[0055] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with the implementation modes.

[0056] Generally speaking, when a train needs to be inspected, it will be parked in the inspection pit track or spare track in the train inspection depot. When the train is parked in one track, the train inspection equipment can run in another track and complete the train inspection by extending the image acquisition device to capture images of the bottom of the train. This requires that the wheels in the train inspection equipment must not only be able to run on normal land surfaces, but also need to adapt to the inspection track where the train to be inspected is located.

[0057] The present application provides a telescopic wheel for train inspection equipment, which can be driven on normal land surfaces and can also be driven on the inspection track where the train to be inspected is located without manual wheel replacement. Figure 1-5 As shown, it includes: a tire 1, a telescopic steel wheel 2, a rim 3, a telescopic control part 4 and a rotation control part 5.

[0058] Among them, the wheel rim 3 can be understood to refer to the inner part of the wheel profile of the railway train, which is used to prevent the train from derailing. The tire 1 is arranged in the outer layer of the wheel rim 3; the telescopic steel wheel 2 is telescopically arranged in the wheel rim 3, so that the telescopic steel wheel 2 is nested in the tire 1; and the central rotation axes of the tire 1 and the telescopic steel wheel 2 are aligned. The telescopic control unit 4 is connected to the telescopic steel wheel 2 to control the telescopic steel wheel 2 to extend or retract into the wheel rim 3; the rotation control unit 5 is connected to the telescopic steel wheel 2 to control the telescopic steel wheel 2 to rotate synchronously with the tire in the retracted state, and the train inspection equipment uses the tire to move on the ground; or the telescopic steel wheel is controlled to rotate alone in the extended state, and the train inspection equipment uses the telescopic steel wheel to move in the detection track.

[0059] In the present application, the tire 1, the rim 3 and the telescopic steel wheel 2 can be understood as a whole, which are the tire 1, the rim 3 and the telescopic steel wheel 2 from the outside to the inside. However, the telescopic steel wheel 2 can extend or retract the rim 3 under the control of the telescopic control unit 4, that is, extend or retract the tire 1, which makes the present application have "two usable wheels" in one structure.

[0060] Recombination Figure 6 As shown, when the telescopic steel wheel 2 extends out of the wheel rim 3, the corresponding Figure 3 In states 2 and 3, the telescopic steel wheel 2 can be set up in the detection track, so that the train inspection equipment equipped with the present application can travel in the detection track; and when the telescopic steel wheel 2 extends out of the wheel rim 3, the corresponding Figure 3 In state 1, the telescopic steel wheel 2 can be detached from the detection track. At this time, the overall structure of the present application is on the ground, so that the train inspection equipment equipped with the present application can travel on the ground. It can be understood that the detection track is generally at a certain height from the ground, so when the telescopic steel wheel 2 in the present application is set on the detection track, the tire 1 can be detached from the ground, so that the entire application will not travel on the ground. In addition, since the central axis of rotation of the tire 1 and the telescopic steel wheel 2 is consistent, when the telescopic steel wheel 2 retracts the tire 1, the rotation control unit 4 controls the telescopic steel wheel 2, which is equivalent to controlling the tire 1, and the rotation speeds of the two wheels are consistent.

[0061] Preferably, the telescopic control part 4 comprises: a bottom plate 41, a slide plate 42 and a slider 43. The slide plate 42 is fixed on the bottom plate 41, and the slider 43 is slidably arranged in the slide plate 42. When the slider 43 slides, the telescopic steel wheel 2 can be driven to extend or retract the wheel rim 3.

[0062] The rotation control unit 5 includes a rotating shaft 51 and a rotating shaft bearing seat 52. The rotating shaft 51 is inserted into the rotating shaft bearing seat 52 and connected to the axis of the telescopic steel wheel 2. The rotating shaft 51 rotates to drive the telescopic steel wheel 2 to rotate. The rotating shaft bearing seat 52 is fixed to the slider 43, so that when the slider 43 slides, the rotating shaft 51 and the rotating shaft bearing seat 52 are driven to move, thereby driving the telescopic steel wheel 2 to extend or retract.

