Detailed Description
The door hanging plate is one of the parts for realizing the automatic opening and closing functions of the automatic door of the elevator, and is used for connecting the elevator door and an elevator driving device. Specifically, one end of the door hanging plate is connected with a transmission structure with driving force, and the other end of the door hanging plate is connected with the elevator door. The door hanging plate is generally provided with a pulley, and the pulley enables the door hanging plate to slide back and forth on the guide rail, so that the driving device drives the elevator door to be opened or closed. The invention will be further explained with reference to the following description and examples in conjunction with the accompanying drawings:
referring to fig. 1 to 5, an automatic door pulley block for an elevator comprises a door hanging plate 41, a pulley 31 and a limiting wheel 33, wherein the pulley 31 and the limiting wheel 33 are connected with the door hanging plate 41, a folded edge extending along the back direction is arranged at the bottom of the door hanging plate 41, symmetrical convex parts 42 are arranged at two ends of the top of the door hanging plate 41, through holes 43 are arranged on the convex parts 42, the pulley 31 is rotatably bolted to the door hanging plate 41 through the through holes 43, and a flat groove 52 is arranged on the outer ring of the pulley 31;
the top end of the car of a commercial or domestic elevator is generally provided with a rectangular guide rail on which the elevator door slides for opening and closing, and the pulley 31 slides. The two ends of the top of the door hanging plate 41 are provided with convex parts 42, which act to increase the distance between the pulleys 31, so that the sliding is more stable when the pulleys 31 drive the door hanging plate 41 and the elevator door to slide. The outer ring of the pulley 31 is formed as a flat groove 52, and is slidably engaged with the rectangular guide rail, so that the sliding is more stable.
The door hanging plate 41 is used as a connecting piece for connecting the elevator door, and the thickness of the door hanging plate is 2.5-4.0 mm.
The door hanging plate 41 is provided with symmetrical oval through holes 44 near the bottom end, the length extending direction of the oval through holes 44 is inclined to the horizontal line direction, and the limiting wheel 33 is rotatably connected to the door hanging plate 41 through the oval through holes 44 through bolts.
One side of the limiting wheel 33, which is far away from the door hanging plate 41, is provided with a limiting plate 34, the limiting plate 34 is arranged in a fan shape, the limiting plate 34 is provided with a bent part 51, the bent part 51 is arranged in a right angle, and the limiting plate 34 is rotatably connected to the limiting wheel 33.
The limiting plate 34 on one side of the limiting wheel 33 is mainly used for limiting the further movement of the door hanging plate 41. The bending part 51 of the limiting plate 34 is arranged at a right angle, when the elevator door works, the limiting plate 34 is arranged upwards, the bending part 51 keeps a certain distance from the right-angle edge of the square guide rail, and the door hanging plate which is abnormally deviated is limited. Because the front of square guide rail is equipped with door link plate 41, and the back is equipped with limiting plate 34, the top surface is equipped with the pulley 31 of butt, and the bottom surface is equipped with the spacing wheel 33 of butt, so the utility model discloses be parcel type structure, when the lift-cabin door receives the exogenic action, can avoid door link plate 41 to break away from the guide rail, cause the lift-cabin door to open normally or close.
The back of the door hanging plate 41 is provided with symmetrical positioning portions, each positioning portion comprises a fixing column 54 and a positioning bolt 55, the fixing column 54 is connected to the door hanging plate 41, the length extending direction of the fixing column 54 is consistent with that of the oval through hole 44, the fixing column 54 is hollow and provided with internal threads, the positioning bolt 55 is rotatably connected with the fixing column 54, and one end of the positioning bolt 55 abuts against a bolt connected with the limiting wheel 33.
Preferably, positioning nuts 56 are disposed on two sides of the fixing post 54, and the positioning nuts 56 are sleeved on the positioning bolts 55 and rotate oppositely along the fixing post 54 to abut against the fixing post 54.
The positioning part acts on the limiting wheel 33 for limiting, and looseness and deviation of the limiting wheel are avoided. Because the elevator door runs for a long time, the bolt connected with the limiting wheel and the limiting wheel 33 can be loosened by the vibration generated in the running process, the positioning bolt 55 can be adjusted, and one end of the positioning bolt 55 is abutted against the bolt connected with the limiting wheel to prevent the limiting wheel 33 from being loosened; positioning nuts 56 abutting against the fixing posts 54 are provided on both sides of the fixing posts 54, and act on the stable positioning bolts 55 to prevent the positioning bolts 55 from being removed from the fixing posts 54 due to long-term vibration.
