Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a height-adjustable cushion block between an elevator shaft frame column and a wall. Background Art

[0002] The installation of various components of the elevator is basically connected by bolts. The various components of the elevator are assembled into a component. Each component has corresponding functions. Some components or parts need to be adjusted according to the actual situation on site. The components cannot be fixed when leaving the factory and need to be adjusted within a certain range. For example: when the aluminum alloy well frame of the elevator is actually installed on site, the distance from each connection point to the civil engineering fixed point will deviate. At this time, it needs to be adjusted according to the actual situation.

[0003] At present, most of the derricks and civil engineering on the market are fixed by drilling holes in the columns, and then using an impact drill to drill holes in the wall through the holes in the derrick columns, and then hammering in long expansion bolts to fix them, such as Figure 1 As shown, at this time, the distance between the side of the derrick column and the wall is adjusted by inserting a U-shaped opening gasket. This method is troublesome to operate and requires multiple insertions of gaskets to accurately adjust. If the bolts are not tightened, there is a risk that the U-shaped opening gasket will fall off. Some screws are locked with nuts on both sides, such as Figure 2 As shown, in this case, the torsional resistance of the screw is very long and its ability to withstand lateral swing is poor.
