Embodiment 1

[0024] like figure 1 , image 3 , Figure 4 As shown, the present invention includes a car mounting base 1, an upper bracket 2 and a lower bracket 3, the car mounting base 1 is fixedly arranged on the center position of the upper bracket 2, and the upper bracket 2 and the lower bracket An X-axis double-wheel load-bearing device 4 that moves freely along the X-axis and a Y-axis double-wheel load-bearing device 5 that moves freely along the Y-axis are arranged between the brackets 3. The upper bracket 2 passes through the X-axis double-wheel load-bearing device 4 and The Y-axis double-wheel bearing device 5 is connected to the lower bracket 3 in a floating manner. A pressure sensor 6 is provided on the X-axis double-wheel load-bearing device 4 and the Y-axis double-wheel load-bearing device 5 , and the pressure sensor 6 is electrically connected to the peripheral console.

[0025] An X motor 7 and a Y motor 8 are arranged on the lower bracket 3, the X-axis double-wheel load-b...

Embodiment 2

[0034] like figure 2 , image 3 , Figure 4 As shown, the difference between this embodiment and the first embodiment lies in that: a rope compensating device 11 is also provided on the lower bracket 3 . The rope compensation device 11 is composed of a single-wheel load-bearing beam 12, a mobile seat 13 slidingly fitted on the single-wheel load-bearing beam 12, a vertical telescopic rod 14 and a horizontal drive motor 15, and the vertical telescopic rod 14 and the horizontal The driving motors 15 are all arranged on the moving base 13 . The connection between the vertical telescopic rod 14 and the horizontal driving motor 15 is realized through a worm gear structure. The upper end of the vertical telescopic rod 14 is provided with a hanging plate 16 . The horizontal drive motor 15 drives the vertical telescopic rod 14 to perform telescopic movement in the vertical direction. The horizontal driving motor 14 is electrically connected with the peripheral console. The horiz...

Abstract

The invention discloses a lift car gravity center tester which is simple in structure, convenient to operate and capable of rapidly capturing a lift car gravity center. The lift car gravity center tester comprises a lift car installation seat (1), an upper support (2) and a lower support (3), the lift car installation seat (1) is fixedly arranged at a central position of the upper support (2), an X shaft double-wheel bearing device (4) doing free motion along an X shaft and a Y shaft double-wheel bearing device (5) doing free motion along a Y shaft are arranged between the upper support (2) and the lower support (3), the upper support (2) is in floating connection with the lower support (3) through the X shaft double-wheel bearing device (4) and the Y shaft double-wheel bearing device (5), a pressure sensor (6) is arranged on both the X shaft double-wheel bearing device (4) and the Y shaft double-wheel bearing device (5), and the pressure sensors (6) are electrically connected with a peripheral control platform. The lift car gravity center tester can be used in the field of elevator lift cars.

Description

technical field [0001] The invention relates to a car gravity center tester. Background technique [0002] The elevator car device is composed of car frame, car floor, car wall, car roof, car door, door machine guide shoe and safety gear. Determining the position of the center of gravity of the car is a relatively complicated subject, because the materials used to make the car are different, different components use different steel materials, and the density of the steel itself is different, so it is difficult to quickly determine the center of gravity of the entire car. [0003] Whether the center of gravity of the elevator car is coplanar with the vertical center line of the top surface of the car guide rail has a great influence on the performance index of the elevator. When the deviation is large, the unilateral line of the guide shoe lining will contact, and the car will give a large bending moment to the different rails, resulting in an increase in energy consumption ...
