Waterlogging prevention elevator sill

Abstract

The invention relates to a waterlogging prevention preventing elevator sill. A water collecting slot is arranged between the sill and a bracket, the bottom of the water collecting slot is provided with water drain holes, and the lower end of the water collecting slot is connected with a pipe; the pipe is communicated with the water drain holes and is arranged on a well wall, and the lower end of the pipe stretches to be above the a water collecting pit, and the bottom of the water collecting pit is provided with a water pump controlled by a water level switch. The invention has the advantagesthat only a few components are added to guide possible fire water, and the influence of flow water on electrical elements installed on the well wall or on the top of a lift car; the guided water is collected by the water collecting pit, the water pump can discharge the collected water out of the well when collected water reaches a set position, and the normal operation of the elevator is ensure; and the invention has reasonable structure, can be used for manufacturing a new model elevator and can be used for reforming an ole model elevator.

Description

【Technical Field】 [0001] The invention relates to the technical field of elevator design and manufacturing, in particular, to an elevator sill with a water-ingress prevention structure for an elevator elevator. 【Background technique】 [0002] At present, the sill used in the lift elevator is installed in the same place as the floor. There are door shoe slots and dust drop holes on the elevator sill. The structure of the elevator sill is attached. figure 2 , It contains the landing door 1, the sill 2, the dust drop hole 21, the corbel 5 and the duct 4; the sill 2 is installed at the position of the landing door, the corbel 5 is provided under the sill 2, and the dust drop hole 21 is set in The middle of ridge 2. The combination of elevator sill and hoistway is attached figure 1 Shown. The elevator sill provides a guiding function when the elevator landing door is closed, and can prevent the landing door from jamming when foreign objects fall into the boot slot. However, the mai...

Problems solved by technology

However, the main disadvantage of the existing elevator sill is that during fire-fighting operations, the fire-fighting water will flow into the well through the dust holes and other gaps on the sill of the landing door, and flow to the guide rail of the lower landing door along the well wall, causing the lower floors The electrical components on the door guide rail are affected or short-circuited, endangering the electrical components installed on the landing door guide rail and the shaft wall

If the elevator car is located on a lower floor, the water flow will even flow to the top of the car, which will damage the electrical components installed on the top of the car and affect the normal use of the elevator
