Description

Technical Field

[0001] This utility model relates to the field of nylon wheel testing technology, specifically to a stability testing device for elevator nylon wheels. Background Technology

[0002] Nylon is a general term for thermoplastic resins containing repeating amide groups —[NHCO]— in their molecular backbone. Due to its many properties, nylon is widely used in automobiles, electrical equipment, mechanical parts, transportation equipment, textiles, papermaking machinery, and other fields. The rollers used in the elevator industry are usually made of nylon. After the nylon rollers used in elevators are manufactured, they need to be tested to ensure the safety of subsequent operation. Therefore, stability testing devices are required.

[0003] Existing stability testing devices fix nylon wheels on a testing frame, then put a belt on the nylon wheels, with the other end of the belt on another set of nylon wheels. The hydraulic cylinder pushes the nylon wheel to be tested to move, and the force test is performed on the nylon wheel when it is stationary. However, the position where the belt contacts the nylon wheel is prone to deformation after the belt is stretched, which can easily cause deviations in the test data.

[0004] The aforementioned stability testing device is prone to errors in the measurement data obtained by the operator because the belt in contact with the nylon wheel is easily deformed during the movement of the nylon wheel, thus reducing the effectiveness of the device. Utility Model Content

[0005] This invention proposes a stability testing device for elevator nylon wheels to solve the problem in the prior art where the belt in contact with the nylon wheel easily deforms during movement, leading to deviations in the operator's test data.

[0006] The technical solution of this utility model is as follows: A stability testing device for elevator nylon wheels includes a nylon wheel body, and also includes a connecting ring, ball bearings, a connecting plate, a first adjusting frame, a first adjusting pin, a support wheel, a second adjusting frame, a second adjusting pin, a first fixing plate, and an auxiliary mechanism;

[0007] The connecting ring is disposed on the outer surface of the nylon wheel body, and a ball bearing is rotatably connected inside the connecting ring. A connecting plate is mounted on the lower surface of the connecting ring. The first adjusting frame is slidably connected to the outer surface of the connecting plate. A first adjusting pin is threaded through the outer surface of the first adjusting frame, and one end of the first adjusting pin is threaded through the inner surface of the first adjusting frame and abuts against the connecting plate. A support wheel is mounted on the inner surface of the first adjusting frame. The second adjusting frame is slidably connected to the outer surface of the connecting plate. A second adjusting pin is threaded through the inner surface of the second adjusting frame, and one end of the second adjusting pin is threaded through the inner surface of the second adjusting frame and abuts against the connecting plate. The first fixing plate is mounted on the outer surface of the second adjusting frame, and an auxiliary mechanism is provided on the outer surface of the connecting plate.

[0008] As a preferred embodiment of the stability testing device for elevator nylon wheels described in this utility model, the auxiliary mechanism includes a support rod, a third adjusting frame, a third adjusting pin, a second fixing plate, and a counterweight bar to facilitate operator adjustment. The support rod is mounted on the lower surface of the first fixing plate. The third adjusting frame is slidably connected to the outer side of the connecting plate. A third adjusting pin is threaded through the inner surface of the third adjusting frame, and one end of the third adjusting pin, threaded through the third adjusting frame, abuts against the connecting plate. The second fixing plate is mounted on the outer side of the third adjusting frame. The bottom end of the support rod is mounted on the upper surface of the second fixing plate, and a counterweight bar is provided on the outer surface of the support rod.

[0009] As a preferred embodiment of the stability testing device for elevator nylon wheels described in this utility model, in order to facilitate the operator to rotate the nylon wheel body, a drive shaft runs through the interior of the nylon wheel body, a first support plate is rotatably connected to the outer surface of the drive shaft, and a second support plate is installed on the lower surface of the first support plate.

[0010] As a preferred embodiment of the stability testing device for elevator nylon wheels described in this utility model, in order to facilitate operators to test the nylon wheel body, the first support plate has an installation groove inside, the outer end of the transmission shaft is equipped with an operating disc, and a plug-in post passes through the inside of the nylon wheel body.

[0011] As a preferred embodiment of the stability testing device for elevator nylon wheels described in this utility model, in order to prevent the nylon wheel body from slipping off the surface of the drive shaft during the testing process, a connecting tube is sleeved on the outer surface of the drive shaft, and a connecting pin is threaded through the outer surface of the connecting tube. One end of the connecting pin, which is threaded through the connecting tube, abuts against the drive shaft.

[0012] As a preferred embodiment of the stability testing device for elevator nylon wheels described in this utility model, in order to better fix the nylon wheel body, a blocking plate is installed on the outer surface of the connecting pipe, a fixing pin is threaded through the outer side of the blocking plate, and one end of the fixing pin is threaded through the blocking plate and threaded into the plug-in post.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, the ball bearings and support wheel contact the nylon wheel body, allowing the ball bearings and support wheel to rotate simultaneously with the nylon wheel body. Compared to the prior art of directly detecting via a belt, this device can increase the weight of the nylon wheel body without affecting the detection data, thus preventing deformation of the connecting ring after the operator finishes the detection.

[0015] In this invention, by stacking multiple sets of counterweights on the upper surface of the second fixed plate, the support rod enters the interior of the counterweights. Compared with the prior art which directly pushes the nylon wheel body to move, this device can slowly pressurize the nylon wheel body, thus improving the device's performance.
