Description

Technical Field

[0001] The utility model relates to the field of track detection, in particular to an anti-falling device for a track detection vehicle. Background Art

[0002] Track inspection vehicles, also known as track inspection vehicles, are specialized vehicles used to inspect and evaluate track geometry and irregularities. They are crucial tools for ensuring safe, stable, and comfortable driving and guiding track maintenance and repair. Existing track inspection vehicles can easily cause rollers to bounce when moving along track at high speeds, leading to derailment in severe cases. Utility Model Content

[0003] In view of the above problems, the utility model provides a track inspection vehicle anti-falling device, which can hold the track tightly when the roller bounces up at a high speed and play a deceleration role.

[0004] The technical solution of the utility model is as follows:

[0005] The wheel frame is provided with a plurality of movable wheels, the plurality of movable wheels are provided with a plurality of movable wheels, the plurality of movable wheels are provided with a plurality of movable wheels, and the plurality of movable wheels are provided with a plurality of movable wheels.

[0006] In a further technical solution, two clamping members are symmetrically provided on both sides of each movable wheel.

[0007] In a further technical solution, a friction block is provided at the bottom of the clamping block on the side close to the wheel frame.

[0008] In a further technical solution, a stopper extending to the inner side of the track is provided at the bottom of the wheel frame.

[0009] In a further technical solution, a lifting ring is provided on the top of the limiting block.

[0010] The beneficial effects of the utility model are:

[0011] 1. The vehicle frame moves on the track via the movable wheel. The spring is compressed by the weight of the frame. When the wheel bounces, the spring is de-stressed and extends. The relative position of the wheel frame changes, and the gear meshes with the rack to rotate. The clamping block can be rotated to clamp the track to prevent the vehicle from derailing. The clamping block fits the track and acts as a brake, reducing the speed of the vehicle. The greater the spring extension, the tighter the clamping block fits the track.

[0012] 2. Two clamping parts are provided to clamp the track from both inside and outside, thus improving the stability of the clamping;

[0013] 3. The block can contact the inner side of the track when the frame tilts, which can limit the tilt angle of the frame and facilitate the use of the clamping parts to prevent the track inspection vehicle from derailing;

[0014] 4. The lifting and pulling function on the top of the limit block is convenient for lifting the movable rod and keeping the spring in a compressed state when dismantling the track inspection vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0020] Example:

[0021] like Figure 1-Figure 2As shown, a track 40 inspection vehicle anti-falling device includes a vehicle frame 10, a movable wheel 20 and a clamping member 30. The vehicle frame 10 is mainly used to carry various inspection equipment of the existing track 40 inspection vehicle. The movable wheels 20 are respectively arranged around the vehicle frame 10, including a limit block 21, a movable rod 22, a spring 23, a wheel frame 24 and a roller 25. The vehicle frame 10 is respectively provided with a sliding hole matching the diameter of the movable rod 22. The movable rod 22 is inserted into the sliding hole and can move in the vertical direction relative to the sliding hole. The limit block 21 is provided at the top of the movable rod 22 to prevent the movable rod 22 from detaching from the vehicle frame 10. The wheel frame 24 is provided at the bottom end of the movable rod 22. The spring 23 is sleeved on the outside of the movable rod 22 between the frame 10 and the wheel frame 24, the roller 25 is rotatably connected to the wheel frame 24, and two clamping members 30 are symmetrically provided on both sides of each movable wheel 20; the clamping member 30 includes a mounting block 31, a gear 32, a rack 33 and a clamping block 34, the mounting block 31 is arranged on the outside of the wheel frame 24, the gear 32 is rotatably arranged on the mounting block 31, the clamping block 34 is connected to the gear 32, and the rack 33 is vertically arranged on the bottom of the frame 10 corresponding to the side of the gear 32 close to the wheel frame 24, the gear 32 is meshed with the rack 33, and the movement trajectory of the clamping block 34 does not interfere with the rack 33 and the wheel frame 24.

[0022] The working principle of the above technical solution is as follows:

[0023] The frame 10 moves on the track 40 through the movable wheel 20. The spring 23 is in a compressed state due to the gravity of the frame 10. There is a gap between the clamping block 34 and the track 40 to ensure the normal movement of the roller 25. When the wheel bounces up, the spring 23 is stressed to reduce the extension, and the position of the wheel frame 24 relative to the frame 10 changes. The gear 32 engages with the rack 33 and rotates, so that the clamping block 34 can be rotated to clamp the inner and outer sides of the track 40 to prevent the track 40 inspection vehicle from derailing. The fit between the clamping block 34 and the track 40 can also act as a brake to reduce the speed of the track 40 inspection vehicle. The greater the elongation of the spring 23, the tighter the fit between the clamping block 34 and the track 40.

[0024] In another embodiment, Figure 2 As shown, the bottom of the holding block 34 near the wheel frame 24 is provided with a friction block 35, and the friction block 35 can be made of organic material. Make the friction force of the holding block 34 relative to the track 40 greater, and the braking effect is better.

[0025] In another embodiment, Figure 2 As shown, the bottom of the wheel frame 24 is provided with a stopper 26 extending to the inside of the track 40. The stopper 26 can contact the inside of the track 40 when the frame 10 tilts, which can limit the tilt angle of the frame 10 and facilitate the cooperation with the clamping member 30 to prevent the track 40 detection vehicle from derailing.

[0026] In another embodiment, Figure 2As shown, a lifting ring 27 is provided on the top of the limit block 21. The lifting ring 27 on the top of the limit block 21 is convenient for lifting the movable rod 22 when removing the track 40 inspection vehicle, maintaining the compressed state of the spring 23, and preventing the clamping block 34 from clamping the track 40 due to the extension of the spring 23 when removing the track 40 inspection vehicle.

[0027] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
