Problems solved by technology

However, since the counterweight cannot reach behind the grid, it can only roughly detect the expected operating position of the counterweight in its lower end position, which is not conducive to the accurate judgment of the operating state
Since the device described in CN 201842550 has a grid, which is fixed in a steel frame, this device is also expensive and time-consuming to manufacture

Embodiment Construction

[0036] Figure 1a to Figure 1c The elevator installation 100 is shown in different operating states.

[0037] Figure 1a An elevator installation 100 is shown with an elevator car 2 , which is connected to a counterweight 1 by means of ropes by means of deflecting pulleys 3 . The counterweight 1 is in the end position above the stop buffer 4 . The end position is currently substantially between the upper and lower limits of the end position range (not shown here). The elevator car 2 is located in an upper operating position, which is in particular a parking position of the elevator car 2 in the uppermost floor of a proportional building.

[0038] Figure 1b show Figure 1a Elevator equipment in. For clarity, the Figure 1a The reference signs indicated in . The elevator car 2 is located below the end position with an elevator car spacing 2a. However, the counterweight 1 has already reached the stop buffer 4 . Typically, an alarm is triggered and the elevator installa...

Abstract

The invention relates to a device (10) on an elevator installation (100) having a counterweight (1) which can be moved from any operating position into an end position. The device (10) has at least one fixedly arranged, in particular transparent, shielding section (12) arranged at a distance from the counterweight (1) in an end position, on which at least one targeting device (10). The targeting device (10) is arranged in such a way that by targeting the lower edge of the counterweight (1) or a marking on the counterweight (1), the position of the counterweight relative to at least one comparison position can be determined.

Description

technical field [0001] The invention relates to a device for determining the position of an elevator counterweight on an elevator installation with a counterweight and to a method for determining the position of the counterweight. Background technique [0002] Public document CN 201842550 discloses a protection device for a shaft of a counterweight of an elevator device, the protection device is composed of a grid. This enables maintenance work in the shaft pit to be carried out without conflicting with the counterweight. However, since the counterweight cannot reach the back of the grid, it can only roughly detect the expected running position of the counterweight in its lower end position, which is unfavorable for accurate judgment of the running state. Since the device described in CN 201842550 has a grid, which is fixed in a steel frame, this device is also expensive and time-consuming to manufacture. However, a correctly adjusted operating position of the counterweigh...
