Description

Installation device for performing installation work in the elevator shaft {EQUIPMENT FOR INSTALLATION WORKS IN ELEVATOR SHAFT} The present invention relates to a mounting device that can be used to perform installation work in an elevator shaft of an elevator system, and more specifically, to a device for facilitating the exchange of tools used to perform installation work. Since multiple components must be installed at different locations within the elevator shaft, the manufacturing of the elevator system, and especially the assembly of the elevator system components that must be performed within the elevator shaft in a building, can entail great complexity and/or high costs. At this time, for example, the mounting steps used in the context of the assembly process to assemble components within the elevator shaft were generally performed by technicians or assembly personnel. Typically, for example, holes are drilled in the elevator shaft wall and screws pushed into these holes or bolts inserted into these holes are used to attach the components to the elevator shaft wall, so that a person moves to the location within the elevator shaft where the components are to be assembled and assembles the components at the desired location from there. A person may also use tools and/or machines for this purpose. Particularly in very long elevator systems, that is, so-called high-rise elevators that must overcome large height differences in high-rise buildings, the number of components to be installed in the elevator shaft may be very large, and thus the assembly work may entail significant assembly effort and costs. To solve these problems, US 11,703,823B discloses a method of performing assembly work using a robot arm 22 installed inside an assembly device 14 suspended in an elevator shaft. However, when tools used in assembly work utilizing such a device become worn out, there is a problem in that supplying and replacing tools is difficult because the assembly device is installed in a high-altitude elevator shaft. For example, drilling is essential to install fastening components such as screws on the elevator shaft walls for assembly work, but the drill bits used for this purpose become worn out from prolonged use and need to be replaced. To solve these problems, US 2023/0094665 discloses a method for replacing a drill tool housed in a drill chuck. In the first step, a worn drill tool assembled in a drill holder installed at the end of a robot arm is disassembled by a gripper formed on the side wall of the assembly device gripping the worn drill bit. In the second step, a drill holder installed at the end of the robot arm is removed and a gripping means is assembled, and then the spent drill bit installed on the gripper is grasped by the gripping means and moved to a magazine; In the third step, a new drill tool is grasped from a magazine using a gripping means and grasped by the gripper using a robot arm; The fourth step consists of removing the gripping means installed at the end of the robot arm, assembling the drill holder, and then attaching a new drill tool installed on the gripper means to the drill holder. Therefore, there is a cumbersome problem in that a complex device called a gripper and a gripper means is required to replace the worn-out drill tool, and the replacement work is also carried out in four steps.
