Safe transmission construction elevator

Abstract

The invention provides a safe transmission construction elevator. The elevator comprises a lift car, a manual control device, guide rails, racks, a power device, a control system module, and a monitoring system module. The power device provides lifting power for the lift car, the manual control device controls the power device through the system control module, and controls the lift car to lift, the control system module and the monitoring system module are arranged on the top of the lift car and are connected, a fixing frame is included and fixes the power device to the rear portion of the lift car, the two sides of the fixing frame are each provided with a rotation arc wheel, the two sides of each arc wheel are each provided with one guide rail and one rack connected with the arc wheel,one sides of the racks are connected with the arc wheels, one sides of the racks are connected with the power device, the power device is further provided with two brake devices located on the outer side of the fixing frame, and the power device of a one-way transmission structure of a one-way overrun clutch. The construction elevator is long in service life and good in safety.

Description

[0001] The patent application for the present invention is a divisional application. The patent number of the original case is 201710924087.5, and the application date is September 30, 2017. The name of the invention is a construction elevator with safe transmission. technical field [0002] The invention relates to a construction machine, in particular to a construction elevator with safe transmission. Background technique [0003] Construction elevators play an important role in various projects, which can speed up the progress of the project and reduce the labor intensity of workers. But the problem that occurs thereupon is the generation of the accident of construction elevator in the on-the-spot construction process, and wherein main cause is because the transmission failure of elevator causes. The current construction elevators mainly have cable transmission and worm gear transmission. As time goes by during operation, the cables and gears will age and wear, which wil...

AI Technical Summary

Problems solved by technology

However, the problem that followed was the occurrence of construction elevator accidents during the on-site construction process. The main reason was the failure of the transmission of the elevator.

The current construction elevators mainly have cable transmission and worm gear transmission. During the operation process, as time goes by, the cables and gears will age and wear, which will lead to accidents.

[0004] Now some enterprises have begun to use the transmission structure of rack and pinion, but the tooth shape wears seriously in the actual operation process, and the rack and pinion of construction elevators will wear out if they are used for too long, and the gears need to be replaced frequently, resulting in an increase in maintenance costs. ;When the installation is not well adjusted, the deformation of the cage during use, the displacement of the rollers, etc. cause the meshing of the rack and pinion to be too loose, too tight or the contact area changes, which increases the risk factor of operation
