Abstract

This utility model relates to the field of support adjusters, and discloses a support adjuster for elevator maintenance, including an adjustment component and a support component. The support component is provided at the upper end of the adjustment component. The adjustment component includes a base plate and two connecting blocks. Support legs are fixedly connected to the four corners of the lower surface of the base plate. Two grooves are respectively formed on both sides of the upper surface of the base plate. A bidirectional threaded rod is rotatably connected to the middle of the inner wall of the front end of one groove, and a guide rod is fixedly connected to the middle of the inner wall of the front end and the inner wall of the rear end of the groove on the other side. In this utility model, the use of the guide rod, the bidirectional threaded rod and the connecting blocks makes it easy for users to adjust according to different car sizes. The use of the No. 2 rotating handle, the No. 1 bevel gear, the No. 2 bevel gear and the threaded rod makes it easy for users to adjust the height of the support component for elevator shafts of different depths.
