[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is a monorail train running wheel bearing detection device, comprising a moving trolley, a prying assembly, a detection assembly, and a hydraulic station; the hydraulic station is arranged on one side of the handle of the moving trolley, the prying assembly is arranged in front of the hydraulic station, and the detection assembly is respectively arranged under the prying assembly and on the support plate of the moving trolley;

[0005] The prying assembly comprises a fixed pry arm, a movable pry arm and a pry arm oil cylinder; the movable pry arm is connected to the pry arm oil cylinder, is arranged on the fixed pry arm, is shaped like a scissors, and is arranged on one side of the mobile trolley. The ends of the fixed pry arm and the movable pry arm are both provided with pry hooks;

[0006] The detection component includes a rotating wheel device, a supporting cylinder and a displacement sensor; the rotating wheel device is arranged under the prying component and on the structure in front of the hydraulic station, and is composed of a motor connected to a reducer and a rotating wheel; the supporting cylinder and the displacement sensor are arranged on the mobile trolley pallet and under the inspected walking wheel.

[0007] The beneficial effects of the utility model are that it has a simple and practical structure, can be directly pushed to the side of the wheel to be tested, and the wheel can be directly pried instead of removed to the device to quickly and reliably test whether the bearing is damaged, thus saving time and effort and filling the market gap.

[0019] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] like Figure 1 to Figure 2 As shown, the utility model discloses a monorail train running wheel bearing detection device 100, comprising a moving trolley 1, a prying assembly 2, a detection assembly 3, and a hydraulic station 4; the hydraulic station is arranged on one side of a handle 11 of the moving trolley, the prying assembly is arranged in front of the hydraulic station, and the detection assembly is arranged under the prying assembly and on a support plate 12 of the moving trolley respectively;

[0021] The prying assembly 2 comprises a fixed pry arm 21, a movable pry arm 22 and a pry arm oil cylinder 23; the movable pry arm is connected to the pry arm oil cylinder, is arranged on the fixed pry arm, is shaped like a scissors, and is arranged on one side of the mobile trolley. The ends of the fixed pry arm and the movable pry arm are both provided with pry hooks 24;

[0022] The three parts of the detection group include a rotating wheel device 31, a supporting cylinder 32 and a displacement sensor 33; the rotating wheel device is arranged under the prying assembly and on the structure in front of the hydraulic station, and is composed of a motor 311 connected to a reducer 312 and a rotating wheel 313; the supporting cylinder and the displacement sensor are arranged on the mobile trolley pallet and under the inspected walking wheel.

[0023] The hydraulic station is arranged on the framework.

[0024] The mobile trolley is a universal trolley and can be purchased directly.

[0025] The working process of this device is as follows:

[0026] Manually push the mobile trolley into the wheel station so that the trolley fits the wheel beam completely;

[0027] Start the pry arm oil cylinder, then the fixed pry arm pry hook presses tightly against the wheel beam, the movable pry arm pry hook is inserted between the tire and the wheel beam, and the pry arm pry hook is used to pry the tire away from the wheel beam and into the device by taking advantage of the flexibility of the inflated tire;

[0028] The travel wheel is driven to rotate through the rotating wheel device, and the supporting cylinder is activated every 90 degrees. The displacement sensor is used to detect whether there is any displacement change in the corresponding position. The change is used to determine whether the bearing is damaged, so that corresponding measures can be taken to ensure the safety of train operation.

[0029] The above is only one of the embodiments of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
