[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Example 1

[0026] like Figure 1-Figure 4 As shown, the track-road dual-purpose flatbed vehicle comprises an inspection frame 1, a track running mechanism and a road running mechanism installed at the bottom of the inspection frame 1, the center lines of the road running mechanism and the track running mechanism are the same, the track running mechanism comprises a wheel collecting assembly and four track wheels 2 installed on the wheel collecting assembly, and the road running mechanism comprises four tires 3 installed at the bottom of the inspection frame 1, and driven by the wheel collecting assembly, the bottom end of each track wheel 2 is lower than or higher than the bottom end of the tire 3;

[0027] The four track wheels 2 are installed opposite to each other in pairs, and the four tires 3 are installed opposite to each other in pairs, and the wheelbase of the two tires 3 is greater than the wheelbase of the two track wheels 2;

[0028] In this embodiment, the inspection frame 1 is a plate body, and two connecting beams are fixedly connected in sequence along the length direction at the bottom end of the inspection frame 1;

[0029] There are two walking assemblies, which are respectively installed on two connecting beams, and the two wheel-collecting assemblies are symmetrically installed. The wheel-collecting assembly includes a connecting frame 4 and a hydraulic push rod 5 rotatably connected to the connecting beam. One end of the hydraulic push rod 5 is rotatably connected to the bottom end of the inspection frame 1, and one end of the connecting frame 4 away from the inspection frame 1 is rotatably connected to the other end of the hydraulic push rod 5. Track wheels 2 are respectively installed on both sides of the connecting frame 4, and the track wheels 2 are driven to rise and fall below the inspection frame 1 through the extension and retraction of the hydraulic push rod 5.

[0030] Working principle: when walking on the road, the hydraulic push rod 5 contracts to drive the bottom end of the track wheel 2 to be higher than the bottom end of the tire 3, so that the tire 3 is in contact with the ground for walking; when walking on the track, the inspection frame 1 is lifted up to the track and lowered by a crane, and the track wheel 2 and the track are aligned, and the hydraulic push rod 5 is extended to make the track wheel 2 contact with the track, and at the same time the tire 3 leaves the ground, which is convenient for walking on the track.

[0031] In combination with the above, the present application facilitates switching between tracks and roads through the provision of tires 3 and liftable rail wheels 2, increases the applicability of the vehicle body, and effectively solves the problem that current vehicles cannot be used for transporting materials on tracks, roadbed sections, and for the installation of additional lines.

[0032] Example 2

[0033] like Figure 1-Figure 4 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. In this embodiment, in order to facilitate the adjustment of the track wheel 2 by the hydraulic push rod 5, hydraulic support legs 12 are respectively installed on both sides of the inspection frame 1 in the length direction. The number of hydraulic support legs 12 on each side of the inspection frame 1 is two. The inspection frame 1 is supported in advance by the setting of the hydraulic support legs 12, which facilitates the falling and raising of the track wheel 2.

[0034] In this embodiment, at least four hoisting holes 11 are evenly installed on the inspection frame 1, and the inspection frame 1 can be easily hoisted by the arrangement of the hoisting holes 11.

[0035] In this embodiment, a hydraulic telescopic arm 10 is installed between each tire 3 and the inspection frame 1. The moving direction of the tire 3 is perpendicular to the telescopic direction of the hydraulic telescopic arm 10. The hydraulic telescopic arm 10 drives the wheelbase between two opposite tires 3 to change. The variable wheelbase setting of the tire 3 facilitates walking on roads of different widths.

[0036] In order to facilitate the installation of the track wheel 2 on the track, a laser locator 13 compatible with the track wheel 2 is installed at the bottom of the inspection frame 1. The laser locator 13 is located on one side of the track wheel 2. The laser locator 13 is set to perform positioning when the inspection frame 1 descends.

[0037] Example 3

[0038] like Figure 1-Figure 3 As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. In this embodiment, for the convenience of control, a hydraulic station 6 is installed on the inspection frame 1, and the hydraulic push rod 5, the return push rod 9, the hydraulic telescopic arm 10 and the hydraulic support leg 12 are all connected to the hydraulic station 6 to facilitate integrated control.

[0039] At present, the technical solution of this application has been put into pilot production, that is, a small-scale experiment before the large-scale mass production of the product; after the pilot production was completed, a user usage survey was carried out in a small range, and the survey results showed that user satisfaction was high; now we have begun to prepare for the formal production of the product for industrialization (including intellectual property risk warning survey).
