connecting device is required. Usually, only a simple connection using a connecting block and a bolt is used for the connection. This is a strong connection, although the fixing effect is better. However, after the elevator is used for a long time, the connecting device is deformed due to stress, which makes the service life of the device weak. Moreover, when ordinary bolts fix the connecting device on the wall of the hoistway, the fixing effect is not good. slipping outside, causing a safety hazard
