Description

Technical Field

[0001] This application relates to an elevator system. Background Art

[0002] During the installation of an elevator system, a traction hoist, such as a Tirak, is often required, which is generally installed on the top beam of the elevator system. However, machines such as Tirak are usually located at a great distance from the top of the car, for example, more than 1400 millimeters. Therefore, if an operator wants to stand on the top of the car for installation operations, they may not be able to reach the Tirak machine. Thus, an additional work platform is often required for the operator to stand on to install the remaining guide rails, etc.

[0003] Therefore, there is a need for an elevator system that can use the top of the car as a work platform, thus saving the need for an additional work platform. Summary of the Invention

[0004] This application provides an elevator system, including: columns that extend vertically along the elevator shaft and accommodate guide rails; guide shoes for engaging the guide rails, characterized in that during the installation of the elevator system via a traction device, the guide shoes are temporarily installed on the columns via fastening devices to engage the guide rails.

[0005] Advantageously, the fastening device includes: a first plate that is fixedly installed on the column and extends parallel to the column; a second plate that extends obliquely from the first plate, and the guide shoe is fixedly installed on the second plate.

[0006] Advantageously, the second plate extends from the first plate in a direction perpendicular to the wall of the elevator shaft.

[0007] Advantageously, the first plate is fixedly installed on the column by bolts and abuts against the column.

[0008] Advantageously, the second plate includes one or more holes, and the guide shoe is fixedly installed on the second plate by inserting bolts into each hole.

[0009] Advantageously, the holes are oblong holes, and the shape of the oblong holes is designed to extend perpendicular to the extension direction of the second plate, so that the position of the guide shoe can be adjusted when installing the guide shoe.

[0010] Advantageously, the elevator system further includes a top beam installed on the column, and the top beam can be installed on the column at a first position and a second position under the action of the traction device. The first position corresponds to the final position of the top beam after the elevator is installed, and the distance between the second position and the top of the elevator car is less than the distance between the first position and the top of the elevator car.

[0011] Advantageously, the column includes a first mounting feature and a second mounting feature, the first mounting feature corresponding to a first position of the top beam to fix the top beam at the first position, and the second mounting feature corresponding to a second position of the top beam to fix the top beam at the second position.

[0025] Figure 1 A perspective view showing a part of an elevator system, the elevator system has been installed and is in a usable state. At this time, the top beam 4 is in the first position, that is, the final position, and the guide shoe 1 remains fixedly installed on the column and can engage with a guide rail (not shown) inside the column 2.

[0026] Figure 2 Showing that during the installation of the elevator system, the top beam 4 moves downward to the second position, and the guide shoe 1 is installed on the column and can engage with the guide rail inside the column. Thus, the top beam moves downward to the second position, reducing the distance between the top beam and the elevator car, thereby reducing the distance between a traction hoist 5 such as a Tirak and the elevator car, enabling the operator to use the top of the car as a working platform. Since the guide shoe is fixedly installed on the column instead of the top beam, the guide shoe can still engage with the guide rail when the top beam moves downward to the second position.

[0027] The first position of the top beam is higher than the second position, and the second position corresponds to the position between the final position of the top beam and the top of the elevator car during elevator installation.

[0028] The column 2 includes a first mounting feature 21 and a second mounting feature 22. The first mounting feature 21 corresponds to a first position of the top beam to fix the top beam at the first position, and the second mounting feature 22 corresponds to a second position of the top beam to fix the top beam at the second position. The first mounting feature and the second mounting feature are in the form of holes, as Figure 7 shown. Figure 7 Only a schematic number of the first mounting features and the second mounting features are shown schematically. Those skilled in the art should understand that the position and number of the first mounting feature 21 can be selected as needed as long as they can satisfy the final position of the top beam during the use of the elevator system, and the position and number of the second mounting feature 22 can also be selected as needed as long as they can satisfy the desired second position of the top beam during the installation of the elevator system.

[0029] Figure 3 , 4 Figures 4 and 5 show how the guide shoe 1 is mounted to the column 2 via the fastening device 3. The fastening device includes a first plate 31 which is fixedly mounted to the column, for example by bolts, and extends parallel to the column 2, that is, extends vertically parallel to the elevator shaft. The first plate 31 is flat to abut against the side surface of the column. The second plate 32 of the fastening device 3 extends obliquely from the first plate 31, preferably extends vertically, and the guide shoe 1 is fixedly mounted to the second plate 32.

[0030] The second plate 32 includes one or more holes 33, and the guide shoe 1 is fixedly mounted to the second plate 32 by inserting bolts into each hole. Preferably, the holes are oblong holes, and the shape of the oblong holes is designed to extend perpendicular to the extending direction of the second plate 32, so that the position of the guide shoe can be adjusted in the direction perpendicular to the extending direction of the second plate when installing the guide shoe.

[0031] In the drawings, the guide shoe 1 includes a mounting plate 11, and the mounting plate also includes one or more oblong holes 12. The extending direction of the oblong holes of the mounting plate 11 is perpendicular to the extending direction of the oblong holes of the second plate. Bolts pass through the oblong holes of the mounting plate and the second plate respectively, thereby mounting the guide shoe to the second plate. In this way, the position of the guide shoe can be adjusted in two directions. However, those skilled in the art should understand that the type of the guide shoe 1 is not important for this application, and the guide shoe can be any suitable type of guide shoe as long as it is mounted to the second plate.

[0032] The fastening device further includes an inclined plate 34 connected between the first plate 31 and the second plate 32, and the inclined plate can act as a reinforcing rib.

[0033] With the elevator system of the present application, it is possible to lower the position of the top beam during the installation of the elevator system, use the top of the elevator car as a working platform, saving the need for an additional working platform. At the same time, the guide shoes are installed on the columns instead of the top beam, and the guide shoes can still be engaged with the guide rails without interfering with the functions of the guide shoes.

[0034] Although the present invention has been described in the specification and illustrated in the drawings on the basis of referring to various embodiments, those skilled in the art can understand that the above embodiments are only preferred embodiments. Some technical features in the embodiments may not be necessary for solving specific technical problems, so these technical features can be absent or omitted without affecting the solution of the technical problems or the formation of the technical solutions. Moreover, the features, elements, and / or functions of one embodiment can be appropriately combined, combined, or coordinated with the features, elements, and / or functions of one or more other embodiments, unless the combination, combination, or coordination is clearly infeasible.
