Description

Technical Field

[0001] The utility model relates to the technical field of tunnel engineering machinery, in particular to a tunnel inspection vehicle which can adapt to different tracks. Background Art

[0002] Tunnel inspection vehicles are very important technical equipment in the maintenance of tunnels such as high-speed railways and railways. They are used to detect key parameters in tunnels, ensure the safety of tunnel operations and improve the comfort of tunnel use. In the early stages of tunnel construction, tunnel inspection vehicles can be used to conduct detailed inspections of the integrity, geometric dimensions, internal damage, etc. of the tunnel structure to ensure that the construction quality meets the design requirements. After the tunnel is built, tunnel inspection vehicles are also needed to regularly inspect the operating tunnels to assess the stability and health of the tunnel structure, and to promptly detect and deal with potential damage or safety hazards. When upgrading, expanding or reinforcing tunnels, tunnel inspection vehicles can be used to assess the status of existing structures and provide data support for design plans. Tunnel inspection vehicles can also be used to conduct detailed investigations of the accident site after an accident in the tunnel, analyze the cause of the accident, and provide technical support for accident handling.

[0003] However, although the existing tunnel inspection vehicles can collect vehicle and tunnel lining surface information in real time under normal driving conditions, the spacing of the wheels at the bottom of the vehicles is often not easy to adjust, so it is difficult to adapt to tracks of different sizes or terrain requirements. If they encounter tracks with different track gauges, structural parameters or special terrain, they may not be able to flexibly change the wheelbase, resulting in failure to drive normally. At the same time, if the tunnel inspection vehicle cannot match various tracks and driving conditions, it will be difficult to achieve effective detection in multiple scenarios, which will affect the efficiency of the detection work. If different tunnel inspection vehicles are required for different tracks or scenarios, then for the operation and management party, it is necessary to purchase and maintain multiple models of inspection vehicles, which will increase equipment costs and subsequent maintenance expenses.

[0004] Therefore, it is necessary to design a tunnel inspection vehicle that can flexibly adjust the wheelbase and adapt to different tracks. Utility Model Content

[0005] The utility model provides a tunnel inspection vehicle which can adapt to different tracks, aiming to solve one or more of the above problems and other potential problems.

[0006] The utility model provides a tunnel inspection vehicle that can adapt to different tracks, characterized in that it comprises an inspection vehicle body, a first movable component arranged under the inspection vehicle body and used for driving the inspection vehicle body to move and with a fixed wheelbase, a second movable component arranged under the inspection vehicle body and used for driving the inspection vehicle body to move and capable of adjusting the wheelbase according to the track gauges of different tracks, wherein the second movable component comprises a roller assembly capable of adjusting the wheelbase according to the track gauges of different tracks and an adjusting portion for adjusting the wheelbase of the roller assembly.

[0007] The utility model is provided with a second movable component which can adjust the wheelbase according to the track gauge of different tracks, and the second movable component is independent of the first movable component. When the wheelbase of the second movable component is adjusted, the moving state of the first movable component is not affected, and rapid switching can be performed during driving.

[0008] In the embodiment, the first movable component is composed of a roller and a roller with a fixed wheelbase. The wheelbase of the first movable component is suitable for conventional tracks. When driving on conventional tracks, the first movable component is used to drive the tunnel inspection vehicle to move. At this time, the first movable component conflicts with the track, and the second movable component is suspended and does not work. When it is necessary to switch to an unconventional track where the track gauge does not match the wheelbase of the first movable component, the wheelbase of the roller assembly is adjusted by the adjustment unit to make it match the track gauge of the track to be driven. The adjustment process of the roller assembly is independent of the movement of the first movable component and will not affect the moving state of the first movable component. Therefore, there is no need to pause driving for adjustment, and rapid switching and adjustment can be completed during driving. After the wheelbase adjustment is completed, the tunnel inspection vehicle is driven into the track to be driven, so that the roller assembly conflicts with the track, that is, the track switching is completed, and normal detection driving can be carried out.

[0009] In some embodiments, the adjustment portion includes an adjustment component connected to the detection vehicle body, a support shaft axially connected to the roller component for the roller component to move back and forth to adjust the wheelbase, a clamping member connected to the roller component for driving the roller component to move on the support shaft with the adjustment component to adjust the wheelbase, and a connecting member for connecting the adjustment component and the clamping member.

[0019] Furthermore, an adjustment channel is provided on the device box in the embodiment, and the reinforcement plate and the connecting piece pass through the adjustment channel. When adjusting, the connecting piece moves back and forth in the adjustment channel. The adjustment channel can be used to support and limit the movement range of the connecting piece, thereby ensuring that the connecting piece does not shake up and down, and improving the stability of the adjustment. The two ends of the reinforcement plate are respectively connected to the support shaft and the mounting base, and the middle section of the reinforcement plate is placed on the adjustment channel. The adjustment channel provides support force for the reinforcement plate to ensure the stability of the support shaft.

[0020] At the same time, the adjustment channel confines the connecting parts and reinforcement plates within a unified plane, ensuring that the centers of the support shaft and the roller assembly are on the same straight line, thereby ensuring the connection stability between the roller assembly and the support shaft, making the adjustment smoother and more stable.

[0021] In some embodiments, the adjusting member and the positioning member are connected by threaded connection.

[0022] In some embodiments, the adjustment assembly further includes limit blocks disposed at both ends of the adjustment member for limiting the movement range of the positioning member.
