Description

Technical Field

[0001] The utility model relates to the technical field of rotational torque testing, in particular to an elevator pan wheel rotational torque testing device. Background Art

[0002] The pan wheel is a component of an elevator's traction machine. In the event of an elevator malfunction, the pan wheel must be manually positioned on the elevator's central shaft and then rotated to control the elevator's movement. Pan wheels commonly used on the market are made of iron and consist of a smooth disc with a central hole and a rotating sleeve bolted to the disc. Due to the varying shapes of the central shafts of different elevators, the current approach involves equipping elevators with rotating sleeves of varying shapes to meet specific requirements.

[0003] The existing elevator disc wheel needs to be tested for its rotational torque before it is put into use. The existing testing method is usually to manually use a motor to drive the elevator disc wheel to rotate and use a torque sensor to perform the test. However, this testing method does not have weight data adjustment, resulting in inaccurate data. For this reason, we proposed an elevator disc wheel rotational torque testing device. Utility Model Content

[0010] Preferably, the output end of the second motor is fixedly connected to one end of a screw rod, and the screw rod is matched with the second slider.

[0011] The utility model provides an elevator pan wheel rotation torque test device, which has the following beneficial effects:

[0012] The elevator disc wheel rotation torque testing device drives the first shaft to rotate by utilizing the first motor to drive the first coupling to rotate, activates the torque sensor by means of the rotation of the first shaft, and drives the second coupling to rotate at the same time, drives the second shaft at one end to rotate by means of the rotation of the second coupling, and drives the elevator disc wheel to rotate by means of the second shaft. Thus, when the elevator disc wheel rotates, the torque test can be completed by using the torque sensor, and the torque data can be obtained.

The first motor 2 drives the first coupling 3 to rotate, and the first rotating shaft 4 is driven to rotate by the first motor 2. One side of the second mounting plate 21 is rotatably connected There is a third rotating shaft 26, and a third coupling 27 is provided on the outside of the third rotating shaft 26. One end of the elevator disk wheel 8 is fixedly connected to the second rotating shaft 7. The second coupling 6 is provided on the outside of the second rotating shaft 7.

The rotation of the second coupling 6 can drive the second rotating shaft 7 at one end to rotate. The other end of the elevator disk wheel 8 is connected to the third coupling 27. The elevator disk wheel 8 can be driven to rotate by the second rotating shaft 7. Therefore, when the elevator disk wheel 8 rotates, the torque sensor 5 can be used to complete the torque test work and obtain the torque data.

[0020] A cable 9 is provided on the outside of the elevator disk wheel 8, and a first weight-increasing box 15 is fixedly installed on one end of the cable 9. By winding the cable 9 around the outside of the elevator disk wheel 8 and then placing a weight-increasing block inside the first weight-increasing box 15, a fixing plate 14 is fixedly installed on the bottom of the base plate 1, and a first slide groove 13 is opened on one side of the fixing plate 14. A first slider 12 is fixedly installed on one side of the first slide groove 13. The first slider 12 is fixedly connected to the first weight-increasing box 15.
