A shallow pit elevator

Abstract

The invention discloses a shallow pit elevator. The shallow pit elevator comprises a carrying system which runs on a guide rail, and further comprises a limiting switch device and a stop device; the stop device is disposed above a shallow pit of a liftway and fixed to the guide rail. Enough safety space is guaranteed when an operator performs maintaining operation in the pit through the stop device, toe boards are of a retractable structure, then the height of the pit is reduced, under the condition that the safety is ensured, the depth of the pit is above half smaller than that of a pit of atraditional elevator, the floor space of the pit is reduced, and the pit digging and water-proof cost is reduced.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a shallow pit elevator. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. The part of the shaft below the lowest floor station served by the car becomes the pit, and there should be enough space in the pit to prevent the accidental fall of the car and ensure that the operators entering the pit have enough safe space to avoid being caught by the car. compartment extrusion. For safety reasons, the "Safety Code for Elevator Manufacture and Installation" (GB7588-2003) provides mandatory standard requirements: [0003] When the car is fully pressed on the buffer, there should be enough space in the pit. The size of the space should be able to acco...

Problems solved by technology

[0006] Therefore, the elevator structure in the prior art requires a larger pit space, which increases the cost of floor space, digging, waterproofing, etc.
