Description

Technical Field

[0001] The present invention relates to an elevator installation device, in particular to an elevator guide rail installation device. Background Art

[0002] As a means of transportation in buildings, elevators are being used more and more with the development of society. Elevator installation projects have become a huge industry. Elevator installation generally includes the following: installing the elevator's lifting and traction device and control system in the machine room; installing the elevator car, counterweight, guide rails, cables, floor control devices and protective devices in the concrete hoistway; and installing the hall door, display device and floor call device at the entrance. The construction of an elevator in a concrete hoistway generally requires the installation of four guide rails, including two left and right main rails for guiding the elevator car's lifting and lowering, and two auxiliary guide rails for guiding the counterweights that balance the weight of the elevator car; and the installation of several hall door thresholds and door frames for entering and exiting the elevator. The installation and construction of guide rails and door frames require prior plumb line layout, and then the basic fixings are installed based on the plumb line layout. Among them, the installation of door frames requires the installation of expansion screws on the wall to fix the bottom sill, upper sill, small door frames and other basic fixings; the installation of guide rails requires the installation of guide rail brackets and basic fixings such as the bottom code (usually angle iron, commonly known as the bottom code, the same below) used to fix the guide rail bracket to the wall, and then the guide rails are installed, docked and adjusted.

[0003] During the installation of elevator guide rails, due to the limited depth of the concrete shaft, the four guide rails that need to be installed need to be spliced together from multiple rails. After the guide rails are installed, the lifting platform carrying the construction workers rises to the upper end of the guide rail. The construction workers then align the bottom of the next guide rail with the top of the previous guide rail. At this time, the position and posture of the next guide rail need to be calibrated to ensure that the two are perfectly aligned. However, the existing calibration method is manual visual calibration by the construction workers. This manual calibration method is not only inefficient, but also requires a high level of installation technician proficiency, is labor-intensive, and has low construction precision.
