Problems solved by technology

Since this solution requires several stop elements, switches and other components to realize, it has the disadvantage of complex structure and high cost
[0007] In general, dedicated buffer layouts have the disadvantage of being expensive and complex
A further disadvantage shared by specialized buffers and other support solutions is that they limit the travel of the elevator during maintenance, making the travel of the elevator shorter than the travel distance from the top floor to the bottom floor
Therefore, during the inspection and maintenance process, the elevator can only be driven through a distance shorter than the entire normal travel distance

Embodiment Construction

[0017] in figure 1 In the solution shown, the elevator car 2 is seen in the elevator shaft 1 at a position close to the ground floor 4. Although only the term "elevator car" is used in the following description, it refers to all types of car solutions, such as elevator cars with frames. In order to provide the space required by the "safety block" 9 to meet the elevator standards, the elevator car 2 needs to be completely stopped above the "safety block". in figure 1 In the method, a special safety buffer or support beam used in the prior art is required, or the pit 5 must be made deeper as needed.

[0018] figure 2 A solution based on the present invention is shown, in which the load-bearing floor 3 of the elevator car 2 or a part thereof is arranged to be rotatable around the hinge joint 8 to an upright position or close to an upright position. The hinge joint 8 used as a hinge is located at the front edge of the elevator car, so that when the floor 3 is raised to an upright p...

Abstract

The invention concerns a method and system for forming a safety space in the lower part of an elevator shaft. To provide the required safety space, the floor (3) of the elevator car (2) is removed from its position over the safety space. This is preferably accomplished by turning the floor upward about a hinge (8) in the front edge of the floor so as to bring the floor to a position in front of the door of the elevator car.

Description

Technical field [0001] The invention relates to a method and a device for forming a safe space in the lower part of an elevator shaft. Background technique [0002] A problem often encountered in modernization projects of old buildings is that safety regulations have changed over the years, but the existing lower part of the elevator shaft cannot provide enough safety space to meet the requirements of today's safety regulations. Generally speaking, it is either too expensive or technically impossible to create more space in the lower part of the shaft through modification. For the above reasons, a security solution that requires as little space as possible is usually adopted. [0003] In the existing technology, if possible, the safety space at the lower part of the elevator shaft is realized by forming a safety space with sufficient depth in the pit, so that a "safe square" with a size of at least 500*600*800 mm required by elevator regulations It can be accommodated at least wi...
