Problems solved by technology

The disadvantage is that in the case of 1:1 suspension, the end of the rope moves
This disadvantage does not exist in the 1:2 suspension, but the friction of the guide rail produces deviations

Embodiment Construction

[0017] figure 1 An elevator arrangement according to the invention is shown in which an elevator machine 1 is fastened to a guide rail 2 in an elevator shaft by means of a guide rail fastening device 8 which fastens the elevator machine by means of its upper and lower parts. The dynamic sensor 5 according to the invention is arranged together with the guide rail fastening device 8 . When the load of the car changes, the magnitude and possibly the direction of the force acting on the rope 9 also changes. exist figure 1 In , the center of the elevator machinery is used as the first bearing point, which bears the vertical forces Fy and 2. The attachment point of the dynamic sensor 5 also serves as a load-carrying bracket, receiving the force Fn generated by the torque. The load acting via the rope thus produces a torque on the machine, and this torque, ie the unbalanced moment, is detected by the dynamic sensor 5 .

Abstract

Elevator arrangement for setting the starting torque of the motor of an elevator machinery, the elevator machinery (1) being mounted on a guide rail (2) in an elevator shaft. The elevator arrangement comprises at least one power sensor (3, 4, 5, 6) for determining the imbalance moment that the car load produces in the elevator machinery.

Description

technical field [0001] The invention relates to an elevator installation for setting the starting torque of an elevator machine. Background technique [0002] In an elevator installation consisting of an elevator car, a counterweight and an elevator installation driving them, the unbalanced moment varies greatly. Generally, each time when the car stops on the platform, the change of its load causes the unbalanced torque of the elevator device to change, so the starting torque of the motor of the elevator device is set according to the constant load. [0003] Currently, the required starting torque is determined using, for example, a load weighing device in the car. In this case, a power sensor is placed between the car and the car frame. Such a structure is difficult to apply to a new elevator of a so-called frameless car structure having an integrated car and car frame. In addition, long transmission lines are required between the car and the control system, and they are...
