Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical assistance, in particular to a rear wheel rotation test auxiliary device of a mobile DR. Background Art
[0002] When testing the rear wheel rotation of the mobile DR, the left and right rear wheels are fixed on the left and right reducers, and they rotate forward and reverse as the reducers rotate forward and reverse.
[0003] The rear wheel rotation test of the mobile DR simulates a rotational motion test of the rear wheel driven by the motor under real usage conditions. If the machine is simply pushed by manpower for testing, it will consume a lot of time and labor costs. On this basis, a test auxiliary device is designed. The rear wheel rotation test can be performed in situ. The device can simulate the real movement of the machine and provide a convenient method for rear wheel testing. Summary of the invention
[0004] The purpose of the present application is to provide a rear wheel rotation test auxiliary device for a mobile DR.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a rear wheel rotation test auxiliary device for a mobile DR, characterized in that it includes a support base, two mounting shafts and two rollers, the mounting shafts are horizontally mounted at the ends of the support base, the rollers are rotatably mounted on the mounting shafts through bearings, a nut is threadedly connected on the mounting shaft, a spring washer and a flat washer are sleeved on the mounting shaft, and the spring washer is arranged between the nut and the flat washer.
[0006] Both sides of the roller are provided with a convex annular limiting portion.
[0007] The middle part of the support base also has an arc-shaped avoidance portion.
[0008] A second flat washer is also sleeved on the installation shaft, and the second flat washer is adjacent to the bearing.
[0009] The nut is a locking nut.
[0010] The bearing is a rolling bearing 6200.
[0011] In summary, the technical effects and advantages of the utility model are:
[0012] 1. The traditional manual test of the rotation of the rear wheels of the mobile DR consumes a lot of time and manpower costs. This device supports the two rear wheels so that the rear wheels can rotate on the original device rollers. It has a simple structure and low cost.
[0013] 2. The auxiliary device uses two rollers, one in front and one in the back, to tightly clamp the rear wheel between the two rollers. When the rear wheel rotates, the two rollers rotate synchronously, and the rear wheel carries the equipment load at the same time, simulating the real movement state of the mobile DR.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] like Figure 1-Figure 3 As shown, the rear wheel rotation test auxiliary device of the mobile DR includes a support base 1, two installation shafts 3 and two rollers 2, specifically: both sides of the roller 2 have a protruding annular limiting portion 2a; the installation shaft 3 is horizontally installed at the end of the support base 1, and the roller 2 is rotatably installed on the installation shaft 3 through a bearing 8, and a nut 4 is threadedly connected on the installation shaft 3, specifically: the nut 4 is a locking nut; a spring washer 5 and a flat washer 6 are sleeved on the installation shaft 3, and the spring washer 5 is arranged between the nut 4 and the flat washer 6; a flat washer 2 7 is also sleeved on the installation shaft 3, and the flat washer 2 7 is adjacent to the bearing 8.
[0021] The support base 1 also has an arc-shaped avoidance portion 1a in the middle.
[0022] The bearing 8 is a rolling bearing 6200 .
[0023] The rear wheel part of the mobile DR is lifted by a hydraulic vehicle, and the assembled device is placed under the two rear wheels of the mobile DR so that the rear wheels are pressed between the two rollers 2. In practice, there is a gap of about 5 mm between the rear wheels and the support base 1.
[0024] The rear wheel is driven to rotate by a reduction motor, so that the rear wheel drives the roller 2 to rotate together. The rear wheel also carries the equipment load, simulating the real movement state of the mobile DR and saving manpower and site costs.
[0025] The device supports the two rear wheels of the mobile DR to simulate the real movement of the machine and performs a rotation test on the rear wheels in situ, thus saving time and labor costs, having a simple structure and low cost.
[0026] In this structure, the fixing method of the roller 2 can be adjusted so that the rear wheel can rotate on the roller 2. All effects of synchronous rotation of the roller 2 and the rear wheel are alternative solutions.
[0027] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
