Abstract

The invention discloses measuring equipment for a balance coefficient of an elevator. The equipment includes a rope clamp weighing device and a fixing seat, the rope clamp weighing device is composedof a steel wire rope clamp and a pressure sensor, the pressure sensor is fixedly installed on the upper side of the steel wire rope clamp, and the fixing seat is arranged above the pressure sensor. Ingeneral, the equipment has the advantages of having a simple structure, being convenient and quick to install and use, capable of effectively improving the measurement efficiency, reducing the influence of artificial factors and improving the measurement accuracy, and installed on the car side or the counterweight side according to the environment, and having extremely high use value.

Description

technical field [0001] The invention belongs to the technical field of elevator auxiliary operation equipment, and relates to a measuring device, in particular to an elevator balance coefficient measuring device. Background technique [0002] The elevator balance factor is an important performance index of the traction drive elevator, which needs to be measured on site. Reasonably setting the elevator balance coefficient can not only ensure that the elevator brake brakes within its braking range, but also save a lot of electric energy resources. The car and the counterweight of the traction elevator are suspended on both sides of the traction sheave respectively through steel wire ropes. Section G2.4 in GB7588-2003 gives the definition of the balance coefficient (q), that is, the rated load and the quality of the car are determined by the pair Weight or counterweight The amount to balance. Therefore, its calculation formula: [0003] q=(W-P) / Q [0004] Among them: q—bala...
