Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator car top with adjustable elevator glue. Background Art

[0002] Elevator clamps are installed on the elevator roof of the elevator car. They are mainly used to fix and position the car and columns. They can adjust the position of the car.

[0003] For example, the Chinese patent with publication number CN211034839U discloses a sliding groove type fixing device for the elevator car top plate, which is installed on the C-shaped grooves on both sides of the elevator car top plate; it includes a sliding pipe, a bolt assembly and a car top clamp for fixing and buffering; the sliding pipe is adjustably connected to the C-shaped groove through the bolt assembly to adjust the position of the connection between the elevator car top plate and the column; the car top clamp is adjustably connected to the sliding pipe to adjust the distance between the car top clamp and the column. First, put the bolt assembly into the C-shaped groove, and screw the bolt clamp into the C-shaped groove by rotating it so that the bolt clamp is perpendicular to the C-shaped groove to ensure that the bolt assembly will not fall out of the C-shaped groove when moving up and down. Then put the sliding pipe into the bolt assembly. At this time, the position of the sliding pipe can be adjusted according to the position of the on-site column and the splicing position avoiding the car top card plate. When the bolt is halfway into the sliding pipe and the position is determined, a nut needs to be installed. The sliding pipe, the bolt card plate and the C-shaped groove can be firmly fixed by tightening the nut, and finally the nut is added to the sliding pipe. After the sliding pipe is clamped, the car top card plate is installed, and the distance between the car top card plate and the column is adjusted through the waist hole on the car top card plate.

[0004] In the above patent, two car top clamps are arranged on the same sliding pipe at the same time, and the two car top clamps constitute a glue-locking device cooperating with the column. Although this method can realize the position adjustment of the car top clamp by adjusting the position of the sliding tube, but because the two car top clamps of the glue-locking device are installed on the same sliding pipe, the relative distance between the two car top clamps of the glue-locking device is difficult to adjust. Even if it can be adjusted, it is limited by the connecting bolts between the car top clamp and the sliding pipe, resulting in the adjustable distance between the two car top clamps being limited, and it is difficult to meet more adjustment requirements.