[0063] That is, the rotating shaft 51 can drive the telescopic steel wheel 2 to rotate independently in the extended state or drive the tire 1 to rotate as a whole in the retracted state. The extension and retraction states of the telescopic steel wheel 2 are controlled by the slider 43.

[0064] Preferably, the rotation control unit 5 further includes: a motor 53 and a motor bracket 54. One end of the rotating shaft 51 is connected to the telescopic steel wheel 2, and the other end is connected to the motor 53, and the motor 53 is fixed to the slider 43 through the motor bracket 54. That is to say, the motor 53 and the motor bracket 54 will also move with the movement of the slider 43.

[0065] Preferably, the rotation control unit 5 further includes a coupling 55. The motor 53 is connected to the rotating shaft 51 via the coupling 55 to control the rotation speed of the rotating shaft 51.

[0066] Preferably, the wheel further includes a spoke 6 ; and the spoke 6 includes: a spoke mounting hole 61 , a bearing mounting groove 62 ; the rim 3 further includes: a rim spoke mounting hole 31 ; and the rotation control unit 5 further includes: a center bearing 56 .

The center bearing 56 is fixed on the spokes 6 through the bearing mounting groove 62, and the center bearing 56 is provided with a rotating shaft 51, so that when the rotating shaft 51 rotates, the spokes 6 and the rim 3 are driven to rotate.

[0068] It can be understood that in the present application, the tire 1, the telescopic steel wheel 2, the rim 3 and the spoke 6 can be understood as a whole, and when the telescopic steel wheel 2 rotates, all mechanisms in the whole rotate synchronously.

[0069] Preferably, the spoke 6 further includes: a spoke bearing mounting platform 63 ; the rotation control unit 5 further includes: a bearing baffle 57 and a wheel bearing seat 58 .

[0070] The bearing baffle 57 is connected to the wheel bearing seat 58, and the spoke bearing mounting platform 63 is arranged on the wheel bearing seat 58, and one end is fixed to the bearing baffle 57, so that the wheel bearing seat 58 is fixed to the spoke 6. In addition, the wheel bearing seat 58 is also movably penetrated with a rotating shaft 51, and the wheel bearing seat 58 is connected to the bottom plate 41, so that one end of the bottom plate 41 is connected to the spoke 6 through the wheel bearing seat 58.

[0071] It is understandable that the rotating shaft 51 is movable in the wheel bearing seat 58. When the slider 43 slides, it can drive the rotating shaft 51 and the rotating shaft bearing seat 52 to move, but the bottom plate 41 and the wheel bearing seat 58 do not move with the sliding of the slider 43.

[0072] Preferably, the telescopic steel wheel 2 comprises: a steel wheel boss 21; and the wheel rim 3 further comprises: a wheel rim groove 32.

One end of the telescopic spring 34 is fixed in the wheel rim spring groove 33, and the other end is fixed inside the steel wheel spring groove 22. When the telescopic steel wheel 2 extends out of the wheel rim 3, the telescopic spring 34 is compressed, and when the telescopic steel wheel 2 retracts into the wheel rim 3, the telescopic spring 34 releases the compression.

[0074] Preferably, the telescopic steel wheel 2 includes: a steel wheel inner ring 23; the wheel also includes: a nylon inner core 7. The rotating shaft 51 is fixed to the nylon inner core 7, and the rotation of the rotating shaft 51 drives the nylon inner core 7 to rotate, and the nylon inner core 7 is also fixed to the telescopic steel wheel 2 through the steel wheel inner ring 23, so that the rotating shaft 51 drives the telescopic steel wheel 2 to rotate.

[0075] Preferably, the wheel rim 3 further comprises a wheel rim tire fixing hole 35, so that the tire 1 is mounted on the wheel rim 3 through the wheel rim tire fixing hole 35. When the wheel rim 3 rotates, the tire 1 also rotates synchronously.
