Elevator shaft perpendicularity detection device

Abstract

The invention discloses a verticality detection device for an elevator shaft, which comprises a load-bearing car body, a rotating pedestal, a guide column, a lifting slider, a horizontal support, a pay-off mechanism and a suspension measuring device. The middle part of the upper end of the load-bearing car body is welded with A motor is installed in the fixed base, the output end of the motor is connected to the rotating shaft, the upper end of the rotating shaft is welded with a limit turntable, and the upper part of the limit turntable is welded with a rotating pedestal; the upper end of the rotating pedestal is welded with a guide column, guiding The side of the column slides with a lifting slider, the bottom of the lifting slider is installed with a lifting cylinder, the lifting cylinder is fixed on the rotating pedestal, and the top of the vertical telescopic rod of the lifting cylinder is welded to the lifting slider; it is convenient to adjust the position of the suspension measuring device , which is convenient for laying out or winding the traction line. The laser emitting head emits a laser beam from the laser beam channel downward. The laser beam channel in the counterweight lead pendant is vertically downward, and the laser beam is irradiated vertically downward, which is convenient for elevator detection. verticality of the well.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a verticality detection device for an elevator shaft. Background technique [0002] With the construction of urbanization, there are more and more high-rise buildings. At the same time, high-rise buildings need to be equipped with elevators for daily use. Therefore, in the process of building construction, it is necessary to reserve an elevator shaft for the installation of elevator equipment. For the construction of the elevator shaft, it is necessary to maintain strict verticality to facilitate the installation of elevator tracks and counterweights on the shaft wall of the elevator shaft later. track to ensure the safe operation of the elevator. At present, in the construction of the elevator shaft, in order to ensure its verticality, the measurement is usually carried out by hanging the lead pendant with a simple rope. First, the setting stability of the lead p...

Problems solved by technology

At present, in the construction of the elevator shaft, in order to ensure its verticality, the measurement is usually carried out by hanging the lead pendant with a simple rope. First, the setting stability of the lead pendant is poor. Complicated and cumbersome, the lead pendant is easy to slip off and fall, and there are certain construction safety hazards. In addition, it is difficult to take up and release the lead pendant. People use the line above the lead pendant to detect the verticality of the elevator shaft with a limited height. The verticality of the elevator shaft below cannot be detected
