Problems solved by technology

And because the protruding sliding bolt engages with the corresponding steel plate installed on the special position on the guide rail, the running path of the car is limited and thus the required temporary safety space is established

Embodiment Construction

[0015] figure 1 The elevator of the invention shown comprises an elevator car 4 which moves vertically along guide rails 3 installed in the shaft 2 . The car 4 includes guide shoes 6 for ensuring that the car 4 moves precisely along the path of the guide rails.

[0016] The technician stands on the top 5 of the car 4 and presses the emergency stop button (not shown) when performing maintenance work. The technician can then use the inspection console 7 to move the car 4 at the inspection speed. Such as figure 2 As shown, the console 7 includes a reversible cover 8 mounted on a hinge 9 . The rod 10 and the support bracket 11 are installed at the position where the car roof 5 abuts against the console cover 8 . The lever 10 is interconnected with the cover 8 and moves simultaneously with the cover 8 . The rod 10 is connected to one end of the central wire of the first flexible cable 12 , while the sheath 14 of the flexible cable 12 is fixed on the support bracket 11 .

Abstract

The invention provides an elevator (1) having a car (4) movable along guide rails (3) mounted in a shaft (2). The elevator (1) comprises an inspection control station (7) mounted on top (5) of the car (4) and accessible via a movable control station cover (8), blocking means (15,20,18) for selectively preventing movement of the car into a safety space (24) within the shaft (2) and actuation means (10,12) for actuating the blocking means (15,20,18). The actuation means (10,12) is configured for concurrent movement with the control station cover (8). Accordingly, a temporary safety space (24) is automatically created within the shaft (2) as the maintenance technician opens the control station cover (8) to move the car (4) using the inspection control station (7).

Description

technical field [0001] The present invention relates to a device and a method for establishing a temporary safety space in an elevator shaft, in particular to a device and a method for mechanically restricting the operation of an elevator car, so as to establish the required space for maintenance personnel performing maintenance operations in the elevator shaft. safe space. Background technique [0002] On the one hand, elevator designers are constantly under pressure to reduce the space occupied by elevator equipment in buildings, but on the other hand, elevator equipment must meet the requirements of industry standards to ensure that the top of the shaft and the pit of the shaft are safe for maintenance workers in the shaft. Provide a corresponding safe space. This safety requirement is usually met by providing a safety space with corresponding safety spaces which are permanently installed above and below the travel path of the elevator car. [0003] Proposals are curren...
