Anti-segregation elevator door sill structure and cleaning device

Abstract

The invention discloses an anti-segregation elevator door sill structure and a cleaning device. The door sill structure comprises a sill (1) and a slider (2); the top surface of the sill is provided with a through groove (11), the top of the through groove ( 11) is provided with two limiting plates (12), and the two limiting plates (12) and the two side walls of the through groove (11) are fixed;and the slider (2) includes a slider plate (21), the lower end of the slider plate (21) is inserted into the through groove (11), the two sides of the slider plate (21) are provided with ribs (22) located in the through groove (11), and the two sides of the slider plate (21) are provided with friction plates (23) covering the ribs (22). The anti-segregation elevator door sill structure and the cleaning device have the advantages that the slider cannot be segregated from the sill under the impact force after long-term use, and an accident cannot be caused; and frequent cleaning is not needed, and cleaning is relatively easy.

Description

technical field [0001] The invention belongs to a door sill structure of a passenger elevator, in particular to a door sill structure and a cleaning device for an anti-exit passenger elevator. Background technique [0002] Passenger elevator refers to the elevator used to carry people. The sill structure on the passenger elevator includes a slider and a sill. There is a through groove on the sill. The lower end of the slider is inserted into the through groove and can move along the through groove. The upper end is fixed with the lower end of the landing door, which can prevent the lower end of the landing door from shaking back and forth. [0003] The slider in the door sill structure includes a slider plate, the upper end of the slider plate is fixed to the landing door, and both sides of the lower end of the slider plate are provided with nylon friction plates in the through groove. The function of the nylon friction plates is to reduce slippage. The head-to-head collisi...

[0003] The slider in the door sill structure includes a slider plate, the upper end of the slider plate is fixed to the landing door, and both sides of the lower end of the slider plate are provided with nylon friction plates in the through groove. The function of the nylon friction plates is to reduce slippage. The head-to-head collision between the block plate and the sill produces a large friction noise, but the nylon friction plate will be worn and thinned after long-term use, resulting in the overall thinning of the slider and the increase in the gap between the slider and the through groove

When the landing door is impacted by passengers, the landing door will bend, the upper end of the landing door will not change in height through the connection of the landing door device, and the lower end of the landing door will rise, driving the slider out of the through groove of the sill, resulting in The sill cannot restrict the lower end of the landing door from shaking back and forth. Under the action of the impact force, the lower end of the landing door turns backwards to form a passage, and passengers may fall from t
