Elevator lift car load weighing device

Abstract

The invention discloses an elevator lift car load weighing device, which comprises an installing plate, a sensor probe and sensor square magnetic steel, wherein the sensor probe is arranged on the installing plate, the sensor square magnetic steel is arranged on a rope end plate, the sensor probe is over against the sensor square magnetic steel, in addition, a sensing distance is left between the sensor probe and the sensor square magnetic steel, an installing hole is arranged in the installing plate, a screw rod is penetrated in the installing plate, and the installing plate is tightly clamped between a pair of screw nuts. The lift car load measurement is based on the displacement generated through the lift car load stress and is irrelevant with whether the lift car load is balanced or not, so the measurement is accurate. During the lift car load measurement, the sensor probe and the square magnetic steel are arranged on a rope end assembly and the rope end plate, so the installation and the debugging of elevators with equipment rooms can be directly carried out in the equipment rooms, for elevators without equipment rooms, installation personnel can directly install the sensor probe and the square magnetic steel during the installation of a lift car or a counterpoise rope end frame, the lift car is stopped in a proper position during the debugging, the operation can be carried out on the top of the lift car, and the operation is very convenient.

Description

[0001] technical field [0002] The invention relates to an elevator car load weighing device. Background technique [0003] In the prior art, the sensor probes and square magnetic steel used for car load weighing are installed under the car floor, and must be adjusted at the center of the car. When debugging, the car needs to be parked at a proper position on the bottom floor, and then the debugging After the personnel enter the bottom pit, they debug the sensors on the car floor, such as adjusting the distance between the probe and the square magnetic steel, which is very inconvenient to operate. The existing sensor probe and square magnetic steel are installed under the car bottom, and the car load is detected by measuring the deformation of the shock-absorbing rubber under the car bottom. In this way, if the car load is unbalanced, such as the position of the passenger station in the car deviates from the car The center of the car makes it difficult to accurately determ...

Problems solved by technology

[0003]In the prior art, the sensor probe and square magnetic steel used for car load weighing are installed under the bottom of the car, and must be adjusted at the center of the car. At this time, the car needs to be parked at a proper position on the ground floor, and then the debugging personnel enter the pit to debug the sensors on the car bottom, such as adjusting the distance between the probe and the square magnetic steel, which is very inconvenient

The existing sensor probe and square magnetic steel are installed under the car bottom, and the car load is detected by measuring the deformation of the shock-absorbing rubber under the car bottom. In this way, if the car load is unbalanced, such as the position of the passenger station in the car deviates from the car The center of the car makes it difficult to accurately determine the deformation of the rubber, resulting in inaccurate car load measurement
