[0002] The construction elevator is installed before use. The elevator used in construction sites is also called a lifting cage. The installation process of the elevator, especially the installation of the guide wheels on the elevator, is relatively difficult. The existing method of installing the guide wheels of the elevator is to hoist the elevator to one side of the guide rail or directly place the elevator or cage on the ground on one side of the guide rail, fix the guide wheel on the elevator or cage, and install the guide wheel so that the guide wheel and the guide roller are parallel in the vertical direction. The hoisting method cannot always keep the elevator or cage stable, and the flatness of the film on the construction site cannot be guaranteed. At the same time, the guide wheel is fixed individually, which not only slows down the installation speed of the guide wheel, but also easily causes deviations in the parallelism between multiple guide wheels and the guide rail, resulting in unstable operation of the elevator or lifting cage, vibration, and affecting the safety of the elevator or cage.

A groove 14 is provided on the right end surface of the rod 8, a fixing plate 15 is provided in the mounting hole 61, an internal thread 16 is provided on the right side of the inner wall surface of the mounting hole 61, an external thread 17 is provided on the surface of the fixing plate 15, a limiting ring 18 is provided on the left end of the fixing plate 15, and a nut 19 is provided on the right end of the fixing plate 15. When the cage 1 is installed, the guide wheel 3 is flush with the guide rail, the threaded rod 8 is rotated, and a threaded hole 13 matching the threaded rod 8 is provided on the mounting shaft 9. During the rotation of the threaded rod 8, the mounting shaft 9 moves and drives the guide wheel 3 to move, so that the guide wheel 9 is stuck on the guide rail 2, and the guide wheel 3 is quickly moved. The cage 1 can be quickly installed on the guide rail 2. After the guide wheel 3 is installed, the fixing plate 15 is installed into the mounting hole 61. The external thread 17 provided on the surface of the fixing plate 15 matches the internal thread 16 provided on the inner wall of the mounting hole 61. Before installing the fixing plate 15, thread glue is applied to the external thread 17 provided on the fixing plate 15. The fixing plate 15 is installed. A tool (such as a wrench) is used to rotate the nut 19 provided on the right end of the fixing plate 15. The nut 19 drives the fixing plate 15 to rotate. The rotation of the fixing plate 15 will drive the limit ring 18 to continuously move toward the center of the mounting hole 61. , when the limit ring 18 contacts the inclined surface set at the right end of the threaded rod 8, tighten the nut 19 to increase the pressure between the limit ring 18 and the inclined surface at the right end of the threaded rod 8, thereby increasing the friction between the limit ring 18 and the threaded rod 8, and fixing the threaded rod 8 to prevent the threaded rod 8 from loosening during the use of the cage 1, resulting in an increase in the distance between the guide wheel 3 and the guide rail 2, thereby reducing the safety of the cage 1. Disassemble the cage, rotate the nut 19 in the reverse direction to remove the fixing plate 15, and use a tool to rotate the threaded rod 8 in the reverse direction to keep the guide wheel 3 away from the guide rail 2, thereby completing the quick disassembly of the cage.

[0018] The installation shaft 9 is provided with a guide hole 12 and a threaded hole 13. The guide hole 12 cooperates with the guide rod 11, and the threaded hole 13 cooperates with the threaded rod 8. The threaded rod 8 drives the installation shaft 9 to move during rotation.

After the limiting ring 18 presses against the inclined surface provided on the threaded rod 8, the friction between the limiting ring 18 and the threaded rod 8 is increased by increasing the pressure between the limiting ring 8 and the inclined surface of the threaded rod 8, so that the limiting ring 8 fixes the threaded rod 8;

[0021] The external threads 17 provided on the surface of the fixing plate 15 match with the internal threads 16 provided on the inner wall surface of the mounting hole 61 , and the fixing plate 15 is installed in the mounting hole 61 through the matching of the external threads 17 and the internal threads 16 .

[0022] Working principle: When the cage 1 is installed, the guide wheel 3 is flush with the guide rail, and the threaded rod 8 is rotated. A threaded hole 13 matching the threaded rod 8 is set on the installation shaft 9. The groove 14 set on the right end of the threaded rod 8 is a regular hexagon, which is convenient for using the inner hexagon to rotate the threaded rod 8. During the rotation of the threaded rod 8, the installation shaft 9 moves and drives the guide wheel 3 to move, so that the guide wheel 9 is stuck on the guide rail 2, and the guide wheel 3 is quickly installed, so that the cage 1 is quickly installed on the guide rail 2. After the guide wheel 3 is installed, the fixing plate 15 is installed into the installation hole 61. The external thread 17 set on the surface of the fixing plate 15 and the internal thread 16 set on the inner wall of the installation hole 61 match. Before the fixing plate 15 is installed, Apply thread glue on the external thread 17 set on 15, install the fixing plate 15, use a tool (such as a wrench) to rotate the nut 19 set on the right end of the fixing plate 15, the nut 19 drives the fixing plate 15 to rotate, and the rotation of the fixing plate 15 will drive the limiting ring 18 to continuously move toward the center of the mounting hole 61. When the limiting ring 18 contacts the inclined surface set on the right end of the threaded rod 8, tighten the nut 19 to increase the pressure between the limiting ring 18 and the inclined surface on the right end of the threaded rod 8, thereby increasing the friction between the limiting ring 18 and the threaded rod 8, and fixing the threaded rod 8 to prevent the threaded rod 8 from loosening during the use of the cage 1, resulting in an increase in the distance between the guide wheel 3 and the guide rail 2, thereby reducing the safety of the cage 1.
